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: A first apparatus may be configured to generate a scheduling request to request to transmit at least one of data or control information on a sidelink channel. The first apparatus may be further configured to transmit, to another UE, the scheduling request on resources of a channel configured to carry feedback responsive to transmissions on the sidelink channel. A second apparatus may be configured to monitor resources on a channel for transmissions from other UE, the channel being configured to carry feedback from the other UE responsive to transmissions on a sidelink channel. The second apparatus may be further configured to receive at least one scheduling request from at least one of the other UE on the resources of the channel configured to carry the feedback based on monitoring the resources on the channel.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform blind decoding, for sidelink control information (SCI) in resources in one or more sub-channels of a sidelink resource pool, based at least in part on an aggregation level or a resource aggregation configuration. The UE may receive the SCI based at least in part on performing the blind decoding for the SCI. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described.

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: Systems and methods for implementing semi-persistent scheduling (SPS) transmission of periodic messages via one or more sidelinks are described.

SPS control signaling utilized for activating/deactivating SPS for a sidelink groupcast may include a SPS indicator (e.g., conveyed at least in part via SCI format 0-1 message), an activation/deactivation indicator (e.g., conveyed at least in part via SCI format 0-1 message and/or SCI format 0-2 message), and/or a configuration index (e.g., conveyed at least in part via SCI format 0-1 message and/or SCI format 0-2 message). Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may send coupled configured grants to a transmitter user equipment (UE) and a receiver UE, respectively. For example, when transmitting a pair of configured grants that includes a first configured grant sent to a first UE and a second configured grant sent to a second UE, the base station may include an indication in each of the configured grants that sidelink semi-persistent scheduling resources are activated or deactivated. Additionally, the configured grants may indicate which UE is a receiver and which UE is a transmitter. For instance, the first configured grant may indicate that a first UE is to be the transmitter and a second configured grant indicate that a second UE is to be the receiver.

A first user equipment (UE) may receive, from a base station associated with the first UE and a second UE, a downlink control information activating a set of configured grant resources for transmissions from the second UE to the first UE. The UE may transmit, according to the downlink control information, a feedback message to the base station confirming receipt of the downlink control information.

Abstract: Aspects of the present disclosure provide techniques for configuring a search space for sidelink communications between a plurality of user equipments (UEs).

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may determine a first set of resources for communications over a sidelink communication link between the first UE and a second UE. The first UE may transmit, to the second UE via the sidelink communication link, a first sidelink control information including a reverse sidelink scheduling indicator based on determining the first set of resources. The first UE may additionally transmit, to the second UE via the sidelink communication link, a second sidelink control information indicating a second set of resources for reverse sidelink transmissions from the second UE to the first UE over the sidelink communication link, where transmitting the second sidelink control information is based on transmitting the first sidelink control information. The first UE may receive, from the second UE, a reverse sidelink message in response to transmitting the second sidelink control information.

Abstract: Methods, systems, and devices for wireless communications are described for improving sidelink communication reliability. In some examples, a user equipment (UE) may map allocated sidelink resources from a logical domain to a physical domain, where the mapped resources may include greater frequency diversity in the physical domain. A frequency range of a sidelink control channel or of a sidelink data channel may be greater in the physical domain than in the logical domain after the mapping. In some examples, sidelink communications may be associated with an aggregation factor that represents a number of repetitions of a sidelink communication. In this example, a UE may repeat a sidelink communication within a contention-based resource pool a number of times before receiving feedback in order to increase communication reliability. A first UE may communicate a sidelink communication with a second UE using a resource mapping or repetitions of the sidelink communication.

Abstract: Systems and non-transitory computer-readable mediums for scheduling resources for a specific sidelink are described. Some embodiments provide scheduling of resources for a sidelink between a first user equipment (UE) in communication with a base station and a specified second UE in communication with the first UE, such as using downlink control information (DCI) and/or radio resource control (RRC) signaling. The scheduling of sidelink resources may be with respect to a dynamic grant (DG) or a configured grant (CG). Other aspects and features are also claimed and described.
