Description

数据通信的方法和装置
本申请要求于2018年9月17日提交中国专利局、申请号为201811080226.1、申请名称为“数据通信的方法和装置”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
本申请涉及通信领域，更具体地，涉及一种数据通信的方法和装置。
背景技术
无线局域网(wireless local area network，WLAN)系统中，数据通信的流程通常为：接入点(access point，AP)发送触发帧，站点(station，STA)在接收到触发帧的短帧间间隔(short interframe interval，SIFS)时间之后，根据触发帧的指示发送上行物理层协议数据单元(physical protocol data unit，PPDU)，AP在接收到该PPDU之后，回复确认字符(acknowledgement，ACK)。其中，触发帧为一个控制帧，该控制帧包含时间指示的保护间隔(guard Interval，GI)，GI用于描述AP能够容忍的不同波束传输的信号到达接收端的时间差(时间偏移)的最大值。
在高频60GHz系统中，通常需要用户通过不同的模拟波束进行数据通信，来减小波束间的干扰。但是高频60GHz系统的带宽大，调制符号的符号时间短，或同步符号、参考信号时间短，对通过不同波束进行数据通信的时间不对齐容忍范围小。因此，在多个波束传输的信号到达接收端的时间差(时间偏移)大于保护间隔GI的情况下(即超出了容忍范围)，会对接收端的信号接收造成影响，从而使得数据通信的效率较低。
发明内容
本申请提供一种数据通信的方法和装置，能够有助于提高数据通信效率。
第一方面，提供了一种数据通信的方法，该方法包括：第一站点接收时间调整信息，该时间调整信息用于指示通过至少两个波束中的每个波束发送信号的发送时刻，该至少两个波束为至少一个站点对应的波束，该第一站点为该至少一个站点中的任意一个站点；该第一站点根据该时间调整信息，通过该至少两个波束中属于该第一站点的波束发送数据。
第一STA接收时间调整信息，该时间调整信息用于指示通过至少两个波束中的每个波束发送信号的发送时刻，第一STA可以根据该时间调整信息分别通过对应的波束在对应的发送时刻发送数据，使得AP能够同时接收到该至少一个站点通过该至少两个波束发送的数据，保证了数据的有效性，从而提高了数据通信效率。
在一些可能的实现方式中，该时间调整信息包括：通过该第一波束发送信号的发送时刻相对预设时刻的时间偏移，以及通过该至少两个波束中除第一波束之外的其他波束中的每个波束相对通过该第一波束的发送时刻的时间偏移。
通过该第一波束发送信号的发送时刻也可以是通过时间调整信息配置的，该时间调整信息还包括该第一站点通过第一波束发送信号的发送时刻的时间偏移，这样第一站点根据时间调整信息获知通过该第一波束发送信号的发送时刻。这样该至少一个站点在合适的时间分别通过对应的波束发送数据，且通过不同波束发送的数据能够同时到达接入点，从而保证了数据通信的有效性，提高了数据通信效率。
在一些可能的实现方式中，该时间调整信息包括：该至少一个站点中的第二站点发送信号的发送时刻相对预设时刻的时间偏移，以及通过该至少两个波束中的每个波束发送信号的发送时刻相对于该第二站点发送信号的发送时刻的时间偏移。

第一配置信息可以直接指示该至少两个波束，也可以是以扇区为单位指示该至少两个波束，每个扇区包括至少一个波束。也就是说，第一STA接收第一配置信息，在AP配置的波束上发送参考信号进行时间偏移的测量(该过程可以称为时间测量训练或波束训练)，这样STA配置AP指定的波束，并在AP指定的波束进行时间偏移的测量以及数据的传输，能够减少上行空间流的干扰，在提高传输效率的同时，保证通信质量。此外，该第二配置信息用于触发该站点发送用于进行时间测量的参考信号，即第一STA接收到该第二配置信息后立即启动发送参考信号的操作，例如，启动发送参考信号的操作可以是准备在一个时间间隔后发送参考信号。
