A method for scheduling uplink resource, comprising the following steps at a mobile station: receiving uplink single temporary block flow, TBF, resource assignment information sent by a network, wherein the uplink single TBF resource assignment information comprises information of an uplink time slot allocated by the network to a mobile station, and an uplink state flag, USF, corresponding to the uplink time slot, and the information of the uplink time slot comprises information of at least one uplink reduced transmission timing interval, RTTI, time slot pair and information of at least one uplink basic transmission timing interval, BTTI, time slot, wherein scheduling of a BTTI radio block is indicated through a USF corresponding to a downlink RTTI time slot pair in the first 10 ms of a BTTI period and a RTTI radio block is scheduled according to a period of 10 ms, and a BTTI radio block is scheduled according to a period of 20 ms; wherein the downlink time slot is a time slot with a lower sequence number in a downlink RTTI time slot pair corresponding to the uplink RTTI time slot pair, or a time slot with a higher sequence number in a downlink RTTI time slot pair corresponding to the uplink RTTI time slot pair, or all time slots in a downlink RTTI time slot pair corresponding to the uplink RTTI time slot pair; types of the USF comprises a BTTI USF and an RTTI USF; one BTTI USF corresponds to uplink RTTI time slot pair or one uplink BTTI time slot; one RTTI USF corresponds to the uplink RTTI time slot pair or one uplink BTTI time slot; wherein the method further comprises: monitoring the RTTI USF on the downlink RTTI time slot pair corresponding to the uplink RTTI time slot pair; and if the RTTI USF is detected on the downlink RTTI time slot pair corresponding to the uplink RTTI time slot pair in the first 10 ms of the current 20 ms, sending a RTTI radio block on a corresponding uplink RTTI time slot pair and a subsequent uplink RTTI time slot pair in the last 10 ms of the current 20 ms and sending a BTTI radio block on an uplink BTTI time slot in the next 20 ms, wherein the current 20 ms is the 20 ms period during which the USF is detected. receiving uplink single temporary block flow, TBF, resource assignment information sent by a network, wherein the uplink single TBF resource assignment information comprises information of an uplink time slot allocated by the network to a mobile station, and an uplink state flag, USF, corresponding to the uplink time slot, and the information of the uplink time slot comprises information of at least one uplink reduced transmission timing interval, RTTI, time slot pair and information of at least one uplink basic transmission timing interval, BTTI, time slot, wherein scheduling of a BTTI radio block is indicated through a USF corresponding to a downlink RTTI time slot pair in the first 10 ms of a BTTI period and a RTTI radio block is scheduled according to a period of 10 ms, and a BTTI radio block is scheduled according to a period of 20 ms; wherein the downlink time slot is a time slot with a lower sequence number in a downlink RTTI time slot pair corresponding to the uplink RTTI time slot pair, or a time slot with a higher sequence number in a downlink RTTI time slot pair corresponding to the uplink RTTI time slot pair, or all time slots in a downlink RTTI time slot pair corresponding to the uplink RTTI time slot pair; types of the USF comprises a BTTI USF and an RTTI USF; one BTTI USF corresponds to uplink RTTI time slot pair or one uplink BTTI time slot; one RTTI USF corresponds to the uplink RTTI time slot pair or one uplink BTTI time slot; wherein the method further comprises: monitoring the RTTI USF on the downlink RTTI time slot pair corresponding to the uplink RTTI time slot pair; and if the RTTI USF is detected on the downlink RTTI time slot pair corresponding to the uplink RTTI time slot pair in the first 10 ms of the current 20 ms, sending a RTTI radio block on a corresponding uplink RTTI time slot pair and a subsequent uplink RTTI time slot pair in the last 10 ms of the current 20 ms and sending a BTTI radio block on an uplink BTTI time slot in the next 20 ms, wherein the current 20 ms is the 20 ms period during which the USF is detected.
