Abstract: An interference power measurement method and a device are provided. The method includes: receiving, by a terminal, first signaling that carries first indication information, where the first indication information is used to indicate n first channel state information-reference signal CSI RS resources, and a jth first CSI RS resource is associated with a power parameter Pc,j; and sending, by the terminal, a channel quality indicator CQI, where the CQI is determined based on a total interference power. The total interference power is a linear weighting result of an interference power measured on each of the n first CSI RS resources and an interference power I0 measured on a zero power CSI RS resource. A weighting coefficient of an interference power Ij measured on the jth first CSI RS resource is a function of the power parameter Pc,j, and a weighting coefficient of I0 is a function of 1 - ∑ j = 1 n P c , j .

Abstract: A control information sending method, receiving method, and device are provided. The control information sending method includes: determining a first subframe of a first radio frame on a first carrier, where the first subframe includes a control region; sending control information in the control region of the first subframe of the first radio frame to a user equipment, where the control information includes a PDCCH; and sending an ePDCCH in a second subframe of the first radio frame to the user equipment. According to the embodiments of the present invention, when control information borne on an ePDCCH cannot be sent in a first radio frame, a PDCCH can still be sent to a user equipment through a control region in a first subframe, thereby achieving purposes of performing uplink/downlink scheduling for the user equipment and downlink feedback for uplink data of the user equipment.

Abstract: This application discloses a signal transmission method, including: mapping a first sequence into a first subcarrier group, and mapping a second sequence into a second subcarrier group. The subcarriers included in the first subcarrier group and the second subcarrier group are subcarriers on a same time domain symbol. The subcarriers in each of the first subcarrier group and the second subcarrier group are evenly distributed subcarriers. The first sequence is a Fourier transform sequence of a third sequence. The second sequence is a Fourier transform sequence of a fourth sequence. The elements at a same location in the third sequence and the fourth sequence are not both non-zero elements.

Abstract: A communication method, a base station, a radio communication node, and a user equipment are provided. A base station determines first resource configuration information, where the first resource configuration information is used for indicating N radio resource sets that are used when N radio communication nodes separately perform communication with a user equipment UE, and the radio resource includes a time domain resource and/or a frequency domain resource. The base station sends the first resource configuration information to the UE, where the UE communicates with a corresponding transmission point by using respective radio resource sets of transmission points, and the respective radio resource sets of the transmission points do not intersect. Therefore, a base station does not need to schedule a radio resource, thereby lowering a delay requirement on a backhaul link and eliminating interference.

Abstract: The present disclosure describes a message transmission method. In one example method, a first signal is received by a first device from a second device using a radio channel. A second signal, corresponding to and different from the received first signal, is transmitted by the second device to the first device. Information carried by the second signal corresponds to one of M state values. A first sequence corresponding to one or more subcarriers occupied by the second signal is directly proportional to a product of a preset second sequence and a third sequence in a state sequence set. Channel information of the radio channel is estimated by the first device according to the received first signal and the preset second sequence. The information carried by the second signal is determined by the first device according to the estimated channel information of the radio channel and the received first signal.
