Methods and nodes for decoding of contention based uplink transmissions
First Claim
1. A method, performed by a network node of a radio network, for decoding contention-based uplink transmissions of data in a cell served by the network node, the method comprising:
- receiving a registration request from a wireless device, requesting registration of the wireless device for contention-based uplink transmissions of data;
determining whether to register the wireless device for contention-based uplink transmissions on a radio resource reserved in the cell for contention-based uplink transmissions;
responsive to determining to register the wireless device, registering the wireless device for contention-based uplink transmissions on the radio resource and sending a registration acknowledgment to the wireless device, indicating the registration and including an identifier to be used by the wireless device when performing contention-based uplink transmissions on the radio resource;
performing blind decoding of contention-based uplink transmissions on the radio resource, wherein the blind decoding considers the identifier of the wireless device along with the identifiers of any further wireless devices that are also registered for contention-based uplink transmissions on the radio resource.

Abstract
A network node (200), a wireless device (202) and methods therein, for decoding of contention based uplink transmissions of data in a cell served by the network node. The network node (200) registers the wireless device (202) 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 (202) is included in a set (200a) of wireless devices being registered for contention based uplink transmissions of data on the radio resource in the cell. The network node (200) 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.
