Description

一种通信方法及装置 技术领域
本申请涉及无线通信技术领域，特别涉及一种通信方法及装置。
背景技术
长期演进(long term evolution，LTE)系统中，基站使用终端设备发送的上行探测参考信号(sounding reference signal，SRS)来估计上行信道质量。SRS还可用于估计上行定时(timing)等。终端设备发送的SRS一般位于上行子帧的最后一个符号上。但由于现有的上下行子帧配比中，上行子帧比例较少，导致能够发送SRS的符号数较少，极大的限制了SRS的容量。
基于SRS的重要性，在未来的R16版本的LTE中，基站可以配置终端设备在上行子帧中使用多个符号发送SRS，从而可以提升SRS的容量和覆盖。然而，当终端设备使用多个符号发送SRS时，会与终端设备在该上行子帧中发送的物理上行控制信道(physical uplink control channel，PUCCH)占用的资源发生冲突。因为PUCCH在上行子帧中需要占用14个符号或13个符号。在SRS占用1个符号时，PUCCH可以占用13个符号；在SRS占用至少2个符号时，终端设备如何发送PUCCH，是一个亟待解决的问题。
发明内容

通过上述方法，在SRS占用至少两个符号的情况下，通过发送缩短模式的PUCCH，可以避免PUCCH和SRS的发送冲突，从而可以同时发送SRS以及PUCCH。

一种可能的设计中，所述终端设备采用第一传输功率发送所述PUCCH；所述第一传输功率大于第二传输功率；所述第二传输功率为，所述终端设备发送常规模式的PUCCH或截断模式的PUCCH所采用的功率。
通过上述方法，采用缩短模式的PUCCH时，增加PUCCH的传输功率，可以提升PUCCH的覆盖范围，最终使得在PUCCH占用的符号数减少的情况下，不降低PUCCH的覆盖性能。

本申请实施例中，终端设备，可以为具有无线收发功能的设备或可设置于任一设备中的芯片，也可以称为用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、无线通信设备、用户代理或用户装置。本申请实施例中的终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端、增强现实(augmented reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。
网络设备，为具有无线收发功能的设备或可设置于该设备的芯片，该网络设备可用于将收到的空中帧与IP分组进行相互转换，作为终端设备与接入网的其余部分之间的路由器，还可用于协调对空中接口的属性管理。该设备包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(baseband unit，BBU)，无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission and reception point，TRP或者transmission point，TP)等，还可以为5G(NR)系统中的gNB或传输点(TRP或TP)，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点等。
结合前面的描述，如图1所示，为本申请实施例提供的一种通信方法流程示意图。参见图1，该方法包括：
步骤101：终端设备确定上行子帧；所述上行子帧包括SRS以及PUCCH时，所述SRS占用至少两个符号，所述PUCCH为缩短模式的PUCCH。
需要说明的是，本申请实施例中，符号可以是指单载波频分多址(single-carrier frequency-division multiple access，SC-FDMA)符号，也可以是指正交频分多址(orthogonal frequency-division multiple access，OFDMA)符号等，具体可以根据实际情况确定，在此不再赘述。
本申请实施例中，缩短模式的PUCCH占用的符号数小于13，具体的，缩短模式的PUCCH占用的符号数小于或等于所述上行子帧包括的符号数与所述SRS占用的符号数的差值。
举例来说，缩短模式的PUCCH可以为短物理下行控制信道(short phy sical uplink control channel，SPUCCH)，SPUCCH包括但不限于slot-SPUCCH，以及subslot-SPUCCH等。
步骤102：所述终端设备发送所述上行子帧。
所述终端设备发送上行子帧，可以是指终端设备通过上行子帧发送SRS以及PUCCH等信息。
步骤103：网络设备接收来自终端设备的上行子帧。
步骤104：所述网络设备根据所述上行子帧中的SRS进行信道估计，并根据所述PUCCH确定上行控制信息。
步骤104中，网络设备具体如何根据SRS进行信道估计，以及根据PUCCH确定上行控制信息，本申请实施例对此并不限定，具体可以参考现有的LTE系统等中的描述，在此不再赘述。
步骤101中，终端设备可以根据SRS占用的符号数，确定PUCCH的模式。具体的，SRS占用至少两个符号，则所述PUCCH的模式为缩短模式的PUCCH；若所述SRS占用一个符号，则所述PUCCH的模式为常规模式的PUCCH或截断模式的PUCCH。其中，SRS占用一个符号时，所述SRS可以占用所述上行子帧中的最后一个符号。
本申请实施例中，常规模式的PUCCH占用14个符号，截断模式的PUCCH占用13个符号。而相对于常规模式的PUCCH或截断模式的PUCCH，缩短模式的PUCCH占用较少的符号数，缩短模式的PUCCH占用的符号数可以位于1至12之间。例如，缩短模式的PUCCH为SPUCCH时，一般占用的符号数为7个或者2个或者3个，因此当SPUCCH与SRS在一个上行子帧中发送时，可以避免SPUCCH和SRS占用的符号发送的冲突，导致无法发送SPUCCH的问题。
进一步的，步骤102中，PUCCH为缩短模式的PUCCH时，终端设备可以通过提高PUCCH的传输功率来提升PUCCH的覆盖范围。具体的，PUCCH为缩短模式的PUCCH时，所述终端设备采用第一传输功率发送所述PUCCH；所述第一传输功率大于第二传输功率；所述第二传输功率为，所述终端设备发送常规模式的PUCCH或截断模式的PUCCH所采用的功率。第二传输功率可以通过现有的公式计算，在此不再赘述。第一传输功率可以为大于第二传输功率的任意值，也可以通过其他方式确定，下面将根据不同情况分别进行描述。
第一种可能的实现方式中，终端设备使用两个码道来发送PUCCH，两个码道分布在连续的两个RB上，并通过提高PUCCH的传输功率来提升PUCCH的覆盖范围，下面将 详细描述。
当终端设备发送的PUCCH为缩短模式的PUCCH时，固定使用两个码道来发送PUCCH，两个码道分布在连续的两个资源块(resource block，RB)上。此时，PUCCH占用两个RB，所述PUCCH占用的两个RB位于同一个时隙，且在频域上相邻，即在频域上连续。举例来说，PUCCH为缩短模式的PUCCH时，PUCCH占用的RB可以如图2所示。图2中，PUCCH占用的两个RB位于同一个时隙，且在频域上相邻。
本申请实施例中，PUCCH为缩短模式的PUCCH时，如何实现为PUCCH分配两个在频域上连续的RB，可以存在多种方式，下面分不同情况讨论。
第一种情况：PUCCH的格式(format)为PUCCH format 1/1a/1b
此时，可以通过以下公式确定PUCCH占用的两个资源的索引：

