Description
Technical field
The present invention relates to wireless communication system, particularly a kind of transmission mixes the method for automatic repeat requests feedback (ACK/NACK) information resources indication.
Background technology
At present, the maximum bandwidth of Long Term Evolution (LTE) system is 20MHz, in order to satisfy the more demand of high data rate, on the basis of LTE, has proposed enhancing Long Term Evolution (LTE-A) system again.In the LTE-A system, obtain bigger bandwidth of operation through making up a plurality of unit carrier wave (CC), constitute communication system down link and up link respectively, i.e. carrier combination (CA) technology, thus support higher transmission rate.For example, in order to support the bandwidth of 100MHz, can obtain through the CC that makes up 5 20MHz.
Based on CA; Downlink data is sent to same user terminal (UE) in the base station on a plurality of CC; Correspondingly; UE need support to send the automatic repeat requests of mixing (HARQ) feedback information to the downlink data that on a plurality of CC, sends, and promptly feedback receives successfully (ACK) or (NACK) information that takes defeat, and in subsequent descriptions, is expressed as ACK/NACK information.
According to the discussion result of present LTE-A, go up the ACK/NACK information of transfer of data to each CC and on a up CC, send, promptly need send the ACK/NACK information of many bits.In view of this, in LTE-A, adopted a kind of channel format of new ACK/NACK information, promptly based on the ascending control channel form of the OFDM (DFT-S-OFDM) of DFT expansion.As shown in Figure 1; At first ACK/NACK information is carried out chnnel coding and rate-matched (the specific scrambling in the sub-district in the corresponding diagram 1) and carry out QPSK (QPSK) modulation obtaining 24 QPSK symbols, these 24 QPSK symbols are divided into two groups of interior transmission of two time slots that also are mapped to sub-frame of uplink respectively.To each time slot; If it is SF that note is used to carry the number of OFDM (OFDM) symbol of ACK/NACK information; Correspondingly the length of quadrature temporal extension sign indicating number (OCC) is SF, and then 12 QPSK symbol repeating mapping and are used unit's weighting usually of OCC respectively to SF OFDM symbol.Next, the weighted Q PSK symbol on each OFDM symbol is carried out DFT (DFT) precoding (being Pre-DFT), and carry out invert fast fourier transformation (IFFT) and change to time domain and obtain the ACK/NACK information that to send.The precoding here is identical with the Pre-DFT conversion of sending upstream data, in LTE-A, calls ascending control channel (PUCCH) form 3 to the channel format of this ACK/NACK information at present.
In LTE-A, the base station is through high-level signaling configuration UE downlink data receiving on a plurality of CC, and the CC quantity of actual schedule can be less than or equal to the high-rise CC quantity that disposes in a sub-frame.Such as, the CC quantity through the high-level signaling configuration among Fig. 2 is 4, is respectively CC 1 to CC 4, and CC of base station actual schedule, promptly CC 1.For another example, the CC quantity through the high-level signaling configuration among Fig. 3 is 4, is respectively CC 1 to CC 4, and 3 CC of base station actual schedule, i.e. CC 0, CC 1 and CC 2.In a plurality of descending CC of base station through the high-level signaling configuration, one of them is main CC (PCC), and other CC are called time CC (SCC).UE can change the method for feeding back ACK/NACK channel according to whether having received the data of SCC when feeding back ACK/nack message.Be specially: when UE only received downlink data on PCC, scene and LTE were similar, and UE can be according to the method for LTE according to the definite PUCCH form 1a/1b channel that will use of PDCCH, thereby comes feeding back ACK/nack message with the method among the LTE; When UE has received a SCC at least, this UE real work is described under the CA pattern, then can confirm PUCCH form 3 channels that will use according to ACK/NACK information resources indication (ARI), thus on the channel of confirming feeding back ACK/nack message.Also can under above-mentioned two kinds of situation, all utilize PUCCH form 3 channels to come feeding back ACK/nack message.Wherein, ARI is used for indication and distributes to the resource that UE is used for feeding back ACK/nack message.
