Abstract: A method is performed by a wireless device for performing a random access. In response to a received paging transmission, and when certain conditions are met, the wireless device randomly selects a random access resource from a plurality of available random access resources. The available random access resources may be spread in time, or in frequency, or in time and frequency. The wireless device then transmits a random access signal on the selected random access resource.

Abstract: A wireless communication device includes a receiver arranged to receive radio signals from a radio access network node of the cellular communication system, and a signal detector arranged to detect a first signal and a second signal among the signals received from the access network node.

Abstract: Wake-up signal grouping is based on a paging probability (PP) type rather than a service type to further reduce false paging. This approach enables differentiation between wireless devices with the same service type. Paging probability can be expressed as a function of the wireless devices' traffic profile, DRX, eDRX, or power saving mode (PSM) configuration, paging configuration (number of narrowbands, paging carriers, nB parameter, etc.), and other parameters.

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.
