Abstract
Aspects of the present disclosure provide a self-contained subframe structure for time division duplex (TDD) carriers. Information transmitted on a TDD carrier may be grouped into subframes, and each subframe can provide communications in both directions (e.g., uplink and downlink) to enable such communications without needing further information in another subframe. In one aspect of the disclosure, a single subframe may include scheduling information, data transmission corresponding to the scheduling information, and acknowledgment packets corresponding to the data transmission. Furthermore, the subframe may additionally include a header and/or a trailer to provide certain bi-directional communications functions.
