Abstract: Various aspects described herein relate to techniques for rate matching and interleaving in wireless communications (e.g., 5G NR). In an example, a method described herein includes encoding one or more information bits to generate a first codeblock, rate matching the first codeblock to generate a second codeblock, segmenting, using bit distribution, the second codeblock into one or more sub-blocks each having a plurality of bits. The method further includes interleaving the plurality of bits on each of the one or more sub-blocks, concatenating, using bit collection, the one or more sub-blocks to generate a third codeblock in response to the interleaving, and transmitting a signal using the third codeblock.

Abstract: Methods, systems, and devices are described for wired communication. In one aspect, a method relates to detecting cable impairments with reflectometry. The method includes transmitting a test signal and receiving one or more reflected signals in response to the test signal. The method also includes applying a first asymmetric windowing function to the one or more reflected signals to generate frequency domain data. Additionally, the method includes transforming the frequency domain data from a frequency-domain representation to a time-domain representation to generate a time domain reflectometry (TDR) signal. The method can detect and locate a bridge tap, line cut, and/or termination condition on the transmission line.

Abstract: Methods, systems, and devices are described for wired communication. In one aspect, a method relates to a scheme to filter and enhance a time domain reflectometry (TDR) plot with pre-processing such that the plot shows impairments clearly and reduces spurious peaks. The method includes receiving one or more reflected signals in response to a transmitted test signal. The method also includes determining a time domain reflectometry (TDR) signal based at least in part on frequency response data associated with the received one or more reflected signals. Additionally, the method includes applying a de-emphasis windowing function to the TDR signal.

Abstract: According to certain aspects, the present invention relates to methods and apparatuses to identify and locate a line-cuts in a loop that may or may not also contain bridgetaps. In embodiments, different bands of SELT signal data are analyzed separately using a TDR method, to effectively detect any potential bridgetaps. In these and other embodiments, by combining information from the separate bands, bridgetap locations and lengths are determined. Methodology is also established to distinguish legitimate line cut or bridgetap signal data from spurious data. According to certain aspects, embodiments of the invention also incorporate baselining, which includes tests to make sure that there are no inconsistencies or imperfections that can corrupt the SELT data.

Abstract: Methods and apparatuses are disclosed for detecting improper connection near the end of an xDSL loop based on separately analyzing the location and levels of time domain signals associated with different transmission bands in an xDSL band plan. In one embodiment, a method is disclosed to separately convert the received test signal data to different sets of time domain data corresponding to different sets of the separate frequency bands, and then to separately analyze the different sets of time domain data to identify an improper connection near the modem.

Abstract: According to certain aspects, embodiments of the invention relate to methods and apparatuses to detect loss of connectivity due to improper connection near the CPE modem (i.e. small loop condition) based on the analysis of SELT. In embodiments, this condition is detected based on separately analyzing the location and levels of time domain signals associated with different transmission bands in an xDSL bandplan.
