Abstract:
1. A base station comprising: media access control (MAC) layer circuitry to determine when a poll-me indicator is provided in a MAC header of uplink data packets of an established communication session received from a mobile station, the poll-me indicator indicating that additional bandwidth is being requested by the mobile station for the established communication session; and physical layer circuitry to transmit a bandwidth allocation message to the mobile station, wherein the mobile station refrains from using a contention channel to request an allocation information element when the mobile station is able to set the poll-me indicator in the MAC header of uplink packets, wherein the uplink data packets of the established communication session include a connection identifier associated with the mobile station, wherein the communication session established with the mobile station allows the mobile station to operate in a push-to-talk mode, wherein the mobile station transmits the MAC header with the poll-me indicator to the base station when a user initiates a transmission, and wherein upon receipt of a bandwidth allocation from the base station, the mobile station provides either an audio or visual indication to the user to either transmit or talk.
