full_form: System Information Block 1
context: When RRC (TS 38.331 [3]) configures an UL QoS flow to DRB mapping rule for a QoS flow, the SDAP entity shall: - if the SDAP entity has already been established and there is no stored QoS flow to DRB mapping rule for the QoS flow and a default DRB is configured: - construct an end-marker control PDU, as specified in the clause 6.2.3, for the QoS flow; - map the end-marker control PDU to the default DRB; - submit the end-marker control PDU to the lower layers. - if the stored UL QoS flow to DRB mapping rule is different from the configured QoS flow to DRB mapping rule for the QoS flow and the DRB according to the stored QoS flow to DRB mapping rule is configured by RRC (TS 38.331 [3]) with the presence of UL SDAP header: - construct an end-marker control PDU, as specified in the clause 6.2.3, for the QoS flow; - map the end-marker control PDU to the DRB according to the stored QoS flow to DRB mapping rule; - submit the end-marker control PDU to the lower layers. - store the configured UL
description: System Information Block 1 (SIB1) is a type of message in the 5G New Radio (NR) system, which carries essential system information to user equipment. It is transmitted periodically and can be multiplexed with other signals like SS/PBCH blocks. The transmission configurations for SIB1 are defined, including its periodicity, mapping, and accommodation within slots.
explanation: SIB1 is classified as a Message because it is described as being transmitted, multiplexed, and having specific transmission configurations. These characteristics indicate that SIB1 functions as a signaling message used in communication between the network and user equipment.
