METHODS AND ARRANGEMENTS FOR CONTENTION -BASED UPLINK TRANSMISSION IN A WIRELESS COMMUNICATIONS SYSTEM

摘要

The present invention relates to a user equipment and a radio base station, and to related methods of enabling contention-based uplink transmission. The method comprises the steps of determining (210) configuration information for at least one contention-based uplink transmission opportunity, transmitting (220) the configuration information to at least one user equipment, and for each of the at least one contention-based uplink transmission opportunity, transmitting (230) an access control signal to the at least one user equipment, indicating whether contention-based uplink transmission is allowed for the opportunity.
