Abstract
Description
Low-power wake-up signal transmission method, device and equipment
[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This disclosure claims priority to Chinese patent application number 202410177856X, filed on February 8, 2024, entitled “Low-power wake-up signal transmission method, device and apparatus”, which is incorporated herein by reference in its entirety. Technical Field
[0003] The present disclosure relates to the field of communication technology, and in particular to a low-power wake-up signal transmission method, apparatus, and device. Background Art
[0004] The terminal energy-saving topic of Rel-18 proposes the concepts of low power wake-up signal (LP-WUS) and low power wake-up receiver (LP-WUR), which are applied on the basis of existing energy-saving technologies to further reduce the energy consumption of terminals. When the terminal is in the Radio Resource Control (RRC) idle (IDLE) / inactive (INACTIVE) mode, when the base station and the terminal have no business transmission, the main device (Main Radio, MR) with high energy consumption is turned off, so that the terminal can enter an ultra-deep sleep state, and at the same time, the LP-WUR device is turned on to receive the LP-WUS sent by the base station to determine whether it is necessary to wake up the MR to receive the paging information sent by the base station on the paging opportunity (Paging Occasion, PO). When the base station does not send paging information to the terminal, it can greatly save the terminal from receiving PO or paging early indication (Paging Early Indication, PEI) (for example, downlink control information (Downlink Control Information, DCI) 2_7) before the time-frequency synchronization preparation and monitoring the paging (Paging) physical downlink control channel (Physical downlink control channel, PDCCH) or DCI 2_7 signal. Unnecessary power consumption overhead.
[0005] In the LP-WUS topic of Rel-19, it is necessary to standardize the design and reception method of LP-WUS signals jointly generated by Amplitude-Shift Keying (ASK) / Frequency-Shift Keying (FSK) and Orthogonal Frequency Division Multiplex (OFDM). Considering that the information carrying capacity of LP-WUS signals is far inferior to PDCCH, LP-WUS cannot directly replace the existing energy-saving signaling based on Downlink Control Information (DCI) indication in RRC_IDLE / INACTIVE mode and RRC_CONNECTED mode. Therefore, the indication information carried by LP-WUS and the design of the reception process need to be further discussed in the Work Item (WI) stage.
[0006] Therefore, how to reduce the resource overhead of LP-WUS signal transmission is an urgent problem to be solved.

[0122] In order to facilitate a clearer understanding of the various embodiments of the present disclosure, some relevant technical knowledge is first introduced as follows.
[0123] 1) Rel-19 LP-WUS WI target
[0124] The scope of the Release 19 WI project identifies the need to standardize LP-WUS signals generated jointly using ASK / FSK and OFDM. The design of the LP-WUS indication paging reception process in RRC_IDLE / INACTIVE mode requires research, including the design of the LP-WUS bearer indication information, related configuration information, and terminal grouping methods.
[0125] 2) Rel-17 DCI 2_7 indicates that the terminal receives the wake-up indication signal design of Paging
[0126] Figure 1 is a schematic diagram of the Rel-17 DCI 2_7 indication PO reception process provided by the relevant technology. As shown in Figure 1, in the discussion of the Rel-17 terminal energy-saving technology, DCI 2_7 in RRC_IDLE mode is determined as an advance paging indication, and an energy-saving technology that indicates whether the terminal group under multiple POs receives paging information at the PO position can save the power consumption overhead of unnecessary paging reception of the terminal.
[0127] Figure 2 is a design diagram of the DCI 2_7 indication field provided by the related technology. As shown in Figure 2, the terminal receives DCI 2_7 and determines whether to receive paging information at the PO position based on the wake-up indication information at the bit position in the wake-up indication information field corresponding to DCI 2_7. The bit position 0 corresponding to Sub_group indicates not waking up, and the bit position 1 corresponding to Sub_group indicates waking up to receive Paging.
