Node B can send data to one or more UE on the uplink at any given time And/or receive data from one or more UE on uplink.Node B also can send control to UE Information processed and/or from UE receive control information.In FIG, there is double-head arrow (such as at node B 110a And between UE 120b) solid line represent on the downlink and uplink data transmission, and The transmission of control information on uplink.There is single arrow of sensing UE (such as UE 120e) Solid line represent data transmission on the uplink, and the biography of control information on uplink Defeated.There is the solid line from single arrow of UE (such as UE 120c) and represent number on uplink According to transmission and the transmission of the information of control.There is the dotted line of single arrow from UE (such as UE 120a) The transmission of expression control information (but not having data) on uplink.For simplicity, The transmission of the control information being shown without in FIG on downlink.Given UE can be any given Moment receives data, on uplink transmission data on the uplink and/or sends out on uplink Send control information.

Fig. 2 illustrates the downlink transmission of node B and the example of the ul transmissions of UE.UE can Periodically estimate the downlink channel quality of node B, and send CQI information to node B.Node B Suitable speed (the example that CQI information is transmitted can be used to downlink (DL) data choosing UE Such as code rate and modulation scheme).When there are data to be sent and system resource can use, node B can process data and send data to UE.The down link data that UE can process from node B passes Defeated, if data are correctly decoded, send confirmation (ACK), if data are decoded incorrectly, send out Send and deny (NAK).If receiving NAK, then node B retransmits data, if receiving ACK, Then can send new data.When there are data to be sent and distributing uplink resource for UE, UE can also send data to node B in up-link (UL).

As in figure 2 it is shown, UE can send data and/or the information of control with arbitrary given interval, Or do not send.Control information is also referred to as control, expense, signaling etc..Control information can include ACK/NAK, CQI, out of Memory or its combination in any.The type sum amount of control information depends on Whether various factors, the quantity of data stream to be sent, use multiple-input and multiple-output (MIMO) It is transmitted.For simplicity, major part description assumes that control information includes CQI and ACK below Information.

System can support mixed automatic retransfer (HARQ), and it is also referred to as steadily increase redundancy, pursuit merges Deng.For the HARQ on downlink, node B can send the transmission of packet, and is dividing Before group is correctly decoded by UE, or before having sent the maximum number of re-transmission, or run into some other Before end condition, one or more re-transmission can be sent.HARQ can improve the reliability of data transmission.

Z HARQ of definable interweaves, and wherein Z can be any integer value.Each HARQ hands over Knit and can include by Z time interval time interval spaced apart from each other.Such as, 6 HARQ of definable hand over Knit, and HARQ intertexture z can include time interval n+z, n+z+6, n+z+12 etc., wherein z ∈{1,…,6}。

HARQ procedure can be described as whole transmission of packet and retransmits (if present).HARQ mistake Journey can when resource can use, and can after the first transmission or one or more subsequently Terminate after re-transmission.When HARQ procedure can have the Variable continuous of the decoded result depending on receptor Between.Each HARQ procedure can be sent on a HARQ interweaves.In one designs, permissible Up to Z HARQ procedure is sent on Z HARQ interweaves.In another designs, can be in phase The different resource (such as, in different subcarrier groups or from different antennas) interweaved with HARQ The multiple HARQ procedure of upper transmission.

Transmission technology described herein can be used for ul transmissions and downlink transmission.These skills Art can be additionally used in various wireless communication system, such as CDMA, TDMA, FDMA, OFDMA With SC-FDMA system.Term " system " and " network " are generally used alternatingly.Cdma system The radiotechnics of embodiment such as general land wireless access (UTRA), cdma2000 etc..UTRA Including wideband CDMA (W-CDMA) and low spreading rate (LCR).Cdma2000 contain IS-2000, IS-95 and IS-856 standard.Tdma system embodiment such as global system for mobile communications (GSM) Radiotechnics.The UTRA (E-UTRA) of OFDMA system embodiment such as evolution, IEEE 802.11, IEEE 802.16, IEEE 802.20, flash type-(Flash-) etc. Radiotechnics.These radiotechnics and standard are known in the art.UTRA, E-UTRA and GSM is a part of UMTS (UMTS).Long Term Evolution (LTE) is to use The future version of the UMTS of E-UTRA.At entitled " third generation partner program " (3GPP) Tissue document in describe UTRA, E-UTRA, GSM, UMTS and LTE.Entitled " Third generation partnership project 2 " (3GPP2) tissue document in describe cdma2000.In order to clearly Chu Qijian, describe hereinafter some aspect of the technology of ul transmissions in LTE, And in following major part describes, use 3GPP term.

LTE utilizes Orthodoxy Frequency Division Multiplex (OFDM), on uplink profit on the uplink With single carrier frequency division multiplexing (SC-FDM).System bandwidth is divided into many by OFDM and SC-FDM Individual (N number of) orthogonal sub-carriers, these orthogonal sub-carriers are also commonly referred to as tone, frequency band etc..Can Each subcarrier is modulated by data.Generally, utilize in a frequency domain OFDM to send modulation symbol, Utilize SC-FDM to send modulation symbol in the time domain.For LTE, adjacent sub-carrier it Between interval can be fixing, and the sum (N) of subcarrier depends on system bandwidth.In one In design, N=512 for the system bandwidth of 5MHz, for 10MHz system bandwidth and Speech N=1024, N=2048 for the system bandwidth of 20MHz.Generally, N can be the most whole Numerical value.

Fig. 3 illustrates the design that can be used for sending the structure 300 of data and the information of control on uplink. Transmission time shaft is divided into multiple subframe.Subframe can have a fixing persistent period, such as 1 millisecond , or the configurable persistent period (ms).Subframe can be divided into 2 time slots, and each time slot can include L Individual symbol period, wherein L can be any integer value, such as L=6 or 7.Each symbol period can For data, control information, pilot tone or its combination in any.

