Embodiment Construction

[0061] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0062] An embodiment of the present invention provides a signal receiving method, which is executed by a terminal. The scenario of the cellular communication system of the method is as follows: the system includes a serving base station, M co-channel interference base stations, a receiving terminal, and K relays. Where K is an integer greater than or equal to 1.

[0063] The system reception includes two time slots: in the first time slot, both the terminal and the K relays receive the signal from the serving base station and the interference signal from the base station adjacent to the same freque...

Abstract

The invention is suitable for the field of communication, and provides a signal reception method. The signal reception method comprises receiving first signals at a first slot time, receiving middle signals sent by multiple relay stations at a second slot time, and obtaining the estimated value of the vector quantity sent by a serving base station according to the first signals, the middle signals and a receiving matrix, wherein the first signals comprise useful signals sent by the serving base station and interference signals sent by the interference base station, and the middle signals are obtained by carrying out compression processing to the useful signals sent by the serving base station and received by a relay station and the interference signals sent by the interference base station through the relay station. The technical scheme of the signal reception method and the terminal has the advantage of being good in interference suppression effect.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a signal receiving method and a terminal. Background technique [0002] The downlink data transmission in the existing cellular communication system (that is, the data received by the terminal from the base station or access point) is actually limited by interference, that is, the interference signal of adjacent same-frequency cells is often 20-30dB higher than the power of channel noise . In the existing technologies, the interference of the cells of the same frequency is generally regarded as noise without suppression, or the interference is suppressed through a single terminal antenna. The former cannot reduce the impact of interference on downlink communication; while the latter has a poor interference suppression effect due to the limitation of the number of antennas (the number of antennas for a single terminal is often smaller than the number of interfering signal st...
