A method of scheduling wireless data transmissions between a mobile terminal (701) and a base station using multiple component carrier signals is disclosed. The method comprises the steps of: receiving in the mobile terminal information from the base station indicating available component carriers; detecting in the mobile terminal at least one dynamic parameter indicative of the mobile terminal's current ability to handle component carriers having non-contiguous bandwidths; determining in the mobile terminal in dependence of the at least one dynamic parameter which of the available component carriers to utilize; and transmitting from the mobile terminal to the base station information indicating the component carriers determined to utilize. By doing this the mobile terminal may choose to limit the number of component carriers used in situations where it is disadvantageous, such as situations where the power consumption of supporting multiple component carriers is high or situations where complex hardware is needed.

The present invention is designed so that, in a future radio communication system that accommodates multiple user terminals having different numerologies, these multiple user terminals can transmit UL reference signals properly. According to the present invention, a user terminal receives information related to an uplink (UL) reference signal, and controls transmission of the UL reference signal in a specific period based on the information related to the UL reference signal. In this specific period, UL reference signals of a plurality of user terminals where different numerologies are configured are multiplexed.

A method, apparatus and system for implementing pre-equalization equalizer tap analysis and correlation in a DOCSIS 3.1 network environment. The disclosed principles improve the pre-equalization analysis in the DOCSIS 3.1 environment by filtering out short distance reflections, which is required for the proper grouping and correlation of modems.

The disclosure provides for an apparatus for wireless communications using carrier aggregation comprised of multiple carrier components. The apparatus can include a processor configured to generate one or more instances of a codeword from a data payload. In an aspect, the apparatus also includes a modulator configured to modulate the one or more instances of the codeword onto the multiple carrier components for transmission. In an aspect, the apparatus also includes a resource manager configured to provide the processor with a virtual carrier space comprising a logical carrier having a contiguous bandwidth equivalent to the aggregated bandwidth of the multiple carrier components. In an aspect, the process may be further configured to interleave at least one of the codeword instances across the multiple carrier components. In an aspect, the modulator may be configured to modulate the codeword instance onto the multiple carrier components in accordance to the interleaving.

According to one aspect of the present invention, a terminal has a receiving section that receives configuration information for multiplexing a short uplink control channel having a short time length and a long uplink control channel having a longer time length than the short uplink control channel within a predetermined period, and a control section that decides whether or not to multiplex the short uplink control channel and the long uplink control channel in the predetermined period based on the configuration information. According to one aspect of the present invention, uplink control information can be reported properly even when multiple uplink control channels of varying time lengths are used.

Disclosed are a communication scheme and a system thereof for converging an IoT technology and a 5G communication system for supporting a high data transmission rate beyond that of a 4G system. The disclosure can be applied to intelligent services (for example, services related to a smart home, smart building, smart city, smart car, connected car, health care, digital education, retail business, security, and safety) based on the 5G communication technology and the IoT-related technology. A method of receiving a synchronization signal block (SSB) by a UE in a wireless communication system may include: identifying whether a bandwidth of a cell transmitting an SSB which the UE desires to receive corresponds to a first frequency band (FR); when the bandwidth of the cell corresponds to the first frequency band, receiving the SSB using a single carrier waveform; and acquiring synchronization, based on the received SSB; and acquiring system information.

Physical layer structures and access schemes for use in such networks are described and in particular initial access channel (IACH) structures are proposed. A spectrum efficient downlink (DL) IACH design supports different types of User Equipment (UE) capabilities and different system bandwidths. An IACH includes the synchronization channel (SCH) and broadcast-control channel (BCH). A non-uniform SCH for all system bandwidths is provided, as well as scalable bandwidth BCH depending on system bandwidth. An initial access procedure is provided, as well as an access procedure.

A signal is transmitted at a high speed in a direction opposite to a transmitting direction of a main large-capacity channel. A first transmitting unit transmits a first signal including a clock component to an external device through a transmission path as a differential signal. A second transmitting unit superimposes a second signal including a clock component on the transmission path as an in-phase signal to transmit to the external device. A state notifying unit communicates with the external device through a pair of differential transmission paths included in the transmission path and notifies the external device of a connection state of its own device by a DC bias potential of at least one of the pair of differential transmission paths.
