The invention discloses a method which is used to send orthogonal frequency division multiplexing reused symbols, the method comprises: the first corresponding relationship which is the corresponding relationship of data and control signaling combination mode and control signaling time-frequency distribution information, control signaling time-frequency distribution information has the second corresponding relationship which is the corresponding relationship of the number of uplink resource unit and time-frequency resources, coding repeat factors, A. sender according to the combination mode of data and the control signaling and the first corresponding relationship determines the control signaling time-frequency distribution information, according to the number of uplink resource units andthe second corresponding relationship, determines time-frequency resources and coding repeat factors; according to time-frequency resources and coding repeat factors, the sender reuses the data and the control signaling to the orthogonal frequency division multiplexing symbols, and processes the orthogonal frequency division multiplexing symbols, and sends. Through the invention the problem of low system performance and efficiency is solved existed in current technologies is solved. The invention also discloses a system and device which is used to send orthogonal frequency division multiplexing reused symbols.
Description
technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method, system and device for sending OFDM symbols. Background technique [0002] In the current long-term evolution system (LTE) system scheme of the third generation mobile communication partnership (3GPP), it has been clarified that the uplink adopts a single-carrier transmission mode to reduce the peak-to-average power ratio of transmission and reduce the implementation cost of the terminal . And in the multiplexing mode of data and L1 / L2 control signaling, it is clearly stipulated to adopt the mode of time division multiplexing (TDM). The TDM-based multiplexing method uses fixed Orthogonal Frequency Division Multiplexing (OFDM) symbols to transmit control signaling. [0003] There are two types of L1 / L2 control signaling in the uplink of the LTE system: data accompanying control signaling, such as: transmission format and hybrid automatic repeat (HAR...
