Description

[Technical field]

[0001] Some example embodiments may relate generally to communications involving mobile or wireless telecommunications systems, such as Long Term Evolution (LTE) or fifth generation (5G) radio access technologies or new radio (NR) radio access technologies, or 5Gbeyond (e.g., 6G) access technologies, or other communications systems. For example, certain example embodiments may relate generally to systems and / or methods for measurement reporting. [Background technology]

[0002] Examples of mobile or wireless telecommunications systems may include Universal Mobile Telecommunications System (UMTS), Terrestrial Radio Access Network (UTRAN), Long Term Evolution (LTE) Evolved UTRAN (E-UTRAN), LTE Advanced (LTE-A), MultiFire, LTE-A Pro, and / or fifth generation (5G) radio access technology, or New Radio (NR) access technology and / or 5Gbeyond. 5G radio system refers to next generation (NG) radio systems and network architectures. 5G systems are often built based on 5G New Radio (NR), but 5G (or NG) networks can also be built based on E-UTRA radio.

[0003] NR is estimated to provide bit rates on the order of 10G to 20Gbit / s or greater and can support at least service categories such as enhanced mobile broadband (eMBB) and ultra-reliable low-latency-communication (URLLC), as well as massive machine type communication (mMTC). NR is expected to provide large-scale networking with ultra-wideband, ultra-robust low-latency connectivity to support the Internet of Things (IoT).

[0004] As IoT and machine-to-machine (M2M) communications become more prevalent, there will be an increasing need for networks that meet the needs of lower power, lower data rates, and longer battery life. The next generation radio access network (NG-RAN) represents the RAN for 5G that can deliver both NR and LTE (and LTE-Advanced).

[0005] It should be noted that in 5G, a node capable of providing radio access capabilities to user equipment (i.e., similar to Node B, NB, in UTRAN, or evolved NB, eNB, in LTE) may be referred to as Next Generation NB (gNB) if built on NR radios, and Next Generation eNB (NG-eNB) if built on E-UTRA radios. 5Gbeyond is expected to support further use cases beyond current mobile usage scenarios, such as virtual and augmented reality, artificial intelligence, instant communications, and improved support for IoT.

[Diagram 3] 1 illustrates an example flow diagram of a method according to one embodiment. [Figure 4] FIG. 1 illustrates an example of a system including multiple devices, in accordance with certain embodiments. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] It will be readily appreciated that the components of certain example embodiments as generally described herein and illustrated in the Figures may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of several example embodiments of systems, methods, apparatuses, and computer program products, e.g., for measurement reporting for downlink (DL) and / or uplink (UL) based positioning, is not intended to limit the scope of the particular embodiments, but rather represents selected example embodiments.

[0017] The features, structures, or characteristics of the exemplary embodiments described throughout this specification may be combined in any suitable manner in one or more exemplary embodiments. For example, the use of the phrase "certain embodiments," "some embodiments," or other similar expressions throughout this specification indicates that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment. Thus, the appearances of the phrases "certain embodiments," "some embodiments," "other embodiments," or other similar expressions throughout this specification do not necessarily all refer to the same group of embodiments, and the described features, structures, or characteristics may be combined in any suitable manner in one or more exemplary embodiments.

[0018] Moreover, if desired, different functions or procedures described below may be performed in different orders and / or in parallel with one another. Also, if desired, one or more of the functions or procedures described may be optional or may be combined. The following description should therefore be considered as illustrative of the principles and teachings of certain exemplary embodiments, and not as a limitation thereof.

[0019] Positioning techniques can be used to estimate the physical location of a UE. For example, the following positioning techniques can be used in NR: downlink time difference of arrival (DL-TDoA), uplink time difference of arrival (UL-TDoA), downlink angle of departure (DL-AoD), uplink angle of arrival (UL-AoA), and / or multi-cell round trip time (multi-RTT). Positioning reference signal (PRS) and sounding reference signal (SRS) can be used as reference signals to estimate the location of a UE. PRS is a reference signal for positioning in the downlink (DL). SRS is a reference signal that can be used for positioning in the uplink (UL).

