Abstract

A system includes a first device to classify data as one of a control message or a non-control message, and provide the classification of the data to a second device. The second device receives the classification of the data, receives information associated with a resource, calculates an expected interference associated with the resource based on the information associated with the resource, and allocates, to the resource, data classified as a control message when the expected interference corresponds to a low expected interference.

Claims

1. (canceled)

2. A method implemented by a user equipment in a wireless communication system that includes a plurality of cells, the method comprising:

classifying data to be transmitted as one of a Radio Resource Control (RRC) message or a non-RRC message;

providing the classification to a base station;

responsive to providing the classification, receiving information from the base station identifying which of a plurality of resources in a cell to use for transmitting data comprising an RRC message, the identified resource having an expected inter-cell interference value that is less than another expected inter-cell interference value corresponding to another of the plurality of resources, wherein the expected inter-cell interference level of the identified resource is calculated by the base station using one or both of a fractional load Inter-cell Interference Coordination (ICIC) mechanism and a frequency reuse ICIC mechanism; and

transmitting the data via the identified resource.

3. The method of claim 2, where the providing comprises providing the classification via one or both of a modified buffer status report and a scheduling request format for data classified as an RRC message.

4. The method of claim 2, wherein the receiving comprises receiving information from the base station identifying an RRC resource set and a non-RRC resource set, and wherein the transmitting comprises mapping the data to one or more resources included in the RRC resource set if the data is classified as an RRC message.

5. A user equipment comprising:

a classifier circuit configured to classify data to be transmitted as one of a Radio Resource Control (RRC) message or a non-RRC message, and to provide the classification to a base station;

a scheduler circuit configured to receive information from the base station in response to the classifier circuit providing the classification to the base station, the received information identifying which of a plurality of resources in a cell to use for transmitting data comprising an RRC message, the identified resource having an expected inter-cell interference value that is less than another expected inter-cell interference value corresponding to another of the plurality of resources, wherein the expected inter-cell interference level of the identified resource is calculated by the base station using one or both of a fractional load Inter-cell Interference Coordination (ICIC) mechanism and a frequency reuse ICIC mechanism; and

a transmitter circuit configured to transmit the data via the identified resource.

6. The user equipment of claim 5, wherein the scheduler circuit is configured to receive information from the base station identifying an RRC resource set and a non-RRC resource set and to map the data to one or more resources included in the RRC resource set if the data is classified as an RRC message.

7. The user equipment of claim 5, wherein the classifier circuit is configured to provide the classification via one or both of a modified buffer status report and a scheduling request format for data classified as an RRC message.

8. The user equipment of claim 5, wherein the identified resource is associated with a level of expected inter-cell interference having a value less than a desired threshold value.
