Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may operate in a dual-connectivity (DC) configuration, and may measure signals from more than one radio access technology (RAT). The UE may receive a first signal power for a first RAT and a second signal power for a second RAT. The UE may determine a common gain state for the first RAT and the second RAT based on the first signal power and the second signal power. The UE may then apply the common gain state to a first receiver chain within the UE for the first RAT and to a second receiver chain within the UE for the second RAT, where the first receiver chain and the second receiver chain share at least one shared low noise amplifier (LNA).

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment may identify a frequency drift condition that affects user equipment (UE) performance and may operate in modes of operation to optimize UE performance under frequency drift conditions. For example, the UE may estimate the rate of change of frequency error at the modem based on pilot signals, and if the change exceeds a threshold, the UE may enter into a frequency error response configuration to optimize performance under the high frequency error condition. The frequency error response configuration may involve an adjustment to channel state information feedback, an adjustment to a periodicity of synchronization signal block (SSB) or tracking reference signal (TRS) monitoring, use of an updated set of parameters for demodulation reference signal (DMRS) channel estimation, or use of an updated set of parameters for frequency tracking.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may determine, based at least in part on two or more measurements on a channel taken at different points in time, that the channel is classified as static. The wireless communication device may perform at least one optimization based at least in part on determining that the channel is classified as static. For example, the at least one optimization may include modifying a channel state feedback procedure, reducing a periodicity associated with a measurement gap, modifying a filtering associated with measurements of the channel, reducing a threshold associated with beam switching, and/or refraining from performing at least one filtering at a radio frequency receiver of the wireless communication device. 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 measure a first energy level of a demodulation reference signal (DMRS). The UE may measure a second energy level of at least one of a tracking reference signal (TRS) or a synchronization signal block (SSB). The UE may determine, based at least in part on the first energy level and the second energy level, a DMRS signal-to-noise ratio (SNR). The UE may perform, based at least in part on the DMRS SNR, channel estimation for a physical channel associated with a communication to determine an estimated channel. The UE may perform, based at least in part on the estimated channel, demodulation processing for the communication. 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 select a maximum supported rank for reception that is capped based at least in part on one or more impacted antennas of the UE that are unavailable due to sounding reference signal (SRS) switching that switched at least one antenna of the UE. The UE may transmit an indication of the maximum supported rank. The UE may receive a selected rank that is no greater than the maximum supported rank. The UE may receive, from one or more non-impacted antennas of the UE, a communication using the selected rank. Numerous other aspects are described, such as downlink blanking, desensing parameters, canceling SRS switching, and uplink blanking for impacted antennas.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may communicate via a first component carrier (CC) during a first time period. The UE may communicate via a second CC during a second time period. The UE may receive a first indication to deactivate the second CC during a third time period that at least partially overlaps with the first time period. The UE may receive a second indication to activate the second CC for communication during a fourth time period. The UE may communicate via the second component carrier during the fourth time period using an initial frequency error correction at a beginning of the fourth time period, the initial frequency error correction based at least in part on a frequency error of the first CC during the third time period. 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 determine an actual power delay profile (PDP) associated with a channel between the UE and a base station, wherein the actual PDP indicates an averaged power level of the channel over a period of time. The UE may determine whether a channel estimation mode switching event is satisfied. The UE may switch, based at least in part on the channel estimation mode switching event being satisfied, between a first channel estimation mode based at least in part on the actual PDP and a second channel estimation mode based at least in part on a template PDP. Numerous other aspects are described.

Abstract: Aspects of the disclosure relate to a user equipment (UE) configured to schedule resource management procedures including measurements and tracking loop procedures. In some examples, the UE includes at least one antenna pair and two or more receivers. The UE may be configured to determine a plurality of combinations of antenna pairs and component carriers, where each component carrier is associated with a particular frequency. The UE may further be configured to schedule measurements/tracking loop procedures to available receivers first and utilize a selection algorithm to select combinations of antenna pairs and component carriers and map the selected combinations to the remaining of the available receivers to perform tracking loop procedures. Other aspects, features, and embodiments are also claimed and described.
