Embodiments for Carrying Out the Invention

[0013] In the new radio (NR), the terminal detects paging messages in a discontinuous reception (DRX) manner. The terminal detects one paging occasion (PO) within each DRX cycle, where one PO is a set of Physical Downlink Control Channel ( PDCCH , PDCCH, Physical Downlink Control Channel) detection opportunities and may include multiple slots. In actual application, the PDCCH (hereinafter referred to as paging PDCCH) that indicates the paging message transmitted in the PO is scrambled using the paging radio network temporary identifier (P-RNTI). One paging frame (PF) may include one or more POs, and the PF satisfies the formula (SFN + PF_offset) mod T = (T div N) * (UE_ID mod N). Also, the terminal searches through the index i_s to obtain the PO where i_s = floor(UE_ID / N) mod Ns, where SFN characterizes the system frame number, PF_offset characterizes the offset value for calculating the PF, T characterizes the DRX cycle of the terminal, N characterizes the number of PFs included within the T time, Ns is the number of POs included within one PF, UE_ID is equal to 5G-S-TMSI mod 1024, where S-TMSI is the SAE Temporary Mobile Station Identifier, 5G-S-TMSI is a bit string with the bit length defined in TS 23.501, and when the terminal does not have 5G-S-TMSI, UE_ID is equal to 0. In the above formula, N and Ns are set via the radio resource control (RRC).

[0014] When based on such an NR paging design, terminals with the same or different UE_IDs are calculated at 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, and determine whether the PagingUE-Identity in the PagingRecordList matches the 5G-S-TMSI or full I-RNTI of the terminal, so as to determine whether the terminal is paged. In other words, the terminal needs to detect the PDSCH scheduled by the PDCCH uploaded by the PO, otherwise it cannot determine whether the paging message really exists. In actual adaptation, even if only one of the multiple terminals corresponding to one PO needs to be paged, all terminals corresponding to the PO need to detect the paging PDCCH and the corresponding PDSCH. Such a detection operation is meaningless for terminals that do not need to be paged, and terminals in the idle state or non-active state will consume excessive energy due to invalid detection operations.

[0015] To avoid the above problems, in related technologies, it is determined by Paging Early Indication ( PEI , Paging Early Indication) whether the terminal needs to detect the paging PDCCH and the corresponding PDSCH. Currently, NR can set multiple paging parameters N and Ns , N characterizes the number of PFs included in the T time, and Ns is the number of POs included in one PF. In the case of a high paging density, for example, at the maximum density (ontT, Ns = 4), with one PO every 2.5 ms and a one-to-one mapping relationship between the PEI and the PO, an overly high paging density causes an increase in the overhead of the PEI. Considering that the PEI, the paging PDCCH, the corresponding PDSCH, the synchronization signal block (SSB), and the system message are all transmitted in the initial downlink bandwidth part (BWP), this causes a shortage of initial downlink BWP resources. Therefore, usually, in a high paging density scenario, one PEI can be designed to correspond to multiple POs, that is, one PEI indicates whether multiple POs are woken up. In a low paging density scenario, the PEI does not generate too much overhead. To further improve the energy-saving gain of paging detection at the terminal, terminal grouping can be performed for the terminals of one PO. One PEI respectively indicates whether multiple terminal groups are woken up. Since the number of terminals in the terminal group is smaller than the number of terminals in one PO, the probability that the terminal is woken up further decreases, so the energy-saving gain is improved.

[0016] Therefore, from the perspective of the network side, there are mapping relationships between the PEI and the PO, and between the PEI and the terminal group. From the perspective of the terminal, one terminal corresponds to only 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 the non-active state and cannot receive terminal-specific configuration information, the design of the PEI must consider the problem of how to determine the corresponding PEI for a terminal in the idle state or the non-active state. For example, when the PEI is the PDCCH, the terminal needs to consider how to determine the position of the bit corresponding to itself in the downlink control information (DCI) format. When the PEI is a reference signal, the terminal needs to consider how to determine the sequence parameters corresponding to itself, such as the index of the sequence or the index of the cyclic shift.

