Abstract
Methods and nodes in a cellular communication system for supporting Random Access. A method in a first network node involves determining at least one uplink radio resource amongst a plurality of radio resources, and refraining from scheduling uplink communication in the at least one uplink radio resource, thus enabling a UE in an area with an uplink/downlink imbalance to perform Random Access to a neighbor second network node (B).

A method in a network node in a cellular communication system for supporting random access, the method comprising:
- determining at least one uplink radio resource amongst a plurality of radio resources;
- refraining from scheduling uplink communication in the at least one uplink radio resource, thus leaving the at least one uplink radio resource unscheduled, and thus enabling a user equipment in an area with an uplink/downlink imbalance to perform random access to a neighbor second network node.
A network node in a cellular communication system supporting random access, the network node comprising:
- a determining circuit, adapted to determine at least one uplink radio resource amongst a plurality of radio resources;
- a control circuit, adapted to control uplink scheduling, such that the at least one uplink radio resource is left unscheduled, thus enabling a UE in an area with an uplink/downlink imbalance to perform random access to a neighbor second network node.
A method in a network node in a cellular communication system for supporting random access, the method comprising:
- determining one or more uplink radio resources systematically left unscheduled by a neighbor first network node;
- configuring random access opportunities at at least some of said one or more determined uplink radio resources;
- thus enabling a user equipment in an area with an uplink/downlink imbalance to perform random access to the network node.