[0128] Figure 3 is a schematic diagram of a terminal receiving paging within a paging cycle provided by the related art. As shown in Figure 3, in RRC_IDLE / INACTIVE mode, the DCI 2_7 standardized by Rel-17 can instruct the terminal to receive paging at the PO. The DCI 2_7 signal generated based on the PDCCH can simultaneously indicate the awakening or dormancy of subgroups under multiple POs through a bitmap indication method. Rel-19 requires a standardized LP-WUS signal generated based on ASK / FSK and OFDM signals to instruct the terminal to receive paging messages. The following problems exist in the design of the indication information and the terminal reception process:
[0129] The LP-WUS signal's information carrying capacity is far inferior to that of the PDCCH signal (one symbol can carry a maximum of four bits of indication information). If the LP-WUS signal carries subgroup-level wake-up indication information similar to that carried by DCI-based DCI 2_7, it would result in significant LP-WUS transmission resource overhead and also increase power consumption on the base station side. Therefore, when the LP-WUS instructs the terminal to wake up to receive the Paging indication information, it is necessary to design the indication information and related processes carried by the LP-WUS.
[0130] To address the above problems, this solution proposes a transmission method for a first signal (LP-WUS) generated based on ASK / FSK and OFDM sequences, which is used to instruct at least one terminal group in RRC_IDLE / INACTIVE mode to determine whether to wake up and receive DCI 2_7 (PEI) or PO, or in RRC_CONNECTED mode, the wake-up information of the LP-WUS with UE-group indication granularity indicates at least one terminal group to determine whether to wake up and start receiving PDCCH and / or start receiving the time domain location information of PDCCH.
[0131] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.
[0132] FIG4 is a flowchart of a low-power wake-up signal transmission method according to an embodiment of the present disclosure. As shown in FIG4 , the low-power wake-up signal transmission method is applied to a terminal. The low-power wake-up signal transmission method may include step 401.
[0133] Step 401: Based on first configuration information sent by a network-side device, obtain at least one first signal; the first signal carries wake-up indication information, and the wake-up indication information is used to wake up the terminal.
[0134] It should be noted that the embodiments of the present disclosure can be applied to a scenario in which a terminal is awakened, where the terminal includes a master device and a low-power wake-up receiver (LP-WUR). The first signal can be a low-power wake-up signal (LP-WUS). Waking up the terminal indicates waking up the master device of the terminal so that the awakened master device receives the second signal.
[0135] Optionally, the first signal is generated based on a first sequence; the first sequence is a receiving sequence jointly generated based on amplitude shift keying (ASK) / frequency shift keying (FSK) and orthogonal frequency division multiplexing (OFDM) sequence.
[0136] Specifically, the first signal can be generated based on a first sequence, wherein the first sequence is a receiving sequence jointly generated based on amplitude-shift keying (ASK) / frequency-shift keying (FSK) and orthogonal frequency division multiplex (OFDM).
[0137] Optionally, the second signal includes at least one of the following:
[0138] (1) Paging advance indication signal, for example, DCI 2_7;
[0139] (2) Paging message, i.e. receiving paging at a paging opportunity (PO);
[0140] (3) Scheduling downlink control information (DCI);
[0141] (4) Non-scheduled DCI, for example, DCI 2_6.
[0142] The network-side device sends first configuration information to the terminal, where the first configuration information is used by the terminal to receive the first signal, that is, to receive the first signal at at least one time-frequency resource location of the first signal, for example, to receive LP-WUS at LP-WUS-MO.

For example, the target bit information is 1-bit information, and the 1-bit information indicates that 4 consecutive paging subgroups, such as paging subgroup #0, paging subgroup #1, paging subgroup #2, and paging subgroup #3, are awakened or dormant at the same time. Alternatively, the 1-bit information indicates that 4 consecutive paging occasions, such as PO 1, PO 2, PO 3, and PO 4, are awakened or dormant at the same time. Alternatively, the 1-bit information indicates that 4 consecutive paging frames, such as PF #0, PF #1, PF #2, and PF #3, are awakened or dormant at the same time.
