Description

通信方法及装置
本申请要求于2018年07月24日提交中国专利局、申请号为2018108216182、申请名称为《通信方法及装置》的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法及装置。
背景技术
长期演进(Long Term Evolution，LTE)系统采用基于半持续调度(Semi-Persistent Scheduling，SPS)的数据传输机制，传输物理下行共享信道(Physical Downlink Shared Channel，PDSCH)。第五代移动通信技术(the Fifth-Generation，5G)新无线(New Radio，NR)采用类似的传输机制传输PDSCH。
具体的网络设备使用加扰的物理下行控制信道(Physical Downlink Control Channel，PDCCH)，周期性的为用户设备(User Equipment，UE)分配资源，以下称之为SPS资源。每个周期内，UE使用该SPS资源接收PDSCH。如此一来，网络设备无需在每次发送PDSCH之前，下发PDCCH以为UE指定资源。该过程中，SPS的周期、使用的进程数，以及应答资源等通过无线控制资源(Radio Resource Control，RRC)信令配置。其中，应答资源是UE用来向网络设备反馈是否正确接收PDSCH的资源，若UE正确接收PDSCH，则在应答资源上向网络设备发送肯定应答(Acknowledge，ACK)；反之，若UE未能正确接收PDSCH，则在应答资源上向网络设备发送否定应答(Negative Acknowledgement，NACK)。
上述SPS的数据传输机制，需要网络设备周期性的配置发送PDSCH的资源，若某个周期内网络设备无需发送PDSCH，则造成资源的浪费。

其中，所述第一物理信道的载荷包含控制信息和传输块，所述控制信息包含第一信息，所述第一信息用于向用户设备指示应答资源，所述应答资源是所述用户设备向网络设备发送应答信息所使用的资源；

104、在所述应答资源上向网络设备发送应答信息。
本步骤中，用户设备在第一信息指示的应答资源上，向网络设备发送应答信息；相应的，网络设备在第一信息指示的应答资源上，接收用户设备发送的应答信息。其中，应答资源与第一信息指示的应答资源一致，即本步骤中的应答资源，就是步骤101中第一信息指示的应答资源。
本申请实施例提供的通信方法，网络设备在一个或多个候选物理信道资源上向用户设备发送第一物理信道；相应的，用户设备监测候选物理信道集合中的候选物理信道，以在一个或多个候选物理信道的资源上接收第一物理信道。其中，第一物理信道的载荷包含控制信息和传输块，控制信息包含第一信息，第一信息用于向用户设备指示应答资源，应答资源是用户设备向网络设备发送应答信息所使用的资源。当用户设备接收到第一物理信道后，在应答资源上向网络设备发送应答信息；相应的，网络设备在应答资源上接收应答信息。该过程，网络设备无需周期性地为用户设备配置发送第一物理信道的资源，避免资源的浪费。同时，第一物理信道的载荷包含的传输块可以是各种业务类型的传输块，因此，可以满足突发性的高可靠和低延时的URLLC业务的需求。另外，网络设备根据第一物理信道的载荷中的传输块的业务类型，通过第一物理信道的载荷包含的控制信息中的第一信息，可以灵活指定承载应答信息的应答资源。
下面，对上述实施例中，第一物理信道的载荷进行详细说明。
一种可行的实现方式中，第一物理信道的载荷还包含控制信息和传输块的循环冗余校验(Cyclic Redundancy Check，CRC)信息。
具体的，传输块和控制信息可以联合生成CRC信息或其他校验信息，网络设备可以将CRC校验信息包含在载荷中，通过第一物理信道发送给用户设备，实现CRC信息的灵活发送。
需要说明的是，虽然上述是以传输块和控制信息联合生成CRC信息为例对本申请实施例进行详细说明。然而，本申请实施例并不以此为限制，在其他可行的实现方式中，传输块本身也可以不附加CRC信息或其他校验信息；或者，传输块可以单独附加(attach)CRC信息或其他校验信息，如奇偶校验信息等。
下面，对上述实施例中，第一信息，以及第一信息指示的应答资源进行详细说明。
一种可行的实现方式中，第一信息用于向用户设备指示发送应答信息的应答资源，应答信息可以承载在物理上行控制信道(Physical Uplink Control Channel，PUCCH)上。因此，第一信息指示的应答资源可以是在PUCCH发送的应答信息所使用的资源，具体包括：时域资源、频域资源、序列或者码、跳频(hopping)信息。其中：
时域资源，例如可以用起始符合和长度信息表示，或者，用符号集合表示。
频域资源，例如可以用PUCCH所使用的资源块集合表示，资源块集合可以由频域连续或者离散的资源块(Resource Block，RB)组成。
序列或者码，序列可以是随机接入(Zadoff Chu，ZC)序列、离散傅里叶变换(Discrete Fourier Transform，DFT)序列或计算机生成序列(Computer Generated Sequence，CGS)，或者是Zadoff Chu序列、DFT序列或CGS中的任意两个序列的克罗内克(Kronecker)积；码是正交覆盖(Orthogonal Cover Code，OCC)。该些序列或码映射到时域资源或频域资源上，例如，频域上，一个ZC序列、DFT序列或CGS映射到一个或多个RB上；时域上，一个OCC、DFT序列或者CGS映射到2个或多个符号上，序列的长度等于符号的个数。
