Detailed Description

In order to facilitate understanding of the embodiments of the present invention, the following technical points are introduced below:

1、NR TDD：

the current NR TDD configuration is very flexible, the number of uplink resources in one TDD pattern may be 0 to 80, and the TDD configuration may include 1 or 2 TDD patterns. The period of one TDD pattern may be 9. The periods (P1 and P2) of the two TDD patterns may be the same or different, as shown in tables 1-3.

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

In addition, the number of slots for transmitting the SL synchronization signals is very flexible, and one synchronization resource comprises 1-64 slots for transmitting the sidelink SSB.

Table 1: periodicity of NR-TDD configuration (Table 1: Periodicity of NR TDD-configuration with single TDD pattern) in Single TDD mode

Table 2: periodicity of NR-TDD configuration (Table: 2: Periodicity of NR TDD-config with up to two TDD patterns) in dual TDD mode

Table 3: periodic combination of NR-TDD profiles P (Table 3: Combinations of the behaviour of NR TDD-configuration P)

2: introduction to X, Y, Z:

the TDD configuration in NR networking is indicated as follows:

an X bit (bit) indication mode + a Y bit indication periodicity + a Z bit indication uplink time slot (X bits to indication patterns + Y bits to indication periodicity + Z bits to indication UL slots).

1) X and Y separately encode an indication:

the X bit indicates the pattern type, i.e., whether the current TDD configuration includes 1 or 2 patterns; the Y bit indicates the corresponding TDD mode period configuration under the current pattern. For example, X ═ 1bit is used to indicate a pattern type, when the TDD configuration includes 1 pattern, the TDD mode period configuration has 9 types, Y ═ 4bit may indicate the mode period configuration, when the TDD configuration includes 2 patterns, the TDD mode period configuration has 16 types, and Y ═ 4bit may indicate the mode period configuration.

2) X and Y jointly encode an indication:

the total (X + Y) bit is used to indicate TDD mode period configuration. For example, X + Y is 5 bits, and all mode period configurations are 25 in total, and may be jointly indicated by 5 bits.

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

For sidelink, a Long Term Evolution (LTE) system supports sidelink (or translated into sidelink, etc.) for direct data transmission between terminals (User Equipment, UE) without passing through network Equipment.

The UE transmits Sidelink Control Information (SCI) through a Physical Sidelink Control Channel (PSCCH), and schedules transmission of a Physical Sidelink Shared Channel (PSCCH) to transmit data. The transmission is performed in a broadcast manner, and the receiving end does not feed back whether the reception is successful to the transmitting end.

The LTE sidelink design supports two resource allocation modes, namely a Scheduled resource allocation (Scheduled resource allocation) mode-1 (commonly referred to as mode-1) and an autonomous resource selection (autonomous resource selection) mode. The former is controlled by network side equipment and allocates resources for each UE, and the latter is selected by the UE autonomously.

LTE supports sidelink Carrier Aggregation (CA). Unlike the Uu interface, the CA of LTE sidelink has no difference between Primary Component Carrier (PCC) and Secondary Component Carrier (SCC). The UE in autonomous resource selection mode performs resource sensing (sensing) and resource reservation independently on each CC.

The design of the LTE sidelink is suitable for specific public safety affairs (emergency communication in disaster places such as fire places or earthquakes), vehicle to internet (V2X) communication and the like. The internet of vehicles communication includes various services, such as: basic security class communication, advanced (automated) driving, formation, sensor extension, etc. Since LTE sidelink supports only broadcast communication, and is therefore mainly used for basic security class communication, other advanced V2X services will be supported by NR sidelink.

The 5G NR system can be used for an operating frequency band above 6GHz which is not supported by LTE, and supports larger operating bandwidth, and the NR system also supports Sidelink interface communication of direct communication between terminals.

The current sidelink transmission mainly comprises broadcast, multicast and unicast transmission forms. Unicast is the transmission of one to one as the name implies, multicast is the transmission of one to many, and broadcast is the transmission of one to many, but broadcast does not have the concept that the UE belongs to the same group.

