Description

上行传输方法及设备
本申请要求于2019年1月21日提交中国专利局、申请号为2019100546668、申请名称为“上行传输方法及设备”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
本申请实施例涉及通信技术领域，尤其涉及一种上行传输方法及设备。
背景技术
在新无线(New Radio，NR)技术中，在一些场景下，当待测的目标频点不在终端的工作带宽，终端对目标频点进行测量时，一种简单的方式是在终端中安装2种射频接收机，分别测量终端的当前频点和目标频点，但这样会带来成本提升和不同频点之间相互间干扰的问题。因此，3GPP提出了测量间隔(Measurement Gap，MG)这种方式，即在正常收发数据过程中，预留一部分时间(即测量间隔)，在这段时间内，终端不会发送和接收任何数据，而将接收机调向目标频点，对目标频点进行测量，测量间隔结束后再转到当前频点，继续进行数据收发。
目前，现有测量间隔结束之后到上行发送之间的时间间隔为固定值，对于NR技术而言并不适用，因此针对NR技术，亟需对测量间隔结束之后的上行发送行为进行规范。
发明内容
本申请实施例提供一种上行传输方法及设备，以对测量间隔结束后的上行发送行为进行规范，使得上行发送不会影响测量间隔内的测量，且不浪费资源。
第一方面，本申请实施例提供一种上行传输方法，包括：
终端在测量间隔内进行测量；
所述终端确定是否在一段时间内进行上行发送，其中，所述一段时间为从所述测量间隔结束开始的时间段，该一段时间与该测量间隔相邻，且位于测量间隔之后，该一段时间可以为以子帧、时隙、符号等为时间单位的时间段，也可以为以毫秒、微秒等为时间单位的时间；所述一段时间的时间长度是所述终端根据通信参数确定的，该通信参数可以为用于表征小区覆盖范围、终端与网络设备的实际距离的参数。
可选的，当测量间隔提前导致产生与测量间隔部分交叠的时隙时，该一段时间与所述与测量间隔有部分交叠的时隙相邻，且位于该时隙之后，该一段时间可以为以子帧、时隙、符号等为时间单位的时间段，也可以为以毫秒、微秒等为时间单位的时间；所述一段时间的时间长度是所述终端根据通信参数确定的，该通信参数可以为用于表征小区覆盖范围、终端与网络设备的实际距离的参数。
由于该一段时间的时间长度是根据通信参数确定的，因此，该一段时间的时间长 度不是确定值，可以根据通信参数灵活确定，在终端根据实现不在该一段时间进行上行发送时，避免终端定时提前的存在，导致终端的上行发送落在该测量间隔内的情况，也避免了在测量间隔结束后，终端长时间不进行上行发送导致的资源浪费。
在第一方面的一种可能的设计中，所述通信参数为所述终端的定时提前量；所述定时提前量与所述时间长度具有映射关系，其中，若第一定时提前量小于第二定时提前量，则所述第一定时提前量对应的第一时间长度不大于所述第二定时提前量对应的第二时间长度。例如，定时提前量和时间长度可以为正相关的关系，即定时提前量越大，则时间长度越大，从而避免终端在测量间隔内进行上行发送。
在第一方面的一种可能的设计中，所述时间长度为所述定时提前量的阶跃函数，若TA∈[0，a-x)，则TL＝a；若TA∈[a-x，b-x]，则TL＝b；
其中，所述TA为定时提前量，所述TL为所述时间长度，所述a＝Ns，所述b＝a+Ms，所述N、M为正整数，所述s为半个或一个时隙长度或一个符号长度，所述X为余量，所述X的长度为循环前缀CP的长度。
通过根据定时提前量确定该一段时间的时间长度，该时间长度大于定时提前量，从而当该终端决定不在该一段时间内进行上行发送，在该一段时间结束后进行上行发送时，终端的定时提前操作不会影响终端在测量间隔内的测量，也保证终端能够及时进行上行发送，提高资源利用率。
在第一方面的一种可能的设计中，所述通信参数为所述终端的服务小区的参数信息；所述服务小区的参数信息包括如下中的一个或者他们的组合：子载波间隔、频率范围。

所述频率范围与所述时间长度具有映射关系，其中，若第一频率范围对应的频段高于第二频率范围对应的频段，则所述第一频率范围对应的第一时间长度不大于所述第二频率范围对应的第二时间长度。子载波间隔与该时间长度可以为负相关的关系，即子载波间隔越大，则时间长度越小，子载波间隔与时间长度的映射关系也可以为阶跃函数。
