  • Publication number: 20220353041
    Abstract: A user equipment (UE) is described. The UE includes receiving circuitry configured to receive a demodulation reference signal (DMRS) for a physical downlink shared channel (PDSCH). In a case that a number of bits for downlink control information (DCI) used for indicating the DMRS sequence initialization is 1 bit, a sequence of the DMRS for the PDSCH is generated based on a value indicated by the DCI used for indicating the DMRS sequence initialization. The value is among a value of a first scrambling identity (ID) and a value of a second scrambling ID. In a case that the number of bits for the DCI used for indicating the DMRS sequence initialization is 0 bit, the sequence of the DMRS for the PDSCH is generated based on a value of a third scrambling ID.

  • Patent number: 11438929
    Abstract: To make a mobile station apparatus efficiently generate a base sequence. In a mobile station apparatus that generates a sequence for a demodulation reference signal on the basis of at least a sequence group number and transmits to a base station apparatus the demodulation reference signal together with a physical uplink shared channel used for transmission of a transport block, the mobile station apparatus receives information indicating a value of a parameter relating to the sequence from the base station apparatus, and determines the sequence group number without using the value of the parameter in a case where the mobile station apparatus performs transmission of the transport block on the physical uplink shared channel as part of a contention based random access procedure.
