Possesses the user terminal of flexible bandwidth configuration feature by center from the position transfer of direct current carrier to virtual direct current
Frequency range centered on carrier wave is started to work.If the wide synchronizing sequence of master tape is fallen into bandwidth of operation, then can use the PSS
With the PRB where SSS, such as master tape in Fig. 2, wide synchronizing sequence is fallen into the bandwidth of operation of following two terminal, then can be made
With the PRB resources.Since the wide PSS and SSS sequences of master tape are the time-divisions, network side is dispatched, it is possible to achieve：The terminal when sending
The PRB resources cannot be used, the PRB resources can be used by not sending terminal.So as to further increase the utilization of PRB resources
Rate.
Optionally, terminal transmits data without using the Physical Resource Block where the synchronizing sequence of virtual direct current carrier both sides.
According to the principle of few existing system of the modification based on standard agreement as far as possible, terminal will not use virtual direct current carrier and
The synchronizing sequence of its both sides, in order to on existing system framework carry out this patent application, reduce application implementation into
This.
Optionally, spread bandwidth can be located at the wide one or both sides of master tape.Spread bandwidth can include more than two sections
The combination of bandwidth.
In addition, the terminal for possessing flexible bandwidth configuration feature in this patent can be divided into two classes, one kind is a support standard
The terminal of bandwidth, this Terminal Type only support this six kinds of bandwidth of LTE standard 1.4M, 3M, 5M, 10M, 15M, 20M, but can be according to spirit
Band width configuration information living is transferred to different band operations, and the position of its direct current carrier position is also variable.Another is
It can support the terminal of any bandwidth of 1.4M to 20M, it is with the former only difference is that the configuration of support full bandwidth, supports scope
It is more flexible.For the flexible bandwidth configurating terminal for only supporting standard bandwidth, this patent is realized a variety of continuous different wide
The flexible combination of the bandwidth of degree, as 7MHz can be by 5MHz+5MHz or 5MHz+3MHz realizations, as long as meeting each of standard bandwidth
Kind combination.