通过子载波间隔或频率范围来确定该一段时间的长度，主要考虑一定的子载波间隔或者频率范围下可能支持的最大的小区半径，从而当该终端决定不在该一段时间内进行上行发送，在该一段时间结束后进行上行发送时，终端的定时提前不会影响终端在测量间隔内的测量，也保证终端能够及时进行上行发送，提高资源利用率。
在第一方面的一种可能的设计中，所述通信参数为第一消息；所述方法还包括：

所述终端接收所述网络设备发送的第二消息，所述第二消息中携带所述保护间隔，所述时间长度是所述终端根据所述保护间隔确定的。该第二消息可以为系统消息或配置消息。
通过第二消息中携带的保护间隔，来隐式指示该一段时间的时间长度，不会增加网络设备与终端设备之间的信令开销。该时间长度是根据通信参数确定的，即该一段时间的时间长度不是固定值，终端根据网络设备的调度，在该一段时间结束后进行上行发送时，不会影响在该测量间隔内的测量，也保证终端能够及时进行上行发送，提高资源利用率。
在第一方面的一种可能的设计中，若所述终端被配置了多个服务小区；
每个所述服务小区分别各自对应一个一段时间，所述一段时间的时间长度是根据对应的服务小区的通信参数确定的；或者

具体实施方式
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。
本申请实施例可以应用于无线通信系统，需要说明的是，本申请实施例提及的无线通信系统包括但不限于：窄带物联网系统(Narrow Band-Internet of Things，NB-IoT)、全球移动通信系统(Global System for Mobile Communications，GSM)、增强型数据速率GSM演进系统(Enhanced Data rate for GSM Evolution，EDGE)、宽带码分多址系统(Wideband Code Division Multiple Access，WCDMA)、码分多址2000系统(Code Division Multiple  Access，CDMA2000)、时分同步码分多址系统(Time Division-Synchronization Code Division Multiple Access，TD-SCDMA)，长期演进系统(Long Term Evolution，LTE)以及第五代移动通信(the 5 th Generation，简称5G)的新无线(New Radio，NR)移动通信系统。
下面结合图1对本申请实施例的可能的网络架构进行介绍。图1示出了本申请实施例可能适用的一种网络架构。如图1所示，本实施例提供的网络架构包括网络设备101和终端102。
其中，网络设备101是一种将终端接入到无线网络的设备，可以是全球移动通讯(Global System of Mobile communication，简称GSM)或码分多址(Code Division Multiple Access，简称CDMA)中的基站(Base Transceiver Station，简称BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，简称WCDMA)中的基站(NodeB，简称NB)，还可以是长期演进(Long Term Evolution，简称LTE)中的演进型基站(Evolved Node B，简称eNB或eNodeB)，或者中继站或接入点，或者未来5G网络中NR制式的网络侧设备(例如基站)或未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的网络设备等，在此并不限定。图1示意性的绘出了一种可能的示意，以该网络设备101为基站为例进行了绘示。
