[0066] For the convenience of understanding, some contents related to the embodiments of the present application are described as follows:

[0067] I. Low power wake up receiver (LP WUR).

[0068] The basic working principle of the LP WUR is that the receiving end comprises a first module and a second module. The first module is a main communication module, used to receive and send communication data transmitted by the sending end. The second module is a low-power module, used to receive a low-power wake-up signal (LP-WUS) and a low-power synchronization signal (LP-SS) sent by the sending end. The low-power wake-up signal is used to wake up the main communication module of the receiving end. The low-power synchronization signal is used to provide time reference information and other information for receiving the low-power wake-up signal, for example, for performing radio resource management (RRM) measurement of a serving cell, and can also provide wake-up link management, for example, determining whether to activate or deactivate the LP-WUR and turn off the main receiver (MR) according to the measurement result. The first module is always in an off state when it is not woken up by the second module, and does not send or receive data. When there is downlink data, the second module detects the wake-up signal sent by the sending end, and the wake-up signal contains terminal information of the terminal, and then the second module triggers the first module to switch from the off state to the working state to perform data reception and transmission. The second module can be continuously turned on or discontinuously turned on. When the second module is turned on, it can receive the low-power wake-up signal and the low-power synchronization signal.

[0069] II. Low-power wake-up signal

[0070] In this embodiment, the low-power wake-up signal (LP-WUS) does not belong to the downlink control information DCI, for example, the low-power wake-up signal is not DCI format 2-6 (the DCI format carries wake-up indication information). For example, the waveform or modulation mode of the low-power wake-up signal LP-WUS in this embodiment is: OOK based LP-WUS with overlaid OFDM sequence(s) over OOK symbol. In other words, the low-power signal in this embodiment refers to the LP-WUS with the OFDM sequence superimposed on the OOK symbol or chip.

[0071] In order to reduce the receiving activity of the terminal in the standby state, so that the radio frequency (RF) and baseband (MODEM) modules are truly closed to greatly reduce the power consumption of communication reception, the above low-power receiver can be introduced in the receiving module of the terminal to achieve this. In one embodiment, this near-zero-power receiver does not require complex signal detection (such as amplification, filtering, quantization, etc.) of the RF module and signal processing of the MODEM, but only relies on passive matched filtering and relatively small power signal processing.

[0072] In one embodiment, the low-power wake-up signal is generally some relatively simple on-off keying (OOK) signal, so that the receiver can identify the wake-up announcement through simple energy detection and subsequent possible sequence detection and the like. In another embodiment, the low-power wake-up signal can be an FSK signal, an OFDM signal, or a hybrid signal of OFDM and OOK or FSK. For example, the wake-up signal is an OOK overlaid OFDM signal. In addition, while the terminal turns on the low-power receiver to receive the wake-up signal, the main receiver module can be maintained at a relatively low power consumption level to achieve power saving through receiving the wake-up signal.

[0073] The reception of the low-power wake-up signal can be applied to terminals in the RRC idle or RRC inactive state, and can also be applied to terminals in the RRC connected state, so as to achieve terminal energy saving.

[0074] In addition, in addition to the low-power wake-up signal, there is also a low-power synchronization signal or a low-power measurement signal. They can be collectively understood as low-power signals, and the role of the low-power signals is to save the terminal energy.

[0075] The code point determination method provided by the embodiments of the present application will be described in detail in combination with some embodiments and application scenarios thereof with reference to the accompanying drawings.

[0076] Referring to FIG. 2, the code point determination method provided by the embodiments of the present application includes the following steps:

[0077] In step 201, a terminal determines a first code point associated with the terminal according to first information.

[0078] The first information includes a code point allocated by a core network or the first information includes a number of candidate code points of a low-power wake-up signal (LP-WUS) and at least one of the following:

[0079] The identification information includes: a terminal identification, a group identification determined based on the terminal identification, a group identification allocated by a core network, or a code point allocated by the core network;

[0080] A modulo operation result of the number of the i-th type of code point associated with the terminal based on the terminal identification, the group identification determined based on the terminal identification, or the group identification allocated by the core network;

[0081] The number of the j-th type of code point includes a code point arranged before the i-th type of code point associated with the terminal based on the number of the i-th type of code point;

[0082] The ordering rule of each type of code point is associated with the terminal identification or the group identification determined based on the terminal identification or the group identification allocated by the core network.

[0083] In the case that the number of code points allocated by the core network to the terminal corresponds to the number of bits of the code points carried in the LP-WUS, the first code point associated with the terminal can be directly determined based on the code points allocated by the core network to the terminal. In the case that the number of code points allocated by the core network to the terminal is different from the number of bits of the code points carried in the LP-WUS or the core network does not allocate code points to the terminal, the code point associated with the terminal needs to be determined based on the number of candidate code points of the LP-WUS and the first information.

