Abstract

The exemplary embodiments enable setting one or more devices of a wireless communication network to be associated with a one or more groups of a plurality of groups based on at least a device type of the one or more devices, receiving at least one indication that one or more devices have data to send, and allocating, one group at a time, resources to the groups associated with the devices with data to send. Further, receiving a probe message from a network node, the probe message identifying one or more groups set to the device based at least on a device type, sending, information to the node, the information providing an indication that data is required to be sent, and in response to the sending, receiving a resource allocation from the node to send the data, wherein the resource allocation is arranged based on the groups set to the device.

Claims

1. A method comprising:

setting, by a network node, one or more devices of a wireless communication network to be associated with a one or more groups of a plurality of groups based on at least a device type of the one or more devices;

receiving at least one indication that the one or more devices has data to send in the wireless communication network; and

allocating, one group at a time, a resource to the one or more groups associated with one or more devices with data to send.

2. The method according to claim 1, wherein the groups are assigned to the device based on at least one of a service level agreement, a quality of service required and a path loss experienced for the one or more devices.

3. The method according to claim 1, wherein the setting the one or more devices comprises receiving an indication of device identification from each one of the one or more devices, wherein the indication is received in response to a probe type message sent by the network node to the one or more devices, wherein the indication is received in an acknowledgement message, and wherein the indication comprises a sequence, and wherein the probe type message is comprised of an indication of a group of the one or more groups to be polled next, an indication of when the group will be polled, an indication of a transmit power class of the network node, and an indication of a target receive power of the indication.

7. The method according to claim 3, wherein the sequence is a Zadoff-Chu sequence.

8. The method according to claim 3, wherein the sequence identifies a size of the resource allocation needed to send the data.
