Fig. 1 to fig. 4 are system frameworks from a vehicle-mounted terminal to a vehicle-mounted terminal according to an embodiment of the present application.

As shown in fig. 1, in the network coverage inside line communication, all terminals performing side line communication (including the terminal 1 and the terminal 2) are in the coverage of the same network device, so that all terminals can perform side line communication based on the same side line configuration by receiving configuration signaling of the network device.

As shown in fig. 2, in the case of partial network coverage sidestream communication, a part of the terminal performing sidestream communication is located within the coverage of the network device, and this part of the terminal (i.e., the terminal 1) can receive the configuration signaling of the network device, and perform sidestream communication according to the configuration of the network device. And the terminal outside the network coverage (i.e. terminal 2) cannot receive the configuration signaling of the network device, in this case, the terminal outside the network coverage determines the sidestream configuration according to the pre-configuration information and the information carried in the sidestream broadcast channel PSBCH sent by the terminal located in the network coverage, so as to perform sidestream communication.

As shown in fig. 3, for network coverage outside line communication, all terminals performing outside line communication (including terminal 1 and terminal 2) are located outside the network coverage, and all terminals determine the outside line configuration according to the pre-configuration information to perform the outside line communication.

Device-to-device communication is a D2D-based side-link (SL) transmission technique, and thus has higher spectral efficiency and lower transmission delay, unlike conventional cellular systems in which communication data is received or transmitted by network devices. 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, the terminal is located in the coverage area of the network, and the network allocates transmission resources for side transmission to the terminal.

Second mode:

and the terminal selects one resource from the resource pool to transmit data. As shown in fig. 3, the terminal is located outside the coverage area of the cell, and autonomously selects transmission resources in a pre-configured resource pool to perform side transmission; or in fig. 1, the terminal autonomously selects transmission resources from a resource pool configured by the network to perform side transmission.

The second mode resource selection is performed according to the following two steps:

step 1:

and the terminal takes all available resources in the resource selection window as a resource set A.

If the terminal transmits data in some time slots in the listening window and does not listen, all resources on the corresponding time slots in the selection window are eliminated. The terminal determines the corresponding time slot in the selection window by using the value set of the 'resource reservation period' domain in the used resource pool configuration.

If the terminal detects PSCCH in the interception window, measuring RSRP of the PSCCH or RSRP of PSSCH scheduled by the PSCCH, and if the measured RSRP is larger than SL-RSRP threshold value and determining that reserved resources are in the resource selection window according to the resource reservation information in the side-row control information transmitted in the PSCCH, excluding corresponding resources from the set A. And if the residual resources in the resource set A are insufficient, the resource set A carries out X% of all the resources before the resource elimination, raising the SL-RSRP threshold by 3dB, and re-executing the step 1. The possible value of X is {20,35,50}, and the terminal determines the parameter X from the value set according to the priority of the data to be sent. Meanwhile, the SL-RSRP threshold is related to the priority carried in the PSCCH that the terminal listens to and the priority of the data to be sent by the terminal. And the terminal takes the residual resources after the resource exclusion in the set A as candidate resource sets.

Step 2:

the terminal randomly selects a plurality of resources from the candidate resource set as the sending resources of the initial transmission and retransmission of the terminal.

In NR-V2X, automatic driving needs to be supported, and thus, higher demands are placed on data interaction between vehicles, such as higher throughput, lower latency, higher reliability, larger coverage, more flexible resource allocation, etc.

In LTE-V2X, a broadcast transmission scheme is supported, and in NR-V2X, unicast and multicast transmission schemes are introduced. For unicast transmission, the receiving terminal has only one terminal. Fig. 4 is a schematic diagram of unicast transmission provided in an embodiment of the present application. As shown in fig. 4, unicast transmission is performed between the terminals 1 and 2. For multicast transmission, the receiving end is all terminals in a communication group or all terminals in a certain transmission distance. Fig. 5 is a schematic diagram of multicast transmission according to an embodiment of the present application. As shown in fig. 5, the terminals 1, 2, 3 and 4 constitute a communication group in which the terminal 1 transmits data, and the other terminal devices in the group are all receiving-end terminals. For the broadcast transmission scheme, the receiving end is any one of the terminals around the transmitting end terminal. Fig. 5 is a schematic diagram of broadcast transmission according to an embodiment of the present application. As shown in fig. 6, the terminal 1 is a transmitting terminal, and the other terminals around it, the terminals 2 to 6 are receiving terminals.

