Pdcch monitoring method, pdcch sending method, and related device

A Physical Downlink Control Channel (PDCCH) sending method, performed by a network side device, comprising:

• sending first information to a terminal;
• and
• sending a PDCCH repetition based on the first information;
• wherein
• the first information comprises at least one of the following:
• a first parameter, wherein the first parameter is used to indicate PDCCH repetition information, wherein the PDCCH repetition information comprises at least one of the following:
• times of PDCCH repetition, a monitoring occasion of the PDCCH repetition, or duration of each PDCCH repetition;
• a second parameter, wherein the second parameter is used to indicate whether to perform the PDCCH repetition;
• a third parameter, wherein the third parameter is used to indicate P search spaces for the PDCCH repetition, and P is a positive integer;
• or
• a fourth parameter, wherein the fourth parameter is used to indicate Q Control Resource Sets (CORESETs) for the PDCCH repetition, and Q is a positive integer.

A terminal, comprising:

• a memory having a computer program stored thereon;
• and a processor, wherein the computer program, when executed by the processor, causes the processor to perform a Physical Downlink Control Channel (PDCCH) monitoring method, comprising:
• obtaining first information;
• and
• monitoring a PDCCH repetition based on the first information, wherein
• the first information comprises at least one of the following:
• a first parameter, wherein the first parameter is used to indicate PDCCH repetition information, wherein the PDCCH repetition information comprises at least one of the following:
• times of PDCCH repetition, a monitoring occasion of the PDCCH repetition, or duration of each PDCCH repetition;
• a second parameter, wherein the second parameter is used to indicate whether to perform the PDCCH repetition;
• a third parameter, wherein the third parameter is used to indicate P search spaces for the PDCCH repetition, and P is a positive integer;
• or
• a fourth parameter, wherein the fourth parameter is used to indicate Q Control Resource Sets (CORESETs) for the PDCCH repetition, and Q is a positive integer.
