Description

Technical Field

[0002] In related technologies, the terminal can detect the demodulation reference signal (DMRS) sequence in the synchronization signal block (SSB).

[0003] In some scenarios, some terminals support detecting signals across the full bandwidth of an SSB, while others are limited in capability and can only detect signals across a portion of the SSB bandwidth. This leads to a performance loss in DMRS sequence detection. In other scenarios, multiple types of SSBs may exist; therefore, terminals need to perform DMRS sequence detection on different types of SSBs.

It is understood that the aforementioned functional modules can be network elements in hardware devices, software functional modules running on dedicated hardware, or virtualized functional modules instantiated on a platform (e.g., a cloud platform).

[0043] In related technologies, in order for a terminal to search for a suitable cell and synchronize with the selected cell, it is necessary to broadcast a synchronization signal and provide certain main information about the cell.

[0044] In an NR system, network-side devices can transmit Synchronization Signal Blocks (SSBs), which include the Primary Synchronization Signal (PSS), the Secondary Synchronization Signal (SSS), and the Physical Broadcast Channel (PBCH) (including PBCH-DMRS and PBCH payload). The PSS and SSS are used for signal synchronization, while the PBCH is used to transmit system messages. The PBCH carries the most important system information and is also known as the Master Information Block (MIB).

[0045] Figure 2This is a schematic diagram of the SSB structure in an NR system. In the frequency domain, the SSB consists of 240 consecutive subcarriers (i.e., 20 resource blocks (RBs)). In the time domain, it consists of four consecutive Orthogonal Frequency-Division Multiplexing (OFDM) symbols. The PSS is a sequence of length 127, mapped onto the first OFDM symbol, occupying the middle 127 subcarriers, with 56 and 57 subcarriers on either side not transmitting any signal. The SSS is a sequence of length 127, located on the third OFDM symbol of the SSB, occupying the middle 127 subcarriers, with 8 and 9 subcarriers on either side not transmitting any signal. The PBCH is located on the second to fourth OFDM symbols of the SSB. The second and fourth OFDM symbols each have 240 subcarriers, and the third OFDM symbol has 96 subcarriers. Therefore, the PBCH occupies a total of 576 resource elements (REs). DMRS occupies 1 / 4 of the RE resources, while the PBCH payload occupies the remaining 3 / 4 of the RE resources, which is 432 REs.

[0046] Channel bandwidth is the bandwidth of a single radio frequency (RF) carrier supported by an NR base station. NR base stations can support different channel bandwidths on the same carrier for sending or receiving signals to terminals connected to the base station. The carrier bandwidth available for data transmission within the channel bandwidth is called the transmission bandwidth. To avoid interference between adjacent channels, a certain guard band needs to be reserved at the edge of the channel bandwidth. The NR system defines the minimum guard band and maximum transmission bandwidth configuration corresponding to each channel bandwidth and subcarrier spacing.

[0047] To support narrowband terminals, the LTE system designed a completely new Narrow Band Internet of Things (NB-IoT) system and a new broadcast signal for it. The minimum channel bandwidth defined by the NR system is 5MHz. In order to enable NB-IoT terminals (such as 3MHz terminals) to access the NR system, the PBCH was pruned at the RB level. That is, the PBCH encoding is still based on 20 RB resources for encoding and resource mapping, the SSB structure remains unchanged, but the receiver only receives the PBCH and PSS / SSS within the middle 3MHz (12 RBs).

[0048] In related technologies, the DMRS sequence is a pseudo-random sequence whose initialization factors include the physical cell ID.

[0049] SSB index, half-frame number, etc. The terminal needs to use a certain number of DMRS sequences to perform blind detection on the received SSB to determine which DMRS sequence in the received SSB is which. After detecting the DMRS sequence, it can then infer part or all of the SSB's index information based on the determined DMRS sequence index.

[0050] In some scenarios, terminal capabilities are limited. For example, narrowband terminals have limited receiving bandwidth and can only receive a portion of the PBCH payload. Similarly, terminals can only receive a portion of the PBCH DMRS sequence. However, the number of DMRS sequences used by the terminal for blind detection is the same as that of the broadband terminal. This results in a loss in the DMRS sequence detection performance of the narrowband terminal compared to the broadband terminal. This is especially true when SSB coverage is poor. The correlation peaks of short sequences are too close, which may cause the terminal to misjudge the wrong DMRS sequence due to noise. This leads to the terminal interpreting the wrong SSB index, affecting subsequent demodulation performance.

[0051] In other scenarios, there may be multiple types of SSBs. Therefore, it is necessary to perform DMRS sequence detection on different types of SSBs. How to ensure the DMRS sequence detection performance of different types of SSBs is also an urgent problem to be solved.

[0052] The wireless communication method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0053] Figure 3 This is a schematic diagram of a wireless communication method provided in an embodiment of this application, such as... Figure 3 As shown, the method 200 may include at least some of the following:

[0054] S210, the first device receives the first signal;

[0055] Correspondingly, the second device sends the first signal;

[0056] S220, the first device determines at least one reference signal sequence in the first signal based on at least one sequence group, wherein each sequence group includes at least one candidate reference signal sequence, the at least one sequence group being related to the type of the first signal or at least a portion of the signals in the first signal.

[0057] In some embodiments, the first device may be a terminal or a component in the terminal, such as a chip, circuit, etc.

[0058] In some embodiments, the second device may be a first network-side device or a component of the first network-side device, such as a chip or circuit. The first network-side device may be the network-side device corresponding to the terminal, such as the network-side device of the cell where the terminal is located.

[0059] In some embodiments, the first signal may include an SSB, or may be replaced by a synchronization signal, a synchronization signal / physical broadcast channel block (SS / PBCH block), or any module that includes at least one of a synchronization signal, a broadcast signal, a broadcast channel (e.g., a physical broadcast channel (PBCH)), a wake-up signal (WUS), an activation signal, other system message downlink broadcast channels, or their control channels.

[0060] It should be understood that this application does not limit the terminal type of the first device. For example, the terminal type of the first device can be a first terminal type or a second terminal type, wherein the bandwidth supported by the first terminal type and the bandwidth supported by the second terminal type are different. For example, the bandwidth supported by the first terminal is less than the bandwidth supported by the second terminal type.

[0061] Optionally, the first terminal type can be a narrowband terminal, such as an NB-IoT terminal or a Low Power Wide Area (LPWA) terminal, and the second terminal type can be a broadband terminal, such as an Enhanced Mobile Broadband (eMBB) terminal.

[0062] It should be understood that this application does not limit the bandwidth size supported by the first terminal type, for example, it can be 1.4MHz, 3MHz, or other bandwidths.

[0063] It should be noted that, in the embodiments of this application, the reference signal sequence or candidate reference signal sequence can be a reference signal sequence used at least for channel demodulation or channel estimation, such as a demodulation reference signal (DMRS) sequence, or it can be other reference signal sequences, such as reference signal sequences used for time, frequency and phase estimation / tracking, such as tracking reference signals (TRS), phase tracking reference signals (PTRS), etc.; reference signal sequences used for channel measurement, such as channel state information reference signals (CSI-RS) sequences; and reference signal sequences used for positioning, such as positioning reference signals (PRS) sequences.

[0064] In the embodiments of this application, the sequence group is also called the reference signal sequence resource pool, such as the DMRS sequence resource pool or the DMRS sequence pool.

[0065] In some embodiments, the at least one sequence group may be predefined or configured by the second device. For example, the second device may configure the at least one sequence group to the first device through at least one of Media Access Control Control Element (MAC CE), Downlink Control Information (DCI), Radio Resource Control (RRC) signaling, and paging messages.

[0066] That is, in the embodiments of this application, sequence groups corresponding to different parts of the first signal can be configured or predefined, or sequence groups corresponding to different types of first signals can be configured or predefined. In this way, when the first device detects a reference signal sequence based on different parts of the first signal, it can perform detection based on the corresponding sequence groups, which is beneficial to improving the detection performance of the reference signal sequence. Alternatively, when the first device detects a reference signal sequence for different types of first signals, it can perform detection based on the corresponding sequence groups, which is beneficial to improving the detection performance of the reference signal sequence.

