Description

Methods executed by user equipment and user equipment Technical Field

[0001] This invention relates to the field of wireless communication technology, and more specifically to a method for determining downlink frequency domain resources performed by a user equipment, and the corresponding user equipment. Background Technology

[0002] This section provides information that can help to better understand the various aspects of the invention. Therefore, the statements in this section should be read in this light and should not be construed as an admission of what is prior art or what is not prior art.

[0003] 5G systems can be used in mobile phones and various vertical applications. Besides latency, reliability, and availability, energy efficiency of user equipment is also a key factor for 5G. In current systems, 5G devices typically consume tens of milliwatts in idle or inactive states and hundreds of milliwatts in connected states. Depending on the application scenario, 5G devices may require charging weekly or daily, causing inconvenience in practical applications. Therefore, designs that further extend battery life are necessary to improve energy efficiency and enhance the user experience. For devices using micro-batteries or those where charging is inconvenient, such as sensors, automatic controllers, and wearable devices, standby time may be 1-2 weeks or longer, making improved energy efficiency even more critical.

[0004] User equipment (UE) can typically save power using discontinuous reception (DRX or eDRX), with power consumption depending on the configured cycle, such as the paging cycle length. To meet battery life requirements, DRX or eDRX cycles with very large cycle values ​​can be applied, but this results in high latency, making it unsuitable for some scenarios. One such scenario is applications requiring both long battery life and low latency, such as fire detection and extinguishing devices with response times of only 1-2 seconds. Therefore, there is a need to research ultra-low-power mechanisms with low latency, such as latency lower than that introduced by eDRX in existing technologies.

[0005] In the current system, to maintain the connection between user equipment (UE) and the network, UE needs to periodically wake up in each DRX cycle to detect the control channel. Even when there is no data transmission for UE, UE still incurs periodic power consumption. If UE could wake up only when there is service demand, such as only when paging, its power consumption would be significantly reduced. Therefore, an ultra-low-power receiver can be designed for UE to detect the wake-up signal (WUS) sent by the base station. The UE's main transceiver can remain in sleep mode until the ultra-low-power receiver receives the WUS and wakes up the main transceiver for corresponding data processing. This allows for the correct operation of UE services with minimal power consumption. To achieve this design goal, several issues need to be addressed, such as on which of the several WUS detection opportunities configured by the base station the UE should perform WUS detection, and under what conditions the UE can detect WUS, etc. Summary of the Invention

[0006] To address at least some of the above-mentioned problems, the present invention provides a method performed by a user equipment and a user equipment thereof.

[0007] According to a first aspect of the present invention, a method performed by a user equipment (UE) in an idle RRC_IDLE state or an inactive RRC_INACTIVE state is disclosed, comprising: the UE receiving configuration parameters of low-power wake-up signal (LP-WUS) resources from a base station; the UE determining a plurality of LP-WUS detection opportunities (LP-WUS MOs) for detecting LP-WUS, and a reference signal associated with the LP-WUS MOs, based on at least one of a frequency division multiplexing coefficient, a time-domain repetition coefficient, and a transmission configuration indication (TCI) parameter in the configuration parameters of the LP-WUS resources.

[0008] Preferably, the UE determines multiple LP-WUS detection opportunities (LP-WUS MOs) for LP-WUS detection by determining K consecutive LP-WUS MOs using the same TCI parameters as LP-WUS MOs for LP-WUS detection by the UE, where K is the number of LP-WUS MOs for each beam determined by the UE based on the frequency division multiplexing coefficient and / or the time-domain repetition coefficient.

[0009] Preferably, the step of the UE determining K consecutive LP-WUS MOs using the same TCI parameters as LP-WUS MOs for LP-WUS detection further includes:

[0010] The K consecutive LP-WUS MOs satisfy the following condition:

[0011] - If the cell is configured with uplink / downlink symbols and time slot parameters tdd-UL-DL-ConfigurationCommon, the LP-WUS MO does not overlap with the uplink symbols determined by these parameters;

[0012] -LP-WUS MO does not overlap with the PRB of the SSB actually transmitted in the cell;

[0013] - The LP-WUS MO frequency division multiplexing with LP-WUS MO does not overlap with the PRB of the SSB actually transmitted in the cell.

[0014] Furthermore, according to a second aspect of the present invention, a user equipment is provided, comprising: a processor; and a memory storing instructions, wherein the instructions, when executed by the processor, perform the methods described above.

[0074] The following is a description of technologies associated with the present invention. Unless otherwise specified, the same terms in the specific embodiments and the associated technologies have the same meanings.

[0075] It is worth noting that the terms "user," "user equipment," and "terminal" used in this specification have the same meaning. The term "UE" can also be used to refer to a user equipment in this document, and no specific distinction or limitation will be made thereafter. Similarly, "network equipment" refers to equipment that communicates with user equipment, including but not limited to base station equipment, gNB, eNB, wireless AP, wireless relay, and user equipment with relay capabilities, etc., and no specific distinction or limitation will be made thereafter. The document may use a base station as one form of network equipment implementation, but other forms of network equipment can be easily used in actual implementation.

