Apparatuses, methods, and systems are disclosed for receiving selection assistance information corresponding to a preferred network slice. One apparatus includes a processor and a transceiver that receives selection assistance information corresponding to a set of preferred network slices from the mobile communication network, where the selection assistance information includes an indication of at least one preferred network slice starting with a most preferred network slice in a priority order, the selection assistance information further including target cell detection information and/or target cell selection information. The processor performs cell search on a highest priority frequency layer corresponding to the most preferred network slice and selects a cell of the highest priority frequency layer that supports the most preferred network slice based on results of the cell search.

Radio link Failure (RLF) reporting operation in a wireless communication system using multiple cells is disclosed. According to this operation, when a first cell and a second cell are simultaneously connected to a UE and the first cell and the second cell are of different base stations (a first base station and a second base station respectively), if the RLF with the UE on the first cell is detected by the first base station, the first base station may transmits an indication of the RLF with the UE on the first cell to the second base station.

A method and apparatus for transmitting split availability of a cell in a wireless communication system is provided. A first eNodeB (eNB) may transmit a split availability of a first cell, managed by the first eNB, to neighbor eNBs. The split availability of the first cell may indicate whether the first cell supports cell split operation or not. Alternatively, the split availability of the first cell may indicate whether the first eNB supports an active antenna system (AAS).

One embodiment is directed to a master unit for a distributed antenna system (DAS). The master unit comprises one or more donor cards and one or more transport cards, and at least one passive backplane. Each passive backplane comprises a plurality of backplane connectors. Each backplane connector is configured to connect a respective donor card or transport card to the passive backplane. Each backplane connector is connected to each of the other connectors via one or more respective passive bi-directional backplane channels. The master unit is configured so that all active processing of streams of digital samples transported via the DAS is performed by the donor cards and transport cards and not the passive backplane.

The present invention provides methods and apparatus for implementing spatial multiplexing in conjunction with the one or more multiple access protocols during the broadcast of information in a wireless network. One example includes transmitting a first and a second data signal to a remote unit from a respective first and a second spatially separate antenna of a base station so that the first and second data signals have a first spatial configuration, determining that the first and the second data signals are not spatially separated by the remote unit, reconfiguring the (spatial multiplexing logic 104) spatial configuration of the first and second data signals to a second spatial configuration, and transmitting a third and fourth data signal to the remote unit from a second different antenna configuration according to the second spatial configuration.

The present disclosure relates to a system for attempting to establish a connection between a mobile phone and a virtual node of a cellular network. The system includes the virtual node that is configured to be switchable such that the virtual node is switched off and on in a defined manner. The virtual node is configured to automatically change at least one cell parameter each time the virtual node is switched off and on. Further, the present disclosure relates to a method of attempting to establish a connection between a mobile phone and a virtual node of a cellular network.
