Abstract

Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may perform a first cell search operation to initiate selection of a first cell associated with a network entity. The first UE may obtain cell selection information that facilitates performance, by one or more second UEs, of a second cell search operation based on performing the first cell search operation. The first UE and the one or more second UEs may be located within a threshold distance of each other. The second cell search operation may initiate selection of the first cell and may be simplified with respect to the first cell search operation. The first UE may transmit the cell selection information to the one or more second UEs of the set of UEs. The first UE and the one or more second UEs may establish respective connections with the network entity.

First claim

What is claimed is:

1 . A first user equipment (UE), comprising:
one or more memories storing processor-executable code; and one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the first UE to:
perform a first cell search operation to initiate selection of a first cell associated with a network entity;
obtain cell measurement-related information that facilitates performance, by one or more second UEs of a set of UEs, of a second cell search operation to initiate selection of the first cell based at least in part on performing the first cell search operation, wherein the second cell search operation is simplified with respect to the first cell search operation; and
transmit the cell measurement-related information to the one or more second UEs of the set of UEs based at least in part on obtaining the cell measurement-related information, wherein the first UE and the one or more second UEs are included in the set of UEs based at least in part on the first UE and the one or more second UEs being within a threshold distance of each other.

2 . The first UE of claim 1 , wherein the cell measurement-related information includes cell measurement configuration information, cell measurement result information, or both.

3 . The first UE of claim 1 , wherein the one or more processors are individually or collectively further operable to execute the code to cause the first UE to:
obtain system information that facilitates the performance of the second cell search operation; and transmit the system information to the one or more second UEs of the set of UEs based at least in part on obtaining the system information.

4 . The first UE of claim 3 , wherein, to obtain the system information, the one or more processors are individually or collectively operable to execute the code to cause the first UE to:
obtain the system information during a connection establishment operation with the network entity or based at least in part on a network configuration change at the network entity.

5 . The first UE of claim 3 , wherein the one or more processors are individually or collectively further operable to execute the code to cause the first UE to:
receive, from a second UE of the one or more second UEs, a request for the system information, wherein transmitting the system information is based at least in part on receiving the request.

6 . The first UE of claim 3 , wherein the one or more processors are individually or collectively further operable to execute the code to cause the first UE to:
transmit, to the network entity, a request for the system information, wherein obtaining the system information is based at least in part on transmitting the request.

7 . The first UE of claim 1 , wherein, to obtain the cell measurement-related information, the one or more processors are individually or collectively operable to execute the code to cause the first UE to:
receive one or more synchronization signals from the network entity based at least in part on performing the first cell search operation; and decode a reference signal based at least in part on receiving the one or more synchronization signals, wherein the transmitted cell measurement-related information includes first information associated with the one or more synchronization signals, second information associated with the reference signal, or both.

8 . The first UE of claim 7 , wherein the one or more processors are individually or collectively further operable to execute the code to cause the first UE to:
establish a connection with the network entity in accordance with the first information, the second information, or both, wherein transmitting the cell measurement-related information is based at least in part on establishing the connection.

9 . The first UE of claim 1 , wherein, to obtain the cell measurement-related information, the one or more processors are individually or collectively operable to execute the code to cause the first UE to:
receive one or more system information blocks (SIBs) associated with the first cell that include first information associated with one or more second cells different than the first cell, the transmitted cell measurement-related information including the first information.

10 . The first UE of claim 9 , wherein the first information includes cell remeasurement-related information that includes priority information associated with the one or more second cells, one or more threshold values associated with the one or more second cells, one or more offsets associated with the one or more second cells, frequency information, one or more measurement configurations associated with the one or more second cells, or any combination thereof.

11 . The first UE of claim 9 , wherein the one or more processors are individually or collectively further operable to execute the code to cause the first UE to:
select a second cell of the one or more second cells, wherein transmitting the cell measurement-related information is based at least in part on selecting the second cell.

12 . The first UE of claim 9 , wherein the transmitted cell measurement-related information further includes second information associated with the one or more second cells, the second information indicative of a search window for synchronization signal blocks (SSBs), a list of second cells that are detectable by the first UE, a power change of a second cell, a list of second cells that are not to be considered for cell reselection, or any combination thereof.

13 . The first UE of claim 1 , wherein, to transmit the cell measurement-related information, the one or more processors are individually or collectively operable to execute the code to cause the first UE to:
transmit the cell measurement-related information via a broadcast channel, a sidelink channel, a wireless local-area network (WLAN), a Bluetooth link, or any combination thereof.

14 . The first UE of claim 1 , wherein the threshold distance is associated with a set of one or more beams of the network entity, the first UE and the one or more second UEs being located within the set of one or more beams.

15 . The first UE of claim 1 , wherein the threshold distance is associated with a set of one or more cells of the network entity, the first UE and the one or more second UEs being located within the set of one or more cells of the network entity.

16 . The first UE of claim 1 , wherein at least one of the first UE or the one or more second UEs are in a radio resource control (RRC) inactive mode.

17 . The first UE of claim 1 , wherein the one or more processors are individually or collectively further operable to execute the code to cause the first UE to:
determine to transmit the cell measurement-related information based at least in part on a battery level of the first UE, a connection state of the first UE, a capability of the first UE, or any combination thereof.

18 . The first UE of claim 1 , wherein transmitting the cell measurement-related information to the one or more second UEs is based at least in part on the first UE satisfying a policy defined by the network entity.

19 . The first UE of claim 1 , wherein the one or more processors are individually or collectively further operable to execute the code to cause the first UE to:
