    • Embodiments provide a method and apparatus for performing time division duplex communication, such as may be performed over a wireless communications network. In the embodiments a first circuit pathway is used to transmit a first radio frequency signal in a transmission mode and a second circuit pathway is used to receive a second radio frequency signal in a reception mode. In the reception mode, the first radio frequency signal is switched to an alternate circuit pathway. This may be performed by a radio frequency integrated circuit or by other control circuitry. Switching to an alternate circuit pathway reduces leakage of the first radio frequency signal into the second radio frequency signal.
    • 实施例提供了一种用于执行时分双工通信的方法和装置,诸如可以通过无线通信网络来执行。 在实施例中,第一电路路径用于以传输模式传输第一射频信号,并且第二电路路径用于以接收模式接收第二射频信号。 在接收模式中,第一射频信号切换到交替电路。 这可以由射频集成电路或其他控制电路来执行。 切换到备用电路路径将第一射频信号的泄漏减少到第二射频信号。

    • A receiver 650 operates in close proximity to at least one other component 610, 611, 612 causing interferences in signals received by the receiver 650. It is determined (steps 2002; 2003) whether and at which frequency a higher harmonic of and/or an inter-modulation product with signals generated by the other component 610 causes interference in signals received by the receiver 650, based on information about signals generated by the other component 610, 611, 612. At least one characteristic of the receiver 650 is adjusted to diminish an influence by a determined interference.

    • A device 22 includes a communication system transceiver 40 for exchanging signals in a first frequency band and a receiver 30 for receiving signals in a second frequency band. In order to improve the performance of the receiver. A processing portion 34 of the devices detects the presence of signals interfering with the signals in the second frequency band and also determines a timing pattern for interfering signals based on a timing information which is indicative of the timing for transmissions employed by the transceiver 40. A manipulation of signals reaching the receiver 30 during intervals defined by the determined timing pattern is then done, in order to reduce a performance degradation due to interfering signals originating from a transmitter 21 employing the same timing for transmissions as the transceiver 40. A corresponding method is also disclosed.
