Embodiment Construction

[0022] In order to make the objectives, technical solutions and advantages of the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely intended to illustrate the invention and are not intended to limit the invention.

[0023] Example embodiments provide a method of non-serving cell uplink interference is reduced, to address non-serving RL failure cause inner loop power control interference lifting non-serving cell of the present invention. The method mainly comprising: a non-serving RL where the base station (hereinafter referred to as non-serving NODEB) at a predetermined fixed period M imbalance detection uplink scenario, after the detection, reducing the transmission to the serving base station where RL (hereinafter referred to as service NODEB) said signal to interference target of the service station where RL...

Abstract

The present invention relates to a communication link control method and device. The base station where the serving wireless link is located receives a request for reducing the target signal-to-interference ratio of the base station where the serving wireless link is located, which is sent by the base station where the serving wireless link is located. The request includes reducing the target signal-to-interference ratio reduction amount of the base station where the serving wireless link is located; according to the request, the base station where the serving wireless link is located is reduced by the reduction amount The target signal-to-interference ratio of the base station. In the present invention, the base station where the non-serving wireless link is located identifies the scene where the uplink and downlink unbalanced power control fails, and notifies the base station where the serving wireless link is located, and the base station where the serving wireless link is located reduces the transmission power of the device by reducing its target signal-to-interference ratio. It can reduce the uplink interference of non-serving cells, improve the throughput of non-serving cells and improve the signal quality of non-serving wireless links in the scenario of unbalanced uplink and downlink in macro-diversity.

Description

Technical field [0001] The present invention relates to a universal mobile telecommunication system, and more particularly, to a method and apparatus for controlling a communication link. Background technique [0002] 3Gpp (ie 3rd Generation Partnership Project, Third Generation Partnership Project) protocol R5 (ie Release5,3GPP specification is named Release5, release version, abbreviated to R5) introduced a high-speed downlink packet access (High Speed ​​Downlink Packet Access, after referred to as HSDPA) technology, greatly enhance the user download data rate. R6 version introduced in HSUPA (High Speed ​​Uplink Packet Access, referred to as HSUPA) technology has greatly enhanced the uploading data rate users. [0003] Universal Mobile Telecommunications System (Universal Mobile Telecommunications System, referred to as UMTS), Wideband Code Division Multiple Access in particular (Wideband Code Division Multiple Access, referred to as WCDMA) 3G (3rd Generation), there is an imba...
