Abstract: The present invention relates to an apparatus and a corresponding method for mapping error correction code encoded time-domain data of at least two mapping input data streams (S1, S2, . . . , Sn) onto a time-domain mapping output data stream (Q) having a frame structure, comprising a data input (102) for receiving said at least two mapping input data streams (S1, S2, . . . , Sn) each being segmented into data blocks (D1, D2, . . . , DN) carrying error correction code encoded data, a data mapper (104) for mapping the data blocks (D1, D2, . . . , DN) of said at least two mapping input data streams (S1, S2, . . . , Sn) onto frames of said mapping output data stream (Q), each frame comprising a number of frame intervals (F1, F2, . . . , FM), wherein the data mapper (104) is adapted for mapping the data blocks (D1, D2, . . . , DN) onto said frame intervals such that each frame interval (F1, F2, . . . , FM) carries sequentially arranged data blocks (D1, D2, . . . , DN) from various mapping input data streams (S1, S2, . . . , Sn) and that within a frame the mapping of data blocks (D1, D2, . . . , DN) from the various mapping input data streams (S1, S2, . . . , Sn) onto frame intervals (F1, F2, . . . , FM) is different from frame interval to frame interval, and a data output (110) for outputting said mapping output data stream (Q).

Abstract: A system, apparatus and method is disclosed for multiband wireless communication. Frequency bands and/or transmission formats are identified as available within a range for wireless communication. The system evaluates signal quality metrics for each frequency band and selects a communication method based on the evaluation. Multiple frequency bands and communication methods can be utilized by the system such that a combination of licensed, unlicensed, semilicensed, and overlapped frequency bands can be simultaneously used for communication. The system monitors communications and can report link performance for adaptive control of the selected communication methods.

Abstract: A transmitter may initiate multiple-input multiple-output (MIMO) communications with a receiver in which a number of codewords used in MIMO transmissions may be selected to provide enhanced communications for a particular service that is associated with the MIMO transmission. In cases where a lower-latency service is identified, a MIMO transmission may be configured with one codeword transmitted over multiple spatial layers, which may provide lower processing latency at a receiver relative to processing of multiple codewords. In cases where a mobile broadband service is identified, a MIMO transmission configured with two (or more) codewords may be transmitted over multiple spatial layers, which may provide increased data throughput relative to a single codeword MIMO transmission. A codeblock size for a transmission also may be selected based at least in part on a service associated with the transmission.

Abstract: A radio node (52) in a wireless communication system (10) employs multiple different candidate formats (22) that define different possible positions of decoding checks (24) within a transport block of a specific size. The radio node (52) determines, from these different candidate formats (22), a format that defines a position of decoding checks (24) within a transport block (16) to be encoded or decoded. The radio node (52) then encodes or decodes at least a portion of the transport block (16) based on the determined format.

Abstract: The present invention relates to a method of improving the performance in bandwidth constrained communication systems while reducing the complexity of the equalizer used for information retrieval, as well as to improving the capacity of communication systems. The said properties are achieved by appropriate information encoding, prior to signal shaping before transmission, whereas the equalizer complexity is reduced by applying the intersymbol interference shortening filter prior to the information retrieving equalization. A proper combination of the recounted elements is capable of providing a qualitatively improved and previously unsuspected performance, as compared to its constituent elements.

Abstract: Disclosed is a system for mitigating co-channel interference (CCI) caused due to narrow multiband signal in white space (WS) modems. The system includes a base-station that includes a base-station transmitter and a base-station receiver. The base-station receiver receives an orthogonal frequency division multiplexing signal (OFDM) from one or more customer premises equipment (CPE) transmitters. An interference detection module detects a presence of co-channel interference in carriers of the OFDM signal and determines co-channel interference affected carriers. A dynamic notch filter module receives the central interference carriers from interference detection module and mitigates the co-channel interference of co-channel interference affected carriers without affecting frame detection capability of the system. The base-station transmitter includes an interference aware frequency interleaver that spreads co-channel interference affected carriers based on interference specific interleaving parameters and frequency de-interleaving is performed corresponding to frequency interleaving in the base-station receiver.
