The embodiment of the invention provides an uplink data transmission method and device. The uplink data transmission method comprises the steps of judging whether to-be-transmitted uplink data meet an uplink transmission time sequence; if the to-be-transmitted uplink data do not met the uplink transmission time sequence, stopping transmission of the to-be-transmitted uplink data and setting a BSR (Buffer Size Report) in an effective state; generating new to-be-transmitted uplink data based on uplink authorization of a current sub-frame and sending the new to-be-transmitted uplink data. The new to-be-transmitted uplink data comprises a BSR control element; the current sub-frame represents a sub-frame corresponding to the moment when the to-be-transmitted uplink data do not met the uplink transmission time sequence is detected. The BSR control element is contained in the new to-be-transmitted uplink data, and the new to-be-transmitted uplink data are transmitted, so that a base station can distribute new uplink authorization for a terminal device based on the BSR control element in the new to-be-transmitted uplink data. Therefore, the time delay caused by uplink data transmission failure is reduced.
Description
Technical field [0001] The embodiments of the present invention relate to communication technology, and in particular to a method and device for sending uplink data. Background technique [0002] With the development of communication technology, Long Term Evolution (Long Term Evolution; LTE for short) technology has emerged. It improves and enhances the 3G air access technology, which can provide a higher peak rate, and can provide a downlink 150Mbps\uplink 50Mbps peak rate under a 20M spectrum bandwidth, providing a better user experience. [0003] In the LTE communication system, the uplink transmission timing of the terminal equipment is defined. Taking LTE-Frequency Division Duplex (Frequency Division Duplex; abbreviation: FDD) as an example, an evolved base station (Evolved NodeB; abbreviation: eNB) issues an uplink authorization in n subframes, and the terminal equipment resolves the uplink authorization in n subframes , Prepare data for scheduling. The terminal equipment ...
