Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) supporting full duplex communications may determine that a set of downlink messages to be transmitted from a base station to the UE overlaps in time with a set of uplink messages to be transmitted from the UE. Accordingly, the UE may determine a downlink transmission power adjustment value for the set of downlink messages. In some examples, the base station may indicate the downlink transmission power adjustment value to the UE via radio resource control (RRC) signaling, a downlink control information (DCI) message, or both. The UE may transmit the set of uplink messages while simultaneously receiving the set of downlink messages with a transmission power that corresponds to the downlink transmission power adjustment value. Adjusting the transmission power for the set of downlink messages may reduce self-interference at the UE, the base station, or both.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein relate to schemes for managing an overlap of at least part of a tracking reference signal (TRS) with an uplink subband or a guard band in a subband full duplex (SBFD) slot or symbol. In some examples, if a user equipment (UE) and/or a network entity determines that at least a portion of a TRS is scheduled for reception in an uplink subband or a guard band of an SBFD slot or symbol, the UE and/or the network entity may: drop the TRS, puncture the portion of the TRS that overlaps with the uplink subband or the guard band; or may shift the frequency position of the TRS such that the TRS is scheduled within the downlink subband(s) of the SBFD slot or symbol.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information associated with downlink reception in an uplink subband corresponding to a subband full duplex (SBFD)-aware configuration. The UE may receive a downlink communication in the uplink subband based on the configuration information. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support resource restrictions for sub-band full duplex (SBFD) and dynamic time division duplex (TDD) operations. For example, a user equipment (UE) may receive, from a network entity, control signaling indicating a restriction to one or more slots associated with communications between the UE and the network entity. Each of the one or more slots may be associated with one or more sub-bands and the restriction may modify an availability of a duplexing setting for at least a portion of the one or more sub-bands. Additionally, the UE may communicate with the network entity via at least a subset of the one or more sub-bands of the one or more slots in accordance with the restriction.

Abstract: Methods, systems, and devices for wireless communications are described. For example, an operator may utilize the duplexing gap as a second downlink channel for an operator that has an uplink channel next to the guard. an operator may utilize the duplexing gap as a second uplink channel for an operator that has a downlink channel next to the guard. In some examples, a new block may be added for an operator (e.g., the first operator, the second operator, or a third and distinct operator). The new block may include an uplink channel and a downlink channel (which are adjacent to respective uplink and downlink channels for other operators, hence avoiding additional interference). A new block may be added for an operator (e.g., the first operator, the second operator, or a third and distinct operator), which may be subdivided in time, frequency, or both.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may support partial monitoring of control resource sets (CORESETs) that overlap with uplink subbands in a full duplex time interval under certain conditions. The UE may monitor physical downlink control channel (PDCCH) candidates in the downlink subband and ignore PDCCH candidates in the uplink subband. In some examples, a UE may support monitoring of CORESETs that overlap with the uplink subbands. In such examples, the UE may assume that symbols containing CORESETs are downlink symbols (e.g., such that the symbols of the CORESET overlapping with the uplink subband are used as downlink symbols).

Abstract: Methods, systems, and devices for wireless communications are described. A network entity may implement a subband full duplex communication scheme. For a half duplex UE, each slot may be configured as either a downlink slot or an uplink slot. A half duplex UE may be scheduled with a transmission in a conflicting (e.g., opposite) direction with respect to the configured slot direction for the UE. The UE may determine whether to communicate a scheduled transmission in a conflicting direction of the configured slot direction in accordance with a conflict resolution scheme. A UE may receive scheduling information for a second transmission that is scheduled for the same direction as the slot in addition to the transmission scheduled for the opposite direction as the slot. The UE may apply the conflict resolution scheme to determine which transmission to communicate.

Abstract: A base station may configure a Doppler tracking sounding reference signal (SRS) resource set with different time gaps between SRS resources of the Doppler tracking SRS resource set. However, factors influencing an optimal time gap for uplink Doppler parameter estimation may change over time and may depend on a Doppler parameter to be estimated. Therefore, parameters of an aperiodic Doppler tracking SRS resource set configuration may become suboptimal for estimating uplink Doppler parameters. Some techniques and apparatuses described herein enable dynamic parameter adaptation for aperiodic Doppler tracking SRS resource sets. The base station may dynamically adapt one or more parameters for an aperiodic Doppler tracking SRS resource set to modify a time gap and/or a number of resources or symbols to be transmitted for an aperiodic Doppler tracking SRS resource set. The base station may transmit downlink control information that indicates the one or more parameters.

Abstract: Bandwidth part (BWP) configurations supporting various communication approaches (e.g., full duplex and/or half duplex operations) are described. Full duplex (FD) frequency-based BWP configurations may, for example, be configured as a subset of defined BWP resources for supporting full duplex operation by base stations and/or user equipments (UEs). Usable bandwidth of a FD frequency-based BWP configuration may be selected from half duplex frequency-based BWPs in legacy BWPs. Bandwidths of usable BWPs for a FD frequency-based BWP configuration may be selected so as to be non-overlapping in frequency. Transition between configurations and modes (e.g., between full duplex frequency-based BWP configurations, between half duplex and full duplex modes, etc.) may be managed to avoid periods in which a communication device cannot perform any uplink or downlink transmissions due to switching between defined BWP configurations, or otherwise reduces BWP switching time.

The UE may transmit, to the base station, the SRS information during the select available slot, determined based at least in part on the slot information and the configuration information. Numerous other aspects are described.

A user equipment (UE) may receive, from a wireless network device (e.g., a base station or a transmission reception point (TRP) of the base station), a first control message comprising an indication of a set of energy saving modes of the wireless network device. The UE may receive a second control message indicating a first energy saving mode from the set of energy saving modes, where the first energy saving mode may be indicative of a number of channel state information (CSI) reference signal (CSI-RS) resources used by the wireless network device. The UE may monitor one or more of the CSI-RS resources for a CSI-RS in accordance with the first energy saving mode, and transmit, to the wireless network device, CSI feedback determined based on measurements made by the UE of the CSI-RS.
