Description

Technical Field

[0001] The present invention relates to the field of wireless communication technologies, and particularly to a method, a communication device, and a storage medium for transmitting sidelink resource indication information. Background Art

[0002] The current Time Division Duplex (TDD) configuration of the New Radio (NR) is very flexible. The number of uplink resources in a TDD pattern can be from 0 to 80, and a TDD configuration may include 1 or 2 TDD patterns. The period of a TDD pattern can be one of 9 types. The periods (P1 and P2) of two TDD patterns may be the same or different.

[0003] NR Sidelink (SL) currently supports 15 / 30 / 60 / 120 kHz. When the sidelink subcarrier spacing (SCS) = 15 / 30 / 60 / 120 kHz, 1 millisecond (ms) corresponds to one time slot (slot), two slots, 4 slots, and 8 slots respectively.

[0004] The disadvantage of the prior art is that the number of bits available for indicating the sidelink time division duplex configuration (TDD configuration) is limited currently, so it is not possible to ensure a high indication accuracy for SL-TDD-config. Summary of the Invention

[0005] The present invention provides a method, a communication device, and a storage medium for transmitting sidelink resource indication information, so as to solve the problem of low indication accuracy when the number of bits for indicating the available resources is insufficient in the prior art.

[0006] In a first aspect, an embodiment of the present invention provides a method for transmitting sidelink resource indication information, including:

[0007] Transmitting sidelink resource indication information, where the indication information includes at least one of first information indicating the number of indication modes and mode period configuration, and second information indicating available resources.

[0009] A transmission module for transmitting sidelink resource indication information, where the indication information includes at least one of first information indicating the number of indication modes and mode period configuration, and second information indicating available resources.

[0010] In a third aspect, an embodiment of the present invention provides a communication device, including a memory, a processor, and a computer program stored on the memory and executable on the processor. When the processor executes the computer program, the method for transmitting sidelink resource indication information described above is implemented.

[0011] In a fourth aspect, an embodiment of the present invention provides a computer-readable storage medium storing a computer program for executing the method for transmitting sidelink resource indication information described above.

[0012] The beneficial effects of the present invention are as follows:

[0013] In the technical solution provided by the embodiment of the present invention, the indication information includes at least one of first information indicating the number of indication modes and mode period configuration, and second information indicating available resources. The first information is used to indicate the number of patterns and pattern period configuration, and the second information is used to indicate available resources.

[0014] Furthermore, by designing the bit encoding method in the parameter SL-TDD-Config: separate encoding or joint encoding, and the indication method: joint indication or segmented indication, while indicating the number of available resources, the parameter can ensure a relatively high indication accuracy as much as possible, enabling the parameter SL-TDD-Config to indicate the available resources of different TDD patterns under different SCSs with a relatively high indication accuracy.

[0019] To facilitate the understanding of the embodiments of the present invention, the following technical points are first introduced:

[0020] 1. NR TDD:

[0021] The current NR TDD configuration is very flexible. The number of uplink resources in a TDD pattern can range from 0 to 80, and a TDD configuration may contain 1 or 2 TDD patterns. The period of a TDD pattern can be one of 9 types. The periods (P1 and P2) of two TDD patterns may be the same or different, as shown in Tables 1 to 3.

[0022] NR SL currently supports 15 / 30 / 60 / 120 kHz. When SCS = 15 / 30 / 60 / 120 kHz, 1 ms corresponds to one slot, two slots, 4 slots, and 8 slots respectively.

[0023] In addition, the number of slots used for SL synchronization signal transmission is also very flexible. One synchronization resource contains 1 to 64 slots for sidelink SSB transmission.

[0032] 2: Introduction to X, Y, and Z:

[0033] The TDD configuration indication in the NR vehicle-to-everything network is as follows:

[0034] X bits to indicate patterns + Y bits to indicate periodicity + Z bits to indicate UL slots.

[0035] 1) Separate encoding indication for X and Y:

[0036] The X bit indicates the pattern type, that is, whether the current TDD configuration contains 1 or 2 patterns; the Y bit indicates the corresponding TDD mode period configuration under the current pattern. For example, X = 1 bit is used to indicate the pattern type. When the TDD configuration contains 1 pattern, there are 9 TDD mode period configurations in total, and Y = 4 bits can be used to indicate the mode period configuration. When the TDD configuration contains 2 patterns, there are 16 TDD mode period configurations in total, and Y = 4 bits can also be used to indicate the mode period configuration.

[0037] 2) Joint encoding indication for X and Y:

[0038] A total of (X + Y) bits are used to indicate the TDD mode period configuration. For example, X + Y = 5 bits, and there are 25 mode period configurations in total, which can be indicated jointly by 5 bits.

[0039] 3) The Z bit is used to indicate the number of available resources within the corresponding TDD pattern period configuration.

[0040] For sidelink, the Long Term Evolution (LTE) system supports sidelink (which can also be translated as side link, edge link, etc.) for direct data transmission between User Equipment (UE) without going through network devices.

[0041] The UE sends sidelink control information (SCI) through the Physical Sidelink Control Channel (PSCCH) to schedule the transmission of the Physical Sidelink Shared Channel (PSSCH) to send data. This transmission is in broadcast form, and the receiving end does not feedback to the sending end whether the reception is successful.

[0042] LTE sidelink design supports two resource allocation modes, namely the scheduled resource allocation mode -1 (commonly known as mode-1) and the autonomous resource selection mode. The former is controlled by the network-side device and allocates resources for each UE, while the latter allows the UE to select resources autonomously.

[0043] LTE supports sidelink Carrier Aggregation (CA). Different from the Uu interface, there is no distinction between the Primary Component Carrier (PCC) and the Secondary Component Carrier (SCC) in LTE sidelink CA. UEs in the autonomous resource selection mode perform resource sensing and resource reservation independently on each CC.

[0044] The design of LTE sidelink is applicable to specific public safety scenarios (such as emergency communication in fire or earthquake disaster areas), or vehicle-to-everything (V2X) communication, etc. V2X communication includes various services, such as basic safety communication, advanced (automatic) driving, platooning, sensor extension, and so on. Since LTE sidelink only supports broadcast communication, it is mainly used for basic safety communication, and other advanced V2X services will be supported by NR sidelink.

[0045] The 5G NR system can be used in operating frequency bands above 6 GHz that are not supported by LTE, supports a larger operating bandwidth, and the NR system also supports Sidelink interface communication for direct communication between terminals.

[0046] Currently, sidelink transmission mainly includes several forms: broadcast, multicast, and unicast. As the name implies, unicast is one-to-one transmission, multicast is one-to-many transmission, and broadcast is also one-to-many transmission, but there is no concept that UEs belong to the same group in broadcast.

[0047] The Physical Sidelink Control Channel (PSCCH) on the sidelink carries the Scheduling Control Information (SCI), and the SCI is used to schedule the Physical Sidelink Shared Channel (PSSCH). The SCI can indicate transmission resources and reserve these resources for future transmissions. The Physical Sidelink Feedback Channel (PSFCH) is used to feedback sidelink Hybrid Automatic Repeat reQuest ACKnowledgement (HARQ-ACK) information. After the user determines the sidelink HARQ information, the sidelink HARQ information can be further sent to the base station through the Physical Uplink Control Channel (PUCCH) or the Physical Uplink Shared Channel (PUSCH).

[0048] The disadvantage of the prior art is that currently, the number of bits in the Sidelink Master Information Block (MIB) that can be used to indicate the TDD configuration is limited. However, there are a total of 25 periodic configurations that need to be indicated, and each periodic configuration involves different Subcarrier Spacings (SCS), so the number of bits used to indicate the SL-TDD-config is limited. Therefore, it is necessary to design the bit encoding and indication method in the SL-TDD-Config so that while indicating the available resources, the highest possible indication accuracy can be ensured as much as possible.

[0049] That is, in sidelink communication, when the TDD configuration includes two TDD patterns, P1 and P2, the number of bits in the parameter SL-TDD-Config is insufficient to indicate the number of available resources. Therefore, it is necessary to design the bit encoding and indication method in the SL-TDD-Config so that while indicating the available resources, the highest possible indication accuracy can be ensured as much as possible. Based on this, an embodiment of the present invention provides a transmission scheme for configuration indication information. It is easy to understand that this scheme can be at least used for LTE sidelink, NR sidelink, and their evolved technologies. The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0050] Figure 1 It is a schematic flowchart of the method for transmitting sidelink resource indication information. As shown in the figure, it may include:

[0051] Step 101: Transmit sidelink resource indication information, where the indication information includes at least one of the first information indicating the number of indication modes and the mode periodic configuration, and the second information indicating the available resources.

[0052] The following will first give an overall description and then examples for illustration.

[0053] In specific implementation, for the sidelink resource indication information, for the terminal, it can send or receive this information, and for network-side devices such as base stations, they can send this information.

[0054] In specific implementation, the unit of the mode period value can be ms or slot. In the solution provided by the embodiments of the present invention, ms is mainly used as an example, but obviously it can also be used in the case where the unit is slot, and in this case, only a unit conversion is required for the value.

[0055] In specific implementation, for example, the methods for obtaining SL-TDD-Config include at least one of the following:

[0056] i. The communication device obtains it through configuration: In this method, the base station can directly configure SL-TDD-Config to the terminal through SL SIB or RRC.

[0057] ii. The communication device obtains it through pre-configuration: For example, SL-TDD-Config is directly pre-configured to the terminal in the pre-configuration.

[0058] iii. The communication device determines it by itself: For example, the terminal infers the SL-TDD-Config by itself according to the TDD configuration information obtained from the base station configuration, pre-configuration or PC5-RRC, such as TDD-UL-DL-ConfigCommon.

[0059] iv. The communication device is indicated by other devices: For example, it can be obtained from the received SL information, such as obtained from SL MIB or PC5-RRC. For example, UE2 receives the SL MIB of UE1, and the SL MIB carries SL-TDD-Config.

[0060] In the embodiments, when 1 or 2 TDD patterns are obtained, it may be that the SL-TDD-Config obtained (the meaning of "obtained" is as described above: configuration, pre-configuration, the terminal determines by itself, indicated by other terminals) indicates 1 or 2 TDD patterns, or it may be that the obtained TDD configuration information indicates 1 or 2 TDD patterns.

[0061] By adopting the embodiments of the present invention, it is possible to determine how to set the indication content of SL-TDD-Config according to the obtained TDD configuration information; and / or, if SL-TDD-Config is obtained, it is possible to determine how to understand the meaning indicated in SL-TDD-Config.

[0062] 1. The relationship between the first information and the second information.

[0063] In implementation, the first information indicates the number of patterns and the pattern period configuration in a manner of joint coding or independent coding.

[0064] In implementation, the second information indicates the available resources in a manner of joint coding indication or segmented indication.

[0065] In specific implementation, the two manners of the first information can be respectively used in combination with the two manners of the second information. For example, the first information adopts joint coding, and the second information uses joint coding indication or segmented indication; or, the first information adopts independent coding, and the second information uses joint coding indication or segmented indication.

[0066] In the embodiments provided in the embodiments of the present invention, free combination is also possible among the various embodiments. The main combinations are as follows:

[0067] 1), free combination of precisions under different SCSs;

[0068] 2), free combination of the first information coding manner and the second information indication manner.

[0069] 2. Implementation of the first information.

[0070] In specific implementation, when the first information indicates the number of patterns and the pattern period configuration in a manner of independent coding, it may include at least one of the following situations:

[0071] If the first bit corresponding to the number of patterns in the first information is within a first value range, the second bit corresponding to the pattern period configuration in the first information indicates two pattern period configurations, or indicates one pattern period configuration;

[0072] If the first bit corresponding to the number of patterns in the first information is within a second value range, the second bit corresponding to the pattern period configuration in the first information indicates two pattern period configurations.

