Abstract
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.

A method comprising:
- composing uplink feedback signaling for individual ones of a plurality of received downlink high speed packet access carriers, each carrier having an associated carrier index,
- where the uplink feedback signaling is composed in accordance with a mapping configured to distribute the uplink feedback signaling over a plurality of uplink long term evolution subframes based at least in part on the associated carrier indices;
- and
- transmitting the uplink feedback signaling on the plurality of uplink long term evolution subframes.
An apparatus comprising at least one processor;
- and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following:
