METHODS AND APPARATUS FOR MONITORING STATE SWITCH 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 / 746, 292, filed 17 January 2025, the content of which is herein incorporated by reference in its entirety.TECHNICAL FIELD
[0002] The present disclosure is generally related to mobile communications and, more particularly, to monitoring state switch with respect to an apparatus and a network node 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] Wireless communication systems may be widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may use multiple-access technologies capable of supporting communication with multiple users by sharing available system resources. Examples of such multiple-access technologies may include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, and time division synchronous code division multiple access (TD-SCDMA) systems.
[0005] In communication technologies, the discontinuous reception (DRX) may be effective only when the DRX aligns with the precise timing of data bursts (i.e., the apparatus may be woken up to monitor data) . That is, when the DRX does not align with the timing of data bursts, additional power consumption may be generated.
[0006] Accordingly, how to efficiently perform monitoring becomes an important issue for the newly developed wireless communication network. Therefore, there is a need to provide proper schemes for the monitoring state switch to reduce the power consumption.SUMMARY
[0007] 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. Thus, the following summary is not intended to identify essential features of the claimed subject matter, nor is it intended for use in determining the scope of the claimed subject matter.
[0008] One objective of the present disclosure is to propose schemes, concepts, designs, systems, methods, and apparatus pertaining to monitoring state switch with respect to an apparatus and a network node in mobile communications. It is believed that the above-described issue would be avoided or otherwise alleviated by implementing one or more of the proposed schemes described herein.
[0009] In one aspect, a method may involve an apparatus receiving a configuration for a plurality of monitoring states from a network node. The method may also involve the apparatus monitoring a switch indication in a first monitoring state according to the configuration. The method may further involve the apparatus switching to a second monitoring state in an event that the switch indication is monitored in the first monitoring state.
[0010] In another aspect, a method may involve a network node transmitting a configuration for a plurality of monitoring states to a user equipment (UE) . The method may also involve the network node transmitting a switch indication to the UE according to the configuration to indicate the UE to switch from a first monitoring state to a second monitoring state.
[0011] It is noteworthy that, although description provided herein may be in the context of certain radio access technologies, networks and network topologies such as 5th Generation System (5GS) and 4G EPS mobile networking, the proposed concepts, schemes and any variation (s) / derivative (s) thereof may be implemented in, for and by other types of wireless and wired communication technologies, networks and network topologies such as, for example and without limitation, Ethernet, Universal Terrestrial Radio Access Network (UTRAN) , E-UTRAN, Global System for Mobile communications (GSM) , General Packet Radio Service (GPRS) / Enhanced Data rates for Global Evolution (EDGE) Radio Access Network (GERAN) , Long-Term Evolution (LTE) , LTE-Advanced, LTE-Advanced Pro, IoT, Industrial IoT (IIoT) , Narrow Band Internet of Things (NB-IoT) , 6th Generation (6G) , and any future-developed networking technologies.

[0024] 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
[0025] Implementations in accordance with the present disclosure relate to various techniques, methods, schemes, and / or solutions pertaining to monitoring state switch with respect to user equipment and network apparatus 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.
[0026] 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 UE 110 in wireless communication with a network 120 (e.g., a wireless network including an NTN and a TN) via a terrestrial network node 125 (e.g., an evolved Node-B (eNB) , a Next Generation Node-B (gNB) , or a transmission / reception point (TRP) ) and / or a non-terrestrial network node 128 (e.g., a satellite) . For example, the terrestrial network node 125 and / or the non-terrestrial network node 128 may form a non-terrestrial network (NTN) serving cell for wireless communication with the UE 110. In some implementations, the UE 110 may be an IoT device such as an NB-IoT UE or an enhanced machine-type communication (eMTC) UE (e.g., a bandwidth reduced low complexity (BL) UE or a coverage enhancement (CE) UE) . In such a communication environment, the UE 110, the network 120, the terrestrial network node 125, and the non-terrestrial network node 128 may implement various schemes pertaining to improved monitoring state switch procedure in accordance with the present disclosure, as described below. It is noteworthy that, while the various proposed schemes may be individually or separately described below, in actual implementations, some or all of the proposed schemes may be utilized or otherwise implemented jointly. Of course, each of the proposed schemes may be utilized or otherwise implemented individually or separately.
[0027] According to the implementations of the present disclosure, an apparatus (e.g., UE 110) may receive a configuration for a plurality of monitoring states from a network node (e.g., terrestrial network node 125) . Then, the apparatus may monitor a switch indication in a first monitoring state (e.g., a default monitoring state or a searching space set group 0 (SSSG0) state shown in FIG. 2) according to the configuration. In addition, the apparatus may switch to a second monitoring state (e.g., a non-default monitoring state or an SSSG1 state shown in FIG. 2) in an event that the switch indication is monitored in the first monitoring state.
