Abstract: Described are methods, systems and devices for eliminating redundant retransmissions in radio link layer (RLC) acknowledged mode (AM) data transmissions and receptions. In some embodiments, when an RLC service data unit (SDU) has not been completely received, the value of a state variable may be selectively set based on whether or not a contiguous set of byte segments of the RLC SDU have been received. This prevents the retransmission of byte segments that are either currently being transmitted or have not yet been transmitted. In other embodiments, the selective setting of the state variable may be triggered by the expiration of a reassembly timer. The described implementations may improve the data transmission of RLC SDUs in high data rate scenarios, which may be ubiquitous in 5G implementations.

Abstract: An artificial intelligence-based cross-language speech transcription method and apparatus, a device and a readable medium. The method includes pre-processing to-be-transcribed speech data to obtain multiple acoustic features, the to-be-transcribed speech data being represented in a first language; predicting a corresponding translation text after transcription of the speech data according to the multiple acoustic features and a pre-trained cross-language transcription model; wherein the translation text is represented in a second language which is different from the first language. According to the technical solution, it is unnecessary, upon cross-language speech transcription, to perform speech recognition first and then perform machine translation, but to directly perform cross-language transcription according to the pre-trained cross-language transcription model.
