Abstract

The invention discloses a method for allocating / mapping PDCCH candidates / channel estimates and a terminal device. The method includes: if the total number of PDCCH candidates of the terminal device in the current time slot is greater than the maximum number of PDCCH candidates supported by the terminal device, or the number of PDCCH candidates required by the terminal device If the number of channel estimates exceeds the maximum number of channel estimates supported by the terminal device, allocate / map PDCCH candidates or channel estimates among multiple listening opportunities in the current time slot according to at least one type of information, the at least one type of information includes OFDM of the listening opportunities At least one of the symbol position, the priority of the scheduled cell associated with the search space set, the service priority, the channel priority, the DCI format corresponding to the PDCCH candidate monitored by the search space set, and the RNTI. The solutions of the embodiments of the present invention can make full use of the processing capability of the UE, maximize the allocation of control resources, reduce the blocking probability of control channel allocation, and ensure that the processing capability of the UE is not exceeded.

Description

technical field [0001] The present invention relates to the communication field / terminal field, and in particular to a PDCCH monitoring candidate allocation method and network side equipment. Background technique [0002] The 5G NR system supports configuring multiple control resource sets (ControlResource Set, CORESET) and multiple search space sets (Search Space Set) for the user equipment (User Equipment, UE), and flexibly configures the physical downlink control channel for each search space set (Physical Downlink Control Channel, PDCCH) candidate number. The monitoring of the search space set may be any one or more Orthogonal Frequency Division Multiplexing (OFDM) symbols in a time slot (slot), and the multiple search space sets may partially or completely overlap. The current protocol does not specify the allocation of PDCCH candidates or channel estimates. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a PD...