[0076] In NR networks, base stations can configure the `tdd-UL-DL-ConfigurationCommon` parameter in the System Instruction Broadcast (SIB) to indicate the uplink and downlink status of OFDM symbols on TDD carriers. For example, this parameter can indicate whether all symbols in some time slots are uplink, all are downlink, some are uplink, or some are downlink. The UE can determine whether a symbol in a time slot is an uplink symbol, a downlink symbol, or unspecified (i.e., a flexible symbol) based on this parameter. Depending on the network configuration or scheduling information, the UE can transmit uplink signals on uplink symbols and receive downlink signals on downlink symbols. The UE may also further determine the uplink and downlink status on flexible symbols based on other RRC signaling, or choose not to use these symbols for related signal reception or transmission.

[0077] The NR network can indicate the parameters for SSB transmission via SIB or RRC messages. For example, the network uses the `ssb-PositionsInBurst` parameter in SIB1 to indicate the sequence number of the actually transmitted SSB. `ssb-PositionsInBurst` can further include multiple sub-parameters. For instance, the network uses the `inOneGroup` parameter (group identifier parameter) to indicate the transmission status of all SSBs or individual SSBs within each SSB group. When the maximum number of SSBs in each half-frame is 4, 4 valid bits are used to represent the transmission status of each SSB. When the maximum number of SSBs in each half-frame is 8, 8 bits are used to represent the transmission status of the SSBs. The leftmost bit of the `inOneGroup` parameter corresponds to the SSB sequence number 0. When the maximum number of SSBs in a half-frame is 64, every 8 SSBs can be grouped, and 8 bits are used to represent the transmission status of the SSBs in each group. The leftmost bit of `inOneGroup` corresponds to the sequence number of the first SSB in each group, i.e., SSB sequence numbers 0, 8, 16, etc., and so on for the other bits. In `inOneGroup`, setting any bit to 0 indicates that the corresponding SSB is not actually transmitted, while setting any bit to 1 indicates that the SSB corresponding to the relevant sequence number is transmitted. When the maximum number of SSBs in a half-frame is greater than 8, such as 64, the network also uses an 8-bit `groupPresence` parameter to indicate the presence of each antenna group. The leftmost bit of `groupPresence` is related to SSB numbers 0-7, the second bit is related to SSB numbers 8-15, and so on. Using a bit set to 0 indicates that the SSBs in that group do not exist, or that none of the SSBs in that group are transmitted. Setting any bit in `groupPresence` to 1 indicates that the SSBs in that group are transmitted or not transmitted according to the indication in `inOneGroup`. In this way, the network can indicate the sequence numbers of all actually transmitted SSBs in a half-frame under various scenarios. SSBs transmitted by the base station can be transmitted using different beams (also called spatial filters) to achieve better cell coverage. SSBs with different beams can be represented by different SSB sequence numbers, and other signals using SSBs as reference signals can obtain relevant beam information based on the SSB sequence number.

[0078] In NR networks, even when there is no data transmission, the UE maintains a data connection with the network to provide always-on network services. For example, a UE in idle state (RRC_IDLE state) or inactive state (RRC_INACTIVE state) periodically checks whether the base station has sent it a paging message.

[0079] To receive paging information from the network, the UE determines the paging cycle (DRX cycle for paging) and the location of the paging occasion (PO) within each paging cycle based on the parameters configured by the base station. It then detects the paging PDCCH on the PDCCH monitoring occasion for paging (MO) associated with the PO and performs the next action based on the content indicated in the paging PDCCH. According to relevant protocols in NR (e.g., 38.304v17.0.0), an idle or inactive UE can detect one PO in each DRX cycle. The UE can determine several POs in the time domain based on the parameters configured by the base station. The UE can also determine the paging cycle T for receiving paging messages based on the base station's configuration parameters, where T radio frames constitute one paging cycle. The UE can also determine the number N of paging frames (PF) in a paging cycle based on the base station configuration. A paging frame is a radio frame and can contain one or more POs or the start of a PO. In this invention, a PF may be associated with or contain one or more POs, or simply referred to as the PF of a PO, the PO as the PO of a PF, etc.

[0080] A Point of Interest (PO) can be a set of several Moving Averages (MOs). For example, in a network using multi-beam transmission, different MOs in the PO can correspond to different downlink beams, allowing UEs using different beams to achieve good PO detection performance. The UE can select MOs in the PO to receive the PDCCH based on its own circumstances. For example, the UE can select one or more MOs to detect the paging PDCCH based on SSB measurement information. If the UE correctly detects the paging PDCCH, it will perform paging PDSCH reception or other related actions based on the relevant information in the DCI on the detected PDCCH.

