    Abstract: An information configuration method, an information configuration apparatus and a communication system, wherein the method includes: the base station configures a user equipment (UE) with a mapping relation between configuration information of one or more sets of reference signals and indication information indicating the configuration information according to an antenna port formed by virtualizing a two-dimensional planar antenna array. By configuring the UE with the configuration information by the base station according to the antenna port formed by virtualizing the two-dimensional planar antenna array, the configuration information is adaptive to the two-dimensional planar antenna array, such that the user end accurately acquires the configuration information of the array.

    Abstract: A communication method and apparatus at an unlicensed band. One of the methods includes: an eNB transmits request information respectively to a small cell and UE connected to the eNB, requesting the small cell and the UE to measure a candidate channel on the unlicensed band; the eNB negotiates with the small cell for operational parameters of the small cell according to measurement results reported by the small cell and UE; and the eNB transmits the operational parameters of the small cell negotiated by the eNB with the small cell to the UE, so that the UE accesses to the small cell according to the operational parameters of the small cell and performs data transmission, transmitting data on the unlicensed band, the small cell may select a working channel having minimum interference on other neighboring systems and subjected to minimum interference from the other neighboring systems at the UE side.

    Abstract: A data transmission method and system, transmitter and receiver. The method includes: mapping, by a transmitter, a plurality of data streams to a plurality of antennas of the transmitter by using precoding matrices and transmitting the plurality of data streams to a receiver via the plurality of antennas, wherein the transmitter selects the precoding matrices by taking a resource block as a granularity. With the embodiments of the present invention, the transmitter may transmit data streams to the receiver by using the precoding matrices W, and selects the precoding matrices W by taking a resource block (RB) as a granularity, so as to support DM-RS demodulation, and the receiver is not needed to perform PMI feedback, which is also applicable to a scenario where user feedback is not supported or PMI feedback is inaccurate, thereby achieving open-loop spatial multiplexing CoMP transmission.
