This application provides a method for transmitting control information and an apparatus. The method includes: When a time domain resource for transmitting first control information on a first PUCCH conflicts in a first time unit with a time domain resource for transmitting a first transport block on a first PUSCH, a terminal device determines, based on a relationship between a payload size of the first control information and a first threshold, a first time domain resource for transmitting the first control information. The first threshold is a maximum quantity of bits of the first control information that can be sent by the terminal device in the first time unit without generating a first result. The first result is that some information bits in the first transport block cannot be transmitted. The terminal device transmits the first control information on the first time domain resource. By using the method, impact of the first control information on transmission of the information bits in the first transport block can be reduced, so that all information bits in a transport block can be transmitted, and transmission performance of the transport block on a PUSCH can be better ensured.
This application provides a system information SI transmission method and apparatus. The method includes: The first terminal device receives a first request message sent by the one or more second terminal devices.

The first terminal device determines N destination identifiers corresponding to the M SIBs or SI messages, where N is an integer greater than or equal to 1, and N≤M. The first terminal device sends, based on the N destination identifiers, the M SIBs or SI messages to the one or more second terminal devices in a broadcast or multicast manner. According to the method, the SI may be transmitted on an SL in the multicast or broadcast manner. This improves SI transmission efficiency and SI update efficiency.

METHOD FOR DETERMINING QUANTITY OF PASSIVE INTERMODULATION SOURCE AND RELATED DEVICE
A method for determining a quantity of passive inter-modulation sources. A quantity of passive inter-modulation sources of a multi-antenna device is obtained. An interference signal that is excited by a sounding signal and that is from a passive inter-modulation source is received. Singular value decomposition is performed on a first matrix corresponding to the interference signal. A quantity of passive inter-modulation sources is determined based on a result of the singular value decomposition. In this way, the quantity of passive inter-modulation sources of the multi-antenna device is directly determined by performing operations including signal receiving and sending and calculation of the multi-antenna device, to implement convenient, accurate, and secure detection of information about the quantity of the passive inter-modulation sources of the multi-antenna device.

The terminal device then determines a mapping relationship between a first combination and downlink reference signals, a mapping relationship between a first combination and second combinations, and a mapping relationship between second combinations and downlink reference signals based on the configuration information. Next, a first preamble is sent on a first RO included in a first combination, and a first uplink reference signal is sent on a first PO included in a second combination. The selected first combination has a mapping relationship with the selected second combination. A selected downlink reference signal group is indicated by the selected first combination.