分别是PUCCH占用的两个资源的资源索引，为描述方便采用同一标号表示。通过每个资源索引，能够得到该资源索引指示的资源所在的RB，所使用的循环移位(cyclic shift)和正交序列(orthogonal sequence)。
通过上述公式(1)和公式(2)，可以实现为PUCCH分配两个RB，且分配的RB在频域上连续。
公式(1)和公式(2)中，

则不存在混合PUCCH。一个子帧中至多只有一个RB可用于传输混合PUCCH。

是通过小区级的配置参数来配置的。
Figure PCTCN2018106773-appb-000015
为PUCCH format 1/1a/1b的RB内可用的循环移位(cyclic shift)的个数，可用由网络侧配置；

第二种情况：PUCCH的格式为PUCCH format 2/2a/2b
在该情况下，网络侧可用通过高层信令配置一个资源索引，该资源索引记为
Figure PCTCN2018106773-appb-000017
本申请实施例中，在网络侧配置的资源索引基础上，还要分配一个资源索引，该资源索引可用表示如下：
Figure PCTCN2018106773-appb-000018
通过上述方式，可以在网络侧分配的RB的基础上，将该RB相邻的RB分配给PUCCH，从而实现为PUCCH分配两个RB，且分配的RB在频域上连续。
第三种情况：PUCCH的格式为PUCCH format 3
在该情况下，网络侧可用通过高层信令配置一个资源索引，该资源索引记为
Figure PCTCN2018106773-appb-000019
本申请实施例中，在网络侧配置的资源索引基础上，还要分配一个资源索引，该资源索引可用表示如下：

