Abstract: Aspects of the present disclosure also allow for a more efficient way to correct or compensate for IQ mismatch in an environment with multiple TX antennas and multiple IQ modulators. In these environments, a received signal is a beamformed signal which is a combination of all TX antennas passing through different channels and may be received in a single RX antenna. Specifically, the RX side may estimate the composite FDRSB for the TXs and signal back a composite FDRSB to allow the TX to use a single filter to compensate for the composite FDRSB. The composite FDRSB may correspond to the equivalent FDRSB received as a sum of the individual FDRSBS of each of the IQ modulators and IQ antennas at a base station.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for early termination of decoding attempts, including decoding attempts associated with physical downlink control channel (PDCCH) candidates that are encoded using a rateless code. In some aspects, a transmitting device may encode a message using a rateless code associated with a cumulative encoding of various portions of the message, and using a device identifier or group identifier as an input to the encoding. Similarly, a receiving device may receive an encoded signal over candidate resources and may attempt to decode the signal in accordance with the rateless code and using a device identifier or a group identifier as an input to the decoding. As such, intended or non-intended receiving device may be able to evaluate whether to proceed with a decoding attempt or to terminate a decoding attempt at a relatively early stage.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter device may transmit, to a receiver device, an initial message associated with a communication using a first code rate. The transmitter device may receive, from the receiver device, first feedback information indicating that the communication was not successfully decoded by the receiver device. The transmitter device may transmit, to the receiver device based at least in part on the reception of the first feedback information, one or more retransmissions associated with the communication including a first retransmission, wherein the first retransmission includes a first number of bits to lower an effective code rate of the communication to a second code rate. The transmitter device may receive, from the receiver device, second feedback information indicating that the communication was successfully decoded by the receiver device. Numerous other aspects are described.

Abstract: A network node may transmit a training signal for a UE on a plurality of sub-carriers, the training signal transmitted via multiple IQ modulators and multiple RF antenna panels and receive a feedback associated with an FDRSB based on the training signal. The network node may apply an FDRSB correction filter to at least one signal to be transmitted to the UE, and the FDRSB correction filter may be based on the feedback received from the UE. The training signal may include at least one tone transmitted on a first subset of sub-carriers of the plurality of sub-carriers, the first subset of sub-carriers being configured symmetric to a second subset of sub-carriers with respect to a center frequency of the plurality of sub-carriers, and the second subset of sub-carriers being free of the at least one tone of the training signal.

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 having one or more antenna ports, a communication that includes one or more data streams and a tone reservation signal, wherein a number of the one or more antenna ports is different than a number of the one or more data streams. The UE may perform channel estimation based at least in part on the communication. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques provide for reliable signal processing and amplification of downlink signals. A network entity may apply a digital pre-distortion (DPD) process to a signal for transmission to a user equipment (UE) and may apply a crest factor reduction (CFR) process to the output of the DPD process. The output of the CFR process may be amplified by a power amplifier and transmitted via a downlink transmission to the UE. The CFR process limits the peak power of the signal provided to the power amplifier (e.g., to a configured level), thereby reducing the peak to average power ratio (PAPR) of the signal provided to the power amplifier. The DPD process may compensate for non-linearities of the power amplifier. A training procedure for the DPD process may account for the CFR process applied after the DPD process.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive data encoded based on a multi-level balanced code, codewords of the multi-level balanced code being selected based on a finite number of multiple sum values, corresponding to all constellation symbol sequences in the multi-level balanced code. The UE may receive a superimposed pilot (SIP) using communication resources occupied by the data. The UE may estimate one or more channel parameters based on the SIP and the multi-level balanced code. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a user equipment (UE) may receive a control signal allocating downlink resources and uplink resources, where the uplink resources puncture the downlink resources and are allocated for transmitting feedback control information. The UE may generate an uplink signal containing the feedback control information and one or more cancelation tones for canceling interference between a downlink signal and the uplink signal in accordance with a timing advance value. Additionally, or alternatively, the UE may generate an uplink signal including the feedback control information, where the uplink signal contains uplink symbols and cyclic extensions appended to the uplink symbols, and the cyclic extensions may be based on the timing advance value. The UE may transmit, while receiving downlink data on the downlink resources, the uplink signal including the feedback control information using the set of uplink resources.

Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) may be configured to use intra-message antenna selection diversity (ASD). The UE may transmit a first portion of a scheduled message within a time interval using a first antenna element of the UE based on an intra-message antenna diversity configuration. The intra-message antenna diversity configuration may indicate a set of antennas available for transmission of the scheduled message. In some cases, the UE may transmit, within the same time interval, at least a portion of the scheduled message using at least a second antenna element of the UE that is different from the first antenna element. In some cases, a receiving UE may decode the first portion and the second portion of the scheduled message based on the intra-message antenna diversity configuration.