[0081] For example, in a paging cycle of T radio frames, there are N paging frames. The UE determines one paging frame in this paging cycle as the paging frame for which the UE needs to detect paging information. When a paging frame PF is associated with multiple POs, the UE determines one of them as its PO, and the UE detects the paging PDCCH on that PO. The UE can obtain the frame number SFN of the PF corresponding to the PO that the user needs to detect based on parameters such as the UE_ID. The SFN is determined to satisfy the following conditions:

[0082] (SFN+PF_offset)mod T=(T / N)*(UE_ID mod N)

[0083] Where PF_offset is the paging frame offset value configured by the base station, T is the paging cycle period determined by the UE, N is the number of paging frames in one paging cycle, mod is the modulo operation, and UE_ID is the UE ID value used to determine the paging parameters, determined according to the relevant protocol in NR (e.g., 38.304v17.0.0).

[0084] The UE determines the frame number of the paging frame (PF) and then determines the PO to be detected. Depending on the base station configuration, one PF may be associated with Ns POs. The UE needs to determine which PO to detect in order to check the relevant PDCCH and determine if there is a corresponding paging message, etc. This PO can also be called the UE's PO. For example, the UE can determine the PO to be detected based on the PO sequence number i_s of the PF:

[0085] i_S = floor(UE_ID / N) mod Ns,

[0086] Where Ns is the number of POs configured in one PF of the base station. floor is the floor operation.

[0087] After determining the PO, the UE can determine the information of each detection opportunity MO based on the paging search space set parameters configured by the base station. For example, the UE can determine the PO sequence number and the S*X consecutive MOs associated with the PO starting from the PF radio frame. Here, S is the number of SSBs actually transmitted in one SSB cycle in the network, which can be determined, for example, by the ssb-PositionsInBurst parameter in SIB1. The X value defaults to 1, but can also be configured by higher layers. Each S MO of the PO is associated with S different SSB sequence numbers, or in other words, they satisfy the QCL relationship according to the SSB numbering order. Optionally, if the base station configures the time slot and / or symbol offset parameters for the first MO in the PO, the UE also determines the specific location of each MO from the offset after the PF radio frame.

[0088] The UE can detect the paging PDCCH using the method described above on the relevant time-frequency resources. The DCI in the paging PDCCH contains information such as whether the user needs to receive a corresponding paging message, whether there is a specific short message, etc. If a paging message is to be received, the DCI also indicates the PDSCH resource parameters used to transmit the paging message, including time-domain resources, frequency-domain resources, modulation scheme, etc. The UE can receive the paging PDSCH based on these parameters.

[0089] To maintain network connectivity, UEs typically periodically check for paging messages, even if a sent paging message is unrelated to the UE. This behavior consumes significant UE power, impacting battery life and reducing user experience.

[0090] One feasible method is for the UE to use a low-power auxiliary receiver to detect the wake-up signal (WUS) sent by the base station. When there is no data transmission, the UE's main radio (MR) remains in sleep mode, and the UE uses a low-power wake-up receiver (LP-WUS, or LR for short) to detect the WUS to reduce power consumption. When data needs to be transmitted, the base station notifies the UE through the WUS. When the UE detects the indication carried in the WUS, it wakes up the MR and performs corresponding data processing, such as detecting the point of origin (PO). Since the WUS here is used for low-power receiver detection, it can also be called LP-WUS (low-power WUS). In this invention, LP-WUS can also be simply referred to as WUS, without further explanation.

[0091] The LP-WUS can contain relevant information needed to wake up the UE, and one LP-WUS can be used to indicate wake-up information for multiple users or user groups. For a specific UE or UE group, the LP-WUS can contain the UE's RNTI or RNTI-related information, or indication bits for the UE or UE group, or indication sequences for the UE or UE group, etc. The UE can determine whether it is to be woken up by the LP-WUS based on the relevant information in the LP-WUS. Only when the UE detects wake-up indication information for the UE or UE group will the UE wake up the master transceiver to perform relevant data transmissions, including detecting paging PDCCH on the UE's PO, or transmitting PRACH preamble, etc. In this way, the UE can maintain its connection with the network with minimal power consumption.

[0092] LP-WUS can use OOK (On-Off Keying) waveforms for transmission, reducing receiver complexity. For compatibility with existing NR equipment, OOK can be generated using methods compatible with OFDM symbols, such as multi-carrier OOK. In this case, an OFDM symbol length can contain an integer number of OOK symbols within the LP-WUS bandwidth, such as 1 / 2 / 4 / 8 / 16, making it easy for the base station to transmit signals with different waveforms. Therefore, the time-domain length of the resources used for LP-WUS transmission can also be described using parameters such as OFDM symbols and time slots.

