Abstract

According to one aspect of the disclosure, a baseband chip is provided. The baseband chip may include a set of transmission command queues each associated with a different component carrier (CC) and each configured to maintain packet descriptors associated with one of the different component carriers (CCs). The baseband chip may also include a Layer 2 microcontroller. The Layer 2 microcontroller may be configured to generate the packet descriptors for each of the different CCs based on associated uplink (UL) grant indicators. The Layer 2 microcontroller may be configured to send each of the packet descriptors to the set of transmission command queues based on CC. The Layer 2 microcontroller may be configured to select a credit-based scheduling mechanism from a set of credit-based scheduling mechanisms. The Layer 2 microcontroller may be configured to configure a transmission scheduler with the credit-based scheduling mechanism.
