Data communication

User Equipment, UE, for accessing a Radio Access Network, RAN, comprising at least a central node and a distributed node, the central node controlling the distributed node, wherein the UE comprises:

• at least one processor;
• and
• at least one memory storing instructions that, when executed by the at least one processor, cause the UE at least to:
• establish a connection towards the radio access network;
• receive, from the central node, a UE context modification request comprising:
• a request to change at least part of a lower layer configuration, and
• an identifier related to the request;
• perform the requested change of the lower layer configuration;
• transmit, towards the central node, a confirmation that the requested change has been performed;
• and
• transmit, towards the distributed node, the identifier.

The UE according to any previous claim, wherein the identifier is:

• an identifier for identifying the request;
• a multibit identifier;
• or
• a flag.

A method for a User Equipment, UE, the method comprising causing, at least in part, actions that result in:

• establishing a connection towards a Radio Access Network, RAN, wherein the RAN comprises at least a central node and a distributed node, the central node controlling the distributed node;
• receiving, from the central node, a UE context modification request comprising:
• a request to change at least part of a lower layer configuration, and
• an identifier related to the request;
• performing the requested change of the lower layer configuration;
• transmitting, towards the central node, a confirmation that the requested change has been performed;
• and
• transmitting, towards the distributed node, the identifier.

A distributed node for a Radio Access Network, RAN, comprising at least a central node and the distributed node, the central node controlling the distributed node, wherein the distributed node comprises:

• at least one processor;
• and
• at least one memory storing instructions that, when executed by the at least one processor, cause the distributed node at least to:
• receive a first User Equipment, UE, context modification request transmitted from the central node towards the distributed node, the first UE context modification request comprising:
• a request to change at least part of a lower layer configuration, and
• an identifier related to the request;
• receive a second UE context modification request transmitted from the central node towards the UE via the distributed node, the second UE context modification request comprising:
• a request to change at least part of a lower layer configuration, and
• the identifier;
• transmit the second UE context modification request towards the UE;
• and
• receive, from the UE, the identifier.

A central node for a Radio Access Network, RAN, comprising at least the central node and a distributed node, the central node controlling the distributed node, wherein the central node comprises:

• at least one processor;
• and
• at least one memory storing instructions that, when executed by the at least one processor, cause the distributed node at least to:
• generate an identifier associated with a request to change at least part of a lower layer configuration;
• transmit, towards the distributed node, a first User Equipment, UE, context modification request comprising:
• the request to change at least part of a lower layer, and
• the identifier;
• and
• transmit, towards the UE, a second UE context modification request comprising:
• a request to change at least part of a lower layer configuration, and
• the identifier.
