Description

Method performed by user equipment and user equipment TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of wireless communication, and in particular, to a method performed by a user equipment for determining downlink resources and a corresponding user equipment. BACKGROUND

[0002] This section introduces aspects that can be helpful in understanding the various aspects of the present disclosure. Accordingly, the statements in this section are to be read in this light, and not as admissions of prior art or what is not prior art.

[0003] 5G systems can be used for mobile phones and various vertical applications. In addition to latency, reliability, availability, etc., energy efficiency of user equipment is one of the key elements for 5G. In current systems, user equipment usually consumes tens of milliwatts in RRC idle or inactive state and hundreds of milliwatts in RRC connected state. Depending on different application scenarios, user equipment can need to be charged every week or every day. Therefore, designs to further extend battery life are necessary to improve energy efficiency and achieve better user experience. For devices using miniature batteries or inconvenient to charge, such as sensors, automatic controllers, wearable devices, etc., the time for standby can be 1-2 weeks or longer, and it is more critical to improve energy efficiency.

[0004] User equipment can usually save power using discontinuous reception (DRX) mode, and power consumption depends on the length of the configured cycle, such as the length of the paging cycle. To meet the requirements of battery life, a DRX cycle with a very large cycle value can be applied, but this will result in high latency, which is not suitable for some scenarios. One scenario is an application scenario that requires both long battery life and low latency, such as fire detection and extinguishing devices, which have a response time of 1-2 seconds. Therefore, it is necessary to consider both the power saving of the device and the time requirement of the service processing.

[0005] In current systems, to ensure connectivity, user equipment needs to wake up periodically in each DRX cycle to detect control channels. Even when there is no data transmission for the user equipment, the user equipment still exists power consumption periodically. If the user equipment can only wake up when there is a service transmission requirement, the power consumption of the user equipment will be greatly reduced. Therefore, the user equipment can configure a low-power auxiliary receiver for detecting a wake-up signal (LP-WUS) sent by a base station. The main receiver of the user equipment can remain in a low-power state (e.g., sleep state) until the low-power receiver receives the LP-WUS signal and wakes up the main receiver for corresponding data processing. In this way, the service processing requirements of the user equipment can be met using less power consumption. To achieve such a design goal, there are several problems to be solved in the system, for example, in combination with DRX reception, different processing is used for the indication in the received LP-WUS in different DRX states to achieve compatibility with existing systems.

[0109] The following is a description of the technology associated with the present disclosure. Unless otherwise specified, the meanings of the same terms in the specific embodiments are the same as in the associated technology.

[0110] It is worth noting that the user equipment UE involved in the present disclosure is a device that communicates with a network device. The user equipment may also be described as a user, a terminal, etc. in the method used by the user equipment in the present disclosure, and these designations are not specifically distinguished and limited. The network device is a device that communicates with the user equipment, including but not limited to a wireless base station, a gNB, an eNB, a wireless AP, a wireless relay, a user equipment with relay capability, etc. The wireless base station can be used as a form of implementation of the network device in the present disclosure, and other forms of network devices can be easily used to replace the wireless base station in specific implementation.

[0111] In NR network, after a user equipment (UE) establishes a radio connection with a base station, it can enter a connected state (RRC_CONNECTED) and perform data transmission according to the configuration or scheduling of the base station. The base station can configure a DRX (discontinuous reception) function through RRC signaling to control the detection of PDCCH using certain MAC entity RNTIs by the connected UE, for example, to control the UE to detect the related PDCCH only when certain timers are running. These RNTIs include, but are not limited to, 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, SL-CS-RNTI, SL Semi-Persistent Scheduling V-RNTI, cellDTRX-RNTI, and the like. The DRX for the connected UE can also be referred to as C-DRX. When the connected UE is configured with DRX by the base station, the MAC entity can perform discontinuous PDCCH detection according to the related DRX procedure for all activated serving cells. The UE can determine the scheduling of the related PDSCH or PUSCH, or the activation or deactivation of the related PDSCH or PUSCH transmission, and the like, according to the DCI in the detected PDCCH.

[0112] Multiple serving cells in one MAC entity of a UE can be configured to at most two DRX groups, each of which uses some independent parameters and some common parameters. When two DRX groups are configured, the UE can determine that each serving cell belongs to one of the two DRX groups. When the second DRX group is not configured by RRC, the UE has only one DRX group, and all serving cells belong to this DRX group.

[0113] When the UE uses DRX, the parameters configured / used independently by each DRX group include drx-onDurationTimer and drx-InactivityTimer. The DRX group also uses several common parameters, such as drx-SlotOffset for determining the starting position of drx-onDurationTimer in the DRX cycle, drx-LongCycleStartOffse for determining the cycle period and starting offset of the long DRX cycle; downlink and uplink retransmission timers drx-RetransmissionTimerDL, drx-RetransmissionTimerUL, and the like.

[0114] The base station configures a drx-onDurationTimer parameter as a timing time for determining the timer drx-onDurationTimer. The UE can start the timer drx-onDurationTimer at the beginning of each DRX cycle, and the timing length is the value indicated by the drx-onDurationTimer parameter. For the convenience of description, the first time slot in which the UE can start the drx-onDurationTimer in each DRX cycle is referred to as a C-DRX time slot, or simply referred to as a DRX time slot.

[0115] When the base station configures the UE with DRX, the cells in the DRX group are in Active Time when the following conditions are met:

[0116] - the drx-onDurationTimer or drx-InactivityTimer configured for the DRX group is running; or

[0117] - the drx-RetransmissionTimerDL, drx-RetransmissionTimerUL or drx-RetransmissionTimerSL is running on any of the serving cells of the DRX group; or

[0118] - the timer ra-ContentionResolutionTimer or msgB-ResponseWindow for Random Access (RA) is running; or

[0119] - a Scheduling Request (SR) via PUCCH is transmitted and pending.

