Abstract: A parent node in a wireless communication network is arranged to communicate backhaul traffic wirelessly with an Integrated Access Backhaul (IAB) node. The parent node may determine time resources for a distributed unit (DU) of the IAB node to communicate backhaul traffic with a child node or a mobile terminal, and transmit an indication of the determined time resources to the IAB node. The parent node may also determine time resources for a mobile termination (MT) of the IAB node to communicate backhaul traffic with the parent node, and transmit an indication of the determined time resources to the IAB node. The IAB may receive, from the parent node, at least one indication of time resources for communicating backhaul data with the parent node, and communicate backhaul data with the parent node based on the time resources. The IAB node may also receive, from the parent node, at least one indication of time resources for communicating backhaul data with the child node or the mobile terminal, and communicate backhaul data with the child node or the mobile terminal based on the time resources.

Abstract: A method and an apparatus for transmitting and receiving Time Division Duplex (TDD) frame configuration information are disclosed. The base station transmits TDD frame configuration information as system information to a user equipment through a common control channel so as to dynamically change the TDD frame configuration according to uplink and downlink traffic conditions. The base station may deliver the same system information to all user equipments in the cell, removing ambiguity in User Equipment (UE) operations and avoiding interference. In comparison to an existing method of delivering TDD frame configuration information through system information update, the disclosed method enables user equipments to rapidly cope with traffic changes. In addition, user equipments may receive and apply TDD frame configuration information at the same time.
