Abstract
An evolved Node B creates or updates peer sets from measured performance information received from one or more stations. The measured performance information includes at least one quality metric associated with a downlink signal sent from the evolved Node B to the one or more stations. The evolved Node B determines excluded timeslots and preferred timeslots based on current resource assignments in each timeslot and based on the peer sets, marks potential resources in an uplink portion of a resource allocation map, and allocates one of the potential resources for peer-to-peer communication between a transmitter station and one or more receiver stations.
Claims20
A method in a network node for allocating resources for peer-to-peer communications, the method comprising:
- creating or updating peer sets, in the network node, from measured performance information received from one or more stations, wherein the measured performance information includes at least one quality metric associated with a downlink signal sent from the network node to the one or more stations;
- determining, in the network node, excluded timeslots and preferred timeslots based on current resource assignments in each timeslot and based on the peer sets;
- marking, in the network node, potential resources in a peer-to-peer portion of a resource allocation map;
- and
- allocating, in the network node, one of the potential resources for peer-to-peer communication between a transmitter station and one or more receiver stations.
A node configured to allocate resources for peer-to-peer communications, the node comprising:
- a creating unit configured to create or update peer sets from measured performance information received from one or more stations, wherein the measured performance information includes at least one quality metric associated with a downlink signal sent from a node to the one or more stations;
- a determining unit configured to determine excluded timeslots and preferred timeslots based on current resource assignments in each timeslot and based on the peer sets;
- a marking unit configured to mark potential resources in a peer-to-peer portion of a resource allocation map;
- and
- an allocating unit configured to allocate one of the potential resources for peer-to-peer communication between a transmitter station and one or more receiver stations.