[0017] The base station cannot configure the terminal using dedicated configurations. At the same time, considering different values of N, Ns, the mapping relationship between the PEI and the PO, and the number of terminal groups, it is necessary to design an implicit method for determining and detecting the PEI so that different terminals can detect their own PEI detection parameters using only the public configuration parameters in the system information block (SIB).

[0018] Based on this, in the embodiments of the present application, based on the paging setting parameters of the first terminal, the first terminal determines the first detection parameter of the first signal or the first channel for instructing the terminal whether to detect paging. In the above solution, the terminal determines the first detection parameter of the first signal or the first channel based on its own paging setting parameters, rather than the terminal-specific setting information sent by the network side. In this way, the setting 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 the idle state or the non-active state, detect the first signal or the first channel, and perform energy saving for the terminal.

[0019] Hereinafter, the present application will be described in more detail in combination with the drawings and embodiments.

[0020] The embodiments of the present application provide a method for detecting a signal or a channel applied to a first terminal. As shown in FIG. 1, the method includes the following step 101.

[0021] Step 101: Based on the paging setting parameters of the first terminal, determine the first detection parameter of the first signal or the first channel of the first terminal.

[0022] Here, the first signal or the first channel indicates whether the terminal detects paging.

[0023] In actual adaptation, the first signal or the first channel may be understood as the PEI, or other physical channels or physical signals that indicate whether the terminal detects paging. The first detection parameter is the parameter for detecting the PEI.

[0024] In one embodiment, the first detection parameter includes at least one of a bit position, a sequence cyclic shift, a sequence index, and a detection position.

[0025] Here, it is necessary to determine a parameter for instructing the first terminal to detect a first signal or a first channel based on the paging setting parameter of the first terminal. When the first signal or the first channel is one PDCCH, the first detection parameter indicates that the first terminal detects the bit position of its own paging indication information in the PDCCH. When the first signal or the first channel is a sequence, the first detection parameter represents the sequence cyclic shift or sequence index of the sequence corresponding to the first terminal. When the first signal or the first channel is a plurality of PDCCHs or a plurality of sequences, one PDCCH or one sequence corresponds to one PO or one terminal group. Accordingly, the first detection parameter instructs the first terminal to detect the corresponding PDCCH or sequence at the corresponding detection position.

[0026] In one embodiment, the first detection parameter characterizes a parameter determined based at least on a first index of the first terminal, and the first index characterizes the index of the PO of the terminal.

[0027] Th Here, the first detection parameter can characterize a parameter determined based at least on the of the PO index i_s of the first terminal.

[0028] When actually adapting, there is a scenario where the transmission period of the first signal or one first channel is the same as the transmission period or time interval of PF. In this scenario, 1. When one first signal or one first channel corresponds to one or a plurality of POs, that is, one first signal or one first channel is to instruct the terminals of one PO or a plurality of POs whether they need to detect paging, the first detection parameter of the first terminal is characterized as the first index.

[0029] In this case, a correspondence relationship between \(i_s\) and a parameter for detecting a first signal or a first channel is defined in advance. When the first signal or the first channel is one 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. When 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. When the first signal or the first channel is a plurality of 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 the PDCCH or sequence detection position #0.

[0030] Combined with the specific example of FIG. 2, as shown in FIG. 2, the transmission period of PF is T1, and the transmission period of the first signal or the first channel, for example, PEI, is T2, and T1 = T2. One PF includes PO 1 and PO 2, and one first signal or first channel (PEI) corresponds to one PO. In this case, based on the first index of the first terminal, the detection parameter of the first signal or the first channel of the first terminal is determined, thereby determining the detection position of the first signal or the first channel.

