  • Patent number: 12232137
    Abstract: A user equipment (UE) is described. The UE includes transmitting circuitry configured to transmit a demodulation reference signal (DMRS) for a physical uplink shared channel (PUSCH). In a case that a number of bits for downlink control information (DCI) used for indicating an index of an uplink antenna port(s) is more than 1 bit, the DMRS for the PUSCH is transmitted using the index of an uplink antenna port(s) indicated by using the DCI used for indicating the index of the uplink antenna port(s). In a case that a number of bits for downlink control information (DCI) used for indicating an index of an uplink antenna port(s) is 0 bit, the DMRS for the PUSCH is transmitted using an index of the uplink antenna port(s) configured by using first information.
