Abstract: Apparatuses and methods include determining a first initial random access channel (RACH) preamble power based on one or more of a history of RACH preamble powers, a history of common pilot channel (CPICH) chip energy to total power density ratio (EcIo) measurements, and a history of CPICH received signal code power (RSCP) measurements, wherein each of the history of RACH preamble powers, the history of CPICH EcIo measurements, and the history of CPICH RSCP measurements corresponds to previous RACH procedures when the RACH procedure succeeded, and initiating subsequent RACH procedures with preambles that are based on the first initial RACH preamble power. Some present aspects may reduce the push to talk (PTT) call setup latency.

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: Disclosed are systems and methods for controlling by the User Equipment (UE) downlink power in early decode termination mode. In one aspect, the UE may be configured to perform early decoding of a downlink (DL) transmission from a base station. The UE further configured to estimate a signal-to-interference ratio (SIRE) of the DL transmission. Based on the SIRE, the UE is configured to select a Transmission Power Control (TPC) command sequence for a low power mode of operation of the UE in which a receiver is powered down. The UE is further configured to activate the low power mode and transmit the selected TPC command sequence to the base station to adjust a DL transmission power during the low power mode.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether a slot timing difference, between a first cell and a second cell for a dual connectivity mode, satisfies a threshold value, where the first cell is a serving cell associated with a first radio access technology (RAT) and the second cell is a serving cell or a candidate cell associated with a second RAT. The UE may perform an operation to prevent the dual connectivity mode with the second cell, establish the dual connectivity mode with the second cell, maintain the dual connectivity mode with the second cell, or terminate the dual connectivity mode with the second cell based at least in part on whether the slot timing difference satisfies the threshold value. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for protecting shared low noise amplifiers by limiting transmission power. A method that may be performed by a user equipment (UE) includes determining that a transmission by the UE on a frequency band via a first radio access technology (RAT) overlaps in time with a period that the UE is configured to receive on the frequency band via a second RAT; and limiting transmission power on the first RAT during the period.

Abstract: The present disclosure describes a method and an apparatus for pruning false peaks during slot synchronization at a user equipment (UE). For example, a method is provided to identify a plurality of first peaks associated with a primary-synchronization channel (P-SCH) received at the UE and a plurality of second peaks from the plurality of first peaks. Further, one or more pruning locations along with associated energy thresholds for each of the plurality of the second peaks may be determined and whether a peak of the plurality of the first peaks is a false peak is identified based on whether the peak is located at one of the one or more pruning locations of the peak and an associated energy value of the peak does not satisfy the associated energy threshold of the pruning location. Furthermore, the peak identified as the false peak is discarded.
