  • Patent number: 11877321
    Abstract: A multi-link device (MLD) monitors each of first and second links in a multi-link operation in wireless communications, with the first link being a primary link and the second link being a secondary link. The MLD obtains a transmission opportunity (TXOP) on one of the first link and the second link as a result of performing a contention-based channel access on the first link and the second link. The MLD checks channel status of the other of the first link and the second link. The MLD then transmits one or more frames on the first link but not on the second link, on the second link but not on the first link, or on both the first link and the second link synchronously, responsive to the channel status of the other link given the TXOP being obtained on the one of the first link and the second link.

  • Publication number: 20240015623
    Abstract: A method can include determining an initial beam configuration by a controller at a satellite in a non-terrestrial network (NTN); applying the initial beam configuration to control an antenna array to transmit a beam to cover a target service area; determining subsequent beam configurations, by the controller, corresponding to a sequence of locations along an orbit of the satellite; and applying the subsequent beam configurations at each of the sequence of locations successively to control the antenna array to transmit respective beams to cover the target service area while the satellite is flying along the orbit. The controller determines the initial beam configuration and the subsequent beam configurations in a way that a variation of beam footprints of the beams is minimized to realize a constant beam footprint corresponding to the target service area.

  • Patent number: 11870726
    Abstract: User equipment (UE) for sounding reference signal (SRS) triggering is provided. The UE may include a radio frequency (RF) signal processing device and a processor. The RF signal processing device receives first slot offset information and second slot offset information from a network node. The first slot offset information is configured through a radio resource control (RRC) information element (IE) to indicate a first time difference between the down link control information (DCI) and a resource reference slot. The second slot offset information indicates the second time difference between the reference slot and an SRS resource. The processor is coupled to the RF signal processing device. When the RF signal processing device receives the DCI, the processor triggers an SRS transmission for the SRS resource according to the first slot offset information and the second slot offset information.
