Methods for enabling and handling joint channel estimation and related devices

A method, performed by a second wireless node, for handling joint channel estimation in a time domain in a network, the method comprising:

• obtaining an indication indicating a condition associated with phase continuity and/or power consistency of a transmission between the first wireless node and the second wireless node, wherein the condition is associated with a repeater node enabled to relay the transmission between the first wireless node and the second wireless node, and
• estimating a channel condition of the transmission between the first wireless node and the second wireless node based on the indicated condition.

A method, performed by a repeater node, for enabling joint channel estimation in a time domain in a network, the method comprising:

• receiving, from a first network node, a message indicative of a time duration for which a phase continuity and/or the power consistency is to be maintained by the repeater node, and
• refraining from performing one or more procedures causing phase discontinuity and/or power inconsistency in a transmission between the first wireless node and a second wireless node relayed by the repeater node during the time duration.
