Claim of US Patent No. 10,973,078

1. An apparatus configured to be employed within an evolved Node B (eNodeB), the apparatus comprising:control circuitry configured to
configure a semi-persistent scheduling (SPS) configuration that accommodates short subframes, wherein the short subframes have a transmit time interval (TTI) of less than duration of 1 ms, wherein the SPS configuration comprises:
a short subframe index of a short subframe having short subframe integer values from 0 to M, where M is an integer, wherein the short subframe index corresponds to short subframes having a TTI of less than 1 ms;
provide the SPS configuration within a radio resource control (RRC) signaling;
wherein each short subframe index is unique across short subframe indices within a legacy subframe, wherein a radio frame comprises legacy subframe integer values of the legacy subframe and the short subframe integer values of the short subframe as configured by the SPS configuration, and the short subframe indices repeat from the legacy subframe to another legacy subframe while preserving legacy subframe indices to enable the short subframe to be uniquely identified within the radio frame from among the legacy subframe and the another legacy subframe, and within the legacy subframe, the radio frame comprising a combination of the legacy subframe indices and the short subframe indices.
