Description

确定信道的方法和装置 技术领域
本申请涉及通信领域，并且更具体地，涉及一种确定信道的方法和装置。
背景技术
在第五代(5th generation，5G)移动通信系统中，上行链路以及侧行链路的发送受用户设备(user equipment，UE)的能力，发送功率以及信道环境的限制，在同一时刻并不能同时发送多个信道或参考信号，比如物理上行控制信道(physical uplink control channel，PUCCH)与物理上行共享信道(physical uplink share channel，PUSCH)，物理侧行控制信道(physical sidelink control channel,PSCCH)，物理侧行反馈信道(physical sidelink feedback channel,PSFCH)和物理侧行数据信道(physical sidelink share channel,PSSCH)，且无论不同的信道是在同一载波还是不同载波上都可能会受到限制，从而不能同时发送。
为了避免同时发送，一方面要求基站在调度时就尽量避免不同信道之间的冲突，另一方面在无法避免冲突时定义相应的规则，确定需要发送哪一个信道，从而使基站和UE之间达成一致。但是在多个信道同时与相同的一个信道冲突时保持基站和UE之间能够在确定资源的过程中保持一致，以进一步满足终端设备的发送需要，从而提高上行或者侧行传输的可靠性，是当前需要解决的问题。
发明内容
本申请提供一种信道确定的方法和装置，能够为基站和终端设备确定用于传输的信道，提高传输的可靠性。

为便于理解本申请实施例，下面先对本申请涉及到的几个概念进行简单介绍。
1、时隙(time slot)和时域符号
时隙可以理解为专用于某一个单个通道的时隙信息的串行自复用的一个部分。时隙可以理解为一个通道。
在本申请的实施例中，符号也称为时域符号，可以是正交频分复用(orthogonal  frequency division multiplexing，OFDM)符号，也可以是单载波频分多址(single carrier frequency division multiple access，SC-FDMA)符号，其中SC-FDMA又称为带有转换预编码的正交频分复用(orthogonal frequency division multiplexing with transform precoding，OFDM with TP)。
此外，时域符号也可以理解为时间单元，例如，1个时间单元可以是一个或多个子帧；或者，也可以是一个或多个时隙；或者，也可以是一个或多个符号。当1个时间单元就是一个符号的时候，本申请实施例的描述中，时域符号和时间单元可以是等效的。
2、物理上行信道
可用于承载上行控制信息和/或上行数据的信道。例如，该物理上行信道可以包括LTE协议或NR协议中定义的物理上行控制信道(physical uplink control channel，PUCCH)、物理上行共享信道(physical uplink share channel，PUSCH)以及随着网络演变而定义的具有上述功能的其他上行信道。
3、下行控制信息(download control information，DCI)
主要用于发送下行调度分配信息，有多种不同的格式，包括但不限于DCI format 0-0，0-1，1-0，1-1，2-0，2-1，2-2，2-3。
4、PUCCH资源指示字段或者PUCCH资源指示域(PUCCH resource indicator field)
DCI中的M比特(bit)的信息字段，用于指示HARQ-ACK信息可用的传输资源，可选的，所述M等于3。
下面，对本申请实施例的传输对象上行控制信息(uplink control information，UCI)进行详细说明。
在本申请实施例中，上行控制信息UCI包含有混合自动重传请求应答消息(hybrid automatic repeat request acknowledgement，HARQ-ACK)，调度请求(scheduling request，SR)，CSI(CQI，PMI，RI)中的至少一项。
4、物理侧行控制信道(physical sidelink control channel,PSCCH)
PSCCH可用于承载侧行控制信息和/或侧行反馈控制信息等。5、物理侧行数据共享信道(physical sidelink share channel,PSSCH)
PSSCH可以用于发送侧行数据等。
6、物理侧行反馈信道(physical sidelink feedback channel,PSFCH)
PSFCH可以用于承载侧行反馈控制信息，例如用于反馈侧行数据的HARQ信息。
作为示例而非限定，在本申请实施例中上行控制信息可以包括但不限于以下一种或多种信息：
1.反馈信息
在本申请实施例中，该上行控制信息可以包括针对下行数据的反馈信息。
