Abstract: Methods, systems, and devices for wireless communications are described. A mobile integrated access and backhaul (IAB) node may transmit, to an IAB supported network, an indication of IAB capability. The mobile IAB node may also indicate to the IAB supported network a mobility status associated with the mobile IAB node. The IAB supported network may conditionally determine authorization for the mobile IAB node based on the mobility status, a subscription status, or both. The IAB supported network may transmit, to the mobile IAB node, instruction to operate in an IAB mode and perform the IAB operation. The mobile IAB node may communicate with one or more devices based on the instruction.

Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for wireless communication. In one aspect of the disclosure, a method for wireless communication performed by a user equipment (UE) includes receiving, from a base station, mapping information indicating, for each bandwidth part (BWP) of multiple BWPs, a mapping between a respective beam direction of multiple beam directions and the BWP. The method further includes receiving an allocation of a first BWP. The method also includes communicating, via the first BWP, one or more first messages using a first beam having a first beam direction, and receiving, from the base station, a change indicator associated with a second BWP or a second beam direction. The method includes communicating, via the second BWP, one or more second messages using a second beam having a second beam direction. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may initiate handover from one base station to another. The handover procedure may not include random access channel (RACH) transmissions, and thus may be a localized RACH-less handover. The UE may initiate handover to a new base station based on the relative location of the UE and the new base station, some predetermined time, or based on the characteristics of the signals from each base station.

Abstract: Methods, systems, and devices for wireless communications are described. a first donor node may serve a relay node, which in turn may serve a child node. The first donor node may determine to transfer (e.g., via a handover procedure) the relay node to a second donor node. The first donor node may transmit a first context transfer request for the relay node to the second donor node, and may transmit a second context transfer request for the child node of the relay node to the second donor node. The first donor node may indicate a correlation between the two context transfers. The second donor node may identify the correlated context transfers, and may successfully perform a migration procedure for the relay node and any descendent devices or nodes based on the correlated context transfers.

Abstract: Aspects relate to enhancing the provision of gaps at transitions between resources allocated for communication on access links and resources allocated for communication on backhaul links. In some examples, a child integrated access backhaul network (IAB) node may transmit a message to a parent IAB node requesting a number of guard symbols to provide a gap at transitions. In some examples, the parent IAB node may transmit the number of guard symbols provided at transitions to the child IAB node. The parent IAB node, child IAB node, and/or an IAB donor node central unit may further identify a subcarrier spacing associated with the number of guard symbols.
