Description

通信方法、终端和网络设备

背景技术
随着通信技术的不断发展，新无线(New Radio，NR)通信系统，如第五代移动通信系统(可以简称为5G)，不仅可以部署在低频段，如3GHz以下(包括3GHz)的频段，也可以部署在高频段，如6GHz以上(包括6GHz)的频段。
高频信号的固有特性，比如穿透力低、遇遮挡物信号衰落块，会导致高频信号存在较大的路径损耗。为了补偿高频信号的路径损耗，提高业务的传输可靠性，通常情况下，高频系统在一个小区中会配置多个波束，并进行波束扫描，以保证覆盖。
高频系统中，终端也可以进行最小路测(minimization of drive-tests，MDT)，以获取网络相关参数，从而检测网络故障和/或优化网络性能。
但使用现有的MDT方法进行测量，终端的能耗较大。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
图1是能够应用本申请实施例的通信方法的通信系统的示意性架构图。应理解，本申请实施例并不限于图1所示的系统架构中，此外，图1中的装置可以是硬件，也可以是从功能上划分的软件或者以上二者的结合。
图1所示的通信系统包括一个或多个终端110，以及一个或多个网络设备120。终端110与网络设备120之间可以互相通信。具体地，网络设备120与终端110之间可以通过波束扫描方式进行通信。
终端110可以是用户设备(user equipment，UE)。UE可以经无线接入网(radio access network，RAN)与一个或多个核心网(core network，CN)进行通信。UE可称为接入终端、终端设备、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、无线网络设备、用户代理或用户装置。UE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、个人数字处理(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设备、车载设备、可穿戴设备或物联网、车辆网中的终端设备以及未来网络中的任意形态的终端设备等。
网络设备120的一种示例是基站。应理解，本申请实施例对基站的具体类型不作限定。采用不同无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同。为方便描述，本申请所有实施例中，上述为终端提供无线通信功能的装置统称为基站，
基站(base station，BS)，也可称为基站设备，是一种将终端接入到无线网络的设备，包括但不限于：传输接收点(transmission reception point，TRP)、5G节点B(gNB)、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(base band unit，BBU)，或Wifi接入点(access point，AP)，或小基站设备(pico)等。
图1所示的通信系统中，终端110可以进行信号测量，如终端110可以测量服务小区的信号，并向网络设备120上报测量结果，以便于网络管理设备根据测量结果检测网络中 的问题和故障，和/或优化网络性能。
目前终端的通信方法主要包括以下步骤：网络设备向终端发送测量配置信息，测量配置信息可以包括记录周期(如logging duration)、记录时长(如logging interval)等至少一种信息；终端根据测量配置信息进行测量，并上报测量结果；网络设备接收测量结果，然后可以根据该测量结果进行故障检测或网络优化等操作，或者，网络设备可以将测量结果发送给网络管理设备，由网络管理设备根据该测量结果进行故障检测或网络优化等操作。
其中，记录时长也可以称为记录间隔。
上述通信方法有如下缺点：网络设备通过测量配置信息指示的记录时长内，终端有可能检测不到信号，更谈不上对信号进行测量，此时，若终端一直执行信号测量流程，则会浪费终端的能耗。
因此本申请提出一种新的通信方法，以便于可以节省终端的能耗。
图2是本申请一个实施例的通信方法的示意性流程图。应理解，图2示出了通信方法的步骤或操作，但这些步骤或操作仅是示例，本申请实施例还可以执行其他操作或者图2中的各个操作的变形。