具体的说，在本申请实施例中，下行数据的传输可以采用反馈技术，作为示例而非限定，该反馈技术可以包括例如，混合自动重传请求(hybrid automatic repeat request，HARQ)技术。
其中，HARQ技术是一种将前向纠错编码(forward error correction，FEC)和自动重传请求(automatic repeat request，ARQ)相结合而形成的技术。
例如，在HARQ技术中，接收端在从发送端接收到数据后，可以确定该数据是否准 确译码。如果不能准确译码，则接收端可以向发送端反馈非确认(negative-acknowledge，NACK)信息，从而，发送端可以基于NACK信息，确定接收端没有准确接收到数据，从而可以进行重传处理；如果能够准确译码，则接收端可以向发送端反馈确认(acknowledge，ACK)信息，从而，发送端可以基于ACK信息，确定接收端准确接收到数据，从而可以确定完成了数据传输。
即，在本申请实施例中，当接收端解码成功时可以向发送端ACK信息，在解码失败时可以向发送端反馈NACK信息
作为示例而非限定，在本申请实施例中，上行控制信息可以包括HARQ技术中的ACK信息或NACK信息。其中，HARQ-ACK用于反馈下行数据信道PDSCH的接收情况，当UE接收正确，会发送ACK。当UE接收错误，会发送NACK。基站根据UE对PDSCH信道的反馈信息，来确定接下来的调度策略，比如是重传还是新传。
作为示例而非限定，在本申请实施例中，侧行反馈控制信息可以包括HARQ技术中的ACK信息或NACK信息。其中，HARQ-ACK用于反馈侧行数据信道PSSCH的接收情况，当发送UE向接收UE发送PSSCH，接收UE正确接收PSSCH，会发送ACK。当接收UE接收错误，会发送NACK。基站或发送UE或第三UE根据接收UE对PSSCH的反馈信息，来确定接下来的调度策略，比如是重传还是新传。在本申请实施例的描述中，经常以HARQ-ACK作为HARQ技术中的反馈信息，应理解，还可以时HARQ-NACK信息，本申请都适用。
应理解，以上列举的反馈信息包括的内容仅为示例性说明，本申请并未限定于此，其他能够指示终端设备对下行数据的接收情况的信息，均落入本申请的保护范围内，例如，该反馈信息还可以包括非连续传输(discontinuous transmission，DTX)信息，该DTX信息可以用于指示终端设备未接收到下行数据。
2.信道状态信息CSI
在无线通信领域，所谓的CSI，就是通信链路的信道属性，CSI是UE对信道状态进行测量后向基站或其他UE反馈的信道状态信息，该信息进一步包括CQI/PMI/RI等信息。它描述了信号在每条传输路径上的衰弱情况，即信道增益矩阵H中每个元素的值，如信号散射(scattering)，环境衰弱(multipath fading or shadowing fading)，距离衰减(power decay of distance)等信息。CSI可以使通信系统适应当前的信道条件，在多天线系统中为高可靠性高速率的通信提供了保障。
3.信道质量指示(channel quality indicator，CQI)信息
在本申请实施例中，CQI可以用来反映物理下行共享信道(physical downlink shared channel，PDSCH)以及PSSCH的信道质量。CQI是信道质量指示信息，用于直接反馈信道质量。基站根据CQI可以进一步确定发送数据采用的调制编码策略(modulation coding strategy，MCS)。当反馈的CQI的值高的时候，可以采用较高的编码调制方式和较高的码率，在有限的资源上承载更多的信息，从而提升数据的传输速率。当反馈的CQI的值较低的时候，可以采用较低的编码调制方式和较低的码率，采用更多的时频资源来传输数据，从而提高数据传输的可靠性。同时，UE通过测量不同频域资源的CQI，使得基站能够将数据调度在信道质量好的频域资源上，从而获得频域调度增益。
作为示例而非限定，在本申请实施例中，可以用0～15来表示PDSCH的信道质量。0 表示信道质量最差，15表示信道质量最好。
在本申请实施例中，终端设备可以在PUCCH或物理上行共享信道(physical uplink shared channel，PUSCH)上向网络设备发送CQI信息。或者，终端设备可以在PSSCH或PSCCH上向另一终端设备发送CQI信息。网络设备或者另一终端设备可以CQI信息根据，确定当前PDSCH或PUSCH的无线信道条件，进而完成针对PDSCH的调度，例如，在本申请实施例中，网络设备可以基于CQI信息确定自适应编码调制(adaptive modulation and coding，AMC)、调制与编码策略(modulation and coding scheme，MCS)、上行传输或下行传输的码率或数据量等。
4.秩指示(rank indication，RI)信息