[0067] The following describes the design of a sequence group associated with at least a portion of the signals in the first signal, in conjunction with Example 1.

[0068] Example 1:

[0069] Optionally, in this embodiment 1, the second device may support at least one type of first signal. Different terminal types may use a unified first signal to perform reference signal sequence detection, and the target portion signal used to perform the reference signal sequence detection may be different. For example, the first terminal type may perform reference signal sequence detection based on a first portion of the first signal, the second terminal type may perform reference signal sequence detection based on a second portion of the first signal, or, based on both the first and second portions of the first signal, or based on all the signals in the first signal.

[0070] In some embodiments, the at least one sequence group being associated with at least a portion of the signals in the first signal can mean that the first device can selectively detect at least one reference signal sequence in the first signal by choosing at least one sequence group associated with at least a portion of the signals in the first signal. This at least one sequence group can be considered as the sequence group used by the first device to detect the at least one reference signal sequence in the first signal. The at least a portion of the signals can be a target portion of the first signal used to determine the at least one reference signal sequence.

[0071] That is, in the embodiments of this application, the first device can determine which sequence group to use to detect at least one reference signal sequence in the first signal based on the target part signal in the first signal. In other words, in the embodiments of this application, sequence groups corresponding to different parts of the first signal can be configured or predefined. In this way, the first device can perform reference signal sequence detection on different parts of the first signal based on the corresponding sequence group, which is beneficial to improving the detection performance of the reference signal sequence.

[0072] In some embodiments, the at least one sequence group includes a first sequence group that is associated with a first portion of the signal in the first signal, or, in other words, the first sequence group is associated with a signal on a first portion of the bandwidth of the first signal, or, the first sequence group is associated with a first terminal type.

[0073] It should be noted that, in the embodiments of this application, the first sequence group being related to the first part of the signal in the first signal may mean that the first sequence group is related to the reference signal sequence in the first part of the signal, that is, the first sequence group is used to detect the reference signal sequence in the first part of the signal.

[0074] In some embodiments, the method 200 further includes:

[0075] The first device can detect a first portion of the signal in the first signal based on a first sequence group to determine a first reference signal sequence in the first signal. In this case, the target portion of the signal can be considered to include the first portion of the signal in the first signal, and the at least one reference signal sequence includes the first reference signal sequence.

[0077] In other embodiments, the at least one sequence group includes a second sequence group that is associated with a second portion of the signal in the first signal, or that is associated with a signal on a second portion of the bandwidth of the first signal, or that is associated with a second terminal type.

[0078] It should be noted that, in the embodiments of this application, the second sequence group being related to the second part of the signal in the first signal may mean that the second sequence group is related to the reference signal sequence in the second part of the signal, that is, the second sequence group is used to detect the reference signal sequence in the second part of the signal.

[0079] In some embodiments, the method 200 further includes:

[0080] The first device can detect a second portion of the signal in the first signal based on a second sequence group to determine a second reference signal sequence in the first signal. In this case, the target portion of the signal can be considered to include the second portion of the signal in the first signal, and the at least one reference signal sequence includes the second reference signal sequence.

[0081] Optionally, when the type of the first device is the second terminal type, the second part of the signal in the first signal can be detected based on the second sequence group to determine the second reference signal sequence in the first signal.

[0082] In some other embodiments, the at least one sequence group includes a first sequence group and a second sequence group, wherein the first sequence group is associated with a first portion of the signal in the first signal (or, the signal on a first portion of the bandwidth of the first signal), and the second sequence group is associated with a second portion of the signal in the first signal (or, the signal on a second portion of the bandwidth of the first signal).

[0083] In some embodiments, the method 200 further includes:

[0084] The first device detects a first portion of the signal in the first signal based on a first sequence group to determine a first reference signal sequence in the first signal, and detects a second portion of the signal in the first signal based on a second sequence group to determine a second reference signal sequence in the first signal. In this case, the target portion of the signal can be considered to include both the first and second portions of the signal in the first signal, and the at least one reference signal sequence includes both the first and second reference signal sequences.

[0085] Optionally, when the type of the first device is the second terminal type, the first part of the signal in the first signal can be detected based on the first sequence group to determine the first reference signal sequence in the first signal, and the second part of the signal in the first signal can be detected based on the second sequence group to determine the second reference signal sequence in the first signal.

[0086] In some embodiments, the at least one sequence group includes a third sequence group that is associated with all signals in the first signal, or with signals across the entire bandwidth of the first signal, or with a second terminal type.

[0087] It should be noted that, in the embodiments of this application, the third sequence group being related to all signals in the first signal can mean that the third sequence group is related to all reference signal sequences in the first signal, that is, the third sequence group is used to detect the complete reference signal sequence in the first signal.

[0088] In some embodiments, the method 200 further includes:

[0089] The first device can detect all signals in the first signal based on the third sequence group to determine the third reference signal sequence in the first signal. In this case, the target portion of the signal can be considered to include signals across the entire bandwidth of the first signal, and the at least one reference signal sequence includes the third reference signal sequence.

[0090] Optionally, when the type of the first device is the second terminal type, all signals in the first signal can be detected based on the third sequence group to determine the third reference signal sequence in the first signal.

[0091] Optionally, the first portion of the bandwidth can be the receiving bandwidth supported by the first terminal type.

[0092] Optionally, the second portion of bandwidth can be the receiving bandwidth supported by the second terminal type, or it can be the bandwidth other than the first portion of bandwidth in the receiving bandwidth supported by the second terminal type.

[0093] Optionally, the second part of the bandwidth may be at least partially different from the first part of the bandwidth.

[0094] For example, the second portion of the bandwidth may include the bandwidth of the first signal received in addition to the first portion of the bandwidth.

[0095] As an example and not a limitation, the receiving bandwidth of the first signal is 5MHz, the first part of the bandwidth can be 3MHz, and the second part of the bandwidth can be 2MHz in addition to 3MHz.

[0096] Optionally, the first reference signal sequence and the second reference signal sequence can be the same, or they can be different.

[0097] Optionally, the first reference signal sequence and the second reference signal sequence can be generated in the same way or in different ways.

[0098] Optionally, the first device or the second device may determine the first reference signal sequence, the second reference signal sequence or the third reference signal sequence in the first signal according to a predefined formula or relevant parameters.

[0099] In some embodiments, at least one of the following is different in different sequence groups: the number of candidate reference signal sequences, the length of the candidate reference signal sequences, and the method of generating the candidate reference signal sequences.

[0100] For example, the first sequence group includes a first number (denoted as N1) of candidate reference signal sequences, the second sequence group includes a second number (denoted as N2) of candidate reference signal sequences, and the third sequence group includes a third number (denoted as N3) of candidate reference signal sequences.

[0101] Optionally, the first quantity and the second quantity are different, and / or, the first quantity and the third quantity are different, and / or, the second quantity and the third quantity are different.

[0102] Optionally, the third quantity may be the number of candidate reference signal sequences used to detect the complete reference signal sequence in the first signal. For example, the third quantity may be the same as the number of candidate DMRS sequences used to detect the complete DMRS sequence in the SSB in the NR system.

[0103] In some embodiments, the first quantity is related to a first portion of the signal in the first signal, and / or,

[0104] The second quantity is related to the second portion of the signal in the first signal; and / or,

[0105] The third quantity is related to all of the partial signals in the first signal.

[0106] Therefore, in this embodiment of the application, reference signal sequence detection based on different parts of the first signal can be configured or predefined to correspond to a corresponding number of candidate reference signal sequences. In this way, when the first device can perform reference signal sequence detection based on different parts of the first signal, it can be based on a corresponding number of candidate reference signal sequences, which is beneficial to meet the detection capabilities of reference signal sequences for different terminal types and improve the detection performance of reference signal sequences.

[0107] Optionally, the first quantity is less than the second quantity, and / or the first quantity is less than the third quantity.

[0108] When detecting a reference signal sequence based on the first portion of the first signal, the narrowband terminal has limited detection capabilities. Therefore, setting a small number of candidate reference signal sequences is sufficient to ensure the narrowband terminal's reference signal detection performance. When detecting a reference signal sequence based on all or the second portion of the first signal, the broadband terminal has stronger detection capabilities. Therefore, setting a larger number of candidate reference signal sequences is beneficial for ensuring the broadband terminal's reference signal detection performance.

