Description

USER EQUIPMENT POSITIONING MEASUREMENT PERIOD FOR NEW RADIO SYSTEMS
CROSS REFERENCE TO RELATED APPLICATIONS
The present application claims priority to U.S. Provisional Patent Application No. 63/065,397, which was filed August 13, 2020 and U.S. Provisional Patent Application No. 63/066,768, which was filed August 17, 2020.
FIELD
Various embodiments generally may relate to the field of wireless communications. For example, some embodiments may relate to user equipment (UE) measurement delays for new radio (NR) position measurement.
BACKGROUND
In previous RAN4 meetings, the manner in which to define the reporting table for NR positioning measurement was discussed. Particularly from a user equipment (UE) implementation perspective, when considering the measurement period, some complexity aspects should be accounted. Typically, there are a number of implementation aspects which need to be taken into account, for example, reference signal time difference (RSTD) measurements cannot be processed in real time, thus some limited buffering of data and correlation results is needed. Furthermore, as discussed in the context of an LI measurement period for the RSTD, it should be set so that it allows UE to do the measurements and calculations also in serial manner, rather than requiring all the cells being processed simultaneously to alleviate the processing and memory consumption requirements. Embodiments of the present disclosure address these and other issues.

DETAILED DESCRIPTION
The following detailed description refers to the accompanying drawings. The same reference numbers may be used in different drawings to identify the same or similar elements. In the following description, for purposes of explanation and not limitation, specific details are set forth such as particular structures, architectures, interfaces, techniques, etc. in order to provide a thorough understanding of the various aspects of various embodiments. However, it will be apparent to those skilled in the art having the benefit of the present disclosure that the various aspects of the various embodiments may be practiced in other examples that depart from these specific details. In certain instances, descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the various embodiments with unnecessary detail. For the purposes of the present document, the phrases “A or B” and “A/B” mean (A), (B), or (A and B).
In a previous RANI meeting, UE capability for PRS processing and buffering was agreed as [R1 -2002770]:
Proposal 1
• For the purpose of DL PRS processing capability, the duration of DL PRS symbols (K) in ms within any P msec window, is calculated by o Type 1 duration calculation with o Type 2 duration calculation with o where
■ Type 1 or Type 2 is reported as UE capability,
■ S is the set of slots of a serving cell within the P msec window in the positioning frequency layer that contains potential DL PRS resources considering the actual nr-DL-PRS-ExpectedRSTD, nr-DL-PRS- ExpectedRSTD-Uncertainty provided for each pair of DL PRS Resource Sets (target and reference).
■ for Type l,[Ts start, Ts end] is smallest interval in ms within slots corresponding to an integer number of OFDM symbols of a serving cell that covers the union of the potential PRS symbols and determines the PRS symbol occupancy within slots.
• Interval [Ts start, Ts end] considers the actual nr-DL-PRS- ExpectedRSTD, nr-DL-PRS-ExpectedRSTD-Uncertainty provided for each pair of DL PRS Resource Sets (target and reference).
As the UE’s capability for positioning reference signal (PRS) processing depends on the definition of duration (e.g., Typel and Type2) below, the measurement delay requirements can be defined regarding to type duration calculation. o Type 1 duration calculation with:
- o Type 2 duration calculation with:
Therefore, in some embodiments it may be concluded that the necessary measurement period (or delay) may depend on:
1. How many PRS occasions are scheduled by the network. The available PRS depends on the PRS periodicity and the measurement gap period jointly.
Tavaiable_PRS = LCM (TPP&, M GRP) (1)
2. UE processing capability
The basic/minimum UE processing time unit is ”T”.
The UE processing time for all PRS slots within a PRS occasion is Tproc. The basic processing time for UE is “T” which is indicated by UE capability (N, T)
Regarding to the impact due to UE processing capability of (N , T), in some embodiments the measurement period may be enlarged when the duration of total PRS resources within a PRS occasion (denoted by “LPRS”) is longer than N. Hence the exact scaling factor because of (N , T) can be represented as
Moreover, as the additional UE processing capability depending on a shorter measurement window (per slot) was defined as N', the measurement time for PRS symbols within a slot will be extended if the duration of total PRS symbols within a slot (denoted by NpRs) is out of UE’s reported capability N’. That is, if the total measurement duration needed for NPRs PRS resource is less than N' which indicated by the other UE PRS processing capability, the measurement period for LPRS resource can rely on UE capability (N,T) only.
