Description

Technical Field

[0001] This disclosure relates to the field of communications, and in particular to methods and apparatus for configuring DMRS signal formats, generating DMRS signals, and storage media. Background Technology

[0002] 3GPP (3rd Generation Partnership Project) Release 17 (R17) proposed a joint channel to enhance the coverage of PUSCH (Physical Uplink Shared Channel). Meanwhile, bundling DMRS (Demodulation Reference Signal) with cross-PUCCH (Physical Uplink Control Channel) is considered a potential solution to enhance PUCCH coverage.

[0003] Both schemes specify the binding granularity of DMRS symbols and require that power consistency and phase continuity be guaranteed within a certain time window. This requires that the power of the terminal cannot change and the phase must be continuous within the binding time window. At the same time, the DMRS pattern on each slot or repetition will also affect the joint channel estimation performance.

[0004] In a joint channel estimation scheme with DMRS binding, using fewer DMRS formats can save more resources and reduce the data transmission rate. However, if the design goal is to achieve uniform distribution of DMRS, then the location and number of DMRS need to be uniform in order to achieve the best channel estimation performance.

[0084] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0085] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The singular forms “a,” “the,” and “the” as used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0086] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0087] This disclosure provides two schemes for configuring DMRS signal formats and generating DMRS signals. Both schemes are applicable to any scenario requiring DMRS binding, and optionally may include, but are not limited to, scenarios involving joint channel estimation via DMRS binding.

[0088] In the first approach, the protocol stipulates or the base station configures a preset time window to allow the maximum number of symbols that the DMRS signal can occupy. The base station or the terminal determines the number of symbols between two adjacent DMRS signal packets, and the terminal generates DMRS signals with interval distribution according to the number of symbols between them.

[0089] The first option can further include the following four scenarios:

[0090] In the first scenario, the base station configures the maximum number of symbols M for the terminal, and the terminal needs to calculate the number of interval symbols L itself.

[0091] In the second scenario, the maximum number of symbols M can be agreed upon by agreement, and the terminal needs to calculate the number of symbols in the interval L.

[0092] In the third scenario, the maximum number of symbols M can be agreed upon by agreement, and the base station will instruct the terminal after determining the number of interval symbols L.

[0093] In the fourth scenario, the base station configures the maximum number of symbols M and the number of interval symbols L for the terminal.

[0094] The four situations mentioned above will be described in detail below.

[0095] In the first scenario, the base station configures the maximum number of symbols M for the terminal, and the terminal needs to calculate the number of interval symbols L itself.

[0096] This disclosure provides a method for configuring a DMRS signal format, referring to... Figure 1 As shown, Figure 1 This is a flowchart illustrating a method for configuring a DMRS signal format according to an embodiment, which can be used in a base station. The method may include the following steps:

[0097] In step 101, the terminal is configured with the maximum number of symbols that the DMRS signal is allowed to occupy within a preset time window. The preset time window includes multiple transmission opportunities for the physical channel used for DMRS binding.

[0098] In this embodiment of the disclosure, the physical channel includes, but is not limited to, any one of the following: PUSCH, PUCCH (Physical Uplink Control Channel), PDSCH (Physical Downlink Shared Channel), and PDCCH (Physical Downlink Control Channel). Multiple transmission opportunities can be used to indicate multiple repeated transmission opportunities corresponding to the same physical channel when physical channel enhancement is performed.

[0099] In the above embodiments, the base station can configure the maximum number of symbols for the terminal, and the terminal can determine the number of symbols between two adjacent DMRS signal packets when generating DMRS signals, thereby generating DMRS signals that satisfy the interval distribution. This can reduce the DMRS density, thereby providing more locations for data transmission, and at the same time, it can make the DMRS as evenly distributed as possible in different physical channel transmission times, which helps to maintain power consistency and phase continuity, and also helps to improve channel estimation performance.

[0100] In some alternative embodiments, the base station can configure the maximum number of symbols for the terminal via target signaling, wherein the target signaling includes, but is not limited to, physical layer or higher layer signaling.

[0101] Specifically, the base station can directly configure the maximum number of symbols for the terminal by displaying an instruction.

[0102] Reference Figure 2 As shown, Figure 2 This is a flowchart illustrating a method for configuring a DMRS signal format according to an embodiment, which can be used in a base station. The method may include the following steps:

[0103] In step 201, the terminal is configured with the value corresponding to the maximum number of symbols via target signaling.

[0104] In this disclosure, the target signaling includes, but is not limited to, at least one of the following: RRC (Radio Resource Control) signaling, MAC-CE (Media Access Control-Control Element) signaling, and DCI (Downlink Control Information).

[0105] In one possible implementation, the base station can send the maximum number of symbols to the terminal by reusing the existing information field of the target signaling.

[0106] In another possible implementation, the base station can send the maximum symbol count value to the terminal by carrying the value of the maximum symbol count in a newly added information field in the target signaling.

