Claim of US Patent No. 9,603,133

1. A method for configuring uplink control channel resources under a multi-antenna scene, comprising:
receiving, by a terminal equipment provided with multiple antennae, downlink control information carrying acknowledgement
resource indicator (ARI) information, wherein the downlink control information is sent by a network side equipment;

selecting, by the terminal equipment, one or more channel resource groups or one or more channel resources corresponding to
the ARI information out of an initial channel resource set configured by the network side equipment, wherein the initial channel
resource set includes multiple channel resource groups or multiple channel resources; and

determining, by the terminal equipment, the channel resources in the selected channel resource group(s) as uplink control
channel resources for multi-antenna transmission, or determining the selected channel resource(s) and other channel resource(s)
determined by the selected channel resource(s) and one or more offset values as uplink control channel resources for multi-antenna
transmission,

when the terminal equipment cannot use the implicit resource(s) corresponding to the PDCCH CCE or a physical uplink control
channel (PUCCH) format 3 is used to transmit feedback information, the specific size of ARI information is ?log2 N? bits, and different values of the ARI information correspond to respective channel resource groups or respective channel
resources within the initial channel resource set,

wherein N is a number of channel resource groups or channel resources within the initial channel resource set configured b
the network side equipment.