[0250] (b) first indication information, used to indicate one or more of the number or index value of consecutive paging subgroup groups associated with the first signal, the number or index value of paging subgroups, the number or index value of POs, and the number or index value of PFs; the paging subgroup group includes K consecutive paging subgroups; and K is a positive integer.
[0251] Specifically, the first signal is associated with a continuous paging subgroup group, a paging subgroup, a PO, or a PF; wherein the paging subgroup group includes K continuous paging subgroups, and K is a positive integer. The first signal is associated with the number K1 or index value of continuous paging subgroup groups, the number K1 or index value of paging subgroups, the number K1 or index value of POs, and the number K1 or index value of PFs.
[0252] For example, the first signal is associated with paging subgroup group 0 and paging subgroup group 1, wherein paging subgroup group 0 and paging subgroup group 1 respectively include four paging subgroups, namely, paging subgroup #0, paging subgroup #1, paging subgroup #2, and paging subgroup #3.
[0253] (c) second indication information, used to indicate the bit length of the first signal.
[0254] Specifically, the bit length K2 of the first signal is, for example, 4 bits, that is, the first signal is a 4-bit signal.
[0255] (d) The third indication information is used to indicate the correspondence between the dedicated wake-up sequence and the index value of the paging subgroup, the index value of the PO, or the index value of the PF.
[0256] Specifically, a dedicated wake-up sequence corresponds to a terminal-specific wake-up sequence, or a dedicated wake-up sequence corresponds to a terminal group-specific wake-up sequence. For example, dedicated wake-up sequence Seq_0 corresponds to subgroup_0 and subgroup_1, dedicated wake-up sequence Seq_1 corresponds to subgroup_2 and subgroup_3, dedicated wake-up sequence Seq_2 corresponds to subgroup_4 and subgroup_5, and dedicated wake-up sequence Seq_3 corresponds to subgroup_6 and subgroup_7.
[0257] (e) Fourth indication information, used to indicate the length of the dedicated wake-up sequence.
[0258] (f) Fifth indication information, used to indicate the number of the exclusive wake-up sequences included in the first signal.
[0259] For example, if the number of exclusive wake-up sequences included in the first signal is 3, the length of the exclusive wake-up sequence included in the first signal is the sum of the length of each exclusive wake-up sequence in the 3 exclusive wake-up sequences.
[0260] (g) sixth indication information, used to indicate generation information of a dedicated wake-up sequence included in the generation of the first signal; wherein the generation information includes at least one of the following: a cyclic shift set, the cyclic shift set including P different cyclic shift values, where P is a positive integer; a target value, the target value being related to at least one of the first indication information, a cell identifier Cell_ID, and a terminal identifier UE_ID; a base sequence format, the base sequence including a first base sequence or a second base sequence; and a correspondence between the dedicated wake-up sequence and the wake-up terminal. For example, the first base sequence is an m-sequence, and the second base sequence is a GOLD sequence.
[0261] (h) seventh indication information, used to indicate modulation and coding information generated by the first signal, the modulation and coding information including at least one of the following: 1) modulation mode, such as discrete Fourier transform (DFT) / fast Fourier transform (FFT) information (for example, DFT / FFT size), quadrature phase shift keying (QPSK) / binary phase shift keying (BPSK) / other multi-level modulation information; 2) coding mode, for example, Manchester coding; 3) coding rate.

[0263] Specifically, the first configuration information may be cell-specific (Cell-specific), terminal-specific (UE-Specific) or terminal group-specific (UE group-Specific) information, and the first configuration information may be obtained through at least one of RRC signaling configuration, dynamic signaling activation / deactivation, dynamic signaling (for example, PDCCH, Physical Downlink Shared Channel (PDSCH)), and broadcast signaling (System Information Block-X (SIB-X), Physical Broadcast Channel (PBCH)).