[0107] In the above embodiments, the base station can send the maximum number of symbols to the terminal through target signaling in a display indication manner, which is simple to implement and highly available.

[0108] Alternatively, the base station can also configure associated parameter values ​​for the terminal to determine the value corresponding to the maximum number of symbols through implicit indication.

[0109] Reference Figure 3 As shown, Figure 3 This is a flowchart illustrating a method for configuring a DMRS signal format according to an embodiment, which can be used in a base station. The method may include the following steps:

[0110] In step 301, the target signaling is used to configure the terminal with an associated parameter value for determining the numerical value corresponding to the maximum number of symbols.

[0111] In this embodiment of the disclosure, the target signaling includes, but is not limited to, at least one of the following: RRC signaling, MAC CE signaling, and DCI.

[0112] The associated parameter values ​​include, but are not limited to, at least one of the following: the number of the plurality of transmission opportunities included in the preset time window, the total number of symbols included in the preset time window, and the total number of time slots included in the preset time window.

[0113] In the above embodiments, the base station can implicitly configure association parameter values ​​for the terminal. Subsequently, the terminal can calculate the maximum number of symbols based on the association parameter values ​​configured by the base station, which is simple to implement and highly available.

[0114] In some alternative embodiments, refer to Figure 4 As shown, Figure 4This is a flowchart illustrating a method for configuring a DMRS signal format according to an embodiment, which can be used in a base station. The method may include the following steps:

[0115] In step 401, the terminal is configured with the maximum number of symbols that the DMRS signal is allowed to occupy within a preset time window. The preset time window includes multiple transmission opportunities for the physical channel used for DMRS binding.

[0116] In step 402, the indication granularity corresponding to the maximum number of symbols is configured for the terminal.

[0117] In this embodiment of the disclosure, while configuring the maximum number of symbols for the terminal through target signaling, the base station can also configure the indication granularity corresponding to the maximum number of symbols for the terminal through the same target signaling. The indication granularity corresponding to the maximum number of symbols refers to the correspondence between the maximum number of symbols and at least one of the following: terminal, terminal service type, physical channel format, and preset time window size.

[0118] Optionally, the granularity of the indication corresponding to the maximum number of symbols may include, but is not limited to, at least one of the following:

[0119] All terminals within the cell, different terminal groups, designated terminals, different physical uplink control channel (PUCCH) formats for designated terminals, different service types for designated terminals, and different preset time window sizes for designated terminals.

[0120] Taking the maximum symbol count as an indication granularity corresponding to all terminals within a cell as an example, if the base station configures a maximum symbol count M1 for a terminal, then M1 applies to all terminals within that cell. Taking the maximum symbol count as an indication granularity corresponding to a specific terminal as another example, the maximum symbol count M2 configured by the base station only applies to that specific terminal, while the maximum symbol count M3 for other terminals can be different from M1. The meanings of other indication granularities are similar to the above examples and will not be repeated here.

[0121] In the above embodiments, the base station can configure the maximum number of symbols for the terminal, and at the same time, it can also configure the indication granularity corresponding to the maximum number of symbols for the terminal, which is more conducive to improving the channel estimation performance.

[0122] In some alternative embodiments, refer to Figure 5 As shown, Figure 5 This is a flowchart illustrating a method for configuring a DMRS signal format according to an embodiment, which can be used in a base station. The method may include the following steps:

[0123] In step 501, the terminal is configured with the maximum number of symbols allowed to be occupied by the DMRS signal within a preset time window, the preset time window including multiple transmission opportunities for the physical channel used for DMRS binding.

[0124] Optionally, in step 502, the number of consecutive DMRS symbols in each DMRS signal group within the preset time window is configured for the terminal.

[0125] In one possible implementation, the number of adjacent consecutive DMRS symbols in each DMRS signal packet within a preset time window configured by the base station for the terminal can be one or two, or more, and this disclosure does not limit this.

[0126] In another possible implementation, step 502 can be omitted, and the terminal side defaults to setting the number of adjacent consecutive DMRS symbols in each DMRS signal packet within a preset time window to one.

[0127] In the above embodiments, while configuring the maximum number of symbols allowed for the DMRS signal to occupy within a preset time window, the base station can also configure the number of adjacent consecutive DMRS symbols in each DMRS signal packet for the terminal. If the base station does not configure the number of adjacent consecutive DMRS symbols in each DMRS signal packet, the terminal can use the default value. This also achieves the goal of distributing DMRS as evenly as possible across different physical channel transmission times, which helps maintain power consistency and phase continuity, and improves channel estimation performance. Based on the base station configuring this maximum number of symbols for the terminal, this disclosure also provides a corresponding scheme for generating DMRS signals on the terminal side.

