摘要： A method and apparatus for a co-scheduler can mitigate UE-to-UE adjacent carrier frequency band interference by allocating three sets to a first user equipment uplink. Each set has at least one sub-carrier in a first frequency band, at least one uplink time period, and at least one transmission power parameter. The co-scheduler initially allocates the first set. The co-scheduler allocates the second set in response to detecting a second user equipment operating proximal to the first user equipment, and the second set differs from the first set in either at least one sub-carrier or at least one transmission power parameter. The co-scheduler allocates the third set in response to detecting that the second user equipment is no longer operating proximal to the first user equipment, and the third set differs from the second set in either at least one sub-carrier or at least one transmission power parameter.

摘要： A method (500) and apparatus for multi-radio coexistence has a victim user equipment (UE) that receives (515) a sequence of subframes at a first transceiver from a serving base station, measures (520) channel state on the subframes to obtain channel state measurements, determines (530) a high-low interference pattern based on the channel state measurements, and transmits (550) to the serving base station a report that includes an indicator related to the high-low interference pattern. The method can include the victim UE receiving (610) an aggressor reference waveform (ARW) from the second transceiver, determining (620) spatial characteristics of the second transceiver from the ARW, and configuring (630) its antenna system based on the spatial characteristics. The method can have the victim UE determining (640) second transceiver characteristics from the ARW and transmitting (650) information regarding the second transceiver characteristics to its serving base station.

摘要： The present invention provides for wireless terminal and a method in a wireless terminal for use in a location determination approach using time of arrival estimates between the wireless terminal and a plurality of base stations in a cellular network. The method includes receiving assistance data from a serving base station for use in receiving a position reference signal used to determine a time of arrival of one or more respective position reference signals from the plurality of base stations relative to a time reference, wherein the assistance data includes a list of base stations, each base station included in the list to be one of used or excluded from use as part of the plurality of base stations for receiving the position reference signal and determining the time of arrival estimate for the received position reference signal. The position reference signal is then received for each of the plurality of base stations, where for each of the plurality of base stations a time of arrival estimate is determined for each of the respective received position reference signals. The time of arrival estimates for each of the plurality of base stations is then forwarded to a location determination entity.

摘要： A method (300) for radio link control padding is shown. In its simplest form, it can include the steps of: providing (310) N bytes of data from a base station; interleaving (320) the N bytes of data using a turbo-interleaver; pre-pending (330) K bytes of zero padding; and passing (340) the interleaved N bytes and the pre-pended K bytes to a convolutional encoder to provide an output comprising a parity sequence adapted for further processing and providing a radio link control block for an enhanced general packet radio service 2-B mobile device. The method (300) is particularly adapted for use with Chase and incremental redundancy combining, which can provide fast, reliable and efficient general packet radio service to a 2-B mobile device.
