Before the technical scheme of the application is introduced, the following description is made on the related knowledge of the application:

sidestream communication: sidestream communication is a direct communication between terminals. Fig. 1 shows a schematic structural diagram of a sidestream communication system according to an exemplary embodiment of the present application. The sidestream communication system includes a first terminal 110, a second terminal 120, and a network device 130.

In the sidestream communication, according to the coverage situation of the network device 130 where the terminal for performing communication is located, the sidestream communication may be classified into sidestream communication within the coverage of the network device 130, sidestream communication covered by a part of the network device 130, and sidestream communication outside the coverage of the network device 130, which are specifically described as follows:

fig. 1 (a): i.e., network device 130 covers the side-by-side communication within. In the sidestream communication of the first terminal 110 and the second terminal 120 within the coverage area of the network device 130, both the first terminal 110 and the second terminal 120 are within the coverage area corresponding to the same network device. At this time, both the first terminal 110 and the second terminal 120 may perform sidestream communication based on the same sidestream configuration by receiving the configuration signaling of the network device 130.

Fig. 1 (b): i.e., the sidestream communications covered by the portion of network device 130. The first terminal 110 is within the coverage of the network device 130, the second terminal 120 is not within the coverage of the network device 130, and a part of the terminals performing the sidestream communication are located within the coverage of the network device 130. At this time, the first terminal 110 can receive the configuration signaling of the network device 130, and perform sidestream communication according to the configuration signaling; and the second terminal 120 cannot receive the configuration signaling of the network device 130. In this case, the terminal outside the coverage area of the network device 130 (i.e., the second terminal 120) will determine the sidestream configuration according to the Pre-configuration information and the information carried in the sidestream broadcast channel (Physical Sidelink Broadcast Channel, PSBCH) sent by the terminal within the coverage area of the network device 130 (i.e., the first terminal 110), so as to perform sidestream communication.

Fig. 1 (c): i.e., network device 130 covers outside sidestream communications. The first terminal 110 and the second terminal 120 are both out of coverage of the network device 130, and the first terminal 110 and the second terminal 120 determine sidestream configuration to perform sidestream communication according to the preconfiguration information.

Terminal-to-terminal/vehicle-to-other Device (Device to Device/Vehicle to Everything, D2D/V2X):

terminal-to-terminal communication is a D2D-based side-uplink transmission technique, and has higher spectral efficiency and lower transmission delay, unlike conventional cellular systems in which communication data is received or transmitted via network devices. Taking the internet of vehicles system as an example, the internet of vehicles system adopts a terminal-to-terminal direct communication mode, and two transmission modes are defined in 3 GPP: a first mode and a second mode.

First mode: the transmission resources of the terminal are distributed by the network equipment, and the terminal transmits data on the side link according to the resources distributed by the network equipment; the network device may allocate resources for single transmission to the terminal, or may allocate resources for semi-static transmission to the terminal. As shown in fig. 1 (a), the first terminal 110 and the second terminal 120 are located within the coverage of the network device 130, and the network device 130 allocates transmission resources (i.e., sidestream transmission resources) used for sidestream transmission to the first terminal 110 and the second terminal 120.

Second mode: and the terminal selects one Resource from a Resource Pool (RP) to transmit data. As shown in fig. 1 (c), the first terminal 110 and the second terminal 120 are located outside the coverage area of the network device 130, and the first terminal 110 and the second terminal 120 may independently select transmission resources from a preconfigured resource pool to perform side transmission, respectively; or as shown in fig. 1 (a), the first terminal 110 and the second terminal 120 autonomously select transmission resources from a resource pool configured by the network device 130 for side transmission.

NR-V2X: taking the terminal as a vehicle as an example, in NR-V2X, since automatic driving needs to be supported, higher requirements are put on data interaction between vehicles, such as higher throughput, lower latency, higher reliability, larger coverage, more flexible resource allocation, etc.

In long term evolution (Long Term Evaluation, LTE), data interaction between vehicles mainly supports broadcast transmission modes, and fig. 2 shows a broadcast transmission schematic diagram in LTE, which includes, for example, a transmitting end terminal 210 and at least one receiving end terminal 220, and specifically includes the following three broadcast transmission modes:

fig. 2 (a): unicast propagation mode. For unicast transmission, the receiving terminal has only one terminal. I.e. unicast propagation, is performed between the sender terminal 210 and one receiver terminal 220.

Fig. 2 (b): multicast propagation mode. A plurality of receiving end terminals 220 form a communication group, and the transmitting end terminal 210 transmits data, and other terminals in the group are receiving end terminals.

Fig. 2 (c): broadcast propagation mode. For broadcast transmission, the receiving-end terminal 220 is any one of terminals around the transmitting-end terminal 210.

In NR-V2X, unicast and multicast transmission modes are introduced, and specific reference is made to the foregoing.

NR-V2X System frame Structure: fig. 3 shows the slot structure in NR-V2X, which is specifically explained as follows:

fig. 3 (a) shows a slot structure in which a physical sidelink feedback channel (Physical Sidelink Feedback Channel, PSFCH) channel is not included in a slot; diagram (b) in fig. 3 shows a slot structure including a PSFCH channel.

Illustratively, the physical sidelink control channel (Physical Sidelink Control Channel, PSCCH) in NR-V2X occupies 2 or 3 OFDM symbols in the time domain starting from the second sidelink symbol of the slot that is available for sidelink transmission, and may occupy {10, 12, 15, 20, 25} physical resource blocks (Physical Resource Block, PRB) in the frequency domain. To avoid blind detection of PSCCH by the terminal, only one PSCCH symbol number and PRB number are allowed to be configured in one resource pool.

In addition, because the sub-channel is the minimum granularity of resource allocation in the frequency domain of the physical side-channel shared channel (Physical Sidelink Shaerd Channel, PSSCH) in NR-V2X, the number of PRBs occupied by the PSCCH must be less than or equal to the number of PRBs contained in one sub-channel in the resource pool, so as not to cause additional limitation on PSSCH resource selection or allocation.

As shown in fig. 3 (a), the PSSCH is also exemplarily time-domain starting from the second sidelink symbol available for sidelink transmission of the slot, the last time-domain symbol in the slot being a guard interval GP symbol, and the remaining symbols being mapped to the PSSCH. The first side symbol in the slot is a repetition of the second side symbol, and typically the receiving end terminal uses the first side symbol as an automatic gain control (Automatic Gain Control, AGC) symbol, the data on which is not typically used for data demodulation. The PSSCH occupies K subchannels in the frequency domain, each comprising N consecutive PRBs.

As shown in fig. 3 (b), when a PSFCH channel is included in a slot, the penultimate and penultimate symbols in the slot are used as PSFCH channel transmissions, and one time domain symbol before the PSFCH channel is used as a GP symbol.

Second order sidestream control information (Sidelink Control Information, SCI) mechanism in NR-V2X:

The second-order SCI is introduced into NR-V2X, the first-order SCI is borne in PSCCH and used for indicating information such as transmission resource, reserved resource information, MCS level, priority and the like of PSSCH, the second-order SCI is transmitted in the resource of PSSCH, demodulation is carried out by using DMRS of PSSCH and used for indicating information such as sender ID, receiver ID, HARQ ID, NDI and the like used for data demodulation.

Fig. 4 shows a resource mapping diagram of a second order SCI. Wherein, the second order SCI starts mapping from the first demodulation reference signal (Demodulation Reference Signal, DMRS) symbol of the PSSCH, and maps in the frequency domain before the time domain. Specifically, the PSCCH occupies 3 symbols (symbols 1, 2, 3), the DMRS of the PSCCH occupies symbols 4, 11, the second order SCI is mapped starting from symbol 4, frequency division multiplexed with the DMRS on symbol 4, the second order SCI is mapped to symbols 4, 5, 6, and the size of the resources occupied by the second order SCI depends on the number of bits of the second order SCI.

Side feedback channel: in NR-V2X, a side-by-side feedback channel is introduced for improved reliability. For example, for unicast transmission, a transmitting end terminal transmits sidestream data (including PSCCH and PSSCH) to a receiving end terminal, the receiving end terminal transmits HARQ feedback information (including ACK or NACK) to the transmitting end terminal, and the transmitting end terminal determines whether retransmission is required according to the feedback information of the receiving end terminal. Wherein the HARQ feedback information is carried in a sidelink feedback channel, e.g. PSFCH.

Optionally, the sidestream feedback is activated or deactivated through pre-configuration information, network device configuration information or a transmitting terminal.

Specifically, if the sidestream feedback is activated, the receiving end terminal receives sidestream data sent by the sending end terminal, and feeds back HARQ ACK or NACK to the sending end according to the detection result, and the sending end terminal decides to send retransmission data or new data according to feedback information of the receiving end. If the sidestream feedback is deactivated, the receiving end terminal does not need to send feedback information, and the transmitting end terminal typically sends data in a blind retransmission manner, for example, the transmitting end terminal repeatedly sends K times for each sidestream data, instead of deciding whether to need to send retransmission data according to the feedback information of the receiving end terminal.

Format of sidestream feedback channel:

in NR-V2X, a PSFCH is introduced, which carries only 1 bit of HARQ-ACK information, occupies 2 time domain symbols in the time domain, and the second symbol carries side row feedback information, the data on the first symbol is a duplicate of the data on the second symbol, but the first symbol is used as AGC, and occupies 1 PRB in the frequency domain.

Fig. 5 shows a schematic diagram of a slot structure of a side-row transmission resource, in which positions of time domain symbols occupied by PSFCH, PSCCH, and PSSCH in one slot are schematically shown.

In one slot, the last symbol is used as GP; the penultimate symbol is used for PSFCH transmission; the data of the third last symbol is the same as the data of the PSFCH symbol and is used as AGC; the fourth last symbol also serves as GP; the first symbol in the slot is used as AGC and the data on that symbol is the same as the data on the second time domain symbol in the slot; the PSCCH occupies 3 time domain symbols; the remaining symbols may be used for PSSCH transmission.

Resources of the sidelink feedback channel:

to reduce the overhead of the PSFCH channel, one slot defined in every N slots includes the PSFCH transmission resource, i.e. the period of the side-by-side feedback resource is N slots, where n=1, 2, 4, the parameter N is preconfigured or network device configured. Illustratively, the transmission of sidelink transmission resources is as shown in fig. 6 when n=4.

Wherein, the PSSCH transmitted in slots 2, 3, 4, 5 is transmitted in slot 7, so that slots {2, 3, 4, 5} can be regarded as a set of slots, and the PSSCH transmitted in the set of slots has its corresponding PSFCH in the same slot.

In addition, the resources of the sidelink feedback channel can be determined according to the time slot to which the PSSCH belongs and the starting position of the occupied sub-band. When n=4, fig. 7 shows a schematic diagram of correspondence of sidelink transmission resources. Wherein, PSSCH transmitted in the same sub-band starting position in different time slots respectively correspond to different PSFCH resources in the feedback time slot.

Resource pool (ResourcePool, RP):

a resource pool is a collection of resources. The resource pool of the sidelink is a collection of time-frequency resources for the sidelink transmission. The resource pool of the side-link may be configured by pre-configuration information or network configuration information.

Specifically, the transmitting terminal transmits the PSCCH/PSSCH in a transmission resource pool configured for the transmitting terminal, the receiving terminal detects whether the PSCCH/PSSCH transmitted by other terminals exists in a receiving resource pool configured for the receiving terminal, and if so, the receiving terminal determines transmission resources for transmitting the PSFCH according to the transmission resources of the PSCCH/PSSCH and configuration information of the PSFCH in the receiving resource pool.

After the transmitting terminal transmits the PSCCH/PSSCH, the transmitting terminal determines the resources for receiving the PSFCH according to the PSFCH configuration information in the transmitting resource pool, and detects the PSFCH. In order for the transmitting end terminal and the receiving end terminal to perform data transmission normally, the transmission resource pool configured for the transmitting end terminal is generally made the same as the reception resource pool configured for the receiving end terminal. Therefore, the sending terminal and the receiving terminal can determine the same PSFCH transmission resource according to the PSSCH transmission resource and the configuration information of the PSFCH in the respective resource pools.

Minislot (mini-slot) transmission:

in the Rel-15NR Uu port transmission system, micro-slot transmission or scheduling is introduced, i.e. a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) or a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) scheduled by a network device does not use a slot as granularity, but uses a time domain symbol in the slot as granularity, so that the purpose of reducing time delay can be achieved.

Fig. 8 shows a scheduling diagram of micro slots. The physical downlink control channel (Physical Downlink Control Channel, PDCCH) located at the head of the timeslot can schedule the PDSCH located in the same timeslot (with the minislot 1 as a resource unit) or schedule the PUSCH located at the tail of the timeslot (with the minislot 2 as a resource unit), so that uplink and downlink data can be rapidly scheduled in one timeslot.

In an NR system, micro-slot scheduling with {2,4,7} time domain symbols as time domain scheduling granularity is supported.

Fig. 9 is a flowchart illustrating a method for determining a sidelink transmission resource according to an exemplary embodiment of the present application.

The embodiment of the application is exemplified by the application of the method described above to the sidestream communication system shown in fig. 1, wherein the sidestream communication system comprises a terminal and a network device, and the method is applied to the terminal. The method for determining the sidestream transmission resources provided by the embodiment of the application comprises the following steps:

Step 102: and the terminal receives the configuration signaling sent by the network equipment.

Configuration signaling may also be referred to as scheduling signaling. Optionally, the configuration signaling is radio resource control (Radio Resource Control, RRC) signaling or downlink control information (Downlink Control Information, DCI).

Illustratively, configuration signaling is used to determine the time domain location of one or more sidelink transmission resources.

Illustratively, the sidelink transmission resource is used for sidelink transmission based on the micro time slot; or, the side transmission resource is a transmission resource taking the micro time slot as the scheduling granularity; alternatively, the sidelink transmission resource is for sidelink minislot transmission.

The side transmission resource is used for transmitting at least one of the following: PSCCH, PSSCH, PSFCH.

Illustratively, the configuration signaling carries configuration information related to the micro time slot to which the configuration side transmission resource belongs, including but not limited to at least one of the following information:

configuration information for determining the first minislot interval.

The first minislot interval is used for indicating the number of minislots of intervals between the minislots to which the first sidestream transmission resource belongs and the minislots to which the configuration signaling belongs, or for indicating the number of minislots of intervals between the minislots to which the first sidestream transmission resource belongs and the reference system frame number (SystemFrameNumber, SFN). Illustratively, the first minislot interval is used to determine a first time domain location of the first sidelink transmission resource, the first time domain location being determined based on the time domain location at which the configuration signaling is received and the first minislot interval.

