Abstract

A multi-beam transmitting and receiving apparatus in a wireless communication system includes a plurality of transmitting beam forming units for forming timely-divided multiple beams, each of the timely-divided multiple beams having a period of a total number of time division NTD at every time TD when the beams are activated; and a beam controller for controlling the transmitting beam forming units to select an arbitrary beam forming unit of a plurality of the transmitting beam forming units according to information about the time division, wherein the number of the beam forming units is determined as the total number of the beams NBM divided by the number of time division NTD.

Claims

1. A multi-beam transmitting apparatus in a wireless communication system, the apparatus comprising:

a plurality of transmitting beam forming units for forming timely-divided multiple beams, each of the timely-divided multiple beams having a period of a total number of time division NTD at every time TD when the beams are activated; and

a beam controller for controlling the transmitting beam forming units to select an arbitrary beam forming unit of a plurality of the transmitting beam forming units according to information about the time division,

wherein the number of the beam forming units is determined as the total number of the beams NBM divided by the number of time division NTD.

2. The multi-beam transmitting apparatus of claim 1, wherein the beam controller controls the transmitting beam forming units to select the beam forming unit according to information about an activation or inactivation state of subscribers in a service area of the wireless communication system.

3. The multi-beam transmitting apparatus of claim 2, wherein the transmitting apparatus forms transmitting beams of the transmitting beam forming unit as the timely-divided multiple beams by the control of the beam controller.

4. The multi-beam transmitting apparatus of claim 2, wherein the transmitting apparatus forms the beams of the transmitting beam forming units as adaptive-type timely-divided multiple beams which are temporarily activated or inactivated by control of the beam controller according to an activation or inactivation state of subscribers.

5. A multi-beam receiving apparatus in a wireless communication system, the device comprising:

a plurality of receiving beam forming units for forming timely-divided multiple beams, each of the timely-divided multiple beams having a period of time division NTD at every time TD when the beams are activated; and

a beam controller for controlling the receiving beam forming units to select an arbitrary beam forming unit of the receiving beam forming units according to information about the time division,

wherein the number of the beam forming units is determined as the total number of the beams NBM divided by the number of time division NTD.

6. The multi-beam receiving apparatus of claim 5, wherein the beam controller controls the receiving beam forming units to select the beam forming unit according to information about an activation or inactivation state of subscribers in a service area of the wireless communication system.

7. The multi-beam receiving apparatus of claim 6, wherein the receiving apparatus forms receiving beams of the receiving beam forming unit as the timely-divided multiple beams by the control of the beam controller.

8. The multi-beam receiving apparatus of claim 6, wherein the receiving apparatus forms the beams of the receiving beam forming units as adaptive-type timely-divided multiple beams which are temporarily activated or inactivated by control of the beam controller according to an activation or inactivation state of subscribers.

9. A multi-beam transmitting and receiving apparatus in a wireless communication system, the apparatus comprising:

a plurality of transmitting and receiving beam forming units for forming timely-divided multiple beams, each of the timely-divided multiple beams having a period of a total number of time division NTD at every time TD when the beams are activated; and

a beam controller for controlling the transmitting and receiving beam forming units to select an arbitrary beam forming unit of the transmitting and receiving beam forming units according to information about the time division,

wherein the number of the beam forming units is determined as the total number of the beams NBM divided by the number of time division NTD.

10. The multi-beam transmitting and receiving apparatus of claim 9, wherein the beam controller controls the transmitting and receiving beam forming units to select the beam forming unit according to information about an activation or inactivation state of subscribers in a service area of the wireless communication system.

11. The multi-beam transmitting and receiving apparatus of claim 10, wherein the transmitting and receiving apparatus forms both transmitting beams of the transmitting beam forming unit and receiving beams of the receiving beam forming unit as the timely-divided multiple beams by the control of the beam controller.

12. The multi-beam transmitting and receiving apparatus of claim 10, wherein the transmitting and receiving apparatus forms transmitting beams of the transmitting beam forming unit as adaptive-type timely-divided multiple beams which are temporarily activated or inactivated by control of the beam controller according to the activation or inactivation state of the subscribers and forms receiving beams of the receiving beam forming unit as the timely-divided multiple beams.

13. The multi-beam transmitting and receiving apparatus of claim 10, wherein the transmitting and receiving apparatus forms transmitting beams of the transmitting beam forming unit as the timely-divided multiple beams and forms receiving beams of the receiving beam forming unit as adaptive-type timely-divided multiple beams which are temporarily activated or inactivated.

14. The multi-beam transmitting and receiving apparatus of claim 10, wherein the transmitting and receiving apparatus forms the beams of the transmitting and receiving beam forming units as adaptive-type timely-divided multiple beams which are temporarily activated or inactivated by control of the beam controller according to an activation or inactivation state of subscribers.
