Abstract: A first CSI-RS signal is received by user equipment through a first cell, and a second CSI-RS signal is received through a second cell. Respective QCL information can be available to determine a first Rx beam to measure the first CSI-RS signal and a second Rx beam to measure the second CSI-RS signal. In such a case, if the first CSI-RS signal and the second CSI-RS signal are fully overlapped, then the user equipment can i) alternate between measuring the first CSI-RS signal with the first Rx beam and measuring the second CSI-RS signal with the second Rx beam, or ii) measure only the first CSI-RS signal or the second CSI-RS signal. Other embodiments are described and claimed.

Abstract: Methods and apparatus are disclosed for a UE and its serving base station to coordinate the activation and deactivation of measurement gaps for performing positioning measurements by the UE using target positioning reference signals (PRS) during bandwidth part (BWP) switching. The UE may be configured by the serving base station to have dedicated measurement gaps. The UE determines if a legacy measurement gap used for mobility measurements or a scheduled data transmission collides with the dedicated measurement gaps. If there is a collision, the UE performs the mobility measurement using the legacy measurement gap or transmits the scheduled data. If there is no collision, the UE receives the PRS to perform the positioning measurement during the dedicated measurement gaps. In one embodiment, based on the status of the active BWP and the target PRS, the UE or the base station may activate or deactivate measurement gaps for the positioning measurements.

Abstract: Techniques are described relating to hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback using a HARQ-ACK aggregation window. A User Equipment (UE) may receive control information (e.g., downlink control information (DCI) or radio resource control (RRC) signaling) from a base station including HARQ-ACK codebook information. The HARQ-ACK codebook information may include information on a size of a HARQ-ACK aggregation window. The UE may decode physical downlink shared channel (PDSCH) transmissions and encode corresponding HARQ-ACK feedback using the HARQ-ACK aggregation window based on the control signaling.

Abstract: A method and apparatus of a device that determines an occurrence of the DL SPS or the UL CG to determine a periodicity of a packet generation is described. In an exemplary embodiment, the method receives a configuration for a downlink (DL) Semi-Persistent Scheduling (SPS) or an uplink (UL) Configured Grant (CG). The configuration includes an indication of non-integer periodicity of the DL SPS or the UL CG. Additionally, the method determines an occurrence of the DL SPS or the UL CG based on the received configuration for the DL SPS or the UL CG to determine a periodicity of a packet generation. Thereafter, the method transmits or receives data based on the configuration for the DL SPS or the UL CG.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) to transmit an indication of a link failure on a secondary cell. The indication may be transmitted on resources selected based on one or more conditions. One or more priority rules may be used to resolve collisions. The UE may further make an assumption of a beam or beams to use for communications with the secondary cell following the link failure and prior to receiving an indication from the network of a selected beam.

Abstract: Methods and apparatus are described for transmitting uplink control information (UCI) over an OFDMA-based uplink. In some embodiments, UCI symbols are mapped to resource elements (REs) in the time/frequency resource grid to maximize frequency diversity. In some embodiments, UCI is mapped in a manner that takes into account channel estimation performance by mapping UCI symbols to those REs that are closest (in terms of OFDM subcarriers/symbols) to REs that carry reference signals.

Abstract: Apparatuses, systems, and methods for beam reporting to facilitate multiple transmission and reception points, multi-TRPs, transmission schemes. A UE may receive, from a base station a configuration to report a beam quality based on at least one of a first reporting scheme and a second reporting scheme or a configuration of measurement resources for each TRP of a plurality of TRPs. The UE may report the beam quality based on the configuration or L1 measurements for multiple beam pairs and a recommended and/or assumed transmission scheme based on the configured measurement resources. The first reporting scheme may include the UE reporting at least one L1 measurement for multiple beams and the second reporting scheme may include the UE reporting at least one L1 measurement for multiple beam pairs. The recommended and/or assumed transmission scheme may be a non-coherent-joint transmission (NC-JT) transmission scheme and/or a single frequency network (SFN) transmission scheme.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for support mobility in a wireless network for user equipments (UEs) with varying capabilities. A UE can receive a first system information from a serving base station, where the first system information includes a UE capability condition associated with a neighbor base station, and determine whether a UE capability meets the UE capability condition associated with the neighbor base station. When the UE capability condition is met, the UE can determine whether a first measurement of a first reference signal received from the serving base station and a second measurement of a second reference signal received from the neighbor base station satisfy a threshold condition. When the threshold condition is met, the UE can obtain a second system information from the neighbor base station, indicating the UE has performed handover to the neighbor base station.
