[0003] The concepts of Low Power Wake-up Signal (LP-WUS) and Low Power Wake-Up Receiver (LP-WUR) can further reduce terminal power consumption based on existing energy-saving technologies. When there is no service transmission at the base station and terminal, the power-intensive Main Radio (MR) is turned off, while the LP-WUR device is turned on to receive the low-power signal sent by the base station. When there is service transmission, the base station activates the MR through LP-WUS to complete the service transmission. This can significantly save terminal power consumption when there is no service transmission.

[0028] In this disclosure, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0029] In this disclosure, the term "multiple" refers to two or more, and other quantifiers are similar.

[0030] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0031] To facilitate understanding of the solutions disclosed herein, the relevant content involved in this disclosure will be introduced first.

[0032] LP-WUS signal generation

[0033] Related technical research is based on the generation method of LP-WUS and Low Power Synchronizing Signal (LP-SS) by superimposing OFDM waveforms with OOK waveforms. The OOK waveform needs to be standardized into OOK-1 waveforms (see Figure 1) and OOK-4 waveforms (see Figure 2). The OOK waveform carries the wake-up indication information of OOK-based LP-WUS. Whether the OFDM sequence carries OFDM-based LP-WUS wake-up indication information, and if so, how it does so, requires further research.

[0034] OOK-1 waveform: One OFDM symbol corresponds to one single-bit. The method of mapping LP-WUS to a subcarrier (SC) is as follows:

[0035] OOK=1 means that all SCs are used for modulation, and an OFDM sequence is superimposed on the SC. This OFDM sequence carries part or all of the LP-WUS indication information.

[0036] OOK=0 means that all SCs have zero power (from the baseband perspective).

[0037] OOK-4 waveform: M-bit OOK-4 is generated in the time domain. The signal needs to undergo Discrete Fourier Transform (DFT) / least squares transform before being mapped to N SCs. OFDM sequence is superimposed at the position where the bit value is 1. This OFDM sequence carries part or all of the LP-WUS indication information.

[0038] The LP-WUS signal generation sequence is generated by superimposing OFDM waveforms at the OOK ON bit positions. The jointly generated sequence is mapped onto the time-frequency domain resource positions and then transmitted after undergoing an Inverse Fast Fourier Transform (IFFT), as shown in Figure 3. OOK-based LP-WUS acquires the information carried by LP-WUS based on the ON / OFF pattern of the OOK symbols; OFDM-based LP-WUS acquires the information carried by LP-WUS based on the OFDM waveform sequence superimposed at the resource positions mapped from the OOK symbols.

[0039] In related technologies, in Radio Resource Control (RRC) idle (RRC_IDLE) mode or in RRC inactive (RRC_INACTIVE) mode, the downlink control information (DCI) 2_7 in some cases is a downlink control signal generated based on OFDM signals. The wake-up indication field in the signal, based on a bitmap, simultaneously indicates whether multiple terminal groups are awake and receiving paging messages at the paging opportunity (PO) location. In Radio Resource Control connected (RRC_CONNECTED) mode, the DCI 2_6 in some cases is a downlink control signal generated based on OFDM signals. The wake-up indication field in the signal, based on a bitmap, simultaneously indicates whether multiple terminals have enabled discontinuous reception (DRX) activation to receive downlink data.

[0040] There are no sequence generation rules for low-power signal generation sequences in New Radio (NR) systems, and there is currently no solution on how to achieve the information carrying of low-power signal generation sequences.

[0041] To address the aforementioned technical problems, this disclosure provides an information processing method, transmission method, device, and medium. The method and device are based on the same application concept. Since the methods and devices solve problems in similar principles, their implementations can be mutually referenced, and repeated details will not be elaborated further.

[0042] Figure 4 shows a flowchart of the information processing method provided in this embodiment of the present disclosure. This method is applied to a first terminal, meaning it is executed by the first terminal. Specifically, the method of this disclosure may include:

[0043] Step 401: Determine the generation sequence of the first waveform carried by the first signal according to the predefined rules and / or the first configuration information. The generation sequence of the first waveform carries wake-up indication information of at least one terminal or terminal group. The first waveform includes at least one of the following: On / Off Keying (OOK) waveform, Frequency Shift Keying (FSK) waveform, Quadrature Phase Shift Keying (QPSK) waveform, and Orthogonal Frequency Division Multiplexing (OFDM) waveform.

