    en.wikipedia.org/wiki/Radio_Resource_Control

    The Radio Resource Control (RRC) protocol is used in UMTS, LTE and 5G on the Air interface. It is a layer 3 (Network Layer) protocol used between UE and Base Station. This protocol is specified by 3GPP in TS 25.331 [2] for UMTS, in TS 36.331 [3] for LTE and in TS 38.331 [4] for 5G New Radio. RRC messages are transported via the PDCP-Protocol.

    en.wikipedia.org/wiki/Radio_Bearer_in_UMTS

    In mobile telephony a bearer service is a link between two points, which is defined by a certain set of characteristics. Whenever user equipment (UE) is being provided with any service (CS/PS service), the service has to be associated with a Radio Bearer specifying the configuration for layer 2 and physical layer in order to have its QoS clearly defined.

    en.wikipedia.org/wiki/GSM-R

    GSM-R is a TDMA ("Time-Division Multiple Access") system. Data transmission is made of periodical TDMA frames (with a period of 4.615 ms), for each carrier frequency (physical channel). Each TDMA frame is divided in 8 time slots, named logical channels (577 μs long, each time-slot), carrying 148 bits of information.
