    Abstract: Provided is a radio access network slice construction method and apparatus applied to a master base station. The method includes: constructing, by each of the master base station and at least one neighboring secondary base station in the RAN, a network slice end-to-end correspondence with a core network, and determining RAN slices information in the master base station and the neighboring secondary base station; collecting statistics, by the master base station, on Slice IDs or MDD information reported by all UEs served by the master base station, and obtaining quantity of slice resources needed to be allocated to construct RAN slices by the master base station; transmitting, by the master base station, reconstruction request information of a RAN slice to the neighboring secondary base station; and performing, by the master base station, multi-connection data transmission reconfiguration on the UEs served by the master base station through an RRC message.

    Abstract: Described are methods, systems and devices for eliminating redundant retransmissions in radio link layer (RLC) acknowledged mode (AM) data transmissions and receptions. In some embodiments, when an RLC service data unit (SDU) has not been completely received, the value of a state variable may be selectively set based on whether or not a contiguous set of byte segments of the RLC SDU have been received. This prevents the retransmission of byte segments that are either currently being transmitted or have not yet been transmitted. In other embodiments, the selective setting of the state variable may be triggered by the expiration of a reassembly timer. The described implementations may improve the data transmission of RLC SDUs in high data rate scenarios, which may be ubiquitous in 5G implementations.

    Abstract: Provided is a data packet transmission method and device. The method includes: generating, by a first network element, first indication information according to a delivery status fed back by a second network element to the first network element, where the first indication information is used for instructing the second network element which has not successfully sent a data packet to a terminal to discard the data packet indicated by the first indication information. The present disclosure may solve the problem in the related art of unsynchronized data transmission in sending of a data packet to a terminal by a plurality of second network elements.

    Abstract: Methods and devices for reporting and issuing a band extension capability are provided. A terminal side receives terminal capability query information from a network side, determines band interval lists to which each band supported by the terminal side belongs, and reports the supported bands through cells corresponding to the band interval lists to which each band belongs; and the network side determines band interval lists to which each band supported by the network side belongs when issuing a band capability supported by the network side, and issues the supported bands through cells corresponding to the band interval lists to which each band belongs. By the solutions of the disclosure, the bands belonging to different band interval lists can be reported and issued through different cells, and the problem of limitations to the number of the bands during the reporting and issuing of the bands is solved.

    Abstract: The disclosure discloses an authentication method and system for a wireless mesh network. The method comprises: when a new node accesses a network and the node is a Mesh Point (MP), the MP selects one authenticated node from neighbor nodes as a father node, and a uniquely identified secure path exists between the father node and an AC; the MP uses the father node as an authentication point to perform authentication; and after being transmitted to the AC through the secure path between the father node and the AC, which then forwards an authentication message to an AS; similarly, a return message of the AS is forwarded by the AC to the father node through the secure path, and the MP is authenticated. The authentication message is saved on the AC at the same time, so as to facilitate the second authentication of the MP.