[0084] For example, in some embodiments, the first code point can be calculated or mapped according to the identification information (such as the terminal identification, the group identification determined based on the terminal identification, the group identification allocated by the core network, or the code point allocated by the core network) and the number of candidate code points of one LP-WUS.

[0085] For example, in some embodiments, the number of the i-th type of code point associated with the terminal can be determined based on the number of candidate code points of one LP-WUS, and the first code point can be determined based on a modulo operation result of the number of the i-th type of code point based on the terminal identification, the group identification determined based on the terminal identification, or the group identification allocated by the core network.

[0086] For example, in some embodiments, the first code point can be calculated based on the number of each type of code point based on the number of candidate code points of one LP-WUS, and the number of the code point arranged before the i-th type of code point.

[0087] For example, in some embodiments, the first code point can be mapped based on the number of each type of code point and the ordering rule of each type of code point based on the number of candidate code points of one LP-WUS.

[0088] It should be noted that the group identifier in the embodiments of the present application can be understood as the group identifier of the LP-WUS group. Optionally, the LP-WUS group (also referred to as subgroup) is a further grouping of terminals associated with one paging occasion (PO).

[0089] The code point associated with the terminal can be one or more, which is related to the mapping type between the code point supported by the terminal and the LP-WUS group.

[0090] In an embodiment, the mapping type between the code point and the LP-WUS group can include: a 1-to-1 mapping type; a 1-to-n mapping type, n being an integer greater than 1; a 1-to-all mapping type. The network side device can configure or protocol agree at least one mapping type in the above mapping types for the terminal.

[0091] Optionally, the code point associated with the terminal can include one or more code points. In this way, the network side device can indicate the terminal to wake up at least one LP-WUS group by carrying the code point in the LP-WUS, thereby improving the flexibility of terminal wake-up.

[0092] Optionally, the network side device configures multiple types of code points, and the ordering rule of each type of code point can include a first layer mapping order and a second layer mapping order, and the first layer mapping order includes any one of a first mapping order and a second mapping order.

[0093] The first mapping order is to complete the mapping between all mapping types and code points within one PO first, and then complete the mapping between the mapping types and the code points in the subsequent POs in the order of the PO index associated with the LP-WUS; and the second mapping order is to complete the mapping between one mapping type and the code points on all associated POs in the order of the PO index associated with the LP-WUS first, and then sequentially perform the mapping between different mapping types and the code points.

[0094] The second layer mapping order is the mapping order between different mapping types.

[0095] Optionally, in the case that the LP-WUS is configured to carry the first indication information, and the code point corresponding to the first indication information carried by the LP-WUS is not specified, the mapping order of the code point further includes a third layer mapping order, and the third layer mapping order includes any one of the following:

[0096] mapping the second indication information carried by the LP-WUS first, and then mapping the first indication information;

[0097] mapping the first indication information first, and then mapping the second indication information carried by the LP-WUS;

[0098] The first indication information is used to indicate information other than LP-WUS group wake-up information, the second indication information is LP-WUS group wake-up indication information used to indicate wake-up of an LP-WUS group, and the first layer mapping sequence and the second layer mapping sequence are mapping sequences associated with the second indication information in the third layer mapping sequence.

[0099] In the embodiments of the present application, the terminal determines a first code point associated with the terminal according to first information. The first information includes a code point allocated by a core network or the first information includes a number of candidate code points of a low-power wake-up signal (LP-WUS) and at least one of the following: identification information including a terminal identifier, a group identifier determined based on the terminal identifier, a group identifier allocated by the core network, a modulo operation result of the terminal identifier, the group identifier determined based on the terminal identifier, or the group identifier allocated by the core network on the number of code points of the ith type, the code points of the ith type being associated with the terminal; a number of code points of the jth type, the code points of the jth type including code points arranged before the code points of the ith type, the code points of the ith type being associated with the terminal; and a sorting rule of each type of code point, the sorting rule being associated with the terminal identifier or the group identifier determined based on the terminal identifier or the group identifier allocated by the core network. The embodiments of the present application clearly define the determination manner of the first code point associated with the terminal, so that the network side device can indicate the terminal to wake up at least one LP-WUS group by carrying the code point in the LP-WUS, thereby improving the flexibility of terminal wake-up and ensuring the accuracy of LP-WUS indication.

[0100] Optionally, in some embodiments, the terminal determines the first code point associated with the terminal according to the first information includes:

[0101] The terminal determines a second code point according to the first information.

[0102] The terminal determines the second information or information converted based on the second information as the first code point, and the second information is determined based on the second code point.

