  • Patent number: 11108431
    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.

  • Patent number: 9277565
    Abstract: Methods for preventing coexistence interference between a Bluetooth Low Energy (BLE) radio and a collocated LTE radio are provided. In a first solution, the BLE radio adds padding bytes to BLE packets such that the total packet length falls in a specific range to prevent coexistence interference. In a second solution, the BLE radio limits the total BLE packet length to a predefined length to prevent coexistence interference. In a third solution, the data rate for transmitting the BLE packets is higher than a predefined rate to prevent coexistence interference. In a fourth solution, the BLE radio dynamically adjusts the time inter-frame-spacing (T_IFS) value to prevent coexistence interference with the collocated LTE radio.