[0093] The OOK symbol used by the base station to transmit LP-WUS occupies a certain amount of effective bandwidth. Furthermore, to facilitate UE receiver implementation, some guard bands are reserved outside the effective bandwidth and not used for signal transmission; these can be called guard bands. In this invention, unless otherwise specified, the frequency domain bandwidth used for transmitting resources used in LP-WUS includes the bandwidth actually used for transmitting the OOK symbol and the guard band. To ensure compatibility with existing NR equipment, the OOK can be generated using a method compatible with OFDM symbols, and the bandwidth of the frequency domain resources used for transmitting LP-WUS can also be described using the number of resource blocks (RBs).

[0094] The base station can also transmit a lower power synchronization signal (LP-SS) for the UE to perform related synchronization parameter estimation, RRM measurement, or as a reference signal for LP-WUS spatial transmission. LP-SS can use similar waveforms and modulation schemes to LP-WUS. LP-SS may use a multi-beam transmission method similar to SSB. The number of beams used for LP-SS transmission can be the same as the number of beams used for SSB. The number of beams used for LP-SS transmission may also be determined by LP-SS related configuration parameters; for example, the UE can determine the number of beams for LP-SS transmission based on the number of LP-SS resources in the LP-SS resource set.

[0095] Base stations can configure resources for transmitting LP-WUS by providing LP-WUS resource or resource set parameters in System Broadcast Information (SIB). These parameters include symbol positions, RB positions, etc., used for LP-WUS transmission. These resources repeat periodically in the time domain, and the base station can transmit LP-WUS on these resources according to the UE's data transmission requirements. A UE can detect LP-WUS on some of these resources; these opportunities to detect LP-WUS are called LP-WUS monitoring occasions (LMOs). Therefore, a resource used for transmitting LP-WUS can be called an LP-WUS resource from the base station's perspective and an LP-WUS MO from the UE's perspective.

[0096] Idle or inactive UEs can use DRX to detect LP-WUS. For example, the UE determines several wake-up opportunities (LP-WUS occasions, LOs) according to a certain period. An LO can be a set of several LP-WUS MOs, or an LO can contain or be associated with several LP-WUS MOs. The UE determines the LO and performs LP-WUS detection on the LP-WUS MOs of the LO. The LP-WUS on these LP-WUS MOs may be transmitted using multiple beams (also called spatial filters) to cover UEs using different beams. When using multiple beams, the UE assumes that the same LP-WUS is transmitted on all different beams associated with LP-WUS (on the LO). The LP-WUS MOs of the LO are also used to indicate different user packets or to repeatedly transmit LP-WUS to enhance downlink reception performance, etc.

[0097] Spatial transmission or beam information for LP-WUS can be indicated using Transmission Control Indication (TCI) parameters. The TCI parameters may include information related to LP-WUS-related reference signals, such as the ID or sequence number of the LP-WUS-related reference signal contained in the TCI parameters, QCL type, etc. The LP-WUS resource / LP-WUS MO using this TCI parameter applies the same QCL parameters as the reference signal with that ID or sequence number. The UE can detect LP-WUS using frequency offset and time offset parameters, beam spatial characteristics, etc., estimated from this reference signal. In NR, the reference signal for LP-WUS may be an SSB or LP-SS. For example, when the UE determines that the beam used by a certain LP-WUS MO is the same as the SSB of sequence number x, the UE can use the same beam parameters as that SSB to detect LP-WUS on the corresponding LP-WUS MO. For simplicity, this invention may use descriptions such as LP-WUS MO using a certain beam or UE using a certain beam to detect LP-WUS MO to illustrate the relevant processes.

[0098] Several issues need to be addressed when applying LP-WUS to reduce UE power consumption in a network. These include how the UE determines the LP-WUS MO in the LO based on LP-WUS resources or resource set parameters, the beam used by the LP-WUS MO, and in what scenarios LP-WUS needs to be detected on the LO. This invention provides a method to solve these problems, enabling the UE to achieve better power savings through cooperation between the base station and the UE.

[0099] The following examples are provided to describe the implementation of the present invention in more detail.

[0100] In one embodiment of the present invention, the UE receives LP-WUS resource configuration parameters configured by system broadcast information, and the UE determines the LP-WUS MO used for LP-WUS detection, as well as the reference signal, beam parameters, etc. used therein.

[0101] Figure 1 is a flowchart of a method executed by a UE according to an embodiment of the present invention.

[0102] As shown in Figure 1, in step S101, the UE receives the LP-WUS resource or resource set configuration in the system broadcast information. In step S103, the UE determines the LP-WUS MO according to the LP-WUS resource configuration. In step S105, the UE determines the LP-WUS MO used for LP-WUS detection and the reference signal related to the LP-WUS MO.

[0103] The relevant process is described in detail below.

[0104] In one embodiment of the present invention, the base station can configure resources for transmitting LP-WUS through LP-WUS resources or resource set parameters in the system broadcast information. The UE can obtain the time-frequency resource parameters used by the base station when transmitting LP-WUS based on these parameters, including the repetition period, the time slot and symbol offset relative to the start of the period, the number of consecutive symbols used, the starting RB position and the number of RBs, and whether frequency division multiplexing and / or time domain repetition are supported, etc.

