Description

Technical Field

[0001] Some example embodiments may generally relate to mobile or wireless telecommunications systems, such as Long Term Evolution (LTE) or 5th Generation (5G) New Radio (NR) access technologies, or 5G evolution, or 6th Generation (6G) access technologies, or other communication systems. For example, some example embodiments may relate to cell reselection and coverage enhancement. Background Technology

[0002] Examples of mobile or wireless telecommunications systems can include Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (UTRAN), Evolved Long Term Evolution (LTE) UTRAN (E-UTRAN), Advanced LTE-A (LTE-A), MulteFire, LTE-APro, fifth-generation (5G) radio access technology or new radio (NR) access technology and / or sixth-generation (6G) radio access technology. Fifth-generation (5G) and sixth-generation (6G) radio systems refer to next-generation (NG) radio systems and network architectures. While 5G and 6G network technologies are largely based on new radio (NR) technology, 5G / 6G (or NG) networks can also be built on E-UTRAN radio. It is estimated that NR can provide bit rates of approximately 10-20 Gbit / s or higher and can at least support enhanced mobile broadband (eMBB) and ultra-reliable low-latency communications (URLLC) as well as massive machine-type communications (mMTC). NR is expected to provide extremely high bandwidth and ultra-robust, low-latency connectivity and massive networks to support the Internet of Things (IoT). Summary of the Invention

[0033] It should be readily understood that the components of certain example embodiments, as generally described and illustrated in the accompanying drawings, can be arranged and designed in a variety of different configurations. The following is a detailed description of some example embodiments of systems, methods, apparatuses, and computer program products for cell reselection and coverage enhancement. For example, some example embodiments may relate to cell reselection measurement rules for coverage enhancement.

[0034] The features, structures, or characteristics of the exemplary embodiments described throughout this specification can be combined in any suitable manner in one or more exemplary embodiments. For example, the use of phrases such as "certain embodiments," "exemplary embodiments," "some embodiments," or other similar language throughout this specification means that a particular feature, structure, or characteristic described in connection with an embodiment can be included in at least one embodiment. Therefore, the appearance of phrases such as "in some embodiments," "exemplary embodiments," "in some embodiments," "in other embodiments," or other similar language throughout this specification does not necessarily refer to the same set of embodiments, and the described features, structures, or characteristics can be combined in any suitable manner in one or more exemplary embodiments. Furthermore, the terms "base station," "cell," "node," "gNB," "network," or other similar language throughout this specification can be used interchangeably.

[0035] As used herein, “at least one of the following: <two or more elements>” and “at least one of the <list of two or more elements>” and similar wording, wherein the list of two or more elements is connected by “and” or “or”, means at least any one of the elements, or at least any two or more of the elements, or at least all of the elements.

[0036] In the 3GPP (3rd Generation Partnership Project) specifications, Low Power Wide Area (LWPA) networks can be used to support Internet of Things (IoT) devices. For example, in 4G LTE, LWPA networks based on Narrowband IoT (NB-IoT) and Long Term Evolution Machine Type Communication (LTE-M) technologies have been introduced. In 5G, no new LPWA technology is specified as in NB-IoT, and LTE-M continues to be supported for large-scale IoT use cases.

[0037] Figure 1 An example LPWA deployment is shown within the frequency band of an enhanced mobile broadband (eMBB) carrier. Figure 1 The deployment scenarios illustrated allow for efficient spectrum utilization, especially in the early stages of LPWA deployments where there may not be many LPWA devices (e.g., IoT UEs) in the system. Furthermore, LWPA carriers can offer significantly enhanced coverage (e.g., up to 20-25 dB greater coverage) compared to eMBB carriers. To effectively support UEs under various radio link coverage conditions, LPWA cells can support multiple coverage enhancement (CE) levels. Support for multiple CE levels allows UEs to access the cell at the appropriate coverage enhancement level. For example, LTE-M and NB-IoT can support up to three different CE levels that can be configured by the network.

