Abstract
Embodiments of the disclosure provide a method, an apparatus, a network node, and a computer program product for transmitting D2D synchronization signals. According to the method, D2D synchronization signals are received from a first network node. A hop number of the D2D synchronization signals is determined based on radio resources of the D2D synchronization signals. Whether to transmit the D2D synchronization signals to a second network node is determined based on the hop number.
Claims13
A method for transmitting device-to-device (D2D) synchronization signals, the method comprising:
- receiving a D2D synchronization signal from a first network node on a first subframe with a first subframe offset for a first hop number of the D2D synchronization signal;
- determining a second subframe offset for a second hop number of the D2D synchronization signal;
- and
- transmitting the D2D synchronization signal to a second network node on a second subframe with the second subframe offset.
An apparatus for transmitting device-to-device (D2D) synchronization signals, the apparatus comprising:
- a receiving unit configured to receive a D2D synchronization signal from a first network node on a first subframe with a first subframe offset for a first hop number of the D2D synchronization signal;
- a determining unit configured to determine a second subframe offset for a second hop number of the D2D synchronization signal;
- and
- a transmitting unit configured to transmit the D2D synchronization signal to a second network node on a second subframe with the second subframe offset.
An apparatus for transmitting device-to-device (D2D) synchronization signals, the apparatus comprising:
- at least one processor;
- and
- at least one memory including computer program instructions,
- wherein the at least one memory and computer program instructions are configured to, with the at least one processor, cause the apparatus to:
- receive, via a receiver of the apparatus, a D2D synchronization signal from a first network node on a first subframe with a first subframe offset for a first hop number of the D2D synchronization signal;
- determine a second subframe offset for a second hop number of the D2D synchronization signal;
- and
- transmit, via a transmitter of the apparatus, the D2D synchronization signal to a second network node on a second subframe with the second subframe offset.
