A method for HSPA DL feedback signaling using UL LTE subframes is described. The method includes composing UL feedback signaling for individual ones of a plurality of received DL HSPA carriers, each carrier having an associated carrier index. The UL feedback signaling is composed in accordance with a mapping configured to distribute the UL feedback signaling over a plurality of UL LTE subframes based at least in part on the associated carrier indices. The method also includes transmitting the UL feedback signaling on the plurality of UL LTE subframes. Apparatus and computer readable media are also described.
