For example, an uplink subband can be configured for a terminal on a downlink time slot. Then, within that downlink time slot, the terminal can use the frequency domain resources of the uplink subband for uplink communication and / or use frequency domain resources outside the uplink subband for downlink communication. However, the current method of terminals using subbands for communication has some problems. Summary of the Invention

[0033] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0034] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the present disclosure. The singular forms “a” 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.

[0035] It should be understood that although the terms first, second, third, etc., may be used to describe various information in embodiments of this disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, first information may also be referred to as second information without departing from the scope of embodiments of this disclosure, 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 a determination."

[0036] For the sake of brevity and ease of understanding, this document uses the terms "greater than" or "less than", "higher than" or "lower than" to describe size relationships. However, it will be understood by those skilled in the art that the term "greater than" also includes the meaning of "greater than or equal to", and "less than" also includes the meaning of "less than or equal to"; the term "higher than" also includes the meaning of "higher than or equal to", and "lower than" also includes the meaning of "lower than or equal to".

[0037] In one embodiment, the network device can configure a downlink subband for the terminal in the uplink time slot. If the network device can perform full-duplex communication and the terminal can perform half-duplex communication, the terminal can perform downlink communication within the downlink subband or uplink communication on frequency domain resources outside the downlink subband in the uplink time domain unit. If both the network device and the terminal can perform full-duplex communication, the terminal can perform downlink communication within the downlink subband and uplink communication on frequency domain resources outside the downlink subband in the uplink time domain unit.

[0038] In one embodiment, the network device can configure an uplink subband for the terminal in the downlink time slot. If the network device can perform full-duplex communication and the terminal can perform half-duplex communication, the terminal can perform uplink communication within the uplink subband or downlink communication on frequency domain resources outside the uplink subband in the downlink time domain unit. If both the network device and the terminal can perform full-duplex communication, the terminal can perform uplink communication within the uplink subband and downlink communication on frequency domain resources outside the uplink subband in the downlink time domain unit.

[0039] When a network device configures an uplink subband for a terminal in the downlink time slot, the terminal can perform uplink transmissions within the uplink subband, such as sending the Physical Uplink Shared Channel (PUSCH) and the PUSCH Demodulation Reference Signal (DMRS) to the network device. However, the network device can also configure some resources within the uplink subband that are not used for DMRS transmission. When resources used for DMRS transmission overlap with those not used for DMRS transmission, DMRS transmission will fail. Since DMRS is used for demodulation-related operations of PUSCH, this will degrade PUSCH transmission performance.

[0040] Figure 1This is a schematic flowchart illustrating a resource determination method according to an embodiment of the present disclosure. The resource determination method shown in this embodiment can be executed by a terminal, which includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices. The terminal can communicate with network devices, which include, but are not limited to, network devices in 4G, 5G, and 6G communication systems, such as base stations and core networks.

[0041] like Figure 1 As shown, the resource determination method may include the following steps:

[0042] In step S101, a first resource for transmitting a demodulation reference signal for a physical uplink shared channel is determined, which overlaps with a second resource in an uplink subband configured for the terminal, wherein the second resource is not used for transmitting the demodulation reference signal;

[0043] In step S102, an available third resource is determined, and the demodulation reference signal is transmitted through the third resource.

[0044] Figure 2 This is a schematic diagram illustrating several uplink subbands according to embodiments of the present disclosure.

[0045] Network devices can configure uplink subbands for terminals in downlink time slots, taking as an example the frequency domain resources corresponding to the downlink time slot including a bandwidth part (BWP).

[0046] In one embodiment, such as Figure 2 As shown in the left time slot, in the downlink time slot, the frequency domain resources corresponding to the uplink subband do not overlap with the frequency domain resources of the downlink resources used for downlink reception;

[0047] In one embodiment, such as Figure 2 As shown in the intermediate time slot, in the downlink time slot, the frequency domain resources corresponding to the uplink subband completely overlap with the frequency domain resources of the downlink resources used for downlink reception;

[0048] In one embodiment, such as Figure 2 As shown in the right-hand time slot, in the downlink time slot, the frequency domain resources corresponding to the uplink subband partially overlap with the frequency domain resources of the downlink resources used for downlink reception.

[0049] The following example illustrates the case where the frequency domain resources corresponding to the uplink subband do not overlap with the frequency domain resources used for downlink reception in the downlink time slot.

[0050] Figure 3 This is a schematic diagram illustrating the relationship between several uplink resources and second resources used for uplink transmission, according to embodiments of the present disclosure.

[0051] like Figure 3 As shown in scenario a, the network device configures an uplink subband for the terminal within the downlink time slot. This uplink subband corresponds to the entire downlink time slot in the time domain. The uplink resources used for uplink transmission within the uplink subband correspond to a portion of the uplink subband in the frequency domain and the entire time slot in the time domain. The second resource corresponds to the entire uplink subband in the frequency domain and a portion of the time slot in the time domain. The uplink resources used for uplink transmission within the uplink subband overlap with the second resource.

