Signal processing method

Abstract

A signal processing method, which is executed in a user equipment. The user equipment receives configuration information, the configuration information comprising a parameter for monitoring a low-power wake-up signal (LP-WUS) and a parameter for monitoring a low-power wake-up signal (WUS) based on a physical downlink control channel (PDCCH). The user equipment monitors one of the LP-WUS or the PDCCH-based WUS. When the PDCCH-based WUS is not monitored, the user equipment determines whether to monitor a PDCCH within a first time period on the basis of the LP-WUS.

Description

Signal processing methods Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a signal processing method, user equipment, and base station. Background Art

[0002] Terminal power consumption is a key factor impacting the user experience and application of 5G and even 6G communication systems. Devices like smartphones require frequent charging, which is inconvenient for users. For sensors, wearables, and other devices, reducing power consumption is a crucial way to extend battery life and improve device reliability. For example, sensor batteries are expected to last for at least several years.

[0003] When a user device is awake, its internal modules remain powered on, allowing it to receive and transmit signals. Consequently, the device consumes relatively high power in this state. Conversely, when a user device is dormant (or sleep), some modules within the device are powered off, preventing it from receiving or transmitting signals. Consequently, the device's power consumption is significantly reduced in this sleep state. In other words, if a user device remains awake for extended periods, it will consume consistently high power.

[0004] In the Radio Resource Control (RRC) connected state, a user equipment (UE) must typically continuously monitor the Physical Downlink Control Channel (PDCCH) to obtain scheduling information. For example, if the PDCCH is transmitted with a period of one slot, the UE must monitor the PDCCH in each slot. When the Downlink Control Information (DCI) detected by the UE is downlink scheduling information, the UE receives downlink data from the base station via the Physical Downlink Shared Channel (PDSCH) based on this information. If the DCI detected by the UE is uplink scheduling information, the UE sends uplink data to the base station via the Physical Uplink Shared Channel (PUSCH) based on the uplink scheduling information. Even if the base station does not send DCI to the UE, the UE still needs to monitor the PDCCH, resulting in unnecessary waste of power consumption. Therefore, reducing unnecessary PDCCH monitoring can be used to reduce UE power consumption.

[0085] In order to make the purpose, technical solutions and advantages of this application more clear, some embodiments of this application are further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain this application and are not used to limit this application.

[0086] The relevant technical terms in this article are explained as follows:

[0087] Table 1

[0088] It should be understood that, in the present application, monitoring the low-power wake-up signal LP-WUS means monitoring LP-WUS at the LP-WUS monitoring opportunity, and not monitoring the low-power wake-up signal LP-WUS means not monitoring LP-WUS at the LP-WUS monitoring opportunity. Monitoring the wake-up signal WUS based on the physical downlink control channel PDCCH means monitoring the PDCCH-based WUS at the monitoring opportunity of the PDCCH-based WUS; not monitoring the PDCCH-based WUS means not monitoring the PDCCH-based WUS at the PDCCH-based WUS monitoring opportunity. Not monitoring can be interpreted as stopping monitoring, or skipping monitoring. It should be understood that, in the present application, the measured value of the signal can be RSRP and / or SINR.

[0089] Referring to Figure 1 , one or more core network devices (e.g., core network device 30) are connected to multiple base stations 20a, including base stations 20a, 20a, 20b, ..., 20m. The multiple base stations 20a are connected to multiple user equipment (UEs) 10a, 10b, ..., 10n via wireless channels. m and n can be positive integers. The base station 20a mentioned in this application can be one of the base stations 20a in Figure 1 , such as one of base stations 20a-20m. The terminal or user equipment mentioned in this application can be one of the user equipment (UE) in Figure 1 , such as one of UEs 10a-10n.

[0090] 1. Connected-discontinuous reception (C-DRX)

[0091] C-DRX is a basic solution for saving power in user equipment (UE). Base station 20a configures C-DRX parameters for UEs. These parameters include the C-DRX cycle (called a DRX cycle). Typically, a DRX cycle includes an active time and an inactive time. During the C-DRX active time, the UE monitors the PDCCH during its listening time, but not during its inactive time, thereby saving power, as shown in Figure 2.

[0092] The C-DRX activation time includes the running time of drx-onDurationTimer, drx-InactivityTimer, drx-RetransmissionTimerDL, and drx-RetransmissionTimerUL. drx-onDurationTimer can be called the DRX duration timer; drx-InactivityTimer can be called the DRX inactivity timer; drx-RetransmissionTimerDL can be called the DRX downlink retransmission timer; and drx-RetransmissionTimerUL can be called the DRX uplink retransmission timer.

[0093] The specific plan for C-DRX is as follows:

[0094] 1) The base station 20a sends C-DRX parameters to the user equipment through RRC signaling. The C-DRX parameters and parameter descriptions are shown in Table 2.

[0095] Table 2

[0096] 2) The UE (e.g., at least one of UEs 10a-10n) runs a drx-onDurationTimer (the duration of the drx-onDurationTimer herein is referred to as OnDuration) and monitors the PDCCH during this timer. If no scheduling occurs during the drx-onDurationTimer, and the drx-InactivityTimer, drx-RetransmissionTimerDL, and drx-RetransmissionTimerUL periods are not running, the UE enters an inactive period and may not monitor the PDCCH.

[0097] If a long DRX cycle is used, the UE determines the start time of the drx-onDurationTimer according to the following formula:

[0098] [(SFN×10)+subframe number]modulo(drx-LongCycle)=drx-StartOffset

[0099] (Formula 1)

[0100] If a short DRX cycle is used, the UE determines the start time of the drx-onDurationTimer according to the following formula:

[0101] [(SFN×10)+subframe number]modulo(drx-ShortCycle)=(drx-StartOffset)

[0102] modulo(drx-ShortCycle) (Formula 2)

[0103] Where drx-LongCycle, drx-ShortCycle, and drx-StartOffset are parameters configured by base station 20a in step 1). SFN represents the system frame number, subframe number represents the subframe number, and modulo represents the modulo calculation. After the subframe start offset drx-SlotOffset satisfies the above formula, the UE begins running drx-onDurationTimer. According to this formula, drx-onDurationTimer occurs periodically.

[0104] 3) When the PDCCH schedules new data transmission, the UE starts or restarts the drx-InactivityTimer after receiving the PDCCH. During the drx-InactivityTimer, the UE continues to monitor the PDCCH.

[0105] 4) If the PDCCH schedules downlink data, or indicates one-shot HARQ feedback, or indicates retransmission of HARQ feedback, the user equipment starts or restarts the drx-HARQ-RTT-TimerDL of the corresponding HARQ process after the HARQ feedback. When the drx-HARQ-RTT-TimerDL expires and the data decoding error of the corresponding HARQ process occurs, the user equipment starts the drx-RetransmissionTimerDL of the HARQ process. While the drx-RetransmissionTimerDL is running, the UE continues to monitor the PDCCH.

[0106] 5) If the PDCCH schedules uplink data, the user equipment starts or restarts the drx-HARQ-RTT-TimerUL for the corresponding HARQ process after the PUSCH. When the drx-HARQ-RTT-TimerUL expires, the user equipment starts the drx-RetransmissionTimerUL for the HARQ process. During the drx-RetransmissionTimerUL period, the UE monitors the PDCCH.

[0107] FIG3 shows an example of activation time of the Physical Downlink Shared Channel (PDSCH).

[0108] In the C-DRX mechanism, a long DRX cycle and a short DRX cycle can be switched, as shown in Figure 4. The length of the long DRX cycle is an integer multiple of the short DRX cycle.

[0109] The method of switching from a long DRX cycle to a short DRX cycle is as follows:

[0110] a) drx-InactivityTimer expires, or,

[0111] b) A UE (e.g., at least one of UEs 10a-10n) receives a Medium Access Control (MAC) control element (CE) indicating the use of a short DRX cycle. In response to the MAC CE, the UE starts or restarts a drx-ShortCycleTimer and uses the short DRX cycle.

[0112] Methods for switching from a short DRX cycle to a long DRX cycle:

[0113] a) drx-ShortCycleTimer expires, then the UE uses a long DRX cycle; or

[0114] b) The UE receives a MAC CE, where the MAC CE indicates the use of a long DRX cycle.

[0115] The UE responds to the MAC CE and uses a long DRX cycle.

[0116] It should be noted that the downlink control information (DCI) carried by the PDCCH in the above-mentioned C-DRX mechanism mainly refers to the DCI scrambled by at least one of the following radio network temporary identities (RNTI): C-RNTI, CI-RNTI, CS-RNTI, INT-RNTI, SFI-RNTI, SP-CSI-RNTI, TPC-PUCCH-RNTI, TPC-PUSCH-RNTI, TPC-SRS-RNTI, AI-RNTI, SL-RNTI, SLCS-RNTI and SL Semi-Persistent Scheduling V-RNTI. For some cell-common DCI, such as DCI scrambled by RNTIs such as SI-RNTI and P-RNTI, it is not affected by C-DRX.

