Abstract: A method of determining a modulation coding scheme (MCS) for communications between a communications device and a client station (STA). The communications device determines a first MCS for transmitting data to the STA during a first sounding interval based, at least in part, on channel state information received from the STA upon initiation of the first sounding interval. The device determines a first series of packet error rates (PERs) associated with one or more data transmissions to the STA during the first sounding interval. The device then determines a second MCS for transmitting data to the STA during a second sounding interval based, at least in part, on the first PER in the first series of PERs. Specifically, the second MCS is independent of the remaining PERs in the first series.

Abstract: Methods, systems, apparatuses, and devices are described for continuity of a wireless serial bus (WSB) service across multiple WSB service sessions. A host may perform a discovery process with a device as part of WSB service session establishment. The host may determine an identifier that is unique to the WSB service provided during the first WSB service session and send the unique identifier to the device. If the WSB service session is terminated, the host may establish a second WSB service session with the device using the unique identifier and without performing another discovery process with the device. The WSB service may support universal serial bus (USB) over Wi-Fi services.

Abstract: Methods, systems, and devices are described for wireless communications. More particularly, the described features relate to techniques for adjusting a modulation and coding scheme (MCS) to account for different airtime utilizations (available airtime actually utilized by a device for transmissions) resulting from different MCSs. In one example, a method for wireless communication may involve: determining a media access control (MAC) efficiency for a station of a plurality of stations based at least in part on a real-time multi-user (MU) physical protocol data unit (PPDU) length, a real-time physical layer service data unit (PSDU) length of each of the plurality of stations, and a modulation and coding scheme (MCS) of the station; adjusting a goodput estimate of the station using the MAC efficiency; and, adjusting the MCS of the station using the adjusted goodput estimate.

Abstract: An allocation technique is operable to allocate communication resources in multi-hop networks under the joint consideration of communication requirements and fairness. Embodiments operate to provide allocation of time slot resources in TDMA based multi-hop wireless networks under the joint consideration of QoS and fairness. Embodiments operate with respect to information regarding maximal common slot set flow contention. An iterative process is applied with respect to the information regarding maximal common slot set flow contention to allocate communication resources providing a balance between meeting communication requirements and fairness. According to embodiments, an inter-graph process iteratively selects a maximal common slot set for which resource allocation with respect to various flows is to be performed and an intra-graph process assigns communication resources in the maximal common slot set providing a balancing between meeting communication requirements (e.g., QoS) and providing fairness. Other aspects, embodiments, and features are also claim and described.

Abstract: Systems and methods for selectively enabling multi-user (MU) communications are disclosed. In some implementations, an access point (AP) obtains packets associated with a traffic flow, and obtains at least one of service-level agreement (SLA) parameters associated with the traffic flow, attributes of the traffic flow, or network parameters associated with a basic service set (BSS) that includes the AP. The AP provides an indication of whether the traffic flow is suitable for transmission as a single-user (SU) multiple-input multiple output (MIMO) (SU-MIMO) communication, as an MU-MIMO communication, as an orthogonal frequency division multiple access (OFDMA) communication, or as a partial bandwidth (BW) MU-MIMO communication to a WLAN subsystem of the AP, the indication being based on one or more of the SLA parameters, the traffic flow attributes, or the network parameters. The AP initiates transmission of the one or more packets based on the indication.
