FIG. 4 illustrates signalling in accordance with at least some embodiments of the present invention. On the vertical axes are disposed, from the left to the right, network control function 4AA, base station 130, base station 120, and finally UE 110 of FIG. 1, Time advances from the top toward the bottom. While control function 4AA is illustrated as a distinct entity, in some embodiments it may be comprised in a same physical apparatus as base station 120 or base station 130. In other embodiments, control entity 4AA may be comprised in a radio access network controller device, or in a core network device, for example.
In phase 410, UE 110 indicates to the network that it requires low-latency access. This may take place by transmitting a message to such effect to base station 120, which forwards, phase 420, the indication to control function 4AA.
In phase 430, control function 4AA decides on configuring a cluster of cells available to UE 110, to provide a multi-cell access opportunity pattern to UE 110. In the example case of FIG. 4, control function 4AA decides to configure the cells to provide the multi-cell access opportunity pattern to UE 110. The configuring takes place in phase 440, wherein control function 4AA provides configuration information to the cluster of cells. In FIG. 4, the cluster of cells comprises at least one cell controlled by base station 120 and at least one cell controlled by base station 130.