[0128] Reference Figure 6 As shown, Figure 6 This is a flowchart illustrating a method for generating a DMRS signal according to an embodiment, which can be used in a terminal. The method may include the following steps:

[0129] In step 601, based on the maximum number of symbols, the total number of symbols included in the preset time window, and the number of adjacent consecutive DMRS symbols in each DMRS signal packet, the interval number of symbols between two adjacent DMRS signal packets within the preset time window is determined.

[0130] In this embodiment of the disclosure, the maximum number of symbols is configured by the base station for the terminal.

[0131] In one possible implementation, the terminal directly receives the maximum number of symbols configured by the base station in an explicit manner.

[0132] In another possible implementation, if the base station implicitly sends the association parameter value, the terminal can calculate the value corresponding to the maximum symbol number based on the received association parameter value and the pre-determined correspondence between the association information and the maximum symbol number. The association parameter value includes, but is not limited to, at least one of the following: the number of the plurality of transmission opportunities included in the preset time window, the total number of symbols included in the preset time window, and the total number of time slots included in the preset time window.

[0133] For example, if the associated parameter value is the total number of symbols included in the preset time window, the total number of symbols is 32, and the preset correspondence is the ratio between the total number of symbols and the maximum number of symbols is 8:1, then the terminal can determine that the maximum number of symbols is 4.

[0134] In this embodiment of the disclosure, the terminal can calculate the total number of symbols based on the binding granularity N of the DMRS corresponding to the preset time window indicated by the base station. Here, the binding granularity N of the DMRS means binding N transmission opportunities of the physical channel.

[0135] For example, if the terminal has determined that each transmission opportunity occupies 7 consecutive time-domain symbols and the DMRS binding granularity is 4, then the terminal can calculate the total number of symbols as 4 × 7 = 28.

[0136] In this embodiment of the disclosure, the number of DMRS symbols in a DMRS signal packet can be configured by the base station for the terminal, or the terminal can default to setting the number of adjacent consecutive DMRS symbols in each DMRS signal packet to 1.

[0137] In one possible implementation, if the base station configures the number of consecutive DMRS symbols in each DMRS signal packet to be 1, or if the terminal defaults to setting the number of consecutive DMRS symbols in each DMRS signal packet to be 1, the terminal can calculate the interval symbol number L according to the following formula:

[0138] L = Total number of symbols / M (Formula 1)

[0139] Here, M refers to the maximum number of signs.

[0140] For example, if the base station configures M for the terminal to be 4, each transmission opportunity occupies 7 consecutive time domain symbols, and the DMRS binding granularity is 4, then the number of interval symbols L can be calculated as 7 according to the above formula 1.

[0141] Optionally, if the value calculated by the terminal using Formula 1 is not an integer, it can be rounded up or down, and this disclosure does not limit this.

[0142] In another possible implementation, the base station configures the terminal with the number S of adjacent consecutive DMRS symbols in each DMRS signal packet, where S is a value greater than or equal to 2. Then, the terminal can calculate the interval symbol number L using the following formula:

[0143] L = (Total number of symbols × S) ÷ M Formula 2

[0144] Assuming S is 2, each transmission opportunity occupies 7 consecutive time-domain symbols, the DMRS binding granularity is 4, and M is 6, then L calculated using Formula 2 is 9 (rounded down).

[0145] In step 602, within the preset time window, based on the maximum number of symbols, a DMRS signal is generated that is distributed according to the interval number of symbols and satisfies the number of adjacent consecutive DMRS symbols in each DMRS signal group.

[0146] In this embodiment of the disclosure, the terminal can place S DMRS signals within a preset time window according to the number of interval symbols. For example, if the base station configures a maximum number of symbols for the terminal of 6, S defaults to 1, the DMRS binding granularity is 4, each transmission opportunity occupies 7 consecutive time symbols, and the terminal calculates an interval symbol number of 4, then the format of the DMRS signal generated by the terminal refers to... Figure 7 As shown, the terminal places a DMRS signal every 4 symbols.

[0147] It should be noted that the total number of DMRS signals generated by the terminal within the preset time window should be less than or equal to the maximum number of symbols.

[0148] In the above embodiments, the terminal determines the number of symbols between two adjacent DMRS signal packets based on the maximum number of symbols configured by the base station, the total number of symbols included in the preset time window, and the number of adjacent consecutive DMRS symbols in each DMRS signal packet. Then, it generates DMRS signals at intervals within the preset time window. This can reduce the DMRS density, thereby providing more locations for data transmission. At the same time, it can make the DMRS as evenly distributed as possible in different physical channel transmission times, which helps to maintain power consistency and phase continuity, and also helps to improve channel estimation performance.

[0149] In the second scenario, the maximum number of symbols M can be agreed upon by agreement, and the terminal needs to calculate the number of symbols in the interval L.