S210，终端根据小区的波束扫描方式进行信号测量，得到测量结果。其中，该小区可以是终端的服务小区。
波束扫描方式可以是小区的网络设备通过广播消息，或专有的RRC信令发送的，比如通过RRC测量配置信令发送。或者，终端还可以向小区的网络设备发送请求消息，请求小区的波束扫描方式，并接收小区的网络设备根据该请求消息发送的波束扫描方式。
波束扫描方式可以包括各个波束标识信息和对应的扫描时间的映射关系，和/或波束扫描周期。波束标识信息用于唯一识别波束，包括：波束的标识、波束的天线端口标识、波束的参考信号、波束的索引中的至少一个。
本申请实施例中波束英文可称为beam。
例如，发射波束可以是指信号经天线发射出去后在空间不同方向上形成的信号强度的分布，接收波束可以是指从天线上接收到的无线信号在空间不同方向上的信号强度分布。可以理解的是，一个波束的一个或多个天线端口也可以看作是一个天线端口集，也就是说一个天线端口集包括至少一个天线端口。
具体的，波束可以是指具有一定能量传输指向性的预编码向量并且能够通过索引信息去标识该预编码向量，能量传输指向性是指在一定空间位置内，接收经过该预编码向量进行预编码处理后的信号具有较好的接收功率，如满足接收解调信噪比等，而在其他空间位置内，接收经过该预编码向量进行预编码处理后的信号的功率较低，不满足接收解调信噪比。不同的通信设备可以有不同的预编码向量，即对应不同的波束，针对通信设备的配置或者能力，一个通信设备在同一时刻可以使用多个不同的预编码向量中的一个或者多个，即同时可以形成一个波束或者多个波束。波束可以理解为空间资源。可以通过一个波束标识去标识波束，波束标识可以对应配置该用户的对应的资源ID，如对应为某一个配置的信道状态信息参考信号(Channel-State Information-Reference Signal,CSI-RS)的ID或者资源，也可以是某一配置的上行探测参考信号(Sounding Reference Signal,SRS)的ID或者资源，也可以是通过该波束承载的特定信号或信道显示或隐式承载的索引信息，包括但是 不限于通过该波束发送同步信号或者广播信道指示该波束的波束标识。
S220，终端向网络设备发送测量结果。
该通信方法中，终端参考小区的波束扫描方式进行信号测量，即终端可以参考波束的扫描时间进行信号测量。更具体地说，终端可以获知各个波束的扫描时间。这有助于终端避免在检测不到信号进行信号测量，进而有助于节省终端的能耗。
其中，终端根据服务小区的波束扫描方式进行测量，可以包括：终端根据小区内的波束扫描时段进行测量。
通常情况下，每个小区中，不同波束的参考信号，如同步信号(Synchronization Signal，SS)、信道状态信息测量导频(channel state information-reference signal，CSI-RS)信号，其扫描时长可以相同或不同，但扫描时段可以不同。
例如，波束扫描方式包括小区中各个顺序扫描的波束的参考信号与时间的对应关系，且各个波束的参考信号的扫描时长均为5ms时，若终端在第1ms时检测到第一波束的参考信号，则终端可以确定第一波束的参考信号的扫描时段为第1ms至第5ms，第二波束的参考信号的扫描时段为第6ms至第10ms。依次类推，就能确定所有波束的参考信号扫描时段。本申请实施例中，可以将波束的参考信号的扫描时段简称为波束的波束扫描时段。
终端确定各个波束的波束扫描时段后，可选地，可以在各个波束的波束扫描时段进行信号测量，从而可以避免终端在检测不到信号时进行测量所导致的功率消耗。
可选地，终端可以接收网络设备发送的记录时长。记录时长可以指终端每次进行信号测量的时长。其中，该记录时长可以是终端在当前服务小区中接收的，也可以是终端在邻小区中接收的。
应注意，该记录时长是网络设备配置的，即网络设备指示终端在该记录时长内进行信号测量和记录。
现有技术中，终端接收记录时长后，可能在该记录时长内一直进行信号测量。但本申请实施例中，终端接收记录时长后，可以根据记录时长和波束扫描方式，即波束的波束扫描时段来进行信号测量。
具体地，终端根据某一个波束(为了后续描述方便，将该波束称为第一波束)的波束扫描时段和记录市场进行信号测量时，可以包括：终端可以根据小区的波束扫描方式，确定小区内的第一波束的波束扫描时段；再根据配置的记录时长和第一波束的波束扫描时段，将该记录时长内与该波束扫描时段重叠的全部或部分时段确定为目标测量时段；然后终端在目标测量时段内进行信号测量，得到测量结果。
