Communications method, terminal device and network device

A communication method, comprising:

• receiving, by a network device, a predetermined uplink sequence transmitted by a terminal device, the uplink sequence being used for indicating that the terminal device has a demand for determining a target network device;
• determining, by the network device, to transmit a first downlink message to the terminal device according to the uplink sequence, wherein when the network device determines that the target network device is a first network device according to location information of the terminal device, the first downlink message being used for identifying the first network device;
• and
• transmitting, by the network device, the first downlink message, to enable the terminal device to determine that the target network device is the first network device according to the first downlink message;
• wherein, when the network device determines that the terminal device needs to measure a downlink reference signal, the first downlink message is used for instructing the terminal device to measure the downlink reference signal transmitted by each second network device of a plurality of second network devices.

A terminal device, comprising a processor, a transceiver and a memory, the memory is arranged to store instructions, the processor is arranged to execute the instructions stored in the memory to control the transceiver to receive or transmit signals, wherein:

• the transceiver is arranged to transmit a predetermined uplink sequence, the uplink sequence being used for indicating that the terminal device has a demand for determining a target network device;
• the transceiver is further arranged to receive a first downlink message transmitted by a network system according to the uplink sequence;
• and
• the processor is arranged to execute the instructions stored in the memory to execute the following operation:
• when the first downlink message is used for identifying a first network device, determine that the target network device is the first network device according to the first downlink message, wherein the first network device is determined by the network system according to location information of the terminal device;
• wherein, when the first downlink message is used for instructing the terminal device to measure a downlink reference signal transmitted by each second network device of a plurality of second network devices in the network system,
• the processor is specifically arranged to determine the target network device by measuring the downlink reference signal transmitted by the each second network device.
