name: SL-DRB
full_form: Sidelink Data Radio Bearer
context: OTD = (OTDHNB - OTD MNB) represents a HNBâs timing with respect to a macro cell (MNB) as measured by the UE where OTDcell is the timing of a UE with respect to a given cell [25]. The HNB-GW keeps a database of the OTD values for HNBs under its control and their neighbour MNB cells. The HNB-GW also keeps the mapping of a MNBâs Cell ID and its PSC. The HNB-GW updates the OTD database by using the information provided by the UEs during handovers to MNB cells. During these hand-outs, a HNB includes the MEASUREMENT REPORT message (MRM) in the RRC transparent container which is sent in the RANAP Relocation Required message and set the Target Cell Id IE to the ID of the macro cell with respect to which the OTD is computed.
description: The Sidelink Data Radio Bearer (SL-DRB) is a channel used for sidelink communication in NR (New Radio) systems. It carries data between user equipment (UE) and the network, specifically for unicast transmissions. The SL-DRB is configured by the RRC (Radio Resource Control) entity and is associated with a specific PC5 QoS flow. When an SL-DRB mapping rule is established, the SDAP (Service Data Adaptation Protocol) entity constructs an end-marker control PDU and maps it to the default SL-DRB or the stored SL-DRB according to the configured PC5 QoS flow to SL-DRB mapping rule.
explanation: SL-DRB is classified as a Channel because it facilitates data transmission between network entities. Its primary function is to carry sidelink communication data, aligning with the definition of a channel as a medium for signal transfer.
