Title: WIRELESS COMMUNICATION METHOD, TERMINAL DEVICE AND NETWORK DEVICE
Abstract:
Provided are a wireless communication method, a terminal device and a network device, wherein there is a quasi-co-located (QCL) association between demodulation pilot frequencies of control channel candidates in different search intervals and pilot frequency signals of different types, thereby solving the problem of channel estimation during blind detection of a control channel. The method comprises: a terminal device determining a pilot frequency signal corresponding to at least one search interval among a plurality of search intervals of a control channel, wherein there is a quasi-co-located (QCL) association between a pilot frequency signal corresponding to each search interval in at least one search interval and a demodulation pilot frequency of a control channel candidate in each search interval, and the types of pilot frequency signals corresponding to different search intervals among a plurality of search intervals are different; and according to the QCL association between a pilot frequency signal corresponding to each search interval and a demodulation pilot frequency of a control channel candidate in each search interval, the terminal device detecting the control channel candidate in the at least one search interval.
