Abstract:
A method, an apparatus, and a computer program product for wireless communication are provided in connection with improving convergence to a common timing structure for devices in a distributed synchronization D2D network. In an example, a communications device is equipped to detect, by a UE, a synchronization signal during a listening slot duration scan of a communication channel. In an aspect, the listening slot duration may be defined based on a first timing structure, and the synchronization signal may be defined based on a second timing structure. The communications device may further be equipped to obtain timing information associated with the second timing structure from the synchronization signal, and determine whether the first timing structure or the second timing structure is a preferred timing structure.
Abstract:
Monostatic radar with progressive length transmission may be used with half-duplex systems or with full-duplex systems to reduce self-interference. The system transmits a first signal for a first duration and receives a first reflection of the first signal from a first object during a second duration. The system transmits a second signal for a third duration longer than the first duration and receives a second reflection of the second signal from a second object during a fourth duration. The system calculates a position of the first object and the second object based on the first reflection and the second reflection. The first signal, first duration, and second duration are configured to detect reflections from objects within a first distance of the system. The second signal, third duration, and fourth duration are configured to detect reflections from objects between the first distance and a second distance from the system.
Abstract:
A user equipment (UE) may be configured to transmit an indication of UE capability to support a cross frequency range/band sounding reference signal (SRS) indication for physical uplink shared channel (PUSCH) scheduling. The UE may transmit the indication of the UE capability to the network node, the indication of the UE capability including an association between a first reference signal (RS) transmitted in a first frequency band and a second frequency band, the second frequency band being different from the first frequency band, transmit the first RS in the first frequency band to the network node, and receive an uplink (UL) grant scheduling a UL channel associated with the second frequency band from the network node, the UL grant being based at least in part on the first RS in the first frequency band.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an integrated access and backhaul (LAB) node may receive, from a first IAB donor centralized unit (CU) via a first parent distributed unit (DU), a first indication to establish a first connection with a second parent DU associated with a second LAB donor CU. The IAB node may establish the first connection with the second parent DU. The LAB node may establish a second connection with the first IAB donor CU via the second parent DU, the first connection and the second connection forming a target path between the IAB node and the first IAB donor CU. Numerous other aspects are provided.
Abstract:
Certain aspects of the present disclosure provide techniques for a partially network-controlled repeater. A method for wireless communications by a repeater includes receiving downlink control information (DCI) from a network entity via a backhaul link, the DCI indicating a time period for beam management. The method includes performing a beam management procedure with a user equipment (UE) during the time period. The method includes determining a beam for communicating with the UE based on the beam management procedure. The method includes communicating with the UE using the beam.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, a configuration that indicates a time alignment timer associated with a timing advance group (TAG) for a bandwidth part (BWP) or a component carrier (CC) configured for multiple downlink control information (multi-DCI) based multiple transmission reception point (multi-TRP) communications. The UE may start the time alignment timer for a TRP. The UE may flush one or more hybrid automatic repeat request (HARQ) identifiers (IDs) from a HARQ buffer associated with the TRP based at least in part on an expiration of the time alignment timer. Numerous other aspects are described.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a sidelink configuration that indicates a set of sidelink slots comprising a first subset of sidelink slots to be used for first transmissions of sidelink communications and a second subset of sidelink slots to be used for second transmissions of the sidelink communications. The UE may communicate based at least in part on the sidelink configuration. Numerous other aspects are described.
Abstract:
A user equipment (UE) and related techniques are disclosed. In one aspect, the UE provides, to one or more wireless nodes of a radio access network (NG-RAN) associated with the core network or a second network entity of the core network different from the first entity, an indication of sensing directions for transmitting and receiving a radar signal to sense an environment of the apparatus. Latency may be reduced for tracking targets by skipping exhaustive scanning or complex full processing by exploiting prior sensing measurement reports collected by a sensing management function (SnMF). In this way, interference may be reduced and less resource and power usage may be enabled for sensing functions. In one case, sensing directions can be indicated in GCS and translated to a respective sensors' beam direction in LCS at NG-RAN or UE for efficient beam management. In one case, SnMF indicates a sensing direction in LCS to NG-RAN or UE for sensing signal transmission and/or reception.

Abstract:
Methods, systems, and devices for wireless communication are described. A first user equipment (UE) may monitor sidelink transmissions, during a sensing window, using multiple active receive beams in accordance with a spatial sensing configuration. The multiple active receive beams may be usable for sidelink reception, and may correspond to multiple active transmit beams that are usable for sidelink transmission. The first UE may select multiple candidate resource sets associated respectively with the multiple active receive beams based on monitoring sidelink transmissions using the multiple active receive beams. The first UE may transmit, to a second UE, using an active transmit beam of the multiple active transmit beams, a sidelink message via one or more resources selected from a candidate resource set of the multiple candidate resource sets. The candidate resource set may be associated with an active receive beam corresponding to the active transmit beam.