[0117] For C-DRX, the parameters in Table 2 are configured per UE. This means that the parameters can vary between UEs. In other words, the C-DRX cycle can vary for different UEs, and the starting position and length of the drx-onDurationTimer can also vary.

[0118] 2. PDCCH based wake-up signal (PDCCH based WUS):

[0119] On the basis of C-DRX, a wake-up signal based on PDCCH (abbreviated as WUS) is introduced to further reduce the power consumption of user equipment. The UE (for example, at least one of UE 10a-10n) monitors the WUS for a period of time before the start time of drx-onDurationTimer, and the WUS is carried by PDCCH. As shown in Figure 5, when the WUS indication is a first value, for example, "0", the UE does not need to start the drx-onDurationTimer of the next DRX cycle (DRX cycle), and thus does not need to monitor the PDCCH. When the WUS indication is a second value, for example, "1", the UE needs to monitor the PDCCH to start the drx-onDurationTimer of the next DRX cycle (DRX cycle).

[0120] DCI format 2_6 (DCI format 2_6) is a DCI for carrying WUS. Specifically, the base station 20a (for example, at least one of the base stations 20a-20m) will configure the search space set (SS set) of DCI format2_6 to the UE (for example, at least one of the UEs 10a-10n). The search space set is used to determine the candidate PDCCH carrying DCI format2_6. The parameters of the search space set include the period for monitoring PDCCH (PDCCH monitoring periodicity), the offset within the period (PDCCH monitoring offset), the number of time slots (duration) Ts for continuous monitoring of PDCCH within the period, etc. As shown in Figure 6, the period (periodicity) indicates the period for monitoring PDCCH, the offset value within the period is 0, and the duration duration = 3 means monitoring PDCCH on 3 consecutive time slots within one period. However, for WUS, the UE does not need to monitor DCI format 2_6 on all PDCCH monitoring opportunities (each small square in Figure 6). As shown in Figure 6, the UE monitors DCI format 2_6 at the monitoring opportunity within the second periodicity. The specific implementation method is: in addition to the search space set, the base station 20a will also configure the parameter ps-Offset to the UE, which represents the offset relative to the start time of drx-onDurationTimer. The start time of the drx-onDurationTimer is the start time of OnDuration. In addition, the UE will report the signaling of the UE capability to the base station 20a, and the signaling of the UE capability is used to indicate the latest time that the UE monitors WUS before drx-onDurationTimer, that is, MinTimeGap in Figure 6. Within the time window between ps-Offset and MinTimeGap, DCI format 2_6 is monitored at the PDCCH monitoring opportunity within the first duration.

[0121] Among them, WUS can only control whether drx-onDurationTimer is turned on when the long DRX cycle is used, that is, when the long DRX cycle is used, the UE monitors WUS before drx-onDurationTimer, and when the short DRX cycle is used, the UE does not need to monitor WUS before drx-onDurationTimer, and the UE turns on drx-onDurationTimer by default.

[0122] 3. Low Power-Wake Up Signal (LP-WUS)

[0123] In order to further save the power consumption of user equipment, 3GPP will introduce a low power-wake up receiver (LP-WUR or LR) and LP-WUS. The UE can detect LP-WUS through LR and can also receive a low power-synchronization signal (LP-SS). The power consumption of the UE in processing LP-SS and LP-WUS in LR can be very low. The main receiver (MR) of the UE is used to process existing signals in the NR system, including SSB, PDCCH, PDSCH, PUSCH, PUCCH, CSI-RS, SRS, etc. The main receiver has high requirements for time / frequency synchronization, large bandwidth, high throughput, and large power consumption. Generally, the architecture of the main receiver is shown in Figure 7. The signal of the main receiver needs to pass through a bandpass filter BPF, a low noise amplifier LNA, a low pass filter LPF, an analog-to-digital converter ADC, a fast Fourier transform FFT and a baseband processor BB. Here, RF BPF stands for RF bandpass filter, RF LNA stands for RF low-noise amplifier, LO stands for local oscillator, BB LPF stands for baseband low-pass filter, ADC stands for analog-to-digital converter, FFT stands for fast Fourier transform, and BB proc stands for baseband processing, including channel estimation, demodulation, and decoding. The high-precision RF LNA and high-precision local oscillator on the main receiver consume more power, while the high-sampling-rate ADC, high-order FFT, and baseband processing also consume more power.

[0124] Referring to Figure 8, the LP-WUR architecture differs from the main receiver. Currently, various LP-WUR receiver architectures exist, including RF envelope detection, heterodyne architecture with IF envelope detection, and homodyne / zero-IF architecture with baseband envelope detection. Figure 8 shows an LP-WUR receiver using RF envelope detection as an example. Compared to the main receiver, the absence of an LO significantly reduces power consumption. Some components, such as the RF LNA and BB LPF, can be selectively used.

[0125] 3GPP discusses power consumption models for LR and MR. Depending on the LR implementation, the relative power required to detect LP-WUS ranges from approximately 0.01 to 30. The relative power required to monitor the PDCCH on the MR is 100. Therefore, to conserve user equipment power, when no data is being transmitted, the user equipment can detect signals on the LR, while the MR can enter a sleep state, thereby saving power. When data is being transmitted, the user equipment can transmit to and from the base station 20a on the MR, ensuring throughput.

[0126] As shown in Figure 9, when the base station 20a has no data to transmit to the user equipment 10a, the MR 14 is in a disabled state and the LR 15 is in an enabled state. As shown in Figure 10, when the base station 20a has data to transmit to the user equipment 10a, it sends an LP-WUS to the LR 15, and the LR 15 wakes up the MR 14 based on the LP-WUS.

[0127] In 3GPP discussions, there are two possible monitoring modes for LP-WUS. One is continuous monitoring, where the LP-WUS is always on, which helps reduce latency. The other is duty cycle monitoring, where the LP-WUS can be periodically switched on and off, which helps save power.

[0128] In addition, LP-WUS can be activated and / or deactivated. Activating LP-WUS means that the user equipment needs to monitor LP-WUS during the LP-WUS monitoring period. When LP-WUS is deactivated, the user equipment does not need to monitor LP-WUS during the LP-WUS monitoring period. There are several ways to activate / deactivate LP-WUS monitoring:

[0129] - Mode 1: The base station 20a sends an RRC signaling instruction to the user equipment 10a to activate or deactivate the LP-WUS

[0130] - Mode 2: The base station 20a notifies the user equipment to activate or deactivate LP-WUS through L1 or L2 signaling

[0131] - Mode 3: Based on predefined rules, such as a timer, the user equipment activates or deactivates LP-WUS

[0132] Figure 11 uses continuous monitoring as an example. The UE continuously monitors the LP-WUS on the LR. Upon detecting that the LP-WUS indicates that the UE should monitor the PDCCH, the UE needs to monitor the PDCCH on the MR. The DCI may indicate deactivation of the LP-WUS. Upon receiving the deactivation instruction, the UE no longer needs to monitor the LP-WUS on the LR.

[0133] FIG12 takes a duty cycle monitoring mode as an example. The user equipment periodically monitors the LP-WUS on the LR. When it is detected that the LP-WUS instructs the user equipment to monitor the PDCCH, the user equipment needs to monitor the PDCCH on the MR. The DCI may indicate deactivation of the LP-WUS. After receiving the instruction to deactivate the LP-WUS, the user equipment no longer needs to monitor the LP-WUS on the LR.

[0134] Technical Question 1:

[0135] The existing protocol supports the PDCCH-based WUS feature. Therefore, there are several possible solutions between PDCCH-based WUS and LP-WUS:

[0136] ● Solution 1: The UE may be configured with both PDCCH-based WUS and LP-WUS, but the UE only monitors one of the WUS signals based on certain conditions. It can be considered that under certain conditions, one of the WUS functions is not enabled.

[0137] ● Solution 2: The UE may be configured with both PDCCH-based WUS and LP-WUS. The UE first monitors the LP-WUS to decide whether to wake up the primary receiver (or whether to monitor the PDCCH). When the LP-WUS indicates that the primary receiver should be woken up (or instructs the UE to monitor the PDCCH), the UE wakes up the primary receiver and starts monitoring the PDCCH-based WUS. Then, based on the indication of the PDCCH-based WUS, the UE determines whether to run the drx-onDurationTimer and whether to continue monitoring the PDCCH.

[0138] For Solution 1 and Solution 2, the collaboration between the PDCCH-based WUS and the LP-WUS needs to be further addressed.

[0139] There are two possible configuration methods for LP-WUS:

[0140] Configuration method 1: Periodic monitoring. The drx-onDurationTimer of C-DRX is used as the reference point. The monitoring timing of LP-WUS is related to C-DRX.

[0141] Configuration method 2: Periodic monitoring, but the LP-WUS duty cycle is configured independently and is not related to the C-DRX cycle. In this case, LP-WUS may be active during C-DRX activation time or inactive time.

[0142] The present invention mainly solves the technical problems of Solution 1 and Solution 2. The present invention solves the problem of collaboration between PDCCH-based WUS and LP-WUS based on different monitoring modes of LP-WUS.