该终端102也可以称为终端设备，该终端可以是无线终端也可以是有线终端，无线终端可以是指向用户提供语音和/或其他业务数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经无线接入网(Radio Access Network，简称RAN)与一个或多个核心网进行通信，无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，个人通信业务(Personal Communication Service，简称PCS)电话、无绳电话、会话发起协议(Session Initiation Protocol，简称SIP)话机、无线本地环路(Wireless Local Loop，简称WLL)站、个人数字助理(Personal Digital Assistant，简称PDA)等设备。无线终端也可以称为系统、订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)，在此不作限定。
图1示意性的绘出了一种可能的示意。其中，网络设备101和终端102A-102F组成一个通信系统。在该通信系统中，在终端102A-102F可以发送上行数据或信号给网络设备101，网络设备101需要接收终端102A-102F发送的上行数据或信号；网络设备101可以发送下行数据或信号给终端102A-102F，终端102A-102F需要接收网络设备101发送的下行数据或信号。此外，终端102D-102F也可以组成一个通信系统。在该通信系统中，网络设备101可以发送下行数据给终端102A、终端102B、终端102E等；终端102E也可以发送下行数据或信号给终端102D、终端102F。
在图1所示的通信系统中，网络设备与终端之间存在传播距离，该传播距离会产生网络设备与终端之间的传输时延。图2为本申请实施例提供的网络设备和终端的定时示意图。如图2所示，由于该传输时延，在下行(Downlink，DL)传输过程中，终端的下行定时是晚于网络设备的。在上行(Uplink，UL)传输时，为了保证与网络设备的距离不同的终端发送的信号可以同时到达网络设备，终端会对上行发送使用定时提前量(Timing Advance， TA)，因此终端的上行定时是早于网络设备的。例如，在NR中，终端可以通过检测同步信号块(Synchronization Signal Block，SSB)来获取小区的物理小区标识、定时信息以及基于SSB的测量结果等。
当待测的目标频点不在终端的工作带宽，终端在测量间隔内对目标频点进行测量。该测量可以为同频测量，也可以为异频测量，本实施例对终端进行测量的具体实现方式不做特别限制。终端在该测量间隔内即不发送数据，也不接收数据。在NR中，在确定测量间隔的起始点时，不管测量间隔之前终端实际进行的是上行发送还是下行接收，终端都参考下行定时。在终端被配置了多个服务小区的情况下，不同的服务小区由于距离网络设备的远近不同，可能有不同的定时，测量间隔的起点参考所有服务小区里最晚的一个小区的下行定时。本实施例对该测量间隔的测量间隔长度(Measurement Gap Length，MGL)不做特别限制。
在测量间隔结束之后，终端可以立即接收网络设备发送的下行数据或信号，但是考虑终端的上行定时提前，以避免上行发送位于测量间隔内，对测量产生干扰，以及考虑NR的小区半径范围很大，从几十米到几百公里，目前在测量间隔后通过设定固定的1ms或1个时隙的时间不进行上行发送，该1ms或1个时隙可能不够或浪费的问题，因此对上行发送的行为需要规范。本申请实施例将针对终端的上行发送，规范终端在测量间隔结束后多久可以进行上行发送，同时明确了网络设备在测量间隔结束后可调度的上行资源。
图3为本申请一实施例提供的上行传输的信令流程图，如图3所示，该方法包括：
S301、终端在测量间隔内进行测量。
S302、所述终端确定是否在一段时间内进行上行发送，其中，所述一段时间为从所述测量间隔结束开始的时间段，所述一段时间的时间长度是所述终端根据通信参数确定的。
在本实施例中，终端在测量间隔内进行测量，该测量可以为同频测量也可以为异频测量，本实施例对终端在测量间隔内所进行的测量不做特别限制。在该测量间隔内，终端不会发送和接收任何数据，而将接收机调向目标频点，对该目标频点进行测量。
在该测量间隔结束后，终端确定是否在一段时间内进行上行发送。其中，在一种可能的实现方式中，该一段时间为从测量间隔结束开始的时间段，该一段时间的时间长度是根据通信参数确定的。
其中，本实施例所涉及的测量间隔、一段时间、时间长度等与时间相关的概念，均是针对通信系统的系统时间来定义的。其中，系统时间是指终端和网络设备同时遵循的时间。该系统时间与网络设备的时间相同。