[0044] Step 402: Based on the generation sequence of the first waveform, obtain the first wake-up indication information and / or at least part of the cell index information.

[0045] The information processing method of this disclosure embodiment determines the generation sequence of a first waveform carried by a first signal according to predefined rules and / or first configuration information. The generation sequence of the first waveform carries wake-up indication information of at least one terminal or terminal group. The first waveform includes at least one of the following: On / Off Keying (OOK) waveform, Frequency Shift Keying (FSK) waveform, and Quadrature Phase Shift Keying (QPSK) waveform. Based on the generation sequence of the first waveform, first wake-up indication information and / or at least part of cell index information are obtained. In this way, the information carried by the generation sequence of the first waveform can be determined through predefined rules and / or first configuration information, thus solving the information carrying problem of the generation sequence of low-power signals.

[0046] In some embodiments, the first signal is LP-WUS or a low-power synchronization signal (LP-SS).

[0047] Here, the predefined rules can be pre-agreed upon by the protocol. The first configuration information can be pre-configured by the base station for the first terminal. It should be understood that the first sequence generated by the first waveform is also a sequence generated based on the first waveform. In some embodiments, the first sequence generated by the first waveform is a sequence generated based on an OOK waveform, an FSK waveform, or a QPSK waveform. Generally, the first sequence generated by the first waveform is a sequence generated based on an OOK waveform. In some embodiments, at least one terminal or terminal group is associated with a Monitoring Occasion (MO group).

[0048] The first signal is generated based on a generation sequence of the first waveform. It should be understood that the generation sequence can consist of one or more first waveforms, and the generation sequence can be one or more. That is, a generation sequence is composed of one or more first waveforms. The generation sequence carried by the first signal can be one or more.

[0049] The first terminal demodulates the generation sequence of the first waveform according to predefined rules and / or first configuration information, determines the correspondence between the information carried in the sequence and the terminal (group), and thereby obtains the first wake-up indication information and / or at least some cell index information from the generation sequence of the first waveform. Afterwards, the first terminal can perform corresponding operations based on the wake-up indication of the first wake-up indication information (e.g., wake up or not wake up the terminal), or it can determine the location of the terminal or terminal group in the generation sequence carried by the first signal based on at least some cell index information, obtain the first wake-up indication information, and perform corresponding operations (e.g., wake up or not wake up the terminal).

[0050] It should be understood that the generation sequence of the first waveform can carry cell index information associated with at least one terminal or group of terminals. The first terminal can obtain at least part of the cell index information based on the generation sequence of the first waveform.

[0051] In some embodiments, the first configuration information includes at least one of the following:

[0052] The temporal location information of the first signal;

[0053] Frequency domain position information of the first signal;

[0054] The generation information of the generation sequence of the first waveform.

[0055] Here, the time-frequency domain resources (time-domain location information, frequency-domain location information) of the first signal are used by the first terminal to receive the first signal transmitted by the base station. The generation information of the generation sequence of the first waveform can be used by the first terminal to demodulate the generation sequence of the first waveform.

[0056] In some embodiments, the generation information of the generation sequence of the first waveform includes at least one of the following:

[0057] Sequence type;

[0058] Sequence length;

[0059] At least one encoding method;

[0060] At least one coding bitrate;

[0061] At least one sequence generation parameter, wherein the sequence generation parameter includes, but is not limited to, at least one of cyclic shift (CS) and sequence generation initial value;

[0062] Base sequence;

[0063] Waveform parameters, here, waveform parameters may include: OOK waveform parameters, such as OOK waveform type (including OOK-1, OOK-4 or others), M (representing the number of OOK chips / bits of an OFDM symbol transmission), and at least one of DFT / Least Squares (LS) size.

[0064] Sequence generation rules.

[0065] It should be noted that if the base station is not configured with the first configuration information, the predefined rules include the contents contained in the first configuration information.

[0066] In some embodiments, the generation sequence of the first waveform is generated based on at least one of a first sequence, a bitmap, and a binary sequence.

[0067] In some embodiments, the first sequence is one of the following sequences: M sequence, GOLD sequence, Walsh sequence, PN sequence, ZC sequence.

