Abstract: Certain aspects of the present disclosure provide techniques and apparats relating to designs for the remaining minimum system information (RMSI) control resource set (CORESET) and the other system information (OSI) CORESET. In certain aspects, a wireless communication device (e.g., user equipment) is enabled to determine the location of Type0-PDCCH common search space CORESET and the OSI CORESET in the frequency and time domains based on the location of the synchronization signal block (SSB) transmissions in the frequency and time domains. Determining the location of the RMSI CORESET and the OSI CORESET frequency and time resources enables the UE to receive the RMSI CORESET and the OSI CORESET, respectively.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a UE capability message indicating support for a dual-base station control resource allocation scheme during a make-before-break (MBB) handover procedure, the dual-base station control resource allocation scheme comprises dividing a maximum number of UE supported control channel monitoring resources between a source base station and a target base station. The UE may identify, based at least in part on the dual-base station control resource allocation scheme, a first set of control channel monitoring resources for the source base station and a second set of control channel monitoring resources for the target base station. The UE may receive, during the MBB handover procedure, control information from the source base station during the first set of control channel monitoring resources and from the target base station during the second set of control channel monitoring resources.

Abstract: Techniques are described herein for mobility procedures configured to maintain connectivity with a device, such as a user equipment (UE), when the UE moves between single-frequency network (SFN) areas. When the UE operates in a radio resource control (RRC) inactive state or an RRC idle state, the UE may utilize hierarchical mobility. As the UE moves throughout the coverage area of the network, the UE may use mobility procedures for moving between a serving radio access network (RAN) notification area (RNA) and a neighboring RNA (e.g., inter-RNA procedures), and/or procedures for moving between SFN areas within the serving RNA (e.g., intra-RNA procedures), which may include procedures for moving between tracking areas (TAs). In some mobility procedures, the UE may skip decoding a system information block. In some mobility procedures, the UE may skip reading the system information. An SFN area may be a radio access network area code (RAN-AC).

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may operate in a radio resource control (RRC) inactive state of a discontinuous reception (DRX) mode. The UE may identify, based at least in part on the UE operating in the RRC inactive state, a single frequency network (SFN) for a notification zone that is configured for the UE, the notification zone comprising a plurality of cells. The UE may receive one or more synchronization signal blocks (SSBs) broadcast by the plurality of cells over the SFN. The UE may perform a channel measurement procedure based at least in part on the one or more SSBs received over the SFN.

Abstract: Methods, systems, and devices for wireless communications are described. A device may receive signaling including a channel state information (CSI) reporting configuration. The device may determine one or more resources of a physical uplink channel for aperiodic CSI reporting based on the CSI reporting configuration and transmit an aperiodic CSI report over the physical uplink channel based on the on the one or more resources. In some examples, the device may also determine a set of demodulation reference signal (DMRS) symbols associated with a hop of a set of hops in a time domain or a frequency domain, and coherently transmit, based on the determining, the set of DMRS symbols associated with the hop of the set of hops.

Abstract: Methods, systems, and devices for wireless communications are described for service continuity in make-before-break handover procedures. A user equipment (UE) may receive grants for two or more concurrent communications with a source base station and a target base station during the handover procedure, where the UE may be incapable of performing the two or more concurrent communications. The UE may use one or more priority rules to determine communication priority. The one or more priority rules identify one or more channel types that have a higher priority than other channel types, may identify whether communications with the source base station or the target base station have priority, among other examples.

Abstract: Generally, the described techniques provide for duplex mode configuration for control information (e.g., duplex mode configuration for communication of downlink control information). For example, duplex modes may be defined (e.g., as full duplex (FD) capable, FD only, half duplex (HD) only, etc.), and such duplex modes may be configured for control resource sets (CORESETs), search space (SS) sets, or both. In some examples, duplex modes configured for a CORESET/SS set may depend on the priority of information conveyed via the CORESET/SS set. For example, a CORESET/SS set for high priority or critical control information may be configured with a HD mode to avoid FD self-interference, while CORESET/SS set for other control information may be configured with a FD mode to improve spectrum efficiency. Techniques for resolving conflicting duplex mode configurations (e.g., when a HD mode is configured for a SS set within a CORESET configured with FD) are also described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first synchronization signal (SS) block that does not include remaining minimum system information (RMSI). The first SS block may indicate an offset for obtaining a second SS block that includes RMSI. The UE may determine a location of the second SS block based at least in part on the offset. Numerous other aspects are provided.

Abstract: Techniques are described herein for signaling procedures that use a hierarchical mobility, which may be applied when a user equipment (UE) is operating in a radio resource control (RRC) inactive state or the RRC idle state. A wireless communication system may be configured with a plurality of areas in which one or more networks are established for communicating certain types of signals. Examples of the areas associated with networks may include a tracking area (TA), a radio access network area code (RAN-AC), a radio access network based notification area (RNA). A synchronization signal or a paging signal may be transmitted using a first set of communication resources in a first area, while the synchronization signal or the paging signal may be transmitted using a second set of communication resources in a second area different than the first set of communication resources.
