Abstract: This disclosure describes systems, methods, and devices related to reverse direction multi-user multiple input multiple output (MU-MIMO). A device may determine a reverse direction indication to be included in a frame for transmission to one or more first devices in a MU-MIMO communication. The device may cause to wirelessly transmit the frame to a first device of the one or more first devices. The device may identify an acknowledgment frame from the at least one of the first devices based at least in part on the reverse direction indication

Abstract: Techniques for group-based spatial stream assignment signaling in 60 GHz wireless networks are described. According to various such techniques, a 60 GHz-capable transmitting device may be configured to define one or more DL MU-MIMO groups, each of which may comprise one or more respective 60 GHz-capable receiving devices. In various embodiments, the 60 GHz-capable transmitting device may include a DL MU-MIMO group ID within DL MU-MIMO control information in a PHY header of a PPDU in order to indicate that the PPDU is directed to a DL MU-MIMO group corresponding to that DL MU-MIMO group ID. In some embodiments, DL MU-MIMO control information may comprise information specifying spatial stream assignments for the 60 GHz-capable receiving devices of that DL MU-MIMO group. Other embodiments are described and claimed.

Abstract: This disclosure describes systems, methods, and devices related to directional enhanced distributed channel access (EDCA) with interference avoidance. A device may determine a first radio frequency baseband (RF-BB) chain and on a second RF-BB chain associated with one or more antennas of the device. The device may identify a frame from a first device on the first RF-BB chain and the second RF-BB chain. The device may determine the frame is intended for the first RF-BB chain. The device may cause to access a communication channel using the first RF-BB chain. The device may determine an antenna pattern associated with the second RF-BB chain that does not substantially interfere with the first RF-BB chain. The device may cause to access the communication channel using the antenna pattern.

Abstract: Certain embodiments herein are directed to enabling service interoperability functionality for wireless fidelity (WiFi) Direct devices connected to a network via a wireless access point. A WiFi Direct device may identify various other WiFi Direct devices on a WiFi network for performing a requested service, such as printing content or displaying content to a screen. In so doing, the device may share information associated with an access point to which the device is connected with the other devices, which may also share information associated with an access point to which they are connected. In this way, WiFi Direct devices may discover their connectivity with respect to other devices to utilize a broader array of connection options for implementing a desired service, and hence, may leverage application programming interface (API) modules directed at providing service interoperability functionality between software applications and services requested by the software applications.
