PRIORITY INFORMATION
[0001] This application claims priority over the preliminary US application No. 62 / 832,026 entitled “Selective Measurement of Neighbor Base Stations”, filed on April 10, 2019, which is hereby incorporated by reference in its entirety as if set forth herein in its entirety and in full.
[0002] The claims in the present application differ from those of the parent application or other related applications. The applicant therefore withdraws all waivers regarding the scope of claims made in the parent application or any previous application relating to the present application. The examiner is therefore advised that any such prior waiver and the references cited to avoid it may need to be revised. Furthermore, any waiver made in the present application should not be interpreted as being in or against the parent application or other related applications. TECHNICAL AREA
[0003] The present application relates to wireless devices and, in particular, to facilities, systems and methods for obtaining requested system information. DESCRIPTION OF THE STATE OF THE ART
[0004] The use of wireless communication systems is increasing rapidly. Wireless devices, especially wireless user equipment (UEs), are now widespread. Furthermore, there are numerous applications (or apps) hosted on UEs that perform or depend on wireless communication, such as applications that provide messaging, email, browsing, video streaming, short videos, voice streaming, real-time gaming, or various other online services.
[0005] In some cases, for example with 5G NR (New Radio), some system information is transmitted periodically by a mobile network, while other system information is available on demand. However, determining when to query the requested system information can depend on a single UE (User Unit). Furthermore, communication errors (e.g., of a random access channel) can disrupt such queries of requested system information, and determining how to overcome such a problem can depend on a single UE. Therefore, improvements in this area are desirable. SUMMARY

The UE can include at least one antenna for performing wireless communications, a radio device coupled to the at least one antenna, and a processing element coupled to the radio link, and can be configured to communicate wirelessly with a wireless network (e.g., a cellular network) via at least one type of radio access technology (RAT).
[0007] In some embodiments, the UE can receive a list of neighboring base stations from the servicing base station. The UE can classify the neighboring base stations in the list into one of several measurement categories. The UE can be configured to perform measurements of neighboring base stations in each category at different rates.
[0008] In some embodiments, a non-volatile storage medium may contain program instructions executable by a UE, which, when executed, cause the UE to perform at least some or all of the foregoing operations. In some embodiments, a procedure performed by the UE may include the UE performing the foregoing operations. In some embodiments, a procedure performed by a base station or network element may include the base station or network element performing corresponding operations.

FIGURES 6-7 - 5G-NR-ARCHITECTURE
[0057] In some implementations, fifth-generation wireless communication ( 5G) Initially deployed simultaneously with other wireless communication standards (e.g., LTE). For example, during Fig. 6. A possible standalone (SA) implementation of a core network 606 next generation (NGC) and a 5G NR base station (e.g. gNB) 604 ) illustrates dual connectivity between LTE and 5G New Radio ( 5G NR or NR), such as according to the exemplary non-independent (NSA) architecture, as in Fig. Figure 7 illustrates this as part of the initial deployment of NR. Thus, as shown in Fig. Figure 7 illustrates the Evolved Packet Core Network (EPC Network) 600 continue to use the current LTE base stations (e.g. eNB) 602 ) communicate. Additionally, the eNB can 602 with a 5G NR base station (e.g. gNB) 604 ) communicate and transfer data between the EPC network 600 and the gNB 604 transferred. In some cases, the gNB can 604 also at least one user-level reference point with the EPC network 600 have. Thus, the EPC network can 600 used (or reused) and the gNB 604LTE can serve as additional capacity for user entities (UEs), for example, to provide UEs with increased downlink throughput. In other words, LTE can be used for control plane signaling, and NR can be used for user plane signaling. Thus, LTE can be used to establish connections to the network, and NR can be used for data services. It is understood that numerous other non-standalone architectural variations are possible.

SELECTIVE MEASUREMENT OF NEIGHBORING BASE STATIONS
[0060] According to wireless standards (e.g., NR RRC patent TS 38331), a mobile network (e.g., a base station or other wireless network node) can configure neighbor base station measurements in idle and connected modes (e.g., intrafrequency, interfrequency, or inter-RAT). However, the network cannot specify a priority or differentiated rate for performing measurements for each neighbor base station.
[0061] Thus, in some embodiments, the UE can be configured to determine a priority for performing neighboring base station measurements, e.g., from the neighbor list provided by the network. This prioritization can provide a better mobility experience and / or battery life for the UE.
[0062] In some embodiments, by default all neighboring measurement candidates configured by the network can be part of a “default” group that can be measured with a standard measurement rate and / or periodicity (e.g., specified in 3GPP TS 36.133).
[0063] The UE can be configured to move or otherwise categorize one or more of these candidate neighboring base stations into a “fast measurement group” (FMG) or a “slow measurement group” (SMG).