[0038] Table 1 shows an example of CE level configuration by the network based on Maximum Coupling Loss (MCL), which is determined by the UE based on Reference Signal Received Power (RSRP) measurements. In the example shown in Table 1, CE0 is used by UEs under normal coverage (e.g., UEs with RSRP measurements higher than the configured threshold). CE1 is used by UEs requiring coverage enhancement of no more than 10 dB above normal, while CE2 is used by UEs requiring coverage enhancement of 10 dB to 20 dB. To achieve the CE level, the network can configure different resources, such as time-frequency resources (e.g., Physical Random Access Channel (PRACH) and Physical Downlink Control Channel (PDCCH)), different maximum repetition counts (e.g., for PRACH, Physical Uplink Shared Channel (PUSCH), PDCCH, and Physical Downlink Shared Channel (PDSCH)), and different radio configurations (e.g., Modulation and Coding Scheme (MCS) tables, resource allocation schemes, modulation schemes, retransmission counts, etc.).

[0039] IoT devices can have infrequent data transmissions with small data packets. In NR, a Small Data Transmission (SDT) procedure has been defined to support data transmission in the RRC_INACTIVE state without transitioning to the RRC_CONNECTED state. SDT in the RRC_IDLE state is also considered. This can save significant Radio Resource Control (RRC) overhead and reduce data transmission latency. For UEs in idle and inactive states, cell selection or reselection procedures can be performed periodically. To limit co-frequency measurements (i.e., measurements of co-frequency or neighboring cells), certain measurement rules can be used for cell reselection in NR. A co-frequency cell is a cell that uses the same frequency as the serving cell. Examples of measurement rules are shown below, where for cells supporting CE, the threshold S... IntraSearchP and SIntraSearchQ It can be configured to support low SNR / SINR values ​​accordingly: "If the serving cell satisfies Srxlev>S" IntraSearchP And Squal>S IntraSearchQ : If distanceThresh and referenceLocation are broadcast in SIB19, and if the UE supports location-based measurement initiation and has already obtained its location information: If the distance between the UE and the serving cell reference location is shorter than distanceThresh, the UE may not need to perform co-frequency measurement; Otherwise, the UE should perform in-frequency measurements; Otherwise, the UE may choose not to perform co-frequency measurements; Otherwise, the UE should perform in-frequency measurements. In the above rules, Srxlev is the cell selection RX level value, Squal is the cell selection quality value, and S... IntraSearchP It is the Srxlev threshold configured by the network for same-frequency measurements, and S IntraSearchQ The Squal threshold is configured by the network for same-frequency measurements. In some example embodiments, S... IntraSearchP It can be broadcast in System Information Block Type 2 (SIB2).

[0040] Compared to eMBB carriers, LWPA carriers can offer significantly enhanced coverage to support devices deployed in harsh radio conditions (e.g., underground, basements, etc.). For example, in NB-IoT, devices can support network connections with low signal-to-interference-to-noise ratios (SINR) such as -20 dB. Furthermore, IoT devices may have infrequent data transmissions of small data packets. This infrequent transmission of small data packets makes IoT devices suitable for SDT procedures, where the UE remains in the RRC_INACTIVE state without transitioning to the RRC_CONNECTED state. For UEs in the RRC_IDLE and RRC_INACTIVE states, cell reselection procedures can be performed periodically. To limit co-frequency measurements, the measurement rules for cell reselection stipulate that the UE generally will not perform measurements on other cells if the serving cell meets the following parameter: Srxlev > S IntraSearchP And Squal>S IntraSearchQ The parameter Srxlev corresponds to the cell selection RX level (dB), Squal corresponds to the cell selection quality (dB), and S... IntraSearchP Specify the Srxlev threshold (in dB) for use in same-frequency measurements, and S IntraSearchQThe Squal threshold (in dB) for co-frequency measurements is specified. The Srxlev value can be determined based on RSRP measurements, while the Squal value can be determined based on Reference Signal Received Quality (RSRQ) measurements. For cells supporting coverage enhancement, the threshold S... IntraSearchP and S IntraSearchQ The network can be configured to support low signal-to-noise ratio (SNR) / signal-to-interference-to-noise ratio (SINR) values ​​accordingly.

