本申请要求在2018年08月09日提交中国专利局、申请号为201810903438.9、申请名称为“一种时长配置方法、装置及设备”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
本申请涉及通信技术领域，尤其涉及一种时长配置方法、装置及设备。
背景技术
在智能网联汽车技术(Vehicle-to-Everything，简称V2X)通信中，一个接收用户设备(User Equipment，简称UE)可能需要接收多个不同发送UE的信号，由于发送UE的位置不同，那么到达接收UE的时候其信号强度的变化可能会比较大，所以需要对接收信号进行功率调整。UE的接收机包括有自动增益控制(Automatic Gain Control，简称AGC)调整模块和模数转换(Analog-to-Digital Converter，简称ADC)模块，AGC用于调整信号进入ADC的功率，保证进行ADC的功率在一定的范围内变化，从而有助于降低ADC采样的时候的量化误差。在实现中需要引入AGC测量的过程，通过一段时间的调整，从而使得AGC收敛到一个稳定的状态。现有技术固定使用一个子帧或时隙的第一个正交频分复用(Orthogonal Frequency Division Multiplexing，简称OFDM)符号完成AGC测量调整。另外考虑到UE自身的收/发转换带来的影响，由于UE可能在前一个子帧或时隙处于接收的状态，在后一个子帧或时隙可能处于发送的状态，那么为了给收/发之间的转换预留时间完成转换动作，需要在子帧或时隙之间引入保护间隔(Guard Period，简称GP)，现有技术GP也固定占用一个符号。而5G新无线接入技术(NR Radio Access，简称NR)中引入了灵活的子载波间隔配置，导致子帧中符号长度变化，不再是固 定值。而AGC和/或GP所需要的时长一般是固定值，按照现有技术中配置AGC或GP固定占用一个符号，会导致在较大的子载波间隔情况下，符号长度缩短，导致没有足够的时间去完成AGC和/或GP，使得接收机误码率上升，系统资源利用率下降。
发明内容

具体实施方式
为了使本申请的目的、技术方案及有益效果更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
本申请实施例适用的系统架构如图1所示，该系统架构中包括发送终端101、接收终端102以及基站103。
发送终端101和接收终端102为具备网络通信能力的电子设备，该电子设备可以是智能手机、平板电脑、便携式个人计算机、智能汽车、智能家居等等。基站103是一种将发送终端101和接收终端102接入到无线网络的设备，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)、基站(g nodeB，gNB)、传输点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)、移动交换中心等。发送终端101和接收终端102之间可以通过基站103进行通信，也可以直接进行Sidelink通信。
基于图1所示的系统架构图，本申请实施例提供了一种时长配置方法的流程，该方法的流程可以由时长配置装置执行，如图2所示，包括以下步骤：
步骤S201，获取子载波间隔信息。
可选地，子载波间隔信息可以是子载波间隔的设置信息，比如子载波间隔为7.5kHz、15kHz、30kHz、60kHz等等。子载波间隔信息还可以是与子载波间隔关联的信息。
步骤S202，根据子载波间隔信息确定自动增益控制占用的时长信息和/或保护间隔占用的时长信息。
时长信息包括但不限于OFDM符号数量信息、Ts信息。
具体地，本申请实施了提供至少以下两种根据子载波间隔信息确定自动增益控制占用的时长信息和/或保护间隔占用的时长信息的实施方式：
在一种可能的实施方式中，预先设置对照表，该对照表中保存了预先保存了子载波间隔信息与自动增益控制占用的时长信息和/或保护间隔占用的时长信息之间的对应关系。然后根据载波间隔信息查询该对照表确定自动增益控制占用的时长信息和/或保护间隔占用的时长信息。
示例性地，设定时长信息为OFDM符号数量信息，预设的对照表如表1所示：
