Abstract
The present invention relates to a base station arrangement (20) in a communications system supporting high speed packet data communication, comprising a base station protocol entity for a protocol handling high speed control signalling and physical resource allocation for high speed data communication, quality handling means (27) adapted to receive and handle channel condition related information from mobile user stations, encoding means for encoding data packets to be transmitted to mobile user station, and transmission control means comprising a scheduling means (28) communicating with a hybrid automatic retransmission system (HARQ) (221, . . . , 22n) and being adapted to control transmission of data packets using said channel condition related information and data packet buffering means (231, . . . , 23n). The base station protocol entity further comprises a control plane entity supporting an extended control plane for control plane signalling messages comprising specific control messages handling means (26), adapted to provide a specific probing or information control message and to send said message to a mobile user station.
