TX modem 132 is sent to receive the data of terminal to antenna element 120 to be passed through Encode and modulate, the signal of modulation is converted into analogue signal, and exports this analogue signal.? In this case, analog baseband signal is sent to TX RF chain 134 by TX modem 132.

TX RF chain 134 includes the multiple RF paths for sending a signal to respective antenna.This In the case of, TX RF chain 134 can be according to the beam pattern selected by beam selection unit 110 and wave beam Width simply uses some antenna and some RF path.

TX RF chain 134 baseband signal received from TX modem 132 is multiplexed to Few one is activated in RF path, the relevant baseband signal on each RF path is converted to RF letter Number, and send RF signal by antenna element 120.In this case, TX RF chain 134 Control baseband signal so that the beam pattern according to being selected by ripple beam selection unit 110 forms wave beam. Such as, multiple omnidirectional antenna 210-1 to 210-N as shown in Figure 2 A are included when antenna element 120 Time, TX RF chain 134 includes phase-shift unit 200-1 to 200-N, for being shifted through respective antenna RF path and the phase place of signal that sends.Phase-shift unit 200-1 to 200 N is according to by beam selection Beam pattern and beam angle that unit 110 selects shift the letter that will be sent by corresponding antenna Number phase place.

Fig. 3 shows the block diagram of the configuration of RF chain according to an exemplary embodiment of the present invention.

With reference to Fig. 3, when antenna element 120 includes multiple beam antenna 310-1 to 310 N, TX RF chain 134 includes switching 300, for according to beam pattern by TX modem 132 even Receive corresponding antenna.Switch 300 is according to the beam pattern selected by beam selection unit 110 and wave beam Width, is connected at least one antenna by TX modem 132.Here, switch 300 can be by TX modem 132 is connected at least one antenna.

RX RF chain 142 includes the multiple RF paths being received RF signal by respective antenna.At this In the case of Zhong, RX RF chain 142 can be according to the beam pattern selected by beam selection unit 110 and ripple Beam width and simply use some antenna and some RF path.

142, RX RF chain is converted to baseband signal from the RF signal that respective antenna receives, and will Baseband signal is sent to RX modem 144.In this case, RX RF chain 142 controls base Band signal, thus form wave beam according to the beam pattern selected by beam selection unit 110.Such as, When antenna element 120 includes multiple omnidirectional antenna 210-1 to 210-N as shown in Figure 2 A, RX RF chain 142 includes phase-shift unit 220-1 to 220 N, the letter received to be shifted through respective antenna Number phase place.Phase-shift unit 220-1 to 220 N is according to the beam pattern selected by beam selection unit 110 Case and beam angle, be shifted through respective antenna and the phase place of signal that receives.

In the exemplary embodiment, multiple beam antennas as shown in Figure 3 are included when antenna element 120 During 310-1 to 310-N, RX RF chain 142 includes switching 300, is used for RX according to beam pattern Modem 144 is connected to the antenna being correlated with.Switch 300 is according to being selected by beam selection unit 110 Beam pattern and beam angle RX modem 144 is connected at least one antenna.Here, RX modem 144 can be connected at least one antenna by switch 300.

The analogue signal received by RX RF chain 142 is converted to numeral by RX modem 144 Signal, and demodulate and decode digital signal.

The transmitting element 130 and the reception unit 140 that send terminal can share an antenna element each other 120, it is possible to use different antenna elements, or can be separated from each other.

Fig. 4 A and 4B shows the narrow ripple produced from aerial array according to an exemplary embodiment of the present invention Bundle pattern.Fig. 5 A and 5B shows broad beam pattern according to an exemplary embodiment of the present invention.

As it has been described above, the antenna element 120 sending terminal can include the sky of 5x5 as shown in Figure 4 A Linear array.In this case, sending terminal can use the aerial array of 5x5 to be formed such as Fig. 4 B Shown narrow beam.Such as, multiple beam antenna 310-1 as shown in Figure 3 are included when antenna element 120 During to 310 N, send the beam angle of terminal along with the antenna amount being used for sending/receiving signal Increase and increase.If it is to say, beam antenna is used, then when using an antenna, send The beam angle of terminal can be minimized.Therefore, terminal is sent by using corresponding antenna to be formed Narrow beam.

As another example, when antenna element 120 include as shown in Fig. 2 A or 2B multiple entirely When antenna 210-1 to 210 N, send the beam angle of terminal along with the quantity of the antenna used Increase and reduce.Therefore, send terminal and can form narrow beam by the phase place shifting multiple antennas.

Additionally, when antenna element 120 is configured as shown in Figure 4 A, sending terminal can be such as Fig. 5 A Shown in form vertical beam, to send synchronizing signal and common control signal.Such as, when antenna list Unit 120 is when including beam antenna, sends terminal vertical by use be included in antenna element 120 one Antenna in straight array generates vertical beam.Specifically, when sending terminal generation vertical beam Bc1 Time, only antenna A11, A21, A31, A41 and A51 of antenna element 120 is unlocked.
