Description

一种通信方法及装置
相关申请的交叉引用
本申请要求在2021年01月22日提交中国专利局、申请号为202110091091.4、申请名称为“一种通信方法及装置”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
新无线(new radio，NR)系统等无线通信系统中，终端设备可以通过物理上行共享信道(physical uplink shared channel，PUSCH)发送用户相关的上行业务以及上层信令数据。PUSCH可以是基站通过下行控制信息(downlink control information，DCI)调度的，也可以是通过高层配置的。DCI调度的PUSCH一般称为动态授权(dynamic grant，DG)PUSCH，高层配置的PUSCH一般称为配置授权(configured grant，CG)PUSCH。DG PUSCH和CG PUSCH在时域上重叠时，DCI到CG PUSCH的时间间隔要大于或者等于N2，N2为PUSCH的准备时长(PUSCH preparation time)。
如果DG PUSCH和CG PUSCH在时域上重叠时，终端设备将发送DG PUSCH，不发送CG PUSCH。终端设备的物理层收到DCI后，开始准备发送DG PUSCH；终端设备的物理层将DCI递给终端设备的媒体接入控制(medium access control，MAC)层后，终端设备的MAC层将准备好的协议数据单元(protocol data unit，PDU)递给终端设备的物理层，以便终端设备在DG PUSCH中发送该PDU，不发CG PUSCH。此时终端设备的物理层和MAC层的处理可以是相互独立的。
考虑到DG PUSCH和CG PUSCH中承载的数据对应的逻辑信道的优先级不同，此时MAC层会根据逻辑信道的优先级，选择将DG PUSCH对应的PDU，或者CG PUSCH对应的PDU递给物理层。由于物理层不能够确定DG PUSCH和CG PUSCH中哪个逻辑信道优先级更高，所以如果物理层收到DCI后开始准备发送DG PUSCH，但是MAC层递的是CG PUSCH对应的PDU，会导致不一致，物理层可能会丢弃两个PUSCH，对性能造成影响。

其中，l是符号索引，μ等于0或者1时，C 1＝1，μ等于2时，C 1＝2，C 2和C 3是高层配置的，例如RRC参数配置的。Δ i为标准协议38.211中的5.3.1章节中的表格5.3.1-1，具体可以参考如下表X所示。

上述表格中，μ是子载波间隔索引，用于确定子载波间隔，具体的，子载波间隔等于15kHz×2 μ。
如前所述，本申请实施例中，存在两种PUSCH，DG PUSCH和CG PUSCH。如图3所示，DG PUSCH和CG PUSCH在时域上重叠时，DCI到CG PUSCH的时间间隔要大于或者等于PUSCH准备时长N 2。其中，重叠包括完全重叠，以及部分重叠。DG PUSCH和CG PUSCH在时域上重叠时，可以是CG PUSCH在DG PUSCH之前，也可以是CG PUSCH在DG PUSCH之后，本申请并不限定。
本申请实施例中，当DG PUSCH和CG PUSCH在时域上重叠时，如果没有配置按照逻辑信道的优先级选择发哪一个授权(grant)，即选择发哪个PUSCH进行传输，那么默认发送DG PUSCH，即在DG PUSCH中发送数据；如果配置了按照逻辑信道的优先级选择哪一个grant，即选择哪个PUSCH进行数据传输，那么如果DG PUSCH中承载的数据对应的逻辑信道优先级高于CG PUSCH中承载的数据对应的逻辑信道优先级，那么在DG PUSCH中发送数据；反之亦然。
本申请实施例中，DG PUSCH和PUCCH在时域上可能重叠。如图4所示，DG PUSCH和PUCCH在时域上重叠时，调度DG PUSCH的DCI到基准时刻S0之间的时间间隔大于或等于

