## Abstract

A method of system information transmissions performed by a user equipment (UE) includes receiving a system information (SI) scheduling information list for a plurality of SI messages and a random access resource list for a plurality of SI requests via a system information block type 1 (SIB1), and determining, when a plurality of random access resource entries exist in the random access resource list for the plurality of SI requests including a first SI request and a second SI request, that a first entry of the plurality of random access resource entries in the random access resource list for the first SI request corresponds to a first entry in the SI scheduling information list and that a second entry of the plurality of random access resource entries in the random access resource list for the second SI request corresponds to a second entry in the SI scheduling information list.

## Claims

### Claim 1

A method of system information transmissions performed by a user equipment (UE), the method comprising:
receiving a system information (SI) scheduling information list for a plurality of SI messages and a random access resource list for a plurality of SI requests via a system information block type 1 (SIB1), wherein each entry of the SI scheduling information list comprises an SI broadcast status indication of whether an SI message of the plurality of SI messages is on-demand or broadcast; and
determining, when a plurality of random access resource entries exist in the random access resource list for the plurality of SI requests including a first SI request and a second SI request, that a first entry of the plurality of random access resource entries in the random access resource list for the first SI request corresponds to a first entry in the SI scheduling information list, the SI broadcast status indication being configured as on-demand in the first entry in the SI scheduling information list, and that a second entry of the plurality of random access resource entries in the random access resource list for the second SI request corresponds to a second entry in the SI scheduling information list, the SI broadcast status indication being configured as on-demand in the second entry in the SI scheduling information list.

### Claim 2 (depends on 1)

A user equipment (UE) for performing system information transmissions, the UE comprising:
a processor; and
a memory, storing instructions, wherein
when executed by the processor, the instructions execute the method according to claim 1.

### Claim 3

A method of system information transmissions performed by a base station (BS), the method comprising:
transmitting a system information (SI) scheduling information list for a plurality of SI messages and a random access resource list for a plurality of SI requests via a system information block type 1 (SIB1), wherein
each entry of the SI scheduling information list comprises an SI broadcast status indication of whether an SI message of the plurality of SI messages is on-demand or broadcast, and
when a plurality of random access resource entries exist in the random access resource list for the plurality of SI requests including a first SI request and a second SI request, a first entry of the plurality of random access resource entries in the random access resource list for the first SI request corresponds to a first entry in the SI scheduling information list, the SI broadcast status indication being configured as on-demand in the first entry in the SI scheduling information list, and a second entry of the plurality of random access resource entries in the random access resource list for the second SI request corresponds to a second entry in the SI scheduling information list, the SI broadcast status indication being configured as on-demand in the second entry in the SI scheduling information list.

### Claim 4 (depends on 3)

A base station (BS) for performing system information transmissions, the BS comprising:
a processor; and
a memory, storing instructions, wherein
when executed by the processor, the instructions execute the method according to claim 3.
