Definitions

  • the present disclosure relates to the field of communications technologies, and in particular, to a method, a receiving method, a terminal, and a base station for a physical uplink shared channel.
  • the terminal UE when the terminal UE has both Physical Shared Channel (PUSCH) and Uplink Control Information (UCI) transmission in a certain subframe, if the UE supports PUCCH (Physical Uplink Control Channel) and PUSCH are simultaneously transmitted, and UCI can be transmitted on the PUCCH to transmit data on the PUSCH. If the UE does not support simultaneous transmission of PUCCH and PUSCH, the UCI will be transmitted on the PUSCH along with the data.
  • the UCI includes at least a hybrid automatic repeat request acknowledgement (HARQ-ACK, Hybrid Automatic Repeat reQuest ACKnowlegement), channel state information (CSI, Channel State Information), and a scheduling request (SR, Scheduling Request).
  • HARQ-ACK Hybrid Automatic Repeat reQuest ACKnowlegement
  • CSI Channel State Information
  • SR Scheduling Request
  • the HARQ-ACK is transmitted on the PUSCH by puncturing the data on the PUSCH, that is, when the data on the PUSCH is subjected to channel coding and rate matching, whether or not there is HARQ-ACK, that is, according to no resources HARQ-ACK is occupied for channel coding and rate matching.
  • the HARQ-ACK is mapped to the corresponding resource for transmission according to a predetermined mapping rule.
  • the HARQ-ACK information will overwrite the data information on the resource, that is, the data information is punctured by the HARQ-ACK.
  • the method can ensure that the coding and rate matching of the data are not affected by the presence or absence of HARQ-ACK, thereby ensuring that the base station eNB and the UE have the same understanding of the code rate of the transmitted data. This is because, when the base station transmits the downlink data to the UE, according to the fixed HARQ-ACK feedback timing defined in the LTE, the base station expects the UE to feed back the HARQ-ACK of the downlink data at the corresponding feedback moment, but if If the terminal loses the downlink transmission, the terminal side does not perform the HARQ-ACK feedback of the downlink transmission. Therefore, the understanding of whether the base station and the terminal have the HARQ-ACK transmission in the corresponding feedback moment may be inconsistent.
  • the terminal When there is a PUSCH on the corresponding feedback moment and the terminal does not support PUCCH and PUSCH simultaneous transmission, since the HARQ-ACK is transmitted on the PUSCH by puncturing data information, even if the base station and the terminal have an understanding of whether or not there is HARQ-ACK transmission, the understanding is inconsistent. It also does not affect the process of decoding and de-rate matching of data transmitted by the base station to the terminal.
  • the 5G NR in addition to supporting fixed HARQ-ACK feedback timing (ie, when a downlink HARQ-ACK is forward-defined or configured), dynamic HARQ-ACK feedback timing is also supported. That is, the feedback of a downlink HARQ-ACK is indicated by the downlink control information (DCI, Downlink Control Information) corresponding to the downlink transmission.
  • DCI Downlink Control Information
  • the mini-slot based transmission is also supported in the 5G NR, that is, the transmission length of one downlink transmission may be shorter than one slot slot or the length of all downlink symbols in one slot, for example, 1.
  • the puncturing method is used for the transmission of the 1-2 bit HARQ-ACK on the PUSCH, and the rate matching is performed for the transmission of the HARQ-ACK greater than 2 bits on the PUSCH, that is, on the PUSCH.
  • the rate matching is performed for the transmission of the HARQ-ACK greater than 2 bits on the PUSCH, that is, on the PUSCH.
  • the HARQ-ACK is transmitted on the PUSCH by using the rate matching method.
  • the presence or absence of the HARQ-ACK and the number of bits of the HARQ-ACK may affect the coding and rate matching of the data on the PUSCH (ie, affecting the code rate of the data) and the actual mapped resource location. If the base station's perception of whether there is a HARQ-ACK and a HARQ-ACK bit number size is inconsistent with the actual transmission of the terminal, the base station will erroneously decode the PUSCH, resulting in failure of the PUSCH reception.
  • a downlink allocation index (DAI, Downlink Assignment Index) may be included in the uplink grant, which is used to indicate the number of bits of the HARQ-ACK transmitted on the PUSCH, and may be According to the information field and the number of actually received downlink transmissions, it is determined whether there is HARQ-ACK transmission.
  • DAI Downlink Assignment Index
  • the PUSCH transmission with no corresponding uplink grant is also supported, such as a semi-persistent scheduling (SPS) PUSCH and a grant-free PUSCH, that is, the base station does not send any scheduling information to the unscheduled PUSCH.
  • SPS semi-persistent scheduling
  • the RRC (Radio Resource Control) signaling configuration terminal can perform the location of the unscheduled PUSCH transmission and some configuration information, and the terminal performs the unscheduled PUSCH transmission according to the configuration information in the pre-configured location of the base station. It is also possible to support a PUSCH with a corresponding UL grant but no DAI in the UL grant.
