1. A method for wireless communication in a system that supports communication using a first duration transmission time interval (TTI) and a second duration TTI that is shorter than the first duration TTI, comprising:
receiving signaling that identifies resources for a control channel associated with the second duration TTI;
receiving a user-specific control message of the control channel within the first duration TTI based at least in part on the signaling, wherein a location of the control channel within the first duration TTI is based at least in part on a location of a data region of the second duration TTI, wherein the first duration TTI and the second duration TTI at least partially overlap in time; and
communicating data using a portion of the resources for the control channel based at least in part on a location of the user-specific control message and a grant received in the user-specific control message.
