摘要： The present invention discloses a terminal device, a network device, and a data transmission method, and relates to the communications field, so as to resolve a problem of relatively low transmission efficiency that is caused by transmission resource collision. A specific solution is as follows: A sending unit sends, by using a first resource block, a first MAC PDU that carries a first reservation indicator field used to instruct to reserve the first resource block; a receiving unit receives a second MAC PDU sent by using a second resource block by a set of second terminal devices, where the second MAC PDU carries a first resource feedback field used to indicate that the first resource block is successfully reserved; a determining unit determines, according to the first resource feedback field that is received by the receiving unit and that is sent by a second terminal device in the set of second terminal devices, that the first resource block is a resource block used to send a new MAC PDU; and the sending unit sends the new MAC PDU by using the first resource block determined by the determining unit. The present invention is applied to a data transmission process.

摘要： Embodiments of the present invention provide a resource processing method, an apparatus, and a terminal. The method includes: receiving, by a first terminal, a first message simultaneously sent by each of at least one second terminal, where the first message is carried on N resources and used to indicate location information of resources on which to-be-sent data is located, and N is a positive integer greater than or equal to 2; and determining, by the first terminal based on the location information of the resources on which the to-be-sent data is located, resources used by the first terminal to send data. Because the first message is carried on the N resources, a probability of collision of the resources used by the second terminal to send the first message is very low. On this basis, the first terminal easily learns the resources determined by the second terminal, and therefore can accurately determine, based on the resources determined by the second terminal, the resources used by the first terminal to send the data. This further avoids collision between the resources used by the first terminal to send the data and the resources used by the second terminal to send the to-be-sent data, and improves reliability of a V2X system.

摘要： A multicast transmission method is disclosed. A base station of a first cell obtains first multicast resource information of at least one second cell, where the base station of the first cell is different from a base station of each second cell; and the base station of the first cell sends second multicast resource information to user equipment, where the second multicast resource information is used to indicate a resource configuration used by each second cell to transmit multicast service data. The base station of the first cell actively sends obtained multicast resource information to the user equipment in a broadcast manner. In this way, the base station of the first cell does not need to configure, in a unicast manner for each user equipment, a resource location for sending/reading the multicast service data of each second cell, thereby reducing signaling overheads.

摘要： Embodiments of the present invention provide a data transmission method and apparatus, and relate to the communications field. The method includes: obtaining configuration information; establishing at least one logical channel according to an identifier of each logical channel and the corresponding transmission mode indication that are in the configuration information; obtaining a transmission resource according to the transmission mode indication of a logical channel to which device-to-device (D2D) buffered data belongs; and sending the D2D buffered data by using the obtained transmission resource, where a logical channel having a first transmission mode indication uses a centralized resource allocation mode, and a logical channel having a second transmission mode indication uses a distributed resource allocation mode. According to the embodiments of the present invention, a problem that a resource allocation mode used by a terminal during D2D communication is relatively single and is not flexible enough is resolved, and the terminal can use different resource allocation modes according to a logical channel granularity, so that not only consumption of signaling resources of a network device can be reduced, but also QoS requirements of some services that require relatively high quality of service (QoS) can be satisfied.