[0150] In this scenario, the base station does not need to configure a maximum number of symbols for the terminal. The terminal can directly determine the maximum number of symbols according to the protocol. Furthermore, the terminal can determine the interval symbol number between two adjacent DMRS signal packets within the preset time window based on the maximum number of symbols agreed upon in the protocol, the total number of symbols included in the preset time window, and the number of adjacent consecutive DMRS symbols in each DMRS signal packet. The method for determining the interval symbol number is the same as in step 601 above, and will not be repeated here.

[0151] After determining the number of interval symbols, the terminal can generate a DMRS signal with interval distribution in the manner described in step 602 above. The generation method is the same as in step 602, and will not be repeated here.

[0152] In the above embodiments, the terminal determines the maximum number of symbols based on the protocol agreement, and determines the number of symbols between two adjacent DMRS signal packets based on the maximum number of symbols, the total number of symbols included in the preset time window, and the number of adjacent consecutive DMRS symbols in each DMRS signal packet. Then, it generates DMRS signals at intervals within the preset time window. This can reduce the DMRS density, thereby providing more space for data transmission. At the same time, it can make the DMRS as evenly distributed as possible in different physical channel transmission times, which helps to maintain power consistency and phase continuity, and also helps to improve channel estimation performance.

[0153] In the third scenario, the maximum number of symbols M can be agreed upon by agreement, and the base station will instruct the terminal after determining the number of interval symbols L.

[0154] Reference Figure 8 As shown, Figure 8 This is a flowchart illustrating a method for configuring a DMRS signal format according to an embodiment, which can be used in a base station. The method may include the following steps:

[0155] In step 801, the terminal is configured with the number of symbols between two adjacent DMRS signal packets when generating DMRS signals within a preset time window. The preset time window includes multiple transmission opportunities for the physical channel used for DMRS binding.

[0156] In the above embodiments, the base station can directly determine the number of interval symbols and send it to the terminal. The terminal can then generate a DMRS signal with a distributed interval based on the number of interval symbols. This can reduce the DMRS density, thereby providing more locations for data transmission. At the same time, it can make the DMRS as evenly distributed as possible in different physical channel transmission times, which helps to maintain power consistency and phase continuity, and also helps to improve channel estimation performance.

[0157] In some alternative embodiments, refer to Figure 9 As shown, Figure 9This is a flowchart illustrating a method for configuring a DMRS signal format according to an embodiment, which can be used in a base station. The method may include the following steps:

[0158] In step 901, the number of interval symbols is determined based on the total number of symbols included in the preset time window, the maximum number of symbols allowed for the DMRS signal to occupy within the preset time window as agreed in the protocol, and the number of adjacent consecutive DMRS symbols in each DMRS signal group.

[0159] In this embodiment of the disclosure, the base station can calculate the number of interval symbols L according to the above formula 1 or formula 2. The specific calculation method is the same as the method of calculating L in step 601, and will not be repeated here.

[0160] In step 902, the number of interval symbols is sent via target signaling.

[0161] In this embodiment of the disclosure, the target signaling includes, but is not limited to, at least one of the following: RRC signaling, MAC CE signaling, and DCI.

[0162] In one possible implementation, the base station can send the value of the number of interval symbols to the terminal by reusing the existing information field of the target signaling.

[0163] In another possible implementation, the base station can send the value of the number of interval symbols to the terminal by carrying the value of the number of interval symbols in a newly added information field in the target signaling.

[0164] In the above embodiments, the base station can determine the interval symbol number based on the maximum number of symbols agreed upon in the protocol, the total number of symbols included in the preset time window, and the number of adjacent consecutive DMRS symbols in each DMRS signal packet, and then send this information to the terminal. The terminal can directly generate an interval-distributed DMRS signal based on this interval symbol number. This reduces the DMRS density, thereby providing more locations for data transmission, and allows the DMRS to be distributed as evenly as possible across different physical channel transmission times, which helps maintain power consistency and phase continuity, and also helps improve channel estimation performance.

[0165] In some alternative embodiments, refer to Figure 10 As shown, Figure 10 This is a flowchart illustrating a method for configuring a DMRS signal format according to an embodiment, which can be used in a base station. The method may include the following steps:

[0166] In step 1001, the terminal is configured with the number of symbols between two adjacent DMRS signal packets when generating DMRS signals within a preset time window. The preset time window includes multiple transmission opportunities for the physical channel used for DMRS binding.

[0167] In step 1002, the indicator granularity corresponding to the number of interval symbols is configured for the terminal.

[0168] In this embodiment of the disclosure, while configuring the number of interval symbols for the terminal through target signaling, the base station can also configure the indication granularity corresponding to the number of interval symbols for the terminal through the same target signaling. The indication granularity corresponding to the number of interval symbols refers to the correspondence between the number of interval symbols and at least one of the following: terminal, terminal service type, physical channel format, and preset time window size.

[0169] Optionally, the granularity of the indication corresponding to the number of interval symbols may include, but is not limited to, at least one of the following:

[0170] All terminals within the cell, different terminal groups, designated terminals, different physical uplink control channel (PUCCH) formats for designated terminals, different service types for designated terminals, and different preset time window sizes for designated terminals.

