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 present application discloses a terminal blind detection method, device and equipment. In this application, according to the channel environment where the target terminal is located in the current search space update period and the downlink PDCCH resources that the target terminal is scheduled to use, the average aggregation level assigned to the target terminal in the current search space update period can be determined, so that according to the average The aggregation level allocates a new dedicated search space for the target terminal. Among the aggregation levels included in the dedicated search space, there are at least a first aggregation level that is close to and greater than the average aggregation level, and a first aggregation level that is similar to the average aggregation level A second aggregation level that is close to and smaller than the average aggregation level, through which the dedicated search space can be used to dynamically allocate a suitable dedicated search space for the target terminal according to the channel environment where the target terminal is located, without needing to use the dedicated search space based on the 5G specification every time All aggregation levels perform blind detection to improve the efficiency of terminal blind detection.

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...
