Abstract
The present invention provides a method of determining a transmission power for device to device, D2D, transmissions between a first user equipment device and a second user equipment device using transmission resources being used for transmissions to a cellular network entity by a third user equipment device, the method comprising determining a measure of a path loss between the cellular network entity and the first user equipment device, and using the measure of the path loss to determine a maximum transmission power such that the D2D transmissions are received at the cellular network entity with a signal level around or below a noise level.
Claims6
A method of determining a transmission power for device to device, D2D, transmissions between a first user equipment device and a second user equipment device using transmission resources being used for transmissions to a cellular network entity by a third user equipment device, the method comprising:
- determining a measure of a path loss from the cellular network entity to the first user equipment device,
- using the measure of the path loss to determine a maximum transmission power such that the D2D transmissions are received at the cellular network entity with a signal level around or below a noise level,
- wherein the determining of the maximum transmission power includes using a correction value for compensating for a difference between the measured path loss from the cellular network entity to the first user equipment device and a path loss from the first user equipment device to the cellular network entity.