The slot structure in NR-V2X is described below with reference to FIGS. 7 and 8.

Fig. 7 is an example of a slot structure provided by an embodiment of the present application that does not include a PSFCH channel; fig. 8 is an example of a slot structure including a PSFCH channel provided by an embodiment of the present application.

As shown in fig. 7 or 8, PSCCH in NR-V2X occupies 2 or 3 OFDM symbols from the second sidelink symbol of the slot in the time domain, and may occupy {10,12, 15,20,25} PRBs in the frequency domain. To avoid blind detection of PSCCH by the UE, only one PSCCH symbol number and PRB number is allowed to be configured in one resource pool. In addition, because the sub-channel is the minimum granularity of PSSCH resource allocation 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. The PSSCH also starts in the time domain from the second sidelink symbol of the slot, the last time domain symbol in the slot being the guard interval GP symbol, the remaining symbols mapping 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 AGC (automatic gain control ) 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. 7, the PSFCH channel may not be included in the slot.

As shown in fig. 8, 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.

2-order SCI is introduced into NR-V2X, the first-order SCI is carried 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 sent in the resource of PSSCH and is demodulated by using DMRS of PSSCH and used for indicating information such as source ID, target ID, HARQ ID, NDI and the like used for data demodulation. The second order SCI starts mapping from the first DMRS symbol of the PSSCH, frequency domain first and then time domain mapping. Fig. 9 is a schematic diagram of PSCCH and PSSCH frame structures provided in an embodiment of the present application, where, as shown in fig. 9, PSCCH occupies 3 symbols (symbols 1, 2, 3), DMRS of PSSCH occupies symbols 4, 11, second order SCI is mapped from symbol 4, and is frequency division multiplexed with DMRS on symbol 4, second order SCI is mapped to symbols 4, 5, 6, and the size of resources occupied by second order SCI depends on the number of bits of second order SCI.

In NR-V2X, a side-by-side feedback channel is introduced for improved reliability.

As shown in fig. 10, for unicast transmission, a transmitting end terminal transmits side line 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.

In some embodiments, the transmitting terminal may activate or deactivate the sidestream feedback through the SCI, if the sidestream feedback is activated, the receiving terminal receives sidestream data sent by the transmitting terminal, and feeds back HARQ ACK or NACK to the transmitting terminal according to the detection result, and the transmitting terminal decides to send retransmission data or new data according to feedback information of the receiving terminal; 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.

In NR-V2X, a physical sidelink feedback channel (Physical Sidelink Feedback Channel, PSFCH) is introduced, which carries only 1 bit of HARQ-ACK information, occupies 2 time domain symbols in the time domain (the second symbol carries sidelink feedback information, the data on the first symbol is a duplicate of the data on the second symbol, but the symbol is used as AGC), and occupies 1 PRB in the frequency domain.

As shown in fig. 11, one slot may include time domain symbols occupied by PSFCH, PSCCH, and PSSCH. Specifically, in one slot, the last symbol is used as GP, the second last symbol is used for PSFCH transmission, the third last symbol is the same as the data of the PSFCH symbol, used as AGC, the fourth last symbol is also used as GP, the first symbol in the slot is used as AGC, the data on the symbol is the same as the data on the second time domain symbol in the slot, PSCCH occupies 3 time domain symbols, and the remaining symbols are available for PSSCH transmission.

In some embodiments, to reduce the overhead of the PSFCH channel, one of every N slots is defined to include the PSFCH transmission resource, i.e., the period of the sidelink feedback resource is N slots, where n=1, 2, 4, and the parameter N is preconfigured or network configured.

