Abstract: Provided is a pattern division multiple access (PDMA) communication system based on optimal frequency-hopping patterns, which includes a transmitter and a receiver. The transmitter modulates an input baseband signal into a modulated signal, and then converts the modulated signal into a signal that hops in frequency according to the optimal frequency-hopping pattern. The receiver reverts the received frequency-hopping signal to an output modulated signal using an optimal frequency-hopping pattern same as that of the transmitter, and then demodulates the modulated signal into a baseband signal. The optimal frequency-hopping patterns are obtained by applying two-dimensional cyclic shift to a Golomb Costas array constructed based on an extension field, and thus are frequency-hopping patterns with ideal autocorrelation and cross-correlation properties.

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of link adaptation with unlicensed channel access of CG PUSCH. The method comprises receiving, at a first device and from a second device, a configuration of at least two candidate resources for a transmission from the first device to the second device, selecting, from the at least two candidate resources, a target resource for the transmission based on an availability of a channel occupancy time, COT, initiated by the second device for the transmission, and performing the transmission based on the selected target resource. This solution facilitates low latency CG PUSCH operation, where channel access probability can be improved by Tx power adjustment when needed, by allowing the UE to select the most appropriate CG-PUSCH resource. In this way, the use of CG PUSCH resources may be more effective and the UE operation and the gNB detection can also be simplified.

Abstract: The present disclosure discloses a preparation method of ginseng composition with high ginsenoside bioavailability. The composition is composed of ginseng powder of 250 meshes or more and ?-cyclodextrin, and the mass ratio of the ginseng powder to the ?-cyclodextrin is 1:0.05. Results show that when ?-cyclodextrin is used as a solid dispersant and added to the 1000-mesh ginseng powder at a mass ratio of 5%, the total dissolution amount is maximum; and furthermore, animal experiments (SD rats) show that the area under the plasma drug concentration-time curve (AUC0-48 h) after 48 h of ginseng powder ingestion is maximum, indicating that in-vivo bioavailability of the ginseng powder is the highest. The method of this application can effectively inhibit the aggregation of the ultra-finely pulverized 1000-mesh ginseng powder by adding the ?-cyclodextrin, thus significantly improving the total dissolution amount of ginsenoside.
