Communication method and apparatus for random access procedure

A communication method, applicable to a first terminal device or a chip in the first terminal device, and the method comprising:

• receiving configuration information of a first initial uplink bandwidth part (BWP) of the first terminal device from a network device;
• receiving first information from the network device, wherein the first information indicates a first frequency domain resource for sending a third message (Msg3) in a random access procedure, wherein the first frequency domain resource is in a frequency domain range of the first initial uplink BWP;
• and
• determining the first frequency domain resource based on the first information and a second initial uplink BWP of a second terminal device, wherein the determining the first frequency domain resource based on the first information and the second initial uplink BWP comprises:
• determining a start location of the first frequency domain resource and a length of the first frequency domain resource based on the first information, the first initial uplink BWP, and a first offset value, wherein the first offset value is a frequency domain offset value between a start location of the first initial uplink BWP and a start location of the second initial uplink BWP.

An apparatus, comprising:

• one or more processors;
• and
• one or more non-transitory memories coupled to the one or more processors and storing programming instructions that, when executed by the one or more processors, cause the apparatus to perform:
• receiving configuration information of a first initial uplink bandwidth part (BWP) of the first terminal device from a network device;
• receiving first information from the network device, wherein the first information indicates a first frequency domain resource for sending a third message (Msg3) in a random access procedure, wherein the first frequency domain resource is in a frequency domain range of the first initial uplink BWP;
• and
• determining the first frequency domain resource based on the first information and a second initial uplink BWP of a second terminal device, wherein the determining the first frequency domain resource based on the first information and the second initial uplink BWP comprises:
• determining a start location of the first frequency domain resource and a length of the first frequency domain resource based on the first information, the first initial uplink BWP, and a first offset value, wherein the first offset value is a frequency domain offset value between a start location of the first initial uplink BWP and a start location of the second initial uplink BWP.
