name: BH
full_form: Backhaul
context: IAB-donor Topology Indicator IE in F1AP if configured, - an ingress BH RLC channel ID, which is indicated by Ingress BH RLC CH ID IE, or by the BH RLC CH ID IE in UE-associated F1AP message for upstream, and, - an egress BH RLC channel ID, which is indicated by Egress BH RLC CH ID IE, or by the BH RLC CH ID IE in UE-associated F1AP message for downstream. For a BAP Data PDU received from an ingress BH RLC channel of an ingress link and for which the egress link has been selected as specified in clause 5.2.1.3: - if there is an entry in the BH RLC Channel Mapping Configuration, whose ingress BH RLC channel ID matches the BAP Data PDU's ingress BH RLC channel, whose ingress link ID matches the BAP Data PDU's ingress link, and whose egress link ID corresponds to the selected egress link; - select the egress BH RLC channel corresponding to egress BH RLC channel ID of this entry; - else: - select any egress BH RLC channel on the selected egress link;
description: Backhaul (BH) refers to a part of a telecommunications network, specifically the connection between the core network and the cell site or tower. It is responsible for carrying data traffic from the cell site to the core network and vice versa.
explanation: The context mentions BH RLC Channel and BH RLC CH ID IE, indicating that Backhaul is related to a specific channel or link in the network. The text also discusses mapping and configuration of BH channels, suggesting that BH is a component of the network infrastructure.
