    摘要： Techniques are provided for reducing interference in a wireless network. A user equipment device in a first wireless coverage area of a wireless network using a time division duplex transmission scheme to designate a maximum timing advance value for uplink transmissions based on potential interference between uplink transmissions made by the user equipment device in the first wireless coverage area or at least one other user equipment device in the first wireless coverage area, and downlink transmissions intended for at least one user equipment device in a second wireless coverage area of the wireless network. The maximum timing advance value may be based on relative cell radii or other cell properties of the first and second wireless coverage areas. A base station may determine the maximum timing advance and transmit the maximum timing advance to the user equipment device.

    摘要： The current invention provides simplifications to the user equipment (UE) radio front end module for the cellular handset or dongle through modification of the existing 3GPP specifications for LTE and WCDMA/HSPA+ in order to support half duplex (HD) operation. The option to support HD operation is provided without mandating upgrades to all existing base stations that have already been deployed. The instant invention further prevents HD UEs from attaching to any base stations which do not support HD operations. The instant invention further provides inter-frequency cell search periods for enabling HD UEs to communicate with any base stations/cells supporting the HD operations. The instant invention further enables the HSPA+ system to support the HD-FDD mode.

    摘要： Techniques are provided for decoding tail-biting convolutional codes by using information within the received data stream that traditionally has not been used or been available to the convolutional decoder, e.g., cyclic redundancy check (CRC) and bit information known by both the transmitter and receiver. Further, a single parallel trace-back is used that reduces implementation complexity. In addition, the least reliable decisions made during forward processing may be reversed in order to generate additional possible codeword candidates. These techniques can be used to reduce false detection rates (FDRs) and/or detection error rates (DERs).

    摘要： In a method for wireless data communication between a base station and a subscriber unit in a wireless communication system, groups of symbols of an input data stream are commutated to produce a plurality of commutated data streams. The plurality of commutated data streams are then transformed to produce a plurality of transformed data streams. Next, each transformed data stream is spread with a selected one of a plurality of spreading codes to produce a plurality of antenna signals. Finally, each of the plurality of antenna signals is transmitted using a selected one of a plurality of spaced apart antennas, wherein the plurality of spaced apart antennas are spaced apart to provide transmit diversity. In one embodiment, the transform is a space-time transform.

    摘要： Embodiments of techniques for low-cost multimode operation in wireless communications involving the Time Division Synchronous Code Division Multiple Access (TD-SCDMA) standard and the Global System for Mobile telecommunications (GSM) standard are described. In one aspect, a method of multimode operation in a mobile telecommunication device renders wireless communications based on the TD-SCDMA standard using either or both of first and second frequency synthesizers of the mobile telecommunication device. The method also receives signals based on the GSM standard using either or both of the first and second frequency synthesizers of the mobile telecommunication device. Techniques for performing baton handover as well as signal reception for multimedia broadcast and multicast services (MBMS) using two frequency synthesizers are also provided.