Configuration information for determining the second minislot interval.

The second minislot interval is used for indicating the number of minislots of the interval between the minislot to which the mth sidestream transmission resource belongs and the minislot to which the first sidestream transmission resource belongs. Illustratively, the second minislot space is used to determine a minislot to which the mth sidestream transmission resource belongs, and the minislot to which the mth sidestream transmission resource belongs is determined based on the time domain position of the first sidestream transmission resource and the second minislot space. Wherein m is an integer greater than 1.

Location information of the first sidelink transmission resource on the associated slot.

Illustratively, the location information of the first sideline transmission resource on the timeslot to which the first sideline transmission resource belongs is used to determine, in the timeslot to which the first sideline transmission resource belongs, the ith minislot to which the first sideline transmission resource belongs in the timeslot.

Wherein a minislot comprises one or more time domain symbols within a slot, and a plurality of minislots may be included within a slot. Specifically, the number of micro time slots in one time slot can be set according to actual needs, and the present application is not limited herein. Optionally, one time slot includes 2 minislots, and the time domain position of the first sidestream transmission resource is indicated as the first (or second) minislot in the time slot by the indication information in the configuration signaling.

Optionally, the configuration signaling includes first signaling including, but not limited to, at least one of the following information: configuration information for determining a first minislot interval, configuration information for determining a second minislot interval, and location information of a first sidelink transmission resource on an associated slot.

For example, taking the configuration signaling as DCI as an example, the terminal receives DCI sent by the network device, where a time interval domain of the DCI carries an index value of a first minislot interval, where the index value is used to determine the number of minislots of intervals between a minislot to which a first sidelink transmission resource belongs and a minislot to which the DCI belongs; meanwhile, the DCI also carries first indication information, where the first indication information is used to indicate a second minislot interval, where the terminal may determine a minislot to which other sidestream transmission resources except for the first sidestream transmission resource belong, and the minislots to which other sidestream transmission resources except for the first sidestream transmission resource belong are determined according to the minislot to which the first sidestream transmission resource belongs and the second minislot interval.

For another example, one time slot includes two micro time slots, the terminal receives DCI sent by the network device, and the time interval domain of the DCI carries an index value of a time slot interval, where the index value is used to determine the number of time slots of the interval between the time slot to which the first sidelink transmission resource belongs and the time slot to which the DCI belongs; meanwhile, the DCI also carries indication information, where the indication information is used to indicate that the first sideline transmission resource corresponds to the 2 nd minislot in the belonged timeslots.

Step 104: and the terminal determines the time domain position of the sidestream transmission resource according to the configuration signaling.

Wherein a minislot comprises one or more time domain symbols within a slot, and a plurality of minislots may be included within a slot. For example, one slot includes two minislots. Specifically, the number of micro time slots in one time slot can be set according to actual needs, and the present application is not limited herein.

According to the foregoing, the sidestream transmission resource is used to transmit at least one of: PSCCH, PSSCH, PSFCH; the configuration signaling carries information related to the micro time slot to which the configuration side transmission resource belongs, including but not limited to at least one of the following information: configuration information for determining a first micro-slot interval, configuration information for determining a second micro-slot interval, and position information of a first sidelink transmission resource on an affiliated slot. The first micro time slot interval refers to the number of micro time slots of the interval between the micro time slot to which the first side line transmission resource belongs and the micro time slot to which the configuration signaling belongs, or the micro time slot interval between the micro time slot to which the first side line transmission resource belongs and the reference SFN; the second minislot interval refers to the number of minislots of intervals between the minislots to which the other sidestream transmission resources except the first sidestream transmission resource belong and the minislots to which the first sidestream transmission resource belongs.

Taking the configuration signaling as an example, the DCI is configured, where a time interval domain of the DCI carries a first index value of a first minislot interval, where the first index value is used to determine the number of minislots of intervals between a minislot to which a first sidelink transmission resource belongs and a minislot to which the DCI belongs. After receiving the DCI transmitted by the network device, the terminal may uniquely determine a time domain position of the first sidelink transmission resource according to the micro-slot to which the DCI belongs and the interval number corresponding to the first index value, where the time domain position corresponds to one micro-slot.

Illustratively, the determination of the Time domain location of the first sidelink transmission resource may be determined by a Time interval (Time gap) field in the configuration signaling.

The time interval is used for determining a time slot interval between the first sidestream transmission resource and a time slot or a micro time slot where the configuration signaling is located, and the time domain position of the first sidestream transmission resource can be determined according to the information and the time domain position where the terminal receives the configuration signaling. The first sidelink transmission resource may be in a time slot or in a micro time slot.

Optionally, taking DCI as an example of configuration signaling, the network device configures a table of time intervals by using a parameter sl-DCI-ToSL-Trans, where an element in the table represents the number of slots or minislots, and the parameter in DCI is an index value, and according to the index value and the time table, a specific time interval size can be determined.

Specifically, after receiving the DCI, the terminal determines the size of a specific time interval according to the parameters sl-DCI-ToSL-Trans and the time interval table, and then determines the time domain position of the first sidelink transmission resource according to the time domain position of the DCI and the size of the time interval.

Optionally, the determination of the time domain position of the first sidelink transmission resource may also be determined by a time interval (sl-TimeOffsetCG-Type 1) field in the configuration signaling.

The time interval is used for determining the time interval between the first sidelink transmission resource and the reference SFN (sl-TimeReference SFN-Type 1), and the parameter is expressed as the number of micro time slots. The time domain location of the first sidelink transmission resource may be determined based on the information and the time domain location of the reference SFN.

In the sidestream transmission resources allocated by the network device for the terminal, more than one sidestream transmission resource can be allocated, and the time domain position of each sidestream transmission resource needs to be determined. After determining the time domain position of the first sidelink transmission resource, the terminal may determine the time domain position of the remaining sidelink transmission resource according to the time domain position of the first sidelink transmission resource and the second micro-slot interval. It should be understood that, when the side transmission resources allocated by the network device to the terminal include N side transmission resources, the second minislot interval includes N-1 minislot intervals, which respectively correspond to the minislot intervals between the first side transmission resource and N-1 other side transmission resources except the first side transmission resource.

Illustratively, the time domain location of the other sidelink transmission resources than the first sidelink transmission resource may be determined by a time domain resource allocation (Time resource assignment) domain in the configuration signaling.

The time domain resource allocation is used for indicating the time domain resource in the same manner as the SCI format 1-A, and the value of the parameter is expressed by a time domain resource indication value (Time Resource Indication Value, TRIV) and is used for determining the time slot interval or micro time slot interval of other N-1 side line transmission resources except the first side line transmission resource relative to the first side line transmission resource. The application takes as an example that the micro time slot interval of other N-1 side line transmission resources except the first side line transmission resource relative to the first side line transmission resource is determined by TRIV.

And according to the time domain position of the first transmission resource determined by the content, combining the information to determine the time domain positions of the remaining N-1 transmission resources.