[0120] - a PDCCH indicating a new transmission related to C-RNTI has not been received, after successfully receiving a RAR, and the RAR is not related to a contention-based RA preamble; and so on.

[0121] If a DRX group is in Active Time, the UE can detect PDCCH on the serving cells of the DRX group, and perform relevant processing according to the information in the detected PDCCH, such as downlink / uplink data transmission, HARQ feedback, HARQ retransmission, and so on.

[0122] According to the relevant DRX operation process, the UE needs to perform PDCCH detection during the active time of the DRX. If the active time determined according to the relevant parameters configured by the base station is long, the UE needs to detect the PDCCH even if there is no data transmission, resulting in unnecessary power consumption. If the active time is short, the opportunity for the UE to use for data transmission is reduced, resulting in an increase in data transmission delay.

[0123] To further reduce the power consumption of the UE and reduce the delay, a feasible method is that the user equipment uses a low power receiver (LR) to detect the low power wake-up signal (LP-WUS) sent by the base station. When there is no data transmission, the main radio (MR) of the user equipment remains in a sleep state to minimize the power consumption of the user equipment; when there is data to be transmitted, the base station notifies the user equipment through the LP-WUS. When the user equipment detects the indication carried in the LP-WUS, the UE wakes up the MR and performs corresponding data processing. Hereinafter, the LP-WUS can also be referred to as WUS for short without detailed description. When the UE is implemented, different or shared components can be used to perform the relevant processing, for example, the LR is used to detect the LP-WUS, and the MR is used to detect the PDCCH. For ease of description, the UE can be used to describe the relevant LR or MR usage method and processing process in the present disclosure, and the UE can call the relevant components of the LR or the MR to perform the implementation according to the specific needs.

[0124] The indication information in one LP-WUS signal can include the indication information of multiple or multiple groups of user equipment, such as including different user equipment IDs, or indication bits of multiple UEs or UE groups, or sequences of different UEs or UE groups, and the like. The user equipment can determine the indication information corresponding to the user equipment or user group in the LP-WUS according to a certain method. For example, when the LP-WUS provides the indication information in the form of a bit map, the UE can determine the bit position of the indication information of the user equipment or user group according to the relevant parameters, and use bit 1 to indicate that the UE detects PDCCH or starts the relevant timer in the relevant process; use bit 0 to indicate that the UE does not detect PDCCH or does not start the relevant timer in the relevant process. For another example, when the LP-WUS provides the indication information in the form of a sequence, there is a specific sequence related to the UE in the LP-WUS, which is used to indicate that the UE detects PDCCH or starts the relevant timer in the relevant process; there is no specific sequence related to the UE in the LP-WUS, which is used to indicate that the UE does not detect PDCCH or does not start the relevant timer in the relevant process. There can be other ways to determine the indication information of the user equipment or user group in the actual system, which are not limited here. In this disclosure, for the sake of simplicity of description, the indication according to the LP-WUS is the indication according to the indication corresponding to the UE or UE group in the LP-WUS. In addition, the indication for indicating the action of the UE detecting PDCCH or starting the relevant timer can be referred to as positive indication, and vice versa.

[0125] The LP-WUS signal can use the waveform of OOK (On-Off keying) for transmission to reduce the complexity of the receiver. In order to be compatible with existing NR devices, OOK can be generated in a manner compatible with OFDM symbols, such as using multi-carrier OOK. At this time, on the bandwidth of the LP-WUS signal, an integer number of OOK symbols can be contained in one OFDM symbol length, such as 1 / 2 / 4 / 8 / 16, etc., so that the base station is easy to implement signal transmission of different waveforms. Therefore, the length of the time domain resource used by the related LP-WUS in the time domain can also be described using the parameters of the number of OFDM symbols, the number of slots, the number of frames, and the like.

[0126] When UE uses LP-WUS, UE can use different procedures to implement the cooperation with other channels and configurations according to the configuration and indication of network. For example, when UE is configured with DRX, UE detects LP-WUS before C-DRX slot and determines whether to start drx-onDurationTimer of a DRX cycle according to the indication in LP-WUS; or detects LP-WUS outside DRX active time and determines whether to detect PDCCH according to the indication in LP-WUS to reduce the latency of data transmission while keeping the low power consumption of UE; or detects LP-WUS within DRX active time and determines whether to detect PDCCH and receive PDSCH according to the indication in LP-WUS to more accurately indicate the data arrival time and reduce the power consumption of UE. In addition, if the connected UE is not configured with DRX, UE can also determine the detection of PDCCH according to the indication of LP-WUS. In summary, the base station can configure the relevant LP-WUS resources for UE, and the connected UE determines the relevant processing according to the detection of LP-WUS and the indication of LP-WUS to reduce the power consumption of UE and improve the user experience.

[0127] UE detects LP-WUS on a plurality of time-frequency resources determined according to the LP-WUS parameters configured by the base station. These time-frequency resources used to detect LP-WUS can be referred to as a plurality of LP-WUS monitoring occasions (LP-WUS MO, or simply LMO) of LP-WUS. FIG. 1 is a specific example, in (a) of FIG. 1, UE determines the positions of a plurality of possible transmissions of LP-WUS in time domain according to the period P of LP-WUS, i.e., the LMOs used by UE to detect LP-WUS. In (b) of FIG. 1, the base station can configure a plurality of LP-WUS resources, for example, each resource uses different TCI information parameters, respectively, and satisfies the QCL relationship with the reference signal SSB or CSI-RS or PDCCH using different beams. UE can determine the LMOs corresponding to the plurality of LP-WUS according to the periods P1, P2 of LP-WUS, respectively.

