Abstract: A method for Co-Reception (Co-Rx) operation of multiple transceiver radios sharing the same antenna and Low Noise Amplifier (LNA) is provided. A first receiver radio of a wireless communication device determines the first gain mode of an LNA based on the first signal indicator. A second receiver radio of the wireless communication device determines the second gain mode of the LNA based on the second signal indicator. The LNA is shared by the first receiver radio and the second receiver radio and is coupled to an antenna. A Packet Traffic Arbitration (PTA) circuitry of the wireless communication device configures the LNA to operate in the first gain mode or the second gain mode based on the priority levels of the first receiver radio and the second receiver radio.

Abstract: A transmitter including two radio transceivers and a controller is provided. The first radio transceiver supports a first number of Spatial Streams (SS) for a first Transmission (Tx) opportunity of wireless transmission to a receiver. The second radio transceiver supports a second number of SS for a second Tx opportunity of wireless transmission to the receiver. The first Tx opportunity starts earlier than the second Tx opportunity. The controller determines whether the power consumption of SS utilization in the first and second Tx opportunities exceeds a threshold, and if so, performs one of the following: deferring the second Tx opportunity until the first Tx opportunity ends; and aborting the first Tx opportunity when the second Tx opportunity starts.

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.
