Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may identify a set of data resource elements for transmitting data in one or more symbols periods. The first wireless device may generate, for the one or more symbol periods based on the set of data resource elements, a sequence of a set of pilot resource elements associated with the set of data resource elements, the sequence of the set of pilot resource elements including a demodulation reference signal. The first wireless device may transmit, to a second wireless device in the one or more symbol periods, the set of data resource elements and the set of pilot resource elements. The second wireless device may decode a first subset of the set of pilot resource elements based on a second subset of the set of pilot resource elements to determine the demodulation reference signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a second UE and using a first fast Fourier transform (FFT) window configuration, a physical sidelink control channel (PSCCH) signal associated with a physical sidelink shared channel (PSSCH) signal. The UE may identify, based at least in part on the reception of the PSCCH signal, one or more values of one or more parameters estimated from the PSCCH signal. The UE may select, based at least in part on the one or more values of the one or more parameters, a second FFT window configuration to be used to receive the PSSCH signal. The UE may receive, from the second UE, the PSSCH signal using the second FFT window configuration, Numerous other aspects are described.

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: A method or apparatus for wireless communication at a wireless device. The wireless device transmits or receives an indication of support for using a set of remaining physical resource blocks (PRBs) in a resource pool including one or more sub-channels having an equal number of PRBs and the set of remaining PRBs that are not in the one or more sub-channels having the equal number of PRBs. The wireless device transmits or receives sidelink communication in the set of remaining PRBs.

Abstract: In order to enable asynchronous, autonomous reception beam switching at a UE while minimizing degradation due to a transient in link performance, a method, apparatus, and computer-readable medium for wireless communication are provided. The apparatus receives CSI-RS on different reception beams in different symbols, wherein one reception beam being a current serving reception beam, and determines whether to switch to a different reception beam based on a SPEFF metric for the different reception beam and/or a severity of a potential link transient qualified in terms of the expected CQI/MCS degradation in the channel. The apparatus may switch from a current serving reception beam to a second reception beam when a first channel quality for the current serving reception beam is within a threshold value of a second channel quality for the second reception beam, the second channel quality being measured using a current configuration.

Abstract: Aspects of the disclosure relate to minimizing the block error rate (BLER) experienced by a user equipment (UE) upon a downlink beam switch at the base station. The UE may measure the reference signal received power (RSRP) of each of a plurality of downlink beams during a beam sweep and modify an automatic gain control (AGC) state of the UE based on the difference in RSRP between a current downlink beam and an expected downlink beam expected to be selected by the base station for subsequent unicast downlink transmissions to the UE. In some examples, the expected downlink beam may have a highest RSRP among all of the measured RSRPs of the different downlink beams Other aspects, features, and embodiments are also claimed and described.
