Abstract: Embodiments are disclosed of a hybrid automatic repeat request feedback method and apparatus, and relates to the field of communications technologies. The hybrid automatic repeat request feedback method is applied to a receive end. After receiving data information sent by a transmit end, the receive end may determine, when target data in the data information is not checked, a measurement value of the target data, then generate feedback information based on the measurement value, and subsequently, send the feedback information to the transmit end, so that the transmit end can determine, based on the feedback information, whether the target data needs to be retransmitted.

Abstract: A beam weight obtaining method and an apparatus. An aggregation path is generated by using energy of a plurality of paths to help improve quality of a generated beam, thereby improving an SNR and a capacity of a terminal device. The method includes: a network device obtains a plurality of paths that meet a multipath aggregation condition, where the multipath aggregation condition includes one or more of the following conditions: a condition that every two paths in the plurality of paths need to meet in space, and a condition that every two paths in the plurality of paths need to meet in power. The network device determines aggregation information based on the plurality of paths, where the aggregation information includes information required by the network device to generate an aggregation path corresponding to the plurality of paths.

Abstract: This application provides a communication device, including: a first radio frequency unit, a second radio frequency unit, a switch control unit, and a first signal processing channel. The first signal processing channel includes a first analog-to-digital conversion unit, a first intermediate frequency channel unit, and a first baseband processing unit. The switch control unit is configured to determine, based on resource control information, to connect the first radio frequency unit or the second radio frequency unit to the first signal processing channel. A first radio frequency band in the first radio frequency unit is different from a second radio frequency band in the second radio frequency unit. In this way, different frequency bands may share one radio frequency signal processing channel, thereby optimizing a processing channel, reducing costs, and miniaturizing a communication design.

Abstract: The present disclosure relates to coordinated multipoint wireless communications methods. One example method includes predicting a first delay difference between receiving, by a terminal device, downlink data from a beam A of a first node and receiving, by the terminal device, the downlink data from a beam B of a second node, where the terminal device is located in a coverage area in which the beam A intersects with the beam B, and determining a first adjustment time period based on the first delay difference, where the first adjustment time period is used to adjust a transmission time in which the first node transmits the downlink data to the terminal device by using the beam A.
