Abstract

In a wireless communication system, user equipment (UE) receives information about an uplink (UL) bandwidth part (BWP) from a network through remaining minimum system information (RMSI), and transmits an MSG 3 of a random access procedure to the network through the UL BWP. The UL BWP can be configured separately from a downlink (DL) BWP.

First claim

1 . A method for operating a user equipment (UE) in a wireless communication system, comprising:
receiving information on an uplink (UL) bandwidth part (BWP) from a network through remaining minimum system information (RMSI); and transmitting a MSG 3 of a random access procedure to the network through the UL BWP.

2 . The method of claim 1 , wherein the UL BWP is configured separately from a downlink (DL) BWP.

3 . The method of claim 1 , wherein the information on the UL BWP includes information on a frequency where the UL BWP is located.

4 . The method of claim 3 , wherein the information on the frequency of the UL BWP includes information on an offset from a specific UL frequency.

5 . The method of claim 4 , wherein the specific UL frequency is a subcarrier having index 0 of a given numerology.

6 . The method of claim 3 , wherein a bandwidth of the UL BWP is the same as a UE minimum bandwidth.

7 . The method of claim 3 , wherein the information on the UL BWP further includes information on a bandwidth of the UL BWP.

8 . A user equipment (UE) in a wireless communication system, comprising:
a memory; a transceiver; and a processor connected to the memory and the transceiver, and configured to: control the transceiver to receive information on an uplink (UL) bandwidth part (BWP) from a network through remaining minimum system information (RMSI); and control the transceiver to transmit a MSG 3 of a random access procedure to the network through the UL BWP.

9 . A method for operating a base station in a wireless communication system, comprising:
transmitting information on an uplink (UL) bandwidth part (BWP) to a user equipment (UE) through remaining minimum system information (RMSI); and receiving a MSG 3 of a random access procedure from the UE through the UL BWP.

10 . The method of claim 9 , wherein the UL BWP is configured separately from a downlink (DL) BWP.

11 . The method of claim 9 , wherein the information on the UL BWP includes information on a frequency where the UL BWP is located.

12 . The method of claim 11 , wherein the information on the frequency of the UL BWP includes information on an offset from a specific UL frequency.

13 . The method of claim 12 , wherein the specific UL frequency is a subcarrier having index 0 of a given numerology.

14 . The method of claim 11 , wherein a bandwidth of the UL BWP is the same as a UE minimum bandwidth.

15 . The method of claim 11 , wherein the information on the UL BWP further includes information on a bandwidth of the UL BWP.

16 . The method of claim 1 , wherein the UE is in communication with at least one of a mobile device, a network, and/or autonomous vehicles other than the UE.
