Problems solved by technology

[0009] Previously, addressing these coexistence issues was difficult with two-way communication systems deployed in paired and unpaired spectrum, as system designers had to make trade-offs between increased cost and / or performance impact

Embodiment Construction

[0022] The following description focuses on the following embodiments of the present invention, which are applicable to UMTS TM (Universal Mobile Communications System) cellular communication system and is especially applicable to the Third Generation Partnership Project (3GPP TM ) UMTS operating in any paired or unpaired spectrum within the system TM Terrestrial Radio Access Network (UTRAN). Furthermore, the following description focuses on embodiments of the present invention applicable to support broadcast transmission in 3G or 4G systems, for example when SFN technology is employed. However, it will be appreciated that the invention is not limited to this particular cellular communication system, but is applicable to any wireless communication system that may suffer from potential adjacent channel or inter-cell interference. However, in other examples the concept of the invention can be applied to adjacent channel TDD systems, for example in unsynchronized systems or whe...

Abstract

A method for reducing interference between a first wireless network element and a second wireless network element in a wireless communication system comprises, at the first wireless network element: receiving a downlink signal from the second wireless network element on a downlink channel associated with an uplink channel of the first wireless network element; and determining a signal quality level of the downlink signal from the second wireless network element. The method further comprises determining an interference potential between the first wireless network element and the second wireless network element from the measurement; and adapting a network parameter associated with the uplink channel of the first wireless network element in response to determining the interference potential.

Description

technical field [0001] The technical field of the invention relates to apparatus and methods for reducing interference in wireless communication systems. In particular, the technical field of the invention relates to identifying potential interference and adapting its communication (network parameters) characteristics or resources in order to reduce, for example, the 3rd Generation Partnership Project (3GPP TM ) potentially interfering wireless network elements in a Long Term Evolution (LTE) cellular communication system. Background technique [0002] During the 1980s and 1990s, second generation (2G) cellular communication systems were implemented to provide mobile telephone communications. Third generation (3G) cellular communication systems have since been widely installed to further improve the communication services available to mobile phone users. The most widely adopted third generation communication systems are based on Code Division Multiple Access (CDMA) and Freq...
