ALLOCATION OF UPLINK CONTROL CHANNEL RESOURCES FROM MAPPED RESOURCE REGION

摘要

For controlling radio transmission in a cellular communication network, a node of the cellular communication network determines a mapping between control channel elements of a downlink control channel and resources of an uplink control channel. The node determines a group of the resources of the uplink control channel which are mapped to a subgroup of the control channel elements. From this group of the resources, the node allocates resources to be used for transmission of uplink control information from a user equipment. Using a radio resource control message, the node may indicate the allocated resources to the user equipment. The allocated resources may be used as a Channel Selection set for transmitting feedback related to a secondary component carrier.

1. A method of controlling radio transmission in a cellular communication network, the method comprising:
a node of the cellular communication network determining a mapping between control channel elements of a downlink control channel and resources of an uplink control channel, the node determining a group of the resources of the uplink control channel which are mapped to a subgroup of the control channel elements; the node allocating, from the group of the resources, resources to be used for transmission of uplink control information from a user equipment; and the node indicating the allocated resources to the user equipment.
