Abstract: This disclosure provides systems, methods, and devices for wireless communication that support dormant bandwidth part (BWP) configurations that may be used for full-duplex operation. In a first aspect, a user equipment (UE) in a full-duplex mode may, in at least one symbol, receive a downlink signal in a dormant downlink BWP and transmit an uplink signal in an uplink BWP. In a second aspect, a dormant downlink BWP may be further configured into one of multiple possible resource bandwidths (RBWs), which may include at least one dormant RBW. Each of the multiple RBWs that may be configured in the dormant BWP may be associated with a size and location as well as a set of one or more operational constraints. In a third aspect, a dormant downlink BWP may be further configured into one of multiple possible RBWs, which may include a downlink dormant RBW and an uplink dormant RBW.

Abstract: Methods related to wireless communication systems and transmission and/or reception of synchronization signal block (SSB) transmissions are provided. In some scenarios, communications may occur in one or more full-duplex slots. For example, a wireless communication device receives a synchronization signal block (SSB) transmission schedule. The SSB transmission schedule at least partially overlapping with an uplink (UL) frequency portion of a full-duplex slot. The wireless communication device receives one or more SSBs, where the one or more SSBs are received in at least a slot different than the full-duplex slot or in a DL frequency portion of the full-duplex slot. Other features are also claimed and described.

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 communication are described. A user equipment (UE) may receive, from a base station, control signaling indicating a set of connected discontinuous reception (C-DRX) configurations. The set of C-DRX configurations may include a first C-DRX configuration and a second C-DRX configuration, where at least one C-DRX configuration in the set of C-DRX configurations is a UE-group common C-DRX configuration. The set of C-DRX configurations may correspond to a discontinuous transmission (DTX) cycle of the base station. The UE may select a C-DRX configuration from the set of C-DRX configurations based on receiving the control signaling from the base station. Accordingly, the UE may use the selected C-DRX configuration to communicate with the base station. The selected C-DRX configuration may enable the base station to operate with reduced power consumption and higher DTX efficiency, among other benefits.

Abstract: Apparatus, methods, and computer program products for SSB adaptive power transmission are provided. An example method includes performing a measurement of a medium for transmission of an SSB. The example method further includes transmitting, based on the measurement, the SSB at an SSB candidate position from a set of SSB candidate positions, wherein transmitting the SSB comprises transmitting using a first transmission power level if the measurement is within a first range and transmitting using a second transmission power level if the measurement is within a second range, the second transmission power level being lower than the first transmission power level.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to estimate a signal-to-noise ratio for each antenna port associated with a reception of one or more tracking reference signals. The UE may receive one or more of multiple single-port tracking reference signals, a single multi-port tracking reference signal, or a tracking reference signal associated with multiple power ratios. The UE may be able to estimate a channel upon receiving a demodulation reference signal. The channel estimation may be based on the reception of one or more of multiple single-port tracking reference signals, the single multi-port tracking reference signal, or the tracking reference signal associated with multiple power ratios. The UE may communicate with the base station based on estimating the channel.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a message indicating one or more communication patterns from a base station. The one or more communication patterns may indicate to the UE to adjust one or more parameters for transmitting an uplink communication during a set of time resources, a set of beams, a set of ports, or any combination thereof. During the resources indicated in the one or more communication patterns, the base station may estimate a cross-link interference channel between the base station and a second base station. The one or more communication patterns may indicate a hopping pattern for each subband of a bandwidth part. The base station may configure the UE with a timing advance based on the message.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive control signaling indicating a configuration for performing channel sensing. The configuration may include one or more parameters corresponding to a processing time associated with the channel sensing. The UE may adjust the processing time associated with the channel sensing based on the one or more parameters and a full duplex capability of the first UE. The UE may transmit, using a first set of resources, a sidelink message based on the adjusted processing time. In some examples, the UE may transmit a first data message associated with a first priority level and perform channel sensing for a second data message associated with a second priority level that is higher than the first priority level. The UE may drop the first data message, skip an interference cancellation, or a combination thereof.
