The invention also relates to a corresponding method of decoding data packets, a transmitter, receiver and communication system. ## Claims ### Claim 1 A method of detecting data packets received by a receiver over a plurality of dynamically allocated resource units, the unit being a minimum unit for data allocation in a combination of time and frequency domains on a shared channel of a wireless communication system, the method comprising the steps of: receiving at least part of the data packets and dedicated control information (DCI) destined for the receiver from a transmitter on a subset of selected resource unit candidates, which are selected by the transmitter, the DCI including modulation and coding information of the data packets; and attempting to decode the selected resource unit candidates to successfully decode the DCI destined for the receiver and transmitted on said subset to detect the at least part of the data packets, wherein the step of receiving the at least part of the data packets and the DCI includes receiving the DCI that is mapped at a beginning first slot of said subset of the selected resource unit candidates and receiving the at least part of the data packets containing user data mapped at a second slot of said subset. ### Claim 2 (depends on 1) The method according to claim 1, further comprising a step of receiving information related to the selected resource unit candidates from the transmitter before receiving the at least part of the data packets and the DCI. ### Claim 3 (depends on 1) The method according to claim 1, wherein the step of attempting to decode the selected resource unit candidates is carried out in a parallel manner. ### Claim 4 (depends on 1) The method according to claim 1, wherein the step of attempting to decode the selected resource unit candidates is carried out in a serial manner with a priority scheme. ### Claim 5 (depends on 1) The method according to one of claim 1, further comprising a step of signalling a feedback message containing information for use by the transmitter to select the resource unit candidates. ### Claim 6 (depends on 1) The method according to claim 1, wherein the DCI carries an identifier of the receiver for use by the receiver in decoding the DCI destined for the receiver. ### Claim 7 (depends on 1) The method according to claim 1, wherein the DCI is modulated and encoded using at least one of a modulation parameter, coding parameter or transport parameter, which allows the receiver to distinguish the DCI destined therefor from those destined to other receivers. ### Claim 8 A receiver for receiving data packets over a plurality of dynamically allocated resource units, the unit being a minimum unit for data allocation in a combination of time and frequency domains on a shared channel of a wireless communication system, the receiver comprising one or more processors configured to perform the steps comprising: receiving at least part of the data packets and dedicated control information (DCI) destined for the receiver from a transmitter on a subset of selected resource unit candidates, which are selected by the transmitter, the DCI including modulation and coding information of the data packets; and attempting to decode the selected resource unit candidates to successfully decode the DCI destined for the receiver and transmitted on said subset to detect the at least part of the data packets, wherein the step of receiving the at least part of the data packets and the DCI includes receiving the DCI that is mapped at a beginning first slot of said subset of the selected resource unit candidates and receiving the at least part of the data packets containing user data mapped at a second slot of said subset. ### Claim 9 (depends on 8) The receiver according to claim 8, wherein the one or more processors are further configured to perform a step of receiving information related to the selected resource unit candidates from the transmitter before performing the step of receiving the at least part of the data packets and the DCI. ### Claim 10 (depends on 8) The receiver according to claim 8, wherein the one or more processors are configured to perform the step of attempting to decode the selected resource unit candidates in a parallel manner. ### Claim 11 (depends on 8) The receiver according to claim 8, wherein the one or more processors are configured to perform the step of attempting to decode the selected resource unit candidates in a serial manner with a priority scheme. ### Claim 12 (depends on 8) The receiver according to claim 8, wherein the one or more processors are further configured to perform a step of signalling a feedback message containing information for use by the transmitter to select the resource unit candidates. ### Claim 13 (depends on 8) The receiver according to claim 8, wherein the DCI carries an identifier of the receiver for use by the receiver in decoding the DCI destined for the receiver. ### Claim 14 (depends on 8) The receiver according to claim 8, wherein the DCI is modulated and encoded using at least one of a modulation parameter, coding parameter or transport parameter, which allows the receiver to distinguish the DCI destined therefor from those destined to other receivers.
