    摘要: A technique of performing a handover procedure involves providing a proper timing adjustment indication for the UE performing RACH-less HO. Even though the discussion herein is on IAB scenarios and the idea takes an advantage of IAB nodes being in fixed locations (i.e., not moving in the network), it can be applied to UEs in general. The timing adjustment provided in performing a HO in an IAB network according to the improved techniques involves computing a timing advance (TA) to be used by an IAB node prior to executing HO to an alternative serving node. Such a use of a TA may enable a bypassing of a RACH procedure when accessing a cell.

    摘要: In a first method, a gNB-DU indicates, to a second node, a capability information element for generating information related to Other-System Information (OSI); receives an acknowledge indication from the second node; and generates system information broadcast information to at least one user equipment. In a second method, a gNB-CU receives, from a first node, a capability information element for generating information related to Other-System Information (OSI); and transmits an acknowledge indication to the first node.
