    摘要： One method of wireless communication involves acknowledging that an anchor base station received a handover indication signal. Another method involves: receiving, from base stations of an active set, offset signals identifying a respective differences in time between a reference time and respective times when the base station received a ranging signal from a mobile station; and transmitting, to the mobile station, a ranging control signal in response to the respective offset signals. Another method involves transmitting, to a mobile station in response to an active set signal, a system configuration information signal including system configuration information of a base station in an active set. Another method involves determining an uplink control channel power parameter in response to channel condition signals received from base stations in an active set. Another method involves transmitting a control signal to base stations in an active set on respective control channels. Apparatuses are also disclosed.

    摘要： Apparatus and methods are provided for transitioning wireless devices between a plurality of states having increasing resource intensity from a least resource intensive state to a most resource intensive second state. All power-on wireless devices are ranked. A respective subset of the power-on wireless devices is assigned to each state, the power-on wireless devices of the subsets having rankings which increase with resource intensity of the state. Signalling is generated to the wireless devices to instruct them to implement any change in state. The priorities which are calculated for the purpose of state scheduling are preferably the same as those, or at least based upon the priorities used for packet scheduling.

    摘要： A method and system for a method of transmitting data within a signal frame. The method comprises inserting a first synchronization preamble into a first location within the signal frame and inserting a second synchronization preamble into a second location within the signal frame, wherein the first synchronization preamble conveys information indicative of the second location. The method further comprises issuing the signal frame towards a receiving device in a wireless communication environment.

    摘要： Methods and systems are provided for use with wireless networks having one or more cell in which each cell includes a base station (BS), at least one relay station (RS) and at least one mobile station (MS). The at least one relay station can be used as an intermediate station for providing communication between the BS and MS. Methods are provided for allocating OFDM resources for communicating between the BS, RS and/or MS for example dividing transmission resources into uplink and downlink transmissions and methods of inserting pilot symbols into transmission resources used by the RS. In some embodiments on the invention, the methods are consistent and/or can be used in conjunction with existing standards such as 802.16e.

    摘要： Systems and methods for MIMO wireless transmission are provided. At the transmitter, a plurality of encoded packets are modulated, and the symbols are divided between several transmit antennas. The transmitter spreads some of the symbols of each packet using a respective subset of an available Walsh code space. A given transmit antenna then transmits part of each packet spread by the respective subset. In some implementations, this achieves the benefits of the PARC system, and at the same time achieves part of the benefits of the STTD system. Advantageously, only a single reverse link control channel is required if adaptive coding and modulation is to be performed.

    摘要： A wireless communications network includes a mobile station and base station communicating an indicator of an autonomous data rate supportable over a reverse wireless link between the mobile station and base station. The mobile station and base station also communicate a flag indicating whether autonomous is enabled for the mobile station. In response to the flag indicating that autonomous mode is enabled, data is communicated, over the reverse wireless link, at a data rate less than or equal to the autonomous data rate without the base station having to first schedule the mobile station.