[0028] According to the implementations of the present disclosure, the configuration may comprise at least one of a timer, an identification (ID) information of each monitoring state, a resource block (RB) -level offset, a monitoring periodicity, a maximum repetition number, an indication type (e.g., codepoint or bitmap) , a target SSSG (or a target monitoring state) (i.e., the SSSG which the apparatus switches to) , an application delay (e.g., the application delay for switching the current monitoring state to the target monitoring sate) , a cyclic shift, and a sequence root.
[0029] In an implementation, in an event that the timer configured in the configuration expires, the apparatus may switch to a default monitoring state. In an implementation, the timer may be common to all monitoring states. In addition, in an implementation, in an event that the apparatus receives the switch indication from the network node, the timer may be reset.
[0030] In an implementation, each monitoring state may be associated with different IDs (e.g., SSSG IDs) . For example, the first monitoring state may be associated with SSSG0, and the second monitoring state may be associated with SSSG1. In addition, in an implementation, in an event that an ID of the monitoring state is a default value (e.g., 0 or SSSG0) , the monitoring state may be a default monitoring state.
[0031] According to the implementations of the present disclosure, the first monitoring state may be associated with a lower-power receiver of the apparatus and may consume less power of the apparatus, and the second monitoring state may be associated with a main receiver of the apparatus and may consume more power of the apparatus.
[0032] According to the implementations of the present disclosure, the switch indication may comprise a sequence-based switch indication or a downlink control information (DCI) -based switch indication. In an implementation, the sequence-based switch indication may be monitored in the first monitoring state, and the DCI-based switch indication and a physical downlink control channel (PDCCH) may be monitored in the second monitoring state. In addition, in an implementation, the low-power receiver may be configured to receive the sequence-based switch indication from the network node, and the main receiver may be configured to receive the DCI-based switch indication from the network node. In an example, in an event that the apparatus receives the sequence-based switch indication from the network node through the low-power receiver, the apparatus may switch from the first monitoring state to the second monitoring state. In another example, in an event that the apparatus receives the DCI-based switch indication from the network node through the main receiver, the apparatus may switch from the second monitoring state to the first monitoring state. In another example, in an event that a timer for switching from the second monitoring state to the first monitoring state expires, the apparatus may switch from the second monitoring state to the first monitoring state.
[0033] FIG. 2 illustrates an example scenario 200 for an SSSG switch (i.e., monitoring state switch) in accordance with implementations of the present disclosure. Scenario 200 involves an apparatus (e.g., UE) and a network node (e.g., (macro / micro) base stations, transmission-reception points (TRPs) in serving cell and in another cell (e.g., serving TRP and another TRP in the serving cell, and another cell in another cell) ) of a wireless network (e.g., an LTE network, a 5G / NR network, an IoT network, or a 6G network) . Referring to FIG. 2, in an event that the apparatus receives the sequence-based switch indication from the network node, the apparatus may switch from the SSSG0 state (e.g., first monitoring state or default monitoring state) to the SSSG1 state (e.g., the second monitoring state or non-default monitoring state) . In an event that the apparatus receives the DCI-based switch indication from the network node, or the timer for switching from the second monitoring state to the first monitoring state expires, the apparatus may switch from the SSSG1 state (e.g., the second monitoring state or non-default monitoring state) to the SSSG0 state (e.g., first monitoring state or default monitoring state) .
[0034] According to the implementations of the present disclosure, an application delay may be required for switching from one monitoring state to another monitoring state. The application delay indicated by the network node may impact the performance of the apparatus. In an event that the application delay is too short, the UE may not enter into a deep sleep. In an event that the application delay is too long, the UE cannot be scheduled appropriately. In an implementation, different traffic services may be configured with different application delays. For example, for sensitive traffic service (e.g., voice over Internet Protocol (VoIP) or extended reality (XR) ) , a shorter application delay may be configured. In another example, for non-sensitive traffic service (e.g., file transfer protocol (FTP) or IP multimedia (IM) ) , a longer application delay may be configured.
[0035] FIG. 3 illustrates an example scenario 300 for an application delay in accordance with implementations of the present disclosure. Referring to FIG. 3, in an event that the apparatus switches from the monitoring state associated with the low-power receiver to the monitoring state associated with the main receiver, the apparatus may wait for an application delay to start / effect the state transition.
