Abstract
A method is disclosed—for a wireless communication device served by a network access node—of keeping a time reference at the wireless communication device. The wireless communication device is configured for operation according to at least first and second operational modes, the second operational mode having lower power consumption than the first operational mode. The method comprises (during operation according to the first operational mode) determining (for the second operational mode) desired timings of timing signals to be transmitted from the network access node, and transmitting a request signal to the network access node, wherein the request signal carries information of the desired timings of timing signals to be transmitted from the network access node. In some embodiments, the method further comprises receiving a response signal from the network access node, wherein the response signal carries information of actual timings of timing signals to be transmitted from the network access node. Corresponding method for a network access node, apparatuses, wireless communication device, network access node and computer program product are also disclosed.
