Abstract: Systems and methods for determining a timing of a random access channel (RACH) occasion (RO) used to transmit a contention free random access (CFRA) preamble triggered by the receipt of an physical downlink control channel (PDCCH) order in a PDCCH are disclosed herein. A user equipment (UE) receives the PDCCH order and determines a timing offset value between the RO and a signal (e.g., a synchronization signal block (SSB), the PDCCH, a reference signal, etc.) to be used as a timing source. The UE also determines the arrival time of the signal to be used at the timing source. The UE then determines a time of the RO (during which the CFRA preamble will be transmitted) according to the arrival time and the timing offset value. Timing advance (TA) value(s) may also be accounted for as part of such a determination.

Abstract: Techniques discussed herein can facilitate inter-cell interference mitigation. One example aspect is a user equipment (UE), configured to receive a network assistance indication associated with an interfering signal, where the interfering signal interferes with a physical downlink shared channel (PDSCH) transmission. A time resource allocation of the interfering signal is different than a time resource allocation of the PDSCH transmission. The UE is further configured to determine an interference and noise covariance estimation mechanism based on the network assistance indication then perform interference and noise covariance estimation based on the noise covariance estimation mechanism. The UE is further configured to perform mitigation of the interfering signal using a mitigation mechanism based on the interference and noise covariance estimation.

Abstract: A user equipment (UE) may support concurrent synchronization signal block (SSB) inter-frequency measurement without a measurement gap (MG). The UE may also, or alternatively, support concurrent SSB inter-frequency measurement in intra-band scenarios (e.g., where a target inter-frequency cell and serving cell are on the same band) and/or inter-band scenarios (e.g., where a target inter-frequency cell and serving cell are on the same band). The UE may report concurrent SSB based inter-frequency measurement as a NEEDFORGAP information element (IE), which may include one or more of a variety of parameters regarding UE measurement capabilities. Scheduling restrictions (e.g., restrictions to downlink and uplink communications) are also enabled based on UE measurement capabilities, including scheduling restriction for frequency range 1 (FR1), frequency range 2 (FR2), and cross frequency range scenarios.

Abstract: Many unsupervised domain adaptation (UDA) methods have been proposed to bridge the domain gap by utilizing domain invariant information. Most approaches have chosen depth as such information and achieved remarkable successes. Despite their effectiveness, using depth as domain invariant information in UDA tasks may lead to multiple issues, such as excessively high extraction costs and difficulties in achieving a reliable prediction quality. As a result, we introduce Edge Learning based Domain Adaptation (ELDA), a framework which incorporates edge information into its training process to serve as a type of domain invariant information. Our experiments quantitatively and qualitatively demonstrate that the incorporation of edge information is indeed beneficial and effective, and enables ELDA to outperform the contemporary state-of-the-art methods on two commonly adopted benchmarks for semantic segmentation based UDA tasks.

Abstract: A visual loop-mediated isothermal amplification (LAMP) method for a rapid test of tobacco includes: extracting a genomic DNA of the tobacco, designing primers, establishing a LAMP reaction system, and optimizing the LAMP reaction system. The present disclosure designs the LAMP primers according to a conserved region of a screened tobacco-specific Ntsp151 genomic sequence, and establishes the LAMP method based on color determination. The present disclosure can rapidly identify flue-cured tobacco leaves, finished cigarettes, and tea cigarettes, and achieves a detection limit of 200 copies per reaction. The test results of the LAMP method for non-tobacco samples are negative, indicating that the LAMP method has high specificity. Compared with the quantitative polymerase chain reaction (qPCR) method, the LAMP method has a coincidence rate of 96.7%, but the LAMP method only needs about 1 h to obtain the results.
