Abstract: A user equipment (UE) receives a maximum downlink (DL) Multiple-Input Multiple-Output (MIMO) layer configuration for DL communications, such as control signals or data signals, in one or more bandwidth parts (BWPs) and a positioning reference signal (PRS) configuration for receiving DL PRS. The UE receives DL PRS in an active BWP using a number of reception antennas based on, e.g., at least equal to, the maximum number of DL MIMO layers in the active bandwidth part. The UE may be configured to transmit uplink (UL) PRS, e.g., SRS for positioning purposes, using at least a maximum number of transmission antennas that is configured for communications purposes.

Abstract: Techniques are provided for time-domain processing of DL-PRS signals under certain conditions in which time-domain processing has a computational advantage over frequency-domain processing. Because of this, embodiments can provide positioning at a lower computational cost than positioning provided by traditional techniques utilizing only frequency-domain processing. This reduced computational cost can improve the battery life of mobile devices, ultimately resulting in a better user experience.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, which may be otherwise known as a user equipment (UE), may determine a capability relating to an antenna configuration associated with channel state information reporting. The UE may transmit a message including an indication of the capability, and receive a channel state information reference signal using the antenna configuration. The UE may transmit, based on the channel state information reference signal, a channel state information report in accordance with the antenna configuration associated with the channel state information reporting.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may obtain updated location information, and determine a time difference between a previous communication with a network and a scheduled uplink transmission. Based on the determined time difference, the UE may determine a timing advance (TA) component of a TA value to apply for the uplink transmission, and transmit an uplink message in the uplink transmission according to the determined TA value and the location information. In some examples, the time difference may be based on a first duration between the uplink transmission and a previous uplink transmission, a second duration between the uplink transmission and a previous TA command received from the network, or both. In some examples, the determined TA value may be based on additional parameters, such as an autonomous adjustment step, an aggregate adjustment rate, a scaling factor, or any combination thereof.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration identifying a first set of frequency resources for transmitting a sounding reference signal, where the sounding reference signal may be used at least for downlink channel state information acquisition. The UE may receive an indication of an association between the configuration for the sounding reference signal and a second set of frequency resources and determine, based on the association, values for one or more sounding reference signal transmission parameters for the first set of frequency resources. The UE may transmit the sounding reference signal on the first set of frequency resources based on the determined one or more values.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that provide managing transmissions of sidelink positioning reference signals (PRS) with a timing advance offset (TA) from a sidelink node. In aspects, a sidelink node (e.g., a target user equipment (UE) or an assisting UE) may receive transmissions from a plurality of nodes (e.g., target UEs or assisting UEs). The sidelink node obtains at least one TA to be used by a transmitting node of the plurality of nodes for transmitting a sidelink PRS to the sidelink node (e.g., to advance the sidelink PRS transmission to the sidelink node with respect to the timing of the first transmission). The TA is an offset obtained by the sidelink node based on the receiving times of the transmissions from the plurality of nodes. The sidelink node may receive PRS transmissions from the plurality of nodes in a same symbol aligned within the same CP.