[0073] In specific implementation, when the first information indicates the number of patterns and the pattern period configuration, it may be that one or more first information values correspond to the same pattern period configuration.

[0074] 3. Implementation of the second information.

[0075] For the case where there are two pattern periods P1 and P2, the first pattern period P1 and the second pattern period P2 may be the same or different, and examples will also be given in the following instances. For example, instances when P1 = 1 ms and P2 = 4 ms, and instances when P1 = 10 ms and P2 = 10 ms.

[0076] 1), implementation of segmented indication.

[0077] In implementation, when the second information indicates available resources, if there is one mode period and the mode period is configured as P, when the value indicated by the second information is n, it indicates that there are n available resources within the mode period P; or, when the value indicated by the second information is n, it indicates that there are n + A available resources within the mode period P.

[0078] In implementation, when the second information indicates available resources by segmented indication, if there are two mode periods and the mode periods are the first mode period P1 and the second mode period P2, the first resource information is used to indicate the available resources existing within the first mode period, and / or the second resource information is used to indicate the available resources existing within the second mode period.

[0079] In specific implementation, when the value indicated by the first resource information is n1, it indicates that there are n1 available resources within the first mode period; or, when the value indicated is n1, there are n1 + B available resources within the first mode period P1;

[0080] and / or,

[0081] when the value indicated by the second resource information is n2, it indicates that there are n2 available resources within the second mode period; or, when the value indicated is n2, there are n2 + C available resources within the second mode period P2.

[0082] A, B, and C are positive integers, and a possible value is 1.

[0083] 2) Implementation of joint coding indication.

[0084] In implementation, when the second information indicates available resources by joint coding, if there are two mode periods and the mode periods are the first mode period P1 and the second mode period P2, then:

[0085] when the value n indicated by the second information is within the first range, it indicates that there is a first quantity of available resources within the first mode period; or,

[0086] when the value n indicated by the second information is within the second range, it indicates that there is a second quantity of available resources within the second mode period; or,

[0087] when the value n indicated by the second information is within the third range, it indicates that there is a third quantity of available resources within the first mode period and a fourth quantity of available resources within the second mode period.

[0088] In specific implementation, the first quantity is determined according to the value of n, and / or the second quantity is determined according to the value of n and the first mode period P1.

[0089] When using the first information and the second information for indication, the adoption of the following four schemes is related to at least one of the following:

[0090] 1), SCS; 2), the value of the first information; 3), the number of patterns; 4), pattern period configuration.

[0091] 1. The second information uses the value n to indicate the number of available resource patterns and the pattern period, where:

[0092] If there is one pattern period and the period is P, SCS = 2 μ *15kHz:

[0093] When the indicated value is n, there are n available resources within the period P, and the range of n is 0 to min(2 Z -1, P * 2 μ ); or,

[0094] When the indicated value is n, there are n + 1 available resources within the period P, and the range of n is 1 to min(2 Z , P * 2 μ );

[0095] Where: μ takes values of: 0, 1, 2, or 3, and Z takes values of: the number of bits used by the second information.

[0096] 2. The first information uses a joint coding method to indicate the number of patterns and the pattern period by the value n, where:

[0097] If there are two pattern periods, the first pattern period is P1 and the second pattern period is P2, SCS = 2 μ *15kHz:

[0098] When the indicated value is n1, there are n1 available resources within the first pattern period P1, and the range of n1 is 0 to min(2 Z -1, P * 2 μ ); or,

[0099] When the indicated value is n1, there are n1 + 1 available resources within the period P, and the range of n1 is 1 to min(2 Z , P * 2 μ );

[0100] Where: μ takes values of: 0, 1, 2, or 3, and Z takes values of: the number of bits used in the second information to indicate n1;

[0101] And / or,

[0102] When the indicated value is n2, there are n2 available resources within the first pattern period P1, and the range of n2 is 0 to min(2 Z -1, P * 2 μ ); or,

[0103] When the indicated value is n2, there are n2 + 1 available resources within the first mode period P, where n2 ranges from 1 to min(2 Z , P * 2 μ );

[0104] Where: μ takes values of: 0, 1, 2, or 3, and Z takes values of: the number of bits used in the second information to indicate the use of n2.

[0105] 3. The second information uses joint coding to indicate the number of modes and the mode period by the value n, where:

[0106] If there are two mode periods, the mode periods are the first mode period P1 and the second mode period P2, and SCS = 2 μ * 15 kHz, then there are:

[0107] When the indicated value is n, if n ranges from 0 to P1 * 2 μ , there are n or n + 1 available resources in mode 1; or,

[0108] When the indicated value is n, if n ranges from P1 * 2 μ + 1 to P1 * 2 μ + P2 * 2 μ + 1, there are n - P1 * 2 μ - 1 or n - P1 * 2 μ available resources in mode 2; or,

[0109] When the indicated value is n, if n ranges from P1 * 2 μ + P2 * 2 μ + 2 to (P1 * 2 μ + 1) * (P2 * 2 μ + 1):

[0110] There are available resources in mode 1, and there are (n - P1 * 2 μ - P2 * 2 μ - 1) mod L available resources in mode 2, or,

[0111] There are (n - P1 * 2 μ - P2 * 2 μ - 1) mod L available resources in mode 1, and there are available resources in mode 2, or,

[0112] Where L is a positive integer, and a possible value is 64.

[0113] Where: μ takes values of: 0, 1, 2, or 3, and Z takes values of: the number of bits used in the second information.

[0114] 4. If there are two pattern periods, and the pattern periods are the first pattern period P1 and the second pattern period P2 respectively, and the subcarrier spacing = 2 μ *15 kHz, then there is:

[0115] The value indicated by the second information is n. Let R = (n + 1) mod L. Then there are S available resources in the first pattern period and R available resources in the second pattern period; or,

[0116] The value indicated by the second information is n. Let R = (n + 1) mod L. Then there are S + A1 available resources in the first pattern period and R + A2 available resources in the second pattern period;

[0117] Or,

[0118] The value indicated by the second information is n. Let R = (n + 1) mod L. Then there are R available resources in the first pattern period and S available resources in the second pattern period; or,

[0119] The value indicated by the second information is n. Let R = (n + 1) mod L. Then there are R + A3 available resources in the first pattern period and S + A4 available resources in the second pattern period;

[0120] Wherein, L is a positive integer. For example, it can be 64. is the floor function. A1, A2, A3, and A4 are positive integers, and a possible value is 1.

[0121] The indication accuracy of the second information is related to at least one of the following:

[0122] 1), SCS;

[0123] 2), the value of the first information;

[0124] 3), the number of patterns;

[0125] 4), the pattern period configuration.

[0126] The following gives an overall description of the example technical means used in the example part, such as the number of bits.

[0127] In the embodiments of the present invention, assume at least one of the following:

[0128] 1. When SCS = 30k, the number of available resources in each pattern period is less than or equal to 16;

[0129] 2. When SCS = 60k, the number of available resources in each pattern period is less than or equal to 32;

[0130] 3. When SCS = 120k, the number of available resources within each pattern period is less than or equal to 64.

[0131] In the example, the first information and the second information in the indication information will be indicated according to the following number of bits:

[0132] When using 5 bits for the first information to indicate the number of patterns and the pattern period configuration, and using 8 bits for the second information to indicate the available resources; or,

[0133] When using 5 bits for the first information to indicate the number of patterns and the pattern period configuration, and using 7 bits for the second information to indicate the available resources; or,

[0134] When using 1 bit for the first information to indicate the number of patterns and 4 bits to indicate the pattern period configuration, and using 8 bits for the second information to indicate the available resources; or,

[0135] When using 1 bit for the first information to indicate the number of patterns and 4 bits to indicate the pattern period configuration, and using 7 bits for the second information to indicate the available resources.

[0136] In the example, it is assumed that SL-TDD-Config uses a total of T bits;

[0137] In the following solutions, Z = 8 bits will be taken as an example for illustration. It can be either a 4-bit + 4-bit segmented indication or an 8-bit combined indication. Similarly for Z = 7 bits, that is, even if there is only a description of the combined indication in a certain solution, in fact, the segmented indication can also be selected.

[0138] For the case of segmented indication, it can be understood that Z = Z1 + Z2, and there can be multiple permutations and combinations of Z1 and Z2. Taking Z = 8 bits as an example, 4-bit + 4-bit or 3-bit + 5-bit or 5-bit + 3-bit or 2-bit + 6-bit or 6-bit + 2-bit or 1-bit + 7-bit or 7-bit + 1-bit can all implement the solutions in the embodiments of the present invention. In specific examples, 4-bit + 4-bit or 4-bit + 3-bit will be mainly taken as examples for illustration.

[0139] It should also be noted that in the above examples, T = 12 and T = 13 are taken as examples for illustration. However, it is easy to understand that based on the indication of the number of bits, the more bits there are, the more information can be carried, and more accurate indication can be achieved. Therefore, for example, when T = 14, with an increase of 1 bit, more accurate indication can be achieved. However, it can be foreseen that if the number of bits is sufficient, according to the technical solutions provided in the embodiments of the present invention, resources can be constantly allocated with a precision of 1 slot under all SCS or cycle configurations.

[0140] In addition, although the number of bits is different, the joint coding indication and segmentation indication of the second information are technical means that can always be adopted. For example, when T = 14, Z = 9 bits, and these 9 bits can also be arranged and combined and split.

[0141] The following will be specifically described in four ways.

[0142] Method 1: Implementation when using 5 bits in the first information to indicate the number of patterns and the pattern period configuration, and using 8 bits in the second information to indicate the available resources.

[0143] In this method, the second information occupies Z = 8 bits, and the first information adopts the joint coding method, and the resource indication accuracy is not greater than 2 slots.

[0144] For example, the number of patterns and the pattern period configuration are jointly coded. The first information indicates the number of patterns and the pattern period configuration. The first information can be X + Y = 5 bits, with values from 0 to 31. The second information occupies Z = 8 bits to indicate the available resources, that is, T = Z + X + Y = 13 bits. Among them:

[0145] The second information indicating the resources indicates the number of available resources;

[0146] Furthermore, the available resources can be uplink resources and / or resources that meet at least the preset requirements;

[0147] Furthermore, the above-mentioned preset requirement means that the resources from symbol S to symbol S + L - 1 are uplink resources;

[0148] For example, S = 2, L = 7. If the resources from symbol 3 to symbol 11 in a slot are uplink resources, then this slot does not meet the requirements; if the resources from symbol 2 to symbol 9 in a slot are uplink resources, then this slot meets the requirements.

[0149] Optionally, at this time, the indication accuracy of the resource information is not greater than 2 slots.

[0150] It can be understood that the meaning of the indicated content is related to the SCS for transmitting sidelink.

[0151] 1. If 1 TDD pattern is configured and the period of the TDD pattern is P, the value of the first information is from 0 to 8, and each value corresponds to a period configuration for 1 pattern. Among them, when the SCS is 15k, 30k, 60k, or 120k, the second information indicates the available resources within the period P.

[0152] Specifically, when (pre-configured) 1 TDD pattern is configured, the period of the TDD pattern is P;

[0153] Optionally, the first information takes values from 0 to 8, and each value corresponds to a period configuration for 1 pattern.

[0154] For example, when the code point takes the value 8, it corresponds to the configuration with a period of 10 ms for 1 pattern.

[0155] Optionally, the meaning of the resource information can be specifically as follows:

[0156] (1) SCS = 15k:

[0157] The resource information Z = 8 bits indicates the available resources within the period P, and its indication accuracy is 1 slot.

[0158] For example, when SCS = 15k and the period configuration is 10 ms, there are 10 slots in total within the period, and there are 11 kinds of available resources in total. The 8-bit indication corresponds to 0 - 10 among 256 code points. For example, code point 10 indicates that the available resource is 10 slots.

[0159] (2) SCS = 30k:

[0160] The resource information Z = 8 bits indicates the available resources within the period P, and its indication accuracy is 1 slot.