[0128] The base station can configure LP-WUS resources for different procedures or functions to indicate UE to perform the relevant processing. In order to enable UE to correctly determine the relevant processing according to the detection results on these LP-WUS, these LP-WUS for different procedures or functions can be divided into different sets, or the relevant LMOs belong to different sets, respectively. These sets can also be referred to as other names, such as LP-WUS detection space, LMO detection space, LP-WUS function set, etc., and the LMO set can be used in this disclosure to refer to these LP-WUS for a certain procedure or function and the corresponding set of LMOs.

[0129] Based on the related design in the disclosure, there are several problems to be solved when applying LP-WUS in the network, such as how to coordinate the processing of LP-WUS and DRX related processes, how to distinguish LP-WUS for different functions and its detection opportunity, how to determine whether to detect LP-WUS, etc. The disclosure provides related methods to solve the above problems, so that the user equipment can obtain better power saving effect through the mutual cooperation of the base station and the user equipment.

[0130] The following embodiments are provided to describe the embodiments of the disclosure in more detail.

[0131]

Embodiment 1

[0132] FIG. 2 is a flowchart of a method performed by a user equipment UE according to an aspect of an embodiment of the disclosure.

[0133] The method of the embodiment is a method performed by a user equipment UE in a connected state, as shown in FIG. 2, including the following steps: the UE determines a first LMO set associated with a discontinuous reception DRX cycle (step S201);

[0134] The UE determines a second LMO set different from the first LMO set (step S202);

[0135] The UE determines the detection of a physical downlink control channel PDCCH according to the indication in the LP-WUS detected by the first LMO set or the second LMO set (step S203).

[0136] The order of step S201 and step S202 can be exchanged. That is, the UE can first determine a second LMO set associated with a discontinuous reception DRX cycle, and then determine a first LMO set different from the second LMO set.

[0137] The related processes are described in detail below.

[0138] In NR network, for a user equipment in connected state, the base station can configure LP-WUS resource for indicating UE's processing. UE can detect LP-WUS according to the related configuration, and determine the related processing according to the indication in LP-WUS. When UE is configured with C-DRX, UE can detect the indication in LP-WUS at different time determined according to C-DRX parameters, to implement different functions. For example, UE determines whether to start the related timer drx-onDurationTimer in the DRX cycle according to the indication in LP-WUS detected before starting the related timer in the DRX cycle, and performs PDCCH detection when the timer drx-onDurationTimer is running. In another case, UE can detect LP-WUS outside the DRX active time. When detecting LP-WUS, UE performs the related processing according to the indication in LP-WUS, for example, starts a timer WUS-ActiveTimer1 according to the indication that a timer can be started, and performs PDCCH detection when the timer is running; or directly performs PDCCH detection in the related time slot according to the indication. In another case, UE can detect LP-WUS within the DRX active time. When detecting LP-WUS, UE performs the related processing according to the indication in LP-WUS, for example, starts a timer WUS-ActiveTimer2 according to the indication that a timer can be started, and performs PDCCH detection when the timer is running. The timing time of timer WUS-ActiveTimer1 or WUS-ActiveTimer2 can be different from drx-onDurationTimer, for example, can be shorter, so that the base station can more accurately schedule the data transmission of UE, and reduce the power consumption of UE.

[0139] In one embodiment, the base station configures the UE with a set of LP-WUS parameters, e.g., including the frequency domain location and bandwidth information of the LP-WUS resources, the time domain symbol length, etc. The UE can determine a number of LMOs according to the LP-WUS parameters. The UE can determine the set of LMOs in a C-DRX cycle according to certain methods, e.g., determine a first set of LMOs and a second set of LMOs in a DRX cycle, and determine the related processing according to the indication in the LP-WUS detected in the first set of LMOs or the second set of LMOs, respectively. For example, if the UE detects the LP-WUS in the first set of LMOs, the UE starts the related timer drx-onDurationTimer according to the positive indication in the LP-WUS, and performs the PDCCH detection when the drx-onDurationTimer is running. If the UE detects the LP-WUS in the second set of LMOs, the UE performs the related processing according to the indication in the LP-WUS, e.g., starts a timer WUS-ActiveTimer according to the positive indication, and performs the PDCCH detection when the timer is running. In this way, the UE can reduce the transmission latency and the power consumption of the UE while being compatible with the existing network configuration.

[0140] One embodiment is shown in FIG. 3. In this embodiment, the UE determines whether to start the related timer drx-onDurationTimer according to the indication in the LP-WUS detected in the first set of LMOs, and the UE determines whether to start the timer WUS-ActiveTimer according to the indication in the LP-WUS detected in the second set of LMOs.

[0141] Optionally, the UE determines the first set of LMOs associated with a DRX cycle according to one of the following methods:

[0142] the N consecutive LMOs satisfying the first offset before the C-DRX slot;

[0143] the LMO satisfying between the first offset and the second offset before the C-DRX slot;

[0144] the LMO with a certain or certain sequence number in the DRX cycle;

[0145] the LMO satisfying between the second offset and the C-DRX slot before the C-DRX slot.

[0146] The offset in the first offset and the second offset herein represents a length of several slots / symbols. The offset herein can also be referred to by different names, such as interval or distance, etc. The interval between the slot or symbol where the LMO is located and the C-DRX slot or the first symbol of the C-DRX slot is greater than or equal to the length corresponding to the first or second offset, to meet the first or second offset representing the LMO. Here, the unit of the length and the interval can be one of the parameters such as slot or symbol or millisecond or radio frame, etc.

