Problems solved by technology

If the multiplexing mode and rate matching information of the two are directly determined without considering the beam coordination problem, the signal cannot reach the receiving end due to the inconsistent understanding of the beam by both the base station and the terminal.
For example, the transmission beams of PUSCH and PUCCH are inconsistent. The base station and the terminal agree that when the PUCCH and PUSCH are transmitted in the same slot, the control information included in the PUCCH needs to be transmitted in the PUSCH, and the transmission beam of the PUSCH is uniformly used for transmission on the PUSCH channel. Data and control information included in PUCCH, but because the terminal has not received the scheduling information of PUSCH, the terminal will continue to use the original PUCCH transmit beam to send signals on PUCCH, and the base station has adjusted its receive beam to align with the PUSCH transmit beam. It will cause the signal sent by the terminal through the PUCCH to be unable to reach the base station
[0004] For the problems of beam update, multiplexing, and rate matching between the first signal and the second signal when the beams are inconsistent, no effective solution has been proposed so far

Abstract

The application discloses a signal transmission method and device. The method includes the following steps: determining a first signal transmission mode; and transmitting a first signal by using the determined transmission mode. The scheme of the application ensures that both a base station and a terminal have a consistent understanding of beams and finally enables the signal to reach an oppositeterminal.

Description

technical field [0001] The present invention relates to the communication field, in particular to a signal transmission method and device. Background technique [0002] Discussions on NR are ongoing, and an important application scenario for NR is the high-frequency beam transmission technology, especially the transmission technology based on radio frequency beams. Due to the high directivity of the beams, there is a problem when the two beams are not aligned. [0003] In a time slot (slot), when the first uplink signal and the second uplink signal need to be transmitted simultaneously, the problem of beam coordination between the two needs to be considered. If the multiplexing mode and rate matching information of the two are directly determined without considering the beam coordination problem, the signal cannot reach the receiving end due to the inconsistent understanding of the beam by both the base station and the terminal. For example, the transmission beams of PUSCH...
