in response to the user equipment moving to a second cell of the plurality of cells, update the first system information to be associated specifically with the second cell and maintain the second system information; and
permit the user equipment to at least one of acquire other information associated with the first cell based on the first system information and acquire information associated with the plurality of cells based on the second system information.
3. The apparatus according to claim 2 , wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to receive an indication that at least one of the first system information and second system information has changed; and updating the at least one of the first system information and the second system information.
4. The apparatus according to claim 3 , wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to receive said indication on a paging channel.
5. The apparatus according to claims 2 , wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to receive information identifying the plurality of cells associated with the second system information.
6. The apparatus according to claim 5 , wherein said identification information is provided with at least one of the first system information and the second system information.
7. The apparatus according to claim 5 , wherein said identification information comprises an indication that the second system information is associated with all of the cells of a cloud.
8. The apparatus according to claim 5 , wherein said identification information comprises a cell list.
9. The apparatus according to claim 8 , wherein said cell list comprises a list of cell-specific identities.
10. The apparatus according to claim 2 , wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to, in the absence of identification information, determine that the second system information is associated with all of the cells of a cloud.
11. The apparatus according to claim 2 , wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to receive second system information on a first frequency resource, said second system information being provided on the first frequency resource for each cell with which the second system information is associated.
12. The apparatus according to claim 2 , wherein the second system information comprises at least one of cloud identity, system frame number, public land mobile network identity, tracking area identity, cell selection parameters, intra-frequency/inter -frequency/interradio access technology cell reselection parameters and access related information.
13. The apparatus according to claim 2 , wherein at least one of the first and second system information includes periodic system information and scheduled system information.
14. The apparatus according to claim 13 , wherein a master information block and a system information block includes periodic system information and scheduled system information respectively.
15. An apparatus comprising
at least one processor; and
at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
provide first system information and second system information, the first system information associated specifically with the first cell, the second system information associated with each of the plurality of cells, wherein the first system information comprises at least one of downlink bandwidth, physical hybrid-ARQ indicator channel configuration, system frame number, cell identity, cell specific offset of intra frequency cell reselection and scheduling information of the second system information, and
permit a user equipment to at least one of acquire other information associated with the first cell based on the first system information and acquire information associated with the plurality of cells based on the second system information.
16. The apparatus according to claims 15 , wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to send information identifying the plurality of cells associated with the second system information.
17. The apparatus according to claim 15 , wherein the second system information comprises at least one of cloud identity, system frame number, public land mobile network identity, tracking area identity, cell selection parameters, intra-frequency/inter -frequency/interradio access technology cell reselection parameters and access related information.
