Abstract

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may release a connection with a first network entity and determine a first virtual coverage area of the UE based on a geographic location of the UE associated with the release of the connection. The UE may obtain a message that includes area information. The area information may be indicative of one or more second virtual coverage areas, which the UE may use in determining whether to monitor for a paging early indication (PEI). Based on the first virtual coverage area and the one or more second virtual coverage areas may monitor for a paging message, such as the PEI or downlink control information (DCI) associated with a paging occasion.

First claim

What is claimed is:

1 . An apparatus for wireless communication at a user equipment (UE), comprising:
one or more memories; and one or more processors coupled with the one or more memories and configured to cause the UE to:
communicate a connection release message to release a first connection between the UE and a network entity, wherein a geographic location of the UE associated with the release of the first connection corresponds to a first virtual coverage area associated with a geographic coverage area;
obtain area information comprising an indication of one or more second virtual coverage areas that are associated with a paging early indication for one or more paging occasions associated with the one or more second virtual coverage areas; and
monitor for the paging early indication based at least in part on the first virtual coverage area of the UE that is included in the one or more second virtual coverage areas.

2 . The apparatus of claim 1 , wherein the area information comprises an indication to monitor for the paging early indication based at least in part on a current virtual coverage area of the UE, and wherein, to monitor for the paging early indication, the one or more processors are configured to cause the UE to:
monitor for the paging early indication based at least in part on the first virtual coverage area that is the same as the one or more second virtual coverage areas, wherein the one or more second virtual coverage areas correspond to a current geographic location of the UE.

3 . The apparatus of claim 1 , wherein the area information comprises an indication to monitor for the paging early indication based at least in part on a current virtual coverage area of the UE, and wherein, to monitor for the paging early indication, the one or more processors are configured to cause the UE to:
monitor for downlink control information associated with a paging occasion based at least in part on the first virtual coverage area that is different than the one or more second virtual coverage areas, wherein the one or more second virtual coverage areas correspond to a current geographic location of the UE.

4 . The apparatus of claim 1 , wherein the area information comprises a last-used-virtual-coverage-area-only indication associated with the paging early indication, and wherein, to monitor for the paging early indication, the one or more processors are configured to cause the UE to:
monitor for downlink control information associated with a paging occasion based at least in part on the last-used-virtual-coverage-area-only indication and whether the first virtual coverage area is the same as the one or more second virtual coverage areas, wherein the one or more second virtual coverage areas correspond to a current geographic location of the UE.

5 . The apparatus of claim 1 , wherein, to monitor for the paging early indication, the one or more processors are configured to cause the UE to:
monitor for or downlink control information associated with a paging occasion based at least in part on whether a first index of the first virtual coverage area corresponds to a second index associated with the one or more second virtual coverage areas.

6 . The apparatus of claim 1 , wherein at least one of the first virtual coverage area of the UE and the one or more second virtual coverage areas is determined via use of a function that maps geographic locations to the at least one of the first virtual coverage area of the UE and the one or more second virtual coverage areas.

7 . The apparatus of claim 6 , further comprising:
one or more antennas, wherein the one or more antennas and the one or more processors are configured to cause the UE to:
obtain a control message that indicates the function.

8 . The apparatus of claim 1 , wherein the one or more processors are configured to cause the UE to:
establish a second connection for the UE, wherein the area information is obtained based at least in part on the establishment of the second connection.

9 . The apparatus of claim 1 , wherein:
the first virtual coverage area is a first virtual cell or a first virtual beam; and the one or more second virtual coverage areas are one or more second virtual cells or one or more second virtual beams.

10 . The apparatus of claim 1 , wherein, to monitor for the paging early indication, the one or more processors are configured to cause the UE to:
monitor for a wake-up signal based at least in part on the first virtual coverage area that is included in the one or more second virtual coverage areas.

11 . The apparatus of claim 1 , wherein the area information is included in a broadcast message.

12 . The apparatus of claim 1 , wherein the area information is included in a multicast message.

13 . An apparatus for wireless communication at a network entity, comprising:
one or more memories; and one or more processors coupled with the one or more memories and configured to cause the network entity to:
communicate a connection release message to release a first connection for communication between the network entity and a first user equipment (UE), wherein a first virtual coverage area associated with the release of the first connection corresponds to a geographic coverage area;
output area information comprising an indication of one or more second virtual coverage areas that are associated with a paging early indication; and
output the paging early indication to one or more UEs based at least in part on a respective virtual coverage area of each of the one or more UEs that is included in the one or more second virtual coverage areas.

14 . The apparatus of claim 13 ,
wherein the one or more UEs include the first UE or exclude the first UE based at least in part on whether the first virtual coverage area is included in the one or more second virtual coverage areas.

15 . The apparatus of claim 13 , wherein the area information comprises an indication to monitor for the paging early indication based at least in part on a current virtual coverage area, and wherein, to output the paging early indication, the one or more processors are configured to cause the network entity to:
output the paging early indication based at least in part on the respective virtual coverage area of each of the one or more UEs that is the same as the one or more second virtual coverage areas.

16 . The apparatus of claim 13 , wherein the area information comprises an indication to monitor for the paging early indication based at least in part on a current virtual coverage area, and wherein, to output the paging early indication, the one or more processors are configured to cause the network entity to:
output downlink control information associated with a paging occasion based at least in part on the respective virtual coverage area of each of the one or more UEs that is different than the one or more second virtual coverage areas.

17 . The apparatus of claim 13 , wherein the area information comprises a last-used-virtual-coverage-area-only indication associated with the paging early indication, and wherein, to output the paging early indication, the one or more processors are configured to cause the network entity to:
output downlink control information associated with a paging occasion based at least in part on the last-used-virtual-coverage-area-only indication and whether the respective virtual coverage area of each of the one or more UEs is the same as the one or more second virtual coverage areas.

18 . The apparatus of claim 13 , wherein, to o
