Embodiment Construction

[0041] As mentioned in the background, in the prior art, the priority order of candidate PDCCHs in the same search space type and in the same search space set has not been determined yet.

[0042] The inventors of the present application found that, in the existing solution, the priority of the candidate PDCCHs to be monitored in the search space set can be determined based on the radio network temporary identities (Radio Network Tempory Identity, RNTI). However, there are many kinds of RNTIs involved in different search space sets, but in fact RNTIs do not affect the number of blind detections. When the number of blind detection times and the number of CCEs used for channel estimation exceed the capability of the UE, determining the priority of the search space set based on the RNTI cannot improve the efficiency of the blind detection of the UE.

[0043] In the technical solution of the present invention, the number of non-overlapping CCEs in the search space set is positivel...

Abstract

A method, device, storage medium, base station, and terminal for determining and monitoring the priority of a candidate PDCCH. The method for determining the priority of a candidate PDCCH includes: for the same type of search space set, according to the number of non-overlapping CCEs in each search space set Determine the first priority of the search space set; for search space sets with the same first priority, according to the size of the identifier of each search space set and / or the format of the downlink control information in each search space set A second priority is determined for the set of search spaces. The technical solution of the present invention can configure the priority of PDCCH in the search space set of the same type, so that the UE monitors the PDCCH according to the configured priority, and improves the success rate of blind detection.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device, storage medium, base station, and terminal for determining the priority of candidate PDCCHs and monitoring them. Background technique [0002] In the fifth-generation mobile communication technology (5th-Generation, 5G) new air interface (New radio, NR) system, the maximum number of physical downlink control channel (Physical Downlink Control Channel, PDCCH) candidates is a function of the subcarrier spacing. When the subcarrier spacing is 15, 30, 60, and 120 kHz respectively, correspondingly, the maximum number of candidate PDCCH (PDCCH candidate) 44, 36, 22, 20 respectively. in, It refers to the maximum number of times of blind detection in one time slot, including all aggregation levels (Aggregation Level, AL) and downlink control information (Downlink Control Information, DCI) formats (DCI format for short). A terminal (User Equipment, UE...
