A communications method performed by a terminal device, the method comprising: • receiving (S 102) first indication information and second indication information from a network device, wherein the first indication information indicates to the terminal device to send a first signal on a first uplink carrier in a first time period, the second indication information indicates to the terminal device to send a second signal on a second uplink carrier in a second time period, the first time period and the second time period are adjacent in terms of time, and the second signal is a physical uplink shared channel, PUSCH, • determining the first signal to be sent on the first uplink carrier in the first time period based on the first indication information, and determining the second signal to be sent on the second uplink carrier in the second time period based on the second indication information, said method characterised by o when a first reference signal configuration manner is used for the second signal and therefore a priority of the second signal is higher than a priority of the first signal: ▪ determining (S 103) that a symbol in the first signal is to be discarded, and ▪ sending (S 104) the second signal and the symbols of the first signal other than the symbol to be discarded to the network device, o when a second reference signal configuration manner is used for the second signal and therefore the priority of the first signal is higher than the priority of the second signal: ▪ determining (S 103) that a symbol in the second signal is to be discarded, and ▪ sending (S 104) the first signal and the symbols of the second signal other than the symbol to be discarded to the network device. • receiving (S 102) first indication information and second indication information from a network device, wherein the first indication information indicates to the terminal device to send a first signal on a first uplink carrier in a first time period, the second indication information indicates to the terminal device to send a second signal on a second uplink carrier in a second time period, the first time period and the second time period are adjacent in terms of time, and the second signal is a physical uplink shared channel, PUSCH, • determining the first signal to be sent on the first uplink carrier in the first time period based on the first indication information, and determining the second signal to be sent on the second uplink carrier in the second time period based on the second indication information, said method characterised by o when a first reference signal configuration manner is used for the second signal and therefore a priority of the second signal is higher than a priority of the first signal: ▪ determining (S 103) that a symbol in the first signal is to be discarded, and ▪ sending (S 104) the second signal and the symbols of the first signal other than the symbol to be discarded to the network device, o when a second reference signal configuration manner is used for the second signal and therefore the priority of the first signal is higher than the priority of the second signal: ▪ determining (S 103) that a symbol in the second signal is to be discarded, and ▪ sending (S 104) the first signal and the symbols of the second signal other than the symbol to be discarded to the network device. o when a first reference signal configuration manner is used for the second signal and therefore a priority of the second signal is higher than a priority of the first signal: ▪ determining (S 103) that a symbol in the first signal is to be discarded, and ▪ sending (S 104) the second signal and the symbols of the first signal other than the symbol to be discarded to the network device, ▪ determining (S 103) that a symbol in the first signal is to be discarded, and ▪ sending (S 104) the second signal and the symbols of the first signal other than the symbol to be discarded to the network device, o when a second reference signal configuration manner is used for the second signal and therefore the priority of the first signal is higher than the priority of the second signal: ▪ determining (S 103) that a symbol in the second signal is to be discarded, and ▪ sending (S 104) the first signal and the symbols of the second signal other than the symbol to be discarded to the network device. ▪ determining (S 103) that a symbol in the second signal is to be discarded, and ▪ sending (S 104) the first signal and the symbols of the second signal other than the symbol to be discarded to the network device.
