SUPPORT OF SC-PTM BASED MULTICASTING FOR BL/CE AND NB-IoT UEs

A baseband apparatus for User Equipment (UE), comprising:

• an interface to radio frequency (RF) circuitry;
• and
• one or more processors to:
• monitor a common search space (CSS) of a Machine-Type Communications (MTC) Physical Downlink Control Channel (MPDCCH) or Narrowband Physical Data Control Channel (NPDCCH) for the scheduling of a Physical Downlink Shared Channel (PDSCH) or a Narrowband Physical Downlink Shared Channel (NPDSCH), respectively, wherein the monitoring of the CSS includes:
• decoding a single downlink control information (DCI) transmission, wherein a cyclic redundancy check (CRC) portion of the DCI transmission is scrambled using a Single-Cell Radio Network Temporary Identifier (SC-RNTI) that includes scheduling information for a Single-Cell Multicast Control Channel (SC-MCCH) and wherein indications of changes in the SC-MCCH configuration are carried via one or more bits of the DCI;
• and
• receive, via the interface to RF circuitry and based on the decoded first and second DCI transmissions, the SC-MCCH.

A User Equipment (UE) apparatus comprising:

• a computer-readable medium containing processing instructions;
• and
• one or more processors, to execute the processing instructions to:
• transmit, to a Single-Cell Point-To-Multipoint (SC-PTM) base station, multicast service preference information, including at least one of a Coverage Enhancement (CE) mode or a maximum Transport Block Size (TBS) of the UE;
• and
• monitor a common search space (CSS) of a MTC Physical Downlink Control Channel (MPDCCH) or Narrowband Physical Data Control Channel (NPDCCH) for the scheduling of a Physical Downlink Shared Channel (PDSCH) or a Narrowband Physical Downlink Shared Channel (NPDSCH), respectively, to obtain downlink control information (DCI) that includes configuration information relating to a Single-Cell Multicast Control Channel (SC-MCCH);
• and
• receive, based on the DCI, the SC-MCCH.

A computer-readable medium containing program instructions for causing one or more processors, of User Equipment (UE), to:

• monitor a common search space (CSS) of a Machine-Type Communications (MTC) Physical Downlink Control Channel (MPDCCH) or Narrowband Physical Data Control Channel (NPDCCH) for the scheduling of a Physical Downlink Shared Channel (PDSCH) or a Narrowband Physical Downlink Shared Channel (NPDSCH), respectively, wherein the monitoring of the CSS includes:
• decoding a single downlink control information (DCI) transmission, wherein a cyclic redundancy check (CRC) portion of the DCI transmission is scrambled using a Single-Cell Radio Network Temporary Identifier (SC-RNTI) that includes scheduling information for a Single-Cell Multicast Control Channel (SC-MCCH) and wherein indications of changes in the SC-MCCH configuration are carried via one or more bits of the DCI;
• and
• receive, based on the decoded first and second DCI transmissions, the SC-MCCH.
