  • Patent number: 11882516
    Abstract: Cell detection information, such as cell identity, frequency, dormant/active mode, etc. may be determined. This cell detection information may be reported based on properties of a received Auxiliary Synchronization Signal (AuSS) or discovery signal. The received signal may be processed as a function of its timing, for example, with respect to timing of a serving cell. A WTRU may obtain cell detection information for a neighbor cell. A cell may also be detected by surrounding WTRUs. A WTRU may determine timing of cell reactivation from a detected property of the AuSS or discovery signal. A WTRU may trigger an RRC procedure upon selecting a dormant but temporarily reactivated cell. An eNB may transmit AuSS for a dormant cell based on detection of signals received from neighbor cells. Quasi-colocation (QCL) demodulation may be performed based on the detected signal. The on/off state of a cell may be indicated.

  • 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.

  • Patent number: 11876667
    Abstract: A method includes determining that data out of a peripheral device has been interrupted. In response, control signals are transmitted that cause power to not be supplied to the peripheral device and then cause power to be supplied to the peripheral device. If the peripheral device is determined to not be outputting data, whether data into the peripheral device has been restored is determined. If it is not, control signals are transmitted that cause power to not be supplied to a router and then cause power to be supplied to the router. If the router is determined to be outputting data, control signals are transmitted that cause power to not be supplied to a wireless access point that is coupled to the modem and then cause power to be supplied to the wireless access point. Whether the wireless access point is outputting data is determined.