[0041] Although the above parameters can be provided to perform cell measurements, because S IntraSearchP and S IntraSearchQ The settings support low SNR / SINR values, so idle / inactive UEs with weak radio conditions remain connected to the worse cell and do not switch to a better cell when one becomes available (e.g., no cell reselection). For example, Figure 2 An example cell reselection with coverage enhancement is shown. (e.g.) Figure 2 As shown, both UE1 and UE2 reside on gNB1 because gNB1 can support coverage as low as -20dB. If the network is configured with S... IntraSearchQ A threshold prevents UEs with SINR > -10dB from performing measurements for cell reselection, so UE2 will not recognize gNB2 as a better cell. Therefore, when UE2 has data to send / receive, it will select the worst cell, which in this example would be gNB1. Given these drawbacks, some example embodiments described herein provide a way to prevent LPWA UEs in coverage enhancement mode from remaining connected to a poor cell when a better cell is available. In doing so, the need to perform co-frequency measurements in other cells can be minimized.

[0042] Some example embodiments described herein can provide solutions for modifying measurement rules used for cell reselection to add additional checks. Some example embodiments can also provide a solution that, without modifying the measurement rules, instructs the UE to perform cell selection measurements under certain conditions when data arrives (e.g., receiving application data, control plane data, measurement data, and other similar types of data that have arrived at the UE and can be transmitted to the network). Both solutions can be applied to all LPWA UEs or to UEs under coverage enhancement (e.g., the RSRP of the camped cell is below a threshold).

[0043] According to certain example embodiments, various additional criteria / checks can be utilized in solutions that modify measurement rules for cell reselection. In some example embodiments, the criteria / checks may be given by the gNB or defined in the specification. The various criteria described herein may be added individually or in any combination of one or more other criteria. For example, a criterion may include adding additional S...IntraSearchP_2 and S IntraSearchQ_2 A threshold allows a UE in weak coverage area to perform measurements. For example, if the signal level is above a first threshold but below a second threshold, the UE can perform measurements on, for example, neighboring cells or cells within the same cellular network. Measurements can be performed on the same or different carrier frequency bands (e.g., on the same frequency or on different frequencies).

[0044] According to some example embodiments, other criteria may include adding a stationary criterion to the cell reselection rules. In other words, in this criterion, the UE may be moving or has moved since its last measurement and requires additional / new measurements. For example, if the change in RSRP or Srxlev or Squal values ​​has exceeded a threshold, the UE may perform a co-frequency measurement. In other example embodiments, the UE may use location information such as Global Navigation Satellite System (GNSS) to determine whether it has moved. In still other example embodiments, for LPWA UEs capable of determining their own Timing Advance (TA), the UE may determine the TA before performing a measurement and use this information to compare it with the last determined TA. If the difference is higher than a predetermined or configured threshold, the UE may perform the measurement.

[0045] According to some example embodiments, other criteria may include adding distance-based criteria to the cell reselection rules. Distance-based criteria may include checking how far the UE is from the serving cell or the cell where the UE is camped. For example, the UE may determine the propagation delay via ReferenceTimeInfo in Synchronization Information Block 9 (SIB9), thereby determining how far it is from the camped gNB. ReferenceTimeInfo may correspond to IE ReferenceTimeInfo, which includes timing information for the 5G internal system clock, which may be used, for example, to generate timestamps.

[0046] According to some example embodiments, other criteria may include adding distance-based criteria to estimate the distance to a certain number of nearest neighboring gNBs. For example, the UE may use round-trip time (RTT) measurements performed with neighboring gNBs for positioning purposes to estimate how far the UE is from the nearest number of gNBs. If the UE is closer to a neighboring gNB than the serving gNB, and the distance difference is greater than a certain threshold (e.g., configured by the gNB / network), the UE may determine to perform a measurement (e.g., a co-frequency measurement).

[0047] In some example embodiments, other criteria may include adding an additional check on the difference between RSRP and RSRQ to determine whether the UE has detected strong interference, which may originate from neighboring cells. For example, if the difference between RSRP and RSRQ is higher than a threshold, the UE may perform a measurement, such as a co-frequency or inter-frequency measurement. Alternatively, in other example embodiments, this additional check may be performed based on the UE implementation. For example, the UE may check the interference level and, if the interference level is high, such as above a predetermined or configured threshold, perform a co-frequency or inter-frequency measurement.

