Abstract: Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for use in a wireless network for beam failure recovery (BFR). For example, some embodiments are directed to a user equipment (UE). The UE includes radio front end circuitry and processor circuitry coupled to the radio front end circuitry. The processor circuitry can be configured to receive, using the radio front end circuitry, one or more reference signals. The processor circuitry can be further configured to, in response to determining that a beam failure occurred for the one or more reference signals, determine a contention-free (CF) physical random access channel (PRACH) resource for a beam failure recovery (BFR) request. The processor circuitry can be further configured to transmit, using the radio front circuitry, the BFR request using the determined CF PRACH resource.

Abstract: Systems and methods provide channel state information (CSI) measurement based on measuring a demodulation reference signal (DMRS) for a physical downlink shared channel (PDSCH) transmission. A UE may determine the DMRS for the PDSCH transmission with frequency hopping, and measure the DMRS for the PDSCH transmission to determine a CSI measurement. The UE may then report the CSI measurement to a base station.

Abstract: This disclosure relates to techniques for performing physical uplink shared channel transmissions with improved reliability in a wireless communication system. The wireless device may establish a wireless link with a cellular base station. The wireless device may receive uplink data transmission configuration information from the cellular base station. The uplink data transmission configuration information may configure an uplink data transmission to multiple transmission-reception-points. The wireless device may perform the uplink data transmission to the multiple transmission-reception-points.

Abstract: Systems and methods for using clear channel assessment (CCA) on a channel prior to transmitting the channel are disclosed. A wireless transmission system may perform omnidirectional CCA using a CCA power threshold that is calculated based on a number of synchronization signal blocks (SSBs) transmitted by the wireless transmission system per SSB burst or per synchronization signal/physical broadcast channel (SS/PBCH) block measurement timing configuration (SMTC) window, or on a number of transmit (Tx) antennas used. A wireless transmission system may perform directional CCA on one or more Rx beams that correspond to one or more intended Tx beams using CCA power thresholds calculated based on an equivalent isotropic radiated power (EIRP) of the one or more intended Tx beams to determine directional availability of the channel. A wireless transmission system may determine a CCA power threshold based on a scaling between an actual CCA bandwidth and a nominal CCA bandwidth.

Abstract: This disclosure relates to techniques for configuring, performing, and reporting neighbor cell measurements in a wireless communication system. A base station of a serving cell may provide configuration information relevant to performing layer 1 (L1) measurements based on reference signals of one or more neighbor cells. A UE may perform L1 inter-frequency measurements of the neighbor cell(s) based on the configuration. The UE may report the measurements.

Abstract: A first cellular base station transmits a configuration message to a reporting device installed on a high-speed vehicle. The configuration message specifies one or more parameters of a Doppler measurement report. The reporting device performs one or more first Doppler measurements on the first base station and/or one or more second Doppler measurements on a second base station. The reporting device transmits the Doppler measurement report to the first and/or second base stations. The Doppler measurement report may be used by the first and/or second base stations to perform Doppler pre-compensation on transmissions to the reporting device.

Abstract: A wireless communication system may use higher layer signaling to send transmission configuration indicator (TCI) parameters for a frequency band comprising the 52.6 GHz to 71 GHz range. A DCI message may be used to indicate an enabled TCI state for a channel occupancy time (COT). The wireless communication system may apply the enabled TCI state for the COT as indicated in the DCI message.