[0147] For example, the slot where the LMO is located can be one of the following:

[0148] - the first slot used by the LMO;

[0149] - the last slot used by the LMO.

[0150] For example, the symbol where the LMO is located can be one of the following:

[0151] - the first symbol used by the LMO;

[0152] - the last symbol used by the LMO;

[0153] - the first symbol of the first slot used by the LMO;

[0154] - the last symbol of the last slot used by the LMO.

[0155] Optionally, the first offset is a high-layer configured value, for example, the time corresponding to the first offset includes the time for the UE to process the reception of the LP-WUS, the MR state transition time, the time-frequency synchronization time required by the MR, etc. The base station can configure a first offset for the UE through a high-layer parameter, so that the UE has enough time to wake up the MR for related processing when detecting the LP-WUS.

[0156] Optionally, the first offset is a predefined value determined by the UE according to related parameters, for example, the UE determines from a predefined table according to the SCS used by the LP-WUS, or the UE determines from a predefined table according to the SCS used by the LP-WUS and the reported capability parameter of the UE.

[0157] Optionally, the first offset is a fixed value, for example, 0. For example, the UE does not report the minimum offset value required, and the high layer does not configure the first offset value, and the UE can use the fixed value as the first offset value.

[0158] Optionally, the second offset is a high-layer configured value, for example, in addition to the various processing times considered in the first offset, the time corresponding to the second offset also includes the time required for transmitting several LP-WUS. For example, the base station can configure the second offset through an RRC parameter for the UE to determine the related LMO.

[0159] Optionally, UE can determine the size of N according to related parameters. For example, N = N1*N2, where N1 is the number of LP-WUS using different TCI information, which can be determined by UE according to the number of different TCI information in the configured LP-WUS resource parameters; N2 is the time domain repetition number configured by high layer. Optionally, when the time domain repetition number is not configured, N2 can use the default value of 1.

[0160] Optionally, the sequence number when UE determines the first LMO set according to the LMO of certain sequence number(s) in the DRX cycle is the value configured by high layer. For example, the related sequence number value is determined by one or more sequence number parameters configured by high layer.

[0161] After UE determines the first LMO set, the LMO not belonging to the first LMO set determined according to the LP-WUS parameter configuration can be determined as the second LMO set.

[0162] TCI information can be used in the network to indicate the spatial parameter information used by PDCCH or LP-WUS. TCI information can contain multiple parameters, such as the sequence number of the reference signal, the cell where the reference signal is located, the type of QCL, etc. The TCI information used by PDCCH can be configured by related CORESET parameters. When multiple TCI information is configured, it can also be determined according to the indication of MAC signaling which TCI information to use. When no TCI information is configured, UE can obtain the TCI information used by PDCCH according to some default method, such as the SSB sequence number used during random access, etc. The base station can configure LP-WUS for certain PDCCH or certain type of PDCCH, which is used to indicate the detection of the PDCCH.

[0163] For example, UE determines whether to detect the related PDCCH according to the indication in the LP-WUS detected on the LMO. The RNTI used by PDCCH includes but is not limited to 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, SL-CS-RNTI, SL Semi-Persistent Scheduling V-RNTI, cellDTRX-RNTI, etc. Here the correlation between one LMO or LP-WUS and PDCCH can be one of the following relationships:

[0164] -LMO or LP-WUS uses the same TCI information as PDCCH;

[0165] - LMO or LP-WUS uses the same reference signal as PDCCH, e.g. SSB with the same ID or order or CSI-RS with the same ID or order;

[0166] - LMO or LP-WUS is associated to PDCCH by RRC signaling, e.g. associating LP-WUS resource ID to search space configuration or CORESET configuration used by PDCCH.

[0167] Wherein the TCI information or reference signal used by PDCCH can be determined by UE according to default manner or configuration or indication by base station.

[0168] Optionally, UE determines a first LMO set associated to PDCCH for a DRX cycle according to one of the following methods:

[0169] - N consecutive LMOs associated to PDCCH satisfying a first offset before C-DRX slot;

[0170] - LMO associated to PDCCH satisfying between a first offset and a second offset before C-DRX slot;

[0171] - LMO associated to PDCCH satisfying between a second offset and C-DRX slot before C-DRX slot.

[0172] Herein, the offset in the first offset and the second offset means a length of time slot or symbol, or can be called as interval or distance, etc. Satisfying the first or second offset means the interval between the time slot or symbol where LMO is located and the C-DRX slot or the first symbol of C-DRX slot is larger than or equal to the length corresponding to the first or second offset. Herein, the unit of length and interval can be one of time slot, symbol, millisecond, radio frame, etc.

[0173] For example, the time slot where LMO is located can be one of the following:

[0174] - the first time slot used by LMO;

[0175] - the last time slot used by LMO.

[0176] For example, the symbol where LMO is located can be one of the following:

[0177] - the first symbol used by LMO;

[0178] - the last symbol used by LMO;

[0179] - the first symbol of the first time slot used by LMO;

[0180] - the last symbol of the last slot used by the LMO.

[0181] wherein, optionally, the first offset is a higher layer configured value, e.g., the time corresponding to the first offset contains UE’s time for processing the reception of the LP-WUS, MR state transition time, MR’s time for time and frequency synchronization, etc. The network base station can configure a first offset for the UE through a higher layer parameter, so that the UE has enough time to perform relevant processing with the wake-up MR when detecting the LP-WUS.

[0182] Optionally, the first offset is a predefined value determined by the UE according to relevant parameters, e.g., the UE determines from a predefined table according to the SCS used by the LP-WUS, or the UE determines from a predefined table according to the SCS used by the LP-WUS and the UE’s reported capability parameter.

