Abstract
Methods, systems, apparatus for implementation in an integrated access and backhaul network (IAB) are described. One example method for wireless communication includes transmitting, by a first network node connected to one or more second network nodes by one or more first wireless links, a system information message on a second wireless link, the system information message indicating all public land mobile networks to which the one or more second network nodes provide connectivity.
Claims12
A method for wireless communication, comprising:
- receiving, by a first network node over a wireless link from a parent node of the first network node, system information including identifications (IDs) of public land mobile networks (PLMNs) supported by central units (CUs) that are connected to the parent node;
- transmitting, by the first network node over the wireless link to a second network node, a first message indicating that the first network node supports the PLMNs;
- and
- requesting, by the first network node, an internet protocol (IP) address on a per-public land mobile network basis from the second network node, the requesting informing the second network node a requested number of IP addresses, a version of the IP address, and a usage of the IP address, and
- wherein the first network node is an integrated access and backhaul mobile termination (IAB-MT) node, the second network node is a central unit (CU), and the first message includes the IDs of the PLMNs,
- wherein the IP address requested by the first network node corresponds to one of the PLMNs supported by the first network node such that a packet containing a traffic belonging to a corresponding PLMN is encapsulated with the IP address, and
- wherein PLMNs supported by the second network node cover the PLMNs supported by the first network node.
4 more elements
An apparatus for wireless communication comprising at least one processor configured to:
- receive, from a parent node of the apparatus over a wireless link, system information including identifications (IDs) of public land mobile networks (PLMNs) supported by central units (CUs) that are connected to the parent node;
- transmit to a second network node over the wireless link, a first message indicating that the apparatus is capable of a radio access network sharing feature, wherein the apparatus is an integrated access and backhaul mobile termination (IAB-MT) node and wherein the second network node is a central unit (CU);
- and
- request an internet protocol (IP) address on a per-public land mobile network basis from the second network node, the requesting informing the second network node a requested number of IP addresses, a version of the IP address, and a usage of the IP address,
- wherein the at least one processor causes the apparatus to operate as an integrated access and backhaul mobile termination (IAB-MT) node, the second network node is a central unit (CU), and the first message includes the IDs of the PLMNs,
- wherein the IP address requested by the apparatus corresponds to one of the PLMNs supported by the apparatus such that a packet containing a traffic belonging to a corresponding PLMN is encapsulated with the IP address, and
- wherein PLMNs supported by the second network node cover the PLMNs supported by the apparatus.
4 more elements
A non-transitory computer-readable medium having code stored thereupon, the code, upon execution by at least one processor, causing the at least one processor to operate as a first network node and implement a method comprising:
- receiving, from a parent node of the first network node over a wireless link, system information including identifications (IDs) of public land mobile networks (PLMNs) supported by central units (CUs) that are connected to the parent node;
- transmitting, to a second network node over the wireless link, a first message indicating that the first network node is capable of a radio access network sharing feature, wherein the first network node is an integrated access and backhaul mobile termination (IAB-MT) node and wherein the second network node is a central unit (CU);
- and
- requesting an internet protocol (IP) address on a per-public land mobile network basis from the second network node, the requesting informing the second network node a requested number of IP addresses, a version of the IP address, and a usage of the IP address,
- wherein the first network node is an integrated access and backhaul mobile termination (IAB-MT) node, the second network node is a central unit (CU), and the first message includes the IDs of the PLMNs,
- wherein the IP address requested by the first network node corresponds to one of the PLMNs supported by the first network node such that a packet containing a traffic belonging to a corresponding PLMN is encapsulated with the IP address, and
- wherein PLMNs supported by the second network node cover the PLMNs supported by the first network node.
