Claim:
1. A method for wireless communications, comprising: transmitting a downlink control channel, comprising at least one control channel element (CCE), from a base station to a user equipment (UE) comprising a first antenna and a second antenna for transmitting an acknowledgement (ACK), wherein a first orthogonal resource for transmitting the ACK on a first uplink control channel transmission via the first antenna of the UE is determined based at least in part on a first CCE of the at least one CCE, the first CCE used for transmission of a corresponding downlink control information (DCI) assignment; and signaling a higher layer configuration, from the base station to the UE, that indicates a second orthogonal resource to use for transmitting the ACK on a second uplink control channel transmission via the second antenna of the UE, wherein the first orthogonal resource is different from the second orthogonal resource.
