Abstract: A wireless communication apparatus includes a channel estimation circuit, a beamforming control circuit, and a transmit (TX) circuit. The channel estimation circuit estimates a channel between the wireless communication apparatus and another wireless communication apparatus during at least one first time slot. The beamforming control circuit determines beamforming coefficients according to the estimated channel. The TX circuit applies the beamforming coefficients to transmission of an output data during at least one second time slot later than the at least one first time slot. During the at least one second time slot, the output data is transmitted to another wireless communication apparatus via multiple antennae. The wireless communication apparatus performs communications according to a normal frequency hopping sequence in compliance with a communication specification.

Abstract: A communications apparatus includes a plurality of communications circuits and a coexistence management circuit. Each communications circuit is configured to provide wireless communications services in compliance with a protocol. The coexistence management circuit is configured to manage radio activities of the communications circuits. In response to a detection result of at least two radio activities to occur in a subsequent packet time, the coexistence management circuit is configured to determine whether an interference signal related to said at least two radio activities falls in a predetermined frequency band, and when the interference signal falls in the predetermined frequency band, the coexistence management circuit is configured to adjust a transmission power or an execution time of one of said at least two radio activities.

Abstract: A wireless communication includes a control circuit and a receiver (RX) circuit. The control circuit obtains indicator information from another wireless communication system, identifies a transmitter (TX) and receiver (RX) packet delivery scenario as one of a packet overlapping scenario and a packet non-overlapping scenario according to the indicator information, and generates RX gain control information in response to the TX and RX packet delivery scenario. The RX circuit refers to the RX gain control information to set an RX gain used for receiving data.