第一信息用于指示上述时域资源、频域资源、序列或者码、跳频信息中的至少一个。另外，第一信息还可用于指示承载应答信息的PUCCH时隙或子帧。例如，第一信息指示承载应答信息的PUCCH与第一物理信道在相同的时隙内不同的符号上；或者，第一信息指示承载应答信息的PUCCH在第一物理信道之后的第4个时隙。
根据上述可知，当用户设备监测到第一物理信道后，向网络设备发送应答信息时，相应的，网络设备接收该应答信息。网络设备接收应答信息，具体是通过PUCCH，在第一信息指定的时域资源、频域资源或者跳频(hopping)上，通过接收序列或者码资源接收用户设备发送的应答信息。
一种可行的实现方式中，第一信息用于向用户设备指示发送应答信息的应答资源，应答信息可以承载在物理上行共享信道(Physical Uplink Shared Channel，PUSCH)上。因此，第一信息指示的应答资源可以是在PUSCH上发送的应答信息所使用的资源，具体包括：时域资源、频域资源、ACK信道编码信息、序列或码。其中：
时域资源，例如可以用起始符合和长度信息表示，或者，用符号集合表示。
频域资源，例如可以用PUSCH所使用的资源块集合中的子载波的位置表示，子载波的位置在频域上连续或者离散。
ACK信道编码信息，包括信道编码参数，如编码方式、编码类型、码率(code rate) 或者码率集合等。
序列或者码，序列可以是随机接入(Zadoff Chu，ZC)序列、离散傅里叶变换(Discrete Fourier Transform，DFT)序列或计算机生成序列(Computer Generated Sequence，CGS)，或者是Zadoff Chu序列、DFT序列或CGS中的任意两个序列的克罗内克(Kronecker)积；码是正交覆盖(Orthogonal Cover Code，OCC)。该些序列或码映射到时域资源或频域资源上，例如，频域上，一个ZC序列、DFT序列或CGS映射到一个或多个RB上；时域上，一个OCC、DFT序列或者CGS映射到2个或多个符号上，序列的长度等于符号的个数。
第一信息用于指示上述时域资源。频域资源、ACK信道编码信息、序列或码中的至少一个。另外，第一信息还可以指示承载应答信息的PUSCH的时隙或子帧。例如，第一信息指示承载应答信息的PUSCH与第一物理信道在相同的时隙内不同符号上；或者，第一信息指示承载应答信息的PUSCH在第一物理信道之后的第4个时隙。
下面，对上述实施例中，应答信息进行详细说明。
一种可行的实现方式中，上述的应答信息用于指示所述用户设备正确接收所述载荷。
具体的，若用户设备在一个或多个候选物理信道上盲检测成功，正确接收到第一物理信道中的载荷，则向网络设备发送ACK(Acknowledgment确认应答)信息，以向网络设备指示用户设备正确接收载荷。此时，控制信息和传输块联合生成CRC信息。当接收的载荷使得联合生成的CRC信息校验通过时，才发送ACK信息。接收的载荷使得联合生成的CRC信息校验不通过，则未正确接收到载荷。
当用户设备未正确接收载荷时，则不发送应答信息。此时，网络设备在应答资源上接收不到应答信息，则认为载荷没有被用户设备正确接收。
一种可行的实现方式中，上述的应答信息用于指示用户设备正确接收传输块。
具体的，若用户设备在一个或多个候选物理信道上盲检测成功，正确接收到第一物理信道的载荷中的传输块，则向网络设备发送ACK信息，以指示用户设备正确接收传输块。此时，控制信息和传输块分别生成CRC信息。当接收到的载荷使得传输块生成的CRC信息校验通过，且控制信息生成的CRC信息校验通过时，发送ACK信息。
当用户设备未正确接收传输块时，则不发送应答信息。此时，网络设备在应答资源上接收不到应答信息，则认为传输块没有被用户设备正确接收。
一种可行的实现方式中，上述的应答信息用于指示用户设备正确或非正确接收传输块。
具体的，若用户设备在一个或多个候选物理信道上盲检测成功，成功接收到第一物理信道的载荷中的传输块，则向网络设备发送ACK信息，以指示用户设备正确接收传输块；否则，若用户设备在一个或多个候选物理信道上盲检测不成功，没有成功接收到第一物理信道的载荷中的传输块，则向网络设备发送NACK(Non-Acknowledgment非确认应答)信息，以指示用户设备未正确接收到传输块。当用户设备正确接收传输块时，说明控制信息和传输块分别生成CRC信息，传输块生成的CRC信息校验正确，且控制信息生成的CRC信息校验正确；当用户设备未正确接收传输块时，说明控制信 息和传输块分别生成CRC信息，传输块生成的CRC信息校验错误，但控制信息附加的CRC信息校验正确。
需要说明的是，虽然上述是以载荷或传输块的CRC校验是否成功，来判断是否正确接收载荷或传输块的。然而，本申请实施例并不以此为限制，在其他可行的实现方式中，也可以通过其他校验方式判断是否成功接收载荷或传输块。例如，通过判断第一物理信道的检测量是否超过预设门限值，来判断是否正确接收载荷或传输块。
