Wireless communication apparatus for performing beamforming under frequency hopping and associated wireless communication method

A wireless communication apparatus comprising:

• a channel estimation circuit, arranged to estimate a channel between the wireless communication apparatus and another wireless communication apparatus during at least one first time slot;
• a beamforming control circuit, arranged to determine beamforming coefficients according to the estimated channel;
• and
• a transmit (TX) circuit, arranged to apply the beamforming coefficients to transmission of an output data during at least one second time slot later than said at least one first time slot, wherein during said at least one second time slot, the output data is transmitted to said another wireless communication apparatus via multiple antennae,
• wherein the wireless communication apparatus performs communications according to a normal frequency hopping sequence in compliance with a communication specification,
• wherein said another wireless communication apparatus has only a single antenna,
• wherein the wireless communication apparatus is arranged to act as a slave device by sending a master-slave role switch request to said another wireless communication apparatus, and
• wherein the wireless communication apparatus is arranged to perform implicit beamforming to transmit the output data to the another wireless communication apparatus while the wireless communication apparatus acts as the slave device.