[0068] In some embodiments, the correspondence between the generation sequence of the first waveform and the at least one terminal or terminal group is determined by predefined rules and / or a preset threshold value for the number of terminals or terminal groups and / or first configuration information, and the correspondence between the generation sequence of the first waveform and the at least one terminal or terminal group is used to determine the first wake-up indication information and / or at least some cell index information.

[0069] The predefined rule is related to at least one of the following: wake-up indication information category, listening opportunity MO index, listening opportunity MO group index, listening opportunity MO group intra-index, number of terminal groups under a paging opportunity PO, number of candidate sequences of the generation sequence of the first waveform, number of parameters of the generation sequence of the first waveform, number of terminals or terminal groups associated with a first signal opportunity (LO), number of terminals or terminal groups associated with the first signal, number of POs associated with the first signal, and number of DRXs associated with the first signal.

[0070] That is, the first terminal determines the correspondence between the generation sequence of the first waveform and the at least one terminal or terminal group according to predefined rules and / or preset threshold values ​​for the number of terminals or terminal groups and / or first configuration information; then, based on the correspondence between the generation sequence of the first waveform and the at least one terminal or terminal group, it determines the first wake-up indication information and / or at least some cell index information.

[0071] If the correspondence between the generation sequence of the first waveform and the at least one terminal or terminal group is determined by a predefined rule and a preset threshold value for the number of terminals (groups), then specifically: if the number of terminals (groups) under a paging opportunity PO is greater than or equal to the preset threshold value P for the number of terminals (groups), then the correspondence between the generation sequence of the first waveform and the at least one terminal or terminal group is determined based on predefined rule one; otherwise, it is determined based on predefined rule two.

[0072] In some embodiments, the wake-up indication information category includes at least one of terminal-specific wake-up indication information, terminal group-specific wake-up indication information, and common wake-up indication information;

[0073] The first wake-up indication information is either common wake-up indication information or terminal (group) specific wake-up indication information. The common wake-up indication information is the wake-up indication of all terminals or terminal groups associated with the first signal, and the specific wake-up indication information is the wake-up indication for at least one specific terminal or at least one specific terminal group.

[0074] In some embodiments, if the generation sequence of the first waveform is generated based on the first sequence and / or bitmap method, at least one generation parameter of the first sequence is related to at least one of the following: wake-up indication information category, terminal index, terminal group index, number of terminals or terminal groups associated with a first signal opportunity (LO), number of terminals or terminal groups associated with a first signal, number of POs associated with a first signal, number of DRXs associated with a first signal, number of subgroups under a PO, number of terminal groups under a PO, cell identifier, MO index, MO group index, MO group intra-index, number of MO groups under a LO, and number of MOs under an MO group.

[0075] Here, the generation sequence of the first waveform carries wake-up indication information for at least one terminal or group of terminals. In some embodiments, where the generation sequence of the first waveform is generated based on the first sequence and / or a bitmap method, the wake-up indication information is determined based on bit indication information in the bitmap and / or the first sequence.

[0076] It should be noted that at least one generation parameter of the first sequence can be used to determine the correspondence between the generation sequence of the first waveform and the at least one terminal or terminal group.

[0077] It should be understood that, in Case 1, the generation sequence of the first waveform is generated based on the first sequence, and at least one generation parameter of the first sequence is related to at least one of the following: wake-up indication information category, terminal index, terminal group index, number of terminals or terminal groups associated with a first signal opportunity (LO), number of terminals or terminal groups associated with a first signal, number of POs associated with a first signal, number of DRXs associated with a first signal, number of subgroups under a PO, number of terminal groups under a PO, cell identifier, MO index, MO group index, MO group intra-index, number of MO groups under a LO, and number of MOs under an MO group.

[0078] In scenario two, the generation sequence of the first waveform is generated based on the first sequence and the bitmap. At least one generation parameter of the first sequence is related to at least one of the following: wake-up indication information category, terminal index, terminal group index, number of terminals or terminal groups associated with a first signal opportunity (LO), number of terminals or terminal groups associated with the first signal, number of POs associated with the first signal, number of DRXs associated with the first signal, number of subgroups under a PO, number of terminal groups under a PO, cell identifier, MO index, MO group index, MO group intra-index, number of MO groups under a LO, and number of MOs under an MO group.