The PSCCH on the sildenk carries the SCI, which is used to schedule the psch. Transmission resources may be indicated in the SCI and reserved for future transmissions. The secondary link Feedback Channel (PSFCH) is used for feeding back the Sidelink Hybrid automatic repeat request acknowledgement (HARQ-ACK) information. After determining the sidelink HARQ information, the user may further send the sidelink HARQ information to the base station through a PUCCH or a PUSCH.

The prior art is disadvantageous in that currently, a SL Master Information Block (MIB) may be used to indicate TDD configuration (configuration) with a limited number of bits, but 25 periodic configurations need to be indicated, and each periodic configuration involves a different SCS for indicating SL-TDD-configuration with a limited number of bits. Therefore, the bit encoding and indicating manner in the SL-TDD-Config needs to be designed so that the parameter can ensure higher indicating accuracy as much as possible while indicating available resources.

That is, in the sildelink communication, when the TDD configuration includes two TDD patterns P1 and P2, the bit number in the SL-TDD-Config is not sufficient to indicate the number of available resources, so the bit encoding and indicating manner in the SL-TDD-Config needs to be designed, so that the parameter can indicate the available resources while ensuring higher indicating accuracy as much as possible. Based on this, the present invention provides a transmission scheme for configuring indication information, and it is easy to understand that the scheme may be used for LTE sidelink, NR sidelink, and their evolution technologies. The following describes embodiments of the present invention with reference to the drawings.

Fig. 1 is a schematic flowchart of an implementation process of a method for transmitting sidelink resource indication information, as shown in the figure, the method may include:

step 101, transmitting sidelink resource indication information, wherein the indication information comprises at least one of first information indicating mode number and mode period configuration, and second information indicating available resources.

The general description is given below, and examples are given below.

In a specific implementation, for the sidelink resource indication information, the terminal may send or receive the information, and for the network side device, such as the base station, the information may be sent.

In specific implementation, the unit of the mode period value can be ms or slot, and the scheme provided by the embodiment of the invention mainly exemplifies ms, but obviously, the method can also be used for the case that the unit is slot, and at this time, the value only needs to be converted by one unit.

In a specific implementation, for example, the method for acquiring the SL-TDD-Config includes at least one of the following:

i. the communication device obtains by configuration: in this way, the base station can directly configure the SL-TDD-Config to the terminal through the SL SIB or the RRC.

The communication device obtains by pre-configuration: for example, the SL-TDD-Config is preconfigured directly to the terminal in the preconfiguration.

The communication device itself determines: for example, the terminal self-infers SL-TDD-Config according to TDD configuration information, such as TDD-UL-DL-ConfigCommon, obtained from base station configuration or pre-configuration or PC 5-RRC.

The communication device indicates, by the other device: for example, the information may be derived from received SL information, e.g., obtained from SL MIB or PC5-RRC, e.g., UE2 received SL MIB of UE1, where SL MIB carries SL-TDD-Config.

In the embodiment, when 1 or 2 TDD patterns are obtained in the application, 1 or 2 TDD patterns may be indicated in the SL-TDD-Config obtained (the obtaining means is as described above: configuration, pre-configuration, terminal self-determination, and other terminal indication), or 1 or 2 TDD patterns may be indicated in the obtained TDD configuration information.

By adopting the embodiment of the invention, how to set the instruction content of SL-TDD-Config can be determined according to the acquired TDD configuration information; and/or, if the SL-TDD-Config is acquired, it may be determined how to understand the meaning indicated in the SL-TDD-Config.

1. A relationship of the first information to the second information.

In an implementation, the first information indicates the mode number and the mode period configuration through a joint coding or an independent coding mode.

In an implementation, the second information indicates available resources by using a joint coding indication or a segmentation indication.

In a specific implementation, the two modes of the first information may be used in cooperation with the two modes of the second information, for example, the first information adopts joint coding, and the second information uses joint coding indication or segmentation indication; or, the second information adopts independent coding, and the second information uses joint coding indication or segmentation indication.

The embodiments provided in the embodiments of the present invention can also be freely combined, and the main combination is represented as:

1) freely combining the precisions under different SCS;

2) and a free combination of the first information encoding method and the second information indication method.

