Description

指示信息的上报和接收方法以及装置 技术领域
本申请实施例涉及通信技术领域。
背景技术
目前,新无线(NR,New Radio)系统可以在以下两个频率范围内的频段(包括FR1和FR2)上工作,但还不支持在更高频段工作。
Figure PCTCN2021071958-appb-000001
为此,3GPP在Rel-17的标准化工作中将研究如何支持NR在更高频段(例如,在52.6-71GHz的频率范围内的频段)工作。上述更高频段范围包括非授权(或共享)频段。
在非授权(或共享)频段,一般地,发送设备在发送之前需要进行信道检测(channel sensing),在检测到信道为空闲时才能发送,该机制例如称为LBT(Listen Before Talk)。这一方面是为了保护其他设备正在进行的传输,避免造成干扰;另一方面也是为了确定接收设备没有受到干扰,能够正确地接收。
应该注意,上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明,并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
但是,发明人发现:由于发送设备的周围环境与接收设备不同,发送设备检测到的能量或者说干扰和接收设备的实际情况可能并不相同。例如,可能会存在隐藏节点(发送设备没有检测到、但对接收设备造成了干扰的干扰源)和暴露节点(发送设备检测到、但没有对接收设备造成干扰的干扰源)。而在高频,由于波束赋形和路损的影响,隐藏节点和暴露节点的问题相对低频可能更为严重。
针对上述问题的至少之一,本申请实施例提供一种指示信息的上报方法以及装置。
根据本申请实施例的一个方面,提供一种指示信息的上报装置,包括:
测量单元,其采用第一空间参数在第一资源上进行测量;
发送单元,其采用第二空间参数在第二资源上向网络设备发送用于承载指示信息的上行传输,所述指示信息用于上报所述测量的测量结果。
根据本申请实施例的另一个方面,提供一种指示信息的上报方法,包括:
终端设备采用第一空间参数在第一资源上进行测量;
所述终端设备采用第二空间参数在第二资源上向网络设备发送用于承载指示信息的上行传输,所述指示信息用于上报所述测量的测量结果。
根据本申请实施例的另一个方面,提供一种指示信息的接收装置,包括:
接收单元,其接收终端设备采用第二空间参数在第二资源上发送的用于承载指示信息的上行传输,所述指示信息用于上报所述终端设备采用第一空间参数在第一资源上进行的测量的结果。
根据本申请实施例的另一个方面,提供一种指示信息的接收方法,包括:
网络设备接收终端设备采用第二空间参数在第二资源上发送的用于承载指示信息的上行传输,所述指示信息用于上报所述终端设备采用第一空间参数在第一资源上进行的测量的结果。
本申请实施例的有益效果之一在于:终端设备采用第一空间参数在第一资源上进行测量;向网络设备发送用于承载指示信息的上行传输,所述指示信息用于上报所述测量的测量结果。由此,网络设备能够及时准确地获知终端设备的干扰情况,进而采用适当的方式发送下行传输,使得终端设备能够正确地接收该下行传输。