[0048] According to some example embodiments, other criteria may include adding additional checks to use indicators associated with measurements from neighboring gNBs. For example, in some example embodiments, the UE may use a Measurement Quality Indicator (MQI) associated with measurements performed with neighboring cells (e.g., timing or angle measurements performed for positioning purposes) to determine whether to perform co-frequency measurements for cell selection. The MQI may be acquired by the UE to indicate to the network the quality and accuracy of the co-frequency measurements acquired by the UE. The MQI may also help the UE indicate to the network how confident it is in the measurements it has acquired and whether the measurements are reliable. For example, if the MQI of a neighboring gNB is significantly better than the MQI of the serving cell, the UE may determine to trigger the performance of measurements on the neighboring cell for cell selection.

[0049] In other example embodiments, the UE can use line-of-sight (LOS) as an indicator of neighboring gNBs to determine whether to perform a measurement. For example, if the UE has an LOS connection with a neighboring gNB and a non-line-of-sight (NLOS) connection with the serving gNB, the UE can trigger a cell selection process.

[0050] In some example embodiments, other criteria may include adding an additional timer under which LPWAUE can at least every T priority =X (minutes) to perform co-frequency measurements. For example, if the serving cell satisfies Srxlev>S IntraSearchP And Squal>S IntraSearchQ Then the UE can at least every T priority Perform same-frequency measurement.

[0051] According to some example embodiments, other criteria may include adding a list of time instances with predetermined time periods during which the UE can perform co-frequency measurements. For example, a gNB may be turned off during periods of heavy traffic (e.g., at night) and reactivated during periods of normal traffic. Similarly, some gNBs may be turned on during peak traffic periods to obtain additional capacity. When the cell on which the UE is camped is turned off, the UE may camp on another (remote) cell. The original cell may be reactivated at a later time. In other example embodiments, the UE may perform co-frequency measurements at a configured time corresponding to the time the gNB is turned on (e.g., during a 24-hour period).

[0052] In some example embodiments, the UE can be configured not to perform co-frequency measurements for a certain period of time (e.g., based on a timer) if the UE cannot find a better cell after performing measurements. In some example embodiments, the network can configure the UE using a timer value. In other example embodiments, the network can configure criteria to be used by the UE for measurement rules when an RRC connection is released, as part of an RRC ConnectionRelease message. By configuring the UE in this way, UE-specific measurement rules that are particularly relevant to the UE's capabilities can be implemented.

[0053] According to some example embodiments, the criteria included in the RRC connection release message may represent independent information. For example, the RRC connection release message may include a complete set of criteria to be used at the UE, without any links to predetermined or broadcast-acquired criteria. According to other example embodiments, the RRC release message may include incremental information relative to predetermined (default) or broadcast-acquired criteria. For example, the RRC connection release message may include (additional) S criteria for defining based on UE capabilities and based on an initial threshold provided to the UE via broadcast from the network. IntraSearchP and S IntraSearchQ Threshold rules.

[0054] Examples of implementing additional criteria / rules for cell reselection may include: "If the serving cell satisfies Srxlev>S" IntraSearchP_1 And Squal>S IntraSearchQ_1 : If the serving cell satisfies Srxlev IntraSearchP_2 and Squal IntraSearchQ_2 If the UE is stationary, the UE may not perform co-frequency measurements; Otherwise, the UE should perform in-frequency measurements; Otherwise, the UE may choose not to perform co-frequency measurements; ​​Otherwise, the UE should perform in-frequency measurements.

[0055] As shown in the example above, additional signal level checks and stationary checks have been added. For example, if the SINR level is above -10dB (first threshold) but below 0dB (second threshold), the UE can check if it is stationary. If the UE is stationary, it does not perform a same-frequency measurement. However, if the UE is not stationary, it performs a same-frequency measurement.

[0056] Another example of implementing additional criteria / rules for cell reselection could be: "If the serving cell satisfies Srxlev>S" IntraSearchP_1 And Squal>S IntraSearchQ_1 : If the difference between Srxlev and Squal is below the threshold, the UE may not perform in-frequency measurement; Otherwise, the UE should perform in-frequency measurements; Otherwise, the UE should perform in-frequency measurements.

