Abstract: Example aspects include a method, apparatus, and computer-readable medium for scheduling transmissions of transport blocks (TBs) at a base station of a wireless communication network, comprising accessing static transmission information indicating configuration information of TB transmissions. The aspects further include transmitting, to a user equipment (UE), first downlink control information (DCI) corresponding to a first transmission. Additionally, the aspects include transmitting, to the UE according to the static transmission information and the first DCI, the first transmission comprising at least a portion of encoded bits of the TB. Additionally, the aspects include receiving, from the UE, an indication of at least one code block that failed to be successfully decoded. Additionally, the aspects include transmitting, to the UE, second DCI corresponding to a second transmission. Additionally, the aspects include retransmitting, to the UE according to the static transmission information, the first DCI, and the second DCI.

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, an indication to operate in a dynamic demodulation reference signal (DMRS) mode, wherein the dynamic DMRS mode includes a use of dynamic DMRS configurations without an explicit indication of DMRS resource locations for the dynamic DMRS configurations. The UE may receive, from the base station based at least in part on receiving the indication to operate in the dynamic DMRS mode, a DMRS using a first dynamic DMRS configuration. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide a technique for wireless communications by a user equipment (UE). The UE implements the technique to detect that a decoding failure of a first multiple input multiple output (MIMO) transmission, sent by a network entity on a first number of layers, is caused by a rank mismatch. The UE then sends a rank correction request to a network entity. The UE then combines samples from the first MIMO transmission and a second MIMO transmission, sent by the network entity using a space-time code (STC) with a second number of layers in response to the rank correction request, to recover data lost due to the decoding failure.

Abstract: Aspects of a methods, apparatus, and computer-readable medium for wireless communication at a wireless device are provided herein. The wireless device may receive a configuration for a resource pool for sidelink communication, the resource pool having a plurality of physical resource blocks (PRBs) including a first set of PRBs that are grouped in one or more sub-channels, each sub-channel having an equal number of PRBs, and a second set of PRBs that are not in the one or more sub-channels having the equal number of PRBs. The apparatus may transmit in the second set of PRBs. The second set of PRBs may not be monitored by a receiving device.

Abstract: Certain aspects of the present disclosure provide techniques for training a digital pre-distorter (DPD) using real-time over-the-air transmissions and receptions by a user equipment (UE). A method for training the DPD generally includes transmitting a signal, generated by a transmitter front end, via a first port; sampling the signal, received over the air, at a second port; performing signal processing cleaning (e.g., synchronization, linear over-the-air channel estimation and equalization); calculating coefficients for a DPD; and configuring the DPD with the coefficients, for use in digitally pre-distorting sub sequent transmissions.

Abstract: Certain aspects of the present disclosure provide techniques for mapping two-stage sidelink control with multiple layer sidelink data channel. A first user equipment (UE) can rate-match a multiple-layer second stage of a two-stage sidelink control information (SCI) transmission as a single layer. The first UE transmits the multiple-layer second stage of the two-stage SCI, to a second UE, using multiple antenna ports.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless device may receive a beamformed signal from a transmitting device. The wireless device may estimate a weighted sum based at least in part on one or more coefficients that relate to impairments associated with the transmitting device, a spatial location of the wireless device, and/or the like. The wireless device may determine a cryptographic key based at least in part on a ratio among the plurality of coefficients in the weighted sum, and one or more communications between the wireless device and the transmitting device may be secured based on the cryptographic key. Numerous other aspects are provided.

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 base station may mitigate the link adaptation convergence transient upon performing a beam switch by modifying the modulation and coding scheme (MCS) according to a difference in reference signal received power (RSRP) between the old beam and the new beam. The base station may further adjust the MCS utilizing an outer-loop link adaptation process or channel state feedback (CSF) provided by the UE after the beam switch. Other aspects, features, and embodiments are also claimed and described.

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.
