1. A method implemented in a wireless transmit receive unit (WTRU), the method comprising:
establishing a radio resource control (RRC) connection, wherein the RRC connection is common between at least a first data path associated with a first group of one or more cells and a second data path associated with a second group of one or more cells, and wherein a first signaling radio bearer (SRB) is used for communicating RRC connection information via the first data path;
receiving an RRC reconfiguration message comprising information indicating a configuration associated with a second SRB;
determining that at least part of the configuration associated with the second SRB cannot be successfully applied;
reverting back to a previous RRC connection configuration associated with the second SRB based on determining that at least part of the configuration associated with the second SRB cannot be successfully applied; and
transmitting an RRC message via the first SRB based on determining that at least part of the configuration associated with the second SRB cannot be successfully applied, wherein the RRC message comprises information indicating a cause of failure, and wherein the cause of failure is associated with any of the second SRB and the configuration associated with the second SRB.