In order to support the method for above-mentioned feeding back ACK/nack message, need to confirm the sending method of ARI.Present existing proposed way is: through-put power control (TPC) territory among the multiplexing PDCCH.Be specially: transmission power control commands still in the TPC territory of the PDCCH of PCC guarantees that the base station can control the transmitting power of UE; Simultaneously, in the TPC territory of the PDCCH of SCC, send ARI.But; If UE does not have correctly to receive the PDCCH of PCC; Perhaps the current dynamic data of not dispatching on the PCC in base station then adopts this mode UE just can not obtain power control command, thereby possibly influence the correct transmission of the ACK/NACK information of up PUCCH form 3 channels.

Embodiment
In order to make the object of the invention, technical scheme and advantage clearer, describe the present invention below in conjunction with accompanying drawing and specific embodiment.
Based on the downlink data communication of CA generally all is to be purpose with higher peak rate and bigger downlink throughput capacity, so for the UE based on CA, it is fewer that its number of times that retransmits to HARQ of downlink data transmission generally can be controlled.In typical case, only needing HARQ to retransmit to the downlink data transmission based on the UE of CA just can be successful.Under the situation of CA, only need 1 bit redundancy versions (RV) information just to can be good at having supported downlink data transmission.
In view of in LTE, the RV territory among the PDCCH is a dibit.Based on top analysis, overcharge the PDCCH form of (SIMO) to dispatching single-shot, have only a RV territory, then can obtain the bit of a redundancy; PDCCH form to scheduling MIMO (MIMO) wherein has two RV territories, then can use this method to obtain the bit of two redundancies.These redundant bits can be used to indicate ARI information.
Based on above-mentioned analysis, the present invention provides the main method of sending ARI to comprise: in the PDCCH of scheduling SIMO, send transmission power control command, RV information and ARI information through TPC territory and RV territory; In the PDCCH of scheduling MIMO, send transmission power control command through the TCP territory, and send RV information and ARI information through two RV territories, perhaps send transmission power control command, RV information and ARI information through TPC territory and RV territory.
Correspondingly, UE holds the main method of obtaining ARI to comprise: in the PDCCH of scheduling SIMO, obtain transmission power control command, RV information and ARI information through TPC territory and RV territory; In the PDCCH of scheduling MIMO, from the TPC territory, obtain transmission power control command, and obtain ARI information and RV information through two RV territories, perhaps, obtain transmission power control command, RV information and ARI information through TPC territory and RV territory.
In LTE, can support the transmission power control command of two kinds of granularities, if the i.e. transmission power control command of transmission dibit, corresponding power control value is [1013] dB, expression can for-1,0,1 or 3dB in one; If transmit the transmission power control command of a bit, corresponding power control value is [11] dB, expression can for-1 or 1dB in one.But the TPC territory among the LTE among the PDCCH of dispatching downlink transfer of data can only be two bits.In method provided by the invention, in the PDCCH of dispatching downlink transfer of data, send the transmission power control command of a bit at least, thereby make UE can obtain transmission power control command from the TPC territory.
Specifically,, the transmission power control command of a bit be can send, then can redundancy the ARI information of the multiplexing back transmission of a bit and RV territory dibit and the RV information of a bit be gone out in the TPC territory the PDCCH of scheduling SIMO.PDCCH to scheduling MIMO; Can keep the TPC territory of 2 bits still to be used to transmit transmission power control information; Promptly do not obtain can be used for the bit of other functions from the TPC territory, the ARI information of dibit and the bit RV information that each transmission block (TB) is transmitted are respectively transmitted in only multiplexing two RV territories; To the scheduling MIMO PDCCH also can with the similar method of SIMO; Only send the transmission power control command of a bit, can redundancy go out the ARI information of the multiplexing back transmission of a bit and RV territory dibit and a bit RV information of transmitting respectively to each TB in the TPC territory.
Wherein, The implication of the transmission power control command of one bit can be identical with the implication of the transmission power control command of a bit among the existing LTE, and promptly [11] dB also can be other definition; [01] dB for example; This definition can guarantee that under stable situation, the uplink transmission power of UE does not fluctuate, and can be through increasing the reliability that power improves PUCCH form 3 channels when the channel condition variation.
The corresponding flow chart of above-mentioned main method can be as shown in Figure 4, step 401: according to the PDCCH form is to be used for SIMO or MIMO handles respectively, for the PDCCH execution in step 402 of scheduling SIMO, for the PDCCH execution in step 403 of scheduling MIMO.
