1. A method, comprising:
receiving, at a User Equipment (UE), a message regarding a second differentiating factor;
transmitting, by the UE, a first acknowledgement (ACK) or negative acknowledgement (NACK) feedback using a first differentiating factor, wherein the first differentiating factor is determined based on a physical downlink control channel (PDCCH); and
transmitting, by the UE, a second ACK or NACK feedback using the second differentiating factor, wherein the second differentiating factor is a cyclic shift.
