Abstract: Systems, methods, and circuitries are provided for performing sidelink communication. An example method includes receiving, via frequency and time resources of a physical sidelink shared channel (PSSCH), from a second UE, a signal encoding a sequence of bits corresponding to sidelink control information (SCI) stage 2; decoding the sequence of bits based on a SCI stage 2 scrambling initialization value (Cinit) to generate SCI stage 2 for a transport block (TB), wherein Cinit is determined based on at least a portion of a physical sidelink control channel (PSCCH) cyclic redundancy check (CRC) code; and receiving the TB from the first UE based on the SCI stage 2.

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: Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for accuracy measurements in UE baseband-demodulation-performance tests in new radio (NR) frequency range 2 (FR2) operations. The accuracy measurements includes, but not limited to, reference signal received power (RSRP) accuracy, reference signal received quality (RSRQ), and signal-to-noise and interference (SINR) accuracy. Various embodiments describe how to measure RSRP/RSRQ/SINR accuracies in an over-the-air (OTA) test environment in NR FR2 operations.

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.

Abstract: A method for a user equipment (UE) may detect Downlink Control Information (DCI) format 2_0. The DCI format 2_0 may comprise an available resource block (RB) set indicator information element (IE) that indicates a state of Listen Before Talk (LBT) sub-bands, and a Channel Occupancy Time (COT) duration indicator IE. The available RB set indicator is set to an unknown state when there is insufficient time to fully prepare the DCI Format 2_0.

Abstract: Methods, systems, and devices for signaling in cast-type indication for a wireless communication system may include receiving, at a first user equipment (UE), a first stage sidelink control information (SCI) format from a second UE, decoding the first stage SCI format, determining a second stage SCI format using the decoded first stage SCI format, decoding the second stage SCI format, and determining a sidelink feedback status using the second stage SCI format. The sidelink feedback status may indicate whether sidelink feedback is enabled or not enabled. Second stage SCI content may include a distance setting associated with a communication range between the first UE and the second UE.

Abstract: A cellular base station (BS) which transmits more flexible downlink control information (DCI) to the UE, and a UE capable of receiving and processing a received DCI message. The DCI message may have a DCI format of 0_1 or 0_2 and further may comprise an UL-SCH set to 0, a CSI request field of all 0s and an SRS request field having a nonzero value. The DCI message may indicate to the UE that the UE should: 1) transmit an aperiodic SRS corresponding to SRS request; and 2) that the UE should not transmit on the PUSCH. The DCI may include existing fields that specify either a slot offset or beam information useable when transmitting the aperiodic SRS. The base station may also generate a DCI message with an SRS trigger that is targeted to a plurality of UEs in a group, or a plurality of groups of UEs, for greater efficiency.
