Medium access control-control element (MAC-CE) communication

An apparatus for wireless communication, comprising:

• at least one processor;
• and
• at least one memory communicatively coupled with the at least one processor and storing processor-readable code that, when executed by the at least one processor, causes the apparatus to:
• transmit control signaling indicating whether a packet to be transmitted comprises data;
• generate the packet including generating at least one medium access control-control element (MAC-CE) in the packet;
• transmit the packet including the at least one MAC-CE;
• receive hybrid automatic request (HARQ) signaling indicating whether the packet was decoded successfully, whether a retransmission of the at least one MAC-CE is required when the packet comprises the data, and that a retransmission of the at least one MAC-CE is not required when the packet does not comprise the data;
• and
• transmit another packet comprises the retransmission of the at least one MAC-CE or at least one other MAC-CE in accordance with the HARQ signaling.

A method for wireless communications, comprising:

• receiving a packet including at least one medium access control-control element (MAC-CE);
• determining whether the packet further comprises data;
• generating hybrid automatic request (HARQ) signaling indicating whether the packet was decoded successfully, whether a retransmission of the at least one MAC-CE is required when the determination is that the packet further comprises the data, and that a retransmission of the at least one MAC-CE is not required when the determination is that the packet does not further comprise the data;
• transmitting the HARQ signaling;
• and
• receiving another packet including the retransmission of the at least one MAC-CE or at least one other MAC-CE in accordance with the HARQ signaling.
