Abstract: An apparatus for implementing digital baseband predistortion includes a transmission channel including a digital-to-analog converter, a modulator, an amplifier and a power amplifier, and further includes a feedback channel analog part including a diode detector, a filter and an analog-to-digital converter, and a feedback channel digital part including a predistorter, a mode obtaining unit, a predistortion coefficient generator and a feedback correcting unit. The diode detector is configured to obtain an envelope of an output signal of the power amplifier. Embodiments of the present invention further provide a method for implementing digital baseband predistortion by applying the foregoing single-chip. Due to a simple structure of the diode detector, not only the number of radio frequency devices on the feedback channel is reduced, implementation complexity of hardware is lowered, power consumption is reduced, but also a feedback channel analog part may be integrated onto the single-chip.

Abstract: A port mode adaptation method includes a network device determining a status of a port on the network device. The method includes the network device setting a mode of the port to an Ethernet interface mode if the status of the port satisfies a first condition. In this way, when the network device identifies the mode of the port on the network device as the FlexE interface mode, and there is no link at the FlexE shim of the port, the network device may determine that a mode used by a port interconnected with the port is not a FlexE interface mode. In this case, the network device may adaptively set the mode of the port to the Ethernet interface mode, to ensure that the port on the network device can use a same mode as another port interconnected with the port.

Abstract: A pre-distortion coefficient corresponding to a transmit power currently set by a transmitting end is adjusted. A signal received quality report which is obtained according to the pre-distortion coefficient before adjustment is analyzed and fed back by a receiving end and a signal received quality report that is obtained according to the pre-distortion coefficient after adjustment and fed back by the receiving end. The analysis determines a variation situation of signal received quality of the receiving end. If the signal received quality of the receiving end becomes better, the pre-distortion coefficient after adjustment is used as the pre-distortion coefficient corresponding to the transmit power currently set by the transmitting end. The process then returns to the step of adjusting a pre-distortion coefficient corresponding to a transmit power currently set by a transmitting end.

Abstract: A packet measurement method includes obtaining, by a network device, reverse measurement indication information that is used to indicate a request to measure a reverse packet flow of a first packet flow, after receiving the first packet flow, adding, by the network device, the reverse measurement indication information to a packet in the first packet flow, and sending, by the network device, the packet that is in the first packet flow and that carries the reverse measurement indication information. By adding the reverse measuring indication information to the packet in the first packet flow, the method indicates a request to another network device on the packet forwarding path to measure the reverse packet flow of the first packet flow. Measurement on bidirectional packet flows is implemented through one measurement deployment.

Abstract: A data transmission method includes an access node sends first traffic to a first core network device in a core network through a first service plane of a bearer network. The access node sends second traffic to a second core network device in the core network through a second service plane of the bearer network. The first service plane and second service plane are independent all-active service planes in the bearer network. Service data sent by the base station is split on the access node, and split data each corresponds to one transmission path. Even if one transmission path is completely interrupted, the service data may still be transmitted by another core network device through the other transmission path.
