  • Patent number: 11979829
    Abstract: A user equipment (UE) may perform sounding reference signal (SRS) switching by transmitting one or more SRS using a plurality of SRS resources of an SRS resource set configured for SRS switching according to a first combination of downlink (DL) and uplink (UL) antenna ports. For UE power saving, the UE may turn off one or more of the DL and UL antenna ports. The UE may then reconfigure the plurality of SRS resources of the SRS resource set for SRS switching according to a second combination of the DL and UL antenna ports. In response to a power saving message from a UE, a base station may generate SRS configuration information to configure an SRS resource set for SRS antenna switching based on a combination of active DL and UL antenna ports at the UE, and send the SRS configuration information to the UE.

  • Patent number: 11979760
    Abstract: A user equipment (UE) monitors a Physical Downlink Control Channel (PDCCH) in multiple component carriers (CC). The UE determines if the UE is operating in carrier aggregation (CA) mode having a first CC in a first frequency band and a second CC in a second frequency band. When the UE is operating in CA with a first CC in the first frequency band and the second CC in the second frequency band, the UE determines a span pattern for PDCCH symbols being received on the first and second CC and selects a PDCCH monitoring type based on, at least, the span pattern. A UE also determines if a first CC and a second CC of a CA combination are collocated and selects a PDCCH monitoring type based on, at least, the determination of whether the first and second CC are collocated.

  • Patent number: 11979911
    Abstract: Current 5G provisions for wireless communications do not allow for the differentiation of channel access by User Equipments (UEs) with different priorities. Approaches are described by which priority access for UEs in a controlled environment using frame based equipment (FBE), and in particular for different UEs or the same UE that has different configured grants. The approaches are particularly helpful for ultra-reliable low-latency communication (URLLC) UEs. In one approach, the UE performs a clear channel assessment (CCA) in an idle period before the fixed frame period (FFP), followed by a channel access priority test. In an alternative approach, the UE performs a channel access priority test before the UE performs a clear channel assessment (CCA) in an idle period before the fixed frame period (FFP).

  • Patent number: 11979354
    Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing designs for configurations of resource elements to carry reference signals for a user equipment (UE). A reference signal can be processed by the UE according to the configuration of resource elements to carry reference signals. The configurations can be determined by the base station, and received from the base station by the UE. The base station determines the configurations based on information or parameters provided by the UE, e.g., a coherence bandwidth of the channel, a coherence time of the channel, a preference associated with channel status information reference signal, or a preference associated with demodulation reference signal for the UE.

  • Publication number: 20240147423
    Abstract: This disclosure provides details of sequence-based WUS design and signaling, also DCI-based WUS design which also serves as scheduling DCI. For sequence-based WUS there are two variants. A first is based on CSI-RS, that is relatively wide band so the sequence occupies wider band compared to SSB transmission. The second is more akin to the Secondary Synchronization Signal (SSS) type of sequence in that it occupies a narrower band over the entire bandwidth.
