Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may communicate in a network based at least in part on using a first connection configuration. The UE may communicate in the network based at least in part using a second connection configuration instead of the first connection configuration. The UE may autonomously switch to reusing the first connection configuration for communicating in the network based at least in part on the first connection configuration being stored at the UE. Numerous other aspects are described.

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 to the one or more memories, configured to:
communicate in a network based at least in part on using a first connection configuration that is based at least in part on a first beam configuration;
communicate in the network based at least in part using a second connection configuration instead of the first connection configuration, wherein the second connection configuration is based at least in part on a second beam configuration;
detect, as a switch event, that a satellite location associated with a target network node satisfies a satellite location condition associated with the first connection configuration; and
autonomously switch from using the second connection configuration stored locally at the UE to reusing the first connection configuration stored locally at the UE for communicating with the target network node in the network based at least in part on the first connection configuration being stored at the UE and based at least in part on detection of the switch event.

2 . The apparatus of claim 1 , wherein the one or more processors, to detect the switch event, are configured to:
detect receipt of a configuration identifier associated with the first connection configuration, detect receipt of a handover command, detect that a signal metric satisfies a switch condition, detect that current satellite ephemeris is commensurate with satellite ephemeris associated with the first connection configuration, detect that a current elevation angle associated with communicating with a satellite is commensurate with an elevation angle associated with the first connection configuration, detect that a current UE location satisfies a UE location condition, detect that a current time occurs within a configured time duration, or detect that a current connection identifier is associated with the first connection configuration.

3 . The apparatus of claim 1 , wherein the one or more processors are further configured to:
transmit a switch indication that is associated with autonomously switching to the first connection configuration.

4 . The apparatus of claim 3 , wherein the switch indication specifies a configuration identifier associated with the first connection configuration.

5 . The apparatus of claim 3 , wherein the one or more processors, to transmit the switch indication, are configured to:
transmit the switch indication in at least one of:
uplink control information,
a medium access control (MAC) control element (CE), or
a radio resource control (RRC) message.

6 . The apparatus of claim 1 , wherein the one or more processors are further configured to:
store the first connection configuration at the UE.

7 . The apparatus of claim 1 , wherein the network comprises a non-terrestrial network.

8 . The apparatus of claim 1 , wherein the one or more processors are further configured to:
receive the first connection configuration or the second connection configuration based at least in part on at least one of:
a broadcast message,
a unicast message, or
a multicast message.

9 . The apparatus of claim 1 , wherein the one or more processors are further configured to:
communicate, based at least in part on autonomously switching to the first connection configuration, in the network based at least in part on using the first connection configuration.

10 . The apparatus of claim 1 , wherein the one or more processors are further configured to:
receive the first connection configuration from a first network node in the network, communicate with the first network node in the network based at least in part on the first connection configuration, and communicate with a second network node in the network based at least in part on the first connection configuration being stored at the UE.

11 . The apparatus of claim 1 , wherein the one or more processors are further configured to:
receive an update indication to update at least one of:
the first connection configuration, or
the second connection configuration, and
update at least one of the first connection configuration or the second connection configuration based at least in part on the update indication.

12 . The apparatus of claim 1 , wherein the one or more processors are further configured to:
receive, prior to communicating using the second connection configuration and autonomously switching to the first connection configuration, a configuration indication that specifies a set of connection configurations that comprises at least one of:
the first connection configuration, or
the second connection configuration.

13 . The apparatus of claim 12 , wherein the one or more processors, to receive the configuration indication, are configured to:
receive the configuration indication in at least one of:
a broadcast message, or
a multicast message.

14 . The apparatus of claim 12 , wherein the one or more processors, to receive the configuration indication, are configured to:
receive the configuration indication in a system information block.

15 . An apparatus for wireless communication at a network node, comprising:
one or more memories; and one or more processors, coupled to the one or more memories, configured to:
transmit at least one of a first connection configuration that is based on a first beam configuration or a second connection configuration that is based on a second beam configuration;
communicate with a user equipment (UE) in a network based at least in part on using the first connection configuration;
communicate with the UE in the network based at least in part on using the second connection configuration; and
communicate with the UE in the network based at least in part on a switch from using the second connection configuration to reusing the first connection configuration and without an additional transmission of the first connection configuration, wherein the switch is based at least in part on a satellite location associated with the network node satisfying a satellite location condition associated with the first connection configuration.

16 . The apparatus of claim 15 , wherein the one or more processors are further configured to:
receive a switch indication that indicates the UE is using the first connection configuration, wherein communicating with the UE in the network based at least in part on reusing the first connection configuration is based at least in part on receiving the switch indication.

17 . The apparatus of claim 16 , wherein the one or more processors, to receive the switch indication, are configured to:
receive the switch indication in at least one of:
uplink control information,
a medium access control (MAC) control element (CE), or
a radio resource control (RRC) message.

18 . The apparatus of claim 15 , wherein the one or more processors are further configured to:
transmit an additional connection configuration parameter that is additional to at least one of the second connection configuration or the first connection configuration.

19 . The apparatus of claim 15 , wherein the one or more processors, to transmit at least one of the first connection configuration or the second connection configuration, are configured to:
transmit a configuration indication that specifies a set of connection configurations that comprises at least one of:
the second connection configuration, or
the firs
