[0001] The present application relates to the field of wireless technology, and in particular to a configuration method, device, terminal and storage medium for signal or channel detection. Background Art

[0002] In the paging mechanism of the New Radio (NR), the terminal needs to detect paging at each paging occasion (PO, Paging Occasion). However, since the terminal does not have real business at each PO, there will be a large number of useless paging detections, resulting in energy waste of the terminal. In the related art, the Paging Early Indication (PEI) is used to indicate whether the terminal needs to detect the paging PDCCH and the corresponding PDSCH. In the related art, a terminal in an idle or inactive state cannot receive terminal-specific configuration information and can only receive broadcast configuration information from the network side. Therefore, the terminal needs to determine the terminal-specific PEI detection parameters based on the broadcast configuration information on the network side. Summary of the Invention

[0043] In the New Radio (NR), the terminal uses discontinuous reception (DRX) to detect paging messages. The terminal detects a PO in each DRX cycle. Here, a PO is a group of physical downlink control channel (PDCCH) detection opportunities, which can include multiple time slots. In actual applications, the PDCCH indicating the paging message transmitted on the PO (hereinafter referred to as the paging PDCCH) will be scrambled using the paging radio network temporary identifier (P-RNTI). A PF may contain one or more POs, and the PF satisfies the formula (SFN+PF_offset)mod T=(T div N)*(UE_ID modN). In addition, the terminal obtains the PO by searching the index i_s: i_s = floor (UE_ID / N) mod Ns, where SFN represents the system frame number (System Frame Number), PF_offset represents the offset value used to calculate the PF, T represents the DRX cycle of the terminal, N represents the number of PFs included in the T time, Ns is the number of POs included in a PF, and UE_ID is equal to 5G-S-TMSI mod1024, where S-TMSI is SAE Temporary Mobile Station Identifier, and 5G-S-TMSI is a 48-bit bit string defined in TS23.501. If the terminal does not have a 5G-S-TMSI, then UE_ID is equal to 0. In the above formula, N and Ns are configured through Radio Resource Control (RRC).

[0044] Based on such a NR paging design, terminals with the same or different UE_ID will be calculated to the same PO position. Therefore, after detecting the paging PDCCH, the terminal needs to further read the PagingRecordList in the physical downlink shared channel (PDSCH) scheduled by the paging PDCCH to determine whether the PagingUE-Identity in the PagingRecordList matches the terminal's 5G-S-TMSI or full I-RNTI, so as to determine whether the terminal is paged. In other words, the terminal also needs to detect the PDSCH scheduled by the PDCCH transmitted on the PO to determine whether there is actually a paging message. In actual application, even if only one terminal among the multiple terminals corresponding to a PO needs to be paged, all terminals corresponding to the PO need to detect the paging PDCCH and the corresponding PDSCH. Such a detection action is meaningless for terminals that do not need to be paged, and will cause terminals in idle or inactive states to consume too much energy on invalid detection behaviors.

[0045] In order to avoid the above problems, in the related art, a paging early indication (PEI, Paging Early Indication) is used to indicate whether the terminal needs to detect the paging PDCCH and the corresponding PDSCH. At present, NR can be configured with multiple paging parameters N and Ns, where N represents the number of PFs included in the T time, and Ns is the number of POs included in a PF. In scenarios with high paging density, for example, at the maximum density (ontT, Ns=4), there will be a PO every 2.5ms. If the PEI and PO are mapped one to one, then excessive paging density will cause the PEI overhead to increase. Considering that PEI, paging PDCCH and corresponding PDSCH, as well as synchronization signal blocks (SSB, Synchronization Signal Block), system messages, etc. are all transmitted in the initial downlink bandwidth (BWP, Band Width Part), this will cause the initial downlink BWP resources to be tight. Therefore, in scenarios with high paging density, one PEI is usually designed to correspond to multiple POs, that is, one PEI indicates whether multiple POs are awake. In the scenario of low paging density, PEI will not generate too much overhead. In order to further improve the energy-saving gain of terminal paging detection, the terminals of a PO can be grouped, and a PEI can indicate whether multiple terminal groups are awake. In this way, since the number of terminals in the terminal group is less than the number of terminals in a PO, the probability of the terminal being awakened will be further reduced, and the energy-saving gain will be improved.