[0109] Furthermore, by setting the number of candidate reference signal sequences for detecting the first part of the first signal in the first signal to be less than the number of candidate reference signal sequences for detecting the second part or all of the first signal in the second terminal type, this design is more compatible with the detection capabilities of the first and second terminal types, and can ensure that the system has better compatibility with different terminal types.

[0110] Optionally, the lengths of the candidate reference signal sequences included in the first sequence group and the lengths of the candidate reference signal sequences included in the second sequence group are different; and / or,

[0111] The lengths of the candidate reference signal sequences included in the first sequence group and the lengths of the candidate reference signal sequences included in the third sequence group are different; and / or,

[0112] The lengths of the candidate reference signal sequences included in the second sequence group are different from those included in the third sequence group.

[0113] Optionally, the length of the candidate reference signal sequence included in the first sequence group is less than the length of the candidate reference signal sequence included in the second sequence group; and / or

[0114] The length of the candidate reference signal sequence included in the first sequence group is less than the length of the candidate reference signal sequence included in the third sequence group.

[0115] When detecting a reference signal sequence based on the first portion of the first signal, since the narrowband terminal supports a narrow receiving bandwidth, setting the length of the corresponding candidate reference signal sequence to be short is beneficial to ensuring the reference signal detection performance of the narrowband terminal. When detecting a reference signal sequence based on all the signals in the first signal, since the broadband terminal supports a wide receiving bandwidth, setting the length of the corresponding candidate reference signal sequence to be long is beneficial to ensuring the reference signal detection performance of the broadband terminal.

[0116] Optionally, the candidate reference signal sequences included in the first sequence group may be generated in the same or different ways as the candidate reference signal sequences included in the second sequence group; and / or,

[0117] The candidate reference signal sequences included in the first sequence group are generated in the same or different ways as the candidate reference signal sequences included in the third sequence group; and / or,

[0118] The candidate reference signal sequences included in the second sequence group may be generated in the same or different ways as the candidate reference signal sequences included in the third sequence group.

[0119] The following describes the design of sequence groups related to the type of the first signal, in conjunction with Example 2.

[0120] Example 2:

[0121] Optionally, in this embodiment 2, the second device can support multiple types of first signals. For different types of first signals, the first device can use the corresponding sequence group to perform reference signal sequence detection, which is beneficial to improving the reference signal detection performance of different types of first signals.

[0122] Optionally, the multiple types of first signals can be multi-level SSBs, such as including a first-level SSB and a second-level SSB.

[0123] In some embodiments, the type of the first signal may be a first type, or a second type, or other types, which is not limited in this application.

[0124] Optionally, different types of first signals may correspond to different periods, and / or different bandwidths, or different triggering methods, etc., which are not limited in this application.

[0125] Optionally, the first signal of the first type can be a periodically transmitted signal, such as always on SSB, while the first signal of the second type is an on-demand (OD) triggered signal, such as OD-SSB.

[0126] Optionally, the first signal of the first type is a signal corresponding to the first terminal type, or in other words, a first signal used for receiving by the first terminal type; the first signal of the second type is a signal corresponding to the second terminal type, or in other words, a first signal used for receiving by the second terminal type.

[0127] In some embodiments, the at least one sequence group being associated with the type of the first signal can mean that the first device can select an associated sequence group to detect at least one reference signal sequence in the first signal based on the type of the first signal. For example, if the type of the first signal is a first type, the first device can select an associated sequence group of the first type to detect at least one reference signal sequence in the first signal. As another example, if the type of the first signal is a second type, the first device can select an associated sequence group of the second type to detect at least one reference signal sequence in the first signal.

[0128] That is, in the embodiments of this application, the first device can determine which sequence group to use to detect at least one reference signal sequence in the first signal based on the type of the first signal. In other words, in the embodiments of this application, sequence groups corresponding to different types of first signals can be configured or predefined. In this way, when the first device can select the corresponding sequence group based on the type of the first signal to perform reference signal sequence detection on the first signal, it is beneficial to improve the detection performance of the reference signal sequence.

[0129] In some embodiments, the first signal is of a first type, and the at least one sequence group includes a fourth sequence group, the fourth sequence group being associated with the first signal of the first type; or

[0130] The first signal is of type two, and the at least one sequence group includes a fifth sequence group, which is associated with the first signal of type two.

[0131] In some embodiments, the method 200 further includes:

[0132] The first device can detect a first signal of a first type based on a fourth sequence group to determine a fourth reference signal sequence in the first signal. In this case, it can be assumed that the at least one reference signal sequence includes the fourth reference signal sequence.

[0133] In some embodiments, the method 200 further includes:

[0134] The first device can detect the first signal of the second type based on the fifth sequence group to determine the fifth reference signal sequence in the first signal. In this case, it can be assumed that the at least one reference signal sequence includes the fifth reference signal sequence.

[0135] Optionally, in this embodiment 2, at least one of the following is different: the number of candidate reference signal sequences, the length of the candidate reference signal sequences, and the generation method of the candidate reference signal sequences included in different sequence groups.

[0136] For example, the fourth sequence group includes a fourth number of candidate reference signal sequences, and the fifth sequence group includes a fifth number of candidate reference signal sequences.

[0137] Optional, the fourth and fifth quantities are different.

[0138] In some embodiments, the fourth quantity is related to the first signal of the first type, and / or,

[0139] The fifth quantity is related to the first signal of the second type.

[0140] Therefore, in this embodiment of the application, the reference signal sequence detection of different types of first signals can be configured or predefined to correspond to a corresponding number of candidate reference signal sequences. In this way, when the first device can perform reference signal sequence detection on different types of first signals, it can improve the reference signal sequence detection performance of different types of first signals based on the corresponding number of candidate reference signal sequences.

[0141] Optional, the fourth quantity is less than the fifth quantity.

[0142] For example, when the first signal of the first type is the signal corresponding to the first terminal type, and the first signal of the second type is the signal corresponding to the second terminal type, the fourth quantity is less than the fifth quantity.

[0143] Because narrowband terminals have limited detection capabilities, such as narrow bandwidth and short supported sequence lengths, while broadband terminals have stronger detection capabilities, such as wide bandwidth and longer supported sequence lengths, fewer candidate reference signal sequences can be configured or predefined for reference signal sequence detection of narrowband terminals, while more candidate reference signal sequences can be configured or predefined for reference signal sequence detection of broadband terminals. This is beneficial for ensuring the reference signal detection performance of different terminal types.

[0144] Furthermore, by setting the number of candidate reference signal sequences for detecting the first signal of the first type by the first terminal type to be less than the number of candidate reference signal sequences for detecting the first signal of the second type by the second terminal type, this design is more compatible with the detection capabilities of the first and second terminal types, and can ensure that the system has better compatibility with different terminal types.

[0145] For example, when the first signal of the first type is always on SSB and the first signal of the second type is OD-SSB, the fourth quantity is less than the fifth quantity.

[0146] Since OD-SSB has a narrower beam than always on SSB, it has better coverage and can perform beam training in advance. It requires more reference signal sequences to indicate the SSB index. Therefore, for reference signal sequence detection of OD-SSB, a larger number of candidate reference signal sequences can be configured, while for reference signal sequence detection of always on SSB, a smaller number of candidate reference signal sequences can be configured. This is beneficial to ensure the reference signal detection performance of different types of first signals.

[0147] Optionally, the lengths of the candidate reference signal sequences included in the fourth sequence group and the fifth sequence group may differ.

[0148] For example, when the first signal of the first type is the signal corresponding to the first terminal type, and the first signal of the second type is the signal corresponding to the second terminal type, the length of the candidate reference signal sequence included in the fourth sequence group is less than the length of the candidate reference signal sequence included in the fifth sequence group.

[0149] Because narrowband terminals support shorter sequence lengths, setting the corresponding candidate reference signal sequence to be shorter helps ensure the reference signal detection performance of narrowband terminals. Conversely, because broadband terminals support longer sequence lengths, setting the corresponding candidate reference signal sequence to be longer helps ensure the reference signal detection performance of broadband terminals.

[0150] Optionally, the generation method of the candidate reference signal sequence included in the fourth sequence group may be the same as or different from the generation method of the candidate reference signal sequence included in the fifth sequence group, and this application does not limit this.

