Method and apparatus in a telecommunications network for controlling uplink control channel
First Claim
1. A method of controlling resource utilization in a telecommunications network, wherein the telecommunications network comprises a plurality of mobile terminals and at least one radio base station, wherein the mobile terminals are configured to transmit messages to the radio base station over an uplink control channel, and wherein resources for said uplink control channel comprise a plurality of resource blocks, each resource block corresponding to a period of time and a frequency bandwidth, the method comprising:
- measuring an error rate of messages transmitted over the uplink control channel; and
on the basis of said measured error rate and one or more comparable thresholds, adapting a distribution of messages over said plurality of resource blocks on the uplink control channel by adapting the manner in which resource blocks transmitted by different mobile terminals are multiplexed onto the uplink control channel, wherein said adapting a distribution of messages comprises;
if the measured error rate is above the one or more thresholds, adapting the distribution of messages such that fewer messages are received over the uplink control channel in a given time interval, thereby reducing the error rate.

Abstract
The present invention provides a method and a radio base station (4) which actively monitor the error rate for messages transmitted over an uplink control channel between the radio base station (4) and one or more mobile terminals (6). The distribution of messages transmitted on the uplink control channel is then adapted in dependence on the measured error rate.