[0161] (3) SCS = 60k:

[0162] The resource information Z = 8 bits indicates the available resources within the period P, and its indication accuracy is 1 slot.

[0163] (4) SCS = 120k:

[0164] The resource information Z = 8 bits indicates the available resources within the period P, and its indication accuracy is 1 slot.

[0165] 2. If 2 TDD patterns are configured, the periods of the TDD patterns are P1 and P2, and when P1 + P2 ≤ 5 ms, the first information takes values from 9 to 22, and each value corresponds to a period configuration for 2 patterns. Among them: when SCS is 15k, 30k, or 60k, the second information indicates the available resources of P1 and P2, or 4 bits are used in the second information to indicate the available resources of P1, and 4 bits are used to indicate the available resources of P2.

[0166] Specifically, when (pre-configured) 2 TDD patterns are configured, the periods of the two TDD patterns are P1 and P2 respectively, and when P1 + P2 ≤ 5 ms:

[0167] Optionally, the first information takes values from 9 to 22, and each value corresponds to a periodic configuration for 2 patterns.

[0168] For example, when the code point takes the value 22 and corresponds to configuring 2 patterns, P1 = 1 ms and P2 = 4 ms.

[0169] Optionally, the meaning of the resource information can be specifically as follows:

[0170] (1) SCS = 15k:

[0171] The high 4 bits of the 8-bit resource information Z are used to indicate the available resources of P1, and the low 4 bits are used to indicate the available resources of P2. The indication accuracy is 1 slot for both.

[0172] For example, when SCS = 15k and the periodic configuration is P1 = 10 ms and P2 = 10 ms, then there are 10 slots in each period, and there are a total of 11 kinds of available resources in each period. At this time, the high 4 bits indicate 16 code points (0 - 15), and let the code points 0 - 10 represent the available resources in P1. The low 4 bits indicate 16 code points (0 - 15), and let the code points 0 - 10 represent the available resources in P2. For example, the code point 10 indicated by the high 4 bits means that the available resource in P1 is 10 slots, and the code point 10 indicated by the low 4 bits means that the available resource in P2 is 10 slots.

[0173] Alternatively, the 8-bit combined coding indicates the available resources of P1 + P2, and its indication accuracy is 1 slot.

[0174] For example, when SCS = 15k and the periodic configuration is P1 = 10 ms and P2 = 10 ms, then there are 10 slots in each period, and there are a total of 11 * 11 = 121 kinds of available resources, corresponding to 0 - 120 among the 256 code points indicated by 8 bits. For example, the code point 120 means that the available resource in P1 is 10 slots and the available resource in P2 is 10 slots.

[0175] (2) SCS = 30k:

[0176] The high 4 bits of the 8-bit resource information Z are used to indicate the available resources of P1, and the low 4 bits are used to indicate the available resources of P2. The indication accuracy is 1 slot for both.

[0177] Alternatively, the 8-bit combined coding indicates the available resources of P1 + P2, and its indication accuracy is 1 slot.

[0178] (3) SCS = 60k:

[0179] The upper 4 bits of the 8-bit resource information Z are used to indicate the available resources of P1, and the lower 4 bits are used to indicate the available resources of P2, with an indication accuracy of 1 slot for both.

[0180] Alternatively, 8-bit joint coding indicates the available resources of P1 + P2, with an indication accuracy of 1 slot.

[0181] (4) SCS = 120k:

[0182] 1) If 2 TDD patterns are configured, the periods of the TDD patterns are P1 and P2, and when P1 + P2 ≤ 2.5 ms, the first information takes values from 9 to 14, and each value corresponds to a period configuration for 2 patterns. Among them: when SCS is 120k, the second information indicates the available resources of P1 and P2, or 4 bits are used in the second information to indicate the available resources of P1, and 4 bits are used to indicate the available resources of P2.

[0183] Specifically, when P1 + P2 ≤ 2.5 ms, the first information takes values from 9 to 14.

[0184] The upper 4 bits of the 8-bit resource information Z are used to indicate the available resources of P1, and the lower 4 bits are used to indicate the available resources of P2, with an indication accuracy of 1 slot for both.

[0185] Alternatively, 8-bit joint coding indicates the available resources of P1 + P2, with an indication accuracy of 1 slot.

[0186] 2) If 2 TDD patterns are configured, the periods of the TDD patterns are P1 and P2, P1 = 2 ms, P2 = 2 ms, and when 2.5 ms ≤ P1 + P2 ≤ 5 ms, the first information takes the value of 15, and each value corresponds to a period configuration for 2 patterns. Among them: when SCS is 120k, the second information indicates the available resources of P1 and P2, or 4 bits are used in the second information to indicate the available resources of P1, and 4 bits are used to indicate the available resources of P2.

[0187] When 2.5 ms < P1 + P2 ≤ 5 ms:

[0188] P1 = 2 ms, P2 = 2 ms, and the first information takes the value of 15.

[0189] The upper 4 bits of the 8-bit resource information Z are used to indicate the available resources of P1, and the lower 4 bits are used to indicate the available resources of P2, with an indication accuracy of 1 slot for both.

[0190] Alternatively, 8-bit joint coding indicates the available resources of P1 + P2, with an indication accuracy of 1 slot.

[0191] 3. If 2 TDD patterns are configured, the pattern periods of the TDD patterns are the first pattern period P1 and the second pattern period P2, and when 2.5 ms ≤ P1 + P2 ≤ 5 ms, the first information takes values from 16 to 22, and each value corresponds to a cycle configuration for one of the 2 patterns. Among them: when SCS is 120k, the second information indicates the available resources of the first pattern period P1 and the second pattern period P2.

[0192] Specifically, the first information takes values from 16 to 22.

[0193] Let the available resource indication accuracy of any one of P1 or P2 be 2 slots, and the other be 1 slot, then the resource information Z = 8 bits is jointly encoded to indicate the available resources of P1 + P2.

[0194] When (pre - configured) 2 TDD patterns are configured, the pattern periods of the two TDD patterns are the first pattern period P1 and the second pattern period P2 respectively, and when P1 + P2 ≥ 10 ms:

[0195] Optionally, the first information takes values from 23 to 31, and each value or multiple values correspond to a cycle configuration for 2 patterns.

[0196] For example, when SCS = 120k, the code point values from 26 to 30 all correspond to the configuration of 2 patterns, where P1 = 10 ms and P2 = 10 ms.

[0197] The meaning of the resource information is as follows:

[0198] (1) SCS = 15k:

[0199] If 2 TDD patterns are configured, the pattern periods of the TDD patterns are the first pattern period P1 and the second pattern period P2, and when 10 ms ≤ P1 + P2, the first information takes values from 23 to 31, and each value or multiple values correspond to a cycle configuration for 2 patterns. Among them: when SCS is 15k, the second information indicates the available resources of the first pattern period P1 and the second pattern period P2, or 4 bits are used in the second information to indicate the available resources of P1, and 4 bits are used to indicate the available resources of P2.

[0200] Specifically, the high 4 bits of the 8 - bit resource information Z are used to indicate the available resources of P1, and the low 4 bits are used to indicate the available resources of P2, and the indication accuracy is 1 slot for both.

[0201] Or, 8 bits are jointly encoded to indicate the available resources of P1 + P2, and its indication accuracy is 1 slot.

[0202] (2) SCS = 30k:

[0203] 1) If 2 TDD patterns are configured, the pattern periods of the TDD patterns are the first pattern period P1 and the second pattern period P2, P1 = 5 ms, P2 = 5 ms, and when 10 ms ≤ P1 + P2, the first information takes the value of 23. Each value or multi - value corresponds to a cycle configuration of 2 patterns. Among them, when SCS is 30k, the second information indicates the available resources of the first pattern period P1 and the second pattern period P2, or, in the second information, 4 bits are used to indicate the available resources of P1, and 4 bits are used to indicate the available resources of P2.

[0204] Specifically, P1 = 5 ms, P2 = 5 ms, and the first information takes the value of 23.

[0205] The high 4 bits of the 8 - bit resource information Z are used to indicate the available resources of P1, and the low 4 bits are used to indicate the available resources of P2, and the indication accuracy is 1 slot for both.

[0206] Or, 8 - bit joint coding indicates the available resources of P1 + P2, and its indication accuracy is 1 slot.

[0207] 2) If 2 TDD patterns are configured, the pattern periods of the TDD patterns are the first pattern period P1 and the second pattern period P2, P1 = 10 ms, P2 = 10 ms, and when 10 ms ≤ P1 + P2, the first information takes the value of 24. Each value or multi - value corresponds to a cycle configuration of 2 patterns. Among them, when SCS is 30k, the second information indicates the available resources of the first pattern period P1 and the second pattern period P2.

[0208] Specifically, P1 = 10 ms, P2 = 10 ms, and the first information takes the value of 24.

[0209] Let the indication accuracy of the available resources of any one of P1 or P2 be 2 slots, and the other be 1 slot, then the 8 - bit resource information Z is used for joint coding to indicate the available resources of P1 + P2, or,

[0210] The resource indication accuracies of both P1 and P2 are 1 slot, or,

[0211] The resource indication accuracies of both P1 and P2 are 2 slots.

[0212] (3) SCS = 60k:

[0213] If 2 TDD patterns are configured, the pattern periods of the TDD patterns are the first pattern period P1 and the second pattern period P2, P1 = 5 ms, P2 = 5 ms, and when 10 ms ≤ P1 + P2, the first information takes the value of 23. Each value or multi-value corresponds to a cycle configuration for 2 patterns. Among them, when SCS is 60k, the second information indicates the available resources of P1 and P2.

[0214] Specifically, P1 = 5 ms, P2 = 5 ms, and the first information takes the value of 23.

[0215] Let the available resource indication accuracy of any one of P1 or P2 be 2 slots, and the other be 1 slot. Then, the resource information Z = 8 bits is used for joint coding to indicate the available resources of P1 + P2, or

[0216] the available resource indication accuracies of P1 and P2 are both 1 slot, or

[0217] the available resource indication accuracies of P1 and P2 are both 2 slots.

[0218] If 2 TDD patterns are configured, the pattern periods of the TDD patterns are P1 and P2, P1 = 10 ms, P2 = 10 ms, and when 10 ms ≤ P1 + P2, the first information takes the values of 24 - 25. Each value or multi-value corresponds to a cycle configuration for 2 patterns. Among them, when SCS is 60k, the second information indicates the available resources of P1 and P2.

[0219] P1 = 10 ms, P2 = 10 ms, and the first information takes the values of 24 - 25.

[0220] Let the available resource indication accuracies of P1 and P2 be both 2 slots. Then, the resource information Z = 8 bits is used for joint coding to indicate the available resources of P1 + P2. At this time, one cycle configuration corresponds to two code points.

[0221] (4) SCS = 120k:

[0222] 1) If 2 TDD patterns are configured, the periods of the TDD patterns are P1 and P2, P1 = 5 ms, P2 = 5 ms, and when 10 ms ≤ P1 + P2, the first information takes the values of 23 - 25. Each value or multi-value corresponds to a cycle configuration for 2 patterns. Among them, when SCS is 120k, the second information indicates the available resources of P1 and P2.

[0223] Specifically, P1 = 5 ms, P2 = 5 ms, and the first information takes the values of 23 - 25.

[0224] In specific implementation, if 2 TDD patterns are configured, the periods of the TDD patterns are P1 and P2, P1 = 5 ms, P2 = 5 ms, and when 10 ms ≤ P1 + P2, the first information takes values from 23 to 25, and each value or multi-value corresponds to a period configuration for 2 patterns, where: when SCS is 120k, the second information indicates among the available resources of P1 and P2:

[0225] Only one of P1 and P2 has available resources, and the first information takes the value of 23; both P1 and P2 have available resources, and the first information takes values from 24 to 25.

[0226] Specifically, only one of P1 and P2 has available resources, and the first information takes the value of 23.

