Abstract: Methods and apparatuses relate to sounding reference signal (SRS) transmit antenna selection in wireless communication systems. For example, a user equipment (UE) may select, from a set of antennas, a subset of antennas for SRS transmission based on at least one antenna selection parameter. The UE may further transmit, on an uplink communication channel, the SRS using the subset of antennas to a network entity. In some aspects, the at least one antenna selection parameter may include a reference signal receive power (RSRP) value, a signal-to-noise ratio (SNR) value, a spectrum efficiency value, and/or an SNR value and a channel correlation value.

Abstract: Techniques for providing transmission throttling for emission exposure management are described. Embodiments implement duty cycle based transmission throttling for emission exposure management. Transmission throttling implemented in accordance with embodiments drops or skips transmission of some portion of transmission blocks of a communication process, such as to drop some transmission blocks providing retransmission of data. Transmit power levels utilized with respect to each of transmission blocks transmitted may be closer to that of a transmit power control target level (e.g., meeting the TPC target level) while nevertheless meeting an emission exposure limit level. Embodiments may, for example, be implemented with respect to a hybrid automatic repeat request (HARQ) process. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications at a user equipment (UE) are described. Aspects of the described techniques may include the user equipment measuring signal aspects for a plurality of respective receive beams for receiving communications associated with a synchronization signal block transmitted by a base station on a transmit beam. From the measured signal aspects, the UE may determine that a receive beam from the plurality of receive beams is a preferred beam for receipt of communications from the base station transmitted on the transmit beam. With the determined preferred beam, the UE may initiate a beam-sweeping procedure to re-measure the plurality of UE receive beams, where the UE measures the first UE receive beam before measuring others of the plurality of UE receive beams.
