Abstract: Embodiments methods implemented with a server or a processor of a mobile communication device (e.g., a multi-standby communication device) reduce the redundancy information needed to achieve adequate reception service on a first radio access technology (RAT) sharing an RF resource with a second RAT. The device processor may implement at least one tune-away management strategy that mitigates the amount of data for the first RAT that is lost during the tune-away event. Thus, by implementing the one or more tune-away management strategies, the device processor may ensure that less redundancy information overhead is needed to correct or replace lost or partially received data, improving latency, channel usage, and the first RAT's overall reception performance. In some embodiments, a server may implement one or more strategies for including redundancy information into data that is sent to a first RAT to mitigate the negative effects of tune aways on the first RAT.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which a user equipment performs an inter-radio access technology (RAT) mobility procedure from a first network to a second network while idle mode signaling reduction (ISR) is active, locally deactivates ISR in connection with completion of the inter-RAT mobility procedure, and initiates a location management procedure in the second network. Depending on the respective type of the first and second network, and the connection state of the UE with respect to the first network, the mobility procedure may be performed in response to a mobility command received from the first network, or in response to a mobility condition of the first network as detected by the UE.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which user equipment performs a circuit-switched fallback procedure to connect to a CDMA2000 network. The CDMA2000 network may be selected by the UE or by the network. A plurality of PLMN IDs may be maintained, where the IDs relate to a network that includes an LTE RAN. Each PLMN ID may be associated with a CDMA2000 network sharing the LTE RAN. A CDMA2000 network may be selected for circuit-switched fallback of a user equipment operating in the LTE RAN. The user equipment may be configured to perform a circuit-switched fallback procedure on the selected CDMA2000 network. The CDMA2000 network may be selected by a mobility management entity responsive to a PLMN selection procedure. The PLMN selection procedure may be performed when the UE reports multiple-operator capability.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may transmit assistance information indicating a type of in-device coexistence (IDC) interference at the UE, and indicating a set of associated interference parameters that correspond to an interference pattern of the IDC interference in a time domain, a frequency domain, or both. The set of interference parameters and the interference pattern may describe a pattern of the IDC interference in the time domain, the frequency domain, or both. The UE may receive a message indicating one or more operating parameters associated with a time period that is based on the interference pattern. The operating parameters may be based on the type of IDC, the set of interference parameters, and the interference pattern, and may enable the UE to communicate with a network entity to maintain signaling throughput while decreasing effects of the IDC interference.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a primary cell or a primary secondary cell (PSCell), configuration information for a conditional PSCell addition or change (CPAC), the configuration information indicating configurations for one or more candidate PSCells. The UE may detect a failure, associated with the conditional PSCell addition or change, associated with a first target PSCell from the one or more candidate PSCells. The UE may perform an action to recover the CPAC based at least in part on detecting the failure. Numerous other aspects are described.

Abstract: The disclosure relates to methods, devices, and systems for wireless communications. In some wireless communications systems, a base station may transmit a multicast message to a group of user equipment (UEs), and the UEs may provide feedback for the multicast message. In some implementations, the base station may configure the UEs to transmit feedback for multicast messages. In some example, the UEs may transmit group-negative acknowledgment (NACK) feedback information for multicast messages that are not successfully received at the UEs. In some other examples, each UE may be configured with UE-specific uplink control channel resources for transmitting hybrid automatic repeat request (HARQ) feedback for a multicast message. In some implementations, a UE may support feedback for both unicast and multicast messages. The semi-static codebook for unicast, multicast, or both may account for whether the UE is capable of concurrently receiving unicast and multicast messages in a slot.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node may transmit, to a second wireless node, a cross-link interference (CLI) management configuration message including a permutation indicator, wherein the permutation indicator indicates that an order of slot formats is an uplink-flexible-downlink order of slot formats or indicates that the order of slot formats is a downlink-flexible-uplink order of slot formats; and communicate with one or more third wireless nodes in accordance with the order of slot formats indicated to the second wireless node. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may directly send small data to a disaggregated base station without performing a random access procedure. The CU-CP may provide a list of routing identifiers and corresponding data resource bearers (DRBs) to a distributed unit (DU) and the DU may transmit a connection release message to the UE. The connection release message may include the list of routing identifiers and the list of DRB identifiers. The connection release message may also include a downlink monitoring timer. The UE may identify data for an uplink transmission and a DRB associated with that data. The UE may transmit a packet with the data and the routing identifiers to a DU, which may derive downlink address information from the routing identifiers and forward the data to a CU-UP of the aggregated base station.

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.