在本申请实施例中，RI是秩指示信息，用于向基站反馈该信道所能分离出来的层数，层数越多，能同时传输的数据量就越大。RI信息可以用于指示PDSCH或者PSSCH的有效的数据层数，或者说，RI信息可以用于指示终端设备当前可以支持的码字(code word，CW)数。
5.预编码矩阵指示(precoding matrix indicator，PMI)信息
在本申请实施例中，PMI信息可以用于指示码本集合的索引(index)，PMI是UE根据测量的信道质量，向基站或另一UE反馈的发送数据的预编码矩阵标识。基站或另一UE可以根据反馈的PMI信息，来确定对应的预编码矩阵。即，在使用多天线技术，例如，多输入多输出(multiple-input multiple-output，MIMO)技术中，在基带处理中，会进行基于预编码矩阵的预编码处理(precoding)。终端设备可以通过PMI信息指示预编码矩阵，从而，能够提高PDSCH的信号质量。
除此之外，还有一些信息比如CSI-RS的资源指示信息(CSI-RS resource indicator，CRI)，用于向基站反馈测量的多个测量资源中，哪个测量资源测量的信道质量最好。
应理解，以上列举的CSI的具体内容仅为示例性说明，不应对本申请构成任何限定。接收端设备向发送端设备发送的CSI可以包括上述列举中的一项或多项，或者，还可以包括除上述列举之外的其他用于表征CSI的信息，本申请对此不做限定。
在本申请实施例中，发送上行控制信息可以是指发送上行控制信道PUCCH或上行共享信道PUSCH上承载的数据或信息，其中，该数据或信息可以是指经过信道编码后的数据或信息。本申请对此不做限定。
同样地，在本申请实施例中，发送下行控制信息可以是指发送下行控制信道PDCCH或下行共享信道PDSCH上承载的数据或信息，其中，该数据或信息可以是指经过信道编码后的数据或信息。本申请对此不做限定。
同样地，在本申请实施例中，发送侧行控制信息可以是指发送侧行控制信道PSCCH或侧行共享信道PSSCH上承载的数据或信息，其中，该数据或信息可以是指经过信道编码后的数据或信息。本申请对此不做限定。
以下，不失一般性，以一个终端设备与基站之间的交互过程为例详细说明本申请实施例，本申请还包括终端设备与终端设备之间侧行链路的通信过程，例如侧行链路的通信过程，在车辆对外信息交换(vehicle to everything，V2X)业务等，本申请对此不做限定。以一个终端设备与基站之间的交互过程为例，该终端设备可以为处于无线通信系统中与一个或多个网络设备具有无线连接关系的任意终端设备。可以理解的是，处于该无线通信系 统中的任意一个终端设备均可以基于相同的技术方案实现无线通信。本申请对此不做限定。
如背景技术所介绍，为了避免同时发送信道造成冲突，一方面要求基站在调度时就尽量避免不同信道之间的冲突，另一方面在无法避免冲突时定义相应的规则，确定需要发送哪一个信道，从而使基站和UE之间达成一致。如何保证基站和UE之间能够在确定资源的过程中保持一致，以进一步满足终端设备的发送需要，从而提高上行传输的可靠性，是当前需要解决的问题。
当在时域上，不同信道至少占用一个相同的时间单位(子帧，时隙，符号)，就可以认为不同的信道在时域上重叠，我们就认为是有冲突。冲突的处理原则可以大概分为两类：一种处理方法是丢弃(drop)信道，具体地，在不同信道冲突时，其中一个或多个信道不发，只发送冲突信道中的一个。另外一种处理方法是复用信道，具体地，其中一个信道本身不发送，但是将该信道承载的信息放在与其冲突的另外一个信道上发送。当然，还有另外一种通过信道选择的方式实现复用，例如根据一个或多个信道信道承载的信息的种类和状态，选择发送冲突信道中的一个。示例性的，发送调度请求(scheduling request，SR)的PUCCH与发送HARQ-ACK的PUCCH冲突时，如果SR的状态为positive，那么就在SR所在的PUCCH上发送HARQ-ACK信息，反之SR的状态如果为negative，那么HARQ-ACK就在自己的PUCCH上发送。
图2是一例传输过程中的资源选择过程的示意图。如图2所示，在时域上，承载SR的PUCCH和承载非周期的信道状态信息(aperiodic channel state information，A-CSI)的PUSCH发生冲突，当SR的状态为positive，在解决冲突的方法中，可以丢弃承载A-CSI的PUSCH，换言之，丢弃图2中阴影部分示出的信道。
图3是又一例传输过程中的资源选择过程的示意图。如图3所示，在时域上，承载HARQ-ACK的PUCCH和承载A-CSI的PUSCH发生冲突，此时可以将HARQ复用至承载A-CSI的PUSCH上。
以上介绍了两个信道冲突时现有的处理原则，当两个信道之间发生冲突时，可以根据不同的规则进行处理。除了两个信道发生冲突的情况之外，在一种可能的情况中，多个信道也可能同时发生冲突，例如一个信道与至少两个其他信道同时发生冲突，但是该至少两个其他信道之间并没有发生冲突，现有的方案中并没有解决此种情况下的信道冲突问题。
