Abstract

The invention discloses a cell ratio network temporary identifier configuration (C-RNTI) method, apparatus, and system. The method comprises: the number of interference cells corresponding to each cell in a cell set is obtained; according to the number of the interference cells of each cell, anti-interference configuration intervals between C-RNTIs of all terminals in each cell are determined; and corresponding target C-RNTIs are configured to all terminals respectively based on the anti-interference configuration intervals. Therefore, a technical problem of a high transmission error rate caused by direct C-RNTI distribution according to a sequence in the prior art can be solved.

Description

Technical field [0001] The present invention relates to the field of communications, and in particular to a C-RNTI configuration method, device and system. Background technique [0002] On the access side of the LTE system, that is, the air interface, each user is distinguished by a cell temporary user identifier (C-RNTI, CellRadioNetworkTemporaryIdentifier). When scheduling a terminal user (UE, User Equipment), the base station relies on the physical layer downlink control channel (PDCCH, Physical Downlink Control Channel) to transmit downlink control information (DCI, Downlink Control Information), thereby notifying the UE of the specific radio resource location of the received or transmitted signal . [0003] At present, for the configuration of C-RNTI, the common way is to configure the C-RNTI for each small cell (SmallCell) separately after the cell is split. Among them, the difference between the C-RNTI configured by each terminal in each small cell is The distance is 1. H...
