It should be noted that in this application embodiment, only the base station in the NR system is used as an example, but the specific type of base station is not limited.

[0021] The PSBCH signal generation method, apparatus, terminal, and storage medium provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0022] Please see Figure 2 , Figure 2 This is a flowchart of a PSBCH signal generation method provided in an embodiment of this application. This method is applied to a terminal, such as... Figure 2 As shown, it includes the following steps:

[0023] Step 201: Generate a PSBCH signal, wherein the PSBCH signal includes first indication information, the first indication information being used to indicate transmission resources, wherein the transmission resources include at least one of uplink resources and downlink resources.

[0024] The aforementioned PSBCH signal can be understood as the signal transmitted in the PSBCH, or it can be directly referred to as PSBCH.

[0025] The PSBCH signal can be generated based on the resource configuration sent by the network-side device received by the terminal, or the PSBCH signal can be generated by the terminal based on pre-configured information. No specific limitation is made in this regard.

[0026] The aforementioned first indication information may be a portion of the bits in the aforementioned PSBCH signal, for example, the aforementioned first indication information may be a portion of the aforementioned PSBCH signal. That is to say, the aforementioned PSBCH signal may include other information in addition to the aforementioned first indication information, and there is no limitation on this.

[0027] The aforementioned uplink resources can refer to the uplink resources of the terminal in the wireless communication system (e.g., LTE or NR system), that is, the resources for transmitting uplink signals between the terminal and the network-side equipment. The aforementioned downlink resources can refer to the downlink resources of the terminal in the wireless communication system (e.g., LTE or NR system), that is, the resources for transmitting downlink signals between the terminal and the network-side equipment. In this application embodiment, LTE resources are mainly used as examples for illustration.

[0028] The aforementioned first indication information, used to indicate transmission resources, can be understood as indicating resource configuration information for transmission. For example, the aforementioned first indication information can indicate at least one of the following transmission resources:

[0029] Resource configuration index, resource quantity, offset, and period.

[0030] In this embodiment of the invention, the above steps enable the indication of at least one of uplink and downlink resources via the PSBCH signal, thereby improving the resource configuration capability of the Sidelink. For example, a terminal within the coverage of an LTE network-side device can indicate the LTE uplink or LTE downlink resources to a terminal outside the coverage of that network-side device via the PSBCH signal, and the PSBCH signal can be the PSBCH signal of an NR Sidelink; as another example, a terminal within the coverage of an NR network-side device can indicate the NR uplink or NR downlink resources to a terminal outside the coverage of that network-side device via the PSBCH signal, and the PSBCH signal can be the PSBCH signal of an LTE Sidelink.

[0031] In this embodiment of the application, it can be applied to scenarios where the indication content of the PSBCH signal is set according to the obtained configuration information, such as setting the first indication information mentioned above. It can also be applied to scenarios where the PSBCH signal is obtained and the meaning of the PSBCH signal indication is understood, such as understanding the meaning of the first indication information mentioned above.

[0032] Furthermore, embodiments of this application may also include performing signal processing operations on the aforementioned PSBCH signal, such as sending the aforementioned PSBCH signal or demodulating the aforementioned PSBCH signal, etc., without limitation.

[0033] As an optional implementation, the PSBCH signal further includes:

[0034] The second indication information is used to indicate the type of transmission resource.

[0035] The second indication information mentioned above can be 1 bit. For example, the value of this 1 bit can indicate whether the type of transmission resource is LTE or NR. Of course, the type of transmission resource can also be pre-configured. For example, 1 bit of the PSBCH signal can be used to indicate the network of the transmission resource (e.g., LTE if NR) or the type of transmission resource provided in the pre-configuration (e.g., LTE resource configuration or NR resource configuration).

[0036] As an optional implementation, the first indication information mentioned above is Time Division Duplexing (TDD) configuration indication information (which can be abbreviated as TDD-config).

[0037] In the embodiments of this application, the first indication information may include a first position bit, a second position bit, and a third position bit, wherein the first position bit, the second position bit, and the third position bit may be represented by X, Y, and Z, respectively. For example, the above TDD configuration indication information may have X+Y+Z=12 bits, which is composed of the bit sequence a_0, a_1, a_2, a_3, ..., a_11.

[0038] Furthermore, the first bit position can be 1 bit, the second bit position can be 4 bits, and the third bit position can be 7 bits. Of course, this is not a limitation. For example, the number of bits in the first indication information can be greater than or less than 12 bits. This embodiment of the application uses 12 bits as an example for illustration.

[0039] In the above implementation, uplink and downlink transmission resources can be indicated by TDD configuration indication information.

[0040] As an optional implementation, the above-mentioned transmission resources are determined by at least one of the following:

[0041] Network-side configuration, pre-configuration, protocol agreement, terminal configuration, and other terminal instructions.

[0042] Among them, the above-mentioned network-side configuration can be the network-side configuration of the above-mentioned transmission resources, the above-mentioned pre-configuration can be the pre-configuration of the above-mentioned transmission resources, the above-mentioned protocol agreement can be the protocol agreement of the transmission resources, the above-mentioned terminal configuration can be the terminal determining the transmission resources, and the above-mentioned other terminal indication can be the other terminal indicating the transmission resources.

[0043] For example, when a terminal obtains LTE resource configuration information (such as tdd-Config or subframeAssignment in LTE SIB1) from an LTE network-side device, the terminal can obtain PSBCH content through at least one method, such as network configuration, pre-configuration, instructions from other terminals, protocol agreement, or self-determination. Furthermore, it can obtain first indication information, such as SL-TDD-Config. The LTE resource configuration information may include TDD-Config or subframeAssignment from System Information Block (SIB) 1. For example, after obtaining the LTE resource configuration information, the corresponding content in the PSBCH can be set to the same or compatible content as the LTE resource configuration information, such as at least one of the following: same or compatible resource configuration index, resource quantity, offset, and period.

[0044] For example, when a terminal obtains NR resource configuration information from an LTE network-side device, the terminal can obtain the PSBCH content through at least one method, such as network configuration, pre-configuration, instructions from other terminals, protocol agreement, or its own determination. Furthermore, it can obtain first indication information, such as SL-TDD-Config. This NR resource configuration information may include NR-TDD-UL-DL-ConfigCommon, contained in the SIB provided by the LTE network-side device for NR SL configuration.

[0045] It should be noted that, in this embodiment, the unit of time domain offset can be a time slot, second, millisecond, microsecond, number of subframes, or number of frames. This embodiment uses a time slot as an example. When performing time domain offset, the offset can be performed cyclically from left to right or from right to left. This embodiment uses a cyclic offset from right to left as an example.

[0046] In addition, in the embodiments of this application, the number of uplink resources refers to the number of consecutive uplink sources counted backward from the last uplink source of the pattern, or the number of uplink sources contained in a pattern. For example, the number of uplink time slots refers to the number of consecutive uplink time slots counted backward from the last uplink time slot, or the number of uplink time slots contained in a pattern.

[0047] As an optional implementation, the first bit of the first indication information is used to indicate at least one of the following:

[0048] Resource configuration index, resource quantity, offset, and period.

[0049] Wherein, the first bit can be one or more most significant bits (MSB) of the first indication information or the PSBCH signal, or the first bit can be one or more least significant bits (LSB) of the first indication information or the PSBCH signal. For example, K or J MSBs of the first indication information or the PSBCH signal, K or J LSBs of the first indication information or the PSBCH signal, where K and J are integers greater than or equal to 1.

[0050] In this embodiment of the application, MSB and LSB can be defined as follows:

[0051] The left side is the MSB, and the right side is the LSB, or

[0052] The left side is the LSB, and the right side is the MSB.

[0053] In this embodiment, the left-hand side of the bit sequence is designated as the MSB and the right-hand side as the LSB. Other orders are not excluded, such as the reverse: the left-hand side is designated as the LSB and the right-hand side as the MSB.

[0054] In one implementation, when the first bit is K bits, the value of the first bit within a first range is used to indicate the resource configuration index of the transmission resource, where K is an integer greater than or equal to 1.

[0055] The aforementioned K can be 1, 3, 5, 8, 9 bits, etc., and there is no limitation on this. In addition, when the value of the first bit is within the second range, it can be used to indicate that the mode of the transmission resource is Frequency Division Duplexing (FDD).