在一些可能的实现方式中，该第一配置信息和该第二配置信息携带在同一个多波束配置帧中。第一配置信息和第二配置信息同时发送，相对于分别独立发送，节省了信令开销。
在一些可能的实现方式中，该第一站点接收第一配置信息和第二配置信息可以分别独立发送，即将天线模式设置和时间测量独立配置，也就是说，第一站点在完成天线模式设置之后，再进行上行波束训练，可以通过与触发帧更小的时间间隔，节省了测量时间偏移的时间间隔，从而降低了数据通信的时延。

下面对本申请涉及到的术语进行介绍。
波束成形：波束成形是一种由通信双方或多方为后续的通信过程实现必要传输链路预算的方法，即通过将发送或接收信号集中到接收机或发射机的波束方向上来增强信号，以选择信号质量较强或/和干扰较弱的波束进行通信，使得通信两端的通信信号质量得到改善。波束成形训练是一种双向的波束成形帧传输序列流程，通过波束扫描并提供必要信令，来使AP或STA决定用于发送或接收的合适的天线系统设置。
天线：天线通常是一个由相控阵构成的单个基本天线，或由一系列可切换波束天线构成的集合体，整体可构成一个伪全向的方向图。无论哪种实现方式，均可以动态配置为伪全向的方向图来进行发送或接收，还可以动态配置为对特定扇区或波束来进行发送或接收。
射频(radio frequency，RF)链：一个可以用于接收链或发送链的物理实体。通常由模数转换器(ADC)或数模转换器(DAC)起连接到天线。RF链可以用于进行上下变频、滤波、功率放大(例如低噪放大)等处理，进而将信号调整为适合射频天线发送的信号或将天线采集到的信号转化为适合采样和基带处理的信号。此外，当有N个RF链与N个天线一一对应连接时，例如，一个RF链仅固定连接到一个特定天线时，可以用RF链标识或天线标识对两者进行区别。
需要说明的是，由于RF链成本较高，而多个天线可以获得分集的效果，因此，可以由一个RF链动态配置连接到多个天线中的至少一个特定天线。
图1是本申请一个通信系统的示意图。图1中的通信系统可以包括一个AP和多个STA，其中，该多个STA具有模拟波束成形的能力。该多个STA并行接收或发送信号时，称为“多输入多输出(MU-MIMO)”。例如，一个AP在空域并行接收来自多个STA的信号时，称为上行MU-MIMO。当一个AP在空域并行发送信号到多个STA时，称为下行MU-MIMO。此外，该多个AP的天线可以联合向STA发送或接收，也可以构成MIMO。
图2是本申请另一个通信系统的示意图。站点需要基于信道情况对模拟波束和数字基带波束成形进行控制，以达到增强信号以及减少干扰的效果。具体地，对于数字基带波束成形，发送端数字基带到接收端数字基带间的信道取决于周围物理环境决定的物理信道，和模拟波束成形的波束方向。图2中的通信系统中，发送端数字基带可以输出多路信号，每一路信号输出到一个天线，例如具备波束成形能力的相控天线阵(phased antenna array，PAA)。
本申请实施例中，AP通过时间调整信息控制STA通过多个波束发送上行数据的发送时间，可以使得STA通过多个波束发送的信号到达AP的时间差控制在AP所能容忍的范围内，提升了数据通信的质量和效率。并能够有效克服在高频60GHz系统中，对通过不同波束进行数据通信的时间不对齐容忍范围小的问题，避免通过多个波束传输的信号到达 接收端的时间差大于GI的情况下(即超出了容忍范围)，会对接收端信号接收造成影响的问题。
