METHOD AND USER EQUIPMENT FOR TRANSMITTING PHYSICAL UPLINK SHARED CHANNELS

WIPO Patent Application WO/2017/078498

A1

The present disclosure provides a method for transmitting physical uplink shared channels (PUSCHs), including: receiving, by a user equipment (UE), configuration information from a base station, in which configuration information is to configure an operation mode of the UE to operate on shortened subframes; determining, by the UE, a timing relationship from uplink grant (UL Grant) to PUSCH, a timing relationship from physical hybrid automatic retransmission request (ARQ) indicator channel (PHICH) to PUSCH, and a timing relationship from PUSCH to PHICH, and detecting a UL grant and/or a PHICH according to the determined timing relationship; in which the timing relationships are used for transmission of PUSCHs on shortened subframes; and transmitting, by the UE, based on the detected UL Grant and/or the PHICH, data of a PUSCH of a shortened uplink subframe according to the timing relationships determined by the UE in block 302.
