Abstract: In an aspect of the disclosure, a method, a computer program product, and an apparatus are provided. The apparatus may be a first node. The first node determines a data frame based on synchronization information. The data frame has a signaling block and a plurality of data slots. The signaling block is prior to the plurality of data slots. The first node communicates with a second node in the signaling block to reserve a first data slot of the plurality of data slots during which to transmit or to receive a first packet. The first node transmits the first packet to the second node or receives the first packet from the second node during the first data slot.

Abstract: Systems and techniques are provided for accelerated ray tracing. For instance, a process can include obtaining a hierarchical acceleration data structure that includes a plurality of primitives of a scene object and obtaining a respective information value associated with each primitive included in the plurality of primitives. A sort order can be determined for two or more nodes included in a same level of the hierarchical acceleration data structure at least in part by sorting the two or more nodes based on a respective sorting parameter value determined for each respective node of the two or more nodes. Each respective sorting parameter value can be determined based on at least one information value associated with one or more primitives included in a sub-tree of each respective node of the two or more nodes. The hierarchical acceleration data structure can be traversed using the sort order.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network entity may receive, from a second network entity, an indication of a first frequency offset associated with the second network entity. In some aspects, the first network entity may receive, from the second network entity, a first transmission including a first communication and a first helper signal that are separated in a frequency domain based on the first frequency offset. In some aspects, the first network entity may decode, via envelope tracking, the first transmission to obtain the first communication from the first transmission. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide techniques that may help enhance power control for sidelink transmissions. According to certain aspects, a method for wireless communications by a first user equipment (UE) generally includes transmitting a power headroom report (PHR) to a second UE, receiving, from the second UE, a transmit power control (TPC) based on the PHR, and transmitting at least a first sidelink transmission to the second UE with transmit power in accordance with the TPC.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support the transmission of a scheduling request via a physical sidelink feedback channel (PSFCH). In some cases, a user equipment (UE) may determine a configuration of a set of PSFCH resource blocks (RBs). The UE may receive a first bit map that may indicate a subset of the set of PSFCH RBs allocated for transmitting a scheduling request on the PSFCH, and the UE may receive a second bit map that may indicate a second subset of the PSFCH RBs allocated for hybrid automatic repeat request (HARQ) messages. The UE may transmit a scheduling request via one or more RBs of the first subset of the PSFCH RBs. In some cases, the UE may generate a waveform for transmitting the scheduling request message, and the waveform may be based on the number of RBs selected.

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).
