Title:
GRANT-FREE UPLINK TRANSMISSION IN UNLICENSED SPECTRUM
Document Type and Number:
WIPO Patent Application WO/2019/042270
Kind Code:
A1
Abstract:
Methods and devices for grant-free uplink transmission in unlicensed spectrum are provided. A base station (BS) transmits grant-free resource configuration information to one or more electronic devices (EDs). The grant-free resource configuration information is used to configure the ED for GF uplink transmission in unlicensed spectrum. The GF resource configuration information includes GF ED group-specific resource configuration information indicating GF ED group-specific time-frequency (T/F) resources of the unlicensed spectrum for GF uplink transmission. The ED (s) transmit grant-free uplink transmissions over the unlicensed spectrum in accordance with the GF resource configuration information.
