METHODS FOR MEASUREMENT ENHANCEMENTS IN MOBILE COMMUNICATIONSCROSS REFERENCE TO RELATED PATENT APPLICATION (S)
[0001] The present disclosure is part of a non-provisional application claiming the priority benefit of U.S. Patent Application No. 63 / 554,253, filed 16 February 2024, the content of which herein being incorporated by reference in its entirety.TECHNICAL FIELD
[0002] The present disclosure is generally related to mobile communications and, more particularly, to measurement enhancements with respect to user equipment in mobile communications.BACKGROUND
[0003] Unless otherwise indicated herein, approaches described in this section are not prior art to the claims listed below and are not admitted as prior art by inclusion in this section.
[0004] Fifth generation (5G) services like extended reality (XR) demand low-latency, high data rate transmissions on both uplink and downlink channels. However, limited spectrum resources constrain the network's capacity to support numerous user equipments (UEs) within a cell. High XR packet data rates necessitate the allocation of wide frequency bands to each user. Additionally, stringent latency requirements mandate the swift assignment of sufficient frequency resources to all XR UEs to ensure timely packet delivery within their respective packet delay budgets (PDBs) . However, UE does not expect to be scheduled by the network during a pre-configured measurement gap (MG) for data transmission or reception. Even if a MG is not used, some of the cases where UE performs a measurement imposes scheduling restrictions. Such scheduling restrictions (with or without measurement gaps) cause interruptions to XR data transmissions, which may impact XR service performance in terms of system capacity. Consequently, effective mechanisms for measurement enhancement are necessary to improve system capacity and enable the support of applications demanding low-latency and high-data-rate transmissionsSUMMARY
[0005] The following summary is illustrative only and is not intended to be limiting in any way. That is, the following summary is provided to introduce concepts, highlights, benefits and advantages of the novel and non-obvious techniques described herein. Select implementations are further described below in the detailed description.

[0008] In another aspect, a method may involve an apparatus receiving a configuration for a configured measurement gap (MG) or effective measurement gap (EMG) for associated frequency carriers from a network node. The method may also involve the apparatus performing a gapless and interruption-free measurement for a carrier not associated with the configured MG or EMG.
[0009] In yet another aspect, a method may involve an apparatus searching at least one synchronization signal and physical broadcast channel block (SSB) for a first application on a first synchronization raster.

