Problems solved by technology

The existing time-division multiplexing scheme of PBCH is not suitable for demodulation based on DMRS, because when all DMRS ports are used for demodulation of PBCH, it will reduce the physical downlink shared channel (PDSCH) time-division multiplexed with PBCH. ) for the flexibility of the transfer mode

Abstract

The present invention provides a method performed by a base station, including: generating a codeword sequence including system information of the base station; modulating the codeword sequence to generate a physical broadcast channel PBCH sequence; For each PBCH, select a physical resource block PRB; and perform mapping between the PBCH and resource elements RE in the selected PRB. Wherein, the PRB has a distributed PRB frequency division multiplexing format or a centralized PRB frequency division multiplexing format. The present invention also provides a method for user equipment and the corresponding base station and user equipment. By adopting the present invention, the energy utilization rate in the LTE-Advanced system can be improved, the frequency spectrum efficiency can be improved, and the time / frequency resource conflict between cells can be reduced.

Description

technical field [0001] The invention relates to the technical field of wireless communication. More specifically, the present invention relates to a method for sending and receiving system information of a serving cell, a base station and user equipment. Background technique [0002] The Long Term Evolution (LTE) project deployed by the 3rd Generation Partnership Project (3GPP) aims to provide increasingly diverse communication services, of which packet voice communication is a part. In the first version of 3GPP LTE (ie, Release 8), Orthogonal Frequency Division Multiple Access (OFDMA) and Multiple Antenna (MIMO) technologies were introduced. The Release 10 version of 3GPP has been evaluated and tested by the International Telecommunication Union, and has officially become the fourth-generation global mobile communication standard LTE-Advanced. In the LTE-Advanced standard, carrier aggregation (CA) and relay technology are introduced, the uplink / downlink MIMO technology is...
