Multi-Grant for Listen-Before-Talk Based Uplink Transmission Attempts

摘要

An access node (100) of a wireless communication network controls radio transmissions on a set of radio resources. The access node (100) determines a group of multiple radio devices (11, 12, 13) and grants an uplink transmission attempt on the set of radio resources to each radio device (11, 12, 13) of the group. The uplink transmission attempt is based on a listen-before-talk procedure. The listen-before-talk procedure involves that the radio device (11, 12, 10 13) performs measurements to detect whether the set of radio resources is available and that, in response to detecting that the set of radio resources is available, the radio device (11, 12, 13) performs a radio transmission to the access node on the set of radio resources.
