METHOD AND APPARATUS FOR INDICATING A TRANSMISSION STATUS TO A HIGHER LAYER
First Claim
1. A method for indicating a transmission status to a higher layer, the method comprising:
- a higher layer entity generating a higher layer message;
a radio link control (RLC) entity sending at least one RLC protocol data unit (PDU) carrying at least one segment of the higher layer message to a medium access control (MAC) entity;
the MAC entity transmitting at least one transport block carrying said at least one RLC PDU via a hybrid automatic repeat request (HARQ) entity; and
the RLC entity sending a packet delivery notification regarding delivery status of the higher layer message to the higher layer entity based on HARQ feedback information obtained from the HARQ entity.

Abstract
A method and apparatus for indicating a transmission status to a higher layer are disclosed. In the transmitting entity, a radio link control (RLC) entity sends a packet delivery notification regarding delivery status of a higher layer message to a higher layer entity based on hybrid automatic repeat request (HARQ) feedback information obtained from an HARQ entity. The RLC entity may send the packet delivery notification to the higher layer entity based on an RLC status report. Alternatively, the HARQ entity may send the packet delivery notification to the higher layer entity and/or the RLC entity based on HARQ feedback. The higher layer entity may update the higher layer message before retransmitting the higher layer message. If the RLC entity segments an RLC service data unit (SDU) and delivery of at least one segment of the RLC SDU fails, the RLC entity may discard the RLC SDU.