[0036] According to an implementation for application delay of the present disclosure, the apparatus may observe the traffic characteristics for a period of time (e.g., a specified duration) to determine an application delay. Then, the apparatus may transmit an application delay report to the network node according to the determined application delay. That is, the apparatus may report the suggested application delay to the network node. In the implementation, the period of time for observation may be configured through the radio resource control (RRC) . In addition, in the implementation, the observation process may be enhanced with an artificial intelligence (AI) technology. In the implementation, the application delay report transmission can be requested by the network node or triggered by the apparatus. In the implementation, the application delay may be maintained until a timer expires or until the application delay is updated. Specifically, the network node may update the application delay (or monitor occasion (MO) ) according to the application delay report from the apparatus. The updated application delay may be transmitted to the apparatus through layer 1 (L1) indicators, such as DCI or medium access control (MAC) -control element (MAC-CE) . The (updated) application delay value (or MO) may be maintained until a configured timer expires. In an event that the timer is not configured, the (updated) application delay value may be maintained until the (updated) application delay is updated by the network node again.
[0037] FIG. 4 illustrates an example scenario 400 for an application delay configuration in accordance with implementations of the present disclosure. Referring to FIG. 4, the apparatus may observe the traffic characteristics for a period of time (e.g., a specified duration) to determine an application delay. In an event that the low-power receiver of the apparatus receives the lower-power receiver (LR) -wake-up signal (LR-WUS) to trigger the main receiver of the apparatus, the apparatus may wake up the main receiver after an application delay. The apparatus may transmit an application delay report to the network node via the main receiver to report a suggested application delay. The network node may update the application delay according to the application delay report from the apparatus. When the main receiver is awakened again, the network node may transmit the updated application delay to the apparatus. Then, when the apparatus receives the LR-WUS to trigger the main receiver again, the apparatus may wake up the main receiver after the updated application delay.
[0038] According to another implementation for the application delay of the present disclosure, the apparatus may determine more than one application delays according to the switch indication. Different monitoring states may be associated with different application delays. For example, more than two SSSGs may be configured. One SSSG (e.g., SSSG0) with an SSSG ID equal to a default value (e.g., 0) may be a default SSSG. Other SSSGs (e.g., SSSG1 and SSSG2) with SSSG IDs not equal to the default value may be switched to the default SSSG in an event that the SSSG timer expires.
[0039] FIG. 5 illustrates another example scenario 500 for an application delay configuration in accordance with implementations of the present disclosure. Referring to FIG. 5, in an event that the low-power receiver of the apparatus receives the SSSG switch indication from the network node in the default SSSG (e.g., SSSG0) to trigger the main receiver of the apparatus, the apparatus may wake up the main receiver after an application delay corresponding to the default SSSG (e.g., SSSG0) . In addition, the main receiver of the apparatus may receive the SSSG switch indication to switch to the non-default SSSG (e.g., SSSG 1) from the network node. In an event that the low-power receiver of the apparatus receives the SSSG switch indication in the non-default SSSG (e.g., SSSG1) to trigger the main receiver of the apparatus, the apparatus may wake up the main receiver after an application delay corresponding to the non-default SSSG (e.g., SSSG1) . The application delay of the SSSG1 may be shorter than the application delay of the SSSG0 for the sensitive traffic. The SSSGs with SSSG IDs (e.g., SSSG1 and SSSG2) not equal to the SSSG ID of the default SSSG (e.g., SSSG0) may be switched to the default SSSG in an event that an SSSG timer expires.
[0040] According to the implementations of the present disclosure, the sequence-based switch indication may comprise a codepoint or a bitmap.
[0041] A sequence (e.g., a low-density power boosted (LDPB) sequence or a cyclic shifted sequence may be used for indicating the monitoring state switch (e.g., SSSG switch) . The sequence may be generated according to the following formulas: dWUS (n) =βWUSxi, j (n) xi, j (n) = yi ( (n -x * j) mod133) 0≤n<133 0≤l<12 i∈{0} ,
[0042] In some cases, (1) dWUS (n) may be a value of (n+1) th position of the cyclic shifted sequence, (2) n may be a sequence length, (3) l may be a number of RBs used for the WUS, (4) may be a set of position indexes of the plurality of non-zero values of (i+1) th root sequence, (5) x may be cyclic shift offset (CFO) , and the root sequence may be configurable, e.g.,
[0043] In some implementations, the cyclic shifted sequence may be masked to account for phase rotation with respect to the synchronization signal. In particular, to optimize the time domain peak-to-average power ratio (PAPR) with respect to the synchronization signal encoded by the cyclic shifted sequence, the cyclic shifted sequence may be masked before being used to encode the synchronization signal. FIG. 6 illustrates another example scenario 600 for a sequence configuration in accordance with implementations of the present disclosure. Referring to FIG. 6, the values of i and l for a PAPR scrambling sequence for non-zero positions may be set in the table.
[0044] According to the implementations of the present disclosure, the codepoint-based switch indication or the bitmap-based switch indication may be configured by a UE-specific RRC signaling. The apparatus in a subgroup (SG) may be configured with the same sequence, e.g., the same root, cyclic shift, and SG index. The maximum number of sequence repetitions may be configured.