[0056] The first and second ranges mentioned above can be pre-configured, agreed upon by the protocol, or configured on the network side. Furthermore, the first range can be all or part of the values ​​of the first bit, meaning the second bit may be omitted.

[0057] The following example illustrates how, when the transmission resource type is LTE or LTE resource configuration is provided in a pre-configured manner, the first bit in the PSBCH signal or the first bit in the SL-TDD-config indicates the aforementioned transmission resource, i.e., LTE resource information:

[0058] LTE resource information can be an index of LTE resource configuration, such as the index of LTE TDD configuration, or at least one of the uplink resource number, offset, and period of LTE resource configuration.

[0059] When the first bit is 3 bits, the value range indicated by the 3 bits is 0-7. At least some of the values ​​correspond to different LTE resource configurations. For example, values ​​0-6 are used to indicate the index of LTE configuration 0-6, and value 7 is used to indicate that the current mode is LTE FDD. An example of the correspondence is shown in Table 1:

[0060] Table 1:

[0061] Indication index LTE config 0 LTE TDD config 0 1 LTE TDD config 1 2 LTE TDD config 2 3 LTE TDD config 3 4 LTE TDD config 4 5 LTE TDD config 5 6 LTE TDD config 6 7 FDD

[0062] Furthermore, if the acquired LTE resource configuration information indicates FDD mode, the following period can be configured:

[0063] 1ms, 2ms, 5ms or 10ms.

[0064] Furthermore, SL-TDD-Config can also indicate that all resources within a period are uplink resources.

[0065] Alternatively, the position of the first bit mentioned above can be as follows:

[0066] The 3 MSBs (i.e., the 3 most significant bits) of SL-TDD-config, or

[0067] The 3 LSBs (i.e., the 3 least significant bits) of SL-TDD-config, or

[0068] Y's 3 MSBs, or

[0069] Y's 3 LSBs, or

[0070] Z's 3 MSBs, or

[0071] Z's 3 LSBs, or

[0072] The three MSBs of the PSBCH signal, or

[0073] The three LSBs of the PSBCH signal.

[0074] Additionally, when the terminal obtains LTE resource configuration information from the network-side device indicating the LTE TDD config index, the first bit of the PBSCH signal or SL-TDD-Config can be set to the value corresponding to the LTE TDD config index.

[0075] Of course, Table 1 above is just one example. For example, 0 to 4 can also indicate LTE TDD configuration, and the remaining value range can be used to indicate other content.

[0076] One example is as follows:

[0077] If the 32 bits of the PSBCH signal are numbered b0 to b31, then the bit indicating the type of transmission resource is numbered b0, b1, b30, or b31; if the 56 bits of the PSBCH signal (including CRC) are numbered b0 to b55, then the bit indicating the type of transmission resource is numbered b0, b1, b54, or b55. Assuming the transmitter needs to indicate LTE config 5, one implementation is to set the type indicator bit in the PSBCH signal to 0, indicating the type as LTE, the first bit to be the three MSBs in SL-TDD-config, and set the values ​​of a_0, a_1, and a_2 to 1, 0, and 1 respectively, thus indicating the current configuration index as LTE config 5.

[0078] In another implementation, when the first bit is J bits, the first bit is used to indicate at least one of the following:

[0079] Resource quantity, offset, and cycle;

[0080] Where J is an integer greater than or equal to 1.

[0081] The J mentioned above can be 1, 3, 5, 8, 9, 11 bits, etc., and there is no limitation on this.

[0082] The first bit can indicate each of the above-mentioned items individually or in combination.

[0083] For example: the first bit may include N first part bits, wherein the N first part bits are respectively used to indicate the number of resources of the transmission resource in the N resource patterns; or

[0084] The first bit may include a second part of bits, which are used to jointly indicate the transmission resources in the N resource patterns;

[0085] Where N is an integer greater than or equal to 1.

[0086] The first part of the bits mentioned above can be one or more bits, and the second part of the bits mentioned above can be one or more bits.

[0087] The aforementioned N first part bits are used to indicate the number of resources in the N resource patterns, and each first part bit can be used to indicate the number of resources in a resource pattern.

[0088] The second part of the bits is used to jointly indicate the transmission resources in the N resource patterns. This can be achieved by treating one resource configuration as multiple N resource patterns, with the second part of the bits jointly indicating the number of resources in these N resource patterns. For example, the second part of the bits consists of 4 or 5 bits jointly indicating the number of uplink time slots in resource pattern 1 and resource pattern 2.

[0089] Furthermore, the first bit mentioned above also includes M third part bits, which are used to indicate the offset and / or period in the N resource patterns;

[0090] Where M is an integer greater than or equal to 1.

[0091] The aforementioned third part of the bits can be one or more bits, and the number of bits in different third parts can be the same or different. For example, when M equals 2, one third part of the bits is 2 bits used to indicate the time domain offset_1 of resource pattern 1, and another third part of the bits is 2 bits used to indicate the time domain offset_2 of resource pattern 2; when M equals 3, one third part of the bits is 2 bits used to indicate the time domain offset_1 of resource pattern 1, another third part of the bits is 2 bits used to indicate the time domain offset_2 of resource pattern 2, and another third part of the bits is 2 bits used to indicate the period of resource pattern 1 and resource pattern 2.

[0092] It should also be noted that in the embodiments of this application, the first indication information may not indicate the offset and / or period in the N resource patterns. For example, the offset and / or period in the N resource patterns may be pre-configured, agreed upon by the protocol, etc.

[0093] The following examples illustrate J with values ​​of 8, 9, and 11:

[0094] The first bit is 8 bits:

[0095] The first bit indicates the number of uplink resources. Optionally, it may also indicate the offset value and / or period. The offset value and period can be obtained by at least one method, such as network configuration, pre-configuration, other user indication, or protocol agreement. If it is pre-configured or protocol agreed, it does not need to be indicated. That is, the indication of the offset value and period is optional.

[0096] One indication method is based on the LTE subcarrier spacing (SCS), specifically as follows:

[0097] Configuration splitting treats LTE resource configuration as one or two patterns. For example, if LTE resource configuration is considered as a 5ms long pattern, assuming the first bit indicates the number of uplink resources and the offset value, and the period is obtained by the protocol, the first bit is 4 bits, split into two indication fields. 2 bits are used to indicate the number of uplink time slots of the pattern, and 2 bits are used to indicate the time domain offset of the pattern.

[0098] For example, consider LTE resource configuration as two 5ms long patterns. Assume the first bit indicates the number of uplink resources and the offset value. The period is determined by the protocol. The first bit is 8 bits, divided into 4 indication fields. 2 bits are used to indicate the number of uplink time slots in pattern 1, 2 bits are used to indicate the time domain offset_1 of pattern 1, 2 bits are used to indicate the number of uplink time slots in pattern 2, and 2 bits are used to indicate the time domain offset_2 of pattern 2.

[0099] One embodiment may be as follows:

[0100] According to the LTE SCS instructions, and with resources configured for one pattern, it can be as follows:

[0101] Assuming the sender needs to indicate the configuration as LTE config 0, one implementation is:

[0102] The PSBCH signal is configured with the type indicator bit set to 0, assuming the type is LTE and the pattern period is 5ms. The first bit represents the four MSBs in the SL-TDD-config. a0 and a1 indicate the uplink slot number of the pattern, and a2 and a3 indicate the time offset of the pattern. Since the pattern has 3 uplink slots and a time offset of 0 slots, the values ​​of a0, a1, a2, and a3 are set to 1, 1, 0, and 0 respectively. The indicated uplink resource configuration is shown in Table 2 below.

[0103] Table 2:

[0104]

[0105] Here, " / " indicates that the corresponding subframe type is uncertain or unnecessary to acquire, meaning it does not affect the indication of the current resource. Furthermore, when indicating consecutive uplink or downlink resources, the above " / " can indicate that the corresponding subframe is neither an uplink nor a downlink resource.

