Abstract
In an uplink transmission method of a first communication node, the first communication node receives a reference signal configuration for an UpPTS (uplink pilot time slot) from a second communication node when the UpPTS of a special subframe and a first uplink (UL) subframe are aggregated as an extended UL subframe. Also, the first communication node allocates a reference signal to the first UL subframe of the UpPTS and the first UL subframe based on the reference signal configuration when a number of time domain symbols belonging to the UpPTS is a predetermined number or less.
Claims9
A transmission method of uplink data by a first communication node, the transmission method comprising:
- receiving a demodulation-reference signal (DM-RS) configuration for an uplink pilot time slot (UpPTS) of a special subframe from a second communication node;
- transmitting the uplink data in the UpPTS when a number of time domain symbols belonging to the UpPTS is a predetermined number;
- and
- transmitting a DM-RS for the uplink data transmitted in the UpPTS based on the DM-RS configuration,
- wherein when the DM-RS for the uplink data is transmitted in the UpPTS based on the DM-RS configuration, the DM-RS is allocated to a fourth time domain symbol from a last time domain symbol among the time domain symbols belonging to the UpPTS.
