Abstract: Methods, systems, and devices for wireless communications are described. According to one or more aspects, a device, such as a user equipment (UE), may establish a primary cell (PCell) connection and a secondary cell (SCell) connection which may trigger a power headroom (PHR) report and initiate a timer for PHR reporting based on the triggering. The UE may configure a bandwidth part (BWP) associated with the SCell connection to operate in a first dormancy state. The UE may receive an indication to configure the SCell BWP to operate in a second dormancy state and may switch the SCell BWP operations to the second dormancy state. The UE ay determine a status of the timer for PHR reporting and may determine whether to transmit a PHR report based on the status of the timer and the indication to switch the BWP operations.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive synchronization signal block (SSB) related measurement configurations exclusively in a system information block (SIB). The UE may receive SSB frequency lists for idle measurements in both a SIB or a radio resource control (RRC) message, such as an RRC release message. In some examples, the UE may receive SSB related measurement configurations or SSB frequency lists for idle measurements in a SIB and an RRC message. Additionally or alternatively, the UE may receive SSB frequency lists in a SIB and an RRC message, while SSB measurement configurations for SSB frequencies out of a sync raster may exclusively be indicated in the RRC message. The UE may therefore experience improved coverage and reliability and, in some examples, may promote low latency for wireless communications relating to multiple radio access technologies, among other benefits.

Abstract: This disclosure provides systems, methods, apparatus, computer programs encoded on computer readable-medium to provide a user equipment (UE) to receive reference signals from a first base station, perform radio resource management (RRM) measurements based on the reference signals, and transmit information regarding the RRM measurements to a second base station. In another aspect, a UE receives reference signals from a first base station, performs channel quality indicator (CQI) measurements based on the reference signals, stores information regarding the CQI measurements, and transmitting the stored information to the first base station. In another aspect, a base station receives, from a UE, information associated with CQI measurements related to a second base station, and transmits the information to the second base station.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine to operate as a relay UE based on a set of thresholds configured for the first UE. The UE may transmit a relay discovery announcement on a communication channel of a sidelink to indicate support for relay communications. A remote UE may monitor for and receive the relay discovery announcement on the sidelink communications channel. The remote UE may select the relay UE based on a set of criteria for selecting a candidate relay UE. The remote UE and the relay UE may establish the relay communications based on the relay discovery announcement transmitted on the communications channel of the relay sidelink.

Abstract: This disclosure provides systems, methods and apparatus for aperiodic measurement configurations. In one aspect, delaying transitioning of a secondary cell group (SCG) to an active state until a next synchronization signal block (SSB) or periodic reference signal may result in an excessive delay in obtaining network resources of the SCG. Some aspects described herein enable a base station (BS) to transmit signaling using a master cell group (MCG) cell to schedule resources for an aperiodic reference signal transmission and measurement using the SCG. For example, the BS may transmit signaling to a user equipment (UE) to identify a reference signal resource for an aperiodic reference signal transmission and measurement. In this case, the BS may transmit the aperiodic reference signal using an SCG cell, and the UE may measure the aperiodic reference signal and provide a report identifying the measurement of the aperiodic reference signal.

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 (BS), a paging communication while the UE is in an inactive mode or an idle mode. The UE may transmit, to the BS and based at least in part on receiving the paging communication, a first communication as part of a random access channel (RACH) procedure. The UE may receive, from the BS and based at least in part on transmitting the first communication, a second communication that includes mobile-terminated downlink data, an indication of an uplink resource, and a radio resource control (RRC) release message. The RRC release message may cause the UE to remain in the inactive mode or the idle mode while receiving the mobile-terminated downlink data. The UE may transmit mobile-originated uplink data using the uplink resource. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently transmitting data and control information in a first RACH message to a base station as part of a two-step RACH procedure. In particular, rather than or in addition to transmitting data and control information in a physical uplink shared channel (PUSCH) in the first RACH message, a user equipment (UE) may transmit the data and control information along with a RACH preamble in a RACH occasion in the first RACH message (e.g., when the number of bytes of data or control information to be transmitted is low). Using these techniques, in some instances, the UE may transmit the data and control information in a first RACH message without transmitting the PUSCH, and the overhead associated with transmitting the PUSCH may be eliminated.

Abstract: Certain aspects of the present disclosure provide techniques performing measurement reporting. One aspect is a method for performing measurement reporting at a user equipment, including: receiving, from a master node, a message comprising a measurement configuration for a secondary node; entering an inactive state; performing measurements according to the measurement configuration for the secondary node immediately after entering the inactive state; generating a measurement report based on the measurements; transmitting, to the master node, an RRC resume request message; receiving, from the master node, an RRC resume message comprising a request for measurement reporting; and transmitting, to the master node, an RRC resume complete message comprising the measurement report; and receiving data from the secondary node.

Abstract: Certain aspects of the present disclosure generally relate to methods and apparatus for performing minimization of drive test (MDT) operations. For example, certain aspects provide a method for wireless communication. The method generally includes receiving, at a radio access network (RAN), a measurement configuration to start a trace of a user-equipment (UE), determining a transition of the UE to an inactive state, and sending one or more messages to coordinate the trace of the UE or indicate that the trace has failed in response to the determination.
