Abstract

A wireless communication method is disclosed. The method comprises: receiving, by a wireless communication terminal from a wireless communication node, one or more wake-up signals for wake-up; and monitoring, by the wireless communication terminal, one or more paging early indications (PEIs), paging occasions (PO) or physical downlink control channels (PDCCHs) associated with the one or more wake-up signals.

Description

[0001] This document is generally aimed at wireless communication, and specifically at fifth-generation (5G) or sixth-generation (6G) communication.

[0002] 5G systems are designed and developed for both mobile phones and vertical use cases. Besides latency, reliability, and availability, user equipment (UE) energy efficiency is also crucial for 5G. Currently, 5G devices may require charging weekly or daily, depending on individual usage time. Generally, 5G devices consume tens of milliwatts in Radio Resource Control (RRC) idle / inactive mode and hundreds of milliwatts in RRC connected mode. Designs that extend battery life are essential for improving energy efficiency and a better user experience.

[0003] Energy efficiency is critical for UEs without a continuous power source, such as those using small rechargeable batteries and single coin cells. In vertical use cases, sensors and actuators are widely deployed for monitoring, measurement, charging, and more. Generally, their batteries are non-rechargeable and expected to last for several years. Wearable devices include smartwatches, rings, electronic health-related devices, and medical monitoring devices. Maintaining power for 1-2 weeks as needed with typical battery capacities is challenging.

[0004] Power consumption depends on the configured wake-up cycle length (e.g., paging cycle). To meet the aforementioned battery life requirements, it is anticipated that extended discontinuous reception (eDRX) cycles with large values ​​will be used, resulting in high latency, which is unsuitable for services requiring both long battery life and low latency. For example, in fire detection and suppression use cases, fireproof louvers should be closed, and fire sprinklers should be activated by actuators within 1 to 2 seconds after a fire is detected by the sensor. Long eDRX cycles cannot meet latency requirements. eDRX is unsuitable for latency-critical use cases. Therefore, it is necessary to investigate an ultra-low power mechanism capable of supporting low latency (e.g., below eDRX latency).

[0100] In some embodiments, the UE needs to be periodically woken up once in each discontinuous receive DRX cycle, which dominates power consumption during periods without signaling or data traffic. Power consumption can be reduced if the UE can be woken up only when triggered (e.g., by paging). In some embodiments, this can be achieved by using a wake-up signal to trigger the main radio and a separate receiver, which has the ability to detect the wake-up signal at low power. The main radio is used for data transmission and reception and can be turned off or set to deep sleep unless enabled.

[0101] Some embodiments of this disclosure focus on low-power wake-up signals (WUS) / wake-up receivers (WUR) for power-sensitive, small form factor devices, including Internet of Things (IoT) use cases such as industrial sensors and controllers and wearable devices.

[0102] Many aspects of this disclosure are provided in the following paragraphs, but the disclosure is not limited thereto. Furthermore, the different aspects described below may be combined, unless otherwise expressly stated.

[0103] Aspect 1:

[0104] In some embodiments, if the UE enters a sleep mode, the UE can monitor LP-WUS and the UE can be woken up by LP-WUS.

[0105] In some embodiments, the UE can monitor LP-WUS during a specific DRX inactivity period.

[0106] In some embodiments, the UE can continuously monitor LP-WUS during DRX inactivity periods.

[0107] In some embodiments, during DRX inactivity periods, the UE may periodically monitor LP-WUS, and the period and start time of LP-WUS are configured by RRC messages or SIB (System Information Block).

[0108] In some embodiments, the LP-WUS may carry a sub-packet identifier (ID) indicating which sub-packet is being woken up, or whether an enable duration timer has been started. If so, the UE with the same sub-packet is woken up.

[0109] In some embodiments, if cell DTX is enabled, the UE can enter sleep mode and stop receiving during the cell DTX inactive period. During the cell DTX inactive period, the UE can monitor LP-WUS.

[0110] In some embodiments, the UE can continuously monitor LP-WUS during the cell DTX inactive period.

[0111] In some embodiments, during the cell DTX inactive period, the UE may periodically monitor LP-WUS, the period and start time of which are configured by RRC messages or SIB.

[0112] In some embodiments, during the cell DTX inactive period, the UE can monitor LP-WUS at a time having a certain offset before the end time of the cell DTX inactive period or the start time of the cell DTX active period. This offset is configured by an RRC message or SIB.

[0113] In some embodiments, during the cell DTX inactive period, the UE may monitor LP-WUS for a certain duration. This duration is configured by the RRC message or SIB.

[0114] In some embodiments, the LP-WUS may carry an indication of whether the UE has been woken up, or whether the cell DTX enable duration timer has been started. If so, the UE is woken up.

[0115] In some embodiments, if cell DRX is enabled, the UE can enter sleep mode and stop transmitting during cell DRX inactivity periods. The UE can be woken up by LP-WUS.

[0116] In some embodiments, the LP-WUS may carry an indication of whether the UE has been woken up, or whether the cell DRX enable duration timer has been started. If so, the UE is woken up.

[0117] In some embodiments, the UE is woken up if it receives LP-WUS.

[0118] After the UE is woken up, the UE can consider the configured SPS (semi-persistent scheduling) timing to be valid and receive the SPS message.

[0119] After the UE is woken up, the UE can measure the SSB (Synchronization Signal / Physical Broadcast Channel Block) and CSI-RS (Channel State Information Reference Signal).

[0120] After the UE is woken up, the UE can monitor the PDCCH (Physical Downlink Control Channel) or receive the PDSCH (Physical Downlink Shared Channel).

[0121] After the UE is woken up, it can start an enable duration timer. During the enable duration timer, the UE can monitor the PDCCH.