[0052] like Figure 3 As shown in scenario b, the network device configures an uplink subband for the terminal within the downlink time slot. This uplink subband corresponds to the entire downlink time slot in the time domain. The uplink resources used for uplink transmission within the uplink subband correspond to a portion of the uplink subband in the frequency domain and a portion of the time slot in the time domain. The second resource corresponds to the entire uplink subband in the frequency domain and a portion of the time slot in the time domain. The uplink resources used for uplink transmission within the uplink subband overlap with the second resource.

[0053] like Figure 3 As shown in scenario c, the network device configures an uplink subband for the terminal within the downlink time slot. This uplink subband corresponds to the entire downlink time slot in the time domain. The uplink resources used for uplink transmission within the uplink subband correspond to a portion of the uplink subband in the frequency domain and a portion of the time slot in the time domain. The second resource also corresponds to a portion of the uplink subband in the frequency domain and a portion of the time slot in the time domain. The uplink resources used for uplink transmission within the uplink subband overlap with the second resource.

[0054] like Figure 3 As shown in scenario d, the network device configures an uplink subband for the terminal within the downlink time slot. This uplink subband corresponds to the entire downlink time slot in the time domain. The uplink resources used for uplink transmission within the uplink subband correspond to a portion of the uplink subband in the frequency domain and the entire time slot in the time domain. The second resource corresponds to a portion of the uplink subband in the frequency domain and a portion of the time slot in the time domain. The uplink resources used for uplink transmission within the uplink subband overlap with the second resource.

[0055] It should be noted that, Figure 3 This only illustrates several cases where uplink resources used for uplink transmission overlap with second resources in the uplink subband, but the cases where uplink resources used for uplink transmission overlap with second resources in the uplink subband are not limited to these examples. Figure 3 The situation is shown below.

[0056] Figure 4 This is a schematic diagram illustrating the relationship between an uplink resource and a second resource for uplink transmission, according to an embodiment of the present disclosure.

[0057] In one embodiment, a time slot may contain 14 symbols, where the symbols are Orthogonal Frequency Division Multiplexing (OFDM) symbols.

[0058] by Figure 3 Taking case a as an example, the resources used to transmit PUSCH correspond to the entire time slot in the time domain, that is, to symbols 1 to 14, while the second resource corresponds to symbols 1 to 3 in the time domain. Where the PUSCH type is PUSCH mapping type A, and the network device does not indicate an additional demodulation reference signal (DMRS) to the terminal, then the DMRS of the PUSCH can be located in the 2nd or 3rd symbol of the time slot.

[0059] For example Figure 4 As shown, taking the DMRS located in the third symbol of the time slot as an example, the first resource (the third symbol) used for transmitting the DMRS overlaps with the second resource (the first to third symbols) on the third symbol. Since the second resource is not used for transmitting the DMRS, the DMRS on the third symbol cannot be transmitted normally. Since the DMRS is used for demodulation-related operations of PUSCH, this will cause a degrade in the transmission performance of PUSCH.

[0060] According to this embodiment, when the first resource of DMRS used for transmitting PUSCH in the uplink subband overlaps with the second resource not used for transmitting DMRS, the terminal can determine the available third resource. For example, the third resource is a resource in the uplink subband that does not overlap with the second resource, and then transmit DMRS on the third resource, thereby ensuring the normal transmission of DMRS and thus ensuring good transmission performance of PUSCH.

[0061] In addition, after the third resource is determined, the terminal may send nothing or send a PUSCH on the resource where the first and second resources overlap.

[0062] In one embodiment, the second resource includes a Rate Matching Resource (RMR), which is a resource used for rate matching.

[0063] In one embodiment, a terminal configured with an uplink subband in the downlink time slot can perform uplink transmission in the uplink subband of the downlink time slot, and this terminal can be called a Subband Full Duplex (SBFD) terminal. A terminal not configured with an uplink subband in the downlink time slot can only receive downlink transmission in the downlink time slot, and this terminal can be called a legacy terminal.

[0064] Network devices can schedule downlink transmissions of traditional terminals in downlink time slots. These downlink transmissions include, but are not limited to, semi-static Physical Downlink Shared Channel (PDSCH), dynamic PDSCH, Physical Downlink Control Channel (PDCCH), Channel State Information Reference Signal (CSI-RS), and Positioning Reference Signal (PRS).

[0065] When downlink and uplink subbands overlap, the uplink transmission of the SBFD terminal in the uplink subband will be interfered with. To solve this problem, network devices can configure rate matching resources for the SBFD terminal in the uplink subband. The SBFD terminal can then perform rate matching based on these resources, thereby avoiding conflicts between downlink and uplink subbands. However, the SBFD terminal cannot transmit DMRS within the rate matching resources; therefore, the second resource can include rate matching resources.

[0066] Figure 5A This is a schematic flowchart illustrating another resource determination method according to embodiments of the present disclosure. Figure 5A As shown, the third resource to be determined as available includes:

[0067] In step S501, among the time-domain resources used to transmit the physical uplink shared channel, a first time-domain resource that does not overlap with the time-domain resources of the second resource is determined;

[0068] In step S502, based on the relevant parameters of the demodulation reference signal pattern configured by the network device, the available time-domain resources in the first time-domain resources are determined.

[0069] In one embodiment, the time-domain resources used for transmitting PUSCH may include first time-domain resources that do not overlap with the time-domain resources of the second resources. Then, the terminal can determine the time-domain resources in the first time-domain resources based on the relevant parameters of the demodulation reference signal pattern configured by the network device, and use them as the available time-domain resources in the third resources.

[0070] Figure 5B This is a schematic diagram illustrating an available third resource according to an embodiment of the present disclosure.

[0071] For example Figure 5B As shown, in Figure 4Based on this, the time-domain resources used for PUSCH transmission are symbols 1 to 14. Symbols 4 to 14 do not overlap with the second resource. Therefore, the terminal can determine the available third resource from symbols 4 to 14 based on the relevant parameters of the DMRS pattern configured in the network device. For example, the relevant parameters of the DMRS pattern include the demodulation reference signal type A position, i.e., dmrs-TypeA-Position. Based on these parameters, symbol 6 can be determined as a time-domain resource among the available third resources, and thus the terminal can transmit DMRS on symbol 6.

[0072] Figure 6A This is a schematic flowchart illustrating yet another resource determination method according to embodiments of the present disclosure. Figure 6A As shown, the third resource to be determined as available includes:

[0073] In step S601, among the time-domain resources used to transmit the physical uplink shared channel, at least one available symbol that is closest to the time-domain resource of the second resource and is located after the time-domain resource of the second resource in the time domain is determined as a time-domain resource in the available third resource.

[0074] In one embodiment, in the time-domain resources used for transmitting PUSCH, the terminal may determine at least one available symbol that is closest to the time-domain resource of the second resource and is located after the time-domain resource of the second resource in the time domain as a time-domain resource in the available third resource. The number of symbols among the at least one available symbol may be equal to the number of symbols overlapping between the first and second resources.

[0075] In one embodiment, the available symbols include symbols in the time-domain resources used for transmitting data of the physical uplink shared channel.

[0076] The time-domain resources used for transmitting PUSCH include the resources for transmitting PUSCH DMRS and the resources for transmitting PUSCH data. If the resources for transmitting PUSCH DMRS are used as a third available resource, then the DMRS originally transmitted on that resource cannot be transmitted normally. Therefore, it is necessary to determine the available symbols in the time-domain resources used for transmitting PUSCH data.

[0077] Figure 6B This is a schematic diagram illustrating another available third resource according to an embodiment of the present disclosure.

[0078] like Figure 6B As shown, in Figure 4Based on this, the symbol that overlaps with the first resource and the second resource is the third symbol. Therefore, the number of overlapping symbols is 1, and thus 3 usable symbols can be determined.

[0079] The time-domain resources used for transmitting PUSCH are symbols 1 to 14. The 4th symbol is the one available symbol that is closest to the time-domain resource of the second resource and is located after the time-domain resource of the second resource in the time domain. Then the terminal can determine that the lower 4 symbols are the available time-domain resources in the third resource, and the terminal can transmit DMRS on the 4th symbol.

[0080] In one embodiment, the method further includes:

[0081] Determine a first number of symbols in the first resource that overlap with the second resource, and a second number of symbols contained in the first resource;

[0082] Determine the ratio of the first quantity to the second quantity;

[0083] Wherein, when the ratio is greater than a threshold, at least one available symbol among the time-domain resources of the first resource that is closest to the time-domain resource of the second resource and is located after the time-domain resource of the second resource is identified as a time-domain resource among the available third resources. The threshold may be indicated by the network device or agreed upon by the protocol.

[0084] In one embodiment, in the time-domain resource used to transmit PUSCH, there may be one or more DMRS transmitted. A first number of symbols in the first resource that overlap with the second resource and a second number of symbols contained in the first resource may be determined, thereby determining the ratio of the first number to the second number.

[0085] When the ratio exceeds a threshold, it indicates a relatively large overlap between the first and second resources of DMRS. If the terminal does not send DMRS on the first resource that overlaps with the second resource, it will severely impact the transmission performance of PUSCH. Therefore, it is possible to base... Figure 6A In the embodiment shown, the terminal determines at least one available symbol in the time domain resources of the first resource that is closest to the time domain resources of the second resource and is located after the time domain resources of the second resource as a time domain resource in the available third resource, and then transmits DMRS on the third resource. Accordingly, it can be ensured that the total amount of DMRS transmitted remains basically unchanged and the impact on the transmission performance of PUSCH is small.

[0086] Figure 7A This is a schematic flowchart illustrating yet another resource determination method according to embodiments of the present disclosure. Figure 7A As shown, the third resource to be determined as available includes:

[0087] In step S701, in response to the existence of a second time-domain resource for transmitting the demodulation reference signal and which does not overlap with the time-domain resource of the second resource in the time-domain resources used for transmitting the physical uplink shared channel, the second time-domain resource is determined to be a time-domain resource among the available third resources.

[0088] In one embodiment, the time-domain resources used for transmitting PUSCH can contain one or more DMRSs. Therefore, when a second resource overlaps with a first resource for transmitting DMRS, a second time-domain resource that is not overlapping with the second resource can still exist within the time-domain resources used for transmitting PUSCH. The terminal can then determine that the second time-domain resource is a third resource and transmit DMRS on that third resource. That is, within the first resource used for transmitting DMRS, the portion overlapping with the second resource is not used for transmitting DMRS; DMRS is only transmitted on the portion not overlapping with the second resource.

[0089] Figure 7B This is a schematic diagram illustrating the relationship between an uplink resource and a second resource for uplink transmission, according to an embodiment of the present disclosure.

[0090] In one embodiment, a time slot may contain 14 symbols, where the symbols are Orthogonal Frequency Division Multiplexing (OFDM) symbols.

[0091] like Figure 7B As shown, with Figure 3 Taking case a as an example, the resources used for transmitting PUSCH correspond to the entire time slot in the time domain, that is, to symbols 1 to 14, while the second resource corresponds to symbols 1 to 3 in the time domain. The PUSCH type is PUSCH mapping type A, and the network device indicates an additional demodulation reference signal to the terminal. Furthermore, the Pos parameter in the DMRS pattern related parameters configured in the higher-layer signaling is Pos3.

[0092] Accordingly, Figure 7B As shown, the terminal can determine that a DMRS is sent every 3 symbols, so the DMRS of PUSCH can be located in the 3rd, 6th, 9th and 12th symbols in the time slot.

[0093] The first resource (symbols 3, 6, 9, and 12) used for transmitting DMRS overlaps with the second resource (symbols 1 to 3) on the third symbol. Since the second resource is not used for transmitting DMRS, the DMRS on the third symbol cannot be transmitted normally.

[0094] Figure 7CThis is a schematic diagram illustrating yet another available third resource according to embodiments of the present disclosure.

[0095] like Figure 7C As shown, in Figure 7B Based on this, the symbol that overlaps with the first resource and the second resource is the third symbol. In the time-domain resources used for transmitting PUSCH, there exist second time-domain resources used for transmitting DMRS that do not overlap with the time-domain resources of the second resource, namely the 6th, 9th, and 12th symbols. Therefore... Figure 7C As shown, the terminal can determine that symbols 6, 9, and 12 are third resources, and therefore will not send DMRS with symbol 3, but will only send DMRS with symbols 6, 9, and 12.

[0096] In one embodiment, the method further includes:

[0097] Determine a first number of symbols in the first resource that overlap with the second resource, and a second number of symbols contained in the first resource;

[0098] Determine the ratio of the first quantity to the second quantity;

[0099] Specifically, when the ratio is less than or equal to a threshold, in response to the existence of a second time-domain resource among the time-domain resources used for transmitting the physical uplink shared channel, which is used for transmitting the demodulation reference signal and does not overlap with the time-domain resources of the second resource, the second time-domain resource is determined to be a time-domain resource among the available third resources. The threshold can be indicated by the network device or agreed upon by the protocol.

[0100] In one embodiment, in the time-domain resource used to transmit PUSCH, there may be one or more DMRS transmitted. A first number of symbols in the first resource that overlap with the second resource and a second number of symbols contained in the first resource may be determined, thereby determining the ratio of the first number to the second number.

[0101] When the ratio is less than or equal to the threshold, it indicates that there is relatively little overlap between the first and second resources for DMRS. If DMRS is not transmitted on the first resource that overlaps with the second resource, the impact on the transmission performance of PUSCH is small. Therefore, it can be based on Figure 7A In the illustrated embodiment, when the terminal has a second time-domain resource for transmitting DMRS that does not overlap with the second resource in the time-domain resources used for transmitting PUSCH, the second time-domain resource can be determined as a third resource. Therefore, DMRS will not be transmitted on the portion of the resource overlapping with the second resource; DMRS will only be transmitted on the portion of the resource that does not overlap with the second resource. Accordingly, although the total amount of DMRS transmitted is reduced, the impact on PUSCH transmission performance is minimal, and the terminal's DMRS transmission logic is simplified.

[0102] In one embodiment, the method further includes:

[0103] Determine a first number of symbols in the first resource that overlap with the second resource, and a second number of symbols contained in the first resource;

[0104] Determine the ratio of the first quantity to the second quantity;

[0105] Wherein, when the ratio is less than or equal to the threshold, in response to the existence of a second time-domain resource for transmitting demodulation reference signals that does not overlap with the time-domain resource of the second resource in the time-domain resources used for transmitting the physical uplink shared channel, the second time-domain resource is determined to be the third resource.

[0106] When the ratio is greater than a threshold, at least one available symbol in the time domain resources of the first resource that is closest to the time domain resource of the second resource and is located after the time domain resource of the second resource in the time domain is identified as a time domain resource in the available third resource.

[0107] The threshold can be indicated by the network device or agreed upon by the protocol. For example, the threshold can be 1 / 2.

[0108] In one embodiment, in the time-domain resource used to transmit PUSCH, there may be one or more DMRS transmitted. A first number of symbols in the first resource that overlap with the second resource and a second number of symbols contained in the first resource may be determined, thereby determining the ratio of the first number to the second number.

[0109] When the ratio exceeds a threshold, it indicates a significant overlap between the first and second resources for DMRS. If DMRS is not transmitted on the first resource overlapping with the second resource, it will severely impact PUSCH transmission performance. Therefore, at least one available symbol in the time domain of the first resource that is closest to and follows the time domain of the second resource can be identified as a available time domain resource in the third resource. DMRS can then be transmitted on this third resource. This ensures that the total amount of DMRS transmitted remains essentially constant, minimizing the impact on PUSCH transmission performance.

[0110] When the ratio is less than or equal to the threshold, it indicates that relatively few DMRS overlaps between the first and second resources. If DMRS is not transmitted on the first resources that overlap with the second resources, the impact on PUSCH transmission performance is minimal. Therefore, if there is a second time-domain resource used for PUSCH transmission that is also used for DMRS transmission and does not overlap with the second resource's time-domain resource, the second time-domain resource can be designated as the third resource. Then, DMRS will not be transmitted on the resources that overlap with the second resource; DMRS will only be transmitted on the resources that do not overlap with the second resource. Accordingly, although the total amount of DMRS transmitted is reduced, the impact on PUSCH transmission performance is minimal, and the logic for the terminal to transmit DMRS is simplified.

[0111] Figure 8A This is a schematic flowchart illustrating yet another resource determination method according to embodiments of the present disclosure. Figure 8A As shown, the method further includes:

[0112] In step S801, the first resource is determined based on the relevant parameters of the first demodulation reference signal pattern among the relevant parameters of the multiple demodulation reference signal patterns configured by the network device.

[0113] The third resource that is determined to be available includes:

[0114] In step S802, the third resource is determined based on the relevant parameters of the second demodulation reference signal pattern among the relevant parameters of the multiple demodulation reference signal patterns.

[0115] The parameters of the first set of DMRS patterns can be called the parameters of the preset DMRS patterns, and the parameters of the second set of DMRS patterns can be called the parameters of the optional DMRS patterns.

[0116] In one embodiment, the network device can configure multiple sets of DMRS pattern parameters for the terminal, and the terminal can select one set of DMRS pattern parameters to determine the resources used for DMRS transmission. For example, the resources used by the terminal for DMRS transmission based on the parameters of the first set of DMRS pattern are designated as the first resource, which overlaps with the second resource.

[0117] In this scenario, the terminal can select the parameters of a second DMRS pattern (other than the parameters of the first DMRS pattern) from among multiple DMRS pattern parameters to determine the resource used for DMRS transmission as the third resource. The determined third resource does not need to overlap with the second resource. Therefore, transmitting DMRS on the third resource will not conflict with the second resource, ensuring normal DMRS transmission.

[0118] In one embodiment, the relevant parameters of each DMRS pattern can be associated with priority, and the terminal can select the relevant parameters of the DMRS pattern one by one according to the priority from high to low to determine the resources used for transmitting DMRS.

[0119] For example, when a terminal selects parameters for another set of DMRS patterns besides those for the first set of DMRS patterns, it can first select parameters for one set of DMRS patterns according to priority from high to low to determine the resources used for transmitting DMRS. If the resources determined for transmitting DMRS still overlap with the first resource, it can select parameters for another set of DMRS patterns according to priority from high to low to determine the resources used for transmitting DMRS, until the resources determined for transmitting DMRS do not overlap with the first resource. Then the resources determined for transmitting DMRS can be used as the third resource.

[0120] Figure 8B This is a schematic diagram illustrating yet another available third resource according to embodiments of the present disclosure.

[0121] like Figure 8B As shown, in Figure 4 Based on this, if the first resource and the second resource determined by the terminal according to the first DMRS pattern overlap on the third symbol, then the terminal can select the second DMRS pattern to determine the third resource for transmitting the DMRS. For example, if the resource determined by the second DMRS pattern is for transmitting the DMRS on the sixth symbol, which does not overlap with the second resource, then the sixth symbol can be determined as the available time-domain resource in the third resource, and thus the DMRS can be transmitted on the sixth symbol.

[0122] It should be noted that the embodiments of this disclosure are applicable to the transmission of any type of PUSCH. In one embodiment, the type of the physical uplink shared channel includes at least one of the following:

[0123] Physical uplink shared channel of mapping type A, also known as PUSCH mapping type A;

[0124] Physical uplink shared channel of mapping type B, also known as PUSCH mapping type B.

[0125] It should be noted that the embodiments of this disclosure are applicable to the relevant parameters of any DMRS pattern. In one embodiment, the relevant parameters of the demodulated reference signal image include at least one of the following:

[0126] Single demodulation reference signal (single DMRS), double demodulation reference signal (double DMRS), additional demodulation reference signal (additional DMRS), intra-slot frequency hopping enabled (intra-FH, FH stands for Frequency Hopping), and intra-slot frequency hopping disabled.

[0127] Figure 9 This is a schematic flowchart illustrating a resource determination method according to an embodiment of the present disclosure. The resource determination method shown in this embodiment can be executed by a network device that can communicate with a terminal. The network device includes, but is not limited to, base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations. The terminal includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices.