[0105] In one example, the base station configures resources for LP-WUS transmission via the LP-WUS-resource parameter. A specific example of the LP-WUS-resource structure is shown below:

[0106] In this parameter configuration example, the LP-WUS-resource parameter can contain several sub-parameters. For ease of explanation, each sub-parameter is divided into two items: the first is the sub-parameter name, and the second is the sub-parameter type and value. The type may be an integer INTEGER, an enumeration ENUMERATED, a multiple-choice CHOICE, a sequence SEQUENCE, etc. In this example, powerControlOffsetSS is used to configure the transmit power of LP-WUS, representing the difference (offset) between the LP-WUS power and the LP-SS power when the base station transmits LP-SS and LP-WUS with OOK symbol 1. firstOFDMSymbolInTimeDomain is the starting symbol sequence number on the first time slot occupied by the LP-WUS resource. symbolsDuration is the number of consecutive OFDM symbols occupied by the LP-WUS resource. `startingRB` represents the starting RB number for LP-WUS resources, counting from CRB#0 (Common resource block number 0). For example, when the base station configures a specific point A parameter for LP-WUS, CRB#0 starts from the subcarrier where point A is located; otherwise, it starts from CRB#0 used by the initial downlink BWP of the cell where the UE is located. `nrofRBs` is the number of RBs occupied by one LP-WUS resource. `fdmNumberAndGuardband` is used for parameters related to frequency division multiplexing (FDM) of LP-WUS MOs, such as the LP-WUS MO frequency division multiplexing coefficient `nrofLP-WUS-MOFDMedInPO`, and the size of the guard sideband between LP-WUS MOs in FDM, etc. `repFactorAndTimeGap` is used to configure the repetition coefficient `nrofLP-WUS-MORepeatedInPO` when the network supports time-domain repetition of LP-WUS MOs, and the interval `repetitionTimeGap` between two consecutively repeating LP-WUS MOs, etc. The periodicity-and-SlotOffset is used to configure the periodicity of LP-WUS resources and the starting slot position within the period.

[0107] This document lists only some parameters used to illustrate the examples of this invention. Actual network cells may contain several unlisted sub-parameters. Furthermore, the names and structures of the parameters and sub-parameters mentioned above are exemplary; the value ranges for these parameters in actual networks may differ from those in the examples. For instance, the LP-WUS resource parameter LP-WUS-resource may use the name of the LP-WUS monitoring parameter LP-WUS-monitoring, etc. Additionally, the base station may not configure some of these parameters; in this case, the UE may use default values ​​or not apply the relevant features. These parameters may also be configured by the base station to the UE through multiple parameter groups. For example, parameter group 1 includes powerControlOffsetSS, firstOFDMSymbolInTimeDomain, symbolsDuration, startingRB, nrofRBs, etc., and parameter group 2 includes fdmNumberAndGuardband, repFactorAndTimeGap, periodicity-and-SlotOffset, etc. These different configuration forms do not affect the UE's determination of the relevant resources for LP-WUS transmission or the determination of the LP-WUS MO used for LP-WUS detection.

[0108] Based on the LP-WUS resource parameters configured by the base station, the UE can determine several resource blocks and LP-WUS MOs that may be used for LP-WUS transmission. A specific example is shown in Figure 2, in which the frequency division multiplexing coefficient of nrofLP-WUS-MOFDMedInPO is configured as 2, and the UE can determine several LP-WUS MOs based on these parameters.

[0109] Idle or inactive UEs can use DRX (Discontinuous Reception) to detect LP-WUS. The UE determines the location of the opportunity location (LO) for LP-WUS based on higher-layer configuration parameters (such as the detection period), for example, by determining the LO's location based on the offset between the LO and the associated UE's PO. An LO is a set of several LP-WUS MOs. The UE can perform LP-WUS detection only on the LP-WUS MOs within a determined LO. For example, the UE determines that an LO contains N*K LP-WUS MOs, where N is the number of LP-WUS-related beams determined by the UE, and K is the number of LP-WUS MOs in each beam determined by the UE. When there are no relevant TCI parameters (such as reference signal ID) in the LP-WUS resource configuration parameters, the UE can determine the reference signal and beam information of the LP-WUS MOs in the LO according to certain rules. This allows the UE to select the LP-WUS MO using that beam for detection based on measured spatial transmission conditions or the optimal beam, achieving better detection performance and power saving.

[0110] Optionally, LP-WUS uses SSB as a reference signal, and the UE determines N as the actual number of SSBs transmitted based on the ssb-PositionsInBurst parameter.

[0111] Optionally, LP-WUS uses LP-SS as a reference signal, and the UE determines N as the different spatial transmission parameters or number of beams used when transmitting LP-SS.

