Embodiment
[0062] Such as figure 1 As shown, this embodiment provides a method for sending a discovery signal on an unlicensed carrier, including:
[0063] S101: Configure parameters of the discovery signal sent by the access point on the unlicensed carrier;
[0064] The discovery signal is used for coarse synchronization between the access point and the served UE on the unlicensed carrier, as well as measurement and access point discovery. The access point discovery means that the access point sending the discovery signal is detected by the served UE and neighboring access points. Entry point discovery.

The invention discloses a method of sending a finding signal by occupying an unlicensed carrier, a system and an access point. The method comprises steps: parameters of the access point sending a finding signal on an unlicensed carrier is configured; and the access point sends the finding signal on the unlicensed carrier. Time, except for data sending processing, such as for synchronization after the access point seizes resources each time can be reduced, and the spectrum efficiency of the unlicensed carrier is improved.
Description
technical field [0001] The invention relates to the field of wireless communication, in particular to a method, system and access point for sending a discovery signal on an unlicensed carrier. Background technique [0002] LTE-U (LongTermEvolution–Unlicensed, LTE uses unlicensed spectrum) refers to the deployment of LTE in unlicensed spectrum to meet the increasing capacity requirements of LTE systems and improve the efficiency of unlicensed spectrum usage. A possible important evolution direction of communication. When designing LTE-U, it is necessary to consider how to conduct data transmission in a fair and friendly competition with different systems such as WiFi (Wireless Fidelity, wireless fidelity), and LTE-U systems. Influence and preserve LTE technical characteristics. According to the expression of the 3GPP standard meeting, the LTE-U system may also be called LAA (LTE Licensed Assisted Access, LTE Licensed Spectrum Assisted Access) system. At present, there are ...
