This application discloses a method and an apparatus for determining a data feedback resource. The method includes receiving, by a first terminal, first data sent by a second terminal. The method includes determining a feedback resource of the first data. The feedback resource of the first data is a feedback resource in a feedback resource pool. The method includes sending feedback information of the first data to the second terminal on the feedback resource. The feedback information indicates a receiving status of the first data.

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.

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.

A method includes: receiving, by a terminal, at least one piece of first transmission resource pool configuration information sent by a network device, where the first transmission resource pool configuration information includes at least a first transmission resource pool identifier and first transmission resource pool resource configuration information; when the terminal determines that a first transmission resource pool corresponding to the first transmission resource pool identifier is in a first state, independently selecting, by the terminal, a direct link transmission resource from time-frequency transmission resources corresponding to the first transmission resource pool resource configuration information; and sending, by the terminal, direct link service data by using the direct link transmission resource.

Transmission resource configuration method, apparatus, and system

The present disclosure relates to a method performed by a BS for facilitating IC at a UE and an associated BS. The method includes predefining one or more sets of transmission parameters, where one or more of the transmission parameters in the one or more sets are constrained to take values from respective reduced sets of values out of the values available for the respective one or more transmission parameters, each set of the one or more sets of transmission parameters being identifiable by a unique indication. The method further includes configuring a transmission of the BS, which is to interfere downlink transmissions to the UE from a serving BS of the UE, by using one of the predefined one or more sets of transmission parameters. The present disclosure also relates to a method in a UE for IC and an associated UE.

Interference Cancellation methods used in Base Stations and User Equipments

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.

Resource energy determining method and apparatus

Example scheduling assignment information transmission methods, systems, and devices are described. One example method includes obtaining, by a user equipment (UE), a multiplexing manner used to indicate a relationship between a time-frequency resource for transmitting scheduling assignment information and a time-frequency resource for transmitting data information. The UE receives downlink control information comprising scheduling assignment resource indication information sent by a network device, and obtains, based on the scheduling assignment resource indication information and the multiplexing manner, resource location information occupied to transmit the scheduling assignment information. The UE can then transmit the scheduling assignment information based on the resource location information occupied by the scheduling assignment information.

Scheduling assignment information transmission method and system, and device

Embodiments provide a data exchange method, a terminal device, and a network device. In accordance with the disclosure, a terminal device can obtain resource information for communicating with another terminal device. The resource information can indicate a time-frequency resource and an antenna port corresponding to an antenna polarization direction. The terminal device can then send scheduling information and data information to the another terminal device using the time-frequency resource and the antenna polarization direction. Time-frequency resources and/or antenna polarization directions used by any two terminal devices to send scheduling information and data information to other terminal devices can be different. In this way, terminal devices using different transmit antenna ports can use a same time-frequency resource, and an optional dimension of resource information is increased, thereby increasing an overall system communication capacity.

The method includes: obtaining, by a terminal device, at least one of configuration information of a first resource, configuration information of at least one set of synchronization resources, time domain period information, bitmap information, configuration information of a reserved resource, and configuration information of a time division duplex TDD system; and performing, by the terminal device, the D2D data transmission based on the bitmap information and the second resource. The terminal device may determine the quantity of reserved subframes and the time domain location of the reserved subframe based on information sent by a base station or preconfigured information, and further accurately perform the D2D data transmission by using the second resource based on the bitmap information.
