Abstract: One embodiment is directed to a method comprising estimating a velocity vector that is experienced by an apparatus; reporting to a network element, NE, the velocity vector; receiving from the NE at least one primary reference signal, RS, which will be experienced during a predicted trajectory, and at least one secondary RS that will potentially be experienced during the predicted trajectory; sending to the NE feedback based on the at least one primary RS and the at least one secondary RS; and sending an update of the velocity vector to the NE.

Abstract: A technique includes selecting, by a user device independently for each of a plurality of sounding reference signal resources, an uplink data channel power control parameter set for an uplink data channel beam pair to be used to adjust a sounding reference signal transmission power for a sounding reference signal beam pair, adjusting, by the user device for each sounding reference signal resource based on a selected uplink data channel power control parameter set, a sounding reference signal transmission power for a sounding reference signal, and transmitting, by the user device, each of a plurality of power-adjusted sounding reference signals via a corresponding sounding reference signal resource and a corresponding sounding reference signal beam pair.

Abstract: Systems, methods, apparatuses, and computer program products for selecting or prioritizing between a physical downlink shared channel (PDSCH) and synchronization signal PBCH block (SSB) reception are provided. One method may include, when outside a SMTC window and when PDSCH resource allocation overlaps with an occupied SSB location, selecting between the PDSCH and SSB reception according to defined rules.

Abstract: A UE determines a PMI, by performing at least the following: determining an intermediate set of vectors from a FD codebook; forming a subset of the intermediate set of vectors; mapping the subset of vectors to a combinatorial indicator; and forming the PMI at least from the combinatorial indicator. The UE sends the PMI toward a wireless network. A base station receives the PMI from the UE. The PMI includes a combinatorial indicator that maps to a subset of vectors from the FD codebook. The base station determines, using at least the received PMI, information from at least the FD codebook to apply to data for transmission toward the UE.

Abstract: A method and apparatus may include configuring, by a base station, a synchronization signal. The synchronization signal may be aligned with a sub carrier spacing grid of a radio access technology. The synchronization signal may be positioned at a frequency location that is the same or about the same as a frequency step of a channel raster. The synchronization signal may be transmitted to a user equipment so that the center of the synchronization signal is transmitted with a frequency offset with respect to the center of the radio-access technology bandwidth.

Abstract: Signaling is received (or transmitted) to configure a UE with multiple transmit beams, each for receiving beam-specific DCI. A beam-specific current DCI is received at the UE (or transmitted from a network) on the transmit beam(s), including information about beam-specific previous DCIs transmitted to the UE on any of the multiple transmit beams within a predefined time window preceding a time unit in which the current DCI was received. Information about the beam-specific previous DCIs is used to determine that at least one of the multiple transmit beams has been blocked. Each of the multiple transmit beams that have been determined to be blocked is reported to (and received by) the network. In response to receiving from the UE a report indicating at least one multiple transmit beams has been blocked, the network reconfigures the UE with a different set of multiple transmit beams each for beam-specific DCI.

Abstract: According to an aspect, there is provided an apparatus. The apparatus causes transmitting, by a terminal device, a first message comprising a capability value set index and a synchronization signal block resource index, SSBRI, or a channel state information reference signal resource index, CRI. The capability value set index is associated with a sounding reference signal, SRS, resource set. The apparatus causes the terminal device to receive a second message defining a transmission configuration indication, TCI, state comprising a quasi co-location, QCL, -TypeD reference signal corresponding to the SSBRI or CRI or being quasi co-located in terms of QCL-TypeD with a reference signal corresponding to the SSBRI or CRI. The apparatus causes the terminal device to active or indicate the TCI state. If the SRS resource set is different from an active SRS resource set, the apparatus applies a pre-defined latency time between application and expected triggering of the SRS resource set.
