Description

Power control method and equipment

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a power control method and equipment.

Background

In Release-15 (rel-15) of New Radio, in a Single-transmit-receive node (Single-TRP) transmission scenario, all physical uplink control channel (Physical Uplink Control Channel, PUCCH) resource configuration information of each terminal (e.g. User Equipment (UE)) in Radio resource control (Radio Resource Control, RRC) signaling indication information shares the same set of power control parameters, including a P0 value set, a path loss calculation reference signal set, and a closed loop power control process set; all PUCCH resource configuration information of each UE shares the same set of spatially related information. The association relation between the power control parameter and the space related information is contained in the space related information configuration information.

For one PUCCH transmission, a medium access control unit (Media Access Control Control Element, MAC CE) may activate one of the sets of spatially related information for indicating the transmit beam of the PUCCH. Meanwhile, through the association relation between the space related information and the power control parameters, the power parameters used for actual PUCCH transmission can be obtained.

In a Multi-transmit node (Multi-TRP) transmission scenario, there may be multiple PUCCHs for Acknowledgement/negative Acknowledgement (Negative Acknowledge, NACK) and channel state information (Channel State Information, CSI) information feedback for multiple downlinks. If the PUCCH power control mechanism in the Single-TRP transmission scenario is still used, the PUCCH transmission power may be limited or the transmission power may be too high, which may cause coverage limitation or interference increase, and reduce the downlink transmission rate.
