Document Type and Number:
WIPO Patent Application WO/2017/078185
Kind Code:
A1
Abstract:
A communication method of a mobile station that performs connectionless-based transmission in a wireless communication system may comprise the steps of: determining a PRB and a DMRS cyclic shift value for transmission of a PUSCH; transmitting the PUSCH to a base station on the basis of the determined PRB and DMRS cyclic shift value; randomly redetermining a DMRS cyclic shift value when a negative acknowledgement (NACK) signal for the PUSCH is received from the base station; and retransmitting the PUSCH on the basis of the redetermined DMRS cyclic shift value.
