  • Reporting of multiple component carriers or frequency bands that share quasi co-location information
    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.

  • Data transmissions and HARQ-ACK associated with an unlicensed spectrum
    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.
