CONTROL SIGNALING OPTIMIZATION FOR LTE COMMUNICATIONS

摘要

The disclosure describes apparatus and methods for including downlink control information (DCI) normally associated with the physical downlink control channel (PDCCH) within a physical downlink shared channel (PDSCH) to reduce power consumption for a user equipment (UE) operating in a Long Term Evolution (LTE) radio resource control (RRC) connected mode. An enhanced NodeB base station can be configured to generate DCI associated with a future downlink resource assignment or uplink grant for the UE on the PDSCH or a physical uplink shared channel (PUSCH), and then include this DCI within the payload of a current PDSCH communication, such that the PDCCH does not need to be decoded by the UE during a time when DCI for future PDSCH communication is included within a current PDSCH.

主权项

1. A method for reducing power consumption at a user equipment (UE) communicating within a Long Term Evolution (LTE) network, the method comprising:
at a network base station:
generating downlink control information (DCI) indicating a future downlink resource assignment or uplink grant for the UE on a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH); andincluding the DCI indicating the future downlink resource assignment or uplink grant within a payload of a PDSCH communication,wherein a physical downlink control channel (PDCCH) does not need to be decoded by the UE for a period of time as a result of including the DCI indicating the future downlink resource assignment or uplink grant within the payload of the PDSCH communication.
