摘要： The present disclosure relates to the field of wireless communication technology, and provides a data transmission method and a data transmission device, so as to solve the problem in the related art where, for 5G application scenarios, in the case that an uplink scheduling algorithm for a conventional 4G system continues to be used, a large number of control signaling overheads are required due to the meteoric growth in the number of UEs to be connected. In the present disclosure, a network side device determines non-orthogonal multiple access basic transmission units allocated to UEs, detects a pilot signal from each UE on the corresponding non-orthogonal multiple access basic transmission unit, and in the case that the pilot signal has been detected, performs data detection on the UE which has transmitted the pilot signal through the non-orthogonal multiple access basic transmission unit.

摘要： A wireless network access control method is provided. After an RRC connection is established between a first base station and a UE, a radio bearer for the UE is established in accordance with a service request from the UE. When determining that the UE meets a requirement on communication with second base stations whose types are different from the first base station, a dedicated configuration resource is allocated for the UE for enabling the UE to initiate a dedicated uplink detection signal. Dedicated second base stations are instructed to measure the dedicated uplink detection signal initiated by the UE, and one of the dedicated second base stations is allocated for the UE in accordance with measurement results. The UE is instructed to perform data transmission through the second base station allocated for the UE.

摘要： A dynamic AP grouping method and a dynamic AP grouping device are provided. It is able to provide services to UE in a UE-centered manner as compared with a traditional mode where the services are provided to the UE in a network-centered manner, thereby to prevent the UE from frequently acquiring a network environment, and provide the data transmission service to the UE at a low speed or in a stationary state through APGs. In addition, during the movement of the UE, it is able to transmit the services to the UE through dynamic refresh of APs in the APGs and coordination of the APs in the APG. It is able to reduce the number of handover operations made by the UE, and perform the handover operation in the APG not through a core network, thereby to reduce signaling load of a core network.