可以理解的，本申请实施例的技术方案，既可以应用于AP与AP之间，还可以应用与AP与STA之间，还可以应用于STA与STA之间。为描述方便，本申请实施例以AP与STA之间的通信为例进行说明。
图3示出了本申请实施例的数据通信的方法的示意性流程图。
301，第一STA接收时间调整信息，该时间调整信息用于指示通过至少两个波束中的每个波束发送信号的发送时刻。相应地，AP发送该时间调整信息。
具体地，该至少两个波束是可以属于一个站点的波束，也可以为属于不同的站点的波束，本申请对此不进行限定。该第一STA可以是该至少一个站点中的任意一个站点，AP向该至少一个站点中的每个站点(例如第二STA、第三STA)发送该时间调整信息，该至少一个站点中的每个站点都可以如第一站点执行相应的动作，为方便描述，下述实施例以第一站点为例进行说明。也就是说，一个STA可被指示通过一个波束发送信号的发送时刻，还可以被指示通过多个波束发送信号的发送时刻。
需要说明的是，该时间调整信息可以显式指示该至少两个波束中的每个波束发送信号的发送时刻；该时间调整信息还可以是隐式指示该至少两个波束中每个波束发送信号的发送时刻，例如，该时间调整信息可以包括每个波束发送信号的发送时刻之间的关联关系或规则，本申请对此不进行限定。
还需要说明的是，1个波束或连续的多个波束可以组成一个扇区，本申请实施例中以波束为单位进行说明，该波束也可以替换为“扇区”，即以扇区为单位进行收发信号，本申请对此不进行限定。应理解，本申请实施例中的信号可以是参考信号，控制信号或数据，本申请对此不进行限定。还应理解，本申请实施例中，通过一个波束发送信号可以看作一个“空间流”，下述实施例对“波束”或“空间流”不进行区分。
302，第一STA根据该时间调整信息，通过该至少两个波束中属于该第一站点的波束发送数据。相应地，AP接收通过该至少两个波束发送的数据。
具体地，第一STA可以根据时间调整信息确定通过至少两个波束中的属于该第一STA的波束发送信号的发送时刻，第一STA可以根据该时间调整信息分别通过对应的波束在对应的发送时刻发送数据，使得AP能够同时接收到该至少一个站点通过该至少两个波束发送的数据，保证了数据的有效性，从而提高了数据通信效率。
需要说明的是，该时间调整信息可以包括每个波束的标识，通过波束的标识区分该多个波束中每个波束对应的发送时刻。例如，该至少两个波束可以采用统一的编号作为波束标识。在该至少两个波束属于至少两个站点的情况下，每个站点对应的波束可以分别进行编号，这样该时间调整信息可以包括波束所属的站点的标识(例如，称为STA指示)和波束的标识，以区分不同的波束。可选地，该STA指示可以通过至少一个比特位表示。例如，通过比特位图(bitmap)指示STA的媒体访问控制(media access control，MAC)地址、或指示与站点关联的AP的关联标识符(association ID，AID)、或指示为AP分配的用户组中的用户。
或者，该时间调整信息指示的通过该至少两个波束发送信号的发送时刻可以按照预设规则进行排序，这样该时间调整信息可以不包括波束标识，根据该预设规则就能够识别出 每个波束对应的发送时刻。
还需要说明的是，通过每个波束各自对应的发送时刻发送数据还可以是通过该至少两个波束中的每个波束在同一时刻发送目标信号，若未到达该波束对应的发送数据的发送时刻可以先发送其他信号，即该至少两个波束可以在指示的发送时刻启动发送目标信号，通过其他信号填充时间偏移，在到达该波束对应的目标信号的发送时刻时再进行发送，从而保证通过不同波束发送的目标信号同时到达AP，进而保证数据的有效性。
