Systems and methods to enhance radio link performance in a multi-carrier environment
First Claim
1. A system, comprising:
- a macro cell, the macro cell implementing a plurality of network layers, wherein the plurality of network layers comprise, at least;
a physical layer; and
a media access control (“
MAC”
) layer; and
a small cell, the small cell implementing at least one of the plurality of network layers;
wherein the MAC layer controls the flow of data packets to and from the physical layer of the macro cell;
wherein the plurality of network layers implemented by the small cell further comprises a MAC layer;
wherein the MAC layer of the small cell coordinates with the MAC layer of the macro cell to control the flow of data packets to and from the physical layer to the macro cell and to control the flow of data packets to and from the physical layer of the small cell; and
wherein the MAC layer of the macro cell controls the flow of the data packets to and from the physical layer of the small cell.

Abstract
Described herein are systems and methods to enhance radio link performance in a multi-carrier environment. A method may comprise sending, by an upper level layer of a wireless device, user data in a packet for transmission, wherein the packet includes an indication of a level of priority of the packet, receiving, by a media access control (“MAC”) layer of the wireless device, the packet for transmission including the indication of the level of priority provided by the upper level layer, identifying, by the MAC layer, a reliability of each of a plurality of component carriers, and selecting, by the MAC layer, one of the component carriers on which to transmit the packet, wherein the selecting is based on the level of priority of the packet and the reliability of the one of the component carriers.
