    Abstract: A method and an apparatus for building dynamically a virtual cell are provided. The method includes: a master control site sending an event that signal quality of an adjacent cell of a virtual cell is greater than a first preset threshold or an event that signal level of an adjacent cell of the virtual cell is greater than a second preset threshold to UE, and receiving a measurement report of the event that the signal quality of the adjacent cell of the virtual cell is greater than the first preset threshold or the event that the signal level of the adjacent cell of the virtual cell is greater than the second preset threshold from the UE; and the master control site adding a cell corresponding to a cell identifier carried in the measurement report as a slave site; the master control site and slave sites constitute a first virtual cell.

    Abstract: Disclosed are a key updating method and device, and a master Transmission Point (TP). The method includes: receiving a key parameter for generating a data encryption key of a TP in a virtual cell (S102); and generating the data encryption key of the TP in the virtual cell according to the key parameter and a cell Identity (ID) of the virtual cell (S104). By means of the key updating method and device and the master TP, the problem about key updating of different TPs in a virtual cell is solved.

    Abstract: Provided is a method and apparatus for processing cell interference. The method includes: acquiring spatial beam interference information between each of nodes and a surrounding node of each node; determining an interference management strategy for a service in each node according to the spatial beam interference information and resource allocation information of the surrounding node of each node, wherein the resource allocation information is information for allocating resources of a service in the surrounding node of each node, and the resources are in a time domain, a frequency domain and a space domain; and executing the interference management strategy of the service in each node. The solution above solves the problem that interference management schemes in the related art can only be used independently to manage interference in a time domain, frequency domain or space domain.

    Abstract: The present document discloses a method, apparatus and system for indicating downlink resources of a coordinated multi-point network in an LTE system. The method includes: determining a control station/cell and a service station/cell of a User Equipment (UE); and indicating through signaling that a Physical Downlink Shared Channel (PDSCH) of the UE occupies radio resources of the service station/cell in a control region, whereby a start position of the PDSCH allocated for the UE by the service station/cell is the first symbol of a subframe, and when a resource mapping in the control region is performed, the PDSCH does not occupy Resource Elements (REs) occupied by a Cell Reference Signal (CRS), a Physical Control Format Indicator Channel (PCFICH), a Physical Hybrid-ARQ Indicator Channel (PHICH) of a station/cell where the PDSCH is located, and a Physical Downlink Control Channel PDCCH of the UE.