In the design shown in Fig. 3, N total subcarriers is divided into data division and control part. Part is controlled as it is shown on figure 3, can be formed at the edge of system bandwidth.Control part has configurable Size, described size can be selected based on the amount of the control information sent by UE on uplink Select.Data division includes all subcarriers being not included in control part.In the design of Fig. 3, Data division includes the subcarrier adjoined, thus allows all neighbours in single UE distribution data division The subcarrier connect.

Can have a control section of M contiguous subcarrier to UE distribution, wherein M can be fixed value or Configurable value.Control section is also referred to as physical uplink control channel (PUCCH).Set in one In meter, control section can include the integral multiple of 12 subcarriers.Also can have Q to UE distribution to adjoin The data segment of subcarrier, wherein Q can be fixed value or configurable value.Data segment is also referred to as thing Reason uplink shared channel (PUSCH).In one designs, data segment can include that 12 sons carry The integral multiple of ripple.In given subframe, it is also possible to not to UE distribution data segment or control section.

For UE it is desirable that, use SC-FDM to be transmitted on adjacent subcarrier, it is referred to as Localized frequency division multiplexing (LFDM).On adjacent subcarrier, transmission can cause relatively low peak-to-average force ratio (PAR).PAR is waveform peak power and wave-average filtering power ratio.Owing to allowing power amplifier (PA) running under the average output power of maximum output, so low PAR is expectation 's.So can improve handling capacity and/or the link margin of UE.

The control section of system bandwidth adjacent edges can be positioned to UE distribution.When having data to send, also Can be to the data segment in UE distribution data division.The subcarrier of control section and the subcarrier of data segment not phase Adjacent.If not having data to send, then UE can send control letter in control section Breath.If having data on uplink send, then UE can send data and control in data segment Information processed.In spite of having data to send, this dynamic transmission controlling information can make UE neighbour Send control information on the subcarrier connect, thus PAR can be improved.

Fig. 4 A illustrates the transmission of control information when not having data to send in subframe. Control section can be distributed to UE, described control section is mapped to the different sub carrier in two time slots of subframe Group.UE can send on the subcarrier of the control section distributed in each symbol period and control letter Breath.Residue subcarrier can be by other UE for ul transmissions.

Fig. 4 B illustrates data and the transmission of the information of control when having data on uplink send.Can be to UE distributes data segment, by the different sub carrier group in two time slots of described data section mapping to subframe. UE can send data and control in each symbol period on the subcarrier of the data segment distributed Information.Residue subcarrier can be by other UE for ul transmissions.

Fig. 4 A and 4B illustrates the frequency hopping between time slot.Can also be in such as week from symbol period to symbol Phase, interval At All Other Times from subframe to subframe etc. perform frequency hopping.Frequency hopping can provide frequency diversity to prevent Disadvantageous path effects and the randomness of interference.

System can support FDD (FDD) pattern and/or time division duplex (TDD) pattern.At FDD Under pattern, independent channel can be used for downlink and up-link, can be at their independent channel Upper transmission downlink transmission and ul transmissions simultaneously.In tdd mode, common channel can be used In downlink and up-link, downlink transmission can be sent in some time period, when other Between section send ul transmissions.

Fig. 5 illustrates the time structure 500 that can be used for tdd mode.Transmission time shaft is divided into multiple frame Unit.Each frame may span across predetermined persistent period, such as 10ms, and can be divided into predetermined number Purpose subframe.In each frame, N is distributed for downlink_DLIndividual subframe, distributes N for up-link_UL Individual subframe.N_DLAnd N_ULCan be the value being arbitrarily suitable for, be also based on downlink and up-link Flow load and/or other reason configure.

Configuring according to system, downlink and up-link can have symmetry or asymmetric distribution. For symmetrical downlink and up-link distribution, the number of downlink subframe is equal to up The number of link subframe, or N_DL=N_UL.Each downlink subframe can be with corresponding up-link Subframe is associated.For example, it is possible to send data transmission in downlink subframe n, on corresponding In uplink subframe n send data transmission control information, wherein n ∈ 1 ..., N_DL}.For the most right For the downlink claimed and up-link distribution, the number of downlink subframe and uplink sub-frames Number do not mate, or N_DL≠N_UL.Therefore, may between up-link and downlink subframe Existing is not man-to-man mapping.Asymmetric distribution can allow flexible system resource to distribute, with Matched load condition, but system operation can be made to complicate.

Fig. 6 illustrates the exemplary data transmission of the asymmetric distribution of downlink and up-link.At this In individual example, M downlink subframe 1 to M can be associated with single uplink sub-frames, its Middle M can be any integer value.Can be to UE allocation of downlink subframe 1 to M and association Resource in uplink sub-frames.Can send about M to UE in M downlink subframe M packet of HARQ procedure.The each packet of UE decodable code, and determine the ACK information of packet. ACK information is also known as ACK feedback, and can include ACK or NAK.UE can be in up-link Frame sends the ACK information of all M packets.In figure 6, ACK1 be sent about The ACK information of the packet of HARQ procedure H1, ACKM be sent about HARQ procedure The ACK information of the packet of HM, wherein H1 to HM can be the most available HARQ procedure. ACK information can be used for controlling the re-transmission of the packet of transmission or the decoded in error being newly grouped.

On the one hand, variable control channel is for supporting the symmetrical and the most right of downlink and up-link Claim distribution.Such as, according to whether send data, distribute different amounts of resource to controlling channel.Can make Different types of control information and/or different amounts of control information is sent neatly with controlling channel.
