摘要: Embodiments of the present invention relate to a data transmission method and apparatus based on unequal error protection and a device. The method includes: segmenting, according to a quantity of symbol bits in a constellation diagram, a code block corresponding to data, to obtain segmented code blocks; performing rate matching on the segmented code blocks obtained by channel encoding, to obtain output code blocks; cascading the output code blocks according to the quantity of symbol bits in the constellation diagram, to obtain cascaded code blocks; and sending the cascaded code blocks to a terminal device.

摘要: When receiving a first data frame sent by a transmitting apparatus, a receiving apparatus may return error indication information including an identifier of at least one erroneous codeword group to the transmitting apparatus if it is found that an error occurs in an initial codeword of the first data frame. The transmitting apparatus may obtain the erroneous codeword group and encode the erroneous codeword group, and retransmit a part of a sub check codeword obtained through encoding to the receiving apparatus. The receiving apparatus may obtain a third check matrix based on a first check matrix, a second check matrix, and a location of the at least one erroneous codeword group in the initial codeword, and re-decode the retransmitted partial sub check codeword and content of the first data frame together based on the third check matrix, so as to obtain a correct initial codeword.

摘要: The present invention provides a synchronization signal sending method and apparatus and a synchronization signal receiving method and apparatus. The synchronization signal sending includes: a sending module, configured to send a first-type subframe, where the first-type subframe includes a physical downlink shared channel (PDSCH) and a first synchronization channel, the first synchronization channel includes a first primary synchronization signal (PSS) and a first secondary synchronization signal (SSS); and a processing module, configured to control the sending module to switch from sending the first-type subframe to sending a second-type subframe. The sending module is further configured to send the second-type subframe under the control of the processing module, where the second-type subframe includes a physical uplink shared channel (PUSCH) and a second synchronization channel, the second synchronization channel includes a second PSS or a second SSS.
