Title:
METHODS AND APPARATUS FOR ENHANCED SPECTRAL EFFICIENCY AND RELIABILITY OF TRANSMISSIONS WITHOUT GRANT
Document Type and Number:
WIPO Patent Application WO/2018/177092
Kind Code:
A1
Abstract:
Methods and devices for enhancing the spectral efficiency and/or reliability of uplink transmission without grant are provided. Uplink transmissions without grant are transmitted by UEs or received by base stations in accordance with resource groups that map initial uplink transmissions without grant and non-zero numbers of re-transmissions without grant to sub-regions of a grant-free region of a time-frequency resource.