[0143] Technical Question 2:

[0144] In the connected state, LP-WUS is mainly used to trigger PDCCH monitoring, and the UE will not enter ultra deep sleep in the connected state. RRM / RLM / BFD / CSI measurements still need to be performed on the MR. Based on this, in the connected state, in order to ensure the performance of the system (throughput, latency), the UE can trigger an uplink signal. The present invention also provides a solution to the impact of uplink signals on LP-WUS. Uplink signals include: SR, PRACH, CSI reporting, HARQ-ACK, BSR, CG PUSCH, SRS.

[0145] The specific technical solutions of the present invention include:

[0146] 1. In some embodiments of the present invention, the UE only monitors one of the WUS signals, LP-WUS and PDCCH-based WUS. In some embodiments of the present invention, different OnDuration processing methods are provided for different WUS signals to solve the error case behavior and the short DRX cycle behavior, thereby saving the power consumption of the user equipment.

[0147] 2. In some embodiments of the present invention, the UE first monitors the LP-WUS and then monitors the PDCCH-based WUS. In some embodiments of the present invention, the UE saves power consumption of the user equipment by adjusting the timing relationship between the LP-WUS and the PDCCH-based WUS.

[0148] 3. In some embodiments of the present invention, the UE triggers uplink signals and resumes PDCCH monitoring to ensure latency / throughput of the primary link. Uplink signals include: SR, PRACH, CG PUSCH, and BSR. When the LP-WUS indicates that the primary receiver is not awake, the UE can still report HARQ-ACK, CSI, and SRS.

[0149] 14 , a signal processing method executed in a user equipment is described below.

[0150] Step S001: The base station 20a sends configuration information to the user equipment 10a.

[0151] Accordingly, the user equipment 10a receives the configuration information, which includes parameters for monitoring a low power consumption wake-up signal LP-WUS and parameters for monitoring a low power consumption wake-up signal WUS based on a physical downlink control channel PDCCH.

[0152] Step S003: The base station 20a sends at least one of the LP-WUS and the PDCCH-based WUS to the user equipment 10a. When the PDCCH-based WUS is not monitored by the user equipment, it is determined whether the user equipment monitors the PDCCH within a first time period.

[0153] Accordingly, the user equipment 10a monitors one of the LP-WUS and the PDCCH-based WUS. When not monitoring the PDCCH-based WUS, the user equipment 10a determines whether to monitor the PDCCH within a first time period according to the LP-WUS.

[0154] In some new embodiments of the present invention, the length of the first time period is the length of a C-DRX duration timer (drx-onDurationTimer), and the starting position of the first time period is the starting moment of the duration timer.

[0155] In some new embodiments of the present invention, the length of the first time period is the length of a C-DRX duration timer, and the starting position of the first time period is determined according to the time position of the LP-WUS.

[0156] In some new embodiments of the present invention, the length of the first time period is the length of a C-DRX inactivity timer (drx-InactivityTimer), and the starting position of the first time period is determined according to the time position of the LP-WUS.

[0157] In some new embodiments of the present invention, the length of the first time period is configured by the base station, and the starting position of the first time period is determined according to the LP-WUS.

[0158] 15 , a signal processing method executed in a user equipment is described below.

[0159] Step S011: The base station 20a sends configuration information to the user equipment 10a.

[0160] Correspondingly, the user equipment 10a receives the configuration information, where the configuration information includes parameters for receiving a low power consumption wake-up signal LP-WUS.

[0161] Step S013: The base station 20a sends a first LP-WUS to the user equipment 10a.

[0162] The user equipment 10a receives a first LP-WUS. The user equipment 10a may determine multiple monitoring opportunities of the LP-WUS according to the configuration information, where the first LP-WUS is an LP-WUS received at one of the multiple monitoring opportunities.

[0163] Step S016: The user equipment 10a triggers or sends an uplink signal, where the uplink signal includes at least one of an SR, a preamble, a message A msgA, a semi-persistently scheduled PUSCH, and a BSR;

[0164] The user equipment 10a determines whether to monitor the PDCCH based on the LP-WUS and the uplink signal; or the user equipment 10a determines whether to receive a second LP-WUS based on the uplink signal. The second LP-WUS is an LP-WUS received at a different monitoring opportunity than the first monitoring opportunity.

[0165] The base station determines whether the user equipment 10a monitors the PDCCH according to the LP-WUS and the uplink signal, or determines whether the user equipment receives a second LP-WUS according to the uplink signal.

[0166] 16 , a signal processing method executed in a user equipment is described below.

[0167] Step S021: The base station 20a sends an LP-WUS to the user equipment 10a.

[0168] The user equipment 10a receives a low power wake-up signal LP-WUS, where the low power wake-up signal LP-WUS indicates not to monitor a physical downlink control channel PDCCH.

[0169] Step S024: During the period when the user equipment is not monitoring the PDCCH, the user equipment 10a determines whether to send an uplink signal, where the uplink signal includes at least one of hybrid automatic repeat request feedback information HARQ-ACK, channel state information CSI, and a sounding reference signal SRS. During the period when the user equipment is not monitoring the PDCCH, the base station determines whether to receive an uplink signal, where the uplink signal includes at least one of hybrid automatic repeat request feedback information HARQ-ACK, channel state information CSI, and a sounding reference signal SRS.

[0170] Example 1:

[0171] This embodiment addresses the issue of a UE monitoring only one type of WUS signal: LP-WUS or PDCCH-based WUS. This embodiment includes handling error cases for PDCCH-based WUS, handling LP-WUS for short DRX cycles, and handling wake-up times when the LP-WUS cycle and C-DRX cycle do not match.

[0172] 17 , the process between the base station 20a and the user equipment 10a is roughly as follows:

[0173] Step A1: The base station 20a sends C-DRX, LP-WUS, and PDCCH-based WUS related parameters to the user equipment 10a. For details, please refer to the above description.

[0174] The base station 20a sends LP-WUS-related parameters to the user equipment 10a. The parameters may include the time / frequency location of the LP-WUS monitoring opportunity and may also configure the LP-WUS period. The user equipment 10a may determine the PDCCH-based WUS monitoring opportunity based on the PDCCH-based WUS-related parameters. The user equipment 10a may determine the LP-WUS monitoring opportunity based on the LP-WUS-related parameters.

[0175] Step A2: The user equipment 10a monitors LP-WUS or PDCCH-based WUS.

[0176] Accordingly, the base station 20a may send an LP-WUS or a PDCCH-based WUS.

[0177] The user equipment 10a monitors only one type of WUS signal according to some conditions, and the function of the other WUS is disabled.

[0178] ■For example, after LP-WUS is activated, the user equipment 10a monitors LP-WUS and ignores PDCCH-based WUS (i.e., LP-WUS replaces the function of PDCCH-based WUS); when LP-WUS is deactivated, the user equipment 10a monitors PDCCH-based WUS and does not monitor LP-WUS.

[0179] ■For another example, the user equipment 10a uses LP-SS to measure LP-RSRP and LP-SINR, and determines whether to monitor LP-WUS or PDCCH-based WUS based on the LP-RSRP and LP-SINR. For example, when the LP-SS measurement value is greater than a threshold, the user equipment 10a monitors LP-WUS; otherwise, the user equipment 10a monitors PDCCH-based WUS. The LP-SS measurement value may be LP-RSRP or LP-SINR.

[0180] In the example of FIG14 , when the LP-WUS measurement value is greater than a predefined threshold, the user equipment monitors the LP-WUS at the LP-WUS monitoring opportunity during the first time period. When the LP-WUS measurement value is greater than the predefined threshold, the base station determines that the user equipment monitors the LP-WUS at the LP-WUS monitoring opportunity during the first time period.

[0181] Option 1: Using the C-DRX OnDuration as a reference point, the LP-WUS monitoring timing is related to C-DRX. Referring to Figure 18 , for example, using the C-DRX OnDuration as a reference point, the LP-WUS monitoring timing is determined based on offsets offset1 and offset2.

[0182] In the example of FIG14 , the listening period of the LP-WUS is based on the duration timer of the C-DRX as a reference point.

[0183] According to the prior art, the user equipment 10a is configured with a PDCCH-based WUS function, but the user equipment 10a does not monitor the PDCCH-based WUS, and the user equipment 10a will wake up OnDuration. In the prior art, because the PDCCH-based WUS conflicts with other behaviors, for example, it conflicts with the uplink symbol, or conflicts with the bandwidth part (Bandwidth Part, BWP) switching time, the user equipment 10a does not monitor the PDCCH-based WUS. In order to ensure throughput and latency, the user equipment will wake up the duration timer and monitor PDCCH. However, after the introduction of LP-WUS, LP-WUS can be used to indicate the PDCCH monitoring behavior. This default wake-up drx-onDurationTimer behavior is not conducive to power consumption saving of the user equipment 10a. Therefore, this embodiment proposes:

[0184] When the user equipment 10a is configured with the PDCCH-based WUS function, the user equipment 10a does not monitor the PDCCH-based WUS:

[0185] (1) If LP-WUS is not activated or configured, the user equipment 10a turns on OnDuration and monitors the PDCCH while the duration timer is running; and

[0186] (2) If LP-WUS is configured and activated, the user equipment 10a determines whether to enable OnDuration according to the LP-WUS.

