The present disclosure relates to a communication method and system for converging a 5th-Generation communication system to support higher data rates beyond a 4th-Generation system with a technology for Internet of Things (IoT). The present disclosure is 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. A method and apparatus for two-dimensional spatial multiplexing transmission using multiple antennas in a wireless communication system is provided. A user equipment receives pieces of antenna configuration information and corresponding channel measurement resources from a base station, and sends channel information with respect to at least one antenna configuration as feedback to the base station. An indicator indicating a composition of the feedback information is transmitted first, and then the composition information and feedback information are transmitted.

A load cell wireless kit as disclosed can include a load cell and a kit component removably attached to an outside of the load cell. Exemplary embodiments are free of cables and a junction box, and can provide a great convenience for use and save power consumption, without affecting normal system functions.

The present invention relates to a wireless access system supporting machine type communication (MTC) and, particularly, to: a method by which an MTC terminal receives a channel state information index and feeds back channel state information on the basis of the channel state information index; and devices for supporting the method. As one aspect of the present invention, the method by which an MTC terminal feeds back channel state information (CSI) in a wireless access system for supporting machine type communication (MTC) can comprise the steps of: receiving an upper layer signal including a CQI index selected from a mother channel quality information (CQI) table; receiving a physical downlink shared channel (PDSCH) repeatedly transmitted on the basis of a modulation scheme and coding rate indicated by the CQI index; measuring CSI for the PDSCH; and feeding back the measured CSI, wherein the mother CQI table is set to include up to a signal to interference plus noise ratio (SINR) area for a maximum coverage enhancement (CE) level supported in a network, and the CQI index can be selected in consideration of a CE level supportable by the MTC terminal.

A slave control device receives a communication signal from a master control device, and controls loads according to the received communication signal. A modulator superimposes the communication signal from the master control device on power source lines, and a demodulator demodulates the communication signal superimposed on the power source lines and supplies the demodulated communication signal to the slave control device. The modulator is provided on power source lines on a battery side, and the demodulator is provided on the power source lines on a load side. The modulator superimposes the communication signal on the power source lines which are on a side closer to the loads with respect to the modulator among the power source lines.

Methods, apparatus, and systems for data communication over a multi-wire, multi-phase interface are disclosed. A method of calibration includes configuring a 3-phase signal to include a high frequency component and a low frequency component during a calibration period, and transmitting a version of the 3-phase signal on each wire of a 3-wire interface. The version of the 3-phase signal transmitted on each wire is out-of-phase with the versions of the 3-phase signal transmitted on each of the other wires of the 3-wire interface. The 3-phase signal may be configured to enable a receiver to determine certain operating parameters of the 3-wire interface.

This disclosure describes methods, apparatus, and systems to increase the transmission data rate in wireless networks, for example, by using one or more Multiple Input Multiple Output (MIMO) and/or channel bonding techniques. In one embodiment, the disclosure describes the use of Golay Sequence Sets (GSS) to define guard intervals (GIs) for single carrier (SC) single channel bonding and multiple input multiple output (MIMO) transmission. In various embodiments, the disclosure describes the design of guard interval sequence for 3 types of guard intervals having lengths that can be classified as short, medium, and long. In another embodiment, the disclosure defines the guard interval for single channel transmission channel bonding and for MIMO transmission.

A first user equipment is configured to mitigate multi-antenna inter-stream interference. A method by the first UE includes determining, based on one or more criteria, a number of multi-antenna streams whose interference can be currently mitigated by the first UE, and transmitting information based on the number of multi-antenna streams to a first network node, to a second network node, and/or to a second UE. A related method by a first network node serving or managing the first UE includes obtaining information based on a number of multi-antenna streams whose interference can be currently mitigated by a first UE at the first UE, and performing one or more radio operational tasks using the information based on the number of multi-antenna streams whose interference can be currently mitigated.

There is provided a method for transmitting/receiving a signal. The method may be performed by a wireless terminal and comprise: transmitting, by the wireless terminal configured with a carrier aggregation, an uplink signal. The carrier aggregation may include a combination of a evolved universal terrestrial radio access (E-UTRA) operating band 46 and one of E-UTRA operation bands 5, 7, 8, 21, 28 and 41. The method may comprise: receiving a downlink signal. If the uplink signal is transmitted through one of E-UTRA operation bands 5, 7, 8, 21, 28 and 41 and if the downlink signal is received through the E-UTRA operating band 46, a predetermined maximum sensitivity degradation (MSD) is applied to receiving reference sensitivity of the downlink signal, thereby successfully receiving the signal.

Techniques to operate circuitry in an integrated circuit are provided. The circuitry may include a receiver circuit and one of the provided techniques includes receiving a data stream at the receiver circuit. The receiver circuit may include a detector circuit that is used to determine the data rate of the received data stream. A controller block in the receiver circuit may accordingly configure a deserializer circuit in the receiver circuit based on the data rate of the received data stream. The circuitry may further include a transmitter circuit for transmitting data streams. The transmitter circuit may be configured during runtime based on the data rate of a data stream that is being transmitted. In some instances, irrespective of the data rate of the data stream being transmitted, a constant reference clock may be used in the transmitter circuit.
