Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a first user equipment (UE) may monitor and perform blind decoding for a sidelink transmission, such as a first part of sidelink control information (SCI), from a second UE over a configured search space. The first UE may receive signaling indicating an update to the search space via lower layer signaling, such as via a second part of SCI or a sidelink data channel, and may monitor for the sidelink transmission over the updated search space. The update to the search space may indicate a blocking of one or more monitoring occasions from the configured search space, an addition of one or more monitoring occasions to the configured search space, a reactivation of one or more previously blocked monitoring occasions, or a switching from a first search space to a second search space.

Abstract: Techniques for location determination of user equipment (UE) are provided. In an aspect, a position estimation entity (e.g., UE, gNB, LMF, etc.) identifies a pool of UEs for a SL-assisted position estimation procedure of a set of target UEs. SL SRS-Ps are communicated (e.g., transmitted and measured) between the pool of UEs (e.g., for relative SL ranging). UL SRS-Ps are communicated by at least some of the UEs in the pool of UEs. The position estimation entity obtains measurement data for both the SL SRS-P and UL-SRS-P communications. The position estimation entity determines a position estimate for each UE in the set of UEs based on the measurement information.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor a first control resource pool associated with sidelink control signaling during a first sensing window and monitor a portion of a second resource pool associated with sidelink data signaling during a second sensing window. The UE may perform joint resource selection on the first resource pool and the second resource pool based on the monitoring during the first and second sensing windows. The UE may transmit a sidelink control information message including resource indication fields to reserve the selected sidelink control channel resources and selected sidelink shared channel resources. The UE may transmit the sidelink data message on one or more of the reserved sidelink shared channel resources.

Abstract: A wireless device, such as a PLC, receives data from at least one wireless device. The wireless device transmits first feedback for the data in a downlink control channel to the at least one wireless device and transmits second feedback for the data in an uplink control channel to a base station. The base station receives the feedback in an uplink control channel and transmits a retransmission of the data to the wireless device in response to receiving the feedback.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a first sidelink control information (SCI) message during a mini-slot of a control resource pool which is decoupled from a data resource pool for sidelink communications. The first SCI message may indicate a data message to be transmitted on a subchannel of the data resource pool to a second UE, where resources between the control resource pool and the data resource pool are mapped. The UE may receive a feedback message from the second UE for the first SCI message during a second mini-slot of the control resource pool. The feedback message may indicate whether a collision or strong interference was detected for the first SCI message. The UE may determine whether to transmit the data message or retransmit the first SCI message based on the feedback message.

Abstract: Aspects of the present disclosure provide techniques to reduce overhead and improve resource management by efficiently selecting RSMA spreading code for periodic traffic in IoE devices. For example, in accordance with one technique, the IoE device, during an initial access to the base station, may notify the base station of the traffic periodicity of the IoE device such that the base station may assign a spreading code from a dedicated pool that is not utilized during the periodic access of the device. Additionally or alternatively, another technique to reduce overhead and improve resource management may include the IoE devices broadcasting the selected RSMA spreading code that the IoE devices intends to use in discovery broadcasts (DBs) along with the IoE device traffic periodicity such that the IoE devices may autonomously manage selection of RSMA spreading code that avoids collisions for the same traffic periodicity.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may transmit an anchor status notification associated with a first future communication between the first wireless communication device and a second wireless communication device. The first wireless communication device may receive, using at least one set of dedicated resources, at least one announcement from at least one additional wireless communication device, wherein the at least one announcement indicates at least one second future communication associated with the at least one additional wireless communication device. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may alter, or otherwise cancel, a sidelink communication as a result of a cancelation indicator (CI) corresponding to a different UE to support automatic gain control (AGC) calibration. The UE may determine to cancel or alter sidelink resources that at least partially overlap in time and are adjacent to, yet non-overlapping, in frequency to a high priority transmission. In some implementations, the UE may cancel the sidelink communication from an earliest overlapping symbol to the end of a slot. In other implementations, the UE may cancel a portion of the sidelink communication and resume sidelink communications within the same slot. Additionally or alternatively, the UE may utilize one or more reference signals or symbols to enable AGC recalibration during the slot.

Abstract: Methods, systems, and devices for wireless communications are described. The method may involve a first user equipment (UE) receiving an indication of a set of sidelink resources and an indication of a set of uplink resources for transmitting sidelink feedback information. The first UE may receive a sidelink shared channel transmission from a second UE and upon receiving the sidelink shared transmission, generate feedback information regarding the sidelink shared channel transmission and transmit the feedback information directly to the base station using the set of uplink resources.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may transmit feedback signaling for received sidelink messages to both the base station and the transmitting UE. The receiving UE may multicast a feedback message to both the base station and the transmitting UE on a physical uplink control channel (PUCCH) or on a physical sidelink feedback channel (PSFCH). The base station may configure the receiving UE with resources, the transmitting UE may allocate resources to the receiving UE, or the base station may actively monitor for the feedback message. In some examples, the receiving UE may operate in a dual connectivity mode, and may transmit the feedback message to both the base station and the transmitting UE on both the PUCCH and the PSFCH.
