Abstract: A data transmission method and a related device. In the method, a first terminal device receives response information based on received DCI that is associated with SSB information and/or a first identity and that is from a network device. In this way, the first terminal device may learn in advance, based on the received DCI, whether to receive response information scheduled by using the DCI. In other words, the first terminal device may identify, based on the DCI, whether a PDSCH scheduled by using the DCI is response information of the first terminal device, thereby avoiding repeated receiving of unnecessary response information, and reducing power consumption of the first terminal device.

Abstract: Embodiments of this application provide a data transmission method, a network device, and a terminal device. The method may include detecting, by a network device, a first signal in an uplink signal. The method may also include determining, by the network device, a signal structure of the uplink signal based on a result of detecting the first signal. Furthermore, the method may include receiving, by the network device, the uplink signal based on the signal structure, and/or responding to the uplink signal based on the signal structure. According to the data transmission method in the embodiments of this application, before receiving data, the network device can determine the signal structure, used by the terminal device, of the uplink signal, and then use a corresponding receiving method to avoid complexity and a reliability risk that are caused by completely blind detection performed by the network device.

Abstract: This application discloses a communication method and a communications apparatus. User equipment transmits uplink data by using a first transmission parameter set when a time interval from a current moment to a latest moment at which uplink timing information is received is less than or equal to a first time interval; or transmits uplink data by using a second transmission parameter set when a time interval from a current moment to a latest moment at which uplink timing information is received is greater than the first time interval, where a transmission parameter included in the first transmission parameter set is different from that included in the second transmission parameter set. Different transmission parameter sets are used to transmit the uplink data at different time intervals based on the time interval from the current moment to the latest moment at which the uplink timing information is received.

Abstract: This application relates to the field of wireless communication technologies. A terminal device receives configuration information, which indicates that one first combination is mapped to a plurality of downlink reference signals, and one first combination is mapped to a plurality of second combinations. The terminal device then determines a mapping relationship between a first combination and downlink reference signals, a mapping relationship between a first combination and second combinations, and a mapping relationship between second combinations and downlink reference signals based on the configuration information. Next, a first preamble is sent on a first RO included in a first combination, and a first uplink reference signal is sent on a first PO included in a second combination. The selected first combination has a mapping relationship with the selected second combination. A selected downlink reference signal group is indicated by the selected first combination.

Abstract: Embodiments of this application provide a synchronization signal block transmission method and a communication apparatus. In an example method, a first synchronization signal block SSB from a network device is received, where the first SSB is a first-type SSB for a first terminal device. If the first SSB is a second-type SSB for a second terminal device, a first control-resource set and/or first common search space is determined based on the first SSB. In the example method, different results may be obtained when the second terminal device and the first terminal device identify a type of the first SSB, and the second terminal device and the first terminal device may use the first SSB in different manners.

Abstract: This application provides a data transmission method and apparatus, to reduce terminal power consumption and ensure transmission reliability during uplink data transmission. The method includes: A terminal transmits first uplink data to a network device on a non-dynamically scheduled resource. The terminal receives response information for the first uplink data from the network device, where the response information is used to indicate whether the first uplink data is successfully received. The response information is further used to indicate whether the terminal monitors a physical downlink control channel PDCCH under a configured condition. If the response information indicates the terminal not to monitor the PDCCH under the configured condition, the response information may be further used to indicate to transmit second uplink data by using the non-dynamically scheduled resource under the configured condition.
