Abstract
The present invention provides for a method of configuring a physical channel, such as a physical control channel, for device-to-device communication between mobile terminal devices within a cellular communications network environment and comprising a step of locating a device-to-device control channel within a cellular uplink signaling spectrum, and applying a frequency offset parameter to determine separation of the device-to-device control channel from a cellular uplink control channel, and to related terminal devices and computer program products.
Claims2
A method performed by a user equipment (UE) that is configured to communicate, in a direct link with another UE, using a device to device control channel and a device to device shared channel, the method comprising:
- receiving downlink control information including device to device control information including at least one field for indicating a frequency resource assignment;
- determining at least one contiguous resource block for the device to device shared channel, by a resource used for the device to device control channel and the at least one field;
- transmitting the device to device control channel in the resource;
- and
- transmitting the device to device shared channel in the at least one contiguous resource block, wherein the resource and the at least one contiguous resource block are in a subframe.
A user equipment (UE) configured to communicate, in a direct link with another UE, using a device to device control channel and a device to device shared channel, the UE comprising:
- a transceiver configured to receive downlink control information including device to device control information including at least one field for indicating a frequency resource assignment;
- and
- a processor configured to determine at least one contiguous resource block for the device to device shared channel, by a resource used for the device to device control channel and the at least one field,
- wherein the transceiver is configured to:
- transmit the device to device control channel in the resource, and
- transmit the device to device shared channel in the at least one contiguous resource block, wherein the resource and the at least one contiguous resource block are in a subframe.