[0128] like Figure 9 As shown, the resource determination method may include the following steps:

[0129] In step S901, a first resource for the terminal to transmit a demodulation reference signal for the physical uplink shared channel is determined to overlap with a second resource in the uplink subband configured for the terminal, wherein the second resource is not used to transmit the demodulation reference signal.

[0130] In step S902, an available third resource is determined, and the demodulation reference signal transmitted by the terminal is received in the third resource.

[0131] In one embodiment, to Figure 3 Taking case a as an example, the resources used to transmit PUSCH correspond to the entire time slot in the time domain, that is, to symbols 1 to 14, while the second resource corresponds to symbols 1 to 3 in the time domain. Where the PUSCH type is PUSCH mapping type A, and the network device does not indicate an additional demodulation reference signal (DMRS) to the terminal, then the DMRS of the PUSCH can be located in the 2nd or 3rd symbol of the time slot.

[0132] For example Figure 4As shown, taking the DMRS located in the third symbol of the time slot as an example, the first resource (the third symbol) used for transmitting the DMRS overlaps with the second resource (the first to third symbols) on the third symbol. Since the second resource is not used for transmitting the DMRS, the DMRS on the third symbol cannot be transmitted normally. Since the DMRS is used for demodulation-related operations of PUSCH, this will cause a degrade in the transmission performance of PUSCH.

[0133] According to this embodiment, when the first resource for transmitting PUSCH DMRS in the uplink subband overlaps with the second resource not used for transmitting DMRS, the network device can determine the available third resource, for example, the third resource is a resource in the uplink subband that does not overlap with the second resource, and then receive the DMRS transmitted by the terminal on the third resource, thereby ensuring the normal reception of DMRS and thus ensuring good transmission performance of PUSCH.

[0134] In one embodiment, the second resource includes a rate matching resource (RMR), which is a resource used for rate matching.

[0135] In one embodiment, a terminal configured with an uplink subband in the downlink time slot can perform uplink transmission in the uplink subband of the downlink time slot; this terminal can be called a subband full-duplex (SBFD) terminal. A terminal not configured with an uplink subband in the downlink time slot can only receive downlink transmissions in the downlink time slot; this terminal can be called a legacy terminal.

[0136] Network devices can schedule downlink transmissions of traditional terminals during downlink time slots. These downlink transmissions include, but are not limited to, semi-static PDSCH, dynamic PDSCH, PDCCH, CSI-RS, and PRS.

[0137] When downlink and uplink subbands overlap, the uplink transmission of the SBFD terminal in the uplink subband will be interfered with. To solve this problem, network devices can configure rate matching resources for the SBFD terminal in the uplink subband. The SBFD terminal can then perform rate matching based on these resources, thereby avoiding conflicts between downlink and uplink subbands. However, the SBFD terminal cannot transmit DMRS within the rate matching resources; therefore, the second resource can include rate matching resources.

[0138] In one embodiment, determining the available third resource includes:

[0139] In the time-domain resources of the physical uplink shared channel transmitted by the terminal, a first time-domain resource that does not overlap with the time-domain resources of the second resource is determined;

[0140] Based on the relevant parameters of the demodulation reference signal pattern configured for the terminal, the available time-domain resources in the third available resources are determined in the first time-domain resources.

[0141] In one embodiment, the time-domain resources used for transmitting PUSCH may include first time-domain resources that do not overlap with the time-domain resources of the second resources. Then, the network device can determine the available third resources in the first time-domain resources based on the relevant parameters of the demodulation reference signal pattern configured by the network device.

[0142] For example Figure 5B As shown, in Figure 4 Based on this, the time-domain resources used for PUSCH transmission are symbols 1 to 14, where symbols 4 to 14 do not overlap with the second resource. Therefore, the network device can determine the available third resource from symbols 4 to 14 based on the relevant parameters of the DMRS pattern configured in the network device. For example, the relevant parameters of the DMRS pattern include the demodulation reference signal type A position, i.e., dmrs-TypeA-Position. Based on these parameters, symbol 6 can be determined as a time-domain resource among the available third resources, and thus the terminal can receive DMRS transmission on symbol 6.

[0143] In one embodiment, determining the available third resource includes:

[0144] In the time-domain resources of the physical uplink shared channel transmitted by the terminal, at least one available symbol that is closest to the time-domain resource of the second resource and is located after the time-domain resource of the second resource in the time domain is determined as the time-domain resource of the available third resource.

[0145] In one embodiment, in the time-domain resources for terminal PUSCH transmission, the network device may determine at least one available symbol that is closest to the time-domain resource of the second resource and is located after the time-domain resource of the second resource in the time domain as a time-domain resource in the available third resource. The number of symbols among the at least one available symbol may be equal to the number of symbols overlapping between the first and second resources.

[0146] In one embodiment, the available symbols include symbols in the time-domain resources used for transmitting data of the physical uplink shared channel.

[0147] The time-domain resources used for transmitting PUSCH include the resources for transmitting PUSCH DMRS and the resources for transmitting PUSCH data. If the resources for transmitting PUSCH DMRS are used as a third available resource, then the DMRS originally transmitted on that resource cannot be transmitted normally. Therefore, it is necessary to determine the available symbols in the time-domain resources used for transmitting PUSCH data.