[0020] In downlink positioning techniques such as DL-TDoA and DL-AoD, the UE may measure PRS from multiple gNBs. The UE may measure, for example, reference signal time difference (RSTD) and / or reference signal received power (PRS-RSRP). These measurements can then be used to assist in estimating the UE's location. The UE may report these measurements to a location management function (LMF). In downlink and uplink positioning techniques, the UE may measure the time difference between the reception time of the PRS and the transmission time of the SRS. The UE may report these measurements to the LMF.

[0021] Certain embodiments may relate to NR positioning. Third Generation Partnership Project (3GPP) Release 16 includes native positioning support in NR. For example, some example embodiments may relate to enhancements to DL or DL+UL UE-assisted positioning solutions. In particular, some example embodiments may relate to enhancements to UE-assisted positioning solutions.

[0022] Release 17 considers NR positioning enhancements such as specifying methods, measurements, signaling, and / or procedures to improve the positioning accuracy of Release 16 NR positioning methods by mitigating UE receive (Rx) / transmit (Tx) and / or gNB Rx / Tx timing delays, including DL, UL, and DL+UL positioning methods and / or UE-based and UE-assisted positioning solutions. Additionally, procedures, measurements, reporting, and signaling are considered to improve the accuracy of UL AoA for network-based positioning solutions and / or DL-AoD for UE-based and network-based (including UE-assisted) positioning solutions. As part of the DL-AoD enhancements, reporting of Positioning Reference Signal (PRS) Reference Signal Received Path Power (RSRPP) for the first path of a particular PRS resource is expected to be supported.

[0023] For both UE-based and UE-assisted DL-AoD, the UE may be required to measure and report (in the UE-assisted case) the PRS reference signal received power (RSRP) of the first path depending on the UE capabilities. The measurement path DL PRS RSRP of the i-th path delay may be defined as the power of the received DL PRS signal configured for measurement at the i-th path delay of the channel response.

[0024] In addition, the path DL PRS RSRP of the first path delay may be the power corresponding to the first detected path. Note that the UE may choose to use a time window to calculate the path DL PRS RSRP depending on the UE implementation. Also, the UE may report the time delay information of the first path.

[0025] However, the definition of the PRS RSRPP remains unclear. For example, the PRS RSRPP may be defined as a path RSRP per resource element (RE) in the same way that the PRS RSRP is defined as a power per RE.

[0026] Another remaining issue concerns reporting of the PRS RSRPP of the first path in DL-AoD. This new reporting feature for per-path RSRP is not only for DL-AoD. For UL Sounding Reference Signal (SRS) resources too, the gNB can report the RSRP of the first path based on the following agreement:

[0027] For example, in the case of a first arriving path measurement for an SRS for a positioning resource, the gNB may report the following set of measurements to the LMF: {one SRS-RSRP, multiple UL-AOAs (AoA / ZoA pairs), one UL-RTOA}, {one SRS-RSRP, multiple UL-AOAs (AoA / ZoA pairs), one gNB Rx-Tx time difference}, or {multiple SRS-RSRPs, multiple UL-AOAs (AoA / ZoA pairs), one UL-RTOA, one gNB Rx-Tx time difference}.

[0028] For first arriving path measurements for SRS on MIMO resources, the gNB may report the following set of measurements to the LMF: {one SRS-RSRP, multiple UL-AOA (AoA / ZoA pairs), one UL-RTOA}, or {multiple SRS-RSRPs, multiple UL-AOA (AoA / ZoA pairs), one UL-RTOS}. These gNB measurements may be associated with an SRS resource ID and timestamp, which may also be reported to the LMF. Note that the operation of the SRS for multiple-input multiple-output (MIMO) is transparent to the UE.

[0029] In case of multi-RTT and DL-TDOA, the UE may report the path RSRP of the first path and the additional path. For example, the UE may report the path RSRP of the first path and the additional path as part of DL-TDOA, UL-TDOA and multi-RTT reporting enhancements. Additionally, there may be support for introducing a request from the LMF to the UE / TRP when it is desired that the path RSRP of the additional path be reported, and / or support for the path RSRP of the additional path as part of DL-AoD.