本申请上述实施例中，网络设备向用户设备发送第一物理信道，第一物理信道包含传输块和控制信息，控制信息包含指示应答资源的第一信息，其中，传输块和第一信息可以联合生成附加的CRC。当用户设备正确接收载荷或传输块时，在第一信息指示的应答资源上发送应答信息。网络设备可以通过第一信息灵活指定应答资源的位置，从而可以根据不同的业务类型，满足数据发送的不同时延要求，提高系统数据传输时延的灵活性。特别，当网络设备没有发送第一物理信道时，用户设备不需要发送应答信息，提高了网络设备发送第一物理信道的灵活性。
下面，对上述实施例中，第一物理信道的控制信息进行详细说明。
一种可行的实现方式中，控制信息还包括：发送所述传输块所使用的进程的标识，和/或，所述用户设备的上行物理信道的功率控制信息。
首先，进程标识(Identity，ID)。
具体的，网络设备使用进程ID对应的进程向用户设备发送传输块；网络设备接收的应答信息(主要指ACK信息)与进程ID对应的传输块对应。
例如，网络设备使用进程ID对应的进程向用户设备发送一个或多个传输块，网络设备接收到一个ACK信息，该ACK与进程ID对应的传输块，即一个或多个传输块对应。
再如，网络设备使用进程ID对应的进程向用户设备发送多个传输块，网络设备接收到多个ACK信息，每个ACK信息分别对应一个传输块。
本申请实施例中，进程ID的总数，即进程的总数，可以是预定义的或者由高层信令配置，高层信令例如为RRC ID或MAC CE。
本申请实施例中，第一物理信道的控制信息进一步的还包括发送传输块所使用的进程标识，网络设备接收与进程标识对应的应答信息，可以在数据传输的环回时间内使能多个进程对传输块进行传输，从而提高传输效率。此外，通过利用相同的进程重传传输块，可以提高传输块传输的可靠性。进一步的，网络设备可以灵活配置进程的总数，即进程标识的总数，从而在不同的数据传输的环回时间，满足不同的时延需求。
其次，功率控制信息。
具体的，网络设备可以将上行物理信道的功率控制信息包含在控制信息中，通过第一物理信道发送给用户设备，使得用户设备根据功率控制信息，确定上行物理信道的功率，向网络设备发送上行物理信道。例如，功率控制信息可以是PUCCH的功率控制信息，具体可以包括PUCCH的参考信号或者数据的功率控制信息；再如，功率控制信息可以是PUSCH的功率控制信息，具体可以包括PUSCH的参考信号或者数据的功率信息；又如，功率控制信息可以是探测参考信号(Sounding Reference Signal， SRS)的功率控制信息。
假设用户设备在PUCCH或PUSCH上发送应答信息，则根据功率控制信息，在PUCCH或PUSCH上以相应的功率发送应答信息；相应地，接收PUCCH或PUSCH。
图3A为本申请一实施例提供的通信方法中第一物理信道的发送过程示意图。如图3A所示，第一物理信道包含载荷和CRC信息，载荷包含控制信息和传输块。其中，控制信息包含上述第一信息，另外还可以包括上述的进程ID或功率控制信息。发送过程中，第一物理信道包含的载荷和CRC信息经过信道编码和/或调制，之后，进行资源映射，即将第一物理信道映射到所述一个或多个候选物理信道的物理资源上，然后，在所述物理资源上发送第一物理信道。
图3B为本申请一实施例提供的通信方法中第一物理信道的接收过程示意图。如图3B所示，第一物理信道包含载荷和CRC信息，载荷包含控制信息和传输块。接收过程中，用户设备接收到信号后，进行接资源映射，然后对接收到的信号进行信道译码和/或解调，从而得到CRC信息，根据CRC信息校验控制信息和/或传输块。
本申请实施例中，第一物理信道的控制信息进一步的还包括上行物理信道的功率控制信息。因此，网络设备可以根据不同用户设备的信道条件，调整上行物理信道的功率，从而提高在上行物理信道上发送应答信息的可靠性。
下面，对上述实施例中，如何从候选物理信道集合中选择出一个或多个候选物理信道进行详细说明。
一种可行的实现方式中，网络设备从候选物理信道集合中确定一个或多个候选物理信道时，根据候选物理信道集合的配置，确定一个或多个候选物理信道。相应的，用户设备监测候选物理信道集合中的候选物理信道，以接收网络设备发送的第一物理信道时，具体是根据候选物理信道集合的配置，监测所述候选物理信道集合中的候选物理信道，以接收所述网络设备发送的所述第一物理信道；其中，所述候选物理信道集合的配置包含所述候选物理信道集合中候选物理信道的大小，以及所述候选物理信道集合中候选物理信道的个数。
首先，对候选物理信道进行说明。
具体的，候选物理信道的大小，可以根据候选物理信道使用的资源定义。每个候选物理信道可以对应一个或多个信道单元(Channel Element，CE)，一个CE可以对应一个或多个物理资源。因此，一个候选物理信道对应一个或多个物理资源。其中，物理资源可以是一个或多个物理资源块(Resource Block，RB)，或者，物理资源可以是资源单元组(Resource Element Group，REG)。候选物理信道对应的CE或RB的个分数称之为候选物理信道的大小，或者称之为候选物理信道的聚合级别(Aggregation Level，AL)。
