Problems solved by technology

[0003] In the existing 5G communication system, it is required to support the uplink power control method based on beam pairs, but the flexibility of beam parameter configuration for uplink transmission is higher than that of path loss reference signal parameter configuration for uplink transmission power control, which leads to In an actual communication system, when beam switching occurs, the beam relationship of the path loss reference signal used for uplink transmission power control and the beam relationship of the target uplink transmission cannot be updated synchronously, and the path loss measurement is unreliable, which is not conducive to uplink power control; in addition, due to The configuration of path loss reference signal parameters used for uplink transmission power control is less flexible. When beam switching occurs, frequent RRC reconfiguration (Radio Resource Control Reconfiguration, RRCReconfiguration) is required, which takes a long time to take effect and has huge signaling overhead, which is not conducive to system stability

Abstract

The invention discloses a path loss reference signal indication method and device, a terminal, a base station and a storage medium. The path loss reference signal indication method comprises the following steps: receiving an uplink transmission control signaling sent by the base station; determining an uplink transmission airspace relationship parameter according to the uplink transmission controlsignaling; and determining a path loss reference signal for uplink transmission power control according to the uplink transmission airspace relationship parameter. According to the scheme provided bythe embodiment of the invention, the path loss reference signal is determined according to the spatial domain relationship parameter, the signaling overhead is saved, and the path loss reference signal configuration flexibility of uplink transmission power control is improved.

Description

technical field [0001] Embodiments of the present invention relate to but are not limited to a method and device for indicating a path loss reference signal, a terminal, a base station, and a storage medium. Background technique [0002] The high frequency band with ultra-wide bandwidth (that is, millimeter wave communication) has become an important direction for the development of mobile communication in the future, and has attracted the attention of academic and industrial circles around the world. In particular, the advantages of millimeter waves are becoming more and more attractive in the current increasingly congested spectrum resources and massive access to physical networks. In many standard organizations, such as IEEE (Institute of Electrical and Electronics Engineers, Institute of Electrical and Electronics Engineers ), 3GPP (3rdGeneration Partnership Project, 3rd Generation Partnership Project) have launched corresponding standardization work. For example, in th...
