摘要： A method is provided for device detection by a base station comprising receiving a plurality of signals over a preamble subframe from an endpoint. The plurality of signals are attempting to access an access group of the preamble subframe. Additionally, the plurality of signals are received on a random access channel using a wireless network. Further, the plurality of signals have a plurality of last gasp messages (LGMs). The method additionally comprises determining an allowable rate of collisions for the plurality of signals and determining an actual rate of collisions for the plurality of signals. The method includes increasing the size of the access group allocated to the plurality of signals having the plurality of LGMs, based on whether the actual rate of collisions exceeds the allowable rate of collisions.

摘要： A method for cooperative data transfer includes establishing a primary wireless connection with a primary access station. The primary wireless connection uses a primary synchronization channel that is transmitted during a first frame of a super frame. The super frame comprises a plurality of frames. The method also includes detecting a secondary synchronization channel generated by an alternate access station during a subsequent frame of the super frame. The method further includes determining whether the detected secondary synchronization channel has a signal strength greater than a threshold signal strength. The method additionally includes receiving permission to begin a cooperative data transfer operation with both the primary access station and the alternate access station.

摘要： Interference levels occurring at one or more stations are mapped, and a reuse pattern is generated, based on the mapped interference levels, including one or more reuse sets of stations capable of sharing a transmission resource. The stations within each reuse set are listed in increasing order based on their respective interference levels, and an additional station is added to a reuse set, as long as the cumulative interference level within the reuse set is below a threshold interference level and the additional station is not already listed in another reuse set. A network schedule is updated based on the reuse pattern to increase bandwidth efficiency in the network.

摘要： Preamble modulation codes in an OFDMA network are assigned to one of at least two groups, one of the groups indicating that codes assigned to the group are for base stations in the network and a different one of the groups indicating that codes assigned to the group are for relay stations in the network. The relay station attempting to enter or re-enter the network receives a signal transmitted from a station in the network and determines whether the station that transmitted the received signal is a base station or a relay station based on the group to which the preamble modulation code of the received signal was assigned.
