Abstract:
1. A method for wireless communications, comprising: communicating connection information that specifies one or more parameters of a connection between a base station and a wireless device, the connection information indicative of (i) a station identifier, (ii) whether data packets associated with the connection include a cyclic redundancy check, and (iii) whether data packets associated with the connection include encrypted information; constructing, based on the connection information, a media access control (MAC) protocol data unit (PDU) that includes a header comprising one or more bytes at a beginning portion of the MAC PDU, the header comprising: (i) a first flag that indicates a header type, (ii) a second flag that indicates whether there is a subheader inclusion following the header in the MAC PDU, (iii) a flow identifier that, together with the station identifier, identifies the connection, and (iv) a length value that indicates a length of the MAC PDU, wherein the header has a type that is selected based on a size of the MAC PDU to be one of a generic MAC header, a compact MAC header, and a signaling MAC header; including a subheader immediately following the header in the MAC PDU, wherein the second flag indicates a presence of the subheader, wherein the subheader includes a third flag that indicates whether, following the subheader in the MAC PDU, there is an inclusion of an additional subheader in the MAC PDU; and communicating the MAC PDU between the base station and the wireless device.
