20110170467METHOD AND APPARATUS FOR ALLOWING SOFT HANDOFF OF A CDMA REVERSE LINK UTILIZING AN ORTHOGONAL CHANNEL STRUCTURE - Method and apparatus for base stations and subscriber units allows soft handoff of a CDMA reverse link utilizing an orthogonal channel structure. Subscriber units transmit an orthogonally coded signal over a reverse link to the base stations. A given base station provides timing control of the timing offset of the reverse link signal. Based on at least one criterion, an alignment controller determines that the given base station should hand off timing control to another base station, and a soft handoff process ensues. In response to a command or message for soft handoff of the subscriber unit from the given base station to another base station, the subscriber unit makes a coarse timing adjustment to the timing of the coded signal. The subscriber unit may make fine timing adjustments based on feedback from the base station controlling timing. Multiple base stations may provide power control feedback to the subscriber unit.07-14-2011

20090213905USE OF ORTHOGONAL OR NEAR ORTHOGONAL CODES IN REVERSE LINK - An apparatus for use with a shared access communication channel is disclosed. The chipping rate of a first group of terminals is determined. Transmissions on the shared access communication channel are encoded using first pseudorandom noise (PN) code and a phase shift at the first chipping rate and an orthogonal spreading code having a chipping rate less than the first chipping rate. The apparatus may receive a feedback channel assignment and may receive an indication of a change in timing on the assigned feedback channel.08-27-2009

Patent application numberDescriptionPublished
20100026576METHOD FOR MEASURING THE TIME OF ARRIVAL OF RADIO SIGNALS - A method for measuring the time of arrival of radio signals within a network comprises receiving the received signals including at least a first pseudorandom code and a second pseudorandom code from at least one other node; identifying a frequency difference between the node and the other node using a phase difference between each of a maximum value of a cross-correlation provided by the first pseudorandom code and the second pseudorandom code; applying the frequency difference to the reception of the received signal; and calculating the time of arrival of the received signal comprising a time, measured with a local clock, when the cross-correlation has achieved the maximum value.02-04-2010
20110133996ANTENNA FEEDING MECHANISM - An access point is provided with an electronics enclosure which is surrounded by antenna panels. An antenna feeding mechanism operates using spatial multiplexing multiple input multiple output. Three radio frequency chains are used in a pattern that feeds a total of eight antenna elements. Multiple streams are supported by using two polarizations. Additionally a maximal ratio combiner is used to combine signals from different antennas. The hardware within the access point supports three radio frequency chains which are mapped to four antenna panels, each panel containing two elements; one for vertical and one for horizontal polarization.06-09-2011
