 Computation of channel state feedback in systems using common reference signal interference cancellation / 2518758
When enabled with common reference signal interference cancellation, user equipment (UE) may compute a channel state feedback value taking into account any cancelled interfering neighbouring signals. When neighbouring cells are determined to be transmitting data during the time for which the channel state feedback value is being computed, the UE is able to derive the channel state feedback value taking into account those cancelled interfering signals. The UE determines whether each neighbouring cell is transmitting during the designated time either by obtaining signals that indicate the transmission schedule of the neighbouring cells or by detecting the transmission schedule, for example based on the power class of the neighbouring cells. If the UE determines that the neighbouring cells are transmitting data during this time period, the UE will compute the channel state feedback value including consideration of the cancelled interfering signals.

FIELD: radio engineering, communication. SUBSTANCE: invention relates to communication engineering and can be used to perform functional check of a communication system in an aircraft cabin. The apparatus for functional check of a communication system comprises a control device which includes a broadband noise signal generator and a transmitter for transmitting a high-frequency signal to a radiating linear antenna, wherein functional check is performed at a power level so low that signal emission at the radiating linear antenna is lower than a given limiting value outside the cabin.

The present invention relates to a device and method for performing a functional test of a communication system, in particular in the cabin of the aircraft (LA), in particular in the field of aviation and Astronautics. Although it may be applied in any field, the present invention will be described in detail with reference to LA or passenger AIRCRAFT. Communication systems in salons LA provide communication services, such as GSM, UMTS, WLAN, and others, for the crew of LA or passengers. To send a signal for the respective service, you can use radiant linear antenna, which is arranged longitudinally in the cabin of the aircraft. To verify the correct installation and operation of communication systems, in particular, to ensure the distribution of high-frequency (HF) signal in the salon LA, perform coverage measurement (measurement of the passage of radio waves) in each frequency range of appropriate services, using the analyzer RF spectrum and measuring the antenna in several places of beauty LA. The measurement results can vary greatly depending on the condition and configuration of the beauty of LA and the choice of measurement. For this reason, the measurement results have to be averaged with the adjusted corresponding coefficients measuring antennas. In some cases, if the measurement is performed inaccurately or incorrectly, can pocasts is, specified, in particular legal, the threshold is not reached, even if this legal threshold is actually exceeded. In addition, it is possible that will receive the error message, although actually there is no error. Traditional measurements using analyzer RF spectrum and specially selected measuring antennae appropriate dimensions, unfortunately, have to be done manually, which requires a lot of time and money. Also, unfortunately, requires specially trained personnel for implementation and evaluation of traditional measurements. In particular, such trained personnel must have experience with RF measurements. In addition, traditional measurements require special equipment, for example, analyzer RF spectrum and measuring antennas. To validate at any desired place in the cabin of an aircraft typically use control RF signals, which have a power level that require legal resolution. Such legal permission is usually required because traditional control RF signals with the power levels can also be measured outside of LA and can potentially cause interference with other services. Therefore, one objective of the present invention is to provide an automated functional test of a communication system, in particular, in the cabin of the aircraft. Another one is the objective to offer an automated functional test of a communication system which does not require legal resolution. This objective is achieved in accordance with the invention by a device having the characteristics in paragraph 1, and by the way, with signs on paragraph 16 of the claims. Accordingly, the proposed device to perform a functional test of a communication system, in particular, in the salon of LA, which includes: - transmission channel that includes at least one transmitting linear antenna, located in the salon LA; - the control unit, which is connected with the transmission channel and includes a generator for generating broadband noise signal and a transmitter for feeding an RF signal for transmitting linear antenna with the supplied RF signal has a specified power level and includes at least the broadband noise signal; at least one meter, which is connected at a certain point of connection to the transmission channel for measuring the power level of the RF signal at the connection point and for supplying the measuring signal, which is proportional to the measured power level; and - assessment tool for obtaining a test result by comparing the submitted measurement signal with the control signal, which depends on the power level filed RF signal. In addition, a method for performing a functional test of a communication system, in particular, in the cabin of aircraft which includes the following steps: - generation of broadband noise signal; - submission of the RF signal in the transmission channel, which includes at least one transmitting linear antenna, located in the beauty of LA, and filed RF signal has a specified or set the power level and includes at least the generated broadband noise signal; - measurement of the power level at a certain point of connection of the transmission channel; - submission of the measuring signal, which is proportional to the measured power level; and - receipt of the test result by comparing the submitted measurement signal and the control signal, which depends on the power level filed RF signal. The advantage of the present invention is that the functional test in accordance with the invention, a communication system can be performed without additional special RF measurement device, such as the analyzer RF spectrum, and without the use of specially trained personnel, since all the necessary components of the device can be integrated into the communication system. In the device according to the invention the functional test of a communication system can also be run is s simple push of a button which includes the device, and can be performed fully automatically. At the end of the function test, the user may be signaled as a function of the test result. For example, the verification may include an error message or error code. Another advantage of the present invention lies in the fact that it is possible not to perform the traditional manual measurement in the cabin of an aircraft with a subsequent conventional processing of data validation. In particular, the measurement result is transmitted through the transmitting linear antenna and the probe at a certain point of connection, for example, at the end of the transmission channel, the test result according to the invention oscillations influence smaller than the results of traditional tests, so there is more good reproducibility and hence higher reliability. As a result of use of the device according to the invention and the method according to the invention perform functional validation errors in installation, such as forgotten jumpers or connections, breaks in lines or damage to the linear radiating antenna can be clearly and quickly installed. The measurement is transmitted through the transmitting linear antenna also allows in combination with the use of the meter, at least one particular connection point is the anal transfer to reduce the power level of the RF signal, required for the function test to the level, which makes redundant the request for the allocation of frequencies used in the test, and therefore legal permission. Function test according to the invention thus can be performed in any desirable place in the world and does not require legal permission from the relevant national authorities. The device according to the invention also is configured to control and, optionally, adjustment and efficiency of the communication system, in particular with a relatively high floor for inspection and during operation of the communication system. For example, the power level of signals transmitted by transmitting linear antenna can be adjusted. Preferred embodiments of and improvements of the invention are described in dependent claims. In accordance with a preferred configuration of the invention, the supplied noise signal is broadband compared to band coherence of the transmission channel. In the framework of this application band coherence W is determined by the autocorrelation function in the frequency-time φFT (Δf, Δt=0) the transfer function of the channel: |φFT(Δf=Wc, Δt=0)|=1/2|φFT(Δf=0, Δt=0)| Band coherence Wc is the value at which the value of the autocorrelation function in the frequency-time with increasing Δf first falls napolo the inu. Therefore, it is a measure of the difference frequency Δf, in which two sinusoidal signal must vary to have completely different properties of the transmission channel during transmission. If the range signal W is smaller than band coherence Wc, all part of the spectrum of the signal will be essentially identical transmission properties. Therefore, band coherence W approximately indicates the maximum frequency interval, in which two frequency components of the signal are comparable or correlated loss of amplitude. If the variance of the signal in time (multipath dispersion or variation with time delay)caused by multipath dispersion on the radio channel is D seconds, the following is approximately true for band coherence Wc in Hz: Wc≈1/(2*Pi*D).
