摘要： Method performed by a transmitting device (101) for transmitting a block to a receiving device (102). The transmitting device (101) and the receiving device (102) operate in a wireless communications network (100). The transmitting device (101) transmits a block to the receiving device (102). The block comprises four bursts. The four bursts further comprise Uplink State Flag, USF, Stealing Flag, SF, and data and header fields. The USF and the SF fields are interleaved and mapped over the four bursts. The data and header fields are interleaved over one burst but repeated over the four bursts. The data and header fields are overlapping with and overridden by bits from the USF field in different positions in each burst. In a method performed by the receiving device (102), the receiving device (102) receives the transmitted block. In a method performed by a controlling node (140), the controlling node (140) selects a block format for transmission by the transmitting device.

摘要： A method processes a data packet in a first sequence of disjoint original segments of the same length. The method includes modifying a first of the original segments of the first sequence by modifying one or more symbols therein. A start of the data packet is located in the first of the original segments and is positioned after a first digital data symbol therein. The method also includes modifying a last of the original segments of the first sequence by modifying one or more digital data symbols therein. An end of the data packet is located in the last of the original segments and is located before the last digital data symbol therein. The method also includes determining a remainder sequence by effectively performing a polynomial division on a second sequence of disjoint segments that are derived from the first sequence. Each segment of the second sequence corresponds to and is derived from one of the original segments of the first sequence. The segments of the second sequence have the length of the original segments of the first sequence. A first of the derived segments of the second sequence is the modified first of the original segments. A last of the derived segments of the second sequence is derived from the modified last of the original segments.

摘要： A physical layer (PL) frame generation method is provided. A PL payload is generated by encoding and modulating source data based on a first modcod of a first set. A synchronization header (a unique word (UW) of a UW set) is appended to the PL payload. The UWs of the set respectively correspond to different modcods of the first set, and the UW corresponds to the first modcod. A PL header is appended to the synchronization header and PL payload to form the PL frame. The PL header comprises a second UW and physical layer signaling (PLS). The PLS comprises encoded data fields reflecting a length of the PL frame, where the data fields are encoded based on a second modcod scheme of a second set. The first modcod set is designed for an SNR operating range relatively lower than the SNR operating range of the second modcod set.
