Control signaling optimization for LTE communications
Abstract:
The disclosure describes procedures for including downlink control information (DCI) within a physical downlink shared channel (PDSCH) communication to reduce power consumption for a user equipment (UE) operating in a Long Term Evolution (LTE) network. A network apparatus can be configured to identify an expected DCI change for the UE, determine whether an LTE subframe location for the DCI change is known, generate either a general or a specific DCI change indicator, and send the corresponding DCI change indicator to the UE on the PDSCH. The specific DCI change indicator can include a bitmap identifying a particular upcoming LTE subframe where the UE is required to decode the PDCCH for DCI, and the general DCI change indicator can include a bit flag identifying a time associated with one or more upcoming LTE subframes when the UE should decode the PDCCH for DCI.
