Description

配置信息的接收方法及装置 技术领域
本申请实施例涉及无线通信领域，尤其涉及一种配置信息的接收方法及装置。
背景技术
在通信系统中，终端或者中继站(以下简称终端)在接收信号时，周围的终端、中继站或者无线保真(wireless-fidelity，WiFi)设备产生的干扰信号，有时比该终端接收的信号的强度大几十个dB，会影响终端对信号的接收。为了减小干扰信号对终端要接收的信号的影响，终端需要对干扰信号进行测量得到干扰信号的到达角(direction of arrival，DOA)，并根据干扰信号的DOA以及接收信号的DOA对原始接收波束进行处理，形成零陷波束，并通过零陷波束接收信号。因为零陷波束存在主瓣和零陷点，零陷点的接收波束增益比主瓣的接收波束增益低30-50dB，所以，若终端在接收信号时将零陷点对准干扰信号方向，将主瓣对准要接收的信号的方向，可以实现对干扰信号的抑制，能更好的接收信号。例如，终端的原始接收波束通过干扰信号的DOA和接收信号的DOA处理后，形成的零陷波束可以如图1A所示。
目前，终端对干扰信号进行测量之前，接入点需要统计一段时间内的下行信道质量或者下行数据的丢包率，并根据统计结果确定终端是否需要测量干扰信号。接入点确定终端需要测量干扰信号后，向终端发送测量干扰信号的相关配置，终端接收到该配置后根据该配置测量干扰信号。上述过程中，接入点统计下行信道质量或者下行数据的丢包率是一个缓慢的过程，会导致触发终端测量干扰信号的时间较长。

结合第一方面，在第一种可能的实施方式中，该终端根据该第一配置信息测量干扰信号。基于上述方法，终端可以根据接入点配置的第一配置信息测量干扰信号，并根据测量结果形成零陷波束，以降低干扰信号对终端要接收的信号的影响。

第二方面，本申请实施例提供一种配置信息的接收方法，该方法包括：接入点接收来自终端的用于请求测量干扰信号的请求信息；该接入点根据该请求信息向该终端发送第一配置信息，该第一配置信息用于指示该终端测量干扰信号的时间长度。
基于上述第二方面的方法，接入点可以接收来自终端的请求信息，并根据请求信息为终端配置用于指示终端测量干扰信号的时间长度。在这个过程中，是终端发起的干扰测量请求。终端可以直接对下行信道进行测量，并且在下行信道质量不好的时候发起干扰测量请求，相比于接入点统计下行信道质量，终端对下行信道的变化感知更为及时，因此，可以缩短触发终端测量干扰信号的时间。
结合第二方面，在第一种可能的实施方式中，该第一配置信息包括该终端测量干扰信号的第一时间长度；或者，该第一配置信息包括测量周期，以及该测量周期内，该终端测量干扰信号的第二时间长度；或者，该第一配置信息包括该终端测量干扰信号的第一时间长度和该终端测量干扰信号的带宽；或者，该第一配置信息包括测量周期，该测量周期内，该终端测量干扰信号的第二时间长度，以及该终端测量干扰信号的带宽。基于上述方法，接入点可以向终端配置多种形式的第一配置信息，可以增强终端测量干扰信号的灵活性。

如图3所示，为本申请实施例提供的一种配置信息的接收方法，该配置信息的接收方法包括步骤301-步骤302。
步骤301：终端向接入点发送请求信息。
其中，该终端可以是图1B中的终端102-终端104中的任一终端。接入点可以是图1B中的接入点101。
其中，请求信息可以用于请求测量干扰信号。该请求信息可以命名为干扰测量请求(interference measurement request)或者其他名称，不予限制。
在一种可能的实现方式中，该请求信息包括终端请求测量干扰信号的时间长度。例如，该请求信息包括100毫米(ms)，表示终端请求测量干扰信号的时间长度为100ms。
在另一种可能的实现方式中，该请求信息包括干扰测量请求指示和终端请求测量干扰信号的时间长度。其中，干扰测量请求指示用于指示终端请求测量干扰信号。
可选的，该请求信息通过不同的帧格式发送给接入点。具体的，该请求信息可以至少通过如下两种可能的实现方式发送给接入点。
