The at least one downlink transmission includes a target downlink transmission corresponding to an actual occasion and a pair of a target frequency domain resource and a reference occasion. A location of feedback information corresponding to the target downlink transmission in the codebook corresponds to indication information corresponding to the target downlink transmission. The actual occasion includes a physical downlink control channel (PDCCH) monitoring occasion at which downlink control information (DCI) for scheduling or carrying the target downlink transmission is located or a physical downlink shared channel (PDSCH) reception occasion at which the target downlink transmission is located.

Abstract: A transmitting device and a receiving device are described for a wireless communication system. The transmitting device transmits one or more synchronization signals on a carrier to at least one receiving device. A frequency of a synchronization signal among the one or more synchronization signals is located on a first frequency raster, and a carrier frequency of the carrier is deployed on a second frequency raster. The frequencies of two different synchronization signals among the one or more synchronization signals are located on different frequency positions in the first raster. The transmitting device transmits an indication of the carrier frequency to the at least one receiving device. The indication comprises at least one integer number. The receiving device derives the carrier frequency based on the at least one integer number.

Abstract: A communication method and an apparatus. A first node receives a first message from a second node. The first message indicates a first ratio corresponding to a first downlink reference signal. The first ratio is a power ratio that is between data and a downlink reference signal and is obtained after downlink transmission power adjustment is performed by a parent node. The first node sends a second message to the parent node. The second message includes a first measurement result. The first measurement result is determined based on the first ratio, and the first measurement result is determined based on the first downlink reference signal.

One example method includes detecting DCI in a plurality of time units corresponding to at least one carrier, where a type of the DCI is a first DCI type or a second DCI type, where the first DCI is used to indicate to feed back CBG-level HARQ-ACK information for data scheduled by the first DCI, and where the second DCI is used to indicate to feed back TB-level HARQ-ACK information for data scheduled by the second DCI. A HARQ-ACK feedback codebook is then sent to a network device, where the codebook includes HARQ-ACK information of at least one piece of data scheduled by the DCI, and the HARQ-ACK feedback codebook is determined according to the type of the DCI and a type of the HARQ-ACK feedback codebook.
