INTERFERENCE SUPPRESSION METHOD AND RELATED DEVICE AND SYSTEM

摘要

Embodiments of the present invention disclose an interference suppression method and a related device and system. The method includes: sending, on a specified time-frequency resource, a first reference signal or a first reference signal group to an interfered-with end; receiving interfering source information sent by the interfered-with end, where the interfering source information includes an interference identifier used for indicating whether a potential interfering source causes interference to the interfered-with end; and if the interference identifier in the interfering source information indicates that the potential interfering source sending the reference signal on the specified time-frequency resource causes interference to the interfered-with end, determining that the potential interfering source is an interfering source, otherwise, determining that the potential interfering source is a non-interfering source. According to the present invention, mutual interference between uplink and downlink signals of terminals located in a same cell or different cells can be suppressed.

主权项

1. An interference suppression method, comprising:
receiving, by an interfered-with end, a first reference signal or a first reference signal group sent on a time-frequency resource by a base station or a relay station to which the interfered-with end belongs, wherein the interfered-with end is a user terminal or a relay station; receiving, by the interfered-with end, a second reference signal or a second reference signal group sent on the time-frequency resource by a potential interfering source; generating, by the interfered-with end, interfering source information according to signal strength of the first reference signal or the first reference signal group and signal strength of the second reference signal or the second reference signal group, wherein the interfering source information comprises an interference identifier used for indicating whether the potential interfering source causes interference to the interfered-with end; and sending the interfering source information to the base station or the relay station to which the interfered-with end belongs.
