摘要： The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as a long term evolution (LTE). An operating method of a transmitting apparatus in a wireless communication system is provided. The operating method includes detecting an achievable rate region for a receiving apparatus, and determining a modulation and coding scheme (MCS) level and a sliding window superposition coding (SWSC) multi-input multi-output (MIMO) scheme corresponding to the achievable rate region.

摘要： The disclosed techniques allow for transmitting a signal stream from a sender to a receiver in an environment including multiple senders and receivers. The technique for the sender decomposes a data stream from the sender into multiple substreams, encodes a substream by a codeword, further superimposes multiple codewords to form a signal stream in an asynchronous manner, and transmits the signal stream to the receiver. A codeword can span over multiple blocks. The receiver receives a first codeword stream from a first sender, receives a second codeword stream from a second sender, the two codeword streams may be received at the same time as one signal, and decodes the first codeword stream and second codeword stream over a sliding window of multiple blocks.

摘要： Systems and methods are disclosed for combining successive cancellation decoding of polar coding with channel estimation, using a non-elementary mixture of information and redundancy bits for both channel estimation and error correction. For example, select bits of the polar encoder output may be used for an implicit parity check. Reliably-decoded bits may be iteratively incorporated into the set of pilots. The result is a semi-blind approach for channel estimation, which may have applicability to common wireless communication systems, particularly a cellular control channel, or transmissions of short messages on a cellular data channel.
