Abstract: A technology to optimize power consumption by reducing the transmission number of SR/PUSCH is provided. The controlling method for the user equipment includes the following steps: determining whether the user equipment receives a scheduling request (SR) configuration from a network; reducing SR transmission number by selecting a plurality of SR occasions; and transmitting a SR signal according to selected SR occasions.

Abstract: An UL HARQ operation enhancement for power enhancement/saving is provided. A controlling method for the user equipment includes the following steps. A waiting section for receiving a retransmission (RETX) grant signal or a Negative Acknowledgement (NACK) signal is set. Whether the user equipment receives a Acknowledge (ACK) signal is determined. After the ACK signal is received, time or count is counted. Whether the waiting section is reached is determined. After the waiting section is reached, monitoring Physical Downlink Control Channel (PDCCH) and/or Physical Hybrid ARQ Indicator Channel (PHICH) is stopped.

Abstract: A 3D positioning system and method, adapted for object tracking and positioning of virtual reality is provided. The method comprises: tracking a characteristic of at least a light-emitting component at a controller; calculating relative displacement information between each of the controller and a headset display device according to the characteristic; detecting first displacement information of the headset display device and second displacement information of each of the controller; transmitting the relative displacement information, the first displacement information, and the second displacement information to the host; and adjusting a corresponding virtual image of the virtual reality according to the relative displacement information, the first displacement information, and the second displacement information and transmitting the adjusted virtual image to the headset display device to display via the host.
