METHOD AND DEVICE FOR TRANSMITTING UPLINK DATA IN SUPPORT OF MULTI-SUBFRAME SCHEDULING

摘要

A method for transmitting HARQ for uplink data in support of multi-frame scheduling is provided. The method includes a UE receiving a multi-subframe scheduling uplink grant signaling and PHICH information sent from a base station; for one uplink subframe, the UE processes parameters of uplink transmission according to uplink grant signaling which schedules a SHARQ process of the scheduled uplink subframe and a relative position of a PHICH channel; and the UE sends new uplink data, retransmitting data of the SHARQ to which the uplink subframe belongs, or currently does not send uplink data in the uplink subframe.

1. A method for transmitting Hybrid Automatic Repeat reQuest (HARQ) for uplink data in support of multi-subframe scheduling in a User Equipment (UE), the method comprising:
receiving a multi-subframe scheduling uplink grant signaling and Physical HARQ Indicator CHannel (PHICH) information sent from a base station; determining timing positions of a scheduled uplink subframe and a subsequent transmission of a corresponding Synchronous HARQ (SHARQ) process of the scheduled uplink subframe, according to a timing relationship between the multi-subframe scheduling uplink grant signaling and the scheduled uplink subframe; and for a scheduled uplink subframe, determining parameters of uplink transmission according to uplink grant signaling which schedules a SHARQ process of the scheduled uplink subframe and a relative position of a PHICH channel, and performing data transmission or stopping a current transmission in the uplink subframe according to the parameters of uplink transmission.
