Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured with a first configuration that the UE is to use for semi-persistent scheduling transmissions when availability of one or more uplink symbols in which the feedback is scheduled for transmission to a base station changes (e.g., due to a slot format change). The UE may be configured to defer transmission of the feedback until a subsequent uplink resource. The UE may receive, from the base station, an indication of a second configuration that the UE is to use for the semi-persistent scheduling transmissions when availability of one or more uplink symbols in which the feedback is scheduled for transmission to a base station changes. The UE may not defer transmission based on the second configuration.

Abstract: Aspects relate to reporting timing adjustment for full-duplex (FD) communications. A method by a user equipment (UE) may include receiving a first timing advance signal from a base station, determining, based on the first timing advance signal, a timing difference between a downlink signal and an uplink signal is not within a threshold, transmitting a timing report to the base station, including the determined timing difference, and receiving, from the base station, an updated timing advance signal for full-duplex (FD) communication based on the timing report.

Abstract: Methods, systems, and devices for wireless communications are described. A first network node may receive a control message identifying at least one symbol or at least one slot to be used for subband full duplex communications at a second network node. The first network node may receive a first indication of uplink resources for uplink communications during the at least one symbol or the at least one slot. The first network node may receive a second indication of downlink resources for downlink communications during the at least one symbol or the at least one slot. The first network node may communicate with the second network node during the at least one symbol or the at least one slot in accordance with one of the first indication or the second indication based on one or more prioritization rules.

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication at a user equipment. The UE receives an indication from a base station that a medium access control-control element (MAC-CE) activation of a pathloss reference signal is enabled. The UE receives a MAC-CE activating the pathloss reference signal. The UE determines the pathloss reference signal based on the MAC-CE and the indication that indicates that the MAC-CE activation of the pathloss reference signal is enabled. Then, the UE estimates a downlink pathloss based on the pathloss reference signal that is activated by the MAC-CE.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive, from a network node, control signaling indicating a first downlink bandwidth part (BWP) and a first uplink BWP, or a first downlink sub-band and a first uplink sub-band, or both, for performing sub-band full-duplex (SBFD) communications. The UE may receive, from the network node, a downlink control information (DCI) message indicating to switch to a second downlink BWP and a second uplink BWP, or to switch to a second downlink sub-band and a second uplink sub-band, or both. The UE may then perform full-duplex communications with the network node within the second downlink BWP and the second uplink BWP, or within the second downlink sub-band and the second uplink sub-band, or both.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for signaling user equipment (UE) capability for sharing quasi co-location (QCL) parameter across a group of frequency bands. For example, the UE may report, to a network entity, a capability of the UE to apply a common spatial QCL parameter for at least one group of frequency bands. The UE receives an indication of a change to the common transmission control indicator (TCI) states or spatial relation parameter to be applied across the group of frequency bands. The UE applies the change across the group of frequency bands.

Abstract: Techniques for signaling uplink transmission configuration indicator (TCI) states are disclosed. In an example, a base station may determine one or more capabilities of a user equipment (UE). The base station may also determine one or more uplink TCI states for the UE to use based on the one or more capabilities. The base station may also transmit, to the UE, signaling of the one or more uplink TCI states.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, in a full duplex transmission mode, at least one downlink control information (DCI) transmission for scheduling an uplink communication and a downlink communication, wherein the at least one DCI transmission indicates a full duplex beam pair including a first beam associated with the uplink communication and a second beam associated with the downlink communication. The UE may communicate with at least one wireless communication device based at least in part on the uplink communication and the downlink communication. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a source base station (BS), a handover message or the beam or panel selection message including multi-beam or multi-panel information identifying a first one or more beams or panels to remain with the source BS and a second one or more beams or panels to switch from the source BS to a target BS during a handover procedure. The UE may perform the handover procedure to switch from the source BS to the target BS with the first one or more beams or panels for communication with the source BS and the second one or more beams or panels for communication with the target BS. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a full-duplexing rule that indicates to refrain from using a transmission dropping rule for transmission direction conflicts that occur between uplink and downlink transmissions in a same symbol. The UE may receive a control message scheduling transmission of a message during a symbol, where a transmission direction conflict arises between a first transmission direction of the message and a second transmission direction of the symbol. For example, the UE may identify a transmission direction conflict between an uplink transmission direction of the message and a downlink transmission direction of the symbol. The UE may communicate the message during the symbol based on the full-duplexing rule. The described techniques may enable the UE to attain reduced latency and higher throughput based on reducing a number of transmissions dropped by the UE.