As shown in fig. 12, assuming that n=4, one slot of every 4 slots includes the PSFCH transmission resource, i.e., the period of the side feedback resource is 4 slots. 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 some embodiments, the PSFCH resource may be determined based on the time slot in which the PSSCH is located and the starting location of the occupied sub-band.

As shown in fig. 13, assuming that n=4, PSSCHs transmitted in the same subband start position in different slots correspond to different PSFCH resources in the feedback slot, respectively. For example, the PSSCH transmitted in the upper left corner may correspond to PSFCH resource 4 in the feedback slot.

In some embodiments, the transmission resources of the PSCCH/PSSCH, as well as the transmission resources of the PSFCH, are included in the resource pool configuration information. As an example, the resource pool configuration information may be implemented as the following information element (information element):

The method comprises the steps that a transmitting terminal TX UE transmits PSCCH/PSSCH in a transmitting resource pool configured for the transmitting terminal TX UE, a receiving terminal detects whether PSCCH/PSSCH transmitted by other terminals exists in a receiving resource pool configured for the receiving terminal TX UE, and if so, the receiving terminal determines transmission resources for transmitting PSFCH according to transmission resources of the PSCCH/PSSCH and configuration information of PSFCH in the receiving resource pool; after the transmitting end transmits the PSCCH/PSSCH, the transmitting end determines the resources of the received PSFCH according to the PSFCH configuration information in the transmitting resource pool, and detects the PSFCH. In order to enable the transmitting end and the receiving end to perform data transmission normally, a transmission resource pool configured for the transmitting end terminal is generally the same as a reception resource pool configured for the receiving end terminal. Therefore, the sending end and the receiving end 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.

In the Rel-15NR Uu port transmission system, micro-slot (mini-slot) transmission or scheduling is introduced, namely, the PUSCH or PDSCH scheduled by the network does not take time slots as granularity, but takes time domain symbols in the time slots as granularity, thereby achieving the purpose of reducing time delay.

Fig. 14 is a schematic diagram of providing a correspondence between slots and minislots (mini-slots) in an NR Uu port transmission system according to an embodiment of the present application.

As shown in fig. 14, the PDCCH at the head of the slot may schedule the PDSCH in the same slot (with the minislot 1 as a resource unit) or schedule the PUSCH at the tail of the slot (with the minislot 2 as a resource unit), so that uplink and downlink data may be rapidly scheduled in one slot.

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

In an NR SL system, the sidelink transmission or scheduling is performed with a granularity of time slots, but when the NR is applied to an industrial internet or other scenario with a high time delay requirement, the time delay of the system is more required, so that a sidelink transmission mode based on micro time slots is a feasible transmission scheme to be considered, but how to support the transmission of micro time slots on a sidelink link is a problem to be solved. The embodiment of the application provides a wireless communication method, terminal equipment and network equipment, which can reduce the time delay of sidestream transmission and further improve user experience.

Fig. 15 is a schematic flow chart of a wireless communication method 100 provided by an embodiment of the present application, where the method 100 may be performed by a terminal device. The terminal device may be a transmitting end that is about to transmit data, or may be a terminal that is about to receive data or a terminal around the transmitting end. For example, the terminal device may be the terminal B referred to above, and the terminal device may be the terminal a referred to above.

As shown in fig. 15, the method 100 may include some or all of the following:

s110, acquiring resource pool configuration information, wherein the resource pool configuration information comprises information for determining the time domain resource position of at least one micro time slot in one time slot;

s120, carrying out micro time slot side transmission based on the time domain resource position of the at least one micro time slot.

By introducing the micro time slot for side transmission and configuring the time domain resource position of at least one micro time slot in one time slot by utilizing the resource pool configuration information, the side transmission of the micro time slot is further performed based on the time domain resource position of the at least one micro time slot, namely the side transmission is performed by taking the time domain symbol in the time slot as granularity, the time delay of the side transmission can be reduced, and the user experience can be further improved.

