Abstract

Claims (55)

1 . A user equipment (UE) in a wireless communication system, the UE comprising:

a transceiver; and

a controller coupled with the transceiver and configured to:

receive, from a base station (BS), first information configuring a non-cell-defining synchronization signals and physical broadcast channel (SS/PBCH) block (NCD-SSB),

receive, from the BS, second information configuring a random access channel which is dedicated for UEs associated with the NCD-SSB, and

receive, from the BS, the NCD-SSB based on the first information,

wherein the NCD-SSB is different from a cell-defining SS/PBCH block (CD-SSB) which is associated with remaining minimum system information (RMSI), and

wherein a power related value of the NCD-SSB is same as a power related value of the CD-SSB.

2 . The UE of claim 1 , wherein the NCD-SSB is received in a radio resource control (RRC) connected state or an RRC inactive state, and

wherein the first information includes at least one of

a first value for a frequency of the NCD-SSB,

a second value for a periodicity of the NCD-SSB, or

a third value for a time offset between the CD-SSB and the NCD-SSB.

3 . The UE of claim 1 ,

wherein the CD-SSB and the NCD-SSB with a same index have a same quasi co-located (QCL) property, and

wherein, for a half-duplex UE, a symbol for a reception of the NCD-SSB is not used for an uplink transmission.

4 . The UE of claim 2 , wherein the first information includes the second value for the periodicity of the NCD-SSB.

5 . The UE of claim 2 , wherein the first information includes the first value for the frequency of the NCD-SSB.

6 . The UE of claim 2 , wherein the first information includes the third value for the time offset between the CD-SSB and the NCD-SSB.

7 . A base station (BS) in a wireless communication system, the BS comprising:

a transceiver; and

a controller coupled with the transceiver, and configured to

transmit, to a user equipment (UE), first information configuring a non-cell-defining synchronization signals and physical broadcast channel (SS/PBCH) block (NCD-SSB),

transmit, to the UE, second information configuring a random access channel which is dedicated for UEs associated with the NCD-SSB, and

transmit, to the UE, the NCD-SSB based on the first information,

wherein the NCD-SSB is different from a cell-defining SS/PBCH block (CD-SSB) which is associated with remaining minimum system information (RMSI), and

wherein a power related value of the NCD-SSB is same as a power related value of the CD-SSB.

8 . The BS of claim 7 , wherein the NCD-SSB is transmitted in a radio resource control (RRC) connected state or an RRC inactive state, and

wherein the first information includes at least one of

a first value for a frequency of the NCD-SSB,

a second value for a periodicity of the NCD-SSB, or

a third value for a time offset between the CD-SSB and the NCD-SSB.

9 . The BS of claim 7 , wherein the CD-SSB and the NCD-SSB with a same index have a same quasi co-located (QCL) property, and

wherein, for a half-duplex UE, a symbol for a reception of the NCD-SSB is not used for an uplink transmission.

10 . The BS of claim 7 ,

wherein the CD-SSB and the NCD-SSB with a same index have a same quasi co-located (QCL) property, and

wherein, for a half-duplex UE, a symbol for a reception of the NCD-SSB is not used for an uplink transmission.

11 . The BS of claim 8 , wherein the first information includes the first value for the frequency of the NCD-SSB, the second value for the periodicity of the NCD-SSB, and the third value for the time offset between the CD-SSB and the NCD-SSB.

12 . A method performed by a user equipment (UE) in a wireless communication system, the method comprising:

receiving, from a base station (BS), first information configuring a non-cell-defining synchronization signals and physical broadcast channel (SS/PBCH) block (NCD-SSB),

receiving, from the BS, second information configuring a random access channel which is dedicated for UEs associated with the NCD-SSB; and

receiving, from the BS, the NCD-SSB based on the first information,

wherein the NCD-SSB is different from a cell-defining SS/PBCH block (CD-SSB) which is associated with remaining minimum system information (RMSI), and

wherein a power related value of the NCD-SSB is same as a power related value of the CD-SSB.

13 . The method of claim 12 , wherein the NCD-SSB is received in a radio resource control (RRC) connected state or an RRC inactive state, and

wherein the first information is received via a UE specific RRC signaling, and includes at least one of

a first value for a frequency of the NCD-SSB,

a second value for a periodicity of the NCD-SSB, or

a third value for a time offset between the CD-SSB and the NCD-SSB.

14 . The method of claim 12 ,

wherein the CD-SSB and the NCD-SSB with a same index have a same quasi co-located (QCL) property, and

wherein, for a half-duplex UE, a symbol for a reception of the NCD-SSB is not used for an uplink transmission.

15 . The method of claim 13 , wherein the first information includes the second value for the periodicity of the NCD-SSB.

16 . The method of claim 13 , wherein the first information includes the first value for the frequency of the NCD-SSB.

17 . The method of claim 13 , wherein the first information includes the third value for the time offset between the CD-SSB and the NCD-SSB.