应理解，本申请实施例中，AP“同时接收”可以是AP“在预设时间差阈值范围内能够接收到的数据”，该预设时间差阈值范围可以是AP所能够容忍的时间差的上限，例如保护间隔GI，或，小于GI的其他值，该预设时间差阈值可以是AP与各个站点预先约定的，也可以是AP灵活设定，并告知各个站点，本申请对此不进行限定。
还应理解，该至少一个STA根据时间调整信息通过属于自己的波束可以发送数据，也可以发送其他信号，例如参考信号，本申请对此不进行限定。
可选地，该时间调整信息可以包括通过该至少两个波束中的除第一波束外的每个波束相对于该第一波束的发送时刻的时间偏移。
具体地，通过该第一波束的发送信号的发送时刻可以是预先设定的；或者通过该至少两个波束中的任意一个波束发送信号的发送时刻是预先是设定的，根据通过该任意的波束的发送信号的发送时刻可以确定通过该第一波束的发送信号的发送时刻。这样该至少一个站点在合适的时间分别通过对应的波束发送数据，且通过不同波束发送的数据能够同时到达接入点，从而保证了数据通信的有效性，提高了数据通信效率。
需要说明的是，该第一波束可以是第一站点对应的波束，也可以是其他站点对应的波束，本申请对此不进行限定。为描述方便，下述以第一波束为第一站点对应的波束为例进行说明。
还需要说明的是，该第一波束可以是该至少两个波束的任意一个波束，更具体地该第一波束可以是从所属的站点到接入点发送信号的传输时间最短的波束，也可以是发送信号的传输时间最长的波束，还可以是发送信号的传输时间处于中间值的波束。相应地，若第一波束为发送信号的传输时间最短的波束，则时间调整信息中的时间偏移均为正整数；若第一波束为发送信号的传输时间最长的波束，则时间调整信息中的时间偏移均为负整数；若该第一波束为发送信号的传输时间处于中间值的波束，则时间调整信息中的时间偏移包括正整数或负整数。
应理解，通过不同波束发送信号的发送时刻相对于其他波束发送信号的发送时刻的时间偏移的粒度可以相同，也可以不相同，本申请对此不进行限定。
可选地，该时间调整信息还可以包括通过该至少两个波束中的第一波束发送信号的发送时刻相对于预设时间的第一时间偏移。
具体地，通过该第一波束发送信号的发送时刻也可以是通过时间调整信息配置的，该时间调整信息包括该第一站点通过第一波束发送信号的发送时刻的时间偏移，这样第一站点根据预设时刻和通过该第一波束发送信号相对该预设时刻的时间偏移能够获知通过该第一波束发送信号的发送时刻。
需要说明的是，本申请中的预设时刻可以是协议约定的触发上行的时间间隔之后的固定时刻，或者是上次进行数据通信所使用的发送时刻或上次进行数据通信所使用的发送时 刻相对固定时刻的时间偏移，本申请对此不进行限定。
应理解，本申请实施例中，该时间调整信息携带的时间偏移的数目与波束的数目可以是一一对应的。
可选地，该时间调整信息可以是通过时间调整信息字段携带在多波束反馈帧中，由AP发送给STA的。
具体地，该时间调整信息字段可以包括通过每个波束发送信号的发送时刻，或者该多波束反馈帧包括第一波束相对预设时刻的时间偏移，以及该至少两个其他波束相对于该第一波束的时间偏移。
例如，如图4所示，波束0表示第一波束，其他波束分别编号为波束1、波束2，…，波束i，该时间调整信息字段可以包括通过每个波束发送信号的发送时刻，例如波束0发送信号的发送时刻(time advance for beam 0)。即，如图1所示STA1和STA2对应的波束统一编号为波束0，波束1，…，波束5，其中，第一波束可以是该6个波束中的任意一个波束。
例如，如图5所示，以波束0表示第一波束，其他波束分别编号为波束1、波束2，…，波束i，该时间调整信息字段可以包括波束0相对预设时刻的时间偏移(time advance offset for beam 0)，其他波束相对于第一波束的时间偏移(time advance offset for beam i)。
