Abstract

The invention discloses a downlink control information transmission method, a terminal device and network equipment. The downlink control information transmission method comprises the following steps: acquiring a plurality of activated transmission configuration indication (TCI) states corresponding to a control resource set (CORESET); according to the activated TCI state of each time frequency resource in the CORESET, receiving downlink control information transmitted on a physical downlink control channel (PDCCH); wherein the activated TCI state of each time frequency resource in the CORESET is determined in the plurality of activated TCI states on the basis of a preset time frequency resource granularity according to a preset rule.

Description

technical field [0001] The present invention relates to the communication field, in particular to a downlink control information method, terminal equipment and network equipment. Background technique [0002] A Physical Downlink Control Channel (PDCCH) is mainly used to transmit network control information, indicating how to transmit downlink or uplink traffic channels. In the New Radio (NR) system, information such as the frequency domain position occupied by the PDCCH in the bandwidth and the number of OFDM symbols occupied in the time domain are encapsulated in the CORESET. The network configures the CORESET resource for the UE and configures the TCI status of the CORESET. To indicate the information of the spatial reception beam corresponding to the CORESET resource. [0003] When the network is configured with multiple transmission nodes (Transmit-Receive Point, TRP), a terminal device (UE, User Equipment) may maintain communication links with multiple TRPs at the same...