其中，i＝1,2,3···等；公式(3)中的参数的含义可以参考公式(1)中的描述，在此不再赘述。
DG PUSCH和用于承载调度请求(scheduling request，SR)的PUCCH在时域上重叠时， 如果没有配置按照逻辑信道的优先级选择发DG PUSCH还是SR，那么默认发送DG PUSCH，即在DG PUSCH中发送数据；如果配置了按照逻辑信道的优先级选择发DG PUSCH还是SR，那么如果DG PUSCH中承载的数据的逻辑信道优先级高于PUCCH中承载的SR的逻辑信道优先级，那么在DG PUSCH中发送数据；反之亦然。
本申请提供一种方法，可以应用于在DG PUSCH和承载SR的PUCCH在时域上重叠，或者DG PUSCH和CG PUSCH在时域上重叠的场景中，下面将详细描述。
本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
参见图5，为本申请实施例提供的一种通信方法流程示意图。图5中，以网络设备与终端设备之间交互为例进行说明，网络设备执行的操作也可以由网络设备内部的芯片或模块执行，终端设备执行的操作也可以由终端设备内部的芯片或模块执行。该方法包括：
步骤501：网络设备向终端设备发送第一下行控制信息。
其中，所述第一下行控制信息用于调度第一物理上行信道，所述第一物理上行信道用于承载第一信息。
可选地，第一物理上行信道可以为PUSCH。
步骤502：终端设备接收来自网络设备的第一下行控制信息。
可选地，本申请实施例中，网络设备还可以向终端设备调度第二物理上行信道，第二物理上行信道用于承载第二信息。
第二物理上行信道可以为PUSCH或者PUCCH。第二物理上行信道为PUSCH时，可以为配置授权PUSCH。例如网络设备向终端设备发送无线资源控制(radio resource control，RRC)消息，该RRC消息用于调度配置授权PUSCH。第二物理上行信道为PUCCH时，可以为配置的PUCCH。例如网络设备向终端设备发送无线资源控制(radio resource control，RRC)消息，该RRC消息用于配置PUCCH。
可选地，网络设备还可以向终端设备发送第一配置信息，第一配置信息用于指示上行物理信道重叠时基于逻辑信道优先级从重叠的上行物理信道中确定进行传输的上行物理信道，也就是说，第一配置信息用于指示在MAC层按照逻辑信道优先级进行数据传输。从重叠的上行物理信道中确定进行传输的上行物理信道，可以理解为从CG和DG中选一个grant，或者在grant和SR中按照逻辑信道优先级选一个。当选择SR时，即在PUCCH上发SR。在协议中，第一配置信息为lch-BasedPrioritization，lch-BasedPrioritization的具体含义可以参考第三代伙伴计划(the 3rd generation partnership project，3GPP)release15或16等技术标准TS(Technical Specification)38.331文献中6.3.2章节的相关描述。
此时，终端设备可以根据所述第一信息对应的逻辑信道优先级和所述第二信息对应的逻辑信道优先级，发送所述第一物理上行信道和所述第二物理上行信道中的一个物理上行信道。其中，发送第一物理上行信道，可以是指在第一物理上行信道中发送第一信息；发送第二物理上行信道，可以是指在第二物理上行信道中发送第二信息。
具体的，所述第一物理上行信道中承载的第一信息的逻辑信道优先级大于所述第二物理上行信道中承载的第二信息的逻辑信道优先级时，终端设备在第一物理上行信道中发送第一信息，不在第二物理上行信道中发送第二信息；所述第一物理上行信道中承载的第一 信息的逻辑信道优先级小于所述第二物理上行信道中承载的第二信息的逻辑信道优先级时，终端设备在第二物理上行信道中发送第二信息，不在第一物理上行信道中发送第一信息。
