Abstract
A method of a user equipment (UE) in a wireless communication system comprises receiving, from a base station (BS), at least one physical broadcasting channel (PBCH) symbol containing resource elements (REs) mapped for at least one demodulation reference signal (DMRS) sequence over a downlink channel; and determining DMRS REs included in the at least one PBCH symbol, wherein a synchronization signal (SS) block hypotheses is carried in the at least one DMRS sequence that is mapped into the DMRS REs, and wherein the SS block hypotheses includes at least full or partial SS block indices.
Claims20
A user equipment (UE) in a wireless communication system, the UE comprising:
- a transceiver configured to receive, from a base station (BS) over downlink channels, at least one symbol comprising resource elements (REs) mapped for at least one demodulation reference signal (DMRS) sequence of a physical broadcasting channel (PBCH) and REs mapped for PBCH data;
- and
- a processor operably connected to the transceiver, the processor configured to
- determine REs for the DMRS of the PBCH and REs for the PBCH data included in the at least one symbol, wherein the REs for the DMRS of the PBCH and the REs for the PBCH data are interleaved frequency division multiplexed (IFDM),
- detect a synchronization signal (SS) block hypothesis carried in the at least one DMRS sequence that is mapped into the REs for DMRS of PBCH, wherein the SS block hypothesis includes an SS/PBCH block index, and
- decode a PBCH payload that is mapped into the REs for PBCH data.
A base station (BS) in a wireless communication system, the BS comprising:
- a processor configured to:
- determine resource elements (REs) for at least one demodulation reference signal (DMRS) sequence of a physical broadcasting channel (PBCH) and REs for PBCH data,
- generate a synchronization signal (SS) block hypothesis carried in the at least one DMRS sequence that is mapped into the REs for the DMRS of the PBCH, wherein the first part of the SS block hypothesis includes an SS block index, and
- encode a PBCH payload that is mapped into the REs for the PBCH data, and
- generate the at least one symbol using the REs for the DMRS of the PBCH and the REs for the PBCH data, wherein the REs for the DMRS of the PBCH and the REs for the PBCH data are interleaved frequency division multiplexed (IFDM);
- and
- a transceiver operably connected to the processor, the transceiver configured to transmit, to a user equipment (UE) over downlink channels, the at least one symbol containing the REs mapped for the at least one DMRS sequence and the REs mapped for the PBCH data.
