摘要： Methods and apparatus are provided for identifying a connection between a reach extender channel termination (RE-CT) and an optical network unit (ONU). A method performed by an optical line terminal (OLT) for identifying a connection between a RE-CT and an ONU includes transmitting, by the OLT, a dynamic bandwidth allocation (DBA) grant to the ONU via a multi-channel termination reach extender (MCRE), retrieving, by the OLT from the MCRE, recorded optical signal power measurements associated with an upstream transmission by the ONU, and identifying, by the OLT, the RE-CT of the MCRE that is connected to the ONU by correlating the recorded optical signal power measurements associated with the upstream transmission by the ONU with the DBA grant.

摘要： A method for communicating data between a transmitter and receiver is described. The method comprises receiving a data payload comprising a plurality of codewords, the codewords encoding data from non-overlapping data portions of information bits corresponding to the data payload, decoding the plurality of codewords, generating an acknowledgement message comprising an indication of a subset of codewords that are decoded correctly, communicating the acknowledgement message to obtain a retransmission of codewords corresponding to codewords that were decoded incorrectly and receiving, in response to the acknowledgement message, one or more codewords encoding data from at least one portion of the non-overlapping data portions. The acknowledgement message is generated on the basis of an identification of the codewords in the subset and a corresponding subset of correctly decoded non- overlapping data portions having information bits encoded in codewords in the subset.

摘要： The present invention relates to Hybrid Automatic Repeat Request, HARQ, in wireless communication technologies, particularly HARQ for IEEE 802.11, i.e. HARQ for Wi-Fi. To this end, the invention proposes a transmitting device and a receiving device, respectively, both configured to support such HARQ in Wi-Fi. The transmitting device is configured to: encapsulate a data unit in a container unit, encode the container unit into a codeword set of one or more codewords. Accordingly, the receiving device is configured to receive from the transmitting device at least one codeword set of one or more codewords, decode the codewords of the codeword set to obtain a container unit, and decapsulate the container unit to obtain a data unit. Thereby, a bit-size of the container unit is equal to the bit-size of the codeword set in the transmitting device and receiving device.