[0064] Neighbors enclosed in the FMG can be measured at a relatively high rate and periodicity (which can be adjustable, for example) compared to the specified measurement rate and periodicity, whereas neighbors enclosed in the SMG can be measured at a relatively low speed and periodicity (which can be adjusted, for example) compared to the specified measurement rate and periodicity.
[0065] According to some embodiments, whenever the network configures the UE to perform measurements (e.g., for idle measurements or in connected mode), the UE (e.g., the UE's RRC layer) can use one or more of the following criteria to categorize base stations from the neighbor cell list and place them in the FMG (e.g., together with the servicing cell), so that these neighbor base stations are prioritized for an improved mobility procedure, or in the SMG.
[0066] Generally, if the neighboring base station is configured or supports policies to allow the UE to quickly and efficiently take measurements from it, this neighboring base station can be placed in the FMG (Field Measurement Group). However, if the neighboring base station is not configured or does not support policies to allow the UE to quickly and efficiently take measurements from it, this neighboring base station can be placed in the SMG (Standard Measurement Group). If a default group is used, neighboring base stations that are neither easy to measure nor problematic can remain in the default group. The following criteria are non-exhaustive and non-restrictive examples for categorizing neighboring base stations.
[0067] In some embodiments, the UE may attempt to detect the SIB before starting measurements on a specific neighbor. 1The UE reads the neighbor's PLMN and then determines the PLMN (Public Land Mobile Network) of the neighboring cell. If the neighboring cell's PLMN is not the HPLMN (Home PLMN) or the EHPLMN (Equivalent HPLMN), then the UE can place the specified neighbor in the SMG. If the PLMN is HPLMN or EHPLMN, the UE can place the specified neighbor in the FMG and / or leave it in the default group (e.g., as desired and / or depending on whether a default group is used).
[0068] In some embodiments, the UE can place this neighbor candidate in the FMG if a particular neighbor supports a dual connectivity configuration (e.g., ENDC or MRDC configuration) (which may be indicated, for example, in the neighbor's transmission message). In one embodiment, the UE can determine whether the neighbor base station supports dual connectivity in one or more transmission messages from the neighbor base station.
[0069] In some embodiments, if the network (e.g., the servicing base station, such as in measurement configuration messages to the UE) indicates that a neighboring cell is configured with `deriveSSB-IndexFromCell`, that neighbor can be added as part of the FMG. `deriveSSB-IndexFromCell` can indicate whether the UE can use timing settings of the servicing cell to derive the index of the SS block transmitted by the neighboring cell. For example, if this field is set to "true," the UE can assume SFN and frame limit alignment across cells on the servicing frequency, as specified in TS 38.133.
[0070] In some embodiments, if the network (e.g., the operating base station, such as in measurement configuration messages to the UE) indicates that the UE should perform gapless measurements on a particular neighbor, the UE can add this neighbor candidate to the FMG.
[0071] In some embodiments, if the network (e.g., the servicing base station, such as in measurement configuration messages to the UE) specifies a particular measurement gap scheme for a neighbor to the UE, the UE can add the neighbor to the FMG based on the measurement gap scheme and other parameters configured for measurements. These parameters indicate that the specific neighbor has more opportunities to be measured (e.g., more often than other neighbors or typical neighbors).
[0072] In some embodiments, if the network (e.g., the serving base station, as in measurement configuration messages to the UE) indicates that a particular neighbor frequency is configured with PCI ranges (e.g., specified by the network based on deployment, coverage, UE Assistance Info, etc.), this neighbor can be added as part of the FMG.
[0073] In some embodiments, if the network (e.g., the operating base station, such as in measurement configuration messages to the UE) indicates that a particular neighboring cell is configured as “false” with intraFreqReselection, this neighbor can be added as part of the SMG.
[0074] In some embodiments, if the network (e.g., the operating base station, such as in measurement configuration messages to the UE) indicates that a particular neighboring cell is configured with eCallOverIMSSupport, this neighboring frequency can be added to the FMG, e.g., if the UE is in limited service mode or is about to initiate an emergency call.
[0075] In some implementations, if the network (e.g., the servicing base station, such as in measurement configuration messages to the UE) indicates that a particular neighboring cell has a pre-RRC configuration, this neighboring frequency can be added as part of the FMG. For example, if the servicing base station supports faster handover, it can provide a preconfiguration of the target neighboring base station to the UE. This preconfiguration can then enable the UE to perform a faster handover procedure instead of having to wait for the network to provide this information after the handover criteria have been met (e.g., once the UE transmits a measurement report).
[0076] In some embodiments, if the UE adds the `connEstFailOffsetValidity` value to a specific serving or neighboring cell, and / or if no suitable or acceptable cell is found for that particular cell, the UE can then add it to the SMG. More generally, for problematic cells, e.g., based on a history of problems identified by the UE or any data indicating that the cell is problematic, the UE can add the neighbor to the SMG.
[0077] In some embodiments, a particular neighbor can be placed in the FMG if it meets any of the criteria for the FMG, regardless of other criteria.
