Threshold-based system information on demand
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit a request for system information based at least in part on a threshold; and receive the system information based at least in part on the request. A base station may receive a request for system information, wherein the request is based at least in part on a threshold; and transmit the system information to a user equipment (UE) associated with the request based at least in part on the request. Numerous other aspects are provided.
1. A method of wireless communication performed by a user equipment (UE), comprising:
transmitting a request for cell reselection-related system information based at least in part on a measurement performed by the UE satisfying a first threshold associated with requesting the cell reselection-related system information,
wherein the first threshold is different than a second threshold for performing cell reselection; and
receiving the cell reselection-related system information based at least in part on the request.
2. The method of claim 1 , further comprising:
performing the measurement, wherein transmitting the request is based at least in part on comparing result of the measurement with the first threshold.
3. The method of claim 2 , wherein the measurement is based at least in part on at least one of a reference signal received power, a reference signal received quality, or a signal to interference plus noise ratio.
4. The method of claim 1 , wherein the first threshold is associated with a reporting event.
5. The method of claim 1 , further comprising:
receiving information from a base station identifying the first threshold, wherein the request is transmitted to the base station.
6. The method of claim 1 , wherein the first threshold is for a serving cell of the UE.
7. The method of claim 1 , further comprising:
determining the first threshold based on at least one of:
a preconfigured value,
a condition or parameter of the UE, or
a mobility state of the UE.
8. The method of claim 1 , further comprising:
determining that the first threshold is satisfied.
9. The method of claim 1 , wherein the request comprises a random access message or a connection request message.
10. The method of claim 1 , wherein the request is transmitted based at least in part on initiating a random access procedure.
11. A method of wireless communication performed by a base station, comprising:
receiving a request for cell reselection-related system information, wherein the request is based at least in part on a measurement performed by a user equipment (UE) satisfying a first threshold associated with requesting the cell reselection-related system information,
wherein the first threshold is determined or configured by the base station, and
wherein the first threshold is different than a second threshold for performing cell reselection; and
transmitting the cell reselection-related system information to the UE based at least in part on the request.
12. The method of claim 11 , wherein transmitting the cell reselection-related system information further comprises broadcasting or unicasting the cell reselection-related system information.
13. The method of claim 11 , wherein the first threshold is associated with a reporting event.
14. The method of claim 11 , further comprising:
transmitting, broadcasting, or unicasting information identifying the first threshold.
15. The method of claim 11 , wherein the base station provides a serving cell of the UE.
16. The method of claim 11 , wherein the request comprises a random access message.
17. The method of claim 11 , wherein the request is transmitted based at least in part on initiating a random access procedure.
18. The method of claim 11 , wherein the cell reselection-related system information is selected for the UE based at least in part on a content of the request.
19. A user equipment (UE) for wireless communication, comprising:
a memory; and
one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
transmit a request for cell reselection-related system information based at least in part on a measurement performed by the UE satisfying a first threshold associated with requesting the cell reselection-related system information,
wherein the first threshold is different than a second threshold for performing cell reselection; and
receive the cell reselection-related system information based at least in part on the request.
20. The UE of claim 19 , wherein the one or more processors are further to:
perform the measurement, wherein transmitting the request is based at least in part on comparing result of the measurement with the first threshold.
21. The UE of claim 19 , wherein the one or more processors are further configured to:
receive information from a base station identifying the first threshold, wherein the request is transmitted to the base station.
22. The UE of claim 19 , wherein the one or more processors are further configured to:
determine the first threshold based on at least one of:
a preconfigured value,
a condition or parameter of the UE, or
a mobility state of the UE.
23. The UE of claim 19 , wherein the measurement is based at least in part on at least one of a reference signal received power, a reference signal received quality, or a signal to interference plus noise ratio.
24. The UE of claim 19 , wherein the first threshold is for a serving cell of the UE.
25. The UE of claim 19 , wherein the one or more processors are further to:
determine that the first threshold is satisfied.
26. A base station for wireless communication, comprising:
a memory; and
one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
receive a request for cell reselection-related system information, wherein the request is based at least in part on a measurement performed by a user equipment (UE) satisfying a first threshold,
wherein the first threshold is determined or configured by the base station, and
wherein the first threshold is different than a second threshold for performing cell reselection; and
transmit the cell reselection-related system information to the UE based at least in part on the request.
27. The base station of claim 26 , wherein the one or more processors are further configured to:
transmit or broadcast information identifying the first threshold.
28. The base station of claim 26 , wherein the base station provides a serving cell of the UE.