[0122] In some embodiments, the start time of the enabled duration timer can be shifted to an earlier time with a certain offset. If the UE receives LP-WUS at time X, the start time of the enabled duration timer is configured to be time Y, the start time of the enabled duration timer is shifted to time X+Z, the offset is YXZ, and the UE starts the enabled duration timer at time X+Z. The gNB can configure the value of the offset or time Z (see [link]). Figure 1 ).

[0123] In some embodiments, the length of the enable duration timer is extended by a certain offset. If the UE receives LP-WUS at time X, and the configured enable duration timer length is set to time period Y, then the enable duration timer length is extended to Y + offset, where offset = YXZ, and the UE starts the enable duration timer at time X + Z. The gNB can configure the offset or the value of time Z (see [link to gNB]). Figure 2 ).

[0124] After the UE is woken up, it can start a timer, which can be a DRX inactive timer or another timer. During the timer's operation, the UE can monitor the PDCCH.

[0125] In some embodiments, the start time of the timer is determined by an offset. If the UE receives LP-WUS at time X, and the start time of the timer is configured to be time X + offset, then the UE starts the timer at X + offset. The gNB can configure the value of the offset.

[0126] In some embodiments, the length of the timer is determined by a length parameter, and the gNB can configure the value of this length parameter.

[0127] In some embodiments, during timer operation, if the UE detects a PDCCH and the received PDCCH indicates a new UL (uplink) or DL ​​(downlink) transmission, the UE may start a DRX inactivity timer. In some embodiments, if the timer expires, the UE stops monitoring the PDCCH.

[0128] After the UE is woken up, the UE can start the cell DTX start duration timer.

[0129] In some embodiments, the start time of the cell DTX enable duration timer can be shifted to an earlier time with a certain offset. If the UE receives LP-WUS at time X, the start time of the cell DTX enable duration timer is configured to be time Y, the start time of the cell DTX enable duration timer is shifted to time X+Z, the offset is YXZ, and the UE starts the cell DTX enable duration timer at time X+Z. The gNB can configure the value of the offset or time Z.

[0130] In some embodiments, the length of the cell DTX enable duration timer is extended by a certain offset. If the UE receives LP-WUS at time X, and the configured cell DTX enable duration timer length is set to time Y, then the cell DTX enable duration timer length is extended to Y + offset, where offset = YXZ, and the UE starts the cell DTX enable duration timer at time X+Z. The gNB can configure the value of the offset or time Z.

[0131] After the UE is woken up, the UE can start the cell DRX start duration timer.

[0132] In some embodiments, the start time of the cell DRX enable duration timer can be shifted to an earlier time with a certain offset. If the UE receives LP-WUS at time X, the start time of the cell DRX enable duration timer is configured to be time Y, the start time of the cell DRX enable duration timer is shifted to time X+Z, the offset is YXZ, and the UE starts the cell DRX enable duration timer at time X+Z. The gNB can configure the value of the offset or time Z.

[0133] In some embodiments, the length of the cell DRX enable duration timer is extended by a certain offset. If the UE receives LP-WUS at time X, and the configured cell DRX enable duration timer length is set to time Y, then the cell DRX enable duration timer length is extended to Y + offset, where offset = Y + Z, and the UE starts the cell DRX enable duration timer at time X + Z. The gNB can configure the value of the offset or time Z.

[0134] After the UE is woken up, the UE can assume that the configured CG (configured authorization) timing is valid and send an SPS (semi-persistent scheduling) message.

[0135] After the UE is woken up, the UE can consider the SR (Schedule Request) timing to be valid and send the SR.

[0136] After the UE is woken up, the UE can consider the PUCCH timing to be valid and send the PUCCH (Physical Uplink Control Channel).

[0137] After the UE is woken up, the UE can consider the PRACH (Physical Random Access Channel) timing to be valid and send the PRACH.

[0138] After the UE is woken up, the UE can send PUSCH (Physical Uplink Shared Channel).

[0139] Aspect 2

[0140] In some embodiments, the gNB can configure or broadcast the relationship between LP-WUS and PEI (Paging Early Indication).

[0141] In some embodiments, the gNB can configure or broadcast the number of PEIs corresponding to the same LP-WUS. In other words, the LP-WUS can wake up UEs corresponding to multiple PEIs. UEs corresponding to multiple PEIs can monitor the same LP-WUS.

[0142] In some embodiments, the gNB can configure or broadcast a time offset between LP-WUS and the corresponding PEI. In some embodiments, this time offset is between the start or end time of a set of LP-WUS or a single LP-WUS and the start time of the first PEI in the corresponding PEI. In some embodiments, this time offset is between the start or end time of a set of LP-WUS or a single LP-WUS and the reference point or start time of the first PEI in the corresponding PEI.

[0143] In some embodiments, the gNB can configure or broadcast the period and mapping of LP-WUS. In some embodiments, the period of LP-WUS can be a value, a multiple of the DRX period, or a fraction of the DRX period. The mapping between LP-WUS and the corresponding PEI is based on the DRX period. In some embodiments, the number of mappings between LP-WUS and DRX periods can be configured, such as LP-WUS corresponding to N DRX periods, where N is a positive value. In some embodiments, one or more DRX periods have X LP-WUS and Y PEIs, where X and Y are positive integers. One LP-WUS can correspond to ceil (Y / X) or floor (Y / X) PEIs.

[0144] In some embodiments, the mapping relationship between LP-WUS and the corresponding PEI is based on the LP-WUS cycle. In some embodiments, the number of mappings between LP-WUS and PEI can be configured, such as one LP-WUS corresponding to N PEIs. In one LP-WUS cycle, there are Z PEIs, where Z is a positive integer. One LP-WUS can correspond to Z PEIs.

