Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a distributed unit (DU) of a network node may receive, from one or more of a user equipment (UE), a central unit (CU) of the network node, or another network node, assistance information, wherein the assistance information indicates one or more of: robust header compression (ROHC) feedback information, uplink data related information, packet reordering timer information, congestion related information, session control information, or radio resource control (RRC) message information. The DU may perform an action associated with the UE based at least in part on the assistance information. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive cell characteristic information of multiple network nodes associated with different network architectures. The UE may select a network node, from the multiple network nodes, based at least in part on a mapping rule and the cell characteristic information, wherein the mapping rule is associated with UE information and cell or network information. The UE may transmit a random access channel (RACH) message to establish a connection with the network node. Numerous other aspects are described.

Abstract: This disclosure provides methods, components, devices and systems for enhanced downlink and uplink scheduling based on assistance information related to PDCP status reports. Some aspects specifically relate to a wireless communication system including a disaggregated base station architecture in which a CU provides a DU assistance information related to PDCP status reports from which assistance information the DU may determine appropriate downlink or uplink scheduling start timing for a UE. In some examples, the DU obtains from the CU assistance information indicating an unreceived PDCP SDU at a UE or the CU, and sends downlink data or an uplink grant to the UE based on the assistance information. The CU may deliver the downlink data to the DU prior to sending the assistance information or obtain uplink data from the DU after sending the assistance information. Duplication of PDCP SDU transmissions and unnecessarily extended scheduling delays may thus be minimized.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive a control message indicating one or more parameters associated with selecting one or more cells. The UE may select one or more first cells to monitor for a paging message based on the one or more parameters and may monitor the one or more first cells for the paging message in an idle mode, inactive mode, or any non-connected mode based on the selection. Additionally, the UE may select one of the one or more first cells or a second cell to establish a connection based on monitoring for the paging message and may establish the connection with the one of the one or more first cells or the second cell based on the selection.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may establish a network interface link with a centralized unit (CU). The network node may establish a set of one or more network interface links with a set of one or more distributed units (DUs). The network node may receive a first communication intended for a destination node via the network interface link. The network node may transmit the first communication to a first DU of the set of one or more DUs via a first network interface link of the set of one or more network interface links. The network node may receive a second communication intended for the destination node via the network interface link. The network node may transmit, after transmitting the first communication via the first network interface link, the second communication to a second DU via a second network interface link. Numerous other aspects are described.
