Abstract

Various embodiments of the present disclosure provide a method for coordinating resources between different operating networks. The method comprises determining whether coordination with a second operating network is triggered and transmitting a coordination request to the second operating network, in response to determining that the coordination is triggered. The method also comprises receiving a coordination response from the second operating network. The method further comprises determining blanking patterns by initiating a coordination procedure between the first and second operating networks to, in response to receiving an acknowledgement in the coordination response from the second operating network; and scheduling according to one of the determined blanking patterns in the first operating network.

First claim

What is claimed is:

1. A method in a first operating network for coordinating resources between the first operating network and a second operating network, the method comprising:
determining whether coordination with the second operating network is triggered;
transmitting a coordination request to the second operating network, in response to determining that the coordination is triggered;
receiving a coordination response from the second operating network;
determining at least two blanking patterns by initiating a coordination procedure between the first and second operating networks, in response to receiving an acknowledgement in the coordination response from the second operating network; and
scheduling according to a first blanking pattern of the at least two determined blanking patterns, in the first operating network.

2. The method according to claim 1 , wherein:
a second blanking pattern of the at least two determined blanking patterns is used in the second operating network for scheduling, and
the second blanking pattern is different from the first blanking pattern.

3. The method according to claim 1 , wherein said scheduling according to the first blanking pattern of the at least two determined blanking patterns comprises one of:
scheduling, according to the first blanking pattern, all links in the first operating network;
scheduling, according to the first blanking pattern, all links belonging to one or more access nodes in the first operating network that cause interference to the second operating network; or
scheduling, according to the first blanking pattern, one or more links in the first operating network that cause interference to the second operating network.

4. The method according to claim 1 , wherein the coordination with the second operating network is triggered periodically or by detection of new interference from the second operating network.

5. The method according to claim 1 , wherein the coordination procedure comprises blanking ratio coordination and blanking position coordination between the first and second operating networks.

6. The method according to claim 5 , wherein the blanking ratio coordination comprises averaging two blanking ratios proposed by the first and second operating networks respectively, as a coordinated blanking ratio for the at least two determined blanking patterns.

7. The method according to claim 5 , wherein the blanking position coordination comprises:
selecting from a plurality of predefined blanking patterns two different blanking patterns according to a blanking ratio obtained from the blanking ratio coordination; and
signaling the selected two different blanking patterns to the second operating network.

8. An apparatus in a first operating network for coordinating resources between the first operating network and a second operating network, the apparatus comprising:
a processor configured to:
determine whether coordination with the second operating network is triggered;
determine at least two blanking patterns by initiating a coordination procedure between the first and second operating networks, in response to receiving an acknowledgement in a coordination response from the second operating network; and
perform scheduling, according to a first blanking pattern of the at least two determined blanking patterns, in the first operating network, a transmitter coupled to the processor, wherein the transmitter is configured to:
transmit a coordination request to the second operating network, in response to a determination that the coordination is triggered, and

a receiver coupled to the processor, wherein the receiver is configured to:
receive the coordination response from the second operating network.

9. The apparatus according to claim 8 , wherein:
a second blanking pattern of the at least two determined blanking patterns is used in the second operating network for scheduling, and
the second blanking pattern is different from the first blanking pattern.

10. The apparatus according to claim 8 , wherein the processor is configured to perform one of:
scheduling, according to the first blanking pattern, all links in the first operating network;
scheduling, according to the first blanking pattern, all links belonging to one or more access nodes in the first operating network that cause interference to the second operating network; or
scheduling, according to the first blanking pattern, one or more links in the first operating network that cause interference to the second operating network.

11. The apparatus according to claim 8 , wherein the coordination procedure comprises blanking ratio coordination and blanking position coordination between the first and second operating networks.

12. The apparatus according to claim 11 , wherein the processor is further configured to average two blanking ratios proposed by the first and second operating networks respectively, as a coordinated blanking ratio for the at least two determined blanking patterns.

13. The apparatus according to claim 11 , wherein the processor is further configured to select, from a plurality of predefined blanking patterns two different blanking patterns according to a blanking ratio obtained from the blanking ratio coordination and wherein the transmitter is further configured to signal the selected two different blanking patterns to the second operating network.

14. An apparatus in a first operating network for coordinating resources between the first operating network and a second operating network, comprising a processor and a memory, said memory containing instructions executable by said processor wherein said apparatus is operative to:
determine whether coordination with the second operating network is triggered;
transmit a coordination request to the second operating network, in response to a determination that the coordination is triggered;
receive a coordination response from the second operating network;
determine at least two blanking patterns by initiating a coordination procedure between the first and second operating networks, in response to receiving an acknowledgement in the coordination response from the second operating network; and
schedule, according to a first blanking pattern of the at least two determined blanking patterns, in the first operating network.