需要说明的是，该时间调整信息字段中还可以包括每个波束的波束标识(例如，波束索引(beam index))用于区分每个波束对应的发送时刻或时间偏移。此外，该时间调整信息字段中还可以包括该至少两个波束的总数目(number of beams)。
还需要说明的是，图4或图5中波束索引连续顺序排序，全部排序之前为连续的每个波束索引对应的发送时刻，或全部排序之后为连续的每个波束索引对应的时间偏移。本申请实施例中，图4可以是每个波束索引与该波束索引对应的发送时刻相邻，图5可以是每个波束索引与该波束索引对应的时间偏移相邻。
应理解，该多波束反馈帧也可以是多波束配置帧(MIMO configuration frame)I，还可以是“时间测距(ranging)帧”，或能够进行时间对齐指示的其他帧，或能够进行测量时间传播延迟的其他帧。
可选地，该时间调整信息包括该至少一个站点中的第二站点发送信号的发送时刻相对于预设时刻的时间偏移，以及该至少两个波束中的每个波束相对于该第二站点发送信号的发送时刻的时间偏移。
具体地，该第二站点发送信号的发送时刻为通过该第二站点对应的波束发送信号的发送时刻的等效时刻(例如，可以是该第二站点对应的至少两个波束发送信号的发送时刻的平均值)。该时间调整信息中携带一个第二站点发送信号的发送时刻相对预设时刻的时间偏移，这样第一站点能够获知第二站点发送信号的发送时刻。该时间调整信息还携带该至少两个波束中的每个波束相对于该第二站点发送信号的发送时刻的时间偏移，这样第一站点根据第二站点发送信号的发送时刻可以获知通过每个波束发送信号的发送时刻，从而第一站点能够在合适的时刻分别通过对应的波束发送数据，保证通过不同波束的数据到达接入点的对齐，即保证了数据通信的有效性，提高了数据通信效率。
应理解，该第二站点可以是该至少一个站点中的任意一个站点，且第二站点可以与第一站点为同一个站点，也可以是不同的站点，本申请对此不进行限定。
可选地，该时间调整信息包括该至少两个波束中每个波束发送信号的发送时刻相对于预设时间的时间偏移，这样第一站点可以根据该时间调整信息确定该至少两个波束中每个波束发送信号的发送时刻，从而保证了通过不同波束发送的数据到达接入点的时间对齐，提高了数据通信效率。
可选地，时间偏移可以通过时间调整信息中的一个时间偏移字段表示。
具体地，该时间偏移字段到时间偏移可以是均匀映射，也可以是非均匀映射。非均匀映射可以理解为时间偏移字段的不同取值指示的时间偏移可以相同，也可以不同。时间偏移字段的取值从小到大对应的时间偏移可以越来越小，也就是说，当使用非均匀间隔的映射时，对于时间偏移字段的取值的绝对值较大时对应的时间偏移越小。例如，时间偏移字段为2bit，该时间偏移字段的取值可以是0,1,2,3，且0对应10ms，1对应1ms，2对应100us，3对应1us，这样对于时间偏移字段取值越大，时间偏移字段指示的时间偏移越小，即通过时间偏移字段的较小取值进行大幅度调节时间偏移，通过时间偏移字段的较小取值进行微调时间偏移。
可选地，该时间调整信息还可以包括视距(line of sight,LoS)标识。
具体地，当协议最大支持2 k个空间流时，LoS标识可以通过LoS指示字段表示，LoS字段可以为k个bit，即可以映射到1～2 k个空间流编号，这样时间调整信息可以通过LoS指示字段指示的空间流编号确定对应的LoS径。
可选地，该时间调整信息还可以包括指示LoS径的传播时延的字段，即时间调整信息可以通过额外的字段指示LoS径的传播时延。
可选地，该时间调整信息指示的时间偏移与传输路径的传输时延可以具有对应关系。该时间调整信息可以通过时间偏移指示LoS径的传播时延，这样避免占用额外的字段，节省了信令开销。
