摘要： A method of securing wireless backhaul for a child base station in a first network provided by a first operator, wherein: any parent base station with wireline backhaul capability and configured to virtualise a core network User Plane Function, UPF, advertises that it supports a wireless backhaul service; the child base station in the first network connects over an air interface to one or more parent base stations in a second network provided by a second operator; the child base station sends a backhaul service request to a connected parent base station; when the backhaul service request is accepted, the connected parent base station uses a virtualised UPF to enable a direct wireline backhaul link between the parent base station and a data network; and the child base station uses the air interface as a wireless backhaul link and the wireline backhaul link of the connected parent base station for backhaul.

摘要： in a scenario where a 5G wireless communication system will have vary wide bandwidth in the extremely high carrier frequency region, more than one channel raster value is employed for wide bandwidth configurations. With this method a terminal can have a coarse initial scan (S101 ) for first synchronisation signals of cells over the whole available bandwidth as a first synchronization step, and obtain necessary information (S102) for a finer resolution scan (S103) to detect a second synchronization signal of a cell in the second synchronization step. Based on the second detection, the terminal can find system information needed to connect to the cell Additionally, different synchronization sequences can be used for different carrier frequencies, hence the design and application of the synchronization sequences can take into account the properties of the carrier frequency such as delay spread and path toss. Frequency division multiplexing can be applied to synchronization sequences of neighbouring cells to avoid Interference,

摘要： A method of generating a device-to-device synchronization signal may include determining a device-to-device identity group. The method may further include determining a device-to-device identity. The device-to-device identity group and the device-to-device identity may together indicate a synchronization source identity. The method may further include generating a secondary device-to-device synchronization signal sequence based on, at least, the device-to-device identity group and a modulo of the device-to-device identity divided by 3. The method may further include transmitting the secondary device-to-device synchronization signal sequence.

摘要： In patchy coverage networks, especially in rural areas, there can be many femto cells (12, 12-1, 12-2) installed in public buildings like pubs, shops, a post office, train station and so on where the coverage is not necessarily contiguous. If a mobile user (1) is running a data application and moving away from the coverage of a serving Femto cell (12), this Femto cell (12) keeps the UE (user equipment) context and buffers the data coming from the network. The UE-ID (or context) is informed to neighbour cells (12-1, 12-2), so that when the UE (1) connects with a neighbour cell (12-1) the buffered data is transferred to the neighbour cell, and the data service can be continued from the point of breakage.

摘要： A method may include allocating transmission resource patterns among multiple terminals. The transmission resource patterns may be associated with vectors from multiple matrices. Each element of the matrices may correspond to a different frequency-domain resource unit and each element position within the vector may correspond to a different time-domain resource unit. Each of the elements may occur at least twice within each matrix of the multiple matrices. Each element of each matrix of the multiple matrices may be unique relative to each other element of the same column of the same matrix and may be unique relative to each other element of the same row of the same matrix.
