Abstract: This application provides a feedback information sending method and apparatus and a feedback information receiving method and apparatus. A communications device to which the foregoing methods are applied sends or receives feedback information by using different feedback processes. When a network device does not determine whether a previous piece of feedback information is successfully received, the network device indicates a terminal device to send feedback information of a next piece of downlink data by using a new feedback process, and can schedule the next piece of downlink data without waiting for completion of processing of the previous piece of feedback information, thereby reducing a transmission delay.

Abstract: A signal transmission method and apparatus are described. A network device indicates an uplink transmission resource to a terminal by using first indication information, and the terminal transmits a PUCCH and a first signal on the uplink transmission resource indicated by the first indication information. The uplink transmission resource is within an unlicensed frequency band, and the first signal includes one or more of a PUSCH, an SRS, and a PRACH. Thus, if resources required for PUCCH transmission are fewer than resources included in one interlace in the unlicensed frequency band, a remaining resource in the interlace may be used to transmit the first signal.

Abstract: In this application, a synchronization raster design method and an apparatus are provided. The method includes: A network device determines a first bandwidth. A frequency range corresponding to the first bandwidth is above 52.6 gigahertz GHz. The network device configures a plurality of synchronization rasters in the first bandwidth according to a first rule. One synchronization signal block SSB is placed on each synchronization raster, and each synchronization raster corresponds to one global synchronization number. According to the synchronization raster design method provided in this application, an adaptive first bandwidth can be provided for different subcarrier spacings. This reduces power consumption of the terminal device and improves SSB search efficiency of the terminal device.

Abstract: This application provides a physical downlink control channel transmission method and a related apparatus. The transmission method includes: A network device sends a resource configuration, where the resource configuration indicates a time domain resource used by the network device for PDCCH sending. The network device sends a PDCCH of a first terminal device on a first time domain resource in the time domain resource used by the network device for PDCCH sending, and sends a PDCCH of a second terminal device on a second time domain resource in the time domain resource used by the network device for PDCCH sending. In this way, a terminal device needs to monitor a PDCCH only on a portion of the time domain resource used for PDCCH sending, and an increase in complexity of PDCCH monitoring of the terminal device can also be avoided.

Abstract: A master information block MIB determining method and apparatus are provided. The method is: A network device sends a synchronization information block to a terminal device. At least one field in an MIB included in the synchronization information block is used to indicate whether an MIB is an MIB applied to an unlicensed frequency band. After receiving the synchronization information block from the network device, the terminal device determines, based on the field in the MIB included in the synchronization information block, that the MIB is an MIB applied to the unlicensed frequency band. In this way, the terminal device can determine, based on the at least one field in the MIB in the synchronization information block, whether the received MIB is an MIB applied to the unlicensed frequency band, to accurately access a corresponding cell subsequently.