[0264] Optionally, the carrying manner of the wake-up indication information includes any one of the following: a bitmap, and the dedicated wake-up sequence.
[0265] Optionally, bit 0 corresponding to the receiving position of the wake-up indication information indicates that the terminal continues to sleep; bit 1 corresponding to the receiving position of the wake-up indication information indicates waking up the terminal.
[0266] Optionally, the method further includes:
[0267] After the terminal receives the first signal carrying the wake-up indication information, a second signal is sent to the terminal.
[0268] Specifically, after the terminal receives the first signal carrying the wake-up indication information, the terminal may be awakened based on the wake-up indication information. After the terminal wakes up, the network side device may send a second signal to the terminal.
[0269] In the embodiment of the present disclosure, the network side device sends a second signal to the terminal after the terminal receives the first signal carrying the wake-up indication information, thereby implementing the behavior design of the terminal after wake-up, thereby achieving effective transmission of the signal.
[0270] Next, the low-power wake-up signal transmission method provided by the present disclosure will be further described through specific embodiments.
[0271] Example 1: LP-WUS carries wake-up indication information at the paging subgroup level based on bitmap
[0272] Step 1. The network-side device (base station side) sends first configuration information to at least one terminal. The first configuration information is used for the terminal to receive the first signal and obtain the wake-up indication information. The network-side device then sends the LP-WUS carrying the wake-up indication information to at least one terminal. The first configuration information can be Cell-specific, UE-Specific or UE group-Specific information. The first configuration information can be obtained through RRC signaling configuration, or dynamic signaling activation / deactivation, dynamic signaling (such as PDCCH or PDSCH) and broadcast signaling (such as SIB-X or PBCH). The LP-WUS signal is an LP-WUR exclusive signal generated based on the ASK / FSK signal and the OFDM sequence.
[0273] Step 2: LP-WUR determines the receiving position of the wake-up indication information carried in at least one first signal (LP-WUS) generated based on ASK / FSK and OFDM sequence according to the first configuration information, and obtains the wake-up indication information based on the receiving position.
[0274] 2.1 The terminal determines at least one time-frequency resource location (LP-WUS-MO) of a group of TDM and / or FDM mixed LP-WUS reception opportunities (LP-WUS-O) according to the first configuration information; wherein, an LP-WUS-O includes at least one continuous or non-continuous LP-WUS-MO. If the LP-WUS-MO is a non-continuous time-frequency resource in the frequency domain and / or time domain, the first configuration information will configure the time domain offset and / or frequency domain offset between the LP-WUS-MOs.
[0275] 2.2 Receive the LP-WUS on the LP-WUS-MO determined in step 2.1, the terminal determines the bit position of the wake-up indication information in the LP-WUS, and obtains the wake-up indication information at the bit position.
[0276] 2.3 The method for the terminal to obtain the wake-up indication information based on the first signal is as follows: the wake-up indication information of the first signal is carried based on a bitmap, the terminal determines the bit position of the wake-up indication information in the first signal based on the first configuration information, and obtains the wake-up indication information at the bit position.
[0277] The first configuration information may include at least one of the following:
[0278] Target bit information, used to indicate the number K0 or index value of any one of the number of consecutive paging subgroups, the number of consecutive POs, and the number of consecutive PFs that are simultaneously awakened or dormant as indicated by the wake-up indication information in the first signal (LP-WUS). For example, the target bit information is 1-bit wake-up indication information;
[0279] First indication information, used to indicate the number K1 or index value of any one of the consecutive paging subgroup groups (one paging subgroup group includes K consecutive paging subgroups) associated with the first signal (LP-WUS);
[0280] The second indication information is used to indicate the bit length K2 of the first signal (LP-WUS).