[0151] In some embodiments, the candidate reference signal sequences included in the fourth sequence group and the fifth sequence group may be partially the same or completely different, and the number of candidate reference signal sequences included in the fourth sequence group and the fifth signaling group may be different. For example, the fourth sequence group may include the sequence {s1,s2,…,s4}, and the fifth sequence group may include the sequence {s1,s2,…,s4,s5,…,s8}. In this case, the candidate reference signal sequences included in the fourth sequence group and the fifth sequence group are partially the same. As another example, the fourth sequence group may include the sequence {s1,s2,…,s4}, and the fifth sequence group may include the sequence {w1,w2,…,w4,w5,…,w8}. In this case, the candidate reference signal sequences included in the fourth sequence group and the fifth sequence group are completely different.

[0152] In some embodiments, the fifth quantity is indicated by a first signal of a first type, such as by a PBCH of a first signal of a first type.

[0153] For example, the first device may receive a first signal of a first type, detect at least one reference signal sequence in the first signal of the first type based on a fourth sequence group, further demodulate the PBCH carried in the first signal based on the at least one reference signal sequence, and obtain the number of candidate reference signal sequences for detecting the first signal of a second type from the PBCH.

[0154] In some embodiments, the method 200 further includes:

[0155] In the event that the reference signal sequence detection in the first signal of the first type fails, the first device sends a trigger signal or feedback information of the first signal of the first type to the second device. The trigger signal is used to trigger the second device to send the first signal of the second type, and the feedback information is used to indicate that the reference signal sequence detection in the first signal of the first type has failed.

[0156] In some embodiments, the first device may determine whether a reference signal sequence in the first signal of a first type has failed to be detected based on a detection threshold, which may be predefined or configured by the second device.

[0157] For example, the terminal can detect the first signal of the first type based on the fourth sequence group. If the number of candidate reference signal sequences whose detected correlation peak is greater than the detection threshold is greater than 1, the first device can determine that the detection performance is poor and send a trigger signal on the agreed uplink resources. Alternatively, the feedback information can be used to trigger the second device to send the first signal of the second type.

[0158] Correspondingly, the second device can agree on an uplink resource receiving trigger signal or feedback information. Upon receiving such a trigger signal or feedback information, the second device can send a first signal of the second type.

[0159] Optionally, the trigger signal can be WUS, or other uplink signals, which are not limited in this application.

[0160] In some embodiments, the method 200 further includes:

[0161] The first device determines the type of the first signal based on at least one of the following:

[0162] The synchronization sequence in the first signal, such as PSS and / or SSS;

[0163] The resource location of the first signal;

[0164] Trigger signals, such as WUS.

[0165] Optionally, the first signal can be distinguished as either type one or type two by different synchronization sequences (e.g., PSS or SSS) in the first signal.

[0166] Optionally, the resource location of the first signal may include, but is not limited to, at least one of the following:

[0167] The resource location of the reference signal sequence in the first signal, for example, the resource location of the reference signal sequence is different in different types of first signals;

[0168] The search period for the first signal, for example, the search period for different types of first signals is different;

[0169] The frequency domain location of the first signal, for example, the frequency domain location is different for different types of first signals;

[0170] The time domain location of the first signal, for example, the time domain location of the first signal is different for different types of signals.

[0171] Optionally, the WUS may include indication information for indicating which type of first signal is triggered, so that the first device can determine the type of the subsequently received first signal based on the indication information in the WUS.

[0172] Specifically, after determining the type of the first signal based on the above information, the first device can further detect the reference signal sequence in the first signal based on the corresponding sequence group. This is beneficial for the first device to detect the reference signal sequence of the first signal based on a suitable sequence group, thereby improving the detection performance of the reference signal sequence.

[0173] In the embodiments of this application, the number of candidate reference signal sequences included in each sequence group may be predefined, or configured by the second device (e.g., configured by the synchronization sequence in the first signal, configured by WUS or broadcast messages or paging messages, etc.), or determined based on the relevant configuration of the first signal (e.g., period, time domain resources, frequency domain resources, type, etc.), or determined according to the capabilities of the first device, or may be indicated by other network-side devices other than the second device.

[0174] In some embodiments, the number of the at least one candidate reference signal sequence included in each sequence group (e.g., the aforementioned first sequence group, second sequence group, third sequence group, fourth sequence group, or fifth sequence group) is determined based on first information, the first information including at least one of the following:

[0175] Predefined information;

[0176] The synchronization sequence in the first signal, such as PSS and / or SSS;

[0177] Signaling from network-side devices other than the second device, where the second device is the network-side device corresponding to the first device;

[0178] The position of the sync raster of the first signal;

[0179] The type of the first signal;

[0180] The transmission period of the first signal;

[0181] The timing of the transmission of the first signal;

[0182] The bandwidth type of the first signal, such as TN broadband or NTN broadband;

[0183] The frequency range of the first signal;

[0184] WUS;

[0185] Downlink reference signals, such as CSI-RS or SRS reference signals;

[0186] Broadcast messages, such as SIB1;

[0187] Paging messages;

[0188] The capabilities of the first device.

[0189] Optionally, signaling from other network-side devices may include, but is not limited to, signaling from network-side devices associated with other cells, TRPs, carriers, bandwidths, or subbands, such as RRC signaling, MAC signaling, or physical layer signaling from other cells. Here, "other cells, TRPs, carriers, bands, or subbands" refers to cells, TRPs, carriers, bandwidths, or subbands relative to the cell, TRP, carrier, bandwidth, or subband where the first device is located.

[0190] In some embodiments, the capabilities of the first device may include, but are not limited to, the ability of the first device to detect the first signal.

[0191] In some embodiments, the detection capability includes, but is not limited to, at least one of the following:

[0192] The detection time of the synchronization sequence in the first signal;

[0193] The detection time of the first index (e.g., SSB index) corresponding to the first signal;

[0194] The first device supports the detection of the maximum number of candidate reference signal sequences on which the reference signal sequence in the first signal is based;

[0195] The receiving bandwidth of the first signal supported by the first device;

[0196] The bandwidth type of the first signal supported by the first device;

[0197] The frequency range of the first signal supported by the first device.

[0198] Therefore, in this embodiment of the application, the number of candidate reference signal sequences included in each sequence group can be determined based on the first information mentioned above. This is beneficial for setting an appropriate number of candidate reference signal sequences for first signals with different configurations or first devices with different capabilities, thereby improving the detection performance of the reference signal sequences.

[0199] For example, if the receiving bandwidth of the first signal supported by the first device is the aforementioned first portion bandwidth, the second device can configure a first sequence group for the first device, including a first number of candidate reference signal sequences.

[0200] For example, if the detection time of the first index corresponding to the first device is long, it can be determined that the number of candidate reference signal sequences included in the sequence group configured for the first device is small.

[0201] For example, it can be determined that the number of candidate reference signal sequences included in the sequence group configured for the first device does not exceed the maximum number of candidate reference signal sequences that the first device supports detecting.

[0202] The following, in conjunction with Embodiment 3, describes the method for determining the first index and / or time-related information corresponding to the first signal provided in the embodiments of this application.

[0203] Example 3:

[0204] In some embodiments, the first signal is an SSB, the first index corresponding to the first signal can be an SSB index, and time-related information can include a half-frame index.

[0205] In some embodiments, the at least one reference signal sequence in the first signal may be associated with a first index corresponding to the first signal, or may not be associated with it. For example, the first device may determine the first index based on the at least one reference signal sequence, or determine a portion of the first index, or determine the first index based on other information.

[0206] In some embodiments, the at least one reference signal sequence in the first signal may be related to the time-related information corresponding to the first signal, or it may not be related. For example, the first device may determine the time-related information based on the at least one reference signal sequence, or determine a portion of the time-related information, or determine the time-related information based on other information.

[0207] In some embodiments of this application, the method 200 further includes:

[0208] The second device indicates the first index corresponding to the first signal and / or the time-related information corresponding to the first signal through the at least one reference signal sequence and / or the second information.

[0209] Correspondingly, the first device determines the first index corresponding to the first signal and / or the time-related information corresponding to the first signal based on the at least one reference signal sequence and / or the second information.

