The UE may communicate in a full duplex communication mode, wherein communicating in the full duplex communication mode comprises rate matching based at least in part on the at least one rate matching configuration. Numerous other aspects are described.

The first UE may transmit to the second UE, via an SCI-2 message in a PSSCH, an indication of at least one of a 3D zone ID associated with the first UE or a 3D communication range associated with the first UE. The second UE may determine whether the second UE is in a communication range based on the received indication of the at least one of the 3D zone ID associated with the at least one first UE or the 3D communication range associated with the at least one first UE. The second UE may determine whether to transmit an ACK or a NACK based on whether the second UE is in the communication range. The second UE may transmit to the first UE an ACK or a NACK based on whether the at least one second UE is in a communication range.
This disclosure provides methods, devices and systems for synchronized channel access. Some implementations more specifically relate to facilitating coexistence among wireless communication devices that support synchronized channel access and those that do not. A group of access points may schedule periodically recurring, synchronized channel access periods by periodically transmitting quiet elements. The quiet elements establish recurring quiet periods during which legacy devices are not permitted to transmit. In some implementations, an access point may transmit one or more quiet override elements each associated with a respective quiet element and indicating to other access points supporting synchronized channel access that they are permitted to contend for access during the respective quiet period. In some other implementations of synchronized channel access, an access point supporting synchronized channel access that wins contention after one or more consecutive synchronized channel access periods during which no other synchronized access points won contention, may be entitled to an extended TXOP.
This disclosure provides systems, methods, and devices for memory systems that support metadata. In a first aspect, a method of handling data and metadata at a memory device includes receiving data from the host via the at least one data connection into the first plurality of registers; receiving metadata from the host via the at least one non-data connection into the second plurality of registers; storing the data in the first portion of the memory array; and storing the metadata in the second portion of the memory array. Other aspects and features are also claimed and described.
An example device for decoding video data includes: a memory configured to store video data; and a processing system comprising one or more processors implemented in circuitry, the processing system being configured to: determine whether motion information of a block of video data is for sub-blocks of the block larger than individual pixels of the block or for the individual pixels, the block being associated with data indicating that the block is to be predicted using affine motion compensation; in response to determining that the motion information of the block is for the sub-blocks, perform sub-block-based affine motion compensation to form a prediction block for the block; in response to determining that the motion information is for the individual pixels, perform pixel-based affine motion compensation to form the prediction block for the block; and decode the block using the prediction block.

Certain aspects of the present disclosure provide techniques for adaptive antenna mode switching. An example method performed by a wireless device includes reporting first capability information indicating that the wireless device supports a first antenna mode associated with a first number of receive antennas, detecting radio conditions that favor a second antenna mode associated with a second number of receive antennas, and performing one or more actions to cause a switch to the second antenna mode based on the detected radio conditions.
Methods, systems, and devices for wireless communications are described. The method may include a user equipment (UE) monitoring a set of time resources for a set of code blocks and receiving, from a network entity, a code block of the set of code blocks via an optical beam. Further, the method may include the UE modulating the optical beam based on receiving the code block and sending, to the network entity, the modulated optical beam including feedback associated with at least one code block of the set of code blocks.
Certain aspects of the present disclosure provide a method of wireless communication at a user equipment (UE), generally including obtaining a signal indicating the UE should be awake for an upcoming discontinuous reception (DRX) ON duration; and monitoring for downlink control information (DCI) in the DRX ON duration, according to an indication in the signal of at least one periodicity of DCI monitoring occasions (MOs) for the DRX ON duration.
