摘要： An approach is described for a user equipment (UE), wherein the UE includes radio front end circuitry and processor circuitry coupled to the radio front end circuitry. The processor circuitry receives a reference signal from a source device via a radio link, wherein the reference signal is one of the synchronization signal block (SSB) signal or channel state information reference signal (CSI-RS). The processor circuitry measures a quality of the reference signal, and measures an evaluation time of the reference signal. The processor circuitry determines a first indicator of the radio link based on the quality of the reference signal, and determine a second indicator of the radio link based on the evaluation time of the reference signal. The processor circuitry then determines a status of a connection of the radio link based on the first indicator and the second indicator of the radio link, and generate a message based the status of the connection. The radio front end circuitry then transmits the message to the source device.

摘要： 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.

摘要： This disclosure provides techniques for activation of a secondary cell by a user equipment (UE) operating in a wireless network. For example, a UE receives a command to activate a secondary cell of the wireless network for wireless communication, and determines whether timing information is known by the UE for the secondary cell. Based on the determination, the UE performs a first secondary cell activation within first time period based on the timing information being known, or performs a second secondary cell activation within a second time period based on the timing information being unknown. After which, the UE wirelessly communicate data over the wireless network using the secondary cell, based on the secondary cell being activated.

摘要： An approach is described for a user equipment (UE) that includes radio front end circuitry and processor circuitry. The front end circuitry receives an indication from a network entity node, wherein the indication is indicative of a first fraction for a first radio resource management (RRM) procedure and a second fraction for a second RRM procedure. The processor circuitry performs a first measurement of the first RRM procedure in a first fraction of a measurement period. The processor circuitry further performs a second measurement of the second RRM procedure in a second evaluation period, wherein the second evaluation period is the second fraction of the measurement period.

摘要： Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for use in a wireless network for radio link monitoring for high speed user equipment (UE). For example, some embodiments are directed to a user equipment (UE) including radio front end circuitry and processor circuitry coupled to the radio front end circuitry. The processor circuitry can be configured to monitor a downlink associated with a cell using a reference signal and estimate a downlink radio link quality associated with the downlink. The processor circuitry can further be configured to compare the estimated downlink radio link quality with a threshold. The processor circuitry can further be configured to trigger an out-of-sync operation in response to the downlink radio link quality being worse than the threshold. The threshold can include a value less than 10%.

摘要： An apparatus of a user equipment (UE) comprises one or more baseband processors to process a bandwidth part (BWP) switching request from a serving cell at slot n, and to perform an active BWP switch to a new BWP on the serving cell at a time no later than slot n+Y, wherein Y is a BWP switching delay. The one or more baseband processors are to accommodate a timing advance (TA) value to determine when to perform the active BWP switch. The apparatus can include a memory to store the BWP switching request.