[0079] It should be noted that the scheme design of this disclosure embodiment provides a correspondence between wake-up indication information and the first sequence, which can be used by the first terminal to obtain wake-up indication information.

[0080] Case 3: The first waveform generation sequence is generated based on a bitmap.

[0081] Based on the above situations one and two, or in cases where the generation method of the first waveform generation sequence includes the first sequence, in some embodiments, at least one generation parameter of the first sequence is determined by the first index and / or the first function.

[0082] The first index is the index of the candidate values ​​of the generation parameters of the first sequence or the index of the candidate sequence of the first sequence. The value of the first index is a predefined value, or the value of the first index is related to at least one of the following: the candidate values ​​of the generation parameters of the first sequence, the number of terminals or terminal groups associated with a first signal opportunity (LO), the number of terminals or terminal groups associated with the first signal, the number of POs associated with the first signal, the number of DRXs associated with the first signal, the number of terminals associated with the first signal, the number of subgroups under a PO, and the number of terminal groups under a PO.

[0083] Based on this, in some embodiments, when the first index is the index of the candidate values ​​of the generation parameters of the first sequence, and the wake-up indication information category is common wake-up indication information, the value of the first index is one of the following: 0, 1, K1-1, K1, where K1 represents the number of candidate values ​​of the generation parameters of the first sequence; or, K1 represents the number of terminals or terminal groups associated with the first signal, K1 = N1; or the value of the first index is one of the following: N su N su +1, N1, N1+1, N su This represents the number of subgroups under a PO or the number of terminal groups under a PO; or N su N1 represents the number of terminals or terminal groups associated with a first signal opportunity LO, wherein the LO consists of at least one MO and / or MO group; N1 represents the number of terminal groups;

[0084] In some embodiments, N su Based on the first configuration information and / or predefined rules, determine N. su The predefined rules are:

[0085] N su = Number of POs / DRXs associated with the first signal * Number of terminal groups under one PO; or,

[0086] N su = Number of terminals or terminal groups associated with a first signal opportunity LO * Number of terminal groups under a PO; or,

[0087] N su = (Number of terminals or terminal groups associated with a first signal opportunity LO * Number of terminal groups under a PO) / Number of MO groups under the next LO after a LO.

[0088] It should be noted that N mentioned later... su The specific method for determining this part is the same as described above, and will not be repeated hereafter.

[0089] Alternatively, if the first index is the index of the candidate values ​​of the generation parameters of the first sequence, and the wake-up indication information category is terminal or terminal group-specific wake-up indication information, the first index is a value other than the value corresponding to the common wake-up indication information.

[0090] That is, the correspondence between the candidate values ​​of the generation parameters of the first sequence and the indication information includes one of the following:

[0091] Relationship 1: The index i of the candidate value = K1 or K1-1 or 0 or 1 indicates that it corresponds to common wake-up indication information, such as N1 subgroups of user equipment (UE) waking up simultaneously. Other candidate values ​​with index i correspond to terminal- or terminal group-specific wake-up indication information.

[0092] At least one generation parameter of the first sequence described above is determined by a first index and / or a first function. In some embodiments, the generation parameter of the first sequence is equal to the value of the first function g(i). Here, g(i) is a function related to i, and the function operation may include one or more of the following: rounding, rounding up, rounding down, modulo, addition, subtraction, multiplication, and division.

[0093] In some embodiments, g(i) = i; or g(i) = i + 1; or g(i) = i mod K1; or g(i) = (i + 1) mod K1; g(i) = (i mod K1) + 1; or g(i) = (i + 1 mod K1) + 1; or g(i) = i * floor(L / K1); or g(i) = i * ceil(L / K1); or g(i) = i * floor(L / K1) + 1; or g(i) = i * ceil(L / K1) - 1; or g(i) = i mod ceil(N su +1 / R); or g(i)=(i+1)mod floor(N su +1 / R).

[0094] Where i represents the first index, L represents the length of the generated sequence of the first waveform, R represents the number of MO groups under one LO, and N su This represents the number of subgroups under a PO or the number of terminal groups under a PO; or N su This indicates the number of terminals or terminal groups associated with a first signal opportunity LO, where the LO consists of at least one MO and / or MO group; floor() represents the floor function, and ceil() represents the floor function.