小区中存在多个波束时，终端可以根据波束扫描方式确定各个波束的波束扫描时段，并可以将各个波束扫描时段与记录时长重叠的全部或部分时段确定为总的目标测量时段，然后在目标测量时段进行信号测量，得到测量结果。
下面以第一波束为例，详细介绍终端如何根据记录时长和波束扫描方式进行信号测量的。
终端可以根据波束扫描方式，确定小区内的第一波束的波束扫描时段。如终端可以根据第一波束的波束扫描时长为5ms，且终端在第1ms检测到第一波束的参考信号，确定第一波束的波束扫描时段为第1ms至第5ms。
若记录时长为10ms，且记录时长的起始时刻为第2ms，则终端可以将记录时长与第 一波束的波束扫描时段重叠的第2ms至第5ms这4个ms中全部时长或部分时长确定为目标测量时段。
此时，终端可以在记录时长中的能够检测到信号的4个ms内进行信号测量，而在记录时长内其他6个ms内停止信号测量，从而可以节省终端电量。
如图3所示，记录时长内，粗实线表示终端可以在第一波束方向进行信号测量的目标测量时段。
这种方法中，终端可以只在记录时长内与波束扫描时段重叠的时段进行信号测量，从而可以节省终端的能耗。
通常情况下，记录时长的长度可以大于或等于波束扫描周期的长度，这样有助于使得记录时长与第一波束的波束扫描时段有重叠时段，从而有助于保证终端能够在检测到信号的时段对信号进行测量。
如，终端的服务小区中包括8个顺序扫描的波束，每个波束的波束扫描时长为5ms，则波束扫描周期为40ms，则记录时长的长度可以大于或等于40ms。这可以使得记录时长与任意波束的波束扫描时段均有重叠部分，从而可以使得终端不论位于哪个波束的扫描区域内，均可以测量其能检测到的信号。
或者，终端确定信号的波束扫描时段后，可以根据波束扫描时段调整记录时长的起始时刻，使得波束扫描时段与记录时长具有重叠部分，以使得终端能够在检测到信号的时段对信号进行测量。
更具体地，终端可以将记录时长的起始时刻调整到第一波束的波束扫描时段的起始时刻，从而可以保证记录时长与第一波束的波束扫描时段具有重叠部分。
如图4所示，记录时长的起始时刻与第一波束的波束扫描时段的起始时刻相同，使得记录时长与第一波束的波束扫描时段具有重叠部分。
通常情况下，终端与网络设备的通信过程中，终端可以进行非连续接收(discontinuous Reception，DRX)。例如，终端可以在某些时间不接收数据时，仅在某些时间醒来后维持醒着的状态以接收数据，以节省终端的能耗。其中，UE醒来后维持醒着的时段可以称为不连续传输的接收时段，即DRX ON的时段。
可以理解地，如果终端配置了DRX，则终端根据第一波束的波束扫描时段和记录时长，将记录时长内与第一波束的波束扫描时段重叠的全部或部分时段确定为目标测量时段，可以包括：终端根据第一波束的波束扫描时段、记录时长和DRX周期内的接收DRX ON时段，将DRX ON时段内与第一波束的波束扫描时段重叠的全部或部分时段确定为目标测量时段。这样，可以使得终端仅在进行数据传输时进行信号测量，从而可以进一步节省终端的能耗。
可选地，记录时长可以是DRX周期的整数倍，相应地地，DRX ON的时段可以是波束扫描周期的整数倍。
如图5中，可以认为记录时长与DRX周期相同，即记录时长是一个DRX周期。此时，终端根据第一波束的波束扫描时段和记录时长确定目标测量时段，可以包括：终端根据DRX周期(即根据记录时长)、DRX ON时段和第一波束的波束扫描时段确定目标测量时段。
具体地，终端可以将DRX ON时段内与第一波束的波束扫描时段重叠的全部或部分 时段确定为第一波束的目标测量时段。
可选地，记录时长是DRX周期的整数倍时，用于指示记录时长的信息具体可以指示记录时长与DRX周期的倍数关系。如记录时长是DRX的1倍时，用于指示记录时长的信息可以指示1。
这样，终端接收到用于指示记录时长的信息后，可以根据DRX周期确定记录时长。
其中，第一波束的参考信号可以是服务小区的公共参考信号，比如同步信号SS，也可以是其它的信号，比如CSI-RS，CRS，或终端级别的参考信号。
可选地，终端可以从网络设备接收波束数目信息，该波束数目信息指示终端可以测量的波束数量。终端接收该波束数目信息后，正常情况下，可以在相应数目的波束方向进行信号测量。测量的波束数量达到波束数目信息指示的数量后，可以停止信号测量。
