Abstract

A method for processing data in a wireless communication network is provided, wherein at least two resource pools for an uplink control channel are provided for mobile terminals for a geographical area, and wherein the mobile terminals in the geographical area uses at least one of the at least two resource pools for the uplink control channel. In addition, a corresponding device and system are suggested.

First claim

The invention claimed is:

1. A method comprising:
obtaining, by a mobile terminal from a communication network, information indicating that at least two resource pools are provided by the communication network for transmission of an uplink control channel from the mobile terminal in a geographical area in the communication network,
wherein each of the at least two resource pools is identified by
a sequence group or a sequence group hopping pattern, and
a cell identity associated with physical layer transmissions,

wherein the at least two resource pools comprise:
a cell-specific uplink control channel with separate cell-specific uplink control channel resources allocated to different cells, and
a cooperative multipoint-specific uplink control channel with common uplink control channel resources allocated to multiple cells, and

wherein the cell-specific uplink control channel comprises a persistent uplink control channel resource pool and a dynamic uplink control channel resource pool and the cooperative multipoint-specific uplink control channel comprises a persistent uplink control channel resource pool and a dynamic uplink control channel resource pool; and

switching between using the cell-specific uplink control channel resource pool and using the cooperative multipoint-specific uplink control channel resource pool for the transmission of the uplink control channel from the mobile terminal in the geographical area in the communication network.

2. The method according to claim 1 , wherein the geographical area is determined by a cell or by a group of cells.

3. The method according to claim 1 , wherein the at least two resource pools comprise a cooperative multipoint-specific resource pool.

4. The method according to claim 1 , wherein at least one of the two resource pools corresponds to a cell-specific uplink control channel that is derived from system information.

5. The method according to claim 1 , wherein the cooperative multipoint-specific uplink control channel is determined for a geographical area.

6. The method according to claim 1 , wherein uplink control channel blanking is used to free resources for the cooperative multipoint-specific uplink control channel.

7. The method according to claim 1 , wherein a resource pool corresponding to the cooperative multipoint-specific uplink control channel is shared with at least one of the cell-specific uplink control channels.

8. The method according to claim 1 , wherein the mobile terminal is configured to utilize one of the following:
the cell-specific uplink control channel for persistent and dynamic uplink control channel resource pools;
the persistent uplink control channel resource pool of the cell-specific uplink control channel and the dynamic uplink control channel resource pool of the cooperative multipoint-specific uplink control channel;
the persistent and the dynamic uplink control channel resource pool of the cooperative multipoint-specific uplink control channel.

9. The method according to claim 1 comprising applying the at least two resource pools simultaneously or in an alternating order for the transmission of the uplink control channel from the mobile terminal in the geographical area in the communication network.

10. The method according to claim 1 , wherein a modifier index is conveyed in a downlink resource allocation message enabling at least one of:
a modification or shift of an allocated uplink resource;
a switching functionality between a cell-specific resource and a cooperative multipoint-specific resource.

11. The method according to claim 1 , wherein the uplink control channel is a PUCCH.

12. A computer program product embodied on a non-transitory computer-readable medium in which a computer program is stored that, when being executed by a computer, is configured to provide instructions to control or carry out the method of claim 1 .

13. An apparatus comprising at least one processor and at least one memory including computer program code, wherein the at least one memory and the computer code are configured, with the at least one processor, to cause the apparatus to at least perform or control the following:
signaling, to a mobile terminal in a geographical area in a communication network, information indicating that at least two resource pools are provided by the communication network for transmission of an uplink control channel from the mobile terminal,
wherein each of the at least two resource pools is identified by
a sequence group or a sequence group hopping pattern, and
a cell identity associated with physical layer transmissions;

wherein the at least two resource pools comprise:
a cell-specific uplink control channel with separate cell-specific uplink control channel resources allocated to different cells, and
a cooperative multipoint-specific uplink control channel with common uplink control channel resources allocated to multiple cells, and

wherein the cell-specific uplink control channel comprises a persistent uplink control channel resource pool and a dynamic uplink control channel resource pool and the cooperative multipoint-specific uplink control channel comprises a persistent uplink control channel resource pool and a dynamic uplink control channel resource pool, and

switching between using the cell-specific uplink control channel resource pool and using the cooperative multipoint-specific uplink control channel resource pool for the transmission of the uplink control channel from the mobile terminal in the geographical area in the communication network.

14. A wireless communication system with a plurality of devices wherein one of the plurality of devices is the apparatus of claim of claim 13 .

15. An apparatus comprising at least one processor and at least one memory including computer program code, wherein the at least one memory and the computer code are configured, with the at least one processor, to cause the apparatus to at least perform or control the following:
obtaining, by a mobile terminal from a communication network, information indicating at least two resource pools are provided by the communication network for transmission of an uplink control channel from the mobile terminal in a geographical area in the communication network,
wherein each of the at least two resource pools is identified by
a sequence group or a sequence group hopping pattern, and
a cell identity associated with physical layer transmissions;

wherein the at least two resource pools comprise:
a cell-specific uplink control channel with separate cell-specific uplink control channel resources allocated to different cells, and
a cooperative multipoint-specific uplink control channel with common uplink control channel resources allocated to multiple cells, and

wherein the cell-specific uplink control channel comprises a persistent uplink control channel resource pool and a dynamic uplink control channel resource pool and the cooperative multipoint-specific uplink control channel comprises a persistent uplink control channel resource pool and a dynamic uplink control channel resource pool, and
switching between using the cell-specific uplink control channel resource pool and using the cooperative multipoint-specific uplink control channel resource pool for the transmission of the uplink control channel from the mobile terminal in the geographical area in the communication network.

16. A wireless communication system with a plurality of devices wherein one of the plurality of devices is the apparatus of claim of claim 15 .

17. A method comprising:
signaling, to