[0046] Therefore, from the perspective of the network side, there is a mapping relationship between PEI and PO, as well as a mapping relationship between PEI and terminal grouping; from the perspective of the terminal, a terminal will only correspond to one PEI, but this PEI is shared with other terminals. Since the terminal can only receive public broadcast configuration information in the idle state or inactive state, and cannot receive terminal-specific configuration information, the design of PEI needs to consider how to allow the terminal in the idle state or inactive state to determine the corresponding PEI. For example, if PEI is a PDCCH, how does the terminal know the position of its corresponding bit in the downlink control information (DCI) format; if PEI is a reference signal, how does the terminal know the sequence parameters corresponding to itself, such as the sequence index or the cyclic shift index.

[0047] The base station cannot use dedicated configuration for the terminal. Taking into account the different mapping relationships between N, Ns, PEI and PO, and the number of terminal groups, it is necessary to design an implicit PEI determination and detection method so that different terminals can determine their own PEI detection parameters based solely on the public configuration parameters in the System Information Block (SIB).

[0048] Based on this, in an embodiment of the present application, based on the paging configuration parameters of the first terminal, the first terminal determines the first detection parameter of the first signal or the first channel used to indicate whether the terminal detects paging. In the above scheme, the terminal determines the first detection parameter of the first signal or the first channel based on its own paging configuration parameters, rather than determining the first detection parameter of the first signal or the first channel through the terminal-specific configuration information sent down by the network side. In this way, the configuration of the first detection parameter of the first signal or the first channel does not bring additional signaling overhead, and the terminal can also determine the first detection parameter of the first signal or the first channel when it is in an idle state or an inactive state, perform detection of the first signal or the first channel, and save terminal energy.

[0049] The present application will be described in further detail below with reference to the accompanying drawings and embodiments.

[0050] The embodiment of the present application provides a method for detecting a signal or a channel, characterized in that it is applied to a first terminal, such as Figure 1 As shown, the method includes:

[0051] Step 101: Determine a first detection parameter of a first signal or a first channel of the first terminal based on a paging configuration parameter of the first terminal.

[0052] The first signal or the first channel is used to indicate whether the terminal detects paging.

[0053] In actual application, the first signal or the first channel can be understood as PEI, or other physical channels or physical signals for indicating whether the terminal detects paging, and the first detection parameter is a parameter for detecting PEI.

[0054] In one embodiment, the first detection parameter includes at least one of the following:

[0055] bit position;

[0056] Sequence cyclic shift;

[0057] Sequence index;

[0058] Detect location.

[0059] Here, based on the paging configuration parameters of the first terminal, a parameter for instructing the first terminal to detect the first signal or the first channel can be determined. If the first signal or the first channel is a PDCCH, then the first detection parameter indicates the bit position of the first terminal detecting the corresponding paging indication information of the first terminal on the PDCCH; if the first signal or the first channel is a sequence, then the first detection parameter indicates the sequence cyclic shift or sequence index of the sequence corresponding to the first terminal; if the first signal or the first channel is multiple PDCCHs or multiple sequences, and one PDCCH or sequence corresponds to one PO or one terminal group, then the first detection parameter indicates the first terminal to detect the corresponding PDCCH or sequence at the corresponding detection position.

[0060] In one embodiment, the first detection parameter represents a parameter determined based on at least a first index of the first terminal; the first index represents an index of the PO of the terminal.

[0061] Here, the first detection parameter may represent a parameter determined based on at least the index i_s of the PO of the first terminal.

[0062] In actual applications, there is a scenario where the transmission period of the first signal or a first channel is the same as the transmission period or time interval of the PF. In this scenario:

[0063] 1. If a first signal or a first channel corresponds to one or more POs, that is, a first signal or a first channel is used to indicate whether a terminal of a PO or multiple POs needs to detect paging, the first detection parameter of the first terminal is represented by the first index.

[0064] In this case, the correspondence between i_s and the parameters used to detect the first signal or the first channel is predefined. If the first signal or the first channel is a PDCCH, i_s=0 corresponds to the first bit, i_s=1 corresponds to the second bit, and the index of the first terminal is i_s=0, then the first detection parameter indicates that the first terminal detects the first bit of the PDCCH; if the first signal or the first channel is a sequence, i_s=0 corresponds to cyclic shift #1, i_s=1 corresponds to cyclic shift #2, and the index of the first terminal is i_s=0, then the first detection parameter indicates that the first terminal detects the sequence of cyclic shift #1; if the first signal or the first channel is multiple PDCCHs or sequences, one PDCCH or sequence corresponds to one PO, i_s=0 corresponds to PDCCH or sequence detection position #0, i_s=1 corresponds to PDCCH or sequence detection position #1, and the index of the first terminal is i_s=0, then the first detection parameter indicates that the first terminal detects the corresponding PDCCH or sequence at PDCCH or sequence detection position #0.

