The system upper layer configures a semi-persistent scheduling network identification code SPS C-RNTI (Cell Radio Network Temporary Identifier, cell radio network temporary identity) of the UE. If the high layer starts the semi-static scheduling mode, the downlink control channel transmits the semi-static scheduling starting downlink control information according to the upper layer indication. The semi-persistent scheduling initiation downlink control information is scrambled by the SPS C-RNTI. Accordingly, the higher layer configures a semi-persistent scheduling mode release message, which is still indicated to the UE by the SPS C-RNTI scrambled downlink control information.
On the basis of the above embodiment, the method further includes:
and if the semi-static service transmission fails, authorizing the terminal to retransmit through a downlink control channel.
Specifically, if the transmission of uplink data in the semi-static scheduling mode fails, the base station grants the UE retransmission through the downlink control channel. If the downlink data transmission fails in the semi-static scheduling mode, the UE informs the base station through an uplink control channel, and the base station grants the UE for retransmission through the downlink control channel.
On the basis of the above embodiment, the method further includes:
in the transmission of the semi-static service, a dynamic scheduling mode is adopted for the emergency task, and after the dynamic scheduling is completed, the semi-static service transmission is continued.
Specifically, in the semi-static scheduling transmission of the UE, dynamic scheduling can still be performed, if an emergency task occurs, dynamic scheduling is adopted, and when the dynamic scheduling is finished, the semi-static service transmission is continued in the semi-static scheduling period.
