Group communication method and apparatus

A method used in user equipment (UE), the method comprising:

• receiving information from a base station for a first cell, wherein the information includes:
• a radio network temporary identity (RNTI) used in a scheduling point to multipoint (PTM) transmission of the first cell,
• a temporary multicast group identity (TMGI) indicating a multimedia broadcast multicast service (MBMS) scheduled by the RNTI,
• frequency resource configuration information of the scheduling PTM transmission of the first cell, and
• a service list of a scheduling PTM transmission of a neighboring cell of the first cell;
• and
• receiving data on a resource of the scheduling PTM transmission of the first cell from the base station.

An apparatus configured in a base station for a first cell or being a base station for a first cell, the apparatus comprising:

• one or more processors configured to:
• send information to user equipment (UE) in the first cell, wherein the information includes:
• a radio network temporary identity (RNTI) used in a scheduling point to multipoint (PTM) transmission of the first cell,
• a temporary multicast group identity (TMGI) indicating a multimedia broadcast multicast service (MBMS) scheduled by the RNTI,
• frequency resource configuration information of the scheduling PTM transmission of the first cell, and
• a service list of a scheduling PTM transmission of a neighboring cell of the first cell;
• and
• send data on a resource of the scheduling PTM transmission of the first cell.