Illustratively, the relationship between the value of TRIV and the number N of sidelink transmission resources allocated by the network device is as follows:

if n=1: triv=0;

if n=2: triv=t ₁ ；

If n=3:

when (t) ₂ -t ₁ -1) at 15 or less: triv=30 (t ₂ -t ₁ -1)+t ₁ +31；

Otherwise: triv=30 (t ₂ -t ₁ -1)+t ₁ +31；

Wherein t is ₂ 、t ₁ The time interval of the second transmission resource and the third transmission resource relative to the first transmission resource is expressed by the number of micro time slots, and when N=2, 1 is less than or equal to t ₁ Less than or equal to 31; when n=3, 1.ltoreq.t ₁ ≤30，t_1<t ₂ ≤31。

Taking N as 3 as an example, by combining the two information and the time slot to which the configuration signaling belongs, the time domain positions of N (n=1, 2, or 3) sidelink transmission resources allocated by the network device to the terminal can be determined.

Illustratively, taking the example that the configuration signaling is DCI, fig. 10 shows a schematic diagram of a slot interval of a sidelink transmission resource. Wherein, the DCI allocates 3 sideline transmission resources and allocates the transmission resources of the PUCCH, specifically as follows:

a represents the time interval between the micro time slot (i.e. micro time slot n) to which the bearing DCI belongs and the first side transmission resource, and is determined by the time interval domain in the DCI;

t ₁ representing the micro time slot interval between the allocated second side transmission resource and the first side transmission resource, and determining according to the time domain resource allocation domain in the DCI;

t ₂ representing the micro-slot spacing between the allocated third sideline transmission resource relative to the first sideline transmission resource, and is determined according to the time domain resource allocation domain in the DCI.

For another example, still taking the configuration signaling as DCI, the DCI carries indication information a and indication information B, where the indication information a is used to indicate a time interval between a first sideline transmission resource and a timeslot where the DCI is located, and the timeslot where the first sideline transmission resource belongs may be determined according to the indication information a and the timeslot location where the DCI is located, and the indication information B is used to indicate a minislot location of the first sideline transmission resource on the timeslot where the first sideline transmission resource belongs. After receiving the DCI transmitted by the network device, the terminal may determine, according to the timeslot to which the sidelink transmission resource belongs and the indication information B, a time domain position of the sidelink transmission resource, where the time domain position corresponds to a minislot.

In summary, in the method for determining the sidelink transmission resources provided by the embodiment of the application, by taking the micro time slot as granularity, the terminal determines the time domain position corresponding to the sidelink transmission resources according to the configuration signaling, so that the transmission scheduling with the micro time slot granularity is realized in the sidelink communication scene, and the transmission delay is reduced.

Fig. 11 is a flowchart illustrating a method for transmitting sidelink transmission resources according to an exemplary embodiment of the present application.

The embodiment of the application is exemplified by the application of the method described above to the sidestream communication system shown in fig. 1, wherein the sidestream communication system comprises a terminal and a network device, and the method is applied to the network device. The method for transmitting the sidestream transmission resources provided by the embodiment of the application comprises the following steps:

step 202: the network device sends configuration signaling to the terminal.

According to the foregoing, the sidestream transmission resource is used to transmit at least one of: PSCCH, PSSCH, PSFCH; the configuration signaling carries information related to the micro time slot to which the configuration side transmission resource belongs, including but not limited to at least one of the following information: configuration information for determining a first micro-slot interval, configuration information for determining a second micro-slot interval, and position information of a first sidelink transmission resource on an affiliated slot.

Configuration signaling may also be referred to as scheduling signaling.

Optionally, the configuration signaling is DCI, and is used to determine that the configuration information of the first micro slot interval is carried in a time interval domain of the DCI, and is used to determine that the configuration information of the second micro slot interval is carried in a time domain resource allocation domain of the DCI.

Optionally, the configuration signaling is RRC signaling.

Step 204: the terminal receives the configuration signaling.

According to the foregoing, the terminal may obtain at least one of the following information according to the received configuration signaling: configuration information for determining a first micro-slot interval, configuration information for determining a second micro-slot interval, and position information of a first sidelink transmission resource on an affiliated slot.

For example, taking the configuration signaling as DCI, where the network device sends DCI to the terminal, and the time interval domain of the DCI carries an index value of a first minislot interval, where the index value is used to determine the number of minislots of the first minislot to which the first sidelink transmission resource belongs and the minislot to which the DCI belongs; meanwhile, the DCI also carries first indication information, where the first indication information is used to indicate a second minislot interval, where the terminal may determine a minislot to which other sidestream transmission resources except for the first sidestream transmission resource belong, and the minislots to which other sidestream transmission resources except for the first sidestream transmission resource belong are determined according to the minislot to which the first sidestream transmission resource belongs and the second minislot interval.

For another example, one time slot includes two micro time slots, the terminal receives DCI sent by the network device, and the time interval domain of the DCI carries an index value of a time slot interval, where the index value is used to determine the number of micro time slots of the interval between the time slot to which the first sidelink transmission resource belongs and the time slot to which the DCI belongs; meanwhile, the DCI also carries indication information, where the indication information is used to indicate that the first sideline transmission resource corresponds to the 2 nd minislot in the belonged timeslots.

In summary, in the method for transmitting the sidelink transmission resources provided by the embodiment of the application, by transmitting the configuration signaling, the terminal can determine the time domain position corresponding to the sidelink transmission resources with the micro-slot granularity, thereby realizing the transmission scheduling with the micro-slot granularity in the sidelink communication scene and reducing the transmission delay.

Fig. 12 is a flowchart illustrating a transmission method of a sidelink transmission resource according to an exemplary embodiment of the present application. The embodiment of the present application is illustrated by applying the transmission method of the sidestream transmission resource to the sidestream communication system shown in fig. 1, where the sidestream communication system includes a terminal and a network device, and taking configuration signaling including a first signaling as an example, the transmission method of the sidestream transmission resource provided by the embodiment of the present application includes the following steps:

Step 301: the network device sends a second signaling to the terminal.

Illustratively, the second signaling is used to configure the set of minislot intervals. Wherein the set of minislot intervals includes at least one candidate minislot interval.

Optionally, the second signaling is RRC signaling, and the set of minislot intervals is carried in the parameter sl-DCI-ToSL-Trans.

Step 302: the terminal receives the second signaling.

After receiving the second signaling, the terminal may acquire the set of minislot intervals.

Illustratively, taking the example that the second signaling is RRC signaling, the network device sends the RRC signaling to the terminal, where the signaling includes a parameter sl-DCI-ToSL-Trans. Wherein the parameter sl-DCI-ToSL-trans= {1,2,4,6,8, 12, 16, 32}.

The terminal may obtain the set of minislot intervals {1,2,4,6,8, 12, 16, 32} after receiving the second signaling. Wherein the set of minislot intervals includes eight candidate minislot intervals.

Specifically, the first candidate micro-slot interval refers to 1 micro-slot in the number of the micro-slots to which the first side transmission resource belongs and the micro-slots to which the first signaling belongs, the second candidate micro-slot interval refers to 2 micro-slots in the number of the micro-slots to which the first side transmission resource belongs, the third candidate micro-slot interval refers to 4 micro-slots in the number of the micro-slots to which the first side transmission resource belongs and the micro-slots to which the first signaling belongs, the fourth candidate micro-slot interval refers to 6 micro-slots in the number of the micro-slots to which the first side transmission resource belongs and the micro-slots to which the first signaling belongs, the fifth candidate micro-slot interval refers to 8 micro-slots in the number of the micro-slots to which the first side transmission resource belongs and the micro-slots to which the first side transmission resource belongs, the sixth candidate micro-slot interval refers to 12 micro-slots in the number of the micro-slots to which the first side transmission resource belongs and the micro-slots to which the first signaling belongs, and the fifth candidate micro-slot interval refers to the first side transmission resource belongs to 16 micro-slots in the number of the micro-slots to which the first side transmission resource belongs and the micro-slots to which the first side transmission resource belongs.