图4是本申请实施例提供的又一例上行传输过程中的资源冲突示意图。如图4所示，当承载SR的PUCCH、和承载HARQ的PUCCH同时与承载A-CSI的PUSCH发生冲突，但是承载SR的PUCCH和HARQ的PUCCH并不冲突时，如何处理资源之间的冲突，是当前亟需解决的问题。
本申请将提供一种确定信道的方法，能够为基站和终端设备确定用于传输的资源，提高传输的可靠性。应理解，本申请将以终端设备向基站的上行传输过程为例，以承载A-CSI的PUSCH和承载SR或者CSI或者HARQ-ACK的PUCCH或PUSCH发生冲突为例具体介绍本申请信道确定的方法。
图5是本申请实施例提供的一例确定信道的方法500的示意性交互图。该方法500可以应用于上述无线通信系统100的终端设备或基站。如图5所示，该方法500包括以下内容。
S510，当第一信道与多个信道中的每个信道在时域上重叠，且所述多个信道中的每个信道在时域上相互不重叠时，根据第一参数信息，从所述多个信道中确定第二信道。
应理解，本申请中第一信道可以是PUSCH，例如不承载上行共享信道(uplink shared channel,UL-SCH)，既承载A-CSI或者SP-CSI的PUSCH。多个信道中的每个信道可以是PUSCH和/或PUCCH，例如承载SR、CSI或HARQ的PUSCH和/或PUCCH，本申请对此不做限定。
还应理解，本申请中的第一信道可以是PSSCH，例如A-CSI的PSSCH。多个信道可以是PSCCH和/或PSFCH，本申请对此不做限定。
还应理解，在本申请中，该多个信道包括至少两个信道，且该多个信道中的每个信道之间没有在时域上重叠，即没有发生任何冲突，但是该多个信道中的每个信道和第一信道在时域上重叠，即发生冲突。
示例性的，如图4示出的示意图，承载SR的PUCCH、和承载HARQ的PUCCH同时与承载A-CSI的PUSCH发生冲突，但是承载SR的PUCCH和HARQ的PUCCH并不冲突，则承载SR的PUCCH、和承载HARQ的PUCCH就可以理解本申请的多个信道中的两个信道，承载A-CSI的PUSCH就可以理解为本申请所说的第一信道，本申请对多个信道中所包括的信道的数量不做限定。
S520，从所述第一信道和所述第二信道中确定待发送的信道。
终端设备和基站可以根据第一参数信息，从所述多个信道中确定第二信道，可以理解为，终端设备和基站从多个信道中选择中一个信道作为第二信道，先解决该第二信道和第一信道的冲突。应理解，第二信道可以理解为优先被选择为解决和第一信道的冲突的信道。
还应理解，这里“待发送的信道”对应到基站侧可以称为“待接收的信道”，这里“待发送的信道”不一定是最终终端设备发送给基站的信道。可选地，解决完该第二信道和第一信道的冲突，如果保留了第一信道为待发送的信道，则第一信道仍然和该多个信道中的其他信道冲突，本申请将继续从多个信道中选择其他信道，继续解决和第一信道的冲突，直到没有冲突为止，最后发送最终保留的信道。或者，解决完该第二信道和第一信道的冲突，如果保留了第二信道为待发送的信道，则第二信道和该多个信道中的其他信道没有冲突，则第二信道就是这里的待发送信道，并由终端设备发送到基站，本申请对此不做限定。
还应理解，第一参数信息可以理解为用于从多个信道中选择信道的参数，换言之，终端设备和基站可以根据该第一参数信息制定一个解决信道冲突的顺序，根据第一参数选择一个第二信道，先解决第二信道和第一信道的冲突。之后如果还有类似的冲突，循环本申请的方法，直到冲突解决为止。
下面将结合不同的第一参数信息的类型，介绍终端设备和基站从多个信道中确定优先解决冲突的第二信道的过程。包括如下不同的方法：
方法一
在一种可能的实现方式中，所述第一参数信息包括发送所述多个信道中的每个信道的起始时间单元的信息，且发送所述第二信道的时间单元的索引在所述多个信道中的时间单元的索引中是最小的。
为了便于终端设备的实现，可以规定按照时间的先后顺序进行处理，具体地，可以按照信道的发送的先后顺序依次进行处理。
应理解，5G移动通信系统支持多种子载波间隔，其中，每种子载波间隔适用不同业务类型或者工作频率，不同的子载波间隔的符号各自对应的循环前缀(cyclic prefix，CP)的长度不同。目前，在载波资源中不同的子载波间隔有15KHz、30KHz、60KHz、120KHz、240KHz，对于不同的服务小区，具有相同或者不同的子载波间隔，从而传输资源具有相同或者不同的时隙长度。
图6是本申请实施例提供的又一例资源确定过程示意图。图6中不同的分量载波(component carrier，CC)，CC 0的子载波间隔是60KHz，CC 1的子载波间隔15KHz，在本申请后续附图和描述中，都以CC 0和CC 1表示不同的载波，分别对应不同的时隙，例如在一个时间长度内，CC 0对应包括时隙4n、时隙4n+1、时隙4n+2和时隙4n+3，CC0对应时隙n。