[0103] In the embodiments of the present application, the second information can be directly determined as the first code point, which can simplify the difficulty of determining the first code point and facilitate implementation. The information converted based on the second information can also be determined as the first code point, which can improve the flexibility of determining the first code point.

[0104] Optionally, the second codepoint can be understood or replaced as a reference codepoint or a candidate reference codepoint, where the second codepoint is a reference codepoint in the candidate codepoints. The determining the second information or the information converted based on the second information as the first codepoint can be understood or replaced as determining the second information or the information converted based on the second information as a value or a bit value of the first codepoint.

[0105] Optionally, in some embodiments, the second information includes any of the following:

[0106] The second codepoint;

[0107] The sum of the second codepoint and the offset value;

[0108] The product of the second codepoint and the first value;

[0109] The product of the second codepoint and the first value plus the second value;

[0110] The product of the third value and the first value, the third value being the sum of the second codepoint and the offset value;

[0111] The product of the third value and the first value plus the second value, the third value being the sum of the second codepoint and the offset value;

[0112] The sum of the fourth value and the offset value, the fourth value being the product of the second codepoint and the first value;

[0113] The sum of the fourth value and the offset value and the second value, the fourth value being the product of the second codepoint and the first value;

[0114] Wherein, the first value is a constant or the first value is determined based on a scaling factor F.

[0115] In the embodiments of the present application, the definition of the second information is clarified, which can be a second codepoint or a value processed by the second codepoint, so as to help the terminal better determine the associated first codepoint and improve the LP-WUS detection performance.

[0116] It should be noted that the determination method of the second information can be agreed by the protocol or configured by the network side device, for example, different determination methods can be used for different types of LP WUR.

[0117] For example, in some embodiments, the second codepoint associated with the terminal is: the relative order mapping index value of the terminal in the i-th type of codepoint plus the sum of the number of codepoints of all types before the i-th type of codepoint.

[0118] For example, in some embodiments, the second codepoint associated with the terminal is: the relative mapping order index value of the terminal in the ith type of codepoint plus the sum of the number of all types of codepoints mapped by codepoint mapping before the ith type of codepoint, plus an offset value. Wherein the offset is configured or predefined by the network side device.

[0119] Optionally, if one LP-WUS corresponds to multiple POs, the above-mentioned subgroup ID (including the subgroup ID based on core network allocation and the subgroup ID determined based on UE ID) can be the subgroup ID within one PO, or the subgroup ID determined jointly by multiple POs.

[0120] For example, in some embodiments, wherein the second codepoint associated with the terminal is determined according to the terminal identifier (UE ID) or the subgroup identifier (UE subgroup ID) or the CN allocated ID or the CN allocated subgroup ID or the CN allocated codepoint, and the number of each type of codepoint, and the sorting rule of each codepoint in each type of codepoint.

[0121] Wherein, the sorting rule is related to the size of the UE ID or the subgroup ID.

[0122] Optionally, in some embodiments, the information converted based on the second information includes any of the following:

[0123] L bits obtained by bit encoding Z bits;

[0124] L bits obtained by bit encoding Z bits and rate matching;

[0125] L second bits obtained by adding L-Z padding bits to Z bits;

[0126] L bits obtained by adding L-Z cyclic redundancy check bits to Z bits;

[0127] L bits obtained by adding L-Z 0 or 1 to Z bits in high or low bit;

[0128] Wherein, L is the number of bits of the first codepoint, and the Z bits are the bit combination of 0 and 1 corresponding to the second information.

[0129] In the embodiments of the present application, the bit encoding can include at least one of RM encoding and repetition encoding. The RM encoding can be understood as a linear block code, and the error code resistance is enhanced by adding redundant information in the encoding process.

[0130] It should be understood that the L can be the number of bits actually carried by the network side device in sending the LP-WUS, so that when the candidate code points are configured, Z bits can be configured, and the terminal obtains the first code point of L bits based on the Z bits, so as to reduce the resource overhead of configuration. Therefore, in the embodiments of the present application, smaller configuration signaling overhead can be used to realize the allocation of multiple types of code points corresponding to different numbers of terminals and LP-WUS grouping of terminals, thereby reducing the overhead of configuration signaling. In addition, since the conversion relationship between the second code point and the first code point is determined, it is easy to implement the standard.

[0131] Optionally, in some embodiments, the method further includes:

[0132] The terminal determines the value of Z according to the total number C of all types of candidate code points.

[0133] Optionally, assuming that the total number of candidate code points is C, Z can be equal to ceil log 2(C) information bits. According to one implementation, Z=L, and according to another implementation, Z

[0134] Optionally, in some embodiments, the number of candidate code points includes at least one of the following:

[0135] The number of code points determined according to the terminal identifier or the terminal grouping;

[0136] The number of code points allocated by the core network.