[0045] In some implementations for the codepoint-based switch indication, the apparatus may use the assigned sequence corresponding to the SG index for detection. In an implementation, only one SG can be woken up on the occasion. In another implementation, if more than two SGs need to wake up, a specific sequence may be designed to wake up these SGs, e.g., sequence 16 shown in FIG. 7.
[0046] FIG. 7 illustrates another example scenario 700 for a codepoint in accordance with implementations of the present disclosure. Referring to FIG. 7, the codepoint may comprise sequences 1~16. The sequence 1 may correspond to SG1. The sequence 2 may correspond to SG2. The sequence 3 may correspond to SG3. The sequence 4 may correspond to SG4. The sequence 5 may correspond to SG5. The sequence 6 may correspond to SG6. The sequence 7 may correspond to SG7. The sequence 8 may correspond to SG8. The sequence 9 may correspond to SG9. The sequence 10 may correspond to SG10. The sequence 11 may correspond to SG11. The sequence 12 may correspond to SG12. The sequence 13 may correspond to SG13. The sequence 14 may correspond to SG14. The sequence 15 may correspond to SG15. The sequence 16 may correspond to more than two SGs.
[0047] In some implementations for the bitmap-based switch indication, the apparatus may detect the sequence based on the configured root and cyclic shift. The apparatus may determine its switch indication (e.g., SSSG switch indication) via the assigned bit position carried by the detected sequence. In an implementation, multiple SGs can be woken up on one occasion.
[0048] FIG. 8 illustrates another example scenario 800 for a bitmap in accordance with implementations of the present disclosure. Referring to FIG. 8, the bitmap may comprise sequences 1~16. For sequence 1, no SGs may be woken up. For sequence 2, SG4 may be woken up. For sequence 3, SG3 may be woken up. For sequence 4, SG3 and SG4 may be woken up. For sequence 5, SG2 may be woken up. For sequence 6, SG2 and SG4 may be woken up. For sequence 7, SG2 and SG3 may be woken up. For sequence 8, SG2, SG3, and SG4 may be woken up. For sequence 9, SG1 may be woken up. For sequence 10, SG1 and SG4 may be woken up. For sequence 11, SG1 and SG3 may be woken up. For sequence 12, SG1, SG3, and SG4 may be woken up. For sequence 13, SG1 and SG2 may be woken up. For sequence 14, SG1, SG2, and SG4 may be woken up. For sequence 15, SG1, SG2, and SG3 may be woken up. For sequence 16, SG1, SG2, SG3, and SG4 may be woken up.
[0049] According to the implementations of the present disclosure, the DCI-based switch indication may be carried by a scheduling DCI or a non-scheduling DCI. In an implementation, the bit number in the DCI field may be equal to where NSSSG is the number of configured SSSG. In an implementation, the DCI-based switch indication may indicate the apparatus to switch to an SSSG with an SSSG ID equal to the SSSG switch indication. In an event that the SSSG switch indication is equal to the current SSSG that the apparatus is monitoring, the apparatus may not change its SSSG.
[0050] In an implementation, the scheduling DCI may be used for the monitoring state switch (or monitor group switch) of the main receiver (MR) . In an example, the scheduling DCI may comprise 1 bit in an event that only one low-power (LR) -monitoring state (or LR-monitor group) (e.g., SSSG0 of FIG. 5) is configured, e.g., “0” may indicate a switch to the default LR-monitoring state (or monitor group) , and “1” may indicate the apparatus to stay in the same MR-monitoring state (or monitor group) . In another example, the scheduling DCI may comprise 2 bits in an event that two low-power-monitor groups (e.g., SSSG0 and SSSG1 of FIG. 5) are configured, e.g., “00” may indicate a switch to the default LR-monitoring state (or monitor group) , “01” may indicate the apparatus to stay in the same MR-monitoring state (or monitor group) , and “10” may indicate a switch to another LR-monitoring state (or monitor group) .
[0051] In an implementation, the non-scheduling DCI may be used for the monitoring state switch (or monitor group switch) of the MR. The non-scheduling DCI may comprise 1 bit. For example, “0” may indicate a switch to the default LR-monitoring state (or monitor group) , and “1” may indicate the apparatus to stay in the same MR-monitoring state (or monitor group) . In another example, the non-scheduling DCI may comprise 2 bits. For example, “00” may indicate a switch to the default LR-monitoring state (or monitor group) , “01” may indicate the apparatus to stay in the same MR-monitoring state (or monitor group) , and “10” may indicate a switch to another LR-monitoring state (or monitor group) .

[0055] In one aspect, each of processor 912 and processor 922 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 “aprocessor” is used herein to refer to processor 912 and processor 922, each of processor 912 and processor 922 may include multiple processors in some implementations and a single processor in other implementations in accordance with the present disclosure.

[0084] 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.
[0085] 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.
[0086] 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. ”