一种可能的实现方式，该请求信息包括在媒体接入控制(media access control，MAC)帧头中。例如，该请求信息携带在终端发送给接入点的受触发(trigger-based，TB)物理协议数据单元(physical protocol data unit，PPDU)的MAC帧头中，或者，该请求信息携带在终端发送给接入点的单用户(single user，SU)PPDU的MAC帧头中。
可以理解的，当该请求信息携带在TB PPDU的MAC帧头中时，步骤301之前，终端可以接收来自接入点的第二配置信息，该第二配置信息可以用于指示上行数据所在的资源。例如，第二配置信息用于指示以下资源中的至少一个：上行数据所在的时域资源、上行数据所在的频域资源、上行数据所在的空域资源或上行数据的调制与编码策略(modulation and coding scheme，MCS)等。可选的，第二配置信息可以携带在触发帧(trigger frame)中。
另一种可能的实现方式，该请求信息包括在MAC管理帧(MAC management frame)中。
示例性的，以该请求信息包括干扰测量请求指示和终端请求测量干扰信号的时间长度为例，该请求信息携带在终端发送给接入点的MAC管理帧中，该MAC管理帧可以如图4A所示。图4A中，该MAC管理帧包括17比特，其中，第一个比特(B0)用于指示终端请求测量干扰信号，第2到第17个比特(B1-B16)用于指示终端请求测量干扰信号的时间长度。
示例性的，以该请求信息包括终端请求测量干扰信号的时间长度为例，该请求信息携带在终端发送给接入点的MAC管理帧中，该MAC管理帧包括18比特，该18比特用于指示终端请求测量干扰信号的时间长度。
需要说明的是，上述MAC管理帧的长度、干扰测量请求指示在MAC管理帧中所占的长度，或者终端请求测量干扰信号的时间长度在MAC管理帧中所占的长度仅是示例性的，本申请实施例不对上述长度进行限制。
终端可以在以下情况下向接入点发送请求信息：
情况1：当终端检测到信号质量小于或等于第一阈值时，终端向接入点发送请求信息。
例如，终端检测到参考信号接收功率(reference signal received power，RSRP)、参考信号接收质量(reference signal received quality，RSRQ)、信号与干扰加噪声比(signal to interference plus noise ratio，SINR)或接收的信号强度指示(received signal strength indicator，RSSI)小于或等于第一阈值时，终端向接入点发送请求信息。
情况2：当终端检测到接收到的数据包的误块率(block error rate，BER)大于或等于第二阈值时，终端向接入点发送请求信息。
其中，接收到的数据包的BER为在终端接收到的传输块中，出错的传输块占的百分比。
情况3：当终端检测到干扰信号强度大于或等于第三阈值时，终端向接入点发送请求信息。
情况4：当终端检测到一段时间内，干扰信号的占空比大于或等于第四阈值时，终端向接入点发送请求信息。
其中，干扰信号的占空比为该一段时间内，终端检测到的干扰信号的时间的百分比。
可以理解的，上述情况1-情况4仅是示例性的，终端还可以在其他情况下向接入点发送请求信息，不予限制。
需要说明的是，本申请实施例不限制步骤301中终端的个数，该终端的个数可以是一个、两个或多个。
步骤302：接入点接收来自终端的请求信息，并根据请求信息向终端发送第一配置信息。
可选的，接入点接收来自终端的请求信息之后，向终端发送应答(acknowledgement，ACK)消息，该ACK消息指示接入点接收到该请求信息。
可选的，接入点根据请求信息向终端发送第一配置信息，包括：接入点根据请求信息确定第一配置信息；接入点向终端发送第一配置信息。
其中，第一配置信息用于指示终端测量干扰信号的时间长度。第一配置信息的介绍可以参考下述示例1-示例4：
示例1：第一配置信息可以包括终端测量干扰信号的第一时间长度。
可选的，第一时间长度和请求信息中终端请求测量干扰信号的时间长度相同或不同。