  • the HARQ-ACK needs to be carried on the PUSCH for transmission. If the base station sends a downlink transmission to the terminal, but the terminal does not receive any downlink transmission, the terminal transmits data only on the PUSCH without carrying the HARQ-ACK, that is, the rate matching of the data on the PUSCH is performed according to the absence of the HARQ-ACK, but the base station does not If it is not determined that the terminal does not receive any downlink transmission, the HARQ-ACK and the PUSCH are still detected according to the rate matching manner in the case of the presence of the HARQ-ACK on the PUSCH, and thus the understanding of the resources occupied by the data is inconsistent with the actual transmission of the terminal, and thus the data is An error occurs in decoding, which causes the base station side to receive errors.
  • the terminal and the base station may have inconsistent understanding of whether the HARQ-ACK exists on the PUSCH, and the resources actually applied to the data transmission on the PUSCH. If the judgments of the location and the size are inconsistent, resulting in inconsistent rate matching results of the data, the base station will fail to receive the PUSCH transmission.
  • An object of the present invention is to provide a method for transmitting a physical uplink shared channel, a receiving method, a terminal, and a base station, to solve the problem that the base station and the base station have different understandings of whether the HARQ-ACK exists on the PUSCH in the prior art.

物理上行共享信道的传输方法、接收方法、终端及基站
相关申请的交叉引用
本申请主张在2017年12月8日在中国提交的中国专利申请号No.201711298155.8的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，特别是指一种物理上行共享信道的传输方法、接收方法、终端及基站。
背景技术
在LTE(长期研究)无线通信系统中，当终端UE在某个子帧中同时存在物理共享信道(PUSCH，Physical Uplink Shared Channel)和上行控制信息(UCI，Uplink Control Information)传输时，如果UE支持PUCCH(Physical Uplink Control Channel，物理上行链路控制信道)和PUSCH同时传输，则可以在PUCCH上传输UCI，在PUSCH上传输数据。如果UE不支持PUCCH和PUSCH同时传输，则UCI将与数据一同在PUSCH上传输。UCI至少包括混合自动重传请求确认(HARQ-ACK，Hybrid Automatic Repeat reQuest ACKnowlegement)、信道状态信息(CSI,Channel State Information)、调度请求(SR，Scheduling Request)。
