[0002] This disclosure is part of a non-provisional application claiming priority to U.S. Patent Application No. 63 / 579,303, filed August 29, 2023, the contents of which are incorporated herein by reference in their entirety. Technical Field

[0003] This disclosure generally relates to mobile communications, and more specifically, to group-based paging in mobile communications in connection with user equipment and network equipment. Background Technology

[0004] Unless otherwise stated herein, the methods described in this section are not prior art to the claims listed below, and are not admitted as prior art by virtue of their inclusion in this section.

[0005] In fifth-generation (5G) New Radio (NR) networks, a process called paging is used to locate the UE before an actual connection is established between the User Equipment (UE) and the base station. In most cases, paging occurs when the UE is in radio resource control (RRC) idle mode. This means the UE must monitor the network for any paging messages and expend energy to run this "monitoring" process. In RRC idle mode, the UE enters and remains in a sleep mode defined in the Discontinuous Receive (DRX) cycle. The UE periodically wakes up and monitors the Physical Downlink Control Channel (PDCCH) to check for the presence of paging messages. However, the current paging monitoring framework can lead to significant power consumption for the UE. Achieving energy efficiency optimization is a crucial issue in newly developed wireless communication systems. Therefore, appropriate solutions are needed to improve power consumption during paging. Summary of the Invention

[0006] The following summary is for illustrative purposes only and is not intended to be limiting in any way. That is, the following summary aims to introduce the concepts, highlights, benefits, and advantages of the novel and non-obvious techniques described herein. Selected embodiments will be further described in the detailed description below. Therefore, the following summary is not intended to identify the essential features of the claimed subject matter, nor is it intended to determine the scope of the claimed subject matter.

[0007] One objective of this disclosure is to propose a solution or scheme for addressing group-based paging problems related to user equipment (UE) and network equipment in mobile communications.

[0008] In one aspect, one method may involve a device receiving a paging indication from a network node. Another method may involve the device, upon being awakened by a paging indication, determining the start time of a monitoring window based on the time the paging indication was received. Yet another method may involve the device performing paging occasion (PO) monitoring within the monitoring window based on the start time.

[0009] In one aspect, an apparatus may include a transceiver that wirelessly communicates with a network node during operation. The apparatus may also include a processor communicatively connected to the transceiver. During operation, operations that the processor may perform include receiving a paging indication from the network node via the transceiver. Further operations that the processor may perform include determining a start time of a monitoring window based on the reception time of the paging indication if the apparatus is awakened by the paging indication. Further operations that the processor may perform include performing PO monitoring within the monitoring window according to the start time.

[0010] In another aspect, one approach might involve the network node sending a paging indication to the UE. Another approach might involve the network node sending a physical downlink control channel (PDCCH) to the UE within the PO monitoring window, where the paging indication carries the UE's wake-up indication. The start time of the PO monitoring window might be related to the time the paging indication is received.

[0020] This specification discloses detailed embodiments and implementations of the claimed subject matter. However, it should be understood that the disclosed embodiments and implementations are merely illustrative of the claimed subject matter and can be embodied in various forms. This disclosure can be embodied in many different forms and should not be construed as being limited to the exemplary embodiments and implementations set forth herein. Rather, these exemplary embodiments and implementations are intended to make the description of this disclosure thorough and complete, and to fully convey the scope of this disclosure to those skilled in the art. Details of well-known features and techniques may be omitted in the following description to avoid unnecessarily obscuring the presented embodiments and implementations.

[0021] Overview

[0022] The implementations disclosed herein relate to various technologies, methods, schemes, and / or solutions related to group-based paging in mobile communications, to achieve a better trade-off between user equipment (UE) power consumption and paging latency. According to this disclosure, multiple possible solutions can be implemented individually or in combination. That is, although these possible solutions may be described separately below, two or more of them can be implemented in one or another combination.

[0023] Figure 1An example scenario 100 of group-based paging is illustrated, in which various solutions and schemes according to this disclosure can be implemented. In scenario 100, the UE uses its ultra-low power radio / receiver (ULR) to monitor paging indications to check whether it has been instructed to wake up to receive a paging occasion (PO). If the UE is instructed to wake up to receive a PO, the UE determines the start time of the monitoring window based on the reception time of the paging indication. Subsequently, the UE uses its main radio / receiver (MR) to perform PO monitoring within the monitoring window according to the start time. In scenario 100, the paging indication may carry one or a combination of a wake-up indication and a public message. The wake-up indication is associated with the UE or UE group, and the public message may be a notification of system information updates or an emergency message, such as an earthquake and tsunami warning system (ETWS) message and a commercial mobile alert system (CMAS) message.

