Method for determining random access resource, terminal device, and network device

A method for determining a random access resource, comprising:

• determining, by a network device, Quasi Co-Located (QCL) information of a target Synchronization Signal Block (SSB);
• and
• determining, by the network device, a set of target random access resources corresponding to the QCL information of the target SSB based on a correspondence between QCL information of SSBs and sets of random access resources, wherein a random access resource in the set of target random access resources is used for the network device to receive a Random Access Channel (RACH),
• wherein said determining, by the network device, the QCL information of the target SSB comprises:
• determining, by the network device, the QCL information of the target SSB based on a position index of the target SSB and a parameter Q, wherein the parameter Q represents a maximum number of SSBs transmitted within a transmission window of a Discovery Reference Signal (DRS), and the SSBs transmitted within the transmission window of the Discovery Reference Signal (DRS) do not have a QCL relationship.

A terminal device, comprising:

• a processor;
• and
• a memory,
• wherein the memory is configured to store a computer program, and the processor is configured to invoke and run the computer program stored in the memory to:
• determine Quasi Co-Located (QCL) information of a target Synchronization Signal Block (SSB);
• and
• determine a set of target random access resources corresponding to the QCL information of the target SSB based on a correspondence between QCL information of SSBs and sets of random access resources, wherein a random access resource in the set of target random access resources is used for the terminal device to perform a random access process,
• wherein the processor is further configured to invoke and run the computer program stored in the memory to determine the QCL information of the target SSB based on a position index of the target SSB and a parameter Q, wherein the parameter Q represents a maximum number of SSBs transmitted within a transmission window of a Discovery Reference Signal (DRS), and the SSBs transmitted within the transmission window of the Discovery Reference Signal (DRS) do not have a QCL relationship.

A network device, comprising:

• a processor;
• and
• a memory, wherein the memory is configured to store a computer program, and the processor is configured to invoke and run the computer program stored in the memory to:
• determine Quasi Co-Located (QCL) information of a target Synchronization Signal Block (SSB);
• and
• determine a set of target random access resources corresponding to the QCL information of the target SSB based on a correspondence between QCL information of SSBs and sets of random access resources, wherein a random access resource in the set of target random access resources is used for the network device to receive a Random Access Channel (RACH), wherein the computer program invoked and run by the processor to determine the QCL information of the target SSB further causes the processor to invoke and run the computer program stored in the memory to:
• determine the QCL information of the target SSB based on a position index of the target SSB and a parameter Q, wherein the parameter Q represents a maximum number of SSBs transmitted within a transmission window of a Discovery Reference Signal (DRS), and the SSBs transmitted within the transmission window of the Discovery Reference Signal (DRS) do not have a QCL relationship.
