Reduced capability non-terrestrial idle mode signaling

A non-terrestrial radio network node, comprising at least one processor configured to process executable instructions that, when executed by the at least one processor, facilitate performance of operations, comprising:

• determining content to be broadcast via a reduced-content synchronization signal block signal message;
• and
• broadcasting, via an idle-mode beam, the reduced-content synchronization signal block signal message comprising at least one first idle-mode beam preamble indication of at least one first idle-mode beam preamble of a first idle-mode beam preamble group and at least one second idle-mode beam preamble indication indicative of at least one second idle-mode beam preamble of a second idle-mode beam preamble group and comprising at least one idle-mode beam uplink resource indication indicative of at least one idle-mode beam uplink resource usable by the non-terrestrial radio network node to receive from at least one user equipment at least one of the at least one first idle-mode beam preamble or at least one of the at least one second idle-mode beam preamble, wherein at least one of the at least one first idle-mode beam preamble or the at least one second idle-mode beam preamble is to be usable by the at least one user equipment to establish a connection with the non-terrestrial radio network node, and wherein the non-terrestrial radio network node avoids including, in the reduced-content synchronization signal block signal message, master information block information corresponding to the non-terrestrial radio network node.

A non-transitory machine-readable medium, comprising executable instructions that, when executed by at least one processor of a non-terrestrial radio network node, facilitate performance of operations, comprising:

• receiving a network energy saving configuration message comprising at least one network energy saving mode criterion;
• determining that the at least one energy saving mode criterion is satisfied;
• based on the at least one energy saving mode criterion being determined to be satisfied, broadcasting, via an idle-mode beam, a reduced-content synchronization signal block signal message comprising at least one first idle-mode beam preamble, at least one second idle-mode beam preamble, and an idle-mode beam uplink resource indication indicative of at least one idle-mode beam uplink resource usable by the non-terrestrial radio network node to receive from at least one user equipment at least one of the at least one first idle-mode beam preamble or the at least one second idle-mode beam preamble, wherein the at least one first idle-mode beam preamble or the at least one second idle-mode beam preamble is to be usable by the at least one user equipment to facilitate establishing a connection with the non-terrestrial radio network node, and wherein the non-terrestrial radio network node avoids inclusion, in the reduced-content synchronization signal block signal message, of minimum system information.
