  • Patent number: 9585171
    Abstract: A method for operating a sharing station includes receiving, by the sharing station, a request to send (RTS) frame on a wireless channel, wherein the RTS frame is not addressed to the sharing station, and wherein the RTS frame including a transmit only indicator indicating that a transmitting station of the RTS frame will only transmit frames without receiving frames until expiration of a first time value in a first duration field of the RTS frame. The method also includes determining, by the sharing station, if a clear to send (CTS) frame corresponding to the RTS frame is received within a specified time period after receiving the RTS frame, and transmitting, by the sharing station, a frame when the CTS frame corresponding to the RTS frame is not received within the specified time period.

  • Patent number: 9571292
    Abstract: An approach is described for routing data to a plurality of output terminals via a integrated switch router including a crossbar switch having both a crossbar and a plurality of crossbar bypass lines. Whereas the crossbar may connect each input of the crossbar switch to each output of the crossbar switch, each of the plurality of crossbar bypass lines may connect a single input of the crossbar switch to a corresponding single output of the crossbar switch. According to such approach, a replicated copy of a multicast packet may be forwarded to an output terminal via a crossbar bypass line in parallel with other data forwarded via the crossbar, thus increasing integrated switch router bandwidth.

  • Patent number: 9560572
    Abstract: An originating transceiver node provides wireless service to a wireless communication device that is transmitting uplink signals within originating uplink time periods assigned to the originating transceiver node. A target transceiver node is assigned target uplink time periods for uplink communication from wireless communication devices receiving wireless service from the target transceiver node where the target uplink time periods are different from the originating uplink time periods. The target transceiver node monitors the originating uplink time periods and transmits a message if an uplink signal is received within an originating uplink time slot. In some circumstances, the target transceiver node sends the message only if a determination is made that the wireless communication device transmitting the uplink signal has a proximity to the target transceiver node that is less than a threshold.

  • Patent number: 9526093
    Abstract: A method and apparatus for requesting and allocating bandwidth in a broadband wireless communication system. The method and apparatus includes a combination of techniques that allow a plurality of CPEs to communicate their bandwidth request messages to respective base stations. One technique includes a “polling” method whereby a base station polls CPEs individually or in groups and allocates bandwidth specifically for the purpose of allowing the CPEs to respond with bandwidth requests. The polling of the CPEs by the base station may be in response to a CPE setting a “poll-me bit” or, alternatively, it may be periodic. Another technique comprises “piggybacking” bandwidth requests on bandwidth already allocated to a CPE. Currently active CPEs request bandwidth using unused portions of uplink bandwidth that is already allocated to the CPE. The CPE is responsible for distributing the allocated uplink bandwidth in a manner that accommodates the services provided by the CPE.

  • Patent number: 9485182
    Abstract: Various methods are provided to address the need for improved load balancing. In a one method, a packet loss is determined (101) for traffic sent between a first network node and a second network node. The determined packet loss is then used to determine (103) whether to perform load balancing. In another method, a first network node receives a request from a neighboring network node for a current loading status of the first network node. The first network node sends to the neighboring network node an indication of a backhaul loading level of the first network node.

  • Patent number: 9473277
    Abstract: Provided is a radio communication device which can prevent interference between SRS and PUCCH when the PUCCH transmission bandwidth fluctuates and suppress degradation of CQI estimation accuracy by the band where no SRS is transmitted. The device includes: an SRS code generation unit (201) which generates an SRS (Sounding Reference Signal) for measuring uplink line data channel quality; an SRS arrangement unit (202) which frequency-multiplexes the SRS on the SR transmission band and arranges it; and an SRS arrangement control unit (208) which controls SRS frequency multiplex so as to be uniform in frequency without modifying the bandwidth of one SRS multiplex unit in accordance with the fluctuation of the reference signal transmission bandwidth according to the SRS arrangement information transmitted from the base station and furthermore controls the transmission interval of the frequency-multiplexed SRS.