[0210] For example, the first device can determine the complete first index based on the at least one reference signal sequence, or determine a partial index in the first index based on the at least one reference signal sequence and further combine it with the second information to determine the complete first index, or it can determine the complete first index based on the second information.

[0211] In some embodiments, the second information includes at least one of the following:

[0212] Resource information of the first signal;

[0213] The load of PBCH in the first signal;

[0214] WUS;

[0215] The synchronization sequence in the first signal;

[0216] Signaling from network-side devices other than the second device, where the second device is the network-side device corresponding to the first device;

[0217] The position of the synchronization grid of the first signal;

[0218] The type of the first signal;

[0219] The transmission period of the first signal;

[0220] The timing of the transmission of the first signal;

[0221] The bandwidth type of the first signal, such as TN broadband or NTN broadband, etc.;

[0222] The frequency range of the first signal;

[0223] Downlink reference signals, such as CSI-RS or SRS;

[0224] Broadcast message;

[0225] Paging messages;

[0226] The capabilities of the first device, such as its ability to detect a reference signal sequence.

[0227] Optionally, the resource information of the first signal may include, but is not limited to, time-domain resources and / or frequency-domain resources.

[0228] Optionally, different resource information of the first signal may correspond to different index values ​​of the first index, or different values ​​of a portion of the first index. The first device can then determine the specific index value of the first index, or the value of a portion of the first index, based on the resource location of the first signal. Optionally, the complete value of the first index can be determined by further combining the values ​​of a portion of the first index determined based on at least one reference signal sequence.

[0229] Optionally, the load of the PBCH in the first signal can indicate different index values ​​of the first index, or different values ​​of a portion of the first index. The first device can then determine the specific index value of the first index, or the value of a portion of the first index, based on the load of the PBCH in the first signal. Optionally, the complete value of the first index can be determined further by combining the values ​​of a portion of the first index determined based on at least one reference signal sequence.

[0230] For example, the lower 3 bits of the first index are determined based on the at least one reference signal sequence, the higher 3 bits of the first index are determined based on the load of PBCH in the first signal, and the 6 bits are further combined to obtain the complete first index.

[0231] Optionally, different index values ​​of the first index, or different values ​​of a portion of the first index, can be indicated by WUS, downlink reference signals, broadcast messages, or paging messages. Then, the first device can determine the specific index value of the first index, or the value of a portion of the first index, based on WUS, downlink reference signals, broadcast messages, or paging messages. Optionally, the complete value of the first index can be determined by combining the values ​​of a portion of the first index determined based on at least one reference signal sequence.

[0232] Optionally, different index values ​​of the first index can be indicated by a synchronization sequence (e.g., PSS or SSS) in the first signal, or different values ​​of a portion of the first index. The first device can then determine the specific index value of the first index, or the value of a portion of the first index, based on the synchronization sequence in the first signal. Optionally, the complete value of the first index can be determined further by combining the values ​​of a portion of the first index determined based on at least one reference signal sequence.

[0233] Optionally, signaling from other network-side devices can indicate different index values ​​of the first index, or different values ​​of a portion of the first index. The first device can then determine the specific index value of the first index, or the value of a portion of the first index, based on the signaling from other network-side devices. Optionally, the complete value of the first index can be determined further by combining the values ​​of a portion of the first index determined based on at least one reference signal sequence.

[0234] Optionally, different synchronization grid positions of the first signal may correspond to different index values ​​of the first index, or different values ​​of a portion of the first index. The first device can then determine the specific index value of the first index, or the value of a portion of the first index, based on the synchronization grid position of the first signal. Optionally, the complete value of the first index can be determined by further combining the values ​​of a portion of the first index determined based on at least one reference signal sequence.

[0235] Optionally, different transmission periods of the first signal may correspond to different index values ​​of the first index, or different values ​​of a portion of the first index. The first device can then determine the specific index value of the first index, or the value of a portion of the first index, based on the transmission period of the first signal. Optionally, the complete value of the first index can be determined by further combining the values ​​of a portion of the first index determined based on at least one reference signal sequence.

[0236] Optionally, different transmission times of the first signal may correspond to different index values ​​of the first index, or different values ​​of a portion of the first index. The first device can then determine the specific index value of the first index, or the value of a portion of the first index, based on the transmission time of the first signal. Optionally, the complete value of the first index can be determined by further combining the values ​​of a portion of the first index determined based on at least one reference signal sequence.

[0237] Optionally, different bandwidth types of the first signal may correspond to different index values ​​of the first index, or different values ​​of a portion of the first index. The first device can then determine the specific index value of the first index, or the value of a portion of the first index, based on the bandwidth type of the first signal. Optionally, the complete value of the first index can be determined by further combining the values ​​of a portion of the first index determined based on at least one reference signal sequence.

[0238] Optionally, different frequency band ranges of the first signal may correspond to different index values ​​of the first index, or different values ​​of a portion of the first index. The first device can then determine the specific index value of the first index, or the value of a portion of the first index, based on the frequency band range of the first signal. Optionally, the complete value of the first index can be determined by further combining the values ​​of a portion of the first index determined based on at least one reference signal sequence.

[0239] In some embodiments, the first device determines a first index of the first signal based on the at least one reference signal sequence and / or second information, including:

[0240] The first device determines the lower X bits of the first index based on the second information, where X is a positive integer.

[0241] In some embodiments, the first device determines a first index of the first signal based on the at least one reference signal sequence and / or second information, including:

[0242] Under specific conditions, the first device determines the lower X bits of the first index based on the second information, where X is a positive integer.

[0243] Optionally, the specific condition may include at least one of the following:

[0244] The frequency band of the first signal is the first frequency band;

[0245] The frequency band of the first signal is within the first frequency range;

[0246] The first signal is the first-level signal, such as the first-level SSB;

[0247] The second device supports sending a single-level signal, meaning there are no multi-level signals, such as multiple-level SSBs, or multiple types of first signals.

[0248] The period of the first signal is within a specific period range.

[0249] Because different types of terminals have different capabilities, the detection performance of the reference signal sequence for the first signal also varies. Determining the first index relies on the detection of the reference signal sequence, which requires the detection performance of the reference signal sequence to meet certain requirements. If the first device detects an incorrect reference signal sequence, it will cause the first device to interpret an incorrect first index, affecting the subsequent data demodulation performance. In this embodiment, the first index can be determined based on information other than the at least one reference signal sequence, which helps ensure that the first device interprets the correct first index.

[0250] Optionally, the lower X bits can be the lower 3 bits, or other numbers of bits, which are not limited in this application.

[0251] As an example, the lower X bits are indicated by the payload of the PBCH. If the total number of first indices is less than 5, the first index can be indicated by 2 bits in the payload of the PBCH, and the other bit can be used for other purposes or reserved.

[0252] Optionally, for the transmission of a first signal in a first frequency band or within a first frequency range, the lower X bits of the first index can be indicated by second information. Optionally, for the transmission of a first signal in a second frequency band or within a second frequency band, the lower X bits can be indicated by a reference signal sequence, in which case the lower X bits of the first index can be known before PBCH decoding.

[0253] Optionally, the first frequency band range can be a frequency band range with frequencies lower than a first frequency threshold. The second frequency band range can be a frequency band range with frequencies higher than the first frequency threshold. Since the number of first signals in the low frequency band or frequency range is small (i.e., the number of first indices is small), it is sufficient to indicate the low X bits using only the second information. Therefore, in this case, the first index can be determined without relying on the reference signal sequence.

[0254] In some embodiments, the type of the first device is a first terminal type, and the at least one reference signal sequence and the first index and / or the time-related information determined by the first device are unrelated.

[0255] That is, for the first terminal type, the first index and / or the time-related information are not determined by the reference signal sequence. In this case, they can be determined based on the second information.

[0256] In some embodiments, the first device is of a second terminal type, and the at least one reference signal sequence determined by the first device is related to the first index and / or the time-related information.

[0257] That is, for the second terminal type, the first index and / or the time-related information are determined by a reference signal sequence.

[0258] Optionally, regardless of whether the first device is a first terminal type or a second terminal type, the at least one reference signal sequence and the first index and / or the time-related information determined by the first device are either unrelated or all related.