[0183] Optionally, the first offset is a fixed value, e.g., 0. For example, the UE does not report the minimum offset value required, and the higher layer does not configure the first offset value, the UE can use the fixed value as the first offset value.

[0184] Optionally, the second offset is a higher layer configured value, e.g., the time corresponding to the second offset contains the time required for transmitting a number of LP-WUSes in addition to the various processing times considered in the first offset. For example, the base station can configure the second offset through an RRC parameter for the UE to determine the relevant LMO.

[0185] Optionally, the UE can determine the size of N according to relevant parameters. For example, N = N1*N2, where N1 is the number of LP-WUSes using different TCI information, which can be determined by the UE according to the number of different TCI information in the configured LP-WUS resource parameters; N2 is the time domain repetition number configured by the higher layer. Optionally, when the time domain repetition number is not configured, N2 can use a default value of 1.

[0186] Optionally, the sequence number when the UE determines the first LMO set according to the LMO of a certain sequence number or certain sequence numbers in the DRX cycle is a higher layer configured value. For example, the relevant sequence number value is determined through one or more sequence number parameters configured by the higher layer.

[0187] After the UE determines the first LMO set, the UE can determine the LMOs not belonging to the first LMO set and related to the PDCCH according to the LP-WUS parameter configuration as the second LMO set.

[0188] Another aspect of the present disclosure, the UE can also determine a second LMO set associated with a DRX cycle according to one of the following methods:

[0189] - LMOs starting from the first symbol of the C-DRX slot and continuing for NN symbols;

[0190] - LMOs on KK time units starting from the first symbol of the C-DRX slot;

[0191] - LMOs from the first symbol of the C-DRX slot to the slot or symbol that meets the third offset with the next C-DRX slot.

[0192] The offset in the third offset here means the length of several slots / symbols, and different names such as interval or distance, etc. can also be used. The meeting of the third offset means that the interval between the slot or symbol and the C-DRX slot or the first symbol of the C-DRX slot is greater than or equal to the length corresponding to the third offset, and the unit of the length and the interval can be slots or symbols or milliseconds, etc.

[0193] Wherein, optionally, the third offset is a high-layer configured value, for example, the time corresponding to the third offset contains the time for the UE to process the reception of the LP-WUS, the MR state transition time, the time required for the MR to synchronize, the transmission time of a number of LP-WUS, etc. The network can configure a third offset for the UE, so that the UE has enough time to use the MR to perform related processing when detecting the LP-WUS.

[0194] Optionally, KK is a high-layer configured value, and the time unit used can be one of slots, symbols, milliseconds, or radio frames.

[0195] Optionally, the UE can determine the size of NN according to related parameters. For example, NN = N1*N2*N3, where N1 is the number of LP-WUSs using different TCI information, which can be determined by the UE according to the number of different TCI parameters related to the configured LP-WUS resource; N2 is the time domain repetition number configured by the high-layer parameter. When the time domain repetition number is not configured, N2 uses the default value of 1. N3 is the number configured by the high-layer parameter.

[0196] Optionally, after the UE determines the second LMO set, the LMOs determined according to the LP-WUS parameter configuration and not belonging to the second LMO set can be determined as the first LMO set.

[0197] Optionally, after the UE determines the second LMO set, the LMOs determined according to the LP-WUS parameter configuration and not belonging to the second LMO set and having a distance greater than the first offset from the next DRX slot can be determined as the first LMO set.

[0198] Optionally, the UE also determines a second LMO set of a DRX cycle according to the relevance to the PDCCH. For example, the UE determines a second LMO set of a DRX cycle according to one of the following methods:

[0199] - the LMOs relevant to the PDCCH starting from the first symbol of the C-DRX slot and continuing for NN symbols;

[0200] - the LMOs relevant to the PDCCH in the KK time units starting from the first symbol of the C-DRX slot;

[0201] - the LMOs relevant to the PDCCH from the first symbol of the C-DRX slot to the slot or symbol satisfying the third offset to the next C-DRX slot;

[0202] Optionally, the third offset is a high-layer configured value, for example, the time corresponding to the third offset contains the time for the UE to process the reception of the LP-WUS, the MR state transition time, the time-frequency synchronization time required by the MR, the transmission time of a number of LP-WUS, etc. The network can configure a third offset for the UE, so that the UE has enough time to perform relevant processing using the MR when detecting the LP-WUS.

[0203] Optionally, KK is a high-layer configured value, and the time unit used can be one of a slot, a symbol, or a millisecond, or a radio frame.

[0204] Optionally, the UE can determine the size of NN according to relevant parameters. For example, NN = N1*N2*N3, where N1 is the number of LP-WUSs using different TCI information, which can be determined by the UE according to the number of different TCI parameters related to the configured LP-WUS resource; N2 is the time domain repetition number configured by the high-layer parameter. When the time domain repetition number is not configured, N2 uses a default value of 1. N3 is the number configured by the high-layer parameter.

[0205] Optionally, the sequence number when the UE determines the second LMO set according to the LMO of a certain sequence number or a certain sequence number in the DRX cycle is a high-layer configured value.

[0206] Optionally, the sequence number when the UE determines the second LMO set according to the LMO of a certain sequence number or a certain sequence number in the DRX cycle is a default value.

[0207] After the UE determines the second LMO set, the UE determines the first LMO set according to the LMOs not belonging to the second LMO set and relevant to the PDCCH, which are determined according to the LP-WUS parameter configuration.