[0171] Taking the interval symbol number as an example, where the indication granularity corresponds to different service types of a specified terminal, if the base station configures an interval symbol number L1 for a terminal, then L1 is for service type 1 of the specified terminal. The interval symbol number L2 corresponding to service type 2 of the specified terminal can be different from L1. The meanings of other indication granularities are similar to the above example and will not be repeated here.

[0172] In the above embodiments, the base station can configure the number of interval symbols for the terminal, and at the same time, it can also configure the indication granularity corresponding to the number of interval symbols for the terminal, which is more conducive to improving the channel estimation performance.

[0173] In some alternative embodiments, refer to Figure 11 As shown, Figure 11 This is a flowchart illustrating a method for configuring a DMRS signal format according to an embodiment, which can be used in a base station. The method may include the following steps:

[0174] In step 1101, the terminal is configured to specify the number of symbols between two adjacent DMRS signal packets when generating DMRS signals within a preset time window. The preset time window includes multiple transmission opportunities for the physical channel used for DMRS binding.

[0175] In step 1102, the number of consecutive DMRS symbols in each DMRS signal packet is configured for the terminal.

[0176] In one possible implementation, the base station can also configure the terminal with the number S of consecutive DMRS symbols in each DMRS signal packet. The value of S can be a positive integer, such as 1 or 2, or more.

[0177] In another possible implementation, step 1102 can be omitted, and the terminal side defaults to a value of 1 for S.

[0178] In the above embodiments, while configuring the number of interval symbols for the terminal, the base station can also configure the number of adjacent consecutive DMRS symbols in each DMRS signal packet for the terminal. If the base station does not configure the number of adjacent consecutive DMRS symbols in each DMRS signal packet, the terminal side can use the default value. This also achieves the goal of making DMRS as evenly distributed as possible in different physical channel transmission times, which helps to maintain power consistency and phase continuity, and helps to improve channel estimation performance.

[0179] Accordingly, when the base station configures the number of interval symbols for the terminal, the terminal can generate DMRS signals in the following ways.

[0180] Reference Figure 12 As shown, Figure 12 This is a flowchart illustrating a method for generating a DMRS signal according to an embodiment, which can be used in a terminal. The method may include the following steps:

[0181] In step 1201, the number of interval symbols between two adjacent DMRS signal packets within a preset time window configured by the base station for the terminal is received. The preset time window includes multiple transmission opportunities for the physical channel used for DMRS binding.

[0182] In this embodiment of the disclosure, after the base station determines the number of interval symbols L, it can directly send it to the terminal.

[0183] In step 1202, within the preset time window, based on the maximum number of symbols allowed for the DMRS signal to occupy within the preset time window as agreed in the protocol, the DMRS signal is generated according to the interval symbol number distribution and satisfies the number of adjacent consecutive DMRS symbols in each DMRS signal group.

[0184] In this embodiment of the disclosure, the number of adjacent consecutive DMRS symbols in each DMRS signal packet can be configured by the base station for the terminal, or the terminal can default to setting the number of adjacent consecutive DMRS symbols in each DMRS signal packet to 1.

[0185] Within a preset time window, the terminal can generate a DMRS signal with an interval distribution that satisfies the number of consecutive adjacent DMRS symbols in each DMRS signal packet, according to the number of interval symbols sent by the base station. For example... Figure 7 As shown. Furthermore, the total number of DMRS signals generated by the terminal within the preset time window is less than or equal to the maximum number of symbols agreed upon in the protocol.

[0186] In the above embodiments, the terminal can generate a DMRS signal with an interval distribution that satisfies the number of adjacent consecutive DMRS symbols in each DMRS signal packet, based on the number of interval symbols configured by the base station. This reduces DMRS density, thereby providing more space for data transmission, and allows DMRS to be distributed as evenly as possible across different physical channel transmission times, helping to maintain power consistency and phase continuity, and also improving channel estimation performance.

[0187] In the fourth scenario, the base station configures the maximum number of symbols M and the number of interval symbols L for the terminal.

[0188] In this embodiment of the disclosure, the base station can configure the maximum number of symbols M for the terminal using the method described in the first case. Simultaneously, the base station can also configure the interval symbol number L for the terminal using the method described in the third case.

[0189] The base station can send the maximum number of symbols M and the number of interval symbols L configured for the terminal simultaneously to the terminal through target signaling.

[0190] In one possible implementation, the base station may also configure the indication granularity corresponding to the maximum number of symbols for the terminal, and / or configure the indication granularity corresponding to the interval number of symbols for the terminal.

[0191] In another possible implementation, the base station can also configure the number of adjacent consecutive DMRS symbols in each DMRS signal packet for the terminal. This can be configured by the base station for the terminal, or the terminal can default to setting the number of adjacent consecutive DMRS symbols in each DMRS signal packet to 1.