[0187] In the prior art, PDCCH-based WUS is monitored only during a long DRX cycle and not during a short DRX cycle. Furthermore, the user equipment 10a turns on OnDuration and monitors the PDCCH by default. Therefore, this embodiment proposes the behavior of LP-WUS during a short DRX cycle. When a short DRX cycle is used, the specific method includes:

[0188] (1) The user equipment 10a may determine whether to enable the OnDuration of the short DRX cycle according to the LP-WUS;

[0189] (2) Furthermore, the user equipment 10a does not need to monitor the LP-WUS before the OnDuration of each short DRX cycle. One LP-WUS can control N short DRX cycles, that is, one LP-WUS can indicate whether the duration timers of N short DRX cycles are enabled and whether to monitor the PDCCH. Referring to FIG. 19 , for example, the LP-WUS can control the enabling of N short DRX cycles, where N=2.

[0190] In the example of FIG14 , when the C-DRX short cycle (drx-ShortCycle) is used, the user equipment monitors the LP-WUS at the LP-WUS monitoring opportunity. When the C-DRX short cycle (drx-ShortCycle) is used, the base station determines that the user equipment monitors the LP-WUS at the LP-WUS monitoring opportunity. The user equipment determines whether to monitor the PDCCH based on the LP-WUS. The base station determines whether the user equipment monitors the PDCCH based on the LP-WUS.

[0191] The LP-WUS indicates whether to monitor the PDCCH within N cycles of C-DRX, where N is greater than or equal to 1.

[0192]

[0193] Option 2: Referring to Figure 20, LP-WUS is monitored periodically, but the LP-WUS cycle is decoupled from the C-DRX cycle. That is, the LP-WUS cycle is independent of the C-DRX cycle. In this case, LP-WUS may be monitored during C-DRX active or inactive periods.

[0194] The user equipment 10a determines the position to monitor the PDCCH according to the LP-WUS and the PDCCH-based WUS:

[0195] (1) When the user equipment 10a monitors the WUS based on the PDCCH, the user equipment 10a determines the position of the drx-onDurationTimer according to the existing C-DRX method, determines whether to run the drx-onDurationTimer according to the WUS based on the PDCCH, and monitors the PDCCH during the running period of the drx-onDurationTimer;

[0196] (2) When the user equipment 10a monitors LP-WUS, the user equipment 10a ignores the existing C-DRX drx-onDurationTimer position, but determines the position of monitoring PDCCH according to the position of LP-WUS. For example, when LP-WUS instructs the user equipment 10a to monitor PDCCH, the user equipment 10a starts monitoring PDCCH at an interval of X after the symbol or time slot where the LP-WUS is located. The duration of monitoring PDCCH can be the duration of drx-onDurationTimer or the duration of drx-InactivityTimer. It can also be understood that the user equipment 10a starts running drx-onDurationTimer at an interval of X after the symbol or time slot where the LP-WUS is located, and the user equipment 10a monitors PDCCH during the running period of drx-onDurationTimer, or starts running drx-InactivityTimer, and the user equipment 10a monitors PDCCH during the running period of drx-InactivityTimer. This method does not require the addition of new parameters.

[0197] (3) Or, before the user equipment monitors LP-WUS, for example, in step A1, the base station additionally configures a time window (or activation time) for use when LP-WUS wakes up the user equipment 10a, that is, the user equipment 10a monitors PDCCH within the time window. The user equipment 10a opens the time window at an interval of X after the symbol or time slot where the LP-WUS is located, without opening the drx-onDurationTimer. This time window is the time when the user equipment 10a wakes up, and its length may be the same as or different from the length of the drx-onDurationTimer, and its time position is not necessarily the same as the drx-onDurationTimer of the C-DRX. In some embodiments, the start time of the drx-onDurationTimer of the discontinuous reception C-DRX in the connected state or the time window is based on the time position of the LP-WUS monitored by the user equipment as a reference point.

[0198] In the example of FIG14 , the starting position of the first time period is the time position of the interval X after the start time position or the end time position of the LP-WUS, where X is greater than or equal to 0. In the present invention, X is greater than or equal to 0, and the time unit of X can be seconds, milliseconds, frames, subframes, time slots, symbols, etc., which is not limited in the present invention.

[0199] In the example of FIG14 , during the first time period, when the LP-WUS is activated, the user equipment monitors the LP-WUS at the LP-WUS monitoring timing, and does not monitor the PDCCH-based WUS at the PDCCH-based WUS monitoring timing. During the first time period, when the LP-WUS is deactivated, the user equipment monitors the PDCCH-based WUS at the PDCCH-based WUS monitoring timing. On the network side, during the first time period, when the LP-WUS is activated, the base station determines that the user equipment monitors the LP-WUS at the LP-WUS monitoring timing, and does not monitor the PDCCH-based WUS at the PDCCH-based WUS monitoring timing. During the first time period, when the LP-WUS is deactivated, it is determined that the user equipment monitors the PDCCH-based WUS at the PDCCH-based WUS monitoring timing.

[0200] Step A4: The user equipment 10a determines whether to monitor the PDCCH next according to the LP-WUS or the PDCCH-based WUS. The time period or position for monitoring the PDCCH can refer to the above description.

[0201] Step A5: When the LP-WUS or the PDCCH-based WUS instructs the user equipment 10a to monitor the PDCCH next, the base station 20a may also send the PDCCH in the corresponding time period.

[0202] Example 2:

[0203] This embodiment solves the problem of monitoring the LP-WUS first and then the PDCCH-based WUS. This embodiment includes: the timing relationship between the LP-WUS and the PDCCH-based WUS.

[0204] In step A2 of embodiment 1, the user equipment 10a first monitors the LP-WUS to determine whether to wake up the primary receiver (or whether to monitor the PDCCH). When the LP-WUS indicates that the primary receiver should be woken up (or instructs the user equipment 10a to monitor the PDCCH), the user equipment 10a wakes up the primary receiver and starts monitoring the PDCCH-based WUS. Then, based on the indication of the PDCCH-based WUS, the user equipment 10a determines whether to run the drx-onDurationTimer and whether to continue monitoring the PDCCH:

[0205] Option 1: Periodically monitor the LP-WUS. Using the C-DRX drx-onDurationTimer as a reference point, the LP-WUS monitoring timing is related to C-DRX. Referring to Figure 18 , for example, using the C-DRX drx-onDurationTimer as a reference point, the LP-WUS monitoring timing is determined based on offsets offset1 and offset2.

[0206] In the prior art, a user equipment only needs to monitor the PDCCH-based WUS during the first duration within the WUS time window (the duration is the duration configured by the search space set (SS set) of DCI format 2_6, as shown in D01 in Figure 18, i.e., the duration within the first cycle of the PDCCH within the WUS time window). However, the user equipment 10a may miss the first duration when monitoring the LP-WUS, depending on the time position of the detected LP-WUS and the delay required to wake up the primary receiver (the delay is expressed as a duration X). In this case, the behavior of the user equipment 10a needs to be specified. Therefore, the following solutions are provided:

[0207] Solution 1: When the user equipment 10a detects LP-WUS, after a duration X, the user equipment 10a misses the first duration, then the user equipment 10a can monitor the PDCCH-based WUS in the next duration (i.e., the duration of the next cycle of PDCCH in the WUS time window). Specifically, if the time position of the interval duration X after the time position of the user equipment receiving the LP-WUS is within or after Ts time slots in the first cycle of monitoring PDCCH in the second time period, then the user equipment monitors the PDCCH-based WUS in Ts time slots in the non-first cycle of monitoring PDCCH in the second time period, the value of Ts is greater than or equal to 1, the first group of Ts time slots is the duration of monitoring PDCCH in the first PDCCH cycle in the second time period, and the PDCCH is used to carry the PDCCH-based WUS. The second time period is used to monitor the PDCCH-based WUS. The second group of Ts time slots is spaced after the time position of the LP-WUS for a duration X, and the second time period is used to monitor the PDCCH-based WUS. The second time period is the time period after the first duration. In another embodiment, the user equipment 10a can monitor the PDCCH-based WUS during the duration after the LP-WUS (i.e., the first duration after the LP-WUS and within the WUS time window). In the present invention, X is greater than or equal to 0, and the time unit of X can be seconds, milliseconds, frames, subframes, time slots, symbols, etc., which is not limited by the present invention.

[0208] In the example of Figure 14, the time position of the interval length X after the time position of the LP-WUS received by the user equipment is within or after Ts time slots in the first cycle of monitoring PDCCH in the second time period, and the base station determines that the user equipment monitors the PDCCH-based WUS in Ts time slots in the non-first cycle of monitoring PDCCH in the second time period, the value of Ts is greater than or equal to 1, the PDCCH is used to carry the PDCCH-based WUS, and the second time period is used to monitor the PDCCH-based WUS.