Illustratively, steps 301 and 302 are optional steps. That is, in the transmission process of the sidelink transmission resource, the second signaling may be received before the present transmission or may be received during the present transmission.

Step 303: the network device sends a first signaling to the terminal.

Illustratively, the first signaling carries information about the first minislot interval.

Wherein the information related to the first micro-slot interval is used to determine the first micro-slot interval.

The first minislot interval is used for indicating the number of minislots of intervals between the minislots to which the first sidestream transmission resource belongs and the minislots to which the configuration signaling belongs. For example, taking the configuration signaling including the first signaling as an example, the first minislot interval is 3, the first sidestream transmission resource belongs to the minislot and the first signaling belongs to the minislot, and the first minislot interval is 3 minislots.

Optionally, the information about the first micro-slot interval includes a first index value of the first micro-slot interval. Wherein the first index value is used to determine a first minislot interval in the set of minislot intervals.

Illustratively, the value j of the first index value is used to indicate that the first minislot interval is the j-th minislot interval in the set of minislot intervals.

Based on this, the terminal determines a number of minislots of intervals between the minislots to which the first sidelink transmission resource belongs and the minislots to which the first signaling belongs, the number of intervals being determined according to the first index value.

Illustratively, the first signaling carries a minislot spacing indication information, and a time domain position of the first sidestream transmission resource can be determined according to the minislot spacing indication information. For example, the minislot interval indication information is used to indicate the number of minislots that are spaced between the time domain location of the first sidelink transmission resource and the time domain location of the reference SFN.

Step 304: the terminal receives the first signaling.

When the first signaling carries the first index value of the first micro time slot interval, the terminal can acquire the first index value after receiving the first signaling.

The related information of the first micro time slot interval includes a first index value of the first micro time slot interval, the first index value is 3, for example, the network device sends a first signaling to the terminal, the first index value carried in the first signaling is 3, and after receiving the first signaling, the terminal can determine that the first index value is 3 according to the first signaling.

Illustratively, the first signaling is a configuration signaling sent by the network device to the terminal.

Optionally, the first signaling is DCI, and the first index value is carried in a Time interval (Time gap) field of the DCI.

Taking the first signaling as DCI, the first index value carried in the time interval domain of the DCI is 2 (assuming that the index value starts from 0), the number of intervals including 5 minislots in the minislot interval set is exemplified, and the number of intervals of 5 minislots is 1, 2, 4, 6, 8, respectively.

The micro time slot interval set comprises five candidate micro time slot intervals, wherein the first candidate micro time slot interval refers to the 1 micro time slot interval between the micro time slot to which the first side line transmission resource belongs and the micro time slot to which the first signaling belongs, the second candidate micro time slot interval refers to the 2 micro time slots interval between the micro time slot to which the first side line transmission resource belongs and the micro time slot to which the first signaling belongs, and the third candidate micro time slot interval refers to the 4 micro time slots interval between the micro time slot to which the first side line transmission resource belongs and the micro time slot to which the first signaling belongs.

After receiving the DCI, the terminal may obtain the first index value of 2, and since the index value starts from 0, the index value of 2 is the third index value in the corresponding index value sequence number. According to the first index value, the terminal determines that the interval number of the corresponding micro time slots in the micro time slot interval set is 4. And the terminal determines that the micro time slot to which the first sidestream transmission resource belongs is different from the micro time slot to which the first signaling belongs by 4 micro time slots in the micro time slot interval set according to the first index value.

The minislot interval set may be obtained according to step 301 and step 302, or may be obtained before the transmission of the current sidelink transmission resource.

Step 305: and the terminal determines the first micro time slot interval according to the related information of the first micro time slot interval.

According to the foregoing, the related information of the first micro slot interval may optionally include a first index value of the first micro slot interval, based on which the terminal may determine the first micro slot interval. The following takes the example that the related information of the first micro slot interval includes a first index value of the first micro slot interval.

Based on this, step 305 is optionally implemented as follows:

and the terminal determines the first time slot interval in the micro time slot interval set according to the related information of the first micro time slot interval.

Illustratively, a first minislot interval is used to determine a first time domain location of a first sidelink transmission resource, the first minislot interval being an i-th candidate of the set of minislot intervals, i being determined based on a first index value.

According to step 301 and step 302, the terminal may obtain a set of minislot intervals; according to step 303 and step 304, the terminal may obtain the first index value. Based on this, the terminal may determine a first micro-slot interval from the first index value in the set of micro-slot intervals.

Taking the example that the first index value is 2 (assuming that the index value starts from 0), the set of minislot intervals is {1,2,4,6,8}, the terminal is determining that the first minislot interval is the third candidate minislot interval in the set of minislot intervals based on the first index value. I.e. the first micro slot interval is 4.

Step 306: the terminal determines a first time domain location of a first sidelink transmission resource.

Illustratively, the first time domain position is determined based on a second time domain position and the first minislot interval, the second time domain position being a time domain position at which the first signaling is received, or the second time domain position being a time domain position corresponding to the reference SFN.

It should be understood that when the second time domain position is a time domain position corresponding to the reference SFN, the terminal may determine a first micro-slot interval according to the first signaling sent by the network device, and further determine a first time domain position corresponding to the first sidelink transmission resource according to the time domain position of the reference SFN and the first micro-slot interval.

Wherein the time interval indicated by the first signaling is based on a minislot granularity.

Specifically, after determining the first minislot interval, the terminal may determine a first time domain location of the first sidelink transmission resource according to the first minislot interval.

Taking n as a first micro time slot interval as an example, the embodiment of the application provides two optional ways of determining the first time domain position as follows:

determination mode 1: the first time domain position is a time domain position separated by n minislots after the second time domain position.

Referring to fig. 13, one slot includes two minislots, and the terminal receives a first signaling sent by the network device in minislot 3, where the first signaling is carried in the PDCCH. I.e. the first signaling is on minislot 3.

Taking the first index value as 2 (assuming the index value starts from 0), the set of minislot intervals is {1,2,4,6,8, 12, 16, 32}, for example. According to the foregoing, after receiving the first index value, the terminal may determine that the first minislot interval is 4, that is, n=4, in the minislot interval set according to the first index value.

From the minislot 3 and the first minislot interval, the terminal may determine a first time domain location. Specifically, the time domain position of the micro time slot 3 after the interval of 4 micro time slots is the micro time slot to which the first sidestream transmission resource belongs. That is, it can be determined that the first time domain position is the minislot 7 according to the determination mode 1.

Determination mode 2: the first time domain position is a time domain position separated by n logical minislots after the second time domain position.

Illustratively, the first signaling further carries a first resource pool index, where the first resource pool index is used to indicate a first target resource pool, and the logical minislots belong to minislots in the first target resource pool, and the first time domain position belongs to the first target resource pool.

The resource pool refers to a resource set formed by schedulable resources of the terminal, and the resource pool defines a time-frequency resource range of side communication.

