Abstract
It is determined that there are X uplink control channel resources available for uplink signaling. Each of those X uplink control channel resources are sub-channelized into a plurality of sub-channels that each defines a unique time instant or point in time. For each of Y units of control information there is selected a unique combination of one of the sub-channels and a modulation (X and Y are each integers greater than one). The Y units of control information are sent on the X uplink control channel resources according to the respectively selected combinations. By example the uplink resources may be an ACK/NAK/DTX bit on a PUCCH. In one example the sub-channels are individual slots of a PUCCH. In another example the sub-channels are the reference-signal part and the data part of a single PUCCH slot.
