Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for a first user equipment (UE) to manage the reuse of resources reserved for sidelink communications by the UE. The first UE may identify scheduling information for a sidelink shared channel between the first UE and a second UE, and the first UE may reserve a set of resources for subsequent sidelink communications by the first UE. The first UE may transmit a sidelink control message indicating the scheduling information and the reserved resources to one or more neighboring UEs. The sidelink control message may include a reuse allowance indicator that may indicate whether the set of reserved resources is available for spatial reuse by the neighboring UEs. The neighboring UEs may determine whether the reuse the reserved resources based on the control message, the reuse allowance indicator, or both.

Abstract: 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: This disclosure provides systems, methods, and devices for wireless communication that support configured reception with sidelink control information (SCI) repetition over a sidelink. In aspects, a receiving user equipment (UE) may be configured to conduct combined reception/decoding of SCI repetitions (received from a transmitting UE over a sidelink) over multiple time-frequency slots at pre-defined occasions (e.g., occasions configured by a base station) to decode a sidelink transmission. In aspects, a receiving UE may receive from a transmitting UE over a sidelink, a sidelink transmission during a reception occasion that includes a plurality of reception opportunities for the receiving UE. Each reception opportunity of the plurality of reception opportunities includes a repetition of an SCI. The receiving UE decodes the SCI by combining the repetitions of the SCI received in one or more reception opportunities, and decodes a data transmission (e.g., a physical sidelink shared channel (PSSCH) transmission) using the decoded SCI.

Abstract: Methods, systems, and devices for wireless communications are described. Autonomous transmissions between a user equipment (UE) and a base station may be configured that include at least one of a modulation and coding scheme (MCS) or resources for the transmissions. In some cases, a trigger may be detected that changes the MCS or resources to be used for the autonomous transmissions. The trigger may include the presence or absence of retransmissions or the value of a channel measurement falling below or exceeding a threshold value. Accordingly, the base station and UE may adjust the MCS or resources to be used for the autonomous transmissions based on detecting the trigger and then communicate using the adjusted MCS or resources. In some cases, the configuration for the autonomous transmissions may be signaled via a medium access control (MAC) control element (CE).

Abstract: Aspects of the present disclosure provide techniques for configuring a search space for reverse sidelink communications between one or more sensors/actuators (SAs) and programmable logic controller (PLC) in internet of things (IoT) applications. Particularly, the techniques described herein configure a search space (e.g., subset of all available sub-channels) for reception of sidelink packets (e.g., physical sidelink control channel (PSCCH) and physical sidelink shared channel (PSSCH)) that may be received at the PLC from the one or more SAs. In some examples, the PLC may monitor the subset of subchannels and decode the sidelink packets received on the subset of subchannels without the need for the PLC to perform blind decoding of all sidelink sub-channels as is currently required in conventional systems. Thus, the disclosed techniques reduce latency and maximize the resource utilization (e.g., by using less processing power and bandwidth) for sidelink communications.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may transmit a polling request to a receiving device in sidelink control information that is associated with a sidelink data transmission. The polling request may be included in a sidelink control information message or in a medium access control layer message. The receiving device may respond to the polling request with an indication of whether there is data available for transmission to the transmitting device at the receiving device. The transmitting device may determine whether to schedule reverse sidelink resources for the receiving device to transmit the available data based on the response to the polling request.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may be configured to receive, from a second wireless device via a sidelink communication link, a sidelink control information (SCI) scheduling an uplink transmission from the first wireless device to the second wireless device. The first wireless device may then generate the uplink transmission based on the SCI. The first wireless device may then transit the uplink transmission to the second wireless device via the sidelink communication link in accordance with the SCI.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support physical sidelink shared channel (PSSCH) resource allocation operations. A transmit (TX) user equipment (UE) transmit a physical sidelink control channel (PSCCH) that indicates an allocated PSSCH resource portion. In a first aspect, the portion includes two non-contiguous subchannels. In a second aspect, the PSCCH indicates a layer or a node of a layer of a resource allocation layer structure. In a third aspect, the PSCCH indicates a subchannel group size for an allocated resource, using a bitmask or a value that corresponds to a subchannel and a group size combination. In a fourth aspect, the TX UE determines the portion based multiple values of subchannel and length combinations, the multiple values determined by disabling one or more combinations of a total number of subchannel and length combination for contiguous allocation, or for contiguous and non-contiguous allocation.

Abstract: Methods, systems, and devices for wireless communications are described for efficient allocation of feedback resources and transmission of feedback for low latency communications. A first user equipment (UE) may be allocated uplink resources for uplink transmissions having one or more gaps during which a second UE may transmit feedback information to initiate a retransmission within specified time limits to achieve desired quality of service (QoS) targets. The one or more gaps may be provided through a downlink control information message that indicates uplink resources to the first UE based on a first starting transmission symbol and a first length indicator, and a second starting transmission symbol and a second length indicator. The one or more gaps may be additionally or alternatively provided through one or more reserved symbols, and the first UE may skip uplink transmissions in one or more reserved symbols.

Abstract: Certain aspects of the present disclosure provide techniques for downlink relaying for passive internet of things (PIoT) communication. An example method includes receiving, from a network entity in a wireless network, configuration information for communicating with at least one passive internet of things (PIoT) device and receiving, from the network entity, a PIoT message, the PIoT message including at least a PIoT relay command instructing the UE to communicate with the at least one PIoT device. The method also includes transmitting, based on the PIoT message, one or more signals to the at least one PIoT device in accordance with the configuration information.