示例性的，如图6所示，对于CC 0，在时隙4n内包括承载HARQ-ACK的PUCCH，在时隙4n+3内包括承载SR(positive)的PUCCH；对于CC 1，在时隙n内包括承载SP-CSI的PUSCH，其中，承载SP-CSI的PUSCH和承载HARQ-ACK的PUCCH、承载SR(positive)的PUCCH都发生了冲突。
按照方法一，第一参数信息包括承载HARQ-ACK的PUCCH和承载SR(positive)的PUCCH的发送时刻对应的起始时间单元的信息，且开始发送承载HARQ-ACK的PUCCH的时刻对应的时间单元的索引小于开始发送承载SR(positive)的PUCCH的时刻对应的时间单元的索引，换言之，承载HARQ-ACK的PUCCH的起始发送时刻早于承载SR(positive)的PUCCH的起始发送时刻，因此，终端设备和基站可以将承载HARQ-ACK的PUCCH作为第二信道，优先处理承载HARQ-ACK的PUCCH和承载SP-CSI的PUSCH(第一信道)之间的冲突。
如图6的第二步所示，承载HARQ-ACK的PUCCH和承载SP-CSI的PUSCH(第一信道)之间的冲突的解决可以按照图3所示的过程，即将HARQ-ACK复用到承载SP-CSI的PUSCH，保留该PUSCH，即第一信道作为确定的待发送信道。
如图6中的第三步所示，承载HARQ-ACK和SP-CSI的PUSCH和时隙4n+3的承载SR(positive)的PUCCH依然为冲突状态，因此接下来解决承载HARQ-ACK和SP-CSI的PUSCH和时隙4n+3的承载SR(positive)的PUCCH之间的冲突。可以按照图2所示的过程，即丢弃承载HARQ-ACK和SP-CSI的PUSCH，保留该承载SR(positive)的PUCCH，即承载SR(positive)的PUCCH作为确定的待发送信道，可以由终端设备发送给基站。
通过上述方案，基站和终端设备可以根据冲突的信道的发送时域位置对应的时间单元，确定信道之间冲突处理顺序。换言之，优先处理发送时刻在前的信道的冲突，该确定信道的方法可以尽量多的保留和发送控制信息，提高基站和终端设备或者终端设备与终端设备之间传输的可靠性。
应理解，以上仅以PUSCH作为第一信道为例介绍该确定信道的方法，该方法同样适用于终端设备和终端设备之间，以PSSCH作为第一信道、PSCCH或PSFCH作为多个信道的侧行链路通信过程，这里不再赘述。类似地，以下所有方法同样适用于终端设备和终端设备之间，也不再过多赘述。
方法二
在一种可能的实现方式中，所述第一参数信息包括所述多个信道中的每个信道的起始 符号的信息，且所述第二信道的起始符号的索引在所述多个信道中的起始符号的索引中是最小的。
应理解，除了根据方法一中介绍的在多个信道中先确定发送每个信道的起始时刻在前的信道为第二信道，优先解决和第一信道的冲突问题，但是可能在多个信道中，有至少两个信道的发送时间对应同一个时间单元或者时间单元的索引相同，那么可以根据信道的起始符号来确定第二信道。例如，将起始符号在前的信道确定为第二信道，换言之，将起始符号索引最小的确定为第二信道，本申请对此不做限定。
还应理解，在本申请中，所说的发送信道的时间就是指发送每个信道的起始时刻，同理，接收信道的时间就是指接收每个信道的起始时刻。
还应理解，通过起始符号确定第二信道的方法还可以单独使用，即直接根据每个信道的起始符号来确定优先处理哪个信道和第一信道的冲突问题；或者，在根据方法一中介绍的发送信道的时间单元无法确定优先处理哪个信道和第一信道的冲突问题时，再进一步根据信道的起始符号确定优先处理哪个信道和第一信道的冲突问题，本申请对此不做限定。
可选地，可以将和第一信道的起始符号相同的信道确定为第二信道，或者优先处理起始符号相同的信道中的任意两个信道的冲突问题，本申请对此不做限定。
通过上述方案，基站和终端设备可以根据冲突的信道的起始符号，确定信道之间冲突处理顺序。换言之，优先处理起始符号在前的信道的冲突，该确定信道的方法可以尽量多的保留和发送控制信息，提高基站和终端设备或者终端设备与终端设备之间传输的可靠性。
方法三
在一种可能的实现方式中，所述第一参数信息包括接收所述多个信令的起始时间单元的信息，且用于指示所述第二信道的信令的时间单元的索引在所述多个信令的时间单元的索引中是最小的。
应理解，在解决信道冲突之前，对于上行传输，终端设备可以接收基站发送的多个信令，所述多个信令用于指示发送所述多个信道的时间单元。示例性的，信令可以是用于调度的指令，例如DCI、高层信令、无线资源控制(radio resource control，RRC)信令或PHCP层信令等，本申请对此不做限定。
具体地，可以按照网络设备发送调度信令的先后顺序，从多个信道中选择优先处理冲突的第二信道，换言之，先调度的信道优先处理和第一信道的冲突。
在一种可能的实现方式中，如果有多个半静态调度的信道，那么先处理半静态信道之间的冲突。如果存在多于两个半静态调度的信道冲突，则可以结合方法一和方法二中的方法优先进行处理。
