Abstract
There is disclosed a network node for a Radio Access Network, the network node being adapted for communication utilizing a carrier aggregation comprising at least a first carrier and a second carrier. The network node is adapted for transmitting first downlink control information on the first carrier of the carrier aggregation, and second downlink control information on the second carrier of the carrier aggregation, wherein the first downlink control information and the second downlink control information pertain to transmission on the same uplink carrier.
Claims16
A network node for a radio access network, the network node being configured to communicate utilizing a carrier aggregation comprising at least a first carrier and a second carrier, the network node comprising transmitter circuitry and processing circuitry operatively coupled to the transmitter circuitry, whereby the network node is configured to:
- transmit first downlink control information on the first carrier of the carrier aggregation, and second downlink control information on the second carrier of the carrier aggregation, the first downlink control information and the second downlink control information pertaining to transmission on the same uplink carrier and/or to reception on the same downlink receiving carrier.
A method of operating a network node in a radio access network, the network node being configured to communicate utilizing a carrier aggregation comprising at least a first carrier and a second carrier, the method comprising:
- transmitting first downlink control information on the first carrier, and transmitting second downlink control information on the second carrier, the first downlink control information and the second downlink control information pertaining to transmission on the same uplink carrier and/or reception on the same downlink receiving carrier.
A user equipment for a radio access network, the user equipment being configured to communicate utilizing a carrier aggregation comprising at least a first carrier and a second carrier, the user equipment comprising transmitter and receiver circuitry and processing circuitry operatively coupled to the transmitter and receiver circuitry, whereby the user equipment is configured to:
- transmit on an uplink carrier and/or receive on a downlink receiving carrier, based on first downlink control information and/or second downlink control information, the first downlink control information being received on the first carrier and/or the second downlink control information being received on the second carrier, the first downlink control information and the second downlink control information pertain to transmission on the same uplink carrier and/or to reception on the same downlink receiving carrier.
A method of operating a user equipment in a radio access network, the user equipment being configured to communicate utilizing a carrier aggregation comprising at least a first carrier and a second carrier, the method comprising:
- transmitting on an uplink carrier and/or receiving on a downlink receiving carrier, based on first downlink control information and/or second downlink control information, the first downlink control information being received on the first carrier and/or the second downlink control information being received on the second carrier, the first downlink control information and the second downlink control information pertaining to transmission on the same uplink carrier and/or to reception on the same downlink receiving carrier.