[0145] In some embodiments, the mapping between LP-WUS and corresponding PEIs is based on paging frames or radio frames. In some embodiments, the number of mappings between LP-WUS and paging frames or radio frames can be configured; for example, one LP-WUS can correspond to all PEIs in N paging frames or radio frames, where N is a positive integer. In N paging frames or radio frames, there are X LP-WUS and Z PEIs. One LP-WUS can correspond to ceil (Z / X) or floor (Z / X) PEIs.

[0146] Figure 3 A schematic diagram illustrating the relationship between LP-WUS and PEI according to an embodiment of this disclosure is shown. Figure 3 As shown, one LP-WUS can correspond to multiple PEIs.

[0147] In some embodiments, the gNB can configure or broadcast the period of the LP-WUS, the frequency or time resources of the LP-WUS, and the mapping between the LP-WUS and the corresponding PEI. The number of LP-WUS groups in an LP-WUS period is determined by the frequency or time resources of the LP-WUS. The period of the LP-WUS can be a value, a multiple of the DRX period, or a fraction of the DRX period. For example, if there are X (X is a positive integer) LP-WUS located at different frequencies or times in a period, these X LP-WUS constitute a group of LP-WUS.

[0148] In some embodiments, the mapping relationship between the set of LP-WUS and the corresponding PEI is based on the DRX cycle. In some embodiments, the number of mappings between a set of LP-WUS and DRX cycles can be configured, such that a set of LP-WUS can correspond to N DRX cycles (N is a positive integer). In one or more DRX cycles, there are X sets of LP-WUS and Y PEIs (X and Y are positive integers). A set of LP-WUS can correspond to ceil (Y / X) or floor (Y / X) PEIs.

[0149] In some embodiments, the mapping between a group of LP-WUS and its corresponding PEI is based on the LP-WUS cycle. In some embodiments, the number of mappings between a group of LP-WUS and PEI can be configured; for example, a group of LP-WUS can correspond to N PEIs. In one LP-WUS cycle, there are Z PEIs (Z is a positive integer). A group of LP-WUS can correspond to Z PEIs.

[0150] In some embodiments, the mapping between groups of LP-WUS and their corresponding PEIs is based on paging frames or radio frames. In some embodiments, the number of mappings between a group of LP-WUS and paging frames or radio frames can be configured; for example, a group of LP-WUS may correspond to all PEIs in N paging frames or radio frames (N is a positive integer). In N paging frames or radio frames, there are X groups of LP-WUS and Z PEIs (Z is a positive integer). A group of LP-WUS may correspond to ceil (Z / X) or floor (Z / X) PEIs.

[0151] Figure 4 A schematic diagram illustrating the relationship between LP-WUS and PEI according to an embodiment of this disclosure is shown. Figure 4 As shown, one set of LP-WUS can correspond to multiple PEIs.

[0152] In some embodiments, the gNB can configure or broadcast the period of the LP-WUS, the frequency or time resources of the LP-WUS, and the total number of sub-packets of the LP-WUS. A set of LP-WUS may include multiple LP-WUS. Within a set of LP-WUS, the set of LP-WUS can be further divided into multiple parts of the LP-WUS. In one part of the LP-WUS, it can indicate the sub-packet ID of the LP-WUS.

[0153] It requires R sub-packet IDs of LP-WUS to indicate all sub-packets. Furthermore, a portion of LP-WUS can carry R sub-packet IDs, and an LP-WUS can carry Q sub-packet IDs; therefore, a portion of LP-WUS consists of ceil(R / Q) or floor(R / Q) LP-WUS units. Additionally, a set of LP-WUS units consists of X portions of LP-WUS.

[0154] Finally, the mapping relationship between this set of LP-WUS and PEI can be based on DRX cycles, LP-WUS cycles, paging frames, or radio frames. For example, a set of LP-WUS corresponds to Y PEIs (Y is a positive integer), or X parts of an LP-WUS correspond to Y PEIs, or... or Each LP-WUS corresponds to Y PEIs.

[0155] Figure 5 A schematic diagram illustrating the relationship between LP-WUS and PEI according to an embodiment of this disclosure is shown. Figure 5 As shown, a portion of a set of LP-WUS can correspond to multiple PEIs.

[0156] In some embodiments, the gNB can configure or broadcast a time offset between the LP-WUS and the corresponding PO. In some embodiments, the time offset is between the start or end time of a set of LP-WUS or a single LP-WUS and the start time of the first PO in the corresponding PO, or the time offset is between a reference point of the start or end time of a set of LP-WUS or a single LP-WUS and the start time of the first PO in the corresponding PO.

[0157] In some embodiments, the gNB can configure or broadcast the period and mapping of LP-WUS. In some embodiments, the period of LP-WUS can be a value, a multiple of the DRX period, or a fraction of the DRX period. In some embodiments, the mapping between LP-WUS and corresponding POs is based on the DRX period. In some embodiments, the number of mappings between LP-WUS and DRX periods can be configured, such as one LP-WUS corresponding to N DRX periods (N is a positive integer). In one or more DRX periods, there are X LP-WUS and Y POs (X and Y are positive integers). One LP-WUS can correspond to ceil (Y / X) or floor (Y / X) POs.

[0158] In some embodiments, the mapping relationship between LP-WUS and corresponding POs is based on the LP-WUS cycle. In some embodiments, the number of mappings between LP-WUS and POs can be configured, such as one LP-WUS corresponding to N POs (N is a positive integer). In one LP-WUS cycle, there are Z POs (Z is a positive integer). One LP-WUS can correspond to Z POs.

