The terminal device 11 and the terminal device 12 shown in FIG. 1 communicate with the network device 10, and the terminal device 21 and the terminal device 22 shown in FIG. 1 communicate with the network device 20. The terminal devices can also communicate with each other. For example, the terminal device 11 can communicate with the terminal device 12, the terminal device 11 can communicate with the terminal device 21, and the terminal device 11 can communicate with the terminal device 22. Optionally, when one terminal device communicates with another terminal device, the one or more terminal devices may not communicate with the network device. It can be understood that network devices and terminal devices may also be referred to as communication devices.

The technology described in the embodiments of the present invention can be used in various communication systems, such as 2G, 3G, 4G, 4.5G, 5G communication systems, systems where multiple communication systems are integrated, or future evolution networks.

The threshold Y ₂ may be predefined or configured by the network device.

Through the foregoing embodiments, it is possible to determine whether to perform uplink and side link concurrency according to the adjusted uplink power and side link power, thereby ensuring the performance of the uplink and side link concurrency.

In the foregoing embodiment of the present application, optionally, the terminal U1 may also determine the uplink power and the side link power according to path loss parameters (such as path loss values), where the path loss parameters are the difference between the terminal U1 and the network device. The path loss parameter between the terminal or the path loss parameter between the terminal U1 and the terminal U2.

For example, the terminal U1 uses the path loss parameter between the terminal U1 and the network device to determine the uplink power and the side link power when the uplink data and the side link data are concurrent. When the channel data is not concurrent (it can be understood as only sending uplink data or sending only side link data), the path loss parameter between the terminal U1 and the terminal U2 is used to determine the uplink power or the side link power.

For example, the above priority rule specifies the following information with priority from high to low: downlink control information, information carried by dedicated RRC signaling, information carried by public RRC signaling, system information, and pre-configuration information. The priority rule can also be understood as that downlink control information can overwrite information carried by dedicated RRC signaling, information carried by public RRC signaling, system information, or pre-configuration information, and information carried by dedicated RRC signaling can be Overwrite information, system information, or pre-configuration information carried by public RRC signaling. Information carried by public RRC signaling can overwrite system information or pre-configuration information. System information can overwrite pre-configuration information. Can be called coverage. According to the priority rule in the foregoing example, the terminal U1 may determine that the power difference threshold P _thr is configured or indicated in the higher priority information.

The corresponding relationship may be predefined, or configured or instructed by a network device or other terminal. Optionally, the larger the resource interval Rt, the larger the power difference threshold P _thr corresponding to the resource interval Rt. Optionally, different resource spacing Rt may also correspond to the same power difference threshold P _thr . If the power difference threshold P _thr has a corresponding relationship with the resource interval range where the resource interval Rt is located, the terminal U1 can determine the resource interval range where the resource interval Rt is located, and according to the power difference threshold P _thr and the resource interval range where the resource interval Rt is located The corresponding relationship obtains the power difference threshold P _thr .

The R0, R1, R2, and R3 illustrated in Table 2 respectively represent four resource spacing ranges. The resource interval range where the resource interval Rt is located is Rj among R0, R1, R2, and R3 (j is 0, 1, 2 or 3), and the terminal U1 will obtain the power difference threshold corresponding to the resource interval range Rj
