DAI designs for FDD carrier aggregation |
| 摘要 |
Certain aspects of the present disclosure relate to techniques for indicating downlink assignments to a user equipment (UE). According to certain aspects, the techniques generally involve generating a downlink assignment index (DAI) indicating a number of assigned downlink transmissions for a user equipment (UE) configured to communicate using multiple component carriers and transmitting a physical downlink control channel (PDCCH) containing the DAI to the user equipment (UE) in a frequency division duplexing (FDD) subframe in which uplink and downlink transmissions may take place at the same time on different carrier frequencies. |

1. A method for wireless communications, comprising:
generating a downlink assignment index (DAI) indicating a number of assigned downlink transmissions on a plurality of component carriers for a user equipment (UE) configured to communicate using multiple component carriers; and transmitting a physical downlink control channel (PDCCH) containing the DAI to the user equipment (UE) in a frequency division duplexing (FDD) subframe in which uplink and downlink transmissions may take place at the same time on different carrier frequencies. |
