Claim 6:
7. A method, comprising:
performing, by an integrated access and backhaul (IAB) node or relay node, relaying using a first type of relaying or a second type of relaying, the first type requiring more processing time at the IAB node or the relay node than the second type;
determining the type of relaying for an access user device or child IAB node at least based on one or more of a latency requirement and feedback information on a channel;
scheduling transmissions to or from access user devices or child IAB nodes at least according to a determined type of relaying, wherein transmissions using the first type of relaying are scheduled to take place in the time domain of a transmission slot after transmissions using the second type of relaying; and
transmitting in feedback to a parent node information indicating the scheduling of transmissions to or from the access user device or the child IAB node in the IAB node or the relay node, wherein the information indicating the scheduling of transmissions comprises information on accessing user devices or child IAB nodes according to a preferred order, or information indicating which access to the user devices or the child IAB nodes are requested to be scheduled to a beginning part or an end part of a slot, or information indicating the IAB node's or relay node's capability of supporting a first type and/or a second type of relaying per the access user device or the child IAB node, or information comprising feedback of the access user devices or the child IAB nodes on channel quality, or long term statistic of channel quality and/or long term statistics of success rate of transmissions of the type of relaying used per access user device or child IAB node, or performance and latency experienced in transmissions; and
processing transmissions to or from the access user device or child IAB node according to the determined type of relaying.
