摘要: The present disclosure provides a method of transmitting and receiving a signal by a user equipment (UE) in a wireless communication system. The method may include: transmitting an uplink (UL) signal including a reference signal (RS) to a base station; measuring a self-interference (SI) signal based on the UL signal; and transmitting a message based on the measured SI signal. The message may include a request for RS change or information about the state of the measured SI signal.

摘要: A method of transmitting and receiving a signal by a user equipment (UE) in a wireless communication system is disclosure. The method includes receiving information related to beam switching from a base station (BS), generating at least one transmission beam pattern based on the information related to the beam switching, transmitting a reference signal by using the at least one transmission beam pattern, measuring a self-interference signal based on the reference signal, transmitting information about the measured self-interference signal to the BS, and receiving beam pattern information based on the measured self-interference signal from the BS. The beam pattern information indicates a beam pattern determined by the BS, and the information related to the beam switching includes information about one of whether beam switching is requested, a beam switching interval, and the number of beam switching candidates.

摘要: A method for receiving broadcast signals, includes receiving the broadcast signals, demodulating the received broadcast signals by an Orthogonal Frequency Division Multiplex (OFDM) scheme, parsing a signal frame from the demodulated broadcast signals, and bit deinterleaving data in the parsed signal frame, wherein the bit deinterleaving includes block deinterleaving the data with each set of a number of bit groups. The number of bit groups is based on modulation type. When the modulation type is Quadrature Phase Shift Keying (QPSK), the number of bit groups is 2. When the modulation type is 16 Quadrature Amplitude Modulation (QAM), the number of bit groups is 4. When the modulation type is 64 Quadrature Amplitude Modulation (QAM), the number of bit groups is 6. When the modulation type is 256 QAM, the number of bit groups is 8. When the modulation type is 1024 QAM, the number of bit groups is 10.

摘要: A method is presented for receiving broadcast signals. The broadcast signals are received. The received broadcast signals are demodulated by an Orthogonal Frequency Division Multiplex (OFDM) scheme. A signal frame is parsed from the demodulated broadcast signals. Data in the parsed signal frame is bit interleaved. The bit deinterleaving includes block deinterleaving the data with each set of a number of bit groups. The number of bit groups is based on modulation type. When the modulation type is 16 Quadrature Amplitude Modulation (QAM), the number of bit groups is 4. The block deinterleaved data is group-wise deinterleaved by a unit of the bit group and parity deinterleaving parity bits of data in the group-wise deinterleaved data. The bit deinterleaved data is decoded.
