Implement mode of the present invention
The embodiment of the present invention provides a kind of method of SR information and ACK/NACK information feedback or a plurality of SR information feedback.Below the technical scheme of the embodiment of the present invention is described in further detail.
The inventor, in realizing the process of the embodiment of the present invention, finds in prior art, and the SR of take is example during as Positive, need be at SRI transmitted over resources 2 bit informations, and this 2 bit information means NACK or ACK number.If base station receives NACK, the PDSCH which subframe base station can not judge does not correctly receive, and the PDSCH of a plurality of subframes needs to retransmit, and has increased unnecessary transfer of data, affects the PDSCH efficiency of transmission, reduces downlink throughput capacity.For LTE FDD system, there is no descending allocation index DAI (DAI:Downlink Assignment Index) bit in Downlink Control Information DCI (DCI:Downlink Control Information), if support many ACK/NACK and the multiplexing rear transmission simultaneously of SR in LTE-A FDD system by the mechanism of LTE TDD, just need to introduce extra DAI bit, can introduce new DCI form for FDD like this.
Fig. 1 is the embodiment schematic diagram that UE of the present invention feeds back SR information and ACK/NACK information simultaneously, and the present embodiment comprises:
The present embodiment is applicable to UE in LTE, LTE-A system and feeds back the process of SR information and ACK/NACK information at a sub-frame of uplink simultaneously.The executive agent of the present embodiment is UE.
In the present embodiment, before step 101, SRI channel and the ack channel of SR feedback cycle, correspondence can be distributed to UE in base station.UE can be mapped as ACK, NACK or DTX by the SR information content to be feedback.UE just can send SR information to be feedback with ACK/NACK information to be feedback together according to the feedback system of ACK/NACK like this.UE can line up SR information and ACK/NACK information and form the feedback information set, SRI channel and ack channel are lined up to form and distribute the PUCCH channel set, select at least one transmission channel according to preset rules according to above-mentioned SR information and ACK/NACK information from above-mentioned SRI channel and ack channel again, map out transmission information bit, finally by the transmission channel of selecting, send above-mentioned transmission information bit.Below each step is described in detail.
SR information is used for UE to base station requests transmitting uplink data resource.To 3GPP LTE system, base station is come for UE configuration SR feedback cycle and corresponding SRI channel by high-level signaling.To the 3GPPLTE-A system, when for LTE-AUE, having configured a plurality of upstream components carrier wave, can be SRI channel of each upstream components allocation of carriers, or be common SRI channels of a plurality of upstream components allocation of carriers.The mode of distribution SRI channel can be identical with the SRI Channel distribution mode of LTE system.If current sub-frame of uplink base station constantly is that the SRI channel number that UE distributes is K, channel indexes is respectively
wherein K is positive integer.K SRI channel correspondence the feedback of K SR information.To LTE UE, K=1; To LTE-A UE, consider dispatch request and upstream components carrier wave normally independently, no matter its upstream components carrier wave configuring condition of hypothesis in the present embodiment has K=1.If UE does not constantly need to feed back SR information at current sub-frame of uplink, K=0 is arranged, the embodiment of the present invention is that to take the method that UE feeds back SR information and ACK/NACK information simultaneously be example, thereby K is positive integer.
Whether ACK/NACK information is correctly received to the TB of the upper transmission of base station feedback PDSCH for UE.To 3GPP LTE TDD system, according to its ratio of uplink subframe to downlink subframe, arrange, need to constantly feed back at a sub-frame of uplink ACK/NACK information of the TB transmitted on a plurality of descending sub frame PDSCH; To 3GPP LTE-A FDD system, according to the downlink component carrier configuration of UE, need to constantly feed back at a sub-frame of uplink ACK/NACK information of the TB transmitted on the PDSCH of a plurality of downlink component carriers; For 3GPP LTE-A TDD system, according to the downlink component carrier configuration of UE and the ratio of uplink subframe to downlink subframe setting of each component carrier, need to constantly feed back at a sub-frame of uplink ACK/NACK information of the TB transmitted on a plurality of descending sub frame PDSCH of a plurality of downlink component carriers.