该一段时间可以为以子帧、时隙、符号等为时间单位的时间段。该符号可以为正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号，该一段时间也可以为以毫秒、微秒等为时间单位的时间，本实施例对该一段时间的单位不做特别限制。
在另一种可能的实现方式中，当测量间隔提前而产生与测量间隔的尾部存在部分交叠的时隙时，该一段时间与所述与测量间隔有部分交叠的时隙相邻，且位于该时隙之后，该一段时间可以为以子帧、时隙、符号等为时间单位的时间段，也可以为以毫秒、微秒等为时间单位的时间；所述一段时间的时间长度是所述终端根据通信参数确定的，该通信参数可以为用于表征小区覆盖范围、终端与网络设备的实际距离的参数。
终端可以根据实现决定是否在一段时间内进行上行发送。在一种可能的方式中，若终端具有两个射频收发机，则终端通过一个射频收发机在测量间隔内进行测量，通过另一个收发机在该一段时间内进行上行发送。在另一种方式中，网络设备在该一段时间内调度终端进行上行发送，而终端为了避免上行发送对在测量间隔内所进行的测量造成影响，则终端确定不再该一段时间内进行上行发送。在又一种方式中，终端在测量间隔还未结束时，终端完成了测量，则终端确定在该一段时间内进行上行发送。
即在一些场景下，终端可以在该一段时间内进行上行发送，在一些场景下，终端在该一段时间内进行上行发送将影响测量，即终端不可以进行上行发送。本实施例对终端根据实现决定是否在一段时间内进行上行发送的可能的方式，本实施例此处不再赘述。
本领域技术人员可以理解，当终端决定在该一段时间结束后进行上行发送，即网络设备能够在该一端时间结束后开始进行上行接收。终端在进行上行发送时，需要考虑终端与网络设备的上行同步，终端根据该一段时间结束的终点和定时提前量进行上行发送。
其中，该上行发送可以为物理上行链路控制信道(Physical Uplink Control Channel，PUCCH)以及物理上行链路共享信道(Physical Uplink Shared Channel，简称PUSCH)以及探测参考信号(Sounding Reference Signal，SRS)等的上行发送，本实施例对具体的上行发送不做特别限制。
图4为本申请一实施例提供的一段时间的示意图。如图4所示，本实施例以系统时间与网络设备定时一致为例进行说明。在测量间隔(Measurement Gap，MG)结束后，紧接着为该一段时间。本领域技术人员可以理解，对于终端在测量间隔结束后的上行发送，网络设备在该测量间隔结束后保持上行接收状态，该一段时间为上行接收时间的一部分，即在该一段时间内，若该终端可以进行上行发送，则网络设备可以进行上行接收，若该终端不能进行上行发送，则网络设备在该一段时间结束后开始上行接收。
在本实施例中，该一段时间的时间长度是根据通信参数确定的。即该一段时间的时间长度不是固定值，而是根据终端所处的通信环境对应的通信参数确定的。可以考虑不同频率范围的小区覆盖范围、或考虑网络实际部署的小区覆盖范围，或考虑终端与网络设备的实际距离，从而确定该一段时间的时间长度。例如，小区覆盖范围越大，则该时间长度越大，或者该实际距离越大，则该时间长度越大。该通信参数可以为用于表征小区覆盖范围的参数，也可以为表征终端与网络设备的距离的参数。
在一种可能的设计中，该通信参数可以为终端的服务小区的参数，例如子载波间隔、频率范围等，该通信参数还可以终端的通信参数，例如终端的定时提前等。该通信参数还可以为系统的保护间隔等，本实施例对该通信参数不做特别限制。
终端可以根据通信参数确定该一段时间的长度，也可以由网络设备确定该一段时间的时间长度，然后由网络设备向终端指示该一段时间的长度。
由于该一段时间的时间长度是根据通信参数确定的，因此，该一段时间的时间长度不是确定值，可以根据通信参数灵活确定，在终端根据实现不在该一段时间进行上行发送时，避免终端定时提前的存在，导致终端的上行发送落在该测量间隔内的情况，也避免了在测量间隔结束后，终端长时间不进行上行发送导致的资源浪费。
