OG exemplary drawing
 
1. A terminal device, comprising a processor and a memory, wherein the memory is configured to store a program executable on the processor, and the program, when executed by the processor, causes the processor to:
receive first indication information transmitted by a network device; and
obtain one or more channel access parameters based on the first indication information, the one or more channel access parameters being used for determining channel access for a target uplink transmission,
wherein the first indication information comprises: mode information indicating a channel access mode comprising Category 4 (Cat-4) Listen Before Talk (LBT);
wherein the target uplink transmission comprises Message 3 in a random access procedure;
wherein the first indication information is carried in a Random Access Response (RAR) message; and
wherein the first indication information being carried in the RAR message comprises: the first indication information occupying 2 bits in a RAR grant field in the RAR message.
 
7. A network device, comprising a processor and a memory, wherein the memory is configured to store a program executable on the processor, and the program, when executed by the processor, causes the processor to :
transmit first indication information to a terminal device, the first indication information being used for obtaining one or more channel access parameters,
wherein the one or more channel access parameters are used for determining channel access for a target uplink transmission;
wherein the first indication information comprises: mode information indicating a channel access mode comprising Category 4 (Cat-4) Listen Before Talk (LBT);
wherein the target uplink transmission comprises Message 3 in a random access procedure;
wherein the first indication information is carried in a Random Access Response (RAR) message; and
wherein the first indication information being carried in the RAR message comprises: the first indication information occupying 2 bits in a RAR grant field in the RAR message.
 
13. A network device, comprising a processor and a memory, wherein the memory is configured to store a program executable on the processor, and the program, when executed by the processor, causes the processor to:
transmit first indication information to a terminal device, the first indication information being used for obtaining one or more channel access parameters,
wherein the one or more channel access parameters are used for determining channel access for a target uplink transmission;
wherein the first indication information comprises: mode information indicating a channel access mode comprising Category 4 (Cat-4) Listen Before Talk (LBT);
wherein the target uplink transmission comprises Message 3 in a random access procedure;
wherein the first indication information is carried in a Random Access Response (RAR) message; and
wherein the first indication information being carried in the RAR message comprises: the first indication information being obtained by reusing a part of bits in a Physical Uplink Shared Channel (PUSCH) frequency resource allocation field in a RAR grant field in the RAR message.
