Systems and methods for online learning of joint receiver functions for demodulation

A wireless transmit/receive unit (WTRU) comprising a processor, the processor configured to:

• receive configuration information, the configuration information comprising an indication of a first receiver function training allocation type, a second receiver function training allocation type, or a third receiver function training allocation type, wherein the first receiver training allocation type is associated with user data allocations, the second receiver training allocation type is associated with pseudo-random data (PRD) allocations, and third receiver function training allocation type is associated with user data allocations and PRD allocations;
• receive a downlink transmission that comprises at least one of data allocations or PRD allocations;
• generate labels based on the received downlink transmission, wherein, when the configuration information comprises the first receiver function training allocation type, the labels are generated using the received data allocations, and wherein, when the configuration information comprises the second receiver function training allocation type, the labels are generated using the received PRD allocations, and wherein, when the configuration information comprises the third receiver function training allocation type, the labels are generated using both the received data allocations and the received PRD allocations;
• and
• send a status message to a network, the status message comprising an indication of whether training is complete.