[0159] In some embodiments, the mapping between LP-WUS and corresponding POs is based on paging frames or radio frames. In some embodiments, the number of mappings between LP-WUS and paging frames or radio frames can be configured; for example, one LP-WUS can correspond to all POs in N paging frames or radio frames (N is a positive integer). In N paging frames or radio frames, there are Z POs (Z is a positive integer). One LP-WUS can correspond to Z POs.

[0160] Figure 6 A schematic diagram illustrating the relationship between LP-WUS and PO according to an embodiment of this disclosure is shown. Figure 6 As shown, one LP-WUS can correspond to multiple POs.

[0161] In some embodiments, the gNB can configure or broadcast the period of the LP-WUS, the frequency or time resources of the LP-WUS, and the mapping relationship between the LP-WUS and the corresponding PO. In some embodiments, the number of groups of LP-WUS in the LP-WUS period is determined by the frequency or time resources of the LP-WUS. In some embodiments, the period of the LP-WUS can be a value, a multiple of the DRX period, or a fraction of the DRX period. In some embodiments, there are X LP-WUS (where X is a positive integer) located at different frequencies or times in the period, and these X LP-WUS can be regarded as a group of LP-WUS.

[0162] In some embodiments, the mapping relationship between a group of LP-WUS and its corresponding PO is based on DRX cycles. In some embodiments, the number of mappings between a group of LP-WUS and DRX can be configured, such that a group of LP-WUS can correspond to N DRX (N is a positive integer). In one or more DRX cycles, there are X groups of LP-WUS and Y PO (X and Y are positive integers). A group of LP-WUS can correspond to ceil (Y / X) or floor (Y / X) POs.

[0163] In some embodiments, the mapping relationship between a group of LP-WUS and its corresponding PO is based on the LP-WUS cycle. In some embodiments, the number of mappings between a group of LP-WUS and PO can be configured, such that a group of LP-WUS can correspond to N POs (N is a positive integer). In one LP-WUS cycle, there are Z POs (Z is a positive integer). A group of LP-WUS can correspond to Z POs.

[0164] In some embodiments, the mapping between the set of LP-WUS and the corresponding PO is based on paging frames or radio frames. In some embodiments, the number of mappings between a set of LP-WUS and paging frames or radio frames can be configured, such that a set of LP-WUS can correspond to all POs in N paging frames or radio frames (N is a positive integer). In N paging frames or radio frames, there are Z POs (Z is a positive integer). A set of LP-WUS can correspond to Z POs.

[0165] Figure 7 A schematic diagram illustrating the relationship between LP-WUS and PO according to an embodiment of this disclosure is shown. Figure 7 As shown, one set of LP-WUS can correspond to multiple POs.

[0166] In some embodiments, the gNB can configure or broadcast the period of the LP-WUS, the frequency or time resources of the LP-WUS, and the total number of sub-packets of the LP-WUS. In some embodiments, a set of LP-WUS may include multiple LP-WUS. Within a set of LP-WUS, the set of LP-WUS is further divided into multiple parts of the LP-WUS. Within one part of the LP-WUS, it may indicate the sub-packet ID of the LP-WUS.

[0167] In some embodiments, it requires the R sub-packet ID of the LP-WUS to indicate all sub-packets. Furthermore, a portion of the LP-WUS can carry the R sub-packet ID of the LP-WUS, and the LP-WUS can carry the Q sub-packet ID of the LP-WUS; therefore, a portion of the LP-WUS consists of ceil(R / Q) or floor(R / Q) LP-WUS units. Additionally, a set of LP-WUS units consists of X portions of the LP-WUS.

[0168] Finally, the mapping between LP-WUS groups and PEIs can be based on DRX cycles, LP-WUS cycles, paging frames, or radio frames. For example, a group of LP-WUS groups corresponds to Y POs (Y is a positive integer), or X parts of an LP-WUS group correspond to Y POs, or... or One LP-WUS corresponds to Y POs.

[0169] Figure 8 A schematic diagram illustrating the relationship between LP-WUS and PO according to an embodiment of this disclosure is shown. Figure 8 As shown, a portion of a set of LP-WUS can correspond to multiple POs.

[0170] Aspect 3

[0171] In some embodiments, sub-groups of the UE can monitor the same LP-WUS. If a group including the UE is paged, the corresponding LP-WUS is sent. After receiving the LP-WUS, the UE can wake up and monitor the corresponding PEI. After receiving the LP-WUS, if the sub-group ID of the LP-WUS matches the UE's sub-group ID for the LP-WUS (e.g., configuration associated with the sub-group ID of the LP-WUS), the UE can wake up and monitor the corresponding PEI. After receiving the PEI, if the sub-group ID of the PEI indicating the monitoring of the PO matches the UE's sub-group ID for the PEI (e.g., configuration associated with the sub-group ID of the PEI), the UE can monitor the PO.

[0172] In some embodiments, LP-WUS sub-packets are partitioned based on the number of sub-packets controlled by the CN (core network) and the number of mapped sub-packets. The CN is responsible for assigning PEI sub-packet IDs (e.g., configurations associated with the PEI sub-packet IDs) to the UE. The assigned PEI sub-packet IDs are sent by the CN to the gNB via NG messages (such as paging messages). One LP-WUS sub-packet may correspond to one or more PEI sub-packets. For example, if the UE's assigned PEI sub-packet ID is x, one LP-WUS sub-packet corresponds to N PEI sub-packets, and the number of mapped sub-packets is N (N>=1). The UE's corresponding LP-WUS sub-packet ID is (x mod N) (see [link to LP-WUS documentation]). Figure 9 ).

[0173] The gNB can configure or broadcast the number of mapped sub-packets for LP-WUS. The sub-packet IDs for LP-WUS can be carried within LP-WUS or determined by LP-WUS resources. If the LP-WUS sub-packet ID matches the UE's LP-WUS sub-packet ID, the UE can wake up and monitor the corresponding PEI. For example, if the UE's assigned sub-packet ID for PEI is x, one LP-WUS sub-packet corresponds to N sub-packets of PEI, the number of mapped sub-packets is N (N>=1), and the interval is M (M>=1) (see [link to gNB]). Figure 10 ).

