Methods and apparatus for providing a demapping system with phase compensation to demap uplink transmissions. In an embodiment, a method is provided that includes detecting a processing type associated with a received uplink transmission, and when the detected processing type is a first processing type then performing the following operations: removing resource elements containing reference signals from the uplink transmission; layer demapping remaining resource elements of the uplink transmission into two or more layers; phase compensating all layers to generate phase compensated layers; and soft-demapping all phase compensated layers to produce phase compensated soft-demapped bits.

This application is directed to transferring data over a data link coupled between two electronic devices. The data link includes a retimer having a full data path and a bit level data path that are coupled in parallel. The data link is initiated with the full data path and a first sequence of data packets is transferred via the full data path in accordance with a low data rate setting. While transferring the first sequence of data packets, the first sequence of data packets is manipulated in the full data path to establish a connection of the data link, and in response to establishing the connection of the data link, the data link is switched from the full data path to the bit level data path.