[0137] In the embodiments of the present application, the terminal grouping can be understood as the LP-WUS grouping of the terminal. The number of code points determined according to the terminal identifier or the terminal grouping can include the number of code points determined according to the number of terminal identifiers, or the number of code points determined according to the number of LP-WUS groupings.

[0138] Optionally, in some embodiments, the number of candidate code points of the one low-power wake-up signal LP-WUS includes any of the following:

[0139] Total number of all types of candidate codepoints

[0140] Number of one type of candidate codepoint (Candidate codepoint) X i .

[0141] Optionally, one LP-WUS supports Q types of candidate codepoints, and the number of each type of candidate codepoint is X i , i = 1, 2, ···, Nc, Q is a positive integer.

[0142] Wherein, Nc is agreed by protocol or configured by network side device, or Nc is determined based on Q.

[0143] Optionally, the value of Xi is predefined by standard or configured by network or determined according to predefined rule.

[0144] For example, the network side device configures X1 = 32, X2 = 8 and X3 = 1. It respectively represents that the number of codepoints of the first type (X1) is 32, the number of codepoints of the second type (X2) is 8, and the number of codepoints of the third type (X3) is 1.

[0145] Total number of all types of Candidate codepoint C = X1 + X2 + X3.

[0146] Optionally, the network side device can configure the codepoint of the i-th type as one codepoint corresponding to Ns_i subgroups. For example, the network side device configures the codepoint of the first type as one codepoint corresponding to Ns_1 = 1, that is, the codepoint of the first type corresponds to 1 subgroup; the network side device configures the codepoint of the second type as one codepoint corresponding to Ns_2 = all, that is, the codepoint of the second type corresponds to all subgroups; the network side device configures the codepoint of the third type as one codepoint corresponding to Ns_3 = 2, that is, the codepoint of the second type corresponds to 2 subgroups.

[0147] Optionally, in some embodiments, the codepoint of a specific type is predefined by standard, and the network side device configures the codepoint of other types. For example, one codepoint corresponding to 1 subgroup and one codepoint corresponding to all subgroups are two types of codepoints that are standard predefined and supported. The network side device can additionally configure the type information of one codepoint corresponding to n subgroups, where n is greater than 1 and less than the number of all subgroups.

[0148] wherein the number of codepoints of the ith type can be obtained according to a predefined rule, for example, one codepoint corresponds to waking up n subgroups at the same time, then the number of codepoints is COMBIN(N, n), where N is the total number of subgroups.

[0149] Optionally, the value of the bit number L of the first codepoint can be determined by a protocol, a network-side device, or according to a predefined rule.

[0150] For example, the standard predefines one or more values of L. Optionally, if the standard predefines multiple values of L, one value of L under the current LP-WUS configuration is determined according to a predefined rule.

[0151] Optionally, determining L based on a predefined rule can be understood as: determining L according to the third information, that is, in some embodiments, the method further comprises:

[0152] determining, by the terminal, the bit number L of the first codepoint according to the third information;

[0153] wherein the third information comprises at least one of M and C, M is the number of on-off keying (OOK) symbols within one orthogonal frequency division multiplexing (OFDM) symbol, and C is the total number of candidate codepoints of all types.

[0154] Optionally, in some embodiments, the third information can further comprise a scaling factor F. The scaling factor can be understood as a parameter for mapping the first codepoint, or a parameter for determining the first codepoint.

[0155] For example, L = ceil(log2(C*F));

[0156] For another example, L = ceil(log2(C*F)) + Lp, where Lp is a minimum positive integer such that one LP-WUS with a bit number of L can be mapped to an integer number of OFDM symbols, or Lp is configured by a network-side device.

[0157] For another example, L = ceil(log2(C)).

[0158] Optionally, the scaling factor F described above can be predefined by a standard, configured by a network-side device, or determined according to a predefined rule.

[0159] Optionally, determining F based on a predefined rule can be understood as: determining F according to L and C. That is, in some embodiments, the method further comprises:

[0160] The terminal determines a scaling factor F based on L and C, where C is the total number of all types of candidate codepoints and L is the number of bits of the first codepoint.

[0161] Example 1: F = Floor(2^L / C). Where L is predefined by the standard or configured by the network side device. The scaling factor F can be obtained by L and C.

[0162] Example 2: F is the largest integer less than or equal to Floor(2^L / C) and F is not equal to a specific value, for example, F is not equal to a power of 2 or F is not equal to an even number.

[0163] Example 3: F is the largest integer less than or equal to Floor(2^L / C / A), where A is a network configured parameter.