Nslot
Otherwise the measurement period shall be scaled by also as illustrated in Figure 1 below.
However, if there is additional UE buffering capability limitation, Tproc is the UE processing time per an valid sample in which PRS resource(occupied in ”N” duration) are included. On the other hand depending on the UE’s capability ”N” which inidicate the maximum buffer size of UE and NW configuaiton on the PRS resource size ”Lprs” we can discuss the following two cases:
• Case A: Lprs<= N
UE can buffer all PRS resource within one PRS occassion in a ’’Tproc”
Then regarding UE processing capbility limition (e.g. the processing time ’’Tproc” is larger than Tavaiable PRS or not), o Case A- 1 (Figure 2): Tproc <= Tavaiable PRS o Case A-2 (Figure 3): Tproc > Tavaiable PRS
The measurement time for all PRS symbols (Lprs) can be
• Case B: Lprs> N (Figure 4)
TUE need buffer one PRS occassion resource in succesive avaialble PRS gaps. o In Case B, the total samples needed for a PRS session measurement shall be scaled by ” [^] " o Tproc in this case is the UE processing time per a valid sample which can occupied Lprs.
Type equation here.
Thus the interval between the two adjacent samples can be:
Generally all cases can be formulated by Eq (6) indeed.
If there are Nsamples PRS occasions to be measured for one positioning session, the total delay for this PRS measurement session can be
Beyond the discussion on the basic measurement period per a PRS layer, more open issues shall be considered below.
1 ) Whether or how to extend the measurement period to account for Rx beam sweeping in FR2
Moreover, in the last meeting it was discussed whether or how to extend the measurement period to account for Rx beam sweeping in FR2. In our view, UE behaviour to support the PRS measurement in case of RX beam sweeping can be similar to that of S SBbased RRM. Therefore, embodiments of this disclosure may propose:
Observation 7: The scaling factor for PRS measurement delay due to RX beam sweeping can be the same as that of an SSB-based RRM measurement in R15.
2) Measurement period for more than one frequency layer
If a UE needs to be able to perform the measurement on the multiple positioning frequency layer at the same time, the processing complexity and memory consumption can easily become multiple of the number of layers to be considered, unless some limitations are set. As RANI agreed “UE capability for simultaneous DL PRS processing across positioning frequency layers is not supported in Rel.16”, the total measurement delay on the multiple positioning frequency layer shall be sum of each layer measurement duration totally.
The RSTD measurement delay can be defined as:
Wherein:
• i is the index of PRS positioning frequency measurement layer
• PRS layer zv tbe number of positioning frequency layers
• KpRsjixBeam zv tbe scaling factor for FR2 RX beam sweeping, o If QCL information is known by UE and the associated reference signal (e.g. SSB) is detectable, XpnsjixBeam can be 1. Otherwise it is [8] for UE supporting FR2 power class 1 and [24/5] for UE supporting FR2 power class 2/3/4
For ith positioning frequency layer o T PRSi zv tbe PRX resource set periodicity o PRS resource duration within a PRS resource occasion is denoted by a j "
LPRS ,i o PRS symbol duration per a slot is denoted by “Npgs i" o UE DL PRS processing capability is indicated by {Nt Ti and {Ni '} defined in TS38.214
• Nsamples is the number of PRS occasions to be measured per a positioning session
• CSSFRSTD,! is the scaling factor for the RSTD measurements on the “i”th positioning frequency layer
SYSTEMS AND IMPLEMENTATIONS
Figures 5-6 illustrate various systems, devices, and components that may implement aspects of disclosed embodiments.
Figure 5 illustrates a network 500 in accordance with various embodiments. The network 500 may operate in a manner consistent with 3GPP technical specifications for LTE or 5G/NR systems. However, the example embodiments are not limited in this regard and the described embodiments may apply to other networks that benefit from the principles described herein, such as future 3GPP systems, or the like.
