Abstract
In some arrangements, a first network node determines reception timing of a Reference Signal (RS). The RS is transmitted by a second network node at transmission timing. The first network node receives from the second network node the RS according to the reception timing.
Claims20
A wireless communication method, comprising:
- determining, by a first network node comprising a first wireless communication device, reception timing of a Reference Signal (RS) according to at least a time for transmitting a signal between the second network node and a base station in which the second network node is located, wherein the time for transmitting the signal is determined based at least in part on a cell radius of a cell of the base station in which the second network node is located, wherein the RS is transmitted by a second network node at transmission timing, wherein the second network node comprises a second wireless communication device;
- receiving, by the first network node from the second network node, the RS according to the reception timing;
- and
- measuring, by the first network node, the RS to determine interference of the second network node on the first network node.
1 more element
A first network node comprising a first wireless communication device, comprising:
- at least one processor configured to:
- determine reception timing of a Reference Signal (RS), according to at least a time for transmitting a signal between the second network node and a base station in which the second network node is located, wherein the time for transmitting the signal is determined based at least in part on a cell radius of a cell of the base station in a the second network node is located, wherein the RS is transmitted by the second network node at a transmission timing, wherein the second network node comprises a second wireless communication device;
- receive, via a receiver from the second network node, the RS according to the reception timing;
- and
- measure the RS to determine interference of the second network node on the first network node.
2 more elements
A wireless communication method, comprising:
- send, by a second network node comprising a second wireless communication device, a Reference Signal (RS) according to a transmission timing,
- wherein the RS is received by a first network node comprising a first wireless communication device according to a reception timing, and the reception timing is determined by the first network node according to at least a time for transmitting a signal between the second network node and a base station in which the second network node is located, wherein the time for transmitting the signal is determined based at least in part on a cell radius of a cell of the base station in which the second network node is located, wherein the first network node measures the RS to determine interference of the second network node on the first network node.
A second network node comprising a second wireless communication device, comprising:
- at least one processor configured to:
- send, via a transmitter, a Reference Signal (RS) according to a transmission timing,
- wherein the RS is received by a first network node comprising a first wireless communication device according to a reception timing, and the reception timing is determined by the first network node according to at least a time for transmitting a signal between the second network node and a base station in which the second network node is located, wherein the time for transmitting the signal is determined based at least in part on a cell radius of a cell of a base station in which the second network node is located, wherein the first network node measures the RS to determine interference of the second network node on the first network node.
