METHOD FOR SENDING SIGNALS OF PHYSICAL MIXED INFORMATION CHANNEL OF REPEATED TRANSMISSION IN THE TIME INTERVAL OF THE PILOT SIGNAL DOWN FREQUENCY

摘要

1. A method for sending signals of a physical mixed information channel retransmission (PHICH), characterized in that the base station sends a PHICH signal on one or more characters in the downlink pilot time slot (DwPTS), and during transmission, used PHICH OFDM character arrangements are not the same as the character arrangements used by the first and second synchronization signal. ! 2. The method according to claim 1, characterized in that the signaling method is used for the LTE system according to the time division multiplexing type, and in the frame structure of the system, one 10 ms wireless frame is divided into two half-frames, each half-frame is divided into ten time slots 0.5ms, every two slots enter a 1ms subframe, one wireless frame includes ten subframes numbered 0 to 9, one wireless frame includes twenty slots numbered 0 to 19, indicated DwPTS is in subframe 1 and 6.! 3. A method according to claim 2, characterized in that the included sign in said time interval is an orthogonal frequency division multiplexing sign. ! 4. The method according to claim 2, characterized in that, with the signaling indicator in said DwPTS, the number of characters for transmitting PHICH signals is one or two or three. ! 5. The method according to one of claims 1-4, characterized in that on the first character in the DwPTS is sent the specified first synchronization signal; when the number of characters for PHICH signaling is one, the specified PHICH signal is sent on the second character in the DwPTS; when the number of characters for PHICH signaling is two, the second
