METHOD AND APPARATUS FOR TRANSMITTING HARQ INDICATION INFORMATION |
摘要 |
A method and an apparatus for transmitting Hybrid Automatic Repeat reQuest (HARQ) indication information are provided. The method includes transmitting, by a UE, uplink data on a Physical Uplink Shared CHannel (PUSCH) according to scheduling of a base station; detecting, by the UE, a new UpLink (UL) grant and enhanced Physical HARQ Indication CHannel (ePHICH) information of the base station for the uplink data according to a synchronous HARQ timing relationship, wherein ePHICH resources used for bearing the ePHICH information are mapped to a portion of time-frequency resources of a distributed enhanced Physical Downlink Control CHannel (ePDCCH) set; and if the UL grant is not detected, the UE retransmitting the uplink data or not transmitting the uplink data according to an indication of the ePHICH information. |

1. A method for transmitting Hybrid Automatic Repeat ReQuest (HARQ) indication information, comprising:
transmitting, by a UE, uplink data on a Physical Uplink Shared CHannel (PUSCH) according to scheduling of a base station; detecting, by the UE, a new UpLink (UL) grant and enhanced Physical HARQ Indication CHannel (ePHICH) information of the base station for the uplink data according to a synchronous HARQ timing relationship, wherein ePHICH resources used for bearing the ePHICH information are mapped to a portion of time-frequency resources of a distributed enhanced Physical Downlink Control CHannel (ePDCCH) set; and if the UL grant is not detected, the UE retransmitting the uplink data or suspending transmission of the uplink data according to an indication of the ePHICH information. |
