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.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may establish, with a network entity, a wireless connection that uses a set of symbols per transmission time interval (TTI) for orthogonal frequency division multiplexing (OFDM) communications, where each symbol of the set of symbols may correspond to a fast Fourier transform (FFT) window and may include a guard interval (GI) portion and a data portion within the FFT window. In some examples, the UE may receive a control message indicating at least one parameter associated with a power offset between a data signal of the set of symbols and a reference signal of the set of symbols that is associated with the data signal. As such, the UE may communicate with the network entity, the data signal, and the reference signal according to the indicated power offset using the set of symbols.

Abstract: Wireless communication devices, systems, and methods related to downlink control information (DCI) designs for multi-component carrier scheduling are provided. For example, a method of wireless communication can include receiving a downlink control information (DCI) message having a DCI format, the DCI message scheduling a downlink data communication over a single component carrier or multiple component carriers; determining, based on the received DCI message, whether the downlink data communication is scheduled over the single component carrier or the multiple component carriers; and receiving, based on the determining, the downlink data communication over the single component carrier or the multiple component carriers.

Abstract: Methods, systems, and devices for wireless communications are described. For a set of scheduled transmission instances of a data communication, a transmitting network node may determine a first spatial filter to apply for a first subset of the scheduled transmission instances configured to provide the data communication and a second spatial filter to apply for a second subset of the scheduled transmission instances configured to allow energy harvesting at an energy harvesting device. In some cases, the transmitting network node may indicate a first quasi co-location (QCL) relation to use for the first subset of the scheduled transmission instances configured to provide the data communication to the network node receiving the data transmissions, and the transmitting network node may indicate a second QCL relation to use for the second subset of the scheduled transmission instances configured to allow energy harvesting to the energy harvesting device.