[0065] Combine Figure 2 Specific examples, such as Figure 2 As shown, the transmission period of the PF is T1, and the transmission period of the first signal or the first channel, such as PEI, is T2, where T1 = T2. A PF includes PO 1 and PO 2, and one first signal or first channel (PEI) corresponds to one PO. In this case, the detection parameter of the first signal or the first channel of the first terminal is determined based on the first index of the first terminal, thereby determining the detection position of the first signal or the first channel.

[0066] Combine Figure 3 Specific examples, such as Figure 3 As shown, the transmission period of the PF is T1, and the transmission period of the first signal or the first channel, such as PEI, is T2, where T1=T2. A PF includes PO 1 and PO 2, and a first signal or a first channel (PEI) corresponds to two POs. In this case, the detection parameter of the first signal or the first channel of the first terminal is determined based on the first index of the first terminal, thereby determining at least one of the following detection parameters of the first signal or the first channel: bit position, sequence cyclic shift, sequence index, and detection position.

[0067] 2. If a first signal or a first channel corresponds to one or more terminal groups on one or more POs, that is, a first signal or a first channel is used to carry or indicate whether one or more terminal groups detect paging information, the first detection parameter of the first terminal is determined based on the first index, the second index and the first quantity.

[0068] The second index represents the index of the first terminal in the corresponding terminal group; the first number represents the number of terminal groups, and the first index represents the index of the terminal's PO.

[0069] Taking PEI as an example, here, a first signal or a first channel (PEI) is used to carry or indicate whether one or more terminal groups detect paging. In this case, illustratively, the first detection parameter can be determined based on i_s*M+m, where M represents the number of terminal groups in a PO, m represents the index of the first terminal in the corresponding terminal group, and i_s represents the index of the terminal's PO. Specifically, the correspondence between i_s*M+m and the parameters used to detect the first signal or the first channel is predefined. If the first signal or the first channel is a PDCCH, the index i_s of the first terminal is 0, then the first terminal detects the bit corresponding to or determined by 0*M+m in the PDCCH; if the first signal or the first channel is a sequence, the index i_s of the first terminal is 0, then the first terminal detects the cyclic shift or sequence index corresponding to or determined by 0*M+m; if the first signal or the first channel is multiple PDCCHs or sequences, the index i_s of the first terminal is 0, then the first terminal detects the PDCCH or sequence at the PDCCH or sequence detection position corresponding to or determined by 0*M+m.

[0070] Combine Figure 2 Specific examples, such as Figure 2 As shown, the transmission period of the PF is T1, and the transmission period of the first signal or the first channel, such as PEI, is T2, where T1 = T2. A PF includes PO 1 and PO 2, and one first signal or first channel (PEI) corresponds to one PO. In this case, the detection parameter of the first terminal for the PEI is determined based on i_s*M+m, thereby determining at least one of the following detection parameters of the first signal or the first channel: bit position, sequence cyclic shift, sequence index, and detection position.

[0071] Combine Figure 3 Specific examples, such as Figure 3 As shown, the transmission period of PF is T1, the transmission period of PEI is T2, and T1=T2. A PF includes PO 1 and PO 2, and a PEI corresponds to two POs. In this case, the detection parameter of the first terminal for PEI is determined based on i_s*M+m, thereby determining at least one of the following detection parameters of the first signal or the first channel: bit position, sequence cyclic shift, sequence index, and detection position.

[0072] In actual applications, there may be a scenario where the transmission period of the first signal or the first channel is different from the transmission period of the PF. In this scenario:

[0073] 1. If a first signal or a first channel corresponds to one or more POs, that is, a first signal or a first channel is used to indicate whether the terminal of one or more POs needs to detect paging, the first detection parameter of the first terminal is determined based on the first index and the first value.

[0074] The first value represents a value determined by the system frame number of the PF, a first time length and a second time length, the first time length represents the time interval between adjacent first signals or adjacent first channels; the second time length represents the time interval between adjacent PFs.

[0075] In one embodiment, the first numerical value is represented by the modulus of the first ratio to the second ratio; wherein the first ratio is represented by the ratio of the system frame number of the PF to the second time length; and the second ratio is represented by the ratio of the first time length to the second time length.