[0030] As outlined above, the PRS RSRPP measurements may be defined as absolute values ​​and the current absolute and differential reporting mapping table may be reused for this purpose, however, a reference measurement needs to be determined when the differential reporting function is applied.

[0031] Therefore, the UE can report the first path PRS RSRPP as an absolute value for a specific PRS resource, and the parameters for absolute value reporting are captured as provisional values ​​in higher layer signaling. This can be a reasonable option to reduce the report signaling overhead and can work if there is no ambiguity from the LMF side.

[0032] However, even if a certain PRS resource among multiple PRS resources shows the maximum value of the first path PRS RSRPP, this does not guarantee that the transmit beam direction of this PRS resource is in the line of sight (LoS) direction. That is, the maximum first path PRS RSRPP of a PRS resource does not guarantee that the shortest path power is the maximum. The ratio of the first path PRS RSRPP to the total power may constitute important information. If the UE reports the PRS RSRPP of only the first path, there is still ambiguity from the LMF side.

[0033] Furthermore, DL-AoD currently does not support PRS RSRPP reporting for additional paths. If the LMF only knows the path power of the first path and does not know the path power of any additional paths, the LMF may not be able to properly determine whether the "first path" is acceptable for use for DL-AoD calculations.

[0034] Certain embodiments may address this issue at least by, for example, ensuring that the LMF has knowledge of the percentage of power coming from the first path. Although DL-TDoA and multi-RTT technologies support RSRPP reporting of the first and additional paths, the LMF cannot expect the UE to report RSRPP and / or PRS RSRP of all paths, since the reporting is up to the UE implementation and the LMF cannot indicate to the UE to report PRS RSRP and / or PRS RSRPP.

[0035] One solution may be for NR positioning to restrict the UE to report PRS RSRPP along with total PRS RSRP; it is expected that the PRS RSRPP reporting only option will also be accepted. Even if differential reporting functionality is supported, the same problem may occur unless additional restrictions are placed on differential reporting. For example, a UE may or may not be enabled to report PRS RSRPP for the same resource. Thus, certain embodiments provide systems, devices and / or methods that overcome at least the problems and challenges discussed above, as well as other problems or challenges that may not be explicitly mentioned herein.

[0036] As described in further detail below, certain embodiments may include LFM and / or UE behavior when the UE reports only the PRS RSRPP for multiple PRS resources. Note that as used herein, a UE in this disclosure may also be referred to as a user device, and vice versa.

[0037] Further, it should be understood that a UE or user device is not limited to cellular or mobile phones, but may include any electronic device that may or may not include a transceiver for wireless communication, etc. For example, this may include, but is not limited to, a computer, a laptop, a headset, a vehicle, a camera, a sensor, or any other suitable device that may or may not be described herein.

[0038] Figure 1 illustrates an example signaling flow diagram 100 according to one embodiment. As shown in Figure 1, the signaling flow diagram 100 may include messages or information sent to and / or received from, for example, a gNB, a UE, and / or an LMF. However, it should be noted that this is only an example and the signaling may involve other network elements or network nodes.

[0039] According to one embodiment, the LMF and / or the gNB may provide the UE with positioning assistance information including at least a PRS resource configuration. As shown in the example of FIG. 1, at 105, the gNB may transmit a periodic DL RS (e.g., a PRS) to the UE.

[0040] As further shown in the example of Figure 1, the LMF may initiate DL-AoD, DL-TDOA and / or multi-RTT positioning for the UE at 110. The UE may then report DL PRS RSRPP of a first path of multiple PRS resources to the LMF at 115, where the UE reports a specific timestamp along with DL PRS RSRPP measurements for these multiple PRS resources, where the timestamp indicates when the UE obtained these DL PRS RSRPP measurements. The reporting at 115 may be done using, for example, differential reporting or absolute value reporting.

[0041] In a particular embodiment, the LMF may use the reported PRS RSRPP for multiple PRS resources in a PRS resource set or a subset of PRS resources to estimate the location of the target UE.

