Method And Apparatus For Enhancing Transmission Of Downlink Ack/Nack Signal
Abstract: The invention relates to a method and apparatus for enhancing transmission of a downlink ACK/NACK signal in an LTE communication system. In order to attain the object of enhancing transmission of a downlink ACK/NACK signal the invention proposes an enhanced design of the current PHICH and thus makes an enhanced PHICH (E PHICH). The enhanced design is focused primarily upon the following aspects: the first aspect is to configure an E PHICH in the legacy PDSCH and to transmit an ACK/NACK signal in the E PHICH so that a UE demodulates the E PHICH to obtain the ACK/NACK signal. The second aspect is to improve a PHICH and PUSCH association design by designing an implicit association between an E PHICH index and a radio frequency resource occupied by a UL grant (in a legacy PDCCH or an E PDCCH) and an explicit association between a PUSCH scheduled by a UL grant and an E PDCCH respectively and to transmit an ACK/NACK signal in the E PHICH so that a UE demodulates the E PHICH to obtain the ACK/NACK signal. With the invention transmission of a downlink ACK/NACK signal in an LTE communication system can be enhanced.
