Abstract: Communication methods and apparatuses are provided. In an example method, a terminal device receives first indication information from a network device, where the first indication information indicates a first physical uplink control channel (PUCCH) resource set; and the terminal device determines the first PUCCH resource set based on the first indication information. The first PUCCH resource set is different from a second PUCCH resource set, or the first PUCCH resource set is partially the same as a second PUCCH resource set. The first PUCCH resource set is configured for a first-type terminal device, while the second PUCCH resource set is configured for a second-type terminal device. A maximum bandwidth supported by the first-type terminal device is less than a maximum bandwidth supported by the second-type terminal device.

Abstract: This application provides an uplink signal sending method, an apparatus, and a system, and generally relates to the field of communications technologies. The uplink signal sending method includes obtaining first indication information, and determining, based on the first indication information, whether to send an uplink signal on a supplementary uplink (SUL) or an uplink (UL). The first indication information is used to indicate a SUL available time, and the SUL available time is a time in which an uplink signal can be sent on an SUL carrier in a preset period. The method is applied to a procedure in which an uplink signal is sent by using an uplink carrier, to improve flexibility in an uplink signal sending process.

Abstract: A data transmission method and apparatus are provided. The method includes: A terminal device determines a first frequency band, receives first information from a network device, where the first information is used to indicate a first transmission frequency band, determines the first transmission frequency band based on the first information, and transmits data to the network device in the first transmission frequency band. A bandwidth of the first frequency band is greater than a maximum channel bandwidth supported by the terminal device. The first transmission frequency band is used by the terminal device to transmit data. The first frequency band includes the first transmission frequency band. In this way, the network device can dynamically schedule a terminal device with a low bandwidth capability within a larger frequency resource range, thereby obtaining a larger frequency selective scheduling gain and improving data transmission efficiency.

Abstract: A signal sending method, a signal receiving method, and a device. The signal sending method includes: generating synchronization signals, where the synchronization signals include a first synchronization signal and a second synchronization signal; and sending the synchronization signals, where the first synchronization signal and the second synchronization signal overlap in time domain, and within a time domain resource in which the first synchronization signal and the second synchronization signal overlap, there is an intersection set between a frequency domain resource corresponding to the first synchronization signal and a frequency domain resource corresponding to the second synchronization signal. In this way, frequency domain resources occupied by the synchronization signals may be reduced, thereby saving frequency domain resources for another data transmission process. In addition, the two synchronization signals may further share a part of the frequency domain resources, thereby improving resource utilization.

Abstract: A link detection method and an apparatus are provided. The link detection method includes: determining that a first radio link to an access network device fails; detecting a second radio link to the access network device, to determine whether the second radio link fails; and if determining that the second radio link does not fail, communicating with the access network device over the second radio link. If it is determined that the first radio link fails, the second radio link may be further detected. If the second radio link does not fail, the second radio link may continue to be used in communication, and RRC reestablishment does not need to be performed on the first radio link. This reduces an unnecessary RRC reestablishment process, and a terminal device does not need to fall back to an RRC idle state, so that the terminal device can continue to work normally.
