摘要： A method, network node and wireless device for position reference signal (PRS) design by extending a base signal are disclosed. According to one aspect, a method in a wireless device (WD) includes obtaining extended reference signal, RS, configurations from the network node. The method also includes determining a waveform associated with the extended RS. The method also includes detecting a RS and estimate an associated time of arrival. The method further includes sending a measurement report to the network node based on the estimated time of arrival.

摘要： A method (2200) by a first network node (560) includes transmitting (2202), to a second network node (560), a message comprising search window information, The search window information includes information associated with an expected angle and information associated with an uncertainty level of the expected angle. The first network node receives (2204) a response message from the second network node. The response message comprises feedback associated with a use of the search window information by the second network node.

摘要： A wireless device and a method therein for receiving positioning system information from a radio network node. The wireless device and the radio network node operate in a wireless communications network. The wireless device receives positioning system information broadcast scheduling information comprising information about positioning System Information Blocks that are comprised in a System Information message. Further, the wireless device receives an indication that a pSIB is segmented into pSIB segments. Based on the indication and on the pSI the wireless device determines whether or not the pSIB segments are scheduled via contiguous scheduling. When the pSIB segments are determined to be scheduled via contiguous scheduling, the wireless device monitors scheduled resources, retrieves the contiguously scheduled pSIB segments and decodes position system information of the retrieved pSIB segments.

摘要： A method performed by a target device to obtain positioning assistance data from a location server is provided. The target device and the location server are operating in a wireless communications network. The target device transmits a request to the location server. The request is a request for positioning assistance data and provides first logical position information. The target device obtains positioning assistance data from the location server. The positioning assistance data is based on the first logical position information. When being associated with a second logical position, the target device transmits a request to the location server. The request requests for positioning assistance data and provides second logical position information. The target device obtains positioning assistance data from the location server. The positioning assistance data is based on the second logical position information.

摘要： A method for positioning reference signal configuration comprises receiving, from a network node, one or more first positioning reference signals in a first PRS configuration; performing one or more first measurements on the first PRS to determine one or more first characteristics of the one or more first PRSs; sending, to the network node, a second PRS configuration determined based on the one or more first characteristics; receiving, from the network node, a third PRS configuration, wherein the third PRS configuration comprises one or more third PRSs having at least one different signal characteristic than the one or more first characteristics of the first PRS; and performing one or more second measurements on the one or more third PRSs. The method provides a dynamic configuration for PRS based on the feedback from the UE and a location node, beamforming configuration, or any requirements for physical layer efficiently.