[0020] Detailed embodiments and implementations of the claimed subject matters are disclosed herein. However, it shall be understood that the disclosed embodiments and implementations are merely illustrative of the claimed subject matters which may be embodied in various forms. The present disclosure may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments and implementations set forth herein. Rather, these exemplary embodiments and implementations are provided so that description of the present disclosure is thorough and complete and will fully convey the scope of the present disclosure to those skilled in the art. In the description below, details of well-known features and techniques may be omitted to avoid unnecessarily obscuring the presented embodiments and implementations. Overview
[0021] Implementations in accordance with the present disclosure relate to various techniques, methods, schemes and / or solutions pertaining to measurement enhancements in mobile communications. According to the present disclosure, a number of possible solutions may be implemented separately or jointly. That is, although these possible solutions may be described below separately, two or more of these possible solutions may be implemented in one combination or another.
[0022] FIG. 1 illustrates an example scenario 100 of a communication environment in which various solutions and schemes in accordance with the present disclosure may be implemented. Scenario 100 involves a user equipment (UE) 110 in wireless communication with a wireless network (e.g., a 5G NR network) consisting of an access network 120 and a core network 130. The UE 110 may be a smart phone, a wearable device, an IoT device, and a tablet, etc. Alternatively, the UE 110 may be a notebook (NB) or personal computer (PC) inserted or installed with a data card which includes a modem and radio frequency (RF) transceiver (s) to provide the functionality of wireless communication. In 5G NR, the access network 120 is connected to the core network 130 by means of the NG interface, more specifically to a user plane function (UPF) by means of the NG user-plane part (NG-u) , and to a mobility management function (AMF) by means of the NG control-plane part (NG-c) . One BS (e.g., a next generation Node-B (gNB) ) can be connected to multiple UPFs / AMFs for the purpose of load sharing and redundancy. In addition, the core network may include other entities, such as session management function (SMF) and unified data management (UDM) , etc. The access network 120 may include multiple base stations (BSs) , such as the BS 121 and the BS 122, each of which may provide communication coverage for a geographic coverage area where communications with the UE 110 is supported.
[0023] In one embodiment, the wireless network in scenario 100 may support services that require low latency and high data rate transmissions, such as extended reality (XR) services. The UE 110 may periodically receive a protocol data unit (PDU) burst from a BS (e.g., the BS 121 or 122) . XR traffic is subject to a strict low latency requirement, measured in terms of packet delay budget (PDB) . This represents the maximum allowable delay for a packet to be transmitted from a BS to a UE. On the other hand, the UE 110 may receive a measurement gap (MG) configuration from a BS (e.g., the BS 121 or 122) and perform measurements accordingly. As shown in scenario 200 of FIG. 2, the UE 110 may perform the radio resource management (RRM) measurements on the occasions of the configured MGs 211, 213, 215, and 217. The UE 110 does not expect to be scheduled by the network during the MGs 211, 213, 215, and 217 for uplink / downlink data transmission. However, the PDU bursts 221, 223, 225, and 227 are transmitted from the BS. As the occasions of the XR data transmissions 231, 233, 235, and 237 overlap with the occasions of the configured MGs 211, 213, 215, and 217, respectively, the interruptions to XR data transmission may occur, negatively impacting XR service performance. To mitigate this, a restriction-free transmission and reception scheduling for high-priority traffic (e.g., XR traffic) is enabled based on a configuration for data transmission masks. Further, the RRM measurements are restricted outside of intended scheduling opportunities in time by effective measurement gaps (EMGs) .
[0024] FIG. 3A is a diagram depicting an example scenario of data transmission mask in accordance with implementations of the present disclosure. In scenario 300a, the network (e.g., the BS 121 or 122) may configure the UE 110 with one or more data transmission masks. A data transmission mask is a repeating or non-repeating pattern in time domain which spans a pre-defined duration. A data transmission mask configures or indicates on which time occasions the UE 110 is allowed or not allowed to perform measurements by causing data transmission interruptions and / or by utilizing measurement gaps (MGs) and / or causing any other scheduling restrictions. In other words, the data transmission mask configuration may override a synchronization signal and physical broadcast channel block (SSB) measurement timing configuration (SMTC) configuration and / or a MG configuration. In one embodiment, the data transmission mask includes an occasion frequency smaller than a frame rate, a data arrival success rate (e.g., 10 milliseconds (ms) ) , or a combination thereof.
[0025] The UE 110 may determine whether to perform a configured measurement based on whether an occasion associated with the configured measurement overlaps with the data transmission mask. For example, the UE 110 may drop / ignore an MG occasion if it is determined that the MG occasion overlaps with the data transmission mask, and perform a data transmission during such MG occasion. As shown in scenario 300a, the occasions indicated by white arrows do not overlap with the data transmission mask and the UE 110 may perform measurements during these MG occasions. However, as the occasions indicated by black arrows overlap with the data transmission mask, the UE 110 drops / ignores those MG occasions (i.e., no measurement is performed) and may utilize these occasions for data transmission without interruption. In another example, if the data transmission mask overlapped with an SSB burst occasion and partial of the SSBs in that SSB burst are not overlapped with the data transmission mask, then the UE 110 may perform measurements on that non-overlapped SSB (s) within the overlapped SSB burst.
