Control signaling optimization for LTE communications
First Claim
1. A method for reducing power consumption by a user equipment (UE) communicating within a cellular wireless network, the method comprising:
- by a network apparatus of the cellular wireless network;
generating downlink control information (DCI) that indicates a future resource assignment for the UE on a physical downlink shared channel (PDSCH); and
sending, to the UE at a static reserved resource block location or at a dynamic resource block location, the DCI in a PDSCH payload;
wherein;
inclusion of the DCI in the PDSCH payload allows the UE to refrain from decoding a physical downlink control channel (PDCCH) until after receipt of the DCI via the PDSCH.

Abstract
The disclosure describes procedures for allocating network resources for a mobile device communicating within a Long Term Evolution (LTE) network. The mobile device can be configured to decode a physical downlink shared channel (PDSCH), acquire first and second physical downlink control channel (PDCCH) decode indicators from a payload of the same PDSCH communication, decode a PDCCH for downlink control information (DCI) associated with a first application data type based on the first PDCCH decode indicator a second application data type based on the second PDCCH decode indicator. The first PDCCH decode indicator can identify an upcoming LTE subframe where the mobile device is required to decode the PDCCH for DCI associated VoLTE resource assignments and the second PDCCH decode indicator can identify an upcoming LTE subframe where the mobile device is required to decode the PDCCH for DCI associated with high bandwidth best effort (BE) data resource assignments.

10. A network apparatus, comprising:
-
one or more transceivers configurable to communicate via a cellular wireless network; one or more processors communicatively coupled to the one or more transceivers; and a storage device communicatively coupled to the one or more processors and storing instructions that, when executed by the one or more processors, cause the network apparatus to perform actions including; generating downlink control information (DCI) that indicates a future resource assignment for a user equipment (UE) on a physical downlink shared channel (PDSCH); and sending, to the UE at a static reserved resource block location or at a dynamic resource block location, the DCI in a PDSCH payload; wherein; inclusion of the DCI in the PDSCH payload allows the UE to refrain from decoding a physical downlink control channel (PDCCH) until after receipt of the DCI via the PDSCH. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A method for reducing power consumption by a user equipment (UE) communicating within a cellular wireless network, the method comprising:
-
by the UE, during a designated time interval; refraining from decoding a PDCCH until after receipt of downlink control information (DCI) in a physical downlink shared channel (PDSCH) payload received from a network apparatus of the cellular wireless network; receiving, from the network apparatus at a static resource block location or at a dynamic resource block location, the PDSCH payload including the DCI; decoding the PDSCH payload to obtain the DCI; and decoding the PDCCH based on the DCI. - View Dependent Claims (20)
