Title:
TRANSMISSION OF UPLINK CONTROL CHANNELS TO MULTIPLE NODES
Document Type and Number:
WIPO Patent Application WO/2014/075043
Kind Code:
A3
Abstract:
Uplink control channel management is disclosed in which a user equipment, UE, receives a configuration for multiple uplink control channels for transmission to multiple nodes (Node A, Node B) in multiflow communication with the UE. The UE generates the uplink control channels (PUCCHl, PUCCH2) based on the configuration, wherein each of the uplink control channels is generated for a corresponding one of the nodes. The UE then transmits each of the uplink control channels (PUCCHl, PUCCH2) to the corresponding node (Node A, Node B). For UEs capable of multiple uplink transmissions, in which the UE communicates with at least one of the nodes over multiple component carriers, the configuration may designate the component carrier for the transmission of the uplink control channel for that node. For UEs capable of only single uplink transmissions, the configuration may designate the transmission of the uplink control channels in either frequency division multiplex, FDM, or time division multiplex, TDM, schemes.