[0259] That is, for both the first and second terminal types, the first index and / or the time-related information are determined in the same way.

[0260] In some embodiments, the second device indicates a first index corresponding to the first signal and / or time-related information corresponding to the first signal through the at least one reference signal sequence and / or second information, including at least one of the following:

[0261] The first reference signal sequence indicates the first index and / or the time-related information;

[0262] The first index and / or the time-related information are indicated by a second reference signal sequence;

[0263] The first index and / or the time-related information are indicated by the first reference signal sequence and the second reference signal sequence;

[0264] The first index and / or the time-related information are indicated by a third reference signal sequence.

[0265] Correspondingly, the first device determines a first index corresponding to the first signal and / or time-related information corresponding to the first signal based on the at least one reference signal sequence and / or the second information, including at least one of the following:

[0266] The first device determines the first index and / or the time-related information based on the first reference signal sequence;

[0267] The first device determines the first index and / or the time-related information based on the second reference signal sequence;

[0268] The first device determines the first index and / or the time-related information based on the first sub-index and the second sub-index, wherein the first sub-index is determined based on the first reference signal sequence, and the second sub-index is determined based on the second reference signal sequence;

[0269] The first device determines the first index and / or the time-related information based on the third reference signal sequence.

[0270] It should be understood that the way the second device indicates the first index corresponding to the first signal and / or the time-related information corresponding to the first signal to the first device corresponds to the way the first device determines the first index corresponding to the first signal and / or the time-related information corresponding to the first signal.

[0272] Optionally, when the first device is of the second terminal type, the first device can determine the first index and / or the time-related information based on the second reference signal sequence. Alternatively, the first index and / or the time-related information can be determined based on the first reference signal sequence and the second reference signal sequence, for example, by determining the first index and / or the time-related information based on the first sub-index and the second sub-index. Alternatively, the first index and / or the time-related information can be determined based on the third reference signal sequence.

[0273] In some embodiments, the first device determines the first index and / or the time-related information based on a first reference signal sequence, including:

[0278] Optionally, the first reference signal sequence index can be used as the first index, or the first reference signal sequence index can be used as a partial index of the first index, such as the lower 3 bits or the higher 3 bits.

[0279] In some embodiments, the first device determines the first index and / or the time-related information based on a second reference signal sequence, including:

[0280] The first device can detect and determine the second reference signal sequence based on a second number (i.e., N2) of candidate reference signal sequences in the second sequence group;

[0288] The first device can detect and determine the second reference signal sequence based on a second number (i.e., N2) of candidate reference signal sequences in the second sequence group;

[0289] A first sub-index is determined based on the first reference signal sequence, such as a first reference signal sequence index, and a second sub-index is determined based on the second reference signal sequence, such as a second reference signal sequence index, wherein the first reference signal sequence index is used to indicate the first reference signal sequence, and the second reference signal sequence index is used to indicate the second reference signal sequence.

[0290] The first index and / or the time-related information are determined based on the first sub-index and the second sub-index. For example, a target reference signal sequence index is determined based on the first reference signal sequence index and the second reference signal sequence index, and the first index and / or the time-related information are determined based on the target reference signal sequence index. The combination of the target reference signal sequence index can be N1*N2.

[0291] Optionally, the first reference signal sequence index can be a first DMRS sequence index, and the second reference signal sequence index can be a second DMRS sequence index.

[0292] Optionally, the maximum value of the first sub-index or the first reference signal sequence index is a first quantity, and the maximum value of the second sub-index or the second reference signal sequence index is a second quantity.

[0293] Optionally, the first sequence group used by the second terminal type to determine the first reference signal sequence index is the same as the first sequence group used by the first terminal type to determine the first reference signal sequence index. The second sequence group used by the second terminal type to determine the second reference signal sequence index and the first sequence group used to determine the first reference signal sequence index can be the same or different. Optionally, the first device can use the first reference signal sequence index as the high Y bits or low Z bits of the target reference signal sequence index, and use the second reference signal sequence index as the low Z bits or high Y bits of the target reference signal sequence index. The target reference signal index can be a combination of the Y+Z bits. Further, the target reference signal sequence index can be determined as the first index, or a partial index of the first index can be determined based on the target reference signal sequence index, such as the high Y bits or low Z bits, where Y and Z are positive integers.

[0294] Optionally, taking Y and Z as three examples, the first device can use the first reference signal sequence index as the high 3 bits or low 3 bits of the target reference signal sequence index, and use the second reference signal sequence index as the low 3 bits or high 3 bits of the target reference signal sequence index. That is, the target reference signal index can be the combined 6 bits. Further, the target reference signal sequence index can be determined as the first index, or a partial index of the first index can be determined based on the target reference signal sequence index, such as the low 3 bits or the high 3 bits, etc.

[0295] In some other embodiments, the first device determines the first index and / or the time-related information based on a first reference signal sequence and a second reference signal sequence, including:

[0296] The first device can detect and determine the first reference signal sequence based on a first number (i.e., N1) candidate reference signal sequences in the first sequence group;

[0297] The first device can detect and determine the second reference signal sequence based on a second number (i.e., N2) of candidate reference signal sequences in the second sequence group;

[0298] The complete reference signal sequence, i.e. the target reference signal sequence, is determined based on the first reference signal sequence and the second reference signal sequence.

[0299] Determine the target reference signal sequence index (e.g., the target DMRS sequence index);

[0300] The first index and / or the time-related information are determined based on the target reference signal sequence index.

[0301] Optionally, the maximum value of the target reference signal sequence index is the third number.

[0302] In other embodiments, the first device determines the first index and / or the time-related information based on a third reference signal sequence, including:

[0303] The first device can detect and determine the third reference signal sequence based on the third number (i.e., N3) candidate reference signal sequences in the third sequence group;

[0304] Determine the third reference signal sequence index (e.g., the third DMRS sequence index);

[0305] The first index and / or the time-related information are determined based on the third reference signal sequence index.

[0306] Optionally, the maximum value of the third reference signal sequence index is the third quantity.

[0307] Optionally, the third sequence group used by the second terminal type to determine the third reference signal sequence index can be the same as, or different from, the first sequence group used to determine the first reference signal sequence index and the second sequence group used to determine the second reference signal sequence index. For example, the third sequence group may include candidate reference signal sequences from the first and second sequence groups.

[0308] In some embodiments, the first reference signal sequence is identical to a portion of the third reference signal sequence.

[0309] For example, the length of the third reference signal sequence is X, and the first reference signal sequence is a sequence of length X1 in the third reference signal sequence, where X1 is less than X. Optionally, the second reference signal sequence can be a sequence of length X2 in the third reference sequence, where the first and second reference signal sequences can form the third reference signal sequence, where X1 + X2 = X. Optionally, the third reference signal sequence can be considered as a complete reference signal sequence in the first signal.

[0310] Optionally, the first reference signal sequence index can be a portion of the third reference sequence index, such as the lower 3 bits or the higher 3 bits. Optionally, the second reference signal sequence index can be a portion of the third reference sequence index, such as the higher 3 bits or the 3 bits.

[0311] In some embodiments, the narrowband terminal supports receiving 8 SSBs per cycle, so the maximum value of the SSB index is 8, which requires 3 bits to indicate. The first sequence group may include 8 candidate reference signal sequences. The narrowband terminal can detect the first part of the signal in the first signal based on the 8 candidate reference signal sequences to determine the 3-bit reference signal sequence index (i.e., the first reference signal sequence index). Furthermore, the 3-bit reference signal sequence index can be used as the first index of the first signal.

[0312] For a broadband terminal, each SSB cycle supports receiving 64 SSBs, so the maximum value of the SSB index is 64, which requires 6 bits for indication. The first sequence group can include 8 candidate reference signal sequences, and the second sequence group can also include 8 reference signal sequences. The broadband terminal can use the first sequence group to detect the first part of the signal in the first signal to determine a 3-bit (e.g., low 3 bits or high 3 bits) reference signal sequence index (i.e., the first reference signal sequence index), and use the second sequence group to detect the second part of the signal in the first signal to determine a 3-bit (e.g., high 3 bits or low 3 bits) reference signal sequence index (i.e., the second reference signal sequence index). The 6 bits are then combined as the first index corresponding to the first signal.

