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 user equipment (UE) may increase the reliability of transmission of a Physical Uplink Control Channel (PUCCH) by transmitting repeated copies of the PUCCH, according to a repetition pattern spanning one or more slots. In an intra-slot mode, more than one copy may be transmitted within each configured slot, with or without frequency hopping. The number of copies as well as a temporal gap between the transmission of successive copies may be configured by the network. The repetition pattern may or may not be interrupted by slot boundaries. In an inter-slot mode, one copy is transmitted per configured slot. Different copies may be transmitted in different directions, according to a spatial consistency pattern. The UE may perform repeated transmission of PUCCHs to different Transmission-Reception Points (TRPs) using respectively different timing advances and/or transmit power levels.

Abstract: The present application relates to devices and components including apparatus, systems, and methods to perform a switch of a TCI state from a serving cell to a neighbor cell. A UE determines whether the state of the neighbor cell is known or unknown and whether the neighbor cell's TCI state is known or unknown. The total delay time to perform the TCI state switch can impacted by this the known/unknown statuses. Other factors can also contribute to the total delay time. The UE may also signal its capability to monitor the TCI state of the neighbor cell and its capability to switch to such a TCI state.

Abstract: This disclosure relates to techniques for performing beam failure recovery and receiving control information with improved reliability in a wireless communication system. The techniques may include the use of multiple beams in conjunction with performing beam failure recovery, for example including identifying multiple candidate beams for beam failure recovery. The techniques may also or alternatively include the use of multiple beams to provide repetitions of control information for search space and control resource set index 0.

Abstract: Methods and systems to activate beams for beam switching based on measurements of a downlink reference signal that is QCL Type-D with a downlink pathloss reference signal are disclosed. A UE may measure and report to a base station the RSRP of the reference signal that is QCL Type-D with a target downlink pathloss reference signal. Based on the reported RSRP measurements, the base station may activate the target pathloss reference signal to command the UE to update the pathloss measurements of the target pathloss reference signal for uplink power control of a beam corresponding to the target pathloss reference signal. The UE may determine whether the target pathloss reference signal is considered known for uplink power control based on the timing relationship among the reception of the reference signal from the base station, the transmission of the RSRP measurement of the reference signal, and reception of the activation command.