在LTE系统中，HARQ-ACK在PUSCH上通过对PUSCH上的数据进行打孔来传输，即PUSCH上的数据在进行信道编码和速率匹配时，不考虑是否存在HARQ-ACK，即按照没有资源被HARQ-ACK占用来进行信道编码和速率匹配。当存在HARQ-ACK时，HARQ-ACK按照预定的映射规则，映射到对应的资源上进行传输，此时HARQ-ACK信息将覆盖该资源上的数据信息，即数据信息被HARQ-ACK打孔。该方法可以保证数据的编码和速率匹配不受是否存在HARQ-ACK的影响，从而保证基站eNB和UE对传输数据的码率的理解一致。这是因为，当基站向UE发送了下行数据时，根据LTE中定义的固定的HARQ-ACK反馈时序(timing)，基站则期望UE在对应的 反馈时刻反馈该下行数据的HARQ-ACK，但如果终端丢失了下行传输，则终端侧并没有进行下行传输的HARQ-ACK反馈，因此基站和终端对在对应反馈时刻中是否存在HARQ-ACK传输的理解可能是不一致。当对应的反馈时刻上存在PUSCH且终端不支持PUCCH和PUSCH同时传输，由于HARQ-ACK是通过打孔数据信息的方式在PUSCH上传输，即使基站和终端对是否存在HARQ-ACK传输的理解是不一致，也不会影响基站对终端所传输的数据的解码和解速率匹配的过程。
在5G NR(5G新空口)中，除了支持固定的HARQ-ACK反馈timing(即一个下行传输的HARQ-ACK在哪个时刻反馈是预先定义或配置的)，还支持动态的HARQ-ACK反馈timing，即一个下行传输的HARQ-ACK在哪个时刻反馈是可以通过下行传输对应的下行控制信息(DCI，Downlink Control Information)指示的。此外，5G NR中还支持基于微时隙(mini-slot)的传输，即一次下行传输的传输长度可能为短于1个时隙slot或者一个时隙中的所有下行符号的长度，例如1、2、4、7等任意符号长度的传输，还支持基于码块组(CBG，Code Block Group)的HARQ-ACK反馈，以及多载波传输等，这些因素都会导致HARQ-ACK反馈比特数较LTE增加很多，如果仍然使用对PUSCH上数据进行打孔的方式在PUSCH上传输HARQ-ACK，将会导致PUSCH的很多数据信息都被HARQ-ACK打孔，对PUSCH的传输性能影响较大。
因此，5G NR中对于1～2比特的HARQ-ACK在PUSCH上的传输使用打孔的方式，对于大于2比特的HARQ-ACK在PUSCH上的传输使用速率匹配的方式，即在对PUSCH上的数据进行编码和速率匹配的时候去掉被HARQ-ACK所占用的资源。
采用速率匹配方式在PUSCH上传输HARQ-ACK，是否存在HARQ-ACK以及HARQ-ACK的比特数会影响数据在PUSCH上的编码和速率匹配(即影响数据的码率)以及实际映射资源位置。如果基站对是否存在HARQ-ACK以及HARQ-ACK的比特数大小的认知与终端的实际传输不一致，将导致基站对PUSCH的错误译码，导致PUSCH接收失败。在5G NR中，对于有上行许可(UL grant)的PUSCH，在上行许可中可以包含下行分配索引(DAI， Downlink Assignment Index)，用于指示在PUSCH上传输的HARQ-ACK的比特数，并且可以根据该信息域与实际接收到的下行传输的个数综合判断是否存在HARQ-ACK传输。
在5G NR中，还支持对没有对应的上行许可的PUSCH传输，如半持续调度(SPS，Semi-Persistent Scheduling)PUSCH、免调度(grant-free)PUSCH，即基站不对免调度PUSCH发送任何调度信息，仅通过RRC(Radio Resource Control，无线资源控制)信令配置终端可以进行免调度PUSCH传输的位置和一些配置信息，终端在基站预先配置的位置中根据配置信息进行免调度PUSCH传输。还可能支持有对应的UL grant但UL grant中没有DAI的PUSCH。
当HARQ-ACK和上述PUSCH在同一时刻发生且不支持PUCCH和PUSCH同时传输时，HARQ-ACK需要承载在PUSCH上传输。如果基站向终端发送了下行传输，但终端没有接收到任何下行传输，则终端仅在PUSCH上传输数据而不携带HARQ-ACK，即PUSCH上数据的速率匹配按照没有HARQ-ACK进行，但基站并不能判断终端没有接收到任何下行传输，则仍然按照PUSCH上存在HARQ-ACK情况下的速率匹配方式去检测HARQ-ACK和PUSCH，因而对数据占用的资源的理解和终端实际发送不一致，因而数据的译码会发生错误，会导致基站侧接收错误。
综上，在5G NR中，当HARQ-ACK在PUSCH上的传输使用速率匹配方式时，终端和基站可能对PUSCH上是否存在HARQ-ACK的理解不一致，则在PUSCH上实际应用于数据传输的资源位置和大小的判断不一致，从而导致数据的速率匹配结果不一致，则将导致基站对PUSCH传输的接收失败。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