[0042] According to one embodiment, the LMF can determine whether it needs to obtain additional information regarding the (total) PRS RSRP for each PRS resource. For example, the LMF may determine that a previous report of the PRS RSRP is not valid for the UE, and therefore the LMF needs to obtain another update and / or the LMF needs to check whether the first path is the dominant path.

[0043] Thus, in one embodiment, the LMF may request the UE to report a (total) PRS RSRP for a set of PRS resources corresponding to a reported PRS RSRPP that the UE previously obtained at a particular timestamp in 120. According to some embodiments, this timestamp may be the reported timestamp from the UE when the UE reports a DL PRS RSRPP for the set of PRS resources in 115.

[0044] 1, the UE may check its buffered data and its movement at 125. According to some embodiments, the UE may receive a transmission of a periodic DL RS (e.g., PRS) at 130.

[0045] In one embodiment, as shown at 135, if the UE has not buffered or stored the PRS RSRP (e.g., total PRS RSRP) for the PRS resources for which the UE reported the first-path PRS RSRPP, or if the UE has not measured the PRS RSRP (e.g., total PRS RSRP) for the reported PRS resources at a time corresponding to the indicated timestamp and the UE has not moved compared to the particular indicated timestamp, the UE may measure the PRS RSRP (e.g., total PRS RSRP) for the requested PRS resources using the Rx beam and Rx branch used at the indicated timestamp. According to this embodiment, at 135, the UE may report the same timestamp as the particular indicated timestamp. In this case, the UE does not need to additionally measure and report the first-path PRS RSRPP.

[0046] In a further embodiment, if the UE has not buffered or stored PRS RSRPs (e.g., total PRS RSRPs) for the PRS resources for which the UE reported a PRS RSRPP of the first path, or if the UE has not measured the PRS RSRPs (e.g., total PRS RSRPs) for the reported PRS resources at a time corresponding to the particular indicated timestamp, and if the UE has moved beyond a threshold compared to the indicated timestamp, the UE may report both new PRS RSRPs and PRS RSRPPs for the PRS resources previously reported by the UE. In this case, the UE may report a new timestamp that is different from the indicated timestamp.

[0047] According to certain embodiments, as shown in example 140 of FIG. 1, if the UE has buffered or stored PRS RSRPs (e.g., total PRS RSRPs) for the PRS resources for which the UE reported a PRS RSRPP for the first path, and if the UE has not moved compared to the indicated timestamp, the UE may report a requested PRS RSRP for that set of PRS resources and may include the same timestamp as the indicated timestamp.

[0048] In some embodiments, if the UE has not buffered or stored a PRS RSRP (e.g., total PRS) for the PRS resources for which the UE reported a PRS RSRPP of the first path, and if the UE has not moved for a certain duration (t ∈ {t0, t1, t2}, where t0≦t1≦t2), the UE may indicate a timestamp of a previously reported PRS RSRP (t1) that is the same as the PRS RSRP at the indicated timestamp.

[0049] Note that the previously reported PRS RSRP may include timestamp t0. In this case, the timestamp of the previously reported measurement {RSRP, timestamp:t0} for the set of PRS resources is effectively replaced by t1. According to this embodiment, the UE does not need to report all PRS RSRP measurements for the requested PRS resources.

[0050] According to a particular embodiment, if the UE has buffered or stored PRS RSRPs (e.g., total PRS RSRPs) for PRS resources for which the UE reported a PRS RSRPP of the first path, and if the UE has moved beyond a threshold compared to the indicated timestamp, the UE may report both new PRS RSRPs and PRS RSRPPs for PRS resources previously reported by the UE. In this embodiment, the UE may report a new timestamp that is different from the indicated timestamp.

[0051] In one embodiment, if the UE has not buffered or stored the PRS RSRPs (e.g., total PRS RSRPs) for the PRS resources for which it has reported the PRS RSRPPs of the first path, or if the UE has not measured the total PRS RSRPs for the reported PRS resources at the time corresponding to the indicated timestamp, the UE may inform the LMF that it is unable to comply with the indication / request from the LMF, as shown at 145 in the example of FIG. 1 .