[0281] The specific method for the terminal to determine the bit position of the wake-up indication information in the first signal is considered in the following three cases:
[0282] Case 1: When only K0 and K2 are configured and K0 is the number of consecutive paging subgroups associated with the LP-WUS signal, the terminal uses the above formula (1) to determine the bit position;
[0283] Case 2: When only K0 and K2 are configured and K0 is the number of consecutive POs associated with the LP-WUS signal, the terminal uses the above formula (2) to determine the bit position;
[0284] Case 3: When only K0 and K2 are configured and K0 is the number of consecutive PFs associated with the LP-WUS signal, the terminal uses the above formula (3) to determine the bit position;
[0285] Case 4: Only K1 and K2 are configured, and the associated granularity of K1 is the number of consecutive paging subgroups, POs, or PFs. The terminal replaces K0 in the above formulas (1) to (3) with K1 / K2; or, when the associated granularity of K1 is a consecutive paging subgroup group (a paging subgroup group includes K consecutive paging subgroups), the terminal uses the above formula (4) to determine the bit position.
[0286] It should be noted that bit 0 of the wake-up indication information indicates that the terminal continues to sleep, and bit 1 of the wake-up indication information indicates that the terminal wakes up to receive the second signal, for example, DCI 2_7.
[0287] Step 3: The LP-WUR receives the LP-WUS signal on the LP-WUS-MO determined in step 2. After obtaining the wake-up indication information, the corresponding terminal behavior includes one or more of the following:
[0288] Behavior 1: As long as the LP-WUS containing the wake-up indication information is successfully received on one LP-WUS-MO, the MR is awakened to receive DCI 2_7, scheduled DCI or non-scheduled DCI, and the terminal stops blindly detecting the LP-WUS on subsequent LP-WUS-MOs.
[0289] Behavior 2: As long as the LP-WUS containing the wake-up indication information is successfully received on one LP-WUS-MO, the MR is awakened to receive DCI 2_7, scheduled DCI or non-scheduled DCI, and the terminal continues to blindly detect the LP-WUS on subsequent LP-WUS-MOs.
[0290] Action 3: If no LP-WUS is received at all the time-frequency resource positions of LP-WUS-MO, the MR continues to sleep.
[0291] Action 4: When the LP-WUS signal carrying the sleep indication information is received at the time-frequency resource position of the LP-WUS-MO, the MR continues to sleep.
[0292] Action 5: If no LP-WUS is received at all the time-frequency resource positions of LP-WUS-MO, the MR automatically wakes up and receives DCI 2_7, scheduled DCI or non-scheduled DCI.
[0293] Behavior 6: The MR will continue to sleep only if it receives the LP-WUS signal carrying the sleep indication information on the LP-WUS-MO; otherwise, the MR automatically wakes up to receive DCI 2_7, scheduled DCI, or non-scheduled DCI.
[0294] Example 2: LP-WUS carries paging subgroup-level wake-up indication information based on a dedicated wake-up sequence
[0295] Step 1: The network side device (base station side) sends first configuration information to at least one terminal, where the first configuration information is used for the terminal to receive a first signal and obtain wake-up indication information; the network side device then sends an LP-WUS carrying the wake-up indication information to at least one terminal.
[0296] The first configuration information may be Cell-specific, UE-Specific, or UE group-Specific information. The first configuration information may be obtained through RRC signaling configuration, or at least one of dynamic signaling activation / deactivation, dynamic signaling (e.g., PDCCH or PDSCH), and broadcast signaling (e.g., SIB-X or PBCH). The LP-WUS signal is an LP-WUR-specific signal generated based on an ASK / FSK signal and an OFDM sequence. The LP-WUS signal carries the wake-up indication information in a dedicated wake-up sequence.
[0297] When the base station needs to wake up the terminal for transmission, it sends a dedicated wake-up sequence on the LP-WUS-MO associated with the terminal. Otherwise, the base station does not send any signal.
[0298] Step 2: LP-WUR determines the receiving position of the wake-up indication information carried in at least one first signal (LP-WUS) generated based on ASK / FSK and OFDM sequence according to the first configuration information, and obtains the wake-up indication information based on the receiving position.