本申请实施例提供的上行传输方法，终端在测量间隔内进行测量，在测量间隔结束后，终端确定是否在一段时间内进行上行发送，其中，一段时间为从测量间隔结束 开始的时间段，该一段时间的时间长度是根据通信参数确定的，即该一段时间的时间长度不是固定值，从而对终端在测量间隔后的上行发送进行了规范，同时终端决定在该一段时间内进行上行发送时，不会影响在该测量间隔内的测量，当该终端决定不在该一段时间内进行上行发送，则终端在该一段时间结束后进行上行发送，一方面终端的定时提前不会影响终端在测量间隔内的测量，另一方面也保证终端能够及时进行上行发送，提高资源利用率。
在上述实施例的基础上，该一段时间可以由终端根据通信参数决定，也可以有网络设备根据通信参数决定，然后由网络设备发送给终端。其中，网络设备和/或终端根据通信参数确定该一段时间可以至少包括如下可能的实现方式。
一种可能的实现方式，所述通信参数为所述终端的定时提前量。
该定时提前量可以为初始定时提前过程的定时提前量或定时提前更新过程的定时提前量。在随机接入过程中，网络设备根据终端发送的随机接入前导确定初始定时提前，并向终端发送携带该初始定时提前的随机接入响应。然而，随着终端与网络设备之间的距离的改变，该初始定时提前将不再适用，需要对该定时提前进行更新。当终端定时提前需要调整时，网络设备向终端发送定时提前命令，该定时提前命令包括调整信息，终端根据该调整信息来更新定时提前。在一种可能的实现方式中，根据38.133的要求，上行发送相对于参考小区的下行第一个可检测径提前为(N TA+N TA_offset)×T c，本发明中所述定时提前量可以为(N TA+N TA_offset)×T c，其中，所述N TA为网络侧向终端配置的定时提前量，所述N TA_offset为固定偏移提前量，所述T c为时间单位。
示例性地，该时间长度可以大于或等于该定时提前量。示例性地，所述定时提前量与所述时间长度具有映射关系。其中，若第一定时提前量小于第二定时提前量，则第一定时提前量对应的第一时间长度不大于第二定时提前量对应的第二时间长度。
示例性地，定时提前量和时间长度可以为正相关的关系，即定时提前量越大，则时间长度越大。本实施例对终端确定定时提前量的实现方式不做特别限制。
在一种可能的设计中，时间长度为定时提前量的阶跃函数，若TA∈[0，a-x)，则TL＝a；若TA∈[a-x，b-x]，则TL＝b；其中，TA为定时提前量，TL为时间长度，a＝Ns，b＝a+Ms，N、M为正整数，s为半个或一个时隙长度或一个符号长度，X为余量。该余量可以根据经验值来设定，也可以根据其它因素确定。该符号例如可以为OFDM符号。例如X的长度为循环前缀CP的长度。可选的，当测量间隔提前(MGTA)导致产生与测量间隔部分交叠的时隙时，s为半个时隙长度，其它情况下为以一个时隙长度。
该循环前缀(Cyclic Prefix，CP)可以为常规循环前缀、扩展循环前缀或其它类型的循环前缀，本实施例对循环前缀的类型不做特别限制。
X作为余量主要考虑终端自主的定时调整，该余量可以为CP的长度，也可以为其它长度，本实施例对该余量的实现方式不做特别限制。
在本实施例中，属于同一范围的定时提前量对应相同的时间长度，例如，介于a-x与b-x之间的TA，对应相同的时间长度。对于位于边界的定时提前量，例如a-x、b-x等，可以确定a-x、b-x为右边界时对应的时间长度为最终的时间长度。例如，a-x对应的时间长度为a，而不是b，b-x对应的时间长度为b。或者，也可以确定a-x、b-x为左边界时对应的时间长度为最终的时间长度。例如，a-x对应的时间长度为b，而不是a。本实施 例对边界取值不做特别限制，只要保证边界对应的时间长度的取值唯一即可。
示例性地，本实施例给出了该阶跃函数的部分，该阶跃函数还可以包括更多的内容，例如，若TA∈[b-x，c-x]，则TL＝c，若TA∈[c-x，d-x]，则TL＝d……依次类推。其中，该a、b、c、d可以为逐渐递增的数列，例如，a、b、c、d为等差数列，公差为半个或一个时隙的整数倍。
由上可知，本实施例中的时间长度为半个时隙长度的整数倍，且该时间长度大于定时提前量。该时间长度与定时提前量的差值不小于循环前缀的长度。
示例性地，对于终端距离网络设备较近时，例如终端与网络设备的距离为500米，实际的定时提前量在3.3us，使用上述固定的1ms的时间长度，会造成不必要的资源浪费，通过对定时提前量进行划分，可以得到多个时间长度，可以根据定时提前量所属的范围，确定该定时提前量对应的时间长度，从而避免资源浪费。