[0052] According to some embodiments, the UE may delete any buffered measurement data at 150. As also shown in the example of FIG. 1, the LMF may re-estimate the location of the target UE at 155 using the reported measurements.

[0053] In one embodiment, the LMF may configure one or more thresholds for when the UE should report the RSRP along with the RSRPP. For example, the LMF may indicate that if the RSRPP is less than or equal to X% of the total power (RSRP), the UE should include both the PRS RSRPP and the PRS RSRP for the PRS resource in the initial measurement report.

[0054] Similarly, the LMF may request the UE to exclude the PRS RSRP when the UE reports the PRS RSRPP of the first path for PRS resources if the PRS RSRPP is dominant.

[0055] According to a particular embodiment, the buffering capability may vary depending on the capability of the UE. The UE may report its measurement buffering capability to the LMF so that the LMF can take it into account for a measurement report request / indication.

[0056] As another embodiment, two types of received power values ​​are specified for DL ​​PRS RSRPP. One power value is legacy PRS RSRP and another power value is PRS RSRPP. As an option, if the UE can measure or report only one measurement of PRS RSRP and PRS RSRPP, the LMF can indicate via pre-configuration which of PRS RSRP or PRS RSRPP needs to be measured and reported. For example, the LMF can provide an RSRP type indicator to indicate whether PRS RSRP and / or PRS RSRPP needs to be measured and reported. Thus, the UE can receive a request and / or an indication to report one measurement of PRS RSRP and RSRPP or both PRS RSRP and PRS RSRPP.

[0057] In some embodiments, all or some of the UE behaviors described above may be configured or indicated by the gNB and / or the LMF.

[0058] An example flow diagram of a method for positioning according to one example embodiment is shown in Figure 2. For example, Figure 2 may show an example method for positioning-based DL and / or UL measurement reporting according to some embodiments.

[0059] In certain example embodiments, the flow diagram of FIG. 2 may be performed by a network entity or communication device (or group of entities or devices) in a communication system, such as, but not limited to, LTE, 5G NR, or 5Gbeyond. For example, in some example embodiments, the communication device performing the method of FIG. 2 may include a UE, a sidelink (SL) UE, a user device, a wireless device, a mobile station, an IoT device, a UE-based roadside unit (RSU), a wireless transmit / receive unit, a customer premises equipment (CPE), a laptop, a headset, a vehicle, a sensor, other mobile or fixed devices, etc. For example, in certain example embodiments, the method of FIG. 2 may include procedures or operations performed by a UE as described or illustrated elsewhere herein, such as in FIG. 1.

[0060] 2, the method may include, at 205, receiving a first request, for example, from a network node. For example, the network node may be, or may include, a location management node, an LMF, or other node responsible for location management services.

[0061] In some example embodiments, the first request may indicate to the user device to report a PRS RSRP for a set of PRS resources corresponding to a previous report that indicated a PRS RSRPP of the user device previously obtained at a first timestamp, e.g., using a particular Rx beam and Rx branch. For example, in some example embodiments, the first request may correspond to or be similar to the request received by the UE at 120 in the example of FIG.

[0062] According to certain example embodiments, the method of Figure 2 may include transmitting a second report to the network node at 210 based on the at least one status of the user device. For example, in some example embodiments, the second report may correspond to or be similar to one or more of the reports transmitted by the UE at 135, 140 or 145 of the example of Figure 1. In one embodiment, the at least one status of the user device may include at least one of a buffered data status and / or a mobility status.

[0063] According to certain embodiments, the second report based on at least one status of the user device may include one or more of: reporting a measured PRS RSRP using the same Rx beam and Rx branch used for measuring the PRS RSRPP when the user device has no buffered data and is not moving, reporting a PRS RSRP and a first timestamp corresponding to the previous report when the user device has buffered data and is not moving, and / or reporting an indicator indicating that there is no valid measured PRS RSRP when the user device is moving.

