Method, apparatus and computer program for handling hybrid automatic repeat request failure

摘要

A method by which a Node B is informed by a serving radio network controller that a medium access control-e reset is to be performed by a user equipment in communication with the Node B, so that the Node B can then provide failure indications of all hybrid automatic repeat request processes that are not decoded by the time of the medium access control-e reset. Corresponding equipment and software are also provided.

1. A method, comprising:
receiving at a base station of a radio access network of a telecommunication system, from a controller of the radio access network, a reset information element indicating a time when a user equipment coupled to the base station will perform a reset of buffers used in hybrid automatic repeat request processing for communication on an uplink channel; and sending from the base station to the controller a hybrid automatic repeat request failure indication for a hybrid automatic repeat request process that was not decoded successfully before the buffer reset in the user equipment.
