8.5.43 Reception of MBMS from a cell operating in MBSFN mode

25.3313GPPProtocol specificationRadio Resource Control (RRC)Release 17TS

A cell provides MBMS service in MBSFN mode if it is indicated so in system information, see subclause 8.1.1.6.3. A UE that supports MBSFN operation may receive MBMS services via a cell operating in MBSFN mode. For FDD, 3.84 Mcps TDD IMB and 3.84/7.68 Mcps TDD in order to receive an MBMS service via a MBSFN cluster the UE shall select the MBSFN cluster as specified in [4] in addition to selecting a cell for normal camping as specified in [4]. For 1.28 Mcps TDD in order to receive an MBMS service via an MBSFN cluster the UE shall at the first step camp on a unicast cell and get the frequency and "cell parameter ID" from the system information, and then get synchronized to the MBSFN cluster operating with that frequency and "cell parameter ID". For 3.84/7.68 Mcps TDD a cell shall be considered to be operating in MBSFN mode when individual scrambling codes are assigned to all timeslots (via the IE "TDD MBSFN Information").

For 3.84 Mcps TDD IMB, MBMS reception is provided on a 3.84 Mcps TDD frequency [22]. The S-CCPCH frame type 2 format shall be used for the S-CCPCHs carrying MTCH. Unless specified otherwise, the RRC protocol is operated according to the FDD requirements applicable for MBSFN.