[0227] The resource information Z = 8-bit jointly encodes to indicate the available resources, and its indication accuracy is 1 slot, or its indication accuracy is 2 slots.

[0228] For example, when SCS = 120k and the period configuration is P1 = 5 ms, P2 = 5 ms, then there are a total of 40 slots in only 1 period, and the available resources are a total of 41 + 41 - 1 = 81 types (subtracting the case where both periods are 0 slots that are repeated), corresponding to 0 - 81 among the 256 code points indicated by 8 bits. For example, code point 40 indicates that the available resources in P1 are 40 slots and the available resources in P2 are 0 slots; code point 81 indicates that the available resources in P2 are 41 slots and the available resources in P1 are 0 slots.

[0229] Both P1 and P2 have available resources, and the first information takes values from 24 to 25.

[0230] Let the indication accuracy of the available resources of P1 and P2 be both 2 slots, then the resource information Z = 8-bit jointly encodes to indicate the available resources of P1 + P2, and at this time, one period configuration corresponds to two code points.

[0231] 2) If 2 TDD patterns are configured, the periods of the TDD patterns are P1 and P2, P1 = 10 ms, P2 = 10 ms, and when 10 ms ≤ P1 + P2, the first information takes values from 26 to 30, and each value or multi-value corresponds to a period configuration for 2 patterns, where: when SCS is 120k, the second information indicates the available resources of P1 and P2.

[0232] For example, when SCS = 120k, the cycle configuration is P1 = 5ms and P2 = 5ms, there are 40 slots in each cycle, and the indication accuracy is 2 slots. Then there are a total of 21 * 21 - 1 = 440 available resources. When the first value is 24, it corresponds to 0 - 219 among the 256 code points indicated by 8 bits, and when the first value is 25, it corresponds to 0 - 219 among the 256 code points indicated by 8 bits. For example, when the first value is 25, code point 219 indicates that there are 40 slots of available resources in P1 and 40 slots of available resources in P2.

[0233] Specifically, when P1 = 10ms and P2 = 10ms, assuming that the number of available resources in P1 and P2 respectively ≤ 64, the first information value is 26 - 30.

[0234] If 2 TDD patterns are configured, the periods of the TDD patterns are P1 and P2, P1 = 10ms, P2 = 10ms, and when 10ms ≤ P1 + P2, the first information value is 26 - 30. Each value or multiple values correspond to a cycle configuration for 2 patterns. Among them, when SCS is 120k, the second information indicates the available resources in P1 and P2:

[0235] Only one of P1 and P2 has available resources, and the first information value is 26; both P1 and P2 have available resources, and the first information value is 27 - 30.

[0236] Specifically, assuming that only one of P1 and P2 has available resources, the first information value is 26.

[0237] The resource information Z is jointly encoded by 8 bits to indicate the available resources, and its indication accuracy is 1 slot, or its indication accuracy is 2 slots.

[0238] It can be understood that when both P1 and P2 have available resources, the first information value is 27 - 30.

[0239] For example, if the indication accuracy of the available resources of P1 and P2 is both 2 slots, then the resource information Z = 8 bits is used for joint encoding to indicate the available resources of P1 + P2. At this time, one cycle configuration corresponds to four code points.

[0240] Method 2: Implementation when the first information uses 5 bits to indicate the number of patterns and the pattern cycle configuration, and the second information uses 7 bits to indicate the available resources.

[0241] In this method, the second information occupies Z = 7 bits, and the first information uses a joint encoding method. The resource indication accuracy is not greater than 4 slots. Its feature is that it reduces the overhead by 1 bit compared to Method 1.

[0242] Specifically, the number of patterns and the pattern period configuration are jointly encoded. The first piece of information indicates the number of patterns and the pattern period configuration. The first piece of information is X + Y = 5 bits, with values ranging from 0 to 31. The second piece of information occupies Z = 7 bits and is used to indicate the available resources, that is, T = Z + X + Y = 12 bits. Among them:

[0243] The second piece of information indicating the resources indicates the number of available resources.

[0244] Furthermore, the available resources can be uplink resources and / or resources that meet at least a preset requirement.

[0245] Furthermore, the above-mentioned preset requirement means that the resources from symbol S to symbol S + L - 1 are uplink resources.

[0246] For example, when S = 2 and L = 7, if the resources of symbols 3 - 11 in a slot are uplink resources, then this slot does not meet the requirement; if the resources of symbols 2 - 9 in a slot are uplink resources, then this slot meets the requirement.

[0247] Optionally, the indication accuracy of the resource information is not greater than 4 slots at this time.

[0248] The meaning of the indicated content is related to the SCS for transmitting the SL MIB.

[0249] 1. If 1 TDD pattern is configured and the period of the TDD pattern is P, the first piece of information takes values from 0 to 8, and each value corresponds to a period configuration for 1 pattern. Among them: when the SCS is 15k, 30k, 60k, or 120k, the second piece of information indicates the available resources within the period P.

[0250] Specifically, when (pre - configured) 1 TDD pattern is configured, the period of the TDD pattern is P.

[0251] Optionally, the first piece of information takes values from 0 to 8, and each value corresponds to a period configuration for 1 pattern.

[0252] Optionally, the meaning of the resource information is as follows:

[0253] (1) SCS = 15k:

[0254] The resource information Z = 7 bits indicates the available resources within the period P, and its indication accuracy is 1 slot.

[0255] (2) SCS = 30k:

[0256] The resource information Z = 7 bits indicates the available resources within the period P, and its indication accuracy is 1 slot.

[0257] (3) SCS = 60k:

[0258] The resource information Z indicates the available resources within the indication period P, with an indication accuracy of 1 slot.

[0259] (4) SCS = 120k:

[0260] The resource information Z indicates the available resources within the indication period P, with an indication accuracy of 1 slot.

[0261] 2. If 2 TDD patterns are configured, the periods of the TDD patterns are P1 and P2, and when P1 + P2 ≤ 5 ms, the first information takes values from 9 to 22, and each value corresponds to a period configuration for 2 patterns. Among them: when SCS is 15k or 30k, the second information indicates the available resources of P1 and P2, or 4 bits are used in the second information to indicate the available resources of P1, and 3 bits are used to indicate the available resources of P2.

[0262] Specifically, when (pre - configured) 2 TDD patterns are configured, the periods of the two TDD patterns are P1 and P2 respectively, and when P1 + P2 ≤ 5 ms:

[0263] Optionally, the first information takes values from 9 to 22, and each value corresponds to a period configuration for 2 patterns.

[0264] Optionally, the meaning of the resource information is as follows:

[0265] (1) SCS = 15k:

[0266] The high 4 bits of the 7 - bit resource information Z are used to indicate the available resources of P1, and the low 3 bits are used to indicate the available resources of P2, with an indication accuracy of 1 slot for both.

[0267] Or, the 7 - bit combined coding indicates the available resources of P1 + P2, with an indication accuracy of 1 slot.

[0268] (2) SCS = 30k:

[0269] The high 4 bits of the 7 - bit resource information Z are used to indicate the available resources of P1, and the low 3 bits are used to indicate the available resources of P2, with an indication accuracy of 1 slot for both.

[0270] Or, the 7 - bit combined coding indicates the available resources of P1 + P2, with an indication accuracy of 1 slot.

[0271] (3) SCS = 60k:

[0272] If 2 TDD patterns are configured, with the periods of the TDD patterns being P1 and P2, and when P1 + P2 ≤ 5 ms, the first information takes values from 9 to 22, and each value corresponds to a period configuration for 2 patterns. Among them: when the SCS is 60k, the second information indicates the available resources of P1 and P2.

[0273] Specifically, the resource information Z = 7 bits is jointly encoded to indicate the available resources of P1 + P2, and its indication accuracy is 1 slot.

[0274] (4) SCS = 120k:

[0275] 1) If 2 TDD patterns are configured, with the periods of the TDD patterns being P1 and P2, and when P1 + P2 ≤ 4 ms, the first information takes values from 9 to 17, and each value corresponds to a period configuration for 2 patterns. Among them: when the SCS is 120k, the second information indicates the available resources of P1 and P2.

[0276] Specifically, when P1 + P2 ≤ 4 ms, the first information takes values from 9 to 17.

[0277] Let the indication accuracy of the available resources of any one of P1 or P2 be 2 slots, and the indication accuracy of the other be 1 slot, then the resource information Z = 7 bits is jointly encoded to indicate the available resources of P1 + P2.

[0278] 2) If 2 TDD patterns are configured, with the periods of the TDD patterns being P1 and P2, and when 4 ms ≤ P1 + P2 ≤ 5 ms, the first information takes values from 18 to 22, and each value corresponds to a period configuration for 2 patterns. Among them: when the SCS is 120k, the second information indicates the available resources of P1 and P2.

[0279] Specifically, when 4 ms < P1 + P2 ≤ 5 ms, the first information takes values from 18 to 22.

[0280] Let the indication accuracy of the available resources of both P1 and P2 be 2 slots, then the resource information Z = 7 bits is jointly encoded to indicate the available resources of P1 + P2.

[0281] 3. When (pre - configured) 2 TDD patterns are configured, with the periods of the two TDD patterns being P1 and P2 respectively, and when P1 + P2 ≥ 10 ms:

[0282] Optionally, the first information takes values from 23 to 31, and each value or multiple values correspond to a period configuration for 2 patterns.

[0283] Optionally, the meanings of the resource information are as follows:

[0284] (1) SCS = 15k:

[0285] 1) If 2 TDD patterns are configured, the periods of the TDD patterns are P1 and P2, P1 = 5ms, P2 = 5ms, and when 10ms ≤ P1 + P2, the first information takes the value of 23. Each value or multi - value corresponds to a period configuration of 2 patterns. Among them, when SCS is 15k, the second information indicates the available resources of P1 and P2, or 4 bits are used in the second information to indicate the available resources of P1, and 3 bits are used to indicate the available resources of P2.

[0286] Specifically, P1 = 5ms, P2 = 5ms, and the first information takes the value of 23.

[0287] For example, the high 4 bits in the 7 - bit resource information Z are used to indicate the available resources of P1, and the low 3 bits are used to indicate the available resources of P2, and the indication accuracy is 1 slot for both.

[0288] Or, the 7 - bit combined coding indicates the available resources of P1 + P2, and its indication accuracy is 1 slot.

[0289] 2) If 2 TDD patterns are configured, the periods of the TDD patterns are P1 and P2, P1 = 10ms, P2 = 10ms, and when 10ms ≤ P1 + P2, the first information takes the value of 24.

[0291] The resource information Z = 7 - bit combined coding indicates the available resources of P1 + P2, and its indication accuracy is 1 slot.

[0292] 4. If 2 TDD patterns are configured, the periods of the TDD patterns are P1 and P2, P1 = 5ms, P2 = 5ms, and when 10ms ≤ P1 + P2, the first information takes the value of 23. Each value or multi - value corresponds to a period configuration of 2 patterns. Among them, when SCS is 30k or 60k, the second information indicates the available resources of P1 and P2.

Each value or multi - value corresponds to a period configuration of 2 patterns. Among them, when SCS is 120k, the second information indicates the available resources of P1 and P2.

[0306] Specifically, P1 = 5 ms, P2 = 5 ms. Assuming the number of available resources in each of P1 and P2 ≤ 32, the first information takes values from 23 to 25.

[0307] If 2 TDD patterns are configured, the periods of the TDD patterns are P1 and P2, P1 = 5 ms, P2 = 5 ms, and when 10 ms ≤ P1 + P2, the first information takes values from 23 to 25, and each value or multi - value corresponds to a period configuration for 2 patterns, where: when SCS is 120k, the second information indicates among the available resources of P1 and P2:

[0308] Only one of P1 and P2 has available resources, the first information takes the value of 23; both P1 and P2 have available resources, the first information takes values from 24 to 25.