[0106] If following the LTE SCS instructions and with resources configured for two patterns, the following can be done:

[0107] Assuming the transmitter needs to indicate the LTE config 6 configuration, one implementation is as follows:

[0108] The PSBCH signal is set to 0 for the type indicator bit, indicating LTE. The period of pattern1 equals the period of pattern2, with a pre-configured value of 5ms. The first bit represents the 8 MSBs in the SL-TDD-config. a0 and a1 indicate the number of uplink time slots for pattern1, a2 and a3 indicate the number of uplink time slots for pattern2, a4 and a5 indicate the time domain offset_1 for pattern1, and a6 and a7 indicate the time domain offset_2 for pattern2. Since pattern1 has 3 uplink time slots, pattern2 has 2 uplink time slots, pattern1 has a time domain offset of 0 slots, and pattern2 has a time domain offset of 1 slot, the values ​​of a0, a1, a2, a3, a4, a5, a6, and a7 are set to 1, 1, 1, 0, 0, 0, 0, 1 respectively. The indicated uplink resource configuration is shown in Table 3 below.

[0109] Table 3:

[0110]

[0111] Another way to indicate this is according to the SL SCS instruction, as follows:

[0112] Configuration splitting treats LTE resource configuration as one or two patterns.

[0113] For example, if we consider LTE resource configuration as a pattern with a length of 5ms, assuming the first bit indicates the number of uplink resources and the offset value, and the period is obtained by the protocol, the first bit is 4 bits, which is split into two indication fields. 2 bits are used to indicate the number of uplink time slots of the pattern, and 2 bits are used to indicate the time domain offset of the pattern.

[0114] For example, consider LTE resource configuration as two 5ms long patterns. Assume the first bit indicates the number of uplink resources and the offset value. The period is determined by the protocol. The first bit is 8 bits, divided into 4 indication fields. 2 bits are used to indicate the number of uplink time slots in pattern 1, 2 bits are used to indicate the time domain offset_1 of pattern 1, 2 bits are used to indicate the number of uplink time slots in pattern 2, and 2 bits are used to indicate the time domain offset_2 of pattern 2.

[0115] One embodiment may be as follows:

[0116] Following the SL SCS directive, and with resources configured for one pattern, the following can be done:

[0117] Assuming the transmitter needs to indicate the configuration as LTE config 0, u_SL = 1 (SL SCS = 30kHz), one implementation is:

[0118] The PSBCH signal is set to 0 for the type indicator bit, indicating LTE. The pattern period is pre-configured at 5ms. The first bit represents the four MSBs in the SL-TDD-config. a0 and a1 indicate the uplink slot number of the pattern, and a2 and a3 indicate the time offset of the pattern. Since the pattern has 3 uplink slots and a time offset of 0 slots, the values ​​of a0, a1, a2, and a3 are set to 1, 1, 0, and 0, respectively. Therefore, the actual uplink slot number of the pattern is 3 * 2^u_SL = 3 * 2^1 = 6 slots, and the actual offset is 0 * 2^u_SL = 0 * 2^1 = 0 slots. The indicated uplink resource configuration is shown in Table 4 below.

[0119] Table 4:

[0120]

[0121] One embodiment may be as follows:

[0122] According to the SL SCS instructions, the resource configuration is set to two patterns, as follows:

[0123] Assuming the transmitter needs to indicate the configuration as LTE config 6, u_SL = 1 (SL SCS = 30kHz), one implementation is:

[0124] The PSBCH signal is set to 0 for the type indicator bit, indicating the type as LTE. The period of pattern1 = the period of pattern2 = 5ms is pre-configured. The first bit is the 8 MSBs in SL-TDD-config. a0 and a1 indicate the number of uplink time slots in pattern1, a2 and a3 indicate the number of uplink time slots in pattern2, a4 and a5 indicate the time domain offset_1 of pattern1, and a6 and a7 indicate the time domain offset_2 of pattern2. Since pattern1 has 3 uplink time slots and pattern2 has 2 uplink time slots, and pattern1 has a time domain offset of 0 slots and pattern2 has a time domain offset of 1 slot, the values ​​of a0, a1, a2, a3, a4, a5, a6, and a7 are set to 1, 1, 1, 0, 0, 0, 0, 1 respectively. At this point, the actual number of uplink time slots for pattern1 is 3 * 2^u_SL = 3 * 2^1 = 6 slots, the actual number of uplink time slots for pattern2 is 2 * 2^u_SL = 2 * 2^1 = 4 slots, the actual offset1 is 0 * 2^u_SL = 0 * 2^1 = 0 slots, and the actual offset2 is 1 * 2^u_SL = 1 * 2^1 = 2 slots. The indicated uplink resource configuration is shown in Table 5 below.

[0125] Table 5:

[0126]

[0127] Alternatively, if the first bit is 8 bits, its position can be as follows:

[0128] The 8 MSBs of SL-TDD-config, or

[0129] The 8 LSBs of SL-TDD-config, or

[0130] PSBCH's 8 MSBs, or

[0131] The PSBCH has 8 LSBs.

[0132] Furthermore, when the terminal obtains the LTE resource configuration, it can set the first bit of the PBSCH signal or SL-TDD-Config to the number of uplink resources, offset value, period, etc. corresponding to the LTE resource configuration.

[0133] The first bit is 9 bits:

[0134] The first bit indicates the number of uplink resources. Optionally, it may also indicate the offset value and / or period. The offset value and period are obtained by at least one method, such as network configuration, pre-configuration, other user indication, or protocol agreement. If they are pre-configured or agreed upon by the protocol, no indication is required. That is, the indication of the offset value and period is optional.

[0135] One approach is to follow the LTE SCS instructions:

[0136] Configuration splitting treats LTE resource configuration as one or two patterns. For example, considering LTE resource configuration as a 5ms long pattern, assuming the first bit indicates the uplink resource count and offset value, with the period determined by the protocol, the first bit is 4 bits, split into two indication fields: 2 bits indicate the uplink slot count of the pattern, and 2 bits indicate the time domain offset of the pattern. The uplink slot count indication method is as follows:

[0137]

[0138] in, The resource indicator value is 'uslots', where 'uslots' is the number of uplink time slots in the pattern. Indicates the relationship between u slots The floor function, in this embodiment of the application, is rounded down. This indicates the floor function.

[0139] Of course, the above This is merely an example; in some implementations, it could also be... in, Indicates the relationship between u slots It should be noted that the embodiments of this application mainly use rounding down as an example. In the implementation of using rounding down, rounding down can be replaced with rounding up.

[0140] For example, consider LTE resource configuration as two 5ms long patterns. Assume the first bit indicates the uplink resource count and offset value, the period is determined by the protocol, and the uplink resource count for both patterns is a joint indication. The first bit is 9 bits, divided into 3 indication fields: 5 bits jointly indicate the uplink time slot count for pattern 1 and pattern 2, 2 bits indicate the time domain offset_1 for pattern 1, and 2 bits indicate the time domain offset_2 for pattern 2. The uplink time slot count indication method is as follows:

[0141] or

[0142]

[0143] in, For resource indication value, u slots，1 u is the uplink timeslot number in pattern1. slots，2 P1 is the number of uplink time slots in pattern2, P2 is the period of pattern1, and P2 is the period of pattern2.

[0144] When the first bit is 9 bits, the position of the first bit can be as follows:

[0145] The 9 MSBs of SL-TDD-config, or

[0146] The 9 LSBs of SL-TDD-config, or

[0147] PSBCH's 9 MSBs, or

[0148] PSBCH has 9 LSBs.

