Dynamic control of transmission of reverse-link control signals

摘要

A method and system for dynamically controlling the transmission of reverse-link control signals to help reduce interference on the reverse link. A RAN identifies a mobile device whose transmission of reverse-link control signals best represents the reverse-link air interface condition of each other mobile device in a plurality of mobile devices. Then the RAN causes each mobile device in the plurality other than the identified mobile device to not send its respective reverse-link control signal at a given time, thereby reducing the number of mobile devices that transmit reverse-link control signals at the given time.

1. In a wireless communication system in which a RAN provides service to a plurality of mobile devices over an air interface, a method of managing reverse-link control signal transmission from the mobile devices to the RAN, the method comprising:
(a) the RAN determining, for each mobile device in the plurality, a measure of how well a reverse-link control signal transmitted from the mobile device represents reverse-link air interface conditions of each other mobile device in the plurality; (b) the RAN identifying, from the plurality of mobile devices, a given mobile device whose determined measure is the best; and (c) the RAN causing, based on the identification of the given mobile device, each other mobile device in the plurality to not send the reverse-link control signal at one or more predetermined times.
