Abstract: Embodiments of the present invention provide an initial access method and apparatus. The method includes: sending, by an access network device, a synchronization signal to user equipment by using at least two downlink beams, where the synchronization signal includes downlink beam indexes of the at least two downlink beams; receiving, by the access network device, a random access preamble sequence sent by the user equipment; and sending, by the access network device, a random access response RAR message to the user equipment by using at least two downlink beams, so that the user equipment completes initial access. In the initial access method provided in the embodiments of the present invention, a disadvantage of channel instability in a high-frequency transmission environment in a new radio system is overcome, to improve initial access performance in the NR system and further improve user experience for the system.

Abstract: A network slice selection method, a radio access device, and a terminal, where the method includes obtaining, by a radio access network (RAN) device, network slice information, sending, by the RAN device, a first message to a terminal, where the first message includes the network slice information, receiving, by the RAN device, a first access request message from the terminal after the terminal selects, based on the network slice information, first attribute information of a first network slice to be accessed by the terminal, and selecting, by the RAN device based on the first attribute information of the first network slice, a second network slice to be accessed by the terminal. The method enables an operator to flexibly configure a network slice, and reduces a communication latency and signaling overheads in a process in which a terminal selects a network slice.

Abstract: A method, system and device for allocating resources of a base station node (Node B) are disclosed to enable F-DPCH resources of a local cell to be sufficiently used. In this invention, Node B reports to the RNC the F-DPCH capability of the local cell so as to provide a decision-making basis about using or not using the F-DPCH to the RNC. If the local cell supports F-DPCH, when the UE initiates an RRC connection establishment request, the RNC instructs the Node B to distribute the F-DPCH and HSDPA resources to the UE, otherwise the RNC instructs the Node B to distribute DPDCH and DPDCCH resources to the UE. The F-DPCH capability of the local cell can be reported in a newly added IE or extended existing IE of the Audit Response message and Resource Status Indication message.

Abstract: Embodiments of the present disclosure provide a resource configuration method and a resource configuration network device. The method includes: obtaining subframe information of each of multiple cells, where the subframe information of each of the multiple cells includes subframe configuration information and flexible subframe resource requirement information of each cell; and determining a flexible subframe resource configuration of each cell according to the subframe information of each of the multiple cells, where the flexible subframe resource configuration of each cell includes that each cell uses one or more of N flexible subframes to perform data transmission. A flexible subframe resource requirement of each of multiple neighboring cells is obtained, and flexible subframe resource configurations of the cells are coordinated in a distributed manner according to a subframe configuration and the flexible subframe resource requirement of each cell, thus, cross-subframe interference that may exist between flexible subframes can be reduced.

Abstract: A method for sending packet data is provided, which includes the following steps. Packet data from a source mobile station (MS) is received. The packet data includes an identity of a destination MS. A routing cache table is searched for a path to the destination MS. An interface is selected if the path to the destination MS is found. The packet data is forwarded through the selected interface according to the found path. Other two methods for sending packet data corresponding to the method for sending packet data as well as an MS and a base station (BS) corresponding to the method for sending packet data are provided. Therefore, link processing can be performed at the MS.
