A method including determining, by a first terminal device, a size of a sidelink data packet, determining, by the first terminal device based on the size of the sidelink data packet, a first quantity of time-frequency units corresponding to the sidelink data packet, determining, by the first terminal device, a frequency domain resource of a second time-frequency resource from a first time-frequency resource, based on the first quantity, a resource selection rule, and at least one of a time domain resource of the second time-frequency resource, or a frequency domain resource of the second time-frequency resource, and performing, by the first terminal device, at least one of sending the sidelink data packet to a second terminal device on the second time-frequency resource, or receiving the sidelink data packet from a second terminal device on the second time-frequency resource.

Sidelink data packet sending and receiving method and communication apparatus

Embodiments of this application disclose a relay communication method and a communications apparatus, and relate to the field of communications technologies, to resolve a problem that communications system performance is unable to be met because remote UE selects relay UE to forward data in existing relay communication. The method includes a network device obtains a measurement report that includes signal quality of a sidelink (sidelink, SL) between first user equipment and at least one second user equipment and a radio network identifier of the at least one second user equipment. The network device selects target relay user equipment, of the first user equipment, from the at least one second user equipment based on the measurement report and selection assistance information associated with each second user equipment.

Relay communication method and communications apparatus

A communication method includes: a first terminal device receives a first message from a network device. The first message includes first information and second information, the first information is used to indicate a first search space, the second information is used to indicate a first cooperation group identifier, and a first cooperation group includes the first terminal device and a second terminal device. The first terminal device obtains first control information from the first search space based on the first information and the second information. The first control information is used to schedule downlink data of the second terminal device.

Communication method and communication apparatus

This application discloses a communication method and apparatus. The communication method and apparatus are applicable to an Internet of Vehicles, or are applicable to fields such as D2D, intelligent driving, and intelligent network connected vehicles. The method includes: A network apparatus determines an isidelink transmission resource of an icooperation terminal apparatus, where the icooperation terminal apparatus belongs to N cooperation terminals, the isidelink transmission resource belongs to the 1sidelink transmission resource to an Nsidelink transmission resource, the isidelink transmission resource is different from a jsidelink transmission resource, the jsidelink transmission resource is a sidelink transmission resource that is of a jcooperation terminal apparatus and that is determined by the network apparatus, the isidelink transmission resource is used by the icooperation terminal apparatus to send second data to a target terminal apparatus, the second data is determined based on first data sent by the network apparatus to the icooperation terminal apparatus, and the N cooperation terminal apparatuses and the target terminal apparatus belong to a same cooperative transmission group. The network apparatus sends the isidelink transmission resource to the icooperation terminal apparatus and the target terminal apparatus.

Communication method and apparatus

A first terminal device obtains first data from a network device based on a first identifier, where the first identifier is used to identify a first cooperation group, and the first cooperation group includes the first terminal device and a second terminal device. The first terminal device forwards the first data to the second terminal device.

Implementing data scrambling transmission during user cooperation transmission

The present disclosure discloses an example communication method and apparatus. One example communication method includes receiving, by a first node, decoding information and coded data from a second node, where the coded data is obtained after data of a node group in which the first node is located is encoded, the data of the node group includes data expected to be received by at least two nodes in the node group, and the at least two nodes include the first node. Data expected to be received by the first node is obtained by the first node based on the decoding information and the coded data.

This application provides a method for wireless communication and an apparatus. The method includes: receiving, by a communication device, L pieces of first data, and determining reception statuses for the L pieces of first data; receiving, by the communication device, second data, and generating feedback information based on the reception statuses for the L pieces of first data and the second data, where the feedback information indicates one or more reception statuses for M pieces of first data, the M pieces of first data are included in the L pieces of first data; and the second data is data obtained after N pieces of first data are encoded, the N pieces of first data are included in the L pieces of first data; and sending, by the communication device, the feedback information.
