Abstract
A method of wireless communication includes receiving an upper layer configuration of multiple sets of ACK/NAK resources for uplink transmission. The receives resources correspond to at least one secondary downlink component carrier in a multicarrier configuration. The method also includes receiving a physical layer indicator of ACK/NAK resources in the sets.
Claims32
A method of wireless communication, comprising:
- receiving an upper layer configuration of a plurality of sets of ACK/NAK resources for uplink transmission corresponding to at least one secondary downlink component carrier in a multi-carrier configuration, the plurality of sets of ACK/NAK resources being determined based at least in part on a transmission mode of the secondary downlink component carrier;
- receiving a physical layer indicator of ACK/NAK resources in the plurality of sets, the physical layer indicator comprising index for the plurality of sets;
- determining first ACK/NAK resources from the plurality of sets based at least in part on a control channel element (CCE) of the primary component carrier;
- and
- determining second ACK/NAK resources from the plurality of sets based at least in part on an element of each set corresponding to the index.

A method of wireless communication, comprising:
- configuring a plurality of sets of ACK/NAK resources for a user equipment (UE) based at least in part on a transmission mode of a secondary downlink component carrier;
- and
- transmitting a physical layer indicator of ACK/NAK resources in the plurality of sets, the physical layer indicator comprising an index for the plurality of sets, in which:
- first ACK/NAK resources are indicated from the plurality of sets based at least in part on a control channel element (CCE) of the primary component carrier, and
- second ACK/NAK resources are indicated from the plurality of sets based at least in part on an element of each set corresponding to the index.