For LTE and LTE-A UE, if adopted MIMO technique, a PDSCH also may transmit a plurality of TB, corresponding a plurality of ACK/NACK information.Two kinds of ACK/NACK feedback schemes are arranged in this case:
Scheme one, the multiple-input and multiple-output ACK/NACK feedback scheme of binding, wherein UE will with a plurality of TB respectively corresponding a plurality of ACK/NACK information exchanges cross the logical AND operation and obtain an ACK/NACK information and feed back to base station;
Scheme two, multiple-input and multiple-output ACK/NACK feedback scheme independently, wherein UE will with a plurality of TB respectively corresponding a plurality of ACK/NACK information all feed back to base station.
In a word, establishing the ACK/NACK information number that UE will feed back is L
0, this L
0individual ACK/NACK information may, from different downlink component carriers, may, from different descending sub frames, may be also the different TB from the upper transmission of a descending sub frame PDSCH, wherein L
0it is positive integer.
According to descending carrier and/or the ratio of uplink subframe to downlink subframe setting of configuration, UE can determine L according to the actual PDSCH received and multiple-input and multiple-output ACK/NACK feedback scheme
0value.For example, to LTE-A FDD system, be assumed to be UE and configured 4 downlink component carriers, and adopt the multiple-input and multiple-output ACK/NACK feedback scheme of binding, when UE 2 component carriers in 4 component carriers receive PDSCH, L
0=2.
According to descending carrier number and/or the ratio of uplink subframe to downlink subframe setting of configuration, the PDSCH that UE can also receive according to maximum possible and multiple-input and multiple-output ACK/NACK feedback scheme are determined L
0value.For example, to the LTE-ATDD system, be assumed to be UE and configured 4 downlink component carriers, 4 descending sub frame feeding back ACK/nack messages a sub-frame of uplink moment to each downlink component carrier, and adopt the multiple-input and multiple-output ACK/NACK feedback scheme of binding, may receive PDSCH, L at each descending sub frame of 4 downlink component carriers at most at a sub-frame of uplink moment UE so
0=4 * 4=16.In system can according to, for example first descending sub frame again the order of downlink component carrier by L
0individual ACK/NACK information is arranged.As UE, when certain descending sub frame of certain downlink component carrier is not received PDSCH, corresponding ACK/NACK information value is DTX.
For 3GPP LTE and LTE-A system, the sub-frame of uplink of UE feeding back ACK/nack message has a predefined time delay constantly and between the moment of reception descending sub frame PDSCH; The ack channel resource that feeding back ACK/nack message is used is by the channel indexes of distributing
identify, the control channel element numerals taken by PDCCH when the PDSCH transmission has corresponding PDCCH transmission is shone upon and is obtained
when having corresponding PDCCH transmission, the PDSCH transmission do not show configuration by high-level signaling
the ack channel number that is made as the UE distribution is L, and channel indexes is respectively
wherein L is positive integer.According to transmittability and the ACK/NACK information feedback scheme of ack channel, L and L
0can not wait, for example in LTE FDD system, for 1 bit and 2 bit ACK/nack message feedback, all only distributed 1 ack channel.In embodiments of the present invention, suppose L=L
0.When PDSCH and multiple-input and multiple-output ACK/NACK feedback scheme that UE receives according to maximum possible are determined L
0during value, if do not receive PDSCH in certain subframe of certain component carrier, corresponding ACK/NACK information value is DTX, and the ack channel now distributed is the ack channel of virtual assigned.
