Systems and methods for prioritizing wireless device selection for coordinated multipoint (COMP)
Systems and methods are described for coordinating transmissions from a multiple access nodes in a communication network. A relay-capable status of wireless devices connected to an access node may be determined. Relay capable wireless devices are dynamically selected from the connected wireless devices for assignment of coordinated transmissions from an access node. Scheduling between the selected relay capable wireless devices and the access node is conducted.
1. A method for enabling coordinated transmissions from an access node, the method comprising:
determining a relay-capable status of wireless devices connected to an access node;
prioritizing the relay-capable wireless devices over non-relay capable wireless devices for Coordinated Multipoint (“CoMP”); and
coordinating resource scheduling between the prioritized relay-capable wireless devices and the access node.
2. The method of claim 1 , further comprising:
selecting at least one relay node from the relay-capable wireless devices for prioritized scheduling, the at least one relay supporting a plurality of end-users.
3. The method of claim 2 , wherein the at least one relay node is selected based on a reported RSRP, RSSI, and RF parameter.
4. The method of claim 3 , wherein a radio range of the at least one relay node is configured to expand a coverage area of the access node.
5. The method of claim 4 , wherein resources are scheduled between the at least one relay node and the access node using coordinated scheduling and beamforming CoMP.
6. The method of claim 4 , wherein resources are scheduled between the at least one relay node and the access node using joint processing CoMP.
7. The method of claim 6 , wherein data packets are transmitted to the at least one relay node using a Modulation and Coding Scheme (“MCS”) based on a Channel Quality Indicator (“QCI”) reported by the at least one relay node.
8. The method of claim 6 , wherein data packets are scheduled to the at least one relay node based a load at the relay node and an application profile of the end-users.
9. The method of claim 2 , wherein the at least one relay node is selected based on a loading condition.
10. The method of claim 9 , wherein the loading condition is based on a number of end-users connected to the at least one relay node.
11. A system for enabling coordinated transmissions from an access node, the system comprising:
an network node comprising a processor, the network node configured to:
determine a relay-capable status of wireless devices connected to an access node;
prioritize the relay-capable wireless devices over non-relay capable wireless devices for Coordinated Multipoint (“CoMP”); and
coordinate resource scheduling between the prioritized relay-capable wireless devices and the access node.
12. The system of claim 11 , wherein the network node is further configured to:
select at least one relay node from the relay-capable wireless devices for prioritized scheduling, the at least one relay node supporting a plurality of end-users.
13. The system of claim 12 , wherein the at least one relay node is selected based on a reported RSRP, RSSI, and RF parameter.
14. The system of claim 13 , wherein a radio range of the at least one relay node is configured to expand a coverage area of the access node.
15. The system of claim 14 , wherein resources are scheduled between the at least one relay node and the access node using coordinated scheduling and beamforming CoMP.
16. The system of claim 14 , wherein resources are scheduled between the at least one relay node and the access node using joint processing CoMP.
17. The system of claim 16 , wherein data packets are transmitted to the at least one relay node using a Modulation and Coding Scheme (“MCS”) based on a Channel Quality Indicator (“QCI”) reported by the at least one relay node.
18. The system of claim 16 , wherein data packets are scheduled to the at least one relay node based a load at the relay node and an application profile of the end-users.
19. A method for prioritizing wireless device users for joint processing, the method comprising:
locating multiple relay-capable wireless devices at a coverage hole of a geographic area of a first access node;
selecting, based on a number of end-users, at least one relay-capable wireless device that supports the number of end users; and,
combining a data signal from the at least one relay-capable wireless device at an antenna array of the first access node and a second access node.