The network 500 may include a UE 502, which may include any mobile or non-mobile computing device designed to communicate with a RAN 504 via an over-the-air connection. The UE 502 may be communicatively coupled with the RAN 504 by a Uu interface. The UE 502 may be, but is not limited to, a smartphone, tablet computer, wearable computer device, desktop computer, laptop computer, in-vehicle infotainment, in-car entertainment device, instrument cluster, head-up display device, onboard diagnostic device, dashtop mobile equipment, mobile data terminal, electronic engine management system, electronic/engine control unit, electronic/engine control module, embedded system, sensor, microcontroller, control module, engine management system, networked appliance, machine-type communication device, M2M or D2D device, loT device, etc.
In some embodiments, the network 500 may include a plurality of UEs coupled directly with one another via a sidelink interface. The UEs may be M2M/D2D devices that communicate using physical sidelink channels such as, but not limited to, PSBCH, PSDCH, PSSCH, PSCCH, PSFCH, etc.
In some embodiments, the UE 502 may additionally communicate with an AP 506 via an over-the-air connection. The AP 506 may manage a WLAN connection, which may serve to offload some/all network traffic from the RAN 504. The connection between the UE 502 and the AP 506 may be consistent with any IEEE 802.11 protocol, wherein the AP 506 could be a wireless fidelity (Wi-Fi®) router. In some embodiments, the UE 502, RAN 504, and AP 506 may utilize cellular-WLAN aggregation (for example, LWA/LWIP). Cellular-WLAN aggregation may involve the UE 502 being configured by the RAN 504 to utilize both cellular radio resources and WLAN resources.
The RAN 504 may include one or more access nodes, for example, AN 508. AN 508 may terminate air-interface protocols for the UE 502 by providing access stratum protocols including RRC, PDCP, RLC, MAC, and LI protocols. In this manner, the AN 508 may enable data/voice connectivity between CN 520 and the UE 502. In some embodiments, the AN 508 may be implemented in a discrete device or as one or more software entities running on server computers as part of, for example, a virtual network, which may be referred to as a CRAN or virtual baseband unit pool. The AN 508 be referred to as a BS, gNB, RAN node, eNB, ng-eNB, NodeB, RSU, TRxP, TRP, etc. The AN 508 may be a macrocell base station or a low power base station for providing femtocells, picocells or other like cells having smaller coverage areas, smaller user capacity, or higher bandwidth compared to macrocells.
In embodiments in which the RAN 504 includes a plurality of ANs, they may be coupled with one another via an X2 interface (if the RAN 504 is an LTE RAN) or an Xn interface (if the RAN 504 is a 5G RAN). The X2/Xn interfaces, which may be separated into control/user plane interfaces in some embodiments, may allow the ANs to communicate information related to handovers, data/context transfers, mobility, load management, interference coordination, etc.
The ANs of the RAN 504 may each manage one or more cells, cell groups, component carriers, etc. to provide the UE 502 with an air interface for network access. The UE 502 may be simultaneously connected with a plurality of cells provided by the same or different ANs of the RAN 504. For example, the UE 502 and RAN 504 may use carrier aggregation to allow the UE 502 to connect with a plurality of component carriers, each corresponding to a Pcell or Scell. In dual connectivity scenarios, a first AN may be a master node that provides an MCG and a second AN may be secondary node that provides an SCG. The first/second ANs may be any combination of eNB, gNB, ng-eNB, etc.
The RAN 504 may provide the air interface over a licensed spectrum or an unlicensed spectrum. To operate in the unlicensed spectrum, the nodes may use LAA, eLAA, and/or feLAA mechanisms based on CA technology with PCells/Scells. Prior to accessing the unlicensed spectrum, the nodes may perform medium/carrier-sensing operations based on, for example, a listen-before-talk (LBT) protocol.
In V2X scenarios the UE 502 or AN 508 may be or act as a RSU, which may refer to any transportation infrastructure entity used for V2X communications. An RSU may be implemented in or by a suitable AN or a stationary (or relatively stationary) UE. An RSU implemented in or by: a UE may be referred to as a “UE-type RSU”; an eNB may be referred to as an “eNB-type RSU”; a gNB may be referred to as a “gNB-type RSU”; and the like. In one example, an RSU is a computing device coupled with radio frequency circuitry located on a roadside that provides connectivity support to passing vehicle UEs. The RSU may also include internal data storage circuitry to store intersection map geometry, traffic statistics, media, as well as applications/software to sense and control ongoing vehicular and pedestrian traffic. The RSU may provide very low latency communications required for high speed events, such as crash avoidance, traffic warnings, and the like. Additionally or alternatively, the RSU may provide other cellular/WLAN communications services. The components of the RSU may be packaged in a weatherproof enclosure suitable for outdoor installation, and may include a network interface controller to provide a wired connection (e.g., Ethernet) to a traffic signal controller or a backhaul network.
