Abstract: Embodiments of the present disclosure provide an encoding method for a traffic indication map and a beacon frame, which relate to a communication field, enable a user to know whether there are data cached in an access point or enable a user terminal to know whether to access to a channel, and reduce the quantity of bytes occupied by the traffic indication map in the beacon frame. The encoding method for a traffic indication map provided by the embodiments comprises: controlling whether to display a sub-block bitmap display field in a sub-bitmap by marking at least one bit in a bitmap control field, a sub-block sub-bitmap in the sub-bitmap being used for enabling a user terminal to know whether there are data cached in an access point, or enabling the user terminal to know whether to access to a channel.

Abstract translation: 本公开的实施例提供了一种用于与通信领域相关的业务指示图和信标帧的编码方法，使得用户能够知道是否存在高速缓存在接入点中的数据或使得用户终端能够知道是否访问 并且减少信标帧中的业务指示图所占用的字节数量。 由这些实施例提供的用于交通指示图的编码方法包括：通过在位图控制字段中标记至少一个比特来控制是否在子位图中显示子块位图显示字段，子块子位图 所述子位图被用于使用户终端能够知道是否存在在接入点中高速缓存的数据，或者使得用户终端知道是否访问信道。
