Abstract: Techniques for determining power relaxation values are disclosed. The power relaxation values may be determined according to an ending resource block (RB) and a number of RBs in a contiguous allocation. In one aspect, the power relaxation values are arranged into regions based, at least in part, on transmission channel bandwidths and the distance from a protected adjacent channel. A user equipment (UE) can determine a power relaxation value for its current allocation using the ending RB index and contiguous RB length and can adjust its transmission power accordingly. Evolved NodeBs may estimate the power relaxation that a particular UE has selected in order to more accurately determine the transmit power available to the UE. Using the more accurate estimate of transmit power, the eNB may schedule the UE for uplink transmissions accordingly.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a plurality regulation requirement parameters corresponding to an unlicensed carrier, where the unlicensed carrier spans at least a portion of a first unlicensed band associated with a first set of regulation requirements and at least a portion of a second unlicensed band associated with a second set of regulation requirements. The UE may identify, from the plurality of regulation requirement parameters, a set of regulation requirement parameters for an uplink transmission based at least in part on whether a set of frequency resources for the uplink transmission overlaps with the first unlicensed band and the second unlicensed band. The UE may transmit the uplink transmission using the set of regulation requirement parameters.

Abstract: Methods, systems, and devices for wireless communications are described in which a base station may signal one or more emission limits for one or more different frequency bands, and two or more values for one of the emission limits may be provided. A first subset of user equipments (UEs) may be capable of aerial operations (e.g., unmanned aerial vehicles (UAVs) or drones) and may use a first value of the first emission limit and the second subset of UEs may not capable of aerial operations and may use a second value of the first emission limit. A UE status such as altitude or position, or transmission directivity may also be used to determine if the UE is to apply the first value or the second value for an emission limit of a frequency band.

Abstract: A method, computer-readable medium, and apparatus operate to reduce or eliminate interference with one or more other communication systems having specific transmission requirements within a specific geographic area. For example, aspects operate by determining that a user equipment (UE) is in a protection zone where additional transmission requirements apply. The additional transmission requirements enable coexistence with one or more other communication systems in the protection zone. The UE may identify, based on being in the protection zone and a coexistence mode, one or more transmit emission limit requirements to be met. The UE may identify, based on being in the protection zone and the coexistence mode, one or more maximum transmit power requirements to be met. The UE may configure a transmit output power, at which the UE can meet the one or more transmit emission limit requirements and the one or more maximum transmit power requirements.

Abstract: To support very high QAM rates, a user equipment (UE) needs extremely good signal-to-noise ratio (SNR). Using a receiver configuration that improves SNR comes at the expense of higher power consumption. However, consuming higher power to support very high QAM rates when poor channel conditions are present is a waste of power. By correlating the modulation and coding scheme used by the UE with the UE channel quality estimate, the UE can modify the receiver configuration to improve SNR only when channel conditions support very high QAM rates.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine that uplink communications are to be performed between the UE and a first cell group associated with a first radio access technology (RAT) and between the UE and a second cell group associated with a second RAT. The UE may determine that the UE is configured for power sharing for the uplink communications with the first cell group associated with the first RAT and the second cell group associated with the second RAT. The UE may calculate, based on the power sharing and the uplink communications, a power reduction factor for the uplink communications between the UE and the second cell group. The UE may perform the uplink communications with the first cell group and selectively perform the uplink communications with the second cell group.
