Problems solved by technology

[0004] In the new generation of communication technology, the monitoring cycle of the terminal monitoring PDCCH may be less than one time slot, that is, in the scenario of multiple PDCCH monitoring opportunities in the same time slot, use the time slot number and RNTI to determine the initial control channel unit of the USS index, it will cause two UEs to have monitoring conflicts in the PDCCH search space

Abstract

The invention discloses a method, device, storage medium and processor for determining search space resources of a physical downlink control channel. The method includes: acquiring an accumulated value k according to attribute information of a physical downlink control channel PDCCH, wherein the attribute information includes at least one of the following: orthogonal frequency division multiplexing OFDM symbol information, monitoring opportunity information, and time slot information ; Determine the index value of the control channel element CCE in the PDCCH search space according to the accumulated value k. The determination of the initial control channel element index of the USS whose monitoring period is less than one time slot is realized, thereby avoiding the monitoring conflict between two terminals in the search space in the scenario of multiple PDCCH monitoring opportunities in the same time slot.

Description

technical field [0001] The invention relates to communication technology, in particular to a method, device, storage medium and processor for determining search space resources of a physical downlink control channel. Background technique [0002] In the Long Term Evolution (LTE for short) technology, the terminal needs to perform blind detection on the Physical Downlink Control Channel (PDCCH for short), so as to obtain the downlink control information (Downlink Control Information, DCI for short), where the DCI includes scheduling information for instructing the terminal to carry downlink data on the downlink shared channel. That is to say, the terminal can obtain the scheduling information of the physical shared channel PDSCH according to the downlink control information carried by the physical downlink control channel PDCCH, and then receive the downlink data information carried on the physical shared channel PDSCH according to the scheduling information. [0003] In the...