In some embodiments, the RAN 504 may be an LTE RAN 510 with eNBs, for example, eNB 512. The LTE RAN 510 may provide an LTE air interface with the following characteristics: SCS of 15 kHz; CP-OFDM waveform for DL and SC-FDMA waveform for UL; turbo codes for data and TBCC for control; etc. The LTE air interface may rely on CSI- RS for CSI acquisition and beam management; PDSCH/PDCCH DMRS for PDSCH/PDCCH demodulation; and CRS for cell search and initial acquisition, channel quality measurements, and channel estimation for coherent demodulation/detection at the UE. The LTE air interface may operating on sub-6 GHz bands.
In some embodiments, the RAN 504 may be an NG-RAN 514 with gNBs, for example, gNB 516, or ng-eNBs, for example, ng-eNB 518. The gNB 516 may connect with 5G-enabled UEs using a 5G NR interface. The gNB 516 may connect with a 5G core through an NG interface, which may include an N2 interface or an N3 interface. The ng-eNB 518 may also connect with the 5G core through an NG interface, but may connect with a UE via an LTE air interface. The gNB 516 and the ng-eNB 518 may connect with each other over an Xn interface.
In some embodiments, the NG interface may be split into two parts, an NG user plane (NG-U) interface, which carries traffic data between the nodes of the NG-RAN 514 and a UPF 548 (e.g., N3 interface), and an NG control plane (NG-C) interface, which is a signaling interface between the nodes of the NG-RAN514 and an AMF 544 (e.g., N2 interface).
The NG-RAN 514 may provide a 5G-NR air interface with the following characteristics: variable SCS; CP-OFDM for DL, CP-OFDM and DFT-s-OFDM for UL; polar, repetition, simplex, and Reed-Muller codes for control and LDPC for data. The 5G-NR air interface may rely on CSI-RS, PDSCH/PDCCH DMRS similar to the LTE air interface. The 5G-NR air interface may not use a CRS, but may use PBCH DMRS for PBCH demodulation; PTRS for phase tracking for PDSCH; and tracking reference signal for time tracking. The 5G- NR air interface may operating on FR1 bands that include sub-6 GHz bands or FR2 bands that include bands from 24.25 GHz to 52.6 GHz. The 5G-NR air interface may include an SSB that is an area of a downlink resource grid that includes PSS/SSS/PBCH.
In some embodiments, the 5G-NR air interface may utilize BWPs for various purposes. For example, BWP can be used for dynamic adaptation of the SCS. For example, the UE 502 can be configured with multiple BWPs where each BWP configuration has a different SCS. When a BWP change is indicated to the UE 502, the SCS of the transmission is changed as well. Another use case example of BWP is related to power saving. In particular, multiple BWPs can be configured for the UE 502 with different amount of frequency resources (for example, PRBs) to support data transmission under different traffic loading scenarios. A BWP containing a smaller number of PRBs can be used for data transmission with small traffic load while allowing power saving at the UE 502 and in some cases at the gNB 516. A BWP containing a larger number of PRBs can be used for scenarios with higher traffic load.
The RAN 504 is communicatively coupled to CN 520 that includes network elements to provide various functions to support data and telecommunications services to customers/subscribers (for example, users of UE 502). The components of the CN 520 may be implemented in one physical node or separate physical nodes. In some embodiments, NFV may be utilized to virtualize any or all of the functions provided by the network elements of the CN 520 onto physical compute/storage resources in servers, switches, etc. A logical instantiation of the CN 520 may be referred to as a network slice, and a logical instantiation of a portion of the CN 520 may be referred to as a network sub-slice.
In some embodiments, the CN 520 may be an LTE CN 522, which may also be referred to as an EPC. The LTE CN 522 may include MME 524, SGW 526, SGSN 528, HSS 530, PGW 532, and PCRF 534 coupled with one another over interfaces (or “reference points”) as shown. Functions of the elements of the LTE CN 522 may be briefly introduced as follows.