Referring to fig. 14, one slot includes two minislots, and the terminal receives a first signaling sent by the network device in minislot 3, where the first signaling is carried in the PDCCH.

In addition, the network device is configured with two resource pools, namely a resource pool 1 and a resource pool 2, wherein the resource pool 1 comprises micro time slots with even indexes, the resource pool 2 comprises micro time slots with odd indexes, and the micro time slots 3 belong to the micro time slots in the resource pool 2.

Also taking the first index value as 2 (assuming the index value starts from 0), the set of minislot intervals is {1,2,4,6,8, 12, 16, 32}, for example. According to the foregoing, after receiving the first index value, the terminal may determine that the first minislot interval is 4, that is, n=4, in the minislot interval set according to the first index value.

Meanwhile, the first signaling also carries a first resource pool index, and according to the first resource pool index, the terminal can determine that the first target resource pool is the resource pool 2. According to the foregoing, the logical minislots are those belonging to resource pool 2.

Based on this, according to the first resource pool index, the minislot 3 and the first minislot interval, the terminal can determine the first time domain position, specifically, since the first target resource pool is the resource pool 2, the minislot 3 is the minislot to which the first sidelink transmission resource belongs at the time domain position of 4 logic minislots. That is, it can be determined that the first time domain position is the minislot 11 according to the determination mode 2.

Step 307: the terminal determines the time domain position of the mth side transmission resource.

The first signaling also carries first indication information, where the first indication information is used to indicate the second micro time slot interval, and the time domain position of the mth sidelink transmission resource is determined based on the first time domain position and the second micro time slot interval. Alternatively, the first signaling is DCI or RRC, and the second minislot interval is carried in a time domain resource allocation domain of DCI or RRC, which may be denoted by TRIV.

The second micro time slot interval is used for indicating the number of micro time slots of the interval between the micro time slot to which the m-th side line transmission resource belongs and the micro time slot to which the first side line transmission resource belongs, that is, is used for indicating the micro time slot interval of the m-th side line transmission resource relative to the first side line transmission resource, and m is an integer greater than 1.

In determining the time domain position of the first sidelink transmission resource, the terminal needs to determine the time domain position of the remaining sidelink transmission resource. In step 307, the time domain position of the mth side row transmission resource is determined by the second minislot interval. The second minislot interval is represented by TRIV as an example, and the relation between TRIV and the number of sidelink transmission resources may refer to the relation given in the foregoing, or may be set according to actual needs, which is not limited herein.

Taking the example that the number of the side transmission resources is 3, after determining the time domain position of the first side transmission resource, the method can be based on t ₁ And t ₂ Time domain locations of the second and third sidelink transmission resources are determined. Wherein t is ₁ Representing the minislot spacing, t, between the second sidelink transmission resource relative to the first sidelink transmission resource ₂ Representing the minislot spacing between the third sidelink transmission resource relative to the first sidelink transmission resource.

Optionally, in the case that the first signaling further carries the first resource pool index, the time domain position of the mth sidelink transmission resource is a time domain position separated by p logical minislots after the first time domain position. The first resource pool index is used for indicating a first target resource pool, p is a second micro time slot interval, the logic micro time slot belongs to the micro time slot in the first target resource pool, the first time domain position belongs to the first target resource pool, and p is an integer not less than 0.

Illustratively, in the embodiment of the present application, the step on the terminal side may be separately an embodiment of a method for determining a sidelink transmission resource, and the step on the network device side may be separately an embodiment of a method for transmitting a sidelink transmission resource.

In summary, according to the method for determining and the method for sending the sidestream transmission resource provided by the embodiments of the present application, the related information of the first minislot interval is carried in the first signaling, so that the terminal can determine the first minislot interval, thereby determining the minislot to which the first sidestream transmission resource belongs; and meanwhile, the terminal determines the micro time slot of the remaining sidestream transmission resource according to the micro time slot of the first sidestream transmission resource. Optionally, the related information of the first micro-slot interval includes a first index value of the first micro-slot interval, and the terminal determines the first micro-slot interval in the micro-slot interval set according to the index value, so as to determine the micro-slot to which the first sidelink transmission resource belongs.

Fig. 15 is a flowchart illustrating a transmission method of another sidelink transmission resource according to an exemplary embodiment of the present application.

The embodiment of the present application is illustrated by applying the transmission method of the sidestream transmission resource to the sidestream communication system shown in fig. 1, where the sidestream communication system includes a terminal and a network device, and taking configuration signaling including a first signaling as an example, the transmission method of the sidestream transmission resource provided by the embodiment of the present application includes the following steps:

step 401: the network device sends a first signaling to the terminal.

Illustratively, the first signaling carries the second indication information and the third indication information.

The second indication information is used for determining a first time slot to which the first sidestream transmission resource belongs, and the third indication information is used for determining an i-th micro time slot of the first sidestream transmission resource in the first time slot, wherein i is an integer not less than 0.

Wherein the first time slot comprises at least one minislot.

Step 402: the terminal receives the first signaling.

When the first signaling carries the second indication information and the third indication information, the terminal can acquire the second indication information and the third indication information after receiving the first signaling.

Specifically, the terminal may determine, according to the second indication information, a time slot to which the first sidelink transmission resource belongs; then, the terminal can determine the micro-time slot position of the first sidestream transmission resource in the belonged time slot according to the third indication information.

Illustratively, the second indication information is used for indicating the number of time slots of the interval between the time slot to which the first sidelink transmission resource belongs and the time slot to which the first signaling belongs.

Illustratively, the second indication information is used to indicate a time interval between a time slot to which the first sidelink transmission resource belongs and the reference SFN.

Taking the first signaling as DCI as an example, the terminal receives DCI sent by the network device, where a time interval domain of the DCI carries second indication information, where the second indication information includes a second index value of a first slot interval, where the second index value is used to determine a number of slots between a slot to which a first sidelink transmission resource belongs and a slot to which the DCI belongs.

In addition, the third indication information is used for indicating the micro-time slot position of the first sidelink transmission resource in the time slot to which the first sidelink transmission resource belongs.

Optionally, the third indication information includes an N-bit information field, where the N-bit information field is used to indicate a micro-slot position in the slot. Wherein the value of N depends on the maximum number of minislots included in one slot. For example, one slot includes two minislots, and then n=1; as another example, if one slot includes four minislots, n=2. In the case that two minislots are included in one slot, the first signaling includes a 1-bit information field, which is used to indicate the first minislot in the slot when the information field is valued at 0, and is used to indicate the second minislot in the slot when the information field is valued at 1.

Step 403: and the terminal determines a first time slot to which the first sidestream transmission resource belongs according to the second indication information.

According to the foregoing, the second indication information is used to indicate the number of slots of the interval between the slot to which the first sidelink transmission resource belongs and the slot to which the first signaling belongs.

Based on the above, after receiving the first signaling, the terminal may acquire the second indication information, and determine, according to the second indication information, a slot position corresponding to the first sidelink transmission resource.

Optionally, the second indication information includes related information of the first time slot interval, where the related information is used to determine the first time slot of the first sidelink transmission resource. For example, the second index information includes a second index value of the first slot interval, and the terminal determines the first slot according to the index value.

