FIELD: feedback means for direct connection.
SUBSTANCE: first configuration information is obtained, by the first terminal device, and the first configuration information is used to determine the maximum number of forward link feedback channels that can be simultaneously transmitted by the first terminal device. The maximum number of direct connection feedback channels that can be simultaneously transmitted by the first terminal device is determined by the first terminal device based on the first configuration information. The first terminal device determines the transmission power of the direct connection feedback channels to be transmitted in the case where the number of transmitted direct connection feedback channels is equal to or more than two. Determination the transmission power of the forward connection feedback channels to be transmitted includes uniform distribution by the first terminal device of the transmission power of the forward connection feedback channels to be transmitted according to the maximum transmission power of the first terminal device.
EFFECT: ensuring optimal transmission power.
