US 2006/0133268 A1 · Method and appartatus to improve communication performance in ARQ networks

Abstract

A wireless communication network improves reverse link communication performance by changing one or more Automatic Repeat Request (ARQ) control settings as a function of measured or estimated reverse link loading. Control settings can be changed on a per-sector basis, allowing consideration of different loading conditions in different radio sectors of the network. Further, control settings can be changed for individual mobile stations, or selected groups of mobile stations, allowing different ARQ controls to be used for different mobile stations. By way of non-limiting example, a control circuit in a base station controller can be configured to take advantage of light reverse link loading conditions in a given radio sector by changing the ARQ control parameter(s) used for one or more mobile stations operating in that sector so that fewer ARQ retransmissions are required for those mobile stations to transmit reverse link data to the network.

Dependent claims

A method of improving reverse link communication performance in a wireless communication network that uses Automatic Repeat Request (ARQ) control on a reverse link with one or more mobile stations, the method comprising:

detecting a reverse link loading condition as lightly loaded or normally loaded;
and
configuring the ARQ control for the one or more mobile stations according to first ARQ control settings during the normally loaded condition and according to second ARQ control settings during the lightly loaded condition, said second ARQ control settings being configured to reduce ARQ retransmissions by the one or more mobile stations during the lightly loaded condition.

A base station control circuit configured to improve reverse link communication performance in a wireless communication network that uses Automatic Repeat Request (ARQ) control on a reverse link with one or more mobile stations, the base station control circuit comprising one or more processing circuits configured to:

detect a reverse link loading condition as lightly loaded or normally loaded;
and
configure the ARQ control for the one or more mobile stations according to first ARQ control settings during the normally loaded condition and according to second ARQ control settings during the lightly loaded condition, said second ARQ control settings being configured to reduce ARQ retransmissions by the one or more mobile stations during the lightly loaded condition.

A method of improving the effective reverse link data rate of a mobile station transmitting to a wireless communication network on a reverse link under Automatic Repeat Request (ARQ) control by the network, the method comprising:

detecting a reverse link loading condition in a radio sector of the network in which the mobile station is operating;
and
changing one or more reverse link power control settings used by the ARQ control as a function of the detected reverse link loading condition to reduce ARQ retransmissions by the mobile station during light reverse link loading conditions.