[0026] In one embodiment, the network may configure the UE 110 with one or multiple data transmission mask patterns through a downlink control information (DCI) signaling, a radio resource control (RRC) signaling, or a medium access control (MAC) -control element (CE) signaling. The predefined pattern may be configured or activated / enabled based on a frame rate, a data rate, an occasion duration difference between patterns, or any combination of the foregoing factors. The data transmission masks shown in FIG. 3A may correspond to a predefined mask pattern selected by the network. For example, the network may select one of the predefined mask patterns and configure the UE 110 with the selected data transmission mask pattern. Alternatively, the data transmission masks may correspond to a predefined mask pattern selected by the UE 110. To be specific, the network may configure the UE 110 with multiple data transmission mask patterns. The UE 110 may select one of the configured mask patterns, and inform the network of the selected mask pattern via the DCI signaling, the RRC signaling, or the MAC-CE signaling.
[0027] In another embodiment, the data transmission masks may correspond to a mask pattern dynamically introduced by either the network or the UE 110 based on the data distribution of the specific application. If the UE 110 determines the mask pattern, it may inform the network of the determined mask pattern.
[0028] FIG. 3B is a diagram depicting an example scenario of EMG in accordance with implementations of the present disclosure. The EMGs are determined to restrict the RRM measurement outside of the intended scheduling opportunities in time. As shown in scenario 300b, the UE 110 may perform the measurement with MG on partial MG occasions or on a new different MG occasion outside the configured SMTC and / or MG patterns. The new resulting pattern of this MG is referred to as the EMG. For example, the UE 110 may receive one or more configurations for the data transmission masks, the MGs, and the SMTC windows, and determine the EMGs for performing the measurement based on at least one of the data transmission mask pattern, the MG pattern, and the SMTC pattern associated with the received configurations. The EMG pattern may follow a punctured MG pattern, the configured SMTC pattern and the data transmission mask pattern, where the UE 110 perform the measurements with MG occasions outside the data transmission mask pattern (as indicated by the white arrows) . In other words, the UE 110 will discard any MG occasion that overlaps (partially or fully) with the data transmission mask pattern. In another example, the EMG may be outside the configured MG pattern. The UE 110 may select an SSB occasion to perform measurements with the EMG that does not overlap with the data transmission mask.
[0029] In one embodiment, the network may enable or disable whether the UE 110 can follow EMG instead of MG patterns. For example, the UE 110 may receive an indication from the network, and determine whether to enable or disable the EMG based on the indication. In another embodiment, the UE 110 may enable, disable, or report to the network the need for a new EMG instead of MG patterns.
[0030] The present disclosure also proposes the concept of gapless and interruption-free (i.e., hidden interruption) measurements for inter-frequency intra-band measurements. The UE 110 may perform the measurements without introducing MGs and without disrupting data reception or transmission. Specifically, no interruption is caused for data within the data transmission mask. The UE 110 may perform an interruption-free RF retuning outside the data transmission mask. In another embodiment, the UE 110 may determine the hidden interruption (e.g., RF retuning) location, yet the hidden RF retuning occur outside the data transmission mask. In some embodiment, the UE 110 may report to the network the frequency carriers where uninterrupted measurements are possible. Also, the UE 110 may follow the SMTC for measurements or, alternatively, rely on the SSB pattern for measurement timing (i.e., ignoring the SMTC pattern) . In some scenarios, the network may configure the UE 110 on whether to measure with or without the hidden interruption for a given frequency carriers or bands.
[0031] Furthermore, the present disclosure proposes configuration of concurrent MGs for inter-frequency inter-band measurements with interruption free measurements for inter-frequency intra-band measurements. In one embodiment, the UE 110 may report to the network that there is no need for MGs or any interruption for measurements when an SSB is within an active bandwidth part (BWP) of the UE 110. Specifically, the UE 110 capable of supporting the data transmission mask may report to the network that an interruption-free RF retuning is needed for the inter-frequency intra-band measurement (s) . In some examples, the UE 110 may report to the network the need for MGs and / or the need for EMGs for the inter-frequency inter-band measurement (s) .
[0032] In another embodiment, the network may configure the UE 110 with MGs and / or EMGs for associated frequency carriers or bands. Such configuration may be based on a report from the UE 110, a decision made by the network regardless of the UE reporting, or the data transmission mask associated with a specific application. In this scenario, the network may configure the UE 110 to perform the gapless and interruption free measurements for the other carriers not associated with the configured EMG or MG.
[0033] In some embodiments, the UE 110 may search for at least one SSB for a first application on a first synchronization raster and for at least one SSB for a second application on a distinct second synchronization raster. In other words, SSB searches for different applications (or services) are conducted on their respective synchronization raster frequency locations. In one example, the first application may be an XR application, the network may transmit the SSBs in a synchronization raster frequency location dedicated for the XR application, and the UE 110 may follow the XR synchronization raster. In one example, the UE 110 may inform the network of whether it is capable of following the XR synchronization raster. The SSB (s) transmitted on the XR synchronization raster may have a periodicity of 30 frames per second (fps) , 60 fps, or 90 fps. Illustrative Implementations