可以理解的，接入点可以根据当前的业务情况确定第一时间长度。例如，当前业务量较大，则第一时间长度小于或等于终端请求测量干扰信号的时间长度；当前业务量较小，则第一时间长度大于或等于终端请求测量干扰信号的时间长度。
示例2：第一配置信息可以包括测量周期，以及测量周期内，终端测量干扰信号的第二时间长度。
示例性的，以第一配置信息包括T1和T2，T1为测量周期，T2为第二时间长度为例，则接入点指示终端每隔T1对干扰信号进行测量，一个测量周期内，测量干扰信号的时间长度为T2。
可选的，第一配置信息还包括偏移时间长度。该偏移时间长度用于指示测量周期内，测量干扰信号的起始时间相对于测量周期的开始时间的偏移。该偏移时间长度大于或等于0，并且小于上述测量周期。
示例性的，以第一配置信息包括T1、T2和T3，T1为测量周期，T2为第二时间长度，T3为偏移时间长度为例，则接入点指示终端每隔T1对干扰信号进行测量，一个测量周期内，测量干扰信号的起始时间为该周期的起始时间以及偏移时间长度之和，测量干扰信号的时间长度为T2。例如，若某一个测量周期的起始时间为t1，第二时间长度为t2，偏移时间长度为t3，则对于该测量周期，接入点指示终端在t1+t3时刻开始测量干扰信号，并且测量干扰信号的时间长度为t2。
示例3：第一配置信息可以包括终端测量干扰信号的第一时间长度和终端测量干扰信号的带宽。
其中，终端测量干扰信号的带宽用于指示终端在该带宽内测量干扰信号。如此， 接入点可以在其他带宽内正常调度，降低了干扰测量对其他终端的正常业务调度的影响。第一时间长度的介绍可以参考上述示例1中所述，不予赘述。
示例4：第一配置信息可以包括测量周期，测量周期内，终端测量干扰信号的第二时间长度，以及终端测量干扰信号的带宽。
其中，终端测量干扰信号的带宽用于指示终端在该带宽内测量干扰信号。测量周期以及第二时间长度的介绍可以参考上述示例2中所述，不予赘述。
可选的，第一配置信息除了包括上述示例1、示例2、示例3或示例4中的内容之外，还包括反馈信息和/或第三时间长度。该反馈信息用于指示第一配置信息为该请求信息的反馈信息。例如，该反馈信息为干扰测量响应(interference measurement response)。第三时间长度为终端测量天线对应的每个接收波束的时间长度。
可以理解的，该第一配置信息可以在后续的下行传输中发送。
可选的，该第一配置信息通过不同的帧格式发送给终端。具体的，该第一配置信息可以至少通过如下两种可能的实现方式发送给终端。
一种可能的实现方式，该第一配置信息包括在MAC帧头中。例如，该第一配置信息携带在接入点发送给终端的SU PPDU的MAC帧头中。
另一种可能的实现方式，该第一配置信息包括在MAC管理帧中。
示例性的，以该第一配置信息包括反馈信息和第一时间长度为例，第一配置信息携带在接入点发送给终端的MAC管理帧中。该MAC管理帧可以如图4B所示。图4B中，该MAC管理帧包括17比特，其中，第一个比特(B0)用于指示第一配置信息为该请求信息的反馈信息，第2到第17个比特(B1-B16)用于指示第一时间长度。
示例性的，以该第一配置信息包括第一时间长度为例，该第一配置信息携带在接入点发送给终端的MAC管理帧中，该MAC管理帧包括18比特，该18比特用于指示第一时间长度。
需要说明的是，上述MAC管理帧的长度、反馈信息在MAC管理帧中所占的长度，或者第一时间长度在MAC管理帧中所占的长度仅是示例性的，本申请实施例不对上述长度进行限制。
可选的，接入点接收来自终端的请求信息后，确定哪些终端需要测量干扰信号。
一种可能的实现方式，接入点确定该终端需要测量干扰信号。
在这种情况下，接入点在向终端发送第一配置信息后，接入点停止与该终端之间的业务传输或者接入点停止所有的业务传输；或者，接入点在接收到来自终端的第一配置信息的ACK消息后，接入点停止与该终端之间的业务传输或者接入点停止所有的业务传输。
