    摘要: The present invention provides a processing method based on an OFDM-TDMA two-way service and a communications device. The method includes: assigning timeslots in a TDMA frame structure to multiple users in a TDMA manner, so that each user has a different timeslot, and each timeslot of the users is simultaneously used for uplink and downlink communication; simultaneously sending a local-end OFDM signal and receiving a remote-end OFDM signal in each timeslot of the users; and cancelling, in an OSD manner, interference caused by an echo OFDM signal, which is produced according to the local-end OFDM signal, to the remote-end OFDM signal, where a spectrum of the echo OFDM signal and a spectrum of the remote-end OFDM signal overlap.

    摘要: The present invention provides a crosstalk estimation method, an apparatus, and a system. According to the crosstalk processing method, the apparatus, and the system provided in embodiments of the present invention, a transceiver of a line generates, respectively according to pilot sequences allocated by a vectoring control entity, pilot training signals that are within different spectral ranges and that satisfy a preset relationship with a pilot training signal of another line, so that a receiver of the line can determine sample errors respectively according to the different pilot training signals. Then, the vectoring control entity determines crosstalk channel coefficients from the another line into an inband spectrum and an out-of-band spectrum of the line, and performs precoding processing on a to-be-sent data signal of the line, so as to eliminate impact of crosstalk from the another line to the inband and out-of-band spectrums of the line. This reduces impact on a line rate caused by inter-line crosstalk in a system in which lines of different profiles coexist, and further improves effects and stability of FTTC acceleration.

    摘要: A method and a network apparatus for adjusting communication resources in a community are disclosed. When the topological structure of the community changes, e.g. when new base station joins or exits, and when the community combines or splits, each base station re-allocates the communication resources by using a uniform algorithm, or the server or one base station in the community re-allocates the communication resources uniformly, then the base stations in the community are adjusted to the their own available resource at the same time based on the re-allocation results. The communication resources includes not only the frequency spectrum, but also those are exclusively occupied by a base station required by its normal operation, e.g. time slot, CDMA code word, sub-channel etc. With the invention, the automatic optimum allocation and adjustment of the communication resources in a community could be realized.