[0148] like Figure 6B As shown, in Figure 4 Based on this, the symbol that overlaps with the first resource and the second resource is the third symbol. Therefore, the number of overlapping symbols is 1, and thus 3 usable symbols can be determined.

[0149] The time-domain resources used for transmitting PUSCH are symbols 1 to 14. The first available symbol that is closest to the time-domain resource of the second resource and is located after the time-domain resource of the second resource is the fourth symbol. Then the network device can determine that the lower four symbols are the available time-domain resources in the third resource, and the network device can receive the DMRS transmitted by the group flood end on the fourth symbol.

[0150] In one embodiment, the method further includes:

[0151] Determine a first number of symbols in the first resource that overlap with the second resource, and a second number of symbols contained in the first resource;

[0152] Determine the ratio of the first quantity to the second quantity;

[0153] Wherein, when the ratio is greater than the threshold, at least one available symbol in the time domain resources of the first resource that is closest to the time domain resource of the second resource and is located after the time domain resource of the second resource in the time domain is determined as the time domain resource of the available third resource.

[0154] In one embodiment, in the time-domain resource used to transmit PUSCH, there may be one or more DMRS transmitted. A first number of symbols in the first resource that overlap with the second resource and a second number of symbols contained in the first resource may be determined, thereby determining the ratio of the first number to the second number.

[0155] When the ratio exceeds a threshold, it indicates that a relatively large number of DMRS overlap between the first and second resources. If the network device does not receive DMRS sent by the terminal on the first resource that overlaps with the second resource, it will severely impact the transmission performance of PUSCH. Therefore, the network device can identify at least one available symbol in the time domain of the first resource that is closest to and follows the time domain of the second resource as a available time domain resource in the third resource. Then, it can receive DMRS sent by the terminal on the third resource. This ensures that the total amount of DMRS received from the terminal remains essentially constant, minimizing the impact on PUSCH transmission performance.

[0156] In one embodiment, determining the available third resource includes:

[0157] In response to the existence of a second time-domain resource for transmitting the demodulation reference signal and which does not overlap with the time-domain resource of the second resource in the time-domain resources of the physical uplink shared channel transmitted by the terminal, the second time-domain resource is determined to be a time-domain resource among the available third resources.

[0158] In one embodiment, in the time-domain resource used to transmit PUSCH, there may be one or more DMRS transmitted. A first number of symbols in the first resource that overlap with the second resource and a second number of symbols contained in the first resource may be determined, thereby determining the ratio of the first number to the second number.

[0159] When the ratio exceeds a threshold, it indicates a relatively large overlap between the first and second resources of DMRS. If the terminal does not send DMRS on the first resource that overlaps with the second resource, it will severely impact the transmission performance of PUSCH. Therefore, it is possible to base... Figure 6A In the embodiment shown, the terminal determines at least one available symbol in the time domain resources of the first resource that is closest to the time domain resources of the second resource and is located after the time domain resources of the second resource as a time domain resource in the available third resource, and then transmits DMRS on the third resource. Accordingly, it can be ensured that the total amount of DMRS transmitted remains basically unchanged and the impact on the transmission performance of PUSCH is small.

[0160] In one embodiment, determining the available third resource includes: in response to the existence of a second time-domain resource for transmitting the demodulation reference signal and which does not overlap with the time-domain resource of the second resource among the time-domain resources used for transmitting the physical uplink shared channel, determining the second time-domain resource as a time-domain resource among the available third resources.

[0161] In one embodiment, the time-domain resources used for transmitting PUSCH can contain one or more DMRS. Therefore, when a second resource overlaps with a first resource for transmitting DMRS, a second time-domain resource that does not overlap with the second resource can still exist within the time-domain resources used for transmitting PUSCH. The network device can then determine that the second time-domain resource is a third resource and receive the PUSCH sent by the terminal on the third resource. That is, in the first resource used for transmitting DMRS, the portion overlapping with the second resource will not receive the DMRS sent by the terminal; the DMRS sent by the terminal will only be received on the portion of the first resource that does not overlap with the second resource.

[0162] In one embodiment, a time slot may contain 14 symbols, where the symbols are Orthogonal Frequency Division Multiplexing (OFDM) symbols.

[0163] like Figure 7B As shown, with Figure 3 Taking case a as an example, the resources used for transmitting PUSCH correspond to the entire time slot in the time domain, that is, to symbols 1 to 14, while the second resource corresponds to symbols 1 to 3 in the time domain. The PUSCH type is PUSCH mapping type A, and the network device indicates an additional demodulation reference signal to the terminal. Furthermore, the Pos parameter in the DMRS pattern related parameters configured in the higher-layer signaling is Pos3.

[0164] Accordingly, Figure 7B As shown, the network device can determine that the terminal sends a DMRS every 3 symbols, so the DMRS of PUSCH can be located in the 3rd, 6th, 9th and 12th symbols in the time slot.

[0165] The first resource (symbols 3, 6, 9, and 12) used for transmitting DMRS overlaps with the second resource (symbols 1 to 3) on the third symbol. Since the second resource is not used for transmitting DMRS, the DMRS on the third symbol cannot be transmitted normally.

