Solar atmosphere light

An underwater diving light with efficient waterproof performance includes a top cover, a bottom cover, a light-emitting assembly and a special-shaped light-transmitting seal. A first installation groove is formed in the top cover. A second installation groove is formed in the bottom cover. The special-shaped light-transmitting seal includes a light-transmitting waterproof part, a first installation part and a second installation part. The first installation part, the light-transmitting waterproof part and the second installation part are all annular and connected in sequence. The top cover and the bottom cover are movably connected to form a light housing. The light-emitting assembly is arranged in the light housing. The underwater diving light has the advantages of strong waterproof and moisture-proof performance, diversified luminous forms and a dazzling effect.

The disclosure discloses a handover method based on a cognitive technology. At least two working areas such as a Primary Working Area (PWA) and a Secondary Working Area (SWA), a RRM and a HOC are configured both in User Equipment (UE) and in a Base Station (BS); after receiving a handover request, according to the current radio environments, the PWA of the BS makes a handover negotiation with the neighboring BSs or with the neighboring BSs and the UE requesting handover, determines the communication parameters satisfying the handover request, and sends the determined communication parameters to the SWA of the BS and the SWA of the UE; the SWA of the BS and the SWA of the UE configure said communication parameters and notify the RRM of the BS after the configuration is finished; the RRM of the BS instructs the HOC of the BS and the HOC of the UE to activate the respective SWAs, and to perform the handover according to the communication parameters configured by the SWA. The disclosure also discloses a handover system based on the cognitive technology. The disclosure improves the resource utilization ratio and the quality of service in the current communication system.

The disclosure provides a method and a device for controlling power of a cognitive radio system. The method comprises: measuring a system parameter of a cognitive radio system and a system parameter of a TV system located in an adjacent channel of the cognitive radio system; determining a maximum transmission power of the cognitive radio system according to the system parameter of the cognitive radio system and the system parameter of the TV system; controlling an actual transmission power of the cognitive radio system to be less than the maximum transmission power. In the disclosure, interference to the TV system can be reduced maximally, so that the sensitivity of a receiver inside the TV system is guaranteed.

The present disclosure provides a coordinated scheduling method and system in coordinated multi-point transmission. The method includes: a central control cell of a region determines priorities of users to be scheduled in all coordinated cells according to user information from other coordinated cells in the region; the central control cell schedules users in each coordinated cell according to the determined priorities and informs a corresponding coordinated cell of the information on a user that is finally determined to be scheduled; and after receiving the scheduling information from the central control cell, the corresponding coordinated cell schedules a user in corresponding time and frequency resources. The present disclosure ensures performance of a user with the highest priority, further, considering the performance of the whole system, scheduling is performed in a scheduling stage according to a principle that the subsequent users to be scheduled should cause as little interference on the scheduled users as possible, therefore, the interference between scheduled users is effectively reduced, and the capacity of the system is greatly increased.

The disclosure discloses a method for handover based on a radio resource allocation database. The method includes that the radio resource allocation database is constructed and dynamically maintained; after receiving a handover request from a User Equipment (UE), a Base Station (BS) determines in the database a Radio Access Technology (RAT) and the corresponding carrier frequency resources suitable for a current communication condition of the UE for the UE according to a handover reason in the handover request, and notifies the UE of information regarding the determined RAT and information regarding the corresponding carrier frequency resource; and the UE performs QoS verification on the RAT and the corresponding carrier frequency resources notified by the BS, and switches to the corresponding carrier frequency with the RAT notified by the BS when the QoS on the RAT and the corresponding carrier frequency resources is superior to that of current communication. Meanwhile, the disclosure further discloses a system for handover based on a radio resource allocation database. The disclosure improves a resource usage rate and the QoS of a current communication system. The disclosure enables the UE to complete the handover quickly, such that user experience is improved.

The present invention provides a method and apparatus for multi-user multiplexing. The method includes: a transmission apparatus performing layer mapping on data steams to be transmitted of an open-loop user and a close-loop user respectively; the transmission apparatus performing pre-coding processing on a layer data matrix of the open-loop user and the close-loop user obtained by the layer mapping; and the transmission apparatus mapping the layer data matrix after the pre-coding processing to a plurality of transmission antennas to be sent. The method of the present invention can improve frequency spectrum utilization ratio in the case of the a cell being full load or other possible scenarios, and its performance is better than the multiplexing of two close-loop users who are completely not suitable for pairing. Therefore, the method of the present invention is an optimal scheme adopted in some specified scenarios.
