Abstract: Aspects include systems and methods for compressed direct current (DC) location reporting, such as DC location reporting in uplink (UL) carrier aggregation (CA) deployments in a wireless network. Various aspects may include a UE computing device determining and indicating DC locations only for a subset of a plurality of component carriers (CCs) in a channel bandwidth to a base station and/or a UE computing device determining and indicating DC locations for a subset of activation permutations for bandwidth parts (BWPs) of a plurality of CCs in a channel bandwidth that is less than all possible activation permutations of the BWPs of the plurality of CCs in the channel bandwidth.

Abstract: Aspects of the present disclosure provide techniques for managing unwanted transmissions by a wireless communications device, such as spurious transient transmissions caused by changing a power level of a transmitter. An exemplary method includes determining, based on one or more parameters, an action to reduce an impact of a spurious transmission by the UE, wherein the spurious transmission relates to at least one of changing a transmit power level at the UE or switching one or more radio components at the UE, and taking the determined action to reduce the impact.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine an emissions mask (e.g., an in-band emission (IBE) mask) for a user equipment (UE) which may be determined based on the total number of UEs scheduled by the base station for uplink transmissions during a same transmission time interval (TTI). The base station may transmit downlink control information (DCI) to the UE indicating the emissions mask. The base station may additionally transmit a grant to the UE allocating resources for the UE based on the UE's position relative to other UEs served by the base station. The UE may receive the DCI and may map the emissions mask to a maximum power reduction (MPR). Based on the MPR, the UE may determine a transmit power and may transmit an uplink transmission to the base station according to the transmission power and the DCI.

Abstract: Methods, systems, and devices for enhanced carrier aggregation techniques described. For example, component carrier groups including multiple component carriers may be configured. In some cases, each component carrier group may be configured to include 2n component carriers. Also, component carriers may be managed on a per component carrier group basis. In some cases, a single management message may be used to communicate management information for a component carrier group. Similarly, a single control message may be used to communicate control information, such as physical layer parameters, for a component carrier group.

Abstract: Low complexity, high order multiple input, multiple output (MIMO) operations are described in which a user equipment (UE), configured with at least one normal performance receiver chain and at least one low-performance, low-complexity diversity receiver chain, signals a capabilities indicator identifying existence of the low-performance diversity receivers. Using the UEs capabilities, a serving base station may schedule uplink and downlink transmissions for the UE to reduce uplink-downlink collisions below a minimum threshold number. The serving base station may also take UE transmit power into consideration for signaling power control or modulation and coding schemes in order to minimize potential interference cause by UE transmissions. For channel state feedback, the UE may provide different channel feedback for uplink-downlink collision subframes and non-collision subframes.

Abstract: A user equipment (UE) can report direct current (DC) subcarrier location information for a subset of possible combinations of bandwidth parts and component carriers supported by a base station. In one aspect, the UE can receive, from a scheduling entity, a message for activating a first combination of bandwidth parts (BWPs) and component carriers (CCs) in a list including a subset of combinations of BWPs and CCs configured for the UE. The UE can report direct current subcarrier location information for the first combination of BWPs and CCs to the scheduling entity.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a UE capability message, the UE capability message indicating a supported transmit antenna switching (TxAS) capability for each port of the UE. The UE may receive a configuration message indicating an uplink multiple-input/multiple-output (UL MIMO) configuration for the UE, the UL MIMO configuration being based at least in part on the UE capability message. The UE may identify, based at least in part on the configuration message, a sounding reference signal (SRS) configuration to use for transmitting SRSs in conjunction with the UL MIMO communications, the SRS configuration comprising a configuration for transmission by the UE of SRSs using at least one of the two or more ports of the UE, the SRSs transmitted on one or more antennas of the UE selected according to a TxAS configuration for the respective port.

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.
