    Abstract: Methods and apparatus for adjusting transmission power in wireless networks are provided. One aspect of the disclosure provides an apparatus for wireless communication. The apparatus includes a processing system configured to receive a message instructing each of multiple devices to transmit a packet at least partially concurrently with each transmission of the other multiple devices. The processing system is further configured to generate the packet. The packet includes an indicator having a value greater than a time associated with a transmission of the packet. An interface is configured to provide the packet for transmission.

    Abstract: 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.

    Abstract: Methods and apparatus are described for efficiently suppressing transmission of signals from devices which are using a first protocol in order to allow the frequency spectrum being used by devices using the first protocol to be used briefly for communication between devices using an alternative communications protocol. In some embodiments the first protocol is WiFi and the alternative signaling protocol is a non WiFi peer to peer communications protocol. A wireless communications device e.g. a peer to peer wireless communications device generates a signal suppression utility metric (SSUM). The signal suppression utility metric provides an indication of how useful transmitting a transmission suppression signal e.g. a S CTS signal which may be a CTS to self signal will be at a given point in time. The wireless communications device decides whether or not to transmit a transmission suppression signal as a function of the signal suppression utility metric.

    Abstract: Certain aspects of the present disclosure provide techniques for selecting a modulation class coding rate and/or modulation and coding (MCS) scheme for transmission of a response message corresponding to a received message. Different rules may be applied for selecting the MCS scheme depending on whether or not the frame eliciting the response was transmitted as high throughput (HT) or very high throughput (VHT) transmission.

    Abstract: Systems and methods for wireless communication are disclosed. In one aspect, a method includes generating, by an apparatus, a first message comprising a first indicator indicating a number of beacon intervals that each have a window during which one or more devices are permitted to communicate with the apparatus; and transmitting, by the apparatus, the first message.
