    摘要： A wireless communication device, system and method. The device comprises a memory and processing circuitry coupled to the memory, the memory storing instructions, the processing circuitry to execute the instructions to decode an access point (AP) trigger frame from a coordinator AP including information on respective resource allocations to a plurality of APs (AP resource allocations) for simultaneous downlink (DL) data transmissions to a plurality of wireless stations (scheduled STAs). The processing circuitry is to cause transmission of a wireless frame to a plurality of scheduled STAs associated with the corresponding AP (associated scheduled STAs). The wireless frame includes information on a resource allocation by the coordinator AP to the corresponding AP for the simultaneous DL transmissions, and information on respective resource allocations to the associated scheduled STAs for data transmission from the corresponding AP.

    摘要： Techniques for resource block allocation in a multi-user MIMO High Efficiency WLAN system are provided. Specifically, teachings that when taken alone or together, provide a device or a group of devices with an improved resource allocation for the reduction of usable tone waste, are presented. The present disclosure includes a system that provides a user with a technique allocating data tones prior to the encapsulation unit or overhead tones on a resource block unit. Further, the total allocated bandwidth can be reduced prior resource allocation to overcome modulation and coding scheme downgrading caused by severe puncturing. Alternatively, only band edge basic resource blocks are reduced to account for overhead tones which largely reside on band edges.
