Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured with a set of parameters to determine a valid timing advance (TA) to transmit data using preconfigured uplink resources (PUR) during an idle or inactive mode. In some cases, the parameters are one or more TA commands and one or more conditions associated with each TA command. The UE may identify the current condition of the UE and determine whether the current condition of the UE matches one of indicated conditions. The UE may select a TA command based on finding a match and use the TA command to transmit an uplink PUR transmission. Additionally or alternatively, the parameters may be neural network parameters that indicate a neural network model that the UE may use to determine a TA command associated with a valid TA based on the current condition of the UE.

Abstract: A protocol stack architecture for processing machine learning (ML) data includes a ML layer to manage ML data communication with a network device. The ML layer is coupled to multiple ML training blocks, and ML and inference blocks for multiple neural networks, and an analog data communications stack coupled to the ML layer. The analog data communications stack has an upper media access control analog (MAC-A) layer coupled to the ML layer and configured to store data for each neural network, a lower MAC-A layer coupled to the upper MAC-A layer and configured to segment and reassemble analog ML data, and an analog physical layer coupled to the lower MAC-A layer and configured to communicate analog data with the network device. The architecture includes a digital data communications stack coupled to the ML layer and the lower MAC-A layer and configured to manage digital communications with the network device.

Abstract: The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. In one aspect, the apparatus may measure one or more candidate bandwidths, each of the one or more candidate bandwidths corresponding to a candidate channel. The apparatus may also select an operating bandwidth of the one or more candidate bandwidths based on the measured one or more candidate bandwidths, the operating bandwidth corresponding to an operating channel. Additionally, the apparatus may adjust an energy detection threshold of a reference bandwidth based on a sensing bandwidth. The apparatus may also determine whether a transmission medium is available based on at least one of the adjusted energy detection threshold or an interference level of at least one signal.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support a velocity estimation, such as a velocity estimation with radio frequency (RF) sensing. In a first aspect, a velocity of an object is determined based on doppler measurements from multiple transmission/reception points (TRPs). In a second aspect, the velocity of the object is determined based on angle of arrival (AoA) information received from multiple TRPs. The AoA information may include a range, an AoA, a time, or a combination thereof. In a third aspect, the velocity of the object is determined based on an orientation of the object during a sensing operation performed by a TRP. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may identify, for an initial slot of a periodic interval, a number of symbols included in the initial slot and a length of cyclic prefixes used for the symbols included in the initial slot based on a subcarrier spacing that is configured for wireless communication. The length of a first set of cyclic prefixes may be based on a length of a cyclic prefix calculated for an initial symbol of the initial slot at the configured subcarrier spacing. The wireless device may perform communications based on the determined number of symbols and length of cyclic prefixes included in the initial slot. Performing communications may include allocating resources based on a length of the cyclic prefixes used for the symbols included in the initial slot.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a network entity, such as a location server, may determine information characterizing a channel associated with a wireless device within a region of interest. The network entity may determine a location of the wireless device within the region of interest based on that information and a set of radio frequency fingerprints (RFFPs), where each RFFP identifies a geographic location within a region of interest and a channel condition at that geographic location within the region of interest, and where each geographic location within the region of interest is represented by a set of RFFPs having different channel conditions due to different states of at least one reconfigurable intelligent surface (RIS) within the region of interest.

Abstract: Some techniques and apparatuses described herein may be used to avoid or reduce collisions between uplink data communications and uplink control communications for an enhanced machine-type communication user equipment (eMTC UE) operating in an unlicensed radio frequency spectrum band. Furthermore, some techniques and apparatuses may avoid such collision while still allowing efficient use of resources, such as by deferring the uplink data communication within a data segment, rate matching an uplink data communication around uplink control resources (e.g., cell-specific uplink control resources and/or UE-specific uplink control resources), puncturing the uplink data communication to avoid the uplink control resources, multiplexing uplink control information on an uplink data channel, and/or the like.

Abstract: Positioning of a user equipment (UE) is supported using reception points (RPs) that receive uplink sounding reference signals (SRS) from the UE. The RPs may measure signal strengths of received SRS that are used to determine path loss reference values that are provided to the UE for configurating subsequent SRS. The UE may report a plurality of RxTx time difference measurements with respect to a single PRS for the SRS transmitted to a plurality of RPs. The RPs may provide an Rx time for received SRS, which is used to generate a RxTx time different measurement for asymmetric round trip time (RTT) if the RP and TRP clocks are synchronized. The RPs may provide an RxRx time difference measurement for a time of reception of PRS and SRS if the RP and TRP clocks are synchronized. A location server determines a position of the UE using different positioning measurements.

Abstract: Methods, systems, and devices for wireless communications are described. To support a reliable array response for wideband communications, a base station may configure a set of transmission instances for a set of signals distributed across a wideband carrier bandwidth. At least one transmission instance of the set of transmission instances may be configured in each sub-band of the carrier bandwidth. The base station may transmit the set of signals in the configured transmission instances to a user equipment (UE). The UE may receive the set of signals distributed across the carrier bandwidth and may measure, for the signals, a set of signal measurements corresponding to the set of sub-bands. Based on the signal measurements, the UE may determine a set of communication beams for the set of sub-bands. Using one or more of the determined communication beams, the UE may communicate with the base station in the carrier bandwidth.