[0309] Specifically, only one of P1 and P2 has available resources, the first information takes the value of 23.

[0310] The resource information Z = 7 - bit joint coding indicates the available resources, and its indication accuracy is 1 slot.

[0311] Both P1 and P2 have available resources, the first information takes values from 24 to 25.

[0312] Let the indication accuracy of the available resources of P1 and P2 be both 2 slots, then the resource information Z = 7 - bit joint coding indicates the available resources of P1 + P2, and at this time one period configuration corresponds to two code points.

[0313] 2) If 2 TDD patterns are configured, the periods of the TDD patterns are P1 and P2, P1 = 10 ms, P2 = 10 ms, and when 10 ms ≤ P1 + P2, the first information takes values from 26 to 30, and each value or multi - value corresponds to a period configuration for 2 patterns, where: when SCS is 120k, the second information indicates the available resources of P1 and P2.

[0314] Specifically, P1 = 10 ms, P2 = 10 ms, assuming the number of available resources of each of P1 and P2 ≤ 64, the first information takes values from 26 to 30.

[0315] If 2 TDD patterns are configured, the periods of the TDD patterns are P1 and P2, P1 = 10 ms, P2 = 10 ms, and when 10 ms ≤ P1 + P2, the first information takes values from 26 to 30, and each value or multi - value corresponds to a period configuration for 2 patterns, where: when SCS is 120k, the second information indicates among the available resources of P1 and P2:

[0316] Only one of P1 and P2 has available resources, the first information takes the value of 26; both P1 and P2 have available resources, the first information takes values from 27 to 30.

[0317] Specifically, assume that only one of P1 and P2 has available resources, and the first information takes the value of 26.

[0318] For example, the resource information Z = 7 bits is jointly encoded to indicate available resources, and its indication accuracy is 1 slot.

[0319] Both P1 and P2 have available resources, and the first information takes values from 27 to 30.

[0320] Let the available resource indication accuracy of any one of P1 or P2 be 2 slots, and that of the other be 4 slots. Then, the resource information Z = 7 bits is jointly encoded to indicate the available resources of P1 + P2. At this time, one cycle configuration corresponds to four code points.

[0321] Method 3: Implementation when 1 bit of the first information indicates the number of patterns and 4 bits indicate the pattern cycle configuration, and 8 bits of the second information indicate available resources.

[0322] In this method, the second information occupies Z = 8 bits, and the first information adopts a joint encoding method. The resource indication accuracy is not greater than 2 slots, and its characteristic is that the accuracy is 2 slots. In the specific implementation, when configuring 2 patterns, the code points used when configuring 1 pattern need to be borrowed.

[0323] Specifically, the number of patterns and the pattern cycle configuration are independently encoded. X = 1 bit indicates the number of configured TDD patterns. The third information is the information indicating the pattern cycle configuration in the first information when configuring 1 TDD pattern, and the fourth information is the information indicating the pattern cycle configuration in the first information when configuring 2 TDD patterns. Then: when configuring 1 TDD pattern, the third information indicates the pattern cycle configuration, and the third information is Y = 4 bits, taking values from 0 to 15; when configuring 2 TDD patterns, the fourth information indicates the pattern cycle configuration, and the fourth information is Y = 4 bits, taking values from 0 to 15. Z = 8 bits is used to indicate available resources, that is, T = 13 bits. Among them:

[0324] The second information indicating resources indicates the number of available resources.

[0325] Furthermore, the available resources can be uplink resources and / or resources that meet at least a preset requirement.

[0326] Furthermore, the above-mentioned preset requirement means that the resources from symbol S to symbol S + L - 1 are uplink resources.

[0327] For example, when S = 2 and L = 7, if symbols 3 - 11 within a slot are uplink resources, then this slot does not meet the requirements; if symbols 2 - 9 within a slot are uplink resources, then this slot meets the requirements.

[0328] Optionally, the indication accuracy of the resource information is not greater than 2 slots at this time.

[0329] It can be understood that the meaning of the indicated content is related to the SCS for transmitting the SL MIB.

[0330] 1. If 1 TDD pattern is configured and the period of the TDD pattern is P, the value of the information indicating the pattern period configuration in the first information ranges from 0 - 15, and each value corresponds to a period configuration for 1 pattern. Among them: when the SCS is 15k, 30k, 60k, or 120k, the second information indicates the available resources within the period P.

[0331] Specifically, when (pre - configured) 1 TDD pattern is configured, the period of the TDD pattern is P.

[0332] Optionally, the value of the third information ranges from 0 - 15, and actually only 0 - 8 (a total of 9 single - periods) are used, and the remaining 9 - 15 are used for the case of configuring 2 TDD patterns.

[0347] For the resource information Z, the upper 4 bits of the 8 bits are used to indicate the available resources of P1, and the lower 4 bits are used to indicate the available resources of P2, with the indication accuracy being 1 slot for both.

[0348] Alternatively, the 8 bits are jointly encoded to indicate the available resources of P1 + P2, with the indication accuracy being 1 slot.

[0349] (2) SCS = 30k:

[0350] For the resource information Z, the upper 4 bits of the 8 bits are used to indicate the available resources of P1, and the lower 4 bits are used to indicate the available resources of P2, with the indication accuracy being 1 slot for both.

[0351] Alternatively, the 8 bits are jointly encoded to indicate the available resources of P1 + P2, with the indication accuracy being 1 slot.

[0352] (3) SCS = 60k:

[0353] For the resource information Z, the upper 4 bits of the 8 bits are used to indicate the available resources of P1, and the lower 4 bits are used to indicate the available resources of P2, with the indication accuracy being 1 slot for both.

[0354] Alternatively, the 8 bits are jointly encoded to indicate the available resources of P1 + P2, with the indication accuracy being 1 slot.

[0355] (4) SCS = 120k:

[0356] 1) If 2 TDD patterns are configured, with the periods of the TDD patterns being P1 and P2, and P1 + P2 ≤ 2.5 ms, the value of the information indicating the pattern period configuration in the first information ranges from 0 to 5, and each value corresponds to a period configuration for 2 patterns. Among them: when the SCS is 120k, the second information indicates the available resources of P1 and P2, or 4 bits are used in the second information to indicate the available resources of P1, and 4 bits are used to indicate the available resources of P2.

[0357] When P1 + P2 ≤ 2.5 ms, the value of the fourth information ranges from 0 to 5.

[0358] The high 4 bits of the 8-bit resource information Z are used to indicate the available resources of P1, and the low 4 bits are used to indicate the available resources of P2, with an indication accuracy of 1 slot for both.

[0359] Or, 8 bits are jointly encoded to indicate the available resources of P1 + P2, with an indication accuracy of 1 slot.

[0360] 2) If 2 TDD patterns are configured, with the periods of the TDD patterns being P1 and P2, P1 = 2 ms, P2 = 2 ms, and 2.5 ms ≤ P1 + P2 ≤ 5 ms, the value of the information indicating the pattern period configuration in the first information is 6, and each value corresponds to a period configuration for 2 patterns. Among them: when the SCS is 120k, the second information indicates the available resources of P1 and P2, or 4 bits are used in the second information to indicate the available resources of P1, and 4 bits are used to indicate the available resources of P2.

[0364] Or, 8 bits are jointly encoded to indicate the available resources of P1 + P2, with an indication accuracy of 1 slot.

[0365] 3. If 2 TDD patterns are configured, with the periods of the TDD patterns being P1 and P2, and 2.5 ms ≤ P1 + P2 ≤ 5 ms, the value of the information indicating the pattern period configuration in the first information ranges from 7 to 13, and each value corresponds to a period configuration for 2 patterns. Among them: when the SCS is 120k, the second information indicates the available resources of P1 and P2.

[0366] The fourth information value ranges from 7 to 13.

[0367] Let the available resource indication precision of any one of P1 or P2 be 2 slots, and the other be 1 slot. Then, the resource information Z = 8 bits is used for joint coding to indicate the available resources of P1 + P2.

[0368] When (pre-configured) 2 TDD patterns are configured, the periods of the two TDD patterns are P1 and P2 respectively, and P1 + P2 ≥ 10 ms:

[0369] Optionally, the fourth information value ranges from 14 to 15, and the third information value ranges from 9 to 15. Each value or multiple values correspond to a period configuration for 2 patterns.

[0370] Optionally, the meaning of the resource information is as follows:

[0386] 1) If 2 TDD patterns are configured, with the periods of the TDD patterns being P1 and P2, P1 = 5 ms, P2 = 5 ms, and when 10 ms ≤ P1 + P2, the value of the information indicating the pattern period configuration in the first information when configuring 1 TDD pattern is 14, and each value or multi - value corresponds to a period configuration for 2 patterns. Among them, when SCS is 60 k, the second information indicates the available resources of P1 and P2.

[0387] Specifically, P1 = 5 ms, P2 = 5 ms, and the value of the fourth information is 14.

[0388] Let the available resource indication accuracy of any one of P1 or P2 be 2 slots, and the other be 1 slot. Then, the resource information Z = 8 bits is used for joint coding to indicate the available resources of P1 + P2, or,

[0389] The resource indication accuracies of both P1 and P2 are 1 slot, or,

[0390] The resource indication accuracies of both P1 and P2 are 2 slots.

[0391] 2) If 2 TDD patterns are configured, with the periods of the TDD patterns being P1 and P2, P1 = 10 ms, P2 = 10 ms, and when 10 ms ≤ P1 + P2, the value of the information indicating the pattern period configuration in the first information when configuring 1 TDD pattern is 9, and the value of the information indicating the pattern period configuration in the first information when configuring 2 TDD patterns is 15.

[0393] Let the available resource indication accuracies of both P1 and P2 be 2 slots. Then, the resource information Z = 8 bits is used for joint coding to indicate the available resources of P1 + P2. At this time, one period configuration corresponds to two code points.

[0394] (4) SCS = 120 k:

[0395] 1) If 2 TDD patterns are configured, the periods of the TDD patterns are P1 and P2, P1 = 5 ms, P2 = 5 ms, and when 10 ms ≤ P1 + P2, the value of the information indicating the pattern period configuration in the first information when 1 TDD pattern is configured is 9, and the value of the information indicating the pattern period configuration in the first information when 2 TDD patterns are configured is 14 - 15. Each value or multiple values correspond to a period configuration for 2 patterns. Among them, when SCS is 120k, the second information indicates the available resources of P1 and P2.

[0396] Specifically, P1 = 5 ms, P2 = 5 ms, the value of the fourth information is 14 - 15, and the value of the third information is 9.

[0397] When 2 TDD patterns are configured, the periods of the TDD patterns are P1 and P2, P1 = 5 ms, P2 = 5 ms, and when 10 ms ≤ P1 + P2, the value of the information indicating the pattern period configuration in the first information when 1 TDD pattern is configured is 9, and the value of the information indicating the pattern period configuration in the first information when 2 TDD patterns are configured is 14 - 15. Each value or multiple values correspond to a period configuration for 2 patterns. Among them, when SCS is 120k, the second information indicates the available resources of P1 and P2:

[0398] Only one of P1 and P2 has available resources, the value of the information indicating the pattern period configuration in the first information when 2 TDD patterns are configured is 14; both P1 and P2 have available resources, the value of the information indicating the pattern period configuration in the first information when 1 TDD pattern is configured is 9, and the value of the information indicating the pattern period configuration in the first information when 2 TDD patterns are configured is 15.

[0399] Specifically, when only one of P1 and P2 has available resources, the value of the fourth information is 14.

[0400] For example, the resource information Z = 8 - bit joint coding indicates the available resources, and its indication accuracy is 1 slot, or its indication accuracy is 2 slots.

[0401] Both P1 and P2 have available resources, the value of the fourth information is 15, and the value of the third information is 9.

[0402] Let the indication accuracy of the available resources of P1 and P2 be both 2 slots, then the resource information Z = 8 - bit joint coding indicates the available resources of P1 + P2. At this time, one period configuration corresponds to two code points.