每个候选物理信道对应的物理资源，可以根据候选物理信道的资源配置确定。其中，候选物理信道的资源配置至少包括：候选物理信道可用的时域资源和/或频域资源信息。候选物理信道的资源配置信息，可以包括下述信息中的一个或多个：时域资源、频域资源、发送候选物理信道使用的参考信号(Reference Signal，RS)的参数、候选物理信道的预编码相关信息、候选物理信道到资源的映射参数、天线端口相关的信息。 下面，对该些信息进行详细说明。
时域资源，可以是连续或者离散的符号或者时隙，例如符号的起始位置及其长度信息。
频域资源，可以是连续或者离散的资源块RB的集合，例如连续的24或者48或者96个RB等；其实RB的位置相对于广播信道或者同步信号所在的资源的RB，偏移可以是0、2、4、12、16、38；或者，偏移可以是5、6、7、8、20；或者，偏移可以是28、56等。
发送候选物理信道使用的RS的参数，例如RS序列的初始化值、正交RS序列参数；再如，使用OCC的索引值或者OCC的索引值集合等。
候选物理信道的预编码相关信息，例如，预编码矩阵使用的颗粒度信息等。
候选物理信道到资源的映射参数，例如候选物理信道的单元到资源集合的单元或者单元集合的映射信息。
天线端口相关的信息，例如候选物理信道对应的参考信号与其他信号的准共址(Quasi Co Location，QCL)。
其中，候选物理信道的资源配置的全部或部分信息，可以是预先定义的，也可以是由网络设备通过高层配置或者通知。例如，由RRC配置或者由MAC配置；再如，由RRC IE通知或者由MAC CE通知。另外，候选物理信道的资源配置可以是一个或多个。
其次，对候选物理信道集合进行说明。
具体的，候选物理信道集合可以有一个或者多个，每个候选物理信道集合的配置包含大小及个数，其中，大小是指候选物理信道集合中候选物理信道的大小，个数是指候选物理信道集合中候选物理信道的个数。具体实现时，候选物理信道集合的配置可以是预定义的，此时，候选物理信道集合的配置由协议预定义，因此候选物理信道集合为网络设备和用户设备所共知；或者，候选物理信道集合的配置由高层信令配置或通知，网络设备通过高层信令将多个候选物理通知给用户设备，高层信令例如为RRC IE或MAC CE等。
本申请实施例中，一个候选物理信道的大小可以用该候选物理信道对应的信道单元表示。具体的，一个候选物理信道可以对应L个信道单元，L的取值例如为1、2、4、8或16。一个候选物理信道集合中，每个候选物理信道的大小可以相同或不同。例如，一个候选物理信道集合包含8个候选物理信道，这8个候选物理信道对应的L均为4，即每个候选物理信道对应4个信道单元；再如，一个候选物理信道集合包含8个候选物理信道，其中4个候选物理信道对应的L为2，另外4个候选物理信道对应的L为4。
以上所述一个候选物理信道的集合中，每个候选物理信道的大小可以相同；除此之外，一个候选物理信道的集合中，每个候选物理信道的大小也可以不同，例如，候选物理信道的集合划分为多个子集，每个子集中候选物理信道的大小可以单独指定。
不失一般性，下述实施例中，均是以一个候选物理信道集合中，每个候选物理信道的大小相同为例，对本申请所述方法进行详细说明。
本申请实施例中，候选物理信道集合的配置包含大小以及个数，假设候选物理信 道的大小为L，则候选物理信道集合的配置可以为：
对于L＝1，候选物理信道集合中，可配置的候选物理信道的个数为{0，1，2，3，4，5，6，8}；
对于L＝2，候选物理信道集合中，可配置的候选物理信道的个数为{0，1，2，3，4，5，6，8}；
对于L＝4，候选物理信道集合中，可配置的候选物理信道的个数为{0，1，2，3，4，5，6，8}；
对于L＝8，候选物理信道集合中，可配置的候选物理信道的个数为{0，1，2，3，4，5，6，8}；
对于L＝16，候选物理信道集合中，可配置的候选物理信道的个数为{0，1，2，3，4，5，6，8}。
以总共16个CE为例，则候选物理信道集合的配置如表1所示：
表1候选物理信道的大小与候选物理信道的个数
候选物理信道的大小L 候选物理信道个数
4 4
8 2
16 1
如表1所示，当候选物理信道的大小L＝4时，候选物理信道集合中候选物理信道的个数为4；当候选物理信道的大小L＝8时，候选物理信道集合中候选物理信道的个数为2；当候选物理信道的大小L＝18时，候选物理信道集合中候选物理信道的个数为1。
最后，对候选物理信道集合的配置，和候选物理信道的配置之间的关系进行说明。
一种可行的实现方式中，候选物理信道集合的配置，和上述的候选物理信道的配置可以独立配置或预定义。例如，候选物理信道集合的配置，可以通过索引与候选物理信道的资源配置相关联；再如，候选物理信道集合的配置，可以与一个或多个候选物理信道的资源配置相关联；又如，候选物理信道的资源配置，可以与一个或多个候选物理信道集合的配置相关联。
一种可行的实现方式中，候选物理信道集合的配置，和上述的候选物理信道的配置可以联合配置或者预定义。联合配置时，网络设备根据候选物理信道集合的配置，确定第一物理信道使用的一个或多个候选物理信道。
例如，网络设备可以根据用户设备的信道条件，以及传输的可靠性需求，确定候选物理信道的大小。其中，一个候选物理信道包含一个或多个CE。