可选地，第一STA在接收时间调整信息之前，还可以接收第一配置信息和第二配置信息，该第一配置信息用于指示该至少两个波束，该第二配置信息用于触发站点发送用于进行时间测量的参考信号，第一STA根据该第二配置信息，通过该至少两个波束发送该参考信号。相应地，AP发送该第一配置信息和该第二配置信息，以及接收参考信号，并通过测量参考信号得到时间调整信息。
具体地，第一配置信息可以直接指示该至少两个波束，也可以是以扇区为单位指示该至少两个波束，每个扇区包括至少一个波束。也就是说，第一STA接收第一配置信息，在AP配置的波束上发送参考信号进行时间偏移的测量(该过程可以称为时间测量训练)，这样STA配置AP指定的波束，并在AP指定的波束进行时间偏移的测量以及数据的传输，能够减少上行空间流的干扰，在提高传输效率的同时，保证通信质量。此外，该第二配置信息用于触发该站点发送用于进行时间测量的参考信号，即第一STA接收到该第二配置信息后立即启动发送参考信号的操作，例如，启动发送参考信号的操作可以是准备在一个时间间隔后发送参考信号。
需要说明的是，站点通过不同的波束发送参考信号，使得AP根据参考信号进行时间偏移的测量具体可以是站点通过同一时刻发送参考信号，AP根据接收到参考信号的接收时刻确定采用不同波束发送参考信号的时间偏移量。其中，站点发送的参考信号中可以用于指示对应波束的波束标识信息，以使得AP能够识别不同波束。
或者，站点通过不同波束发送参考信号，每个参考信号中携带发送时刻，这样AP能够根据每个参考信号中携带的发送时刻确定出站点采用不同波束发送信号的发送时刻的时间偏移。
还需要说明的是，该第一配置信息和第二配置信息可以分别发送，例如，站点接收到第一配置信息进行配置之后，AP再发送第二配置信息来触发站点发送参考信号，这样可以根据站点配置的时间进行参考信号的时间测量训练，从而节省了时间测量训练的时间。
可选地，该第一配置信息还可以包括UL功率指示或传输带宽/采样率/时间粒度指示。UL功率指示可以指示AP期望的接收每空间流的信号功率、指示AP期望接收的每个用户的上行信号功率、指示AP期望的接收每空间流的分别的信号功率、指示AP期望的接收每上行用户的分别的信号功率中的至少一项；传输带宽/采样率/时间粒度指示可以指示上行PPDU的带宽格式，例如2.16GHz或4.32GHz或8.64GHz或协议指定的其他带宽模式。若该PPDU被进行频域划分成多个资源块被分配给多个STA传输，还可包含各STA使用的资源块大小和频域位置。其中，当带宽越大时，采样率越大，时间粒度越小。
可选地，该第一配置信息还可以包括STA使用的天线扇区配置指示，该天线扇区配置指示可以包括发射天线标识(identity，ID)、发射波束ID(或发射扇区ID)、倒计数序号值(counting down，CDOWN)、天线加权向量(antenna weight vector，AWV)ID。可选地，该第一配置信息还可以包括AP接收所用的接收天线ID、接收波束ID(接收扇区ID)、AWV ID中的一个或多个。
应理解，CDOWN用于指示一串往各自波束方向发送的帧的帧倒计数序号值。AWV用于指示天线加权向量，当天线上的多个阵元采用不同的天线加权向量时，天线所发送或接收的波束图样是不同的(指定方向上的增益系数不同)。
可选地，该第一配置信息和第二配置信息可以携带在同一个用于训练的多天线配置帧(MIMO configuration frame for training)中，例如，如图6所示。
具体地，第一配置信息和第二配置信息携带在一个帧中发送，相对于分别独立发送，节省了信令开销。
可选地，该第一配置信息还可以包括会话标记字段。