本实施例通过根据定时提前量确定该一段时间的时间长度，该时间长度大于定时提前量，从而当该终端决定不在该一段时间内进行上行发送，在该一段时间结束后进行上行发送时，终端的定时提前操作不会影响终端在测量间隔内的测量，也保证终端能够及时进行上行发送，提高资源利用率。
又一种可能的实现方式：通信参数为该终端的服务小区的参数信息。例如，该服务小区的参数信息包括如下中的一种或他们的组合：子载波间隔、频率范围。
子载波间隔与该时间长度具有映射关系。5G业务使用的频段的跨度很大，部署方式也多种多样。5G NR的子载波间隔为15×2 nKHz，其中n为整数，例如，子载波间隔为15KHz在、30KHz、60KHz、120KHz、240KHz。其中，设计大的子载波间隔的目的是支持时延敏感型业务、小面积覆盖场景，和高载频场景，而设计小的子载波间隔的目的是支持低载频场景、大面积覆盖场景、窄带宽设备和增强型广播/多播业务。
其中，若第一子载波间隔大于第二子载波间隔，则第一子载波间隔对应的第一时间长度不大于第二子载波间隔对应的第二时间长度。
在本实施例中，子载波间隔与该时间长度可以为负相关的关系，即子载波间隔越大，则时间长度越小，子载波间隔与时间长度的映射关系也可以为阶跃函数。例如，子载波间隔15KHz和30KHz映射时间长度A，子载波间隔60KHz和120KHz映射时间长度B，子载波间隔240KHz映射时间长度C，对应地时间长度A＞时间长度B＞时间长度C。
不同的小区，小区的频率范围可能不同。其中，小区的频率范围是指频段高低的频率范围。频率范围与时间长度具有映射关系，其中，若第一频率范围对应的频段高于第二频率范围对应的频段，则第一频率范围对应的第一时间长度不大于第二频率范围对应的第二时间长度。
其中，频段高的小区覆盖面积小，频段低的小区覆盖面积大，因此，频率范围(Frequency Range，FR)对应的频段的高低与该时间长度可以为负相关的关系，即频段越高，则时间长度越小，或者与子载波间隔类似，也可以为阶跃函数的关系，即存在相邻的两个频段对应的时间长度相同的情况。根据不同的频率范围，确定适用于终端的一段时间，例如FR1中终端的最早上行发送时间距离测量间隔结束2ms，FR2中终端的最早上行发送时间距离测量间隔结束0.125ms。
本实施例通过子载波间隔或频率范围来确定该一段时间的长度，主要考虑一定的子载波间隔或者频率范围下可能支持的最大的小区半径，从而当该终端决定不在该一段时间内进行上行发送，在该一段时间结束后进行上行发送时，终端的定时提前不会影响终端在测量间隔内的测量，也保证终端能够及时进行上行发送，提高资源利用率。
在又一种可能的实现方式中，通信参数为网络设备向终端发送的第一消息，该第一消息用于指示该时间长度。
其中，该第一消息可以为配置信息或指示信息或终端与网络设备的其它通信信息，本实施例对该第一消息的实现方式不做特别限制。该第一消息中设置有指示域，该指示域用于显示指示该时间长度。
通过网络设备向终端显示指示该时间长度，终端能够高效直接的获取该时间长度，提高了终端的处理效率。
在又一种可能的实现方式中，该时间长度是根据保护间隔确定的。其中，该保护间隔是下行传输到上行传输的保护间隔(Guard Period，GP)，以降低上下行传输间的干扰。该保护间隔可以灵活配置，在不同的场景下，保护间隔的长度不同，本实施例对网络设备确定保护间隔的实现方式不做特别限制。
该保护间隔会由网络设备配置给终端，终端可以根据该保护间隔来确定一段时间的时间长度，例如，该时间长度即为保护间隔的时间长度。
本领域技术人员可以理解，对于网络设备而言，网络设备可以通过隐式指示的方式向终端指示该时间长度，例如终端通过保护间隔确定时间长度。对于终端而言，该保护间隔可以理解为通信参数，终端根据该保护间隔确定了该一段时间的时间长度。
本实施例通过网络设备向终端设备发送保护间隔，来隐式指示该一段时间的时间长度，节省了网络设备与终端之间的信令开销，终端将该保护间隔的长度作为该一段时间的时间长度，终端不需要进行其它处理，从而减小了终端的处理，节省了终端的资源。
