Abstract

A method and apparatus for a base station engaging in transmissions via at least a media access layer with a user entity are disclosed. The base station transmits data to the user entity over a high speed scheduling and packet data scheduling channels. The base station has a plurality of hybrid automatic repeat request (HARQ) entities cooperating with a scheduler for transmitting frames from at least the base station to the user entity for a given HARQ process. Each HARQ entity receives either a not acknowledge or an acknowledge signal or detects a discontinuous transmission for a given HARQ process. The base station transmits a next data indicator to the user entity. The user entity has at least one buffer associated with a given HARQ process. The buffer stores and performs incremental combining of received data relating to data from the base station. The buffer is capable of being flushed.