[0149] One embodiment may be as follows:

[0150] According to the LTE SCS instructions, the resource configuration is 1 pattern:

[0151] Assuming the sender needs to indicate the configuration as LTE config 1, one implementation is:

[0152] The PSBCH signal is configured with the type indicator bit set to 0, indicating LTE as the type. The pattern period is pre-configured at 5ms. The first bit represents the four MSBs in the SL-TDD-config. a0 and a1 indicate the uplink slot number of the pattern, and a2 and a3 indicate the time-domain offset of the pattern. Since the pattern has 2 uplink slots and a time-domain offset of 1 slot, then... Since the time-domain offset of the pattern is 1 slot, the values ​​of a0, a1, a2, and a3 are set to 1, 0, 0, and 1 respectively, indicating the uplink resource configuration as shown in Table 6 below:

[0153] Table 6:

[0154]

[0155] One embodiment may be as follows:

[0156] According to the LTE SCS instructions, the resources are configured with two patterns:

[0157] Assuming the sender needs to indicate the configuration as LTE config 1, one implementation is:

[0158] The PSBCH signal is set to 0 for the type indicator bit, indicating LTE. The period of pattern1 = the period of pattern2 = 5ms is pre-configured. The first bit represents the 9 MSBs in the SL-TDD-config. A0, A1, A2, A3, and A4 jointly indicate the uplink slot number for pattern1 and pattern2. A5 and A6 indicate the time domain offset_1 for pattern1, and A7 and A8 indicate the time domain offset_2 for pattern2. Since the uplink slot number for pattern1 is 2, the uplink slot number for pattern2 is 2, and P2 = 5ms, then... Since the time-domain offset of pattern1 is 1 slot and the time-domain offset of pattern2 is 1 slot, the values ​​of a0, a1, a2, a3, a4, a5, a6, and a7 are set to 0, 1, 1, 1, 0, 0, 1, 0, 1 respectively. The indicated uplink resource configuration is shown in Table 7 below:

[0159] Table 7:

[0160]

[0161] When the first bit is 9 bits, the position of the first bit can be as follows:

[0162] The 9 MSBs of SL-TDD-config, or

[0163] The 9 LSBs of SL-TDD-config, or

[0164] PSBCH's 9 MSBs, or

[0165] PSBCH has 9 LSBs.

[0166] Furthermore, when the terminal obtains the LTE resource configuration, the first bit of the PBSCH signal or SL-TDD-Config can be set to the number of uplink resources corresponding to the LTE resource configuration, and / or the offset value, and / or the period, etc.

[0167] The first bit is 11 bits:

[0168] The first bit indicates the number of uplink resources. Optionally, it may also indicate the offset value and / or period. The offset value and period are obtained by at least one method, such as network configuration, pre-configuration, other user indication, or protocol agreement. If they are pre-configured or agreed upon by the protocol, no indication is required. That is, the indication of the offset value and period is optional.

[0169] One indication method, according to the SL SCS indication, can be as follows:

[0170] Configuration splitting treats LTE resource configuration as one or two patterns.

[0171] For example, consider LTE resource configuration as a 5ms pattern. Assume the first bit indicates the number of uplink resources and the offset value, and the period is determined by the protocol. The first bit is 9 bits, split into two indication fields: 7 bits indicate the number of uplink time slots in the pattern, and 2 bits indicate the time domain offset of the pattern. In this case, the uplink time slot indication method of NR V2X is reused.

[0172] For example, consider LTE resource configuration as two 5ms long patterns. Assume the first bit indicates the uplink resource count and offset value, the period is determined by the protocol, and the uplink resource count for both patterns is a joint indication. The first bit is 11 bits, divided into three indication fields: 7 bits jointly indicate the uplink slot count for pattern 1 and pattern 2, 2 bits indicate the time domain offset_1 for pattern 1, and 2 bits indicate the time domain offset_2 for pattern 2. In this case, the uplink slot count indication method of NR V2X is reused.

[0173] One embodiment may be as follows:

[0174] According to the SL SCS instructions, the resource configuration is set to 1 pattern:

[0175] Assuming the transmitter needs to indicate the configuration as LTE config 1, u_SL = 1 (SL SCS = 30kHz), one implementation is:

[0176] The PSBCH signal is configured with the type indicator bit set to 0, indicating LTE as the type. The pattern period is pre-configured to 5ms. The first bit represents the 9 MSBs in the SL-TDD-config. Bits a0, a1, a2, a3, a4, a5, and a6 indicate the uplink slot number of the pattern, while a7 and a8 indicate the time-domain offset of the pattern. Since the pattern has 2 uplink slots and a time-domain offset of 1 slot, then... If the time-domain offset of the pattern is 1 slot, then the values ​​of a0, a1, a2, a3, a4, a5, a6, a7, and a8 are set to 0, 0, 0, 0, 1, 0, 0, 0, 1 respectively. In this case, the actual number of uplink time slots for the pattern = 2 * 2^u_SL = 4 slots, and the actual offset = 1 * 2^u_SL = 2 slots. The indicated uplink resource configuration is shown in Table 8 below.

[0177] Table 8:

[0178]

[0179] One embodiment may be as follows:

[0180] According to the SL SCS instructions, the resources are configured with two patterns:

[0181] Assuming the transmitter needs to indicate the configuration as LTE config 1, u_SL = 1 (SL SCS = 30kHz), one implementation is:

[0182] The PSBCH signal is set to 0 for the type indicator bit, indicating LTE. The period of pattern1 = the period of pattern2 = 5ms is pre-configured. The first bit is the 11 MSBs in the SL-TDD-config. a0, a1, a2, a3, a4, a5, and a6 jointly indicate the uplink slot number of pattern1 and pattern2. a7 and a8 indicate the time domain offset of pattern1 (offset_1). a9, a... 10 This indicates the time-domain offset of pattern2, offset_2. Since pattern1 has 2 uplink time slots, pattern2 also has 2 uplink time slots, and P2 = 5ms,

[0183] but

[0184] Since the time-domain offset of pattern1 is 1 slot and the time-domain offset of pattern2 is 1 slot, then we set a0, a1, a2, a3, a4, a5, a6, a7, a8, a9, a 10 The values ​​are 0, 1, 1, 0, 0, 0, 0, 0, 1, 0, 1 respectively. At this time, the actual offset_1 = offset_2 = 2 slots, that is, the indicated uplink resource configuration is shown in Table 9 below:

[0185] Table 9:

[0186]

[0187] When the first bit is 11 bits, the position of the first bit can be as follows:

[0188] The 11 MSBs of SL-TDD-config, or

[0189] The 11 LSBs of SL-TDD-config, or

[0190] 11 MSBs of PSBCH, or

[0191] PSBCH 11 LSBs

[0192] Furthermore, when the terminal obtains the LTE resource configuration, it sets the first bit of the PBSCH signal or SL-TDD-Config to the number of uplink resources, and / or offset value, and / or period, etc., corresponding to the LTE resource configuration.

[0193] As an optional implementation, when the first position bit of the first indication information indicates a first preset value, the value of the second position bit of the first indication information is within a third range and is used to indicate the resource configuration index of the transmission resource.

[0194] The first preset value mentioned above can be a protocol agreement, a network-side configuration, or a terminal setting, etc. In this embodiment, the other preset values ​​can also be protocol agreements, network-side configurations, or terminal settings, etc. Furthermore, the third range mentioned above can be a protocol agreement, a network-side configuration, or a terminal setting, etc.

[0195] The first bit, the second bit, and the third bit mentioned above can be found in the previous description, and will not be repeated here.

[0196] In this implementation, the number of resources, offset, and period of the transmission resources can be pre-configured, agreed upon by the protocol, or determined by the terminal.

[0197] As an optional implementation, the second bit of the third position bit of the first indication information is used to indicate at least one of the following:

[0198] Resource quantity, offset, and cycle.

[0199] In this implementation, the number of resources, offset, and period of the transmission resources can be pre-configured, agreed upon by the protocol, or determined by the terminal.

[0200] In this embodiment, the resource configuration index can be pre-configured, agreed upon by the protocol, or determined by the terminal. Of course, it can also be indicated by the second bit mentioned above.

[0201] For example, if the first bit, second bit, and third bit are represented by X, Y, and Z respectively, when X bit indicates 0, the index 9-15 indicated by Y bit can be as follows:

[0202] In one case, at least a portion of the indices 9-15 indicated by the Y bit are used to indicate LTE resource configurations, such as the indices 0-6 of LTE TDD configuration. An example correspondence is shown in Table 10:

[0203] Table 10:

[0204]

[0205]

[0206] In Table 10, optionally, when the LTE resource configuration information obtained by the terminal indicates an LTE TDD config index, Y is set to the value corresponding to that LTE TDD config index.

[0207] One embodiment may be as follows:

[0208] Assuming the transmitter needs to indicate LTE config 5, one implementation is:

[0209] Let a0 = 0, and set the values ​​of a1, a2, a3, and a4 to 1, 1, 1, and 0 respectively, which indicates that the index is 14 and the current configuration index is LTE config 5.

