    摘要： Systems and methods of expanding indication capabilities of existent PPDU preamble fields. The "GI+LTF Size" field is redefined to indicate a new combination of GI duration and HE-LTF size. The redefinition is indicated when the values of the two other existent fields, in combination, indicate an invalid scenario because the two values should have been mutually exclusive. Particularly, the DCM field and the STBC field are both set to the "enabled" mode as an indication for redefine the "GI+LTF Size" field. Upon receiving such a PPDU, a receiver is configured to resolve the PPDU as neither DCM nor STBC is enabled. Rather, the receiver interprets the particular combination of DCM and STBC values as an indication that the "GI+LTF Size" field is redefined to indicate the new combination of GI duration and HE-LTF size.

    摘要： A data communication method using forward error correction (FEC) includes: receiving at least one of symbols that constitute one encoding block unit; extracting information related to parameters that adjust an FEC encoding rate from the at least one symbol; determining whether an error may be corrected based on the extracted information related to the parameters and a number of symbols with errors from among the symbols that constitute the encoding block unit; and transmitting feedback information related to the symbols prior to the symbols that constitute the encoding block unit being completely received based on the determination of whether an error may be corrected.

    摘要： Disclosed is a method and an apparatus providing antenna port sharing and a demodulation reference signals (DMRS) based precoding scheme for a distributed enhanced physical downlink control channel (E-PDCCH) using, for example, spatial frequency block codes (SFBC)/frequency selective transmit diversity (FSTD) transmit diversity. The method exhibits the same performance as SFBC/FSTD transmit diversity using un-precoded DMRS while not prohibiting another UEs' localized E-PDCCH to be potentially multiplexed in a same physical resource block (PRB) pair. The SFBC/FSTD transmission is facilitated by mapping a subset of layers to DMRS ports used by other UEs for localized and beamformed transmission, while the precoders for the remaining layers arc selected to be orthogonal to the other UEs precoders thereby providing good performance wide minimizing DMRS port usage. Specifically, no additional DMRS ports are needed for spatial diversity transmission.

    摘要： An iterative receiver is proposed for receiving in a cell a signal and for providing information carried on the signal by execution of at least one processing iteration. The receiver includes an estimate assembly for receiving the signal and providing, at each one of the processing iterations, a respective information estimate; a regeneration assembly for receiving, at each processing iteration, the information estimate provided by the estimate assembly at that iteration, and for providing a regenerated signal therefrom based on the information estimate and on attenuation of radio channels over which the signal has been transmitted; an interference estimate unit for providing, at each iteration, an interference estimate based on the signal and the regenerated signal, the estimate assembly providing, starting from a second processing iteration of the processing iterations, the information estimate based on the interference estimate; and an extraction unit for extracting the information from the information estimate.

    摘要： Information symbols are transmitted simultaneously on independent streams using the same spreading code (344) but from different transmit antennas (332a, 334a, 332b, 334b) at the transmitter. These simultaneous data stream could be intended for the same user (and thereby the data rate for any particular user can be increased) or for different users (thereby increasing the system capacity). Each stream of data can belong to a different signal constellation and use a different channel code (324a, 324b). At the receiver, a number of receive antennas equal to at least the number of multiple data streams is used to separate the different data streams. We consider two different cases. The first one when no transmit diversity is used (this case can also include the case when transmit diversity with simple antenna weighting is used) and the second when transmit diversity with space-time block coding is used.

    摘要： A client device includes one or more processors configured to receive, from a server device, forward-error corrected data via a plurality of parallel network paths, determine losses of the data over each of the network paths, and send data representing the losses of the data over each of the network paths to the server device. Additionally or alternatively, a client device includes one or more processors configured to receive a first set of encoding units for a first block, wherein the first set of encoding units includes fewer than a minimum number of encoding units needed to recover the first block, after receiving the first set of encoding units, receive a second set of encoding units for a second block, and after receiving the second set of encoding units, receive a third set of encoding units including one or more encoding units for the first block.
