Abstract:
1. A method comprising the steps of: receiving, by a receiver, at least part of data packets and dedicated control information (DCI) destined for the receiver from a base station on a subset of selected resource unit candidates among a plurality of resource units defined on a shared data channel (SDCH), which are selected by the base station, a resource unit being a minimum unit for data allocation in a combination of time and frequency domains on the SDCH, the DCI including modulation and coding information of the data packets, wherein the DCI is mapped to a first slot of a resource unit candidate included in said subset of selected resource unit candidates and the at least part of the data packets is mapped to a second slot of the resource unit candidate which follows the first slot of the resource unit candidate, the first slot and the second slot being provided in a single resource unit candidate that is defined on the SDCH, and the SDCH being a data region which follows a control region in a time domain, wherein the control region is a shared control information region shared by all users, comprising resource unit allocation information; attempting, by the receiver, to decode the selected resource unit candidates to successfully decode the DCI destined for the receiver and transmitted on said subset of selected resource unit candidates to detect the at least part of the data packets; receiving, by the receiver, information related to the selected resource unit candidates from the base station before receiving the at least part of the data packets and the DCI; and signalling, by the receiver, a feedback message containing feedback information for use by the base station to select the resource unit candidates in next transmission, wherein the feedback information comprises a channel quality indicator (CQI) of the resource unit candidates.