在上述实施例中，给出了终端和/或网络设备根据通信参数确定一段时间的时间长度的几种可能的实现方式，本申请实施例并不限于上述可能的实现方式，还包括其它可能的实现方式，例如，对上述几种可能的实现方式进行变形得到的其它实现方式，或者对上述几种可能的实现方式中的一种或多种进行结合衍生出其它实现方式，等等。本实施例对根据通信参数得到时间长度的实现方式不做特别限制，只要网络设备与终端在确定时间长度时具有相同的理解即可。
在上述实施例的基础上，针对网络设备在确定了该一段时间的时间长度，根据该一段时间的长度对终端进行调度和配置，下面结合图5至图6进行详细说明。对于相同或相似的步骤或技术术语，可参见上述实施例，在下述实施例中将不再赘述。
图5为本申请一实施例提供的上行传输的信令流程图。如图5所示，该流程包括：
S501、网络设备生成调度信息，所述调度信息用于调度终端在一段时间结束后进行上行传输；其中，所述一段时间为从测量间隔结束开始的时间段，所述一段时间的时间长度是根据通信参数确定的，所述测量间隔为所述终端进行测量的时间；
S502、网络设备向终端发送调度信息；
S503、终端在测量间隔内进行测量；
S504、终端确定是否在一段时间内进行上行发送。
在本实施中，网络设备向终端发送调度信息，该调度信息避免调度终端在一段时间内进行上行传输，例如，在终端有上行传输时，该调度信息可以包括终端用于上行发送的上行资源的信息。其中，该调度信息是根据该一段时间的时间长度确定的，该调度信息避免调度一段时间内的上行资源，即该上行资源不包括该一段时间内的资源。网络设备可以调度终端在一段时间结束后的资源上进行上行发送，该资源为一段时间后的用于上行发送的资源。该一段时间的时间长度是根据通信参数确定的，具体可参见上述实施例，本实施例此处不再赘述。本领域技术人员可以理解，终端没有上行数据传输时，则网络设备可以不调度终端的上行传输。
终端在收到该调度信息后，在测量间隔内进行测量，具体的实现过程可参见上述图3所示实施例，本实施例此处不再赘述。
本实施例提供的上行传输方法，网络设备通过向终端设备发送调度信息，避免调度终端在一段时间内的上行传输，该一段时间的时间长度是根据通信参数确定的，即该一段时间的时间长度不是固定值，从而明确了网络设备可调度的资源，终端根据网络设备的调度，在该一段时间结束后进行上行发送时，不会影响在该测量间隔内的测量，也保证终端能够及时进行上行发送，提高资源利用率。
图6为本申请一实施例提供的上行传输的信令流程图。如图6所示，该流程包括：
S601、网络设备向终端发送第一消息，所述第一消息用于指示一段时间的时间长度，其中，所述一段时间为从测量间隔结束开始的时间段，所述一段时间的时间长度是根据通信参数确定的，所述测量间隔为所述终端进行测量的时间；
S602、终端在测量间隔内进行测量。
S603、在所述测量间隔结束后，所述终端确定是否在一段时间内进行上行发送。
在本实施例中，网络设备可以通过第一消息向终端显式指示该一段时间的时间长度。例如，该第一消息可以为高层信令，该高层信令例如为系统信息、无线资源控制消息、下行控制信息等，该高层信令中可以增加指示域，该指示域用于指示该一段时间的时间长度。再例如，该第一消息还可以为独立的配置信息，即新增的指示信令，该指示信令中存在指示域来指示该一段时间的时间长度。
其中，第一消息中的指示域可以直接指示该时间长度，或者，该第一消息中的指示域的指示值与时间长度具有对应关系，终端根据该对应关系和指示值来确定时间长度。本实施例对第一消息指示时间长度的实现方式不做特别限制。
本实施例提供的上行传输方法，网络设备通过向终端发送第一消息来指示一段时间的时间长度，能够显式指示该时间长度，使得终端能够快速获取便捷的获取该时间长度，该时间长度是根据通信参数确定的，即该一段时间的时间长度不是固定值，终端根据网络设备的调度，在该一段时间结束后进行上行发送时，不会影响在该测量间隔内的测量，也保证终端能够及时进行上行发送，提高资源利用率。
图7为本申请一实施例提供的上行传输的信令流程图。如图7所示，该流程包括：
S701、网络设备向终端发送第二消息，所述第二消息中携带保护间隔，所述保护间隔用于隐式指示一段时间的时间长度，其中，所述一段时间为从测量间隔结束开始的时间段，所述测量间隔为所述终端进行测量的时间；
S702、终端在测量间隔内进行测量；

该第二消息可以为系统消息，该系统消息中携带保护间隔；该第二消息还可以为配置消息，在配置消息中携带保护间隔，本实施例对第二消息的实现方式不做特别限制。
