Abstract
A method and device for processing data in a wireless communication network is provided, where at least two resource pools for an uplink control channel are provided for mobile terminals for a geographical area, and where 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.
Claims17
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 a single uplink control channel from the mobile terminal,
- wherein a resource pool is identified via a sequence group or sequence group hopping pattern, and
- wherein the at least two resource pools comprise:
- a cell-specific uplink control channel resource pool with separate cell-specific uplink control channel resources allocated to different cells, and
- a cooperative multipoint-specific uplink control channel resource pool with common uplink control channel resources allocated to multiple cells,
- performing a switching, by the mobile terminal, between using the cell-specific uplink control channel resource pool and using the cooperative multipoint-specific uplink control channel resource pool in response to a modifier index conveyed in a downlink resource allocation message from said communication network, for the transmission of the single uplink control channel from the mobile terminal;
- wherein the cooperative multipoint-specific uplink control channel resource pool is determined for a geographical area;
- wherein the modifier index in the downlink resource allocation message further enables a modification or shift of an allocated uplink physical resource block.

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:
- configuring a mobile terminal to support at least two uplink control channel resource pools for transmission of a single uplink control channel from the mobile terminal,
- wherein a resource pool is identified via a sequence group or sequence group hopping pattern, and
- wherein the at least two resource pools comprise:
- a cell-specific uplink control channel resource pool with separate cell-specific uplink control channel resources allocated to different cells, and
- a cooperative multipoint-specific uplink control channel resource pool with common uplink control channel resources allocated to multiple cells,
- transmitting to the mobile terminal, a modifier index conveyed in a downlink resource allocation message indicating the mobile terminal to perform a 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 single uplink control channel from the mobile terminal;
- wherein the cooperative multipoint-specific uplink control channel resource pool is determined for a geographical area;
- wherein the modifier index in the downlink resource allocation message further enables a modification or shift of an allocated uplink physical resource block.