[0031] When combined with the specific example of FIG. 3, as shown in FIG. 3, the transmission period of PF is T1, the transmission period of the first signal or the first channel, for example PEI, is T2, and T1 = T2. One PF includes PO 1 and PO 2, and one first signal or the first channel (PEI) corresponds to two POs. In this case, based on the first index of the first terminal, the detection parameters of the first signal or the first channel of the first terminal are determined, thereby detecting at least one of the detection parameters of the first signal or the first channel, such as the bit position, sequence cyclic shift, sequence index, and detection position.

[0032] 2. One first signal or one first channel corresponds to one or more terminal groups in one or more POs, that is, one first signal or one first channel is used to carry or indicate information on whether to detect paging of one or more terminal groups. The first detection parameter of the first terminal is determined based on the first index, the second index, and the first number.

[0033] Here, the second index th characterizes the index of the first terminal the terminal group to which it belongs The first number characterizes the number of terminal groups, and the first index characterizes the index of the PO of the terminal.

[0034] One first signal or one first channel (PEI), taking PEI as an example, is used to carry or indicate information on 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 characterizes the number of terminal groups within one PO, m characterizes the index of the first terminal in the corresponding terminal group, and i_s characterizes the index of the PO of the terminal. Specifically, a correspondence relationship between i_s*M+m and the parameter for detecting the first signal or the first channel is predefined. When the first signal or the first channel is one PDCCH and the index of the first terminal is i_s = 0, the first terminal detects the bit corresponding to or determined by 0*M+m in the PDCCH. When the first signal or the first channel is a sequence and the index of the first terminal is i_s = 0, the first terminal detects the cyclic shift or the sequence index of the sequence corresponding to or determined by 0*M+m. When the first signal or the first channel is a plurality of PDCCHs or sequences and the index of the first terminal is i_s = 0, the first terminal detects the PDCCH or the sequence at the PDCCH or sequence detection position corresponding to or determined by 0*M+m.

[0035] Combined with the specific example in FIG. 2, as shown in FIG. 2, the transmission period of PF is T1, the transmission period of the first signal or the first channel, for example PEI, is T2, and T1 = T2. One PF includes PO 1 and PO 2, and one first signal or one first channel (PEI) corresponds to one PO. In this case, based on i_s*M+m, the detection parameter of PEI by the first terminal is determined, thereby determining at least one of the detection parameters of the first signal or the first channel, such as the bit position, sequence cyclic shift, sequence index, and detection position.

[0036] In combination with the specific example of FIG. 3, as shown in FIG. 3, the transmission period of PF is T1, the transmission period of PEI is T2, and T1 = T2. One PF includes PO 1 and PO 2, and one PEI corresponds to two POs. In this case, based on i_s*M + m, the detection parameter of PEI by the first terminal is determined, whereby at least one of the detection parameters of the bit position, sequence cyclic shift, sequence index, and detection position of the first signal or the first channel is determined.

[0037] In actual adaptation, there is also a scenario where the transmission period of the first signal or the first channel is different from the transmission period of PF. In this scenario, 1. When one first signal or one first channel corresponds to one or more POs, that is, when one first signal or one first channel is used to indicate to the terminals of one or more POs whether it is necessary to detect paging, the first detection parameter of the first terminal is determined based on the first index and the first numerical value.

[0038] Here, the first numerical value is characterized as a numerical value determined by the system frame number of PF, the first time length, and the second time length. The first time length characterizes the time interval between adjacent first signals or adjacent first channels, and the second time length characterizes the time interval between adjacent PFs.

[0039] In one embodiment, the first numerical value is characterized as the first ratio divided by the second ratio. Here, the first ratio is characterized as the ratio of the system frame number of the PF to the second time length, and the second ratio is characterized as the ratio of the first time length to the second time length.

