Abstract: Embodiments of the present invention provide a line initialization method, a device, and a system. The method includes: when a new line is added, releasing at least one resource unit that is on a line at a Showtime stage, so that on the line at the Showtime stage data is transmitted on a remaining resource unit that is obtained after the at least one resource unit is released; performing basic initialization on the new line by using the at least one resource unit or a subset of the at least one resource unit, so that after the basic initialization, data can be transmitted on the new line by using the at least one resource unit or the subset of the at least one resource unit; and performing crosstalk cancellation initialization on the line at the Showtime stage and the new line by using all resource units.

Abstract: A resource scheduling method and apparatus in a DSL system, and a system are provided, to reduce energy consumption of the DSL system. The method includes: determining, according to service traffic information of each subscriber line and transmission capability information of each subscriber line, a transmission opportunity initial value allocated to each subscriber line in a TDD frame; and according to the transmission opportunity initial value of each subscriber line, dividing the TDD frame into a normal operation interval and a discontinuous operation interval, determining a transmission opportunity occupied by each subscriber line in the normal operation interval, and determining a subscriber line group in the discontinuous operation interval and a transmission opportunity occupied by each subscriber line group in the discontinuous operation interval.

Abstract: Embodiments of the present invention provide a signal processing method in a DSL system. The method includes: determining that there is no to-be-sent downstream signal on m subscriber lines in n subscriber lines; superimposing a signal X on the m subscriber lines, so that a signal output on the m subscriber lines after precoding processing is 0, where xm indicates a signal component loaded on the mth subscriber line in the m subscriber lines; performing precoding processing on a downstream signal on the n subscriber lines; and sending the downstream signal that has undergone the precoding processing on another line except the m subscriber lines in the n subscriber lines. The embodiments of the present invention further provide a network-side device and a DSL system.
Abstract translation: 本发明的实施例提供了DSL系统中的信号处理方法。 该方法包括：确定在n个用户线路中的m个用户线路上没有不发送的下行信号; 在m个用户线路上叠加信号X，使得在预编码处理之后在m个用户线路上输出的信号为0，其中xm表示在m个用户线路中的第m个用户线路上加载的信号分量; 对n个用户线路上的下行信号进行预编码处理; 并且在n个用户线路中除了m个用户线路之外的另一个线路上发送经过预编码处理的下行信号。 本发明的实施例还提供一种网络侧设备和DSL系统。