表1
序号 Sidelink子载波间隔 AGC占用符号个数 GP占用符号个数
1 15KHz 1 1
2 30KHz 2 2
3 60KHz 4 4
当获取Sidelink子载波间隔为30KHz，查询表1所示对照表可知AGC占用符号个数为2个，GP占用符号个数占用的符号个数为2个，对应得到的时隙结构如图3所示，其中，AGC占用时隙中第0个符号、第1个符号，GP占用时隙中第12个符号、第13个符号，数据(DATA)和解调导频(Demodulation Reference Signal，简称DMRS)占用时隙中其他符号。由于预先设置对照表，直接查询对照表即可获取自动增益控制占用的符号数量和/或保护间隔占用的符号数量，不需要根据子载波间隔计算，方便快捷。
在另一种可能的实施方式中，如图4所示，包括以下步骤：
步骤401，根据子载波间隔信息确定时长单位信息。
可选地，时长单位信息可以以单个OFDM符号作为时长单位，也可以是以Ts作为时长单位。当以单个OFDM符号作为时长单位时，子载波间隔与OFDM符号长度成反比，具体如以下公式(1)所示：
OFDM符号长度＝1/子载波间隔………………(1)
在获取子载波间隔后，可以根据公式(1)计算出每个OFDM符号的符号长度。
步骤S402，根据自动增益控制所需时长和时长单位信息确定自动增益控制占用的时长信息。
步骤S403，根据保护间隔所需时长和时长单位信息确定保护间隔占用的时长信息。
自动增益控制所需时长和保护间隔所需的时长固定，一般与器件性能相关。当以单个OFDM符号作为时长单位时，采用公式(1)计算出OFDM符号长度后，根据自动增益控制所需时长可确定自动增益控制需要占用的OFDM符号数量，根据保护间隔所需时长可确定保护间隔需要占用的OFDM符号数量。
可选地，在步骤S402中，时长配置装置可以直接将计算得到的自动增益控制需要占用的OFDM符号数量配置为接收终端中自动增益控制实际占用的OFDM符号数量。示例性地，设定子载波间隔为30kHz，通过计算得到自动增益控制需要占用的OFDM符号数量为2个，则配置接收终端中自动增益控制占用2个OFDM符号。
时长配置装置也可以结合计算出的自动增益控制需要占用的OFDM符号数量以及实际通信场景配置接收终端中自动增益控制实际占用的OFDM符号数量。示例性地，设定子载波间隔为30kHz，通过计算得到自动增益控制需要占用的OFDM符号数量为2个，可以结合实际通信场景配置接收终端中自动增益控制占用1个OFDM符号。
同样地，在步骤S403中，时长配置装置可以直接将计算得到的保护间隔需要占用的OFDM符号数量配置为接收终端中保护间隔实际占用的OFDM符号数量。也可以结合计算出的保护间隔需要占用的OFDM符号数量以及实际通信场景配置接收终端中保护间隔实际占用的OFDM符号数量。由于根据符号长度以及实际通信场景确定接收终端中自动增益控制实际占用的符号数量和/或保护间隔实际占用的符号数量，配置方式比较灵活，适用于各类场景。
可选地，本申请实施例中，时长配置装置至少可以是配置设备、接收终端，其中配置设备为除接收终端以外的第三方设备。当时长配置装置为配置设备时，配置设备根据子载波间隔信息确定自动增益控制占用的时长信息和/或保护间隔占用的时长信息之后，可以将自动增益控制占用的时长信息和/或保护间隔占用的时长信息发送至接收终端实现对接收终端的时长配置，也可以采用隐式指示的方式实现对接收终端的时长配置。当时长配置装置为接收终端时，接收终端在根据子载波间隔信息确定自动增益控制占用的时长信息和/或保护间隔占用的时长信息之后，直接对自身进行时长配置。由于根据子载波间隔设置情况对自动增益控制占用的符号数量和/或保护间隔占用的符号数量进行配置，而不是将自动增益控制和/或保护间隔配置为固定占用一个符号，故在子载波间隔变化，可以保证有足够的时间完成自动增益控制和/或保护间隔，避免了时频资源的浪费，提高了数据传输的误码率性能和资源利用性能。
下面具体对时长配置装置为配置设备、时长配置装置为接收终端这两种情况进行具体说明。
图5示例性示出了本申请实施例提供了一种时长配置方法的流程，该方法的流程可以由配置设备执行，包括以下步骤：
步骤S501，配置设备获取子载波间隔信息。