2. Implementation of the first information.

In a specific implementation, when the first information indicates the number of modes and the configuration of the mode period by independently encoding, at least one of the following cases may be included:

if the first bit corresponding to the number of the modes in the first information is a first value range, the second bit corresponding to the mode period configuration in the first information indicates two mode period configurations, or indicates one mode period configuration;

if the first bit corresponding to the number of the modes in the first information is the second value range, the second bit corresponding to the mode period configuration in the first information indicates two mode period configurations.

In a specific implementation, when the first information indicates the number of modes and the mode cycle configuration, the same mode cycle configuration may correspond to one or more first information values.

3. And implementation of the second information.

For the case of two pattern periods P1, P2, the first pattern period P1 and the second pattern period P2 may be the same or different, as will be given in the following examples, for example: examples when P1 is 1ms, P2 is 4ms, P1 is 10ms, and P2 is 10 ms.

1) Implementation of segment indication.

In implementation, when the second information indicates available resources, if there is a mode period and the mode period is configured to be P, and when a value indicated by the second information is n, it indicates that there are n available resources in the mode period P; or, when the value indicated by the second information is n, indicating that n + a available resources exist in the pattern period P.

In an implementation, when the second information indicates available resources by segmentation, if there are two pattern periods, and the pattern periods are the first pattern period P1 and the second pattern period P2, the first resource information is used to indicate available resources existing in the first pattern period, and/or the second resource information is used to indicate available resources existing in the second pattern period.

In a specific implementation, when the value indicated by the first resource information is n1, it indicates that there are n1 available resources in the first pattern period; alternatively, when the indicated value is n1, there are n1+ B available resources within the first pattern period P1;

and/or the presence of a gas in the gas,

when the second resource information indicates a value of n2, indicating that there are n2 available resources in the second pattern period; alternatively, when the indicated value is n2, there are n2+ C available resources within the second pattern period P2.

A. B, C is a positive integer, one possible value being 1.

2) Implementation of joint coding indication.

In an implementation, when the second information indicates available resources through joint coding, if there are two pattern periods, and the pattern periods are a first pattern period P1 and a second pattern period P2:

a value n of the second information indication is within a first range, indicating that there is a first number of available resources in a first mode period; or the like, or, alternatively,

a value n of the second information indication is within a second range indicating that there is a second number of available resources in a second mode period; or the like, or, alternatively,

the value n indicated by the second information is within a third range, indicating that a third number of available resources exist in the first mode period and a fourth number of available resources exist in the second mode period.

In a specific implementation, the first number is determined according to the value of n, and/or the second number is determined according to the value of n and the first pattern period P1.

When the first information and the second information are adopted, the following four schemes are adopted and relate to at least one of the following items:

1) SCS; 2) a value of the first information; 3) the number of modes; 4) and configuring a mode cycle.

Wherein: the values of mu are: 0. 1, 2 or 3, and Z has the value: the second information is used to indicate the number of bits used by n 2.

3. The second information indicates the number of modes and the mode period by a value n using a joint coding manner, wherein:

if there are two pattern periods, the pattern periods are the first pattern period P1 and the second pattern period P2, SCS 2^μ15kHz, then:

the indicated value is n, if n ranges from 0 to P1 x 2^μWhen there are n or n +1 available resources in mode 1; or the like, or, alternatively,

where L is a positive integer, for example, 64.

To round down. A1, a2, A3, a4 are positive integers, one possible value being 1.

The indicated accuracy of the second information is related to at least one of:

1)、SCS；

2) a value of the first information;

3) the number of modes;

4) and configuring a mode cycle.

The following provides a general description of example technical means, e.g., number of bits, used in the examples section.

In the embodiment of the present invention, at least one of the following is assumed:

1. when SCS is 30k, the number of available resources in each mode period is less than or equal to 16;

2. when SCS is 60k, the number of available resources in each mode period is less than or equal to 32;

3. when SCS is 120k, the number of available resources in each mode period is less than or equal to 64.

