Patent ID: 8891476

Claim:
A method for resource allocation in a wireless communication system, comprising: identifying, by an apparatus, a set of acknowledgement (ACK)/negative acknowledgement (NACK) resources, wherein the set of ACK/NACK resources corresponds to a resource block comprising a plurality of data symbols and a plurality of demodulation reference signal (DM-RS) symbols; generating a resource grid corresponding to the set of ACK/NACK resources, wherein the resource grid has a first dimension corresponding to one or more cyclic shifts and a second dimension corresponding to a plurality of orthogonal covers, wherein the orthogonal covers correspond to orthogonal sequences used for transmission over the plurality of data symbols; and multiplexing one or more users onto the identified set of ACK/NACK resources at least in part by allocating resources corresponding to respective positions in the resource grid to respective users in the one or more users.
