Abstract
Methods and apparatus for processing error control messages, such as RLC ARQ control messages, are disclosed. An exemplary method comprises signaling a medium access controller (MAC) that link resources are needed for transmitting data, receiving an indication from the MAC that link resources for transmitting the data are scheduled, and generating an error control message after receiving said indication, based on a current error control status. The error control message is then forwarded to the MAC for transmission. Because the generation of an error control message is delayed until resources for its transmission are scheduled, the queuing of stale control messages is avoided.
Claims16
A method for processing error control messages in a wireless communication system, the method comprising:
- signaling a medium access controller that link resources are needed for transmitting data;
- receiving an indication from the medium access controller that link resources for transmitting the data are scheduled;
- responsive to the indication, generating an error control message based on a current error control status;
- and
- forwarding the error control message to the medium access controller for transmission.
The method of claim I further comprising:
- receiving a notification that the error control message has been acknowledged;
- and
- starting an error control timer responsive to the notification.
A wireless communications apparatus comprising:
- a radio transceiver;
- a medium access controller operatively connected to the radio transceiver;
- and
- a radio link controller operatively connected to the medium access controller, wherein the radio link controller is configured to:
- signal the medium access controller that link resources are needed for transmitting data;
- receive an indication from the medium access controller that link resources for transmitting the data are scheduled;
- responsive to the indication, generate an error control message based on a current error control status;
- and
- forward the error control message to the medium access controller for transmission via the radio transceiver.
