Methods and apparatuses for radio communication

An apparatus, including a radio terminal or user equipment or a module of a radio terminal or user equipment, comprising:

• at least one processor configured to:
• determine at least one downlink channel quality associated with at least one downlink channel;
• determine, based at least on the at least one downlink channel quality, at least one future downlink channel quality indicator that characterizes an estimated future quality associated with the downlink channel;
• determine, based at least on the at least one monitored downlink channel quality, at least one estimation quality indicator that characterizes an estimation quality of the at least one associated future downlink channel indicator;
• determine, via a machine-trained downlink-embedding function, a first latent code based on the at least one downlink channel quality;
• determine, via a machine-trained assisting-data embedding function, a second latent code based on assisting data;
• and
• determine, via a machine-trained prediction function, the at least one future downlink channel indicator and the least one estimation quality indicator based at least on the first latent code and/or the second latent code;
• a transmitter configured to transmit the at least one estimation quality indicator;
• and
• a transmitter configured to transmit the at least one future downlink channel quality indicator.

A method, comprising the following steps:

• receiving at least one future downlink channel quality indicator that characterizes an estimated future quality associated with a downlink channel;
• receiving at least one estimation quality indicator that characterizes an estimation quality of the at least one associated future downlink channel indicator;
• determining at least one transmission parameter based at least on the received at least one future downlink channel quality indicator and based on the at least one estimation quality indicator;
• and
• transmitting, via the downlink channel, downlink data in accordance with the determined at least one transmission parameter,
• wherein the at least one future downlink channel indicator and the at least one estimation quality indicator are determined based at least on a first latent code and/or a second latent code, the first latent code determined based on at least one downlink channel quality and the second latent code determined based on assisting data.

An apparatus including a radio access node of a radio access network or a module of the radio access node, comprising:

• a processor configured to determine at least one transmission parameter based at least on the received at least one future downlink channel quality indicator and based on the at least one estimation quality indicator;
• and
• a transmitter configured to transmit, via the downlink channel, downlink data in accordance with the determined at least one transmission parameter,
• wherein the at least one future downlink channel indicator and the at least one estimation quality indicator are determined based at least on a first latent code and/or a second latent code, the first latent code determined based on at least one downlink channel quality and the second latent code determined based on assisting data.