具体的，网络设备可以基于不同的可靠性需求，以及该可靠性需求对应的信干噪比(Signal to Interference Noise Ratio，SINR)与目标误块率(Block Error Ratio，BLER)性能曲线，确定候选物理信道的大小(即该候选物理信道对应的CE个数)。通常情况下，可靠性需求越高，即BLlER越低，则候选物理信道的大小越小，即候物理信道对应的CE个数越少。举例来说，对于10％的目标BLER需求，候选物理信道的大小为2，即候选物理信道使用2个CE；对于1％的目标BLER需求，候选物理信道的大小为8，即候选物理信道使用8个CE。
再如，网络设备可以根据可用的CE总数，考虑不同用户设备的复用，从候选物 理信道集合中选择一个或多个候选物理信道发送第一物理信道。选择过程中，主要考虑候选物理信道的位置。
具体的，为了避免不用用户设备所使用的候选物理信道所占用的CE相互阻塞。当给定信道单元的个数时，候选物理信道对应的信道单元的索引，可以根据预定义的随机化函数得出。随机化函数例如为如下哈希(Hash)函数：

其中，

或者，

Y -1＝n RNTI≠0，D＝65537，A＝39827，或者，A＝39829，或者，A＝39839，
N CE为信道单元的总数，信道单元索引从0到N CE-1；
n CI＝0或者高层信令配置的载波指示域值；

其中，

取值的最大值。
需要说明的是，上述参数可以是其他具体取值，本申请并不限定。
上述实施例中，网络设备根据候选物理信道集合的配置，确定一个或多个候选物理信道。其中，候选物理信道集合的配置包含候选物理信道的大小以及个数。具体实现过程中，网络设备可以根据用户的信道条件、数据传输的可靠性需求和时延需求，灵活选择候选物理信道的大小，并从候选物理信道集合中选择一个或多个候选物理信道，在选择出的一个或多个候选物理信道的资源上发送第一物理信道，实现链路自适用，提高传输的可靠性，并满足发送的时延需求。
还需要说明的是，候选物理信道可以对应一个CE或多个CE，多个CE对应的候选物理信道可以聚合在一起，组成一个聚合的候选物理信道。上述的多个CE的个数和位置的确定方法，可以应用于候选物理信道的聚合。也就是说，以上CE的个数和位置的确定方法，可以替换为候选物理信道的个数和位置的确定方法，从而得到聚合的候选物理信道的资源。使用聚合的候选物理信道的资源发送第一物理信道的过程，与上述图3所示过程类似。但是，载荷大小以及信道编码和/或调制、资源映射过程等要考虑聚合的候选物理信道的实际资源。
下面，对候选物理信道集合的配置包含候选物理信道的聚合信息时，网络设备如何通过聚合的候选物理信道的资源，向用户设备发送第一物理信道进行详细说明。
具体的，候选物理信道的聚合信息指示相同或不同大小的候选物理信道的聚合。例如，聚合的候选物理信道使用相同的物理信道的资源集合；再如，聚合的物理信道使用不同的物理信道的资源集合。
举例来说，候选物理信道集合的配置与两个候选物理信道的资源集合(S1和S2)相关联。候选物理信道集合的配置在资源集合S1中的候选物理信道为C 1，i，i＝0，1，……，N 1-1；候选物理信道集合的配置在资源集合S2中的候选物理信道为C 2，i，i＝0，1，……， N 2-1。则候选物理信道C 1，i与候选物理信道C 2，i组成一个聚合的候选物理信道M i，i＝0，1，……，N-1；，其中，N为N 1和N 2中的最小值。
本申请实施例中，候选物理信道集合的配置包含候选物理信道的聚合信息，该候选物理信道的聚合信息可以是给定候选物理信道的大小，以及各大小对应的聚合候选物理信道的个数。以总共16个信道单元为例，给定候选物理信道的大小以及对应的聚合候选物理信道的个数可以用标和表2表示。
表2候选物理信道的大小与候选物理信道的个数
Figure PCTCN2019097500-appb-000008
表3聚合候选物理信道的大小与聚合候选物理信道的个数
Figure PCTCN2019097500-appb-000009
如表2与表3所示，当候选物理信道的大小L＝4时，资源集合S1中候选物理信道的个数为4，资源集合S2中候选物理信道的个数为4，此时，聚合候选物理信道的大小为8，聚合候选物理信道的个数为4。
本申请上述实施例中，网络设备可以根据候选物理信道集合的配置，确定多个候选物理信道作为聚合候选物理信道。网络设备可以根据用户设备的条件，以及数据传输的可靠性和时延要求，选择聚合候选物理信道，进一步的提高传输的可靠性，并满足发送的时延需求。
进一步的，网络设备在根据候选物理信道集合的配置，确定一个或多个候选物理信道时，还可以考虑载荷的格式。此时，网络设备根据载荷的格式和候选物理信道集合的配置，确定所述一个或多个候选物理信道；相应的，用户设备根据候选物理信道集合的配置，监测所述候选物理信道时，具体是根据所述载荷的格式和所述候选物理信道集合的配置，监测所述候选物理信道。其中，所述载荷的格式是预定义的或者由高层信令配置。
具体的，载荷的格式，可以根据载荷的内容、大小或结构等不同定义。其中，载荷的内容可以用于不同的业务类型或用途等；载荷的大小可以是20比特、32比特、44比特、64比特或80比特等；载荷的结构可以是载荷的不同域(field)的构成或者不同(field)的取值。
进一步的，网络设备在根据候选物理信道集合的配置，确定一个或多个候选物理信道时，还可以考虑传输块的格式。此时，网络设备根据传输块的格式和候选物理信道集合的配置，确定所述一个或多个候选物理信道；其中，所述传输块的格式是预定义的或者由高层信令配置。具体实现时，可以将传输块的格式包含在候选物理信道集 合的配置中，此时，候选物理信道集合的配置支持传输块的格式；或者，传输块的格式和候选物理信道集合的配置独立。