需要说明的是，第一信息对应多个逻辑信道时，第一信息对应的逻辑信道优先级，可以是指第一信息对应的多个逻辑信道中，优先级最高的逻辑信道的优先级；同样的，第二信息对应多个逻辑信道时，第二信息对应的逻辑信道优先级，可以是指第二信息对应的多个逻辑信道中，优先级最高的逻辑信道的优先级。另外，没有数据的逻辑信道的优先级最低。
逻辑信道的优先级具体如何配置，本申请实施例并不限定，在此不再赘述。
下面分别以第二物理上行信道为配置授权PUSCH或者PUCCH为例，分别进行描述。
实施例一：第二物理上行信道为配置授权PUSCH，第一时长可以是指在配置第一配置信息时的PUSCH准备时长。
实施例一中，以网络设备向终端设备发送了第一配置信息为例进行描述。
如果第一物理上行信道和第二物理上行信道在时域上重叠，第一下行控制信息与第二物理上行信道之间的间隔大于或等于第一时长。第一时长大于第二时长，第二时长为PUSCH准备时长。
实施例一中，所述第二时长为PUSCH准备时长，是指所述第二时长为所述第一物理上行信道和第二物理上行信道在时域上没有重叠时的PUSCH准备时长；或者，所述第二时长为PUSCH准备时长，是指所述第二时长为，没有配置第一配置信息时的PUSCH准备时长。
也就是说，第二时长可以为前面的表1或者表2中的PUSCH准备时长N 2。举例来说，终端设备的能力为PUSCH处理能力2，当子载波间隔为15kHz时，第二时长为5个符号。
实施例一中，第一时长可以是指在配置第一配置信息时的PUSCH准备时长。也就是说，本申请实施例中，每个PUSCH处理能力1有2种类型的PUSCH准备时长，当网络设备没有向终端设备发送第一配置信息时，终端设备使用现有技术中的表1或表2中的PUSCH准备时长，即第二时长；当网络设备向终端设备发送第一配置信息时，终端设备使用的PUSCH准备时长为第一时长，从而实现增大DCI到CG PUSCH之间的间隔，同时DCI到DG PUSCH的间隔也增大了。这样可以使得物理层准备发送的PUSCH和MAC层递的PDU对应的PUSCH不一致时，物理层能够有足够的时间去取消准备发送的PUSCH，去准备发另外一个PUSCH，避免把两个PUSCH都丢弃，以提高传输性能。
本申请实施例中，第一时长可以存在多种实现方式。例如在方式一中，第一时长可以等于第二时长与预设时长之和，预设时长大于0。例如预设时长可以为1个符号或者2个符号或者3个符号等。预设时长可以是终端设备上报的值或者预设值。
在该实现方式中，可以将前面的表1替换为下面的表3，将表2替换为下面的表4。
在PUSCH处理能力1下PUSCH准备时长可以如表3所示。
表3
μ 第一时长(PUSCH准备时长)
0 10+Δ
1 12+Δ
2 23+Δ
3 36+Δ
在PUSCH处理能力2下PUSCH准备时长可以如表4所示。
表4
μ 第一时长(PUSCH准备时长)
0 5+Δ
1 5.5+Δ
2 11+Δ(对应频率范围1)
其中，Δ表示预设时长。
需要说明的是，表3和表4中，以每个子载波间隔下，即μ不同时对应的预设时长Δ相同为例进行描述。在实际应用中，不同的子载波间隔，即μ不同时对应的预设时长Δ的值也可以不同。
另一种实现方式中，在配置第一配置信息时，可以重新定义一个大于PUSCH准备时长的时长，即第一时长，或者称为增强PUSCH准备时长。在该实现方式中，可以将前面的表1替换为下面的表5，将表2替换为下面的表6。
在PUSCH处理能力1下PUSCH准备时长可以如表5所示。
表5
μ 第一时长N 3(PUSCH准备时长)
0 >10
1 >12
2 >23
3 >36
在PUSCH处理能力2下PUSCH准备时长可以如表6所示。
表6
μ 第一时长N 3(PUSCH准备时长)
0 >5
1 >5.5
2 >11(对应频率范围1)
