Abstract
A user uplink data scheduling method and user equipment, which are applied to multiple-periodicity mode semi-persistent scheduling supporting Transmission Timing Interval (TTI) bundling in the second Downlink/Uplink (DL/UL) timing interval proportion configuration mode (Time Division Duplex (TDD) DL/UL subframe configuration 1) in a Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) TDD system. The user uplink data scheduling method includes the steps of: acquiring an indication message transmitted from a base station for indicating user uplink data based on the multiple-periodicity mode semi-persistent scheduling; setting a periodicity offset of the multiple-periodicity mode semi-persistent scheduling; determining the periodicities of the multiple-periodicity mode semi-persistent scheduling of per two adjacent TTI bundles according to the set offset; scheduling user uplink new transmission packet data according to the determined periodicities of the multiple-periodicity mode semi-persistent scheduling. The problem that the new-transmission packet and the re-transmission packet of the same user of the multiple-periodicity semi-persistent scheduling conflict is so…
