Abstract: Disclosed are systems and techniques for wireless communications. For instance, a wireless device may receive a signal from a first wireless network while the wireless device is in an idle mode; determine, from the received signal, a signal to noise ratio (SNR) and a doppler shift; retrieve stored network capability information; and estimate, based on the SNR, the doppler shift, and the stored network capability information, a throughput of the first wireless network.

Abstract: Methods, systems, and devices for wireless communication are described. In some systems, a user equipment (UE) may divide a measurement of a cell into two or more portions. The UE may receive a control message that indicates a request to perform the measurement and a target frequency associated with the measurement. In some examples, the UE may generate at least a first radio frequency (RF) script during an on duration of a discontinuous reception (DRX) cycle based on the target frequency. The UE may perform at least a portion of the measurement during an off duration of the DRX cycle based on the first RF script. Additionally or alternatively, the UE may generate the first RF script and perform the portion of the measurement during an off duration of a DRX cycle and the UE may generate a second RF script during an off duration of a second DRX cycle.

Abstract: Aspects described herein relate to communicating with multiple cells based on two separate subscriptions stored at the UE in a dual subscription dual standby (DSDS) mode, switching to communicate with the multiple cells in a dual subscription dual active (DSDA) mode, transmitting, to at least one of the multiple cells and based on a number of component carriers allowed for a subscription being exceeded by switching to communicate in the DSDA mode, assistance information to indicate a threshold amount of component carriers for the UE, and transmitting, to at least one of the multiple cells and based on the number of component carriers allowed for the subscription being exceeded by switching to communicate in the DSDA mode, a channel quality indicator (CQI) value for one or more cells of the multiple cells to request deactivation of one or more component carriers with, or release of, the one or more cells.

Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish a first call associated with a first subscriber of the UE. The UE may establish a second call associated with a second subscriber of the UE, wherein the first subscriber and the second subscriber are active contemporaneously, and wherein the first call and the second call are associated with a first radio access technology (RAT). The UE may identify a mobility event that associated with an interruption to at least one of the first call and the second call, the mobility event involving switching the first subscriber to a second RAT. The UE may perform a mitigation action. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include the user equipment (UE) selecting, based at least in part on an operating characteristic for the UE, a procedure for entering a sleep mode from among a set of procedures for entering the sleep mode. The set of procedure may include a first procedure and a second procedure. Upon selecting the procedure, the UE may monitor for page signaling for the UE during a time period and perform the selected procedure for entering the sleep mode.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be configured to transmit sounding reference signals (SRSs) on a first carrier over multiple symbols within a slot, the first carrier being different from a second carrier on which the UE communicates with a base station during the slot. For example, the base station may transmit, to the UE, an SRS configuration for the UE to transmit the SRSs. In accordance with the control message, the UE may tune to the first carrier and may transmit the SRSs over the multiple symbols within the slot on the first carrier before tuning back to the second carrier. In some examples, the UE may transmit a capability message to the base station indicating that the UE supports transmitting SRSs over multiple symbols within a slot before tuning back to a different carrier.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for improving voice over new radio (VoNR)-to-voice over long term evolution (VoLTE). An example method generally includes communicating with and camping on a next generation node B (gNB) in a 5G new radio (NR) system; initiating a voice call with the gNB; receiving a 5G NR-to-long term evolution (LTE) handover command in response to initiating the voice call; performing a handover procedure in response to the handover command; detecting a failure in the handover procedure; and taking one or more actions in response to detecting the failure in the handover procedure.

Abstract: Aspects relate to a UE adapting the capability it advertises based on the network within which the UE is operating. In some examples, if a network currently supports a certain bandwidth, the UE may select the capabilities it will advertise based on that supported bandwidth. In some examples, a UE may acquire information regarding which configurations were considered by a network. In this case, the UE may select the capabilities it will advertise based on such configurations.

Abstract: A method of wireless communication performed at a user equipment (UE), includes transmitting, to a network node, a first indication of a first UE radio capability, the first UE radio capability indicating support for a group of evolved universal terrestrial radio access network (E-UTRAN) new radio (NR) dual connectivity (EN-DC) band combinations. The method also includes receiving, from the network node, an indication of an active EN-DC band combination based on transmitting the first indication. The method further includes transmitting, to the network node, a second indication of a second UE radio capability based on an actual data throughput metric associated with the active EN-DC band combination satisfying a failure condition. The second UE radio capability may indicate support for one or more non-active EN-DC combinations. Each non-active EN-DC combination may be associated with a potential data throughput metric that is greater than a data throughput threshold value.
