Transmit configuration adaptation for device to device communications based on timing measurements
First Claim
1. A method by a first network node for adapting transmit configuration of a first user equipment, UE, for communications directly to a second UE, the method comprising:
- obtaining a first timing measurement between the first UE and the first network node;
obtaining a second timing measurement between the second UE and a second network node;
adapting the transmit configuration that includes a transmit power level of a wireless communication from the first UE directly to the second UE based on the first timing measurement between the first UE and the first network node and the second timing measurement between the second UE and the second network node; and
transmitting a message containing information instructing the first UE to perform device-to-device direct communications with the second UE using the transmit configuration to control the transmit power level at which the first UE will transmit to the second UE.

Abstract
A method by a first network node is disclosed for adapting transmit configuration of a first user equipment for communications directly to a second UE. The first network node obtains a first timing measurement between the first UE and the first network node. A second timing measurement between the second UE and a second network node is obtained by the first network node. A transmit configuration of a wireless communication from the first UE directly to the second UE is adapted by the first network node based on the first timing measurement and the second timing measurement. Related network nodes, methods by user equipment, and user equipments are disclosed.