其中，接入点停止与该终端之间的业务传输是指接入点停止为该终端调度资源，停止向终端发送下行数据，也停止接收来自该终端的上行数据等。接入点停止所有的业务传输还可以替换为接入点停止与接入点连接的终端之间的业务传输。接入点停止所有的业务传输是指接入点停止为与接入点连接的所有终端调度资源，停止发送下行数据，也停止接收上行数据等。
可以理解的，若接入点停止所有的业务传输，可以减少周围的终端对该终端的影响，以提高该终端测量干扰信号的准确性。若接入点停止与该终端之间的业务传输， 虽然会影响该终端测量干扰信号的准确性，但是可以减少对与接入点连接的其他终端的业务的影响。
可选的，若接入点确定停止与该终端之间的业务传输，接入点在与该终端之间的业务量较小时，向该终端发送第一配置信息。若接入点确定停止所有的业务传输，接入点在接入点的业务总量较小时，向该终端发送第一配置信息。
另一种可能的实现方式，接入点确定与接入点连接的全部或部分终端需要测量干扰信号。
在这种情况下，接入点向与接入点连接的全部或部分终端发送第一配置信息。接入点向与接入点连接的全部或部分终端发送第一配置信息后，接入点停止所有的业务传输。其中，接入点停止所有的业务传输的介绍可以参考上述接入点确定该终端需要测量干扰信号时的描述，不予赘述。
可选的，接入点确定停止所有的业务传输，接入点在接入点的业务总量较小时，向与接入点连接的全部或部分终端发送第一配置信息。
需要说明的是，若接入点向与接入点连接的全部或部分终端发送第一配置信息，该第一配置信息包括在MAC帧头中，例如，该第一配置信息携带在接入点发送给终端的多用户(multi-user，MU)PPDU的MAC帧头中；或者，该第一配置信息包括在MAC管理帧中。该第一配置信息包括在MAC管理帧中的情况，可以参考接入点向步骤301中的终端发送第一配置信息的描述，不予赘述。
相应的，终端接收来自接入点的第一配置信息；或者，与接入点连接的全部或部分终端接收来自接入点的第一配置信息。
可选的，终端接收到来自接入点的第一配置信息后，向接入点发送第一配置信息的ACK消息。其中，该第一配置信息的ACK消息用于指示终端接收到该第一配置信息。
可选的，与接入点连接的全部或部分终端接收来自接入点的配置信息后，向接入点发送第一配置信息的ACK消息。其中，第一配置信息的ACK消息用于指示该终端接收到该第一配置信息。
基于图3所示的方法，终端可以向接入点发送用于请求测量干扰信号的请求信息，接入点接收到该请求信息后，可以根据该请求信息向终端发送用于指示终端测量干扰信号的时间长度的第一配置信息，以使得终端可以根据第一配置信息测量干扰信号。在这个过程中，是终端发起的干扰测量请求。终端可以直接对下行信道进行测量，并且在下行信道质量不好的时候发起干扰测量请求，相比于接入点统计下行信道质量，终端对下行信道的变化感知更为及时，因此，可以缩短触发终端测量干扰信号的时间。
进一步可选的，在图3所示方法的一种可能的实施方式中，终端根据第一配置信息测量干扰信号。具体的，如图5所示，图3所示的方法还包括步骤303：
步骤303：终端根据第一配置信息测量干扰信号。
可以理解的，第一配置信息包括的内容不同，终端根据第一配置信息测量干扰信号的过程不同：
对于上述示例1：若接入点在向终端发送第一配置信息后，停止与该终端之间的业务传输或者停止所有的业务传输，终端在接收到该第一配置信息后，开始测量干扰 信号，测量干扰信号的时间长度为第一时间长度。若接入点在接收到来自终端的第一配置信息的ACK消息后，停止与该终端之间的业务传输或者停止所有的业务传输，终端在向接入点发送第一配置信息的ACK消息后，开始测量干扰信号，测量干扰信号的时间长度为第一时间长度。
一种可能的实现方式，终端测量干扰信号，包括：终端在第一时间长度内，轮询扫描天线的接收波束，测量每个接收波束的干扰信号。
可选的，终端在每个接收波束上的测量时间为第三时间长度。该第三时间长度可以包括在第一配置信息中；或者，该第三时间长度预设置或存储在终端中。
相应的，接入点在向终端发送第一配置信息开始，停止与该终端之间的业务传输或者接入点停止所有的业务传输；或者，从接入点接收到来自终端的第一配置信息的ACK消息开始，接入点停止与该终端之间的业务传输或者接入点停止所有的业务传输。