[0078] In some embodiments, the UE can have many entries in the FMG after categorizing the neighbor list. In some embodiments, if the FMG list has more than a threshold number of entries, the UE can order the entries according to the number of matching criteria and / or based on a prioritized list of criteria (e.g., if some criteria are more important than others) and select the threshold number of (configurable) neighbors. In some embodiments, FMG and / or SMG can be measured in a prioritized order.
[0079] It should be noted that, while the descriptions presented here refer to the FMG and the SMG, there can be more than two subdivisions for the neighbor list. For example, there can also be a default group for all neighbors that do not match the criteria for either the FMG or the SMG. Thus, the FMG may be measured more frequently or with a higher priority than the default group, which in turn may be measured more frequently or with a higher priority than the SMG.
[0080] Furthermore, it should be noted that, although the descriptions herein are from the perspective of the UE, any or all of these embodiments can also be implemented on the network side (e.g., by one or more base stations or other network nodes). For example, the network can be configured to divide the neighbor list into one or more categories and / or to prioritize one or more (or a plurality of or all) entries in the neighbor list and to indicate this segregation or prioritization after it has been provided to the UE, or at another time. FIGURE 9 - SELECTIVE MEASUREMENT OF NEIGHBORING CELLS
[0081] Fig. Figure 9 illustrates exemplary techniques for performing a selective measurement of neighboring cells. Aspects of the procedure are discussed. Fig.9 can communicate with one or more base stations (e.g. BS) via a wireless device, such as the UE(s) 106. 102 ), as illustrated in and described in the figures, or more generally, in conjunction with any of the computer systems or devices shown in the figures, alongside other switching logics, systems, devices, elements, or components shown in the figures, among other devices, as desired. For example, one or more processors (or processing elements) of the UE (e.g., the one or more processors linked with communication switching logic) can be implemented as desired. 402, (a) baseband processor(s), (a) processor(s) associated with communication circuits, etc., among various possibilities) cause the UE to perform some or all of the illustrated method elements. It should be noted that although at least some elements of the method are described in a manner relating to the use of communication techniques and / or features associated with 3GPP specification documents, this description is not intended to limit the disclosure, and aspects of the method may be used, as desired, in any suitable wireless communication system. In various embodiments, some of the elements of the illustrated methods may be performed simultaneously or in a different order than shown, replaced by other method elements, or omitted. Furthermore, additional method elements may be performed as desired.As shown, the procedure can work as follows.
[0082] The UE (e.g. UE) 106 ) can connect to an operating base station ( 902 ) connect.
[0083] The UE can receive a neighboring base station list from the servicing base station (904). The neighboring base station list can include a multitude of neighboring base stations (cells) from which the UE can be configured to perform periodic measurements (e.g., intrafrequency, interfrequency, and / or InterRAT measurement). The UE can compare a first neighboring base station in the neighboring base station list against one or more criteria, such as, among others, those described above (906). The UE can categorize the first neighboring base station into one of a multitude of measurement groups based on the comparison against the criteria ( 908For example, as discussed above, the UE can categorize the first neighboring base station as part of the FMG or the SMG. In one embodiment, if the neighboring base station is not categorized as part of the FMG, it can be categorized as part of the SMG. Alternatively, the UE can categorize the first neighboring base station as part of the FMG, the standard group, or the SMG. In some embodiments, if one or more criteria do not classify the first neighboring base station as part of the FMG or SMG, it can remain in the standard group.
[0084] The categorization can be based on information received from the base station (e.g., information provided by the operating base station regarding the first neighboring base station). Alternatively or additionally, the categorization can be based on information received from the first neighboring base station (e.g., information transmitted by the first neighboring base station). As another possibility, the categorization can be based on information stored by the UE about the neighboring base station. The categorization can also be based on the UE's configuration or its current conditions (e.g., battery status, connectivity, or signal strength, etc.).
[0085] The UE can repeat 906 and 908 for one or more additional neighboring base stations in the neighboring base station list. In one embodiment, the UE can 906 until 908repeat for each of the neighboring base stations in the neighboring base station list, although it is possible to perform this categorization only for fewer than all neighboring base stations in the neighboring base station list (e.g., a strict subset) if desired.
[0086] As mentioned above, the UE can be configured, after categorizing a large number (or all) of the neighboring base stations, to reduce or modify the categorizations, for example, based on thresholds. For instance, only a limited number of neighboring base stations may be allowed in the FMG or SMG, and the UE can be configured to prioritize and select based on this threshold within the relevant group, as desired.
[0087] The UE can perform a neighbor base station measurement based on the categorization. For example, the UE can perform measurements for neighbor base stations in the FMG at a higher rate and / or periodicity than measurements for neighbor base stations in the SMG. If a default group is used, measurements for neighbor base stations in the specified group can be performed less frequently than in the FMG, but more frequently than in the SMG.
