Abstract: Provided are a method and a device for dynamically constructing a virtual cell. The method includes: a master station sending an event A4 to UE and receiving an A4 measurement report from the UE; and the master station adding a cell corresponding to a cell identity carried in the A4 measurement report as a slave station, herein the master station and slave stations form a first virtual cell. In the technical solution, a serving cell selected by UE may be any cell and is not necessary to be a macro cell, the master station adds a cell which satisfies an event A4 as a slave station and thereby a virtual cell is realized.

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.

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: Disclosed are a retransmission control method and apparatus in a multi-user shared access (MUSA) process, a UE and a storage medium. The method comprises: allocating an MUSA number for a UE (101); receiving an MUSA data packet sent by the UE in an uplink MUSA resource range indicated by a base station (102): using a multi-user shared access radio network temporary identifier (MUSA-RNTI) to indicate a segment of radio resource block used for transmitting acknowledgement information (103); broadcasting the MUSA number of the UE, the data packet of which is correctly received, in the indicated radio resource block, so that the UE determines, according to the MUSA number, whether to retransmit the MUSA data packet which has been sent (104).

Abstract: A method for power control includes: setting a transmission power for a small cell; determining periodically, when the small cell is operated with a low transmission power, whether a Reference Signal Receiving Quality RSRQ value corresponding to a User Equipment UE with worst channel quality in a serving cell is less than a preset RSRQ threshold; and augmenting the transmission power by a step value when the RSRQ value is less than the preset RSRQ threshold.