如图1所示，本公开实施例提供一种物理上行共享信道PUSCH的传输方法，包括：
步骤11，确定混合自动重传请求确认的指示信息；其中，所述混合自动重传请求确认的指示信息至少用于指示目标PUSCH上是否存在混合自动重传请求确认信息；
步骤12，在所述目标PUSCH上传输所述指示信息。
本公开的上述实施例中，终端可基于是否接收到基站在物理下行共享信道PDSCH上传输的传输块TB或码块组CBG或是否接收到指示下行SPS资源释放的PDCCH，来确定指示信息的内容。需要说明的是，在一个上行传输时刻传输的一个目标PUSCH，其上的指示信息可以是针对一个PDSCH或指示下行SPS资源释放的PDCCH的HARQ-ACK的指示信息，也可以是针对多个PDSCH和/或指示下行SPS资源释放的PDCCH的HARQ-ACK的指示信息，具体根据HARQ-ACK反馈时序确定在当前上行传输时刻所对应的下行传输的范围，在此不作具体限定。
较佳的，所述指示信息的比特数为1比特时，所述1比特的指示信息的指示状态为“0”时，所述指示信息用于指示所述目标PUSCH上存在混合自动重传请求确认信息；所述1比特的指示信息的指示状态为“1”时，所述指示信息用于指示所述目标PUSCH上不存在混合自动重传请求确认信息；或者，所述1比特的指示信息的指示状态为“1”时，所述指示信息用于指示所述目标PUSCH上存在混合自动重传请求确认信息；所述1比特的指示信息的指示状态为“0”时，所述指示信息用于指示所述目标PUSCH上不存在混合自动重传请求确认信息。
或者，所述指示信息包含第一指示域和第二指示域；其中，所述第一指示域用于指示目标PUSCH上是否存在混合自动重传请求确认信息，所述第二指示域用于指示所述混合自动重传请求确认信息的比特数；其中，所述第一指示域和所述第二指示域独立编码或者联合编码。
具体的，第一指示域的比特数可以为1比特；例如，1比特的第一指示 域为“0”时，所述第一指示域用于指示所述目标PUSCH上存在混合自动重传请求确认信息；所述1比特的第一指示域为“1”时，所述第一指示域用于指示所述目标PUSCH上不存在混合自动重传请求确认信息；或者，所述1比特的第一指示域为“1”时，所述第一指示域用于指示所述目标PUSCH上存在混合自动重传请求确认信息；所述1比特的第一指示域为“0”时，所述第一指示域用于指示所述目标PUSCH上不存在混合自动重传请求确认信息。
而第二指示域的比特数可以大于1比特。例如第二指示域的比特数为2比特，则第二指示域可以指示4个状态，每个状态对应一个混合自动重传请求确认信息的比特数；或者，第二指示域也可以通过多对一的方式用4个状态指示超过4个混合自动重传请求确认信息的比特数。例如，2比特的第二指示域为“00”则可以表示1/5/9等比特数，2比特的第二指示域为“01”可以表示2/6/10等比特数，2比特的第二指示域为“10”可以表示3/7/11等比特数，2比特的第二指示域为“11”可以表示4/8/12等比特数。同一个状态对应的不同比特数可以结合实际的下行接收数据包(PDSCH和指示下行SPS资源释放的PDCCH)个数来确定对应的值；在此不作具体限定。
具体的，所述第一指示域和所述第二指示域独立编码或者联合编码；如果是独立编码，则指示信息中是否存在第二指示域可以根据第一指示域的指示内容确定；例如当第一指示域指示目标PUSCH上不存在混合自动重传请求确认信息时，则可以确定不存在第二指示域；而当第一指示域指示目标PUSCH上存在混合自动重传请求确认信息时，则可以确定存在第二指示域。如果为联合编码，则第一指示域和第二指示域总是同时存在。
或者，所述指示信息的比特数为M比特；
其中，所述M比特的指示信息的一种指示状态用于指示目标PUSCH上不存在混合自动重传请求确认信息；所述M比特指示信息的其余指示状态用于指示所述混合自动重传请求确认信息的比特数；其中，M为大于1的整数。
例如，M＝2时，则该指示信息可以包含4种指示状态；例如指示状态“00”表示目标PUSCH上不存在混合自动重传请求确认信息，也即表示混合自动重传请求确认信息的比特数为0；指示状态“01”可以表示1/4/7等比特数，指示状态“10”可以表示2/5/8等比特数，指示状态“11”可以表示3/6/9等 比特数。同一个指示状态对应的不同比特数可以结合实际的下行接收数据包个数来确定对应的值；当然M也可以是3比特，则8种指示状态中的一个指示状态用于指示目标PUSCH上不存在混合自动重传请求确认信息，而剩余的7种指示状态可以指示7种不同比特数或7种不同比特数集合。
较佳的，本公开的上述实施例中步骤12包括：
采用速率匹配方式在所述目标PUSCH上传输所述指示信息。
具体的，所述采用速率匹配方式在所述目标PUSCH上传输所述指示信息的步骤，包括：
确定在所述目标PUSCH中传输的数据不映射到所述指示信息在所述目标PUSCH上占用的资源上。
具体的，本公开的上述实施例中步骤12包括：
确定所述指示信息在所述目标PUSCH上占用的第一传输资源；
将所述指示信息依次进行信道编码、速率匹配以及调制后映射到所述目标PUSCH的第一传输资源上进行传输。