图7是本申请实施例提供的又一例资源确定过程示意图。示例性的，如图7所示，对于CC 0，基站在时隙2n内通过下发DCI-1指示终端设备在时隙2n+1发送承载HARQ-ACK的PUCCH，基站在时隙2n+1内调度了下行数据PDSCH，通过下发DCI-2指示终端设备在时隙2n+3发送包括承载A-CSI Report的PUSCH；对于CC 1，在时隙n+1内包括承载SP-CSI的PUSCH，其中，承载SP-CSI的PUSCH和承载HARQ-ACK的PUCCH、承载A-CSI的PUSCH都发生了冲突。那么也就可以理解为，A-CSI的调度要早于HARQ-ACK，虽然A-CSI Report要晚于HARQ-ACK的发送。此时，应该优先处理先调度的用于承载 A-CSI的PUSCH与承载SP-CSI的PUSCH之间的冲突。
通过上述方案，基站和终端设备可以根据冲突的信道的调度信令的接收的起始时刻，确定信道之间冲突处理顺序。换言之，优先处理调度在前的信道的冲突，该确定信道的方法可以尽量多的保留和发送控制信息，提高基站和终端设备或者终端设备与终端设备之间传输的可靠性。
方法四
在一种可能的实现方式中，所述第一参数信息包括所述多个信道中的每个信道承载的不同业务类型的信息。
在5G通信系统中，支持增强型移动宽带(enhanced mobile broadband，eMBB)业务、高可靠低时延通信(ultra reliable and low latency communications，URLLC)业务以及海量机器类通信(massive machine type communications，mMTC)业务以及车辆对外信息交换(vehicle to everything，V2X)业务等。当终端设备上报不同业务类型的信息时，承载不同业务类型信息的信道也可能发生冲突，那么他们之间的冲突解决顺序就可以根据业务类型来确定。
具体地，可以按照如下顺序处理：优先处理承载相同业务类型信息的信道之间的冲突，再处理承载不同业务类型信息的信道之间的冲突。
在一种可能的实现方式中，处理不同业务类型的信道时，按照一定的业务类型的优先级进行处理。例如，优先处理URLLC业务和/或V2X业务，再处理eMBB业务，最后处理mMTC业务。
图8是本申请实施例提供的又一例资源确定过程示意图。示例性的，如图8所示，当承载URLLC业务的HARQ-ACK的PUCCH、承载eMBB业务的HARQ-ACK的PUCCH同时和承载eMBB业务的SP-CSI的PUSCH都发生冲突时，首先优先处理eMBB之间的冲突。如图8中第二步所示，承载eMBB业务的HARQ-ACK的PUCCH同时和承载eMBB业务的SP-CSI的PUSCH冲突解决过程中，将承载eMBB业务的HARQ-ACK和SP-CSI复用在PUSCH上，然后再处理eMBB与URLLC之间的冲突。假设URLLC与eMBB之间的冲突会将eMBB的信道丢弃，因此，如图8中第三步所示，丢弃承载eMBB业务的HARQ-ACK和SP-CSI的PUSCH。同样，此处的URLLC业务也可以是V2X业务，本申请对此不做限定。
在一种可能的实现方式中，可以优先处理URLLC业务与eMBB业务之间的冲突，再处理步骤一中结果与mMTC业务之间的冲突。
图9是本申请实施例提供的又一例资源确定过程示意图。示例性的，如图9所示，当承载URLLC业务的HARQ-ACK的PUCCH、承载mMTC业务的HARQ-ACK的PUCCH同时和承载eMBB业务的SP-CSI的PUSCH都发生冲突时，首先优先处理URLLC业务与eMBB业务之间的冲突。如图9中第二步所示，丢弃承载eMBB业务的SP-CSI的PUSCH。
在一种可能的实现方式中，所述第一信道和所述第二信道承载相同的业务。
换言之，当基站和终端设备确定第一信道之后，根据第一信道承载的业务类型，按照相同的业务类型，从多个信道中确定和第一信道承载相同业务的信道作为第二信道，优先处理该第二信道和第一信道之间的冲突。示例性的，当第一信道是承载URLLC业务的PUSCH，多个信道中分别包括承载URLLC业务的PUCCH、承载mMTC业务的PUCCH 同时和承载eMBB业务的PUCCH，优先处理承载URLLC业务的PUSCH和承载URLLC业务的PUCCH的冲突。
通过上述方案，基站和终端设备可以根据冲突的信道的承载的业务的类型，确定信道之间冲突处理顺序。换言之，优先处理承载的业务的优先级高的信道的冲突，该确定信道的方法可以尽量多的保留和发送控制信息，提高基站和终端设备或者终端设备与终端设备之间传输的可靠性。
应理解，在前面实施例的介绍过程中，可以将PUSCH默认为是第一信道，例如承载A-CSI或者SP-CSI的PUSCH作为第一信道。多个信道中的每个信道可以是PUSCH和/或PUCCH，例如承载SR、CSI或HARQ的PUSCH和/或PUCCH。在实际的通信过程中，第一信道可以是由基站和终端设备根据一定的规则确定的信道。