In an example, the first information and the second information in the indication information are indicated according to the following bit numbers:

5 bits are used for indicating the number of patterns and the period configuration of the patterns in the first information, and 8 bits are used for indicating available resources in the second information; or the like, or, alternatively,

5 bits are used for indicating the number of patterns and the period configuration of the patterns in the first information, and 7 bits are used for indicating available resources in the second information; or the like, or, alternatively,

1bit is used for indicating the number of patterns and 4 bits are used for indicating the period configuration of the patterns in the first information, and 8 bits are used for indicating available resources in the second information; or the like, or, alternatively,

1bit is used for indicating the number of patterns in the first information, 4 bits are used for indicating the period configuration of the patterns, and 7 bits are used for indicating available resources in the second information.

In the example, assume that SL-TDD-Config uses T bit in common;

in the following scheme, an example of Z ═ 8bit will be described, where a 4bit +4bit segmentation indication may be selected, and an 8bit joint indication may be selected, and Z ═ 7bit is the same, that is, even if only a description of the joint indication is available in a certain scheme, the segmentation indication may be actually selected.

For the case of segment indication, it is understood that Z1+ Z2, Z1 and Z2 may have a plurality of permutation combinations, and taking Z8 bit as an example, 4bit +4bit or 3bit +5bit or 5bit +3bit or 2bit +6bit or 6bit +2bit or 1bit +7bit or 7bit +1bit may implement the scheme in the embodiment of the present invention, and the specific example will be mainly described with 4bit +4bit or 4bit +3bit as an example.

It should be noted that, although T-12 and T-13 are taken as examples in the above example, it is easy to understand that, based on the indication of the number of bits, the more bits of information that can be carried, the more accurate indication can be performed; therefore, for example, if T is 14, and 1bit is added, a more accurate indication can be performed, but it is anticipated that, if the number of bits is sufficient, according to the technical solution provided by the embodiment of the present invention, under all SCS or periodic configurations, 1slot precision resource can be constantly used.

In addition, the number of bits is different, but the joint coding indication and the segmentation indication of the second information are technical means that can be adopted all the time. For example, T is 14, Z is 9 bits, and the 9 bits can be arranged and combined.

The following is a detailed description in four ways.

The first mode is that the number of patterns and the period configuration of the patterns are indicated by using 5 bits in the first information, and the implementation is performed when the available resources are indicated by using 8 bits in the second information.

In this way, the second information occupies Z ═ 8bit, and the first information adopts a joint coding mode, and the resource indication precision is not greater than 2 slot.

For example, the number of patterns and the periodic configuration of the patterns are jointly encoded, the first information indicates the number of patterns and the periodic configuration of the patterns, the first information may be X + Y ═ 5 bits, and values are 0 to 31, and the second information occupies Z ═ 8 bits to indicate available resources, that is, T ═ Z + X + Y ═ 13 bits. Wherein:

the second information indicating resources indicates the number of available resources;

further, the available resource may be an uplink resource, and/or a resource that meets at least a preset requirement;

further, the preset requirement means that the symbol S to the symbol S + L-1 are uplink resources;

for example, if a symbol 3-11 in a slot is an uplink resource, the slot does not meet the requirement; if the symbols 2-9 in a slot are uplink resources, the slot meets the requirement.

Optionally, at this time, the indication precision of the resource information is not greater than 2 slots.

It will be appreciated that the meaning of the indicated content is related to the SCS transmitting the sidelink.

1. If 1 TDD pattern is configured, and the period of the TDD pattern is P, the first information value is 0-8, and each value corresponds to one period configuration when 1 pattern is configured, where: the second information indicates available resources in the period P when the SCS is 15k, 30k, 60k, or 120 k.

Specifically, when 1 TDD pattern is configured (preconfigured), the period of the TDD pattern is P;

optionally, the first information value is 0 to 8, and each value corresponds to one cycle configuration when 1 pattern is selected.

For example, the code point value is 8, and the period is 10ms when 1 pattern is configured correspondingly.

Alternatively, the meaning of the resource information may specifically be as follows:

(1)SCS＝15k：

the resource information Z ═ 8bit indicates the available resources within the period P, and the indication precision thereof is 1 slot.