需要说明的是，指示信息的信道编码方式包括：重复编码、使用占位符的编码、瑞德穆勒RM编码、TBCC(Tail Biting Convolutional Coding，咬尾卷积码)、极化码Polar、LDPC(Low Density Parity Check Code，低密度奇偶校验码)等编码方式中的任意一种编码方式或者任意多种的组合编码方式。
进一步的，所述确定所述指示信息在所述目标PUSCH上占用的第一传输资源的步骤，包括：
获取预先预定或者预先配置的所述目标PUSCH上的第一传输资源的资源位置和资源大小；或者，获取预先预定或者预先配置的所述目标PUSCH上的第一传输资源的资源位置，并根据预先配置的配置参数以及所述目标PUSCH的传输参数确定所述目标PUSCH上的第一传输资源的资源大小；
根据所述第一传输资源的资源位置和资源大小，确定所述第一传输资源。
第一传输资源的资源位置可以是预先约定的，也可以是预先配置的。例如，第一传输资源的资源位置为：PUSCH的第一符号或前A个符号上的预定频域资源上；或者，PUSCH的解调参考信号DMRS一侧或两侧的符号上的预定频域资源上，或者，离散分布在PUSCH所占用的多个符号中的预定 频域资源上。其中，所述预定频域资源为PUSCH频域资源的高频或低频端的B个RE(资源粒子)，或离散分布在PUSCH频域资源上的B个RE，或均匀分布在高频和低频两端的B个RE。
第一传输资源的资源大小可以为预先预定或预先配置的，也可以为终端根据配置参数以及PUSCH的传输参数确定。例如，高层信令预先配置一个用于确定指示信息的资源偏移值参数，根据该资源偏移值参数以及PUSCH的传输参数(如调制编码等级、资源大小等)，确定指示信息在PUSCH上的第一传输资源的资源大小。
进一步的，本公开的上述实施例中，为了避免目标PUSCH上传输的不同信息产权混淆，步骤12还包括：
对所述指示信息和在所述目标PUSCH中传输的数据进行独立的信道编码。
和/或，若所述指示信息指示所述目标PUSCH上存在混合自动重传请求确认信息，对所述指示信息和所述混合自动重传请求确认信息进行独立的信道编码。
进一步的，本公开上述实施例中，步骤12还包括：
确定所述指示信息的调制方式；
其中，所述指示信息的调制方式与所述目标PUSCH的调制方式相同；或者根据预先定义或预先配置确定所述指示信息的调制方式为基于二进制相移键控BPSK的调制方式或者基于正交相移键控QPSK的调制方式或者基于正交幅度调制16QAM的调制方式。
需要说明的是，指示信息的调制方式基站侧也能够基于与终端侧相同的方式确定，从而使得基站可以利用与指示信息的调制方法对应的解调方式对指示信息进行解调，从而正确接收指示信息。
一种实施方式中，所述目标PUSCH为以下任意一种：没有对应的上行许可的PUSCH、没有对应的下行分配索引的PUSCH。
另一种实施方式中，所述目标PUSCH为以下任意一种：半持续调度的PUSCH、免调度的PUSCH、有对应的上行许可但上行许可中不包含下行分配索引的PUSCH。

其中预设条件包括：
条件1：在所述目标PUSCH上传输的混合自动重传请求确认信息的比特数大于预定比特数；
条件2：在所述目标PUSCH上采用速率匹配方式传输混合自动重传请求确认信息；
条件3：传输所述目标PUSCH的终端不支持同时传输物理上行链路控制信道PUCCH和PUSCH。
综上，本公开的上述实施例中终端在PUSCH上额外传输混合自动重传请求确认HARQ-ACK的指示信息，该指示信息至少用于指示目标PUSCH上是否存在混合自动重传请求确认信息，从而使得基站能够根据PUSCH上传输的指示信息确定PUSCH上是否存在HARQ-ACK信息，从而保证终端和基站对PUSCH上的数据传输占用的资源理解一致，从而进一步保证基站能够正确接收PUSCH上传输的数据，提高传输性能。
如图2所示，本公开实施例还提供一种物理上行共享信道PUSCH的接收方法，包括：
步骤21，在目标PUSCH上接收混合自动重传请求确认的指示信息；其中，所述混合自动重传请求确认的指示信息至少用于指示所述目标PUSCH上是否存在混合自动重传请求确认信息；
步骤22，根据所述指示信息，确定所述目标PUSCH上是否存在混合自动重传请求确认信息。
较佳的，所述指示信息的比特数为1比特时，所述1比特的指示信息的指示状态为“0”时，所述指示信息用于指示所述目标PUSCH上存在混合自动重传请求确认信息；所述1比特的指示信息的指示状态为“1”时，所述指示信息用于指示所述目标PUSCH上不存在混合自动重传请求确认信息；或者，所述1比特的指示信息的指示状态为“1”时，所述指示信息用于指示所述目标PUSCH上存在混合自动重传请求确认信息；所述1比特的指示信息 的指示状态为“0”时，所述指示信息用于指示所述目标PUSCH上不存在混合自动重传请求确认信息。
或者，所述指示信息包含第一指示域和第二指示域；其中，所述第一指示域用于指示目标PUSCH上是否存在混合自动重传请求确认信息，所述第二指示域用于指示所述混合自动重传请求确认信息的比特数；其中，所述第一指示域和所述第二指示域独立编码或者联合编码。
