Abstract

The invention discloses a C-RNTI configuration method, device and system. Wherein, the method includes: obtaining the number of interfering cells corresponding to each cell in the cell set; determining the anti-interference configuration distance between the C-RNTIs of each terminal in each cell according to the number of interfering cells in each cell; The interference configuration interval configures the corresponding target C-RNTI for each terminal respectively. The invention solves the technical problem of high transmission bit error rate caused by directly allocating C-RNTIs in order in the prior art.

Description

technical field [0001] The present invention relates to the communication field, 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 Radio Network Temporary Identifier (C-RNTI, Cell Radio Network Temporary Identifier). When scheduling terminal users (UE, User Equipment), the base station relies on the transmission of downlink control information (DCI, Downlink Control Information) on the physical layer downlink control channel (PDCCH, Physical Downlink Control Channel), thereby notifying the UE of its receiving or sending signal Specific wireless resource location. [0003] At present, for the configuration of C-RNTI, the commonly used method is to configure C-RNTI for each small cell (SmallCell) after cell splitting, wherein, the C-RNTI configured by each terminal in each small cell The distance is 1. However, since the small...
