Abstract:
1. An apparatus comprising: a wireless device to categorize a mobile station in a multi-user group according to one or more of a requested modulation and coding scheme (MCS), reported channel condition, or scheduling consideration, to assign one of a plurality of multi-user Medium Access Protocol (MAP) Information Elements (MU-MAP_IEs) comprised within a downlink MAP (DL-MAP) to the multi-user group, to encapsulate a plurality of user data payloads using the same MCS into a multi-user payload field in a multi-user packet data structure to be simultaneously scheduled and transmitted over a downlink transport connection to the mobile station, the assigned MU-MAP_IE to address the plurality of user data payloads in the multi-user payload field, to establish a transport connection to each mobile station included in the multi-user group, to assign a connection identifier (CID) to each transport connection where each of the assigned CIDs comprises a same most significant bit portion, and to assign an m-bit compact connection identifier (CCID) value to each transport connection, the m-bit CCID value for each transport connection having a fewer number of bits than the CID for that transport connection and comprising a least significant bit portion of the connection identifier for that transport connection, the multi-user packet data structure comprising a multi-user MAC header and one of a multi-user frame check sequence (MFCS) field or a multi-user header check sequence (MHCS) field, the MFCS field to include a cyclic redundancy check (CRC) value calculated for the entire multi-user packet data structure including the multi-user MAC header and the plurality of user data payloads included in the multi-user payload field, the MHCS field to include a CRC value calculated for only the multi-user MAC header.