具体的，传输块的格式，可以根据传输块的内容、大小或结构等不同定义。其中，传输块的内容可以用于不同的业务类型或用途等；传输块的大小可以是20比特、32比特、44比特、64比特或80比特等；传输块的结构可以是传输块的不同域(field)的构成或者不同(field)的取值。
本申请实施例中，预定义或者通过高层信令配置载荷的格式或传输块的格式时，也可以在候选物理信道集合的配置中，设置载荷的格式或传输块的格式。此时，候选物理信道集合的配置包含候选物理信道集合包含的候选物理信道的大小和个数，以及载荷的格式或传输块的格式。具体地，可以对应于所述载荷的格式配置候选物理信道的个数、或者候选物理信道的大小以及候选物理信道的个数。
下面，以载荷的格式包括F0和F1格式，或者，传输块的格式包括F0和F1为例，对应的候选物理信道的个数以及大小如表4所示。
表4载荷(或者传输块)的格式，以及候选物理信道的大小和个数
Figure PCTCN2019097500-appb-000010
根据表4可知，当载荷(或传输块)的格式为F0时，候选物理信道集合中候选物理信道的大小可以为2、4或8，候选物理信道的个数分别可以为4、2或1。当载荷(或传输块)的格式为F1时，候选物理信道的大小可以为4、8或16，候选物理信道的个数分别可以为4、2或1。
上述表4实施例中，候选物理信道集合的配置是根据载荷(或传输块)的格式确定出的。然而，申请并不以此为限制，在其他可行的实现方式中，候选物理信道集合的配置和载荷(或)传输块的格式是独立的。具体的，可参见表5。
表5候选物理信道的大小和个数
Figure PCTCN2019097500-appb-000011
请参照表5，假设载荷(或传输块)共有F0、F1、F2和F3四种格式，第一物理信道可用的格式是F0和F1，则对于F0和F1格式的第一物理信道而言，候选物理信道集合都有4种可选的方式。
根据载荷(或传输块)的格式，和候选物理信道集合的配置，确定一个或多个候选 物理信道，一个典型的实现过程如下：
网络设备根据载荷(或传输块)的格式，确定第一物理信道的载荷或者传输块的大小、可靠性、时延等性能要求；同时，考虑用户设备的信道条件，根据候选物理信道集合的配置，确定一个或多个候选物理信道占用的CE的个数和位置。通常情况下，传输的可靠性需求越过，则一个或多个候选物理信道占用的CE越多。此时，网络设备可以基于不同的可靠性需求，以及该可靠性需求对应的SINR目标BLER性能曲线，确定候选物理信道的大小(即该候选物理信道对应的CE个数)。通常情况下，可靠性需求越高，即BlER越低，则候选物理信道的大小越小，即候物理信道对应的CE个数越少。举例来说，对于10％的目标BLER需求，候选物理信道的大小为2，即候选物理信道使用2个CE；对于1％的目标BLER需求，候选物理信道的大小为8，即候选物理信道使用8个CE。
另外，网络设备根据载荷(或传输块)的格式，确定第一物理信道的载荷或者传输块的大小、可靠性、时延等性能要求；同时，根据可用的CE总数，考虑不同用户设备的复用，从候选物理信道集合中选择一个或多个候选物理信道发送第一物理信道。
上述实施例中，网络设备根据第一物理信道的载荷(或传输块)的格式，以及候选物理信道集合的配置，从候选物理信道集合中确定出一个或多个候选物理信道，在一个或多个候选物理信道的资源上发送第一物理信道集合。该过程中，网络设备可以根据不同业务需求，灵活选择不同的载荷(或传输块)的格式，同时，根据用户设备的信道条件，以及数据传输的可靠性和时延要求，选择候选物理信道，提高了传输的可靠性，并满足发送的时延需求。对于用户设备来说，在候选物理信道集合中，检测多个候选物理信道，利用可选的载荷的格式，可以减少盲检测次数，从而减少用户设备发送应答信息的时延，并降低了盲检测的复杂度。
一种可行的实现方式中，网络设备从候选物理信道集合中确定一个或多个候选物理信道时，具体根据所述第一物理信道的重复次数配置信息，从所述候选物理信道集合中获得所述一个或多个候选物理信道，所述多个候选物理信道形成候选物理信道组合，所述候选物理信道组合中至少两个候选物理信道占用不同的时间单元上；相应的，用户设备监测候选物理信道集合中的候选物理信道，以接收网络设备发送的第一物理信道，具体是根据所述第一物理信道的重复次数配置信息，在至少两个不同的时间单元上监测候选物理信道集合中的候选物理信道组合，以接收网络设备发送的所述第一物理信道；其中，所述第一物理信道的重复次数配置信息指示所述第一物理信道的重复次数的集合；所述候选物理信道组合中的每个候选物理信道的载荷相同；所述候选物理信道组合的配置是预定义的或者由高层配置的。
具体的，第一物理信道的重复次数可以为1、2、4、8等，相应的，网络设备可以配置的重复次数为1、2、4、8等。本实施例中，重复次数配置信息指示第一物理信道的重复次数的集合，重复次数的集合至少包含一个重复次数值。例如，第一物理信道的重复次数的集合可以是{1，2}、{2，4}或者{4，8}等；再如，第一物理信道的重复次数的集合可以是{1}、{2}、{4}、{8}等，此时，重复次数值是一个。