具体地，该会话标记字段用于指示AP的每个接收天线，具体地可以是通过会话标记字段的取值指示会话标记，再通过会话标记指示接收天线。例如，会话标记字段可以指示当前传输的多天线配置帧所在会话的标记(token)；或该会话标记字段指示天线扇区配置指示包括的波束ID对应的携带参考信号的帧所属的会话的标记。
需要说明的是，携带参考信号的帧可以是多波束训练帧(MIMO training frame)。
可选地，该第一站点可以接收波束细化协议(beam refinement protocol，BRP)反馈帧，所述BRP反馈帧包括新增字段，所述新增字段用于指示该时间调整信息。
具体地，该新增字段可以是以训练单元为单位的，每个训练单元可以是不同波束、不同扇区或不同AWV方向，此外，每个训练单元可以包括多路时域正交的训练信号，每路训练信号可往不同的方向发送。本申请实施例能够在现有协议的BRP反馈帧中进行较小的改动实现指示该时间调整信息，从而节省了开销，以及提高了兼容性。
例如，如图7所示，该BRP反馈帧包括BRP反馈标识(BRP MIMO feedback)、反馈类型(feedback type)，以及时间调整信息字段，该时间调整信息字段可以如图4或图 5。其中，反馈类型可以是用于指示该BRP反馈帧中是否包括时间调整信息字段。
可选地，在该时间调整信息通过BRP反馈帧携带的情况下，第一配置信息可以是通过BRP配置帧中新增字段携带，相应地，参考信号也可以携带在BRP帧中，例如，如图8所示。
可选地，该第一站点接收第一配置信息和第二配置信息可以分别独立发送，即将天线模式设置和时间测量独立配置，也就是说，第一站点在完成天线模式设置之后，再进行上行波束训练，可以通过与触发帧更小的时间间隔，节省了测量时间偏移的时间间隔，从而节省了数据通信的时延。
可选地，该第一配置信息和第二配置信息独立发送可以是在请求发送(request to send,RTS)帧中，或者在确认发送(confirm to send，CTS)帧中携带该第一配置信息。
具体地，该第一站点接收RTS帧，并根据该RTS帧中携带的第一配置信息进行天线模式配置。或者该第一站点接收CTS帧，并根据该CTS帧中携带的第一配置信息进行天线模式配置，如图9所示。
需要说明的是，在AP发送RTS帧的情况下，STA也可以反馈CTS用于指示是否接收成功。
可选地，第一STA接收触发信息，该触发信息用于触发STA发送数据。相应地，AP发送该触发信息。具体地，第一STA在接收到时间调整信息之后，获知不同波束发送信号的时间偏移，该第一STA还可以在接收触发信息之后，发送数据，例如，如图6所示。
需要说明的是，本申请实施例中，在预设时刻阈值内，考虑到时间偏移的变化并不明显的情况下，AP可以在发送时间调整信息之后，在需要进行数据通信时，只发送触发信息，即时间调整信息与触发信息的数目不同。
可选地，该时间调整信息和该触发信息携带在同一个多波束反馈帧中。
具体地，触发信息用于触发第一STA发送数据，该时间调整信息和该触发信息可以携带在一个多波束反馈帧，该多波束反馈帧也可以称为多波束配置帧(MIMO Configuration frame)I中，例如，如图10所示。这样，AP可以对该至少两个波束的时间偏移进行持续跟踪调整，从而更进一步提高了数据通信效率。
因此，本申请实施例的数据通信的方法，第一STA接收用于指示通过至少两个波束中的每个波束发送信号的发送时刻的时间调整信息，可以根据该时间调整信息分别通过对应的波束在对应的发送时刻发送数据，使得AP能够同时接收到该至少一个站点通过该至少两个波束发送的数据，保证了数据的有效性，从而提高了数据通信效率。

应理解，在本申请的各种实施例中，上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