[0164] Example 4: F is the largest integer less than or equal to Floor(2^L / C / A) and F is not equal to a specific value, for example, F is not equal to a power of 2 or F is not equal to an even number.

[0165] Example 5: F = 1.

[0166] Optionally, in some embodiments, the method further comprises:

[0167] In a case where the terminal detects that the LP-WUS carries the first codepoint associated with the terminal, the terminal monitors a Physical Downlink Control Channel (PDCCH).

[0168] Optionally, the terminal monitoring the PDCCH can be understood or replaced as the terminal monitoring a paging.

[0169] It should be noted that the codepoint associated with the terminal can include one or more, and the terminal needs to monitor multiple codepoints associated with the terminal. When the terminal detects that the LP-WUS carries any one of the codepoints associated with the terminal, the terminal will monitor the paging, otherwise, the terminal does not monitor the paging.

[0170] Alternatively, in some embodiments, when the terminal detects that the LP-WUS carries any one of the codepoints associated with the terminal, the terminal will not monitor the PDCCH, otherwise, the terminal monitors the PDCCH.

[0171] Optionally, in some embodiments, the number of bits L of the first codepoint satisfies that one LP-WUS maps to an integer number of OFDM symbols.

[0172] Where L is an integer multiple of M or L*K is an integer multiple of M, K is a modulation rate or a coding rate, and M is the number of OOK symbols within one OFDM symbol.

[0173] For example, K=K1*K2, where K1 is a parameter of encoding rate, such as Manchester encoding, 1 bit corresponds to 2 OOK symbols after Manchester encoding, then K1=2. K2 is the number of repeated transmission.

[0174] In order to better understand the present application, the following is illustrated by some examples.

[0175] In some embodiments, the network side device can configure multiple types of code points.

[0176] One LP-WUS supports one or more types of Candidate codepoint. The number of each type of Candidate codepoint is X i , i=1, 2…Nc.

[0177] Wherein, the value of X i of different types of code points can be understood as the number of effective subgroups.

[0178] For example, the network side device configures X1=32, X2=8, X3=1. Then, the total number of candidate code points is C=X1+X2+X3=41. X1=32 represents the number of effective subgroups=32, X2=8 represents the number of effective subgroups=8, X3=1 represents the number of effective subgroups=1. The more the number of effective subgroups, the fewer the number of UEs corresponding to the same code point, and the smaller the probability of being mistakenly awakened.

[0179] Optionally, the subgroup based on UE_ID and the code point based on CN allocation can be configured respectively. For example, the subgroup based on UE_ID is configured as X1=32, X2=8, X3=1, and the code point based on CN allocation is configured as X0=20. Alternatively, a set is configured, which is applicable to the subgroup based on UE_ID and the code point based on CN allocation.

[0180] Optionally, the number of code points associated with the terminal includes at least one of the following: the number of X i configured for the subgroup based on UE_ID, and the number of X iThe number of codepoints. For example, if a UE is not configured with codepoints determined based on CN allocation, or, the UE is configured with codepoints determined based on CN allocation, but the cell where the UE is located only supports the method of determining codepoints based on UE_ID, the number of codepoints associated with the UE is equal to X configured for codepoints determined based on UE_ID i The number of codepoints = X1+X2+X 3， Otherwise, the number of codepoints associated with the UE = X0, X0 is the number of codepoints allocated by the CN for the terminal.

[0181] Optionally, the codepoints determined based on UE_ID are arranged in front of the codepoints determined based on CN allocation, for example, the first 41 codepoints are determined based on UE_ID, and the last 20 codepoints are determined based on CN allocation.

[0182] Alternatively, the codepoints determined based on UE_ID are arranged behind the codepoints determined based on CN allocation, for example, the first 20 codepoints are determined based on CN allocation, and the last 20 codepoints are determined based on UE_ID.

[0183] Optionally, in some embodiments, assuming that the total number of codepoints carried by one LP-WUS is C, it can correspond to Z = ceil log 2(C) bits. In some scenarios, Z is not enough to meet the requirements of link performance, such as not enough to achieve the required FAR (Frame Error Rate), more bits are needed to carry the reference codepoint. Assuming that the actual number of bits required is L, it is necessary to indicate any one of the C codepoints through L bits in a predefined manner.

[0184] In order to further improve the link performance / coverage, the L bits can be processed by encoding and repeating, such as Manchester encoding and repeating.

[0185] Optionally, one or more values of L can be predefined by the standard. If the standard defines multiple values of L, the value of L under the current LP-WUS configuration is determined according to the predefined rule. The value of L corresponds to one or more parameters in the combination of M, SCS, and C. M is the number of OOK symbols in one OFDM symbol. SCS is the subcarrier spacing. The UE determines the value of L according to the combination of one or more parameters in the configured M, SCS, and C.