For example, when the SCS is 15k and the period is configured with 10ms, there are 10 slots in the period, and the available resources are 11 types, and corresponding to 8 bits, 0 to 10 of the 256 code points are indicated, for example, code point 10 indicates that the available resources are 10 slots.

(2)SCS＝30k：

(3)SCS＝60k：

(4)SCS＝120k：

2. If 2 TDD patterns are configured, the TDD patterns have periods P1 and P2, and P1+ P2 is less than or equal to 5ms, the first information value is 9-22, and each value corresponds to one period configuration of 2 patterns, where: when the SCS is 15k, 30k or 60k, the second message indicates available resources of P1 and P2, or 4 bits are used in the second message to indicate available resources of P1 and 4 bits are used to indicate available resources of P2.

Specifically, when 2 TDD patterns are configured (pre-configured), the periods of the two TDD patterns are P1 and P2, respectively, and P1+ P2 is less than or equal to 5 ms:

optionally, the first information value is 9 to 22, and each value corresponds to one cycle configuration when 2 patterns are provided.

For example, when the code point value 22 corresponds to 2 patterns, P1 is 1ms, and P2 is 4 ms.

(1)SCS＝15k：

the resource information Z is the high 4bit of the 8 bits used for indicating the available resource of P1, the low 4bit is used for indicating the available resource of P2, and the indication precision is 1 slot.

For example, 15k SCS, the period configuration P1 is 10ms, and 10ms P2 is 10ms, and 10 slots are available in each period, and 11 types of resources are available in each period. At this point 16 code points (0-15) are indicated by the high 4bit, with code points 0-10 indicating the available resources in P1. The 16 code points (0-15) are indicated by the low 4 bits, with code points 0-10 indicating the available resources in P2. For example, a code point 10 indicated by a high 4bit indicates that the available resource of P1 is 10 slots, and a code point 10 indicated by a low 4bit indicates that the available resource of P2 is 10 slots.

Alternatively, 8-bit joint coding indicates available resources of P1+ P2, which indicates a precision of 1 slot.

For example, SCS is 15k, the period is configured to be P1 is 10ms, P2 is 10ms, and then there are 10 slots in each period, and 11 × 11 is 121 available resources, which correspond to 0-120 of the 256 code points indicated by 8 bits, for example, code point 120 indicates that the available resource in P1 is 10 slots, and the available resource in P2 is 10 slots.

(2)SCS＝30k：

(3)SCS＝60k：

(4)SCS＝120k：

1) If 2 TDD patterns are configured, the TDD patterns have periods P1 and P2, and P1+ P2 is less than or equal to 2.5ms, the first information value is 9-14, each value corresponds to one period configuration of 2 patterns, where: when the SCS is 120k, the second message indicates available resources of P1 and P2, or 4 bits are used in the second message to indicate available resources of P1 and 4 bits are used to indicate available resources of P2.

Specifically, when the P1+ P2 is less than or equal to 2.5ms, the value of the first information is 9-14.

2) If 2 TDD patterns are configured, the TDD patterns have periods P1 and P2, P1 is 2ms, P2 is 2ms, and 2.5ms or less is P1+ P2 or less is 5ms, the first information value is 15, and each value corresponds to one period configuration when 2 patterns are configured, where: when the SCS is 120k, the second message indicates available resources of P1 and P2, or 4 bits are used in the second message to indicate available resources of P1 and 4 bits are used to indicate available resources of P2.

When 2.5ms < P1+ P2 ≦ 5 ms:

Specifically, P1 is 5ms, P2 is 5ms, and the first information takes a value of 23 to 25.

In a specific implementation, if 2 TDD patterns are configured, where a period of the TDD patterns is P1 and P2, P1 is 5ms, P2 is 5ms, and 10ms is not greater than P1+ P2, the first information value is 23 to 25, and each value or multiple value corresponds to one period configuration of 2 patterns, where: with SCS 120k, the second information indicates, of available resources P1 and P2:

only one of P1 and P2 has available resources, and the value of the first information is 23; both P1 and P2 have available resources, and the value of the first information is 24-25.

Specifically, only one of P1 and P2 has available resources, and the value of the first information is 23.

The resource information Z ═ 8bit joint coding indicates available resources, the indication precision of which is 1slot, or the indication precision of which is 2 slot.

