Abstract
Embodiments of this application disclose power control method, a terminal device, and a network device. The method includes: determining, by a terminal device, a first downlink reference signal (DL RS) resource group corresponding to a first bandwidth part (BWP), where the first DL RS resource group includes at least one DL RS resource; and determining, by the terminal device according to a signal corresponding to the at least DL RS resource in the first DL RS resource group, a path loss value used to calculate a transmit power for to-be-transmitted uplink data. The method, the terminal device, and the network device of the embodiments of this application help to improve system performance.
Claims14
A power control method, applied in a system comprising a plurality of bandwidth parts (BWPs), comprising:
- receiving, by a terminal device, second information sent by a network device, wherein the second information is used to indicate a mapping relationship between a BWP and a downlink reference signal (DL RS) resource group, and in the mapping relationship, one DL RS resource group is configured for each BWP;
- determining, by the terminal device, a first DL RS resource group corresponding to a first BWP according to the mapping relationship, wherein the first DL RS resource group comprises at least one DL RS resource;
- and
- determining, by the terminal device according to a signal corresponding to the at least one DL RS resource in the first DL RS resource group, a path loss estimation used to determine a transmit power for transmitting uplink data to be transmitted.
A terminal device, applied in a system comprising a plurality of bandwidth parts (BWPs), comprising:
- a processor;
- memory for storing instructions executable by the processor;
- wherein the processor is configured to:
- receive second information sent by a network device, wherein the second information is used to indicate a mapping relationship between a BWP and a downlink reference signal (DL RS) resource group, and in the mapping relationship, one DL RS resource group is configured for each BWP;
- determine a first DL RS resource group corresponding to a first BWP according to the mapping relationship, wherein the first DL RS resource group comprises at least one DL RS resource;
- and
- determine, according to a signal corresponding to the at least one DL RS resource in the first DL RS resource group, a path loss estimation used to determine a transmit power for transmitting uplink data to be transmitted.
