Devices and methods are disclosed for a physical sidelink control channel (PSCCH) design in new radio (NR). A wireless transmit receive unit (WTRU) for sidelink communication may receive a resource pool identity (ID). Further, the WTRU may determine whether to include information related to demodulation reference signal (DM-RS) density for a sidelink transmission in sidelink control information (SCI) based on the resource pool ID. On a condition that the information related to DM-RS density is to be included in the SCI, the WTRU may transmit the SCI including the information related to DM-RS density. Also, the SCI may be associated with a PSSCH. Accordingly, the WTRU may transmit the sidelink transmission on the PSSCH with one or more DM-RSs at a first DM-RS density based on the information related to DM-RS density.

Systems, apparatuses, and methods for enhancement for amplify-and-forward relay. Instead of merely passing received signal from a source, relay may equalize the received signal based on reference signal contained in the received signal, before amplifying and transmitting the signal to a destination. Compared to amplify-and-forward, equalize-and-forward may compensate the received source signal for various imperfections such as channel distortions and phase errors, using demodulation reference signal and phase tracking reference signal. The relay may apply Fast Fourier Transform (FFT) to equalize the signal in tone domain.

Disclosed is a method of producing an output signal from a signal generator, comprising: determining a driving input to the signal generator, the driving input for driving the signal generator to provide a predetermined output signal, wherein the output signal includes at least one frame, the at least one frame comprising an active period and a dummy period and wherein the active period and dummy period are determined by the driving input. Also disclosed is a method of producing an output signal from a signal generator, comprising: receiving a synchronisation signal; obtaining an input signal for controlling the signal generator to generate an output signal comprising at least one frame wherein the at least one frame comprises at least one active period and at least one dummy period; producing the output signal comprising a series of frames; and, synchronising the output signal with the synchronisation signal by varying a duration of the at least one of the dummy period or active period.

Selection of equalization coefficients to configure a communications link between a receiver in a host system and a transmitter in an optical or electrical communication module is performed by a management entity with access to management registers in the receiver and transmitter. Continuous modification of the selected equalization coefficients is enabled on the communications link after the communications link is established to handle varying operating conditions such as temperature and humidity.

The present invention provides an operation method of an user equipment in relation to CSI-RS in a wireless communication system. Particularly, an operation method performed by a user equipment (UE) according to the present disclosure includes receiving a higher layer signaling including resource configuration information related to an aperiodic transmission of beamformed CSI-RS from a base station (BS); receiving a first DCI format including first control information indicating that there is an aperiodic transmission of the beamformed CSI-RS from the BS; measuring the beamformed CSI-RS based on the received resource configuration information; and reporting a measurement result of the beamformed CSI-RS to the BS.