[0299] 2.1 The terminal determines the time-frequency resource locations of a group of TDM and / or FDM mixed LP-WUS receiving opportunities (LP-WUS-O) according to the first configuration information; wherein, an LP-WUS-O includes at least one continuous or non-continuous LP-WUS-MO. If the LP-WUS-MO is a non-continuous time-frequency resource in the frequency domain and / or time domain, the first configuration information will configure the time domain offset and / or frequency domain offset between the LP-WUS-MO.
[0300] 2.2 The wake-up indication information of the first signal is carried in a dedicated wake-up sequence manner. The terminal determines the time-frequency resource position and the dedicated wake-up sequence for blind detection reception of the dedicated wake-up sequence based on the first configuration information.
[0301] The first configuration information may include at least one of the following:
[0302] The first indication information is used to indicate one or more of the number or index value of consecutive paging subgroup groups associated with the first signal (LP-WUS), the number or index value of paging subgroups, the number or index value of POs, and the number or index value of PFs; the paging subgroup group includes K consecutive paging subgroups; K is represented by K1; K is a positive integer;
[0303] The third indication information is used to indicate the correspondence between the dedicated wake-up sequence (LP-WUS sequence) and the index value of the paging subgroup, the index value of the PO, or the index value of the PF. For example, an LP-WUS sequence indicates the wake-up of one paging subgroup group (a paging subgroup group contains two paging subgroups). These paging subgroups can be sent simultaneously on the LP-WUS-MO or only one or at least one of them can be sent. Table 1 shows the correspondence between the LP-WUS sequence and the wake-up paging subgroup. As shown in Table 1 below, Seq_0 corresponds to Subgroup_0 and subgroup_1 wake-up, Seq_1 corresponds to Subgroup_2 and subgroup_3 wake-up, Seq_2 corresponds to Subgroup_4 and subgroup_5 wake-up, and Seq_3 corresponds to Subgroup_6 and subgroup_7 wake-up.
[0304] Table 1. Correspondence between LP-WUS sequence and wake-up paging subgroup
[0305] Fourth indication information, used to indicate the length L of the dedicated wake-up sequence (LP-WUS);
[0306] fifth indication information, used to indicate the number of the dedicated wake-up sequences included in the first signal;
[0307] Sixth indication information, used to indicate generation information of a dedicated wake-up sequence included in generation of the first signal (LP-WUS); wherein the generation information includes at least one of the following: a cyclic shift set, the cyclic shift set including P different cyclic shift values, where P is a positive integer; a target value, the target value being related to at least one of the first indication information, a cell identifier Cell_ID, and a terminal identifier UE_ID; a base sequence format, the base sequence including a first base sequence or a second base sequence; a correspondence between the dedicated wake-up sequence and the wake-up terminal;
[0308] The seventh indication information is used to indicate the modulation and coding information generated by the first signal, and the modulation and coding information includes at least one of the following: 1) modulation mode, such as discrete Fourier transform (DFT) / fast Fourier transform (FFT) information (for example, DFT / FFT size), quadrature phase shift keying (QPSK) / binary phase shift keying (BPSK) / other multi-level modulation information; 2) coding mode, such as Manchester coding; 3) coding rate.
[0309] The method for generating a dedicated wake-up sequence is as follows:
[0310] Sequence generation method 1: Using the first base sequence (m-sequence) as the base sequence, a dedicated wake-up sequence is generated by cyclic shifting by a value y. The cyclic shift value y is related to at least one of the length L and K1 of the dedicated wake-up sequence and a cyclic shift set generated based on the LP-WUS signal. Specific methods include, but are not limited to, one of the following:
[0311] The cyclic shift value y is the number of terminals in the paging subgroup, paging subgroup, PO, or PF, or the index value X, where y = ceil(L / k), k = {1, ..., K1-1}; or the cyclic shift value y is the i-th cyclic shift value in the cyclic shift set, where i = X mod P, i = {1, ..., P-1};
[0312] Sequence generation method 2: Using the second base sequence (GOLD sequence) as the base sequence, a dedicated wake-up sequence is obtained based on a target value h, where the target value h is related to at least one of K1, Cell_ID, and UE_ID.
