Abstract: Systems and methods for operating a 5G NR. In particular, a reduced capability (RedCap) user equipment (UE) can be configured to traverse a synchronization raster to locate a cell-defining synchronization signal block (CD-SSB). The CD-SSB can be used to derive, calculate, or otherwise obtain time/frequency information of a non-cell-defining synchronization signal block (NCD-SSB) which may be monitored and/or measured by the RedCap UE in a more power efficient manner.

Abstract: A user equipment (UE) and a network node can support sounding reference signals (SRS) based antenna beam pair selection for simultaneous uplink transmission with multi-panels by the UE. One or more antenna beam pairs of a UE having a first antenna panel and a second antenna panel may be used to transmit SRSs to a first transmission reception point (TRP) and a second TRP simultaneously using SRS resources configured by one or more SRS configuration sets from the network node. The UE can configure a SRS spatial filter for a SRS resource to indicate a direction of an antenna beam, while some of the SRS resource is configured by the one or more SRS configuration sets received from the network node. The network node can select an antenna beam pair among the one or more antenna beam pairs based on indications of signal strength of SRSs received.

Abstract: Embodiments are disclosed for enhanced layer 3 (L3) measurement reporting that supports L3 measurement assisted group-based beam reporting (GBBR). Some embodiments include a user equipment (UE) that can receive a first reference signal from a network at a first angle of arrival (AoA), and receive a second reference signal from the network at a second AoA. The UE can perform L3 measurements on the first reference signal and the second reference signal, and generate and transmit to the network, an enhanced L3 measurement report that includes L3 measurements as well as: a corresponding identity of an antenna panel of the UE; bits that correlate an antenna panel with a respective L3 measurements, or an implication that the L3 measurements in the enhanced L3 measurement report correspond to different antenna panels. The UE can receive simultaneous downlink transmissions from the network that are based on the enhanced L3 measurement report.

Abstract: A user equipment is configured to connect to a base station (BS) over a shared channel subject to channel access operations. The UE receives a first configuration for a BS-initiated fixed frame period (FFP) (BS-FFP) and a second configuration for a UE-initiated FFP (UE-FFP), determines that no downlink (DL) transmissions are detected during a predefined time of the BS-FFP and determines that at least one condition associated with an uplink (UL) transmission is satisfied. When no downlink (DL) transmissions are detected during the predefined time of the BS-FFP and the at least one condition is satisfied, the UE performs a UE-initiated channel access operation. When the UE-initiated channel access operation is successful, the UE performs the UL transmission during the UE-FFP.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for apparatuses and methods for providing continuous communication services for a user equipment (UE) connected to a non-terrestrial network (NTN) and/or one or more satellites providing cellular coverage. The UE may receive a list of neighbor cells from a serving cell, which may be a satellite moving relative to the Earth and having a moving coverage area. After receiving the list of neighbor cells, the UE may sort the list to prioritize the neighbor cells. This sorting may be based on a calculated distance between the UE and each of the neighbor cells. The UE may sequentially perform a synchronization and measurement process with each of the neighbor cells or a subset of the neighbor cells based on the prioritization order. The UE may then establish communications with a target cell from the prioritized list to maintain continuity.

Abstract: A user equipment (UE) may be configured to perform layer 1 (L1) measurement procedures and layer 3 (L3) measurement procedures. The UE configures a channel state information-reference signal (CSI-RS) layer 3 (L3) measurement window, identifies a collision between a layer 1 (L1) measurement operation and a L3 measurement operation and omits at least one L1 measurement in response to identifying the collision.

Abstract: A user equipment (UE) is configured to determine to perform a sounding reference signal (SRS) transmission with an antenna port switch operation, wherein the SRS transmission with the antenna port switch operation is performed during an SRS transmission occasion comprising one or more symbols of a slot and apply one or more scheduling restriction rules corresponding to the SRS transmission with the antenna port switch to provide one or more scheduling restrictions for the UE, wherein the scheduling restrictions cause the UE to omit performing at least one of transmission operations or reception operations during one or more symbols of the slot or one or more symbols of an adjacent slot.

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for relaxing evaluation of radio link quality. According to embodiments of the present disclosure, a terminal device transmits, to a network device, capability information indicating a capability of the terminal device to relax an evaluation of a radio link quality. The terminal device receives, from the network device, a relaxation configuration for relaxing the evaluation. The terminal device performs the evaluation using a relaxed evaluation period determined based on the relaxation configuration. The relaxed evaluation period is longer than a normal evaluation period without relaxing the evaluation.
