Method and apparatus for training a full-duplex communication link

A first communication device, comprising:

• a transceiver configured to communicate via a full-duplex communication link;
• a controller configured to:
• receive, during a training procedure for communicating via the full-duplex communication link, training information from a second communication device, the training information corresponding to first signal processing parameters developed at the second communication device for use by the second communication device to process signals received by the second communication device via the full-duplex communication link, and
• use the training information to determine initial values of at least some second signal processing parameters for use by one or more signal processors of the first communication device;
• and
• the one or more signal processors of the first communication device being configured to:
• adapt the at least some second signal processing parameters from the initial values during the training procedure, the initial values having been determined using the training information received from the second communication device, and
• process signals received via the full-duplex communication link based on the adapted at least some second signal processing parameters.

A first communication device, comprising:

• a transceiver configured to communicate via a full-duplex communication link;
• one or more signal processors configured to:
• develop, during a first portion of a training procedure for communicating via the full-duplex communication link, first signal processing parameters to be used by the one or more signal processors to process signals received by the first communication device via the full-duplex communication link;
• and
• a controller configured to:
• determine training information corresponding to the first signal processing parameters, and
• control the transceiver to transmit the training information to a second communication device, the training information transmitted by the first communication device to be used by the second communication device in a second portion of the training procedure to develop second signal processing parameters to be used by the second communication device when communicating with the first communication device via the full-duplex communication link.
