Wireless device for improving operating efficiency

Abstract

A wireless device is provided. The wireless device includes a first transmitting circuit, a second transmitting circuit and a controller. The first transmitting circuit is arranged to transmit a signal in a first band. The second transmitting circuit is arranged to selectively transmit a signal in the first band or in a second band according to a first control signal, wherein the second band is different from the first band. The controller is arranged to set the first control signal according to a transmission mode.

What is claimed is: 
     
         1 . A wireless device, comprising:
 a first transmitting circuit, arranged to transmit a signal in a first band; and   a second transmitting circuit, arranged to selectively transmit a signal in the first band or in a second band according to a first control signal, wherein the second band is different from the first band; and   a controller, arranged to set the first control signal according to a transmission mode.   
     
     
         2 . The wireless device of  claim 1 , when the transmission mode does not use the second band, the first control signal set by the controller controls the second transmitting circuit to perform signal transmission in the first band. 
     
     
         3 . The wireless device of  claim 1 , wherein when the transmission mode uses the second band, the first control signal set by the controller controls the second transmitting circuit to perform signal transmission in the second band. 
     
     
         4 . The wireless device of  claim 1 , wherein the second transmitting circuit comprises a plurality of transmitters, each arranged to selectively perform signal transmission in the first band or signal transmission in the second band according to the first control signal. 
     
     
         5 . The wireless device of  claim 1 , wherein the first transmitting circuit is further arranged to selectively perform signal transmission in the first band or signal transmission in the second band according to a second control signal; and the controller is further arranged to set the second control signal according to another transmission mode. 
     
     
         6 . The wireless device of  claim 5 , wherein the second control signal set by the controller controls the first transmitting circuit to perform signal transmission in the first band. 
     
     
         7 . The wireless device of  claim 5 , wherein when the first transmitting circuit does not perform signal transmission in the first band, the second control signal set by the controller controls the first transmitting circuit to perform signal transmission in the second band. 
     
     
         8 . The wireless device of  claim 5 , wherein the second transmitting circuit comprises a plurality of transmitters, each arranged to selectively perform signal transmission in the first band or signal transmission in the second band according to the first control signal. 
     
     
         9 . The wireless device of  claim 5 , wherein the first transmitting circuit comprises a plurality of transmitters, each arranged to selectively perform signal transmission in the first band or signal transmission in the second band according to the second control signal. 
     
     
         10 . The wireless device of  claim 1 , wherein the first band and the second band are non-continuous bands.