[0112] Optionally, the UE determines K*N sequentially conditional LP-WUS MOs based on at least one of the FDM coefficients nrofLP-WUS-MOFDMedInPO and the repetition coefficient nrofLP-WUS-MORepeatedInPO; and the UE determines that among these K*N LP-WUS MOs, the Xth LP-WUS MO is related to the reference signal of the nth LP-WUS. Here, n is the sequence number of the reference signal used by the base station to transmit the LP-WUS; when the LP-WUS uses an SSB as the reference signal, that is, when the signal transmitting a certain LP-WUS always satisfies the QCL with a certain SSB, the reference signal of the nth LP-WUS is the nth actually transmitted SSB, corresponding to the sequence number n of the actually transmitted SSB; when the LP-WUS uses an LP-SS as the reference signal, the reference signal of the nth LP-WUS is the nth LP-SS, corresponding to the sequence number n of the actually transmitted LP-SS.

[0113] Optionally, the LP-WUS MO numbers can be determined sequentially using a frequency domain priority approach. That is, when frequency division multiplexing factors are configured, starting with the first LMO that meets the conditions and uses the lowest bandwidth, the LMOs are determined one by one in the order of frequency domain first, then time domain.

[0114] Optionally, when the base station is also configured with offset parameters between LP-WUS MO and LO, the UE sequentially selects K*N LP-WUS MOs that meet the conditions, starting from the LP-WUS MOs that satisfy the offset parameter requirements. The offset can be the number of time slots or symbols, or the number of LP-WUS MOs.

[0115] Optionally, a satisfying LP-WUS MO is one or more of the following conditions:

[0116] - If the cell is configured with the uplink / downlink parameter tdd-UL-DL-ConfigurationCommon, the LP-WUS MO does not overlap with the uplink symbol determined by this parameter.

[0117] -LP-WUS MO does not overlap with the PRB of the SSB actually transmitted in the cell.

[0118] - The LP-WUS MO of the frequency division multiplexing FDM does not overlap with the PRB of the SSB actually transmitted in the cell.

[0119] Optionally, the UE determines the value of sequence number X according to one of the following methods:

[0120] -X = K2*n + k2, where K2 is the number of MOs corresponding to each beam in the LO. For example, when the base station is configured with nrofLP-WUS-MOFDMedInPO, K2 is the value configured for nrofLP-WUS-MOFDMedInPO; k2 = 0, ..., K2-1. In this case, K = K2.

[0121] -X = K1*n + k1, where K is the number of MOs corresponding to each beam in the LO. For example, when the base station is configured with nrofLP-WUS-MORepeatedInPO, K1 is the value configured for nrofLP-WUS-MORepeatedInPO; k1 = 0, ..., K1-1. In this case, K = K1.

[0122] -X = k1*N*K2 + K2*n + k2, where k1 = 0, ..., K1-1; k2 = 0, ..., K2-1; For example, when the network is configured with both nrofLP-WUS-MORepeatedInPO and nrofLP-WUS-MOFDMedInPO, K1 is the value configured for nrofLP-WUS-MORepeatedInPO, and K2 is the value configured for nrofLP-WUS-MOFDMedInPO. In this case, K = K1*K2.

[0123] -X = k2*N*K2 + K1*n + k1, where k1 = 0, ..., K1-1; k2 = 0, ..., K2-1. For example, when the network is configured with both nrofLP-WUS-MORepeatedInPO and nrofLP-WUS-MOFDMedInPO, K1 is the value configured for nrofLP-WUS-MORepeatedInPO, and K2 is the value configured for nrofLP-WUS-MOFDMedInPO. In this case, K = K1*K2.

[0124] A specific example is shown in Figure 3. In this example, the UE determines consecutive LP-WUS MOs from the reference point of the LO, which do not overlap with uplink symbols, among several LP-WUS MOs determined according to LP-WUS resources or resource sets. In the example, the 0th, 1st, 8th, and 9th LP-WUS MOs are related to the reference signal of the 0th LP-WUS (e.g., SSB 0), the 2nd, 3rd, 10th, and 11th LP-WUS MOs are related to the reference signal of the 1st LP-WUS (e.g., SSB 1), the 4th, 5th, 12th, and 13th LP-WUS MOs are related to the reference signal of the 2nd LP-WUS (e.g., SSB 2), and the 6th, 7th, 14th, and 15th LP-WUS MOs are related to the reference signal of the 3rd LP-WUS (e.g., SSB 3).

[0125] In another example of the present invention, the base station can configure LP-WUS related parameters through LP-WUS resources and resource set parameters in the system broadcast information. The UE can determine the time-frequency resources used by the network to transmit LP-WUS based on these parameters, including the repetition period and the time slot and symbol offset relative to the period reference point, the number of consecutive symbols used by the resources, the starting RB position and the number of RBs, whether frequency division multiplexing and / or time domain repetition are supported, the TCI or reference signal used by LP-WUS, etc.