For example, with SCS 120k, the period is configured to be P1 ═ 5ms, and P2 ═ 5ms, then there are only 40 slots in 1 period, and the total available resources are 41+41-1 ═ 81 (minus the case where both repeated periods are 0 slots), corresponding to 0-81 of 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; the code point 81 indicates that the available resource in P2 is 41 slots, and the available resource in P1 is 0 slots.

Both P1 and P2 have available resources, and the value of the first information is 24-25.

For example, SCS is 120k, the period is configured to be P1 is 5ms, P2 is 5ms, then 40 slots are total in each period, the indication precision is 2 slots, then 21 × 21-1 is the total available resources are 440, corresponding to 0-219 of 256 code points indicated by 8 bits when the first value is 24, and 0-219 of 256 code points indicated by 8 bits when the first value is 25. For example, when the first value is 25, the code point 219 indicates that the available resource in P1 is 40 slots, and the available resource in P2 is 40 slots.

Specifically, P1 is 10ms, P2 is 10ms, and the first information takes a value of 26 to 30 assuming that the number of available resources in P1 and P2 is not more than 64.

If 2 TDD patterns are configured, the period of the TDD patterns is P1 and P2, P1 is 10ms, P2 is 10ms, and P1+ P2 is not more than 10ms, the first information value is 26-30, and each value or multiple value corresponds to one period configuration when 2 patterns are configured, where: with SCS 120k, the second information indicates, of available resources P1 and P2:

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

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

It can be understood that there are available resources in both P1 and P2, and the first information takes on values of 27-30.

For example, if the available resource indication accuracies of P1 and P2 are both 2 slots, the available resource of P1+ P2 is indicated by joint coding using resource information Z ═ 8bit, and at this time, one period configuration corresponds to four code points.

And the second mode is implemented when the first information uses 5 bits to indicate the number of patterns and the period configuration of the patterns, and the second information uses 7 bits to indicate available resources.

In the method, the second information occupies Z7 bits, the first information adopts a joint coding mode, and the resource indication precision is not more than 4 slots.

Specifically, the code is jointly configured by the number of patterns and the period of the patterns, the first information indicates the number of the patterns and the period of the patterns, the first information is X + Y ═ 5 bits, values are 0-31, and the second information occupies Z ═ 7 bits and is used for indicating available resources, that is, T ═ Z + X + Y ═ 12 bits. Wherein:

the second information indicating resources indicates the number of available resources.

Further, the available resources may be uplink resources, and/or resources that meet at least a preset requirement.

Furthermore, the preset requirement means that the symbols S to S + L-1 are uplink resources.

To sum up, in the technical solution provided in the embodiment of the present invention, by designing the bit encoding manner in the parameter SL-TDD-Config: individual coding or joint coding, and indicating the mode: the joint indication or the segmented indication ensures that the parameter ensures higher indication precision as much as possible while indicating the number of the available resources, and can enable the parameter SL-TDD-Config to indicate the available resources of different TDD mode cycles under different SCSs with higher indication precision.

The following is a description by way of example.

1) Shared use of T bit by SL-TDD-Config

a) The specification is as follows: the way for the user to acquire the SL-TDD-Config includes at least one of the following ways

i. Configuration: the base station can directly configure the SL-TDD-Config to the user through SL SIB or RRC

Pre-configuration: or SL-TDD-Config can be pre-configured directly to the user in pre-configuration

Self-determination: SL-TDD-Config that the user self-infers from TDD configuration information, such as TDD-UL-DL-ConfigCommon, obtained from base station configuration or pre-configuration or PC5-RRC

Other user indications: or may be derived from received SL information, such as SL MIB or PC5-RRC, for example, UE2 received the SL MIB of UE1, where the SL MIB carries SL-TDD-Config.

b) The specification is as follows: the 'acquiring 1 or 2 TDD patterns' described in the present invention may specifically indicate 1 or 2 TDD patterns in the SL-TDD-Config that is acquired (the acquiring means is as described above: configuration, pre-configuration, self-determination, and other user indication), or may indicate 1 or 2 TDD patterns in the acquired TDD configuration information

c) Note that: the present invention can be used for at least one of the following uses

i. According to the acquired TDD configuration information, how to set the instruction content of SL-TDD-Config

