摘要： A method allocates resources in an orthogonal frequency-division multiple access (OFDMA) network including a set of base stations (BSs), and a set of mobile stations (MSs) for each BS. Each cell includes a center and edge zone. A node weighted constraint graph is constructed for the network. Maximal independent sets in the graph are searched as sub-channels are allocated to the MSs in edge zones. Remaining bandwidth is allocated to the MSs in the center zones. Power is assigned to the sub-channels so that inter-cell interference is minimized and traffic load is maximized.

摘要： A method allocates resource in an Orthogonal Frequency-Division Multiple Access (OFDMA) network, including a set of Base Stations (BSs) and a set of Mobile Stations (MSs) for each BS. OFDMA frame are constructed as multiple resource blocks, and each resource block contains symbols transmitted on different subcarriers. A cluster is formed from adjacent sectors of different neighboring cells to jointly optimize the resource allocation in multiple frames, and three non-overlap zones are sequentially identified in cluster: cell center zone, cell edge zone, and cluster corner zone. Resource allocation includes intra-cluster proportional fair scheduling and inter-cluster interference mitigation. Intra-cluster scheduling further includes resource allocation for cell center zone and resource allocation for cell edge zone.

摘要： A method and system provide multiple-access control and frequency band allocation, and transmission time sharing among multiple users in orthogonal frequency-division multiple-access (OFDMA) and time-division multiple-access (TDMA) networks. The method can be applied to uplinks and downlinks of multi-user, multi-carrier communication networks. Under a total transmission-power minimization constraint, the method can allocate carriers and transmission time to users optimally, and at the same time, can guarantee a data rate or equivalently a latency requirement of each user.

摘要： A method selects antennas in an OFDMA network. A channel state of a downlink is measured using a downlink subframe received in a mobile station from a base station. A channel state of an uplink is measured using an uplink subframe received in the base station from the mobile station. Next, the method compares the channel states to determine whether the downlink and the uplink are reciprocal or not. The mobile station can perform receive antenna selection based on the quality of the downlink channel state. The mobile station can also perform transmit antenna selection when instructed by the base station.

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.

摘要： A method selectively acknowledges data packets in a network including a multiple stations connected by a common wireless channel. A transmitting station requests a block acknowledgement from a receiving station. The transmitting station transmits a block of data packets to the receiving station. The receiving station determines a number of successfully received data packets and a number of incorrectly received packets. Then, the receiving station selectively acknowledges only the successfully received data packets if the number of usefully received data packets is less than the number of incorrectly received data packets, and otherwise acknowledging only the incorrectly received packets.
