Abstract: Aspects relate to measurement and event reporting from a distributed unit (DU) of a disaggregated base station to a central unit (CU) of the disaggregated base station. The CU can configure the DU with a measurement configuration associated with at least one value to be obtained by the DU and a reporting configuration for reporting the at least one value to the CU. The measurement reports can be sent by DU periodically or the measurement reports can be event-triggered based on the reporting configuration. In addition, the measurement reports can be UE-specific or DU/cell-specific. The measurement reports may include random access channel (RACH) reports, uplink measurement reports, radio link protocol (RLC) reports, medium access control (MAC) protocol reports, and other types of measurement or event-based reports.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may receive one or more service data units (SDUs) at a layer two (L2) layer of the transmitting device. The transmitting device may encode, at the L2 layer, the one or more SDUs according to one or more network coding parameters to obtain at least one encoded protocol data unit (PDU), the one or more network coding parameters comprising a rateless code. The transmitting device may generate, for the at least one encoded PDU, at least one corresponding PDU header. The transmitting device may output the at least one encoded PDU and the at least one corresponding PDU header from the L2 layer to a lower layer of the transmitting device for transmission to one or more receiving devices.

Abstract: A central unit (CU) transmits synchronization timing information for a multicast broadcast service (MBS) single frequency network (SFN) data transmission in a synchronous manner to multiple distributed units (DUs). The CU transmits the MBS SFN data transmission to the multiple DUs for synchronous transmission to one or more user equipments (UEs). A DU receives synchronization timing information for a MBS SFN data transmission in a synchronous manner with at least one additional DU. The DU transmits the MBS SFN data transmission with a timing based on the synchronization timing information.

Abstract: Aspects present herein relate to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. The apparatus may receive, from a base station, a logged measurement configuration including a PLMN ID and a NID, the logged measurement configuration further including at least one of a trace reference, a logging area, a MDT PLMN list, or a MDT NPN list. The apparatus may also store the PLMN ID and the NID based on the received logged measurement configuration. Additionally, the apparatus may compare the PLMN ID and the NID to an MDT SNPN list to identify if the PLMN ID and the NID are included in the MDT SNPN list. The apparatus may also transmit, to the base station, an availability indicator if the PLMN ID and the NID are included in the MDT SNPN list.

Abstract: Methods (1500, 1600, 1700, 1800, 1900), systems (1000, 1400) and devices (705, 805, 1005, 1105, 1205, 1405) for wireless communications are presented. A method (1500, 1600) may include the following operations. A UE determines to perform a handover from a first source device in a first network to a first target device in the first network and from a second source device in a second network to a second target device in the second network (1505, 1605). The UE identifies a time interval for performing a first random access procedure with the first target device in the first network (1510, 1610). The UE initiates a first random access procedure with the first target device (1515, 1615). The UE performs a second random access procedure successfully with the second target device in the second network during the time interval (1520, 1620). The UE transmits or receives from the target device in the second network before the UE finishes performing the first random access procedure with the first target device in the first network (1525, 1630).