[0208] When the UE determines whether to perform PDCCH detection according to the indication in the LP-WUS detected on the LMO, it can do so according to certain methods. For example, the UE determines PDCCH detection according to a positive indication in the LP-WUS detected on the LMO according to one of the following methods:

[0209] - The UE directly detects PDCCH on the relevant time slot; for example, the UE performs PDCCH detection on the N time slots after the M time slots of the LMO in which the LP-WUS is received; or the UE performs relevant PDCCH detection on the N time slots after the M time slots of the LMO in which the LP-WUS is received; optionally, M and N can be high-layer configuration values. Optionally, M is the first offset value described above.

[0210] - The UE starts a relevant timer, and during the running of the timer, the UE detects PDCCH. For example, the UE starts the relevant timer drx-onDurationTimer or WUS-ActiveTimer on the DRX time slot related to the LMO; for another example, the UE starts the timer WUS-ActiveTimer after the M time slots of the LMO in which the LP-WUS is received.

[0211] Here, the M or N time slots can also use other time units, such as symbols, radio frames, milliseconds, etc., which will not be described one by one here.

[0212] In another aspect of the disclosure, the UE can determine one or more different processing according to the indication in the LP-WUS configured by the network. For example, the UE can detect the LP-WUS in a determined first LMO set according to the configuration of the base station, and determine whether the UE starts the drx-onDurationTimer in the associated DRX cycle according to the indication in the LP-WUS. The UE can also determine a third LMO set, e.g., the LMO set within the C-DRX active time, according to the configuration of the base station, and the UE can detect the LP-WUS on the third LMO set. When the LP-WUS is detected, the UE performs the relevant action according to the relevant indication, e.g., can start a timer WUS-ActiveTimer, and perform the PDCCH detection when the timer is running. The UE can also determine a second LMO set, e.g., the LMO set outside the C-DRX active time, according to the configuration of the base station. If the UE detects the LP-WUS on the second LMO set, the UE performs the relevant action according to the relevant indication in the LP-WUS, e.g., can start a timer WUS-ActiveTimer, and perform the PDCCH detection when the timer is running. The UE can determine the different LMO sets according to the method in the disclosure, or determine the different LMO sets from the different LP-WUS configurations according to the higher layer configuration. The UE needs to determine the relevant processing when there are multiple LMO sets to avoid conflicts and improve system efficiency.

[0213] Optionally, the UE determines that when the first LMO set and the second LMO set exist at the same time, if one LMO of the second LMO set meets one of the following conditions, the UE does not detect the LMO:

[0214] - there is an overlap with the running drx-onDurationTimer, which is started according to the indication in the LP-WUS detected on the first LMO set; or

[0215] - there is an overlap with the running WUS-ActiveTimer, which is started according to the indication in the LP-WUS detected on the first LMO set; or

[0216] - there is an overlap with the active time;

[0217] Optionally, the UE determines the related processing according to whether the first LMO set and the third LMO set exist simultaneously, and the indication in the LP-WUS. For simplicity of description, the indication determined by the UE according to the detected LP-WUS on the first LMO set can be referred to as the first indication. The first indication can be a positive indication or a negative indication. For example, the positive indication is represented by '1', and the negative indication is represented by '0'. When the UE detects the indication of the LP-WUS on the first LMO set, the first indication is determined to be the positive indication or the negative indication according to the indication in the LP-WUS.

[0218] Optionally, when the UE does not detect the indication of the LP-WUS on the first LMO set associated with one DRX cycle, the UE can use the parameter value of the positive indication or the negative indication configured by the higher layer as the value of the first indication. Optionally, if the higher layer does not configure the parameter value for the first indication, the default value can be determined, for example, the negative indication can be used by default.

[0219] Optionally, if the first and third LMO sets are configured, the UE determines the detection of the UE on the third LMO set according to the first indication. When the first indication is the positive indication, the UE detects the LP-WUS on the third LMO set. And the UE performs the detection of the PDCCH according to the LP-WUS detected on the third LMO set, when the LP-WUS is detected, the UE performs the related action according to the related indication, for example, a timer WUS-ActiveTimer can be started, and the detection of the PDCCH is performed when the timer is running. When the first indication is the negative indication, the UE does not detect the LP-WUS on the third LMO set in the corresponding DRX cycle, and the detection of the PDCCH is not performed according to the indication of the LP-WUS in the DRX cycle.

[0220] Optionally, if the first and third LMO sets are configured, the UE determines the detection of the UE on the third LMO according to the first indication. When the first indication is the positive indication, the UE starts the corresponding timer (for example, the drx-onDurationTimer), and detects the PDCCH when the timer is running (and during the active time); the UE does not detect the LP-WUS on the third LMO set in the related DRX cycle. When the first indication is the negative indication, the UE detects the LP-WUS on the third LMO set in the related DRX cycle, and can perform the detection of the PDCCH according to the indication of the LP-WUS, for example, a timer WUS-ActiveTimer can be started, and the detection of the PDCCH is performed when the timer is running.

[0221] Optionally, the UE determines the related processing according to whether the first and third LMO sets are configured simultaneously. For example, if the first and third LMO sets are configured, and the UE detects a positive indication of the LP-WUS on the first LMO set, the UE can start a second timer (e.g., WUS-ActiveTimer) according to the indication, and perform the PDCCH detection according to the timer, and the UE performs the LP-WUS detection on the third LMO set of the DRX cycle. If the UE does not detect the indication of the LP-WUS on the first LMO set or detects a negative indication, the UE performs the LP-WUS detection on the third LMO set of the DRX cycle, and performs the PDCCH detection according to the indication of the detected LP-WUS, e.g., a timer WUS-ActiveTimer can be started when a positive indication is detected, and the PDCCH detection is performed when the timer is running. If the UE is not configured with the third LMO set, only the first LMO set is configured, and the UE detects the indication of the LP-WUS on the first LMO set, the UE can start a first timer (e.g., drx-onDurationTimer) according to the indication, and perform the PDCCH detection when the timer is running.

