Abstract: A cellular base station (BS) which determines an aperiodic sounding reference signal (SRS) triggering offset configuration specifying an offset between an aperiodic SRS trigger received by a user equipment (UE) and transmission of the SRS by the UE. The cellular base station may determine that the SRS triggering offset should be adjusted. In response, the cellular base station may transmit signaling to the UE specifying a new value for the aperiodic SRS triggering offset. The new SRS triggering offset value may be partly based on a minimum timing offset for the UE and may be contained in a medium access control (MAC) control element (CE) or in downlink control information (DCI). Additionally, the new triggering offset value may be applicable for a plurality of component carriers or bandwidth parts. The cellular base station may also determine a new triggering offset value due to conflicts regarding the AP-SRS transmission.

Abstract: The present application relates to devices and components including apparatus, systems, and methods to configure a UE for dual connectivity. In an example, a network node requests the UE to indicate the capability it supports for the dual connectivity. This request can implicitly or explicitly indicate that the UE should report carrier grouping information. In response, this information is sent by the UE, and the network node can configure an MCG and an SCG for the UE based on the reported carrier grouping information.

Abstract: Systems, methods, and circuitries are provided for quantizing artificial intelligence (AI)-based compressed channel state information (CSI) feedback. In one example, a method includes receiving a set of encoder outputs from an AI-based encoder that generates compressed CSI feedback. The method includes optimizing a per-segment vector quantization (VQ) codebook for use in quantizing respective segments of encoder outputs based on the set of encoder outputs. A number of inputs of the VQ codebook and a number of outputs of the VQ codebook are based on a number of bits configured for uplink channel information (UCI) and a number of segments.

Abstract: Techniques discussed herein can facilitate one or more enhancements to beam management for a User Equipment (UE) operating in a Discontinuous Reception (DRX) mode. A first set of techniques relates to enhancements to transmission of Scheduling Request(s) (SR(s)) by UEs operating in DRX mode. A second set of techniques relates to enhancements to beam failure detection and recovery by UEs operating in DRX mode. A third set of techniques relates to enhancements to beam measurement and reporting by UEs operating in DRX mode. Various embodiments can employ one or more techniques of the first set of techniques, the second set of techniques, and/or the third set of techniques.

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: A user equipment (UE) and a network agree on the use of a hybrid automatic repeat request (HARQ) codebook. The UE receives a plurality of downlink control information (DCI) transmissions during a corresponding plurality of physical downlink control channel (PDCCH) monitoring occasions from the base station, wherein each DCI transmission schedules multiple physical downlink shared channel (PDSCH) transmissions on a corresponding one of a plurality of component carriers (CCs), receives a time domain resource allocation (TDRA) table configuration from the base station, determines a maximum number of PDSCH transmissions per CC based on the TDRA table configuration, groups the plurality of CCs together and determines a hybrid automatic repeat request (HARQ)-acknowledgement (ACK) codebook size based on a number of the multiple PDSCH transmissions, the maximum number of PDSCH transmissions, and a resulting ACK or negative acknowledgement (NACK) for each of the multiple PDSCH transmissions.
