Enhanced node B, user equipment and methods for discontinuous reception in inter-eNB carrier aggregation

摘要

Embodiments of user equipment (UE) and methods for enhanced discontinuous reception (DRX) operations for inter eNB carrier aggregation (CA) in an LTE network are generally described herein. In some embodiments, a UE is configured to be served by multiple serving cells. The first set of the serving cells may be associated with a first eNB and a second set of serving cells may be associated with a second eNB. In these embodiments, DRX operations may be performed independently in multiple serving cells belonging to the different eNBs. Other embodiments for enhanced DRX operations are also described.

1. User equipment (UE) configured for enhanced discontinuous reception (DRX) operation in which the UE is configurable to be served by multiple serving cells, the UE comprising hardware processing circuitry include transceiver circuitry configured to:
receive first DRX parameters for DRX operations for serving cells of a first set, the first DRX parameters indicating identical DRX operations for the serving cells of the first set including a first active time; receive second DRX parameters for DRX operations for serving cells of a second set, the second DRX parameters indicating at least a second active time that is common for all serving cells of the second set; monitor a physical downlink control channel (PDCCH) of at least one of the serving cells of the first set during the first active time; monitor a PDCCH of at least one of the serving cells of the second set during the second active; wherein the hardware processing circuitry is configured to process resource blocks received from a first enhanced node B (eNB) and resource blocks received from a second eNB in accordance with a carrier aggregation (CA) technique when the active times are synchronized, wherein the serving cells of the first set are associated with the first eNB and the serving cells of the second set are associated with the second eNB; wherein the multiple serving cells include a primary cell (PCell) and one or more secondary cells (SCell), wherein the UE is further configured to monitor the PDCCH in different subframes for the serving cells associated with each of the eNBs to receive the DRX parameters.
