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 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: Aspects are provided which allow a UE to apply CFO compensation to resolve mismatched RAPIDs caused by uplink Doppler shifts in HST deployments. The UE obtains one or more RARs each including a RAPID, where each of the RARs is responsive to a random access message including a preamble. The UE determines, in each of a threshold number of the one or more RARs, that the RAPID of a corresponding RAR is different than the preamble of a corresponding random access message. The UE then offsets a carrier frequency for each of one or more subsequent random access messages in response to the determination. As a result, mismatched RAPIDs due to uplink Doppler shifts may be avoided and RACH success rates may thereby be improved.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. Some aspects more specifically relate to selectively discarding a hybrid automatic repeat request (HARQ) state in association with a HARQ state retention timer or downlink control information (DCI) misdetection information. In some aspects, a user equipment (UE) may discard a HARQ state in association with an expiration of the HARQ state retention timer. Additionally or alternatively, the UE may identify DCI misdetection information that indicates a likelihood that the UE did not receive first DCI transmitted by the network node. The UE may discard the HARQ state in association with the likelihood being greater than a threshold. In some aspects, the UE may receive second DCI that includes an NDI, and may transmit a communication in association with selectively discarding the HARQ state and receiving the DCI.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first sounding reference signal (SRS) configuration, wherein the first SRS configuration indicates a number of antenna ports on which an SRS is to be transmitted. The UE may determine that the number of antenna ports indicated by the first SRS configuration exceeds an antenna capability of the UE. The UE may transmit one or more SRSs using a second SRS configuration based at least in part on determining that the first SRS configuration exceeds the antenna capability of the UE. Numerous other aspects are described.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus determines a first decoding candidate in a first search space and a second decoding candidate in a second search space, where the first decoding candidate and the second decoding candidate have a same size but different definitions of information fields, identifies a difference in the information fields, and determines one of the first decoding candidate and the second decoding candidate as a valid candidate based on the identified difference.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to dynamically updating filtering configuration in modem baseband processing. A method is provided for wireless communications. The method may be performed, for example, by a user equipment (UE). The method generally includes detecting one or more conditions regarding one or more metrics of a received signal and updating, based on the detection, a configuration of one or more filters designed to mitigate an effect of spurious signals associated with (e.g., that fall within) a bandwidth of the received signal.