The MME 524 may implement mobility management functions to track a current location of the UE 502 to facilitate paging, bearer activation/deactivation, handovers, gateway selection, authentication, etc.
The SGW 526 may terminate an SI interface toward the RAN and route data packets between the RAN and the LTE CN 522. The SGW 526 may be a local mobility anchor point for inter-RAN node handovers and also may provide an anchor for inter-3GPP mobility. Other responsibilities may include lawful intercept, charging, and some policy enforcement.
The SGSN 528 may track a location of the UE 502 and perform security functions and access control. In addition, the SGSN 528 may perform inter-EPC node signaling for mobility between different RAT networks; PDN and S-GW selection as specified by MME 524; MME selection for handovers; etc. The S3 reference point between the MME 524 and the SGSN 528 may enable user and bearer information exchange for inter-3GPP access network mobility in idle/active states.
The HSS 530 may include a database for network users, including subscription-related information to support the network entities’ handling of communication sessions. The HSS 530 can provide support for routing/roaming, authentication, authorization, naming/addressing resolution, location dependencies, etc. An S6a reference point between the HSS 530 and the MME 524 may enable transfer of subscription and authentication data for authenticating/ authorizing user access to the LTE CN 520.
The PGW 532 may terminate an SGi interface toward a data network (DN) 536 that may include an application/content server 538. The PGW 532 may route data packets between the LTE CN 522 and the data network 536. The PGW 532 may be coupled with the SGW 526 by an S5 reference point to facilitate user plane tunneling and tunnel management. The PGW 532 may further include a node for policy enforcement and charging data collection (for example, PCEF). Additionally, the SGi reference point between the PGW 532 and the data network 5 36 may be an operator external public, a private PDN, or an intra-operator packet data network, for example, for provision of IMS services. The PGW 532 may be coupled with a PCRF 534 via a Gx reference point.
The PCRF 534 is the policy and charging control element of the LTE CN 522. The PCRF 534 may be communicatively coupled to the app/content server 538 to determine appropriate QoS and charging parameters for service flows. The PCRF 532 may provision associated rules into a PCEF (via Gx reference point) with appropriate TFT and QCI.
In some embodiments, the CN 520 may be a 5GC 540. The 5GC 540 may include an AUSF 542, AMF 544, SMF 546, UPF 548, NSSF 550, NEF 552, NRF 554, PCF 556, UDM 558, and AF 560 coupled with one another over interfaces (or “reference points”) as shown. Functions of the elements of the 5GC 540 may be briefly introduced as follows.
The AUSF 542 may store data for authentication of UE 502 and handle authentication- related functionality. The AUSF 542 may facilitate a common authentication framework for various access types. In addition to communicating with other elements of the 5GC 540 over reference points as shown, the AUSF 542 may exhibit an Nausf service-based interface.
The AMF 544 may allow other functions of the 5GC 540 to communicate with the UE 502 and the RAN 504 and to subscribe to notifications about mobility events with respect to the UE 502. The AMF 544 may be responsible for registration management (for example, for registering UE 502), connection management, reachability management, mobility management, lawful interception of AMF-related events, and access authentication and authorization. The AMF 544 may provide transport for SM messages between the UE 502 and the SMF 546, and act as a transparent proxy for routing SM messages. AMF 544 may also provide transport for SMS messages between UE 502 and an SMSF. AMF 544 may interact with the AUSF 542 and the UE 502 to perform various security anchor and context management functions. Furthermore, AMF 544 may be a termination point of a RAN CP interface, which may include or be an N2 reference point between the RAN 504 and the AMF 544; and the AMF 544 may be a termination point of NAS (Nl) signaling, and perform NAS ciphering and integrity protection. AMF 544 may also support NAS signaling with the UE 502 over an N3 IWF interface.
