Description

通信方法及设备

技术领域
本申请涉及移动通信技术领域，尤其涉及一种通信方法及设备。
背景技术
在现有的通信系统中，时分双工(Time Division Duplex，TDD)系统相较于频分双工(Frequency Division Duplex，FDD)系统，会带来业务调度时延的增加。为了解决TDD系统带来的时延问题，一种可能的方式是引入子带全双工，即将工作带宽细分为多个子带，并灵活配置各子带的上下行配比。
现有的TDD系统中，网络设备或终端设备通过判断符号(symbol)的上下行方向来确定物理信道是否有效，从而决定是否进行发送或接收。
然而，在全双工场景下，若网络设备或终端设备仍根据符号的上下行方向来确定物理信道是否有效，会导致下行符号中的上行子带无法用于上行发送，以及上行符号中的下行子带也无法用于上行发送，从而限制了业务调度的灵活性。

参照图1，图1为本申请实施例中提供的一种无线通信系统的架构示意图。本实施例提供的无线通信系统包括终端设备101和网络设备102。
可选的，终端设备101可以为各种形式的用户设备(User Equipment，UE)、接入终端、用户单元、用户站、移动站、移动台(mobile station，MS)、远方站、远程终端、移动设备、无线通信设备、用户代理或用户装置。还可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、掌上电脑(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network，PLMN)中的终端设备等，本申请实施例对此并不限定，只要该终端设备能够与网络设备102无线通信即可。
可选的，网络设备102即公用移动通信网络设备，是终端设备101接入互联网的接口设备，也是无线电台站的一种形式，是指在一定的无线电覆盖区中，与终端设备之间进行信息传递的无线电收发信电台，包括基站(Base Station，BS)，也可称为基站设备，是一种部署在无线接入网(Radio Access Network，RAN)用以提供无线通信功能的装置。例如在2G网络中提供基站功能的设备包括基地无线收发站(Base Transceiver Station，BTS)，3G网络中提供基站功能的设备包括节点B(NodeB)，在4G网络中提供基站功能的设备包括演进的节点B(evolved NodeB，eNB)，在无线局域网络(Wireless Local Area Networks，WLAN)中，提供基站功能的设备为接入点(Access Point，AP)，5G NR中的提供基站功能的设备gNB，以及继续演进的节点B(ng-eNB),其中gNB和终端设备之间采用NR技术进行通信，ng-eNB和终端设备之间采用演进的通用陆地无线接入网络(Evolved Universal Terrestrial Radio Access，E-UTRA)技术进行通信，gNB和ng-eNB均可连接到5G核心网。本申请实施例中的网络设备103还包含在未来新的通信系统中提供基站功能的设备等。
本申请实施例定义接入网到终端设备的单向通信链路为下行链路(Downlink，DL)，在下行链路上传输的数据为下行数据，下行数据的传输方向称为下行方向；而终端设备到接入网的单向通信链路为上行链路(Uplink，UL)，在上行链路上传输的数据为上行数据，上行数据的传输方向称为上行方向。
在传统的TDD系统中，上下行时隙配比是宽带的，即整个工作带宽在每个时隙是上行或下行。当一个时隙是下行时，则无法用于发送上行数据，反之亦然。因此，与FDD系统相比，传统的TDD系统会带来业务调度时延的增加。
为了克服传统的TDD系统带来的时延问题，一种可能的方式是引入子带全双工，即将工作带宽细分为多个子带，并灵活配置各子带的上下行配比。
为了更好的理解本申请实施例，参照图2a至图2d，图2a至图2d为本申请实施例提供的几种传输资源配置示意图。
在2a至图2d中，“D”表示下行子带，“U”表示上行子带。
其中，基站将频域资源分为不同的子带，不同子带上同时分别进行下行发送和上行接收，对于终端设备而言，仍然支持半双工，在某个时间点只能在下行子带进行下行接收，或者在上行子带进行上行发送。
现有标准中，网络设备和终端设备通过判断符号的上下行方向来确定物理信道或参考信号是否有效，从而决定是否进行发送或接收，例如：
一、网络设备向终端设备调度一个或多个PUSCH时，对于每个PUSCH发送时机，若其占用的符号的其中之一为下行符号，则该PUSCH发送时机是一个无效的PUSCH发送时机。
相应的，当网络设备向终端设备调度多个PUSCH时，调度信息中的混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)进程标识(ID)(以下简称为HARQ process ID)应用于第一个有效的PUSCH发送时机，且HARQ process ID仅对有效的PUSCH发送时机进行递增。
二、网络设备向终端设备调度一个或多个PDSCH时，对于每个PDSCH发送时机，若其占用的符号的其中之一为上行符号，则该PDSCH发送时机是一个无效的PDSCH发送时机。
相应的，当网络设备向终端设备调度多个PDSCH时，调度信息中的HARQ process ID应用于第一个有效的PDSCH发送时机，且HARQ process ID仅针对有效的PDSCH发送时机进行递增。
三、网络设备向终端设备配置PDCCH时，对于每一个PDCCH候选，若其占用的符号的其中之一为上行符号，则该PDCCH候选是一个无效的PDCCH候选。
四、网络设备向终端设备调度一个或多个PUCCH时，对于被调度的PUCCH发送时机，若其占用的符号的其中之一为下行符号，则该PUCCH发送时机是一个无效的PUCCH发送时机。
五、网络设备向终端设备发送下行接收抢占指示信息时，指示的符号中不包含上行符号。
六、网络设备向终端设备发送上行发送取消指示信息时，指示的符号中不包含下行符号。
然而，在全双工场景下，若网络设备和终端设备仍根据符号的上下行方向来确定物理信道或参考信号是否有效，会导致下行符号中的上行子带无法用于上行发送，上行符号中的下行子带也无法用于上行发送，从而限制了调度的灵活性。
面对上述技术问题，本申请实施例提供了一种通信方法及设备，网络设备和终端设备可以根据物理信道占用的时频资源中的PRB，来确定物理信道是否属于有效物理信道，从而能够避免下行符号中的上行子带无法用于上行发送，以及上行符号中的下行子带无法用于上行发送的情况出现，不仅能够提升业务调度的灵活性，还能够降低调度时延。下面采用详细的实施例进行详细说明。
参照图3，图3为本申请实施例提供的一种通信方法的流程示意图一。