For the LTE-A system, UE can adopt a plurality of transmitting antennas to send information at uplink direction simultaneously, may introduce the transmission diversity technique of PUCCH channel, the ACK/NACK information of a descending sub frame or a SR information may need Q ack channel or SRI channel, and wherein Q is positive integer.At this time, the SRI channel distributed in foregoing description and ack channel should be respectively K and L group, and wherein every group has Q channel.In the expansion of the step embodiment of the present invention is described, all be based on and do not introduce that situation that the PUCCH channel sends diversity technique describes, when having introduced PUCCH channel transmission diversity technique, should change a SRI channel in the embodiment of the present invention into one group of SRI channel, an ack channel changes one group of ack channel into, and a PUCCH channel changes one group of PUCCH channel into.
Suppose that UE can parallel transmission P PUCCH channel constantly at sub-frame of uplink, wherein P is positive integer.For LTE UE, P=1; For LTE-A UE, according to UE carrier wave and antenna configuration ability and/or channel condition situation etc., possible configuration P >=1.
In the LTE system, ack channel and SRI channel have identical channel architecture, and the SRI channel also can transferring ACK/NACK modulation symbol, as ack channel, use.If the ACK/NACK information bit number that each ack channel or SRI channel can feed back is A.
When UE has SR information and ACK/NACK information to feed back simultaneously, first according to a definite sequence by K SR information and L
0individual ACK/NACK information and K the SRI channel and L the ack channel that distribute are lined up, and form feedback information set HARQ-ACK (0) ..., HARQ-ACK (K+L
0-1) and distribute the PUCCH channel set
putting in order of a kind of example is first to arrange ACK/NACK information and ack channel, then arranges SR information and SRI channel, i.e. i (0≤i≤L
0-1) the corresponding feedback information set element of the individual ACK/NACK information individual SR information of corresponding feedback information set element HARQ-ACK (i), i (0≤i≤K-1) HARQ-ACK (i+L
0), the corresponding PUCCH channel set element that distributes of the individual ack channel of i (0≤i≤L-1)
the corresponding PUCCH channel set element that distributes of the individual SRI channel of i (0≤i≤K-1)
the value of each feedback information set element can be ACK, NACK or DTX.For SR information, the value of corresponding feedback information set element can be mapped as NACK or DTX when SR information value is negativeSR, when SR information value is positive SR, can be mapped as ACK.
Above-mentionedly according to a kind of default channel selective rule, select at least one channel and map out information bit to be transmitted and can be specially: according to feedback information set HARQ-ACK (0) ..., HARQ-ACK (K+L
0-1) element value, press certain way from distributing the PUCCH channel set
in select P PUCCH channel, and map out A * P information bit to be transmitted.When PDSCH and multiple-input and multiple-output ACK/NACK feedback scheme that UE receives according to maximum possible are determined L
0during value, selected P PUCCH channel can not comprise the ack channel of virtual assigned.The above-mentioned certain way PUCCH channel that can be system predefine select from distribute the PUCCH channel set according to feedback information set element value and the look-up table of information bit to be transmitted, as the multiplexer mode transmission look-up table of the ACK/NACK information that defines in the LTE system, in Table 1, table 2 and table 3.In table 1, table 2 and table 3, UE can obtain a PUCCH channel of selecting and 2 bits information bit to be transmitted at every turn.
Shown in the PUCCH channel that the said system predefine of below take is selected from distribute the PUCCH channel set according to feedback information set element value and look-up table employing table 1, table 2 and the table 3 of information bit to be transmitted, look-up table, as example illustrates, now has L
0=L, A=2.
When P=1, UE is according to SRI channel and ack channel number K+L, select corresponding form, then select 1 transmission channel according to preset rules according to above-mentioned SR information and ACK/NACK information from above-mentioned SRI channel and ack channel, and map out 2 transmission information bit.Below for K=1, L value, be respectively 1,2 or illustrate respectively at 3 o'clock.In example, negative SR is mapped as DTX, and positive SR is mapped as ACK; UE, according to a plurality of ACK/NACK information contents, selects an ack channel, and maps out two transmission information bit.
