DC CAFCFirst Claim
1. A cellular telephone operable to communicate with a base station in a wireless communication system, the cellular telephone comprising:
- one or more processors having a Media Access Controller (MAC) operable to queue data pertaining to an uplink (UL) connection between the cellular telephone and the base station, the data associated with a respective priority; and
a transceiver operable totransmit an explicit message to the base station informing the base station that the cellular telephone has data awaiting transmission to the base station over the UL connection between the cellular telephone and the base station,subsequent to transmission of the explicit message, receive an indication of a first UL transmission resource, andtransmit information to the base station within the first UL transmission resource, the information indicative of an amount of data awaiting transmission to the base station over the UL connection between the cellular telephone and the base station.

Abstract
A method and apparatus for requesting and allocating bandwidth in a broadband wireless communication system. The method and apparatus includes a combination of techniques that allow a plurality of CPEs to communicate their bandwidth request messages to respective base stations. One technique includes a “polling” method whereby a base station polls CPEs individually or in groups and allocates bandwidth specifically for the purpose of allowing the CPEs to respond with bandwidth requests. The polling of the CPEs by the base station may be in response to a CPE setting a “poll-me bit” or, alternatively, it may be periodic. Another technique comprises “piggybacking” bandwidth requests on bandwidth already allocated to a CPE. Currently active CPEs request bandwidth using unused portions of uplink bandwidth that is already allocated to the CPE. The CPE is responsible for distributing the allocated uplink bandwidth in a manner that accommodates the services provided by the CPE.

6. A cellular telephone operable to communicate with a base station in a wireless communication system, the cellular telephone comprising:
-
one or more processors having a Media Access Controller (MAC) operable to queue data pertaining to a first uplink (UL) connection between the cellular telephone and the base station, the data associated with a respective priority; and a transceiver operable to transmit a message requesting the base station to poll the cellular telephone, in response to the message, receive an indication of a first UL transmission resource, transmit information to the base station within the first UL transmission resource, the information indicative of an amount of data awaiting transmission to the base station over the first UL connection between the cellular telephone and the base station, and receive, in downlink control information, an allocation of a second UL transmission resource for the cellular telephone in response to the information indicative of an amount of data awaiting transmission to the base station over the first UL connection between the cellular telephone and the base station. - View Dependent Claims (7, 8, 9)