[0192] Within the preset time window, the terminal directly generates a DMRS signal based on the maximum number of symbols L configured by the base station. This DMRS signal is distributed according to the specified interval symbol number and satisfies the requirement of consecutive DMRS symbols in each DMRS signal packet. The interval symbol number is also configured by the base station for the terminal. The method by which the terminal generates the DMRS signal is the same as that in the third scenario described above, and will not be repeated here.

[0193] In the above embodiments, the base station can simultaneously configure the maximum number of symbols and the number of interval symbols. The terminal, based on the base station configuration, generates a DMRS signal that is distributed according to the specified number of interval symbols and satisfies the requirement of consecutive DMRS symbols in each DMRS signal packet. This reduces DMRS density, providing more space for data transmission, and allows DMRS to be distributed as evenly as possible across different physical channel transmission times, helping to maintain power consistency and phase continuity, and improving channel estimation performance.

[0194] After introducing the first scheme described above, this disclosure also provides a second scheme for configuring the DMRS signal format and generating the DMRS signal.

[0195] The second approach involves a protocol or base station configuration that limits the maximum number of symbols that DMRS signals can occupy within a preset time window. The base station configuration or protocol also generates corresponding distribution rules for the location and number of DMRS signals within each transmission window. The terminal then generates the corresponding DMRS signals according to these distribution rules.

[0196] In some optional embodiments, the base station can configure the maximum number of symbols for the terminal. The base station can explicitly configure the value corresponding to the maximum number of symbols for the terminal via target signaling. Alternatively, the base station can configure an association parameter value for the terminal via target signaling to determine the value corresponding to the maximum number of symbols, and the terminal determines the value corresponding to the maximum number of symbols based on this association parameter value. The configuration method is the same as the method used by the base station to configure the maximum number of symbols for the terminal in the above embodiments, and will not be repeated here.

[0197] Furthermore, the base station can also configure the indication granularity corresponding to the maximum number of symbols for the terminal. Optionally, the indication granularity corresponding to the maximum number of symbols may include, but is not limited to, at least one of the following: all terminals in the cell, different terminal groups, designated terminals, different physical uplink control channel (PUCCH) formats of designated terminals, different service types of designated terminals, and different preset time window sizes of designated terminals.

[0198] In this embodiment of the disclosure, the maximum number of symbols can also be directly agreed upon by the protocol, without the base station needing to configure it for the terminal.

[0199] In some alternative embodiments, the base station may configure a first distribution format for the terminal to generate the DMRS signal within the preset time window, the first distribution format being used at least to indicate the location of the DMRS signal distribution within the preset time window.

[0200] Reference Figure 13A As shown, Figure 13A This is a flowchart illustrating a method for configuring a DMRS signal format according to an embodiment, which can be used in a base station. The method may include the following steps:

[0201] In step 1301, a first distribution format is configured for the terminal to generate the DMRS signal within a preset time window. The first distribution format is used to indicate at least the location of the DMRS signal within the preset time window, which includes multiple transmission opportunities for physical channels used for DMRS binding.

[0202] In one possible implementation, the first step format can be used to indicate the middle position of a plurality of consecutive symbols occupied by the terminal in each transmission opportunity included in the preset time window, with at least one of the DMRS symbols continuously distributed, for example... Figure 13B or Figure 13C As shown.

[0203] In another possible implementation, the first distribution format can be used to indicate the start and end positions of multiple consecutive symbols occupied by the terminal in each transmission window included in the preset time window, and to equally distribute at least one of the DMRS symbols, for example... Figure 13D As shown in the above embodiments, the base station can configure the terminal to generate a first distribution format of DMRS signals within a preset time window, so that the terminal generates DMRS signals according to the first distribution format. This can reduce the DMRS density, thereby providing more locations for data transmission, and at the same time, allow the DMRS to be distributed as evenly as possible at different physical channel transmission times, which helps to maintain power consistency and phase continuity, and also helps to improve channel estimation performance.

[0204] In some optional embodiments, the base station can send a first bit value to the terminal via target signaling to indicate the first distribution rule. For example, when the first bit value is 1, it indicates the middle position of multiple consecutive symbols occupied by the terminal in each transmission opportunity within the preset time window, and at least one of the DMRS symbols is continuously distributed. When the first bit value is 0, it indicates the start and end positions of multiple consecutive symbols occupied by the terminal in each transmission opportunity within the preset time window, and at least one of the DMRS symbols is equally distributed. The reverse is also true.

[0205] The target signaling includes, but is not limited to, at least one of the following: RRC signaling, MAC CE signaling, and DCI.

[0206] In the above embodiments, when the base station configures the first distribution format for the terminal, the base station can send a first bit value indicating the first distribution rule to the terminal through target signaling, which is simple to implement and has high availability.

