A method and radio network controller (RNC) in a radio access network (RAN) for controlling access to a cellular telecommunication system. Upon receiving an access request from a given user equipment (UE) through a given radio base station (RBS), the RNC retrieves authorization information from an access control database within the RAN. The authorization information indicates whether the given UE is authorized to access the system through the given RBS. The RNC alternatively grants access or denies access to the UE based on the retrieved authorization information. The RBS is particularly useful for controlling access through small cells with limited capacity.

The disclosure is related to selecting an operating channel for a cellular network to reduce interference to a wireless local area network (WLAN) operated by a small cell comprising a WLAN access point and a cellular network modem. The small cell performs a channel scan of available channels, determines whether or not there is a clean channel to be the operating channel for the cellular network based on the channel scan, wherein a clean channel comprises a channel that interferes with the WLAN less than a WLAN interference threshold, and selects the clean channel as the operating channel for the cellular network based on the clean channel being available or turns off the cellular network based on no clean channel being available.

The present disclosure provides a method of performing a small cell detection, a small cell base station using the same method, and a mobile electronic device using the same method. The method and the device would perform functions including a user equipment (UE) detecting a discovery signal from a small cell base station (BS) over a schedulable resource in a Macro cell frequency, the user equipment transmitting a detection report to a Macro cell BS in response to detecting the discovery signal, the UE receiving a measurement command to measure a small cell BS in the small cell frequency, and generating and transmitting the measurement report after measuring the small cell BS in the small cell frequency.

A multicast and broadcast data transmission method is provided. The multicast and broadcast data transmission method includes transmitting, at at least one synchronized macrocell base station, Multicast and Broadcast Service (MBS) data to user equipment (UE) using radio resources allocated for MBS data transmission. Here, a relay or a small cell base station in the cell of the at least one synchronized macrocell base station keeps silent for the radio resources used for the macrocell base station to transmit MBS traffic data without performing any transmitting operation. Accordingly, it is possible to increase transmission efficiency while minimizing interference in a UE, and improve the quality of a multicast broadcast service while reducing required radio resources.

Disclosed are methods for sending and receiving ACK/NACK information, a base station, and a terminal. The method for sending ACK/NACK information comprises: dividing acknowledgement (ACK)/negative acknowledgement (NACK) information of multiple terminals into X groups according to a present indication parameter, X being a positive integer greater than or equal to 1; separately performing combined coding on ACK/NACK information corresponding to each group in the foregoing X groups, so as to obtain X first blocks of bits; and mapping the foregoing X first blocks of bits to a predetermined ACK/NACK physical source and sending the foregoing X first blocks of bits. By means of the present invention, reliable transmission of HARQ-ACK information of a terminal on the NCT is implemented, the reliability of transmission of uplink data in a Low Cost terminal is improved, and problems such as a conflict of PHICH resource allocation and ICIC of a frequency domain in a small cell are solved.

The invention relates to a method for efficiently discarding data packets destined to a mobile station connected to both a master base station and a secondary base station. The master base station configures a secondary discard function in a lower layer of the secondary base station, based on the master discard function in the higher layer of the master base station. The master base station forwards the data packet from the higher layer to the lower of the secondary base station. The secondary discard function of the lower layer at the secondary base station discards the received data packet upon expiry of the secondary timer started by the lower layer upon reception of the data packet from the higher layer at the master base station.

In some embodiments, a small cell installed at a known location may observe one or more wireless signals at the known location, wherein the small cell comprises a built-in network listen receiver for observing cellular downlink signals. Subsequently, the small cell may provide, to at least one crowdsourcing server, information that identifies the location and describes one or more detected properties of the one or more observed wireless signals. In at least one arrangement, the information provided to at least one crowdsourcing server is a Positioning Reference Signal (PRS) configuration based on an observed LTE downlink signals. In at least one arrangement, the information provided to at least one crowdsourcing server is configured to be used by the at least one crowdsourcing server in providing position assistance information.

In a network in which a macro cell overlaps at least one small cell, when the carrier frequency used by the macro cell is different from the carrier frequency used by the small cell, the small cell transmits a discovery signal using the carrier frequency used by the macro cell, or the small cell transmits a discovery signal using a carrier frequency of the small cell that is different from the carrier frequency used by the macro cell.

A cell-specific dictionary is applied adaptively to adequate cells, where the cell-specific dictionary subsequently optimizes the handling of frequency-partitioned multi-dimensional data. This includes improved data partitioning with super cells or adjusting resulting cells by sub-dividing very large cells and merging multiple small cells, both of which avoid the highly skewed data distribution in cells and improve the query processing. In addition, more efficient encoding is taught within a cell in case the distinct values that actually appear in that cell are much smaller than the size of the column dictionary.