[0126] In this example, the base station configures parameters for several LP-WUS resources through the LP-WUS-resourceSet parameter in the SIB. A specific example of the LP-WUS-resourceSet structure is shown below:

[0127] In this example, an LP-WUS resource set is configured using LP-WUS-resourceSet. This set contains several groups of LP-WUS-resource parameters associated with LP-WUS-resourceIDs, indicating that the resource set contains related LP-WUS resources. Parameters shared by LP-WUS resources within the LP-WUS resource set can be configured via the LP-WUS-ResourceSetComm parameter to reduce signaling overhead. In this example, for each LP-WUS-Resource, a TCI parameter (here, referenceSignal) can be configured to instruct the LP-WUS MO determined based on this resource parameter to use the beam of the SSB (using the parameter ssb to indicate the corresponding SSB number) or LP-SS indicated in the relevant referenceSignal (using the parameter lp-ss to indicate the corresponding LP-SS number). Parameters identical to those in other examples of this invention will not be described individually. Furthermore, only some parameters used to illustrate this example are listed here; actual network cells may contain several unlisted sub-parameters. Furthermore, the names and structures of the parameters and sub-parameters mentioned above are exemplary; the value ranges of these parameters may differ from those in the examples when applied in actual networks. These different configuration forms do not affect the UE's determination of the relevant resources for LP-WUS transmission or the determination of the LP-WUS MO used for LP-WUS detection.

[0128] A specific example is shown in Figure 4. In this example, an LP-WUS resource set contains four LP-WUS resources, corresponding to LP-WUS resources with resourceIDs of 0, 1, 2, and 3, respectively, and these resources are applied to beams with sequence numbers 0, 1, and 2 respectively (the illustration of the LP-WUS MOs determined based on resourceIDs 2 and 3 is omitted in the figure). In addition, the base station is also configured with FDM parameters, using frequency division multiplexing (FDM). Therefore, the UE can determine several LP-WUS MOs using relevant beams based on the parameters of this resource set.

[0129] UEs in idle or inactive states can use DRX (Discontinuous Reception) to detect LP-WUS. For example, the UE determines the opportunity location (LO) for LP-WUS based on a certain detection period. An LO is a set of several LP-WUS MOs. For instance, the UE determines that an LO contains N*K LP-WUS MOs, where N is the number of LP-WUS-related beams and K is the number of MOs per beam. The UE can perform LP-WUS detection only on the LP-WUS MOs within the determined LO.

[0130] Optionally, LP-WUS uses SSB as a reference signal, and the UE determines N as the actual number of SSBs transmitted based on the ssb-PositionsInBurst parameter.

[0131] Optionally, LP-WUS uses LP-SS as a reference signal, and the UE determines N as the number of LP-SS transmitted using different spatial transmission parameters or beams.

[0132] Optionally, the UE determines the LP-WUS MO in the LO based on the number of beams N used for LP-WUS and the number of MOs K for each beam. The UE determines K consecutive LP-WUS MOs for each beam as LP-WUS MOs for LP-WUS detection.

[0133] Optionally, the UE determines K consecutive LP-WUS MOs for each beam, and also satisfies one or more of the following conditions:

[0134] - If the cell is configured with the uplink / downlink parameter tdd-UL-DL-ConfigurationCommon, the selected LP-WUS MO does not overlap with the uplink symbol determined by this parameter.

[0135] -LP-WUS MO does not overlap with the PRB of the SSB actually transmitted in the cell.

[0136] - The LP-WUS MO of the frequency division multiplexing FDM does not overlap with the PRB of the SSB actually transmitted in the cell.

[0137] Optionally, the UE determines the first LP-WUS MO of the UE's LO according to one of the following methods.

[0138] The first LP-WUS MO after the reference point of -LO

[0139] - When the base station configures the offset between the LP-WUS MO and the LO reference point, the UE determines the Xth LP-WUS MO in the LO by sequentially selecting the beam numbers of the LP-WUS MOs that meet the offset requirement and do not overlap with the uplink symbols.

[0140] The MO is related to the nth LP-WUS beam. The offset can be the number of time slots or symbols, or the number of LP-WUS MOs.

[0141] -The first LP after the previous LO in the time domain -WUS MO

[0142] The first LP-WUS MO using a specific reference signal number after the reference point of -LO.

[0143] This specific reference signal number can be a specific reference signal number configured by the base station. If the network does not configure this specific reference signal number, the UE can use a default reference signal number, such as the number of the smallest actually transmitted SSB.

[0144] The UE determines multiple LP-WUS detection opportunities (LP-WUS MOs) for LP-WUS detection, including identifying K consecutive LP-WUS MOs using the same TCI parameters (e.g., the same beam number, reference signal number, or ID, etc.) as LP-WUS MOs for LP-WUS detection, where K is the number of LP-WUS MOs for each beam determined by the UE based on the frequency division multiplexing coefficient and / or time-domain repetition coefficient.

