Abstract
According to an aspect, there is disclosed a method that includes aligning, by a radio access network node wirelessly connected to at least two parent nodes and to a child node, an uplink reception timing associated with the child node with a downlink reception timing associated with a parent node of the at least two parent nodes.
Claims16
A method comprising:
- aligning, with a radio access network node wirelessly connected to at least two parent nodes and to a child node, an uplink reception timing associated with the child node with a downlink reception timing associated with a parent node of the at least two parent nodes;
- maintaining, with the radio access network node, a single downlink reception timing associated with the at least two parent nodes;
- indicating, with the radio access network node, to each parent node of the at least two parent nodes whether the parent node is a reference parent node or a secondary parent node;
- and
- indicating, with the radio access network node, the secondary parent node about timing transitions compared to the reference parent node and about a downlink reception timing difference to enable the secondary parent node to derive timing gaps at the radio access network node to guarantee the single downlink reception timing at the radio access network node.

A radio access network node wirelessly connected to at least two parent nodes and to a child node, the radio access network node comprising:
- at least one processor;
- and
- at least one non-transitory memory including computer program code;
- the at least one memory and the computer program code being configured to, with the at least one processor, cause the radio access network node to at least perform:
- aligning an uplink reception timing associated with the child node with a downlink reception timing associated a parent node of with the at least two parent nodes;
- wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the radio access network node to at least perform:
- maintaining a single downlink reception timing associated with the at least two parent nodes;
- wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the radio access network node to at least perform:
- indicating to each parent node of the at least two parent nodes whether the parent node is a reference parent node or a secondary parent node;
- and
- indicating the secondary parent node about timing transitions compared to the reference parent node and about a downlink reception timing difference to enable the secondary parent node to derive timing gaps at the radio access network node to guarantee the single downlink reception timing at the radio access network node.