The SMF 546 may be responsible for SM (for example, session establishment, tunnel management between UPF 548 and AN 508); UE IP address allocation and management (including optional authorization); selection and control of UP function; configuring traffic steering at UPF 548 to route traffic to proper destination; termination of interfaces toward policy control functions; controlling part of policy enforcement, charging, and QoS; lawful intercept (for SM events and interface to LI system); termination of SM parts of NAS messages; downlink data notification; initiating AN specific SM information, sent via AMF 544 over N2 to AN 508; and determining SSC mode of a session. SM may refer to management of a PDU session, and a PDU session or “session” may refer to a PDU connectivity service that provides or enables the exchange of PDUs between the UE 502 and the data network 536.
The UPF 548 may act as an anchor point for intra-RAT and inter-RAT mobility, an external PDU session point of interconnect to data network 536, and a branching point to support multi-homed PDU session. The UPF 548 may also perform packet routing and forwarding, perform packet inspection, enforce the user plane part of policy rules, lawfully intercept packets (UP collection), perform traffic usage reporting, perform QoS handling for a user plane (e.g., packet filtering, gating, UL/DL rate enforcement), perform uplink traffic verification (e.g., SDF-to-QoS flow mapping), transport level packet marking in the uplink and downlink, and perform downlink packet buffering and downlink data notification triggering. UPF 548 may include an uplink classifier to support routing traffic flows to a data network. The NSSF 550 may select a set of network slice instances serving the UE 502. The NSSF 550 may also determine allowed NSSAI and the mapping to the subscribed S-NSSAIs, if needed. The NSSF 550 may also determine the AMF set to be used to serve the UE 502, or a list of candidate AMFs based on a suitable configuration and possibly by querying the NRF 554. The selection of a set of network slice instances for the UE 502 may be triggered by the AMF 544 with which the UE 502 is registered by interacting with the NSSF 550, which may lead to a change of AMF.

NEF 552 may also translate information exchanged with the AF 560 and information exchanged with internal network functions. For example, the NEF 552 may translate between an AF-Service-Identifier and an internal 5GC information. NEF 552 may also receive information from other NFs based on exposed capabilities of other NFs. This information may be stored at the NEF 552 as structured data, or at a data storage NF using standardized interfaces. The stored information can then be re-exposed by the NEF 552 to other NFs and AFs, or used for other purposes such as analytics. Additionally, the NEF 552 may exhibit an Nnef service-based interface.

In addition to communicating with functions over reference points as shown, the PCF 556 exhibit an Npcf service-based interface.
The UDM 558 may handle subscription-related information to support the network entities’ handling of communication sessions, and may store subscription data of UE 502. For example, subscription data may be communicated via an N8 reference point between the UDM 558 and the AMF 544. The UDM 558 may include two parts, an application front end and a UDR. The UDR may store subscription data and policy data for the UDM 558 and the PCF 556, and/or structured data for exposure and application data (including PFDs for application detection, application request information for multiple UEs 502) for the NEF 552. The Nudr service-based interface may be exhibited by the UDR 221 to allow the UDM 558, PCF 556, and NEF 552 to access a particular set of the stored data, as well as to read, update (e.g., add, modify), delete, and subscribe to notification of relevant data changes in the UDR. The UDM may include a UDM-FE, which is in charge of processing credentials, location management, subscription management and so on. Several different front ends may serve the same user in different transactions. The UDM-FE accesses subscription information stored in the UDR and performs authentication credential processing, user identification handling, access authorization, registration/mobility management, and subscription management. In addition to communicating with other NFs over reference points as shown, the UDM 558 may exhibit the Nudm service-based interface.
The AF 560 may provide application influence on traffic routing, provide access to NEF, and interact with the policy framework for policy control.
In some embodiments, the 5GC 540 may enable edge computing by selecting operator/3rd party services to be geographically close to a point that the UE 502 is attached to the network. This may reduce latency and load on the network. To provide edge-computing implementations, the 5GC 540 may select a UPF 548 close to the UE 502 and execute traffic steering from the UPF 548 to data network 536 via the N6 interface. This may be based on the UE subscription data, UE location, and information provided by the AF 560. In this way, the AF 560 may influence UPF (re)selection and traffic routing. Based on operator deployment, when AF 560 is considered to be a trusted entity, the network operator may permit AF 560 to interact directly with relevant NFs. Additionally, the AF 560 may exhibit an Naf service-based interface.
The data network 536 may represent various network operator services, Internet access, or third party services that may be provided by one or more servers including, for example, application/content server 538.
