Description

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application claims priority US Provisional Application No. 62 / 403,400 (P109989Z), filed October 3, 2016. This application no. 62 / 403.400 is fully incorporated herein by reference.

GENERAL PRIOR ART

In Narrowband Internet of Things (NB-IoT), the uplink positioning signal is transmitted on a very narrow band which reduces the received signal quality at the developed Node B (eNB), which in turn can affect the positioning accuracy. The narrowband uplink positioning signal is sensitive to the interference and fading channel as compared to the standard user equipment (UE) uplink positioning signal, which operates according to a Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) standard. Furthermore, the eNB need not configure the uplink positioning signal for the destination UE for the Uplink Time Difference of Arrival (UTDOA), that is, the eNB may itself decide how to configure the uplink positioning signal. In the case of the NB-IoT, however, such an arrangement can lead to problems in positioning accuracy.

In the Technical Specification (TS) 36.305 for 3GPP, the local measurement units (LMUs) should know the characteristics of the Sounding Reference Signal (SRS) sent by the UE for the period in which the uplink measurement is to be computed to be uplinked. Receive measurements for uplink positioning. These properties should be static via the periodic transmission of SRS signals during uplink measurements. Therefore, the Evolved Serving Mobile Location Center (E-SMLC) indicates to the server eNB to instruct the UE to transmit SRS signals for uplink positioning. It is up to the eNB to make the final decision about resources to allocate and to transmit this configuration information back to the -SMLC so that the E-SMLC can configure the LMUs. The eNB may decide not to configure resources for the UE and to report the empty resource configuration to the E-SMLC, such as in a case where resources are not available. NB IoT terminals are being used more and more often in the current market, for example in the form of portable smart devices, and the positioning requirements for these devices are becoming increasingly important. Thus, it would be advantageous to improve up-to-date uplink positioning accuracy and reduce interference.

DETAILED DESCRIPTION

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the claimed content. However, it will be understood by one of ordinary skill in the art that the claimed content may be embodied in these specific details. In other cases, known methods, procedures, Components, and / or circuits are not described in detail.

With reference to 1 For example, a diagram of uplink positioning according to one or more embodiments will be discussed. The network 100 as in 1 can have multiple developed Node B (eNB) devices such as eNB1 110 , eNB2 112 and eNB3 114 etc. and one or more user equipment (UE) devices such as UE1 116 , UE2 118 , and UE3 120 , and so on. In one or more embodiments, one or more eNBs may have corresponding local measurement units (LMUs), such as LMU1 122 , LMU2 124 and LMU3 126 and so on.

There are several types of LMUs for uplink positioning. One type is: an LMU integrated into an eNB. In such an arrangement, the eNB and the LMU are in the same location. Such as in 1 is the eNB1 110 the server eNB of the destination positioning UE (UE1) 116 , eNB2 112 is the server eNB for UE2 118 and eNB3 114 is the server eNB for UE3 120 , LMU1 122 is in eNB 1110 integrated, LMU2 124 is in eNB2 112 integrated and LMU3 126 is in eNB3 114 integrated. UE1 116 may be configured to position an uplink positioning signal for uplink positioning on a particular time frequency resource, and eNB2 may also be used during the same time period 112 and eNB3 114 the uplink transmission for their own respective UEs, UE2 118 and UE3 120 , configure. network 100 can also have a positioning server 128 that is about a SLmAP in communication with the LMUs included, and the eNBs of network 100 could continue via a Mobility Management Entity (MME) 130 via a LPPa in communication with the positioning server 128 although the scope of the claimed content is not limited in this regard.

In order to obtain a position of the target positioning UE, the target positioning UE transmits an uplink positioning signal for obtaining positioning measurements for the target positioning UE to the LMUs. The LMUs then provide the positioning measurements to the positioning server 128 ready. During the measurement process, the receiver receives the LMU2 124 a strong signal from the UE2 118 that is a disturbance of the uplink positioning signal from UE1 116 could be. As a result, the performance of LMU2 124 be affected in the measurement of the uplink positioning signal from the UE1. A similar situation can be found for LMU3 114 occur when the uplink positioning signal from UE1 116 is measured, with a signal from UE3 120 the performance of LMU3 126 in the measurement of the uplink positioning signal from UE1 116 can affect. As a result, the uplink positioning accuracy could be very low. According to one or more embodiments, the different approaches may be implemented to reduce such interference from other UEs when the uplink positioning signal from the target positioning UE via attenuation information or via a configuration of the uplink positioning signal from the target positioning UE generated by the UE positioning server 128 may be distributed to the struck eNBs to attenuate or configure the uplink time frequency resource used by the target positioning UE and / or one or more of the other UEs.

With reference to 2 FIG. 10 is a diagram of an uplink positioning method, according to one or more embodiments, in which suppression information is to indicate that the scheduling or configuration of an uplink signal on a specified time frequency resource used by a destination user equipment (UE) is discussed. In a first embodiment, a positioning server 128 an information request to the server eNB, eNB1 110 , to indicate to the server eNB that it has an uplink positioning signal for the destination positioning UE, UE1 116 should configure. Additional information can be used in this information request to indicate that the configuration is mandatory. The server eNB may configure the uplink positioning signal for the destination positioning UE. The server eNB can send the configuration information back to the positioning server. The positioning server then sends the measurement request to all affected LMUs with the uplink positioning signal configuration information, and the positioning server distributes the attenuation information to all neighboring eNBs involved because the involved LMUs are integrated into these neighboring eNBs. The neighbor eNBs attenuate their respective UEs on the uplink time frequency resource used by the destination positioning UE for the uplink positioning signal.

