Abstract:
A user equipment device (UE) comprises physical layer circuitry configured to transmit and receive radio frequency electrical signals with one or more nodes of a radio access network; and processing circuitry. The processing circuitry is configured to receive system information via the network, wherein the system information indicates cell specific priority and frequency priority; identify candidate cells that have a cell specific priority that is higher than a cell priority of the current serving cell, have a frequency priority that is higher than a frequency priority of a current serving frequency, and satisfy a cell suitability criterion; and determine a candidate cell from the identified candidate cells to replace the current serving cell for communicating with the network.
Abstract:
User Equipment (UE), computer readable medium, and method to determine a mobility of the UE are disclosed. The UE may include circuitry configured to determine a plurality of signals from a serving cell. The each signal of the plurality of signals may be one or more of: a reference signal receive power (RSRP), a reference signal receive quality (RSRQ), a received signal strength indicator (RSSI), a signal-to-noise ratio (SNR), a signal-to-interference-ratio (SIR), a signal-to-interference-plus-noise ratio (SINR), and a CQI. The circuitry may be configured to determine a measure for each of a window size of the plurality of signals. Each measure may be a variance of the plurality of signals, a standard deviation of the plurality of signals, a percent confidence interval (CI) of a mean of the measure, and a linear combination of measures. The circuitry may determine whether the UE is stationary based on one or more measures.
Abstract:
Systems and methods for signaling in an increased carrier monitoring wireless communication environment are disclosed herein. In some embodiments, a user equipment (UE) may include control circuitry to configure the UE for increased carrier monitoring; determine, based on a first signal received from a network apparatus, whether a reduced performance group carrier is configured; determine, based on a second signal received from the network apparatus, whether a scaling factor is configured; and in response to a determination that no reduced performance group carrier is configured and a determination that no scaling factor is configured, allow the UE to monitor fewer carriers than required by increased carrier monitoring. Other embodiments may be disclosed and/or claimed.

Embodiments of user equipment (UE) and method for handover enhancement using a scaled time-to-trigger (TTT) and a time-of-stay are generally described herein. In some embodiments, the TTT is scaled based on at least one of a measured reference signal received quality (RSRQ) value of a serving cell and a time-of-stay in the serving cell.

Aspects of filtering coefficient configuration operations are described. Some aspects include a user equipment (UE) decoding a measurement configuration information element (IE) including a measurement quantity parameter, a reference signal (RS)-type filter configuration and at least one filter coefficient. In some aspects, the UE filters at least one of a cell measurement result and a beam measurement result, according to the measurement configuration IE. If the measurement quantity parameter indicates the cell measurement quantity, the UE can filter the cell measurement result according to the RS type filter configuration and the filter coefficient to determine a measurement evaluation input for a measurement reporting operation. If the measurement quantity parameter indicates the beam measurement quantity, the UE can filter the beam measurement result according to the RS type filter configuration and the filter coefficient to determine a beam measurement selection input for a beam measurement selection operation.

5G methods and architectures to determine active SCells and their bandwidth parts (BWP) used in carrier aggregation (CA) are disclosed in which activating a BWP for an active SCell is performed initially according to a default value provided in initial radio resource control (RRC) messaging. After initialization, SCells and the SCell BWPs used by the user equipment (UE) are activated by RRC messaging, downlink control information (DCI) or dedicated medium access control (MAC) control elements (MAC CEs) with the initial BWP used for an activated SCell being a default value provided during initialization.

Abstract:
Briefly, in accordance with one or more embodiments, a user equipment (UE) may enter into an E-UTRAN Routing Area Paging Channel state, and is configured with an E-UTRAN Routing Area and an Anchor identifier to identify an anchor evolved Node B (eNB) for the UE. The UE selects to a new cell without performing a handover procedure, and performs a cell update procedure. The UE also may enter into a Cell Update Connected state, and is configured with an Anchor identifier. The UE selects to a new cell, performs a cell update procedure, performs a buffer request procedure, and performs a cell update procedure to download buffered data and to perform data transmission with the new cell.
Abstract:
A new radio (NR) capable user equipment (UE) to determine whether to skip cellular measurements using s-Measure configuration based on measurements of a synchronization signal (SS) block (SSB) and/or Channel State Information Reference Signal (CSI-RS) using an s-Measure configuration. For example, an s-Measure configuration can include a reference signal received power (RSRP) value and an indicator whether to apply the value to an NR SS block or a CSI-RS. If the value meets or exceeds the measurement for the indicated signal measurement, the s-Measure is satisfied. For example, in an embodiment, the network configures a single s-Measure configuration (e.g., either an NR SS s-Measure configuration or a CSI-RS s-Measure configuration), which when satisfied the UE does not perform further measurements.