[0207] In some alternative embodiments, the first distribution format described above can also be directly agreed upon by the protocol, without requiring the base station to configure the terminal.

[0208] In some alternative embodiments, the base station may also configure the terminal with a second distribution format for generating the remaining DMRS symbols to be distributed within the preset time window.

[0209] Reference Figure 14 As shown, Figure 14This is a flowchart illustrating a method for configuring a DMRS signal format according to an embodiment, which can be used in a base station. The method may include the following steps:

[0210] In step 1401, a first distribution format is configured for the terminal to generate the DMRS signal within a preset time window. The first distribution format is used to indicate at least the location of the DMRS signal within the preset time window, which includes multiple transmission opportunities for physical channels used for DMRS binding.

[0211] In step 1402, the terminal is configured with a second distribution format for generating the remaining DMRS symbols to be distributed within the preset time window.

[0212] In one possible implementation, the second distribution format instructs the terminal to sequentially distribute the remaining DMRS symbols to be distributed individually within multiple consecutive time symbols occupied by the even-numbered transmission opportunity in the preset time window. For example, if the terminal generates a DMRS signal according to the first distribution format, and there are still two remaining DMRS symbols to be distributed, then the remaining DMRS symbols can be placed in the second and fourth transmission opportunities according to the second distribution format, as shown below. Figure 15A As shown.

[0213] In another possible implementation, the second distribution format instructs the terminal to sequentially distribute the remaining DMRS symbols to be distributed individually within multiple consecutive time symbols occupied by the odd-numbered transmission opportunity in the preset time window. For example, if the terminal generates a DMRS signal according to the first distribution format, and there are still two remaining DMRS symbols to be distributed, then the remaining DMRS symbols to be distributed can be placed in the first and third transmission opportunities according to the second distribution format, as shown below. Figure 15B As shown.

[0214] In the above embodiments, it is possible to avoid distributing the remaining DMRS symbols to be distributed sequentially in the first N transmission opportunities. This allows the DMRS to be distributed as evenly as possible in different physical channel transmission opportunities, which helps to maintain power consistency and phase continuity, and also helps to improve channel estimation performance.

[0215] In some alternative embodiments, the base station can send a second bit value to the terminal via target signaling to indicate the second distribution format. For example, when the second bit value is 1, it instructs the terminal to sequentially distribute the remaining DMRS symbols to be distributed individually within the multiple consecutive time symbols occupied by the even-numbered transmission opportunity within the preset time window; when the second bit value is 0, it instructs the terminal to sequentially distribute the remaining DMRS symbols to be distributed individually within the multiple consecutive time symbols occupied by the odd-numbered transmission opportunity within the preset time window. The reverse is also true.

[0216] The target signaling includes, but is not limited to, at least one of the following: RRC signaling, MAC CE signaling, and DCI.

[0217] In the above embodiments, when the base station configures the second distribution format for the terminal, the base station can send a second bit value indicating the second distribution rule to the terminal through target signaling, which is simple to implement and highly available.

[0218] In some alternative embodiments, the second distribution format can also be directly agreed upon by the protocol, without requiring the base station to configure it for the terminal.

[0219] In some alternative embodiments, when the base station simultaneously configures the maximum number of symbols, the first distribution format, and the second distribution format for the terminal, less signaling can be used to simultaneously indicate the maximum number of symbols, the first distribution format, and the second distribution format.

[0220] In one possible implementation, the base station can transmit a third bit value of the target number via target signaling, the third bit value of the target number being used to simultaneously indicate the first distribution format, the second distribution format, and the maximum number of symbols.

[0221] Optionally, the target number can be a positive integer, such as 3. Assuming the third bit of the 3 bits is 100 and the highest bit is set to a bit value of 1, it can indicate that the maximum number of symbols in the terminal is 8. The first distribution format is to continuously distribute at least one of the DMRS symbols in the middle position of the multiple consecutive symbols occupied by each transmission opportunity included in the preset time window, and the second distribution format is to sequentially distribute the remaining DMRS symbols to be distributed individually in the multiple consecutive time symbols occupied by the even-numbered transmission opportunity in the preset time window.

[0222] The above is merely an illustrative example. Any method that simultaneously indicates at least two of the maximum number of symbols, the first distribution format, and the second step format using a small number of bit values ​​should fall within the scope of protection of this disclosure.

[0223] In the above embodiments, when the base station configures a large amount of content for the terminal, a smaller number of bit values ​​can be used to indicate at least two of the maximum number of symbols, the first distribution format, and the second step format, which saves the base station's signaling resources and has high availability.

[0224] Based on the above scheme for configuring the DMRS signal format, this disclosure also provides a corresponding scheme for generating DMRS signals.