[0209] Solution 2: When the user equipment 10a detects the LP-WUS, after a duration X, the user equipment 10a misses the first duration, and the user equipment 10a wakes up the drx-onDurationTimer of the C-DRX by default.

[0210] In the example of FIG14 , the user equipment receives an LP-WUS, and the time position of the interval length X after the time position of the LP-WUS is within or after Ts time slots in the first cycle of monitoring the PDCCH in the second time period, then the C-DRX duration timer is started, and the user equipment monitors the PDCCH during the operation of the duration timer, the value of Ts is greater than or equal to 1, and the second time period is used to monitor the PDCCH-based WUS. The base station sends an LP-WUS, and the time position of the interval length X after the time position of the LP-WUS is within or after Ts time slots in the first cycle of monitoring the PDCCH in the second time period, then the C-DRX duration timer is started, and it is determined that the user equipment monitors the PDCCH during the operation of the duration timer, the value of Ts is greater than or equal to 1, and the second time period is used to monitor the PDCCH-based WUS.

[0211] The user equipment determines a monitoring period for the low-power wake-up signal LP-WUS based on the parameter for monitoring the LP-WUS, where the end time of the monitoring period for the LP-WUS is before the start time of a second time period. The second time period is used to monitor the PDCCH-based WUS. The base station determines a monitoring period for the LP-WUS, where the end time of the monitoring period for the LP-WUS is before the start time of the second time period, and the second time period is used for the user equipment to monitor the PDCCH-based WUS.

[0212] Solution 3: Before the user equipment 10a monitors the LP-WUS, for example, before step A2, the user equipment 10a reports the duration required to wake up the primary receiver as the minimum value of the time offset offset1 between the time location of LP-WUS detection and the time location of LP-WUS waking up the primary receiver. The base station configures the time offset offset1 based on this minimum value and ps-offset to ensure that the user equipment 10a monitors the LP-WUS before starting to monitor the PDCCH-based WUS. ps-offset is the offset of the starting point of the PDCCH-based WUS time window relative to the starting point of drx-onDurationTimer.

[0213] In the example of FIG14 , before receiving the LP-WUS, the user equipment sends a minimum duration, where the minimum duration refers to the duration during which the user equipment wakes up the primary receiver. The offset between the end time of the LP-WUS listening period and the start time of the C-DRX duration timer is greater than or equal to the minimum duration. Before sending the LP-WUS, the user equipment receives the minimum duration sent by the user equipment.

[0214] There is another case where the user equipment 10a monitors the LP-WUS, but does not detect the LP-WUS (i.e., the user equipment misses the LP-WUS). In this case, the behavior of the user equipment 10a needs to be defined:

[0215] (1) Mode 1: The user equipment 10a monitors the PDCCH-based WUS by default, and decides whether to monitor the PDCCH next according to the PDCCH-based WUS.

[0216] In the example of FIG. 14 , when the user equipment does not receive the LP-WUS, it monitors the PDCCH-based WUS.

[0217] (2) Mode 2: Before step A2, the base station 20a configures a parameter to indicate the behavior of the user equipment 10a after not detecting LP-WUS. For example, the parameter is pre-configured to a first value (e.g., "0"), then in step A2, when the user equipment 10a does not detect LP-WUS, the user equipment 10a monitors the PDCCH-based WUS, and the user equipment 10a decides whether to start drx-onDurationTimer according to the PDCCH-based WUS; the parameter is pre-configured to a second value (e.g., "1"), then in step A2, when the user equipment 10a does not detect LP-WUS, the user equipment 10a does not monitor the PDCCH-based WUS, and the drx-onDurationTimer can be turned on by default;

[0218] In addition, when the short DRX cycle (drx-ShortCycle) is used, the solution in Example 1 is also applicable. When the long DRX cycle (Long DRX cycle) is used, the user equipment 10a first monitors the LP-WUS, determines whether to monitor the PDCCH-based WUS based on the LP-WUS, and then determines whether to monitor the next PDCCH based on the PDCCH-based WUS. When the short DRX cycle (Short DRX cycle) is used, the user equipment 10a adopts the method in Example 1.

[0219] In the example of FIG. 14 , when no LP-WUS is received, the user equipment determines whether to monitor the PDCCH-based WUS according to a first parameter, where the first parameter is used to indicate whether to monitor the PDCCH-based WUS.

[0220] It can be seen from the description that when the parameter indicates the configuration of the first value, the user equipment determines to monitor the PDCCH-based WUS, and decides whether to turn on the drx-onDurationTimer of the discontinuous reception C-DRX in the connected state to monitor the PDCCH according to the PDCCH-based WUS; and

[0221] When the parameter indicates configuring the second value, the user equipment determines not to monitor the PDCCH-based WUS, and may enable the drx-onDurationTimer of the discontinuous reception C-DRX in the connected state by default to monitor the PDCCH.

[0222] Example 3:

[0223] Regarding the impact of SR on LP-WUS, this embodiment provides the following solution. Referring to Figure 21, the process between the base station 20a and the user equipment 10a is roughly as follows:

[0224] Step B1: The base station 20a sends LP-WUS and SR-related parameters to the user equipment 10a. LP-WUS parameters may include LP-WUS time / frequency domain resources, LP-WUS period, etc. SR parameters may include SR period, offset within period, PUCCH resources used for SR transmission, maximum number of SR transmissions, SR prohibition timer, etc. LP-WUS parameters and SR parameters may be sent separately via RRC signaling. LP-WUS parameters and SR parameters may be sent simultaneously or separately, and there is no restriction on the order in which they are sent.

[0225] Step B2: The user equipment 10a may determine an LP-WUS monitoring timing based on the LP-WUS parameters, and the user equipment 10a monitors the LP-WUS at the LP-WUS monitoring timing. Accordingly, the base station 20a may send the LP-WUS to the user equipment 10a at the LP-WUS monitoring timing.

[0226] Step B3: The user equipment 10a may determine the timing of the SR based on the SR parameters and may send the SR to the base station 20a at the SR timing. Specifically, when the user equipment 10a has uplink data to transmit, the user equipment 10a triggers the SR, and the SR remains in a pending state. The user equipment 10a may send the SR to the base station 20a at the SR timing. Accordingly, the base station 20a receives the SR at the SR timing.

[0227] When the user equipment 10a sends a BSR or the uplink resources scheduled by the base station 20a are sufficient to carry the data to be transmitted, the pending state of the SR will be canceled.

[0228] In this embodiment, steps B2 and B3 are not in any particular order. SR and LP-WUS have the following situations:

[0229] 1)SR transmission comes first, LP-WUS comes later

[0230] Referring to Figure 22, the SR is transmitted first and the LP-WUS is transmitted later. After the user equipment 10a sends the SR (for example, in the next time slot after sending the SR), it needs to monitor the PDCCH. For the LP-WUS, the user equipment 10a can have one of the following behaviors:

[0231] a) After the user equipment 10a sends the SR (for example, in the next time slot after sending the SR) until the SR pending state is cancelled, the user equipment 10a does not monitor the LP-WUS, thereby saving terminal power consumption.

[0232] b) After the user equipment 10a sends the SR, until the pending state of the SR is cancelled, the user equipment 10a ignores the indication of the LP-WUS. That is, regardless of whether the LP-WUS indicates to monitor the PDCCH, the user equipment 10a still monitors the PDCCH. For example, one LP-WUS can be sent to multiple user equipments. Among them, UE1 and UE2 (for example, user equipment 10a and user equipment 10b) monitor the same LP-WUS, and the LP-WUS indicates not to monitor the PDCCH. However, after UE1 sends the SR, it ignores the indication of the LP-WUS and continues to monitor the PDCCH, while UE2 does not monitor the PDCCH according to the indication of the LP-WUS. In this way, the power consumption of other user equipment UE (UE2) is saved, and the user equipment (UE1) is guaranteed to be able to transmit data normally.

[0233] c) The user equipment 10a does not monitor the LP-WUS from the time the SR is triggered until the SR pending state is cancelled. The technical effect is the same as a).

[0234] d) From the time the SR is triggered until the pending state of the SR is cancelled, the UE 10a ignores the instruction of the LP-WUS. The technical effect is the same as b).

[0235] In the example of Figure 15, the uplink signal includes a scheduling request SR. During a third time period after triggering or sending the uplink signal, the user equipment does not monitor the low-power wake-up signal LP-WUS or ignores the indication of the low-power wake-up signal LP-WUS. The end time of the third time period is the moment when the pending SR is canceled. During a third time period after the user equipment triggers or sends the uplink signal, the base station determines that the user equipment does not monitor the low-power wake-up signal LP-WUS or ignores the indication of the low-power wake-up signal LP-WUS. The end time of the third time period is the moment when the pending SR is canceled.

