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 (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.

Abstract: Some aspects of this disclosure include apparatuses and methods for implementing mechanisms for performing L1-RSRP (Layer 1 Reference Signal Received Power) measurements and/or L1-SINR (Layer 1 Signal-to-Noise and Interference Ratio) measurements on a neighbor cell. For example, some aspects of this disclosure relate to an electronic device. The electronic device includes a transceiver configured to communicate with a serving cell and a neighbor cell and a processor communicatively coupled to the transceiver. The processor determines a measurement period for a Layer 1 (L1) measurement on the neighbor cell and receives, using the transceiver, a resource from the neighbor cell during the measurement period. The processor further performs the L1 measurement on the neighbor cell using the received resource from the neighbor cell.

Abstract: Some embodiments include an apparatus, method, and computer program product for simultaneous multiple secondary cell (SCell) fast activation in a wireless communications system. Some embodiments include a user equipment (UE) that can simultaneously activate multiple SCells. In some embodiments, after receiving an activation command, the UE can receive two or more temporary reference signals (T-RSs) which are user equipment (UE) specific reference signals. The UE can use the T-RSs for fine time/frequency (T/F) tracking and Automatic Gain Control (AGC) adjustment of corresponding SCells resulting in reduced SCell activation latency compared to utilizing a Synchronization Signal (SS)/Physical Broadcast Channel (PBCH) Block Measurement Timing Configuration (SMTC).

Abstract: Some embodiments include a system, method, and computer program product for radio resource management (RRM) scaling factor enhancement without measurement gaps (MGs) in an E-UTRA-New Radio (NR) Dual Connectivity (EN-DC) network. Some embodiments include a user equipment (UE) that receives from a Primary Node (PN), a first NR measurement object (MO) without MG associated with a frequency. The UE receives from a Secondary Node (SN), a second NR MO without MG associated with the same frequency. The UE allocates resources based on a Primary Secondary Component Carrier (PSCC) and determines a scaling factor for determining a total procedure period for obtaining measurements to satisfy the first and the second NR MO without MG. Some embodiments include combining counts of NR MO without MG at a same frequency. Some embodiments include coordination between the PN and the SN so that MOs without MG at a common frequency satisfy the merging rule.