[0145] For example, when the base station is configured with nrofLP-WUS-MOFDMedInPO, K2 is the value configured for nrofLP-WUS-MOFDMedInPO; in this case, K = K2.

[0146] For example, when the base station is configured with nrofLP-WUS-MORepeatedInPO, K1 is the value configured for nrofLP-WUS-MORepeatedInPO; in this case, K = K1.

[0147] For example, if both nrofLP-WUS-MORepeatedInPO and nrofLP-WUS-MOFDMedInPO are configured in the network, K1 is the value configured for nrofLP-WUS-MORepeatedInPO; K2 is the value configured for nrofLP-WUS-MOFDMedInPO. In this case, K = K1 * K2.

[0148] The UE can determine K LP-WUS MOs for N relevant TCI parameters, thus obtaining K*N LP-WUS MOs for LP-WUS detection.

[0149] A specific example is shown in Figure 5. The figure shows the LP-WUS MOs determined according to resourceIDs 0, 1, 2, and 3. These LP-WUS MOs use SSB 0, 1, 2, and 3 as reference signals, corresponding to beams 0, 1, 2, and 3, respectively.

[0150] In this example, N=4, K=2. The UE determines K LP-WUS MOs for each beam, starting from the first MO after the determined reference point offset. In this example, when determining LP-WUS MOs for beam 0, if an LP-WUS MO conflicts (overlaps) with an uplink symbol, the UE determines the next consecutive LP-WUS MO as the LP-WUS MO for that LO. Ultimately, the UE determines N*K LP-WUS MOs for each LO.

[0151] In another aspect of the present invention, the UE can also determine whether to perform LP-WUS detection in LP-WUS MO based on certain conditions. When the base station is configured with relevant LP-WUS parameters, the UE in idle or inactive state can determine whether to perform LP-WUS detection in LP-WUS MO based on different conditions.

[0152] The UE can use MR to measure related signals (e.g., SSB) to obtain downlink transmission signal quality (e.g., SS-RSRP). The UE may also use LP-WUR to measure the signal quality of LP-SS (e.g., LP-SS-RSPR). The UE can determine whether to perform LP-WUS detection based on the measurement and other conditions.

[0153] Optionally, the UE may detect LP-WUS if it determines, based on the indication in the RRC message, that the measurement using MR is higher than threshold 1 and / or the measurement of LP-WUS is higher than threshold 2. When the UE determines the comparison between the MR measurement and the LP-WUS measurement and the threshold based on the indication in the SIB or dedicated RRC message, it may do so under one of the following conditions:

[0154] - This indicates whether the base station has configured threshold 2 for LP-WUR measurements. If the base station has configured threshold 2 for LP-WUR measurements, the UE determines whether to detect LP-WUS by comparing the LP-WUR measurements with the threshold; otherwise, the UE determines whether to detect LP-WUS by comparing the LP-WUS measurements with the threshold.

[0155] - The indication is a conditional selection, for example, including indication value 1, indication value 2, and indication value 3. The UE determines the measurement of MR based on indication value 1, or determines the measurement of LP-WUR based on indication value 2, or simultaneously determines the measurement of MR and WUR based on indication value 3.

[0156] Optionally, the UE determines whether to detect LP-WUS based on LP-WUS resources and the frequency domain parameters of the initial downlink BWP, using MR measurements, LP-WUR measurements, or both MR and LP-WUR measurements compared with relevant thresholds, and the UE bases its decision on one of the following conditions:

[0157] The frequency domain location for determining the LP-WUS resource uses a different reference point (point A) than the one used by the serving cell or the initial downlink BWP. The UE determines this location based on the LP-WUR measurements.

[0158] The frequency domain location for determining the LP-WUS resource uses a different reference point A than the one used by the serving cell or the initial downlink BWP. The UE also uses measurements from both the LP-WUS and the MR.

[0159] The frequency domain location of the -LP-WUS resource is determined using the same point A reference point as the serving cell or the initial downlink BWP. The UE is only based on the MR measurement.

[0160] Optionally, an idle or inactive UE can initiate LP-WUS detection if the following conditions are met:

[0161] -MR measurements (e.g., RSRP measured according to SSB) are higher than entry threshold 1, if the base station provides entry threshold 1 via system broadcast information or dedicated RRC signaling, and

[0162] - The LP-WUR measurement (e.g., LP-RSRP measured according to LP-SS) is higher than the entry threshold 2, if the base station provides the entry threshold 1 via system broadcast information or dedicated RRC signaling, or

[0163] - The LP-WUR measurement (e.g., LP-RSRP measured according to LP-SS) is higher than the entry threshold 2, if the base station provides the entry threshold 1 via system broadcast information or dedicated RRC signaling, and the base station indicates the measurement according to LR in the conditions in the system broadcast message, or

[0164] The frequency domain location of the -LP-WUS resource is determined using a different reference point A than the one used by the serving cell or the initial downlink BWP.
