    Abstract: Disclosed are techniques for wireless communication. In an aspect, a position estimation entity, obtains first timing information that is associated with a first time-of-arrival (TOA) measurement of a first reference signal for positioning (RS-P) as communicated between a target user equipment (UE) and a base station with a first time basis, obtains second timing information that is associated with a second TOA measurement of a second RS-P as communicated between the target UE and a reference UE associated with a known location and having a second time basis that is different than the first time basis, determines a bias between the first time basis and the second time basis, and determines a position estimate of the target UE via a time differential of arrival (TDOA) positioning technique based at least in part upon the first timing information, the second timing information, and the bias.

    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.

    IPC: H04W72/12

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to one or more other UEs in a group of wireless network devices that includes the first UE and the one or more other UEs, an indication that the UE is a current sidelink scheduler for the UEs in the group of wireless network devices. The UE may receive, from at least one other UE in the group of wireless network devices, a scheduling request for a sidelink communication to be transmitted by the at least one other UE. The UE may transmit, to the at least one other UE, a grant of resources for the sidelink communication to be transmitted by the at least one other UE. Numerous other aspects are described.

    Abstract: Apparatus, methods, and computer-readable media for facilitating indicating cancelation of transmissions of sidelink messages are disclosed herein. An example method for wireless communication at a sidelink device includes transmitting SCI reserving a set of resources for one or more retransmissions of a message, the set of resources identifying one or more reserved resources in a time domain. The example method also includes identifying a skipped transmission associated with one or more of the set of resources reserved by the sidelink device. Additionally, the example method includes transmitting a cancelation indication indicating the skipped transmission, the cancelation indication indicating that the skipped transmission corresponds to a previous reserved resource in the time domain, a current reserved resource in the time domain, or a future reserved resource in the time domain.