It should be noted that, the resource pool configuration information may be configured or preconfigured by a network, and the resource pool configuration information may be pre-stored in the terminal device, which is not limited in particular by the present application. In some implementations, the "pre-configuration" may be implemented by pre-storing corresponding codes, tables, or other manners in which related information may be indicated in devices (including, for example, terminal devices and network devices), and the present application is not limited to a specific implementation thereof. Such as pre-configured, may refer to what is defined in the protocol. Alternatively, the "protocol" may refer to a standard protocol in the communication field, and may include, for example, an LTE protocol, an NR protocol, and related protocols applied to a future communication system, which is not particularly limited by the present application.

In some embodiments, the resource pool configuration information includes first indication information, where the first indication information is used to indicate a position of a starting time domain symbol occupied by each of the at least one minislot in one slot and/or is used to indicate a number of time domain symbols occupied by each of the at least one minislot in one slot.

Alternatively, the at least one micro-slot may be one micro-slot or a plurality of micro-slots.

In other words, one slot may include one micro slot, or may include a plurality of micro slots. Optionally, if one slot in the resource pool includes a plurality of minislots, the positions of the starting time domain symbols and the number of occupied time domain symbols of the plurality of minislots are respectively indicated in the resource pool configuration information.

Optionally, the first indication information is used for indicating a position of a starting time domain symbol occupied by each micro slot in one slot and is used for indicating the number of time domain symbols occupied by each micro slot in one slot.

In this embodiment, the position of the starting time domain symbol occupied by each micro slot in one slot and the number of the time domain symbols occupied by each micro slot in one slot are used to indicate the number of the time domain symbols occupied by each micro slot in one slot, so that the time domain position and the length of each micro slot transmission in one slot can be determined.

Alternatively, the first indication information may include one or more indication information.

Alternatively, the first indication information may be carried in the same or different configuration information, or the plurality of indication information may be carried in the same or different configuration information. For example, the position of the start time domain symbol and the number of time domain symbols may be in different configuration information, such as information including the position of the start time domain symbol in the resource pool configuration information, information including the number of time domain symbols in configuration information of a side Bandwidth Part (BWP), and information including the position of the start time domain symbol in configuration information of the side BWP, and information including the number of time domain symbols in the resource pool configuration information.

It should be noted that, in the embodiment of the present application, the term "indication" may be a direct indication, an indirect indication, or an indication having an association relationship. For example, a indicates B, which may mean that a indicates B directly, e.g., B may be obtained by a; it may also indicate that a indicates B indirectly, e.g. a indicates C, B may be obtained by C; it may also be indicated that there is an association between a and B.

In one implementation, the first indication information includes a first parameter and a second parameter for each of the at least one minislot; wherein the first parameter is used for indicating the position of a starting time domain symbol occupied by the micro time slot in one time slot, and the second parameter is used for indicating the number of time domain symbols occupied by the micro time slot in one time slot.

Optionally, the number of elements in the first parameter or the number of elements in the second parameter is used to indicate the number of micro slots included in one slot. For a resource pool, the number of elements in the first parameter or the number of elements in the second parameter is used to indicate the number of micro slots included in one slot in one resource pool.

That is, the present embodiment is applicable to a case where one or more minislots are included in one slot in the resource pool.

Alternatively, the second indication information may be the second parameter described above.

Optionally, for each bit in the first bit map, if the value of the bit is a first value, the time domain symbol corresponding to the bit is indicated to be the starting time domain symbol of one micro slot in the at least one micro slot, and if the value of the bit is a second value, the time domain symbol corresponding to the bit is indicated to be not the starting time domain symbol of the micro slot in the at least one micro slot. For example, the first value may be 1 and the second value may be 0. For another example, the first value may be 0 and the second value may be 1.

Optionally, in a normal Cyclic Prefix (CP) case, 14 time domain symbols are included in one slot, and the first bit bitmap may indicate a position of a start time domain symbol occupied by each of the at least one micro slot in one slot by 14 bits. In the case of the extended CP, 12 time domain symbols are included in one slot, and the first bit map may indicate a position of a start time domain symbol occupied in one slot by each of the at least one micro slot through 12 bits.