Step 402: in the PDCCH of scheduling SIMO, power control command, a bit RV information and the dibit ARI information of a bit is transmitted in multiplexing TPC territory and RV territory.
Step 403: in the PDCCH of scheduling MIMO, can have two kinds of methods to transmit ARI information.First method is to keep the TPC territory to carry the dibit power control commands, the bit RV information that multiplexing two RV territories are transmitted dibit ARI information and each TB is transmitted respectively.Second method is power control command, the dibit ARI information that a bit is transmitted in multiplexing TPC territory and RV territory; The bit RV information that each TB is transmitted respectively; Also have this idle bit of bit of a free time to can be used for other purposes in addition, the present invention does not limit.
According to the concrete configuration method of ARI information, enumerate two preferred embodiments below:
Embodiment one, when sending ARI on the PDCCH only at SCC, the base station adopts diverse ways to handle the PDCCH of PCC and SCC.As shown in Figure 5, mainly may further comprise the steps:
Step 501: base station dispatcher is UE allocation of downlink data transmission resources on a plurality of CC.
Here the base station downstream data channel that possibly only distribute PCC for UE, the downstream data channel of perhaps only having distributed SCC, perhaps the while has been distributed downstream data channel on PCC and SCC.
Step 502: according to scheduling result; The PDCCH that each CC of scheduling goes up data is sent in the base station, wherein, and in the PDCCH of PCC; The base station is according to the form of PDCCH among the existing LTE; Promptly TPC territory and RV territory are not reset, be specially: the TPC territory is the power control command of 2 bits, and the RV territory of each TB is the RV information of dibit.And in the PDCCH of SCC, adopt mode provided by the invention to send RV information and the ARI information of transmission power control command, each TB, the method shown in Fig. 4 for example.
Step 503: the base station is according to the control information of indicating among current scheduling result and the PDCCH, on each CC, sends the downlink data of current scheduling for UE.
Step 504: the ACK/NACK feedback information is detected according to the situation of its actual transmission downlink data in the base station.
In this step, when downlink data has only been dispatched for UE in the base station on PCC, only in the PDCCH of PCC, according to receiving ACK/NACK information on the channel that the PUCCH form is corresponding among the existing LTE, i.e. reception ACK/NACK information on PUCCH form 1a/1b channel.When data have only been dispatched for UE in the base station on SCC, reception ACK/NACK information on PUCCH form 3 channels of the indication of the ARI in the PDCCH of SCC only then.When transfer of data has been dispatched simultaneously in the base station on PCC and SCC; The base station is in the PDCCH of PCC; Receive ACK/NACK information on the PUCCH form 1a/1b channel, and blind Detecting ACK/NACK information on PUCCH form 3 channels of the indication of the ARI in the PDCCH of SCC.Here the reason of blind Detecting is: when transfer of data has been dispatched simultaneously in the base station on PCC and SCC; UE might only receive that PCC goes up the data of scheduling, thus can the PDCCH of scheduling PCC according to the corresponding PUCCH form 1a/1b channel of the rule of LTE on feeding back ACK/nack message.
Corresponding with the operation of base station, when sending ARI on the PDCCH at SCC only, UE adopts diverse ways to handle the PDCCH of PCC and SCC.As shown in Figure 6, mainly may further comprise the steps:
Step 601:UE receives the PDCCH (UE possibly only receive the PDCCH of PCC, perhaps only receives the PDCCH of SCC, perhaps receives the PDCCH of PCC and SCC simultaneously) that send the base station.When UE received the PDCCH of PCC, UE did not reinterpret TPC territory and RV territory, promptly obtained the transmission power control command of 2 bits from the TPC territory, obtained the RV information of dibit from the RV territory.When UE receives the PDCCH of SCC, obtain transmission power control command, RV information and ARI information through demultiplexing TPC territory and RV territory; Perhaps from the TPC territory, obtain transmission power control command, two RV territories of demultiplexing obtain RV information and ARI information.
Step 602: the base station receives the downlink data that send the base station according to the control information among each PDCCH that receives on each CC, and generates the ACK/NACK feedback information.
