Abstract
Provided are a method and device for transmitting MSG3 in a random access procedure in a wireless communication system. A user equipment (UE) determines a frequency resource for transmitting MSG3 in a random access procedure and transmits the MSG3 to a network via the frequency resource. The starting position of the frequency resource is the smallest physical resource block (PRB) of an active uplink (UL) bandwidth part (BWP), and the bandwidth of the frequency resource is the same as the bandwidth of an initial UL BWP.
Claims13
A method for transmitting MSG3 of a random access procedure by a wireless device in a wireless communication system, the method comprising:
- determining a frequency resource for transmission of the MSG3 within an active uplink (UL) bandwidth part (BWP) other than an initial UL BWP, wherein the frequency resource for transmission of the MSG3 within the active UL BWP starts from a lowest physical resource block (PRB) of the active UL BWP, and wherein a bandwidth of the frequency resource for transmission of the MSG3 within the active UL BWP is determined based on a bandwidth of the initial UL BWP;
- and
- transmitting, to a network, the MSG3 through the frequency resource within the active UL BWP.
A wireless device configured to operate in a wireless communication system, the wireless device comprising:
- at least one transceiver;
- at least one processor;
- and
- at least one computer memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
- determining a frequency resource for transmission of MSG3 of a random access procedure within an active uplink (UL) bandwidth part (BWP) other than an initial UL BWP, wherein the frequency resource for transmission of the MSG3 within the active UL BWP starts from a lowest physical resource block (PRB) of the active UL BWP, and wherein a bandwidth of the frequency resource for transmission of the MSG3 within the active UL BWP is determined based on a bandwidth of the initial UL BWP;
- and
- transmitting, to a network via the at least one transceiver, the MSG3 through the frequency resource within the active UL BWP.
A method for receiving MSG3 of a random access procedure by a base station (BS) in a wireless communication system, the method comprising:
- receiving, from a wireless device, the MSG3 through a frequency resource for reception of the MSG3 within an active uplink (UL) bandwidth part (BWP) other than an initial UL BWP,
- wherein the frequency resource for reception of the MSG3 within the active UL BWP starts from a lowest physical resource block (PRB) of the active UL BWP, and
- wherein a bandwidth of the frequency resource for reception of the MSG3 within the active UL BWP is determined based on a bandwidth of the initial UL BWP.
