Abstract
A user equipment (UE) performs a method of obtaining system information. The method includes disabling (328) a system information request function of the UE while the UE is in an inactive state and, while the system information request function is disabled and the UE is in the inactive state, communicating (316) with a radio access network (RAN) using small data transmission (SDT). The method also includes enabling (330) the system information request function of the UE when the UE is no longer communicating with the RAN using SDT.
Claims18
A method, performed by a user equipment (UE), of obtaining system information, the method comprising:
- disabling a system information request function of the UE while the UE is in an inactive state;
- while the system information request function is disabled and the UE is in the inactive state, communicating with a radio access network (RAN) using small data transmission (SDT);
- initiating, during the communicating, a system information request;
- and
- in response to initiating the system information request, (i) stopping SDT with the RAN and (ii) requesting system information from the RAN, wherein requesting the system information from the RAN includes enabling the system information request function of the UE when the UE is no longer communicating with the RAN using SDT.
(canceled)
A user equipment (UE) comprising processing hardware and configured to:
- disable a system information request function of the UE while the UE is in an inactive state;
- while the system information request function is disabled and the UE is in the inactive state, communicate with a radio access network (RAN) using small data transmission (SDT);
- initiate, during the communicating, a system information request;
- and
- in response to initiating the system information request, (i) stop SDT with the RAN and (ii) request system information from the RAN, wherein requesting the system information from the RAN includes enabling the system information request function of the UE when the UE is no longer communicating with the RAN using SDT.
