Abstract: The present invention discloses a method and an apparatus for transmitting a signal between user equipments. A quantity of OFDM symbols included in a first subframe sent by a first user equipment to a second user equipment is less than a quantity of OFDM symbols included in a second subframe sent by the first user equipment to a network device, where the second subframe includes 14 OFDM symbols, the first subframe includes 13, 12, or 7 OFDM symbols, and the OFDM symbol includes valid data and a cyclic prefix. In this way, interference between OFDM symbols may be avoided, and performance of a D2D ProSe is improved.

Abstract: A method, a device, and a system for sending and receiving a message for a ProSe. The method includes determining, by a base station, a device identifier list of a ProSe user equipment and a resource parameter that is used by the ProSe user equipment to send a discovery signal; and broadcasting, by the base station, a first indication message, where the first indication message indicates the device identifier list and the resource parameter, so that a first ProSe user equipment performs a ProSe with a second ProSe user equipment. According to the method and the device for sending and receiving a message for a ProSe that are provided by the embodiments, a rate that a ProSe user equipment is sensed can be improved.

Abstract: A method includes: determining, by user equipment UE, a first discovery signal, and obtaining, by the UE after encoding the first discovery signal, respective initial locations of k redundancy versions RVs of the first discovery signal, where k is a positive integer not less than 1. The method also includes separately mapping, by the UE according to respective initial locations off RVs of the k RVs, each RV of the f RVs to at least two physical resource block pairs PRB Pairs of a first resource location, where f is a positive integer not less than 1 and not greater than k. The method also includes transmitting, by the UE at the first resource location, the f RVs of the first discovery signal.