[0186] For example, the value of L is determined jointly according to a scaling factor F and C. The value of L can also be determined according to M.

[0187] Example 1: L = ceil(log2(C*F)).

[0188] Example 2: L = ceil(log2(C*F))+Lp, where Lpis a smallest positive integer such that one LP-WUS with L bits can be mapped to an integer number of OFDM symbols. For example, C = 10, F = 3, M = 4. To make one LP-WUS can be mapped to an integer number of OFDM symbols, ceil(log2(10*3))+Lp = 5+3 = 8, where Lp = 3, L = 8. This LP-WUS is mapped to 8 OOK symbols, i.e., 2 complete OFDM symbols. Here, Lpbits are located at the highest Lp bits of L bits, or Lpbits are located at the lowest Lp bits of L bits.

[0189] Another way of example 2, Lpis configured by the network side device. L = ceil(log2(C*F))+Lp or L = ceil(log2(C*F*Lp)). The network side device can divide the total number of codepoints that L bits can support into multiple codepoint pools for LP-WUSs of different uses by configuring Lp. For example, Lp = 0 or log2(C*F) or ceil(log2(C*F)) are respectively used for LP-WUSs of paging and LP-WUSs of connected discontinuous reception (C-DRX) on duration.

[0190] Optionally, the value of F can be predefined by the standard, or configured by the network side device, or determined according to a predefined rule. For example, if the network side device configures L, F can be determined according to a predefined rule.

[0191] Example 1: F = Floor(2^L / C). Here, L is predefined by the standard or configured by the network side device. The scaling factor F can be obtained by L and C.

[0192] Example 2: F is the largest integer less than or equal to Floor(2^L / C), and F is not equal to a specific value, for example, F is not equal to a power of 2, or F is not equal to an even number.

[0193] In Example 2, to increase the interval of the combination of 0 and 1 bits corresponding to each codepoint, the value of F should avoid the power of 2, or even number. For example, F = 2 will cause the combination of 0 and 1 bits corresponding to each codepoint to only have 1 bit difference.

[0194] Example 3: F is the largest integer less than or equal to Floor(2L / C / A), where A is a parameter configured by the network side device. The network side device can achieve the division of the total number of codepoints supported by L bits into multiple codepoint pools for different uses of LP-WUS by configuring A and configuring Offset. For example, A = 2, Offset = 0 or 2L / A = 2(L-1), respectively for the LP-WUS for paging and the LP-WUS for C-DRX on duration.

[0195] Optionally, in an implementation, L is the same for different receiver types, such as OOK receiver and OFDM receiver. Alternatively, L can be determined (respectively configured or predefined or calculated) respectively for different receiver types. Because the performance of different receivers is different, such as FAR, Minimum Discernible Ratio (MDR), the required number of bits L can be different. Then, the LP-WUS carries L ook bits through OOK symbol, and carries L ofdm bits through overlaid OFDM sequence. Although the lengths of L ook and L ofdm are different, the same information is carried. Similarly, F can be the same or determined respectively for different receiver types.

[0196] Optionally, in some embodiments, the calculation of the first codepoint associated with the terminal can include any of the following:

[0197] Formula 1: the first codepoint corresponding to L bits associated with the terminal = ((UE_ID or UE_subgroup_ID) mod Xi) + sum(X j ,j=0,1,2,…i-1))*G.

[0198] Formula 2: the first codepoint corresponding to L bits associated with the terminal = (UE_ID or UE_subgroup_ID mod X i )+sum(X j ,j=0,1,2,…i-1))*G+Offset1.

[0199] Formula 3: the first codepoint corresponding to L bits associated with the terminal = (((UE_ID or UE_subgroup_ID mod Xi )+sum(X j , j = 0, 1, 2, … i-1) * F + Offset1) * G’.

[0200] Where UE_subgroup_ID identifies the grouping identity of the terminal.

[0201] Offset1 is configured by the network side device or predefined by the standard. The network side device can control the codepoint value by configuring Offset1 to improve performance, such as increasing the spacing of codepoints, reducing inter-cell interference, LP-WUS for different purposes (such as for paging reception and for receiving PDCCH in the On duration of C-DRX), etc. For example, for LP-WUS for different purposes, different codepoint values or L-bit values can be allocated, which can be achieved by configuring offset1. If Offset1 is not configured, Offset1 = 0 or 1. Assuming that Lp bits are located in the lowest Lp bits of L bits, it is equivalent to multiplying 2 on the basis of F Lp .

