Title: COORDINATION OF SCHEDULED AND CONTENTION-BASED UPLINK TRANSMISSIONS
Abstract:
A radio device (10) performs uplink transmissions on a first carrier (F1). The uplink transmissions on the first carrier require scheduling by a node (100) of a wireless communication network. Further, the radio device (10) performs uplink transmissions on a second carrier (F2). The uplink transmissions on the second carrier (F2) require that, by a carrier sense operation, the radio device (10) assesses the second carrier (F2) as being unoccupied before proceeding to the uplink transmission on the second carrier (F2). For a certain uplink transmission on the second carrier (F2), the radio device (10) performs the carrier sense operation to assess whether the second carrier (F2) is unoccupied and provides an indication of a result of the carrier sense operation to the node (100) which is responsible for the scheduling.
