    摘要: The present invention provides a method, base station, and user equipment for transmitting a control channel. Grouping is performed, according to an aggregation level of the to-be-transmitted control channel, on sub-blocks in physical resource blocks configured by the base station for the to-be-transmitted control channel, then interleaving is performed, and then candidate control channels are mapped to the interleaved sub-blocks, so that any candidate control channel of the to-be-transmitted control channel is sent on consecutive time-frequency resources as possible, and meanwhile different candidate control channels are on different PRB pairs as possible. In this way, the base station may have better flexibility during actual sending of the ePDCCH, thereby not only achieving a precoding gain and facilitating better transmission of control information, but also achieving a larger scheduling gain.

    摘要: Embodiments of the present invention provide an uplink power control method, a user equipment and a base station. The method comprises: receiving configuration information of a channel state information reference signal CSI-RS from the base station, wherein the configuration information of the CSI-RS comprises reference signal port information and reference signal power information; and measuring a path loss for uplink power control based on the configuration information of the CSI-RS. The embodiments of the present invention use the CSI-RS to measure the path loss, which differs from a common CRS in that the CSI-RS may aim at a specific base station. Therefore, path loss measurement may be performed in respect of a target base station of uplink transmission, enabling the path loss compensation to match the actual path loss, thus improving the performance of uplink power control.

    摘要: An information transmission method and apparatus are provided. In the method, a terminal device generates a first codeword, where the first codeword is obtained based on a second codeword, a quantity of elements included in the second codeword is greater than a quantity of elements included in the first codeword, the second codeword is associated with a first coefficient set of a downlink channel, and the first coefficient set includes an element included in at least one row vector or column vector of a first coefficient matrix; and then the terminal device feeds back the first codeword to a network device. The terminal device can indicate a position and a numerical value of an element in the first coefficient set by reporting only the first codeword. This manner is simple. In addition, a codeword length of the first codeword is shorter than a codeword length of the second codeword. Therefore, a quantity of bits required for reporting the first codeword by the terminal device is definitely less than a quantity of bits occupied for reporting at least one space-frequency combination coefficient, reducing overheads.

    摘要: This application provides a reference signal transmission method and an apparatus, used in a multipoint coordination transmission scenario. In the reference signal transmission method, a frequency domain resource that carries a target reference signal in a frequency domain resource or a time domain resource that is associated with each QCL assumption may be separately determined, and then the target reference signal carried on the frequency domain resource that is associated with the QCL assumption is separately received by using the corresponding QCL assumption. Therefore, each QCL assumption can be used to perform channel parameter estimation, and further, a channel parameter estimation result is used to assist a DMRS in performing channel estimation, thereby improving accuracy of channel estimation.
