摘要： Embodiments of the present invention 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 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.

摘要： A unit (25, 46) performs a compression operation or a decompression operation with respect to information for transmission in packets over a wireless link (36). The transmission over the wireless link is such that the packets may become reordered from a transmission sequence. The compression operation and the decompression operation involve a tradeoff of robustness and reordering depth. The robustness is an indicator of a degree of information loss over the link tolerated by the compression operation and the decompression operation; the reordering depth is a degree of packet reordering tolerated by the compression operation and the decompression operation. The unit dynamically adjusts the tradeoff of the robustness and the reordering depth in accordance with characteristics of the link. In an example embodiment, the information upon which the compression operation and the decompression operation is performed is sequence number information of a packet header.
