Abstract: Embodiments of the present invention describe a feedback information transmission method and apparatus. The feedback information transmission method may include receiving, by a first terminal, first data sent by a second terminal. The method may also include sending, by the first terminal, feedback information for the first data to the second terminal in a first subframe, where there is second data to be sent by the first terminal in the first subframe. The feedback information may be carried in sidelink control information (SCI) of the second data, or the feedback information may be carried in a data packet carrying the second data. According to the embodiments of the present invention, the feedback information is carried in the SCI or the data packet carrying the second data, so that a peak-to-average power ratio (PAPR) of a system can be reduced.

Abstract: Embodiments of the present disclosure relate to the field of vehicle to vehicle communications technologies, and provide a resource energy determining method and apparatus. An example method includes: obtaining, by first user equipment (UE), time-frequency resource indication information and resource cycle reservation information of second UE in a sensing time window of the first UE; determining, by the first UE, energy of a first resource based on the time-frequency resource indication information of the second UE; and determining, by the first UE, where a time-frequency domain location of the first resource in a transmission period in which the first resource is located is the same as a time-frequency domain location of each of the at least one second resource in a transmission period in which the second resource is located.

Abstract: Embodiments of the present disclosure relate to the communications field, and disclose a method and an apparatus for device-to-device inter-cell interference coordination. The method in the present disclosure includes: receiving, by a first terminal when the first terminal becomes a detection terminal, configuration information sent by a first base station, where the configuration information includes a resource usage detection parameter, and the resource usage detection parameter is used to configure a resource usage detection manner for the first terminal; detecting, by the first terminal based on the resource usage detection parameter, resource usage information corresponding to a resource location; reporting, by the first terminal, the resource usage information to the first base station, so that the first base station adjusts, based on the resource usage information, a D2D data transmission mode for the first terminal or a second terminal using the resource location.

Abstract: An Internet-of-Vehicles communication method and apparatuses are disclosed. The Internet-of-Vehicles communication method may include: sending, by UE, a scheduling request to a base station; receiving, by the UE, notification information sent by the base station for allocating a buffer status report BSR transmission resource; transmitting, by the UE, a BSR on the BSR transmission resource allocated by the base station, where the BSR carries driving status information of the UE, and the driving status information is used by the base station to allocate a radio resource applicable to a current driving status to the UE according to the driving status information; and transmitting, by the UE, data by using the radio resource allocated by the base station.
