Abstract: Methods, systems, and devices for wireless communication are described. A base station may transmit or otherwise indicate a semi-static slot format configuration and a dynamic slot format configuration to a user equipment (UE). The UE may determine a slot format configuration based on the received semi-static and dynamic slot format configurations. In some cases, the UE may replace certain resources of the semi-static slot format configuration with resources from the dynamic slot format configuration depending on a certain embodiment. Additionally or alternatively, the base station may transmit an anchor slot configuration to the UE, which may indicate which resources of the semi-static slot format configuration can be overridden or replaced by the dynamic slot format configuration.

Abstract: The position of a target user equipment (UE) is determined using an anchor UE and sidelink communication signals transmitted from the target UE to the anchor UE. During a positioning session, the anchor UE receives from the target UE sidelink communication signals, such as data signals and/or data related reference signals. The anchor UE performs positioning measurements for the sidelink communication signals from the target UE, such as timing based, angle based, or power based measurements. The anchor UE provides the positioning measurements of the sidelink communication signals to a location server, which may use the positioning measurements, along with a known position of the anchor UE to determine the position of the target UE.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting user equipment (UE) may determine a set of resources for sidelink communication with one or more neighboring UEs. The transmitting UE may transmit multiple sidelink control messages to the neighboring UEs indicating the set of resources are reserved for a sidelink data message. The neighboring UEs may receive at least one of the sidelink control messages. A neighboring UE may determine a portion of the resources are reserved for a sidelink data message with the transmitting UE and may transmit or receive the sidelink data message using the portion of the resources. Additionally or alternatively, a neighboring UE may determine the resources are reserved for a sidelink data message between the transmitting UE and another neighboring UE and may select alternative resources for sidelink data messages to may avoid using the reserved resources.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling configuring the UE with a set of frequency resources and a semi-persistent resource allocation indicating a semi-persistent resource occasion on each frequency resource of the set. The UE may monitor semi-persistent resource occasions on each of the set of frequency resources for a copy of a data transmission. If the UE receives and decodes the data transmission from at least one of the semi-persistent resource occasions, the UE may transmit an acknowledgement message on a frequency resource of the set. Additionally, the UE may refrain from transmitting a feedback message on the other frequency resources of the set. If the UE does not receive and successfully decode the data transmission from any of the semi-persistent resource occasions, the UE may transmit a negative acknowledgement message on one of the set of frequency resources.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may monitor for sidelink messages among multiple UEs using transmission-side sensing. The first UE may monitor for sidelink messages over a transmit beam selected for transmitting data from the first UE. The first UE may receive, from a second UE, a sidelink message including an indication of resources reserved for sidelink transmissions to the second UE. Based on the indication, the first UE may select available resources over which to transmit data. The first UE may receive the sidelink message over a sidelink feedback channel.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may receive a configuration of a set of feedback channel occasions corresponding to a first sidelink data channel in a first listen-before-talk (LBT) sub-band, the set of feedback channel occasions located over multiple LBT sub-bands of an unlicensed radio frequency spectrum band. The UE may receive a data transmission over the first sidelink data channel and may determine to transmit feedback associated with the data transmission. The UE, based on the configuration of the set of feedback channel occasions, may perform LBT for each of the set of feedback channel occasions to determine which of the set of feedback channel occasions are available to the UE for transmitting the feedback associated with the data transmission. The UE may transmit feedback over one or more of the set of feedback channel occasions accordingly.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support use of common sequence pools for non-coherent transmissions according to one or more aspects. In a first aspect, a method of wireless communication includes converting, by a wireless communication device, an information bit stream to an integer value. The method also includes selecting, by the wireless communication device, a sequence from a common sequence pool based on the integer value. The common sequence pool has a nested structure of sequences which map different length information bit streams with the same most significant bit or bits to the same sequences. The method further includes transmitting, by the wireless communication device, a non-coherent transmission indicating the sequence. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. In some implementations, a method for wireless communication at a user equipment (UE) is described that includes identifying that the UE is in carrier aggregation communication with a primary and secondary cell. The method may also include monitoring, during one or more time intervals, UE-specific search spaces of the secondary cell for control information scheduling data communications on the primary cell. The method may include switching, during one or more different time intervals, to monitoring UE-specific search spaces of the primary cell. Another method describes wireless communication at a base station that may configure a UE to communicate via carrier aggregation, transmit control information via the secondary cell to the UE during downlink TTIs, and transmit control information via the primary cell to the UE during uplink TTIs.

Abstract: Methods, systems, and devices for wireless communications are described. For example, the described techniques provide for configuring sidelink beam failure detection reference signals for determining beam failures on a sidelink between a first sidelink user equipment (UE) and a second sidelink UE. The first UE may determine a first set of sidelink beam failure detection reference signals to transmit to the second UE and a second set of sidelink beam failure detection reference signals to receive from the second UE. The first UE may transmit the first set to the second UE using a set of sidelink transmit beams. The first UE may further monitor for the determined second set using a set of sidelink receive beams. Based on the first and second set of sidelink beam failure detection reference signals, the first and second UE may communicate over the sidelink.
