Network node, wireless device and methods therein for managing uplink resources

A method, performed by a wireless device, for managing one or more uplink resources between the wireless device and a wireless communication network, wherein the method comprises:

• receiving, from a first network node comprised in the wireless communication network, resource information about uplink resources available for the wireless device to request for uplink scheduling between the wireless device and the wireless communication network, said resource information associating each one of multiple such uplink resources with one or more downlink reference signals,
• wherein said resource information further associates one or more of the multiple uplink resources with one or more downlink control channels, which downlink control channels is to be monitored by the wireless device for uplink grants, and
• wherein said resource information further associates one or more of the multiple uplink resources with the following:
• synchronization information to be used by the wireless device for synchronized uplink access;
• and
• power control information informing about power control and that associates different power control with different uplink resources;
• receiving at least one of said one or more downlink reference signals;
• and
• selecting, based on the received resource information and the received at least one of said one or more downlink reference signals, at least one of said uplink resources to request for uplink scheduling.

A first network node, configured to be operative in a wireless communication network, for managing one or more uplink resources between a wireless device and the wireless communication network, wherein the first network node comprises:

• a processing circuit;
• and
• a memory operatively coupled to the processing circuit and storing program instructions for execution by the processing circuit, whereby the first network node is configured to:
• compile resource information about uplink resources available for the wireless device to select and request for uplink scheduling between the wireless device and the wireless communication network, said resource information associating each one of multiple such uplink resources with one or more downlink reference signals,
• wherein the first network node is further configured to compile the resource information about uplink resources based on that it has been identified to exist a probability that the wireless device would select uplink resources for uplink scheduling based on said at least some of the one or more downlink reference signals,
• wherein the probability is identified based on position and mobility information corresponding to the wireless device, and
• wherein the first network node is configured to compile the resource information based on quality information, previously received by the first network node from the wireless device, said quality information being information regarding quality associated with said one or more downlink reference signals;
• and
• send the compiled resource information to the wireless device, thereby enabling the wireless device to select, based on the resource information and said one or more downlink reference signals, at least one of said uplink resources to request for uplink scheduling.
