Systems and methods for providing interference characteristics for interference suppression

Abstract

According to some embodiments, methods and systems include providing, by a network node, interference characteristic data to a first wireless device for use in performing interference mitigation. A method of providing interference characteristic data by a network node may include providing telecommunications services to a first wireless device associated with the network node. Characteristic data associated with at least one characteristic of the interfering signal associated with the second wireless device may be identified by the network node. Characteristic data associated with the interfering signal associated with the second wireless device may be communicated to the first wireless device. The at least one characteristic may identify a precoder assignment configured for at least one physical resource block pair associated with an interfering signal.

Description

technical field [0001] Certain embodiments relate generally to wireless communications and, more particularly, to systems and methods for providing interference characteristics for interference mitigation. Background technique [0002] To meet higher capacity requirements and to enhance user experience, cellular communication networks are increasing the number of base stations employed. One way to increase base station density is by segmenting macro cells in high-load geographic areas. In particular, a macro cell may be split into multiple small cells in high loaded geographic areas. These high-load areas can be regarded as service hotspots within the coverage area of ​​the macro cell. This densification of the underlying support for cellular networks may allow reuse of radio resources. Additionally, the wireless device can achieve higher bit rates because the wireless device may be closer to the serving base station. [0003] Another way to meet high capacity requiremen...

Problems solved by technology

[0021] However, different types of receivers may require different information and / or parameters, and different types of receivers are required to blindly estimate all parameters required for a receiver implementation

Additionally, the numerous communication standards applicable to LTE may include many features that need to be supported by the wireless device but will not be used by the network (depending on the configuration) and can make blind detection difficult and complex

Currently, signaling is not defined in the LTE standard to provide wireless devices with the assistance needed to implement advanced receivers with limited complexity