终端在接收到第二消息后，终端根据该第二消息中的保护间隔确定该时间长度，具体的，终端将该保护间隔的时间长度确定为该一段时间的时间长度。
本实施例提供的上行传输方法，网络设备通过第二消息中携带的保护间隔，来隐式指示该一段时间的时间长度，不会增加网络设备与终端设备之间的信令开销。该时间长度是根据通信参数确定的，即该一段时间的时间长度不是固定值，终端根据网络设备的调度，在该一段时间结束后进行上行发送时，不会影响在该测量间隔内的测量，也保证终端能够及时进行上行发送，提高资源利用率。
在上述实施例的基础上，终端可以通过图5至图7所示实施例中的其中一种实现方式来确定该一段时间的时间长度。
或者，终端在通过图5所示实现方式获取调度信息，同时终端还可以通过图6或图7所示实现方式来获取该一段时间的时间长度。
在上述实施例的基础上，若终端被配置了多个服务小区，终端在每个服务小区上都可以进行上行发送。终端和网络设备确定该一段时间的时间长度包括以下可能的实现方式。
一种可能的实现方式为：每个服务小区分别各自对应一个一段时间，所述一段时间的时间长度是根据对应的服务小区的通信参数确定的。
示例性地，根据上述的实现方式来获取每个服务小区的一段时间的时间长度，建立服务小区与一段时间的时间长度的一一对应关系，即每个服务小区各自对应一个时间长度。
另一种可能的实现方式为：所有服务小区对应一个一段时间，所述一段时间是根据各服务小区的通信参数确定的多个时间长度中的最大值确定的。
示例性地，根据上述的实现方式来获取每个服务小区的一段时间的时间长度，然后在所有时间长度中确定最长的时间长度为最终的时间长度，建立所有服务小区与该最长的时间长度的对应关系。
又一种可能的实现方式为：每个服务小区组分别各自对应一个一段时间，所述一段时间是根据组内所有服务小区的通信参数确定的多个时间长度中的最大值确定的；所述服务小区组是根据各服务小区所在的频率范围或者各服务小区所在的定时提前组确定的。
将所有的服务小区分成多个组，在分组过程中，可以根据频率范围进行划分，即位于同一频率范围的服务小区为一个组，还可以根据服务小区的定时提前组进行划分， 位于同一定时提前组的服务小区为一个组。
其中，每个服务小区组分别各自对应一个一段时间，即服务小区组与一段时间为一一对应的关系。针对每个小区组的一段时间，该一段时间是根据组内所有服务小区的通信参数确定的多个时间长度中的最大值确定的。即服务小区组内的每个服务小区各自对应一个时间长度，将最大的时间长度作为该服务小区组的时间长度。
本实施例给出了终端被配置了多个上行服务小区时，终端确定该一段时间的时间长度的实现方式，使得终端在多个服务小区的场景下，终端在测量间隔后的上行发送不会影响在该测量间隔内的测量，也可以保证终端能够及时进行上行发送，提高资源利用率。
本申请还提供一实施例，该实施例对网络设备对终端配置时隙格式指示进行说明。
在NR中，时域的基本调度单位为时隙(slot)或迷你时隙(mini-slot)，这里为了简便统称为时隙。时隙由若干个OFDM符号组成。NR支持灵活的时隙格式，即一个时隙中的符号可全部用于传输上行数据、全部用于传输下行数据、部分用于传输上行数据或者部分用于传输下行数据。时隙格式也可理解为时隙格式(Slot Format)，或时隙格式相关信息(Slot format related information)。该时隙格式可由公共物理下行控制信道中携带的控制信息进行指示。
该下行控制信息包括时隙格式指示(Slot Format indication，SFI),该时隙格式指示用于指示一个时隙中哪些符号为上行符号，哪些为下行符号，或者哪些为保护间隔。
在一种可能的实现方式中，网络设备在为终端配置时隙格式指示(SFI)时，应保证：
如果测量间隔后的时隙中没有下行传输的符号，则测量间隔的末尾与第一个上行发送的符号间应留有足够大的保护间隔以保证上行传输不受影响。
如果测量间隔后的时隙中有下行传输的符号，则最后一个下行符号与第一个上行发送的符号间应留有足够大的保护间隔以保证上行传输不受影响。
例如，假设终端实际的TA与上下行转换时间加和后的长度为两个符号，则网络设备在为终端配置SFI时应保证保护间隔后的第一个上行符号前至少有两个符号不用于接收或者发送，而是作为保护间隔以保证上行传输不受影响。
