Abstract
A user equipment (UE) receives UE group information indicating a first UE group to which the UE belongs, and transmits uplink (UL) data and a demodulation reference signal (DM-RS), which is for demodulating the UL data, on the basis of the UE group information. The DM-RS is transmitted by means of a first uplink demodulation reference signal (UL DM-RS) resource, which corresponds to the first UE group to which the UE belongs, among a plurality of UL DM-RS resources respectively corresponding to one or more UE groups.
Claims7
A method of transmitting an uplink (UL) signal by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving UE group information on a first UE group to which the UE belongs;
- and
- transmitting UL data and a demodulation reference signal (DM-RS) for demodulating the UL data based on the UE group information,
- wherein the DM-RS is transmitted based on a first UL DM-RS resource related to the first UE group to which the UE belongs among a plurality of UL DM-RS resources respectively related to one or more UE groups,
- wherein transmission power used for each of the one or more UE groups is differently configured based on priority of the each of the one or more UE groups,
- wherein a power offset used for the each of the one or more UE groups is differently configured for the each of the one or more UE groups,
- and wherein a first transmission power used for the UL data is determined based on a first power offset configured to the first UE group to which the UE belongs.
A user equipment (UE) for transmitting an uplink (UL) signal in a wireless communication system, the UE comprising,
- a radio frequency (RF) unit, and
- a processor configured to control the RF unit, the processor configured to:
- control the RF unit to receive UE group information on a first UE group to which the UE belongs;
- and
- control the RF unit to transmit UL data and a demodulation reference signal (DM-RS) for demodulating the UL data based on the UE group information, and
- wherein the processor is configured to control the RF unit to transmit the DM-RS based on a first UL DM RS resource related to the first UE group to which the UE belongs among a plurality of UL DM-RS resources respectively related to one or more UE groups,
- wherein transmission power used for each of the one or more UE groups is differently configured based on priority of the each of the one or more UE groups,
- wherein a power offset used for the each of the one or more UE groups is differently configured for the each of the one or more UE groups,
- and wherein a first transmission power used for the UL data is determined based on a first power offset configured to the first UE group to which the UE belongs.
A method of receiving an uplink (UL) signal from a user equipment (UE) by a base station (BS) in a wireless communication system, the method comprising:
- transmitting UE group information on a first UE group to which the UE belongs;
- and
- receiving UL data and a demodulation reference signal (DM-RS) for demodulating the UL data based on the UE group information,
- wherein the DM-RS is received based on a first UL DM-RS resource related to the first UE group to which the UE belongs among a plurality of UL DM-RS resources respectively related to one or more UE groups,
- wherein transmission power used for each of the one or more UE groups is differently configured based on priority of the each of the one or more UE groups,
- wherein a power offset used for the each of the one or more UE groups is differently configured for the each of the one or more UE groups,
- and wherein a first transmission power used for the UL data is determined based on a first power offset configured to the first UE group to which the UE belongs.
