Abstract

Methods and apparatuses are provided that facilitate providing quality of service for similar priority logical channels at least in part by assigning dynamic priority levels to the logical channels to allow certain logical channels to be assigned resources before other logical channels. Dynamic priority levels can be assigned based at least in part on a total accumulated used bytes of a given logical channel scaled by a prioritized bit rate of the logical channel. Thus, logical channels with a lower number of total accumulated used bytes scaled by the prioritized bit rate can be assigned higher priority to ensure resources are assigned to the logical channels. Moreover, the dynamic priority levels can be normalized to align the dynamic priority levels within certain values so as not to interfere with other logical channels of different assigned priority.

Claims

1. A method for wireless communication, comprising:

identifying a set of logical channels with at least substantially equal priority; and

determining a dynamic priority level for a logical channel in the set of logical channels based at least in part on a total accumulated used bytes of the logical channel scaled by a prioritized bit rate of the logical channel.

2. The method of claim 1, further comprising normalizing the dynamic priority level for the logical channel based at least in part on disparate dynamic priority levels of one or more other logical channels in the set of logical channels.

3. The method of claim 2, wherein the normalizing further comprises applying an assigned priority of the logical channel to the dynamic priority level.

4. The method of claim 3, wherein the applying the assigned priority includes adding the assigned priority to the dynamic priority level.
