Abstract:
There is provided methods for use in control signaling in advanced wireless communication systems that support flexible allocation of TDD UL-DL configurations. Where HARQ-ACK bundling is used, PDCCH/EPDCCH transmissions indicating DL SPS release and PDSCH transmissions with corresponding PDCCH/EPDCCH are scheduled only on DL and/or special subframes in a DL association set which are not after the subframe in the DL association set carrying an UL grant. Where HARQ-ACK multiplexing is used, the value of the DL assignment index (VDAIUL) is set to the number of subframes in the DL association set. Cross-subframe scheduling is also used.