具体的，第一指示域的比特数可以为1比特；例如，1比特的第一指示域为“0”时，所述第一指示域用于指示所述目标PUSCH上存在混合自动重传请求确认信息；所述1比特的第一指示域为“1”时，所述第一指示域用于指示所述目标PUSCH上不存在混合自动重传请求确认信息；或者，所述1比特的第一指示域为“1”时，所述第一指示域用于指示所述目标PUSCH上存在混合自动重传请求确认信息；所述1比特的第一指示域为“0”时，所述第一指示域用于指示所述目标PUSCH上不存在混合自动重传请求确认信息。
而第二指示域的比特数可以大于1比特。例如第二指示域的比特数为2比特，则第二指示域可以指示4个状态，每个状态对应一个混合自动重传请求确认信息的比特数；或者，第二指示域也可以通过多对一的方式用4个状态指示超过4个混合自动重传请求确认信息的比特数。例如，2比特的第二指示域为“00”则可以表示1/5/9等比特数，2比特的第二指示域为“01”可以表示2/6/10等比特数，2比特的第二指示域为“10”可以表示3/7/11等比特数，2比特的第二指示域为“11”可以表示4/8/12等比特数。同一个状态对应的不同比特数可以结合实际的下行接收数据包(PDSCH和指示下行SPS资源释放的PDCCH)个数来确定对应的值；在此不作具体限定。
具体的，所述第一指示域和所述第二指示域独立编码或者联合编码；如果是独立编码，则指示信息中是否存在第二指示域可以根据第一指示域的指示内容确定；例如当第一指示域指示目标PUSCH上不存在混合自动重传请求确认信息时，则可以确定不存在第二指示域；而当第一指示域指示目标PUSCH上存在混合自动重传请求确认信息时，则可以确定存在第二指示域。如果为联合编码，则第一指示域和第二指示域总是同时存在。
或者，所述指示信息的比特数为M比特；
其中，所述M比特的指示信息的一种指示状态用于指示目标PUSCH上不存在混合自动重传请求确认信息；所述M比特指示信息的其余指示状态用于指示所述混合自动重传请求确认信息的比特数；其中，M为大于1的整数。
例如，M＝2时，则该指示信息可以包含4种指示状态；例如指示状态“00”表示目标PUSCH上不存在混合自动重传请求确认信息，也即表示混合自动重传请求确认信息的比特数为0；指示状态“01”可以表示1/4/7等比特数，指示状态“10”可以表示2/5/8等比特数，指示状态“11”可以表示3/6/9等比特数。同一个指示状态对应的不同比特数可以结合实际的下行接收数据包个数来确定对应的值；当然M也可以是3比特，则8种指示状态中的一个指示状态用于指示目标PUSCH上不存在混合自动重传请求确认信息，而剩余的7种指示状态可以指示7种不同比特数或7种不同比特数集合。
较佳的，本公开的上述实施例中步骤21包括：
采用速率匹配方式在所述目标PUSCH上接收所述指示信息。
较佳的，所述采用速率匹配方式在所述目标PUSCH上接收所述指示信息的步骤，包括：
确定在所述目标PUSCH中传输的数据不映射到所述指示信息在所述目标PUSCH上占用的资源上。
较佳的，本公开的上述实施例中步骤21包括：
确定所述指示信息在所述目标PUSCH上占用的第一传输资源；
在所述第一传输资源上接收所述混合自动重传请求确认的指示信息。
进一步的，所述确定所述指示信息在所述目标PUSCH上占用的第一传输资源的步骤，包括：
获取预先预定或者预先配置的所述目标PUSCH上的第一传输资源的资源位置和资源大小；或者获取预先预定或者预先配置的所述目标PUSCH上的第一传输资源的资源位置，并根据预先配置的配置参数以及所述目标PUSCH的传输参数确定所述目标PUSCH上的第一传输资源的资源大小；
根据所述第一传输资源的资源位置和资源大小，确定所述第一传输资源。
第一传输资源的资源位置可以是预先约定的，也可以是预先配置的。例如，第一传输资源的资源位置为：PUSCH的第一符号或前A个符号上的预 定频域资源上；或者，PUSCH的解调参考信号DMRS一侧或两侧的符号上的预定频域资源上，或者，离散分布在PUSCH所占用的多个符号中的预定频域资源上。其中，所述预定频域资源为PUSCH频域资源的高频或低频端的B个RE(资源粒子)，或离散分布在PUSCH频域资源上的B个RE，或均匀分布在高频和低频两端的B个RE。
第一传输资源的资源大小可以为预先预定或预先配置的，也可以为终端根据配置参数以及PUSCH的传输参数确定。例如，高层信令预先配置一个用于确定指示信息的资源偏移值参数，根据该资源偏移值参数以及PUSCH的传输参数(如调制编码等级、资源大小等)，确定指示信息在PUSCH上的第一传输资源的资源大小。
进一步的，本公开的上述实施例中，为了避免目标PUSCH上传输的不同信息产权混淆，步骤21包括：
确定所述指示信息和在所述目标PUSCH中传输的数据采用独立的信道编码。
和/或，若所述指示信息指示所述目标PUSCH上存在混合自动重传请求确认信息，确定所述指示信息和所述混合自动重传请求确认信息采用独立的信道编码。
进一步的，本公开的上述实施例中步骤21还包括：
确定所述指示信息的调制方式；
