  • Publication number: 20240155696
    Abstract: A user equipment (UE), baseband processor or other network device (e.g., base station, next generation NodeB, etc.) can operate to configure a hand over (HO) or a primary secondary cell (PSCell) addition based on a channel state information reference signal (CSI-RS) based contention free random access (CFRA) procedure. A CSI-RS rough timing of a CSI-RS position can be determined based on a synchronization signal block (SSB) associated with a CSI-RS or a serving cell timing. A CFRA transmit timing can be determined based on the CSI-RS rough timing or a CSI-RS fine timing that is derived from a timing and frequency (T/F) tracking operation on the CSI-RS. Reference signal receive power (RSRP) measurement(s) can be made on the CSI-RS for performing the CSI-RS based CFRA procedure with transmissions according to the CSI-RS transmit timing of the CSI-RS that satisfies an RSRP threshold.

  • Publication number: 20240155679
    Abstract: A user equipment (UE), a base station (e.g., next generation NodeB (gNB)), or other network component can operate to configure multiple transmission reception point (mTRP) communication for new radio (NR) unlicensed (NR-U) standalone communications in a network. A processor or processing circuitry can acquire or share a channel occupancy time (COT) for a first transmission reception point (TRP). The COT can then be mediated with a UE or a second TRP via an ideal backhaul or an ideal backhaul based on a proximity condition. The COT can be shared between the first and second TRP via X2 signaling over an X2 interface.

  • Publication number: 20240155398
    Abstract: Systems and methods for analyzing a validity of an early measurement report (EMR) measurement result are described herein. A base station may configure a threshold value for EMR result validity and receive, from a user equipment (UE), a first measurement value corresponding to a first time at or before expiration of a timer associated with idle mode or inactive mode measurements. The base station receives, from the UE, a second measurement value corresponding to a second time when a radio resource control (RRC) connection setup or resume procedure starts. The base station then determines, based on a comparison of the threshold value to a difference between the first measurement value and the second measurement value, whether the EMR result is valid.

  • Publication number: 20240155525
    Abstract: Systems, methods, and apparatuses disclosed herein can mitigate interference in a wireless network. These systems, methods, and apparatuses can determine a mode of operation of a base station (BS) within the wireless network. These systems, methods, and apparatuses can select a first time advance (TA) when the BS is operating in a static time division duplex (TDD) mode of operation or a second TA when the BS is operating in a sub-band full duplex (SBFD) mode of operation or a dynamic TDD mode of operation. These systems, methods, and apparatuses can advance signals on an uplink (UL) by the first TA to cause the signals on the UL to be time aligned with other signals from other UEs on the UL at the BS to mitigate inter carrier interference (ICI) at the BS.

  • 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.

  • 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.
