Abstract

The present disclosure relates to a pre-5 th -Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4 th -Generation (4G) communication system such as Long Term Evolution (LTE). Embodiments of the present invention provide a method and an apparatus for adaptively determining a beam sweeping pattern of a base station in a beamforming-based wireless communication system. An embodiment of the present invention provides an operating method of a serving base station in a wireless communication system, the operating method comprising: receiving, from at least one terminal, beam collision information indicating a collision between beams received from the serving base station and at least one neighboring base station adjacent to the serving base station; and adjusting a beam sweeping pattern of a beam transmitted to the at least one terminal on the basis of the received beam collision information. Various other embodiments of the present invention are also disclosed.

First claim

determining a beam sweeping pattern based on a beam and resources for a signal which is transmitted to at least one terminal; receiving, from the at least one terminal, beam collision information indicating a collision of beams transmitted from the serving BS and at least one neighboring BS; and adjusting, based on the beam collision information, the beam sweeping pattern.

17 . The method of claim 16 , wherein the beam collision information is determined based on a signal quality of a beam selected among a plurality of beams transmitted from the serving BS and a signal quality of a beam selected among a plurality of beams transmitted from the neighboring BS.

18 . The method of claim 16 , further comprising:
detecting the collision of beams; and transmitting a request for the beam collision information to the at least one terminal.

19 . The method of claim 16 , further comprising transmitting a message comprising a result of the adjustment of the beam sweeping pattern to the at least one terminal.

20 . The method of claim 16 , further comprising transmitting an end notification message indicating that the adjustment of the beam sweeping pattern ends to the neighboring BS.

21 . The method of claim 16 , wherein adjusting the beam sweeping pattern comprises:
detecting collision of beams based on the collected beam collision information; and changing the beam sweeping pattern of the beam transmitted to the at least one terminal when the beam collision is detected.

22 . The method of claim 16 , wherein adjusting the beam sweeping pattern comprises selecting a beam sweeping pattern making a total sum or a maximum value of an amount of interference, which the serving BS receives, among the plurality of beam sweeping patterns.

23 . An appratus of a serving base station (BS) in a wireless communication system, the apparatus comprising:
a transceiver; and a processor coupled to the transceiver, wherein the processor is configured to:
determine a beam sweeping pattern based on a beam and resources for a signal which is transmitted to at least one terminal,
receive, from the at least one terminal, beam collision information indicating a collision of beams transmitted from the serving BS and at least one neighboring BS, and
adjust, based on the beam collision information, the beam sweeping pattern.

24 . The apparatus of claim 23 , wherein the beam collision information is determined based on a signal quality of a beam selected among a plurality of beams transmitted from the serving BS and a signal quality of a beam selected among a plurality of beams transmitted from the neighboring BS.

detect the collision of beams; and transmit a request for the beam collision information to the at least one terminal.

26 . The apparatus of claim 23 , wherein the processor is further configured to transmit a message comprising a result of the adjustment of the beam sweeping pattern to the at least one terminal.

27 . The apparatus of claim 23 , wherein the processor is further configured to transmit an end notification message indicating that the adjustment of the beam sweeping pattern ends to the neighboring BS.

28 . The apparatus of claim 23 , wherein the processor is configured to:
detect collision of beams based on the collected beam collision information; and change the beam sweeping pattern of the beam transmitted to the at least one terminal when the beam collision is detected.

29 . The apparatus of claim 23 , wherein the processor is configured to select a beam sweeping pattern making a total sum or a maximum value of an amount of interference, which the serving BS receives, among the plurality of beam sweeping patterns.

30 . An apparatus of a terminal in a wireless communication system, the apparatus comprising:
a transceiver; and a processor coupled to the transceiver, wherein the processor is configured to:
generate beam collision information indicating a collision of beams received from a serving base station (BS) and at least one neighboring BS; and
transmit the beam collision information to the serving BS.

31 . The apparatus of claim 30 , wherein the beam collision information is determined based on a signal quality of a beam selected among a plurality of beams transmitted from the serving BS and a signal quality of a beam selected among a plurality of beams transmitted from the neighboring BS.

32 . The apparatus of claim 30 , wherein the processor is further configured to:
detect the collision of beams; and transmit a request for the beam collision information to the at least one terminal.

33 . The apparatus of claim 30 , wherein the processor is further configured to receive a message comprising a result of the adjustment of the beam sweeping pattern from the serving BS.

34 . The apparatus of claim 30 , wherein the processor is further configured to generate the beam collision information in response to a request for the beam collision information from the serving BS.
