摘要： Systems and methods for generating and configuring periodization of PRS measurements. An access node receives a configuration request to configure a positioning reference signal (PRS) measurement window and determines whether to configure the measurement window in accordance with a priority associated with the PRS measurement. The access node can acknowledge the success or failure of configuring the PRS measurement window.

摘要： Systems and methods for handling multiple Angle of Arrival (AoA) solutions and their associated ambiguities are provided herein. A network node instructs for a wireless device to transmit reference signals for positioning measurements. An access node can perform positioning measurements, including measuring a plurality of AoA values for the reference signals, and report the positioning measurements accordingly.

摘要： A method, wireless device and network node are disclosed. According to one aspect, a method for a wireless device includes receiving a configuration of a reference signal resource set from the network node, the reference signal resource set being a set of single-symbol and single antenna port reference signal resources in at least one slot; and based on at least one parameter of the received configuration, determining whether the UE can assume a same antenna port for all reference signal resources of the reference signal resource set.

摘要： Methods and apparatus are provided for determining timing error groups. In one embodiment a method of operating an entity in a communications network is provided. The communications network includes a network node. The method comprising determining at least one potential margin from a predetermined plurality of potential margins. Each potential margin of the plurality of potential margins being a potential maximum margin of timing error difference between two measurements based on positioning related reference signals or transmissions of positioning related reference signals. The method further comprising transmitting an indication of the at least one potential margin to the network node. The method includes determining a margin from the at least one potential margin and performing an action. The method further comprising determining a timing error group, TEG, associated with the action based on the margin.

摘要： A communication device in a communications network receives (1710) first configuration information from a network node in the communications network. The first configuration can include an indication of a downlink, DL, positioning reference signal, PRS, resource of a plurality of DL PRS resources. The communication device can further perform (1720) at least one DL angle of departure, AOD, measurement based on the first configuration information. The communication device can further receive (1730) second configuration information from the network node. The second configuration information can include an indication of a subset of the plurality of DL PRS resources. The communication device can further report (1750) one or more DL AOD measurements.