其中，所述指示信息的调制方式与所述目标PUSCH的调制方式相同；或者根据预先定义或预先配置确定所述指示信息的调制方式为基于二进制相移键控BPSK的调制方式或者基于正交相移键控QPSK的调制方式或者基于正交幅度调制16QAM的调制方式。
需要说明的是，指示信息的调制方式基站侧也能够基于与终端侧相同的方式确定，从而使得基站可以利用与指示信息的调制方法对应的解调方式对指示信息进行解调，从而正确接收指示信息。
较佳的，本公开的上述实施例中所述目标PUSCH为以下任意一种：没有对应的上行许可的PUSCH、没有对应的下行分配索引的PUSCH；或者，
所述目标PUSCH为以下任意一种：半持续调度的PUSCH、免调度的 PUSCH、有对应的上行许可但上行许可中不包含下行分配索引的PUSCH。
进一步的，本公开的上述实施例中步骤21之前，其接收方法还包括：判断是否满足预设条件中的至少一个，当满足预设条件中的至少一个时，进行步骤21，否则可以不进行步骤21和22：
其中预设条件包括：
条件1：在所述目标PUSCH上传输的混合自动重传请求确认信息的比特数大于预定比特数；
条件2：在所述目标PUSCH上采用速率匹配方式传输混合自动重传请求确认信息；
条件3：传输所述目标PUSCH的终端不支持同时传输物理上行链路控制信道PUCCH和PUSCH。
综上，本公开的上述实施例中终端在PUSCH上额外传输混合自动重传请求确认HARQ-ACK的指示信息，该指示信息至少用于指示目标PUSCH上是否存在混合自动重传请求确认信息，从而使得基站能够根据PUSCH上传输的指示信息确定PUSCH上是否存在HARQ-ACK信息，从而保证终端和基站对PUSCH上的数据传输占用的资源理解一致，从而进一步保证基站能够正确接收PUSCH上传输的数据，提高传输性能。
为了更清楚的描述本公开实施例提供的PUSCH的传输及接收方法，下面结合一具体实施例对本公开实施例提供的PUSCH的传输及接收方法进行说明：
假设2个物理下行共享信道PDSCH的混合自动重传请求确认信息(HARQ-ACK信息)都在同一上行时刻(例如目标PUSCH)进行反馈；该上行时刻可以是每个PDSCH对应的物理下行控制信道PDCCH的第一指示域通知的，也可以是根据预先定义或者配置的反馈时序确定的，在此不作具体限定。例如，如图3所示，时隙n、时隙n+1、时隙n+2、时隙n+3以及时隙n+4为下行时隙，时隙n+5、时隙n+6、时隙n+7、时隙n+8以及时隙n+9为上行时隙；其中，基站在时隙n和时隙n+1依次传输上述两个PDSCH，且在时隙n和时隙n+1上传输的两个PDSCH都在时隙n+5上反馈HARQ-ACK信息；其中，时隙n+5为免调度的PUSCH的时隙。
假设每个PDSCH对应4比特HARQ-ACK信息(例如每个PDSCH包含1个传输块TB，每个TB被配置为基于码块组CBG的HARQ-ACK且每个TB包含4个CBG)；则在该上行时刻中共计8比特的HARQ-ACK信息；HARQ-ACK信息的比特数可以是PDSCH对应的PDCCH中的第二指示域通知的，也可以是预先约定或预先配置确定的固定值。
假设该上行时刻为配置给免调度grant-free的PUSCH的时刻(即目标PUSCH为免调度的PUSCH)，且终端不支持PUCCH和PUSCH同时传输。则此时PUSCH的传输和接收存在两种情况，分别为情况1和情况2。
具体的，情况1的终端侧的行为如下：
当终端接收到上述两个PDSCH中的至少一个PDSCH时，终端确定该上行时刻的免调度PUSCH上存在HARQ-ACK信息，将1比特的HARQ-ACK的指示信息设置为“0”(假设预先约定“0”表示PUSCH上存在HARQ-ACK信息)。
终端对指示信息进行信道编码及速率匹配得到目标编码比特数；例如，采用占位符编码方式，如表1所示，针对不同的调制方式Qm，进行初始占位编码，初始占位编码之后的编码信息再经过重复编码得到目标编码比特数；或者，也可以直接使用RM或polar编码以及速率匹配将其编码到目标编码比特数。其中，目标编码比特数是根据指示信息在目标PUSCH上占用的资源大小以及使用的调制方式确定的。例如：高层信令配置或者根据高层配置的资源参数以及PUSCH的传输参数确定指示信息占用10个RE(Resource Element，资源粒子)，使用BSPK调制方式(Qm＝1)，则目标编码比特数为10比特；又例如指示信息占用10个RE，使用QPSK调制方式(Qm＝2)，则目标编码比特数为20比特。将指示信息的编码后的信息经过调制得到该指示信息的调制符号，将该调制符号映射到目标PUSCH上的对应资源(该对应资源具体指指示信息在目标PUSCH上占用的第一传输资源)上传输。
Figure PCTCN2018112929-appb-000001
表1HARQ-ACK信息的占位符编码
终端对每个PDSCH的每个CBG产生1比特的HARQ-ACK信息，共计得到8比特的HARQ-ACK信息。如果终端只接收到一个PDSCH，终端可以通过HARQ-ACK的码本(codebook)类型(半静态或动态)确定总反馈比特数为8比特。按照HARQ-ACK信息在目标PUSCH上的传输资源大小以及HARQ-ACK的调制方式，将8比特HARQ-ACK信息进行编码(速率匹配)和调制后，映射到该目标PUSCH上的对应资源(该对应资源具体指HARQ-ACK信息在目标PUSCH上占用的第二传输资源)上传输。
