Abstract: Method, apparatus and computer program product able to determining whether a user equipment in a wireless communications network has applied a stored or acquired system information message of a new system information area within a predefined time, where the user equipment replaced a system information message of an initial system information area with a system information message of another system information area or with a cell-specific system information message of another cell. If the new system information area is equivalent to the system information area of the initial system information area, then the system information message for the initial system information area is applied. If the new system information area is different from the system information area of the initial system information area, then a system information message for that different system information area is applied.

Abstract: 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.

Abstract: When a given user equipment (UE) has a plurality K of cells currently serving it, in various embodiments there is an algorithm for triggering the UE to wirelessly send a cell measurement report. The algorithm utilizes a parameter whose value is dependent on the number K of cells currently in the UE's active set. The UE updates K anytime a new cell is added to, or a serving cell is removed from, the UE's active set. In various examples the parameter is an offset that operates such that for adding a new cell increasing values of K make it more difficult to satisfy the algorithm. One example has the offset's value computed using a slope value provided by the network and a default offset value; another has the offset's value computed using maximum and minimum allowable values of both K and the offset which are provided by the network.
