Patent number: 10404429Abstract: Implementations related to updating channel adaptation parameters are described. In one implementation, an R2T frame, such as an acknowledgment (ACK) frame, is modified to carry a partial bit allocation table (BAT). The R2T frame may be received by a transceiver apparatus and the partial BAT carried in the header or extended header(s) of R2T frame may be used to update a BAT stored in the transceiver. In another implementation, a message frame is modified to carry a partial BAT. The message frame may be received by a transceiver apparatus and the partial BAT used to update a BAT stored in the transceiver. A unique identification number generated by the receiving transceiver apparatus may be used to synchronize BATs stored in two communicating transceivers without necessity of exchanging additional control messages.Type: GrantFiled: May 4, 2017Date of Patent: September 3, 2019Assignee: Lantiq Deutschland GmbHInventors: Joon Bae Kim, Patrick Kelliher
