Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus determines a location of a reference subframe based on an A-CSI report uplink subframe, an A-CSI request downlink subframe, a reference delay, and a report delay. In an aspect, the reference delay is a first delay value before the A-CSI report uplink subframe, and the report delay is a second delay value between the A-CSI request downlink subframe and the A-CSI report uplink subframe. The apparatus determines a type of the reference subframe based on the location of the reference subframe and a subframe configuration, the type of the reference subframe being a flexible subframe or a fixed subframe. The apparatus measures at least one of a channel or interference based on the reference subframe and the type of the reference subframe. The apparatus sends, at the A-CSI report uplink subframe, an A-CSI report based on the at least one of the channel or the interference.

Abstract: Methods, systems, and devices for wireless communication are described. In some wireless systems, a user equipment (UE) may access a network or cell using a random access (RACH) procedure. A base station may allocate dedicated RACH resources and common RACH resources for the UE to transmit a RACH preamble message on and may convey a configuration for the UE. In some cases, the UE may perform multiple transmissions of the RACH preamble message in the dedicated RACH resources, and based on the configuration may determine whether to perform a single or multiple transmissions of the RACH preamble message in the common RACH resources. The UE may transmit the messages using the same or different uplink transmit beams, and the base station may receive the messages using the same or different uplink reception beams. These multiple transmissions may reduce latency and improve reliability of the RACH procedure.

Abstract: Methods, systems, and devices for wireless communications are described. A first base station may identify that the first base station is a secondary node for a user equipment (UE) operating in a dual connectivity deployment, where the UE is in a radio resource control (RRC) inactive state. The first base station may receive, from the UE, a request to resume communications with the first base station and a second base station that is a master node in the dual connectivity deployment. The first base station may verify the UE using an access stratum context associated with the UE, and resume communications with the UE based at least in part on the request and the access stratum context. The first base station may resume communications as a secondary node or as a master node. In some cases, the UE may resume communications without entering an RRC idle state.

Abstract: Generally, the described techniques provide for efficiently identifying a lower layer configuration for communicating in a dual connectivity mode after transitioning from an inactive state to a connected state. To efficiently identify the lower layer configuration, a UE operating in a dual connectivity mode may perform measurements on signals received from a master node, a secondary node, and other nearby nodes in an inactive state. Once the UE decides to transition back to a connected state, the UE may report the measurements and restore an original lower layer configuration used to communicate in a dual connectivity mode. The UE may then receive an indication of an updated lower layer configuration as an offset of the original lower layer configuration, where the updated lower layer configuration may be based on the reported measurements.

Abstract: Certain aspects of the present disclosure provide techniques for an on-demand measurement gap for inter-frequency radio resource management (RRM) measurements. A method for wireless communications by a base station (BS) includes configuring a user equipment (UE) in the serving cell for measurement of target cell (s) and with an on-demand measurement gap configuration for measuring the target cell (s). Neighbor cells in a same frequency can coordinate to align synchronization signal block (SSB) or channel state information reference signal (CSI-RS) transmission and provide timing information of the aligned SSB or CSI-RS transmission to a cell in a different frequency. A method by a UE includes receiving an on-demand measurement gap configuration from a serving cell co and measuring target cell (s) based on the measurement gap configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (HE) may support beam management to determine beams for communicating with a base station, measure characteristics of the beams, and periodically report the measurements to the base station. The beam management may include a beam failure recovery procedure, where the UE detects and resolves a beam failure with the base station. Additionally, the UE may perform radio link monitoring (RLM) on a set of reference signals configured by the base station to determine if a radio link (e.g, beamformed transmission) is synchronized or not between the UE and base station. In some cases, these RLM reference signals (RLM-RSs) may be reconfigured, where the reconfiguration may be based on the periodic beam measurement reports for beam management, a beam monitoring event trigger, a beam failure recovery, or a combination thereof.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently performing measurements and other functions in preparation for communicating with a base station on a secondary cell (SCell). In particular, a user equipment (UE) may switch to a certain bandwidth part (BWP) (e.g., a dormant BWP) on an SCell when the SCell is deactivated, and the UE may perform the appropriate measurements and functions on this BWP (e.g., based on reference signals received on this BWP). In some cases, the UE may determine to switch to the BWP for performing the appropriate measurements and functions based on an inactivity timer expiring or based on an indication from a base station (e.g., on a primary cell (PCell)). Accordingly, once the UE activates the SCell for communications with a base station, the latency associated with preparing for communicating on the SCell may be reduced.

Abstract: Systems, apparatuses, and methods for configurations for small data transmission by which a user equipment transmits, to a base station, user data within a random access message in a radio resource control inactive state. The user equipment may receive, via broadcast system information and/or unicast messages from the base station, a configuration on support capability or parameters for small data transmission. Based on the received configuration, the user equipment may transmit user data to the base station. The user equipment may transmit a random access preamble on a resource separately reserved for small data transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, information that configures multiple random access channel (RACH) partitions, wherein the multiple RACH partitions are each associated with a respective combination of one or more RACH features. The UE may select, from the multiple RACH partitions, a RACH partition based at least in part on the UE satisfying one or more criteria for the combination of one or more RACH features associated with the RACH partition. The UE may transmit, to the base station, a preamble on physical RACH (PRACH) resources associated with the RACH partition to initiate a RACH procedure supporting the combination of one or more RACH features associated with the RACH partition. Numerous other aspects are described.
