    Abstract: Disclosed is a method and apparatus for transmitting and receiving a synchronization signal and a transmission system. In the method, a transmitting node determines a frequency band range in which a carrier is located, and configures or assumes synchronization channel information on the carrier according to the frequency band range, where the synchronization channel information includes at least one of: a subcarrier spacing or orthogonal frequency division multiplexing (OFDM) symbol information of a synchronization channel; and the transmitting node transmits the synchronization signal using the synchronization channel information.

    Abstract: Disclosed are a method and system for configuring a Physical Multicast Channel (PMCH), a method and system for acquiring a PMCH configuration and a method and system for sending and receiving subframes based on the PMCH configuration. The configuration method includes the following step: a base station configuring information for the PMCH or a Multimedia Broadcast and Multicast Service (MBMS) through a high-layer signalling and/or a predefinition and/or a Multicast Control Channel (MCCH). The configured information is at least one of a transmission band, a frequency-domain location, an initial location of an Orthogonal Frequency Division Multiplexing (OFDM) symbol of the PMCH, a transmission subframe cluster of the PMCH, a number of transmission layers or used port indexes and a number of ports of the PMCH and MBMS reference signal pattern information.

    Abstract: Disclosed is a method for configuring a channel state information (CSI) feedback. The method comprises: configuring multiple sets of CIS processes for a terminal, where each CSI process comprises at least information on a channel measurement part and information on an interference measurement, where the information on the channel measurement part comprises one or multiple sets of nonzero power CSI reference signal configuration or indication information, and where the information on the interference measurement part comprises at least one type of information among the following: one or multiple sets of interference measurement resource configuration information or indication information, one or multiple sets of nonzero power CSI reference signal configuration information for use in interference measurement compensation. Also disclosed are a method for measurement and feedback based on the method, and a corresponding device for implementing the method. The present invention implements unified configuration and reception of the CSI feedback for a base station-side and a terminal-side, and is capable of flexibly implementing CSI configuration and feedback.