[0202] G = F, for example, assuming that the number of bits of an LP-WUS is L, and ceil(log2(C*F)) = L, or ceil(log2(C*F))+Lp = L, and Lp bits are located in the highest Lp bits of L bits. Or G = F*2 Lp , for example, assuming that Lp bits are located in the lowest Lp bits of L bits, it is equivalent to multiplying 2 on the basis of F Lp . Or G = 1, or F = 1.

[0203] G’ = 2 Lp , for example, assuming that Lp bits are located in the lowest Lp bits of L bits, or G’ = 1.

[0204] Optionally, different receiver types can use the same parameters or different parameters (respectively configured or predefined or calculated). For example, for OOK receivers, G > 1, for OFDM receivers, G = 1, that is, the codepoint value carried by the overlaid OFDM sequence is not amplified, and the codepoint value sent by the LP-WUS through the OOK symbol is amplified by G times.

[0205] Optionally, if there are both UE_ID based codepoints and CN assigned codepoints, for UE with CN assigned codepoint or for UE with UE_ID based codepoint, the total number of UE_ID based codepoints or the total number of CN assigned codepoints should be added in the above formula 1, 2, 3.

[0206] For example, based on the above formula 3.

[0207] In some examples, for UE with UE_ID based codepoint, the first codepoint corresponding to the L bits associated with the UE = (((UE_ID or UE_subgroup_ID mod X i )+sum(X j ,j=0,1,2,…i-1))*F+Offset1)*G’+C2, where C2 is the total number of CN assigned codepoints. Or, C2 is the total number of CN assigned codepoints+offset 2, offset 2 can be standard predefined or network configured. Offset2 can increase the distance between CN assigned codepoint and UE_ID based codepoint. If Offset2 is not configured, the default value of Offset2 is 0, or 1.

[0208] For UE with CN assigned codepoint, the first codepoint associated with the UE is configured by CN for this UE.

[0209] In some examples, for UE with UE_ID based codepoint, the first codepoint corresponding to the L bits associated with the UE = (((UE_ID or UE_subgroup_ID mod X i )+sum(X j ,j=0,1,2,…i-1))*F+Offset1)*G’.

[0210] For UE with CN assigned codepoint, the first codepoint associated with the UE = C1+CN configured codepoint value for this UE. C1 is the maximum value (or the maximum value+offset2) of UE_ID based codepoint, offset 2 can be standard predefined or network configured. For example, C1=sum(X i )*G, i=1,2,…,Nc.

[0211] Alternatively, for a UE associated with a codepoint based on CN allocation, the value of the first codepoint associated with the UE is any one of the following:

[0212] (C1+CN configured codepoint value of this UE)*G;

[0213] (C1+CN configured codepoint value of this UE)*G+1;

[0214] (C1+CN configured codepoint value of this UE)*G';

[0215] (C1+CN configured codepoint value of this UE)*G+offset1;

[0216] ((C1+CN configured codepoint value of this UE)*F+offset1)*G'.

[0217] Where C1 is the maximum value (or maximum value+1) of the codepoint determined based on UE_ID.

[0218] Optionally, in some embodiments, the network side device can configure multiple types of codepoints, and the number of each type of codepoint is X i The following describes how the terminal determines the first codepoint associated with itself and how to determine the value of the L bits corresponding to the codepoint.

[0219] Suppose X1=32, X2=8 and X3=1 are codepoints determined based on UE_ID, and the network node configures X0=32, which is the codepoint allocated by CN.

[0220] Optionally, in some embodiments, the first codepoint associated with the UE is calculated according to UE_ID or UE_subgroup_ID. UE_subgroup_ID can be calculated according to UE_ID or allocated by CN. If the X0 codepoints allocated by CN are in the front, and the codepoints determined based on UE_ID or UE_subgroup_ID are in the back.

[0221] In one example, the second codepoint associated with a UE (a UE whose codepoint is determined based on UE_ID or UE_subgroup_ID) is any one of the following:

[0222] (UE_ID or UE_subgroup_ID mod X i )+sum(Xj j = 1, 2,... i-1) + C2;

[0223] (UE_ID or UE_subgroup_ID mod X i )+sum(X j j = 1, 2,... i-1) + C2+offset3;

[0224] Where C2=X0 is the total number of codepoints allocated by CN, offset3 is configured by network side device.

[0225] In one example, the second codepoint associated with one UE (the UE whose codepoint is allocated by CN) is configured by CN for the UE.

[0226] Optionally, in some embodiments, the first codepoint associated is calculated according to UE_ID or UE_subgroup_ID. UE_subgroup_ID can be calculated according to UE_ID, or allocated by CN. If X0 codepoints allocated by CN are in the back, the codepoint determined according to UE_ID or UE_subgroup_ID is in the front.