[0222] Optionally, if the LMO overlaps with a running timer (e.g., WUS-ActiveTimer) when the UE performs the detection on the third LMO set of a DRX cycle, the UE does not need to perform the LP-WUS detection on the LMO.

[0223] Optionally, if a positive indication is detected when the UE performs the detection on the third LMO set of a DRX cycle, the UE does not need to perform the LP-WUS detection on the LMOs of the remaining third LMO sets of the DRX cycle.

[0224] Optionally, if a positive indication is detected when the UE performs the detection on the third LMO set of a DRX cycle, the UE determines whether to perform the LP-WUS detection on the LMOs of the remaining third LMO sets of the DRX cycle according to the indication of the higher layer. For example, if the higher layer indicates to perform the detection, the UE performs the LP-WUS detection on the LMOs of the remaining third LMO sets of the DRX cycle, otherwise the UE does not need to perform the LP-WUS detection on the LMOs of the remaining third LMO sets of the DRX cycle.

[0225] According to another aspect of the disclosure, when the base station uses the indication of the UE in the LP-WUS to indicate the related processing, the base station can use an OOK signal to transmit the related LP-WUS, for example, using the ON and OFF states of the OOK to represent '1' and '0'. At the same time, when the base station transmits the related OOK signal, the base station can also transmit some additional information on the resources used by the OOK signal. For example, when the base station transmits the symbol '1' of the OOK, the base station uses a specific sequence, and the UE can determine different indication information according to different sequences. For the sake of simplicity of description, the information determined by the UE according to the ON / OFF state of the OOK symbol in one LP-WUS can be referred to as first information, and the information determined by the UE according to the ON / OFF state of the non-OOK symbol can be referred to as second information. The UE can report its capability to the base station, for example, the capability of detecting the first information according to the LP-WUS (referred to as capability 1) or the capability of detecting the first and second information according to the LP-WUS (referred to as capability 2). The UE can determine the related processing according to the indication in the LP-WUS and the capability reported by the UE. For a specific example, when the UE uses the indication in the LP-WUS to determine whether to perform PDCCH detection or start the related timer, the UE can also determine the related processing according to the following method:

[0226] - When the UE reports the capability to the base station as capability 2, if the UE determines that the indication information of the UE or the group to which the UE belongs in the first information is '1' and the UE determines that the indication information of the UE or the group to which the UE belongs in the second information is '1', the UE reports to the higher layer (MAC layer) that the timer drx-onDurationTimer is started in the associated DRX cycle; if the UE determines that the indication information of the UE or the group to which the UE belongs in the first information is '0' or the UE determines that the indication information of the UE or the group to which the UE belongs in the second information is '0', the UE reports to the higher layer (MAC layer) that the timer drx-onDurationTimer is not started in the associated DRX cycle.

[0227] - When the UE reports the capability to the base station as capability 1, if the UE determines that the indication information of the UE or the group to which the UE belongs in the first information is '1', the UE reports to the higher layer (MAC layer) that the timer drx-onDurationTimer is started in the associated DRX cycle; if the UE determines that the indication information of the UE or the group to which the UE belongs in the first information is '0', the UE reports to the higher layer (MAC layer) that the timer drx-onDurationTimer is not started in the associated DRX cycle.

[0228] In this way, UEs with different capabilities can multiplex the indication of a certain UE or UE group in the LP-WUS, thereby reducing the system overhead of the LP-WUS and improving the system performance.

[0229] Embodiment 2

[0230] The LP-WUS signal can use OOK (on-off keying) modulation to generate the signal to simplify the receiver structure, and in general, the link performance is worse than that of an OFDM signal using the same power spectral density, that is, the downlink coverage of the LP-WUS is smaller than that of other channels using OFDM such as PDCCH when using the same downlink power. In addition, the LR in different terminals for receiving the LP-WUS can have different capabilities, such as some LR having a relatively high NF (Noise figure) compared to the MR, which can also cause the link performance of the LR receiving the LP-WUS to be worse than the performance of the MR receiving other channels. Different UEs can also have different capabilities, for example, some UEs can use the carrier signal in the OOK modulated signal of the LP-WUS to obtain better reception performance, and so on. At this time, the network can instruct the UEs with different capabilities to use different modes to receive the LP-WUS signal. On the other hand, the network can also improve the downlink reception performance of the LP-WUS by increasing the power, repeating transmission, and the like.

[0231] Generally, the network will provide the terminal with configuration parameters of the LP-WUS through RRC signaling, such as the frequency domain resource and bandwidth of the LP-WUS signal, the time domain period and symbol length, and the like. The UE can determine the resource blocks and time domain positions in which the LP-WUS can be detected according to these configuration parameters, that is, determine the detection opportunity of the LP-WUS. On the other hand, if the UE only determines to detect the LP-WUS according to the RRC configuration of the network and determines whether to detect the PDCCH according to the detection result of the LP-WUS, there can be some problems. For example, when the user equipment with poor reception performance of the LP-WUS moves out of the coverage area of the LP-WUS but is still in the coverage area of the PDCCH, the UE can continue to detect the related wake-up information according to the previously configured LP-WUS to enable the detection of the PDCCH. In fact, at this time, the UE outside the coverage area of the LP-WUS cannot correctly receive the LP-WUS signal, and therefore cannot trigger the detection of the related PDCCH, resulting in interruption of the service. An improved solution is for the UE to determine whether to detect the LP-WUS only according to the semi-static LP-WUS configuration or also according to the dynamic indication in the MAC-CE or DCI according to the indication of the network. The UE can report the related capabilities of the UE and the measurement report, and the base station can instruct the related behavior of the UE according to the downlink signal coverage in the network, the capabilities of the UE, and the measurement results reported by the UE.

