  • Patent number: 11411683
    Abstract: Described are methods for interference detection and management in a millimeter wave communications system. A V2X communications system may support interference management procedures that comprise scheduling a system wide training interval in a transmission timeslot, suspending traffic transmissions on a link in the communications system during the training interval to perform training on the link, and resuming traffic transmissions on the link if interference is not detected during the training interval. Interference management procedures may also include receiving at a node, unique parameters transmitted from another node in a communication system during a discovery stage, determining whether interference will occur at the node based on the received unique parameters, and suspending transmissions to and from the node if it is determined interference will occur at the node.

  • Patent number: 11405327
    Abstract: A network device includes a transmit buffer from which data is transmitted to a network, and a packet buffer from which data chunks are transmitted to the transmit buffer in response to read requests. The packet buffer has a maximum read latency from receipt of a read request to transmission of a responsive data chunk, and receives read requests including a read request for a first data chunk of a network packet and a plurality of additional read requests for additional data chunks of the network packet. A latency timer monitors elapsed time from receipt of the first read request, and outputs a latency signal when the elapsed time reaches the first maximum read latency. Transmission logic waits until the elapsed time equals the first maximum read latency, and then transmits the first data chunk from the transmit buffer, without regard to a fill level of the transmit buffer.

  • Patent number: 11398893
    Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may indicate a group of component carriers (CCs) or frequency bands that share quasi co-location (QCL) information. For example, a base station may indicate a set of CCs to a UE. The UE may report, to the base station, a group of CCs, bandwidth parts (BWPs), or both that share a QCL property. For example, the report may include a list of CCs, frequency bands, BWPs, frequency ranges (FRs), or some combination thereof sharing the same QCL property, or the report may indicate whether the CCs in a band share the same QCL property. Based on this report, the base station may activate a transmission configuration indicator (TCI) state at the UE, where the UE may activate the TCI state across the group of CCs, BWPs, or both sharing the same QCL property.

  • Patent number: 11395288
    Abstract: User equipment (UE) can determine a plurality of Downlink Control Information (DCI) formats that correspond to a plurality of transmission modes supported by a base station. When the UE receives a subframe of a radio frame from the base station, it can perform a blind search at the physical layer for a unique identifier associated with the UE in DCI of the subframe using at least one of the plurality of DCI formats. When the UE determines that the unique identifier was found during the blind search using a particular DCI format, it can identify a particular transmission mode that corresponds to the particular DCI format. The UE can then interpret data for the UE in the subframe according to that particular transmission mode.

  • Patent number: 11395335
    Abstract: A wireless transmit/receive unit (WTRU) may perform listen before talk (LBT) on a channel prior to uplink transmission on the channel. The WTRU may adjust an amount of time that the WTRU performs LBT. For example, WTRU may receive a set of transmission opportunities. The WTRU may receive a contention window size (CWS) sequence including a CWS for each transmission opportunity. The CWS sequence may be unique and may be based on the identity of the WTRU. For a given transmission opportunity, the WTRU may select a random number between zero and the CWS for that transmission opportunity. If the channel is clear for at least an amount of time associated with the random number, the WTRU may transmit in the transmission opportunity. If the channel is not clear for at least an amount of time associated with the random number, the WTRU may not transmit in the transmission opportunity.
