Providing neighbor cell transmission information in a long-term evolution single frequency network
View Patent ↗A system for providing control channel information is provided. The system comprises a processor programmed to promote transmission of a multicast control channel (MCCH). The MCCH includes information related to a service notifying user equipment when transmission on a resource is blocked by one or more cells within a plurality of cells. The MCCH further includes information notifying user equipment when the service is transmitted at less than full power by one or more of the cells of the plurality of cells.
1. A system for providing control channel information to communicate services to user equipment, comprising:
a processor programmed such that a transmission is made of a multicast control channel (MCCH) including information related to a multimedia broadcast multicast services (MBMS) service, wherein the transmission specifies whether one or more neighboring cells within a plurality of cells are transmitting one or more signals of the MBMS service at reduced power.
2. The system of claim 1 , wherein reduced power includes when transmission of the MBMS service on a corresponding resource of the one or more neighboring cells is restricted by a certain power offset.
3. The system of claim 2 , wherein the corresponding resource is further defined as an OFDM (orthogonal frequency division multiplexing) resource.
4. The system of claim 2 , wherein reduced power includes transmission at a low power.
5. The system of claim 1 , further comprising:
user equipment using the MCCH information for signal reception.
6. The system of claim 1 , wherein the MCCH further including information notifying user equipment when transmission on a resource is promoted by one or more neighboring cells within the plurality of cells.
7. The system of claim 1 , wherein the MCCH further includes a cell identification of those cells that the transmission on a resource is blocked by one or more cells within the plurality of cells.
8. The system of claim 1 , wherein the MCCH further includes a cell identification of those neighboring cells that a transmission power on a corresponding resource is reduced including a power offset information.
9. The system of claim 1 , wherein the MCCH further includes information notifying user equipment when transmission of the MBMS service on a corresponding resource is blocked by the one or more cells.
10. The system of claim 9 , wherein blocking includes where a cell does not transmit the MBMS service on the corresponding resource.
11. The system of claim 1 , wherein the processor is a processor of an enhanced node B of a cell of the plurality of cells of a telecommunications network, and wherein the system further includes:
a central control of the telecommunications network where a first cell of the plurality of cells transmits a first service on a first resource, a neighboring second cell has no user equipment interested in the first service, the central control configured such that the processor of the enhanced node B promotes transmission of the MCCH including information related to the MBMS service notifying user equipment in the telecommunications network that the transmission was blocked in the neighboring second cell.
12. The system of claim 1 , wherein the processor is a processor of an enhanced node B of a cell of the plurality of cells of a telecommunications network, and wherein the system further includes:
a central control of the telecommunications network, the central control configured such that the processor of the enhanced node B promotes transmission of the MCCH including information notifying user equipment that the MBMS service is transmitted at less than full power by one of the cells of the telecommunications network.
13. The system of claim 1 , wherein the MCCH further includes information specifying whether the one or more neighboring cells are transmitting signals at full power, reduced power, or no power.
14. A method for providing control information, comprising:
transmitting, by a device, a multicast control channel (MCCH) comprising information notifying user equipment when one or more neighboring cells are transmitting signals related to a multimedia broadcast multicast services (MBMS) service at reduced power.
15. The method of claim 14 , wherein the MCCH further comprises information notifying user equipment when transmission on a resource is promoted by the one or more neighboring cells.
16. The method of claim 15 , wherein the resource is further defined as an OFDM (orthogonal frequency division multiplexing) resource.
17. The method of claim 14 , further comprising:
user equipment using the MCCH information for signal reception.
18. The method of claim 14 , wherein the MCCH further includes a cell identification of those cells that transmission on a resource is blocked by the one or more neighboring cells.
19. The method of claim 14 , wherein the MCCH further includes a cell identification of those cells that a transmission power on a resource is reduced and a power offset information related to the transmission power reduction.
20. The method of claim 14 , wherein transmitting at reduced power prevents signal overlap on a resource between the neighboring cells.
21. The method of claim 14 further comprising transmitting different services on a resource in the neighboring cells.
22. The method of claim 21 wherein a LTE device does not transmit on the resource.
23. The method of claim 14 further comprising:
transmitting a first service on a first resource by a LTE device;
identifying that no user equipment interested in the first service is present in a neighboring cell;
notifying the LTE device by a central control that the first resource is blocked in the neighboring cell.
24. The method of claim 14 further comprising:
transmitting a first service on a first resource by a LTE device;
notifying the LTE device by a central control that a second service is transmitted on the first resource at reduced power in a neighboring cell.
25. The system of claim 14 , wherein the MCCH further comprises information specifying an amount by which power is reduced.
26. A system for providing control channel information, comprising:
a processor programmed to promote transmission of a multicast control channel (MCCH) including information related to a service notifying user equipment when transmission on a resource is blocked by one or more cells within a plurality of cells, the MCCH further including information notifying user equipment when the service is transmitted at less than full power by one or more of the cells of the plurality of cells, wherein the processor is a processor of an enhanced node B of a cell of the plurality of cells of a telecommunications network, and
a central control of the telecommunications network where a first cell of the plurality of cells transmits a first service on a first resource, a neighboring second cell has no user equipment interested in the first service, the central control configured such that the processor of the enhanced node B promotes transmission of the MCCH including the information related to the service notifying user equipment in the telecommunications network that the transmission was blocked in the second cell.