[0403] 2) If two TDD patterns are configured, with the periods of the TDD patterns being P1 and P2, P1 = 10 ms, P2 = 10 ms, and when 10 ms ≤ P1 + P2, the value of the information indicating the pattern period configuration in the first information when two TDD patterns are configured is the same as the value of the information indicating the pattern period configuration in the first information when one TDD pattern is configured, which is 10 - 14. Each value or multiple values correspond to a period configuration for two patterns. Among them, when the SCS is 120k, the second information indicates the available resources of P1 and P2.

[0404] Specifically, P1 = 10 ms, P2 = 10 ms. Assuming that the number of available resources in each of P1 and P2 ≤ 64, the value of the fourth information is the same as the value of the third information, which is 10 - 14.

[0405] Regarding the case where two TDD patterns are configured, with the periods of the TDD patterns being P1 and P2, P1 = 10 ms, P2 = 10 ms, and when 10 ms ≤ P1 + P2, the value of the information indicating the pattern period configuration in the first information when two TDD patterns are configured is the same as the value of the information indicating the pattern period configuration in the first information when one TDD pattern is configured, which is 10 - 14. Each value or multiple values correspond to a period configuration for two patterns. Among them, when the SCS is 120k, the second information indicates the available resources of P1 and P2:

[0406] If only one of P1 and P2 has available resources, the value of the information indicating the second pattern period P2 in the first information is 10; if both P1 and P2 have available resources, the value of the information indicating the pattern period configuration in the first information when two TDD patterns are configured is the same as the value of the information indicating the pattern period configuration in the first information when one TDD pattern is configured, which is 11 - 14.

[0407] Specifically, assuming that only one of P1 and P2 has available resources, the value of the fourth information is the same as the value of the third information, which is 10.

[0408] The resource information Z is jointly encoded with 8 bits to indicate the available resources, and its indication accuracy is 1 slot, or its indication accuracy is 2 slots.

[0409] If both P1 and P2 have available resources, the value of the fourth information is the same as the value of the third information, which is 11 - 14.

[0410] Let the available resource indication accuracy of both P1 and P2 be 2 slots. Then, the resource information Z = 8 bits is used for joint coding to indicate the available resources of P1 + P2. At this time, one cycle configuration corresponds to four code points.

[0411] Method 4: When using 1 bit in the first information to indicate the number of patterns and 4 bits to indicate the pattern cycle configuration, and using 7 bits in the second information to indicate the available resources.

[0412] In this method, the second information occupies Z = 7 bits, and the first information and the second information adopt an independent coding method. The resource indication accuracy is not greater than 4 slots. Its feature is that, compared with Solution 3, it reduces 1 bit of overhead. In the specific implementation, when configuring 2 patterns, the code points used when configuring 1 pattern need to be borrowed.

[0413] Specifically, the number of patterns and the pattern cycle configuration are independently coded. X = 1 bit indicates the number of configured TDD patterns. The third information is the information indicating the pattern cycle configuration in the first information when configuring 1 TDD pattern, and the fourth information is the information indicating the pattern cycle configuration in the first information when configuring 2 TDD patterns. Then: When configuring 1 TDD pattern, the third information indicates the pattern cycle configuration. The third information is Y = 4 bits, with values from 0 to 15; when configuring 2 TDD patterns, the fourth information indicates the pattern cycle configuration. The fourth information is Y = 4 bits, with values from 0 to 15. Z = 7 bits is used to indicate the available resources, that is, T = 12 bits. Among them:

[0414] The second information indicating the resources indicates the number of available resources.

[0415] Furthermore, the available resources can be uplink resources and / or resources that meet at least a preset requirement.

[0416] Furthermore, the preset requirement means that the resources from symbol S to symbol S + L - 1 are uplink resources.

[0417] For example, S = 2, L = 7. If the resources of symbols 3 - 11 in a slot are uplink resources, then this slot does not meet the requirement; if the resources of symbols 2 - 9 in a slot are uplink resources, then this slot meets the requirement.

[0418] Optionally, at this time, the indication accuracy of the resource information is not greater than 4 slots.

[0419] It can be understood that the meaning of the indicated content is related to the SCS for transmitting the SL MIB.

[0420] 1. If one TDD pattern is configured and the period of the TDD pattern is P, the information value indicating the pattern period configuration in the first information ranges from 0 to 15, and each value corresponds to a period configuration for one pattern. Among them, when the SCS is 15k, 30k, 60k, or 120k, the second information indicates the available resources within the period P.

[0421] Specifically, when (pre-configured) one TDD pattern is configured, the period of the TDD pattern is P.

[0422] Optionally, the value of the third information ranges from 0 to 15, and actually only 0 - 8 (a total of 9 single periods) are used, and the remaining 9 - 15 are used for the case of configuring two TDD patterns.

[0423] Optionally, the meaning of the resource information is as follows:

[0424] (1) SCS = 15k:

[0430] (4) SCS = 120k:

[0431] The resource information Z = 7 bits indicates the available resources within the period P, and its indication accuracy is 1 slot.

[0432] 2. When (pre-configured) two TDD patterns are configured, the periods of the two TDD patterns are P1 and P2 respectively, and P1 + P2 ≤ 5ms:

[0433] Optionally, the value of the fourth information ranges from 0 to 15, and each value corresponds to a period configuration for two patterns.

[0434] Optionally, the meaning of the resource information is as follows:

[0435] If two TDD patterns are configured, with the periods of the TDD patterns being P1 and P2, and P1 + P2 ≤ 5 ms, the value of the information indicating the pattern period configuration when configuring two TDD patterns in the first information ranges from 0 to 15, and each value corresponds to a period configuration for two patterns. Among them: when SCS is 15k or 30k, the second information indicates the available resources of P1 and P2, or 4 bits are used in the second information to indicate the available resources of P1, and 3 bits are used to indicate the available resources of P2.

[0436] (1) SCS = 15k:

[0437] The high 4 bits of the 7-bit resource information Z are used to indicate the available resources of P1, and the low 3 bits are used to indicate the available resources of P2, with the indication accuracy being 1 slot for both.

[0438] Alternatively, the 7-bit combined coding indicates the available resources of P1 + P2, with the indication accuracy being 1 slot.

[0439] (2) SCS = 30k:

[0440] The high 4 bits of the 7-bit resource information Z are used to indicate the available resources of P1, and the low 3 bits are used to indicate the available resources of P2, with the indication accuracy being 1 slot for both.

Among them: when SCS is 60k, the second information indicates the available resources of P1 and P2.

[0444] Specifically, the 7-bit combined coding of the resource information Z indicates the available resources of P1 + P2, with the indication accuracy being 1 slot.

[0445] (4) SCS = 120k:

[0446] 1) If two TDD patterns are configured, with the periods of the TDD patterns being P1 and P2, and when P1 + P2 ≤ 4 ms, the value of the information indicating the pattern period configuration when two TDD patterns are configured in the first information ranges from 0 to 8, and each value corresponds to a period configuration for two patterns. Among them, when the SCS is 120k, the second information indicates the available resources of P1 and P2.

[0447] Specifically, when P1 + P2 ≤ 4 ms, the value of the fourth information ranges from 0 to 8.

[0448] Let the available resource indication accuracy of any one of P1 or P2 be 2 slots, and the other be 1 slot. Then, the resource information Z = 7 bits is used for joint coding to indicate the available resources of P1 + P2.

[0449] 2) If two TDD patterns are configured, with the periods of the TDD patterns being P1 and P2, and when 4 ms ≤ P1 + P2 ≤ 5 ms, the value of the information indicating the pattern period configuration when two TDD patterns are configured in the first information ranges from 9 to 13, and each value corresponds to a period configuration for two patterns. Among them, when the SCS is 120k, the second information indicates the available resources of P1 and P2.

[0450] Specifically, when 4 ms < P1 + P2 ≤ 5 ms, the value of the fourth information ranges from 9 to 13.

[0451] Let the available resource indication accuracy of both P1 and P2 be 2 slots. Then, the resource information Z = 7 bits is used for joint coding to indicate the available resources of P1 + P2.

[0452] 3. When (pre-configured) two TDD patterns are configured, with the periods of the two TDD patterns being P1 and P2 respectively, and when P1 + P2 ≥ 10 ms:

[0453] Optionally, the value of the fourth information ranges from 14 to 15, and the value of the third information ranges from 9 to 15. Each value or multiple values correspond to a period configuration for two patterns.

[0454] Optionally, the meaning of the resource information is as follows:

[0455] (1) SCS = 15k:

[0456] 1) If two TDD patterns are configured, with the periods of the TDD patterns being P1 and P2, P1 = 5 ms, P2 = 5 ms, and when 10 ms ≤ P1 + P2, the value of the information indicating the pattern period configuration when configuring two TDD patterns in the first information is 14. Each value or multi - value corresponds to a period configuration for two patterns. Among them, when the SCS is 15 kHz, the second information indicates the available resources of P1 and P2, or, in the second information, 4 bits are used to indicate the available resources of P1, and 3 bits are used to indicate the available resources of P2.

[0457] Specifically, P1 = 5 ms, P2 = 5 ms, and the value of the fourth information is 14.

[0458] The high 4 bits of the 7 - bit resource information Z are used to indicate the available resources of P1, and the low 3 bits are used to indicate the available resources of P2. The indication accuracy is 1 slot for both.

[0459] Or, 7 - bit joint encoding indicates the available resources of P1 + P2, and its indication accuracy is 1 slot.

[0460] 2) If two TDD patterns are configured, with the periods of the TDD patterns being P1 and P2, P1 = 10 ms, P2 = 10 ms, and when 10 ms ≤ P1 + P2, the value of the information indicating the pattern period configuration when configuring two TDD patterns in the first information is 15. Each value or multi - value corresponds to a period configuration for two patterns. Among them, when the SCS is 15 kHz, the second information indicates the available resources of P1 and P2.

[0461] Specifically, P1 = 10 ms, P2 = 10 ms, and the value of the fourth information is 15.

[0462] The 7 - bit resource information Z jointly encodes to indicate the available resources of P1 + P2, and its indication accuracy is 1 slot.

[0463] For SCS being 30 kHz or 60 kHz:

[0464] If two TDD patterns are configured, with the periods of the TDD patterns being P1 and P2, P1 = 5 ms, P2 = 5 ms, and when 10 ms ≤ P1 + P2, the value of the information indicating the pattern period configuration when configuring two TDD patterns in the first information is 14. Each value or multi - value corresponds to a period configuration for two patterns. Among them, when the SCS is 30 kHz or 60 kHz, the second information indicates the available resources of P1 and P2.

[0465] If 2 TDD patterns are configured, the periods of the TDD patterns are P1 and P2, P1 = 10 ms, P2 = 10 ms, and when 10 ms ≤ P1 + P2, the value of the information indicating the pattern period configuration when configuring 2 TDD patterns in the first information is 15, and each value or multi - value corresponds to a period configuration for 2 patterns. Among them, when SCS is 30k or 60k, the second information indicates the available resources of P1 and P2.

[0466] (2) SCS = 30k:

[0467] P1 = 5 ms, P2 = 5 ms, and the value of the fourth information is 14.

[0468] The resource information Z = 7 - bit jointly encodes to indicate the available resources of P1 + P2, and its indication accuracy is 1 slot.

[0469] P1 = 10 ms, P2 = 10 ms, and the value of the fourth information is 15.

[0470] Let the indication accuracies of the available resources of P1 and P2 both be 2 slots, then the resource information Z = 7 - bit jointly encodes to indicate the available resources of P1 + P2.

[0471] (3) SCS = 60k:

[0472] P1 = 5 ms, P2 = 5 ms, and the value of the fourth information is 14.

[0473] Let the indication accuracies of the available resources of P1 and P2 both be 2 slots, then the resource information Z = 7 - bit jointly encodes to indicate the available resources of P1 + P2.

