Summary based on the input provided by EBU, Qualcomm Incorporated in RP-220445.
Before Rel-17, 5G terrestrial broadcast only supports the same system bandwidths as traditional LTE (1.4, 3, 5, 10, 15, 20MHz). Broadcast UHF spectrum, however, is channelized typically in channels of 6/7/8MHz (depending on the region). The objective of this work item [1] is to introduce support of PMCH bandwidths of 6/7/8MHz in MBMS-dedicated cells to enable deployment of 5G terrestrial broadcast in broadcast UHF spectrum.
The detailed operation to enable the above feature is as follows:
  • The eNB indicates in MIB a system bandwidth of 5MHz (25PRBs) or 3MHz (15PRBs).
  • In system information, the eNB indicates, per MBSFN area, whether the PMCH in that MBSFN area uses a bandwidth larger than the system bandwidth. The possible values for this bandwidth are 6MHz (30PRBs), 7MHz (35PRBs) and 8MHz (40PRBs).
  • The PMCH and MBSFN-RS are received with the indicated bandwidth.
A figure depicting the operation is shown below:
