Abstract
The present disclosure introduces a method implemented at a user equipment. The method includes: determining, within a physical downlink control channel, one or more bits of a downlink control information that indicates a corresponding physical downlink shared channel carrying a remaining minimum system information or other system information. A user equipment and a corresponding network node are also introduced.
Claims13
A method at a wireless device for communication, the method comprising:
- identifying a physical downlink control channel (PDCCH) according to an obtained control resource set (CORESET) configuration;
- receiving a downlink control information (DCI) message on the identified PDCCH;
- determining, from the received DCI message, a scheduled physical downlink shared channel (PDSCH) on which system information is to be carried;
- receiving the scheduled PDSCH carrying the system information, wherein a system information indicator is enclosed in a PDSCH payload for the system information;
- and
- identifying, from the system information indicator, a type of the system information to be carried on the PDSCH is remaining minimum system information (RMSI) or other system information (OSI).

A method at a network node for communication, the method comprising:
- broadcasting a control resource set (CORESET) configuration in which a physical downlink control channel (PDCCH) is indicated;
- transmitting a downlink control information (DCI) message on the PDCCH, wherein the DCI message comprising scheduling information for a physical downlink shared channel (PDSCH) carrying system information, and one or more bits indicating a type of the system information to be carried on the PDSCH is remaining minimum system information (RMSI) or other system information (OSI);
- transmitting the system information on the scheduled PDSCH, wherein a system information indicator is enclosed in a PDSCH payload for the system information;
- and
- scheduling transport block (TB) size for the system information transmission to be carried on PDSCH, wherein TB size of RMSI is different from TB size of OSI.

A wireless device, comprising:
- an antenna configured for wireless communication;
- a processing circuitry;
- and
- a device readable medium including instructions which, when executed by the processing circuitry, cause the wireless device to:
- identify a physical downlink control channel (PDCCH) according to an obtained control resource set (CORESET) configuration;
- receiving a downlink control information (DCI) message on the identified PDCCH;
- determine, from the received DCI message, a scheduled physical downlink shared channel (PDSCH) on which system information is to be carried;
- receive the scheduled PDSCH carrying the system information, wherein a system information indicator is enclosed in a PDSCH payload for the system information;
- and
- identify, from the system information indicator, a type of the system information to be carried on the PDSCH is remaining minimum system information (RMSI) or other system information (OSI).
7 more elements
A network node, comprising:
- an interface configured for wireless communication;
- a processing circuitry, and
- a device readable medium including instructions which, when executed by the processing circuitry, cause the network node to:
- broadcast a control resource set (CORESET) configuration in which a physical downlink control channel (PDCCH) is indicated;
- transmit a downlink control information (DCI) message on the PDCCH, wherein the DCI message comprising scheduling information for a physical downlink shared channel (PDSCH) carrying system information, and one or more bits indicating a type of the system information to be carried on the PDSCH is remaining minimum system information (RMSI) or other system information (OSI);
- transmit the system information on the scheduled PDSCH, wherein a system information indicator is enclosed in a PDSCH payload for the system information;
- and
- schedule transport block (TB) size for the system information transmission to be carried on PDSCH, wherein TB size of RMSI is different from TB size of OSI.