[0040] Taking PEI as an example, the first signal or the first channel and the PO have a one-to-one mapping relationship, and one first signal or one first channel corresponds to one PO. In this situation, illustratively, the first detection parameter can be determined based on (SFN / T1 mod K)*Ns + i_s, where SFN characterizes the system frame number of the PF. T1 characterizes the second time length, which is, that is, the time interval between two adjacent PFs and can be understood as the transmission period of the PF. K is characterized as the ratio of the first time length to the second time length, where the first time length characterizes the time interval between adjacent first signals or adjacent first channels and can be understood as the transmission period of the first signal or the first channel. Specifically, the correspondence between (SFN / T1 mod K)*Ns + 0 and the parameter for detecting the first signal or the first channel is defined in advance. When the first signal or the first channel is one PDCCH and the index of the first terminal is i_s = 0, the first terminal detects the bit corresponding to (SFN / T1 mod K)*Ns + 0 in the PDCCH. When the first signal or the first channel is a sequence and the index of the first terminal is i_s = 0, the first terminal detects the cyclic shift that is the sequence corresponding to (SFN / T1 mod K)*Ns + 0. When the first signal or the first channel is a plurality of PDCCHs or a plurality of sequences and the index of the first terminal is i_s = 0, the first terminal detects the corresponding PDCCH or sequence at the PDCCH or sequence detection position corresponding to (SFN / T1 mod K)*Ns + 0.

[0041] When combined with the specific example of FIG. 4, as shown in FIG. 4, the transmission period of PF is T1, the transmission period of the first signal or the first channel (PEI) is T2, and T2 = K * T1, where K characterizes an integer greater than 1. One PF includes PO 1 and PO 2, and one PEI corresponds to one PO. In this situation, based on (SFN / T1 mod K)*Ns + i_s, the detection parameter of the first signal or the first channel (PEI) by the first terminal is determined. Specifically, Ns = 2, T = 32 radio frames, that is, T = 320 ms, N = half T, that is, N = 16. Then, T1 = 2 radio frames, that is, T1 = 20 ms. If T2 = 40 ms, then K = 2, the SFN of PF1 is 0, and the SFN of PF2 is 2. Therefore, 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 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.

[0042] When combined with the specific example of FIG. 5, as shown in FIG. 5, the transmission period of PF is T1, the transmission period of the first signal or the first channel (PEI) is T2, and T2 = K * T1, where K is an integer greater than 1. One PF contains PO 1 and PO 2, and one PEI corresponds to a plurality of POs. In this situation, based on (SFN / T1 mod K) * Ns + i_s, the detection parameter of the first signal or the first channel (PEI) by the first terminal is determined. Specifically, Ns = 2, T = 32 radio frames, that is, T = 320 ms, N = half T, that is, N = 16. Then, T1 = 2 radio frames, that is, T1 = 20 ms. If T2 = 40 ms, 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 bit at 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 at 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 / T1 mod K) * Ns + i_s is 2, the terminal detects the bit at 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 at index 3 in the PDCCH or the sequence corresponding to the cyclic shift corresponding to index 3. 2. When one first signal or one first channel corresponds to one or a plurality of terminal groups in one or a plurality of POs, that is, when one first signal or one first channel is used to carry or indicate information on whether one or a plurality of terminal groups detect paging, the first detection parameter of the first terminal is determined based on the first index, the first numerical value, the second index, and the first number.

[0043] Here, the first numerical value is characterized as a numerical value determined by the system frame number of the paging frame PF, the first time length, and the second time length, and the second index is th characterizes the index of the first terminal the terminal group to which it belongs The first number characterizes the number of terminal groups, the first time length characterizes the transmission period of the signal or channel or the time interval between adjacent signals or channels, and the second time length characterizes the time interval between adjacent PFs.

[0044] In one embodiment, the first numerical value is characterized as the first ratio divided by the second ratio, where the first ratio is characterized as the ratio of the system frame number of the PF to the second time length, and the second ratio is characterized as the ratio of the first time length to the second time length.

[0045] In one embodiment, the method further includes the step of receiving a second ratio or a first time length set by the network side through a system message.

