Abstract:

A system and method for wirelessly communicating using beamswitching is provided. A communications system includes a high-power signal cable coupled to a signal amplifier, a radio frequency circuit coupled to the high-power signal cable, and a control unit coupled to the radio frequency circuit. The high-power signal cable conveys a transmission signal produced by the signal amplifier. The radio frequency circuit includes a plurality of antennas, a passive network having a plurality of output ports and a plurality of input ports, each output port coupled to an antenna of the plurality of antennas, and a plurality of switches coupled to the high-power signal cable, each switch coupled to an input port in the plurality of input ports. The control unit produces the control signal based on a specified coupling of the high-power signal cable to the passive network.

International Classification:

H04B 17/02

US Classification:

455132, 455230, 455436, 4551601

Abstract:

A system and method for enhanced parallel receiving interworking in a wireless communications network. A method for controller operation where the controller serves a communications device having at least two receivers includes detecting that the communications device has at least one receiver tuned to a current radio access technology (RAT) and at least one receiver tuned to an alternate RAT, adjusting a network parameter to alter the communication network's performance, and readjusting the network parameter back to its original value in response to determining that the communications device no longer has any receiver tuned to the alternate RAT. The adjusted network parameter impacts only the communications device.

Abstract:

System and method for unsynchronized cooperative spectrum sensing in cognitive radio nodes. A method comprises receiving spectrum sensing information from a plurality of communications nodes, computing for each communications node in the plurality of communications nodes, a likelihood ratio based on spectrum sensing information provided by the communications node, combining the likelihood ratios, and computing a decision value based on the combined likelihood ratio. Each communications node determines its respective spectrum sensing information at a time unrelated to times when other communications nodes determine their spectrum sensing information.

International Classification:

H04W 72/00

US Classification:

455450, 4554522, 455453, 343853

Abstract:

A method for coordinating beam forming between two communicating entities includes obtaining cell loading information and adjusting a number of used beam-sets at a specific scheduling time according to the cell loading information. The method further includes transmitting a common pilot that is not beam-formed together with feed-forward information according to the cell loading. A wireless communication system employing conventional CL-MIMO protocols can be adapted to employ the methodology.

US Classification:

455454, 455423, 455 6711, 4551151

Abstract:

System and method for scheduling spectrum sensing in cognitive radio systems. A method comprises sensing an availability of a spectrum band, computing a duration of an inter-sensing time block based on the availability of the spectrum band, and scheduling an occurrence of the spectrum sensing operation using the duration of the inter-sensing time block. Computing the duration of the inter-sensing time block based on the availability of the spectrum band allows for an optimization of communications of the cognitive radio system, thereby increasing spectral efficiency and reducing interference to licensed communications.

US Classification:

455 634, 455 25, 343757

Abstract:

System and method for exploiting spatial spectrum holes (SSH) in the time/spectrum/location of wireless resources. A method comprises setting a directional antenna to a first transmission direction, determining a state of a spectrum band in the first transmission direction, transmitting information in the first transmission direction to the receiver in response to determining that the spectrum band state is idle and that the receiver lies within a coverage area of a transmitter, and transmitting the information in the first transmission direction to a first relay in response to determining that the spectrum band state is idle and that the receiver lies without the coverage area of the transmitter.
