摘要： A communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IOT) are described. Embodiments may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Described aspects include a method of performing a random access procedure for a connected mode handover by a User Equipment (UE). The method includes transmitting a measurement report associated with a target gNB to a source gNB, wherein the UE performs measurement of the target gNB for one of SS blocks and Channel State Information Reference Signal (CSI-RS) as indicated to the UE by the source gNB.

摘要： The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-Generation (4G) communication system such as long term evolution (LTE). A terminal in a wireless communication system is provided. The terminal includes a transceiver, and at least one processor configured to receive, from a base station (BS), a beam failure recovery configuration comprising at least one reference signal for identifying a candidate beam for the beam failure recovery and associated random access (RA) parameters, identify the candidate beam for the beam failure recovery using the at least one reference signal, and perform a physical random access channel (PRACH) using the at least one reference signal and the associated RA parameters on the candidate beam for the beam failure recovery.

摘要： An apparatus for performing a wireless communication includes a communication interface configured to measure uplink (UL) Sounding Reference Signals (SRSs) transmitted from a mobile client device, and at least one processor configured to buffer a number of uplink (UL) SRS measurements derived from UL SRS transmissions of the mobile client device, the number of UL SRS measurements exceeding a threshold, extract features from UL SRS measurements, obtain a machine learning (ML) classifier for determining a category to be used for estimating mobility associated with the mobile client device, and determine the category of the mobile client device by applying the extracted features to the ML classifier. Methods and apparatus extract the features of either a set of power spectrum density measurements or a set of pre-processed frequency domain real and imaginary portions of UL SRS measurements and feed the features to an AI classifier for UE speed estimation.