Taking the first signaling as an example of DCI, a time interval domain of the DCI carries a second index value of a first slot interval, where the second index value is used to determine the number of slots of the interval between a slot to which a first sidelink transmission resource belongs and a slot to which the DCI belongs. After receiving the DCI transmitted by the network device, the terminal may uniquely determine, according to the timeslot to which the DCI belongs and the number of intervals corresponding to the first index value, the timeslot to which the first sidelink transmission resource belongs, where the timeslot is the first timeslot.

Step 404: and the terminal determines the ith micro time slot of the first sidestream transmission resource in the first time slot according to the third indication information.

According to the foregoing, the third indication information is used to indicate the micro-slot position of the first sidelink transmission resource in the slot to which the first sidelink transmission resource belongs.

Based on the above, after receiving the first signaling, the terminal may acquire the third indication information, and determine, according to the third indication information, that the first sidelink transmission resource is in the i-th minislot of the first slot terminal.

Specifically, taking the case that the first timeslot includes at least two minislots as an example, the terminal may determine, according to the third indication information, a minislot position of the first sidestream transmission resource in the at least two minislots. For example, the third indication information is used to indicate that the first sidelink transmission resource corresponds to the 2 nd minislot in the belonging time slot.

Step 405: the terminal determines the micro time slot to which the mth side transmission resource belongs.

The first signaling also carries fourth indication information, where the fourth indication information is used to indicate the second micro time slot interval, and the micro time slot to which the mth side transmission resource belongs is determined based on the time domain position of the first side transmission resource and the second micro time slot interval. Where m is an integer greater than 1, and the time domain position of the first sidelink transmission resource is a minislot position.

Alternatively, the first signaling is DCI or RRC, and the second minislot interval is carried in a time domain resource allocation domain of DCI or RRC, which may be denoted by TRIV.

The second micro time slot interval is used for indicating the micro time slot interval of the mth side line transmission resource relative to the first side line transmission resource, and m is an integer greater than 1.

In the sidestream transmission resources allocated by the network device for the terminal, more than one sidestream transmission resource can be allocated, and the time domain position of each sidestream transmission resource needs to be determined. After determining the micro time slot to which the first sidestream transmission resource belongs, the micro time slot to which the remaining sidestream transmission resource belongs needs to be determined.

In step 405, the terminal may determine, through the second minislot interval, a minislot to which the mth sidestream transmission resource belongs, where m is an integer greater than 1. It should be understood that, when the side transmission resources allocated by the network device to the terminal include N side transmission resources, the second minislot interval includes N-1 minislot intervals, which respectively correspond to the minislot intervals between the first side transmission resource and N-1 other side transmission resources except the first side transmission resource. The relation between TRVI and the number of sidelink transmission resources is represented by TRIV as an example by the second minislot interval, and may be set according to the above-mentioned relation, or according to actual needs, the present application is not limited herein.

Taking the example that the number of the sidestream transmission resources is 3, after determining the micro time slot to which the first sidestream transmission resource belongs, it can be according to t ₁ And t ₂ Determining the micro time slot to which the second and third sidestream transmission resources belong. Wherein t is ₁ Representing the minislot spacing, t, between the second sidelink transmission resource relative to the first sidelink transmission resource ₂ Representing the minislot spacing between the third sidelink transmission resource relative to the first sidelink transmission resource.

Optionally, in the case that the first signaling further carries the second resource pool index, the minislots to which the mth sideline transmission resource belongs are time domain positions separated by r logical minislots after the time domain position of the first sideline transmission resource, and m is an integer greater than 1. The second resource pool index is used for indicating a second target resource pool, r is a second micro time slot interval, the logic micro time slot belongs to the micro time slot in the second target resource pool, and the time domain position of the first sidestream transmission resource belongs to the second target resource pool.

In summary, according to the method for determining and the method for sending the sidestream transmission resource provided by the embodiments of the present application, the terminal can determine the minislot to which the first sidestream transmission resource belongs according to the second indication information and the third indication information through the second indication information and the third indication information carried in the first signaling; and meanwhile, the terminal determines the micro time slot of the remaining sidestream transmission resource according to the micro time slot of the first sidestream transmission resource.

Fig. 16 is a flowchart illustrating a transmission method of another sidelink transmission resource according to an exemplary embodiment of the present application. The embodiment of the present application is illustrated by applying the transmission method of the sidestream transmission resource to the sidestream communication system shown in fig. 1, where the sidestream communication system includes a terminal and a network device, and taking configuration signaling including a first signaling as an example, the transmission method of the sidestream transmission resource provided by the embodiment of the present application includes the following steps:

step 501: the network device sends a second signaling to the terminal.

Illustratively, the second signaling is used to configure the set of slot intervals.

Optionally, the second signaling is RRC signaling, and the set of slot intervals is carried in the parameter sl-DCI-ToSL-Trans.

Step 502: the terminal receives the second signaling.

The terminal may acquire the set of slot intervals after receiving the second signaling.

The terminal may obtain a set of slot intervals {1,2,4,6,8, 12, 16, 32} after receiving the second signaling. Wherein the set of slot intervals includes eight candidate slot intervals.

Illustratively, steps 501 and 502 are optional steps. That is, in the transmission process of the sidelink transmission resource, the second signaling may be received before the present transmission or may be received during the present transmission.

Step 503: the network device sends a first signaling to the terminal.

Illustratively, the first signaling carries the second indication information and the third indication information. Wherein the second indication information includes information related to the first slot interval.

The related information of the first time slot interval is used for determining the first time slot interval, so that the terminal can determine the first time slot to which the first sidestream transmission resource belongs.

According to the foregoing, the second indication information is used for determining a first timeslot to which the first sideline transmission resource belongs, and the third indication information is used for determining an i-th minislot of the first sideline transmission resource in the first timeslot, where i is an integer not less than 0. The second indication information is used for indicating the number of time slots of the interval between the time slot to which the first sidestream transmission resource belongs and the time slot to which the first signaling belongs, or the second indication information is used for indicating the time interval between the time slot to which the first sidestream transmission resource belongs and the reference SFN; the third indication information is used for indicating the micro-time slot position of the first sidestream transmission resource in the belonged time slot.

Illustratively, the first slot interval is used to indicate the number of slots of the interval between the first slot to which the first sidelink transmission resource belongs and the slot to which the configuration signaling belongs. For example, if the first slot interval is 4, the first slot is separated from the slot to which the first signaling belongs by 4 slots.

Optionally, the information about the first slot interval includes a second index value of the first slot interval. Wherein the second index value is used to determine the first slot interval in the set of slot intervals.

Illustratively, the value k of the second index value is used to indicate that the first slot interval is the kth slot interval in the set of slot intervals.

Based on this, the terminal can determine the number of slots of the interval between the slot to which the first sidelink transmission resource belongs and the slot to which the first signaling belongs, the number of intervals being determined according to the second index value.

Illustratively, the second index value is used to determine a first slot interval in a set of slot intervals, the set of slot intervals including at least one candidate slot interval. Illustratively, the terminal determines, in the set of time slot intervals, the number of time slots of the interval between the time slot to which the first sidelink transmission resource belongs and the time slot to which the first signaling belongs according to the second index value.

Step 504: the terminal receives the first signaling.

Because the first signaling carries the second index value of the first time slot interval, the terminal can acquire the second index value after receiving the first signaling.

Taking the case that the related information of the first time slot interval includes a second index value of the first time slot interval, the second index value is 3 as an example, the network device sends the first signaling to the terminal, the second index value carried in the first signaling is 3, and the terminal can determine that the second index value is 3 according to the first signaling after receiving the first signaling.

