Abstract: Example embodiments provide signaling and configuration for model-based channel state information reporting by an apparatus. Instead of reporting a table of indices or quantized values in case of a several hypotheses, coefficients of a model for requested channel state information may be reported. Apparatuses, methods, and computer programs are disclosed.

Abstract: Systems, methods, apparatuses, and computer program products for reporting of feasibility of activated transmission configuration indicator/transmission coordination indication (TCI) states. For example, a user equipment (UE) may determine whether one or more measurements satisfy one or more thresholds for one or more TCI states, and may transmit an indication of whether the one or more measurements satisfy the one or more thresholds. The UE may then deactivate at least one of the one or more activated TCI states, or may activate one or more additional TCI states, based on the indication, and may use one or more of the activated TCI states for a downlink (DL) or uplink (UL) transmission.

Abstract: Systems, apparatuses, and methods of beam reporting for rank enhancement are provided. One method may include defining an enhanced beam reporting criteria for user equipment (UE) beam reporting. The enhanced beam reporting criteria may be used for transmission rank enhancement. The method may also include configuring at least one user 5 equipment (UE) with the enhanced beam reporting criteria, and receiving at least one beam report, from the at least one user equipment (UE), according to the enhanced beam reporting criteria configured to the at least one user equipment (UE).

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: Examples of the disclosure relate to management of Transmission Configuration Indicator (TCI) States. In examples of the disclosure a User Equipment (UE) can be arranged to receive an indication of a plurality of candidate TCI states. The plurality of candidate TCI states comprise at least one TCI state different to the TCI state with which the UE is currently configured. The UE can also be arranged to transmit an indication of a selected TCI state from the plurality of candidate TCI states where the selected TCI state is different to the TCI state with which the UE is currently configured. The indication of the selected TCI state can be transmitted to a gNB or access node. The transmission of the selected TCI state uses one of a hybrid automatic repeat request (HARQ) acknowledgement (ACK) and an ACK transmission.
