Abstract
A method and apparatus for beamforming in a wireless communication system are provided. The method of supporting beamforming in a wireless communication device includes detecting a direction change of the wireless communication device while communicating with a peer device. The method of supporting beamforming in a wireless communication device also includes adjusting a beam direction for communication with the peer device based on information indicating a direction change of the wireless communication device.
Claims20
A method for operating a user equipment (UE), the method comprising:
- communicating with a peer device using a first beam;
- detecting a change in a direction of the first beam based on a movement of the UE;
- transmitting, to the peer device, a message for requesting that the UE performs a beam training in a part of an entire area based on an angle for the change in the direction of the first beam being greater than a predetermined threshold;
- in response to receiving from the peer device a response for the message, determining a first part for the beam training by the UE based on the angle for the change in the direction of the first beam;
- transmitting, to the peer device, information for the first part and the angle for the change in the direction of the first beam;
- receiving, from the peer device, information regarding a second part for the beam training by the peer device, wherein the second part is determined based on the first part and the angle for the change in the direction of the first beam;
- adjusting the first part based on the second part;
- determining a second beam by performing beam training in the adjusted first part;
- and
- communicating with the peer device using the second beam.
A user equipment (UE) comprising:
- a transceiver configured to communicate with a peer device using a first beam;
- and
- at least one processor configured to:
- detect a change in a direction of the first beam based on a movement of the UE,
- control to transmit, to the peer device, a message for requesting that the UE performs a beam training in a part of an entire area based on an angle for the change in the direction of the first beam being greater than a predetermined threshold,
- in response to receiving from the peer device a response for the message, determine a first part for the beam training by the UE based on the angle for the change in the direction of the first beam,
- control to transmit, to the peer device, information for the first part and the angle for the change in the direction of the first beam,
- control to receive, from the peer device, information regarding a second part for the beam training by the peer device, wherein the second part is determined based on the first part and the angle for the change in the direction of the first beam,
- adjust the first part based on the second part, and
- determine a second beam by performing beam training in the adjusted first part,
- wherein the transceiver is configured to communicate with the peer device using the second beam.
