  • Reference transport channel on/off status detection and reselection
    Patent number: 7453862
    Abstract: In a wireless communication system using a reference channel used for error rate measurement and associated with a plurality of transport channels multiplexed on a coded composite transport channel (CCTrCH), a method is employed for reselection of the reference channel from favorable candidate transport channels. A channel is initially selected from the plurality of multiplexed channels as the reference channel. Channels are monitored based on quantitative data content criteria to determine whether an ON or OFF state exists. A different channel is selected from the plurality of multiplexed channels as the reselected RTrCH when a better candidate transport channel in the ON state becomes available, or when the monitored RTrCH reflects an OFF state.

  • Wireless user equipment for use in reducing cross cell interference
    Patent number: 7450905
    Abstract: A method for reducing cross cell interference in a wireless time division duplex communication system using code division multiple access, the system having at least one user equipment (UE) and a base station (BS) is disclosed. The method begins by measuring an interference level of each timeslot at the BS. A timeslot is eliminated for additional uplink communication if the measured interference level exceeds a first threshold. An interference level of each timeslot is measured at the UE, and the timeslot is eliminated for downlink communication for the UE if the measured interference level exceeds a second threshold. UEs in nearby cells that are large interferers are identified and their downlink timeslot usage is gathered. A timeslot is eliminated for uplink communication for a large interferer UE that uses the timeslot for downlink communication.

  • Escape mechanism for a wireless local area network
    Patent number: 7450904
    Abstract: A method for changing a channel in a wireless local area network (WLAN) to alleviate congestion and high interference levels, the WLAN having an access point (AP) and at least one station, begins by determining a list of candidate channels. A channel is selected from the candidate list and is evaluated against predetermined criteria. If the selected channel meets the predetermined criteria, then all of the stations communicating with the AP are disassociated and the AP is changed to the selected channel. If the selected channel does not meet the predetermined criteria, then the selected channel is removed from the candidate list and the selecting step is repeated if there are additional candidate channels.

  • Reverse link pilot integrated with block codes
    Patent number: 7447187
    Abstract: A technique for encoding digital communication signals. Data symbols are augmented in pilot symbols inserted at predetermined positions. The pilot augmented sequence is then fed to a deterministic error correction block encoder, such as a turbo product coder, to output a coded sequence. The symbols in the error correction encoded sequence are then rearranged to ensure that the output symbols derived from input pilot symbols are located at regular, predetermined positions. As a result, channel encoding schemes can more easily be used which benefits from power of two length block sizes.