其中，

通过上述方式，可以在网络侧分配的RB的基础上，将该RB相邻的RB分配给PUCCH， 从而实现为PUCCH分配两个RB，且分配的RB在频域上连续。
在第一种可能的实现方式中，在终端设备使用两个码道来发送PUCCH，两个码道分布在连续的两个RB上时，终端设备发送的PUCCH，在第i个上行子帧内的传输功率P PUCCH(i)可以满足以下公式：
Figure PCTCN2018106773-appb-000022
其中：i为自然数，
Figure PCTCN2018106773-appb-000023
为取A和B中的最小值运算，P CMAX,c(i)为网络侧配置的所述终端设备的最大传输功率，P 0_PUCCH为网络设备通过高层信令配置的功率基准值，PL c为所述终端设备在小区c中确定的路径损耗值，h(n CQI,n HARQ,n SR)为根据所述PUCCH中所承载的信道质量信息和应答响应比特数确定的功率偏置，M PUCCH,c(i)为所述PUCCH占用的资源块的数量，Δ F_PUCCH(F)为网络设备通过高层信令配置的与物理上行控制信道格式相关的参数，Δ TxD(F′)为根据所述PUCCH的调整编码方式和数据类型确定的功率偏置，g(i)为所述终端设备的闭环功率控制的调整值。
上述方法中，在SRS占用的符号数增加的情况下，为了避免PUCCH和SRS的发送冲突，通过将PUCCH的发送的符号数减少，即采用SPUCCH，但同时增加PUCCH的码道数及RB数，再通过提高PUCCH的传输功率，可以提升PUCCH的覆盖范围，最终使得在PUCCH占用的符号数减少的情况下，不降低PUCCH的覆盖性能。
第二种可能的实现方式中，PUCCH为缩短模式的PUCCH时，终端设备在发送PUCCH时，可以不通过增加PUCCH的码道和RB数，而是直接提高PUCCH的传输功率来提升PUCCH的覆盖范围，下面将详细描述。
方式一：通过在现有的计算PUCCH的传输功率的公式中，增加一个参数Δ S_PUCCH(F)，当所述PUCCH为缩短模式的PUCCH，例如为SPUCCH时，Δ S_PUCCH(F)为大于0的预设值，当所述PUCCH为常规模式的PUCCH或截断模式的PUCCH时，Δ S_PUCCH(F)等于0。例如当所述PUCCH为缩短模式的PUCCH时，Δ S_PUCCH(F)的取值为3，这样就可以将PUCCH的传输功率提升3dB，从而可以补偿PUCCH由于符号数减少带来的性能损失。
具体的，所述PUCCH为缩短模式的PUCCH时，所述PUCCH在第i个上行子帧内的传输功率P PUCCH(i)满足以下公式：
Figure PCTCN2018106773-appb-000024
其中：i为自然数，
Figure PCTCN2018106773-appb-000025
为取A和B中的最小值运算，P CMAX,c(i)为网络侧配置的所述终端设备的最大传输功率，P 0_PUCCH为网络设备通过高层信令配置的功率基准值，PL c为所述终端设备确定的路径损耗值，h(n CQI,n HARQ,n SR)为根据所述PUCCH中所承载的信 道质量信息和应答响应比特数确定的功率偏置，Δ F_PUCCH(F)为网络设备通过高层信令配置的与物理上行控制信道格式相关的参数，g(i)为所述终端设备的闭环功率控制的调整值；Δ TxD(F′)为根据所述PUCCH的调整编码方式和数据类型确定的功率偏置。
方式二：通过将现有的计算PUCCH的传输功率的公式中的一个参数进行复用，将该参数配置两个值，一个值为现有的用于计算PUCCH的传输功率所采用的值，另一个值大于现有的用于计算PUCCH的传输功率所采用的值。当所述PUCCH为缩短模式的PUCCH时，取上述两个值中的较大值；当所述PUCCH为常规模式的PUCCH或截断模式的PUCCH时，取上述两个值中的较小值，从而可以补偿PUCCH由于符号数减少带来的性能损失。
举例来说，可以为Δ TxD(F′)配置两个值，当所述PUCCH为缩短模式的PUCCH时，Δ TxD(F′)为第一值，当所述PUCCH为常规模式的PUCCH或截断模式的PUCCH时，Δ TxD(F′)为第二值，所述第二值为根据所述PUCCH的调整编码方式和数据类型确定的功率偏置，即现有的用于计算PUCCH的传输功率所采用的值，所述第一值大于所述第二值。例如，第一值比第二值大3dB。
此时，在所述PUCCH为缩短模式的PUCCH，例如SPUCCH时，所述PUCCH在第i个上行子帧内的传输功率P PUCCH(i)可以满足以下公式：
Figure PCTCN2018106773-appb-000026
其中：i为自然数，
Figure PCTCN2018106773-appb-000027
为取A和B中的最小值运算，P CMAX,c(i)为网络侧配置的所述终端设备的最大传输功率，P 0_PUCCH为网络设备通过高层信令配置的功率基准值，PL c为所述终端设备确定的路径损耗值，h(n CQI,n HARQ,n SR)为根据所述PUCCH中所承载的信道质量信息和应答响应比特数确定的功率偏置，Δ F_PUCCH(F)为网络设备通过高层信令配置的与物理上行控制信道格式相关的参数，g(i)为所述终端设备的闭环功率控制的调整值；当所述PUCCH为缩短模式的PUCCH时，Δ TxD(F′)为第一值，当所述PUCCH为常规模式的PUCCH或截断模式的PUCCH时，Δ TxD(F′)为第二值。
通过上述方法，在SRS占用的符号数增加的情况下，为了避免PUCCH和SRS的发送冲突，通过将PUCCH的发送的符号数减少，例如采用SPUCCH，但同时增加PUCCH的传输功率，可以提升PUCCH的覆盖范围，最终使得在PUCCH占用的符号数减少的情况下，不降低PUCCH的覆盖性能。
