Abstract: 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.

Abstract: This application discloses a communication method and apparatus, to resolve an existing problem that a large quantity of time-frequency resources are occupied for indicating a quantity of repeated transmissions of a Msg 3. The method includes: A terminal device receives first information. The terminal device obtains first indication information based on a shared bit in the first information. The first indication information indicates a quantity of repeated transmissions of a third message Msg 3. The third message Msg 3 is a radio resource control RRC connection request in a random access procedure. The shared bit is shared by the first indication information and the first information. The terminal device determines the quantity of repeated transmissions of the third message based on the first indication information.

Abstract: A signal sending and receiving method and an apparatus is described. The method includes: receiving, by a terminal device, a first downlink signal from a network device in a first time unit of a first carrier, where the first carrier is a TDD carrier; determining, based on the first time unit, a second time unit used to send first feedback information for the first downlink signal on a second carrier, where the second carrier is an FDD uplink carrier; and sending the first feedback information to the network device on the second last symbol and/or the last symbol of the second time unit of the second carrier. Feedback information for a downlink signal on the first carrier is sent on the second carrier, so that a requirement of sending an uplink signal on the first carrier by the terminal device is reduced, thereby improving data transmission efficiency.

Abstract: Embodiments provide a method for generating a random access channel ZC sequence, and an apparatus. A method for generating a random access channel ZC sequence includes: generating, by a base station, notification signaling, where the notification signaling instructs user equipment (UE) to generate a random access ZC sequence by using a second restricted set in a random access set; and sending, by the base station, the notification signaling to the UE, so that the UE generates the random access ZC sequence by using the second restricted set, where the random access set includes an unrestricted set, a first restricted set, and the second restricted set; and the second restricted set is a random access set that the UE needs to use when a Doppler frequency shift of the UE is greater than or equal to a first predetermined value.