Optionally, the first signaling is DCI, and the second index value is carried in a time interval field of the DCI.

Taking the first signaling as DCI, the second index value carried in the time interval domain of the DCI is 2 (assuming that the index value starts from 0), the number of intervals including 5 slots in the slot interval set is 1, 2, 4, 6, 8, respectively.

The time slot interval set includes five candidate time slot intervals, the first candidate time slot interval refers to the interval number of the time slot to which the first side transmission resource belongs and the time slot to which the first signaling belongs is 1 time slot, the second candidate time slot interval refers to the interval number of the time slot to which the first side transmission resource belongs and the time slot to which the first signaling belongs is 2 time slots, and the third candidate time slot interval refers to the interval number of the time slot to which the first side transmission resource belongs and the time slot to which the first signaling belongs is 4 time slots.

After receiving the DCI, the terminal may obtain the second index value of 2, and since the index value starts from 0, the index value 2 is the third index value in the corresponding index value sequence number. According to the second index value, the terminal determines that the interval number of the corresponding time slots in the time slot interval set is 4. And the terminal determines that the time slot of the first sidestream transmission resource is different from the time slot of the first signaling by 4 time slots in the time slot interval set according to the second index value.

The set of slot intervals may be obtained according to step 501 and step 502, or may be obtained before the transmission of the current sidelink transmission resource.

Step 505: and the terminal determines the first time slot interval according to the related information of the first time slot interval.

According to the foregoing, the related information of the first slot interval may optionally include a second index value of the first slot interval, based on which the terminal may determine the first slot interval. The following takes the example that the related information of the first slot interval includes the second index value of the first slot interval.

Based on this, step 505 is optionally implemented as follows:

and the terminal determines the first time slot interval in the time slot interval set according to the related information of the first time slot interval.

Illustratively, the first slot interval is used to determine a first slot to which the first sidelink transmission resource belongs, where the first slot interval is an i-th candidate slot interval in the slot interval set, and i is determined according to the second index value.

According to step 501 and step 502, the terminal may obtain a second index value; the terminal may obtain a set of slot intervals according to steps 503 and 504. Based on this, the terminal may determine the first slot interval from the set of slot intervals according to the second index value.

Taking the example that the second index value is 2 (assuming that the index value starts from 0), the slot interval set is {1,2,4,6,8}, the terminal determines that the first slot interval is the slot interval of the third candidate among the slot interval set according to the second index value. I.e. the first slot interval is 4.

Step 506: the terminal determines a first time slot to which the first sidelink transmission resource belongs.

Illustratively, the first time slot is determined based on a second time domain location and a first time slot interval, the second time domain location being a time domain location at which the first signaling is received, or the second time domain location being a time domain location corresponding to the reference SFN.

It should be understood that when the second time domain position is a time domain position corresponding to the reference SFN, the terminal may determine a first time slot interval according to the first signaling sent by the network device, and further determine a time domain position corresponding to the first sidelink transmission resource according to the time domain position of the reference SFN and the first time slot interval.

Wherein the time interval indicated by the first signaling is based on a slot granularity.

Specifically, after determining the first slot interval, the terminal may determine, according to the first slot interval, a first slot to which the first sidelink transmission resource belongs.

Taking q as a first slot interval as an example, the embodiment of the present application provides two alternative determination manners as follows:

determination mode 1: the first time slot is a time domain position separated by q time slots after the second time domain position.

That is, the terminal may determine the first slot according to the slot to which the first signaling belongs and the first slot interval.

For example, the terminal receives the first signaling sent by the network device in time slot 3, i.e. the first signaling is on time slot 3.

Taking the second index value as 2 (assuming the index value starts from 0), the set of slot intervals is {1,2,4,6,8}, for example. According to the foregoing, after receiving the second index value, the terminal may determine that the first slot interval is 4, that is, q=4, in the slot interval set according to the second index value. From slot 3 and the first slot interval, the terminal may determine the first slot.

Specifically, according to the determining mode 1, it may be determined that the time domain position of the time slot 3 after the interval of 4 time slots is the first time slot to which the first sidelink transmission resource belongs.

Determination mode 2: the first time slot is a time domain position separated by q logical time slots after the second time domain position.

Illustratively, the first signaling further carries a second resource pool index, where the second resource pool index is used to indicate a second target resource pool, and the logical time slot belongs to a time slot in the second target resource pool, and the first time slot belongs to the second target resource pool.

For example, the terminal receives a first signaling sent by the network device in a time slot 3, where the network device configures two resource pools for the terminal, namely a resource pool 1 and a resource pool 2, where the resource pool 1 includes even-indexed time slots, the resource pool 2 includes odd-indexed micro time slots, and the time slot 3 belongs to the time slot in the resource pool 2.

Also taking the example that the second index value is 2 (assuming that the index value starts from 0), the set of slot intervals is {1,2,4,6,8 }. According to the foregoing, after receiving the second index value, the terminal may determine that the first slot interval is 4, that is, n=4, in the slot interval set according to the second index value.

Meanwhile, the first signaling also carries a second resource pool index, and according to the second resource pool index, the terminal can determine that the second target resource pool is the resource pool 2. According to the foregoing, the logical time slot is a time slot belonging to resource pool 2.

Based on this, according to the second resource pool index, the time slot 3 and the first time slot interval, the terminal may determine the first time slot, specifically, according to the determining mode 2, it may be determined that, because the second target resource pool is the resource pool 2, the micro time slot 3 is at the time domain position of 4 logical time slots, that is, the first time slot to which the first sidelink transmission resource belongs.

Step 507: and the terminal determines the ith micro time slot of the first sidestream transmission resource in the first time slot according to the third indication information.

Specifically, taking the example that the first timeslot includes at least two micro timeslots, the terminal may determine, according to the third indication information, a specific micro timeslot position of the first sidelink transmission resource in the at least two micro timeslots. For example, the third indication information is used to indicate that the first sidelink transmission resource corresponds to the 2 nd minislot in the belonging time slot.

Step 508: the terminal determines the micro time slot to which the mth side transmission resource belongs.

The first signaling also carries fourth indication information, where the fourth indication information is used to indicate the second micro time slot interval, the micro time slot to which the mth side transmission resource belongs is determined based on the time domain position of the first side transmission resource and the second micro time slot interval, and m is an integer greater than 1. Alternatively, the first signaling is DCI or RRC, and the second minislot interval is carried in a time domain resource allocation domain of the DCI or RRC, which may be denoted as TRVI.

Illustratively, step 508 is identical to step 405 and is not described in detail.

In summary, according to the method for determining and the method for sending the sidestream transmission resource provided by the embodiments of the present application, the second indication information carries the related information of the first time slot interval, so that the terminal can determine the first time slot interval, thereby determining the time slot to which the first sidestream transmission resource belongs, and then the terminal determines the micro time slot position of the first sidestream transmission resource in the time slot to which the first sidestream transmission resource belongs through the third indication information; and meanwhile, the terminal determines the micro time slot of the remaining sidestream transmission resource according to the micro time slot of the first sidestream transmission resource. Optionally, the related information of the first slot interval includes a second index value of the first slot interval, and the terminal determines the first slot interval in the slot interval set according to the index value, so as to determine a slot to which the first sidelink transmission resource belongs.
