Embodiment Construction

[0021] figure 1 is a simplified diagram of an exemplary wireless communication network 10 comprising three isolated clusters of cells 12-14, where each cluster of cells comprises one or more base stations, e.g., enhanced Node Bs serving a plurality of user equipments (UEs) 22 (eNB) 16-21. An eNB 16-21 typically includes an antenna, a radio transmitter, a radio receiver, and a processor that provides resource management and logic control functions. The term user equipment or UE is used herein to refer to any mobile device that is configured to operate and communicate in a wireless environment and may include a wide variety of devices including, but not limited to, wireless transmit / receive units, cellular Phones, tablets, smartphones, computers, network nodes, etc.

[0022] The concept of cell clusters is proposed as a method of interference mitigation (IM) for LTE time division duplex (TDD), where asymmetric uplink (UL) and downlink (DL) resources are allocated. Each cell c...

Abstract

A wireless communication method for establishing and maintaining a cell cluster comprising at least one cell configured to communicate with at least one UE (User Equipment) is provided, the method comprising detecting a broadcast beacon signal. The method further includes, in response to the absence of the broadcast beacon signal, assuming the role of a cluster head for the cluster having the particular intra-cell identifier, and broadcasting a beacon signal. Responsive to detecting the broadcast beacon signal and the absence of the intra-cell identifier, transmission and reception continue using the previous duplex communication configuration. Further, in response to detecting the broadcast beacon signal and the presence of the intra-cell identifier, adding the cell identified by the detected intra-cell identifier, and setting the intra-cell identifier of the cell based on the detected intra-cell identifier identifier.

Description

technical field [0001] The present disclosure relates to the field of wireless communications, and more particularly, to systems and methods for establishing and maintaining clusters of cells. Background technique [0002] The 3rd Generation Partnership Project (3GPP) unites 6 telecommunication standards organizations called "Organizational Partners" and provides its members with a stable environment to produce very successful reports and specifications defining 3GPP technologies. Mobile devices, also referred to as user equipment (UE), may operate in wireless communication networks that provide high speed data and / or voice communications. Wireless communication networks may implement Circuit Switched (CS) and / or Packet Switched (PS) communication protocols to provide various services. For example, the UE may be based on a code division multiple access (CDMA) network, a time division multiple access (TDMA) network, a frequency division multiple access (FDMA) network, an ort...
