Abstract:
1. A method of performing a network entry at a mobile station (MS) in a wireless communication system, the method comprising: receiving, by the MS, an Advanced Air Interface Ranging Response (AAI-RNG-RSP) message from a base station (BS), wherein the AAI-RNG-RSP message includes an unsolicited bandwidth grant indicator, and wherein the unsolicited bandwidth grant indicator indicates that the BS will allocate a bandwidth to the MS within a predefined time and without receiving a bandwidth request from the MS during the network entry; after receiving the AAI-RNG-RSP message, monitoring, by the MS, an Advanced MAP Information Element (A-MAP IE) during the predefined time for a bandwidth allocation and without performing the bandwidth request; and transmitting a piggyback bandwidth request to the BS when an allocated bandwidth is not sufficient for transmission of a medium access control (MAC) message.