[0174] The gNB can configure or broadcast the number of mapped sub-packets and the LP-WUS interval. The LP-WUS sub-packet ID can be carried in the LP-WUS or determined by LP-WUS resources. If the LP-WUS sub-packet ID matches the UE's LP-WUS sub-packet ID, the UE can wake up and monitor the corresponding PEI.

[0175] In some embodiments, LP-WUS sub-packets are divided based on the sub-packets controlled by the CN and the total number of sub-packets. The CN is responsible for assigning PEI sub-packet IDs to the UE. The total number of sub-packets is M (M is a positive integer), which is broadcast by the gNB. One LP-WUS sub-packet can correspond to one or more PEI sub-packets. The total number of LP-WUS sub-packets is N (M>=N). The mapping number is Y=floor(M / N) or ceil(M / N). One LP-WUS sub-packet corresponds to Y PEI sub-packets. The gNB can configure or broadcast the total number of LP-WUS sub-packets.

[0176] In some embodiments, LP-WUS sub-packets are divided based on the number of sub-packets based on the UE ID and the number of mapped sub-packets. For PEI, UEs can be divided into different groups based on the UE ID (e.g., IMSI (International Mobile Subscriber Identity)). One sub-packet of LP-WUS may correspond to one or more sub-packets of PEI. The UE's allocated sub-packet ID for PEI is x, one sub-packet of LP-WUS corresponds to N sub-packets of PEI, and the number of mapped sub-packets is N. The UE's corresponding sub-packet ID for LP-WUS is (x mod N). In some alternative embodiments, the UE's allocated sub-packet ID for PEI is x, one sub-packet of LP-WUS corresponds to N sub-packets of PEI, and the number of mapped sub-packets is N (N>=1), and the interval is M (M>=1).

[0177] In some embodiments, LP-WUS sub-packets are divided based on UE ID-based sub-packets and the total number of sub-packets. For PEI, UEs can be divided into different groups based on UE ID (e.g., IMSI), and the total number of sub-packets is M, broadcast by the gNB. One LP-WUS sub-packet can correspond to one or more sub-packets of PEI. The total number of LP-WUS sub-packets is N. The mapping number is Y = floor(M / N) or ceil(M / N). One LP-WUS sub-packet corresponds to Y sub-packets of PEI. The gNB can configure or broadcast the total number of LP-WUS sub-packets.

[0178] In some embodiments, LP-WUS sub-packets are segmented based on CN-controlled sub-packets, and PEI sub-packets are segmented based on UEID-based sub-packets. The UE's LP-WUS sub-packet ID is determined based on the sub-packet ID assigned by the CN. The UE's PEI sub-packet ID is determined using the UE ID.

[0179] In some embodiments, LP-WUS sub-packets are segmented based on UE ID sub-packets, and PEI sub-packets are segmented based on CN-controlled sub-packets. The UE's sub-packet ID for LP-WUS is determined by the UE ID. The UE's sub-packet ID for PEI is determined by the CN-assigned sub-packet ID.

[0180] In some embodiments, if UE ID-based subpacketization of LP-WUS is supported, the gNB may configure or broadcast the configuration, which includes at least one of an indication that UE ID-based subpacketization of LP-WUS is supported, the total number of subpackets, etc.

[0181] In some embodiments, if CN-controlled subpacketization of LP-WUS is supported, the gNB can configure or broadcast the configuration, which includes at least an indication that CN-controlled subpacketization of LP-WUS is supported, the total number of subpackets, etc. The AMF can deliver the subpacket ID assigned to LP-WUS via NG messages (such as paging messages).

[0182] Aspect 4

[0183] In some embodiments, the UE and CN can negotiate whether to activate the LP-WUS function.

[0184] In some embodiments, the UE may send a NAS (Non-Access Stratum) message to the CN to request activation of the LP-WUS function. In some embodiments, the UE may send a NAS message to the CN, such as a registration request, service request, or another message. This message may carry the UE's LP-WUS capability, as well as an indication that the UE expects to activate the LP-WUS function or power-saving function.

[0185] In some embodiments, the CN may send a NAS message to the UE to activate the LP-WUS function. In some embodiments, the AMF (Access and Mobility Management Function) may send a NAS message to the UE, such as an registration acceptance, service response, or another message. This message may carry the LP-WUS configuration, and the configuration includes at least one of the following: an indication that the UE's LP-WUS function or power-saving function can be activated, an indication that LP-WUS can be sub-packetized by the CN or by UE ID-based sub-packetization, the total number of sub-packets, etc.

[0186] In some embodiments, the CN may send an NG message to the gNB to activate the LP-WUS function of the UE. In some embodiments, the AMF may send an NG message to the gNB, such as a paging message, an initial context establishment request, or another message. This message may carry a configuration for LP-WUS, and the configuration may include at least one of the following: an indication that the LP-WUS function or power-saving function of the UE can be activated; an indication that LP-WUS can be sub-grouped using CN-controlled sub-groups or UE ID-based sub-groups; a sub-group ID assigned by the CN; the total number of sub-groups; etc. The gNB may activate the LP-WUS function for the UE or send LP-WUS based on the indication from the CN.