其中，第一时长的具体取值，可以为预设值，也可以为终端设备上报的值。
在方式二中，终端设备配置为PUSCH处理能力2时，第一时长可以等于PUSCH处理能力1对应的PUSCH准备时长。也就是说，将PUSCH处理能力1对应的PUSCH准备时长，作为PUSCH处理能力2对应的PUSCH准备时长。
其中，终端设备配置为PUSCH处理能力1时，PUSCH准备时长可以保持表1中的取值不变，也可以采用上面表3的实现方式实现。
举例来说，终端设备配置为PUSCH处理能力2时，在PUSCH处理能力2下PUSCH 准备时长(即第一时长)可以如表7所示。
表7
μ 第一时长(PUSCH准备时长)
0 10
1 12
2 23(对应频率范围1)
另外，第一下行控制信息与第一物理上行信道之间的间隔可以大于或等于第三时长，所述第三时长大于第四时长。第四时长可以根据前面的公式(1)确定。
本申请实施例中，第三时长可以根据第一时长确定。举例来说，可以将公式(1)中的N 2替换为第一时长，从而获得第三时长，具体的，第三时长T 2可以满足以下形式：
T 2＝max((N 3+d 2,1+d 2)(2048+144)·κ2 -μ·T C+T ext+T switch,d 2,2)···(4)
其中，N 3可以表示第一时长。公式(4)中的其他参数可以参考前面的描述，在此不再赘述。
需要说明的是，如果第一时长N 3等于第二时长与预设时长之和，即第一时长N 3等于N 2+Δ 2，那么第三时长T 2还可以满足以下形式：
T 2＝max((N 2+Δ 2+d 2,1+d 2)(2048+144)·κ2 -μ·T C+T ext+T switch,d 2,2)···(5)
其中，Δ 2是终端设备上报的值或者预设值。公式(5)中的其他参数可以参考前面的描述，在此不再赘述。
需要说明的是，本申请实施例中，如果网络设备没有向终端设备发送第一配置信息。此时可以按照现有技术中的方式确定第一下行控制信息与第一物理上行信道之间的间隔，即按照前面的公式(1)确定。或者，还可以按照实施例一中的方式确定第一下行控制信息与第一物理上行信道之间的间隔，本申请并不限定。也就是说，第一下行控制信息与所述第二物理上行信道之间的间隔，可以大于或等于第一时长，也可以大于或等于第二时长，本申请并不限定。
实施例二：第二物理上行信道为配置授权PUSCH。
在实施例二中，不论网络设备是否向终端设备发送第一配置信息，均保持现有技术中的PUSCH准备时长不变，即保持表1和表2中的PUSCH准备时长不变。
在实施例二中，可以在公式(1)中增加一个第一指定时长d 3，从而实现增加第一下行控制信息与第一物理上行信道之间的间隔。具体的，第一下行控制信息与第一物理上行信道之间的间隔可以大于或等于第三时长，第三时长T 2可以满足以下形式：
T 2＝max((N 2+d 2,1+d 2+d 3)(2048+144)·κ2 -μ·T C+T ext+T switch,d 2,2)···(6)
需要说明的是，第一指定时长可以等于前面的预设时长，也可以不等于该预设时长。第一指定时长的具体取值，可以为预设值，也可以为终端设备上报的值。
另外，如果第一物理上行信道和第二物理上行信道在时域上重叠，第一下行控制信息与第二物理上行信道之间的间隔可以大于或等于PUSCH准备时长与预设时长之和。该 PUSCH准备时长，可以是指表1或表2中的PUSCH准备时长，或者可以是指前面描述的第二时长。
实施例三：第二物理上行信道为PUCCH。
可选地，第二物理上行信道中承载的第二信息可以为SR。
场景三，网络设备向终端设备发送了第一配置信息。
可选的，一种场景中，如果第一物理上行信道和第二物理上行信道在时域上重叠，第一下行控制信息与第二物理上行信道之间的间隔大于或等于第一时长。第一时长大于第二时长，第二时长为根据所述PUSCH准备时长确定的时长。
