Abstract: Wireless communication devices are adapted to utilize maximum permissible exposure requirements in determining uplink traffic grant allocations within wireless communication systems. According to one example, a wireless communication device can determine one or more candidate uplink duty cycles for a subsequent uplink transmission interval based at least in part on an MPE requirement, determine a maximum number of resource blocks per symbol and a maximum MSC index associated with each of the one or more candidate uplink duty cycles from a predefined MCS index table, and select a duty cycle, number of resource blocks per symbol, and MCS that facilitates a largest number of un-coded bits for the subsequent uplink transmission interval. Other aspects, embodiments, and features are also included.

Abstract: Methods and systems for determining transmission power levels according to signal types and RF exposure limits. An example method generally includes determining a first transmission power for transmitting a first type of uplink (UL) signal, determining a second transmission power for transmitting a second type of UL signal based on the first transmission power, and transmitting at least one of the first UL signal according to the first transmission power or the second UL signal according to the second transmission power.

Abstract: Certain aspects of the present disclosure relate to beam selection. An example method generally includes selecting, from a plurality of beams, a beam for uplink transmission during a particular time interval, the selecting being based on a transmission power and a radio frequency (RF) exposure for each of the plurality of beams and transmitting at least one uplink signal using the selected beam during the particular time interval.

Abstract: Certain aspects of the present disclosure provide a method for wireless communication by a base station (BS). The method generally includes receiving an indication of current remaining available transmit power from a user equipment (UE). The method further includes communicating information indicating a data rate parameter and a communication configuration to the UE. The data rate parameter is for use by the UE on an uplink with the BS. The communication configuration affects uplink transmission duty cycle on the uplink based on whether the current remaining available transmit power and a current channel state between the BS and the UE satisfy a condition. The method further includes receiving signals based on the data rate parameter and the communication configuration from the UE on the uplink.

Abstract: Aspects of the disclosure relate to a method of operating a scheduled entity for wireless communication with a network. In some aspects, the scheduled entity transmits a message that requests a scheduling entity to transmit at least one reference signal. The scheduled entity obtains channel state information based on the at least one reference signal. The scheduled entity transmits a report that includes the channel state information. In other aspects, the scheduled entity transmits a message that requests a scheduling entity to schedule a reference signal transmission for the scheduled entity. The scheduled entity obtains an assignment of resources for transmission of the reference signal in response to the message. The scheduled entity transmits the reference signal based on the assignment of resources. Other aspects, embodiments, and features are also claimed and described.

Abstract: Aspects of the present disclosure relate to receiver beamforming for serving and neighbor cell measurements. An exemplary method generally includes communicating with one or more base stations using a first beam type, initiating a transition to communicating with at least one of the one or more base stations using a second beam type in response to an indication of a trigger event, and communicating with the at least one of the one or more base stations using the second beam type.

Abstract: A method, an apparatus, and a computer-readable medium may be described in the present disclosure. The apparatus may be a user equipment. The apparatus may determine whether a number of unsuccessful repetitions associated with performance of a first type of scanning exceeds a repetition threshold. The apparatus may perform a second type of beam scanning based on the determination that the number of unsuccessful repetitions exceeded the repetition threshold.