[0313] Sequence generation method three: The exclusive wake-up sequence is the index of the associated paging subgroup group, and the value of the exclusive wake-up sequence is 0 to (K1-1); for example, an LP-WUS signal indicates 8 paging subgroup groups, and the index range of the paging subgroup group is 000 to 111. When waking up paging subgroup group 0 and paging subgroup group 7, the exclusive wake-up sequence (wake-up indication information field) is 000110.
[0314] Step 3: The LP-WUR receives the LP-WUS signal on the LP-WUS-MO determined in step 2. After obtaining the wake-up indication information, the corresponding terminal behavior includes one or more of the following:
[0315] 3.1 At least one dedicated wake-up sequence can be associated with a time-frequency resource location LP-WUS-MO. These dedicated wake-up sequences can be sent in series on this LP-WUS-MO at the same time according to the needs of the base station, or only one of the dedicated wake-up sequences or part of the dedicated wake-up sequences can be sent. The specific dedicated wake-up sequence sent can be based on the resource length of the LP-WUS-MO configured on the base station side. For example, LP-WUS-MO can send up to three dedicated wake-up sequences at the same time. Table 2 shows the correspondence between dedicated wake-up sequences and wake-up paging subgroups. As shown in Table 2, if the dedicated wake-up sequences corresponding to the paging subgroups to be awakened do not exceed three, the base station can simultaneously send the dedicated wake-up sequences corresponding to the wake-up paging subgroups; otherwise, the base station can only send three dedicated wake-up sequences on this LP-WUS-MO according to the implementation, and the other dedicated wake-up sequence is sent on the next LP-WUS-O.
[0316] Table 2. Correspondence between exclusive wake-up sequence and wake-up paging subgroup
[0317] 3.2 After the terminal receives the LP-WUS on the LP-WUS-MO and obtains the wake-up indication information, the corresponding terminal behavior includes one or more of the following:
[0318] Behavior 1: As long as an LP-WUS containing a dedicated wake-up sequence is successfully received on an LP-WUS-MO, the MR is woken up to receive DCI 2_7, scheduled DCI or unscheduled DCI, and the terminal stops blindly detecting LP-WUS on subsequent LP-WUS-MOs.
[0319] Behavior 2: As long as the LP-WUS containing the dedicated wake-up sequence is successfully received on one LP-WUS-MO, the MR is woken up to receive DCI 2_7, scheduled DCI or non-scheduled DCI, and the terminal continues to blindly detect LP-WUS on subsequent LP-WUS-MOs.
[0320] Behavior 3: If no LP-WUS containing a dedicated wake-up sequence is received at all LP-WUS-MO time-frequency resource positions, the MR automatically wakes up to receive DCI 2_7 scheduled DCI or non-scheduled DCI.
[0321] Action 4: If no LP-WUS is received at all the time-frequency resource positions of LP-WUS-MO, the MR continues to sleep.
[0322] Example 3: LP-WUS signal design in RRC_CONNECTED mode
[0323] Step 1: The network side device (base station side) sends the first configuration information to at least one terminal, and the first configuration information is used for the terminal to receive the first signal to obtain the wake-up indication information; the network side device then sends the LP-WUS carrying the wake-up indication information to at least one terminal. Among them, the first configuration information can be Cell-specific, UE-Specific or UE group-Specific information. For terminals in RRC_CONNECTED mode, LP-WUS can use each broadband part (per BWP) to configure the UE-Specific LP-WUS receiving time-frequency resource location (LP-WUS-MO). LP-WUS only carries at least one of the wake-up indication information, secondary cell dormancy (Scell dormancy) and PDCCH monitoring adaptation (Monitoring adaptation) indication information of one terminal; it can also configure the UE group Common LP-WUS-MO to carry the wake-up indication information of at least one terminal. The LP-WUS signal is a LP-WUR exclusive signal generated based on the ASK / FSK signal and the OFDM sequence.
