Abstract
Certain aspects of the present disclosure relate to wireless communications, and more particularly, techniques for an enhanced paging procedure. A method that may be performed by a user equipment (UE) includes detecting, during a paging occasion (PO), at least one downlink control information (DCI) that indicates a paging message and additional downlink signals and using the additional downlink signals to enhance processing of the paging message.
Claims29
A method for wireless communications by a user equipment (UE), comprising:
- detecting, during a paging occasion (PO), at least one downlink control information (DCI) that indicates a paging message and additional downlink signals, wherein the additional downlink signals comprise aperiodic tracking reference signals (A-TRSs);
- and
- using the additional downlink signals to enhance processing of the paging message, comprising performing channel tracking based on the A-TRSs before processing the paging message.
A method for wireless communications by a user equipment (UE), comprising:
- detecting, during a paging occasion (PO), at least one downlink control information (DCI) that indicates a paging message and additional downlink signals, wherein the additional downlink signals comprise at least one repetition of a physical downlink control channel (PDCCH) carrying the paging DCI or a repetition of the paging message;
- and
- using the additional downlink signals to enhance processing of the paging message, comprising at least one of using the repetition of the PDCCH or paging message for timing synchronization or combining.
A method for wireless communications by a network entity, comprising:
- transmitting to a user equipment (UE), during a paging occasion (PO), a paging downlink control information (DCI) that indicates a paging message and additional downlink signals;
- transmitting the paging message;
- and
- transmitting the additional downlink signals in accordance with the indication, wherein:
- the additional downlink signals comprise aperiodic tracking reference signals (A-TRSs),
- the A-TRSs are located in a same slot as the paging message, and
- the network entity performs rate matching for the paging message around the A-TRSs.
