Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive, from a base station, control signaling indicating a set of connected discontinuous reception (C-DRX) configurations. The set of C-DRX configurations may include a first C-DRX configuration and a second C-DRX configuration, where at least one C-DRX configuration in the set of C-DRX configurations is a UE-group common C-DRX configuration. The set of C-DRX configurations may correspond to a discontinuous transmission (DTX) cycle of the base station. The UE may select a C-DRX configuration from the set of C-DRX configurations based on receiving the control signaling from the base station. Accordingly, the UE may use the selected C-DRX configuration to communicate with the base station. The selected C-DRX configuration may enable the base station to operate with reduced power consumption and higher DTX efficiency, among other benefits.

Abstract: Methods, systems, and devices for wireless communications are described. In a multilevel encoding scheme, a transmitting device may divide a stream of information bits in a message into multiple substreams, and the transmitting device may input each substream to a different level of an encoder such that each substream is encoded separately. The transmitting device may also input excess bits to some levels of the encoder to add physical layer security to the message. To improve the chances that a receiving device is able to correctly decode the message, the receiving device may be configured to identify the levels at which the excess bits are encoded. Accordingly, the receiving device may be able to decode the information bits in the message and avoid attempting to decode the excess bits in the message as information bits.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may operate in accordance with a full-duplex communication mode and may be scheduled for an uplink transmission without a simultaneous downlink reception. For example, the UE may actively operate both a first one or more antenna panels for transmission and a second one or more antenna panels for reception and, in scenarios in which the UE is performing an uplink transmission without simultaneously receiving a downlink transmission, the UE may use self-interference from the uplink transmission at the second one or more antenna panels for energy harvesting. For example, the UE may receive the self-interference associated with the uplink transmission at the second one or more antenna panels, may refrain from applying interference cancellation, and may instead use a received energy from the self-interference to power one or more components of the UE.
