Abstract

The embodiment of the invention provides an uplink data transmission method and device. The method is applied to the electronic equipment. The electronic equipment comprises a wireless transceiver unit and at least two radio frequency units, the radio frequency unit is in communication connection with the wireless transceiver unit. The radio frequency unit comprises an envelope tracking ET power supply module, and the method comprises the following steps: according to a first preset condition, packaging an original uplink data packet into at least two sub-data packets, and respectively sendingthe sub-data packets to at least two radio frequency units of the electronic equipment through a wireless transceiver unit of the electronic equipment; and sending the sub-data packets to a network side in parallel through the radio frequency unit. According to the embodiment of the invention, the problem that the current consumption is difficult to reduce while the data transmission rate is increased in the prior art is solved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to an uplink data transmission method and device. Background technique [0002] With the rapid development of mobile communication technology, there are more and more communication systems, and the complexity of modulation also increases accordingly, which makes the requirements for radio frequency (Radio Frequency, RF) components of electronic equipment more and more stringent. Taking the fifth generation mobile communication technology (5th Generation Mobile Networks, 5G) as an example, the emergence of 5G has brought a qualitative leap in data transmission rate, and the 5G New Radio (NR) frequency band can support 100MHz (megahertz) carrier bandwidth , while specifying a new modulation form that requires extremely low level 2 power level (UE Power Class 2, PC2), error vector magnitude (Error Vector Magnitude, EVM), and a higher peak-to-average ratio (PAPR), a...