[0076] Taking PEI as an example, the first signal or the first channel has a one-to-one mapping relationship with the PO, and one first signal or one first channel corresponds to one PO. In this case, illustratively, the first detection parameter can be determined based on (SFN / T1 mod K)*Ns+i_s, where SFN represents the system frame number of the PF; T1 represents the second time length, that is, the time interval between two adjacent PFs, which can also be understood as the transmission period of the PF; K represents the ratio of the first time length to the second time length, where the first time length represents the time interval between adjacent first signals or adjacent first channels, which can also be understood as the transmission period of the first signal or the first channel. Specifically, a correspondence between (SFN / T1 mod K)*Ns+0 and parameters used to detect the first signal or the first channel is predefined. If the first signal or the first channel is a PDCCH, the index i_s of the first terminal is 0, then the first terminal detects the bit corresponding to (SFN / T1 mod K)*Ns+0 in the PDCCH; if the first signal or the first channel is a sequence, the index i_s of the first terminal is 0, then the first terminal detects the sequence corresponding to the cyclic shift of (SFN / T1 mod K)*Ns+0; if the first signal or the first channel is multiple PDCCHs or multiple sequences, the index i_s of the first terminal is 0, then the first terminal detects the corresponding PDCCH or sequence at the PDCCH or sequence detection position corresponding to (SFN / T1 mod K)*Ns+0.

[0077] Combine Figure 4 Specific examples, such as Figure 4As shown, the transmission period of the PF is T1, and the transmission period of the first signal or the first channel (PEI) is T2, where T2 = K*T1, where K represents an integer greater than 1. A PF contains PO 1 and PO 2, and one PEI corresponds to one PO. In this case, the detection parameters of the first terminal for the first signal or the first channel (PEI) are determined based on (SFN / T1 mod K)*Ns+i_s. Specifically, Ns=2, T=32 radio frames, that is, T=320ms, and N=half T, that is, N=16. Then T1=2 radio frames, that is, T1=20ms. Assuming T2=40ms, then K=2, the SFN of PF1=0, and the SFN of PF2=2. Then, when the value determined by the first terminal based on (SFN / T1 mod K)*Ns+i_s is 0, the terminal detects the PDCCH at the PDCCH detection position corresponding to index 0. Similarly, when the value determined by the first terminal based on (SFN / T1 mod K)*Ns+i_s is 1, the terminal detects the PDCCH at the PDCCH detection position corresponding to terminal index 1. When the value determined by the first terminal based on (SFN / T1 mod K)*Ns+i_s is 2, the terminal detects the PDCCH at the PDCCH detection position corresponding to index 2. When the value determined by the first terminal based on (SFN / T1 mod K)*Ns+i_s is 3, the terminal detects the PDCCH at the PDCCH detection position corresponding to index 3.

[0078] Combine Figure 5 Specific examples, such as Figure 5As shown, the transmission period of the PF is T1, and the transmission period of the first signal or the first channel (PEI) is T2, T2 = K * T1, where K represents an integer greater than 1. A PF contains PO 1 and PO 2, and a PEI corresponds to multiple POs. In this case, the detection parameters of the first terminal for the first signal or the first channel (PEI) are determined based on (SFN / T1 mod K) * Ns + i_s. Specifically, Ns = 2, T = 32 radio frames, that is, T = 320ms, N = half T, that is, N = 16. Then T1 = 2 radio frames, that is, T1 = 20ms. Assuming T2 = 40ms, then K = 2, SFN of PF1 = 0, SFN of PF2 = 2, then when the value determined by the first terminal based on (SFN / T1 mod K) * Ns + i_s is 0, the terminal detects the bit of index 0 in the PDCCH, or the sequence corresponding to the cyclic shift corresponding to index 0. Similarly, when the value determined by the first terminal based on (SFN / T1 mod K)*Ns+i_s is 1, the terminal detects the bit of index 1 in the PDCCH, or the sequence corresponding to the cyclic shift corresponding to index 1. When the value determined by the first terminal based on (SFN / T1mod K)*Ns+i_s is 2, the terminal detects the bit of index 2 in the PDCCH, or the sequence corresponding to the cyclic shift corresponding to index 2. When the value determined by the first terminal based on (SFN / T1 mod K)*Ns+i_s is 3, the terminal detects the bit of index 3 in the PDCCH, or the sequence corresponding to the cyclic shift corresponding to index 3. 2. If a first signal or a first channel corresponds to one or more terminal groups on one or more POs, that is, a first signal or a first channel is used to carry or indicate information on whether one or more terminal groups detect paging, the first detection parameter of the first terminal is determined based on the first index, the first value, the second index and the first quantity.