[0166] like Figure 7C As shown, in Figure 7B Based on this, the symbol that overlaps with the first resource and the second resource is the third symbol. In the time-domain resources used for transmitting PUSCH, there exist second time-domain resources used for transmitting DMRS that do not overlap with the time-domain resources of the second resource, namely the 6th, 9th, and 12th symbols. Therefore... Figure 7C As shown, the network device can identify symbols 6, 9, and 12 as third resources, and therefore will not receive DMRS sent by the terminal with symbol 3, but will only receive DMRS sent by the terminal with symbols 6, 9, and 12.

[0167] In one embodiment, the method further includes:

[0168] Determine a first number of symbols in the first resource that overlap with the second resource, and a second number of symbols contained in the first resource;

[0169] Determine the ratio of the first quantity to the second quantity;

[0170] Wherein, when the ratio is less than or equal to the threshold, in response to the existence of a second time-domain resource for transmitting the demodulation reference signal and not overlapping with the time-domain resource of the second resource in the time-domain resources of the physical uplink shared channel transmitted by the terminal, the second time-domain resource is determined to be a time-domain resource among the available third resources.

[0171] In one embodiment, in the time-domain resource used to transmit PUSCH, there may be one or more DMRS transmitted. A first number of symbols in the first resource that overlap with the second resource and a second number of symbols contained in the first resource may be determined, thereby determining the ratio of the first number to the second number.

[0172] When the ratio is less than or equal to the threshold, it indicates that relatively few DMRS overlap between the first and second resources. If DMRS is not transmitted on the first resource that overlaps with the second resource, the impact on PUSCH transmission performance is minimal. Therefore, network devices can determine the second time-domain resource as the third resource when there is a second time-domain resource for transmitting DMRS that does not overlap with the second resource's time-domain resource. Then, DMRS transmitted by the terminal will not be received on the resource that overlaps with the second resource; it will only be received on the resource that does not overlap with the second resource. Accordingly, although the total amount of DMRS transmitted is reduced, the impact on PUSCH transmission performance is minimal, and it simplifies the logic of terminal DMRS transmission.

[0173] In one embodiment, the method further includes:

[0174] The first resource is determined based on the relevant parameters of the first demodulation reference signal pattern among the multiple demodulation reference signal patterns configured for the terminal.

[0175] The third resource that is determined to be available includes:

[0176] The third resource is determined based on the relevant parameters of the second demodulation reference signal pattern among the multiple sets of demodulation reference signal patterns.

[0177] The parameters of the first set of DMRS patterns can be called the parameters of the preset DMRS patterns, and the parameters of the second set of DMRS patterns can be called the parameters of the optional DMRS patterns.

[0178] In one embodiment, the network device can configure multiple sets of DMRS pattern parameters for the terminal, and the network device can select one set of DMRS pattern parameters to determine the resources used for DMRS transmission. For example, the network device uses the first set of DMRS pattern parameters to select the first resource for DMRS transmission, which overlaps with the second resource.

[0179] In this scenario, the network device can select the parameters of a second DMRS pattern (other than the parameters of the first DMRS pattern) from among multiple DMRS pattern parameters to determine the resource used for DMRS transmission as the third resource. The determined third resource does not need to overlap with the second resource. Therefore, transmitting DMRS on the third resource will not conflict with the second resource, ensuring normal DMRS transmission.

[0180] In one embodiment, the relevant parameters of each DMRS pattern can be associated with priority, and the network device can select the relevant parameters of the DMRS pattern one by one according to the priority to determine the resources used for transmitting DMRS.

[0181] For example, when a network device selects parameters for another set of DMRS patterns besides the parameters for the first set of DMRS patterns, it can first select the parameters for one set of DMRS patterns according to the priority from high to low to determine the resources used for transmitting DMRS. If the resources used for transmitting DMRS still overlap with the first resource, it can select the parameters for another set of DMRS patterns according to the priority from high to low to determine the resources used for transmitting DMRS, until the resources used for transmitting DMRS do not overlap with the first resource. Then the resources used for transmitting DMRS can be used as the third resource.

[0182] like Figure 8B As shown, in Figure 4Based on this, if the first resource and the second resource determined by the first DMRS pattern overlap on the third symbol, the network device can select the second DMRS pattern to determine the third resource for transmitting the DMRS. For example, if the resource determined by the second DMRS pattern is for transmitting the DMRS on the sixth symbol, which does not overlap with the second resource, then the sixth symbol can be determined as the available time-domain resource in the third resource, and the DMRS transmitted by the terminal can be received on the sixth symbol.

[0183] It should be noted that the embodiments of this disclosure are applicable to the transmission of any type of PUSCH. In one embodiment, the type of the physical uplink shared channel includes at least one of the following:

[0184] Physical uplink shared channel of mapping type A, also known as PUSCH mapping type A;

[0201] Processing module 1101 is configured to determine a first resource used by the terminal for transmitting a demodulation reference signal of the physical uplink shared channel, which overlaps with a second resource in the uplink subband configured for the terminal, wherein the second resource is not used for transmitting the demodulation reference signal; and determine a third available resource.
