Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine its position based on one or more position reference signals (PRSs), which the UE receives via different component carriers (CCs). The UE may maintain an active state with a first CC transmitting a PRS, while activating and deactivating a secondary CC that may transmit PRSs based on a periodic interval. Additionally, the UE may apply similar techniques for inactive BWPs where a PRS spans multiple BWPs. In some implementations, the position of the UE may enhance a UE mobility procedure based on determining a resource to use for the UE mobility procedure that is dependent upon the position of the UE. For example, the UE mobility procedure may include a random access procedure or a handover procedure. Additionally, the resources used for the mobility procedures may be quasi co-located with PRSs.

A method, performed in a wireless device, for obtaining position information of user equipment, UE, in a wireless communication system is described. The method includes transmitting, to a network, an indication comprising beam information defining beams that are suitable to be used for transmitting Positioning Reference Signals, PRS, to the wireless device, receiving, from the network, control signaling comprising PRS scheduling information for upcoming transmission of the PRS in beams, performing measurements on the PRS based on the PRS scheduling information that was received, and providing the measurements to the network.

This disclosure provides methods, devices, and systems for beam group reporting for positioning in new radio (NR) wireless communications systems. In some wireless communications systems, multiple PRS resources, e.g., a beam group, received by a user equipment (UE) from the same network entity may be used to produce a combined Time of Arrival (TOA) measurement for the reference or target to derive an Reference Signal Time Difference (RSTD) estimate. The UE provides to a network entity an indication of the PRS resources in the beam group, which may be specifically or generally identified. Additionally, parameters associated with the beam group are provided, such as a relative quality of the TOA measurement for each PRS resource in the subset, a spread of the TOA measurements in the subset, a relative signal strength of each PRS resource in the subset, or a spread of the signal strength in the subset.

A positioning operation for a user equipment (UE) involves a two-step process having a coarse positioning followed by a refined positioning. The coarse positioning can be based on periodic reference signals from a first set of network nodes. A refined positioning specific to the UE is configured based on the coarse positioning. The refined positioning can include targeted transmissions of reference signals to the UE by a second set of network nodes.

The present disclosure generally pertains to systems and methods for providing position information to aircraft using radio-frequency signals. By providing a ground-based solution entirely independent of GPS, systems of the present disclosure can make navigation systems more accurate and robust, enhancing their effectiveness and safety. More precisely, systems of the present disclosure may employ a series of ground-based beacon transmitters to provide coverage across a defined geographic region. Primary beacon transmitters may be used to generate a radio-frequency (RF) signal pulse with a highly regular frequency. A larger number of secondary beacon transmitters may be used to re-transmit these RF signal pulses with a tightly controlled turnaround time. A locating receiver can detect the arrival times of these pulses and use this information, along with stored information about the relative positions of the beacon transmitters, to determine its location.

Systems and methods for determining a location of one or more user equipment (UE) in a wireless system can comprise receiving reference signals via a location management unit having two or more co-located channels, wherein the two or more co-located channels are tightly synchronized with each other and utilizing the received reference signals to calculate a location of at least one UE among the one or more UE. Embodiments include multichannel synchronization with a standard deviation of less than or equal 10 ns. Embodiments can include two LMUs, with each LMU having internal synchronization, or one LMU with tightly synchronized signals.

A positioning node determines a muting configuration used by one or more base stations for controlling muting of positioning reference signals. The positioning reference signals are transmitted at recurring positioning occasions from the one or more base stations to radio equipment in a wireless communication network. The muting configuration is determined from signaling received from the one or more base stations. The positioning node sends the muting configuration information as higher-layer signaling for receipt by the radio equipment receiving the positioning reference signals. The muting configuration information includes a muting occasion parameter indicating positioning occasions to which muting applies, and each of the positioning occasions comprise two or more consecutive subframes that repeat at a predetermined periodicity.
