WIRELESS COMMUNICATION METHOD AND DEVICE
FIG1 is a schematic diagram of a communications system including a wireless communication method, a network device, and a terminal device according to this application
FIG1 is a schematic diagram of a communications system 100 including a wireless communication method and a device according to this application. As shown in FIG1, the communications system 100 includes a network device 102. The network device 102 may include a plurality of antennas such as antennas 104, 106, 108, 110, 112, and 114. In addition, the network device 102 may include a transmitter chain and a receiver chain. A person of ordinary skill in the art may understand that the transmitter chain and the receiver chain each may include a plurality of components (for example, a processor, a modulator, a multiplexer, a demodulator, a demultiplexer, or an antenna) related to signal sending and receiving. As shown in FIG1, the terminal device 116 communicates with the antennas 112 and 114. The antennas 112 and 114 send information to the terminal device 116 over a forward link 118, and receive information from the terminal device 116 over a reverse link 120. In addition, the terminal device 122 communicates with the antennas 104 and 106. The antennas 104 and 106 send information to the terminal device 122 over a forward link 124, and receive information from the terminal device 122 over a reverse link 126. In addition, the communications system 100 may be a public land mobile network (Public Land Mobile Network, PLMN), a D2D (Device to Device) network, an M2M (Machine to Machine) network, or another network. FIG1 is merely a simplified schematic diagram of an example. The network may further include another network device that is not shown in FIG1.

['3. The method according to claim 1, wherein before the determining, by a network device, a pattern of a phase tracking reference signal based on at least one of a modulation and coding scheme threshold that is corresponding to the pattern of the phase tracking reference signal and requested by a terminal device, a scheduled resource block quantity threshold that is corresponding to the pattern of the phase tracking reference signal and requested by the terminal device, and a factor of impact of phase noise of the terminal device on a signal received by the terminal device and at least one of a modulation and coding scheme currently scheduled by the network device for the terminal device and bandwidth currently scheduled by the network device for the terminal device, the method further comprises: receiving, by the network device, a number of a table of the modulation and coding scheme threshold corresponding to the pattern of the phase tracking reference signal and/or a number of a table of the scheduled resource block quantity threshold corresponding to the pattern of the phase tracking reference signal that are/is sent by the terminal device.']
