Abstract:
1. A method for indicating by a first user equipment (UE) an end of a stream of data frames so as to transmit data to be transmitted by another UE after the end of a stream of the data frames in a mobile communication system, which includes a stream of data frames with transmission data, and a stream of control frames wherein, each of the control frame having TFCI (Transport Format Combination Indicator) field indicating a length of corresponding data frame, the method comprising the steps of; spreading the stream of control frames with a first orthogonal variable spreading factor (OVSF) code and the stream of data frames with a second orthogonal variable spreading factor (OVSF) code; transmitting the spread data in the data frames over an uplink common channel and the spread control data in the control frames over an uplink control channel from the first UE to a UTRAN (UMTS (Universal Mobile Telecommunications System) Terrestrial Radio Access Network); and upon transmission of the last one of the data frames, generating a specific control frame to represent end of data transmission by configuring a TFCI bits indicating the data frame block size being zero; and repeatedly transmitting the specific control frame to UTRAN over the uplink control channel.
