Abstract

In systems and methods of reducing wireless communication signaling overhead, it is determined that communication resource request traffic from a plurality of wireless devices in communication with an access node to communicate with a communication network meets a first threshold. One of the plurality of wireless devices is selected to operate as a router wireless device based on a power storage level and an assigned modulation and coding scheme of each of the plurality of wireless devices. At least one of the unselected wireless devices is instructed to communicate with the communication network via the selected router wireless device.

First claim

What is claimed is:

1. A method of reducing wireless communication overhead, comprising:
determining, at an access node, that resource request traffic from a plurality of wireless devices meets a buffer status reporting threshold;
selecting at least one wireless device from the plurality of wireless devices to operate as a first relay node, the at least one wireless device being selected based on:
a power storage level,
an assigned modulation and coding scheme (MCS), and
a capability to receive multiple data streams;

instructing one or more unselected wireless devices to communicate with the access node via the first relay node using a first network protocol;
aggregating, at the first relay node, resource request traffic from the one or more unselected wireless devices in communication with the access node via the first relay node, the first relay node being configured to communicate the aggregated resource request traffic to the access node using the first network protocol; and
when the aggregated resource request traffic from the first relay node meets a first traffic threshold, instructing at least one second wireless device from the plurality wireless devices to operate as a second relay node.

2. The method of claim 1 , further comprising:
selecting the one or more unselected wireless devices from the plurality of wireless devices based on at least one of an application requirement and a service quality requirement of an application running on the unselected wireless device.

3. The method of claim 1 , further comprising:
instructing the one or more unselected wireless devices to communicate with the access node via the first relay node when the first relay node is capable of receiving at least a same number of data streams as being sent by the unselected wireless device.

4. The method of claim 1 , further comprising:
randomly selecting a first time period and a second time period;
instructing a first group of the unselected wireless devices to communicate with the access node via the first relay node during the first time period using the first network protocol; and
instructing a second group of the unselected wireless devices to communicate with the access node via the second relay node during the second time period using a second network protocol.

5. The method of claim 4 , wherein the first network protocol is LTE and the second network protocol is WiFi.

6. The method of claim 1 , further comprising:
deselecting the first relay node based on at least one of the power storage level, a wireless device mobility, and channel conditions of a communication link assigned to the first relay node.

7. The method of claim 1 , further comprising:
selecting the at least one second wireless device from the plurality of wireless devices to operate as the second relay node based on a measured uplink packet delay meeting a delay threshold.

8. The method of claim 7 , further comprising:
assigning a first time period and a second time period to each of the unselected wireless devices;
instructing the unselected wireless devices to communicate with the access node via the first relay node during the first time period using the first network protocol; and,
instructing the unselected wireless devices to communicate with the access node via the second relay node during the second time period using the first network protocol.

9. The method of claim 8 , wherein a delay time is added to the second time period of one or more of the unselected wireless devices when the second relay node cannot meet a Quality of Service (QoS) requirement of the unselected wireless devices.

10. The method of claim 9 , wherein the first time period and the second time period are each randomly determined time periods.

11. A system for reducing wireless communication overhead, comprising:
a processing node configured to:
determine, at an access node, that resource request traffic generated from a plurality of wireless devices meets a buffer status reporting threshold;
select at least one wireless device from the plurality of wireless devices to operate as a first relay node, the at least one wireless device being selected based on:
a power storage level,
an assigned modulation and coding scheme (MCS), and
a capability to receive multiple data streams;

instruct one or more unselected wireless devices to communicate with the access node via the first relay node using a first network protocol;
aggregate, at the first relay node, resource request traffic from the one or more unselected wireless devices in communication with the access node via the first relay node, the first relay node being configured to communicate the aggregated resource request traffic to the access node using the first network protocol; and
when the aggregated resource request traffic from the first relay node meets a first traffic threshold, instruct at least one second wireless device from the plurality of wireless devices to operate as a second relay node.

12. The system of claim 11 , wherein the processing node is further configured to:
select the one or more unselected wireless devices from the plurality of wireless devices based on at least one of an application requirement and a service quality requirement of an application running on the unselected wireless device.

13. The system of claim 11 , wherein the processing node is further configured to:
instruct the one or more unselected wireless devices to communicate with the access node via the first relay node when the first relay node is capable of receiving at least a same number of data streams as being sent by the unselected wireless device.

14. The system of claim 11 , wherein the processing node is further configured to:
randomly select a first time period and a second time period, the first time period being assigned to a first group of unselected wireless devices and the second time period being assigned to a second group of unselected wireless devices;
instruct the first group of unselected wireless devices to communicate with the access node via the first relay node during the first time period using the first network protocol; and
instruct the second group of unselected wireless devices to communicate with the access node via the second relay node during the second time period using a second network protocol.

15. The system of claim 14 , wherein the first network protocol is LTE and the second network protocol is WiFi.

16. The system of claim 11 , wherein the processing node is further configured to:
deselect the first relay node based on at least one of the power storage level, a wireless device mobility, and channel conditions of a communication link assigned to the first relay node.