[0210] In another case, at least a portion of indexes 9-15 indicated by the Y bit is used to indicate the indexes of N different resource configurations, for example, N=7; the second bit in Z=7 bits indicates LTE resource information, wherein the indication method can be: the second bit indicates the number of uplink resources, and optionally, it can also indicate the offset value and / or period, wherein the offset value and period are obtained by at least one method such as network configuration, pre-configuration, other user indications or protocol agreement, etc. If it is pre-configured or protocol agreed, no indication is required, that is, the indication of the offset value and period is optional.

[0211] When the second bit is 5 bits:

[0212] According to the LTE SCS instructions, the following can be done:

[0213] Configuration splitting treats LTE resource configuration as one or two patterns.

[0214] For example, considering LTE resource configuration as a 5ms pattern, assuming the second bit indicates the number of uplink resources, and the offset and period are obtained by protocol agreement, the second bit, consisting of 2 bits, is used to indicate the number of uplink time slots in the pattern. The uplink time slot number indication method is as follows:

[0215]

[0216] in, For resource indication value, u slots This represents the number of uplink time slots in the pattern.

[0217] For example, consider LTE resource configuration as two 5ms patterns. Assume the second bit indicates the uplink resource count, the offset and period are obtained by protocol, and the uplink resource count for both patterns is jointly indicated. The second bit is 5 bits, jointly indicating the uplink time slot count for pattern 1 and pattern 2. The uplink time slot count indication method is as follows:

[0218] or

[0219]

[0220] in, For resource indication value, u slots，1 u is the uplink timeslot number in pattern1. slots，2 P1 is the number of uplink time slots in pattern2, P2 is the period of pattern1, and P2 is the period of pattern2.

[0221] One embodiment may be as follows:

[0222] According to the LTE SCS instructions, the resource configuration is 1 pattern:

[0223] Assuming the sender needs to indicate the configuration as LTE config 1, one implementation is:

[0224] Let a0 = 0, the pattern period = 5ms as a pre-configuration, the pattern time offset = 1 slot as a pre-configuration, and the second bit = 2 MSBs in Z, indicating the number of uplink time slots for the pattern. Since the number of uplink time slots for the pattern is 2, then... Therefore, the values ​​of a5 and a6 are set to 1 and 0 respectively, indicating the uplink resource configuration as shown in Table 11 below:

[0225] Table 11:

[0226]

[0227] One embodiment may be as follows:

[0228] According to the LTE SCS instructions, the resources are configured with two patterns:

[0229] Assuming the sender needs to indicate the configuration as LTE config 1, one implementation is:

[0230] Let a0 = 0, the period of pattern1 = the period of pattern2 = 5ms as a pre-configuration, the time domain offset of pattern1 = the time domain offset of pattern2 = 1 slot as a pre-configuration, the second bit is 5 MSBs in Z, a5, a6, a7, a8, a9 jointly indicate the number of uplink time slots of pattern1 and pattern2. Since the number of uplink time slots of pattern1 is 2, the number of uplink time slots of pattern2 is 2, and P2 = 5ms, then... Therefore, the values ​​of a5, a6, a7, a8, and a9 are set to 0, 1, 1, 1, and 0 respectively, indicating the uplink resource configuration as shown in Table 12 below:

[0231] Table 12:

[0232]

[0233] When the second bit is 5 bits, the position of the second bit can be as follows:

[0234] Z's 5 MSBs, or

[0235] Z's 5 LSBs, or

[0236] 5 MSBs of PSBCH, or

[0237] PSBCH's 5 LSBs, or

[0238] The 5 MSBs of SL-TDD-Config, or

[0239] The 5 LSBs of SL-TDD-Config.

[0240] When the second bit is 7 bits, according to the SL SCS instruction:

[0241] Configuration splitting treats LTE resource configuration as one or two patterns.

[0242] For example, if LTE resource configuration is considered as a 5ms pattern, and the second bit indicates the number of uplink resources, with the offset and period determined by the protocol, the second bit is 7 bits. In this case, the uplink slot number indication method of NR V2X can be reused.

[0243] For example, consider LTE resource configuration as two 5ms long patterns. Assume the second bit indicates the uplink resource count, the offset and period are obtained by the protocol, and the uplink resource count of the two patterns is jointly indicated. The second bit is 7 bits, jointly indicating the uplink slot count of pattern1 and pattern2. In this case, the uplink slot count indication method of NR V2X is reused.

[0244] One embodiment may be as follows:

[0245] According to the SL SCS instructions, the resource configuration is set to 1 pattern:

[0246] Assuming the transmitter needs to indicate the configuration as LTE config 1, u_SL = 1 (SL SCS = 30kHz), one implementation is:

[0247] Let a0 = 0, the pattern period = 5ms as a pre-configuration, the pattern time offset = 1 slot as a pre-configuration, the second bit is 7 bits of Z, a5, a6, a7, a8, a9, a 10 a 11 The uplink timeslot number of the pattern is indicated. Since the uplink timeslot number of the pattern is 2, then... Then set a5, a6, a7, a8, a9, a 10 a 11 The values ​​are 0, 0, 0, 0, 1, 0, 0 respectively. At this time, the actual number of uplink time slots for the pattern is 2 * 2^u_SL = 4 slots, and the actual offset is 1 * 2^u_SL = 2 slots. That is, the indicated uplink resource configuration is shown in Table 13 below:

[0248] Table 13:

[0249]

[0250] One embodiment may be as follows:

[0251] According to the SL SCS instructions, the resources are configured with two patterns:

[0252] Assuming the transmitter needs to indicate the configuration as LTE config 1, u_SL = 1 (SL SCS = 30kHz), one implementation is:

[0253] Let a0 = 0, the period of pattern1 = the period of pattern2 = 5ms as a pre-configuration, the time domain offset of pattern = the time domain offset of pattern2 = 1 slot as a pre-configuration, the second bit is 7 bits of Z, a5, a6, a7, a8, a9, a 10 a 11 The uplink timeslot number is jointly specified for pattern1 and pattern2. Since pattern1 has 2 uplink timeslots, pattern2 also has 2 uplink timeslots.

[0254] And P2 = 5ms, then

[0255] Then set a5, a6, a7, a8, a9, a 10 a 11 The values ​​are 0, 1, 1, 0, 0, 0, 0 respectively. At this time, the actual offset_1 = offset_2 = 2 slots, that is, the indicated uplink resource configuration is shown in Table 14 below:

[0256] Table 14:

[0257]

[0258] When the second bit is 7 bits, the position of the second bit can be as follows:

[0259] Z's 7 bits

[0260] PSBCH's 7 MSBs, or

[0261] PSBCH's 7 LSBs, or

[0262] The 7 MSBs of SL-TDD-Config, or

[0263] The 7 LSBs of SL-TDD-Config.

[0264] Furthermore, when the terminal obtains the LTE resource configuration, the second bit in Z can be set to the number of uplink resources, offset value, period, etc. corresponding to the LTE resource configuration.

[0265] In another case, at least a portion of indexes 9-14 indicated by Y bit is used to indicate the indexes of N different resource configurations, for example, N=6; Z=7 bits indicate LTE resource information, wherein the indication method can be: Z indicates the number of uplink resources, and optionally, offset value and / or period can also be indicated, wherein the offset value and period are obtained by at least one method such as network configuration, pre-configuration, other user indication or protocol agreement, etc. If it is pre-configured or protocol agreed, no indication is required, that is, the indication of offset value and period is optional.

[0266] For example, resource information indicating LTE TDD config 0-5 can be indicated in the following two ways:

[0267] I. In accordance with LTE SCS instructions:

[0268] Configuration splitting treats LTE resource configuration as one or two patterns. For example, LTE resource configuration can be considered as two 5ms long patterns. Assuming Z = 7 bits indicating the uplink resource count and offset value, the period is obtained by protocol agreement, and the time domain offsets of pattern1 and pattern2 are the same, the uplink resource count of the two patterns is jointly indicated. 2 bits are used to indicate the offset, and 5 bits jointly indicate the uplink time slot count of pattern1 and pattern2. The uplink time slot count indication method is as follows:

[0269] or

[0270]

[0271] in, For resource indication value, u slots，1 u is the uplink timeslot number in pattern1. slots，2 P1 is the number of uplink time slots in pattern2, P2 is the period of pattern1, and P2 is the period of pattern2.