[0313] The following describes, with reference to Embodiment 4, a joint detection method for signals on different frequency domain resources provided in this application. It should be understood that Embodiment 4 can be implemented alone, or it can be implemented in combination with at least one of the aforementioned Embodiments 1, 2 or 3, and this application does not limit it in this regard.

[0314] In some embodiments, the first signal on some frequency domain resources may be active or turned on, while the first signal on some frequency domain resources may be deactivated or turned off. In the embodiments of this application, the association relationship of the first signals on different frequency domain resources can be introduced to facilitate the network-side device in determining which frequency domain resources support the access of the first device. Therefore, the attribute relationship between the first signals on different frequency domain resources, such as the quasi-co-located (QCL) relationship, can be considered to design the reference signal sequence corresponding to the first signal with the association relationship.

[0315] In some embodiments of this application, the method 200 further includes:

[0316] The first device receives first configuration information from the second device. The first configuration information is used to configure the first signal on the first frequency domain resource to be associated with the second signal on the second frequency domain resource, or the first signal on the first frequency domain resource to be associated with the second frequency domain resource.

[0317] Optionally, the first frequency domain resources may include, but are not limited to, at least one of the following:

[0318] First cell, first TRP, first carrier, first bandwidth, first subband, first BWP.

[0319] Optionally, the second frequency domain resources may include, but are not limited to, at least one of the following:

[0320] Second cell, second TRP, second carrier, second bandwidth, second subband, second BWP.

[0321] Optionally, in this embodiment 4, the first signal can be a periodically transmitted signal, such as always onSSB, and the second signal can be a non-periodic transmitted signal or a signal transmitted on demand, such as OD-SSB.

[0322] Optionally, the reference signal sequence configuration of the first signal and the reference signal sequence configuration of the second signal can be the same or different.

[0323] In some embodiments, the first signal includes a reference signal sequence, while the second signal does not. That is, the first device can perform reference signal sequence detection and channel estimation on the first signal, without needing to perform reference signal sequence detection and channel estimation on the second signal. In this case, the PBCH in the second signal can be demodulated using the channel estimated from the reference signal sequence in the first signal, saving resources occupied by the reference signal sequence and improving resource utilization. For example, the first signal is a first SSB, and the second signal is a second SSB. The first SSB may include a DMRS sequence, while the second SSB may not. Optionally, the PBCH of the second SSB can be demodulated using the DMRS sequence in the first SSB.

[0324] In some embodiments, the number of candidate reference signal sequences used to detect the second signal is less than the number of candidate reference signal sequences used to detect the first signal.

[0325] For example, the first signal is always on SSB, and the second signal is OD-SSB. The number of candidate reference signal sequences used to detect OD-SSB is less than the number used to detect always on SSB. Since OD-SSB is based on trigger signal transmission, in practical applications, it may only be necessary to trigger a portion of the coverage area corresponding to the SSB index. Therefore, it is not necessary to support too many SSB indices, which can reduce the number of reference signal sequences in the SSB, allowing the terminal to detect fewer sequences and improving detection performance.

[0326] In some embodiments, when the first signal on a first frequency domain resource is associated with a second signal on a second frequency domain resource, or when the first signal on the first frequency domain resource is associated with the second frequency domain resource, the first device may perform a first operation based on the measured value of the first signal.

[0327] The first operation includes at least one of the following:

[0328] Activate the second frequency domain resource associated with the first signal;

[0329] Activate the second reference signal on the second frequency domain resource associated with the first signal;

[0330] Determine the transmission parameters of the wake-up signal associated with the first signal;

[0331] Determine the transmission parameters of the activation signal used to activate the second signal to be transmitted on demand, such as beam information, parameters for power calculation, and parameters for path loss estimation.

[0332] Send the wake-up signal associated with the first signal;

[0333] Send an activation signal to activate the second signal for on-demand transmission;

[0334] Select a second frequency domain resource associated with the first signal;

[0335] Detect the signal on a second frequency domain resource associated with the first signal, such as always on SSB or OD-SSB;

[0336] Determine the configuration information of the signal (e.g., always on SSB or OD-SSB) on the second frequency domain resource associated with the first signal, such as the DMRS configuration of the signal;

[0337] Determine the configuration information of the second signal on the second frequency domain resource associated with the first signal, such as the DMRS configuration of the second signal.

[0338] Optionally, the wake-up signal or activation signal can be configured by the first frequency domain resource where the first signal is located.

[0339] Optionally, determining the DMRS configuration of the signal on the second frequency domain resource associated with the first signal may include using the DMRS configuration of the first signal as the DMRS configuration of the signal on the second frequency domain resource, for example, demodulating the PBCH in the signal on the second frequency domain resource according to the DMRS sequence in the first signal.

[0340] Optionally, determining the DMRS configuration of the second signal on the second frequency domain resource associated with the first signal may include using the DMRS configuration of the first signal as the DMRS configuration of the second signal on the second frequency domain resource, for example, demodulating the PBCH in the second signal on the second frequency domain resource according to the DMRS sequence in the first signal.

[0341] Optionally, the first device may perform the first operation if the measured value of the first signal is below a certain threshold. A measured value below the threshold indicates poor detection performance of the first signal. Therefore, it is necessary to trigger the transmission of a signal (or a second signal) on the second frequency domain resource. The sequence group corresponding to the reference signal sequence contained in the second signal has fewer candidate reference signal sequences compared to the sequence group corresponding to the reference signal sequence contained in the first signal. This allows the first device to successfully detect the reference signal sequence in the second signal, accurately demodulate the system message carried by the PBCH in the second signal, and smoothly complete the random access procedure.

[0342] In the above embodiments 1 and 2, it was explained that corresponding sequence groups can be set according to at least some of the signals in the first signal or according to the type of the first signal to improve the detection performance of the reference signal sequence.

[0343] The following describes another implementation method for improving the detection performance of the reference signal sequence provided by the embodiments of this application, with reference to Embodiment 5. It should be noted that Embodiment 5 can be implemented alone, or it can be implemented in combination with at least one of the aforementioned Embodiments 1-4, and this application does not limit it in this regard.

[0344] Example 5

[0345] In this embodiment 5, the detection capability of the first device for the first signal and / or the detection capability requirement of the second device for the first device to detect the first signal can be introduced. For example, in embodiment 1, the number of candidate reference signal sequences in the sequence group used by different terminal types to detect the first signal can be related to the detection capability. As another example, in embodiment 2, the detection capability requirements for different types of first signals can be defined, and only terminals that meet the requirements can receive this type of first signal.

[0346] In some embodiments of this application, the method 200 further includes:

[0347] The first device reports its detection capability for the first signal to the second device.

[0348] That is, the terminal can report its detection capability of the first signal to the network-side device, such as the detection capability of the reference signal sequence in the first signal.

[0349] In some embodiments, the detection capability includes, but is not limited to, at least one of the following:

[0350] The detection time of the synchronization sequence (e.g., PSS and / or SSS) in the first signal supported by the first device;

[0351] The detection time of the first index corresponding to the first signal supported by the first device;

[0352] The first device supports the detection of the maximum number of candidate reference signal sequences on which the reference signal sequence in the first signal is based;

[0353] The receiving bandwidth of the first signal supported by the first device;

[0354] The bandwidth type of the first signal supported by the first device;

[0355] The first device supports the frequency range of the first signal.

[0356] Optionally, this detection capability can be used to determine the number of candidate reference signal sequences included in the at least one sequence group.

[0357] For example, narrowband terminals have poor detection capabilities, so the number of candidate reference signal sequences used by the narrowband terminal to detect the reference signal sequence in the first signal can be related to the narrowband terminal's capabilities. Broadband terminals, on the other hand, have superior detection capabilities, so the number of candidate reference signal sequences used by the broadband terminal to detect the reference signal sequence in the first signal can be related to the broadband terminal's capabilities. For instance, the number of candidate reference signal sequences used by the narrowband terminal to detect the reference signal sequence in the first signal can be less than the number used by the broadband terminal; that is, a smaller number of candidate reference signal sequences are configured for the narrowband terminal's reference signal sequence detection, while a larger number are configured for the broadband terminal's reference signal sequence detection.

