Abstract
A method for multiplexing uplink pilot based on single carrier frequency division multiple access comprises the steps: the user terminal transmits the pilot signal on several sub-carriers within a symbol; and in the other symbol transmits the pilot signal on several sub-carriers which interleaves with the sub-carrier occupied in the previous symbol; time division multiplexes the said respective signal with the symbol in which the user terminal transmit the data signal. Wherein the user terminal could transmit the pilot signal on several sub-carriers within the said symbol under the direction of the network side. The invention also provides a user terminal and a method for multiplexing uplink pilot based on single carrier frequency division multiple access accordingly. The invention could decrease the interval between the sub-carriers occupied by pilot signal on the frequency field and thus achieve better interpolation processing effect.
A method for multiplexing uplink pilot based on single carrier frequency division multiple access comprises the steps: the user terminal transmits the pilot signal on several sub-carriers within a symbol; and in the other symbol transmits the pilot signal on several sub-carriers which interleaves with the sub-carrier occupied in the previous symbol; time division multiplexes the said respective signal with the symbol in which the user terminal transmit the data signal. Wherein the user terminal could transmit the pilot signal on several sub-carriers within the said symbol under the direction of the network side. The invention also provides a user terminal and a method for multiplexing uplink pilot based on single carrier frequency division multiple access accordingly. The invention could decrease the interval between the sub-carriers occupied by pilot signal on the frequency field and thus achieve better interpolation processing effect.
The invention claims uplink pilot-frequency multiplexing method based on single carrier wave frequency division multiple access (FDMA) comprising the step that the user terminal occupies multiple sub-carrier waves of the symbol to transmit the pilot-frequency signal; the transmission of the pilot-frequency signal is operated at the multiple sub-carrier waves with the crossed position formed by the way that the sub-carrier wave is occupied by another symbol and the previous symbol; each symbol and the symbol time-division of the data signal transmit by the user terminal are reused wherein the user terminal can occupy multiple sub-carrier waves of the symbol to transmit the pilot-frequency signal under the condition of the indication of the network. The invention also claims a user terminal and a pilot-frequency multiplexing method based on single carrier wave FDMA. The invention can reduce the interval of pilot-frequency sub-carrier wave occupied by the pilot-frequency symbol for the frequency scale thus obtaining well interpolation treatment effect.
