[0113] Step S2101 , the network device 102 sends DCI to the terminal 101 .

[0114] In some possible embodiments, the terminal 101 receives the DCI sent by the network device 102 .

[0115] In some possible embodiments, the DCI includes control information for uplink operations of the terminal; the control information includes at least one of the following commands:

[0116] Requesting the terminal to send a positioning reference signal (which may be referred to as a first command);

[0117] Requesting the terminal to report positioning measurement results (may be referred to as a second command); or

[0118] The terminal is required to report information related to environmental measurements (which may be referred to as a third command).

[0119] In one example, the environmental measurement related information includes at least one of the following: a temperature measurement result, a humidity measurement result, and a sample measurement result; the sample may be a sample of at least one chemical substance.

[0120] In some possible embodiments, the control information includes the second command and at least one of the second commands, and the DCI also includes resource scheduling information, and the resources scheduled by the resource scheduling information are used to transmit at least one of the positioning measurement results and the reported environment measurement related information.

[0121] In some possible embodiments, the DCI is scrambled by a terminal-specific RNTI, a group-common RNTI, or a broadcast RNTI.

[0122] In one example, the terminal-specific RNTI is transmitted specifically for a certain terminal, the group-common RNTI is the RNTI common to a group of terminals, and the DCI scrambled with the group-common RNTI is the DCI sent to the group of terminals. The broadcast RNTI can be the RNTI common to all terminals in a cell, or it can be the RNTI defined by the protocol. The DCI scrambled with the broadcast RNTI can be sent to all terminals in the cell.

[0123] In one example, the DCI is scrambled by a terminal-specific RNTI, and the terminal transmits the DCI in a terminal-specific search space; or, the DCI is scrambled by a group-common RNTI or a broadcast RNTI, and the terminal transmits the DCI in a common search space.

[0124] In some possible embodiments, the control information includes at least one of requiring the terminal to report the positioning measurement result and requiring the terminal to report the environment measurement related information, and the DCI also includes resource scheduling information, and the resources scheduled by the resource scheduling information are used to transmit at least one of the positioning measurement result and the reported environment measurement related information.

[0125] In one example, the DCI is a unicast DCI, and the resource is one PUSCH resource; or, the DCI is a multicast DCI, and the resource is a group of PUSCH resources or multiple PUSCH resources.

[0126] In an example, when the DCI is a multicast DCI and the resources are resources of multiple PUSCHs, the terminal 101 may select at least one PUSCH resource according to the terminal identifier.

[0127] In the embodiment of the present disclosure, carrying control information for the uplink operation of the terminal in the DCI can enable the terminal to easily obtain the control information, reduce the complexity of the process for the terminal to obtain the control information, and save energy consumption of the terminal. For example, compared with carrying radio resource control (RRC) layer signaling in the physical downlink shared channel (PDSCH: Physical Downlink Shared Channel, PDSCH) to transmit control commands, the process of the terminal receiving and demodulating PDSCH can be omitted.

[0128] FIG2b is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2b, the embodiment of the present disclosure relates to a communication method, which is used in a communication system 100, and the method includes:
