Problems solved by technology

For uplink transmission with rank 2 and rank 3, non-coherent codewords cannot support PUSCH to use the rated maximum transmit power
It can be seen that for terminal devices that support partial coherence capability and non-coherent capability, the rated maximum transmission power cannot be used to transmit PUSCH, which makes the transmission quality of PUSCH poor

Abstract

The invention relates to a communication method, device and equipment. The method comprises the steps that terminal equipment determines a first code word set, the first code word set comprises a first code word, the first code word is a 4 * 1 matrix, and each part in the matrix is a non-zero part. In the embodiment of the invention, the first codeword set can comprise the completely coherent codewords, and the terminal equipment sends the uplink data to the network equipment through the completely coherent codewords, so that the power for sending the uplink data can reach the rated maximum sending power, the sending quality of the uplink data is improved, and the sending power utilization rate of the terminal equipment is also improved.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to a communication method, device, and equipment. Background technique [0002] In a wireless communication system, when a terminal device sends an uplink signal, it generates a baseband signal at the baseband. The baseband signal passes through the radio frequency transmission link of the terminal device to obtain a radio frequency signal, and the radio frequency signal is sent out through the antenna of the terminal device. Wherein, the radio frequency link includes a radio frequency integrated circuit, a power amplifier (power amplification, PA) and a duplexer / filter. [0003] Currently, the coherent capability of the terminal device may include: full coherent capability, partial coherent capability and non-coherent capability. Different coherence capabilities characterize the phase alignment between different antenna ports. A terminal ...
