    Abstract: Methods and systems provide implementations for distributed MIMO communication. In one aspect, a method includes receiving a network message including data indicative of user data for transmission by a first access point to a first station over the wireless network prior to the transmission, generating precoded second data for transmission to the first station based on the data indicative of the user data, and transmitting, the precoded data to a third device. In some aspects, the precode data is transmitted by a second access point of a basic service set different than that of the first station to the first station as part of a distributed MIMO communication. In some other aspects, the precoded data is transmitted by a cluster controller to another access point having a basic service set different than that of the first station. The other access point may then transmit a signal based on the precode data to the first station simultaneously with the fist access point also transmitting to the first station. The two transmissions may form a portion of a distributed MIMO communication.

    Abstract: Aspects of the present disclosure provide techniques for efficient ranging, for example, in a neighbor aware network (NAN). According to certain aspects, an apparatus for wireless communications is provided. The apparatus generally includes a processing system configured to determine a period that at least one second apparatus is scheduled to be awake, generate a first frame for transmission to the second apparatus during the period, determine ranging information based on a time difference between transmission of the first frame and receipt of a second frame in response to the first frame, and generate a third frame including the ranging information; a transmit interface configured to output the first and third frames for transmission; and a receive interface configured to obtain the second frame. By exchanging ranging information in already scheduled wake-up periods and in existing frame, power consumption and signaling overhead may be reduced.

    Abstract: An 802.11ac access point (AP) may be capable of communicating with both 802.11n (on 40 MHz band) and 802.11ac devices (on 80 MHz band). While the 802.11ac AP is communicated with 802.11n devices on 40 MHz band, the remaining 40 MHz band is wasted because the 802.11n devices are not capable of communicating on this band. The AP may operate as if it is two virtual APs, one capable of communicating with 802.11n devices on a first primary and a first secondary channels (basic service set 1—BSS1) and the second communicating with 802.11ac devices on a second primary and a second secondary channels (BSS2). Individual beacons may be sent for BSS1 and BSS2. The transmissions on BSS2 may be performed simultaneously with transmissions on BSS1. However, transmission on one channel and receiving on the second channel cannot happen simultaneously.

    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. In one aspect, an apparatus includes a processor configured to send a request to at least one station associated with the apparatus to scan for information related to at least one neighboring access point (AP) operating in a neighborhood of the apparatus and report the information to the apparatus, receive from the at least one associated station a report including the information, generate a neighborhood report related to the at least one neighboring AP, the neighborhood report including the information received from the at least one associated station, and transmit the neighborhood report to one or more other stations not associated with the apparatus to facilitate discovery of an AP of interest to the one or more other stations.