[0324] Step 2: LP-WUR determines the receiving position of the wake-up indication information carried in at least one first signal (LP-WUS) generated based on ASK / FSK and OFDM sequence according to the first configuration information, and obtains at least one of the wake-up indication information, Scell dormancy and PDCCH Monitoring adaptation indication information.
[0325] 2.1 The terminal determines the time-frequency resource location of a group of TDM and / or FDM mixed LP-WUS receiving opportunities (LP-WUS-O) based on the first configuration information; wherein, an LP-WUS-O contains at least one continuous or non-continuous LP-WUS-MO. If the LP-WUS-MO is a non-continuous time-frequency resource in the frequency domain and / or time domain, the first configuration information will configure the time domain offset and / or frequency domain offset between the LP-WUS-MOs. Among them, the LP-WUS-MO can be a UE-Specific configuration or a UE group Common configuration.
[0326] 2.2. Receive the LP-WUS on the LP-WUS-MO determined in step 2.1. The terminal determines the bit position of the wake-up indication information in the LP-WUS and obtains at least one of the wake-up indication information, Scell dormancy, and PDCCH Monitoring adaptation indication information at the bit position.
[0327] The terminal receives the LP-WUS signal and obtains the wake-up indication information in the following two cases:
[0328] Case 1 (UE-Specific LP-WUS): The LP-WUS signal includes at least one of the wake-up indication field, Scell dormancy, and PDCCH Monitoring adaptation indication information field. The bit length and bit position of each information field are determined based on the protocol agreement or the first configuration information.
[0329] Case 2 (UE group-specific LP-WUS): The LP-WUS signal determines the wake-up indication information based on a bitmap or a terminal (group)-specific wake-up sequence; wherein, the bitmap can indicate one or a group of terminals based on 1 bit, and the bit position of the terminal or group of terminals can be determined based on protocol pre-definition or first configuration information. It should be noted that the indication method of the dedicated wake-up sequence is the same as that in Example 2 and will not be repeated here.
[0330] Step 3: The LP-WUR receives the LP-WUS signal on the LP-WUS-MO determined in step 2. After obtaining the wake-up indication information, the corresponding terminal behavior includes one or more of the following:
[0331] Behavior 1: As long as the LP-WUS containing the wake-up indication information is successfully received on one LP-WUS-MO, the MR is awakened to receive DCI 2_6, scheduled DCI or non-scheduled DCI, and the terminal stops blindly detecting the LP-WUS on subsequent LP-WUS-MOs.
[0332] Behavior 2: As long as the LP-WUS containing the wake-up indication information is successfully received on one LP-WUS-MO, the MR is awakened to receive DCI 2_6, scheduled DCI or non-scheduled DCI, and the terminal continues to blindly detect the LP-WUS on subsequent LP-WUS-MOs.
[0333] Action 3: If no LP-WUS is received at all the time-frequency resource positions of LP-WUS-MO, the MR continues to sleep.
[0334] Action 4: When the LP-WUS signal carrying the sleep indication information is received at the time-frequency resource position of the LP-WUS-MO, the MR continues to sleep.
[0335] Action 5: If no LP-WUS is received at all the time-frequency resource positions of LP-WUS-MO, the MR automatically wakes up to receive DCI 2__6, scheduled DCI or non-scheduled DCI.
[0336] Behavior 6: The MR will continue to sleep only if it receives the LP-WUS signal carrying the sleep indication information on the LP-WUS-MO; otherwise, the MR automatically wakes up to receive DCI 2_6, scheduled DCI, or non-scheduled DCI.
