    摘要： A system and method are provided for triggering re-beamforming in a 60 GHz communication link based on information collected from platform positional sensors associated with one or the other or both of the transmitters/receivers that constitute ends of the communication link. The disclosed systems and methods monitor various positional sensors that may be used to sense translational and rotational movement of at least one of the platforms on which at least one of the transmitters/receivers is mounted. Information provided by the positional sensors is processed to determine whether or not to trigger re-beamforming for link recovery in 60 GHz communication link. Information provided by the sensors may be used in combination with other link operating metrics, such as PER and RSSI, to make an intelligent determination whether to trigger re-beamforming.

    摘要： A system and method are provided to streamline at least a clock synchronization process for subsequent WiGig PALs once clocks in a first WiGig PAL transmitter and a corresponding first WiGig PAL receiver are synchronized. The unique layering structure of the WiGig 60 GHz standard affords an opportunity to streamline the clock synchronization process based on relationships between individual WiGig PALs, and that the WiGig PALs are directly on top of the WiGig MAC and PHY layers. A process for assisted cross-PAL/cross-layer clock synchronization affords significant reductions in an amount of time required to synchronize the clocks of multiple WiGig PALs based on leveraging an already synchronized clock pair in a first WiGig PAL transmitter/receiver pair to facilitate the clock synchronization of one or more subsequent WiGig PAL transmitter/receiver pairs.

    摘要： A system and method are provided to form multiple separate beamformed wireless communication links between a 60 GHz mmWave transmitter and a cooperating 60 GHz mmWave receiver, to transfer not only wireless data communication between the cooperating devices, but also to transmit usable wireless power between the cooperating devices. These systems and methods employ a technology for establishing multiple beamformed wireless communication links between cooperating 60 GHz mmWave communication devices to transfer wireless data communication between the cooperating devices, and separately to transmit usable wireless power between the cooperating devices over separate wireless directional beamformed links between the devices providing efficient and effective wireless power transmission between the devices based on the directionality of the beamformed links. Because 60 GHz mmWave transmissions are highly directional, with beamwidths on the order of 10-20 degrees, power loss based on wasted energy when compared to existing omnidirectional wireless power transmission systems is significantly reduced.

    摘要： A method, a system and a device for indicating and transmitting the preamble are used to solve the problem existing in the prior art, which reduces the resource utilization efficiency due to that the user equipment (UE) sends the preamble to the evolution base station through the physical random access channel (PRACH) selected by itself in the present random access. The method includes: determining the channel signature associated with the PRACH assigned to the terminal side; sending the determined channel signature to the terminal side, and indicating the terminal side to transmit the preamble using the PRACH associated with the channel signature. Adopting said method can improve the resource utilization efficiency.