[0236] Since base station 20a doesn't know when the user equipment triggers an SR, its understanding of the period from SR triggering to SR transmission differs from that of user equipment 10a. During this period, for solutions c) and d), even if base station 20a sends an LP-WUS instructing user equipment 10a not to monitor the PDCCH, user equipment 10a actually monitors the PDCCH. This has no impact on throughput and latency; it only increases power consumption during PDCCH monitoring.

[0237] 2) LP-WUS comes first, SR transmission comes later

[0238] Referring to Figure 23, for example, the user equipment detects an LP-WUS before sending an SR. When the user equipment 10a detects the LP-WUS, the LP-WUS instructs the user equipment 10a not to monitor the PDCCH. After detecting the LP-WUS, the user equipment has uplink traffic to transmit, and the user equipment 10a triggers an SR. After the user equipment 10a sends the SR (for example, in the next time slot after sending the SR), the user equipment 10a resumes PDCCH monitoring. Alternatively, after the SR is triggered, the user equipment 10a begins monitoring the PDCCH.

[0239] After the SR pending state is cancelled, the user equipment 10a may continue to monitor the LP-WUS and determine whether to monitor the PDCCH next according to the LP-WUS.

[0240] In the example of FIG15 , when the uplink signal includes a scheduling request (SR), the user equipment 10a receives the first LP-WUS, which indicates not to monitor the PDCCH. The user equipment 10a triggers or sends the uplink signal to monitor the Physical Downlink Control Channel (PDCCH). When the uplink signal includes a scheduling request (SR), the base station determines that the user equipment receives the first LP-WUS, which indicates not to monitor the PDCCH. The base station receives the uplink signal and determines that the user equipment monitors the Physical Downlink Control Channel (PDCCH).

[0241] Example 4:

[0242] Regarding the impact of the random access process on the LP-WUS, this embodiment provides the following solution. Referring to FIG24 , the process between the base station 20a and the user equipment 10a is described as follows:

[0243] Step C1: The base station 20a sends LP-WUS and PRACH-related parameters to the user equipment 10a. LP-WUS parameters may include LP-WUS time / frequency domain resources, LP-WUS period, etc. Random access includes 4-step random access and 2-step random access, and also includes contention-based random access and non-contention-based random access. This embodiment is not limited to any specific type of random access. Random access parameters include: preamble-related parameters, MSGA-related parameters, random access response time window length ra-ResponseWindow, contention resolution timer length ra-ContentionResolutionTimer, MSGB response time window length msgB-ResponseWindow, etc. LP-WUS parameters and random access parameters can be sent sequentially, with no restriction on the order.

[0244] Step C2: The user equipment 10a may determine an LP-WUS monitoring timing based on the LP-WUS parameters, and the user equipment 10a monitors the LP-WUS at the LP-WUS monitoring timing. Accordingly, the base station 20a may send the LP-WUS to the user equipment 10a at the LP-WUS monitoring timing.

[0245] Step C3: The user equipment 10a initiates a random access process. Specifically, the user equipment 10a sends MSG1 (also called PRACH, preamble) or MSGA (MSGA includes preamble and PUSCH) to the base station 20a.

[0246] For 4-step random access, after sending MSG1, the user equipment 10a monitors the RA-RNTI-scrambled DCI within the ra-ResponseWindow. The DCI schedules the PDSCH, which is used to transmit RAR (random access response) information. The content of the RAR includes the Timing Advance Command (TAC), uplink grant, and TC-RNTI. The user equipment 10a receives the RA-RNTI-scrambled DCI and the PDSCH scheduled by the DCI. The user equipment 10a also needs to send the PUSCH (i.e., MSG3) according to the uplink grant in the RAR. For contention-based random access, the user equipment 10a also needs to monitor the TC-RNTI-scrambled DCI during the ra-ContentionResolutionTimer. The DCI schedules the PDSCH, and the user equipment 10a receives the PDSCH according to the DCI.

[0247] For 2-step random access, after sending MSG A, the user equipment 10a monitors the DCI scrambled by MsgB-RNTI within the msgB-ResponseWindow. The DCI schedules the PUSCH.

[0248] Steps C2 and C3 are performed in no particular order. PRACH and LP-WUS have the following situations:

[0249] 1) PRACH transmission comes first, followed by LP-WUS. Figure 25 takes 4-step random access as an example.

[0250] After the user equipment 10a sends the preamble or MSGA (for example, the next time slot after sending the preamble), the user equipment 10a needs to receive the PDCCH within the ra-ResponseWindow, msgB-ResponseWindow, and ra-ContentionResolutionTimer. For LP-WUS, the user equipment 10a can have one of the following behaviors:

[0251] a) After the user equipment 10a sends the preamble or MSGA, the user equipment 10a does not monitor the LP-WUS, thereby saving terminal power consumption.

[0252] b) After the user equipment 10a sends the preamble or MSGA, the user equipment 10a ignores the instruction of the LP-WUS.

[0253] c) The user equipment 10a does not monitor for LP-WUS within the ra-ResponseWindow, msgB-ResponseWindow, and ra-ContentionResolutionTimer. When the random access procedure is a 4-step random access, the user equipment 10a does not monitor for LP-WUS within the ra-ResponseWindow and ra-ContentionResolutionTimer. When the random access procedure is a 2-step random access, the user equipment 10a does not monitor for LP-WUS within the msgB-ResponseWindow.

[0254] d) Within the ra-ResponseWindow, msgB-ResponseWindow, and ra-ContentionResolutionTimer, the user equipment 10a ignores the LP-WUS. When the random access procedure is a 4-step random access, the user equipment 10a ignores the LP-WUS within the ra-ResponseWindow and ra-ContentionResolutionTimer. When the random access procedure is a 2-step random access, the user equipment 10a ignores the LP-WUS within the msgB-ResponseWindow.

[0255] After the random access procedure is completed, for example, after the contention resolution is completed, the user equipment 10a may continue to monitor the LP-WUS.

[0256] 2) LP-WUS comes first, followed by PRACH transmission. Figure 26 takes 4-step random access as an example.

[0257] When the user equipment 10a detects an LP-WUS, the LP-WUS instructs the user equipment 10a not to monitor the PDCCH. After detecting the LP-WUS, the user equipment 10a sends a preamble or MSGA. When the random access procedure is a 4-step random access, the user equipment 10a needs to monitor the PDCCH within the ra-ResponseWindow and ra-ContentionResolutionTimer.

[0258] When the random access procedure is a two-step random access, the user equipment 10a needs to monitor the PDCCH within the msgB-ResponseWindow.

[0259] After the random access procedure is completed, for example, after contention resolution is completed, the user equipment 10a may continue to monitor the LP-WUS and determine whether to monitor the PDCCH next based on the LP-WUS.

[0260] In the example of Figure 15, when the uplink signal includes a preamble or msgA, the user equipment does not monitor the low power wake-up signal LP-WUS or ignores the indication of the low power wake-up signal LP-WUS within a fourth time period after sending the uplink signal. When the uplink signal includes a preamble or msgA, the base station determines that the user equipment does not monitor the low power wake-up signal LP-WUS or ignores the indication of the low power wake-up signal LP-WUS within a fourth time period after sending the uplink signal.

[0261] The fourth time period includes at least one of the following: a random access response window ra-ResponseWindow, a message B response window msgB-ResponseWindow, an operation period of a random access contention resolution timer ra-ContentionResolutionTimer, or a time slot from the next time slot for sending the uplink signal to the time slot when the random access process is completed.

[0262] When the uplink signal includes a preamble or msgA, the user equipment 10a receives the first LP-WUS, wherein the first LP-WUS indicates not to monitor the PDCCH. The user equipment 10a sends the uplink signal and monitors the physical downlink control channel (PDCCH) during the operation period of ra-ResponseWindow, msgB-ResponseWindow, or ra-ContentionResolutionTimer. When the uplink signal includes a preamble or msgA, the base station sends the first LP-WUS, wherein the first LP-WUS indicates not to monitor the PDCCH. The base station receives the uplink signal and determines that the user equipment monitors the physical downlink control channel (PDCCH) during the operation period of ra-ResponseWindow, msgB-ResponseWindow, or ra-ContentionResolutionTimer.

[0263] Example 5:

[0264] 27 , this embodiment provides the following solutions to address the impact of beam failure recovery (BFR) on LP-WUS:

[0265] Step D1: The base station 20a sends LP-WUS and BFR related parameters to the user equipment 10a. The BFR parameters include: PRACH-ResourceDedicatedBFR (PRACH resources used for BFR), recoverySearchSpaceId (index of the search space set used for BFR).

[0266] Step D2: The user equipment 10a monitors the LP-WUS at the LP-WUS monitoring opportunity. The base station 20a may send the LP-WUS to the user equipment 10a.

[0267] Step D3: The user equipment 10a sends a PRACH to the base station 20a.

[0268] Steps D2 and D3 are performed in no particular order. PRACH and LP-WUS have the following situations:

[0269] 1) PRACH transmission comes first, LP-WUS comes later

[0270] In the example of FIG15 , when the uplink signal includes a preamble, the user equipment 10a receives the signal from n+4+2 μ ·k mac The base station determines that when the uplink signal contains a preamble, the user equipment starts from n+4+2 μ ·k mac The time slot starts, and the low power consumption wake-up signal LP-WUS is not monitored or the indication of the low power consumption wake-up signal LP-WUS is ignored.

