Abstract: Described embodiments improve the performance of a computer network via selectively forwarding packets to bypass quality of service (QoS) processing, avoiding processing delays during critical periods of high demand, increasing throughput and efficiency may be increased by sacrificing a small amount of QoS accuracy. QoS processing may be applied to a subset of packets of a flow or connection, referred to herein as “lazy” processing or lazy byte batching. Packets that bypass QoS processing may be immediately forwarded with the same QoS settings as packets of the flow for which QoS processing is applied, resulting in tremendous overhead savings with only minimal decline in accuracy.

Abstract: This disclosure is directed to reducing connection time in direct wireless interaction. Devices may interact via direct (e.g., device-to-device or “D2D”) wireless communication. As part of connection setup operations, a device may receive an invitation to join an existing wireless group. For example, an invitation message may be received by the device on at least one known beaconing channel. The invitation message received by the device may at least identify an operating channel on which connection establishment operations will commence. Following completion of the connection setup operations, the device may initiate scanning on the operating channel identified by the invitation message to expedite the start of connection establishment operations. After connection establishment operations are complete, the device may be able to interact with at least one other device via direct wireless interaction.

Abstract: Disclosed herein is an operating method of a station (STA) in a wireless LAN (WLAN) system. The method includes receiving a downlink (DL) physical protocol data unit (PPDU) and sending an uplink (UL) PPDU as a response to the DL PPDU. The DL PPDU may include at least one MAC protocol data unit (MPDU) and the at least one MPDU may include a first high efficiency (HE) control field. The UL PPDU may include at least one MAC protocol data unit (MPDU) and the at least one MPDU may include a second high efficiency (HE) control field. The each of the first and second HE control fields corresponds to an HT control field and comprises a plurality of aggregated HE control subfield. The HT control field includes VHT subfield value set to “1” and HE subfield value set to “1”.

Abstract: In an example of multi-user wireless communications, an access point may send a downlink frame, including a common field and a user specific field, to multiple stations. The common field and the user specific field are located in a header field called a high efficiency signal-B (HE SIG-B) field. The common field includes information for all of the stations. The user specific field includes multiple sub-fields. At least one of the multiple sub-fields is for each of the stations. The stations may decode their respective portions of the downlink frame based on the common field and their respective sub-field(s). Some or all of the stations may generate and transmit their respective uplink frames, for multi-user transmission such as OFDMA, based on the common field and their respective sub-field(s) included in the downlink frame. The downlink frame may be a trigger frame. Other methods, apparatus, and computer-readable media are also disclosed.

Abstract: An apparatus may receive, from a scheduling entity, sidelink grant information in a downlink control channel. After receiving the grant information in the downlink control channel, the apparatus may transmit a request-to-send (RTS) signal comprising an indication of a requested duration of time to reserve a sidelink channel for sidelink data. If the sidelink channel is available for the requested duration of time, the apparatus may receive a clear-to-send (CTS) signal configured to indicate an availability of the sidelink channel for the requested duration of time. Subsequently, the apparatus may communicate, with another apparatus different from the scheduling entity, the sidelink data using the sidelink channel during the requested duration of time. Afterwards, the apparatus may communicate acknowledgment information corresponding to the communication of the sidelink signal with the other apparatus. Various additional and alternative aspects are described herein.

Abstract: The proposed technology relates to the issue of supporting release of common radio resources in a radio communication network. A radio network controller sends an indication of a value of a timer for implicit release of common radio resources to a base station. The base station receives the indication of a value of a timer for implicit release of common radio resources and determines whether to release common radio resources based on the indication of a value of the timer for implicit release of common radio resources. In this way, by using the indication of a value of the timer for implicit release the base station will be able to correctly determine whether to release the common resources upon reception of a report of empty buffer status from a UE. This will eliminate misinterpretations of the empty buffer status report, and avoid unnecessary radio link failures.

For each sending of the first synchronization signal, the network node sends an associated information message at a pre-defined time and frequency position in an OFDM symbol. The pre-defined time and frequency position is relative to the time and frequency position of the first synchronization signal. The associated information message is associated with the first synchronization signal.

Abstract: Technical solutions are described for facilitating intra-vehicle wireless communication among a plurality of electronic control units. An example method includes determining, by a first electronic control unit in a vehicle, a wait-time for a message, which is to be transmitted to a second electronic control unit in the vehicle via a wireless channel. The first electronic control unit executes a first availability-check, by determining availability of the wireless channel. In response to the first availability-check indicating that the wireless communication channel is available, the method includes delaying transmission of the message by the wait-time. The method also includes executing, by the first electronic control unit, after passage of the wait-time, a second availability-check. In response to the second availability-check indicating that the wireless communication channel is still available, the method includes transmitting the message for receipt by the second electronic control unit.
