    Abstract: Techniques are described herein for periodically transmitting a first set of signals (e.g., reference signals) during an on-period of a discontinuous reception (DRX) cycle rather than during an off-period of the DRX cycle. Such techniques may enable a user equipment (UE) operating in a DRX mode to conserve additional power during the DRX cycle. A periodicity for transmitting the first set of signals during the on-period may be determined. The periodicity may indicate that every one-in-N DRX cycles, the first set of signals are to be transmitted during the on-period. During other DRX cycles, the first set of signals may be transmitted during the off-period. When the first set of signals are transmitted during the on-period, the UE may refrain from activating certain components during the off-period, thereby conserving power.

    Abstract: Methods, systems, and devices for wireless communications are described that provide for the management of different operation modes in wireless systems. For example, wireless device(s) may operate in a high pathloss operation mode or a normal pathloss operation mode based on the pathloss experienced between the transmitting and receiving devices. In some cases, a first wireless device may transmit a message to a second wireless device to configure a bandwidth part (BWP) for high pathloss mode communications. The message may be transmitted via control signaling and after receipt of the message, the second wireless device may enter a high pathloss mode for communications with the first wireless device (e.g., after a given time duration). Some parameters may be configurable (e.g., transmission duration, coding scheme) between high pathloss mode and normal pathloss mode, while other parameters may remain the same (e.g., processing time, switching time).

    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may transmit a first message indicating a capability to linearize a digital signal outputted by an analog front end of the UE, the digital signal being associated with a first transmission. The UE may receive the first transmission, the first transmission being associated with a gain state comprising a set of configurations associated with a plurality of amplifiers at the UE, and the UE may linearize the digital signal associated with the first transmission based at least in part on the gain state, where linearizing the digital signal comprises obtaining an output voltage value corresponding to an input voltage value associated with the analog front end. In some examples, the UE may obtain an output voltage value from a lookup table (LUT) of a set of LUTs configured to the UE or generated by the UE.

    Abstract: Methods, systems, and devices for wireless communications are described. To reduce peak-to-average power ratio (PAPR) associated with transmissions in a wireless communications system, a user equipment (UE) may implement tone reservation techniques. The UE may receive downlink control information from a base station that indicates a set of allocated resources that the UE is to use for the tone reservation. The UE may identify a first set of tones of the set of allocated resources for transmitting a data signal and a second set of tones of the set of allocated resources for transmitting a peak-reduction signal that reduces the peak power of the data signal. The UE may transmit the data signal and the peak-reduction signal based on the received downlink control information.

    Abstract: This disclosure provides systems, methods, and devices for wireless communication that support power headroom differential reporting for reference resource signals transmitted at different transmission power than other uplink transmissions. In a first aspect, a method of wireless communication includes determining a power headroom value, by a user equipment (UE), using a maximum configured transmission power and a transmission power configured for an uplink transmission at a configured modulation and coding scheme (MCS). The UE determines a reference resource signal power headroom value using the maximum configured transmission power and a reference resource signal transmission power configured for a reference resource signal transmission, calculates a reference resource power headroom differential between the power headroom value and the reference resource signal power headroom value, and transmits a report including the uplink transmission power headroom value and the reference resource power headroom differential. Other aspects and features are also claimed and described.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may generate a signal for a set of synchronization signal blocks (SSBs) for an SSB burst set, wherein the set of SSBs are associated with a set of analog beamforming configurations associated with a set of spatial directions. The base station may transmit the signal for the set of SSBs using the set of analog beamforming configurations over the set of spatial directions. The base station may receive one or more random access channel (RACH) communications corresponding to one or more SSBs of the set of SSBs in accordance with one or more frequency domain beam sweeping configurations corresponding to one or more analog beamforming configurations of the set of analog beamforming configurations. Numerous other aspects are described.
