DATA TRANSMISSION METHOD, BASE STATION AND USER EQUIPMENT Russian patent published in 2016 - IPC H04W74/08 

FIELD: radio engineering, communication.

SUBSTANCE: embodiments of the present invention provide a data transmission method. According to the embodiments of the present invention, configured resources in the same common E-DCH resource pool can be scheduled for UE of Release 8/9/10/11 at the same time, thereby improving the utilisation ratio of resources at the same time when obtaining the performance gain of TTI alignment. The method includes: obtaining the slot format of a F-DPCH used for UE; receiving the ACK message that is sent by a base station on an AICH; determining the F-DPCH frame offset τ_F-DPCH of the UE and determining a transmission time interval τ_a-m according to a predefined rule, where the τ_a-m indicates the time interval between a starting boundary of an access slot when the UE receives the AICH and the time point when the UE starts uplink transmission; receiving a TPC on the F-DPCH according to the slot format of the F-DPCH and the τ_F-DPCH; and performing uplink transmission to the base station according to the τ_a-m.

EFFECT: improved transmission quality.
