Abstract: The present disclosure relates to managing transmissions across multiple time-domain resources, including receiving, by a User Equipment (UE) from a network, one or more of at least one frequency-domain starting position for a transmission, at least one frequency resource set for the transmission, or at least one frequency hopping configuration set for the transmission. The UE determines a plurality of time-domain resources for repeating the transmission or for multiple transmissions scheduled by a same scheduling command. The UE determines at least one of a frequency-domain starting position, a frequency-domain resource set, or a frequency hopping configuration set for the transmission in each of the plurality of time-domain resources.

Abstract: The present disclosure is directed to UL cell and SCell activation, including sending, by a base station to a wireless communication device, a Secondary Cell (SCell) activation command triggering at least SCell activation and measurement signal for at least one SCell, and receiving, by the base station from the wireless communication device, the measurement signal in response to the SCell activation command, wherein the wireless communication device activates the at least one SCell in response to the SCell activation command.

Abstract: An apparatus and method for keeping output loudness and quality of sound in different equalizer modes. The apparatus includes a gain setting unit configured to set a protection limit of an output voltage of an input audio signal; an equalizer (EQ) mode filter configured to filter the input audio signal so as to achieve the different equalizer modes; an amplitude real-time processing module configured to receive the audio signal output from the EQ mode filter or an audio signal feedback, and process the received audio signal such that the output voltage of the processed audio signal is lower than the protection limit; and a digital-to-analog converter configured to perform a digital-to-analog conversion on the processed audio signal, and output an analog audio signal.

Abstract: Disclosed is a method for preparing 1-octene in the presence of a catalyst system for ethylene oligomerization, which includes: premixing a part of ethylene gas as raw material with a solvent, mixing with the components a+b, c and d of the catalyst system, and then sending in a reactor; directly sending the rest of ethylene gas in the reactor; discharging the resultant liquid from the upper part of the reactor into an overflow channel; adding a catalysis stopping agent to the overflow channel; and then separating the resultant liquid. The advantages of the method are high selectivity of 1-octene and high catalytic activity.
