Embodiment Construction

[0038] The base station of the first cell in the embodiment of the present invention sends the first interference power parameter value to the user terminal, which is used to instruct the user terminal to determine the adjacent cell interference value according to the first interference power parameter value, where the first interference power parameter value is used to determine The interference caused by the second cell to the user equipment in the first cell. Since the user terminal determines the adjacent cell interference according to the first interference power parameter value, the accuracy of interference estimation is improved.

[0039] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0040] like figure 2 As shown, the system for determining adjacent cell interference according to the embodiment of the present invention includes: the base station 10 and the user terminal 20 of the first...

Abstract

An embodiment of the invention relates to the wireless communication technology, especially relates to a method for determining neighboring cell interference, a system and an apparatus thereof. In the prior art, if a cell employs a resource element (RE) MUTING scheme, neighboring cell interference precision determined by a user terminal is low. The invention can solve the above problem. The method in the embodiment of the invention comprises the following steps that: s base station in a first cell determines a first interference power parameter value, wherein the first interference power parameter value is used for determining the interference generated by the user terminal in a second cell to the user terminal in the first cell; the base station in the first cell sends the first interference power parameter value to the user terminal so as to instruct the user terminal to determine a neighboring cell interference value according to the first interference power parameter value. By using the embodiment of the invention, the user terminal determines the neighboring cell interference according to the first interference power parameter value so that the precision of interference estimate can be raised.

Description

technical field [0001] The present invention relates to wireless communication technology, and in particular, to a method, system and device for determining adjacent cell interference. Background technique [0002] Each cell in a wireless cellular network system usually has one base station to communicate with the user terminal. Before the data transmission process starts, the base station sends reference signals (pilot signals) to the user terminal, and the user terminal obtains the channel estimation value according to these reference signals. A reference signal is a sequence of known signals that are scheduled to be sent at a specific time and on a specific frequency. Factors such as interference and noise can affect the quality of channel estimation. [0003] Usually, user terminals are located in different geographic locations, and have different received signal strengths and strengths of noise and interference. Therefore, some user terminals can communicate at a hig...
