Problems solved by technology

However, the network device can configure multiple bandwidth parts (bandwidth part, BWP) for the UE, and can instruct the UE to transmit on different BWPs dynamically through signaling, so that the terminal device uses the same bandwidth part when switching to any BWP. DL RS is used as the path loss estimation of uplink transmission, which makes the path loss estimation error of uplink transmission larger and reduces the system performance

Abstract

The embodiment of the present application discloses a method for power control and a terminal device. The method includes: the terminal device determines a first downlink reference signal resource group corresponding to the first bandwidth part, and the first downlink reference signal resource group At least one downlink reference signal resource is included; the terminal device determines the path loss value used when calculating the transmission power of the uplink data to be transmitted according to the signal corresponding to the downlink reference signal resource in the first downlink reference signal resource group. The method and the terminal device in the embodiments of the present application help to improve system performance.

Description

[0001] This application is filed January 12, 2018, Application No. 201880064135.0, entitled "Method for power control, the terminal device and a network device" Patent Application invention divisional application Technical field [0002] Present application relates to communication field, and more particularly, to a method for power control, terminal equipment and network equipment. Background technique [0003] In the conventional new air interface (New Radio, NR) design, when the user equipment (User Equipment, UE) uplink transmission does not support multi-beam, the network only to the UE is configured with a downlink reference signal (Downlink ReferenceSignal, DL RS ), is used for uplink transmission path loss estimate. However, the network device may be configured to UE more portions of bandwidth (bandwidth part, BWP), and can dynamically instruct the UE via signaling transmission on different BWP, so that the terminal device uses the same switching to any of the BWP a as DL ...
