Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine updated system information for a user equipment (UE), wherein the UE is associated with an initial access bandwidth part (BWP) and a configured BWP; and transmit the updated system information to the UE using at least one of unicast signaling, multicast signaling, the configured BWP, or a particular BWP that is different from the configured BWP. Numerous other aspects are provided.

First claim

What is claimed is:

1. A method of wireless communication performed by a network entity, comprising:
determining updated system information for a user equipment (UE),
wherein the UE is associated with an initial access bandwidth part (BWP) and a configured BWP; and

transmitting the updated system information to the UE using at least one of the configured BWP or a particular BWP that is different from the initial access BWP.

2. The method of claim 1 ,
wherein the updated system information is transmitted further using unicast signaling, and
wherein the unicast signaling uses at least one of downlink control information, a media access control (MAC) control element (CE), or radio resource control (RRC) signaling.

3. The method of claim 1 ,
wherein the updated system information is transmitted further using multicast signaling, and
wherein the multicast signaling uses at least one of downlink control information, a media access control (MAC) control element (CE), or radio resource control (RRC) signaling.

4. The method of claim 1 ,
wherein the updated system information is transmitted further using multicast signaling, and
wherein the multicast signaling uses a group downlink control information associated with a particular group radio network temporary identifier (RNTI).

5. The method of claim 1 , further comprising:
transmitting a message to configure the UE to switch to or monitor the particular BWP,
wherein the updated system information is transmitted using at least the particular BWP.

6. The method of claim 5 , wherein the message is used to configure the UE to switch to or monitor the particular BWP for a particular length of time, and wherein the message is used to configure the UE to switch back to the configured BWP after the particular length of time.

7. The method of claim 5 , wherein the message is a paging message.

8. The method of claim 1 , wherein the updated system information is repeated in the configured BWP using a same periodicity as system information that is transmitted in the initial access BWP.

9. The method of claim 1 , wherein the updated system information is repeated in the configured BWP in a particular time window.

10. A network entity for wireless communication, comprising:
a memory; and
one or more processors operatively coupled to the memory, the one or more processors configured to:
determine updated system information for a user equipment (UE),
wherein the UE is associated with an initial access bandwidth part (BWP) and a configured BWP; and

transmit the updated system information to the UE using at least one of the configured BWP or a particular BWP that is different from the initial access BWP.

11. The network entity of claim 10 ,
wherein the updated system information is transmitted further using unicast signaling, and
wherein the unicast signaling uses at least one of downlink control information, a media access control (MAC) control element (CE), or radio resource control (RRC) signaling.

12. The network entity of claim 10 ,
wherein the updated system information is transmitted further using multicast signaling, and wherein the multicast signaling uses at least one of downlink control information, a media access control (MAC) control element (CE), or radio resource control (RRC) signaling.

13. The network entity of claim 10 ,
wherein the updated system information is transmitted further using multicast signaling, and wherein the multicast signaling uses a group downlink control information associated with a particular group radio network temporary identifier (RNTI).

14. The network entity of claim 10 ,
wherein the one or more processors are further configured to:
transmit a message to configure the UE to switch to or monitor the particular BWP, and

wherein the updated system information is transmitted using at least the particular BWP.

15. The network entity of claim 14 , wherein the message is used to configure the UE to switch to or monitor the particular BWP for a particular length of time, and
wherein the message is used to configure the UE to switch back to the configured BWP after the particular length of time.

16. The network entity of claim 14 , wherein the message is a paging message.

17. The network entity of claim 10 , wherein the updated system information is repeated in the configured BWP using a same periodicity as system information that is transmitted in the initial access BWP.

18. The network entity of claim 10 , wherein the updated system information is repeated in the configured BWP in a particular time window.

19. A method of wireless communication performed by a user equipment (UE), comprising:
receiving updated system information for the UE,
wherein the UE is associated with an initial access bandwidth part (BWP) and a configured BWP, and
wherein the updated system information is received using at least one of the configured BWP or a particular BWP that is different from the initial access BWP; and

processing the updated system information.

20. The method of claim 19 ,
wherein the updated system information is received further using unicast signaling, and
wherein the unicast signaling includes at least one of downlink control information, a media access control (MAC) control element (CE), or radio resource control (RRC) signaling.

21. The method of claim 19 , further comprising:
switching to or monitoring the particular BWP based at least in part on a received message,
wherein the updated system information is received using at least the particular BWP.

22. A user equipment (UE) for wireless communication, comprising:
a memory; and
one or more processors operatively coupled to the memory, the one or more processors configured to:
receive updated system information for the UE,
wherein the UE is associated with an initial access bandwidth part (BWP) and a configured BWP, and
wherein the updated system information is received using at least the configured BWP or a particular BWP that is different from the initial access BWP; and

process the updated system information.

23. The UE of claim 22 ,
wherein the updated system information is received further using unicast signaling, and
wherein the unicast signaling includes at least one of downlink control information, a media access control (MAC) control element (CE), or radio resource control (RRC) signaling.

24. The UE of claim 22 ,
wherein the one or more processors are configured to:
switch to or monitor the particular BWP based at least in part on a received message, and

wherein the updated system information is received using at least the particular BWP.

25. The UE of claim 22 , wherein the updated system information is received using at least the configured BWP.

26. The UE of claim 22 , wherein the updated system information is received using at least the particular BWP.

27. The network entity of claim 10 , wherein the updated system information is transmitted using at least the configured BWP.

28. The network entity of claim 10 , wherein the updated system information is received using at least the particular BWP.
