    Abstract: A base station 100 provides communications services via one of a plurality of interfaces 111-113, 121-123, each supporting a different communications protocol, in consideration of user terminal information (e.g. protocols supportable), interface information (e.g. capacity and interference) and quality information. The base station 100 comprises an interface unit 110, 120 that includes the plurality of interfaces 111-113, 121-123 supporting the different communications protocols, a control unit 130 that selects one of the plurality of interfaces and controls the connection of user terminals and the selected interface 132, and a core network connection unit 140 that connects the interface selected by the control unit 130 to a wired network. Both mobile communications interfaces 111-113, supporting different mobile communications protocols (e.g. wideband code division multiple access (WCDMA), long term evolution (LTE), worldwide interoperability for microwave access (WiMAX), and wireless broadband (WiBro)), and wireless communications interfaces 121-123, supporting different wireless communications protocols (e.g. wireless local area network (WLAN), and Bluetooth), may be provided.

    Abstract: In a multiple-input multiple-output (MIMO) receiver employing channel estimation 10 and the `adaptive QR-decomposition with M' (AQRDM) algorithm 20, complexity is reduced when the number of transmitting antennas is large by grouping constellation sets 40 and dividing the tree search into partial detection phases (PDPs) 50, thus cutting the number of remaining branches at each detection point. Each of the G subsets Ai of constellation set E2 have the same cardinality (number of set elements) and can be grouped continuously (see fig. for 16QAM with G1=4) or dispersively (fig. 2B for 16QAM with G2=4). For each symbol, the minimum accumulated distance per PDP is calculated, and nodes for which this exceeds threshold (fig 3B) are removed in order to simplify the decision process.

    Abstract: A packet combining device for a communication system using hybrid automatic repeat request (HARQ) includes: a HARQ buffer; a combiner configured to combine data which is previously received and stored in the HARQ buffer with newly-received data; and a channel decoder configured to attempt channel decoding by using the combined received data provided from the combiner and provide one or more of log likelihood ratios (LLRs) computed for a systematic bit and a parity bit of the combined received data to the combiner such that the one or more LLRs are combined with the data used for channel decoding.

    Abstract: In a chase combining (CC) hybrid automatic repeat request (HARQ) system in which previously-transmitted packet information 304 is combined with retransmitted packets, a log-likelihood ration (LLR) is computed for both a parity bit (607) and a systematic bit (606) and supplied 308 to a combiner 303 to be combined with data used for channel decoding 307. Decoding may be iterative (eg. LDPC or turbo) and use BCH, Reed-Solomon, SOVA or MAP algorithms.

    Abstract: PURPOSE: A wireless frequency resource scheduler of a mobile system is provided to reduce the complexity of a resource scheduler by adaptively changing a scheduling resolution based on CQI(Channel Quality Indicator) features of all mobile stations. CONSTITUTION: A frequency resolution determination apparatus(110) receives the CQI information of all mobile stations for each frequency band of a mobile communication system. The frequency resolution determination apparatus divides the all frequency bands as resolution sizes. The frequency resolution determination apparatus compares the CQI information and reference performance values for each resolution for the all mobile stations. The frequency resolution determination apparatus outputs the biggest resolution in available resolutions. A frequency resource assignment unit(120) applies frequency assignment by using the outputted frequency resolution.
