    摘要： A method allocates bandwidth from a radio frequency spectrum in a cellular network including a set of cells. Each cell includes a base station for serving a set of mobile stations in the cell. An area around each base station is partitioned into a center region and an edge region. In each base station, cell-center bandwidth for use by the mobile stations in the center region is reserved according to an inter-cell interference coordination (ICIC) protocol, and cell-edge bandwidth for use by the mobile stations in the edge region is reserved according to the ICIC protocol. The bandwidth can be fixed or adaptive to reduce the signaling overhead. The adaptive bandwidth can be further partitioned into reserved and the free bands. Mobile stations are classified as primary and secondary users, depending on whether they use or are assigned the fixed or adaptive band radio resources.

    摘要： A method allocates bandwidth from a radio frequency spectrum in a cellular network including a set of cells. Each cell includes a base station for serving a set of mobile stations in the cell. An area around each base station is partitioned into a center region and a boundary region. In each base station, bandwidth for use in the center region is reserved according to an inter-cell interference coordination (ICIC) protocol, and bandwidth for use in the boundary region is reserved according to the ICIC protocol and a base station cooperation (BSC) protocol. Then, the bandwidth is allocated to mobile stations as the mobile stations communicate with the base station in the center regions and the boundary regions according to the bandwidth reservations.

    摘要： A method and system enables and improves performance of hybrid automatic repeat request (HARQ) operations on channels between stations of an orthogonal frequency division multiple access (OFDMA) wireless communication network. There, the number of parallel HARQ channels is increased adaptively, and one connection identifier is used to unambiguously identify a set of MAC protocol data units (MPDUs) communicated over parallel HARQ channels. A sequence number is used to avoid out-of-order MPDU delivery when MPDUs are transmitted over parallel HARQ channels. The MPDUs can be concatenated or encapsulated. The maximum number of the parallel HARQ channels can be increased to 256, and can be negotiated when a station enters or re-enters the network.

    摘要： A method accesses channels in an OFDMA mobile multihop relay wireless network. The method partitions a downlink sub-frame into at least one downlink access zone and a set of downlink relay zones. The uplink subframe is partitioned into at least one uplink access zone and a set of uplink relay zones. During the downlink access zone, the base station and the relay stations transmit only to the set of mobile stations. During the downlink relay station, the base station and the set of relay stations communicate with each other, while the mobile stations are idle. During the uplink access zone, the set of mobile stations transmit only to the set of relay stations and the base station. During the uplink relay station, the base station and the set of relay stations communicate with each other, while the mobile stations are idle.
