Abstract: A base station (1400) in a wireless communication network transmits, to a user equipment (1300) and on a downlink control channel, a trigger signal that triggers the user equipment (1300) to assess a shared channel. The trigger signal also configures the user equipment (1300) with radio resources of an uplink channel with which to report a result of the assessment. The base station receives, on the radio resources of the uplink channel, the report of the result of the assessment performed by the user equipment (1300) and transmits data on the shared downlink channel to the user equipment (1300). The transmitting of the data is based on the result of the assessment performed by the user equipment (1300).

Abstract: The present disclosure relates to methods of transmitting and receiving transmission feedback in a radio network node. More particularly the disclosure pertains to transmitting and receiving messages acknowledging reception and successful decoding of a transport block in a radio network node. The disclosure also relates to a wireless device providing transmission feedback and to a radio network node receiving the transmission feedback. The disclosure proposes a method, performed in a radio network node, of receiving transmission feedback. The method comprises transmitting S1, using a set of transmission properties, a transport block to a receiving wireless device and receiving S2, from the receiving wireless device, an acknowledgement, ACK, confirming reception and successful decoding of the transport block in the receiving wireless device, wherein the ACK defines a decoding margin of the decoding. The disclosure also proposes a corresponding method in a wireless device and corresponding devices as well as a corresponding computer program.