本实施例中，网络设备根据第一物理信道的重复次数配置信息，为第一物理信道确 定一个或多个候选物理信道后，在一个或多个候选物理信道的资源上发送第一物理信道。此时，若候选物理信道为多个，则网络设备多个候选物理信道的资源上发送的第一物理信道的载荷相同。并且，在多个候选物理信道的资源上发送的第一物理信道可以有相同或不同的冗余版本。
具体的，相同的载荷经过信道编码之后可以得到相同或不同的冗余版本(Redundancy Version，RV)。例如，对载荷采用低密度奇偶校验码(Low Density Parity Check Code，LDPC)或者极化码(Polar Code)等编码之后，得到母码对应的编码比特序列，通过截取、打孔或者速率匹配的方式得到不同的冗余版本。
本实施例中，网络设备根据第一物理信道的重复次数，为第一物理信道确定一个或多个候选物理信道后，在一个或多个候选物理信道的资源上发送第一物理信道。此时，若候选物理信道为多个，则多个候选物理信道形成候选物理信道组合，候选物理信道组合中至少有两个候选物理信道位于不同的时间单元上，候选物理信道组合的配置是预定义的或者由高层配置的。其中，时间单元可以是时隙、子帧等。以时间单元为时隙为例，假设候选物理信道集合为{Ci，i＝0，1，…，Nc-1}，其中，Ci为候选物理信道，Nc为候选物理信道的个数。对于两个不同的时隙Slot0和Slot1，Slot0的候选物理信道Ci总是与Slot1的候选物理信道Ci组合(也可以称之为Slot1的候选物理信道Ci总是Slot0候选物理信道Ci的重复)；再如，Slot0的候选物理信道Ci总是与Slot1的候选物理信道Cj组合，j＝(i+Offset)mod Nc，i＝0，1，2，…，Nc-1(也可以称之为Slot1的候选物理信道Cj总是Slot0候选物理信道Ci的重复)。该过程中，不同的时间单元可以通过高层信令配置，如通过RRC IE配置。
一个典型的实施例中，网络设备可以通过候选物理信道集合的配置，进一步指定候选物理信道的不同的监控时机(Monitor Occasion)，该不同的监控时机例如为不同的时隙或子帧。
上述实施例中，网络设备根据第一物理信道的重复次数配置信息，在多个候选物理信道上发送第一物理信道，可以进一步的提高传输的可靠性。另外，通过重复次数配置信息指示重复次数的集合，重复次数的集合中包含多个可选的重复次数取值，使得网络设备可以根据用户设备的信道条件，灵活选择重复的次数，增加重复次数可以提供传输的可靠性，减少重复次数，可以降低疏忽局传输的时延。因此可以在可靠性和时延之间进行折衷，从而灵活适应数据传输的灵活性。
进一步的，上述实施例中，当网络设备根据第一物理信道的重复次数配置信息，为第一物理信道确定一个或多个候选物理信道时，第一载荷的控制信息还包括第二信息，该第二信息指示所述第一物理信道的重复次数值；所述重复次数值属于所述第一物理信道的重复次数配置信息指示的重复次数的集合。
本实施例中，第一物理信道的控制信息进一步的还包括第一物理信道的重复次数值，该重复次数值属于重复次数配置信息指示的重复次数的集合。用户设备获知重复此数值后，可以精确获得第一物理信道的结束的时刻，可以精确获知第一物理信道和应答资源(信道)的定时，便于快速反馈应答信息。
一种可行的实现方式中，网络设备从候选物理信道集合中确定一个或多个候选物 理信道时，具体根据第一物理信道的重复周期配置，从候选物理信道集合中获得一个或多个候选物理信道。其中，重复周期配置是预定义的或者由高层配置的。例如，由RRC IE配置或者由MAC CE通知；再如，由RRC IE配置并由MAC CE通知。
本实施例中，重复周期配置可以是1、2、4、5、6、8等多个时间单元，时间单元例如可以是符号、时隙、子帧、毫秒(ms)或者信道的配置周期等。在第一物理信道的重复周期内，不同的第一物理信道的资源位置可以由高层信令配置或通知。例如，由RRC IE配置或者由MAC CE通知；再如，由RRC IE配置并由MAC CE通知。下面，以时间窗为20个时间单元为例，通过位图(bitmap)对第一物理信道的重复配置周期进行详细说明。具体的，可参见图4A、图4B和图4C。
图4A为本申请一实施例提供的通信方法所适用的重复周期配置示意图。请参照图4A，时间窗的重复周期为20个时间单元，其中第1个和第2个时间单元用于重复发送第一物理信道，则位图可以为1100000000000000000000。其中，第1个时间单元和第2个时间单元，即发送第一物理信道的资源如图中方格填充部分所示。
图4B为本申请另一实施例提供的通信方法所适用的重复周期配置示意图。请参照图4B，时间窗的重复周期为20个时间单元，其中第1个和第4个时间单元用于重复发送第一物理信道，则位图可以为100100000000000000000000。其中，第1个时间单元和第2个时间单元，即发送第一物理信道的资源如图中方格填充部分所示。
图4C为本申请又一实施例提供的通信方法所适用的重复周期配置示意图。请参照图4C，时间窗的重复周期为20个时间单元，其中第1个至第4个时间单元用于重复发送第一物理信道，则位图可以为111100000000000000000000。其中，第1个时间单元至第2个时间单元，即发送第一物理信道的资源如图中方格填充部分所示。
