Method and apparatus to improve discontinuous reception (DRX) operation for TDD (time division duplex) and FDD (frequency division duplex) mode in carrier aggregation (CA)

摘要

A method and apparatus are disclosed for performing DRX (Discontinuous) operation. In one embodiment, the method comprises (i) configuring a plurality of cells for carrier aggregation, (ii) configuring the plurality of cells with a plurality of TDD (Time Division Duplex) UL-DL (Uplink-Downlink) configurations, (iii) configuring the plurality of cells for DRX operation, (iv) configuring a set of DRX timers for the plurality of cells, and (v) running the set of DRX timers for the plurality of cells.

1. A method for performing DRX (Discontinuous Reception) operation, comprising:
configuring a plurality of cells for carrier aggregation; configuring the plurality of cells with a plurality of TDD (Time Division Duplex) UL-DL (Uplink-Downlink) configurations; configuring the plurality of cells for DRX operation; configuring a set of DRX timers for the plurality of cells; and running the set of DRX timers for the plurality of cells; wherein a RRC (Radio Resource Control) message indicates and selects a cell in the plurality of cells that should be used to find a next PDCCH (Physical Downlink Control Channel) subframe to run the set of DRX timers.