终端将该目标PUSCH所占用的资源中除去上述指示信息占用的第一传输资源和HARQ-ACK信息占用的第二传输资源以外的资源作为数据传输资源，对待传输的数据进行编码、速率匹配以及调制后，映射到对应的数据传输资源上进行传输。
相应的，情况1的基站侧的行为如下：
基站按照上述终端侧相同的方式确定指示信息在目标PUSCH上占用的第一传输资源，在对应的第一传输资源上接收该指示信息，并译码得到原始的1比特指示信息，根据1比特的指示信息为“0”确定目标PUSCH上存在HARQ-ACK信息。
进一步，基站按照终端侧相同的方式确定HARQ-ACK信息在目标PUSCH上占用的第二传输资源，基站在对应的第二传输资源上接收HARQ-ACK信息，并译码得到原始的8比特的HARQ-ACK信息，进一步根据该HARQ-ACK信息确定如何对PDSCH的CBG进行重传。
进一步，基站按照终端侧相同的方式确定目标PUSCH所占用的资源中除去上述指示信息占用的第一传输资源和HARQ-ACK信息占用的第二传输资源以外的资源为数据传输资源，基站在对应的数据传输资源上接收数据，并译码得到PUSCH上传输的数据信息，例如传输块TB。
承接上例，情况2的终端侧情况如下：
当终端没有接收到上述两个PDSCH(即上述两个PDSCH均丢包)，终端确定该上行时刻的免调度PUSCH上不存在HARQ-ACK信息，将1比特的HARQ-ACK的指示信息设置为“1”(假设预先约定“1”表示PUSCH上不存在HARQ-ACK信息)。
终端对指示信息进行信道编码及速率匹配得到目标编码比特数；例如，采用占位符编码方式，针对不同的调制方式Qm，进行初始占位编码，初始占位编码之后的编码信息再经过重复编码得到目标编码比特数；或者，也可以直接使用RM或polar编码以及速率匹配将其编码到目标编码比特数。其中，目标编码比特数是根据指示信息在目标PUSCH上占用的资源大小以及使用的调制方式确定的。例如：高层信令配置或者根据高层配置的资源参数以及PUSCH的传输参数确定指示信息占用10个RE(Resource Element，资源粒子)，使用BSPK调制方式(Qm＝1)，则目标编码比特数为10比特；又例如指示信息占用10个RE，使用QPSK调制方式(Qm＝2)，则目标编码比特数为20比特。将指示信息的编码后的信息经过调制得到该指示信息的调制符号，将该调制符号映射到目标PUSCH上的对应资源(该对应资源具体指指示信息在目标PUSCH上占用的第一传输资源)上传输。终端对指示信息进行信道编码、速率匹配、调制和映射传输的方式与上述情况1下终端侧的行为相同。
终端将该目标PUSCH所占用的资源中除去上述指示信息占用的第一传输资源以外的资源作为数据传输资源，对待传输的数据进行编码、速率匹配以及调制后，映射到对应的数据传输资源上进行传输。
相应的，情况2的基站侧的行为如下：
基站按照上述终端侧相同的方式确定指示信息在目标PUSCH上占用的第一传输资源，在对应的第一传输资源上接收该指示信息，并译码得到原始的1比特指示信息，根据1比特的指示信息为“1”确定目标PUSCH上不存在HARQ-ACK信息。进一步的，如果基站实际向终端调度了PDSCH，则基站可进一步判断终端对调度的PDSCH丢包，则基站可以重传对应的PDSCH。
进一步，基站按照终端侧相同的方式确定目标PUSCH所占用的资源中除去上述指示信息占用的第一传输资源以外的资源为数据传输资源，基站在对应的数据传输资源上接收数据，并译码得到PUSCH上传输的数据信息，例如传输块TB。
本公开实施例的上述情况2中，虽然终端丢失PDSCH，但是由于PUSCH上存在指示信息，基站可以通过该指示信息确定PUSCH上是否存在 HARQ-ACK，从而正确判断PUSCH上的数据传输占用的资源，从而达到对数据的正确译码。
需要说明的是，上述具体实施例中以免调度的PUSCH为例，如果替换为没有上行许可的PUSCH或者没有下行分配索引的PUSCH或者半持续调度的PUSCH或者有上行许可但所述上行许可不包含下行分配索引的PUSCH，本公开实施例提供的传输方法和接收方法均适用。当然，本公开也可以应用于其他任何一种PUSCH，例如有对应的上行许可且上行许可中存在下行分配索引DAI的PUSCH，在此不一一枚举。上述具体实施例中以需要进行HARQ-ACK反馈的下行传输为PDSCH为例，如果替换为指示下行SPS资源释放的PDCCH同样适用。
进一步需要说明的是，上述具体实施例中仅以使用基于CBG的HARQ-ACK反馈为例，在不使用基于CBG的HARQ-ACK反馈的情况下多个PDSCH和/或指示下行SPS资源释放的PDCCH的HARQ-ACK在同一上行时刻进行反馈时同样适用。且上述实施例仅以单载波为例，当然在多个载波聚合时，多个载波的一个或多个下行传输在同一个上行传输时刻进行HARQ-ACK反馈时同样适用。
