Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine an actual power delay profile (PDP) associated with a channel between the UE and a base station, wherein the actual PDP indicates an averaged power level of the channel over a period of time. The UE may determine whether a channel estimation mode switching event is satisfied. The UE may switch, based at least in part on the channel estimation mode switching event being satisfied, between a first channel estimation mode based at least in part on the actual PDP and a second channel estimation mode based at least in part on a template PDP. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication between a first wireless device and a second wireless device are described. A second wireless device may determine that a channel condition satisfies at least one channel condition threshold. The second wireless device may identify, based on the determination, a time-interleaved transmission scheme for block(s) of encoded information. The second wireless device may transmit the block(s) of encoded information to a first wireless device in accordance with at least the time-interleaved transmission scheme. In some instances, the first wireless device may determine that the channel condition satisfies the at least one channel condition threshold and send a message to the second wireless device in order to trigger the use of the time-interleaved transmission scheme.

Abstract: Techniques are described for wireless communication at a wireless communication device. A determination may be made regarding the number of receive chains, of a plurality of receive chains, to enable for a channel. Power to the receive chains may be regulated based on the determined number of enabled receive chains. The determination may be based on a transmission scheduling rate for the wireless communication device and a rank for the channel. In some examples, the determination may further be based on a channel quality of the channel and/or a type of traffic scheduled for the channel.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may update a noise estimation (e.g., a noise covariance matrix, a log likelihood ratio (LLR) scaling, or both) for communications with a serving base station to account for interference from a neighboring base station operating according to a different radio access technology (RAT). For example, the UE may identify a transmission status of a base station operating according to a first RAT, such as long term evolution (LTE), that shares a radio frequency spectrum with a serving base station operating according to a second RAT, such as new radio (NR). The UE may measure the interference from the LTE base station and may update a noise estimation according to the measured interference. The UE and the serving base station may communicate based on the updated noise estimation.

Abstract: Methods, systems, and devices for wireless communications are described. A scheduled entity transmits an indication of frequency resources that have different transmission requirements from those of other frequency resources in a smallest frequency domain scheduling unit that comprises the frequency resources for the scheduled entity. The scheduled entity receives, from a scheduling entity, signaling indicating at least one characteristic of how a channel is to be scheduled on the frequency resources from a scheduling entity. The scheduled entity communicates with the scheduling entity in accordance with the at least one characteristic.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment may receive signaling that indicates one of a plurality of demodulation reference signal (DMRS) configurations for demodulating a downlink data channel in a slot or subslot. The UE may receive the signaling from a network entity, such as a base station, and the network entity may select the indicated DMRS configuration. The plurality of DMRS configurations may indicate whether DMRS combining is supported across the slot or subslot and a subsequent adjacent slot or subslot, and the plurality of DMRS configurations may include a configuration that is capable of indicating to the UE that a single DMRS is configured in the slot or subslot and is to be combined with a DMRS in a subsequent adjacent slot or subslot to demodulate the downlink data channel.
