INFORMATION TRANSMISSION METHOD, DEVICE, AND SYSTEM

摘要

The present invention discloses an information transmission method, a device, and a system, relates to the communications field, and can resolve a problem of inappropriate time-frequency resource allocation in a device-to-device technology. A specific solution is as follows: user equipment obtains discovery information, generates request information according to the discovery information, sends the request information to a base station, receives resource information sent by the base station, and sends the discovery information to other user equipment according to an effective time-frequency resource included in the resource information. The present invention is used for information transmission.

主权项

1. User equipment, applied to a device-to-device technology, comprising: a processor, a memory, a transmitter and a receiver, wherein the processor, the memory, the transmitter, and the receiver are connected to each other;
the processor is configured to obtain discovery information, wherein the discovery information is information that the user equipment needs to send to other user equipment by means of direct communication between devices; the processor is further configured to generate request information according to the discovery information, wherein the request information is used to request a base station to allocate, to the user equipment, a time-frequency resource used to send the discovery information; the transmitter is configured to send the request information generated by the processor to the base station; the receiver is configured to receive resource information sent by the base station, wherein the resource information comprises an effective time-frequency resource, and the effective time-frequency resource is a time-frequency resource that is allocated by the base station to the user equipment and used to send the discovery information; and the transmitter is further configured to send the discovery information to the other user equipment by using the effective time-frequency resource received by the receiver.
