摘要： The embodiments of the invention provide an adaptive method for base station cooperation in a wireless network. In a multi-user communications network that includes base stations, and in which each base station is associated with a cell, and in which each cell includes one or more mobile stations, each base station determines pre-coding matrices for full-cooperation, semi-cooperation and non-cooperation. Each base stations also determines a sum rate SRfull for full-cooperation, a sum rate SRsemi for semi-cooperation, and a sum rate SRnon for non-cooperation. Then, each base station selects the pre-coding for full-cooperation, the pre-coding matrices for semi cooperation, or the pre-coding matrices for non cooperation. Each base station transmits signals according to the selected pre-coding matrices.

摘要： A method performs handover of a mobile station (MS from a current base station (BSC) connected to a target base station (BST) via a backbone in a Worldwide interoperability for Microwave Access (WiMAX) mobile communication network. The MS, before handover, transmits a Connection Identifier Request (CID-REQ) to the BST via the BSC, and receiving a Connection Identifier Response (CID-RSP) from the BST via the BSC. The MS, before handover, transmits a Subscriber Station (SS) Basic Capability Request (SBC-REQ), and receives a SS Basic Capability Response (SBC-RSP) from the BST via the BSC. Then, the MS transmits a Ranging Request (RNG-REQ) to the BST, and receives a Ranging Response (RNG-RSP) from the BST. During the handover, the MS transmits a Registration Request (REG-REQ) to the BST, and receives a Registration Response from the BST to establish the connection between the MS and the BST.

摘要： A method allocates frequency subchannels in an orthogonal frequency-division multiple access (OFDMA) network including a set of base stations and a set of mobile stations for each base station. A graph of nodes and edges is constructed, in which the nodes represent the mobile stations in the network, and the edges connecting the nodes represent subchannel allocation constraints to be satisfied for the mobile stations represented by the nodes. The nodes are colored with colors selected from a set of colors such that subchannel allocation constraints of a pair of nodes connected by one of the edges are satisfied. The subchannels are allocated to the mobile stations according to the colors of the corresponding the nodes.

摘要： A method allocates radio channel resource in an orthogonal frequency-division multiple access network including a set of base stations (BS) and a set of mobile stations (MS). For each BS, a diversity set is maintained for the sets of MS. Each BS determines possible interference at the MS based on the diversity set. A graph is constructed, in which nodes represent the sets of MS, and each edge between a pair of nodes represents channel interference between the MS represented by the pair of nodes. A weight is assigned to each edge, which reflects interference and signal strength on the subchannel between the two MSs connected by the edge. Channel resources are allocated to the MS based on the graph.
