upper, adopt PUCCH format 1b to detect ACK/NACK, obtain dynamic PDSCH on PCC and SPS PDSCH corresponding many TB of the 1 bit ACK/NACK information [ACK, NACK] after merging respectively; If according to ACK/NACK being detected in the definite PUCCH resource of the minimum CCE of PDCCH of scheduling PCC, the PDSCH of the PDCCH scheduling that terminal has received that DAI value is 1 is described, otherwise lost terminal the has been described PDSCH of the DAI value PDCCH scheduling that is 1, has only received SPS PDSCH.
It should be noted that, it is that the PDCCH of 1 indicating downlink SPS resource release is applicable equally that the PDSCH of the PDCCH scheduling that is 1 by DAI value of the upper transmission of above-mentioned PCC is replaced with to DAI value, because it only comprises 1TB, does not need to do space merging.
Referring to Figure 12, the present embodiment is applied in TDD system, and when PCC is many codeword transmission pattern, the method flow of the third transmitting uplink control information is as follows:
Suppose that terminal adopts PUCCH format 1b with channel selection transferring ACK/nack message, and adopt 2 antenna ports to transmit.
Under TDD system, the schematic diagram of scheduling of resource and feedback is shown in Figure 13.
Step 1201: the DAI value of base station by scheduling PCC is greater than the channel resource group that transmit for 2 antenna ports to terminal configuration in the TPC territory in the PDCCH of 1 PDCCH and scheduling SCC.For example, in this group, comprise 4 PUCCH channel resources
tPC territory indication same asset group in a plurality of PDCCH.
Step 1202: terminal only receives the PDSCH of the PDCCH scheduling that 1 is 1 by DAI value at PCC.For example, this PDSCH comprises 1 TB, and 1 PDSCH without corresponding PDCCH (being SPS PDSCH).Terminal is not received the PDCCH of the channel resource indication information that comprises many antenna port transmission uses.
Step 1203: terminal is determined the PUCCH format 1b with channelselection transferring ACK/NACK feedback information that adopts single-port mode.Specifically there are following three kinds of modes:
Mode one: terminal can be according to single carrier operation mode, only PCC is reused the ACK/NACK information [ACK of PUCCH format 1b with channel selection transmission plan feedback PCC of the single-port mode of Rel-8, ACK, NACK, NACK], wherein every bit feedback information is the space combinatorial construction of the ACK/NACK information of many TB corresponding to this subframe, to not receiving that the subframe of data produces NACK, can carry out channel selection according to 4 bit mapping forms in the configuration employing Rel-8 of high-level signaling or 4 bit mapping forms in Rel-10; Candidate channel resource comprises 1 PUCCH resource determining according to the TPC territory indication information that activates the PDCCH of SPS PDSCH
this resource is the 1st resource that subframe is corresponding (i.e. resource corresponding to 1st bit ACK/NACK), also comprises according to the minimum CCE numbering of the PCC PDCCH that above DAI value is 1 and determines 1 PUCCH resource
this resource is the 2nd resource that subframe is corresponding (i.e. resource corresponding to 2nd bit ACK/NACK), owing to not receiving data in upper latter two subframe of PCC, so uncertain latter two resource.
Mode two: terminal can be according to single carrier operation mode, reuse the PUCCH format 1b with channel selection transmission plan of the single-port mode of Rel-8, only to receiving the subframe of data on PCC, carry out ACK/NACK feedback, do not need the ACK/NACK feedback information of many code words to carry out space merging.That is:
If determine number of bits of feedback according to transmission mode, because PCC is many codeword transmission pattern, adopt 4 bit ACK/NACK mapping form, 4 bit ACK/nack message is respectively 1 bit ACK of SPS PDSCH and the NACK that the TB2 position of this subframe is produced, and 1 bit ACK of each TB receiving in the PDSCH of the PDCCH that is 1 by DAI value scheduling, be that feedback sequence is [ACK, NACK, ACK, ACK], candidate channel resource is 2 PUCCH resources determining according to the TPC territory indication information that activates the PDCCH of SPS PDSCH
with
and the minimum CCE numbering of the PDCCH that is 1 according to the upper DAI value of PCC is determined 1 PUCCH resource
with
corresponding with ACK/NACK feedback bits successively.
Or, if determine number of bits of feedback according to the actual data that receive, because SPS PDSCH itself is 1TB transmission, the PDSCH of the PDCCH that is 1 by DAI value scheduling comprises 2 TB, adopt 3 bit ACK/NACK mapping form, 3 bit ACK/nack message is respectively 1 bit ACK of SPS PDSCH, and 1 bit ACK of each TB receiving in the PDSCH of the PDCCH that is 1 by DAI value scheduling, be that feedback sequence is [ACK, ACK, ACK], candidate channel resource is 1 PUCCH resource determining according to the TPC territory indication information that activates the PDCCH of SPS PDSCH
and the minimum CCE numbering of the PDCCH that is 1 according to the upper DAI value of PCC is determined 2 PUCCH resources
with
corresponding with ACK/NACK feedback bits successively.
It should be noted that, it is that the PDCCH of 1 indicating downlink SPS resource release is applicable equally that the PDSCH of the PDCCH scheduling that is 1 by DAI value of the upper transmission of above-mentioned PCC is replaced with to DAI value, because it only comprises 1TB, adopt 2 bit ACK/NACK mapping form, 2 bit ACK/nack message is respectively 1 bit ACK of SPS PDSCH, and 1 bit ACK of the PDCCH that discharges of the DAI value indicating downlink SPS resource that is 1, be that feedback sequence is [ACK, ACK], candidate channel resource is 1 PUCCH resource determining according to the TPC territory indication information that activates the PDCCH of SPS PDSCH
and the minimum CCE numbering of the PDCCH that is 1 according to the upper DAI value of PCC is determined 1 PUCCH resource
corresponding with ACK/NACK feedback bits successively.
Mode three: terminal can be according to multicarrier working method, the PUCCHformat 1b with channel selection transmission plan of reusing the single-port mode of Rel-10 feeds back the ACK/NACK information of a plurality of CC, because the number of sub frames on each carrier wave surpasses 2, need to carry out time domain merging to the ACK/NACK on each carrier wave; Can carry out channel selection according to 4 bit mapping forms corresponding to time domain Merge Scenarios in Rel-10; Definite mode of candidate channel resource is the same.
Step 1204: the PUCCH format 1bwith channel selection transmitting uplink control information that terminal adopts single antenna port to send according to definite resource.
Step 1205: the PDCCH that base station is greater than 1 PDCCH and dispatches SCC in the DAI value by scheduling PCC configures 4 PUCCH channel resources to terminal
upper, according to ACK/NACK mapping form, ACK/NACK information do not detected.Base station determines that terminal all exists packet loss at PCC and SCC, retransmits all data.
Step 1206: base station adopts PUCCH format 1b with channel selection to detect ACK/NACK.Concrete, the PUCCH resource of indicating in the TPC territory of activating the PDCCH of SPS PDSCH
upper, the definite PUCCH resource of minimum CCE of the PDCCH that is 1 according to the DAI value of scheduling PCC
upper, and the DAI value of scheduling SCC is the definite PUCCH resource of minimum CCE of 1 and 2 PDCCH
with
upper, detect ACK/NACK, counter tabling look-up obtains ACK/NACK information.
