Abstract

Apparatuses, methods, and systems are disclosed for transmitting and/or receiving system information for changing a configuration. One apparatus includes a receiver that: receives first system information for a first configuration; and receives second system information for a second configuration based on the first configuration. The second system information includes changes to the first configuration without repeating information common to the first and second configurations.

Claims (53)

1 . A user equipment (UE), comprising:

at least one memory; and

at least one processor coupled with the at least one memory and configured to cause the UE to:

receive a configuration for requesting a set of system information blocks (SIBs) on-demand based in part on a random access procedure, wherein the configuration comprises an indicator configured to indicate each of whether the set of SIBs:

is broadcast regularly;

is only available on-demand;

uses a first configuration without using a second configuration; and

uses the first configuration with the second configuration;

transmit an on-demand request for a SIB associated with the set of SIBs based at least in part on the indicator;

receive the SIB based at least in part on the on-demand request;

store the SIB; and

discard the stored SIB based at least in part on a predetermined time.

2 . The UE of claim 1 , wherein, to discard the stored SIB, the at least one processor is configured to cause the UE to:

delete the stored SIB after the predetermined time,

wherein the predetermined time comprises three hours.

3 . The UE of claim 2 , wherein to discard the stored SIB is further based at least in part on a validity of the SIB.

4 . The UE of claim 1 , wherein a validity of the SIB is based at least in part on a geographic coverage area.

5 . The UE of claim 4 , wherein the validity of the SIB is further based at least in part on a portion of the geographic coverage area.

6 . The UE of claim 5 , wherein the SIB is specific for the portion of the geographic coverage area.

7 . The UE of claim 5 , wherein the portion of the geographic coverage area comprises one or more of a radio access network (RAN) area, a tracking area (TA), or a paging area (PA).

8 . The UE of claim 1 , wherein the indicator comprises a two-bit indication.

9 . A method performed by a user equipment (UE), the method comprising:

receiving a configuration for requesting a set of system information blocks (SIBs) on-demand based in part on a random access procedure, wherein the configuration comprises an indicator configured to indicate each of whether the set of SIBs:

is broadcast regularly;

is only available on-demand;

uses a first configuration without using a second configuration; and

uses the first configuration with the second configuration;

transmitting an on-demand request for a SIB associated with the set of SIBs based at least in part on the indicator;

receiving the SIB based at least in part on the on-demand request;

storing the SIB; and

discarding the stored SIB based at least in part on a predetermined time.

10 . The method of claim 9 , wherein discarding the stored SIB comprises:

deleting the stored SIB after the predetermined time,

wherein the predetermined time comprises three hours.

11 . The method of claim 10 , wherein discarding the stored SIB is further based at least in part on a validity of the SIB.

12 . The method of claim 9 , wherein a validity of the SIB is based at least in part on a geographic coverage area.

13 . The method of claim 12 , wherein the validity of the SIB is further based at least in part on a portion of the geographic coverage area.

14 . The method of claim 13 , wherein the SIB is specific for the portion of the geographic coverage area.

15 . The method of claim 13 , wherein the portion of the geographic coverage area comprises one or more of a radio access network (RAN) area, a tracking area (TA), or a paging area (PA).

16 . A base station, comprising:

at least one memory; and

at least one processor coupled with at least one memory and configured to cause the base station to:

transmit a configuration for requesting a set of system information blocks (SIBs) on-demand using a random access channel (RACH) procedure, wherein the configuration comprises an indicator configured to indicate each of whether the set of SIBs:

is broadcast regularly;

is only available on-demand;

uses a first configuration without using a second configuration; and

uses the first configuration with the second configuration;

receive an on-demand request for a SIB associated with the set of SIBs based at least in part on the indicator; and

transmit the SIB based at least in part on the on-demand request.

17 . The base station of claim 16 , wherein a validity of the SIB is based at least in part on a geographic coverage area.

18 . The base station of claim 17 , wherein the validity of the SIB is further based at least in part on a portion of the geographic coverage area.

19 . The base station of claim 18 , wherein the SIB is specific for the portion of the geographic coverage area.

20 . The base station of claim 18 , wherein the portion of the geographic coverage area comprises one or more of a radio access network (RAN) area, a tracking area (TA), or a paging area (PA).