[0187] In some embodiments, the gNB may send an NG message to the CN to activate the LP-WUS function of the UE. In some embodiments, the gNB may send an NG message to the CN, such as a UE context release request, a UE context release completion message, or another message. This message may carry a configuration for LP-WUS in idle / inactive mode, and the configuration includes at least one of the following: an indication that the UE's LP-WUS function or power-saving function can be activated, a sub-packet ID assigned by the gNB, an indication that CN-controlled sub-packets or UE ID-based sub-packets are supported for LP-WUS sub-packetization, a CN-assigned sub-packet ID, the total number of sub-packets, an indication that relaxed RRM (Radio Resource Management) measurements based on LP-WUS are configured, etc. The CN may deliver the indication for the UE to another gNB.

[0188] In some embodiments, a gNB can send an Xn message to another gNB to activate the LP-WUS function for the UE. In some embodiments, the gNB can send an Xn message such as retrieving a UE context response, RAN paging, or another message. This message may carry a configuration for LP-WUS in inactive mode, and this configuration includes at least one of the following: an indication that the UE's LP-WUS function or power-saving function can be activated; a sub-packet ID assigned by the gNB; an indication that CN-controlled sub-packets or UEID-based sub-packets are supported for LP-WUS sub-packetization; a CN-assigned sub-packet ID; the total number of sub-packets; an indication that relaxed RRM measurements based on LP-WUS are configured; and so on. The CN can deliver the indication for the UE to another gNB. The other gNB can activate or send LP-WUS for the UE based on the indication from the gNB.

[0189] Aspect 5

[0190] In some embodiments, if the gNB knows whether the conditions are met for the UE to monitor LP-WUS or LP-SS (Low Power Synchronization Signal), the gNB can determine whether to send LP-WUS or LP-SS to the UE.

[0191] In some embodiments, in an inactive state, the UE may report information about LP-WUS or LP-SS to the gNB via SDT (Small Data Transmission). In some embodiments, in an inactive state, the UE may trigger an SDT procedure if the conditions for the UE to monitor LP-WUS or LP-SS are met, or if the conditions are not met. In some embodiments, if the conditions for the UE to monitor LP-WUS or LP-SS are met, or if the conditions are not met, and if the conditions for initiating SDT are met, the UE may trigger an RRC (Radio Resource Control) connection recovery procedure via SDT. The message used to trigger the RRC connection recovery procedure (e.g., RRCResumeRequest) may carry information about LP-WUS or LP-SS in the recovery reason. In some embodiments, the information may be an indication of whether the conditions for the UE to monitor LP-WUS or LP-SS are met, or whether the state of the conditions for the UE to monitor LP-WUS or LP-SS has changed. In some embodiments, in RRCResumeRequest, the recovery reason is an indication of whether the conditions for the UE to monitor LP-WUS or LP-SS are met, or whether the state of the conditions for the UE to monitor LP-WUS or LP-SS has changed. When the gNB receives this message, it can determine whether the UE meets the conditions and whether to send LP-WUS or LP-SS to the UE.

[0192] In some embodiments, in the inactive state, the UE can report information about LP-WUS or LP-SS to the gNB via a MAC CE. In some embodiments, in the inactive state, the UE can generate a MAC CE (MAC CE) if the conditions for the UE to monitor LP-WUS or LP-SS are met, or if the conditions are not met. The MAC CE may carry an indication of whether the conditions for the UE to monitor LP-WUS or LP-SS are met, or whether the state of the conditions for the UE to monitor LP-WUS or LP-SS has changed. In the inactive state, the MAC CE can trigger an SDT procedure. In some embodiments, if a MAC CE is generated and the conditions for initiating an SDT are met, the MAC entity can instruct the RRC entity to trigger an SDT procedure. The RRC entity can then trigger an RRC connection recovery procedure via the SDT. When the MAC entity sends an RRCResumeRequest message, the MAC entity can multiplex the MAC CE with a CCCH (Common Control Channel) carrying the RRCResumeRequest. When the gNB receives the MAC CE, it can determine whether the UE meets the conditions and whether to send LP-WUS or LP-SS to the UE.

[0193] In some embodiments, in an inactive state, the UE can report information about LP-WUS or LP-SS to the gNB via a MAC CE. In some embodiments, in an inactive state, the UE can generate a MAC CE if the conditions for the UE to monitor LP-WUS or LP-SS are met, or if the conditions are not met. The MAC CE may carry an indication of whether the conditions for the UE to monitor LP-WUS or LP-SS are met. In an inactive state, the MAC CE can trigger an SDT procedure. In some embodiments, if a MAC CE is generated and the conditions for initiating an SDT are met, the UE can send the MAC CE via SDT resources. When the gNB receives the MAC CE, it can determine whether the UE meets the conditions and whether to send LP-WUS or LP-SS to the UE.

[0194] In some embodiments, in an inactive state, the UE can indicate information about LP-WUS or LP-SS to the gNB via a specific RACH resource. In some embodiments, the gNB can configure a specific RACH resource for the UE in an inactive state. The UE can send a preamble using that specific RACH resource if the conditions for the UE to monitor LP-WUS or LP-SS are met, or if the conditions are not met, or if the conditions for initiating an SDT are met. For example, if the conditions for the UE to monitor LP-WUS or LP-SS are met, or if the conditions are not met, and if the conditions for initiating an SDT are met, the UE can trigger an RRC connection recovery procedure via an SDT. The UE can choose to send a preamble on a specific RACH resource. A specific RACH resource may include a specific time, frequency, and code resource for the preamble. When the gNB receives the preamble, it can determine whether the UE meets the conditions and whether to send LP-WUS or LP-SS to the UE.

[0195] Aspect 6

[0196] In some embodiments, if the UE changes from camping in the source cell to camping in the target cell, the target cell may activate or deactivate the LP-WUS function during the handover process.

