Claim Text:
1. An access node for digital subscriber line (DSL) communication comprising: a transceiver configured to couple a subscriber line; and a control entity coupled to the transceiver, wherein the control entity is configured to: wherein the subscriber line comprises a wired connection, wherein the TDD frame structure comprises a fixed downstream time period and a fixed upstream time period, wherein the fixed downstream time period indicates a minimum time period allocated for the downstream transmission, wherein the fixed upstream time period indicates a minimum time period allocated for the upstream transmission, and wherein the fixed downstream time period is used by a receiver at a customer premise equipment (CPE) for signal-to-noise ratio (SNR) measurements, and wherein the upstream time period is used by the receiver at the access node for SNR measurements, and wherein the fixed upstream time period is used by the control entity at the access node for updating a plurality of pre-coder coefficients in the transceiver, and wherein the fixed downstream time period is used by the control entity at the access node for updating a plurality of canceller coefficients in the transceiver.