[0057] As shown in the example above, an additional interference level check can be added based on the difference between the Srxlev and Squal values. If the difference between the Srxlev and Squal values ​​is below a threshold (e.g., low interference level), the UE does not perform co-channel measurement. However, if the difference between the Srxlev and Squal values ​​is greater than the threshold, or greater than or equal to the threshold, the UE performs co-channel measurement.

[0058] Another example of implementing additional criteria / rules for cell reselection could be: "If the serving cell satisfies Srxlev>S" IntraSearchP_1 And Squal>S IntraSearchQ_1 : If the serving cell satisfies Srxlev IntraSearchP_2 and Squal IntraSearchQ_2 If the difference between Srxlev and Squal is below the threshold, the UE may not perform in-frequency measurement; Otherwise, the UE should perform in-frequency measurements; Otherwise, the UE may choose not to perform co-frequency measurements; Otherwise, the UE should perform in-frequency measurements.

[0059] ​​As shown in the example above, additional signal level checks and interference level checks can be added. For example, if the SINR level is higher than -10dB (first threshold) but lower than 0dB (second threshold), the UE checks if the interference is below the threshold. If so, the UE does not perform a co-channel measurement. However, if the interference is higher than or equal to the threshold, the UE performs a co-channel measurement.

[0060] In some example embodiments, no modification is made to the cell reselection process in solutions that do not modify the rules. However, when data arrives at the UE, the UE may perform a cell selection process under certain conditions to select the best cell before the first access attempt. For example, if the serving cell satisfies Srxlev>S IntraSearchP_2 And Squal>S IntraSearchQ_2 If the serving cell does not satisfy Srxlev>S, then no measurements are needed for cell selection before the initial access attempt. IntraSearchP_2 And Squal>S IntraSearchQ_2 If the UE fails to perform cell selection, it will perform a cell selection measurement to check for a better cell. In some example embodiments, the UE may perform cell selection over a certain period of time, which may be configured by the network as part of the RRC-Release or provided in the 3GPP specification. Otherwise, the UE may connect to an already camped cell.

[0061] According to certain example embodiments, if the serving cell satisfies Srxlev IntraSearchP_2 and Squal IntraSearchQ_2 If so, the UE performs a measurement cell selection before the first access attempt. According to some example embodiments, any condition or any combination of conditions presented above can be used as a trigger condition for the UE to determine whether to perform the cell selection process before the first access attempt.

[0062] According to some example embodiments, not modifying the cell reselection process may be applicable to UEs where paging is unlikely to occur, as is the case in many IoT use cases. According to some example embodiments, the gNB may indicate one or more criteria or conditions in the paging message for the UE to determine whether cell selection measurements are required. The conditions indicated in the paging message may be UE-specific parameters rather than cell-specific parameters.

[0063] In some example implementations, when a mobile terminal terminates service after being paged by the UE, the UE can also perform measurements for cell selection before the initial access attempt. This means that the UE can perform initial access in a different cell than the cell in which the paging message was received.

[0064] Figure 3 Example signal diagrams according to certain example embodiments are shown. Specifically, Figure 3 ​​The example illustrates the addition of additional signal level checks and interference level checks for performing cell reselection. At 315, gNB 1 305 sends a System Information Block (SIB) to UE 300. The SIB can define the RSRP threshold, S... IntraSearchP_1 S IntraSearchQ_1 S IntraSearchP_2 S IntraSearchQ_2 And the interference threshold. At 320, the UE is in the RRC_INACTIVE state. However, in other example embodiments, the UE may be in the RRC_IDLE state. At 325, gNB 1 305 sends a Synchronization Signal Block (SSB) to UE 300. In some example embodiments, the SSB may include a synchronization signal and a Physical Broadcast Channel (PBCH), where the PBCH may include a Master Information Block (MIB). At 330, UE 300 wakes up in response to the SSB received from gNB 1 305 and performs co-channel measurements of the cell where UE 300 is camped. At 335, UE 300 performs a check to see if the RSRP value is below a threshold. At 340, the UE performs another check to see if Srxlev and Squal meet two thresholds.
