Abstract

The embodiment of the invention provides a data transmission method and device, a terminal and network side equipment. The method comprises the following steps: determining that a high layer configures or activates at least two pieces of beam information; receiving a first command, wherein the first command comprises switching indication information; the switching indication information is used for indicating beam information currently used by the terminal in the at least two pieces of beam information; and performing uplink data transmission by using the beam information indicated by the switching indication information at the corresponding transmission opportunity. In the embodiments of the present invention, the terminal can dynamically select or switch among one or more pieces of beam information according to the switching indication information, thereby adapting to continuously changing channel conditions, improving the quality of an uplink, and improving the reliability or throughput of the uplink.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission method, device, terminal and network side equipment. Background technique [0002] In some scenarios, the terminal needs to support eMBB (enhanced Mobile Broadband, enhanced mobile broadband) service and URLLC (Ultra-Reliable Low Latency Communications, low latency and high reliability) service, and the terminal switches a certain beam or certain beams to transmit PUSCH at different times (Physical Uplink Shared Channel, physical uplink shared channel), one or some beams on the base station side can be jointly or independently received, which is meaningful for improving the throughput or reliability of the PUSCH. However, the base station adopts the method of high-level signaling configuration and activation beam information (uplink beam information can usually be represented by spatial relationship information), and it is difficult to control t...
