Embodiment Construction

[0043] In order to solve the problems in the prior art that using the common control channel to transmit the available sub-band pattern needs to occupy additional air interface resources and increase the data transmission delay.

[0044] An embodiment of the present invention provides a transmission method.

[0045] Such as figure 1 As shown, the processing of this method at the sending end includes:

[0046] 101. Establish a mapping relationship between available sub-frequency band patterns and reference signal sequences.

[0047] If the entire frequency band is divided into N sub-frequency bands, according to the spectrum utilization, the transmitter can select all or part of the N sub-frequency bands for data transmission. If a sub-frequency band is used to transmit data, all All sub-carriers can be used to transmit data, if a sub-frequency band is not used to transmit data, all sub-carriers in this sub-frequency band will not be used to transmit data. Since each sub-fre...

Abstract

The embodiment of the invention discloses transmission method, device and system, belonging to the communication field and solving the problems that the transmission of an available sub-frequency range pattern needs to occupy extra air interface resources and data transmission time delay is increased in the prior art. The transmission method of the invention comprises the steps of: establishing a mapping relationship between the available sub-frequency range pattern and a reference signal sequence; determining the reference signal sequence according to an obtained available sub-frequency range and the mapping relationship and sending a reference signal containing the reference signal sequence by a sender; and receiving the reference signal by a receiver, determining the reference signal sequence according to the reference signal, and determining the available sub-frequency range according to the reference signal sequence and the previously stored mapping relationship between the available sub-frequency range pattern and the reference signal sequence. The technical scheme provided by the embodiment of the invention can be applied to a wireless communication system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a transmission method, device and system. Background technique [0002] When the discontinuous available frequency band is used for communication, the specific available sub-frequency bands and unusable sub-frequency bands in the discontinuous available frequency band are represented by the available sub-frequency band pattern. [0003] In the prior art, before the transmitter uses the discontinuously available frequency band to send data, it transmits a control message to the receiver through the common control channel, and notifies the receiver of the available sub-frequency band pattern adopted by the transmitter, and the receiver obtains the discontinuously available frequency band After the available sub-band patterns are available, specific usable sub-bands and unusable sub-bands can be obtained according to the available sub-band patterns, so as to filter out signals on u...
