Abstract: An electronic device may receive, from a radio node, a measurement configuration associated with a wireless communication system. In response, the electronic device may perform measurements using narrow beam patterns based at least in part on a network configuration, where the narrow beam patterns are narrower than a wide beam pattern of the electronic device. Furthermore, performing the measurements using the narrow beams pattern may include performing a beam-pattern search up to the network configuration. Then, the electronic device may perform an SCell activation procedure of an SCell with the radio node. Note that the SCell activation procedure may include reporting, to the radio node, CSI of a narrow beam pattern of the SCell that is to be activated, where the narrow beam pattern is narrower than the wide beam pattern of the electronic device, and the narrow beam pattern is based at least in part on the measurements.

Abstract: User equipment performs autonomous time adjustment that includes selecting a Timing Error Limit (i.e. Te_NR) and Maximum Autonomous Time Adjustment Step (i.e. Tq_NR) based on bandwidth (BW) and subcarrier spacing (SCS). In one embodiment, given a certain downlink BW, if the SCS=x(kHz) and the Te_NR of this SCS is N, then the Te_NR of SCS=x/2(kHz) is 2*N. Given a certain downlink BW, if the SCS=x(kHz) and the Te_NR of this SCS is N, then the Te_NR of SCS=2*x(kHz) is N/2. For example, given BW=10 MHz, if the Te_NR of SCS=30kHz is n*Ts_NR (TS_NR is the basic timing unit for NR system), then the Te_NR of SCS=60 kHz is N/2*Ts_NR, and the Te_NR of SCS=15 kHz is 2*N*Ts_NR.

Abstract: Methods and architectures to determine whether carrier aggregation (CA) component carrier signals transmitted or received by a user equipment (UE) device with a primary serving cell (PCell) and one or more secondary serving cells (SCell) exceed a maximum transmission timing difference compare a relative difference of signals derived from subframe boundaries, a subslot transmission time interval (sTTI) boundary or a combination thereof, with a maximum receive timing threshold value. In the uplink, timing advance groups (TAGs) for the PCell and/SCells may be compared by the UE to a maximum transmit timing threshold value. If the maximum thresholds are exceeded, the SCell may be dropped or changed to avoid UE from exceeding its power maximums.

Abstract: Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for delivering UE capability indication to a positioning server in a wireless communication network. A user equipment (UE) or access note (AN) may notify a positioning server of UE capability information associated with positioning measurements so that the positioning server may determine corresponding positioning measurement configurations based on acknowledgement of such UE capability information in terms of the positioning measurement. Embodiments describe UE capability indications to a positioning server that may enable flexible deployment and integration of various types of UEs. Other embodiments may be described and claimed.

Abstract: Systems and methods provide for beam detection in a wireless communication system. An apparatus for a UE may be configured to identify a plurality of CSI-RS resources corresponding to different Tx beams configured for measurement by the UE, measure an L1-RSRP for the plurality of CSI-RS resources, determine a selected Tx beam of the different Tx beams based on measured L1-RSRP values for the plurality of CSI-RS resources, and determine a measurement accuracy of a first L1-RSRP value corresponding to the selected Tx beam based on successful beam detection probability.

Abstract: Apparatuses, systems, and methods for performing multi-TRP transmissions using techniques for reducing wireless device power consumption. A wireless device may select a downlink signal buffering method for a communication slot. The downlink signal buffering method may be selected from a single antenna panel signal buffering method or a multi-antenna panel signal buffering method. One or more beams for which to perform downlink signal buffering for the communication slot may be selected based at least in part on the downlink signal buffering method selected. Downlink signals may be received from one or more cellular base stations during the communication slot using the selected one or more beams. The downlink signals received using the selected one or more beams may be buffered by the wireless device.

Abstract: Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for cell identification (ID) and beam ID detections in new radio (NR). The detections comprise NR primary synchronization signal (PSS)/secondary synchronization signal (SSS) detection, PBCH DMRS detection, SS reference signal received power (RSRP) measurement, and slot/SS burst boundary timing acquiring. Various embodiments describe how to detect a cell ID and a beam ID in millimeter wave (mmWave) operation. Other embodiments describe further details regarding how to detect NR cell and beam ID during intra-frequency measurements.

Abstract: An embodiment for user equipment that receives a plurality of measurement gap repetition patterns from a network. Each measurement gap repetition pattern may be assigned to a different frequency of the network. The plurality of measurement gap repetition patterns may include skipping measurement patterns. Further embodiments may include the user equipment receiving a repetition period in a measurement object frame or receiving a plurality of measurement gap repetition patterns in which the measurement gaps are non-colliding with measurement gaps of other repetition patterns assigned to the user equipment.