可选的，另一种场景中，第二物理上行信道为PUSCH时，所述第一物理上行信道的起始时刻位于第二物理上行信道的起始时刻之后时，如果第一物理上行信道和第二物理上行信道在时域上重叠，第一下行控制信息与第二物理上行信道之间的间隔大于或等于第一时长。
具体的，第二时长可以是根据公式(2)和公式(3)确定的
Figure PCTCN2021140714-appb-000025
一种可能的实现方式中，第一时长T 1满足以下形式：
Figure PCTCN2021140714-appb-000026
Figure PCTCN2021140714-appb-000027
其中，N 3是大于PUSCH准备时长的值。例如N 3可以称为增强PUSCH准备时长。
一种场景中，每个PUSCH处理能力1配置了2种类型的PUSCH准备时长，当网络设备没有向终端设备发送第一配置信息时，终端设备使用现有技术中的表1或表2中的PUSCH准备时长，即第二时长；当网络设备向终端设备发送第一配置信息时，终端设备使用的PUSCH准备时长为增强PUSCH准备时长，从而实现增大DCI到PUSCH之间的间隔，同时也增大了DCI到PUCCH之间的间隔。这样可以使得物理层准备发送的PUSCH而MAC层递的是SR时，物理层能够有足够的时间去取消准备发送的PUSCH，去准备发SR，避免都丢弃，以提高传输性能。
增强PUSCH准备时长可以等于第二时长与第二指定时长之和，第二指定时长可以是指前面的预设时长，也可以是指其他大于0的时长。第二指定时长的具体取值，可以为预设值，也可以为终端设备上报的值。
例如，可以将前面的表1替换为下面的表8，将表2替换为下面的表9。
在PUSCH处理能力1下PUSCH准备时长可以如表8所示。
表8
μ 增强PUSCH准备时长
0 10+Δ 3
1 12+Δ 3
2 23+Δ 3
3 36+Δ 3
在PUSCH处理能力2下PUSCH准备时长可以如表9所示。
表9
μ 增强PUSCH准备时长
0 5+Δ 3
1 5.5+Δ 3
2 11+Δ 3(对应频率范围1)
其中，Δ 3表示第二指定时长。
一种场景中，终端设备配置为PUSCH处理能力2时，增强PUSCH准备时长可以等于PUSCH处理能力1对应的PUSCH准备时长。也就是说，将PUSCH处理能力1对应的PUSCH准备时长，作为PUSCH处理能力2对应的PUSCH准备时长。
另一种可能的实现方式中，不论网络设备是否向终端设备发送第一配置信息，均保持现有技术中的PUSCH准备时长不变，即保持表1和表2中的PUSCH准备时长不变。
在实施例三中，可以在公式(3)中增加一个第三指定时长Δ1，从而实现增加第一下行控制信息与第二物理上行信道之间的间隔。具体的，第一时长T 1可以满足以下形式：
Figure PCTCN2021140714-appb-000028
Figure PCTCN2021140714-appb-000029
第三指定时长可以是指前面的预设时长，也可以是指其他大于0的时长。第三指定时长的具体取值，可以为预设值，也可以为终端设备上报的值。
可选的，另一种可能的实现方式中，第二物理上行信道为PUSCH时，所述第一物理上行信道的起始时刻位于第二物理上行信道的起始时刻之前，所述第一下行控制信息与第一物理上行信道之间的间隔大于或等于第三时长，第三时长T 2满足以下形式：
T 2＝max((N 2+Δ 2+d 2,1+d 2)(2048+144)·κ2 -μ ·T C+T ext+T switch,d 2,2)···(11)
其中，Δ 2是终端设备上报的值或者预设值。
或者，第三时长T 2满足以下形式：
T 2＝max((N 3+d 2,1+d 2)(2048+144)·κ2 -μ·T C+T ext+T switch,d 2,2)···(12)
其中，N 3是大于N 2的值，N 3是终端设备上报的值或者预设值。
