摘要： A method selects antennas in a wireless network including a base station and one or more transceivers. The base station specifies times, subcarriers and subsets of antennas to use to transmit sounding reference signals (SRS) to the base station. Then, the transceiver transmits the SRS according to the specified times and subcarriers using different subsets of the set antennas. The SRS are received in the base station, and the base station selects one of the different subset of the antennas based on the received SRS, and indicates the selected subset of the antennas to the transceiver.

摘要： A method selects antennas in an OFDMA wireless network including a base station and a mobile station. The mobile station measures a channel state of a downlink in a downlink subframe using different subsets of available antennas, and selects a subset of receive antennas for downlink reception based on the channel states between the base station and the different subsets of antennas at the mobile station. The base station measures the channel state in an uplink using an uplink subframe received in the base station from the mobile station, and selects a subset of transmit antennas for mobile station's uplink transmission based on the channel states between the base station and different subset of antennas at the mobile station.

摘要： A method routs a packet from a source node, via relay nodes, to a destination node. The nodes are connected by wireless links x. A channel power gain γ is measured for each link x. Resource trade-off curves y=f(x) are constructed for each link x from the channel power gains γ, wherein y represents a set of resources. A hyperbolic upper bound h/x+c is fitted to each resource curve, such that h/x+c≧f(x), wherein h is a scale factor, and c is an offset. A route with an optimal resource allocation is selected according to the hyperbolic upper bounds. Then, the packet is transmitted from the source node to the destination node using the route.

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 for identifying a leading edge time period of a received radio signal includes identifying a greatest energy time period in a sequence of time periods. The received radio signal has a greatest average energy in the greatest energy time period. The method also includes identifying a least energy time period in the sequence of time periods. The received radio signal has a least average energy in the least energy time period. Further, the method includes setting a threshold energy based on the greatest average energy and the least average energy, determining a number of window time periods based on a characteristic of a radio channel used by the received radio signal, and identifying as a leading edge time period an earliest time period that precedes the greatest energy time period within the number of window time periods. The received radio signal in the leading edge time period has an average energy greater than or equal to the threshold energy.
