Embodiment Construction

[0024] First, although certain embodiments are discussed in the context of wireless networks operating in accordance with the 3rd Generation Partnership Project ("3GPP") evolution, such as the Long Term Evolution ("LTE") standard, the present invention is not limited to This is applicable to other broadband networks, including those operating according to Orthogonal Frequency Division Multiplexing ("OFDM")-based systems, including WiMAX (IEEE 802.16) and Ultra Mobile Broadband ("UMB"), among others. network. Similarly, the present invention is not limited to OFDM-based systems, and may be implemented in accordance with other system technologies, such as Code Division Multiple Access ("CDMA"), Single-Carrier Frequency Division Multiple Access ("SC-FDMA"), etc. .

[0025] It is worth noting that although the term "base station" is used here, it should be understood that these devices can also refer to "eNodeB" or "eNB" devices in the long term evolution. Accordingly, use of th...

Abstract

A method and system for identifying cell clusters within a coordinated multiple point wireless transmission network in order to reduce scheduling complexity while optimizing throughout and performance. The network includes a total number of cells served by corresponding base stations. The BSC divides the entire network of cells into clusters of cells and forwards this clustering information to all mobile devices. A cluster of cell candidates is a subset of the total number of cells within the network. The mobile device then provides to a base station controller the identity of a cluster of preferred cells selected from the cluster of cell candidates. The base station controller selects at least one base station located within the cluster of preferred cells to establish communication with the mobile device. A wireless connection is then established between the selected at least one base station and the mobile device.

Description

technical field [0001] The present invention relates generally to wireless communications, and more particularly to a mobile-centric clustering system and method for coordinated multi-point transmission and reception. Background technique [0002] In the dynamic world of wireless communications, as the capacity and speed of mobile communications networks improve, technological advancements continue to occur to enable mobile device users to enjoy consistent and high-quality performance. While this generation of mobile telecommunications networks, collectively referred to as the third generation ("3G"), is still in vogue, the next generation of mobile telecommunications technology, known as Long Term Evolution ("LTE"), is labeled as the fourth generation ("4G") ), is about to emerge. Accordingly, there is an increased need and interest for a system that can meet the technical requirements of this new generation of mobile communications and that can provide a method of increas...