[0064] In one embodiment, the method or transmitting 210 may include reporting, by the user device, a PRS RSRPP for the set of PRS resources of the first timestamp. According to one embodiment, the method or receiving 205 may include receiving, by the user device, one or more thresholds that may indicate reporting an RSRP with the PRS RSRPP.

[0065] In one embodiment, the one or more thresholds may include or indicate a percentage of an RSRPP (power) threshold, in which case reporting may include the user device indicating both a PRS RSRPP and a PRS RSRP for the set of PRS resources when the RSRPP is not greater than the percentage of the RSRP threshold.

[0066] In some embodiments, the method or receiving 205 may include receiving, by the user device, a request from the network node to exclude the PRS RSRP when the user device reports the PRS RSRPP for the set of PRS resources if the PRS RSRPP is dominant.

[0067] According to an embodiment, the method or transmitting 210 may include transmitting, by the user device, the measurement buffering capabilities to a network node.

[0068] It should be noted that Figure 2 is provided as an example of a method or process according to certain embodiments, however, certain modifications, variations, or adjustments to the process of Figure 2 are possible according to further embodiments, as may be described elsewhere herein.

[0069] An example flow diagram of a method for positioning according to an example embodiment is shown in Figure 3. For example, Figure 3 may show an example method of DL and / or UL measurement reporting based on positioning according to some embodiments.

[0070] In certain example embodiments, the flow diagram of Figure 3 may be performed by a network entity or communication device in a communication system, such as, but not limited to, LTE, 5G NR, or 5Gbeyond. For example, in some example embodiments, a communication device performing the method of Figure 3 may include a location management entity or LMF. For example, in some embodiments, the method of Figure 3 may include procedures or operations performed by an LMF as described or illustrated elsewhere herein, such as in Figure 1.

[0071] As shown in the example of Figure 3, the method may include transmitting a first request to the user device at 305. In some example embodiments, the first request may indicate to the user device to report a PRS RSPP for a set of PRS resources corresponding to a previous report that indicated a PRS RSRPP of the user device previously obtained at a first timestamp, e.g., using a particular Rx beam and Rx branch. For example, in some example embodiments, the first request may correspond to or be similar to the request transmitted by the LMF at 120 in the example of Figure 1.

[0072] According to one embodiment, the method of Figure 3 may include receiving a second report based on at least one status of the user device at 310. For example, in some example embodiments, the second report may correspond to or be similar to one or more of the reports received by the LMF at 135, 140 or 145 of the example of Figure 1. In one embodiment, the at least one status of the user device may include at least one of a buffered data status and / or a movement status.

[0073] According to certain example embodiments, the second report based on at least one status of the user device may include one or more of: a measured PRS RSRP using the same Rx beam and Rx branch used to measure the PRS RSRPP when the user device has no buffered data and is not moving, a PRS RSRP and first timestamp corresponding to the previous report when the user device has buffered data and is not moving, and / or an indicator indicating that there is no valid measured PRS RSRP when the user device is moving.

[0074] In some example embodiments, the method of FIG. 3 may include, at 315, estimating a location of the user device based on the PRS RSRP for the set of PRS resources reported in the second report.

[0075] According to a particular embodiment, the method or receiving 310 may include receiving a PRS RSRPP for the set of PRS resources at the first timestamp from the user device.

[0076] In some example embodiments, the method or transmitting 305 may include transmitting one or more thresholds to the user device. The one or more thresholds may indicate reporting the RSRP along with the PRS RSRPP. In one embodiment, the one or more thresholds may include or indicate a percentage of an RSRP (power) threshold. In this case, if the RSRPP is not greater than the percentage of the RSRP threshold, the method or receiving 310 may include receiving an indication of both the PRS RSRPP and the PRS RSRP of the PRS resources from the user device.

By way of example, the apparatus 10 may be implemented as, for example, a wireless handheld device, a wireless plug-in accessory, or the like. It should be noted that one skilled in the art would recognize that the apparatus 10 may include components or features not shown in FIG. 4 .

