Abstract: The method includes: A network device sends first configuration information on a first downlink carrier, where the first configuration information indicates a first uplink resource; the network device receives a first signal or first information from the terminal device on the first uplink resource; and when determining, based on the first signal or the first information, that the terminal device accesses the network device on the first downlink carrier, the network device sends a downlink signal on the first downlink carrier. During random access by the terminal device, the network device may configure, for the terminal device, the first uplink resource on which a downlink carrier used to access the network device can be fed back.

Abstract: A method includes: when a band, in which a supplemental uplink (SUL) carrier is located, multiplexes a time-division duplex (TDD) band or a low-frequency frequency-division duplex (FDD) band, M time domain resources used by a terminal device to perform SUL transmission is determined from N time domain resources included in the SUL carrier, and indication information that indicates the M time domain resources is sent to the terminal device such that the terminal device can send an uplink signal and/or an uplink channel using the M time domain resources. Further, a network device may configure an available time domain resource used for uplink transmission for the SUL carrier using a system information block (SIB), Radio Resource Control (RRC) dedicated signaling, or download control information (DCI)/media access control (MAC) control element (CE).

Abstract: According to one embodiment, a terminal device receives downlink control information that is sent by a network device and that indicates a first physical downlink control channel (PUCCH), where the first PUCCH and a second PUCCH occupy a same first time-domain symbol, and the first PUCCH and a third PUCCH occupy a same second time-domain symbol; and the terminal device sends the first PUCCH, where the first PUCCH carries a first sequence and a second sequence, a cyclic shift of the first sequence is determined based on a hybrid automatic repeat request-acknowledgment (HARQ-ACK) value and state information of a scheduling request (SR) corresponding to the second PUCCH, and a cyclic shift of the second sequence is determined based on the HARQ-ACK value and state information of an SR corresponding to the third PUCCH. An HARQ-ACK and a plurality of SRs can be multiplexed on a same PUCCH improving communication efficiency.

Abstract: This application provides a synchronization signal sending method and receiving method, and an apparatus. In the method, a base station determines a frequency domain position of a target frequency resource based on a frequency interval of synchronization channels, wherein the frequency interval of synchronization channels is 2m times a predefined frequency resource of a physical resource block, and m is a preset nonnegative integer. The base station sends a synchronization signal by using the target frequency resource.
