Abstract: Aspects of the present disclosure provide for the pairing of an inter-band carrier with a time division duplex (TDD) carrier. If the paired band is a frequency division duplex (FDD) band, then base stations and mobile devices may transmit and receive additional thin control channels on FDD carriers to enable full duplex operations. If the paired band is a TDD band, then a conjugate or inverse carrier may be used such that full duplex, or a close approximation thereto, is achieved. With the introduction of a paired channel and fast control channels, rapid uplink/downlink switching may be achieved for TDD carriers efficiently and effectively. Other aspects, embodiments, and features are also claimed and described.

Abstract: Aspects relate to supporting power control for physical uplink control channel (PUCCH) transmissions on an uplink secondary component carrier (SCC) of a wireless communication system. In some aspects, a user equipment (UE) receives a power control configuration from a base station for use by the UE for a PUCCH transmission on a selected uplink SCC. The UE then transmits, based at least in part on the power control configuration, the PUCCH to the base station on the selected uplink SCC. Closed-loop and open-loop power control examples are provided. In some aspects, common or shared power control configurations are provided by the base station for use with each component carrier of a PUCCH group. In other aspects, carrier-specific power control configurations are provided by the base station.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station via a reconfigurable surface, a set of reference signals reflected by the reconfigurable surface using a set of precoder configurations. In some aspects, the set of reference signals are transmitted within a set of reference signal occasions of a sweep procedure associated with configuring the reconfigurable surface with different precoder configurations of the set of precoder configurations for reflecting signals. The UE may additionally transmit, to the base station via the reconfigurable surface, a feedback message including an indication of at least one precoder configuration of the set of precoder configurations based on receiving the set of reference signals. The UE may then receive, from the base station via the reconfigurable surface, a downlink transmission based on transmitting the feedback message.

Abstract: Techniques and apparatus for determining a transport block (TB) configuration and hybrid automatic repeat request (HARQ) acknowledgment (ACK)/negative acknowledgment (NACK) configuration for full duplex (FD) UE(s) are described. One technique involves receiving channel state information (CSI) report(s) from a UE operating in FD mode. At least one of a TB configuration or feedback type for a communication slot is determined based on the CSI report(s). The communication slot can include half duplex (HD) symbol(s) and FD symbol(s). An indication of at least one of the TB configuration or the feedback type is signaled to the UE. Another technique involves receiving, from a base station (BS), downlink data transmission(s) across a slot(s). A type of duplexing mode associated with each of the slot(s) is determined. The downlink data transmission(s) are acknowledged, based at least in part on the type of duplexing mode associated with each of the slot(s).

Abstract: Wireless communication devices, systems, and methods related to bundling of uplink communication signals under timing advance (TA) conditions are provided. For example, a method of wireless communication performed by a user equipment can include receiving, from a base station, a timing advance (TA), wherein the TA is scheduled to be implemented by the user equipment at a first time, the first time being after a start of a first uplink communication of a group of bundled uplink communications scheduled with phase coherence and before a start of a second uplink communication of the group of bundled uplink communications; determining whether to implement the TA at the first time or a second time, the second time being after transmission of the second uplink communication; and implementing the TA based on the determining.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be capable of operating according to a first transmission efficiency operating mode and a second transmission efficiency operating mode that is less power efficient than the first transmission efficiency operating mode. The first transmission efficiency operating mode may be associated with a first undesired emission level that is greater than a second undesired emission level associated with the second transmission efficiency operating mode. The UE may select to operate in one of the two transmission efficiency operating modes based on one or more communication parameters (e.g., indicated by control signaling received from a base station). For example, the UE may select to operate in the first transmission efficiency operating mode based on determining that one or more of the communication parameters satisfies at least one parameter criterion for operating in the first transmission efficiency operating mode.

Abstract: Methods, systems, and devices for wireless communications are described in which a network entity may use a lower power sleep procedure to reduce power consumption, and monitor for a wake-up signal (WUS) from at least one user equipment (UE) during configured WUS occasions. The WUS from one or more UEs may provide information of one or more attributes of data traffic that is present at a transmit buffer of the one or more UEs. A WUS configuration may be provided from a network entity that allows the selection of a particular WUS to indicate one or more attributes of the data traffic at the UE. The WUS may convey information such as buffer status, power headroom, a priority of traffic, latency targets of the traffic, or any combinations thereof. The WUS may also give an indication of a requested duration of an active mode at the network entity.

In some aspects, a user equipment (UE) may receive, from a network node, a measurement configuration indicating one or more punctured resources of a physical downlink shared channel (PDSCH) that can be used for measurements associated with estimating an interference plus noise covariance (INC) matrix at the UE. The UE may receive, from the network node, a reporting configuration indicating one or more INC matrices at the UE to be reported. The UE may transmit, to the network node, a report indicating the one or more INC matrices at the UE based at least in part on receiving the reporting configuration. Numerous other aspects are provided.