[0095] Relationship 2: Index of candidate value i = N su or N su +1, N1, or N1+1 indicates that the corresponding value is a common wake-up indication. Other candidate values ​​at index i correspond to terminal- or terminal group-specific wake-up indications.

[0096] At least one generation parameter of the first sequence described above is determined by a first index and / or a first function. In some embodiments, the generation parameter of the first sequence is equal to the value of the first function g(i). Here, g(i) is a function related to i, and the function operation may include one or more of the following: rounding, rounding up, rounding down, modulo, addition, subtraction, multiplication, and division.

[0097] In some embodiments, g(i) = i*floor(L / K1); or g(i) = i*ceil(L / K1); or g(i) = i*floor(L / K1) + 1; or g(i) = i*ceil(L / K1) - 1; or g(i) = i*floor(L / ceil(N su +1 / R)); or g(i)=i*ceil(L / ceil(N su +1 / R)); or g(i)=i*floor(L / ceil(N su +1 / R))+1; or g(i)=i*ceil(L / ceil(N su +1 / R))-1.

[0098] Where i represents the first index, L represents the length of the generated sequence of the first waveform, R represents the number of MO groups under one LO, and N su This represents the number of subgroups under a PO or the number of terminal groups under a PO; or N su This indicates the number of terminals or terminal groups associated with a first signal opportunity LO, where the LO consists of at least one MO and / or MO group; floor() represents the floor function, and ceil() represents the floor function.

[0099] When the first index is the index of a candidate sequence of the first sequence, and the wake-up indication information category is common wake-up indication information, the value of the first index is one of the following: 0, 1, N1, N1+1, where N1 represents the number of terminal groups; or,

[0100] When the first index is the index of a candidate sequence of the first sequence, and the wake-up indication information category is terminal or terminal group-specific wake-up indication information, the first index is a value other than the value corresponding to the common wake-up indication information.

[0101] Here, the first sequence has N2 (N2≥N1+1) candidate sequences.

[0102] The correspondence between the candidate sequence index and the indicator information includes one of the following:

[0103] The sequence index i (i = 1 to N1 or i = 0 to N1-1) = 0, 1, N1, or N1+1 indicates common wake-up indication information, such as N1 subgroup UEs waking up simultaneously. Other candidate index values ​​for i correspond to terminal- or terminal group-specific wake-up indication information.

[0104] At least one generation parameter of the first sequence described above is determined by a first index and / or a first function. In some embodiments, the generation parameter of the first sequence is equal to the value of the first function g(i). Here, g(i) is a function related to i, and the function operation may include one or more of the following: rounding, rounding up, rounding down, modulo, addition, subtraction, multiplication, and division.

[0190] Example 2: Method 2 for generating the OOK sequence carried by the LP-WUS signal

[0191] Step 21: The terminal determines the reception information of the OOK sequence carried by the LP-WUS signal based on predefined rules and / or first configuration information. This reception information is used to receive and demodulate the OOK sequence.

[0192] The first configuration information includes at least one of the following: OOK waveform parameters, OOK sequence length L, OOK sequence type, encoding method, encoding rate R, time domain resource location of LP-WUS signal, frequency domain resource location of LP-WUS signal, and LP-WUS signal bandwidth.

[0195] Step 22: The terminal obtains wake-up indication information and / or at least part of the cell index information based on the OOK sequence carried by the LP-WUS signal.

[0196] The wake-up indication information includes at least one of the following types:

[0197] Terminal-specific wake-up indication information, used to wake up a specific terminal;

[0198] Terminal group-specific wake-up indication information is used to wake up at least one specific terminal group, which may be at least one subgroup under a PO, at least one terminal group under a PO, at least one terminal group associated with LP-WUS, or a terminal group determined by other means.

[0199] The public wake-up instruction is used to wake up all terminals or terminal groups that receive this LP-WUS.

[0200] The OOK sequence is generated based on the bitmap and / or at least one first sequence, meaning that the bitmap and / or at least one first sequence jointly carry the wake-up indication information.

[0201] In some embodiments, the bitmap carries at least one of wake-up indication information and a portion of the cell identifier, and the specific indication method includes one of the following:

[0202] Method 1: LP-WUS is an N1-bit bitmap, where each bit corresponds to a terminal or a terminal group; a bit value of 0 represents sleep, and a bit value of 1 represents wake-up. The bit index of the bitmap indicator field containing the wake-up indication information of the terminal or terminal group is related to at least one of the following: terminal group index, terminal index, number of MO groups under one LO, and number of terminals or terminal groups N1 associated with LP-WUS.

