Abstract: A wireless communication terminal including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception to and from an AP. The controller is coupled to the wireless transceiver, and is operable to configure the wireless communication terminal to operate as a non-AP STA, and transmit a MU PPDU with a single RU spanning a partial bandwidth of the MU PPDU to the AP via the wireless transceiver. In particular, the partial bandwidth excludes a frequency band of a primary channel.

Abstract: A portable device for receiving broadcast information is provided. A mixer down-converts a radio-frequency signal with a local oscillation clock to provide an intermediate frequency signal. A filter is arranged to filter the intermediate frequency signal. An analog-to-digital converter converts the filtered intermediate frequency signal into a digital signal according to a sampling rate. The broadcast information is obtained according to the digital signal. The local oscillation clock has a first frequency in a normal mode and a second frequency in a power-saving mode, and the second frequency is lower than the first frequency.
