    Abstract: The present invention provides a wireless communication circuitry including a processor, a communication path and a channel detection path. The communication path is configured to wirelessly communicate with an electronic device by using a first channel. The channel detection path is configured to detect at least one channel different from the first channel to generate a detection result while the communication path is wirelessly communicating with the electronic device by using the first channel. The processor determines a second channel based on the detection result, and the processor controls the communication path to switch to the second channel from the first channel to communicate with the electronic device.

    Abstract: A calibration apparatus for calibrating a transceiver includes a loop back circuit, an estimation circuit, and a calibration circuit. The loop back circuit is coupled between a mixer output port of a transmitter (Tx) of the transceiver and a mixer input port of a receiver (Rx) of the transceiver, and applies a sequence of different loop gains. The estimation circuit receives a loop back receiving signal that is output from the Rx under the sequence of different loop gains, and generates at least one estimated value of impairment of the transceiver by performing channel estimation according to at least the loop back receiving signal. The calibration circuit performs calibration upon the transceiver according to the at least one estimated value.

    Abstract: Techniques pertaining to methods to reduce channel accessing delay for Bluetooth system using listen before talk (LBT) in wireless communications are described. An apparatus performs LBT on a channel and, based on a result of the LBT, the apparatus transmits on the channel responsive to the channel being deemed unoccupied. In performing the LBT, the apparatus performs the LBT with at least one of: (a) dynamic transmit (Tx) power control (TPC) with an adaptive energy detection (ED) threshold; (b) an extended clear channel assessment (CCA) time; and (c) the extended CCA time with a multi-block format of transmission.

    Abstract: A communication apparatus is provided. The communication apparatus includes an RF module for receiving an RF signal, and a down converter, coupled to the RF module, for down converting the RF signal in response to a channel select signal to generate a converted signal. The channel select signal controls the down converter to sweep a plurality of scan trains during a scan frame, and each of the scan trains comprises a plurality of channels, wherein a total channel number of the plurality of scan trains is N, where 32≦N≦78. The communication apparatus also includes a detector, coupled to the down converter, for determining whether the RF signal comprises an ID packet according to the converted signal corresponding to the channels of the plurality of scan trains.