在一种可能的实现方式中，基站和终端设备可以将与多个信道中的每个信道在时域上都重叠的信道，确定为所述第一信道。换言之，当某个信道同时和多个信道同时冲突时，将该信道确定为第一信道，再按照本申请介绍的方法从多个信道中确定出第二信道，从而优先解决第一信道和第二信道之间的冲突。
图10是本申请实施例提供的又一例资源确定过程示意图。示例性的，如图10所示，当承载URLLC业务的HARQ-ACK的PUCCH、承载eMBB业务的HARQ-ACK的PUCCH、承载URLLC业务的SP-CSI的PUSCH、承载eMBB业务的SP-CSI的PUSCH发生如图所示的冲突。在这种冲突场景中，如果以一个信道和多个信道同时发生冲突来确定第一信道，则图10中的承载URLLC业务的SP-CSI的PUSCH、承载eMBB业务的HARQ-ACK的PUCCH都可以作为第一信道。
可选地，可以根据不同的信道承载的业务的优先级确定第一信道。例如，对于图10中的承载URLLC业务的SP-CSI的PUSCH和承载eMBB业务的HARQ-ACK的PUCCH，URLLC业务的优先级高于eMBB业务的优先级，因此将承载URLLC业务的SP-CSI的PUSCH确定为第一信道。
或者，可以根据不同的信道的起始发送时刻确定第一信道。例如，对于图10中的承载URLLC业务的SP-CSI的PUSCH和承载eMBB业务的HARQ-ACK的PUCCH，承载URLLC业务的SP-CSI的PUSCH的起始发送时刻在承载eMBB业务的HARQ-ACK的PUCCH之前，因此将承载URLLC业务的SP-CSI的PUSCH确定为第一信道。
作为一种示例而非限定，如图10中的第二步所示，将承载URLLC业务的SP-CSI的PUSCH确定为第一信道，优先处理URLLC的业务的信道之间的冲突，将承载URLLC业务的HARQ-ACK和承载URLLC业务的SP-CSI复用到PUSCH上，再按照处理URLLC业务与eMBB业务之间的冲突的原则，丢弃承载eMBB业务的HARQ-ACK的PUCCH，得到图10中第三步所示的处理结果，本申请对此不做限定。
在一种可能的实现方式中，基站和终端设备也可以先各自按照信道的业务类型解决相同业务的信道之间的冲突，之后如果还存在一个信道和多个信道冲突的情况，再按照本申请介绍的多种方案解决信道冲突问题。
图11是本申请实施例提供的又一例资源确定过程示意图。示例性的，如图11所示，当承载URLLC业务的HARQ-ACK的PUCCH、承载eMBB业务的HARQ-ACK的PUCCH、承载URLLC业务的SP-CSI的PUSCH、承载eMBB业务的SP-CSI发生了如图所示的冲 突。此时，除了将满足第一信道确定条件的承载URLLC业务的SP-CSI的PUSCH作为第一信道进行处理之外，还可以优先的根据不同的信道承载的业务的类型进行处理。
具体地，分别处理URLLC的业务的信道之间的冲突，处理eMBB的业务的信道之间的冲突。如图11中的第二步所示，将承载URLLC业务的HARQ-ACK和承载URLLC业务的SP-CSI复用到PUSCH上，将承载eMBB业务的HARQ-ACK和承载eMBB业务的SP-CSI复用到PUSCH上，得到图10中第三步所示的处理结果，此时冲突已经解决，本申请对此不做限定。
方法五
在一种可能的实现方式中，所述第一参数信息包括所述多个信道中的每个信道所承载的信息的优先级信息。
具体地，在处理信道冲突过程中，优先处理承载更高优先级信息的信道间的冲突，处理完成后在仍有冲突的信道中选择次高优先级的信道，解决该信道与其他信道之间的冲突，以此类推，直到解决所有信道之间的冲突。
可选地，如果存在多个优先级相同的信道，那么可以结合以上方法一至方法四中的任意一种，例如按照时间顺序，优先先处理发送时间较早的信道。
可选地，如果一个信道上承载多种优先级的信息，那么取所有信息中的最高优先级进行比较。
应理解，在这种情况下，可以理解为将具有最高优先级的信息对应的信道默认为第一信道，然后优先解决第一信道个多个信道之间的冲突。换言之，当基站和终端设备可以约定认为某个信道为第一信道，之后基站和终端设备只需要从与第一信道都冲突的多个信道中确定第二信道，再处理第一信道和第二信道的冲突。例如承载A-CSI或者SP-CSI的PUSCH作为第一信道。多个信道中的每个信道可以是PUSCH和/或PUCCH，例如承载SR、CSI或HARQ的PUSCH和/或PUCCH。
或者，可选地，第一信道可以是由基站和终端设备根据一定的规则确定的信道。在前面实施例的介绍过程中，介绍了从多个信道中确定第二信道的方法，在实际情况允许的情况下，本申请中介绍的每一种确定第二信道的方案可以用来确定第一信道。换言之，终端设备和基站先从冲突的信道中确定一个信道作为第一信道之后，再确定第二信道，之后再解决相互之间的冲突，本申请对此不做限定。
图12是本申请实施例提供的又一例资源确定过程示意图。表1示出了信道1至信道5的优先级信息。结合表1和图12，图12示出了5个不同的信道1至信道5互相重叠，优先级等级定义如下：P1>P2>P3>P4>P5。