[0358] For example, when the second device supports multiple types of first signals, the detection capability requirements (e.g., the number of candidate reference signal sequences) for different types of first signals can be defined. The number of candidate reference signal sequences for reference signal sequences in the first type of first signal can be related to the detection capability requirements of the first type of first signal, and the number of candidate reference signal sequences for reference signal sequences in the second type of first signal can be related to the detection capability requirements of the second type of first signal.

[0359] In some embodiments of this application, the method 200 further includes:

[0360] The first device receives from the second device the second device's requirement for the first device to detect the first signal.

[0361] Optionally, the detection capability requirement can be predefined, or it can be that the first device reports its own detection capability to the second device, and the second device agrees on the detection capability requirement. When the first device's detection capability can meet the second device's detection capability requirement, the first device detects the first signal sent by the second device, thus ensuring the detection performance of the first signal. For example, the first device can choose to camp on a cell where its own detection capability meets the network side's detection capability requirement. In this way, when the first device detects the first signal on that cell, it can ensure the detection performance of the first signal.

[0362] In some embodiments, the detection capability requirement includes at least one of the following:

[0363] The detection time requirement of the synchronization sequence in the first signal;

[0364] The detection time requirement for the first index of the first signal;

[0365] The first device detects the number of candidate reference signal sequences on which the reference signal sequence in the first signal is based;

[0366] The bandwidth requirement for the first device to receive the first signal;

[0367] The bandwidth type requirement for the first device to receive the first signal;

[0368] The frequency range requirement for the first device to receive the first signal.

[0369] Optionally, the detection capability of the first device meeting the detection capability requirements of the second device may include, but is not limited to, at least one of the following:

[0370] The detection time of the synchronization sequence in the first signal supported by the first device meets the detection time requirements of the second device for the synchronization sequence in the first signal.

[0371] The detection time of the first index of the first signal supported by the first device meets the detection time requirement of the second device for the first index of the first signal;

[0372] The maximum number of candidate reference signal sequences that the first device can support for detection meets the requirements of the second device for the number of candidate reference signal sequences.

[0373] The receiving bandwidth of the first signal supported by the first device meets the bandwidth requirements of the second device for the first device to receive the first signal.

[0374] The bandwidth type of the first signal supported by the first device meets the bandwidth type requirements of the second device for the first device to receive the first signal;

[0375] The frequency domain range of the first signal supported by the first device meets the frequency domain range requirements of the second device for the first signal received by the first device.

[0376] In some embodiments, the detection capability requirement is related to at least one of the following:

[0377] Multiple receiving bandwidths of the first signal;

[0378] Terminals with multiple communication modes;

[0379] Terminals with multiple capabilities or a combination of multiple capabilities;

[0380] Multiple reference signal identifiers or multiple reference signal group identifiers;

[0381] Multiple transmission frequency bands;

[0382] Multiple frequency ranges;

[0383] Multiple power ratings;

[0384] Multiple frequency domain resources;

[0385] Is it a carrier aggregation (CA) scenario or a multi-carrier scenario?

[0386] Multiple first signal cycles;

[0387] Is the first signal a first signal sent on demand?

[0388] That is, the detection capability requirements of the second device for the first signal can be determined or defined based on one or more of the above factors.

[0389] For example, corresponding detection capability requirements are defined for different receiving bandwidths of the first signal.

[0390] Optionally, the terminals using multiple communication modes may include, but are not limited to, low-power communication mode terminals and high-power communication mode terminals. The detection performance of the first signal may differ between terminals using different communication modes; therefore, corresponding detection capability requirements can be defined for each terminal using different communication modes, which is beneficial for improving the detection performance of the first signal for terminals using different communication modes.

[0391] Optionally, the detection performance of the first signal of a terminal with multiple capabilities or a combination of multiple capabilities may be different. Therefore, different detection capability requirements can be defined for terminals with different capabilities or different combinations of capabilities, which is beneficial to improving the detection performance of the first signal of terminals with different capabilities or different combinations of capabilities.

[0392] Optionally, the multiple reference signal identifiers can be multiple DMRS identifiers or beam identifiers, and the multiple reference signal group identifiers can be multiple DMRS group identifiers or beam group identifiers. The transmission power of the first signal under different beams may be different, and the detection performance of the corresponding first signal may also be different. Therefore, the corresponding detection capability requirements can be defined for different beams or beam groups, which is beneficial to improving the detection performance of the first signal.

[0393] Optionally, defining corresponding detection capability requirements for different transmission bandwidths can help improve the detection performance of the first signal with different transmission bandwidths.

[0394] Optionally, defining corresponding detection capability requirements for different frequency ranges can help improve the detection performance of the first signal in different frequency ranges.

[0395] Optionally, different detection capability requirements can be defined for different power levels, which is beneficial to improving the detection performance of the first signal at different power levels.

[0396] Optionally, defining corresponding detection capability requirements for different frequency domain resources can help improve the detection performance of the first signal on different frequency domain resources.

[0397] Optionally, defining corresponding detection capability requirements for CA or multi-carrier scenarios can help improve the detection performance of the first signal in CA or multi-carrier scenarios.

[0398] Optionally, defining corresponding detection capability requirements for different periods of the first signal can help improve the detection performance of the first signal in different periods.

[0399] Optionally, based on the type of the first signal, or whether the first signal is a signal triggered on demand, corresponding detection capability requirements can be defined, which is beneficial to improving the detection performance of different types of first signals.

[0400] The preferred embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this application, various simple modifications can be made to the technical solutions of this application, and these simple modifications all fall within the protection scope of this application. For example, the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this application will not describe the various possible combinations separately. Furthermore, various different embodiments of this application can also be arbitrarily combined, as long as they do not violate the spirit of this application, they should also be considered as the content disclosed in this application.

[0401] In summary, in some implementations, sequence groups corresponding to different parts of the first signal can be configured or predefined. In this way, when the first device performs reference signal sequence detection based on different parts of the first signal, it can perform reference signal sequence detection based on the corresponding sequence groups, which is beneficial to improving the detection performance of the reference signal sequence.

[0402] In other implementations, sequence groups corresponding to different types of first signals can be configured or predefined. In this way, the first device can select the corresponding sequence group based on the type of the first signal to perform reference signal sequence detection on the first signal, which is beneficial to improving the detection performance of the reference signal sequence.

[0403] In some other implementations, reference signal sequence detection based on different parts of the first signal can be configured or predefined to correspond to a certain number of candidate reference signal sequences. In this way, when the first device can perform reference signal sequence detection based on different parts of the first signal, it can be based on the corresponding number of candidate reference signal sequences, which is beneficial to meet the detection capabilities of reference signal sequences for different terminal types and improve the detection performance of reference signal sequences.

[0404] In some other implementations, the reference signal sequence detection of different types of first signals can be configured or predefined to correspond to a corresponding number of candidate reference signal sequences. In this way, when the first device can perform reference signal sequence detection on different types of first signals, it can be based on the corresponding number of candidate reference signal sequences, which is beneficial to improving the reference signal sequence detection performance of different types of first signals.

[0405] In some other implementations, the first device may determine the first index and / or time-related information corresponding to the first signal based on a determined reference signal sequence and / or second information.

[0406] In some implementations, the second device can indicate to the first device the correlation between signals on different frequency domain resources (e.g., a first signal on a first frequency domain resource and a second signal on a second frequency domain resource), such as the correlation of reference signal sequences. For example, the reference signal sequence of the second signal is determined based on the first signal. Thus, the first signal may include the reference signal sequence, while the second signal may not. The first device can perform reference signal sequence detection and channel estimation on the first signal without needing to perform reference signal sequence detection and channel estimation on the second signal. In this case, the PBCH in the second signal can be demodulated using the channel estimated from the reference signal sequence in the first signal, saving the resources occupied by the reference signal sequence and improving resource utilization.

[0407] In some implementations, the first device reports its detection capability for the first signal to the second device. The second device can then send a request for the first device's detection capability for the first signal. In this way, if the first device's detection capability meets the second device's requirement, the first device can detect the first signal sent by the second device, ensuring the detection performance of the first signal. For example, the first device can choose to camp on a cell where its detection capability meets the network's detection capability requirements. This ensures the detection performance of the first signal when the first device detects it in that cell.
