name: PBCH
full_form: Physical Broadcast Channel
context: The ControlResourceSetId IE concerns a short identity, used to identify a control resource set within a serving cell. The ControlResourceSetId = 0 identifies the ControlResourceSet#0 configured via PBCH (MIB) and in controlResourceSetZero (ServingCellConfigCommon). The ID space is used across the BWPs and MBS CFRs of a Serving Cell. ControlResourceSetId information element -- ASN1START -- TAG-CONTROLRESOURCESETID-START ControlResourceSetId ::= INTEGER (0..maxNrofControlResourceSets-1) ControlResourceSetId-r16 ::= INTEGER (0..maxNrofControlResourceSets-1-r16) ControlResourceSetId-v1610 ::= INTEGER (maxNrofControlResourceSets..maxNrofControlResourceSets-1-r16) -- TAG-CONTROLRESOURCESETID-STOP -- ASN1STOP
description: The Physical Broadcast Channel (PBCH) is a downlink channel in the Long Term Evolution (LTE) and New Radio (NR) networks, used for broadcasting system information from the eNodeB or gNB to user equipment. It carries essential data such as the Master Information Block (MIB), which includes critical parameters like the cell identity and configuration details necessary for UE initialization and network access.
explanation: PBCH is classified as a Channel because it refers to a specific path used for transmitting control information from the base station to user equipment in LTE and NR networks, aligning with the context of radio resource control and protocol specifications provided by 3GPP TS 38.331.
