Method for monitoring channel quality and terminal device

Abstract

The invention provides a method for monitoring channel quality and a terminal device, and the method comprises the steps: receiving a plurality of synchronization signal blocks sent by network equipment through a plurality of channels when the terminal device initially accesses; when the terminal device does not receive the first signaling and the second signaling for monitoring channel quality, determining M synchronization signal blocks from a plurality of synchronization signal blocks received in the initial access process to perform quality monitoring on M channels in one-to-one correspondence with the M synchronization signal blocks, the first signaling carrying at least one SCI-RS resource which is sent periodically for monitoring the channel quality, the second signaling comprisingat least one quasi-co-location QCL information index associated with the control channel demodulation reference signal, the QCL information index being used for determining the reference signal, and the reference signal being used for monitoring the channel quality. According to the method for monitoring the channel quality provided by the embodiment of the invention, the terminal device can determine the reference signal to complete the channel quality monitoring when the terminal device does not receive the signaling sent by the network equipment.

Description

technical field [0001] The present application relates to the communication field, and more specifically, to a method and terminal equipment for monitoring channel quality. Background technique [0002] New Radio (NR) supports high-frequency transmission, which greatly expands the available frequency resources, but the path loss at high frequencies is much more serious than that at low frequencies. Therefore, it is necessary to increase the array gain through beamforming technology to ensure that the cell of coverage. In this case, the robustness (Robust) of the communication system based on beam access needs to be tested. For example, the mismatch between the transmitting and receiving beam pairing between the network device and the terminal device occurs due to the movement or rotation of the terminal device. In some cases, if it cannot be recovered quickly, the transmission of the communication system may be greatly affected or even the connection may be disconnected, an...

In this case, the robustness (Robust) of the communication system based on beam access needs to be tested. For example, the mismatch between the transmitting and receiving beam pairing between the network device and the terminal device occurs due to the movement or rotation of the terminal device. In some cases, if it cannot be recovered quickly, the transmission of the communication system may be greatly affected or even disconnected, and then it is necessary to request the high-level to restore the connection