[0474] P1 = 10 ms, P2 = 10 ms, and the value of the fourth information is 15.

[0475] Let the indication accuracies of the available resources of P1 and P2 both be 4 slots, then the resource information Z = 7 - bit jointly encodes to indicate the available resources of P1 + P2.

[0476] (4) SCS = 120k:

[0477] 1) If 2 TDD patterns are configured, with the periods of the TDD patterns being P1 and P2, P1 = 5 ms, P2 = 5 ms, and when 10 ms ≤ P1 + P2, the value of the information indicating the pattern period configuration in the first information when 2 TDD patterns are configured is 14 - 15, and the value of the information indicating the pattern period configuration in the first information when 1 TDD pattern is configured is 9. Each value or multi - value corresponds to a period configuration for 2 patterns. Among them, when SCS is 120k, the second information indicates the available resources of P1 and P2.

[0478] Specifically, P1 = 5 ms, P2 = 5 ms. Assuming that the number of available resources in each of P1 and P2 ≤ 32, the value of the fourth information is 14 - 15, and the value of the third information is 9.

[0479] 2) If 2 TDD patterns are configured, with the periods of the TDD patterns being P1 and P2, P1 = 5 ms, P2 = 5 ms, and when 10 ms ≤ P1 + P2, the value of the information indicating the pattern period configuration in the first information when 2 TDD patterns are configured is 14 - 15, and the value of the information indicating the pattern period configuration in the first information when 1 TDD pattern is configured is 9. Each value or multi - value corresponds to a period configuration for 2 patterns. Among them, when SCS is 120k, in the available resources of P1 and P2 indicated by the second information:

[0480] If only one of P1 and P2 has available resources, the value of the information indicating the pattern period configuration in the first information when 2 TDD patterns are configured is 14; if both P1 and P2 have available resources, the value of the information indicating the pattern period configuration in the first information when 2 TDD patterns are configured is 15, and the value of the information indicating the pattern period configuration in the first information when 1 TDD pattern is configured is 9.

[0481] If only one of P1 and P2 has available resources, the value of the fourth information is 14.

[0482] The resource information Z = 7 - bit jointly encodes to indicate the available resources, and its indication accuracy is 1 slot.

[0483] If both P1 and P2 have available resources, the value of the fourth information is 15, and the value of the third information is 9.

[0484] Let the indication accuracy of the available resources of P1 and P2 both be 2 slots, then the resource information Z = 7 - bit jointly encodes to indicate the available resources of P1 + P2. At this time, one period configuration corresponds to two code points.

[0485] 2) If two TDD patterns are configured, the periods of the TDD patterns are P1 and P2, P1 = 10 ms, P2 = 10 ms, and when 10 ms ≤ P1 + P2, the value of the information indicating the pattern period configuration in the first information when two TDD patterns are configured is the same as the value of the information indicating the pattern period configuration in the first information when one TDD pattern is configured, which is 10 - 14. Each value or multiple values correspond to a period configuration for two patterns. Among them, when the SCS is 120k, the second information indicates the available resources of P1 and P2.

[0486] P1 = 10 ms, P2 = 10 ms. Assuming that the number of available resources in each of P1 and P2 ≤ 64, the value of the fourth information is the same as the value of the third information, which is 10 - 14.

[0487] When two TDD patterns are configured, the periods of the TDD patterns are P1 and P2, P1 = 10 ms, P2 = 10 ms, and when 10 ms ≤ P1 + P2, the value of the first information is 26 - 30. Each value or multiple values correspond to a period configuration for two patterns. Among them, when the SCS is 120k, the second information indicates the available resources of P1 and P2:

[0488] Only one of P1 and P2 has available resources. The value of the information indicating the pattern period configuration in the first information when two TDD patterns are configured is the same as the value of the information indicating the pattern period configuration in the first information when one TDD pattern is configured, which is 10. Both P1 and P2 have available resources. The value of the information indicating the pattern period configuration in the first information when two TDD patterns are configured is the same as the value of the information indicating the pattern period configuration in the first information when one TDD pattern is configured, which is 11 - 14.

[0489] Specifically, assuming that only one of P1 and P2 has available resources, the value of the fourth information is the same as the value of the third information, which is 10.

[0490] The resource information Z = 7 bits is jointly encoded to indicate the available resources, and its indication accuracy is 1 slot.

[0491] Both P1 and P2 have available resources. The value of the fourth information is the same as the value of the third information, which is 11 - 14.

[0492] Let the available resource indication accuracy of any one of P1 or P2 be 2 slots, and that of the other be 4 slots. Then, the available resources of P1 + P2 are jointly encoded and indicated by the resource information Z = 7 bits. At this time, one cycle configuration corresponds to four code points.

Among them, the non-volatile memory may be a read-only memory (ROM), a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM), or a flash memory. The volatile memory may be a random access memory (RAM), which is used as an external cache. By way of example but not limitation, many forms of RAM are available, such as static random access memory (SRAM), dynamic random access memory (DRAM), synchronous dynamic random access memory (SDRAM), double data rate SDRAM (DDR SDRAM), enhanced synchronous dynamic random access memory (ESDRAM), synchlink DRAM (SLDRAM), and direct rambus RAM (DRRAM). The memory 302 of the systems and methods described in the embodiments of the present invention is intended to include but not be limited to these and any other suitable types of memory.

[0638] In some embodiments, the memory 302 stores the following elements, executable modules, or data structures, or subsets thereof, or extended sets thereof: an operating system 3021 and an application program 3022.

[0639] Among them, the operating system 3021 includes various system programs, such as a framework layer, a core library layer, a driver layer, etc., for implementing various basic services and processing hardware-based tasks. The application program 3022 includes various application programs, such as a media player and a browser, etc., for implementing various application services.

[0640] In an embodiment of the present invention, by invoking the program or instruction stored in the memory 302, specifically, it may be the program or instruction stored in the application program 3022, the steps described in the above method are implemented when executed.

[0641] The terminal provided by the embodiment of the present invention can execute the above measurement reporting method embodiment, and its implementation principle and technical effect are similar, which will not be elaborated here in this embodiment.

[0642] In an embodiment of the present invention, a computer-readable storage medium is provided, and the computer-readable storage medium stores a computer program for executing the method of transmitting sidelink resource indication information described above.

[0643] In summary, in the technical solution provided by the embodiment of the present invention, by designing the bit encoding method in the parameter SL-TDD-Config: separate encoding or joint encoding, and the indication method: joint indication or segmented indication, while the parameter indicates the number of available resources, a relatively high indication accuracy is ensured as much as possible, enabling the parameter SL-TDD-Config to indicate the available resources of different TDD mode periods under different SCSs with a relatively high indication accuracy.

[0644] The following will be further illustrated with examples.

[0645] 1) SL-TDD-Config uses a total of T bits

[0646] a) Specification: The ways for a user to obtain SL-TDD-Config include at least one of the following

[0647] i. Configuration: It can be that the base station directly configures SL-TDD-Config to the user through SL SIB or RRC

[0648] ii. Pre-configuration: It can also be that SL-TDD-Config is directly pre-configured to the user in the pre-configuration

[0649] iii. Self-determination: It is also that the user infers SL-TDD-Config by himself according to the TDD configuration information obtained from the base station configuration, pre-configuration or PC5-RRC, such as TDD-UL-DL-ConfigCommon

[0650] iv. Other user indication: It can also be obtained from the received SL information, such as SL MIB or PC5-RRC. For example, UE2 receives the SL MIB of UE1, and the SL MIB carries SL-TDD-Config.

[0651] b) Description: In the present invention, the statement 'obtained 1 or 2 TDD patterns' may specifically mean that 1 or 2 TDD patterns are indicated in the obtained SL-TDD-Config (where 'obtained' has the meanings described above: configured, pre-configured, determined by itself, indicated by other users), or it may mean that 1 or 2 TDD patterns are indicated in the obtained TDD configuration information.

[0652] c) Note: The present invention can be used for at least one of the following purposes

[0653] i. How to set the indicated content of SL-TDD-Config according to the obtained TDD configuration information

[0654] ii. If SL-TDD-Config is obtained, how to understand the meaning indicated in SL-TDD-Config

[0655] 2) For all the following solutions (taking Z = 8bit as an example), either 4bit + 4bit segmented indication or 8bit combined indication can be selected. The same applies to Z = 7bit.

[0656] 3) For the case of segmented indication, it can be understood that Z = Z1 + Z2, and there are multiple permutations and combinations of Z1 and Z2. Taking Z = 8bit as an example, 4 + 4 / 3 + 5 / 5 + 3 / 2 + 6 / 6 + 2 / 1 + 7 / 7 + 1 can all work, but the description in the specification takes 4 + 4 or 4 + 3 as examples.

[0657]

Solution 1: For the Z corresponding to resource information = 8bit, the pattern number and pattern period are jointly encoded, and the indication accuracy of the resource information is not greater than 2 slots. Advantage: accuracy &lt;= 2 slots

[0658] 1. The pattern number and pattern period are jointly encoded. The first information indicates the pattern number and pattern period. The first information is X + Y = 5bit, with values from 0 to 31. The resource information Z = 8bit is used to indicate the available resources, that is, T = 13bit.

[0659] A. The resource information indicates the number of available resources.

[0660] B. The available resources can be uplink resources, and / or resources that meet at least the preset requirements.

[0661] i. Preset requirements: The resources from symbol S to symbol S + L - 1 are uplink resources. For example, S = 2, L = 7. If the resources from symbol 3 to 11 in a slot are uplink resources, then...

[0662] The slot does not meet the requirements; if the symbols 2-9 in a slot are uplink resources, then the slot meets the requirements

[0663] C. Optionally, the indication accuracy of the resource information at this time is not greater than 2 slots

[0664] D. The meaning of the indicated content is related to the SCS of the sidelink transmission

[0665] When 1 TDD pattern is obtained, the period of the TDD pattern is P

[0666] ■ Optionally, the first information takes values from 0 to 8, and each value corresponds to a period configuration when there is 1 pattern

[0667] e.g. When the code point value is 8, it corresponds to the configuration with a period of 10 ms when configuring 1 pattern

[0668] ■ Optionally, the meaning of the resource information is as follows

[0669] a) When SCS = 15k

[0670] The resource information Z = 8 bits indicates the available resources within the period P, and its indication accuracy is 1 slot

[0671] e.g. When SCS = 15k and the period configuration is 10 ms, there are 10 slots in total within the period, and there are 11 cases of available resources. When corresponding to 0-10 among 256 code points indicated by 8 bits, they respectively correspond to the number of available resource slots. For example, when the 8-bit indicated code point is 10, it means the available resources are 10 slots

[0672] b) When SCS = 30k

[0673] The resource information Z = 8 bits indicates the available resources within the period P, and its indication accuracy is 1 slot

[0674] c) When SCS = 60k

[0675] The resource information Z = 8 bits indicates the available resources within the period P, and its indication accuracy is 1 slot

[0676] d) When SCS = 120k

[0677] The resource information Z = 8 bits indicates the available resources within the period P, and its indication accuracy is 1 slot. This can be abstracted as: there is only one TDD pattern, the period is P, and SCS = 2 μ *15 kHz. If the value indicated by the resource information is n

[0678] Indicates that there are n available resources within period P;

[0679] Optionally, the range of the number of resources indicated by the resource information at this time is 0 to min(2 Z - 1, P * 2 μ )

[0680] Or

[0681] Indicates that there are n + 1 available resources within period P

[0682] Optionally, the range of the number of resources indicated by the resource information at this time is 1 to min(2 Z , P * 2 μ )

[0683] Optionally, the indication accuracy of the resource information at this time is 1 slot

[0684] When 2 TDD patterns are obtained, the periods of the two TDD patterns are P1

[0685] and P2, and when P1 + P2 <= 5 ms

[0686] ■ Optionally, the first information takes values from 9 to 22, and each value corresponds to a period configuration when there are 2 patterns

[0687] For example, when the code point takes the value 22 and corresponds to the configuration of 2 patterns, P1 = 1 ms and P2 = 4 ms.

