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.

Abstract: Computer readable media, methods, and apparatuses for centralized channel access for primary and secondary channels are disclosed. An apparatus is disclosed comprising memory and processing circuitry. The processing circuitry is configured to encode a schedule of one or more resource allocations, wherein each resource allocation comprises a type of allocation, a bandwidth, an indication of a channel, a source association identification (AID), a destination AID, an allocation start, and a duration. The type of allocation may be a service period (SP) or a contention-based access period (CBAP). The channel may be an indication of a basic service set (BSS) or a personal BSS (PBSS) primary channel, BSS or PBSS secondary channel, or BSS or PBSS tertiary channel. The processing circuitry may be configured to transmit the schedule to one or more stations identified by the source AID and the destination AID of the one or more resource allocations.

Abstract: Techniques for power saving by remote wireless mobile devices are provided, in particular by stations (STAs) during downlink (DL) multiple-user multiple-input and multiple-output (MU-MIMO) transmissions in an Institute of Electrical and Electronics Engineers (IEEE) 802.11ay network when reverse direction (RD) transmissions are either enabled and not enabled. Various embodiments enable each STA in a group of STAs to determine an order in which the STAs are requested to send a block acknowledgement (BACK) and which STAs will be granted an RD transmission. Further, a duration of each RD transmission is provided to each STA. Based on the provided information, each STA can determine times to enter a power saving mode. Other embodiments are described and claimed.