针对一种实施方式描述和/或示出的特征可以以相同或类似的方式在一个或更多个其它实施方式中使用,与其它实施方式中的特征相组合,或替代其它实施方式中的特征。

在本申请实施例中,术语“网络设备”例如是指通信系统中将终端设备接入通信网络并为该终端设备提供服务的设备。网络设备可以包括但不限于如下设备:基站(BS,Base Station)、接入点(AP、Access Point)、发送接收点(TRP,Transmission Reception Point)、广播发射机、移动管理实体(MME、Mobile Management Entity)、网关、服务器、无线网络控制器(RNC,Radio Network Controller)、基站控制器(BSC,Base Station Controller)等等。
其中,基站可以包括但不限于:节点B(NodeB或NB)、演进节点B(eNodeB或eNB)以及5G基站(gNB),等等,此外还可包括远端无线头(RRH,Remote Radio Head)、远端无线单元(RRU,Remote Radio Unit)、中继(relay)或者低功率节点(例如femeto、pico等等)、IAB(Integrated Access and Backhaul)节点或IAB-DU或IAB-donor。并且术语“基站”可以包括它们的一些或所有功能,每个基站可以对特定的地理区域提供通信覆盖。术语“小区”可以指的是基站和/或其覆盖区域,这取决于使用该术语的上下文。在不引起混淆的情况下,术语“小区”和“基站”可以互换。
在本申请实施例中,术语“用户设备”(UE,User Equipment)或者“终端设备”(TE,Terminal Equipment或Terminal Device)例如是指通过网络设备接入通信网络并接收网络服务的设备。终端设备可以是固定的或移动的,并且也可以称为移动台(MS,Mobile Station)、终端、用户台(SS,Subscriber Station)、接入终端(AT,Access Terminal)、IAB-MT、站(station),等等。

在基站1进行信道检测时,虽然其他设备(例如其他基站、终端设备等)正使用波束2发送数据并且如果基站1采用波束1向终端设备发送数据将受到该其他设备造成的干扰,但由于该其他设备发送数据的方向与基站1进行信道检测的方向并不一致(甚至完全相反),基站1无法检测到该其他设备的存在。也就是说,基站1可能认为信道空闲并采用波束1向终端设备发送数据,而由于该其他设备的干扰,终端设备可能无法正确接收数据。

值得注意的是,以上附图3仅对本申请实施例进行了示意性说明,但本申请不限于此。例如可以适当地调整各个操作之间的执行顺序,此外还可以增加其他的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型,而不仅限于上述附图3的记载。
在一些实施例中,所述第一空间参数与用于接收第一参考信号和/或信道的空间参数相关,或者,所述第一空间参数与用于接收所述第一参考信号和/或信道的空间参数相同。即,终端设备采用用于接收第一参考信号和/或信道的空间参数在第一资源上进行测量。
在一些实施例中,所述第一资源与所述第一参考信号和/或信道具有准共址(QCL,Quasi Co-Location)关系。例如所述第一资源与所述第一参考信号和/或信道是QCL-TypeD的,或者是QCL-TypeD且是QCL-TypeA的,等等,关于QCL的具体内容可参考相关技术。
所述第一参考信号和/或信道例如为以下至少之一:用于触发所述终端设备上报所述测量的测量结果的下行传输;

例如,终端设备在第一资源上进行信道检测(LBT),若检测到的能量不超过用于判断信道是否空闲的阈值(也就是说,LBT结果为信道空闲),则发送上述上行传输,否则,不发送所述上行传输。
由此,终端设备可以向网络设备上报测量的测量结果。网络设备能够及时准确地获知终端设备的干扰情况,进而采用适当的方式发送下行传输,使得终端设备能够正确地接收该下行传输。
在一些实施例中,指示信息可以仅指示一个波束(或者说SSB/CSI-RS)对应的测量结果。例如指示该SSB/CSI-RS可用或者不可用,等等。这种情况下,网络设备可以根据是否接收到用于承载该指示信息的上行传输,来确定该波束对应的测量结果。

例如,可以只支持所述CG PUSCH同时承载UL-SCH数据和所述指示信息。也就是说,不支持如下情况:在CG PUSCH不承载UL-SCH的情况下,采用CG PUSCH发送该指示信息。
图4是本申请实施例的各种资源的时序关系的一示意图,如图4所示,用于测量的资源(第一资源)的时域位置在用于承载指示信息(上报测量的测量结果)的上行传输(第二资源)之前;该第二资源的时频位置与该第一资源的时频位置不同。
此外,如图4所示,该第一资源的时域位置与该第二资源的时域位置之间的间隔小于或等于最大时间间隔,并且大于或等于最小时间间隔。
在一些实施例中,终端设备接收网络设备发送的下行传输,所述下行传输用于触发所述终端设备上报所述测量的测量结果。
