Abstract: Techniques for co-existence on a shared communication medium are disclosed. To foster co-existence, operation of a first Radio Access Technology (RAT) may be cycled between active periods and inactive periods of transmission, on a communication medium shared with a second RAT, in accordance with a Discontinuous Transmission (DTX) communication pattern. One or more cycling parameters of the DTX communication pattern may be set based on a frame structure associated with the first RAT. Transmission may proceed over the communication medium in accordance with the first RAT and the one or more cycling parameters of the DTX communication pattern.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support mechanisms for uplink traffic alignment and/or uplink traffic aggregation in wireless communication systems. A user equipment (UE) is configured with a mechanism for signaling uplink transmit opportunities to an application client using an application programming interface (API) disposed between a modem of the UE and the application client that enables uplink traffic generated by the application client to be aligned. The API includes semi-static parameters that may be used when a common timer is configured between the application client and the modem, and/or dynamic parameters that may be used when a common timer is not configured between the application client and the modem. The API may also include an extended signaling scheme that may include no-transmission (No-Tx) indications that indicate intervals during which no transmissions are allowed. These No-Tx parameters apply to the semi-static and/or dynamic signaling scheme.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may receive a control message indicating multiple power states, where each power state of the multiple power states may be associated with a configuration of the UE. Additionally, the UE may transition from a first power state of the multiple power states to a second power state of the multiple power states based on a condition being satisfied. In such cases, a first configuration of the UE associated with the first power state may be different than a second configuration of the UE associated with the second power state.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may obtain an indication of a packet data unit (PDU) set dependency pattern for at least a first PDU set and a second PDU set of a group of PDU sets, where each PDU set of the group of PDU sets is associated with a same traffic flow. The PDU set dependency pattern may indicate a relationship between the first PDU set and the second PDU set for decoding the first PDU set and the second PDU set. The wireless device may obtain the indication of the PDU set dependency pattern as part of metadata associated with the first PDU set or via a control plane message. The wireless device may obtain the group of PDU sets and may decode at least the first PDU set and the second PDU set according to the PDU set dependency pattern.

Abstract: Wireless communications systems and methods related to full-duplex cooperative communication by a first device tethered with a second device communicating with a third device. With the tether, one device between the first device and the second device is designated or selected as a transmitter, and the other device as a receiver. In full-duplex operation, the transmitter may transmit outgoing data concurrent to the receiver receiving incoming data. In an example, one of the first and second devices may have a modem that is used to control the full-duplex communication. The modem controls both transmission and reception. In another example, both devices may have a modem. Each modem may assume responsibility for part of the full-duplex communication by performing some processing before either shipping received data, or transmitting outgoing data. The amount of processing may be split at a link layer. Interference cancellation may mitigate interference from full-duplex operation.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station via a first instance of a periodic data burst, where the periodic data burst may include one or more uplink or downlink transmissions scheduled on a first bandwidth part (BWP). The UE may start a bandwidth switching timer at the beginning of the first instance of the periodic data burst, and determine whether the bandwidth switching timer has expired upon expiration of an inactivity timer that was triggered by receipt of one or more downlink control channel messages. The UE may operate, based on the determination, on one of the first BWP or a second BWP during at least a portion of a time period that extends from the expiration of the inactivity timer and a beginning of a second instance of the periodic data burst.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity may account for jitter in communications with a user equipment (UE) by adjusting connected mode discontinuous reception (CDRX) configuration parameters for the UE based on estimated downlink traffic arrival times. For a downlink traffic burst, the network entity may estimate a traffic arrival offset based on determining a traffic periodicity, an estimated arrival time associated with one or more packets of a traffic burst, and at least one jitter parameter. The jitter parameter may represent an uncertainty in the arrival time of the traffic burst. The network entity may select a CDRX offset value based on the estimated traffic arrival offset. The network entity may transmit (e.g., to a UE, such as an extended reality (XR) device) a message indicating the CDRX offset value, for example, as part of a CDRX configuration.
