摘要
To establish a multi-AP RRC connection with a user device UD the UD in the coverage area of multiple APs selects suitable ones as cluster set candidates and reports this list to a temporary serving AP the UD chooses. The multi-AP connection itself is setup by the cluster set manager CSM. The CSM collects information from each AP about control channels and load in order to choose which APs will be in the cluster, which will be the serving AP, and to setup the multi-AP connection with the UD. Multiple message exchanges are described for this purpose. Once the multi-AP connection is established, if the UD's connection with the serving AP fails the UD can handover to another AP of the cluster set without having to re-establish a new RRC connection. This is particularly useful for networks subject to severe shadowing effects such as mmWave 5G.
