Embodiment 1

[0085] According to an embodiment of the present invention, there is provided a data transmission method for a terminal to send or receive data on a borrowed frequency band, characterized in that: at least one receiving channel of the terminal receives cell synchronization signals on the home frequency band of the terminal, scheduling control command; the transmit channel of the terminal sends service signals and channel detection signals on the borrowed frequency band.

[0086] Through the data transmission method provided by the embodiment of the present invention, under the condition of the same number of radio frequency channels of the terminal, the frequency spectrum utilization efficiency can be significantly improved.

[0087] Wherein, the home frequency band and the borrowed frequency band are two frequency bands on an unpaired frequency spectrum with a guard interval, wherein, the uplink / downlink time slot in the radio frame on the home frequency band is the same as th...

Embodiment 2

[0092] According to an embodiment of the present invention, a data transmission method is also provided, which is used for direct communication between a first terminal and a second terminal on a non-home frequency band or a borrowed frequency band, wherein the first terminal and the second terminal communicate via Synchronization between its home frequency band and the wireless access point of the serving cell of the terminal, so as to realize the synchronization between the first terminal and the second terminal participating in the communication, wherein the first terminal and the second terminal are in their home The control signal from the wireless access point of the serving cell is received on the frequency band, and the channel detection signal is transmitted on the non-home frequency band or the borrowed frequency band.

[0093] Through the data transmission method provided by the embodiment of the present invention, under the condition of the same number of radio freq...

Embodiment 3

[0110] According to an embodiment of the present invention, a method for scheduling terminals is provided, which is used for scheduling terminals among different frequency bands.

[0111] The method for scheduling a terminal according to an embodiment of the present invention includes: the network side allocates the spectrum resources on the first frequency band and the second frequency band to the same terminal in time serially; Allocating resources on the first frequency band; within a second time interval, the network side allocates resources on the second frequency band to the terminal; wherein, the first time interval and the second time interval are included within the duration of one radio frame period.

[0112] Through the terminal scheduling method provided by the embodiment of the present invention, idle time slots on different frequency bands can be effectively used, and spectrum utilization efficiency can be significantly improved.

[0113] Wherein, there is a gap ...

Abstract

The invention discloses a wireless access network system, a terminal, a data transmission method and a method for scheduling the terminal. The wireless access network system comprises a data broadcasting subsystem, a frequency division duplex (FDD) subsystem and a time division duplex (TDD) subsystem. The data broadcasting subsystem comprises a first transmitting channel; the FDD subsystem comprises a second receiving channel and a second transmitting channel; and the TDD system comprises a third receiving channel and a third transmitting channel. Moreover, the first transmitting channel of the data broadcasting subsystem is configured to work on a first frequency band; the second transmitting channel of the FDD subsystem is configured to work on a second frequency band; and the third receiving channel and the third transmitting channel of the TDD subsystem are configured to work on a third frequency band, wherein the second frequency band is arranged between the first frequency band and the third frequency band as well as is adjacent to the first frequency band and the third frequency band. According to a technical scheme of the invention, a service efficiency of a frequency spectrum is improved by configuring a used frequency spectrum of a wireless access network system.