[0037] In one aspect, each of the processor 412 and processor 422 may be implemented in the form of one or more single-core processors, one or more multi-core processors, or one or more CISC processors. That is, even though a singular term “a processor” is used herein to refer to processor 412 and processor 422, each of the processor 412 and processor 422 may include multiple processors in some implementations and a single processor in other implementations in accordance with the present disclosure.

Process 500 may be an example implementation of above scenarios / schemes, whether partially or completely, with respect to measurement enhancements in mobile communications. Process 500 may represent an aspect of implementation of features of communication apparatus 410. Process 500 may include one or more operations, actions, or functions as illustrated by one or more of blocks 510 and 520. Although illustrated as discrete blocks, various blocks of process 500 may be divided into additional blocks, combined into fewer blocks, or eliminated, depending on the desired implementation. Moreover, the blocks of process 500 may be executed in the order shown in FIG. 5 or, alternatively, in a different order. Process 500 may be implemented by communication apparatus 410 or any suitable UE (e.g., the UE 110) or machine type devices. Solely for illustrative purposes and without limitation, process 500 is described below in the context of communication apparatus 410 as a UE. Process 500 may begin at block 510.
[0042] At block 510, process 500 may involve processor 412 of communication apparatus 410 receiving, via transceiver 416, a first configuration for a data transmission mask from a network node (e.g., network apparatus 420) . Process 500 may proceed from block 510 to block 520.

Process 600 may be implemented by communication apparatus 410 or any suitable UE (e.g., the UE 110) or machine type devices. Solely for illustrative purposes and without limitation, process 600 is described below in the context of communication apparatus 410 as a UE. Process 600 may begin at block 610.
[0062] At block 610, process 600 may involve processor 412 of communication apparatus 410 receiving, via transceiver 416, a configuration for a configured MG or EMG for associated frequency carriers from a network node (e.g., network apparatus 420) .

[0063] At block 620, process 600 may involve processor 412 performing a gapless and interruption-free measurement for a carrier not associated with the configured MG or EMG.
[0064] In some implementations, the configuration is based on a report from the apparatus, a network decision, or a data transmission mask associated with a specific application.

[0067] At block 720, process 700 may involve processor 412 searching at least one SSB for a second application on a second synchronization raster, in which the second synchronization raster is different from the first synchronization raster.
[0068] In some implementations, the first application may include an XR application. Process 700 may involve processor 412 informing a network node of a capability of following the first synchronization raster.
[0069] In some implementations, the SSB transmitted on the first synchronization raster has a periodicity of 30 fps, 60 fps, or 90 fps. Additional Notes
[0070] The herein-described subject matter sometimes illustrates different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely examples, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively "associated" such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as "associated with" each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being "operably connected" , or "operably coupled" , to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being "operably couplable" , to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable and / or physically interacting components and / or wirelessly interactable and / or wirelessly interacting components and / or logically interacting and / or logically interactable components.
[0071] Further, with respect to the use of substantially any plural and / or singular terms herein, those having skill in the art can translate from the plural to the singular and / or from the singular to the plural as is appropriate to the context and / or application. The various singular / plural permutations may be expressly set forth herein for sake of clarity.
[0072] Moreover, it will be understood by those skilled in the art that, in general, terms used herein, and especially in the appended claims, e.g., bodies of the appended claims, are generally intended as “open” terms, e.g., the term “including” should be interpreted as “including but not limited to, ” the term “having” should be interpreted as “having at least, ” the term “includes” should be interpreted as “includes but is not limited to, ” etc. It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim recitation to implementations containing only one such recitation, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an, " e.g., “a” and / or “an” should be interpreted to mean “at least one” or “one or more; ” the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number, e.g., the bare recitation of "two recitations, " without other modifiers, means at least two recitations, or two or more recitations. Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc. ” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention, e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and / or A, B, and C together, etc. In those instances where a convention analogous to “at least one of A, B, or C, etc. ” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention, e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and / or A, B, and C together, etc. It will be further understood by those within the art that virtually any disjunctive word and / or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B. ”
