According to a sixth aspect of embodiments herein, a computer program comprises instructions, which when executed by a positioning node, cause the network node to perform the method according to the above first aspect.

According to a seventh aspect of embodiments herein, a carrier comprises the computer program according to the above sixth aspect.

According to an eighth aspect of embodiments herein, a computer program comprises instructions, which when executed by a network node, cause the network node to perform the method according to the above third aspect.

According to a ninth aspect of embodiments herein, a carrier comprises the computer program according to the above eighth aspect.

Each carrier mentioned above may be any one of an electronic signal, an optical signal, an electromagnetic signal, a magnetic signal, an electric signal, a radio signal, a microwave signal, or a computer-readable storage medium.

By using the reference signals intended for clock synchronization also for positioning, an advantage is that simultaneous clock synchronization and positioning, based on the same sequences of reference signals, is achieved. A simple solution is therefore provided which does not require transmission of any additional signals exclusively for the positioning as such. The wireless device is a passive receiver node and does not need to transmit any signal, while achieving simultaneous clock synchronization and positioning. The embodiments herein are easy to implement on a network node and/or a wireless device. The embodiments herein can be applied in only a part of network, e.g., which has more severe clock synchronization issues.