[0079] Among them, the first numerical value represents a numerical value determined by the system frame number, the first time length and the second time length of the paging frame PF; the second index represents the index of the first terminal in the corresponding terminal group; the first quantity represents the number of terminal groups; the first time length represents the sending period of the signal or channel or the time interval between adjacent signals or channels; the second time length represents the time interval between adjacent PFs.

[0080] In one embodiment, the first numerical value is represented by the modulus of the first ratio to the second ratio; wherein the first ratio is represented by the ratio of the system frame number of the PF to the second time length; and the second ratio is represented by the ratio of the first time length to the second time length.

[0081] In one embodiment, the method further comprises:

[0082] The second ratio or the first time length configured by the network side through a system message is received.

[0083] Taking PEI as an example, here, a first signal or a first channel (PEI) is used to carry or indicate whether one or more terminal groups detect paging information. In this case, illustratively, the first detection parameter can be determined based on [(SFN / T1 mod K)*Ns+i_s]*M+m, where SFN represents the system frame number of PF; T1 represents the second time length, that is, the time interval between two adjacent PFs, which can also be understood as the transmission period of PF; K represents the ratio of the first time length to the second time length, where the first time length represents the time interval between adjacent first signals or adjacent first channels, which can also be understood as the transmission period of the first signal or the first channel, M represents the number of terminal groups in a PO, and m represents the index of the first terminal in the corresponding terminal group. Specifically, a correspondence between [(SFN / T1 mod K)*Ns+i_s]*M+m and parameters used to detect the first signal or the first channel is predefined. If the first signal or the first channel is a PDCCH, and the index i_s of the first terminal is 0, then the first terminal detects the PDCCH at the bit corresponding to [(SFN / T1mod K)*Ns+0]*M+m; if the first signal or the first channel is a sequence, and the index i_s of the first terminal is 0, then the first terminal detects the cyclically shifted sequence corresponding to [(SFN / T1 mod K)*Ns+0]*M+m; if the first signal or the first channel is multiple PDCCHs or sequences, one PDCCH or sequence corresponds to one PO, and the index i_s of the first terminal is 0, then the first terminal detects the corresponding PDCCH or sequence at the PDCCH or sequence detection position corresponding to [(SFN / T1 mod K)*Ns+0]*M+m.

[0084] Combine Figure 4 Specific examples, such as Figure 4 As shown, the transmission period of PF is T1, the transmission period of PEI is T2, T2=K*T1, where K represents an integer greater than 1. One PF includes PO 1 and PO2, and one PEI corresponds to one PO. In this case, the detection parameter of the first signal or the first channel corresponding to the first terminal is determined based on [(SFN / T1 mod K)*Ns+i_s]*M+m.

[0085] Combine Figure 5 Specific examples, such as Figure 5As shown, the transmission period of PF is T1, the transmission period of PEI is T2, T2=K*T1, where K represents an integer greater than 1. One PF includes PO 1 and PO2, and one PEI corresponds to four POs on two PFs. In this case, the detection parameter of the first signal or the first channel corresponding to the first terminal is determined based on [(SFN / T1 mod K)*Ns+i_s]*M+m.

[0086] In an embodiment of the present application, based on the paging configuration parameters of the first terminal, the first terminal determines the first detection parameter of the first signal or the first channel used to indicate whether the terminal detects paging. In the above scheme, the terminal determines the first detection parameter of the first signal or the first channel based on its own paging configuration parameters, rather than determining the first detection parameter of the first signal or the first channel through the terminal-specific configuration information sent down by the network side. In this way, the configuration of the first detection parameter of the first signal or the first channel no longer requires any terminal-specific configuration information, does not bring additional signaling overhead, and the terminal can also determine the first detection parameter of the first signal or the first channel when it is in an idle state or an inactive state, thereby saving terminal energy.

[0087] In order to implement the method of the embodiment of the present application, the embodiment of the present application further provides a signal or channel detection device, which is set on the first terminal, such as Figure 6 As shown, the device includes:

[0089] The first signal or the first channel is used to indicate whether the terminal detects paging.

[0090] In one embodiment, the first detection parameter includes at least one of the following:

[0091] bit position;

[0092] Sequence cyclic shift;

[0093] Sequence index;