[0081] As shown in the example of FIG. 4, the device 10 may include a processor 12 for processing information and executing instructions or operations. The processor 12 may be any type of general-purpose or special-purpose processor. In fact, the processor 12 may include, by way of example, one or more of a general-purpose computer, a special-purpose computer, a microprocessor, a digital signal processor (DSP), a field programmable gate array (FPGA), an application specific integrated circuit (ASIC), and a processor based on a multi-core processor architecture. Although a single processor 12 is shown in FIG. 4, multiple processors may be used according to other embodiments. For example, it should be understood that in certain embodiments, the device 10 may include two or more processors that may form a multiprocessor system that may support multiprocessing (e.g., in this case, the processor 12 may represent a multiprocessor). In certain embodiments, the multiprocessor system may be tightly or loosely coupled (e.g., to form a computer cluster).

[0082] Processor 12 may perform functions associated with the operation of device 10, including precoding antenna gain / phase parameters, encoding and decoding individual bits forming communication messages, formatting information, and overall control of device 10, including processes related to management of communication resources. In certain embodiments, processor 12 may be configured as a processing or control means for performing any of the procedures described herein.

[0083] The apparatus 10 may further include or be coupled to a memory 14 (internal or external) couplable to the processor 12 for storing information and instructions executable by the processor 12. The memory 14 may be one or more memories and may be of any type suitable for the local application environment and may be implemented using any suitable volatile or non-volatile data storage technology, such as semiconductor-based memory devices, magnetic memory devices and systems, optical memory devices and systems, fixed memory, and / or removable memory.

For example, the external computer-readable storage medium may store computer programs or software for execution by processor 12 and / or device 10.

[0087] In some embodiments, device 10 may also include or be coupled to one or more antennas 15 for transmitting signals and / or data to device 10 and for receiving signals and / or data from device 10.

As a further example, the term "circuitry" as used herein may also cover implementations of only a hardware circuit or processor (or processors), or portions of a hardware circuit or processor, and its associated software and / or firmware. The term circuitry also covers baseband integrated circuits in a server, a cellular network node or device, or other computing or network device.

In some example embodiments, the first request can indicate to the device 10 to report a PRS RSRP for a set of PRS resources corresponding to a previous report that indicated a PRS RSRPP of the device 10 previously obtained at a first timestamp. For example, in some embodiments, the first request can correspond to or be similar to the request received by the UE at 120 in the example of FIG. 1.

[0097] According to certain example embodiments, the transceiver 18 can be configured to transmit to the network node a second report based on the at least one status of the device 10. For example, in some example embodiments, the second report may correspond to or be similar to one or more of the reports transmitted by the UE at 135, 140 or 145 in the example of Figure 1. In one embodiment, the at least one status of the device 10 may include at least one of a buffered data status and / or a mobility status.

[0098] According to certain embodiments, the second report based on at least one status of device 10 may include one or more of: reporting a measured PRS RSRP using the same Rx beam and Rx branch used to measure the PRS RSRPP when device 10 has no buffered data and is not moving, reporting a PRS RSRP and a first timestamp corresponding to the previous report when device 10 has buffered data and is not moving, and / or reporting an indicator indicating that there is no valid measured PRS RSRP when device 10 is moving.

[0099] In one embodiment, the transceiver 18 is configurable to report to the network node a PRS RSRPP for the set of PRS resources at the first timestamp. According to one embodiment, the transceiver 18 is configurable to receive from the network node one or more thresholds that may indicate reporting an RSRP along with the PRS RSRPP. In one embodiment, the one or more thresholds may include or indicate a percentage of an RSRP (power) threshold. In this case, when the RSRPP is not greater than the percentage of the RSRP threshold, the transceiver 18 is configurable to report or indicate to the network node both the PRS RSRPP and the PRS RSRP for the set of PRS resources.

[0100] In some embodiments, the transceiver 18 can be configured to receive a request from the network node to exclude a PRS RSRP when the device 10 reports a PRS RSRPP for a set of PRS resources if the PRS RSRPP dominates. According to one embodiment, the transceiver 18 can be configured to transmit the measurement buffering capabilities to the network node.
