First Claim
1. In a wireless communication system, the communication system providing communication services for a plurality of mobile stations, wherein the plurality of mobile stations are in communication with a base station via a first communication resource, and wherein the base station is in communication with the plurality of mobile stations via a second communication resource, a method for controlling power during a dispatch group call, the method comprising:
- providing a power request authorization to at least one of the plurality of mobile stations based on a power requirement of each of the plurality of mobile stations;
monitoring for a transmission from the plurality of mobile stations via the first communication resource during a time period;
adjusting transmission power associated with the second communication resource based on the transmission from the plurality of mobile stations via the first communication resource;
determining whether the transmission power associated with the second communication resource is above a transmission power threshold; and
terminating transmissions to the plurality of mobile stations via the second communication resource in response to a failure to receive the transmission from the plurality of mobile stations via the first communication resource during the time period and a failure to detect the transmission power associated with the second communication resource being above the transmission power threshold.

Abstract
Preferred embodiments of a method and an apparatus for controlling power during a dispatch group call in a wireless communication system are described. A base station (142) monitors for a transmission from a plurality of mobile stations (270) via a first communication resource during a time period. The base station (142) adjusts transmission power associated with a second communication resource based on the transmission from the plurality of mobile stations (270) via the first communication resource. Further, the base station (142) determines whether the transmission power associated with the second communication resource is above a transmission power threshold. In response to a failure to receive the transmission from the plurality of mobile stations (270) via the first communication resource during the time period and a failure to detect the transmission power associated with the second communication resource being above the power threshold, the base station (142) terminates transmissions to the plurality of mobile stations (270) via the second communication resource.
