Abstract: Certain aspects of the present disclosure generally relate to circuitry and techniques for digital-to-analog conversion. One example system for digital-to-analog conversion generally includes a first digital-to-analog converter (DAC) having an input coupled to an input node of the system and a mixing-mode DAC having an input coupled to an input node of the system. The mixing-mode DAC may include a second DAC and a mixer, an output of the second DAC being coupled to an input of the mixer. The system may also include a combiner, wherein an output of the first DAC is coupled to a first input of the combiner, and wherein an output of the mixer is coupled to a second input of the combiner.

Abstract: An apparatus comprising a transmit path, a plurality of local oscillators and a control unit. The control unit may be configured to: receive an upcoming resource block (RB) allocation; determine whether the upcoming RB allocation is the same as the current RB allocation; in response to determining that the upcoming RB allocation is different than the current RB allocation: select an unused LO of the plurality of LOs; determine whether a number of allocated RBs associated with the upcoming RB allocation is greater than a threshold; and in response to determining that the number of allocated RBs associated with the upcoming RB allocation is not greater than the threshold, tune the selected LO to a frequency corresponding to the upcoming RB allocation.

Abstract: Methods, systems, and devices for wireless communication are described. In some systems, a user equipment (UE) may transmit, to a network entity, a first signal including a request to update a resolution of a phase shifting operation associated with beam-based communications. The UE may receive, from the network entity, a second signal approving the request. The UE may communicate using a beam according to an updated resolution of the phase shifting operation based on the second signal approving the request. Additionally, or alternatively, the UE may transmit a first signal including a request to suspend a beam refinement process based on the resolution of the phase shifting operation. The UE may receive a second signal approving the request to suspend the beam refinement process. The UE may communicate with the network entity using a beam based on suspending further beam refinement in response to the second signal.

Abstract: Methods, systems, and devices for wireless communications are described. A communications device may transmit, to a second communications, a request to update a phase shifter configuration. The first communications device may receive, from the second communications device and in response to the request, a response accepting the request to update the phase shifter configuration. The first communications device may then transmit, to the second communications device, an uplink transmission in accordance with the updated phase shifter configuration based on receiving the response. The first communications device may include a first user equipment (UE) and the second communications device may include a second UE or a base station.
