Abstract

The invention discloses a method and a device for transmitting uplink data and uplink scheduling information. The method for transmitting the uplink data comprises the following steps of: counting an error rate of uplink data sent in a present period by a terminal; judging if the error rate is more than a preset error rate threshold; if yes, setting a transmission parameter by the terminal according to an average transmission rate and a target transmission rate in the present period; if not, judging if the error rates within a continuous appointed quantity of periods including the present period are less than or equal to the error rate threshold; if all the error rates are less than or equal to the error rate threshold, setting the transmission parameter by the terminal according to an average transmission block value and a transmission block threshold within the present period; and performing the following uplink data transmission according to the set transmission parameter. According to the method, the problem of unstable transmission rate of UE (User Equipment) in the prior art is solved, and the size of the transmission block is reduced indirectly by adjusting the transmission parameter, so that the error rate of data transmission is reduced and the data transmission rate is increased.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for transmitting uplink data and uplink scheduling information. Background technique [0002] In the third generation (3rd Generation, referred to as 3G) mobile communication systems, the Universal Mobile Telecommunications System (Universal Mobile Telecommunications System, referred to as UMTS) is one of them, and its network structure consists of a core network (Core Network, referred to as CN), a Universal Mobile Telecommunication System Radio Access Network (UTRAN for short), and a User Equipment (UE for short). Communication between UTRAN and UE is performed through an air interface (Uu interface). [0003] A High Speed ​​Uplink Packet Access (HSUPA for short) function is introduced in the prior art, mainly to support high-speed uplink data services, reduce transmission delay, and increase peak rate. High-Speed ​​Packet Access (HSPA+ for short) is als...