[0046] Taking PEI as an example, one first signal or one first channel (PEI) is used to carry or indicate information on whether one or more terminal groups detect paging. In this case, illustratively, the first detection parameter can be determined based on [(SFN / T1 mod K)*Ns + i_s]*M + m, where SFN characterizes the system frame number of PF, T1 characterizes the second time length, which is the time interval between two adjacent PFs, and can also be understood as the transmission period of PF, K characterizes the ratio of the first time length to the second time length, where the first time length characterizes the time interval between adjacent first signals or adjacent first channels, and this first time length can be understood as the transmission period of the first signal or the first channel, M characterizes the number of terminal groups in one PO, and m characterizes the index of the first terminal in the corresponding terminal group. Specifically, the correspondence between [(SFN / T1 mod K)*Ns + i_s]*M + m and the parameter for detecting the first signal or the first channel is defined in advance. When the first signal or the first channel is one PDCCH and the index of the first terminal is i_s = 0, the first terminal detects the PDCCH at the bit corresponding to [(SFN / T1 mod K)*Ns + 0]*M + m. When the first signal or the first channel is a sequence and the index of the first terminal is i_s = 0, the first terminal detects the sequence of the cyclic shift corresponding to [(SFN / T1 mod K)*Ns + 0]*M + m. When the first signal or the first channel is a plurality of PDCCHs or sequences, one PDCCH or sequence corresponds to one PO, and the index of the first terminal is i_s = 0, 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.

[0047] When combined with the specific example of FIG. 4, as shown in FIG. 4, the transmission period of PF is T1, the transmission period of PEI is T2, T2 = K * T1, where K is an integer greater than 1. One PF includes PO 1 and PO 2, 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.

[0048] When combined with the specific example of FIG. 5, as shown in FIG. 5, the transmission period of PF is T1, the transmission period of PEI is T2, T2 = K * T1, where K is an integer greater than 1. One PF includes PO 1 and PO 2, and one PEI corresponds to four POs in two PFs. In this situation, 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.

[0049] In the embodiments of the present application, based on the paging setting parameters of the first terminal, the first terminal determines the first detection parameter of the first signal or the first channel for instructing the terminal whether to detect paging. In the above solution, the terminal determines the first detection parameter of the first signal or the first channel based on its own paging setting parameters instead of the terminal-specific setting information sent by the network side. In this way, the setting of the first detection parameter of the first signal or the first channel does not require terminal-specific setting information any more, without causing additional signaling overhead, and the terminal can determine the first detection parameter of the first signal or the first channel even when it is in the idle state or the non-active state, achieving energy saving for the terminal.

[0050] To implement the method of the embodiments of the present application, the embodiments of the present application further provide a detection device for signals or channels provided in a first terminal.

[0053] In one embodiment, the first detection parameter of the first terminal is characterized as the first index, or the first detection parameter of the first terminal is determined based on the first index, a second index, and a first number, where the second index th characterizes an index of the first terminal the terminal group to which it belongs and the first number characterizes the number of terminal groups. In one embodiment, the determination of the first detection parameter of the first terminal based on the first index, the second index, and the first number includes that the first detection parameter is equal to the sum of the first product and the second index, and the first product is the product of the first index and the first number.

[0055] In one embodiment, the first numerical value is characterized as the first ratio divided by the second ratio, where the first ratio is characterized as the ratio of the system frame number of the PF to the second time duration, and the second ratio is characterized as the ratio of the first time duration to the second time duration.

[0056] In one embodiment, the apparatus includes a receiving unit configured to receive a second ratio or a first time duration set by the network side through a system message.

[0057] In actual adaptation, the determining unit 601 can be realized by a processor in a signal or channel detection device, and the receiving unit can be realized by a communication interface in the signal or channel detection device.

[0058] It should be noted that when the signal or channel detection device provided by the above embodiment performs signal or channel detection, only the division of the above program modules is taken as an example for explanation. In actual application, the above processing may be assigned to different program modules as needed to complete, that is, the internal structure of the device may be divided into different program modules to complete all or part of the above-described processing. Also, the signal or channel detection device provided by the above embodiment and the embodiment of the signal or channel detection method belong to the same concept.
