Abstract: Embodiments of the present disclosure disclose a resource selection method and an apparatus, which are applied to the communications field, and can resolve a collision problem occurring, and improve transmit quality of a discovery signal of a terminal. The method comprises: obtaining, by the terminal, a transmit probability of a discovery signal, where the transmit probability is a probability that the terminal starts to transmit the discovery signal on a predetermined discovery frame by using a discovery resource pool; generating, by the terminal, an indication signal corresponding to the transmit probability; and if the indication signal is a transmit indication signal, starting to transmit, by the terminal, the discovery signal on the predetermined discovery frame by using the discovery resource pool. The present disclosure is applicable to frequency-time resource selection by a terminal for transmitting a discovery signal.

Abstract: The present invention provides a method for sending a discovery signal and user equipment. The method comprises determining a frequency-time position with a frequency-time hopping invariant according to the frequency-time hopping invariant, determining an initial frequency-time position of a discovery signal in an initial discovery frame according to the frequency-time position with the frequency-time hopping invariant and an idle frequency-time position in the initial discovery frame, and sending the discovery signal at the initial frequency-time position. The method comprises determining a second frequency-time position of the discovery signal in a next discovery frame following the current discovery frame, and sending the discovery signal at the second frequency-time position.

Abstract: Embodiments of the present invention relate to the field of communications, and provide a method and a device for transmitting data by using a multidimensional constellation diagram, which can further improve bit error rate-signal to noise ratio performance by means of a multidimensional constellation diagram. The method is: First, bit data is mapped, by using an n-dimensional constellation diagram, into a column vector including n real numbers, then the n real numbers included in the column vector are modulated by using a resource element and sent, and after demodulating the n real numbers from a received signal, a receiving device finds, in the n-dimensional constellation diagram, a constellation point with coordinate values having a closest Euclidean distance to a point with coordinates being the n real numbers, and finally maps the coordinate values of the constellation point back into the bit data.

Abstract: A communication method, a base station, and a terminal, which are applied to the communications field, to resolve a problem in the prior art that the terminal cannot obtain a frequency-time pattern of a discovery time period when an interval between two consecutive discovery time periods is long. The method includes: generating, by a base station, an identifier of a current discovery frame of a current discovery time period; and broadcasting, by the base station, the identifier of the current discovery frame of the current discovery time period, so that a terminal that receives the broadcast sent by the base station acquires, according to the identifier, in the broadcast, of the current discovery frame of the current discovery time period, a frequency-time pattern of the current discovery time period or a frequency-time pattern of a discovery time period that is after the current discovery time period.
