    摘要: Certain aspects of the present disclosure relate to a low-overhead method for communicating Channel State Information (CSI) feedback in Very High Throughput (VHT) wireless communications systems. The present disclosure also provides packet formats for Null Data Packet Announcement (NDPA), CSI Poll and CSI feedback. In some cases, the CSI feedback may be too large to be carried in a single Media Access Control (MAC) protocol data unit (MPDU) or a Physical Layer (PHY) protocol data unit (PPDU), and a proposed protocol for CSI feedback segmentation can be then utilized.

    摘要: Certain aspects of the present disclosure provide techniques and apparatus for managing transmit power in a television white space (TVWS) network. By managing transmit power as described herein, medium re-use may be improved in such a network, and unfair usage problems may be alleviated. One example method generally includes receiving, from an apparatus, a message with an indication of a highest transmit power used by the apparatus for transmitting data frames; and determining that the apparatus is a dominant interferer based, at least in part, on the highest transmit power. Another example method generally includes receiving, from an apparatus, a control or management message with a first indication of a first transmit power used by the apparatus for transmitting data frames; and determining that the apparatus is a dominant interferer based, at least in part, on the first transmit power.
