Description

BACKGROUND The ‘New Radio’ (NR) terminology that is associated with fifth generation mobile wireless communication systems (“5G”) refers to technical aspects used in wireless radio access networks (“RAN”) that comprise several quality-of-service classes (QoS), including ultrareliable and low latency communications (“URLLC”), enhanced mobile broadband (“eMBB”), and massive machine type communication (“mMTC”). The URLLC QoS class is associated with a stringent latency requirement (e.g., low latency or low signal/message delay) and a high reliability of radio performance, while conventional eMBB use cases may be associated with high-capacity wireless communications, which may permit less stringent latency requirements (e.g., higher latency than URLLC) and less reliable radio performance as compared to URLLC. Performance requirements for mMTC may be lower than for eMBB use cases. Some use case applications involving mobile devices or mobile user equipment such as smart phones, wireless tablets, smart watches, and the like, may impose on a given RAN resource loads, or demands, that vary. SUMMARY The following presents a simplified summary of the disclosed subject matter in order to provide a basic understanding of some of the various embodiments. This summary is not an extensive overview of the various embodiments. It is intended neither to identify key or critical elements of the various embodiments nor to delineate the scope of the various embodiments. Its sole purpose is to present some concepts of the disclosure in a streamlined form as a prelude to the more detailed description that is presented later. In an example embodiment, a method may comprise transmitting, by a radio access network node comprising a processor to a user equipment according to a first encoding format, control channel information corresponding to a communication session between the radio access network node and the user equipment, and transmitting, by the radio access network node to the user equipment according to a second encoding format, artificial intelligence (“AI”) model information, wherein the first encoding format and the second encoding format are different. The first encoding format may correspond to, or may be indicative of, a first rate, wherein the second encoding format may correspond to, or may be indicative of, a second rate, and wherein the first rate is lower than the second rate. Thus, the control channel information may be transmitted with a higher reliability due to the slower, or lower, rate, and the larger AI model information may be delivered more quickly, but with less reliability, which may result in a need to retransmit a portion, or segment, of the AI model information. The control channel information and the artificial intelligence model information may be transmitted in a radio resource control (“RRC”) signal message. The control channel information and the artificial intelligence model information may be transmitted in a control channel message. The radio resource control signal message may comprise a radio resource control signal message format indication indicative of the first encoding format. The radio resource control signal message may comprise a radio resource control signal message format indication indicative of the second encoding format. In an embodiment, the radio resource control signal message may comprise separate format indications corresponding separately to the control information or the AI model information. In an embodiment, a single control channel message may comprise a format indication indicative of the first rate used to transmit the control information and the single control channel message may also be indicative of the second rate used to transmit the AI model information. The control channel information may be transmitted via a primary portion of the radio resource control signal message, and the artificial intelligence model information may be transmitted via a secondary portion and a tertiary portion of the radio resource control signal message. A secondary and tertiary format indication may be indicative of format, cording rates, or other parameter information used to transmit, or that are to be used to decode, information transmitted in the secondary or tertiary portions. In an embodiment, the control channel information may be transmitted via a primary portion of the radio resource control signal message, and the artificial intelligence model information may be transmitted via at least a secondary portion of the radio resource control signal message. The radio resource control signal message may comprise a first radio resource format indication indicative of a first number of control channel signal segments used to transmit the control channel information in the primary portion of the radio resource control signal message. The radio resource control signal message may comprise a second radio resource format indication indicative of second control channel signal segments us
