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 that buffer status report traffic received at an access node from a plurality of wireless devices meets a first threshold;
selecting at least one of the plurality of wireless devices to operate as a router wireless device based on a power storage level and an assigned modulation and coding scheme (MCS);
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 a communication network via the selected router wireless device during the first time period;
instructing the unselected wireless devices to communicate with the communication network via the access node during the second time period, wherein a delay time is added to the second time period of at least one of the unselected wireless devices when the selected router wireless device cannot meet a quality of service requirement of the unselected wireless devices;
measuring an uplink packet delay of each of the unselected wireless devices; and
when an uplink packet delay meets a second threshold and communication resource request traffic from the selected router wireless device meets the first threshold, selecting at least a second one of the plurality of wireless devices to operate as a router wireless device.

2. The method of claim 1 , wherein the first time period and the second time period are each randomly determined time periods.

3. The method of claim 1 , wherein a random delay time is added before the first time period for each of the unselected wireless devices.

4. A system of reducing wireless communication overhead, comprising:
a processing node configured to:
determine that buffer status report traffic received at an access node from a plurality of wireless devices meets a first threshold;
select at least one of the plurality of wireless devices to operate as a router wireless device based on a power storage level and an assigned modulation and coding scheme (MCS);
assign a first time period and a second time period to each of the unselected wireless devices;
instruct the unselected wireless devices to communicate with a communication network via the selected router wireless device during the first time period; and
instruct the unselected wireless devices to communicate with the communication network via the access node during the second time period, wherein a delay time is added to the second time period of at least one of the unselected wireless devices when the selected router wireless device cannot meet a quality of service requirement of the unselected wireless devices;
measure an uplink packet delay of each of the unselected wireless devices; and
when an uplink packet delay meets a second threshold and communication resource request traffic from the selected wireless device meets the first threshold, select at least a second one of the plurality of wireless devices to operate as a router wireless device.

5. The system of claim 4 , wherein the first time period and the second time period are each randomly determined time periods.

6. The method of claim 4 , wherein the processing node is further configured to add a random delay time for each of the unselected wireless devices before the first time period.
