Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may apply a per chain transmit power split to a cumulative maximum transmit power level (MTPL). The UE may calculate a value associated with a conditional power backoff, wherein the value associated with the conditional power backoff is calculated after the per chain transmit power split is applied to the cumulative MTPL. The UE may transmit, using multiple transmit chains, an uplink signal using a final transmit power level, wherein the final transmit power level is based on a value of the cumulative MTPL after the per chain transmit power split is applied to the cumulative MTPL and the calculated value associated with the conditional power backoff. Numerous other aspects are described.

Abstract: Systems are disclosed for a communication system optimized for low data volume communications. In embodiments of the invention, the energy used to transmit an acknowledgement message differs depending on whether the acknowledgement is an ACK or a NACK. The energy used to transmit an ACK is set to be significantly less than the energy used to transmit a NACK. Preferably, the energy used to transmit the acknowledgement message is negligible if the acknowledgement message is an ACK compared to if the acknowledgement message is a NACK. In one embodiment, the energy used to transmit an ACK is set near zero and the energy used to transmit a NACK is set approximately four times the energy of an acknowledgement message if the energy required to transmit a NACK and an ACK were equal.

Abstract: An access point (AP) communicates to one or more stations (STAs) information indicating a set of channels and/or resource units (RUs), corresponding to a wideband basis service set (BSS) for an authorized unlicensed radio local area network (RLAN) using 6 GHz spectrum, which are subject to a lower power spectral density (PSD) level than other portions of the BSS frequency range or are not to be used for transmission. In some, but not necessarily all, embodiments, the AP and the STAs do not encode data on the identified channels or RUs, but do encode data on other channels and/or other RUs, which are not subject to the lower PDS constraint.
