9. An apparatus configured to perform wireless communication with a wireless device, comprising:

a processing element operatively coupled to a radio, wherein the radio and the processing element are configured to:

establish a first radio bearer with the wireless device, wherein establishing the first radio bearer comprises selecting one or more physical channels for the first radio bearer of a plurality of possible physical channels, wherein the one or more physical channels for the first radio bearer are selected based at least in part on an application traffic pattern of a first application associated with the first radio bearer;

communicate application data associated with the first application with the wireless device via the first radio bearer;

establish a second radio bearer with the wireless device, wherein establishing the second radio bearer comprises selecting one or more physical channels for the second radio bearer of the plurality of possible physical channels, wherein the one or more physical channels for the second radio bearer are selected based at least in part on an application traffic pattern of a second application associated with the second radio bearer, wherein the one or more physical channels selected for the second radio bearer are different physical channels than the one or more physical channels selected for the first radio bearer; and

communicate application data associated with the second application with the wireless device via the second radio bearer.