[0197] In some embodiments, the source cell transmits LP-WUS UE capabilities to the target cell. If the UE supports LP-WUS functionality, the source cell can transmit LP-WUS UE capabilities to the target cell. LP-WUS UE capabilities may include at least one of the following: whether the UE can support simplified PDCCH monitoring based on LP-WUS; whether the UE can support simplified PDCCH monitoring related to LP-WUS-based C-DRX (Connected Mode Discontinuous Receiver); whether the UE can support simplified PDCCH monitoring without LP-WUS-based C-DRX; whether the UE can support relaxed RRM measurements based on LP-WUS or LP-SS; whether the UE can support reporting auxiliary information regarding LP-WUS, etc.

[0198] In some embodiments, the source cell sends information about LP-WUS received from the CN to the target cell. The AMF can send information about LP-WUS to the source cell, and the source cell can send this information to the target cell. The information about LP-WUS may include at least one of the following: an indication that the LP-WUS function or power-saving function of the UE can be activated, an indication that LP-WUS can be sub-packetized using CN-controlled sub-packets or UE ID-based sub-packets, the total number of sub-packets, etc.

[0199] In some embodiments, the source cell sends auxiliary information about power saving or LP-WUS for the UE to the target cell. If the source cell requires auxiliary information from the UE, it may send such information to the target cell. This auxiliary information may include at least one of the following: whether the UE expects to enter sleep mode in connected or idle / inactive mode; whether the UE is power-sensitive; whether the UE expects to activate LP-WUS functionality in connected or idle / inactive mode; whether the UE expects to support simplified PDCCH monitoring related to LP-WUS-based C-DRX; whether the UE expects to support simplified PDCCH monitoring without LP-WUS-based C-DRX; whether the UE expects to support relaxed RRM measurements based on LP-WUS or LP-SS; an indication of whether LP-WUS or LP-SS conditions are met (e.g., conditions under which the UE can monitor LP-WUS or LP-SS); and so on.

[0200] In some embodiments, the source cell sends LP-WUS configuration to the target cell. If the source cell has already activated the LP-WUS function and configured the configuration, the source cell may send the LP-WUS configuration to the target cell. This configuration may include at least one of the following: an indication of whether the LP-WUS function has been activated; an indication of whether relaxed measurements based on LP-SS or LP-WUS have been configured; an indication of whether conditions for LP-WUS or LP-SS are met; a configuration regarding simplified PDCCH monitoring related to LP-WUS-based C-DRX; a configuration regarding simplified PDCCH monitoring without LP-WUS-based C-DRX; a configuration regarding relaxed RRM measurements based on LP-WUS or LP-SS; and so on.

[0201] In some embodiments, the source cell sends the LP-SS measurement results of the target cell to the target cell. The source cell can configure the LP-SS of the target cell to allow the UE to measure the LP-SS and report the measurement results. If the source cell obtains the measurement results, it can send them to the target cell. The measurement results may include the LP-SS's RSRP (Reference Received Power), RSRQ (Reference Received Quality), and RSSI (Received Signal Strength Indicator).

[0202] In some embodiments, the source cell sends the UE mobility status to the target cell. If the source cell has determined the UE mobility status, it can send it to the target cell. The UE mobility status can be static, low mobility, or high mobility.

[0203] If the source cell has activated the LP-WUS function and configured the LP-WUS settings, the source cell can send the LP-WUS settings to the target cell. The settings may include at least one of the following: an indication of whether the LP-WUS function has been activated; an indication of whether relaxed measurements based on LP-SS or LP-WUS have been configured; an indication of whether LP-WUS or LP-SS conditions are met; a configuration for simplified PDCCH monitoring related to LP-WUS-based C-DRX; a configuration for simplified PDCCH monitoring without LP-WUS-based C-DRX; a configuration for relaxed RRM measurements based on LP-WUS or LP-SS; and so on.

[0204] In some embodiments, the source cell may send the aforementioned information to the target cell via Xn messages such as handover requests and handover preparation information.

[0205] Aspect 7

[0206] In some embodiments, the UE can be woken up by LP-WUS. The UE can monitor the corresponding PEI. However, the UE may not be able to find the corresponding sub-packet ID of the PEI in the received PEI. For example, if the UE is woken up by LP-WUS corresponding to the UE's sub-packet ID for LP-WUS, the UE may not be able to detect the corresponding sub-packet of the PEI (e.g., having the UE's sub-packet ID for the PEI). In this way, the UE can still monitor the associated PO. For example, the UE wakes up when the UE's sub-packet ID for LP-WUS is X, and the received LP-WUS matches the UE's sub-packet ID for LP-WUS. When the UE's sub-packet ID for the PEI is Y, and the received PEI does not include an indication corresponding to sub-packet ID Y, the UE can continue to monitor the corresponding PO to avoid losing the paging message.

[0207] In some embodiments, the UE can be woken up by LP-WUS. The UE can choose to be served by another cell. The UE can monitor the PEI or PO in the other cell. For example, the UE camps on cell 1, receives LP-WUS from cell 1, and wakes up. Then, the UE chooses to be served by cell 2 and monitors the PEI or PO in cell 2, regardless of whether the UE receives LP-WUS in cell 2. The UE can enter a sleep mode and monitor LP-WUS in cell 2 until the conditions of LP-WUS in cell 2 are met.

[0208] In some embodiments, if the UE does not detect any LP-WUS during N DRX cycles or N time periods, the UE can wake up and measure the SSB and monitor the corresponding PO. If the UE does not detect any LP-WUS during N DRX cycles or N time periods (N is a positive number), or if there is no LP-WUS matching the UE's sub-group ID or UE ID for the LP-WUS, this may mean that the UE has moved out of the coverage area of ​​the corresponding gNB. In this case, the UE can wake up, measure the SSB, and perform cell selection or monitor the corresponding PO. The UE may consider the LP-WUS condition not met and stop monitoring LP-WUS. If the LP-WUS condition is met again later, the UE can resume monitoring LP-WUS.

