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： In at least some embodiments, a wireless networking system is provided. The wireless networking system includes a base-station and a plurality of user devices in communication with the base-station. The base-station selectively assigns each user device to one of a first group and a second group. Also, the base-station selectively assigns each user device to an uplink synchronized state and an uplink non-synchronized state. The base-station allocates a unique reduced identifier to each user device in the uplink synchronized state, but does not allocate unique reduced identifiers to user devices in the non-synchronized state.

摘要： Systems and methods for media access control (MAC) layer bridging of a real communication device to a simulated network are described herein. Some illustrative embodiments include a communication network bridge that includes a processor that executes simulation software that implements a simulated network and further implements a simulated network interface that provides a communication path to the simulated communication network, and a real network interface that provides a communication path to a real communication network. A first media access control (MAC) layer message that conforms to a protocol associated with the real communication network is received by the real network interface from across the real communication network. The first MAC layer message is transformed by a first transformation operation into a second MAC layer message that is forwarded to a physical (PHY) layer of the simulated network interface.

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 system comprises radio circuitry, an access point (AP) feature, and a station (STA) feature. The AP feature causes the radio circuitry to transmit data to a hardware device during a beacon interval. The AP feature is not used to receive data from the hardware device during the beacon interval except to receive data request signals. The STA feature causes the radio circuitry to receive data from the hardware device during the beacon interval. The STA feature is not used to transmit data to the hardware device during the beacon interval except to transmit data request signals. The radio circuitry is in a de-powered state during the beacon interval when the radio circuitry does not transmit or receive data or data request signals.
