Abstract: Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The UE may receive configuration information to configure the UE with a plurality of channel state information reference signal (CSI-RS) resource sets. One of the CSI-RS resource sets may be allocated for beam failure detection (BFD). The UE may determine, based on a sub-carrier spacing (SCS) of a bandwidth part (BWP), a frequency density of the CSI-RS resources in the BWP in terms of a number of resource elements (REs) per resource block (RB). The UE may determine, based on the frequency density of the CSI-RS resources, an evaluation period for CSI-RS based BFD, wherein the evaluation period is longer for higher frequency densities and the evaluation period is shorter for lower frequency densities.

Abstract: Systems, methods, and apparatuses may configure a measurement gap per frequency group and per cell. Measurement time and frequency resources may be associated with a carrier frequency, a cell, or both. Thus, a user equipment (UE) may determine the measurement configuration based on the carrier frequency, cell, or both. The number of synchronization sequences (SS) blocks in an SS burst may be based on the frequency band of the carrier frequency.

Abstract: Beamforming measurement techniques based on PSS/SSS are disclosed. An apparatus of a user equipment (UE) can include processing circuitry configured to decode a configuration message from a source serving cell, the configuration message indicating signal selection criteria for cell measurement reporting. A synchronization signal (SS) burst set associated with one or more transmission/reception points (TRPs) within a neighboring cell is decoded, the SS burst set including a plurality of SS blocks. A cell bcamforming measurement signal associated with the neighboring cell is generated, based on signal measurements of the SS blocks and the signal selection criteria. A radio resource management (RRM) measurement report message is encoded for transmission to the serving cell, the measurement report message including the cell beamforming measurement signal. A handover command message for initiating a handover to the neighboring cell is decoded, the handover command based on the cell beamforming measurement signal.

Abstract: A user equipment (UE) may receive, from a base station (BS) configured to support activation of a secondary cell (SCell), a request to provide a measurement report. In response to the request, the UE may perform one or more measurements on the SCell using one or more reference signals (RSs). Additionally or alternatively, the UE may generate the measurement report based on the one or more measurements and further transmit the measurement report to the BS. In some embodiments, the UE may further determine a pathloss estimation based on the one or more measurements.

Abstract: Disclosed are methods, systems, and computer-readable medium to perform operations including: receiving first signaling information from a first base station (BS), where the first signaling information indicates that a user equipment (UE) device is to determine an index of a first synchronization signal block (SSB) transmitted by a second BS to the UE device on a second component carrier, based on timing information regarding a first component carrier associated with the first BS; determining a first measurement window for measuring one or more characteristics of the first SSB, where the first measurement window is determined based on a first time offset value Δt1 and an expected length of the first SSB and measuring the one or more characteristics of the first SSB on the second carrier during the first measurement window.

Abstract: A network may transmit either beam deployment information or beam number information to a user equipment (UE) carried on a train and configured for operation in the millimeter wave band. The deployment information may include deployment related distance parameters or azimuth angle spread parameters. The beam number information may indicate a number of network beams associated with a current cell. The UE may determine a number of UE receive beams based on deployment information or the network-indicated number of network beams. The UE may transmit feedback to the network, indicating the number of UE receive beams. Alternatively, the network may send a configuration message indicating a first number of UE receive beams to the UE, which the UE may treat as an upper bound or lower bound in its determination of a desired number of UE receive beams. The UE may transmit the desired number to the network.

Abstract: Aspects herein relate to wireless devices, circuits, and methods for determining a PRACH resource mapping comprising a starting symbol position within a reference slot, wherein the starting symbol position is determined based, at least in part, on a subcarrier spacing configuration of PRACH resources of a wireless network that a wireless device is operating on; and using the radio to transmit a RACH preamble and an associated RA-RNTI via the determined PRACH resource mapping. Further aspects herein relate to devices, circuits, and methods for using a modified RA-RNTI for transmission or reception of data over a wireless network, wherein the wireless network has a subcarrier spacing configuration of PRACH resources, wherein a size of the subcarrier spacing configuration of the PRACH resources causes out-of-range RA-RNTI values to be calculated using a legacy RA-RNTI equation in an unmodified form, wherein the range of permissible RA-RNTI values is from 0 to 216−1.

Abstract: A user equipment (UE), or other network component can operate to configure different sets of resources including different sequence lengths for an uplink (UL) transmission via a UL channel. A first length or at least one of different second lengths can be selected to configure the UL transmission based on one or more conditions, which can include a coexisting radio access technology (RAT), a UE capability, an occupied channel bandwidth (OCB), the type of UL transmission or the like. The UL transmission can be based on at least one of: the first or the second sequence length such as for an initial access procedure based on the coexisting RAT and the OCB, for example.

Abstract: The present disclosure relates to devices, apparatuses, and methods for enhanced PHR reporting in support of UE antenna scaling. A wireless device, which comprises at least one antenna array each comprising a plurality of antenna elements may perform antenna scaling by activating or deactivating at least one of the plurality of antenna elements (with corresponding RF chains) of one or more antenna arrays. The wireless device may generate a power headroom (PHR) report based at least on a difference between beamforming gains obtained after the antenna scaling and before the antenna scaling. The wireless device may then send the PHR report to a base station in communication with the wireless device.
