Selective discontinuous reception method and related system and device

摘要

Selective DRX method on multiple CCs for a UE (320), at least one CC being configured with a PDCCH received from a base station (310) 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 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. It is determined whether at least one CC is configured with a PDCCH arranged for scheduling resources on at least one other CC. If it is, the active time of said at least one CC is adjusted to the longest active time of said at least one CC and said at least one other CC. Otherwise, independent active times are maintained for all CCs respectively.

1. 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.