[0227] In one example, the second codepoint associated with one UE (the UE whose codepoint is determined according to UE_ID or UE_subgroup_ID) is any of the following:

[0228] (UE_ID or UE_subgroup_ID mod X i )+sum(X j j = 1, 2,... i-1);

[0229] (UE_ID or UE_subgroup_ID mod X i )+sum(X j j = 1, 2,... i-1) + offset3.

[0230] In one example, the second codepoint associated with one UE (the UE whose codepoint is allocated by CN) is C1+ the codepoint value available for the UE configured by CN, where C1 is the total number of codepoints determined according to UE_ID or UE_subgroup_ID, C1=X1+X2+X3. Offset3 is configured by network side device.

[0231] Optionally, if one LP-WUS corresponds to multiple POs, subgroup_ID (including grouping identification determined based on CN allocation and grouping identification determined based on UE_ID) can be subgroup_ID within one PO, or subgroup_ID determined jointly by multiple POs.

[0232] Optionally, the network side device can also configure offset 4 (or gap) of codepoint determined based on CN allocation and codepoint determined based on UE_ID. Then, the value of codepoint arranged in the back is offset 4 or offset 4+offset 3 after the total number of codepoint arranged in the front.

[0233] Optionally, assuming the total number of candidate codepoints is C, it can correspond to Z = ceil log 2(C) information bits. According to one implementation, Z = L, and according to another implementation, Z < L. For example, for an OFDM receiver, Z = L, that is, the bits carried by the overlaid OFDM sequence are information bits Z. For an OOK receiver, Z < L, that is, the bits carried by the OOK symbol are L bits containing redundancy. Alternatively, for an OOK receiver and an OFDM receiver, Z < L, and L is the same. Alternatively, Z < L, but L is different, for example, L_ook > L_ofdm > Z.

[0234] If Z < L, the Z bits can be encoded (excluding line code, e.g. Manchester encoding), e.g. RM encoding, repetition encoding, and rate matched to L bits. Or, L-Z padding bits are added to the Z bits, or L-Z CRC bits are added to the Z bits. After generating L bits, Manchester encoding can be performed again. Or, a second codepoint (reference codepoint value) is scaled to a codepoint value (or value of L bits) in L bits. For example, (reference codepoint value*G) or (reference codepoint value*G)+1 or ((reference codepoint value+Offset1)*G) or (( (reference codepoint value+Offset 1)*G)+1) or (( (reference codepoint value+Offset 1)*G)+1) or (reference codepoint value*G)+Offset1 or (reference codepoint value*G)+Offset1+1 is converted to a binary number, which is Z’ bits, and L-Z’ zeros are added to the high or low bits to convert to L bits.

[0235] where the scaling factor is F, F is configured by the network side device or determined according to a predefined rule (e.g. determined according to the configured L). G=F or G=F*2 Lp . Assuming that the Lp bits are located in the lowest Lp bits of the L bits, or G’=2 Lp . Assuming that the Lp bits are located in the lowest Lp bits of the L bits, where Lp is such that an LP-WUS with L bits can be mapped to an integer number of OFDM symbols with a smallest positive integer. For example, the total number of candidate codepoints C=10 is configured by the network side device, F=3, M=4. In order to make an LP-WUS can be mapped to an integer number of OFDM symbols, ceil(log2(10*3))+Lp=5+3=8, where Lp=3, L=8. This LP-WUS is mapped to 8 OOK symbols, i.e. 2 complete OFDM symbols. Offset1 can be configured by the network side device or predefined by the standard.

[0236] The scheme of the present application is applicable to a paging mechanism based on an LP-WUS, for example, a UE receives a codepoint indicating to wake up itself in an LP-WUS, and then the UE attempts to receive a paging message in the nearest PO meeting a delay requirement. The scheme of the present application is also applicable to a PDCCH monitoring mechanism of an LP-WUS, for example, a UE receives a codepoint indicating to wake up itself in an LP-WUS when in an RRC connected state, and then the UE attempts to receive a PDCCH in the nearest PDCCH MO meeting a delay requirement or in the nearest DRX On duration meeting a delay requirement.

[0237] As mentioned in the above embodiments, for different application scenarios of an LP-WUS, for example, attempting to receive a paging or attempting to receive a PDCCH in a DRX On duration, the used method can be different or the used method is the same but parameters are different (for example, an offset can be different).

[0238] The scheme of the present application is applicable to an OOK detection low-power receiver and also applicable to an OFDM sequence detection low-power receiver. For different receivers, the used method can be different.

[0239] Referring to FIG. 3, the present embodiment further provides a codepoint determination method, as shown in FIG. 3, the codepoint determination method comprises:

[0240] In step 301, a network side device determines a first codepoint associated with a terminal according to first information;
