Abstract: A system and a method for treating salt-containing glycerin wastewater are provided, wherein the system for treating the salt-containing glycerin wastewater includes a mixing tank, a filtering device, a distillation column, and a water supply device. The mixing tank is adapted to mix salt-containing glycerin wastewater with a concentrated hydrochloric acid to obtain a mixture. The filtering device communicates with the mixing tank and filters the mixture to obtain an acidic filtrate and a precipitated salt. The distillation column communicates with the filtering device and receives the acidic filtrate from the filtering device. The water supply device supplies water to the acidic filtrate. The system and method for treating the salt-containing glycerin wastewater can effectively recycle hydrochloric acid.

Abstract: A communications apparatus includes a radio transceiver and a processor. The radio transceiver receives a plurality of feedback messages from a peer device. The feedback messages are transmitted by the peer device to indicate a result of UL data transmission. The processor analyzes content of the feedback messages to determine a preferred retransmission type of the peer device and records the preferred retransmission type of the peer device in a memory device. When the radio transceiver receives a first UL grant message indicating transmission of a first UL data and the processor determines that a forthcoming first feedback message corresponding to the transmission of the first UL data is unable to be received, the processor determines whether to retransmit the first UL data according to the preferred retransmission type of the peer device.

Abstract: A method of minimizing service degradation caused by other-SIM-occupancy of a DSDS or MSMS UE under carrier aggregation is proposed. A UE performs CC selection from the multiple CCs associated with a first SIM to suffer from other-SIM-occupancy to minimize potential service degradation. In a first option, the UE selects one or more CCs that are relatively harmless from other-SIM-occupancy to share HW resource with CCs associated with other SIMs. In a second option, the UE schedules other-SIM-occupancy on more than one CCs of the first SIM to reduce the frequency and duration of the other-SIM-occupancy affected to each chosen CC of the first SIM.

Abstract: A mobile communication device including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception to and from a service network via a plurality of component carriers. The controller determines a plurality of service levels, each corresponding to a respective one of the component carriers, and allocates uplink resource assignments for uplink data transmissions according to the service levels and traffic type of the uplink data.