[0024] Specifically, upon receiving a paging indication, the UE first determines whether the paging indication carries a wake-up indication. If the paging indication carries a wake-up indication related to the UE, the UE activates MR and begins receiving signals / channels via MR within the monitoring window. The start time of the monitoring window is related to the reception time of the monitored paging indication. PO monitoring can also be related to the reception time of the monitored paging indication. PO monitoring can be aperiodic. For example, the monitoring window may start after a time offset following the receipt of the paging indication. The time offset and monitoring window length can be determined based on one or more configurations from the network. In scenario 100, the UE's MR remains in deep sleep mode (e.g., ultra-deep sleep mode) until it is activated for PO monitoring. On the other hand, if the paging indication does not carry any wake-up indication (e.g., only a public message), the MR remains in ultra-deep sleep mode, such as... Figure 2 Scene 200 is shown.

[0025] In one embodiment, the UE may expect to receive an aperiodic reference signal (RS) only when instructed to wake up to receive a PO, and the UE may perform a synchronization process (e.g., time and frequency synchronization process) based on the received aperiodic reference signal (RS) before performing PO monitoring.

[0026] To further reduce UE complexity and power consumption in paging indication monitoring, paging indications can be sequence-based, allowing processing via baseband signal processing (e.g., sequence matching) instead of a decoding process. The sequence can be an m-sequence, gold sequence, ZC sequence, or low-density power boosting (LDPB) sequence, but this disclosure is not limited to these. In this disclosure, UEs monitoring the same PO are further subgrouped to reduce false alarm rates. Figure 3 As shown, each paging indication 310 and 320 corresponds to two UE groups G1 and G2, and each G1 and G2 has N symbols to carry N bits, where 1 bit is used for 1 subgroup. Therefore, in scenario 300, the total number of subgroups is... When the wake-up indication of the paging indication is related to a subgroup of the UE, the UE is instructed to wake up.

[0027] To monitor paging indications, one or a combination of the following parameters is configured via higher-level signaling: paging indication periodicity, frequency resources (e.g., starting resource block and resource block number), sequence repetition count, subgroup number, subgroup bits to be read, sequence root for signal generation, and cyclic shift for signal generation. This configuration may be achieved through higher-level signaling, such as master information block (MIB), system information blocks (SIBx), or radio resource control (RRC) release messages. The UE may receive at least one of the above configurations for paging indication monitoring. If paging indication periodicity is not configured, the UE monitors paging indications with the default periodicity. If sequence repetition count is not configured, the UE receives paging indications with a default repetition count (e.g., 1 or a predetermined number greater than 1); otherwise, the signal is transmitted in duplicate according to the sequence repetition count. If subgroup number is not configured, the UE assumes the default subgroup number for the paging indication.

[0028] In one embodiment, the UE determines the monitoring time for the paging indication based on one or a combination of the user equipment group identity (UEID), the paging indication periodicity, and the monitoring time slot number within the time period, and then performs paging indication monitoring at the monitoring time slot. For example, the monitoring time slot can be determined by the following relationship: UEID mod paging indication periodicity in slot In one embodiment, if the paging indication carries a wake-up indication, the user equipment (UE) performs a subgroup mapping between the wake-up indication and the UE's subgroup number, and determines that the UE was woken up by the paging indication if the specific subgroup number indicated by the wake-up indication corresponds to the device's subgroup number. In one embodiment, the subgroup mapping may be explicitly indicated by the network. For example, suppose an RRC release message indicates that the UE is in subgroup 2, and the total number of subgroups is 8. If bit '010' (3 bits total for 8 subgroups) or the second bit of the paging indication is '1' (8 bits total for 8 subgroups) is received, the UE wakes up. In another embodiment, the subgroup mapping is derived based on the UEID and the total number of subgroups. For example, if the UEID mod total number of subgroups equals 2, the UE wakes up if bit '010' (3 bits total for 8 subgroups) or the second bit of the paging indication is '1' (8 bits total for 8 subgroups) is received. In one embodiment, to save bits in the wake-up indication, a specific bit pattern (e.g., all '1's or all '0's) can be used to indicate that all UEs are woken up for PO monitoring.