[0688] ■ Optionally, the meaning of the resource information is as follows

[0689] a) When SCS = 15k

[0690] The high 4 bits of the 8 - bit resource information Z are used to indicate the available resources within period P1, and the low 4

[0691] bits are used to indicate the available resources within period P2, and the indication accuracy is 1 slot for both

[0692] For example, when SCS = 15k and the period configuration is P1 = 10 ms and P2 = 10 ms, then there are 10 slots in each period, and there are a total of 11 cases of available resources in each period. At this time, the high 4 bits indicate 16 code points (0 - 15), and let code points 0 - 10 represent the available resources in P1; the low 4 bits indicate 16 code points (0 - 15), and let code points 0 - 10 represent the available resources in P2. For example, the code point 10 indicated by the high 4 bits means that the available resources in P1 are 10 slots, and the code point 10 indicated by the low 4 bits means that the available resources in P2 are 10 slots.

[0693] This can be abstracted as: there are 2 TDD patterns with periods P1 and P2 respectively, and 4 bits + 4 bits respectively indicate the available resources of P1 and P2.

[0694] Assume that the bits corresponding to indicating the available resources within P1 in the resource information are called the first resource information, and the bits corresponding to indicating the available resources within P2 are called the second resource information.

[0695] If the value indicated by the first resource information is n,

[0696] it means that there are n available resources within the period P1;

[0697] Optionally, at this time, the range of the number of resources indicated by the first resource information is 0 to min(2 Z - 1, P * 2 μ )

[0698] Or

[0699] it means that there are n + 1 available resources within the period P1

[0700] Optionally, at this time, the range of the number of resources indicated by the first resource information is 1 to min(2 Z , P * 2 μ )

[0701] Optionally, at this time, the indication accuracy of the first resource information is 1 slot

[0702] And or

[0703] If the value indicated by the second resource information is n,

[0704] it means that there are n available resources within the period P2;

[0705] Optionally, at this time, the range of the number of resources indicated by the second resource information is 0 to min(2 Z - 1, P * 2 μ )

[0706] Or

[0707] it means that there are n + 1 available resources within the period P2

[0708] Optionally, at this time, the range of the number of resources indicated by the second resource information is 1 to min(2 Z , P * 2 μ )

[0709] Optionally, at this time, the indication accuracy of the second resource information is 1 slot

[0710] Or, 8 - bit combined coding indicates the available resources within the period P1 + P2, and its indication accuracy is 1 slot

[0711] For example, when SCS = 15k and the cycle configuration is P1 = 10ms, P2 = 10ms, there are 10 slots in each cycle, and the total available resources are 11 * 11 = 121 types, corresponding to 0 - 120 among the 256 code points indicated by 8 bits. For example, code point 120 means that the available resources in P1 are 10 slots and the available resources in P2 are 10 slots.

[0712] This can be abstracted as: there are 2 TDD patterns with cycles P1 and P2 respectively, and 8 - bit combined coding indicates the available resources.

[0713] Optionally, if the value n indicated by the resource information is in the range of 0 to P1 * 2 μ when

[0714] it means that there are n or n + 1 available resources only within pattern 1;

[0715] Optionally, if the value n indicated by the resource information is in the range of P1 * 2 μ + 1 to P1 * 2 μ + P2 * 2 μ + 1,

[0716] it means that there are n - P1 * 2 μ - 1 or n - P1 * 2 μ available resources only within pattern 2. Optionally, if the value n indicated by the resource information is in the range of P1 * 2 μ + P2 * 2 μ + 2 to (P1 * 2 μ + 1) * (P2 * 2 μ + 1),

[0717] it means that there are n1 available resources in pattern 1 and n2 available resources in pattern 2. Optionally, the indication accuracy of the resource information is 1 slot at this time.

[0718] b) When SCS = 30k

[0719] The high 4 bits of the 8 - bit resource information Z are used to indicate the available resources within cycle P1, and the low 4 bits are used to indicate the available resources within cycle P2, and the indication accuracy is 1 slot for both.

[0720] Or, 8 - bit combined coding indicates the available resources within cycle P1 + P2, and its indication accuracy is 1 slot.

[0721] c) When SCS = 60k

[0722] The high 4 bits of the 8-bit resource information Z are used to indicate the available resources within period P1, and the low 4 bits are used to indicate the available resources within period P2. The indication accuracy is 1 slot for both.

[0723] Alternatively, the 8-bit combined coding indicates the available resources within period P1+P2, and its indication accuracy is 1 slot.

[0724] d) When SCS = 120k

[0725] 1. When P1+P2 <= 2.5ms, the first information takes values from 9 to 14

[0726] The high 4 bits of the 8-bit resource information Z are used to indicate the available resources within period P1, and the low 4 bits are used to indicate the available resources within period P2. The indication accuracy is 1 slot for both.

[0727] Alternatively, the 8-bit combined coding indicates the available resources within period P1+P2, and its indication accuracy is 1 slot.

[0728] 2. When 2.5ms < P1+P2 <= 5ms

[0729] A. When P1 = 2ms and P2 = 2ms, the first information takes the value 15

[0730] The high 4 bits of the 8-bit resource information Z are used to indicate the available resources within period P1, and the low 4 bits are used to indicate the available resources within period P2. The indication accuracy is 1 slot for both.

[0731] Alternatively, the 8-bit combined coding indicates the available resources within period P1+P2, and its indication accuracy is 1 slot.

[0732] B. Otherwise, the value range of the first information is from 16 to 22

[0733] Let the indication accuracy of the available resources of any one of P1 or P2 be 2 slots, and the indication accuracy of the other be 1 slot. Then the 8-bit combined coding of the resource information Z is used to indicate the available resources within period P1+P2.

[0734] When 2 TDD patterns are obtained, the periods of the two TDD patterns are P1 and P2 respectively, and P1+P2 >= 10ms

[0735] ■ Optionally, the first information takes values from 23 to 31, and each value or multiple values correspond to a period configuration when there are 2 patterns.

[0736] For example, when SCS = 120k and the code point values from 26 to 30 all correspond to the configuration of 2 patterns, P1 = 10ms and P2 = 10ms.

[0737] ■ Optionally, the meaning of the resource information is as follows

[0738] a) When SCS = 15k

[0739] For the resource information Z = 8 bits, the upper 4 bits are used to indicate the available resources within the period P1, and the lower 4 bits are used to indicate the available resources within the period P2. The indication accuracy is 1 slot for both.

[0740] Alternatively, the 8 - bit combined coding indicates the available resources within the period P1 + P2, and its indication accuracy is 1 slot.

[0741] b) When SCS = 30k

[0742] 1. P1 = 5ms, P2 = 5ms, and the first information value is 23

[0743] For the resource information Z = 8 bits, the upper 4 bits are used to indicate the available resources within the period P1, and the lower 4 bits are used to indicate the available resources within the period P2. The indication accuracy is 1 slot for both.

[0744] Alternatively, the 8 - bit combined coding indicates the available resources within the period P1 + P2, and its indication accuracy is 1 slot.

[0745] 2. P1 = 10ms, P2 = 10ms, and the first information value is 24

[0746] If the indication accuracy of the available resources of any one of P1 or P2 is 2 slots and the other is 1 slot, then the 8 - bit combined coding of the resource information Z is used to indicate the available resources within the period P1 + P2.

[0747] c) When SCS = 60k

[0748] 1. P1 = 5ms, P2 = 5ms, and the first information value is 23

[0749] If the indication accuracy of the available resources of any one of P1 or P2 is 2 slots and the other is 1 slot, then the 8 - bit combined coding of the resource information Z is used to indicate the available resources within the period P1 + P2.

[0750] 2. P1 = 10ms, P2 = 10ms, and the first information value is 24 - 25

[0751] Let the available resource indication precision of both P1 and P2 be 2 slots. Then, the available resources within the combined period P1 + P2 are indicated by joint encoding with the resource information Z = 8 bits. At this time, one period configuration corresponds to two code points.

[0752] d) When SCS = 120k

[0753] 1. P1 = 5ms, P2 = 5ms, and the first information value ranges from 23 to 25

[0754] A. If only one of P1 and P2 has available resources, and the first information value is 23, the available resources are indicated by joint encoding with the resource information Z = 8 bits, and its indication precision is 1 slot.

[0755] For example, when SCS = 120k and the period configuration is P1 = 5ms, P2 = 5ms, there are a total of 40 slots within 1 period, and the available resources total 41 + 41 - 1 = 81 (subtracting the case where both periods are 0 slots which is repeated). This corresponds to 0 - 81 among the 256 code points indicated by 8 bits. For example, code point 40 indicates that the available resources in P1 are 40 slots and the available resources in P2 are 0 slots; code point 81 indicates that the available resources in P2 are 41 slots and the available resources in P1 are 0 slots.

[0756] B. If both P1 and P2 have available resources, the first information value ranges from 24 to 25

[0757] Let the available resource indication precision of both P1 and P2 be 2 slots. Then, the available resources within the combined period P1 + P2 are indicated by joint encoding with the resource information Z = 8 bits. At this time, one period configuration corresponds to two code points.

[0758] For example, when SCS = 120k and the period configuration is P1 = 5ms, P2 = 5ms, there are 40 slots in each period, and the indication precision is 2 slots. Then the available resources total 21 * 21 - 1 = 440. When the first value is 24, this corresponds to 0 - 219 among the 256 code points indicated by 8 bits, and when the first value is 25, it also corresponds to 0 - 219 among the 256 code points indicated by 8 bits. For example, when the first value is 25, code point 219 indicates that the available resources in P1 are 40 slots and the available resources in P2 are 40 slots.

[0759] 2. P1 = 10ms, P2 = 10ms. Assume that the number of available resources in P1 and P2 respectively <= 64, and the first information value ranges from 26 to 30

[0760] A. Assume that only one of P1 and P2 has available resources, and the first information value is 26

[0761] The resource information Z = 8-bit jointly encodes to indicate available resources, and its indication accuracy is 1 slot

[0762] B. There are available resources in both P1 and P2. When the first information takes values from 27 to 30, the available resource indication accuracies of P1 and P2 are both 2 slots. Then, the resource information Z = 8-bit jointly encodes to indicate the available resources within the period P1 + P2. At this time, one period configuration corresponds to four code points

[0763]

Solution 2: Z corresponding to the resource information = 7 bits, the number of patterns and the pattern period are jointly encoded, and the indication accuracy of the resource information is no greater than 4 slots. Advantage: Compared with Solution 1, it reduces the overhead by 1 bit

[0764] 2. The number of patterns and the pattern period are jointly encoded. The first information indicates the number of patterns and the pattern period. The first information is X + Y = 5 bits, taking values from 0 to 31. The resource information Z = 7 bits is used to indicate available resources, that is, T = 12 bits

[0765] A. The resource information indicates the number of available resources

[0766] B. The available resources can be uplink resources, and / or resources that meet at least the preset requirements

[0767] i. Preset requirements: The resources from symbol S to symbol S + L - 1 are uplink resources

[0768] For example, S = 2, L = 7. If the resources from symbol 3 to symbol 11 in a slot are uplink resources, then this slot does not meet the requirements; if the resources from symbol 2 to symbol 9 in a slot are uplink resources, then this slot meets the requirements

[0769] C. Optionally, at this time, the indication accuracy of the resource information is no greater than 4 slots

[0770] D. The meaning of the indicated content is related to the SCS of sidelink transmission

[0772] ■ Optionally, the first information takes values from 0 to 8, and each value corresponds to a period configuration when there is 1 pattern

[0773] ■ Optionally, the meaning of the resource information is as follows