Step 603:UE sends the ACK/NACK feedback information.When UE only receives data on PCC, in the PDCCH of PCC according to LTE in feeding back ACK/nack message, i.e. feeding back ACK/nack message on PUCCH form 1a/1b channel on the corresponding channel of PUCCH form; When UE receives the data at least one SCC, feeding back ACK/nack message on PUCCH form 3 channels of the ARI indication in the PDCCH of SCC.
Embodiment two, when on the PDCCH of PCC and SCC, all sending ARI, the base station adopts identical method to handle to the PDCCH of PCC and SCC.As shown in Figure 7, mainly may further comprise the steps:
Step 701: base station dispatcher is UE allocation of downlink resource on a plurality of CC.
Here the base station downstream data channel that possibly only distribute PCC for UE, the downstream data channel of perhaps only having distributed SCC, perhaps the while has been distributed downstream data channel on PCC and SCC.
Step 702: according to the scheduling result of scheduler, the PDCCH that each CC of scheduling goes up data is sent in the base station.Wherein, in the PDCCH of the PDCCH of PCC and SCC, adopt RV information and the ARI information of mode transmission power control command provided by the invention, each TB respectively, for example the method shown in Fig. 4.
Step 703: the base station is according to the control information of indicating among current scheduling result and the PDCCH, on each CC, sends the downlink data of current scheduling for UE.
Step 704: the ACK/NACK information that receives the UE feedback on PUCCH form 3 channels of the ARI indication of base station in the PDCCH of PCC or SCC.
Corresponding with the operation of base station, when on the PDCCH of PCC and SCC, all sending ARI, UE adopts identical method to handle the PDCCH of PCC and SCC.As shown in Figure 8, mainly may further comprise the steps:
Step 801:UE receives the PDCCH (UE possibly only receive the PDCCH of PCC, perhaps only receives the PDCCH of SCC, perhaps receives the PDCCH of PCC and SCC simultaneously) that send the base station here.To each PDCCH, obtain transmission power control command, RV information and ARI information through demultiplexing TPC territory and RV territory; Perhaps from the TPC territory, obtain transmission power control command, two RV territories of demultiplexing obtain RV information and ARI information.
Step 802: the base station receives the downlink data that send the base station according to the control information among each PDCCH that receives on each CC, and generates the ACK/NACK feedback information.
Feeding back ACK/nack message on PUCCH form 3 channels of step 803:UE ARI indication in the PDCCH of PCC or SCC.
When UE receives the PDCCH of scheduling PCC simultaneously and dispatches the PDCCH of SCC; Because transmission power control command is 2 bits among the PDCCH of PCC; Information is more abundant, so UE can come feeding back ACK/nack message according to the transmission power control command among the PDCCH of PCC.
In Fig. 6 of the present invention and method shown in Figure 8, in the PDCCH that UE receives, possibly exist a part of PDCCH to comprise 2 bit transfer power control commands, and another part PDCCH comprise 1 bit transfer power control command.For example, transmission power control command is 2 bits among the PDCCH of PCC; In addition, according to the method for concrete employing, the PDCCH that SCC carries out the MIMO transfer of data possibly comprise 2 bit transfer power control commands, also possibly comprise 1 bit power control command; The PDCCH that SCC carries out the SIMO transmission possibly comprise 1 bit power control command.Because the information of dibit power power control command is more abundant; So when UE receives the PDCCH that comprises 2 bit transfer power control commands simultaneously and comprises the PDCCH of 1 bit transfer power control command, can come feeding back ACK/nack message according to the transmission power control command of 2 bits.
Can find out by above description; Through method provided by the invention; Be used to dispatch SIMO or be used to dispatch MIMO adopt different modes according to PDCCH; Through multiplexing TPC territory and RV territory, the mode in perhaps multiplexing two RV territories is sent ARI information, makes the transmission that when sending ARI information, can guarantee transmission power control command.Even if thereby only receive at UE under the situation of PDCCH of SCC, can guarantee still that through in the PDCCH of SCC, adopting aforesaid way UE obtains power control information, realize that up PUCCH form 3 channels send the correct transmission of ACK/NACK information.
The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being made, is equal to replacement, improvement etc., all should be included within the scope that the present invention protects.
