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 dynamically adapting the mapping between spectral efficiencies and channel quality indicators in real-time based on the channel conditions. In some examples, a scheduled entity (e.g., a UE) may maintain two or more predefined tables or other mappings, each including a respective mapping between spectral efficiency threshold values and channel quality indicators for a respective channel type. The UE may then calculate respective weighted sums of the spectral efficiency threshold values across the two or more predefined tables based on the current wireless channel. For example, the UE may estimate the wireless channel and determine respective weights to be applied to the spectral efficiency threshold values across the two or more predefined tables based on the channel estimate. Other aspects, features, and embodiments are also claimed and described.

Abstract: In some aspects, a UE may select a first type of antenna for communication with a base station based at least in part on a beam management procedure that uses an RSRP parameter determined using a downlink reference signal associated with a single antenna port; measure a CSI-RS resource for CSF, associated with multiple antenna ports, using a second type of antenna and after selecting the first type of antenna; compare a first spectral efficiency parameter associated with communicating using the first type of antenna and a second spectral efficiency parameter determined based at least in part on measuring the CSI-RS resource for CSF using the second type of antenna; and select one of the first type of antenna or the second type of antenna for subsequent communication with the base station based at least in part on comparing the first spectral efficiency parameter and the second spectral efficiency parameter.

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.

Abstract: In certain aspects of the present disclosure, a method for wireless communication comprises predistorting a first signal based on a set of coefficients to generate a first predistorted signal, outputting the first predistorted signal for a first transmission to a receiving device, and receiving a first feedback signal from the receiving device, wherein the first feedback signal provides feedback of a first receive signal at the receiving device corresponding to the first transmission. The method also comprises determining whether to store the set of coefficients in a memory based on the received first feedback signal, and storing the set of coefficients in the memory based on the determination.

Abstract: Certain aspects of the present disclosure provide techniques for applying digital pre-distortion with frequency selectivity to a transmission signal. An example technique includes determining one or more target parameters of an input signal, the one or more target parameters being based on frequency of the input signal. The technique also includes applying digital pre-distortion with frequency selectivity to the input signal according to the one or more target parameters of the input signal to generate a resulting signal. The technique further includes processing the resulting signal to generate an analog signal for transmission and transmitting the analog signal.

Abstract: Methods, systems, and devices for wireless communications are described. For instance, a first device may transmit a reference signal to a second device and the second device may measure self-interference at the second device. In a first example, the second device may transmit an indication of channel state information to the first device along with an interference report including a measure of the self-interference, which the first device may use to determine an MCS and/or a rank. In a second example, the second device may determine an MCS and/or rank based on measuring the self-interference. In some examples, the second device may transmit a first indication of the MCS and/or rank determined based on measuring the self-interference to the first device along with a second indication that the MCS and/or rank is associated with full-duplex communications at the second device.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may implement techniques for receiving multiple bits of information via a single wake-up signal (WUS). For example, the UE may receive a configuration indicating a quantity of sequences associated with multiple sequences of a WUS. The UE may receive, while operating in a sleep mode, the WUS that includes multiple sequences, where each sequence is associated with a single bit and the multiple sequences indicate one or more operations. The UE may perform, while operating in the sleep mode, the one or more operations that are indicated by the multiple sequences of the WUS. In some other examples, the UE may implement multiple wake-up radios (WURs), such that the UE may receive multiple WUSs simultaneously. In some aspects, the UE may use the simultaneous WUSs received via the WURs for beam tracking or other operations.
