Abstract: Certain aspects of the present disclosure provide techniques for wireless communications. An example method generally includes calculating a first power headroom report (PHR) for a half duplex (HD) operating mode, calculating a second PHR for a full duplex (FD) operating mode during which maximum uplink transmit power is subject to one or more self-interference constraints, determining whether to report the first PHR, the second PHR, or both, and reporting at least one of the first PHR or the second PHR to a network entity, in accordance with the determination.

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: 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: 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: 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.

Abstract: Methods, systems, and devices for wireless communications are described. In some aspects, a user equipment (UE) and a network entity may support one or more signaling-based mechanisms according to which the network entity may inform the UE of which time and frequency resources may be used for full-duplex communication. The network entity transmit a first message to configure multiple resource block (RB) sets for the UE, where each RB set is associated with unique identifying information. To inform the UE of which time and frequency resources may be used for full-duplex communication, the network entity may transmit a second message that indicates one or more slot formats on a per RB set basis. As such, the network entity may schedule the UE for full-duplex communication in accordance with indicating that overlapping symbols of a first RB set and a second RB set are allocated for uplink and downlink, respectively.
