Control channel signaling using code points for indicating the scheduling mode

摘要

The invention relates to a control channel signal for use in a mobile communication system providing at least two different scheduling modes. Further the invention relates to a scheduling unit for generating the control channel signal and a base station comprising the scheduling unit. The invention also relates to the operation of a mobile station and a base station for implementing a scheduling mode using the control channel signal proposed by the invention. In order to facilitate the use of different scheduling schemes for user data transmission while avoiding an additional flag for indicating the scheduling mode in the control signaling, the invention proposes the use of code points in existing control channel signal fields. Further, the invention proposes a specific scheduling mode for use in combination with the proposed new control channel signal according to the invention. According to this scheduling mode control channel information is only provided for retransmissions, while initial transmissions are decoded using blind detection.

1. A method for use in a mobile station communicable with a base station that provides a dynamic scheduling mode and a persistent scheduling mode, the method comprising:
receiving from the base station a control channel signal that includes at least an RV (redundancy version) field and a HARQ (Hybrid Automatic Repeat request) process field, and in case a value in the RV field and a value in the HARQ process field in the received control channel signal at least partially constitute a predetermined combination, selecting the persistent scheduling mode to communicate with the base station, wherein the value in the RV field and the value in the HARQ process field are predetermined values and the predetermined combination is used to indicate a code point for selecting the persistent scheduling mode, and wherein the code point is used to indicate to the mobile station a control channel format, which defines contents and interpretation of fields in the control channel signal.
