Title:
METHOD AND DEVICE FOR UPLINK TRANSMISSION USING EXTENDED UPLINK SUBFRAME
Document Type and Number:
WIPO Patent Application WO/2017/176044
Kind Code:
A1
Abstract:
Provided is an uplink transmission method of a first communication node. When an uplink pilot time slot (UpPTS) of a special subframe and a first uplink (UL) subframe are aggregated as an extended UL subframe, the first communication node receives a reference signal configuration for the UpPTS from a second communication node. Further, when the number of time domain symbols belonging to the UpPTS is equal to or smaller than a predetermined number, the first communication node allocates a reference signal to the first UL subframe among the UpPTS and the first UL subframe on the basis of the reference signal configuration.
