Problems solved by technology

[0003] However, in related technologies, the base station does not notify the terminal of the aggregation level it is assigned to use when transmitting DCI, but only issues the search space for blind detection to the terminal. The search space includes each aggregation level of the 5G protocol specification. When the terminal performs blind detection, sometimes it is necessary to traverse all the aggregation levels of the 5G protocol specification, resulting in relatively low efficiency of blind detection

Abstract

The embodiment of the invention discloses a terminal blind detection method and device and equipment. According to the invention, the average aggregation level allocated and used by a target terminal in a current search space updating period can be determined according to the channel environment of the target terminal in the current search space updating period and the downlink PDCCH resource scheduled and used by the target terminal; therefore, a new special search space is allocated to the target terminal according to the average aggregation level; the aggregation levels included in the special search space at least comprise a first aggregation level which is close to and greater than the average aggregation level and a second aggregation level which is close to and less than the average aggregation level; through the special search space, the appropriate special search space can be dynamically allocated to the target terminal according to the channel environment where the target terminal is located, and blind detection does not need to be carried out based on all aggregation levels of the 5G specification every time, so that the blind detection efficiency of the terminal is improved.

Description

technical field [0001] The present application relates to the communication field, and in particular to a terminal blind detection method, device and equipment. Background technique [0002] In the 5G specification, before the base station performs data interaction with the terminal, it needs to transmit the downlink control information (DCI, Downlink Control Channel) used to instruct the terminal to interact with the base station to the terminal, and the transmission of DCI is allocated to the terminal through the base station. The downlink PDCCH resource (Physical Downlink Control Channel, physical downlink control channel) used by the terminal is implemented; wherein, the size of the downlink PDCCH resource allocated to the terminal is called an aggregation level. [0003] However, in related technologies, the base station does not notify the terminal of the aggregation level it is assigned to use when transmitting DCI, but only issues the search space for blind detection...
