Abstract

The invention discloses a frequency domain resource indication method and device, and the method comprises the steps: sending downlink control information to a terminal, wherein the downlink control information carries frequency domain resource indication information of L PDSCHs, and L is an integer greater than or equal to 1. According to the frequency domain resource indication method and the frequency domain resource indication equipment provided by the embodiment of the invention, the frequency domain resource indication information of the L PDSCHs is carried in the downlink control information, so the frequency domain resource indication of the PDSCHs in a MultiTRP scene is realized. In addition, according to the embodiment of the invention, the mapping relationship between the plurality of TCI stations activated by the downlink control information and the plurality of PDSCHs is indicated to the terminal.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method and device for indicating frequency domain resources. Background technique [0002] The 5G new air interface will support three major application scenarios, namely enhanced mobile broadband (eMBB), massive machine-type communication (mMTC) and ultra-reliable low-latency communication (URLLC). For URLLC, it is characterized by high reliability and low delay, usually the reliability can be as high as 99.999%, and the delay can be as low as within 1ms. The main applications of URLLC include: industrial application and control, traffic safety and control, remote manufacturing, remote training, remote surgery, etc. For example, the Internet of Vehicles is one of the main applications of URLLC, which has high requirements for the reliability of information transmission. [0003] Currently, in the single transmission point (Single-TRP) working mode, the f...
