摘要： A wireless communication node (10) dynamically estimates passive intermodulation (PIM) interference coupled into the node's receive path from the transmission of a composite signal through the node's transmit path. The node (10) then cancels the estimated PIM interference in the receive path. In some embodiments, the node dynamically estimates the PIM interference as a function of the composite signal that models PIM interference generation and coupling in the node (10) according to one or more coefficients (30). The coefficients (30) may be determined by transmitting a test signal (34) during a test stage, when the node (10) is not scheduled to receive any signal. Later, when the composite signal (18) is transmitted, the node (10) uses the coefficients (10) to dynamically estimate and cancel the resulting PIM interference.

摘要： Error vector magnitude (EVM) is pooled and adaptively distributed among carriers in a multi-standard or multi-carrier system to reduce peak to average power ratios (PAPR) without exceeding EVM limits. Correction tone injection is used to reduce PAPR. The amplitude of each correction tone, and number of correction tones assigned to a carrier, are adjusted to control the EVM and out-of-band distortion of each carrier, to comply with EVM limits imposed by the respective radio access technology.

摘要： A wireless receiver utilizes a single analog oscillator to down-convert multi-carrier signals in one or more receiver front-end paths. The received signals are digitized, and the different carrier signals received at each antenna are separated in digital domain by mixing the digitized signal from each antenna with a carrier/antenna separation digital oscillator to down-convert a desired carrier signal and low-pass filtering to remove unwanted carriers. A coarse frequency correction adjusts the analog oscillator, and fine frequency corrections adjust digital oscillators mixing with the separated signals. In one embodiment, the fine frequency correction is applied to the carrier/antenna separation digital oscillators in the separation function. In another embodiment, the fine frequency correction is applied to frequency adjustment digital oscillators mixing with the separated signals. The frequency corrections may be based on reference symbols in the received signals.

摘要： Embodiments herein include a method and a network node in a wireless communications network for controlling a maximum output power of the network node. The network node comprises a Global Navigation Satellite System (GNSS) receiver. The GNSS receiver receives signals from the GNSS. The method comprises determining whether a GNSS signal transmitted from the GNSS is considered detectable. If the GNSS signal is considered detectable, the method includes determining whether the GNSS signal is received directly from the GNSS or via a GNSS repeater. The method further includes selecting a power control method for controlling the maximum output power of the network node, based on at least one of the determination of whether the GNSS signal is considered detectable, and the determination of whether the GNSS signal is received directly from the GNSS or via the GNSS repeater.
