Abstract: Aspects of the present disclosure provide techniques that may be utilized by a UE for performing neighbor cell measurement and reselection in narrowband deployment scenarios, such as NB-IoT deployment scenarios. For example, a method for wireless communications by a user equipment (UE), can include determining, while communicating in a serving cell, information regarding one or more transmission deployment mode parameters of at least one neighbor cell, and performing a neighbor cell search with measurement of narrowband reference signals (NRS) based on the one or more transmission deployment mode parameters.

Abstract: Aspects presented herein relate to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. The apparatus may receive, from a base station, an indication of at least one of an update to one or more PC parameters, an update to an UL beam indication, or an update to the one or more PC parameters associated with the UL beam indication. The apparatus may also configure, based on the indication, a PC adjustment state for an active UL BWP of a CC. The apparatus may also transmit, to the base station, an uplink channel or an uplink signal based on the configured PC adjustment state for the active UL BWP of the CC.

Abstract: Cell reselection and other operations involving signal measurements at a UE may increase the power consumption and operation complexity at a UE, such as a reduced capacity UE (RedCap UE). In some scenarios, for example, a UE may need to frequently switch to bandwidth parts (BWPs) outside the bandwidth of its initial DL bandwidth part to receive and measure synchronization signal blocks (SSBs) for cell reselection, which increases the power consumption of the UE. The aspects described herein allow a UE to measure SSBs in one or more bandwidth parts that is not an initial DL bandwidth part configured by a serving cell of the UE in response to an event trigger or a message received at the UE. The SSBs may be associated with the serving cell of the UE or with a non-serving cell. The UE performs a cell reselection operation based on the measurements.

Abstract: This disclosure provides systems, methods and apparatuses for enabling downlink throttling, such as for thermal mitigation. For example, a user equipment (UE) may transmit channel state feedback (CSF) with a report of a first rank that is less than a second rank associated with a channel condition and may communicate with a base station using a configuration associated with the first rank and without a set of sounding reference signals (SRSs). Alternatively, the UE may transmit one or more SRSs using a configuration associated with the first rank. In this way, by refraining from transmission of the SRSs or by adjusting the configuration the SRSs, the UE causes the base station to support downlink throttling.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communication by a user equipment (UE). According to certain aspects, a UE may be configured to detect, in a first bandwidth part (BWP), a condition triggering a mobility procedure that involves a physical random access channel (PRACH) transmission in a second BWP, determining a timeline for transmitting the PRACH in the second BWP, based on a mobility procedure delay that accounts for BWP switching time for switching from the first BWP to the second BWP, and transmitting the PRACH in the second BWP in accordance with the timeline.

Abstract: In order to enable a UE receiving a narrowband signal transmitted using in-band resources to use the LTE reference signals to assist the UE in receiving the narrowband signal using an in-band deployment, a phase rotation employed by the base station may be fixed relative to a known reference position in time. An apparatus for wireless communication at a base station may determine a phase offset for a narrowband signal for transmission using wideband resources, the phase offset having a relationship to a reference point in time and transmit the narrowband signal using the determined phase offset. An apparatus for wireless communication at a UE may receive a narrowband signal having a frequency location within a wideband signal and rotate a symbol of the wideband signal by a per symbol phase offset having a relationship of the phase offset to a reference point in time.
