Abstract
A base station includes a controller configured to perform a process of transmitting configuration information for a user terminal having a group communication function specified in 3rd Generation Partnership Project (3GPP). The configuration information includes specific subframe information indicating a specific subframe capable of constituting a physical downlink shared channel (PDSCH) for multicast.
Claims12
A base station, comprising:
- a controller configured to perform a process of transmitting an RRC (Radio Resource Control) message including configuration information for a user terminal having an SC-PTM (Single cell point to multipoint) function specified in 3rd Generation Partnership Project (3GPP),
- wherein the configuration information includes specific subframe information indicating a specific subframe capable of constituting a physical downlink shared channel (PDSCH) for multicast, and
- after transmitting the RRC message, the controller is configured to transmit, at the specific subframe, PDCCH (Physical Downlink Control Channel) including resource allocation information of the PDSCH.
A user terminal having an SC-PTM (Single cell point to multipoint) function defined in 3rd Generation Partnership Project (3GPP), comprising:
- a controller configured to perform a process of receiving an RRC (Radio Resource Control) message including configuration information from a base station that manages a serving cell,
- wherein the configuration information includes specific subframe information indicating a specific subframe capable of constituting a physical downlink shared channel (PDSCH) for multicast data to be received by the user terminal, and
- after receiving the RRC message, the controller is configured to receive, at the specific subframe, PDCCH (Physical Downlink Control Channel) including resource allocation information of the PDSCH.
A communication control method, comprising:
- transmitting, by a base station, an RRC (Radio Resource Control) message including configuration information for a specific user terminal having an SC-PTM (Single cell point to multipoint) function specified in 3rd Generation Partnership Project (3GPP),
- wherein the configuration information includes specific subframe information indicating a specific subframe capable of constituting a physical downlink shared channel (PDSCH) for multicast, and
- after transmitting the RRC message, the base station transmits, at the specific subframe, PDCCH (Physical Downlink Control Channel) including resource allocation information of the PDSCH.
