Integrated Access Backhaul (IAB) Nodes with Negative Propagation Delay Indication - A simplified explanation of the abstract
This abstract first appeared for US patent application 18354708 titled 'Integrated Access Backhaul (IAB) Nodes with Negative Propagation Delay Indication
Simplified Explanation
- The patent application describes methods performed by an integrated access backhaul (IAB) node in an IAB network. - The IAB node receives timing offset information from an upstream node in the network, which is related to communications between the IAB node and the upstream node. - The IAB node then transmits a downlink (DL) signal to one or more downstream nodes in the network. - The timing of the DL signal transmission is determined based on the IAB node's DL reception timing of a DL signal received from the upstream node, as well as a second timing value calculated using a function of the received timing offset information. - If the function of the timing offset information is greater than a threshold, the second timing value is used to determine the DL transmission timing. - The patent application also mentions that there are other embodiments of IAB nodes configured to perform these methods.
Original Abstract Submitted
Embodiments include methods performed by an integrated access backhaul (IAB) node configured for operation in an IAB network. Such methods include receiving, from an upstream node in the IAB network, first timing offset information related to communications between the IAB node and the upstream node. Such methods include transmitting a downlink (DL) signal to one or more downstream nodes in the IAB network. The DL signal is transmitted according to a DL transmission timing determined from the following: the IAB node's DL reception timing of a DL signal received from the upstream node; and a second timing value determined based on a first function of the first timing offset information, when the first function of the first timing offset information is greater than a threshold. Other embodiments also include IAB nodes configured to perform such methods.
