1. A method of transmission that facilitates erasure detection, comprising:

  • receiving, at an access point, one or more communications from an access terminal;

    estimating, from the one or more communications, one or more attributes associated with the access terminal, wherein the one or more attributes relate to one or both of a size of bandwidth to be assigned to the access terminal and a traffic model of the access terminal;

    assigning an erasure sequence duration for one or more erasure sequences based at least on the one or more attributes, wherein each of the one or more erasure sequences comprises a packet added to a frame by the access terminal for filling in a gap in the frame between data transmissions when the gap is detected by the access terminal, and wherein the packet comprises an identifier known to both the access terminal and the access point; and

    communicating the erasure sequence duration to the access terminal in a message assigning resources to the access terminal, wherein no data transmissions occur with the access terminal during the erasure sequence duration.
