Abstract

The invention discloses a PDCCH candidate / channel estimation number distribution / mapping method and terminal equipment. The method comprises the following steps: 1, if the total number of the PDCCH candidates of the terminal equipment in the current time slot is greater than the maximum number of the PDCCH candidates supported by the terminal equipment, or the channel estimation number required bythe terminal equipment exceeds the maximum channel estimation number supported by the terminal equipment, allocating / mapping PDCCH candidates or channel estimates among a plurality of monitoring opportunities of the current time slot according to the at least one piece of information, wherein the at least one piece of information comprises at least one of an OFDM symbol position of a monitoring opportunity, a scheduled cell priority associated with a search space set, a service priority, a channel priority, a DCI format corresponding to a PDCCH candidate monitored by the search space set, andan RNTI. According to the scheme provided by the embodiment of the invention, the processing capacity of the UE can be fully utilized, the control resource allocation is maximized, the control channel allocation blocking probability is reduced, and meanwhile, the processing capacity 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...
