  • Patent number: 11368402
    Abstract: A system and method for soft locking on an ingress port of a networking device in a network, such as a network-on-chip (NoC). Once a soft lock is established, the port is given transmitting priority so long has the port has an available packet or packet parts that can make forward progress in the network. When the soft lock port's packet parts, which can make forward progress in the network, are not available, the networking device may choose another port. The system transmits packet parts from the other port until the soft locked port has packet parts available that can make forward progress in the network. Any arbitration scheme may be used to select the port that is soft locked and to select the other ports to transmit from when the soft locked port does not have packet parts that can make forward progress in the network. Once the packet (or all the packet parts) on the soft locked port has completed transmission, the soft lock of the soft locked port is released.

  • Patent number: 11356171
    Abstract: Methods, systems, and devices for wireless communications are described and may include a user terminal and a satellite establishing a communication link over a channel having a channel delay and a medium access control-control element (MAC-CE) delay being determined based on the channel delay. The user terminal and the satellite may be within a non-terrestrial network (NTN). The user terminal may receive a MAC-CE command that indicates a communication parameter to be implemented or adjusted. The user terminal may transmit feedback, for example, to the satellite in response to the MAC-CE command, and the user terminal and the satellite may communicate according to the communication parameter in the MAC-CE command after an end of the MAC-CE delay.

  • Patent number: 11349769
    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.

  • Patent number: 11343747
    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.

  • Patent number: 11343853
    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.

  • Patent number: 11323169
    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.

  • Patent number: 11290304
    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.

  • Patent number: 11284404
    Abstract: A device and method of avoiding future self-interference are described. During a current predetermined time period, a priori knowledge of an RF environment is used to determine a change in the environment in a next predetermined time period. Transmission on an interfering channel in response to the change leads to generation of an indication to another device to switch communications in the next predetermined time period to a new channel that is unaffected by transmission on the interfering channel. The new channel is set by the indication or is negotiated by the other device from a list of channels to use in the indication.
