    • 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.
    • 提供了一种系统和方法,用于在第一WiGig PAL发射机和对应的第一WiGig PAL接收机同步时,一次时钟后续的WiGig PAL的至少一个时钟同步过程。 WiGig 60 GHz标准的独特分层结构提供了一种基于各个WiGig PAL之间的关系简化时钟同步过程的机会,WiGig PAL直接位于WiGig MAC和PHY层之上。 基于在第一WiGig PAL发射机/接收机对中利用已经同步的时钟对,辅助的跨PAL /跨层时钟同步的过程提供了使多个WiGig PAL的时钟同步所需的时间量的显着减少,以便于 一个或多个后续WiGig PAL发射机/接收机对的时钟同步。

    • 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.

    • 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.