[0271] The n is the time slot where the preamble is located;

[0272] μ is the subcarrier spacing parameter of the PRACH used to transmit the preamble;

[0273] k mac is the number of time slots.

[0274] 28, for example, PRACH transmission comes first and LP-WUS comes later. The user equipment 10a sends 4+2 μ ·k mac The time slot starts (where μ represents the subcarrier spacing parameter of PRACH, for example, μ = 0 corresponds to a subcarrier spacing of 15Khz, and μ = 1 corresponds to a subcarrier spacing of 30Khz; k macIndicates the number of time slots, its value can be configured by RRC signaling, and the default value is 0), the user equipment 10a needs to receive the PDCCH scrambled by C-RNTI or MCS-C-RNTI according to the search space set corresponding to the parameter recoverySearchSpaceId. After the user equipment 10a receives the PDCCH scrambled by C-RNTI or MCS-C-RNTI according to the search space set corresponding to recoverySearchSpaceId, the user equipment 10a still needs to continue to receive the PDCCH scrambled by C-RNTI or MCS-C-RNTI according to the search space set corresponding to recoverySearchSpaceId until the user equipment 10a receives a MAC CE activation command, which indicates the transmission configuration indication state (Transmission Configuration Indicator state, TCI state), or receives tci-StatesPDCCH-ToAddList (TCI state add list) and / or tci-StatesPDCCH-ToReleaseList (TCI state release list).

[0275] In practical applications, the network typically sends the tci-StatesPDCCH-ToAddList and tci-StatesPDCCH-ToReleaseList to the user equipment 10a via an RRC message. The tci-StatesPDCCH-ToAddList may include one or more TCI states, and the tci-StatesPDCCH-ToReleaseList may include one or more TCI states. The TCI state is used to define the Quasi Co-Location (QCL) relationship between the downlink reference signal and the PDCCH's DMRS antenna port.

[0276] For BFR and LP-WUS monitoring, the user equipment 10a may have one of the following behaviors:

[0277] a) After the user equipment 10a sends the PRACH (for example, in the next time slot where the PRACH is located), the user equipment 10a does not monitor the LP-WUS, thereby saving terminal power consumption.

[0278] b) After the user equipment 10a sends the PRACH, the user equipment 10a ignores the indication of the LP-WUS.

[0279] c) The user equipment 10a is from n+4+2μ ·k mac Slot starts (n is the time slot where the PRACH is located), and the user equipment 10a does not monitor the LP-WUS.

[0280] d) The user equipment 10a is from n+4+2 μ ·k mac At the beginning of the slot, the user equipment 10a ignores the LP-WUS.

[0281] In the example of FIG15 , when the uplink signal includes a preamble, the user equipment receives the first LP-WUS, and the first LP-WUS indicates not to monitor the PDCCH. The user equipment sends the uplink signal. μ ·k mac The end time of each time slot is used as the starting point, and the user equipment monitors the physical downlink control channel PDCCH.

[0282] The base station determines that when the uplink signal includes a preamble, the user equipment receives the first LP-WUS, and the first LP-WUS indicates not to monitor the PDCCH. The base station receives the uplink signal. The base station determines that the 4+2 μ ·k mac The end time of each time slot is used as the starting point, and the user equipment monitors the physical downlink control channel PDCCH.

[0283] After the user equipment 10a receives a MAC CE activation command indicating a TCI state, or receives tci-StatesPDCCH-ToAddList and / or tci-StatesPDCCH-ToReleaseList, the user equipment 10a may continue to monitor the LP-WUS.

[0284] In the example of Figure 15 , the user equipment receives a media access control element MAC CE activation command, the MAC CE activation command indicating a TCI state, or receives tci-StatesPDCCH-ToAddList and / or tci-StatesPDCCH-ToReleaseList. The user equipment monitors a low power wake-up signal LP-WUS.

[0285] The base station sends a media access control element MAC CE activation command, where the MAC CE activation command indicates a TCI state, or sends tci-StatesPDCCH-ToAddList and / or tci-StatesPDCCH-ToReleaseList. The base station determines that the user equipment monitors a low power consumption wake-up signal LP-WUS.

[0286] 2) LP-WUS comes first, PRACH transmission comes later

[0287] Referring to FIG29, for example, LP-WUS is transmitted first and PRACH is transmitted later. When the user equipment 10a detects LP-WUS, LP-WUS instructs the user equipment 10a not to monitor PDCCH. After detecting LP-WUS, the user equipment 10a transmits PRACH. The 4+2 μ ·k mac slot, the user equipment 10a needs to receive the PDCCH scrambled by C-RNTI or MCS-C-RNTI according to the search space set corresponding to recoverySearchSpaceId. After the user equipment 10a receives the PDCCH scrambled by C-RNTI or MCS-C-RNTI according to the search space set corresponding to recoverySearchSpaceId, the user equipment 10a still needs to continue to receive the PDCCH scrambled by C-RNTI or MCS-C-RNTI according to the search space set corresponding to recoverySearchSpaceId until the user equipment 10a receives a MAC CE activation command indicating a TCI state, or receives tci-StatesPDCCH-ToAddList and / or tci-StatesPDCCH-ToReleaseList.

[0288] After the user equipment 10a receives a MAC CE activation command indicating a TCI state, or receives tci-StatesPDCCH-ToAddList and / or tci-StatesPDCCH-ToReleaseList, the user equipment 10a may continue to monitor the LP-WUS and determine whether to monitor the PDCCH next based on the LP-WUS.

[0289] Example 6:

[0290] Regarding the impact of CG PUSCH on LP-WUS, this embodiment provides the following solution. Referring to FIG30 , the process between the base station 20a and the user equipment 10a is described as follows:

[0291] Step E1: The base station 20a sends parameters related to LP-WUS and CG PUSCH to the user equipment 10a. The parameters of the LP-WUS may include the time / frequency domain resources of the LP-WUS, the period of the LP-WUS, etc. The parameters of the CG PUSCH may include parameters such as the period of the CG PUSCH, the number of HARQ processes, the number of repetitions, etc. CG PUSCH is divided into the first type of configuration authorization (type 1 CG) and the second type of configuration authorization (type 2 CG). For type 1 CG, the parameters of CG PUSCH also include the time / frequency domain resources of PUSCH. For type 2 CG, the time / frequency domain resources of CG PUSCH are scheduled through DCI (see the introduction of step E3). The parameters of the LP-WUS and the parameters of the CG PUSCH can be sent respectively through RRC signaling. The parameters of the LP-WUS and the parameters of the CG PUSCH can be sent simultaneously or separately, and there is no restriction on the order.

[0292] Step E2: The user equipment 10a may determine an LP-WUS monitoring timing based on the LP-WUS parameters, and the user equipment 10a may monitor the LP-WUS at the LP-WUS monitoring timing. Accordingly, the base station 20a may send the LP-WUS to the user equipment 10a at the LP-WUS monitoring timing.

[0293] Steps E2, E3, and E4 are performed in no particular order.

[0294] Step E3: The user equipment 10a may send a PUSCH to the base station 20a according to the parameters of the CG PUSCH. Correspondingly, the base station 20a receives the PUSCH according to the parameters of the CG PUSCH.

[0295] For type 1CG, the user equipment 10a can determine the PUSCH period and the time / frequency domain resources of the PUSCH based on the parameters of the CG PUSCH, and can periodically send the PUSCH to the base station 20a. For type 2 CG, before step E3, the base station 20a needs to send DCI to the user equipment 10a. The DCI is used to activate the CG PUSCH and indicate the time / frequency domain resources of the PUSCH. After the user equipment 10a receives the DCI, it executes step E3. That is, the user equipment 10a can periodically send the PUSCH to the base station 20a based on the period in the CG PUSCH parameters and the time / frequency domain resources of the PUSCH indicated by the DCI. Therefore, for the initial transmission of the CG PUSCH, the PUSCH resources are periodic. Except for the activation / deactivation DCI of the type 2 CG, the user equipment 10a does not need to receive DCI.

[0296] Step E4: For CG PUSCH retransmission, the user equipment 10a needs to receive DCI scrambled by the CS-RNTI. That is, if the base station 20a does not correctly receive the PUSCH, the base station 20a needs to send DCI to the user equipment 10a to trigger retransmission. Accordingly, the user equipment 10a does not know whether the base station 20a has correctly received the PUSCH, so the user equipment 10a still needs to monitor the DCI.

