In the communication enhancement scene, the existing scheme obtains the number of PDCCH candidates which can be monitored in a time slot/span and the threshold value of non-overlapping CCE resources which can be monitored according to configuration information aiming at the scene in which a transmission point serves as a terminal.

And aiming at two transmission point scenes, obtaining the number of PDCCH candidates which can be monitored in one time slot/span and the threshold value of non-overlapping CCE resources which can be monitored according to the configuration information. When the PDCCH candidate/non-overlapping CCE in one slot/span is higher than a threshold value, it is necessary to explicitly monitor the PDCCH in which PDCCH candidates. And the PDCCH needs to be explicitly monitored in the resources corresponding to the non-overlapping CCEs, so that the transmission accuracy is improved.

The high-level configuration information comprises a first type search space set and a second type search space set, the second type search space set corresponds to the first transmission point and the second transmission point, and the first type search space set corresponds to the third transmission point.

Wherein the number of target PDCCH candidates and/or target non-overlapping CCEs is not more than the maximum number M of PDCCH candidates or the maximum number N of non-overlapping CCEs within one slot or one span. The maximum number M of PDCCH candidates or the maximum number N of non-overlapping CCEs in a slot or a span may be determined in a predefined manner, or may be determined by higher layer configuration information, which is not specifically limited herein.

S203, the network equipment sends the PDCCH through the resources corresponding to the target PDCCH candidate and the target non-overlapping CCE.

The network device may also obtain high-level configuration information, and determine a target PDCCH candidate and a target non-overlapping CCE in one time slot or span according to the high-level configuration information, where a specific implementation method of the method is the same as that of the method in which the network device determines the target PDCCH candidate and the target non-overlapping CCE in one time slot or span.

If each time slot corresponding to the USS5 and the USS7 corresponds to a first transmission point and a second transmission point, if the number of maximum PDCCH candidates in one time slot is 19, the first set includes USS2, and the second set includes USS3, it may be determined that PDCCH candidates corresponding to the USS5, the USS7, and the USS2 are target PDCCH candidates; for another example, if the maximum number of PDCCH candidates in one slot is 16, the second set includes USS3 and USS2, and the first set is empty, so that the PDCCH candidates corresponding to USS5 and USS7 can be determined as target PDCCH candidates.

b3, determining PDCCH candidates corresponding to the first subset and the fourth set as the target PDCCH candidates and non-overlapping CCEs corresponding to the first subset and the fourth set as target non-overlapping CCEs;

In the method, after the number B1 of the PDCCH candidates corresponding to the second-type search space set is determined to be greater than M, the target PDCCH candidates are directly determined from the second-type search space set. Determining the target non-overlapping CCE is the same as the method of determining the target PDCCH candidate.

c3, if the sum of the number A2 of non-overlapping CCEs corresponding to the first type of search space set and the number B2 of non-overlapping CCEs corresponding to the second type of search space set is larger than N, determining that the non-overlapping CCEs corresponding to the first set and the second set of search space set are target non-overlapping CCEs;

In the above embodiment, it can be understood that the target PDCCH candidate and the target non-overlapping CCE are determined according to the search space set identifier from low to high.