根据上述图4C可知，用于重复发送第一物理信道的资源，可以是时域上连续的资源，从而可以降低传输的时间延迟。根据上述图4A与图4B可知，用于重复发送第一物理信道的资源，可以是时域上离散的资源，从而可以实现时间分集，提高传输可靠性。
需要说明的是，上述实施例中，在重复周期内发送的各个第一物理信道，对其信道编码得到的编码比特序列可以相同也可以不同。也就是说，各个第一物理信道的信道编码的冗余版本可以相同或不同。其中，冗余版本可以是预定义的。再请参照图4C，在一个时间窗的第1个时间单元至第4个时间单元上，第一物理信道的信道编码的冗余版本可以分别为0、2、3、1；在另一个时间窗的第1个时间单元至第4个时间的单元上，第一物理信道的信道编码的冗余版本可以分别为1、1、2、2。
另外还需要说明的是，每个时间窗内，冗余版本可以是预定义的，并由第一物理信道所使用的资源导出。例如，由第一物理信道所使用的时隙索引(Slot index)、符号索引(symbol index)或RB索引(RB index)等。例如，假设一个时间窗内，即一个周期内有P个用于重复发送第一物理信道的时间单元，时间单元(time unit index)的索引为K，则第一物理信道使用的冗余版本为(k+offset)mod Q，k＝0，1，…，P-1，offset为偏移值，Q为信道编码冗余版本的个数，可以为0，1，…，P-1，可以预定义或者由高层信令配置。
上述实施例中，网络设备根据第一物理信道的重复周期配置，向用户设备发送第一 物理信道。在重复周期配置的时间窗内的各个第一物理信道，可以采用相同的冗余版本，可有效利用各个第一物理信道在各个时间单元的时域、频域或空域的分集特性，进一步的提高传输的可靠性。另外，在重复配置周期的时间窗内的不同时间单元上采用不同的冗余版本，从而可以利用信道的编码增益，提高传输的可靠性。
上述实施例中，网络设备在一个或多个候选物理信道的资源上向用户设备发送第一物理信道，第一物理信道监测候选物理信道集合中的候选物理信道的资源，以在一个或多个候选物理信道资源上接收网络设备发送的第一物理信道。为了通知用户设备盲检测，网络设备在一个或多个候选物理信道的资源上向用户设备发送第一物理信道之前，还向用户设备发送第一配置信息；相应的，用户设备接收该第一配置信息，该第一配置信息用于指示用户设备监测候选物理信道集合中的候选物理信道。
需要说明的是，虽然上述各实施例是以网络设备每次向要用户设备发送的第一物理信道的载荷都包含第一信息，即用于指示应答资源的第一信息为例，对本申请所述方法进行详细说明。然而，本申请实施例并不以此为限制，在其他可行的实现方式中，网络设备向用户设备发送第二物理信道，该第二物理信道包含传输块但不包含第一信息。此时，网络设备向用户设备发送第二控制信道之前，还向所述用户设备发送第二配置信息；相应的，用户设备接收该第二配置信息，该第二配置信息用于指示所述用户设备检测第二物理信道；所述第二物理信道对应的应答资源由高层信令或者下行控制信息通知。
需要指出的是，基站可以单独配置并发送第一/第二配置信息，也可以同时配置并发送第一/第二配置信息。但是，第一物理信道和第二物理信道不占用相同的物理资源。典型地，第一物理信道和第二物理信道分别占用不同的时间单元，例如分别占用不同的时隙。例如基站通过第一配置信息指示第一物理信道的候选物理信道发生的时间单元集合为A＝{s1，s2，…，s M},M为正整数，基站通过第二配置信息指示第二物理信道发生的时间单元集合为B＝{t1，t2，…，t N}，N为正整数。A和B的交集为空集。
上述实施例中，网络设备可以根据第一配置信息和/或第二配置信息，指示用户设备检测第一物理信道和/或第二物理信道，第一物理信道的载荷包含传输块和控制信息，第二物理信道的载荷包含传输块，第二物理信道的对应的应答资源由高层信令或者下行控制信息通知。具体实现时，网络设备可以根据实际的业务情况，选择向用户下发第一配置信息和/或第二配置信息，灵活满足不同业务的吞吐量、可靠性和时延等性能需求。特别，当同时配置了第一配置信息和第二配置信息的时候，第二配置信息对应的应答资源通过高层信令或下行控制信息通知，用户设备总是在应答资源上发送ACK或者NACK，便于网络设备利用发送的信号，对信道进行测量，有利于提高第一配置信息配置的信道的发送和接收性能。
需要说明的是，本申请实施例中，候选物理信道集合的配置信息(即候选物理信道集合的配置相关的信息)、第一物理信道的重复次数配置信息、第一配置信息、第二配置信息、第一物理信道的重复周期配置信息(即第一物理信道的重复周期配置的相关信息)等，均可以预先配置或通过高层信令配置。具体的，可参见图5，图5为本 申请一实施例提供的通信方法所适用的高层信令收发示意图，包括：
201、网络设备确定配置信息；
202、网络设备通过高层信令向用户设备发送所述配置信息。
具体的，当上述的配置信息通过高层配置时，网络设备确定配置信息并通过高层信并向用户设备发送所述配置信息，相应的，用户设备接收该高层信令，该高层信令可以包含候选物理信道集合的配置信息(即候选物理信道集合的配置相关的信息)、第一物理信道的重复次数配置信息、第一配置信息、第二配置信息或第一物理信道的重复周期配置信息(即第一物理信道的重复周期配置的相关信息)等。所述高层信令包括但不限于RRC IE和MAC CE以及它们的组合(例如，RRC IE配置候选物理信道集合的信息，MAC CE进一步限定特定的选择信息)。