[0297] For CG PUSCH, there are the following situations:

[0298] 1) CG PUSCH in front, LP-WUS in the back

[0299] 31 , for example, CG PUSCH comes first and LP-WUS comes later. After the user equipment 10a sends the CG PUSCH, the user equipment 10a needs to monitor the retransmitted PDCCH. For LP-WUS, the user equipment 10a can have one of the following actions:

[0300] a) The user equipment 10a does not monitor LP-WUS for a period of time after sending the CG PUSCH, saving terminal power consumption. Specifically, the starting position, the ending position or the length of the period of time is predefined by the protocol or configured by the base station. For example, the starting position of the period of time is the Mth time slot after the CG PUSCH (M is greater than or equal to 0). For another example, the ending position of the period of time is the starting position or the ending position of the time unit where the user equipment 10a receives the DCI for scheduled retransmission (as shown in Figure 31). For another example, the length of the period of time is indicated to the user equipment 10a by the base station through RRC or MAC CE or DCI. For another example, if the user equipment 10a is also configured with C-DRX, the length of the period of time can be the drx-RetransmissionTimerUL running period.

[0301] b) The user equipment 10a ignores the LP-WUS indication for a period of time after sending the CG PUSCH. The length of this period of time can refer to the description in a) above.

[0302] After the period of time, the user equipment 10a may continue to monitor the LP-WUS and determine whether to continue to monitor the PDCCH according to an instruction of the LP-WUS.

[0303] 2) LP-WUS in front, CG PUSCH in the back

[0304] Referring to Figure 32 , for example, LP-WUS precedes CG PUSCH. When the user equipment 10a detects LP-WUS, the LP-WUS instructs the user equipment 10a not to monitor the PDCCH. After the user equipment 10a detects the LP-WUS, the user equipment 10a sends a CG PUSCH. Then, the user equipment 10a resumes monitoring the PDCCH for a period of time. The length of this period of time can refer to the description in a) above. After this period of time, the user equipment 10a may stop monitoring the PDCCH or continue to monitor the PDCCH. After this period of time, the user equipment 10a may resume monitoring the LP-WUS and determine whether to continue monitoring the PDCCH based on the instruction of the LP-WUS.

[0305] In the example of Figure 15, when the uplink signal includes a physical uplink shared channel CG PUSCH with a configuration grant, the user equipment does not monitor the low power wake-up signal LP-WUS or ignores the indication of the low power wake-up signal LP-WUS within a fifth time period after sending the uplink signal. The base station determines that when the uplink signal includes a physical uplink shared channel CG PUSCH with a configuration grant, the user equipment does not monitor the low power wake-up signal LP-WUS or ignores the indication of the low power wake-up signal LP-WUS within a fifth time period after sending the uplink signal.

[0306] The end time of the fifth time period is the start or end time position of downlink control information DCI, or the start or end time position of PUSCH, and the DCI is used to schedule the PUSCH; or

[0307] The fifth time period is the running period of drx-RetransmissionTimerUL.

[0308] In the example of FIG15 , when the uplink signal includes a Physical Uplink Shared Channel (CG PUSCH) with a grant configured, the user equipment 10a receives the first LP-WUS, which indicates not to monitor the PDCCH. The user equipment 10a transmits the uplink signal and monitors the Physical Downlink Control Channel (PDCCH). When the uplink signal includes a Physical Uplink Shared Channel (CG PUSCH) with a grant configured, the base station transmits the first LP-WUS, which indicates not to monitor the PDCCH. The base station receives the uplink signal and determines that the user equipment monitors the Physical Downlink Control Channel (PDCCH).

[0309] Example 7:

[0310] 33 , this embodiment illustrates the impact of BSR on LP-WUS.

[0311] Step F1: The base station 20a sends LP-WUS and BSR-related parameters to the user equipment 10a. LP-WUS parameters may include LP-WUS time / frequency domain resources, LP-WUS period, etc. BSR parameters may include BSR period, etc. The LP-WUS parameters and BSR parameters may be sent separately via RRC signaling. The LP-WUS parameters and BSR parameters may be sent simultaneously or separately, and there is no restriction on the order in which they are sent.

[0312] Step F2: The user equipment 10a may determine an LP-WUS monitoring timing based on the LP-WUS parameters, and the user equipment 10a may monitor the LP-WUS at the LP-WUS monitoring timing. Accordingly, the base station 20a may send the LP-WUS to the user equipment 10a at the LP-WUS monitoring timing.

[0313] Step F3: User equipment 10a sends a BSR to base station 20a. Specifically, a BSR is used to inform base station 20a of the amount of uplink data to be transmitted. Therefore, when user equipment 10a has uplink data to transmit, it sends a BSR to base station 20a. Upon receiving the BSR, base station 20a understands the amount of data to be transmitted. Furthermore, base station 20a may send DCI scheduling PUSCH resources to user equipment 10a.

[0314] In this embodiment, steps F2 and F3 are not in any particular order. BSR and LP-WUS have the following situations:

[0315] 1) BSR transmission comes first, LP-WUS comes later

[0316] After the user equipment 10a sends the BSR (for example, in the next time slot after sending the BSR), the user equipment 10a needs to monitor the PDCCH. For LP-WUS, the user equipment 10a may take one of the following actions:

[0317] a) After the BSR is sent from the user equipment 10a, the user equipment 10a does not monitor the LP-WUS for a period of time, thereby saving terminal power consumption. Specifically, the starting position, the ending position or the length of the period of time is predefined by the protocol or configured by the base station. For example, the starting position of the period of time is the Mth time slot (M is greater than or equal to 0) after the BSR is sent. For another example, the ending position of the period of time is the starting position or the ending position of the time unit where the user equipment 10a receives the DCI scheduling the PUSCH. For another example, the length of the period of time is indicated to the user equipment 10a by the base station through RRC or MAC CE or DCI.

[0318] b) After the user equipment 10a sends the BSR, the user equipment 10a ignores the LP-WUS indication for a period of time. The length of this period of time can be referred to the description in a) above.

[0319] 2) LP-WUS comes first, BSR transmission comes later

[0320] When the user equipment 10a detects an LP-WUS, the LP-WUS instructs the user equipment 10a not to monitor the PDCCH. After the user equipment 10a detects the LP-WUS, if there is uplink traffic to be transmitted, the user equipment 10a sends a BSR. After the user equipment 10a sends the BSR, the user equipment 10a may resume monitoring the PDCCH within a time period. The end position of this time period or the length of this time period is predefined by the protocol or configured by the base station. The length of this time period can refer to the description in a) above.

[0321] After the time period, the user equipment 10a may continue to monitor the LP-WUS and determine whether to monitor the PDCCH next according to the LP-WUS.

[0322] In the example of Figure 15, when the uplink signal includes a buffer status report BSR, the user equipment does not monitor the low power wake-up signal LP-WUS or ignores the indication of the low power wake-up signal LP-WUS within a sixth time period after the user equipment sends the buffer status report BSR. The base station determines that when the uplink signal includes a buffer status report BSR, the user equipment does not monitor the low power wake-up signal LP-WUS or ignores the indication of the low power wake-up signal LP-WUS within a sixth time period after the user equipment sends the buffer status report BSR.

[0323] When the uplink signal includes a buffer status report (BSR), the base station transmits the first LP-WUS, where the first LP-WUS indicates not to monitor the PDCCH. The base station receives the uplink signal and determines that the user equipment monitors a physical downlink control channel (PDCCH). When the uplink signal includes a buffer status report (BSR), the user equipment receives the first LP-WUS, where the first LP-WUS indicates not to monitor the PDCCH. The user equipment transmits the uplink signal and monitors the physical downlink control channel (PDCCH).

[0324] Example 8:

[0325] In addition to the uplink signals mentioned in embodiments 3 to 7, the uplink signals also include CSI, HARQ-ACK, and SRS. Referring to FIG34 , this embodiment illustrates the impact of LP-WUS on these three signals.

[0326] Step G1: The base station 20a may send an LP-WUS to the user equipment 10a. Accordingly, the user equipment 10a monitors the LP-WUS during the LP-WUS monitoring opportunity. The LP-WUS may be used to instruct the user equipment 10a not to wake up the primary receiver or not to monitor the PDCCH. Prior to step G1, the base station 20a may also send LP-WUS-related parameters to the user equipment 10a. The parameters may include the time / frequency location of the LP-WUS monitoring opportunity and the configurable LP-WUS period. The user equipment 10a may determine the LP-WUS monitoring opportunity based on the LP-WUS-related parameters.

[0327] Step G2: When the primary receiver is not awake or monitoring the PDCCH, there is uplink HARQ-ACK information, CSI or SRS to be transmitted. The following will discuss each of these separately:

[0328] a) HARQ-ACK: Since HARQ-ACK information is relatively important, the user equipment 10a can still report HARQ-ACK information when the primary receiver is not awake or is not monitoring the PDCCH.

[0329] b) CSI: The user equipment 10a may adopt one of the following methods, where the CSI is at least one of periodic CSI, semi-persistent CSI, and aperiodic CSI.

[0330] i. During the period when the main receiver is not awake or not monitoring the PDCCH, the user equipment 10a does not report CSI, saving terminal power consumption;

[0331] ii. During the period when the primary receiver is not awake or not monitoring the PDCCH, the user equipment 10a can still report CSI to ensure the accuracy of the channel state;

[0332] iii.
