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.

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.