[0232] According to another aspect of the disclosure, the UE can determine whether to detect the LP-WUS according to the related information, and determine to detect the PDCCH according to the indication in the LP-WUS. Specifically, the UE detects the LP-WUS according to the second indication, i.e. when the UE receives the second indication, the UE detects the LP-WUS on the detection opportunity of the LP-WUS determined by the high layer parameter. If the UE detects the LP-WUS according to the second indication and the third indication, the UE further determines whether to detect the LP-WUS on the LP-WUS detection opportunity in the time domain range according to the third indication.

[0233] For example, the second indication is RRC signaling, and the second indication can include a valid period length parameter of the UE detecting the LP-WUS in the time domain, a detection mode used by the UE, etc. The third indication is MAC-CE or DCI signaling, and is used to indicate whether the UE detects the LP-WUS in the time domain range determined according to the related configuration when the UE determines to detect the LP-WUS using the third indication.

[0234] The base station can indicate the related action of the UE by one of the following indication combinations:

[0235] • The base station configures the second indication for the UE, and the valid period length parameter of the LP-WUS is infinity, and the UE determines to detect the LP-WUS according to the second indication;

[0236] • The base station configures the second indication for the UE, and the valid period length parameter of the LP-WUS is not infinity, and the UE determines to detect the LP-WUS according to the second and third indications.

[0237] For a specific example, the network configures the frequency domain position, bandwidth parameter, period, time slot offset, number of symbols, and position of the associated bit information of the UE in the LP-WUS for the UE by RRC signaling; the UE can determine a plurality of LMOs according to these parameters. If the valid period length parameter in the second indication is infinity, the UE determines to detect the LP-WUS according to the second indication, i.e. during the valid period of the RRC signaling, i.e. during the configuration period which is not reconfigured or deleted, the UE always detects the LP-WUS on the related LMO.

[0238] On the other hand, the UE determines to detect the LP-WUS according to the second and third indications includes that if the valid period length parameter in the second indication is not infinity, e.g. a time of a plurality of milliseconds, a number of DRX cycles, or a number of time slots, etc., the UE further determines whether to detect the LP-WUS on the LP-WUS detection opportunity in the time domain range related to the related valid period according to the third indication.

[0239] Optionally, the UE determines whether to perform the LP-WUS detection on the LP-WUS detection occasion in the relevant time domain range in the relevant on-duration according to the third indication, including determining to perform the LP-WUS detection on the LP-WUS detection occasion in the on-duration in which the third indication is received and / or the next on-duration.

[0240] Optionally, the UE determines to perform the LP-WUS detection on the LP-WUS detection occasion in the next on-duration according to the third indication. For example, the network sends the LP-WUS enabling command through the MAC-CE. After receiving the command, the UE performs the detection on each LP-WUS detection occasion in the next on-duration of the on-duration in which the command is received, and determines whether to perform the PDCCH detection according to the received WUS information. Similarly, the network sends the LP-WUS disabling command through the MAC-CE. After receiving the command, the UE does not perform the LP-WUS detection in the next on-duration, and does not need to determine whether to perform the PDCCH detection according to the indication of the WUS (for example, the PDCCH detection can be directly performed according to the configuration of the PDCCH).

[0241] Another example, the network indicates whether the UE performs the detection on each WUS detection occasion in the next on-duration of the on-duration in which the DCI is received through part of the bit field in the DCI as the third indication. For example, bit 1 in the bit field in the DCI indicates that the UE performs the detection on each WUS detection occasion in the next on-duration, and determines whether to perform the PDCCH detection according to the detection of the WUS; bit 0 indicates that the UE does not perform the detection on the WUS in the next on-duration, and the UE does not need to determine whether to perform the PDCCH detection according to the indication of the WUS.

[0242] Optionally, the UE can determine to perform the LP-WUS detection from the current time slot or the next time slot of the current time slot to the end of the next on-duration according to the third indication. The current time slot is the time slot in which the UE receives the PDCCH of the DCI of the third indication or the PDCCH used to schedule the PDSCH (MAC-CE) carrying the third information. For example, the network sends the LP-WUS enabling command through the MAC-CE. After receiving the command, the UE performs the detection on each WUS detection occasion from the current time slot to the next on-duration, and determines whether to perform the PDCCH detection according to the detection of the WUS. Similarly, the network sends the WUS disabling command through the MAC-CE. After receiving the command, the UE does not perform the detection on the WUS from the current time slot to the next on-duration, and does not need to perform the PDCCH detection according to the indication of the WUS (for example, the PDCCH detection can be directly performed according to the configuration of the PDCCH).

[0243] Here, one validity period can contain several time slots or several DRX cycles, so the UE can receive multiple third indication information in the same validity period, and the UE does not expect these third indication information to indicate different LP-WUS detection indication information.

[0244] Optionally, the enabling command for indicating LP-WUS detection in the third indication information can also use one or more bit information. For example, one enabling command contains 2 bits, using the first bit to indicate whether the UE detects LP-WUS in the next validity period, and using the second bit to indicate whether the UE detects LP-WUS in the current validity period.

[0245] Optionally, when the UE determines the detection of LP-WUS according to the second and third information, if the UE does not receive any third indication information in one validity period, the UE determines not to detect LP-WUS in the next adjacent validity period, and does not need to determine whether to perform PDCCH detection according to the indication of WUS (for example, can directly perform PDCCH detection according to the configuration of PDCCH).
