Abstract
The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). Methods and apparatuses are provided for devices in a wireless communication system. Information requesting a channel estimation by at least one second device is transmitted from a first device to the at least one second device. Channel information is received at the first device as feedback from the at least one second device.
Claims30
An operating method of a first device in a wireless communication system, the method comprising:
- transmitting, from the first device, to at least one second device, information requesting a channel estimation by the at least one second device;
- and
- receiving, at the first device, channel information as feed back from the at least one second device.
An operating method of a second device in a wireless communication system, the method comprising:
- receiving, from a first device, at the second device, information requesting a channel estimation;
- and
- transmitting, from the second device, channel information, which is generated based on the information, to the first device.
A first device in a wireless communication system, the first device comprising:
- a transmitter configured to transmit information requesting a channel estimation by at least one second device, to the at least one second device;
- and
- a receiver configured to receive channel information as feed back from the at least one second device.
A second device in a wireless communication system, the second device comprising:
- a receiver configured to receive information requesting a channel estimation from a first device;
- and
- a transmitter configured to transmit channel information, which is generated based on the information, to the first device.
A non-transitory computer readable medium with computer executable instructions stored thereon executed by a processor to perform the method of operating a first device in a wireless communication system, the method comprising:
- transmitting, to at least one second device, information requesting a channel estimation by the at least one second device;
- and
- receiving channel information as feed back from the at least one second device.
A non-transitory computer readable medium with computer executable instructions stored thereon executed by a processor to perform the method of operating a second device in a wireless communication system, the method comprising:
- receiving, from a first device, information requesting a channel estimation;
- and
- transmitting channel information, which is generated based on the information, to the first device.
