摘要： Embodiments provide systems and methods to optimize the time when to transmit a silencing frame, and hence, improve the overall network throughput and avoid access point transmission rate fall-back mechanism having an avalanche effect during coexistence of dissimilar wireless network technologies. A receiver comprises at least two dissimilar network technology subsystems, at least one subsystem of which is higher priority than at least another of the dissimilar subsystems. In some embodiments, a receiver is able to transmit a silencing frame during a predetermined transmission window within a lower priority technology network interval. In other embodiments, a receiver calculates a predetermined transmission window, the predetermined transmission window to occur within a lower priority technology network interval, and transmits a silencing frame during the predetermined transmission window. In further embodiments, a receiver is able to calculate a transmission window to occur during a lower priority technology network interval, and transmit a silencing frame during the calculated transmission window.

摘要： A device comprising transceiver logic and control logic coupled to the transceiver logic. The control logic is adapted to use the transceiver logic to broadcast a signal comprising either a Request-to-Send (RTS) signal or a Clear-to-Send-to-Self (CTS2S) signal to a plurality of other devices. The signal is adapted to cause the plurality of other devices to refrain from transmitting data. After at least some of the plurality of other devices have received the signal, the transceiver logic transmits at least part of another signal using beamforming techniques.

摘要： Systems and methods for reduction of handover latencies in wireless communication systems are described herein. Some illustrative embodiments include a wireless mobile communication device that includes a wireless transceiver including a transmitter configured to transmit a first signal synchronized for reception by a first cellular node, and processing logic that couples to the wireless transceiver. Before the wireless transceiver receives a handover command the processing logic causes the transmitter to transmit a second signal for reception by a second cellular node to request allocation of an upload resource for communication with the second cellular node as part of an impending handover.

摘要： A pre-synchronization method in which the source cell chooses a signature for the user equipment (mobile) to use in the target cell for RACH access, and instructs the user equipment to perform RACH access and return to the current cell before a handover command (break command) is issued. This causes parallel execution of the UL synchronization process with the context transfer process among the two base stations.

摘要： A system and method for using reserved resources in coexisting wireless networks. In one embodiment, a wireless apparatus includes a receiver, a network activity monitor, and a network access scheduler. The receiver is configured to identify a received network reservation message that inhibits access to a first wireless network for an interval defined in the reservation message. The network activity monitor is configured to monitor wireless activity on the first wireless network during the interval. The network access scheduler is configured to determine whether the reservation message prevents conflict of the first wireless network with a coexisting wireless network during the interval, and to schedule, based on a determination that the reservation message prevents conflict with the coexisting wireless network, the wireless apparatus to transmit on the first wireless network during the interval to a wireless device other than a wireless device identified in the reservation message.

摘要： A network includes an access point using a first protocol and a station using both the first protocol and a second protocol. The station uses the first protocol before a first threshold and a second protocol after the first threshold. A first duration between the second threshold and the first threshold is at least of sufficient length for the station to receive one data packet from the access point and send an acknowledgment. The station transmits to the access point a current clear-to-send packet at a current time during a current exchange based on success or failure of a previous exchange during which a previous clear-to-send packet was transmitted to the access point at a previous time.
