Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, one or more downlink grants scheduling one or more corresponding downlink transmissions from the base station to the UE. In some examples, the UE may enter a state of sleep prior to receiving the one or more downlink transmissions. In such examples, the UE may wake up from the state of sleep at a first time that is at least a threshold period of time before a second time corresponding to a beginning of the one or more downlink transmissions. After waking up from the state of sleep, the UE may activate a notch filter and use the activated notch filter to filter a spur generated at the UE. The UE may receive the one or more downlink transmissions with improved reliability based on activating the notch filter.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station and in a first slot, an indication of a signal to noise ratio (SNR) mode, of a plurality of SNR modes, to be used by the UE for one or more downlink communications in one or more slots that occur after the first slot, wherein different SNR modes of the plurality of SNR modes support at least one of different modulation and coding schemes, different ranks, or a combination thereof; and operate using the SNR mode in the one or more slots based at least in part on the indication. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink control message from a base station indicating a modulation and coding scheme (MCS) associated with an uplink transmission, a number of layers associated with the uplink transmission, or both. The UE may determine to adjust (for example, reduce) a first number of bits based on the MCS, the number of layers, or both. The first number of bits may include an effective number of bits (ENOB) supported at a digital-to-analog converter (DAC) of the UE, a number of bits (NOB) supported at a transmission front end (TxFE) component of the UE, or both. The UE may transmit the uplink transmission to the base station according to the adjusted first number of bits.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may receive, using a first receive port, a first signal within a first frequency band, where the first receive port may be associated with a first receive beam. The wireless device may also receive, using a second receive port, a second signal within the first frequency band concurrently with receiving the first signal, where the second receive port may be associated with a second receive beam. After receiving the first and second signals, the wireless device may process both signals. Processing the signals may include decoding both of the signals, measuring both of the signals, and/or decoding one of the signals and measuring the other of the signals. To support concurrent reception over multiple receive beams within a single frequency band, the wireless device may employ an idle antenna panel and corresponding receive ports.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify conditions associated with one or more physical channels, for example, a set of resources with which the UE may be configured to communicate with a base station. The UE may determine whether to enable a reduced power mode based on the conditions satisfying certain criteria, for example, the set of resources corresponding allocated for particular transmissions. The UE may identify that the conditions satisfy corresponding criteria, and the UE may determine to enable the reduced power mode. The UE may accordingly modify operations one or more components of a receive chain of the UE. The UE may determine to disable the reduced power mode based on the conditions failing to satisfy the criteria, and the UE may modify operations of the one or more components of the receive chain accordingly.
