    摘要: Systems and methods applicable, for instance, in wireless communications. For example, a wireless node and/or other computer may act to create a candidate signal list and/or may act to measure strength for one or more candidate list signals. As another example, the wireless node and/or other computer may act to calculate average difference between the strength of the strongest signal of the candidate list and the strength of a currently-received signal. As yet another example, the wireless node and/or other computer may act to perform one or more operations to employ the strongest signal of the candidate list in place of the currently-received signal.

    摘要: Provided are apparatuses and methods for detecting neighboring cells in a communication network based on Transmission Parameter Signaling (TPS) bits received in a signaling frame. In one example, a signaling frame contains a field of TPS bits that indicate a type of the signaling frame. The type of the signaling frame may indicate the information carried in the signaling frame as information of a current cell or a neighboring cell. The signaling frame may further include information from a neighboring cell in the same network or a different network as the current cell. The signaling frame may further be arranged in a superframe in which the a plurality of frames are transmitted to a receiver in a certain sequence. Each frame in a superframe or a sequence of frames may include a parameter for defining the location of the frame.

    摘要: A method, a system, a transmitter and a receiver for identification of a time sliced elementary streams using PSI/SI tables. This identification provides a way to separate time-sliced elementary stream from non-time-sliced elementary streams by defining two descriptors in PSI/SI tables. A time slice identifier descriptor is defined, which can be used to identify elementary streams which are time sliced. This descriptor is also used to provide additional information about the transmitted elementary streams. The invention provides a way to announce additional information of the time sliced elementary streams via PSI/SI tables. Additionally, it provides a mechanism to categorize single elementary stream(s) as non-time sliced and time sliced. A way to identify time sliced elementary streams carried over DVB networks is disclosed and providing additional information on those streams. This can be done by using the time slice identifier descriptor. The descriptor can be used at least in Network Information Table (NIT), Program Map Table (PMT) and IP/MAC Notification Table (INT) tables. Time slicing provides a way to save power in the receiver in broadband transmission.

    摘要: The invention relates to a method for adjusting IQ-imbalance of a direct conversion receiver (200). In the method a radio frequency training signal is locally generating and conveyed to an in-phase branch and a quadrature-phase branch of the receiver (200). The method comprises mixing, in the analogue domain, the radio frequency training signal of the in-phase branch with a first mixing signal to form a baseband in-phase component (I) of the training signal and mixing, in the analogue domain, the radio frequency training signal of the quadrature-phase branch with a second mixing signal to form a phase shifted component (Q) of the training signal. The baseband in-phase component (I) and phase shifted component (Q) are analogue-to-digital converted to form a digital baseband in-phase component and a digital baseband phase shifted component of the training signal. In the method the digital baseband in-phase and phase shifted components of the training signal are analyzed, in a digital demodulator (210), so as to detect the IQ-imbalance of the direct conversion receiver (200). The IQ-imbalance is corrected, based on the analysis, in the analogue domain.

The second communication channel may be with a station logically separated from the base station. The base station maybe configured to respond to the indication of the occurrence of the irregular transmission by modifying transmission on the first communication channel to avoid interfering with the irregular transmission. The method may additionally include causing transmission, to the base station, of an indication of completion of the irregular transmission to allow the base station to resume normal transmission on the first communication channel. Corresponding apparatuses and systems are also provided.