[0272] II. In accordance with SL SCS instructions:

[0273] The configuration is split, treating LTE resource configuration as one or two patterns. For example, LTE resource configuration can be considered as two 5ms long patterns, assuming Z = 7 bits indicating the number of uplink resources. The offset value and period are obtained by the protocol, and the time domain offsets of pattern 1 and pattern 2 are the same. The uplink resource number of the two patterns is jointly indicated. In this case, the uplink slot number indication method of NRV2X is reused.

[0274] Furthermore, when the terminal obtains the LTE resource configuration, Z can be set to the number of uplink resources corresponding to the LTE resource configuration, and / or the offset value, and / or the period, etc.

[0275] One embodiment may be as follows:

[0276] According to the LTE SCS instructions, the resources are configured with two patterns:

[0277] Assuming the sender needs to indicate the configuration as LTE config 1, one implementation is:

[0278] Let a0 = 0, the period of pattern1 = the period of pattern2 = 5ms as a pre-configured value. The 7 bits of Z indicate the number of uplink time slots and the time domain offset. At this point, the time domain offset values ​​of the two patterns are the same, and the number of uplink time slots is a joint indicator, i.e., a5, a6, a7, a8, and a9 jointly indicate the number of uplink time slots for pattern1 and pattern2. 10 a 11 The time-domain offset value is indicated. Since pattern 1 has 2 uplink time slots and pattern 2 has 2 uplink time slots, and P2 = 5ms,

[0279] but

[0280] Since the time-domain offset value is 1 slot, we set a5, a6, a7, a8, a9, a 10 a 11 The values ​​are 0, 1, 1, 1, 0, 0, 1, which indicate the uplink resource configuration as shown in Table 15 below:

[0281] Table 15:

[0282]

[0283] One embodiment may be as follows:

[0284] According to the SL SCS instructions, the resources are configured with two patterns:

[0285] Assuming the transmitter needs to indicate the configuration as LTE config 1, u_SL = 1 (SL SCS = 30kHz), one implementation is:

[0286] Let a0 = 0, the period of pattern1 = the period of pattern2 = 5ms as a pre-configuration, the time domain offset of pattern1 = the time domain offset of pattern2 = 1 slot as a pre-configuration, and the 7 bits of Z jointly indicate the number of uplink time slots, i.e., a5, a6, a7, a8, a9, a 10 a11 The uplink timeslots of pattern1 and pattern2 are jointly indicated. Since pattern1 has 2 uplink timeslots and pattern2 has 2 uplink timeslots, and P2 = 5ms,

[0287] but

[0288] Then set a5, a6, a7, a8, a9, a 10 a 11 The values ​​are 0, 1, 1, 0, 0, 0, 0 respectively. At this time, the actual offset_1 = offset_2 = 2 slots, that is, the indicated uplink resource configuration is shown in Table 16 below:

[0289] Table 16:

[0290]

[0291] As an optional implementation, the third bit of the first indication information is used to indicate the resource configuration index of the transmission resource.

[0292] This implementation may use part or all of the code points in the third position bit to indicate the resource configuration index of the transmission resource.

[0293] For example, when the value of the third bit of the first indication information is within the fourth range, it is used to indicate the resource configuration index of the transmission resource.

[0294] The fourth scope mentioned above can be pre-configured, agreed upon in a protocol, etc.

[0295] For example, at least some of the codepoints 121-127 indicated by the Z bit are used to indicate the index of the LTE configuration, and an example correspondence is shown in Table 17:

[0296] Table 17:

[0297]

[0298]

[0299] Furthermore, in one implementation, the first position bit and the second position bit of the first indication information may not carry valid information, for example: X+Y=5 bits do not carry valid information.

[0300] One embodiment may be as follows:

[0301] Assuming the sender needs to indicate the configuration as LTE config 1, one implementation is:

[0302] X+Y = 5 bits do not carry valid information. Set the values ​​of a_5, a_6, a_7, a_8, a_9, a_10, and a_11 to 1, 1, 1, 1, 0, 1, 0 respectively, which indicates that the index is 122 and the current configuration index is LTE config 1.

[0303] In another implementation, at least one of the first position bits and the second position bits of the first indication information is used to indicate at least one of the following:

[0304] Resource quantity, offset, and cycle.

[0305] In other words, at least one of X and Y carries valid information, such as indicating the TDD configuration cycle and the number of patterns. For example, X indicates the number of patterns, and / or Y indicates the cycle.

[0306] Furthermore, when the LTE resource configuration information obtained by the terminal indicates the LTE TDD config index, Z can be set to the value corresponding to the LTE TDD config index.

[0307] It should be noted that the method of indicating resources in the above embodiments can refer to the above embodiments, for example:

[0308] At least a portion of codepoints 121-127 indicated by the Z bit are used to indicate the indexes of N different resource configurations, for example, N=7. The indication method can be: X+Y indicates the number of uplink resources. Optionally, an offset value and / or period can also be indicated, wherein the offset value and period are obtained by at least one method such as network configuration, pre-configuration, other user indication, or protocol agreement. If it is pre-configured or protocol agreed, no indication is required, that is, the indication of the offset value and period is optional.

[0309] Among them, X+Y=5 bits indicate that resource information can be indicated according to LTE SCS:

[0310] Configuration splitting treats LTE resource configuration as one or two patterns.

[0311] For example, considering LTE resource configuration as a 5ms pattern, assuming X+Y indicates the number of uplink resources, and the offset and period are obtained by protocol agreement, the uplink slot number indication method is as follows:

[0312]

[0313] in, For resource indication value, u slots This represents the number of uplink time slots in the pattern.

[0314] For example, consider LTE resource configuration as two 5ms patterns. Assume X+Y indicates the uplink resource count, the offset and period are obtained by protocol agreement, and the uplink resource count of the two patterns is a joint indication. The uplink slot count indication method is as follows:

[0315] or

[0316]

[0317] in, For resource indication value, u slots，1 u is the uplink timeslot number in pattern1. slots，2 P1 is the number of uplink time slots in pattern2, P2 is the period of pattern1, and P2 is the period of pattern2.

[0318] Furthermore, when the terminal obtains the LTE resource configuration, X+Y can be set to the number of uplink resources corresponding to the LTE resource configuration, and / or the offset value, and / or the period, etc.

[0319] One embodiment may be as follows:

[0320] According to the LTE SCS instructions, the resource configuration is 1 pattern:

[0321] Assuming the sender needs to indicate the configuration as LTE config 1, one implementation is:

[0322] Let a0, a1, a2, a3, and a4 indicate the number of uplink time slots for the pattern. The pattern period of 5ms is a pre-configured value, and the pattern time offset of 1 slot is also a pre-configured value. Since the pattern has 2 uplink time slots, then... Therefore, the values ​​of a0, a1, a2, a3, and a4 are set to 0, 0, 0, 1, and 0 respectively (at this time, a5, a6, a7, a8, a9, and a... are still set). 10 a 11 The values ​​are 1, 1, 1, 1, 0, 1, 0, but only indicate index 122 and have no corresponding relationship with LTEconfig (this needs to be distinguished from Example 8). That is, the indicated uplink resource configuration is shown in Table 18 below:

[0323] Table 18:

[0324]

[0325] One embodiment may be as follows:

[0326] According to the LTE SCS instructions, the resources are configured with 2 patterns.

[0327] Assuming the sender needs to indicate the configuration as LTE config 1, one implementation is:

[0328] Let a0, a1, a2, a3, and a4 jointly indicate the number of uplink time slots for pattern1 and pattern2. The pre-configured period of pattern1 = period of pattern2 = 5ms, and the pre-configured time-domain offset of pattern1 = time-domain offset of pattern2 = 1 slot. Since the number of uplink time slots for pattern1 is 2, the number of uplink time slots for pattern2 is 2, and P2 = 5ms, then... Therefore, the values ​​of a5, a6, a7, a8, and a9 are set to 0, 1, 1, 1, and 0 respectively (at this point, the values ​​of a5, a6, a7, a8, a9, and a are still set to 0, 1, 1, 1, and 0 respectively). 10 a 11 The values ​​are 1, 1, 1, 1, 0, 1, 0, but only indicate index 122 and have no corresponding relationship with LTE config (this needs to be distinguished from Example 8). That is, the indicated uplink resource configuration is shown in Table 19 below:

[0329] Table 19:

[0330]

[0331] As an optional implementation, the transmission resources indicated by the first indication information are transmission resources corresponding to a portion of the resource configurations supported by the terminal.

