Time-division duplex frame structure for narrowband communications

Abstract:

A method, computer-readable medium, and apparatus are provided. In addition, the apparatus may determine a first set of subframes in the narrowband TDD frame structure used for transmitting a downlink control channel to a UE. In one aspect, a last subframe in the first set of subframes may be subframe n. Further, the apparatus may determine a second set of subframes in the narrowband TDD frame structure used for transmitting a downlink data channel to the UE. In certain aspects, a first subframe in the second set of subframes may be delayed based on k.sub.0 number of subframes after the subframe n. In certain other aspects, a last subframe in the second set of subframes may be subframe n+k.sub.0+x. Additionally, the apparatus may signal first information associated with the k.sub.0 number of subframes to the UE in a first delay field in a DCI transmission.