表1
信道编号 优先级
1 P4
2 P2
3 P5
4 P1
5 P3
其中，信道4承载的信息的优先级最高，那么先处理与信道4有关的冲突；信道5的优先级要高于信道3，那么先处理信道4与信道5之间的冲突。假设此时信道5上的信息会复用至信道四，此时信道四的最高优先级仍然是P1，因为信道5上的信息被复用，所以信道5不发送，剩余信道1至信道4。
如图12中的第二步至第三步，在剩余有重叠的信道中，信道4的优先级仍然最高，那么处理与信道4有关的信道冲突。此时假设信道3被丢弃，剩余信道1、信道2和信道4，信道4与其他信道无冲突，冲突的信道只剩信道1和信道2。
信道1上的信息与信道2上的信息会复用至一个信道6，原信道1和信道2都不发。信道6承载优先级为P2和P4的信息，认为信道6的优先级为P2。信道6与信道4无冲突，无重叠，那么信道冲突的处理过程结束，得到图12中第四步的结果。
应理解，在定义优先级的过程中，有多种可能的实现方式。
在一种可能的实现方式中，可以认为不同的控制信息类型之间的优先级是不同的。例如HARQ-ACK>SR>高优先级的CSI>低优先级CSI；URLLC业务>eMBB业务>mMTC业务；V2X业务>eMBB业务>mMTC业务。
可选地，定义优先级还可以根据高层指示，根据不同的QoS来确定优先级，本申请对此不做限定。
通过上述方案，基站和终端设备可以根据冲突的信道的承载的信息的优先级，确定信道之间冲突处理顺序。换言之，优先处理承载的信息的优先级高的信道的冲突，该确定信道的方法可以尽量多的保留和发送控制信息，提高基站和终端设备或者终端设备与终端设备之间传输的可靠性。
方法六
在一种可能的实现方式中，所述多个信道用于承载控制信息，所述第一参数信息包括所述多个信道承载的所述控制信息的类型。
可选地，终端设备和基站可以根据信道中承载的信息类型进行处理。
示例性的，当一个并不承载UL-SCH的PUSCH，例如承载A-CSI或者SP-CSI的PUSCH，与多个承载不同UCI类型的PUCCH/PUSCH冲突，而本身PUCCH/PUSCH之间并不冲突，不同的UCI类型包括HARQ信息，CSI信息和SR信息。
在一种可能的实现方式中，处理顺序可以是优先处理与SR(positive or negative)的冲突，然后处理与CSI的冲突，最后处理与HARQ之间的冲突。具体地，优先处理SR与PUSCH之间的冲突；再处理之后所得到信道与CSI之间的冲突；继续处理前次处理所得到信道与HARQ之间的冲突。
图13是本申请实施例提供的又一例传输过程中的资源选择过程的示意图。如图13所示，假设不同的PUCCH与PUSCH在同一时隙中，他们具有相同的子载波(SCS)间隔。优先处理承载SR(positive)的信道与承载A-CSI的信道之间的冲突，从而丢弃承载A-CSI的信道，最终发送的信道为HARQ和SR。
图14是本申请实施例提供的又一例传输过程中的资源选择过程的示意图。如图14所示，PUCCH与PUSCH可以位于不同的时隙、不同的载波(CC)或者服务小区，他们的子载波间隔也可以不尽相同。优先处理承载SP-CSI的PUSCH与承载A-CSI的PUSCH之间的冲突，从而丢弃承载SP-CSI的PUSCH，最终发送的信道为承载A-CSI的PUSCH、 承载SR(positive)的PUCCH和承载HARQ-ACK的PUCCH。
图15是本申请实施例提供的又一例传输过程中的资源选择过程的示意图。如图15所示，PUCCH与PUSCH可以位于不同的时隙、不同的载波(CC)或者服务小区。优先处理承载A-CSI的PUSCH与承载HARQ-ACK的PUCCH之间的冲突，从而将HARQ-ACK复用到承载A-CSI的PUSCH，再处理和承载SP-CSI的PUSCH之间的冲突，丢弃承载SP-CSI的PUSCH，最终发送的信道为承载HARQ-ACK和A-CSI的PUSCH。
通过上述技术方案，在基站和终端设备的通信过程中，当一个信道(PUSCH)与多个信道同时发生冲突，但是该多个信道之间的任意两个信道并没有发生冲突的情况下，可以通过相同的规则，使得基站和按照预定义的处理顺序，确定传输的信道。具体地，基站和终端设备可以按照信道上所承载的信息类型，如按照上行控制信息UCI的类型，确定信道之间冲突处理顺序；或者，根据冲突的信道的发送时间顺序，确定信道之间冲突处理顺序；或者，根据冲突的信道的调度顺序，确定信道之间冲突处理顺序；又或者，根据冲突的信道承载的不同的业务类型，确定信道之间冲突处理顺序；又或者，根据冲突的信道所承载信息的优先级，确定信道之间冲突处理顺序。上述确定信道的方法可以尽量多的保留和发送控制信息，提高基站和终端设备或者终端设备与终端设备之间传输的可靠性。
应理解，上述介绍的信道确定的方法，可以应用于终端设备和基站之间的通信，例如上行链路的通信过程；还可以应用于终端设备和终端设备之间的通信，例如侧行链路的通信过程，本申请对此不做限定。