[0332] The aforementioned transmission resources refer to a portion of the resource configurations supported by the terminal. This can be understood as the first indication information indicating only a portion of the resource configurations supported by the terminal, thus limiting the transmission resources that the first indication information can indicate. This ensures that the PSBCH signal avoids impacting other resources when dealing with uplink and downlink resources.

[0333] For example, restricting the LTE resource configuration indicated by the PSBCH signal supporting NR SL can specifically mean limiting the PSBCH signal to indicate only at least one of LTE config 0-3 and FDD, i.e., not supporting LTE TDD config 4-6. If the configured or pre-configured LTE resource configuration is LTE TDD config 4-6, then NR SL transmission is performed, or NR SL is scheduled or configured through the LTE base station. In other words, if the LTE network-side equipment provides NR SL configuration, then the LTE configuration is either LTE TDD config 0-3 or LTE FDD. For example, the LTE config 0-3 configuration can be split into two patterns, as shown in Table 20:

[0334] Table 20:

[0335] Configuration index P1 (ms) P2 (ms) 0 4 1 1 4 1 2 3 2 3 5 5

[0336] In this embodiment, the resource indication method may include the following indication methods:

[0337] 1. According to the LTE SCS instructions, the specific details are as follows:

[0338] or

[0339]

[0340] in, For resource indication value, u slots，1 u is the uplink timeslot number in pattern1. slots，2 P1 is the number of uplink time slots in pattern2, P2 is the period of pattern1, and P2 is the period of pattern2.

[0341] 2. According to the SL SCS instruction, where the SL SCS instruction can be the formula for reusing NR device to everything (V2X) uplink time slot instruction, which will not be explained in detail here.

[0342] One embodiment may be as follows:

[0343] According to the LTE SCS instruction, assuming the configuration that the transmitter needs to indicate is LTE config 1, one implementation method is:

[0344] Let a0 = 1. Consider LTE config 1 as P1 + P2 = 4ms + 1ms. Then, set the values ​​of a1, a2, a3, and a4 to 1, 1, 0, and 1 respectively, meaning the value of Y indicates 13. The periods of pattern 1 and pattern 2 are pre-configured. Since the uplink slot count for pattern 1 is 2, the uplink slot count for pattern 2 is 0, and P2 = 1ms, then... Therefore, we set a5, a6, a7, a8, a9, a 10 a 11 The values ​​are 0, 0, 0, 0, 1, 0, 0 respectively, indicating the uplink resource configuration as shown in Table 21 below:

[0345] Table 21:

[0346]

[0347] One embodiment may be as follows:

[0348] According to the SL SCS instruction, assuming the transmitter needs to indicate the configuration as LTE config 1, u_SL = 1 (SL SCS = 30kHz), one implementation method is:

[0349] Let a0 = 1. Considering LTE config 1 as P1 + P2 = 4ms + 1ms, then the values ​​of a1, a2, a3, and a4 are set to 1, 1, 0, and 1 respectively. This means the value indicated by Y is 13. The periods of pattern 1 and pattern 2 are pre-configured. Since the uplink slot count of pattern 1 is 2, and the uplink slot count of pattern 2 is 0, and P2 = 1ms,

[0350] but

[0351] Therefore, we set a5, a6, a7, a8, a9, a 10 a 11 The values ​​are 0, 0, 0, 1, 1, 0, 0 respectively, indicating the uplink resource configuration as shown in Table 22 below:

[0352] Table 22:

[0353]

[0354] As an optional implementation, the PSBCH signal further includes third indication information, which indicates whether the mode of the transmission resource is FDD or TDD; or

[0355] The first indication information is used to indicate that the transmission resource is an FDD transmission resource.

[0356] For example, the third indication information is 1 bit, that is, 1 bit in the PSBCH signal is used to indicate FDD or TDD.

[0357] When the first indication information indicates the second preset value, it can indicate that the mode of the transmission resource is FDD.

[0358] For example: Use SL-TDD-config to indicate FDD resource information. When SL-TDD-config indicates the first preset value, it means that the current state is FDD. If all bits of SL-TDD-config are 1 or all bits are 0, it means that the current state is FDD.

[0359] One embodiment may be as follows:

[0360] Set the values ​​of a_0, a_1, a_2, a_3, a_4, a_5, a_6, a_7, a8, a_8, a_10, and a_11 in SL-TDD-config to 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, indicating that the current mode is FDD.

[0361] Alternatively, when a portion of the bits in the first indication information indicates a third preset value, it can represent that the mode of the transmission resource is FDD.

[0362] The aforementioned bits can be first position bits, second position bits, or third position bits, etc. For example, when at least some bits of SL-TDD-config indicate the second preset value, it means that the current value is FDD. For example, when all bits corresponding to Z=7 bits are set to 1 or all bits are set to 0, it means that the current value is FDD.

[0363] Furthermore, when the aforementioned bits are the third bit, X+Y does not carry valid information. The period of the FDD mode is obtained through pre-configuration or protocol agreement, and the selectable period is...

[0364] 1ms, or 2ms, or 5ms, or 10ms.

[0365] Alternatively, when a portion of the bits in the first indication information indicates a third preset value, signifying that the mode of the transmission resource is FDD, all or part of the remaining bits in the first indication information are used to indicate the period of the transmission resource; or

[0366] The period of the transmission resources is pre-configured or agreed upon by the protocol.

[0367] For example, at least one of X and Y carries valid information, such as X+Y jointly indicating the FDD period, or the value indicated by X+Y is a period value (time slot, second, millisecond, microsecond, subframe number or frame number), such as 1ms, 2ms, 5ms or 10ms.

[0368] Alternatively, Y can indicate the FDD period, or the value indicated by Y can be a period value (time slot, second, millisecond, microsecond, subframe number, or frame number), for example, 1ms, 2ms, 5ms, or 10ms.

[0369] Alternatively, Y could indicate the index corresponding to the period.

[0370] One embodiment may be as follows:

[0371] In one scenario, the X+Y joint indication period can be as follows:

[0372] Let SL-TDD-config's a5, a6, a7, a8, a8, a 10 a 11 The values ​​are 0, 0, 0, 0, 0, 0, 0, indicating that the current mode is FDD. Assuming the period is 10ms, let a0, a1, a2, a3, and a4 carry valid information, and let the indicated value be the period value. Then set the values ​​of a0, a1, a2, a3, and a4 to 0, 1, 0, 1, and 0, respectively.

[0373] In one scenario, Y indicates the period, specifically as follows:

[0374] Let SL-TDD-config's a5, a6, a7, a8, a8, a 10 a 11 The values ​​are 0, 0, 0, 0, 0, 0, 0, indicating that the current mode is FDD. Assuming the period is 10ms, let a1, a2, a3, and a4 carry valid information, and let the value indicate the index corresponding to the period (at this time, the correspondence between the period and the index is pre-configured). Then set the values ​​of a1, a2, a3, and a4 to 0, 1, 0, and 0, respectively.

[0375] As an optional implementation, when the transmission resources are determined through pre-configuration, the terminal is pre-configured with resource configurations for a first network type and a second network type, and the PSBCH signal is determined based on one of the resource configurations for the first network type and the second network type.

[0376] The aforementioned transmission resources can be determined through pre-configuration, meaning that the transmission resources are pre-configured, for example, the network side pre-configures the transmission resources for the terminal or the terminal itself pre-configures the transmission resources. Specifically, it can be a resource configuration resource for pre-configured transmission resources.

[0377] The resource configuration for the first network type mentioned above can be resource configuration information for transmission resources belonging to the first network type, such as at least one of the following: a resource configuration index, a pattern indicating resource status, a pattern indicating the number of resources, a pattern indicating offset, and a pattern indicating period. Similarly, the resource configuration for the second network type mentioned above can be resource configuration information for transmission resources belonging to the second network type.

