Resource Setting Control for Transmission Using Contention Based Resources
First Claim
1. A method comprisingcontrolling a transmission of a connection quality information from a user equipment to a base transceiver station via an uplink connection,setting resources of an uplink control channel for a plurality of user equipments, wherein resource elements of the resources of the uplink control channel are to be used for the transmission of the connection quality information by each of the plurality of user equipments,detecting a collision between transmissions of the connection quality information by at least two user equipments of the plurality of user equipments on a same resource element of the set resources of the uplink control channel, andexecuting a collision prevention processing when a collision is detected.

Abstract
There is proposed a mechanism for controlling a transmission of a connection quality information, like CQI, from a UE to a base transceiver station via an uplink connection. Resources of an uplink control channel for the trans-mission of the connection quality information are set for a plurality of UEs. A collision between transmissions of the connection quality information by at least two user equipments of the plurality of UEs on a same resource element is detected or predicted on the basis of input information, and a collision prevention processing is executed when such collision is detected or predicted.
