Methods and apparatus for paging reception in wireless communication
An approach to communication by a user equipment (UE) in a wireless communication system that includes the UE sending an RRC setup request message including a paging offset value to a base station. The UE receives an RRC setup message from the network node, the RRC setup message including a PS-paging offset value and a PS-P-RNTI value associated with the UE. Energy conservation approaches for use with paging are described, including paging occasion monitor reporting and configuration, paging-offset reporting, the use of a paging monitoring skipping signal, and the use of dynamic TRS triggering for paging reception.
1. A method for communication by a user equipment (UE) in a wireless communication system, the method comprising:
sending a radio resource control (RRC) setup request message including a paging offset value to a network node; and
receiving an RRC setup message from the network node, the RRC setup message including a PS-paging offset value and a PS-Paging-Radio Network Temporary Identifier (PS-P-RNTI) value associated with the UE.
2. The method of claim 1 , wherein the RRC setup message further includes a search space configuration indication.
3. The method of claim 2 , further comprising:
entering a micro-sleep phase based on the search space configuration indication.
4. The method of claim 1 , further comprising:
receiving Downlink Control Information (DCI) information in a block associated with the UE, the DCI information having a paging occasion (PO) indicator field, an aperiodic Channel State Information-Reference Signal (CSI-RS) field, and a skipped Discontinuous Reception (DRX) cycle indicator field.
5. The method of claim 4 , wherein a starting position of the block is provided by a higher layer configuration of the UE.
6. The method of claim 4 , wherein the DCI information further includes a field indicative of a triggered Tracking Reference Signal (TRS) timing parameter.
7. The method of claim 1 , wherein the paging offset value is based on a number of Synchronization Signal Blocks (SSB) needed by the UE to maintain synchronization.
8. A user equipment (UE) for communicating with a network node in a wireless communication system, the UE comprising:
a transceiver configured to transmit data to the network node, and to receive data from the network node; and
processor circuitry configured to:
send, using the transceiver, a radio resource control (RRC) setup request message including a paging offset value to the network node; and
receive, using the transceiver, an RRC setup message from the network node, the RRC setup message including a PS-paging offset value and a PS-Paging-Radio Network Temporary Identifier (PS-P-RNTI) value associated with the UE.

12. The UE of claim 11 , wherein a starting position of the block is provided by a higher layer configuration of the UE.
13. The UE of claim 11 , wherein the DCI information further includes a field indicative of a triggered Tracking Reference Signal (TRS) timing parameter.
14. The UE of claim 8 , wherein the paging offset value is based on a number of Synchronization Signal Blocks (SSB) needed by the UE to maintain synchronization.
15. A network node for communicating with a user equipment (UE) in a wireless communication system, the network node comprising:
a transceiver configured to transmit data to the UE, and to receive data from the UE; and
processor circuitry configured to:
receive, via the transceiver, a radio resource control (RRC) setup request message including a paging offset value from the UE; and
send, via the transceiver, an RRC setup message to the UE, the RRC setup message including a PS-paging offset value and a PS-Paging-Radio Network Temporary Identifier (PS-P-RNTI) value associated with the UE.
16. The network node of claim 15 , wherein the RRC setup message further includes a search space configuration indication.
17. The network node of claim 15 , wherein the processor circuitry is further configured to:
transmit Downlink Control Information (DCI) information in a block associated with the UE, the DCI information having a paging occasion (PO) indicator field, an aperiodic Channel State Information-Reference Signal (CSI-RS) field, and a skipped Discontinuous Reception (DRX) cycle indicator field.
18. The network node of claim 17 , wherein a starting position of the block is provided by a higher layer configuration of the UE.