可选地，终端可以从网络设备接收测量配置信息，测量配置信息可以包括以下至少一项：记录区域信息，如一个或多个待测量小区的标识或索引；一个或多个网络通知区域(RAN notification area，RNA)信息，其中，RAN为无线接入网(radio access network)的简称；一个或多个跟踪区域(tracking area，TA)信息；一个或多个公共陆地移动网络(public land mobile network，PLMN)信息。
应注意，前述用于指示记录时长的信息可以携带在测量配置信息中。
本申请实施例中，可选地，终端可在当前小区中获取当前小区的波束扫描方式，也可以在邻小区中获取当前小区的波束扫描方式。
例如，当终端从第一个小区移到第二个小区后，若第二个小区属于待测量小区的范围，则终端可以从第二个小区的系统消息中获取第二个小区的波束扫描方式，或者，终端可以向第二个小区的网络设备发送请求消息，请求第二个小区的波束扫描方式，并接收第二个小区的网络设备根据该请求消息发送的波束扫描方式。
本申请实施例中，可选地，终端发送的测量结果中可以包括波束标识信息，或者波束标识信息和对应的波束信号质量信息。
可选地，终端还可以向网络设备发送波束标识对应的小区的小区标识。
可选地，终端还可以向网络设备发送测量时间以及测量位置等信息。
可选地，终端可以通过多种方式发送测量报告。例如，连接态的终端进行信号测量，得到测量结果后，可以即时通过无线资源控制(radio reference control，RRC)信令向网络设备发送包括测量结果的测量报告。连接态又可以称为激活态(active)。
或者，连接态的终端可以先向网络设备发送指示存在测量报告的指示信息，如MDT report indicator信息，然后终端再发送测量报告。
再如，空闲idle态或去激活RRC_INACTIVE态的终端进行信号测量得到测量结果后，可以通过基于竞争的数据传输资源，或者通过免授权(grant-free)资源向网络设备发送测量报告。
或者，空闲态或去激活态的终端可以先缓存测量报告，等到终端发送RRC消息时，如终端发起连接建立完成消息，或终端发送重建完成消息，或者终端发送重配置完成消息，或者终端发送连接恢复完成消息，或者终端发送连接重激活完成消息时，可以在上述RRC消息中携带指示存在测量报告的指示信息，如MDT report indicator信息。然后终端可以接收网络设备根据该指示信息发送的测量报告请求消息，并根据测量报告请求消息发送测量 报告。
此外，终端还可以接收网络设备发送的记录周期。其中，记录周期可以指配置的终端进行信号测量的总时长。当终端的测量总时长达到或超过记录周期时，可以停止测量。
记录时长是记录周期中的一部分。例如，记录周期可以为50ms，记录时长可以为10ms。也就是说，终端可以总共进行50ms时长的信号测量，这50ms可以分为5次测量，每次测量10ms。

可选地，网络设备还可以接收波束标识对应的小区的小区标识。
可选地，终端还可以向网络设备发送测量时间以及测量位置等信息
S620，网络设备对测量结果进行处理。
该通信方法中，网络设备可以接收包括终端根据波束扫描方式进行信号测量得到的测量结果，并根据该测量报告进行处理，有助于节省终端的能耗。
其中，网络设备对测量报告进行处理，可以包括：网络设备根据测量结果检测网络故障，修复网络问题，优化网络性能，等等。或者，网络设备可以将测量结果发送给网络管理设备，由网络管理设备根据测量结果检测网络故障、修复网络问题，优化网络性能，等等。
本申请实施例中的网络设备可以是图2所示的通信方法中的网络设备，可以实现图2所示的通信方法中的网络设备能够实现的功能，图2所示的通信方法中相关的技术特征同样适用于本申请实施例的通信方法，为了简洁，此处不再赘述。

具体地，网络设备或者网络管理设备可以从会话开始，依次选取后续接入的终端作为测量终端，直到选取的测量终端数目达到指定规格。后续接入的终端包括正常RRC连接建立接入、切换入、重建接入的终端。
确定测量终端后，网络设备可以通过RRC connection reconfiguration消息向这些测量终端发送测量配置信息，测量配置信息也可以称为配置参数。