[0378] When the terminal is pre-configured with resource configurations for a first network type and a second network type, the following scheme may be included:

[0379] If the terminal's operating frequency domain belongs to the frequency domain of the first network type, then the PSBCH signal is determined based on the resource configuration of the first network type; or

[0380] If the terminal's operating frequency domain belongs to the frequency domain of the second network type, then the PSBCH signal is determined based on the resource configuration of the second network type; or

[0381] If an instruction message indicating the use of resources of the first network type is received, the PSBCH signal is determined based on the resource configuration of the first network type; or

[0382] If an instruction message indicating the use of resources of the second network type is received, the PSBCH signal is determined based on the resource configuration of the second network type.

[0383] The operating frequency domain of the aforementioned terminal can refer to the frequency band, carrier, or frequency of the terminal SL.

[0384] The PSBCH signal can be determined based on the resource configuration of the first network type, which may involve selecting a transmission resource belonging to the first network type based on the resource configuration of the first network type, and generating the PSBCH signal based on the selected transmission resource. Alternatively, the PSBCH signal can be determined based on the resource configuration of the second network type, which may involve selecting a transmission resource belonging to the second network type based on the resource configuration of the second network type, and generating the PSBCH signal based on the selected transmission resource.

[0385] In addition, when the transmission resources are determined through pre-configuration, the terminal is pre-configured with resource configurations for a first network type and a second network type. The resource pool corresponding to the terminal can also be determined based on one of the resource configurations for the first network type and the second network type.

[0386] Whether the resource pool corresponding to the aforementioned terminal is configured based on the resource configuration of the first network type or the resource configuration of the second network type can be found in the determination method of the PSBCH signal mentioned above, which will not be elaborated here.

[0387] For example, when an end user obtains pre-configured resource configuration information, which includes LTE resource configuration and NR resource configuration, such as LTE TDD config and NR TDD config, the terminal can determine the PSBCH content and / or resource pool based on either the LTE resource configuration (e.g., LTE TDD config, subframe allocation) or the NR resource configuration (e.g., TDD-UL-DL config common). Specifically, this can be done as follows:

[0388] I. Determination based on SL band, carrier, or frequency:

[0389] Assuming the terminal performs SL communication in the LTE SL band, carrier, or frequency, or in the LTE Uu band, carrier, or frequency, or in a band, carrier, or frequency where LTE base stations can be deployed, the PSBCH and / or resource pool are determined through LTE resource configuration.

[0390] Alternatively, assuming the terminal is performing SL communication in the NR SL band, carrier, or frequency, or in the NR Uu band, carrier, or frequency, or in a band, carrier, or frequency where NR base stations can be deployed, the PSBCH and / or resource pool are determined through NR resource configuration.

[0391] II. Determining based on the received PSBCH:

[0392] If the received PSBCH indicates LTE configuration resources, then the PSBCH and / or resource pool are determined through LTE resource configuration.

[0393] If the PSBCH received from the synchronization reference user indicates LTE configuration resources, then the PSBCH and / or resource pool are determined through LTE resource configuration.

[0394] If the received PSBCH indicates NR configuration resources, then the PSBCH and / or resource pool are determined through NR resource configuration.

[0395] If the PSBCH received from the synchronization reference user indicates NR configuration resources, then the PSBCH and / or resource pool are determined through NR resource configuration.

[0396] As an optional implementation, when the transmission resources are determined through pre-configuration, the terminal is pre-configured with resource configuration for a first network type, and the PSBCH signal is determined based on the resource configuration for the first network type.

[0397] The first network type mentioned above can be LTE or NR. In this application embodiment, LTE is used as an example for illustration.

[0398] In addition, when the transmission resources are determined through pre-configuration, the terminal is pre-configured with resource configuration of the first network type, and the resource pool corresponding to the terminal can also be determined based on the resource configuration of the first network type.

[0399] For example, the end user obtains the pre-configured resource configuration information, which includes only LTE resource configuration (e.g., LTE TDD config, subframeasseigment) or NR resource configuration (e.g., TDD-UL-DL configcommon).

[0400] Pre-configuration provides only LTE resource configuration when at least one of the following conditions is met:

[0401] If the pre-configured terminal performs SL communication in the LTE SL band, carrier, or frequency, or in the LTE Uu band, carrier, or frequency, or in a band, carrier, or frequency where an LTE base station can be deployed, then the pre-configuration only provides LTE resource configuration.

[0402] Pre-configuration provides only NR resource configuration when at least one of the following conditions is met:

[0403] If the UE is pre-configured to perform SL communication in the NR SL band, carrier, or frequency; or in the NR Uu band, carrier, or frequency where NR base stations can be deployed, then the pre-configuration only provides NR resource configuration; or

[0404] If the pre-configured terminal does not support using an eNB as a synchronization source, then the pre-configuration only provides NR resource configuration.

[0405] As an optional implementation, the pre-configured resource settings of the terminal are associated with the type of the terminal.

[0406] For example: Suppose that a first type of terminal can search for at least one of gNB, GNSS and SyncRef UE as a synchronization reference, and a second type of terminal can search for at least one of eNB and gNB, GNSS and SyncRef UE as a synchronization reference. The pre-configuration information of the first type of terminal includes at least NR resource configuration, and the pre-configuration information of the second type of terminal includes at least one of LTE resource configuration and NR resource configuration.

[0407] Here, SyncRef UE can refer to a terminal that can be used as a synchronization reference.

[0408] As an optional implementation, the terminal is pre-configured with at least one of the following: the first indication information indicating the transmission resource:

[0409] Resource configuration index, pattern indicating resource status, pattern indicating resource quantity, pattern indicating offset, pattern indicating period.

[0410] The resource configuration index mentioned above can be a TDD config index, such as an LTE TDD config index.

[0411] The above-mentioned pattern indicating resource status can be a pattern that treats resource configuration as a periodic pattern. For example, LTE TDD configuration can be treated as a pattern with a period of 10ms. A 10-bit long bitmap can be used, with each bit indicating the resource status of an LTE time slot. A value of 1 indicates uplink resources and a value of 0 indicates non-uplink resources.

[0412] By using the aforementioned patterns indicating resource count, offset, and period, the terminal can determine how to indicate resource count, offset, and period via PSBCH under these patterns. For example, considering the LTE TDD configuration as pattern 1 with a period of 5ms and pattern 2 with a period of 5ms, an 8-bit bitmap is used, where 2 bits are used to indicate the uplink time slot number of pattern 1, 2 bits are used to indicate the uplink time slot number of pattern 2, 2 bits are used to indicate the time domain offset_1 of pattern 1, and 2 bits are used to indicate the time domain offset_2 of pattern 2.

[0413] For example, consider the LTE TDD configuration as pattern1 with a period of 5ms and pattern2 with a period of 5ms. Use a 9-bit bitmap, where 5 bits jointly indicate the uplink slot number of pattern1 and pattern2, 2 bits are used to indicate the time domain offset_1 of pattern1, and 2 bits are used to indicate the time domain offset_2 of pattern2.

[0414] As an optional implementation, when the terminal receives the resource configuration configured by the network side, the resource configuration of the transmission resource indicated by the first indication information corresponds to the resource configuration configured by the network side.

[0415] The correspondence between the resource configuration of the transmission resource indicated by the first indication information and the resource configuration configured on the network side can be that the resource configuration configured on the network side is set to the resource configuration of the transmission resource.

[0416] For example, when a terminal obtains the LTE resource configuration, it can set the first bit in PBSCH or SL-TDD-Config to the uplink resource number, offset value, and / or period corresponding to the LTE resource configuration.

[0417] In this embodiment, a PSBCH signal is generated. The PSBCH signal includes first indication information, which indicates transmission resources, including at least one of uplink resources and downlink resources. This allows the PSBCH signal to indicate at least one of uplink and downlink resources, thereby improving Sidelink's resource configuration capabilities. Taking LTE uplink resources as an example, this application designs the encoding and indication method of the parameter SL-TDD-Config so that, in addition to indicating NR uplink resources, it further indicates LTE uplink resource configuration. This enables NR SL terminals within the coverage area in LTE V2X communication to transmit uplink resource configuration information to NR SL terminals outside the coverage area via the PSBCH.

[0418] Please see Figure 3 , Figure 3 This application provides a PSBCH signal generation device, which is applied to a terminal, such as... Figure 3 As shown, the PSBCH signal generation device 300 includes:
