US 2022/0104157 A1 · WIRELESS COMMUNICATION METHOD, NETWORK DEVICE, AND TERMINAL DEVICE

Abstract

Provided are a wireless communication method, a network device, and a terminal device. The network device may indicate a Quasi-Co-Located (QCL) parameter in different indication manners according to whether a Synchronization Signal Block (SSB) is associated with System Information Block 1 (SIB1), which is favorable for ensuring that the terminal device correctly receives QCL indication information. The method includes that: a network device determines SIB1 association indication information of a first SSB, the SIB1 association indication information being configured to indicate whether the first SSB is associated with SIB1; the network device determines whether the first SSB bears indication information of a QCL parameter and/or an indication manner for the QCL parameter in the first SSB based on whether the first SSB is associated with SIB1; and the network device sends the first SSB.