在一些实施例中，网络设备可以向终端设备发送第一信息，该第一信息中包括至 少一个物理信道的时频资源信息或调度信息。
网络设备根据上述每个物理信道占用的时频资源中的PRB的上下行方向，来确定每个物理信道是否属于有效物理信道。
示例性的，对于物理下行信道而言，若其占用的时频资源中存在上行PRB，则可以确定该物理下行信道属于无效物理信道；若其占用的时频资源中不存在上行PRB，则可以确定该物理下行信道属于有效物理信道。
对于物理上行信道而言，若其占用的时频资源中存在下行PRB，则可以确定该物理上行信道属于无效物理信道；若其占用的时频资源中不存在下行PRB，则可以确定该物理上行信道属于有效物理信道。
S302、若所述物理信道属于有效物理信道，则向终端设备传输所述物理信道。
在一些实施例中，在网络设备确定出每个物理信道是否有效之后，只需要向终端设备传输各个有效物理信道，而无需向终端设备传输有效物理信道。
可以理解的是，本申请实施例中是基于物理信道占用的时频资源中的PRB的上下行方向，来确定物理信道是否属于有效物理信道，相较于传统的根据符号的上下行方向来确定物理信道是否属于有效物理信道的方式，本申请实施例可以实现利用下行符号中的上行子带进行上行发送，以及利用上行符号中的下行子带进行上行发送。

在一些实施例中，当上述第一信息调度多个PUSCH时，上述调度信息中的HARQ process ID应用于第一个有效的PUSCH发送时机，且该HARQ process ID仅对有效的PUSCH发送时机进行递增。