可以理解的，干扰信号测量结束后，即从终端测量干扰信号开始，第一时间长度后，终端停止测量干扰信号。相应的，对于接入点，从接入点在向终端发送第一配置信息开始，第一时间长度后，接入点恢复与该终端之间的业务传输或者恢复所有的业务传输；或者，从接入点接收到来自终端的第一配置信息的ACK消息开始，第一时间长度后，接入点恢复与该终端之间的业务传输或者恢复所有的业务传输。
可选的，终端停止测量干扰信号，包括：终端停止扫描接收波束，恢复至默认接收波束。
对于上述示例2，若接入点在向终端发送第一配置信息后，停止与该终端之间的业务传输或者停止所有的业务传输，终端在接收到该第一配置信息后，周期性地测量干扰信号。若接入点在接收到来自终端的第一配置信息的ACK消息后，停止与该终端之间的业务传输或者停止所有的业务传输，终端在向接入点发送第一配置信息的ACK消息后，周期性地测量干扰信号。
其中，终端测量干扰信号的周期为第一配置信息中包括的测量周期，每个测量周期内，终端测量干扰信号的时间长度为第二时间长度。每个测量周期内，终端测量干扰信号的过程可以参考上述示例1中所述。
需要说明的是，若第一配置信息不包括偏移时间长度，终端在每个测量周期开始时就开始测量干扰信号。若第一配置信息包括偏移时间长度，终端在每个测量周期开始后，经过偏移时间长度后，开始测量干扰信号。
相应的，接入点在向终端发送第一配置信息开始，周期性地停止与该终端之间的业务传输或者周期性地停止所有的业务传输；或者，从接入点接收到来自终端的第一配置信息的ACK消息开始，接入点周期性地停止与该终端之间的业务传输或者周期性地停止所有的业务传输。
同理，若第一配置信息不包括偏移时间长度，接入点在每个测量周期开始时就停止与该终端之间的业务传输或者停止所有的业务传输。若第一配置信息包括偏移时间长度，接入点在每个测量周期开始后，经过偏移时间长度后，停止与该终端之间的业务传输或者停止所有的业务传输。
可以理解的，每个周期内，干扰信号测量结束后，终端停止测量干扰信号，接入点恢复与该终端之间的业务传输或者恢复所有的业务传输。具体的，可以参考上述示 例1中所述，不予赘述。
对于上述示例3，若接入点在向终端发送第一配置信息后，停止与该终端之间的业务传输或者停止所有的业务传输，终端在接收到该第一配置信息后，在终端测量干扰信号的带宽内，开始测量干扰信号，测量干扰信号的时间长度为第一时间长度。若接入点在接收到来自终端的第一配置信息的ACK消息后，停止与该终端之间的业务传输或者停止所有的业务传输，终端在向接入点发送第一配置信息的ACK消息后，在终端测量干扰信号的带宽内，开始测量干扰信号，测量干扰信号的时间长度为第一时间长度。
一种可能的实现方式，终端在终端测量干扰信号的带宽内，测量干扰信号，包括：终端在第一时间长度内，轮询扫描天线的接收波束，在终端测量干扰信号的带宽内，测量每个接收波束的干扰信号。

其中，终端测量干扰信号的周期为第一配置信息中包括的测量周期，每个测量周期内，终端测量干扰信号的时间长度为第二时间长度。每个测量周期内，终端测量干扰信号的过程可以参考上述示例3中所述。
需要说明的是，若第一配置信息不包括偏移时间长度，终端在每个测量周期开始时就在终端测量干扰信号的带宽内，开始测量干扰信号。若第一配置信息包括偏移时间长度，终端在每个测量周期开始后，经过偏移时间长度后，在终端测量干扰信号的带宽内，开始测量干扰信号。

可以理解的，每个周期内，干扰信号测量结束后，终端停止测量干扰信号，接入点恢复与该终端之间的业务传输或者恢复所有的业务传输。具体的，可以参考上述示例1中所述，不予赘述。
需要说明的是，若与接入点连接的全部或部分终端接收来自接入点的第一配置信息，则与接入点连接的全部或部分终端根据第一配置信息测量干扰信号。与接入点连接的全部或部分终端根据第一配置信息测量干扰信号的介绍，可以参考上述终端根据第一配置信息测量干扰信号中的描述，不予赘述。
基于图5所示的方法，终端可以根据接入点配置的第一配置信息测量干扰信号，以便后续根据测量结果形成零陷波束，以降低干扰信号对终端要接收的信号的影响。