How to understand the meaning indicated in SL-TDD-Config if SL-TDD-Config is acquired

2) All schemes described below (taking Z ═ 8bit as an example) can select either a 4bit +4bit segmentation indication or an 8bit joint indication, and Z ═ 7bit can be treated similarly

3) For the case of segment indication, it is understood that Z1+ Z2, Z1 and Z2 may have a plurality of permutation combinations, and in the case of Z8 bit, 4+4/3+5/5+3/2+6/6+2/1+7/7+1 may work, but the specification takes 4+4 or 4+3 as an example

Scheme 1: the Z corresponding to the resource information is 8bit, the number of patterns and the period of the patterns are jointly coded, the indication precision of the resource information is not more than 2slot, and the method has the advantages that: precision 2slot

The method comprises the steps of 1, jointly coding the number of patterns and the period of the patterns, wherein first information indicates the number of the patterns and the period of the patterns, the first information is X + Y-5 bits and takes a value of 0-31, and resource information Z-8 bits is used for indicating available resources, namely T-13 bits

A. The resource information indicates the number of available resources

B. The available resources may be uplink resources and/or resources meeting at least a predetermined requirement

i. It is preset that the symbol S to the symbol S + L-1 are uplink resources, for example, S is 2, L is 7, and if the symbol 3-11 in one slot is an uplink resource, the slot is the uplink resource

The slot does not meet the requirement; if the symbols 2-9 in a slot are uplink resources, the slot meets the requirement

C. Optionally, at this time, the indication precision of the resource information is not greater than 2 slots

D. Meaning of indicated content is related to SCS of sidelink transmission

When 1 TDD pattern is obtained, the period of the TDD pattern is P

■ optionally, the first information has values of 0-8, and each value corresponds to a period configuration of 1 pattern

e.g. code point value is 8, corresponding to 1 pattern configuration with period of 10ms

■ alternatively, the meaning of the resource information is as follows

a) SCS 15k

The resource information Z ═ 8bit indicates the available resources in the period P, and the indication precision thereof is 1slot

When the available resources are 11 cases in total, and when 0 to 10 of 256 code points are indicated by corresponding 8 bits, the number of the available resources is respectively corresponding to, for example, when the code point 10 is indicated by 8 bits, the available resources are 10 slots.

b) SCS 30k

c) When SCS is 60k

d) When SCS is 120k

The resource information Z ═ 8bit indicates the available resource in the period P, and the block with the indication precision of 1slot can be abstracted as: only one TDD pattern with period P, SCS 2^μ15kHz, if the resource information indicates a value of n,

indicating that n available resources exist in the period P;

optionally, the number of resources indicated by the resource information at this time ranges from 0 to min (2)^Z-1,P*2^μ)

Or

Indicating that there are n +1 available resources in period P

Optionally, the number of resources indicated by the resource information at this time ranges from 1 to min (2)^Z,P*2^μ)

Optionally, at this time, the indication precision of the resource information is 1slot

When 2 TDD patterns are obtained, the periods of the two TDD patterns are P1 respectively

And P2, and P1+ P2< ═ 5ms

■ optionally, the first information has values of 9-22, each value corresponding to a period configuration of 2 patterns

When the code point value is 22 and 2 patterns are correspondingly configured, P1 is 1ms, and P2 is 4 ms.

■ alternatively, the meaning of the resource information is as follows

a) SCS 15k

The resource information Z is 4 bits higher than 8 bits to indicate the available resource in the period P1, and 4 bits lower than the available resource

bit is used for indicating available resources in a period P2, and the indication precision is 1slot

e.g. 15k with scs, cycle configuration P1 10ms, and P2 10ms, then 10 slots each are provided for each cycle, and there are 11 cases of available resources for each cycle. At the moment, 16 code points (0-15) are indicated by high 4 bits, and the code points 0-10 represent available resources in P1; the 16 code points (0-15) are indicated by the low 4 bits, with code points 0-10 indicating the available resources in P2.
