Patent ID: 8908714

Claim:
A selective discontinuous reception method on multiple component carriers, CCs, for a User Equipment, UE, at least one CC being configured with a Physical Downlink Control Channel, PDCCH, received from a base station of a radiocommunication network and arranged for scheduling resources on a physical shared channel to the UE on said at least one CC respectively and/or on at least one other CC, each CC having a respective active time within a discontinuous reception cycle during which the UE monitors or would monitor the reception of a PDCCH on said CC respectively if said CC is or was configured with a PDCCH, the method comprising: a determination step for determining whether at least one CC is configured with a PDCCH arranged for scheduling resources on at least one other CC; a discontinuous reception method selection step depending on an output of the determination step, in which: a) if at least one CC is configured with a PDCCH arranged for scheduling resources on at least one other CC which is not configured with a PDCCH, adjusting the active time of said at least one CC to the longest active time of said at least one CC and said at least one other CC; and b) otherwise, each CC being configured with a PDCCH arranged for scheduling resources only on said CC respectively, maintaining active times independent of each other for all CCs respectively.