To implement this embodiment, as in 1 shown, the positioning server sends 128 an information request message 210 using an LTE Positioning Protocol A (LPPa) Protocol Data Unit (PDU) in a transaction that is for the server eNB, eNB1 110 , Instructions indicates an uplink positioning signal for the destination positioning UE, UE1 116 to call. In this information request message 210 , an indication A is used to indicate that it is a mandatory configuration case. This indication A is sent to require the server eNB to configure the UL positioning signal for the destination positioning UE. After the server eNB receives this indication A, the server eNB may provide the UL positioning signal for the server Configure target positioning UE. Next, the server eNB determines the resources associated with the destination positioning UE and sends an information response message 212 to the positioning server (E-SMLC) containing the associated resources and associated parameters via an LPPa PDU. The server eNB then allocates the resources to the destination positioning UE and configures the destination positioning UE with UL Positioning Radio Resource Control (RRC) resources.

The positioning server (E-SMLC) 128 chooses a set of LMUs, such as LMU 122 , LMU 124 and LMU 126 to use the uplink positioning operation and sends a measurement request message 214 via a selective assignment (SLm) protocol with the UL positioning signal configuration to each of the LMUs. The positioning server 128 also sends an LPPa PDU message 216 Attenuation information or UL positioning signal configuration of the target positioning UE to the neighboring eNBs, such as the eNB2 112 and eNB 114 that contain LMUs for this positioning operation. Attenuation information is intended to indicate that the scheduling or configuration uplink signal is not allowed on the specific time frequency resource used by the destination positioning UE. After the receiver of the one or more neighboring eNBs has this attenuation information or UL positioning signal configuration of the target positioning UE, the neighboring eNBs do not schedule or configure uplink signal transmission from that time frequency resource used by the target positioning UE. The LMUs then report to the positioning server (E-SMLC) 128 the uplink metering reports returned by the LMUs via the SLM log message 218 were obtained.

With reference to 3 "A diagram of a method for uplink positioning according to one or more embodiments wherein a scrambling sequence is used by a destination user equipment (UE) and other different scrambling sequences used by other UEs will be discussed. In a second embodiment, a positioning server sends 128 an information request to the server eNB to indicate to the server eNB that it should configure an uplink positioning signal for the destination positioning UE. Additional information can be used in this information request to indicate that the configuration is mandatory. The server eNB configures uplink positioning signal for the destination positioning UE with a particular scramble sequence. The server eNB sends the configuration information and the scramble sequence information back to the positioning server 128 , The positioning server 128 then sends the measurement request to all affected LMUs with the uplink positioning signal configuration information, and the positioning server 128 then distributes the uplink signal configuration information to all participating neighbor eNBs having involved LMUs integrated into these neighboring eNBs. The neighbor eNBs then configure a specific scramble sequence for their respective UEs, which will soon send an uplink signal on the same time frequency resource used by the destination positioning UE. This specific scramble sequence is different from that used by the target positioning UE, and the correlation level of these two scramble sequences can be very small to avoid signal interference.

To implement such an embodiment, the positioning server (E-SMLC) sends 128 an information request message 310 via an LPPa PDU, the server eNB, eNB1 110 , indicates that an uplink positioning signal for the destination positioning UE, UE1 116 must be called. In this information request message 310 , an indication A can be used to indicate that it is a mandatory configuration case. This indication A may be sent to require the server eNB to configure the UL positioning signal for the destination positioning UE. After the server eNB receives this indication A, the server eNB will configure the UL positioning signal for the destination positioning UE.

The server eNB, eNB 110 , configures uplink positioning signal for the destination positioning UE, UE1 116 , with a specific scramble sequence. This scramble sequence is for the purpose of avoiding interference. The server eNB then sends an informational response message 312 via an LPPa PDU to the positioning server (E-SMLC) 128 including the configuration information for the UL positioning signal of the target positioning UE, including which time frequency resource is used and which scramble sequence is used by the target positioning UE, and which scramble sequence is used by and other UEs. The server eNB then allocates the resources of the destination positioning UE with a specific scramble sequence, such as to the positioning server 128 reported.

The positioning server 128 chooses a set of LMUs, such as LMU1 122 , LMU2 124 and LMU3 126 to use the uplink positioning operation and sends a measurement request message 314 via an SLm protocol with the UL positioning signal configuration to each of the selected LMUs from the set. The positioning server 128 sends a UL positioning signal configuration message 316 over an LPPa PDU having configuration information of the target positioning UE to one or more neighboring eNBs, such as eNB2 112 and eNB3 114 in which the selected LMUs are integrated for this positioning operation. The UL positioning signal configuration of the target positioning UE includes the information of the time frequency resource used for this UL positioning signal and the scramble sequence configuration. After the one or more neighboring eNBs receive this UL positioning signal configuration from the destination positioning UE, the one or more neighboring eNBs configure a specific scramble sequence for their own respective UEs, which will soon transmit the uplink signal on the same time frequency resource which is used by the target positioning UE. The specific scramble sequence for the UEs of one or more of the adjacent eNBs is different from the specific scramble sequence used by the target positioning UE. The correlation level of these two different scramble sequences can be very low to avoid signal interference. The selected LMUs receive the uplink signal measurements from the target positioning UE and then report the uplink measurement reports via SLm protocol message 318 back to the positioning server.
