System information adaptation for non-terrestrial networks
This patent document describes, among other things, techniques, and apparatuses for providing non-terrestrial network connectivity to improve wireless network efficiency and performance. In one aspect, a method of wireless communication is disclosed. The method includes transmitting, from a network node to a user device, a block of system information that includes system information that is time varying due to at least one of movement of the network node or movement of the user device.
1 . A method of wireless communication, comprising:
transmitting, from a network node to a user device, a block of system information that includes system information that is time varying due to movement of the network node;
wherein the block of system information comprises a system information block (SIB);
wherein the SIB is updated over time according to:
a predefined period based on an orbit height range, or a predefined period based on a speed range of the network node.
2 . The method of claim 1 , wherein the system information includes a position-velocity-time (PVT) information indicative a position of the network node, a velocity of the network node and a time at the network node.
3 . The method of claim 1 , wherein the system information includes a scheduling delay value.
4 . The method of claim 1 , wherein the system information includes a timing advance value.
5 . The method of claim 1 , wherein the system information includes a timing drift value.
6 . The method of wireless communication of claim 1 , wherein the system information block is updated over time aperiodically with a corresponding indication in a short message with a bit indication.
7 . A network node, comprising one or more processors configured cause the network node to:
transmit, to a user device, a block of system information that includes system information that is time varying due to movement of the network node;
wherein the block of system information comprises a system information block (SIB);
wherein the SIB is updated over time according to:
a predefined period based on an orbit height range, or a predefined period based on a speed range of the network node.
8 . The network node of claim 7 , wherein the system information includes a position-velocity-time (PVT) information indicative a position of the network node, a velocity of the network node and a time at the network node.
9 . The network node of claim 7 , wherein the system information includes a scheduling delay value.
10 . The network node of claim 7 , wherein the system information includes a timing advance value.
11 . The network node of claim 7 , wherein the system information includes a timing drift value.
12 . The network node of claim 7 , wherein the system information block is updated over time aperiodically with a corresponding indication in a short message with a bit indication.
