The invention provides a communication system, a method and device for detecting a transmission format. The method comprises the following steps of: receiving a service signal, wherein a dedicated physical channel of the service signal comprises at least one transmission channel which is in a zero rate transmission format or a full rate transmission format; acquiring a noise power average value of the dedicated physical channel in a target time slot and a signal power average value of a target transmission channel of the dedicated physical channel in the target time slot; and acquiring the transmission format of the target transmission channel according to the ratio of the noise power average value of the dedicated physical channel in the target time slot to the signal power average value of the target transmission channel. The embodiment of the invention also provides a corresponding device and a communication system, and the application range of transmission format blind detection can be enlarged.
Description
technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a transmission format detection method, device and communication system. Background technique [0002] In the 3rd Generation Partnership Project (the 3 rd The Generation Partnership Project (hereinafter referred to as: 3GPP) proposed the standard of the third generation mobile communication system. According to the 3GPP agreement, in the Wideband Code Division Multiple Access (hereinafter referred to as: WCDMA) system, each transmission channel (Transmission Channel) , hereinafter referred to as: TrCH), the data carried on the transmission time interval (Transport Time Interval, hereinafter referred to as: TTI) as a periodic data transmission block, different transport channels have different TTI, each channel TTI and the current TTI The number of included information bits is defined by a transport format (Transport Format, hereinafter referred to as: TF). Mu...
