Abstract: A network node, a wireless device and methods therein, for decoding of contention based uplink transmissions of data in a cell served by the network node. The network node registers the wireless device for contention based uplink transmissions of data on a radio resource reserved for contention based uplink transmissions of data. e.g. when receiving a registration request sent from the wireless device, such that the wireless device is included in a set of wireless devices being registered for contention based uplink transmissions of data on the radio resource in the cell. The network node then performs blind decoding of uplink signals transmitted on the radio resource by considering the wireless devices in the set. In this way, the decoding is made more efficient by disregarding any other wireless devices in the cell which are not registered for contention based uplink transmissions of data on the radio resource in the cell.

Abstract: A wireless device is configured with or allocated two or more control resource sets for receiving downlink control information from a base station or cell. The two or more control resource sets correspond to two or more possible states of a time slot used for downlink transmission. The wireless device determines the state of a time slot and selects one or the two or more control channel resource sets to monitor for DCI depending on the state of the time slot. In one exemplary embodiment, the time slot has two possible states and the state of the time slot is determined by the presence or absence of an SS block.

Abstract: One way to increase robustness against beam pair link failure is by transmitting downlink (DL) control signaling (e.g., PDCCH) in more than one beam. That is, one way to mitigate BPLF is for the UE to receive DL control signaling over both a first BPL (e.g., active BPL) and a second BPL (e.g., monitored BPL) but with larger duty cycle for the second BPL compared to the first BPL. For example, the control signaling can be scheduled every slot on the first BPL and scheduled every Nth slot on the second BPL. In this way, in case the first BPL is blocked and the UE cannot decode the control signaling on the first BPL, the UE can receive control signaling transmitted on the second BPL.
