Common channel configuration in new radio inactive state
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a radio resource control (RRC) resume message, associated with transitioning the UE from an inactive state to a connected state. The UE may configure, based at least in part on receiving the RRC resume message, the UE with a serving cell common configuration, associated with a serving cell of the UE, received in a system information block (SIB) associated with the serving cell. Numerous other aspects are provided.
1. A method of wireless communication performed by a user equipment (UE), comprising:
obtaining an access stratum (AS) context comprising a first serving cell common configuration associated with a first cell while the UE is in a connected state;
receiving a system information block (SIB) associated with a second cell in connection with the UE switching to the second cell,
the SIB including a second serving cell common configuration for the second cell;
receiving a radio resource control (RRC) resume message, associated with transitioning the UE from an inactive state to the connected state, separately from receiving the SIB; and
configuring, based at least in part on receiving the RRC resume message, the UE with the second serving cell common configuration received in the SIB.
2. The method of claim 1 , wherein, when the RRC resume message includes a third serving cell common configuration, the UE is further configured with the third serving cell common configuration included in the RRC resume message,
wherein the third serving cell common configuration included in the RRC resume message overwrites the second serving cell common configuration received in the SIB.
3. The method of claim 1 , wherein the RRC resume message does not include a serving cell common configuration.
4. The method of claim 1 , wherein the UE is further configured based at least in part on the AS context obtained by the UE before entering the inactive state.
5. The method of claim 1 , wherein the UE is configured with the second serving cell common configuration received in the SIB instead of using the first serving cell common configuration obtained from the first cell.
6. The method of claim 1 , wherein the SIB, associated with the second cell, is received based at least in part on UE mobility that causes the UE to reselect to the second cell.
7. The method of claim 1 , wherein the SIB, associated with the second cell, is SIB1 associated with the second cell.
8. The method of claim 1 , wherein the RRC resume message is received in connection with a RRC resume request being sent by the UE,
wherein the RRC resume request is sent by the UE based at least in part on detection of a trigger to transition the UE from the inactive state to the connected state.
9. The method of claim 1 , wherein the UE transitions to the connected state from the inactive state after configuration of the UE with the second serving cell common configuration received in the SIB.
10. A user equipment (UE) for wireless communication, comprising:
a memory; and
one or more processors coupled to the memory, the memory and the one or more processors configured to:
obtain an access stratum (AS) context comprising a first serving cell common configuration associated with a first cell while the UE is in a connected state;
receive a system information block (SIB) associated with a second cell in connection with the UE switching to the second cell,
the SIB including a second serving cell common configuration for the second cell;
receive a radio resource control (RRC) resume message, associated with transitioning the UE from an inactive state to the connected state, separately from receiving the SIB; and
configure, based at least in part on receiving the RRC resume message, the UE with the second serving cell common configuration received in the SIB.
11. The UE of claim 10 , wherein, when the RRC resume message includes a third serving cell common configuration, the UE is further configured with the third serving cell common configuration included in the RRC resume message,
wherein the third serving cell common configuration included in the RRC resume message overwrites the second serving cell common configuration received in the SIB.
12. The UE of claim 10 , wherein the RRC resume message does not include a serving cell common configuration.
13. The UE of claim 10 , wherein the UE is further configured based at least in part on the AS context obtained by the UE before entering the inactive state.
14. The UE of claim 10 , wherein the UE is configured with the second serving cell common configuration received in the SIB instead of using the first serving cell common configuration obtained from the first cell.
15. The UE of claim 10 , wherein the SIB, associated with the second cell, is received based at least in part on UE mobility that causes the UE to reselect to the second cell.
16. The UE of claim 10 , wherein the SIB, associated with the second cell, is SIB1 associated with the second cell.
17. The UE of claim 10 , wherein the RRC resume message is received in connection with a RRC resume request being sent by the UE,
wherein the RRC resume request is sent by the UE based at least in part on detection of a trigger to transition the UE from the inactive state to the connected state.
18. The UE of claim 10 , wherein the UE transitions to the connected state from the inactive state after configuration of the UE with the second serving cell common configuration received in the SIB.
19. A non-transitory computer-readable medium storing one or more instructions for wireless communication, the one or more instructions comprising:
one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the one or more processors to:
obtain an access stratum (AS) context comprising a first serving cell common configuration associated with a first cell while the UE is in a connected state;
receive a system information block (SIB) associated with a second cell in connection with the UE switching to the second cell,
the SIB including a second serving cell common configuration for the second cell;
receive a radio resource control (RRC) resume message, associated with transitioning the UE from an inactive state to the connected state, separately from receiving the SIB; and
configure, based at least in part on receiving the RRC resume message, the UE with the second serving cell common configuration received in the SIB.
20. The non-transitory computer-readable medium of claim 19 , wherein, when the RRC resume message includes a third serving cell common configuration, the UE is further configured with the third serving cell common configuration included in the RRC resume message,
wherein the third serving cell common configuration included in the RRC resume message overwrites the second serving cell common configuration received in the SIB.
21. The non-transitory computer-readable medium of claim 19 , wherein the RRC resume message does not include a serving cell common configuration.
22. The non-transitory computer-readable medium of claim 19 , wherein the UE is further configured based at least in part on the AS context obtained by the UE before entering the inactive state.
