Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first physical broadcast channel (PBCH) communication on a channel. The UE may decode the first PBCH communication as a decoded PBCH payload. The UE may reencode the decoded PBCH payload as a first pilot signal. The UE may receive a first data communication with first data. The UE may correct the channel for the first data based on the first pilot signal. The UE may decode the first data. Numerous other aspects are described.

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: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for scheduling and triggering aperiodic channel state information (A-CSI) reporting on a physical uplink control channel (PUCCH) using a downlink grant. An example method generally includes receiving, from a network entity, a downlink grant including a trigger to transmit an aperiodic channel state information (A-CSI) report on a physical uplink control channel (PUCCH), generating the A-CSI report, and transmitting the A-CSI report on the PUCCH using timing and resources indicated in the downlink grant.

Abstract: A method of wireless communication performed by a user equipment (UE), the method including: operating in a mode in which a first subscriber identity module (SIM) is designated as a default data subscription (DDS) and a second SIM is designated as a non-default data subscription (nDDS), including the first SIM being active and the second SIM being idle; determining positions of uplink symbols and downlink symbols within a slot format of the first SIM; causing a hardware switch of the UE to couple the second SIM to an antenna of the UE during a first symbol that is configured as uplink or flexible; and performing a page decode operation by the second SIM while the second SIM is coupled to the antenna.

Abstract: The apparatus in some aspects may be a wireless device configured to operate a first transceiver in a first connected mode with a first radio access network (RAN) and a second transceiver in a second connected mode with a second RAN. The apparatus may further be configured to transmit a first communication via the first transceiver and obtain, based on a second communication via the second transceiver, an indication of a cancellation of one or more symbols for the first communication via the first transceiver. The apparatus may also be configured to refrain from transmitting, based on the indication, a remaining portion of the first communication via a set of symbols including the one or more symbols.