步骤S502，根据子载波间隔信息确定自动增益控制占用的时长信息和/或保护间隔占用的时长信息。
步骤S503，将自动增益控制占用的时长信息和/或保护间隔占用的时长信息发送至接收终端。
可选地，时长信息包括但不限于OFDM符号数量信息、Ts信息。
在一种可能的实施方式中，配置设备为基站，基站通过空口信令将自动增益控制占用的时长信息和/或保护间隔占用的时长信息发送至接收终端。具体实施中，基站可以通过广播消息通知接收终端后续数据传输所采用的自动增益控制和/或保护间隔占用的符号数量。基站也可以通过物理下行控制信道 (Physical Downlink Control Channel，简称PDCCH)中的动态下行控制信息(Donlink Control Information，简称DCI)信令通知终端后续数据传输所采用的自动增益控制和/或保护间隔占用的符号数量。基站还可以通过无线资源控制(Radio Resource Control，简称RRC)信令通知接收终端后续数据传输所采用的自动增益控制和/或保护间隔占用的符号数量。示例性地，如图6所示，终端1和终端2进行Sidelink数据通信之前，基站发送空口信令通知终端1和终端2后续数据传输所采用的自动增益控制和/或保护间隔占用的符号数量。
在另一种可能的实施方式中，配置设备为发送终端，发送终端通过直通链路Sidelink信令将自动增益控制占用的时长信息和/或保护间隔占用的时长信息发送至接收终端。具体实施中，发送终端通过Sidelink广播消息通知接收终端后续数据传输所采用的自动增益控制和/或保护间隔占用的符号数量。发送终端也可以通过Sidelink动态信令通知接收终端后续数据传输所采用的自动增益控制和/或保护间隔占用的符号数量。发送终端还可以通过Sidelink半静态信令通知接收终端后续数据传输所采用的自动增益控制和/或保护间隔占用的符号数量，发送终端还可以通过近距离通信端口5(Proximity Communication Port 5，简称PC5)信令通知接收终端后续数据传输所采用的自动增益控制和/或保护间隔占用的符号数量。示例性地，如图7所示，终端1为发送终端，终端2为接收终端，终端1和终端2进行Sidelink数据通信之前，终端1发送Sidelink信令通知终端2后续数据传输所采用的自动增益控制和/或保护间隔占用的符号数量。由于配置设备根据子载波间隔信息灵活配置接收终端自动增益控制和/或保护间隔占用的符号数量，可以进行动态或半静态调整，简单直接，而不是将自动增益控制和/或保护间隔占用的符号数量固定为一个符号，从而保证有足够的时间完成自动增益控制和/或保护间隔，提高了Sidelink数据传输的误码率性能和资源利用性能。
图8示例性示出了本申请实施例提供了一种时长配置方法的流程，该方法的流程可以由接收终端执行，包括以下步骤：
步骤S801，接收终端获取子载波间隔信息。
步骤S802，根据子载波间隔信息确定自动增益控制占用的时长信息和/或保护间隔占用的时长信息。
可选地，时长信息包括但不限于OFDM符号数量信息、Ts信息。
可选地，接收终端根据子载波间隔信息查询一种对照表，确定自动增益控制占用的时长信息和/或保护间隔占用的时长信息，一种对照表中预先保存了子载波间隔信息与自动增益控制占用的时长信息和/或保护间隔占用的时长信息之间的对应关系。
具体实施中，接收终端可以在开机后，自动读取存储在接收终端中的预先设定的对照表，比如表1，在获取子载波间隔信息时，按照表格中的对应关系，确定自动增益控制和/或保护间隔占用的符号数量，比如在获取子载波间隔为15kHz时，按照表1中的对应关系，确定自动增益控制占用一个符号，保护间隔占用一个符号。接收终端也可以在开机后，从基站侧读取基站下发的预先设定好的对照表，在获取然后子载波间隔信息时，按照表格中的对应关系，确定自动增益控制和/或保护间隔占用的符号数量。由于接收终端在获取子载波间隔信息后，根据预设的对照表确定自动增益控制和/或保护间隔占用的符号数量并进行时长配置，而不需要配置设备通过空口信令或Sidelink信令发送自动增益控制和/或保护间隔占用的符号数量对接收终端进行时长配置，故不需要占用空口信令或Sidelink信令，从而减少了开销。
