Abstract: A method, system, network and device provide Smart Grid RFI detection. One or more symbols or chips present in one or more received radio frequency signals are detected and the presence of one or more erred symbols or chips in the detected one or more symbols present in the received one or more radio frequency signals determined. A correlation in time between the one or more erred symbols or chips and an infrastructure waveform associated with electrical infrastructure can be determined. When the determined correlation indicates the electrical infrastructure as a source of detectable radio frequency interference to a device, a pattern flag is generated. The pattern flag or pattern flag representation can be stored and/or transmitted.

Abstract: The present invention relates to ACK-NACK detection in an LTE wireless communication system. To determine a threshold value for an ACK-NACK transmission, an SC-FDMA signal is received from user equipment. Then, a power estimate of soft data bits is used to establish a threshold value for determining the presence of an ACK-NACK signal. Using this threshold value, a signal from the user equipment is analyzed to determine if it contains an ACK or NACK transmission.

Abstract: In the field of mobile telecommunications, a method for checking a false alarm is provided. In the method, after a user in a Long Term Evolution (LTE) system receives control signaling for scheduling physical resources, Cyclic Redundancy Check (CRC) is performed on the control signaling; and if the CRC is passed, false alarm check is performed on the control signaling according to false alarm check bit(s) and padding bit(s) in the control signaling. An apparatus and a user equipment (UE) for checking a false alarm are also provided. According to the method, the apparatus, and the UE for checking a false alarm, the number of bits participating in the false alarm check is increased, thereby reducing the probability of false alarm occurrence, and improving receiving performance of the control signaling.

Abstract: A method and apparatus for supervising a dedicated control channel when in the discontinuous transmission mode. The mobile station monitors the frames it receives from a base station and maintains a counter of bad, good, and empty frames, referred to as CNT1, CNT2, CNT3, respectively. If a received frame is a good frame, CNT1 is reset to zero and CNT2 is incremented. If the received frame is a bad frame, CNT1 is incremented and CNT2 is reset to zero. If the received frame is an empty frame, CNT1 and CNT2 are unchanged but CNT3 is incremented. A transmitter coupled to the mobile station is enabled or disabled depending upon which, if any, of the CNTs reaches or exceeds a designated threshold value. In another embodiment, an average aggregated value reflecting the strength of the pilot signals in an active set, measured at the mobile station, is used for comparison to a threshold.

Abstract: Methods, algorithms, architectures, circuits, and/or systems for managing POR-less integrated circuits are disclosed. The method of validating code from a wireless device can include: (i) broadcasting a signal from a reader to the wireless device, (ii) reading a code transmitted, re-radiated, and/or backscattered from the wireless device, the code having a predetermined quality, characteristic, and/or property, (iii) comparing the code to a reference quality, characteristic, and/or property, and (iv) validating the code when the predetermined quality, characteristic, and/or property matches the reference quality, characteristic, and/or property. Embodiments of the present invention can advantageously provide a reliable approach for validating integrated circuits that do not incorporate a POR circuit, and which therefore may transmit spurious bits of data upon being energized. In addition, embodiments of the present invention advantageously allow an Aloha-type anti-collision function to be implemented in a reader based on POR-less integrated circuits.

Abstract: The exemplary embodiments of this invention relate in part to an apparatus that includes an error correction function and a controller configured to receive radio access scheduling information in response to a scheduling request sent to a multiradio controller. The controller is responsive to the radio access scheduling information containing an indication of a time when during a scheduling interval reception is blocked for a receiver of the apparatus, due at least in part to simultaneously scheduled operation of a transmitter, to send information to the error correction function for marking as erased any symbols received during a time that the reception is indicated to be blocked. The exemplary embodiments of this invention may be realized at least in part in a software defined radio platform that includes the multiradio controller and a plurality of radio access units.

Abstract: A method for dynamically adjusting the power consumption of a multi-carrier receiver and a multi-carrier receiver with dynamically power adjustment. The method includes receiving a multi-carrier signal, wherein the multi-carrier signal comprises a plurality of sub-carriers. Channel characteristics of each sub-carrier are estimated according to the demodulated multi-carrier signal. ICI strength is estimated from the demodulated multi-carrier signal. A system performance is detected. The estimated ICI is subtracted when the ICI strength exceeds an ICI threshold and the system performance is less than a system performance threshold. The demodulated multi-carrier signal is then equalized is based on the estimated channel characteristics, and the system performance is updated according to the equalized multi-carrier signal.

Abstract: A received information signal is decoded to obtain the received information and to produce at least one feature of the received information signal. The received information signal is preliminarily classified as containing a normal burst or a truncated burst based upon the at least one feature, to obtain a preliminary classification. Cyclic redundancy checking of the received information that is decoded is performed. The received information signal is then further classified as containing a normal burst or a truncated burst based upon the preliminary classification and whether the cyclic redundancy checking is valid, to obtain a further classification. The received information signal may be still further classified as containing a normal burst or a truncated burst based upon the further classification and at least one transition rule for normal bursts and truncated bursts between the received information signal and a previously received information signal.
