In one aspect, an apparatus transmits, to a second UE, an indication to provide HARQ feedback for at least one sidelink channel. The apparatus transmits, to the second UE, the at least one sidelink channel.

Abstract: Methods, systems, and devices for wireless communications are described. Aspects of the present disclosure provide a user equipment (UE) with a capability to identify an enhanced sidelink resource pool including resources that are otherwise excluded from configured sidelink resource pools. In some examples, the UE may identify the enhanced sidelink resource pool based on sidelink parameters for transmitting one or more sidelink messages, and the UE may use the enhanced sidelink resource pool for additional sidelink transmissions. The additional sidelink transmissions may include standalone sidelink control information (SCI) transmissions or other types of transmissions associated with sidelink communications. The resources associated with the enhanced sidelink resource pool may have a relatively finer granularity than those included within a base sidelink resource pool that is, for example, configured by a network.

Abstract: A technique is disclosed for generating class level rules that globally explain the behavior of a machine learning model, such as a model that has been used to solve a classification problem. Each class level rule represents a logical conditional statement that, when the statement holds true for one or more instances of a particular class, predicts that the respective instances are members of the particular class. Collectively, these rules represent the pattern followed by the machine learning model. The techniques are model agnostic, and explain model behavior in a relatively easy to understand manner by outputting a set of logical rules that can be readily parsed. Although the techniques can be applied to any number of applications, in some embodiments, the techniques are suitable for interpreting models that perform the task of classification. Other machine learning model applications can equally benefit.

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. In some wireless communications networks, a first wireless device may transmit sidelink control information to a second wireless device, which includes a first scheduling for an uplink transmission by a second wireless device during a first slot. The second wireless device may decode the sidelink control information to determine an operating mode of the first wireless device during the first slot, such as a transmitting mode or a receiving mode.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform single frequency network (SFN) manner relaying in sidelink to support exchanging packets between UEs, for example, without maintaining beamforming alignment between the UEs. A first UE (e.g., a source UE or destination UE) may establish a pre-agreement with a second UE for the second UE to operate as an SFN-manner relay over sidelink for the first UE. The pre-agreement may be reached via a publish-and-subscription procedure, in which the second UE publishes an SFN-type relaying service and the first UE subscribes to the SFN-type relaying service. The second UE may receive sidelink signaling associated with the first UE (e.g., transmitted by or to the first UE) and may relay the sidelink signaling in a resource configured for SFN-type transmission based on the first UE being subscribed to the SFN-type relaying service.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may utilize opportunistic cooperative relaying to support exchanging packets between UEs without establishing or maintaining beamforming alignment between the UEs. Specifically, a source UE may invite nearby UEs (e.g., helper UEs) that receive a sidelink transmission (e.g., a packet meant for a different destination UE) to perform a single frequency network (SFN)-type transmission to opportunistically relay the packet to the destination UE. The helper UEs may receive, decode, and transmit the sidelink signaling from the source UE without establishing or configuring a relay agreement with the source UE. The destination UE may receive the sidelink signaling via cascading, SFN-type transmissions by one or more helper UEs. The destination UE may respond to the sidelink signaling with feedback information via one or more helper UEs or directly to the source UE.

The SCI may include information associated with a sidelink data transmission from the second UE to the first UE. Numerous other aspects are provided.
