Abstract

Disclosed is a base station transmitting multiple beams to multiple beam areas, including: a determination unit determining at least any one of whether a downlink control signal is transmitted through the multiple beams transmitted to the multiple beam areas and a transmission section; a generation unit generating signal transmitting control information including at least any one of whether the downlink control signal is transmitted, the transmission section of the downlink control signal, and derivation information to derive a change of an access beam for a terminal that accesses the multiple beams; a communication unit downlink-transmitting the signal transmitting control information to the multiple beam areas or the multiple beams; and a control unit controlling transmission of the downlink control signal based on the signal transmitting control information.

First claim

What is claimed is:

1. An operation method performed in a first base station supporting transmission based on multiple beams, the operation method comprising:
configuring, for respective multiple beams, a non-consecutive signal transmission interval in which a control signal is not transmitted;
transmitting information indicating the non-consecutive signal transmission interval; and
in the non-consecutive signal transmission interval, stopping transmission of the control signal through a beam#n to which the non-consecutive signal transmission interval is applied among the multiple beams, and transmitting the control signal through a beam#m to which the non-consecutive signal transmission interval is not applied among the multiple beams, wherein each of the n and the m is a positive integer.

2. The operation method of claim 1 , wherein the information indicating the non-consecutive signal transmission interval is at least one of an index and a number of respective frame, subframe, slot, and symbol.

3. The operation method of claim 1 , wherein the information indicating the non-consecutive signal transmission interval is information of frequency band in which the control signal is not transmitted.

4. The operation method of claim 1 , wherein the information indicating the non-consecutive signal transmission interval is transmitted through the multiple beams or the beam#n to which the non-consecutive signal transmission interval is applied.

5. The operation method of claim 1 , wherein the control signal includes at least one of a downlink control channel, a broadcasting channel, a reference signal, or a synchronization signal.

6. The operation method of claim 1 , further comprising transmitting information indicating the beam#n to which the non-consecutive signal transmission interval is applied.

7. The operation method of claim 1 , wherein the non-consecutive signal transmission interval for the beam#n is configured to be not overlapped with a non-consecutive signal transmission interval for a neighboring beam#(n+1) to the beam#n among the multiple beams.

8. The operation method of claim 1 , wherein a size of the non-consecutive signal transmission interval for respective multiple beams is configured identically.

9. The operation method of claim 1 , wherein, when the beam#n of the first base station is overlapped with a beam#l of a second base station, the non-consecutive signal transmission interval for the beam#n is configured to be not overlapped with a non-consecutive signal transmission interval for the beam#l, wherein the l is a positive integer.

10. An operation method performed in a terminal in a communication network, the operation method comprising:
receiving, from a base station supporting transmission based on multiple beams, information indicating a non-consecutive signal transmission interval in which a control signal is not transmitted; and
when the non-consecutive signal transmission interval is configured for a beam#n supporting an area to which the terminal belongs among the multiple beams, stopping a receiving operation of the control signal in the non-consecutive signal transmission interval, and performing the receiving operation of the control signal in an interval except for the non-consecutive signal transmission interval, wherein the n is a positive integer.

11. The operation method of claim 10 , wherein the information indicating the non-consecutive signal transmission interval is at least one of an index and a number of respective frame, subframe, slot, and symbol.

12. The operation method of claim 10 , wherein the information indicating the non-consecutive signal transmission interval is information of frequency band in which the control signal is not transmitted.

13. The operation method of claim 10 , wherein the control signal includes at least one of a downlink control channel, a broadcasting channel, a reference signal, or a synchronization signal.

14. The operation method of claim 10 , further comprising receiving information indicating the beam#n to which the non-consecutive signal transmission interval is applied.

15. A first base station supporting transmission based on multiple beams, comprising:
a processor; and
a memory storing at least one command executed by the processor,
wherein the at least one command is executed to configure, for respective multiple beams, a non-consecutive signal transmission interval in which a control signal is not transmitted;
transmit information indicating the non-consecutive signal transmission interval; and
in the non-consecutive signal transmission interval, stop transmission of the control signal through a beam#n to which the non-consecutive signal transmission interval is applied among the multiple beams, and transmit the control signal through a beam#m to which the non-consecutive signal transmission interval is not applied among the multiple beams, wherein each of the n ant the m is a positive integer.

16. The first base station of claim 15 , wherein the information indicating the non-consecutive signal transmission interval is transmitted through the multiple beams or the beam#n to which the non-consecutive signal transmission interval is applied.

17. The first base station of claim 15 , wherein the control signal includes at least one of a downlink control channel, a broadcasting channel, a reference signal, or a synchronization signal.

18. The first base station of claim 15 , wherein the non-consecutive signal transmission interval for the beam#n is configured to be not overlapped with a non-consecutive signal transmission interval for a neighboring beam#(n+1) to the beam#n among the multiple beams.
