Method and terminal equipment for monitoring channel quality

Abstract

The present application provides a method for monitoring channel quality and a terminal device. The method includes: when the terminal device initially accesses, receives multiple synchronization signal blocks sent by the network device through multiple channels; When monitoring the first signaling and the second signaling of the channel quality, M synchronization signal blocks are determined from the multiple synchronization signal blocks received in the initial access process, so as to match the M synchronization signal blocks corresponding to the M synchronization signal blocks one-to-one. Channel quality monitoring, the first signaling carries at least one periodic transmission of CSI-RS resources for monitoring channel quality, the second signaling includes at least one quasi-co-located QCL information index associated with the control channel demodulation reference signal, and the QCL information The index is used to determine a reference signal, and the reference signal is used to monitor channel quality. In the method for monitoring channel quality provided in the embodiment of the present application, the terminal device can determine the reference signal to complete channel quality monitoring when no signaling sent by the network device is received.

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