[0029] In the above embodiments, the UE uses its Low Power Receiver (ULR) to monitor the paging indication and its Main Receiver (MR) to monitor the Point of Purchase (PO). However, this disclosure is not limited to this. As described in Scenario 400, the UE can simultaneously monitor both the paging indication and the PO using its MR. Sequence-based paging indications are used so that the UE can process the paging indication through simple baseband signal processing. It should be noted that the scheme proposed in this disclosure is not limited to a dual radio layer architecture (e.g., MR and ULR). In some implementations, it is also applicable to a single radio layer or a single transmitter (TX) / receiver (RX).

[0030] It is important to note that in this disclosure, PO refers to a non-periodic PO rather than a periodic PO. Specifically, PO does not occur periodically, and one or a combination of the start time and length of the monitoring window is configured via higher-layer signaling (e.g., MIB, SIBx, or RRC release messages) so that the UE can perform PO monitoring within the monitoring window based on the start time.

Figure 5 This is not shown in the text or described below, in order to keep it concise.

[0034] Network device 520 may be part of a network device, which may be a network node such as a satellite, base station, small cell, router, or gateway.

[0035] In one aspect, each of processors 512 and 522 may be implemented as one or more single-core processors, one or more multi-core processors, or one or more Complex Instruction Set Computer (CISC) processors.

Process 600 can be an example implementation of the above-described scenario / scheme, whether partial or complete, involving group-based paging in mobile communications. Process 600 can represent one aspect of the functional implementation of communication device 510.

[0057] Additional notes

[0058] The topics described herein sometimes demonstrate different components contained within or connected to different components. It should be understood that the architectures depicted are merely examples, and many other architectures can actually be implemented to achieve the same functionality. Conceptually, any arrangement of components to achieve the same functionality is effectively “associated” to achieve the desired function. Therefore, any two components combined in this document to achieve a specific function can be considered “associated” with each other to achieve the desired function, regardless of the architecture or intermediate components. Similarly, any two such associated components can also be considered “operably connected” or “operably coupled” to achieve the desired function, and any two components that can be suchly associated can also be considered “operably coupled” to achieve the desired function. Specific examples of operational coupling include, but are not limited to, physically matable and / or physically interactive components and / or wirelessly interactive and / or logically interactive components.

[0059] Furthermore, regarding the use of almost all plural and / or singular terms in this article, those with technical skills may appropriately translate from plural to singular and / or from singular to plural depending on the context and / or application. Various singular / plural arrangements can be explicitly listed here for clarity.

[0060] Furthermore, those skilled in the art will understand that, in general, the terms used herein, particularly in appended claims, such as the body of an appended claim, are often considered "open" terms. For example, the word "comprising" should be interpreted as "comprising but not limited to," the word "having" should be interpreted as "having at least," and the word "including" should be interpreted as "including but not limited to," etc. Those skilled in the art will also understand that if a particular quantity is intended to be used in an introduced claim statement, that intention will be explicitly stated in the claim; if no such statement is given, then no such intention exists. For example, to aid understanding, the following appended claims may contain the use of the introductory phrases "at least one" and "one or more" to introduce the claim statement. However, the use of these phrases should not be construed as implying that a claim statement introduced by the indefinite article "a" or "an" limits any particular claim containing such an introductory claim statement to containing only one such statement, even if the same claim includes the introductory phrase "one or more" or "at least one" and indefinite articles such as "a" or "an," for example, "a" and / or "an" should be interpreted as "at least one" or "one or more"; the same applies to the use of definite articles used to introduce claim statements. Furthermore, even when a specific number of claims is explicitly stated, those skilled in the art will recognize that such a statement should be interpreted as at least the stated number. For example, the single statement "two statements," without any other modifier, means at least two statements, or two or more statements. Additionally, when using conventions such as "at least one A, B, and C, etc.", generally, this structure is interpreted in a way that is understood by those skilled in the art. For example, "a system having at least one A, B, and C" includes, but is not limited to, systems having only A, only B, only C, A and B together, A and C together, B and C together, and / or systems having A, B, and C together, etc. Similarly, when using conventions such as "at least one A, B, or C, etc.", generally, this structure is interpreted in a way that is understood by those skilled in the art. For example, "a system having at least one A, B, or C" includes, but is not limited to, systems having only A, only B, only C, A and B together, A and C together, B and C together, and / or systems having A, B, and C together, etc. Those skilled in the art will also understand that virtually any extractive term and / or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to include the possibility of containing one, any, or both terms. For example, the phrase “A or B” will be understood to include the possibility of “A” or “B” or “A and B”.
