摘要： There is provided a method comprising sending, to a device with multi receiver chains, a first test signal at a first angle of arrival at the device; whilst the first test signal is being sent, sending at least one additional test signal to the device at at least one additional angle of arrival that has an angular difference to the first angle of arrival; measuring at least one performance metric of the device whilst the device is receiving the first test signal and the at least one additional test signal; and comparing the at least one performance metric to at least one corresponding requirement value, the requirement value being dependent on the angular difference between the at least one additional angle of arrival and the first angle of arrival.

摘要： Systems, methods, apparatuses, and computer program products for reporting by a user equipment of maximum sensitivity degradation and relaxation values thereof. A method comprises receiving a request message related to capability of the apparatus, wherein the request message includes maximum sensitivity degradation information of the apparatus corresponding to an operational situation of the apparatus; responding to the request message with a response message, wherein the response message indicates the maximum sensitivity degradation value corresponding to said operational situation of the apparatus; and utilizing self-measurements during said operational situation of the apparatus to determine a new maximum sensitivity degradation value which replaces the current maximum sensitivity degradation value corresponding to the operational situation of the apparatus.

摘要： An apparatus comprising:
power amplifier circuitry;
proximal filter circuitry proximal to the power amplifier circuitry;
means for routing output of the power amplifier circuitry to the proximal filter circuitry to be filtered for transmission;
means for routing output of the power amplifier circuitry to remote filter circuitry remote from the power amplifier circuitry to be filtered for transmission;
wherein the proximal filter circuitry is configured to provide for transmission in a transmission bandwidth of a first band, reception in a reception bandwidth of the first band and reception in a reception bandwidth of the second band and comprises
a proximal duplexer configured for the transmission bandwidth of the first band and the reception bandwidth of the first band, a proximal bandpass filter for the reception bandwidth of the second band and a proximal diplexer for isolating the transmission bandwidth of the first band and the reception bandwidth of the second band.
