Certain aspects of the present disclosure provide techniques for wireless communications by a mobile repeater. The mobile repeater measures broadcast signals from one or more target cells as the mobile repeater moves through a network. The mobile repeater selects one of the target cells, based on the measuring and side information. The mobile repeater forwards signals between a user equipment (UE) and the selected target cell.

There is provided, an open radio access network distributed unit (O-DU) having an electronic module that performs an FS-8 Radio Access Technology (RAT) functionality.

The disclosure relates to a communication technique for converging Internet of things (IoT) technology with 5th generation (5G) communication systems designed to support a higher data transfer rate beyond 4th generation (4G) systems, and a system therefor. The disclosure may be applied to intelligent services (e.g., smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail business, security and safety-related services, etc.) on the basis of 5G communication technology and IoT-related technology. A terminal operation method related to each universal subscriber identity module (USIM) when dual connectivity is established for a terminal supporting multi-USIM, and an apparatus therefor are provided.

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein disclose methods and systems of how an application function can request the Fifth Generation (5G) core network to perform a specific action, when a network slice quota reaches a maximum limit or when the behavior of the UE(s) falls outside the expected communication behavior.

In user equipment for communicating with a base station in a radio communication system including the base station and the user equipment, the user equipment includes a receiver that measures received power of reference signals associated with a plurality of different identification information items, the reference signals being transmitted from the base station, and that selects a specific reference signal based on a measurement result; and a transmitter that transmits a random access signal including a preamble sequence, the preamble sequence corresponding to the identification information item of the reference signal selected by the receiver.

A method and a wireless transmit/receive unit (WTRU) are disclosed. The WTRU comprises a receiver, a transmitter, and a processor. The WTRU receives a system information block (SIB) including a parameter indicating a number of transmissions for a random access message and a parameter indicating transmission duration information for the random access message. The WTRU transmits a random access preamble and a random access message, wherein the random access message is transmitted for a duration indicated by the parameter indicating transmission duration information for the random access message. The WTRU retransmits the random access message, wherein the random access message is retransmitted a number of times indicated by the parameter indicating the number of transmissions for the random access message and for the duration indicated by the parameter indicating transmission duration information for the random access message.

A wireless device in an unlicensed band receives from a base station a request signal requesting initiation of downlink (DL) transmission. If carrier sensing (CS) is performed and a wireless medium idles, the wireless device transmits to the base station a response signal accepting the initiation of the DL transmission. The CS is performed with respect to a receive (RX) beam direction obtained from the request signal.

The present disclosure relates to a communication technique for fusing, with an IoT technology, a 5G communication system for supporting a higher data transfer rate than a 4G system, and a system therefor. The present disclosure may be applied to intelligent services, such as smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail businesses, security and safety-related services, on the basis of 5G communication technologies and IoT-related technologies. Disclosed is a setting method for an efficient uplink signal transmission of a terminal in a case where a plurality of waveforms are supported to efficiently operate an uplink in a next generation mobile communication.

This application discloses a communication method and apparatus. A terminal device determines a frequency position of a random access resource based on at least one of an initial frequency offset, a random access resource configuration period, an uplink channel bandwidth, a bandwidth of the random access resource, a time period of a random access resource, a time period of the random access resource, and a frequency index of the random access resource that are configured by a network device, and the terminal device sends a random access signal to the network device at the determined frequency position.

An intelligent voice recognition method, voice recognition apparatus and intelligent computing device are disclosed. An intelligent voice recognition method of a voice recognition apparatus according to an embodiment of the present invention detects a voice of a user, receives an authentication request from the user, and performs authentication for the user on the basis of a result of determination of whether authentication for the user has recently been performed and a result of recognition of the voice of the user, thereby reducing a time and the quantity of calculations necessary for user authentication. One or more of the voice recognition apparatus and the intelligent computing device can be associated with artificial intelligence (AI) modules, unmanned aerial vehicle (UAV) robots, augmented reality (AR) devices, virtual reality (VR) devices, 5G service related devices, etc.
