Protection of control signaling in a wireless backhaul network

An apparatus for wireless communication at a first parent node of a wireless backhaul network, comprising:

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive, from a donor node of the wireless backhaul network, a token associated with a reselection procedure for a child node of the wireless backhaul network, the token being unique to a first wireless link between the first parent node and the child node and associated with a procedure to determine whether to perform the reselection procedure;
• determine that a triggering event has occurred after receiving the token, the triggering event associated with a link between the first parent node and the donor node;
• and
• transmit, in response to determining that the triggering event has occurred, the token to the child node over the first wireless link to trigger the procedure to determine whether to perform the reselection procedure at the child node to select a new parent node of the wireless backhaul network based at least in part on a verification of the token.

An apparatus for wireless communication at a first parent node of a wireless backhaul network, comprising:

• means for receiving, from a donor node of the wireless backhaul network, a token associated with a reselection procedure for a child node of the wireless backhaul network, the token being unique to a first wireless link between the first parent node and the child node and associated with a procedure to determine whether to perform the reselection procedure;
• means for determining that a triggering event has occurred after receiving the token, the triggering event associated with a link between the first parent node and the donor node;
• and
• means for transmitting, in response to determining that the triggering event has occurred, the token to the child node over the first wireless link to trigger the procedure to determine whether to perform the reselection procedure at the child node to select a new parent node of the wireless backhaul network based at least in part on a verification of the token.

A non-transitory computer-readable medium storing code for wireless communication at a first parent node of a wireless backhaul network, the code comprising instructions executable by a processor to:

• receive, from a donor node of the wireless backhaul network, a token associated with a reselection procedure for a child node of the wireless backhaul network, the token being unique to a first wireless link between the first parent node and the child node and associated with a procedure to determine whether to perform the reselection procedure;
• determine that a triggering event has occurred after receiving the token, the triggering event associated with a link between the first parent node and the donor node;
• and
• transmit, in response to determining that the triggering event has occurred, the token to the child node over the first wireless link to trigger the procedure to determine whether to perform the reselection procedure at the child node to select a new parent node of the wireless backhaul network based at least in part on a verification of the token.
