Abstract: A method for controlling the flow of data traffic on a destination device in a network involves (a) providing a table associated with the destination device; (b) reading each entry of the table from the start of the table to the end of the table; (c) for each port entry read, determining whether a buffer storage threshold for data received from a source port has been exceeded. When the buffer storage threshold for data received from the source port is determined to have been exceeded, an internal stop message is transmitted to a media access control unit on the destination device, otherwise an internal continue message is transmitted to the media access control unit. Operations (b) and (c) are repeated for each of a plurality of read cycles.
Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for sharing a transmission opportunity (TXOP) of a wireless channel. A first wireless local area network (WLAN) device can win a contention-based procedure to become an owner of the TXOP and determine to use the TXOP as a multi-device transmission opportunity (mTXOP). Although the first WLAN device is the owner of the mTXOP, the first WLAN device may allocate resources from the mTXOP to share with other WLAN devices. During a first portion of the mTXOP, the first WLAN device allocate subordinate transmission opportunities (sub-TXOPs) for use by other WLAN devices during a second portion of the mTXOP. The allocation of sub-TXOPs may be prepared based on fairness considerations, latency considerations, or both. In some implementations, a sub-TXOP may be allocated for a non-WLAN device, such as a wireless wide area network (WWAN) apparatus.

Abstract: A distributing control unit performs provisional switching control processing to a distributing unit when a link in use for first data units is a first link and a candidate link to be used is a second link. For example, the distributing control unit distributes at least one of the data units of the first data units of the data stream to the second link and distributes other data units to the first link. A determining unit determines whether or not a link in use for second data units subsequent to the first data units is to be switched from the first link to the second link based on first and second communication qualities, the first and second communication qualities being based on feedback information. The first and second communication qualities are communication qualities of the other data units and the at least one of the data units, respectively.
Abstract: Certain aspects of the present disclosure are generally directed to techniques for selecting a configuration for communication using vehicle to everything (V2X) type communication protocol. Certain aspects provide a method for wireless communication by a user-equipment (UE). The method generally includes determining one or more parameters corresponding to quality of service (QoS) information for communication of data using a V2X communication protocol, reporting the one or more parameters by transmitting a first message, receiving a second message indicating configuration information corresponding to the communication of the data using the V2X communication protocol, and communication the data based on the configuration information.
Abstract: A spatial multiplexing configuration may enable a user equipment (UE) to spatially multiplex two or more uplink channels of different types for simultaneous transmission. For example, a UE may receive an indication of a spatial multiplexing configuration from a base station. The UE may identify two or more uplink channels for simultaneous transmission on a same component carrier, where each uplink channel may be a different type. In such cases, the UE may spatially multiplex the two or more uplink channels on a same set of time/frequency resources on the component carrier in accordance with the spatial multiplexing configuration. The spatially multiplexed uplink channels may then be simultaneously transmitted by the UE on the set of resources, where the spatially multiplexed uplink channels may be simultaneously sent to the same base station or to different base stations. Additionally, different spatial parameters may be applied to each uplink channel.

Abstract: A network includes a plurality of nodes and a plurality of links communicatively coupling each of the nodes to at least one respective adjacent node via a first communication channel and to another respective adjacent node via a second communication channel. The nodes and links have a braided ring topology. First and second nodes of the plurality of nodes source data, are adjacent nodes, and at least one is a source node. The first node sends a first communication to the second node via a third node that is adjacent the first node and via a fourth node that is adjacent the second node. The second node sends a second communication to the first node via the third node and via the fourth node. At least one of the first and second nodes terminates transmission of the first and second communications when the first and second communications do not match.
Abstract: Sounding reference signal (SRS) carrier switching with short transmission time interval (sTTI)/short processing time (sPT) is discussed. A user equipment (UE) with aggregated communications including multiple time division duplex (TDD) downlink-only configured carriers may be triggered for sounding reference signal (SRS) carrier switching via a downlink control signal. The UE determines whether there are any other signals colliding or that may conflict with its transmission of SRS on a new carrier and resolves any apparent collision or conflict using a combination of signal, timing, or processing configuration prioritization. The SRS may be transmitted when conditions allow the UE to tune to the other carrier and tune back before any higher priority transmissions are scheduled.

Abstract: A method and system for steering bidirectional network traffic to a same service device. Specifically, the disclosed method and system entail the maintaining and synchronization of link aggregation group (LAG) tables tied to a pair of LAG ports instantiated on a network element directly connected to a pair of peer linking service devices. Network traffic (i.e., MAC frames) arriving at the network element, from a first host and intended for a second host (e.g., indicative of a first direction of the network traffic), may be steered towards one of the pair of service devices based on hashing of information included in a received MAC frame in conjunction with the LAG table tied to the LAG port (of the pair of LAG ports) that which received the MAC frame.

Abstract: A system includes participant nodes that unicast a voice stream to a master node and receive a multicast voice stream from the master node. The multicast voice stream may be a mixed voice stream mixing the voice streams of the participants. In this case, each participant performs echo cancellation on the multicast voice stream. Alternatively, the multicast voice stream may be a multiplexed voice stream multiplexing the voice streams of all participants. In this case, each participant de-multiplexes the multicast voice stream and generates a mixed voice stream that does not include that participant. Alternatively, the multicast voice stream received by each participant may be a multiplexed digital voice stream multiplexing multiple mixed streams including one mixed stream that does not include the voice stream of that participant. In this case, each participant de-multiplexes the multicast voice stream to obtain the mixed stream that does not include that participant.
