  • Publication number: 20180070317
    Abstract: Methods and apparatuses pertaining to uplink power consumption reduction for a Narrow Band-Internet of Things (NB-IoT) apparatus. The NB-IoT apparatus may transmit uplink data to a network apparatus via an uplink channel. The network apparatus may decode the uplink data. The network apparatus may further transmit an acknowledgement (ACK) indicator to the NB-IoT apparatus before receiving all the uplink data if the uplink data is decoded successfully. The NB-IoT apparatus may monitor whether an ACK indicator is received from the network apparatus during a transmission gap of the uplink channel. The NB-IoT apparatus may further terminate uplink data transmission if the ACK indicator is received.

  • Patent number: 8854897
    Abstract: A static random access memory apparatus and a bit-line voltage controller includes a controller, a pull-up circuit, a pull-down circuit and a voltage keeping circuit. The controller receives a bank selecting signal and a clock signal, and decides a pull-up time period, a pull-down time period and a voltage keeping time period according to the bank selecting signal and the clock signal. The pull-up circuit pulls up a bit-line power according to a first reference voltage within the pull-up time period. The pull-down circuit pulls down the bit-line power according to a second reference voltage within the pull-down time period. The voltage keeping circuit keeps the bit-line power to equal to an output voltage during the voltage keeping time period. The voltage keeping time period is after the pull-up time period and the pull-down time period.

  • Publication number: 20140092798
    Abstract: An embodiment of the invention provides a method performed by a mobile communication device in a discontinuous reception (DRX) mode. First, the device dumps contemporarily received data and performs multipath search while a beginning part of a relevant sub-frame in a control channel is being transmitted. Next, the device dumps contemporarily received data and decodes dumped data with an accelerated rake while a middle part of the relevant sub-frame is being transmitted. Then, the device decodes contemporarily received data with a normal rake while an ending part of the relevant sub-frame is being transmitted.