[0203] Example 1: An LP-WUS is associated with a PO. The length of the bitmap indicator field of the LP-WUS is the same as the number of terminal groups under a PO. The bit index of the bitmap indicator field of the terminal group is related to the index of the PO under which the terminal group is located. It can be that the bit index of the bitmap indicator field of the terminal group is equal to the index of the PO under which the terminal group is located, or the index of the PO under which the terminal group is located + 1, or the index of the PO under which the terminal group is located - 1.

[0204] Example 2: An LP-WUS is associated with N1 subgroups under a PO. The length of the bitmap indicator field of the LP-WUS is the same as the number of terminal groups under a PO. The bit index of the bitmap indicator field of the terminal group is related to the index under the PO of the terminal group and N1. It can be that the bit index of the bitmap indicator field of the terminal group is equal to the index under the PO of the terminal group mod N1, or the index under the PO of the terminal group mod N1+1, or the index under the PO of the terminal group mod N1-1.

[0205] Example 3: An LP-WUS is associated with N1 subgroups under a PO. The length of the LP-WUS bitmap indicator field is the same as the number of terminal groups under a PO. The bit index of the bitmap indicator field of the terminal group is related to the index of the PO where the terminal group is located, the number of MO groups under a LO, and N1. It can be: bit index of the bitmap indicator field of the terminal group = index of the PO where the terminal group is located / number of MO groups under a LO mod N1 or ceil(index of the PO where the terminal group is located / number of MO groups under a LO) mod N1 or floor(index of the PO where the terminal group is located / number of MO groups under a LO) mod N1 or index of the PO where the terminal group is located / number of MO groups under a LO mod N1-1 or ceil(index of the PO where the terminal group is located / number of MO groups under a LO) mod N1-1 or floor(index of the PO where the terminal group is located / number of MO groups under a LO) mod N1-1 or index of the PO where the terminal group is located / number of MO groups under a LO mod N1-1 or N1+1 or ceil(index of the PO where the terminal group is located / number of MO groups under a LO) mod N1+1 or floor(index of the PO where the terminal group is located / number of MO groups under a LO) mod N1+1.

[0206] Method 2: LP-WUS consists of an N1-bit bitmap and an N2-bit sequence. Each bit in the N1 bits corresponds to a terminal or a group of terminals; the N2 bits carry part of the cell identification information; (for example: N2 = 2 bits, 00 corresponds to a cell with Cell-ID mod 4 = 0; 01 corresponds to a cell with Cell-ID mod 4 = 1; 10 corresponds to a cell with Cell-ID mod 4 = 2; 11 corresponds to a cell with Cell-ID mod 4 = 3).

[0207] The bit index of the bitmap indicator field containing the wake-up indication information of the terminal or terminal group is related to at least one of the following: terminal group index, terminal index, number of MO groups under a LO, and number of terminals or terminal groups associated with LP-WUS, N1 and N2.

[0208] Example 1: When the N2 bit sequence follows the N1 bit bitmap indication information field, the method for determining the bit position in the bitmap indication information field where the terminal or terminal group is located is the same as in Method 1;

[0209] Example 2: When the N2 bit sequence precedes the N1 bit map indication information field, the method for determining the bit position in the bit map indication information field where the terminal or terminal group is located is +N2;

[0210] Example 2.1: An LP-WUS is associated with a PO. The number of terminal groups under a PO is the same as the number of bitmap indicator fields of the LP-WUS. The bit index of the bitmap indicator field of the terminal group is related to the index of the PO of the terminal group. It can be that the bit index of the bitmap indicator field of the terminal group is equal to the index of the PO of the terminal group + N2, or the index of the PO of the terminal group + N2 + 1, or the index of the PO of the terminal group + N2 - 1.

[0211] Example 2.2: An LP-WUS is associated with N1 subgroups under a PO. The bitmap indicator field of the LP-WUS is the same as the number of terminal groups under a PO. The bit index of the bitmap indicator field of the terminal group is related to the index under the PO of the terminal group and N1.
