Indication of system information update via a downlink shared channel

A method for wireless communication at a second device, comprising:

• establishing a communication link with a group of devices;
• determining a system information update for a first device in the group of devices based at least in part on establishing the communication link;
• transmitting, to the first device based at least in part on determining the system information update, downlink control information in a downlink control channel and a message in a downlink shared channel, the message comprising an indication of a system information update for the first device and one or more updated system information elements that are associated with a cell selection parameter, a cell re-selection parameter, a cell measurement parameter, or any combination thereof;
• and
• communicating with the first device in the group of devices based at least in part on transmitting the downlink control information and the indication of the system information update in the message.

An apparatus for wireless communication at a first device, comprising:

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• establish a communication link with a second device;
• receive, from the second device based at least in part on establishing the communication link, downlink control information in a downlink control channel and a message in a downlink shared channel, the message comprising an indication of a system information update for the first device and one or more updated system information elements that are associated with a cell selection parameter, a cell re-selection parameter, a cell measurement parameter, or any combination thereof;
• determine the system information update for the first device based at least in part on receiving the downlink control information and the indication of the system information update in the message;
• update system information for the first device based at least in part on determining the system information update;
• and
• communicate with the second device based at least in part on updating the system information.