[0209] Aspect 8

[0210] In some embodiments, the conditions for LP-WUS (e.g., the conditions for monitoring LP-WUS) may include:

[0211] 1) The UE does not have time-sensitive services. Because the UE needs time to wake up after detecting LP-WUS in inactive mode, the latency to access the network can be long. If the UE has time-sensitive services, LP-WUS may cause latency. Therefore, if the UE does not have time-sensitive services, the UE can meet the LP-WUS condition. In some embodiments, the UE has already established some QoS flows in inactive mode. If the time requirement of the UE's QoS flows is not critical, or the packet delay budget of the UE's QoS flows is higher than a threshold, or the latency-critical parameter of the UE's QoS flows is not latency-critical, then the UE meets the LP-WUS condition. If the QCI (QoS Class Identifier) ​​of the UE's QoS flows is not a specific value such as 5, then the UE can meet the LP-WUS condition.

[0212] 2) The gNB can configure LP-WUS conditions via RRC messages or broadcast them via SIB. The gNB can enable conditions for time-sensitive services. For example, the gNB can instruct the UE to determine conditions for time-sensitive services. The gNB can configure or broadcast thresholds for LP-WUS conditions. For example, the gNB can indicate thresholds for packet delay budgets for QoS flows.

[0213] Aspect 9

[0214] In some embodiments, the UE reports the measurement results of LP-SS.

[0215] In idle / inactive mode, the UE can measure LP-SS. If the UE meets the conditions of LP-WUS / LP-SS, the UE can measure LP-SS and obtain the measurement results. When the UE enters RRC connected mode, in order to help the gNB understand whether the UE meets the conditions of LP-WUS / LP-SS, the UE can report the measurement results of LP-SS (such as RSRP, RSSI, RSRQ).

[0216] In idle / inactive mode, the UE can obtain LP-SS measurement results. If the UE enters RRC connected mode and still meets the conditions of LP-WUS / LP-SS, the UE can report the LP-SS measurement results.

[0217] In idle / inactive mode, the UE can obtain the LP-SS measurement results. If the UE enters RRC connected mode and the LP-SS measurement results are still valid, the UE can report the LP-SS measurement results.

[0218] The UE can report LP-SS measurement results via RRC messages. If the gNB can request LP-SS measurement results in idle / inactive mode via RRC messages (such as UEInformationRequest), the UE can report LP-SS measurement results via RRC messages (such as UEInformationResponse). Alternatively, the UE can report LP-SS measurement results via RRC messages (such as RRCResumeComplete or RRCSetupComplete).

[0219] The UE can report whether it meets the LP-WUS / LP-SS conditions via RRC messages. The gNB can request the UE to report whether it meets the LP-WUS / LP-SS conditions via RRC messages (such as UEInformationRequest). If the UE meets the LP-WUS / LP-SS conditions just before entering RRC connection mode or when the UE receives the request message, the UE can report whether it meets the LP-WUS / LP-SS conditions, such as via UEInformationResponse. If the UE does not meet the LP-WUS / LP-SS conditions before entering RRC connection mode or when the UE receives the request message, or if the LP-SS measurement result is invalid, the UE can report whether it does not meet the LP-WUS / LP-SS conditions. Alternatively, if the UE satisfies the LP-WUS / LP-SS conditions just before the UE enters RRC connection mode or before the UE sends an RRC message, the UE may report an indication that the UE satisfies the LP-WUS / LP-SS conditions, such as via RRCResumeComplete or RRCSetupComplete.

[0220] Aspect 10

[0221] If the UE is configured with eDRX (Extended Discontinuous Receive), the UE can monitor LP-WUS before the PTW (Paging Time Window). If the UE receives LP-WUS and the LP-WUS indicates that the UE should wake up, the UE will wake up at the start of the PTW.

[0222] In some embodiments, the gNB may broadcast configurations regarding LP-WUS, such as the offset between the start of the PTW and the corresponding start or stop of the LP-WUS, or the offset between the start of the first DRX cycle in the PTW and the corresponding start or stop of the LP-WUS.

[0223] In some embodiments, the UE can monitor LP-WUS according to the configuration described above. If the UE receives LP-WUS and LP-WUS instructs the UE to wake up, the UE can wake up during the DRX cycle in the PTW. Otherwise, the UE can remain in idle / inactive mode and will not wake up during the DRX cycle in the PTW.

[0224] Aspect 11

[0225] In some embodiments, the gNB can configure an effective area for LP-WUS via an RRC message or broadcast the effective area via the SIB. The UE can monitor LP-WUS within this effective area. If the UE moves out of the effective area, the UE can release the LP-WUS configuration and stop monitoring the corresponding LP-WUS. The effective area can be a cell list, a frequency list, etc. In some embodiments, the gNB can configure or broadcast the LP-WUS configuration. The configuration can include the time and / or frequency resources of LP-WUS and the effective area. The effective area can be a cell ID list or a carrier frequency list.

[0226] Aspect 12

[0227] In some embodiments, the gNB can activate the LP-WUS function via the SIB. The gNB can activate the LP-WUS function and broadcast the LP-WUS configuration. The gNB can deactivate the LP-WUS function via the SIB. The gNB can deactivate the LP-WUS function and release the LP-WUS configuration.

[0228] In some embodiments, if the gNB activates the LP-WUS function and then deactivates it, the gNB may trigger a paging message to notify the UE of the SIB change. The paging message may carry an indication that the LP-WUS function has been deactivated.

[0229] In some embodiments, if the gNB activates the LP-WUS function and then deactivates it, the gNB can trigger LP-WUS to notify the UE of the SIB change. LP-WUS can carry an indication that the LP-WUS function has been deactivated.
