Transmission method and system of physical control format indicator channel

Abstract

The invention discloses a transmission method and a system of a physical control format indicator channel. The method comprises the steps that a transmitting side conducts simplex code coding processing, modulation, pre-coding processing and reprocessing to a physical control format indicator according to preset coding speed; for each transmitting antenna, reference signals and data which is obtained after reprocessing are mapped to the physical resource blocks of the transmitting antenna according to the preset resource mapping scheme of the physical control format indicator channel and then are transmitted; each receiving antenna conducts resource extraction of the physical control format indicator channel to the received data and reference signals according to the preset resource mapping scheme, space channel vectors from a serving base station and an interference base station to the receiving antenna according to the obtained reference signals, space channel matrices are constructed and interference elimination matrices are obtained accordingly; and the data transmitted by the interference base station is eliminated according to the interference elimination matrices and a detection criteria and the physical control format indicator is obtained through processing inverse to the processing of the transmitting side.

Description

technical field [0001] The present invention relates to the communication field, and in particular to a physical control format indicator channel (Physical Control Format Indicator Channel, PCFICH for short) transmission method and system, and a physical control format indicator channel sending device and receiving device. Background technique [0002] The data rate provided by the existing cellular mobile communication system has a large difference between the center of the cell and the edge of the cell. This difference will not only affect the capacity of the entire system, but also cause a large difference in the quality of service obtained by users in different locations. , thereby affecting the user experience. Therefore, many wireless communication systems regard improving cell edge performance as one of the main demand indicators. [0003] Inter-Cell Interference (ICI for short) is an inherent problem in the cellular mobile communication system, and the traditional s...

Problems solved by technology

[0015] Aiming at the problem in the related art that the receiver cannot demodulate the physical control format indication due to strong inter-cell interference on the physical control format indication channel, which affects normal communication, the present invention proposes a transmission method and system for the physical control format indication channel, and a physical control format indication channel. The sending device and the receiving device of the control format indication channel can effectively eliminate and reduce the influence of inter-cell interference on the physical control format indication channel, so that the receiver can correctly detect and receive the physical control format indication information, and help to correctly detect the downlink control channel
