Abstract: Aspects relate to mechanisms for wireless communication devices to environmental sensing with the assistance of a network. A UE transmits an increase transmission power request message to a base station. The UE receives an increase transmission power acceptance message from the base station in response to transmitting the increase transmission power request message. The UE transmits a transmission using an increased transmission power for reflection by at least one object based on the increase transmission power acceptance message. The UE receives a reflection of the transmission reflected off the at least one object. The UE determines at least one parameter associated with the object based on the reflection of the transmission reflected off the at least one object.

Abstract: Aspects presented herein may enhance the configuration of the scheduling offset for communication devices within a channelized frequency band. In one aspect, a UE receives a PDCCH including a scheduling offset parameter. The PDCCH schedules one of a PDSCH for reception in a first sub-band within a BWP or provides an uplink scheduling grant of a PUSCH for transmission in a second sub-band within the BWP. The UE communicates with a base station based on one of a slot for receiving the PDSCH based on the first sub-band within the BWP and the scheduling offset parameter when the PDCCH schedules the PDSCH, or a slot for transmitting the PUSCH based on the second sub-band within the BWP and the scheduling offset parameter when a PUCCH is used to schedule the PUSCH.

Abstract: Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) transmits, to a serving base station, in one or more active bandwidth parts (BWPs) of the UE, a request for a no-downlink-scheduling gap, the request including at least time-domain parameters related to scheduling the no-downlink-scheduling gap, receives, from a neighboring base station, in the one or more active BWPs, a downlink positioning reference signal (DL-PRS) during the no-downlink-scheduling gap, and transmits, in the one or more active BWPs, an uplink positioning reference signal (UL-PRS) during the no-downlink-scheduling gap in response to reception of the DL-PRS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a restriction on a combination of frequency components permitted to be used by the UE for carrier aggregation or frequency hopping, wherein the restriction indicates at least two frequency components that are not permitted to be combined for carrier aggregation or frequency hopping. The UE may communicate based at least in part on the restriction. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that indicates a set of frequency components for carrier aggregation and that indicates multiple sets of channel state information reference signals (CSI-RSs) or sounding reference signals (SRSs), wherein different sets of CSI-RSs or SRSs, of the multiple sets of CSI-RSs or SRSs, correspond to different subsets of frequency components included in the set of frequency components. The UE may monitor for one or more CSI-RSs or SRSs, corresponding to a subset of frequency components included in the set of frequency components, based at least in part on the configuration. Numerous other aspects are provided.

Abstract: Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) receives, from a network entity, a positioning reference signal (PRS) configuration. The UE receives, from a serving base station, a measurement gap (MG) configuration. The UE determines that one or more transmission properties of one or more resources should be modified and transmits PRS modification information to the network entity based on the one or more transmission properties of one or more PRS resources to be modified. The network entity may be a location server or location management function.

Abstract: Techniques are provided for single sided beam management in a millimeter wave (mmW) communication system for use in bistatic radio frequency (RF) sensing. An example method of tracking targets with bistatic radio frequency sensing includes receiving a scanning reference signal, generating a scanning signal report indicating one or more target groups associated with the scanning reference signal, transmitting the scanning signal report, receiving tracking signal configuration information indicating a tracking reference signal associated with the one or more target groups, receiving the tracking reference signal identified in the tracking signal configuration information, and tracking the one or more target groups associated with the tracking reference signal.