[0225] Reference Figure 16 As shown, Figure 16 This is a flowchart illustrating a method for generating a DMRS signal according to an embodiment, which can be used in a terminal. The method may include the following steps:

[0226] In step 1601, based on the maximum number of symbols allowed to be occupied by the DMRS signal within a preset time window and the first distribution format for generating the DMRS signal within the preset time window, the DMRS signal conforming to the first distribution format is generated within the preset time window.

[0227] The first distribution format is used to indicate at least the location of the DMRS signal within the preset time window, which includes multiple transmission opportunities for the physical channel used for DMRS binding. When the terminal generates the DMRS signal with the first symbol distribution format, the number of symbols occupied by the DMRS signal is less than or equal to the maximum number of symbols.

[0228] In the above embodiments, the terminal can distribute the generated DMRS as evenly as possible across different physical channel transmission times based on the maximum number of symbols and the first distribution format used to generate the DMRS signal within the preset time window. This helps maintain power consistency and phase continuity, and also helps improve channel estimation performance.

[0229] In some optional embodiments, the terminal may receive the maximum number of symbols configured by the base station for the terminal. Specifically, the terminal may directly receive the value corresponding to the maximum number of symbols configured by the base station for the terminal, or the terminal may determine the value corresponding to the maximum number of symbols based on the association parameter values ​​configured by the base station for the terminal. The association parameter values ​​include, but are not limited to, at least one of the following: the number of the plurality of transmission opportunities included in the preset time window, the total number of symbols included in the preset time window, and the total number of time slots included in the preset time window.

[0230] Alternatively, the terminal can directly determine the maximum number of symbols based on the protocol agreement.

[0231] In some alternative embodiments, the terminal may determine the first distribution format based on the received first bit value. For example, when the first bit value is 1, the terminal determines the first distribution format as the middle position of a plurality of consecutive symbols occupied by each transmission opportunity within the preset time window, and continuously distributes at least one of the DMRS symbols. When the first bit value is 0, the terminal determines the first distribution format as the start and end positions of a plurality of consecutive symbols occupied by each transmission opportunity within the preset time window, and equally distributes at least one of the DMRS symbols. The reverse is also true.

[0232] Alternatively, the terminal can directly determine the first distribution format based on the protocol agreement.

[0233] In some alternative embodiments, refer to Figure 17 As shown, Figure 17 This is a flowchart illustrating a method for generating a DMRS signal according to an embodiment, which can be used in a terminal. The method may include the following steps:

[0234] In step 1701, based on the maximum number of symbols allowed to be occupied by the DMRS signal within a preset time window and the first distribution format for generating the DMRS signal within the preset time window, the DMRS signal conforming to the first distribution format is generated within the preset time window.

[0235] The first distribution format is used to indicate at least the location of the DMRS signal within the preset time window, which includes multiple transmission opportunities for the physical channel used for DMRS binding.

[0236] In step 1702, in response to determining that there are remaining DMRS symbols to be distributed, the remaining DMRS symbols to be distributed are generated in accordance with the second distribution format within the preset time window.

[0237] For example, with a maximum of 6 symbols, after generating DMRS signals in the middle of multiple consecutive symbols occupied during 4 transmissions according to the first distribution format, there are still 2 remaining DMRS signals to be distributed.

[0238] In one possible implementation, the terminal can determine the second distribution format based on the received second bit value. For example, if the second bit value is 1, the terminal determines the second distribution format to be to sequentially distribute the remaining DMRS symbols to be distributed individually within multiple consecutive time symbols occupied by the even-numbered transmission opportunity within the preset time window. If the second bit value is 0, the terminal determines the second distribution format to be to sequentially distribute the remaining DMRS symbols to be distributed individually within multiple consecutive time symbols occupied by the odd-numbered transmission opportunity within the preset time window. The reverse is also true.

[0239] In the above embodiments, the density of DMRS can be reduced, thereby providing more locations for data transmission. At the same time, DMRS can be distributed as evenly as possible across different physical channel transmission times, which helps maintain power consistency and phase continuity, and also helps improve channel estimation performance.

[0240] In some alternative embodiments, the terminal may determine the first distribution format, the second distribution format, and the maximum number of symbols corresponding to the received third bit value of the target number based on the correspondence between the bit value of the target number and the first distribution format, the second distribution format, and the maximum number of symbols.

[0241] For example, when the terminal receives the 3-bit third bit value 100, according to the above correspondence, the terminal determines that when the highest bit is 1, the maximum number of symbols is 8, and the first distribution format is to continuously distribute at least one of the DMRS symbols in the middle position of the multiple consecutive symbols occupied by each transmission opportunity included in the preset time window, and the second distribution format is to sequentially distribute the remaining DMRS symbols to be distributed individually in the multiple consecutive time symbols occupied by the even-numbered transmission opportunity within the preset time window.

[0242] In the above embodiments, the terminal can quickly determine the maximum number of symbols, the first distribution format, and the second distribution format configured by the base station for the terminal based on a relatively small number of received third bit values, which is simple to implement and highly available.