In some embodiments, the at least one micro-slot includes only one micro-slot, and the resource pool configuration information includes a second bit map for indicating time domain symbols occupied by the one micro-slot within one slot.

In other words, the position of the start time domain symbol of the one micro slot and the number of time domain symbols occupied by the one micro slot may be indicated simultaneously by the second bit map. That is, the present embodiment is applicable to a case where only one micro slot is included in one slot in the resource pool.

Optionally, for each bit in the second bit map, if the value of the bit is a first value, the time domain symbol corresponding to the bit is indicated to be the time domain symbol in the one micro slot, and if the value of the bit is a second value, the time domain symbol corresponding to the bit is indicated to be not the time domain symbol in the one micro slot. For example, the first value may be 1 and the second value may be 0. For another example, the first value may be 0 and the second value may be 1.

Alternatively, in the normal CP case, 14 time domain symbols are included in one slot, and the second bit map may indicate the time domain symbols occupied by the one micro slot in one slot by 14 bits. In the case of the extended CP, 12 time domain symbols are included in one slot, and the second bit map may indicate the time domain symbols occupied by the one micro slot in one slot by 12 bits.

In some embodiments, the resource pool configuration information further includes third indication information, where the third indication information is used to indicate an available time slot of the resource pool.

Alternatively, the available time slots may refer to time slots allocated to the resource pool.

Alternatively, the available time slots may refer to time slots included in the resource pool.

Alternatively, the available time slots may refer to time slots belonging to the resource pool.

Optionally, the third indication information is a third bit bitmap, and for each bit in the third bit bitmap, if the value of the bit is a first value, the time slot corresponding to the bit is indicated to be an available time slot of the resource pool, and if the value of the bit is a second value, the time slot corresponding to the bit is indicated to be not an available time slot of the resource pool.

In other words, the resource pool configuration information further includes indication information for indicating the available time slots of the resource pool, and the indication information for indicating the available time slots of the resource pool may be implemented in the form of a bit map. Combining the indication information for indicating the available time slots of the resource pool and the information for determining the time domain resource position of at least one micro time slot in one time slot in the embodiment, the time domain resource of the micro time slot in the resource pool can be determined.

In some embodiments, for each of the at least one minislot, the number of time domain symbols occupied by the minislot in one slot comprises: a time domain symbol occupied by a physical sidelink shared channel (Physical Sidelink Shared Channel, PSSCH), a time domain symbol occupied by a physical sidelink feedback channel (Physical Sidelink Feedback Channel, PSFCH), and a guard interval (GP) symbol.

Optionally, the number of time domain symbols occupied by the minislot in one slot may further include: symbols occupied by physical sidelink control channels (Physical Sidelink Control Channel, PSCCH).

Alternatively, the GP symbol may be the next symbol of the last time domain symbol where the PSSCH is located.

In some embodiments, for each of the at least one minislot, if the number of time domain symbols occupied by the minislot in one slot is less than or equal to a third value, the number of time domain symbols occupied by the minislot in one slot includes only the time domain symbols occupied by the PSSCH and the GP symbols.

In some embodiments, for each of the at least one minislot, if the number of time domain symbols occupied by the minislot in one slot is less than or equal to a third value, PSFCH transmission resources are not configured in the resource pool.

It should be noted that, the third value may be preconfigured or configured by a network device, which is not limited in particular in the embodiment of the present application. In some implementations, the "pre-configuration" may be implemented by pre-storing corresponding codes, tables, or other manners in which related information may be indicated in devices (including, for example, terminal devices and network devices), and the present application is not limited to a specific implementation thereof. Such as pre-configured, may refer to what is defined in the protocol. Alternatively, the "protocol" may refer to a standard protocol in the communication field, and may include, for example, an LTE protocol, an NR protocol, and related protocols applied to a future communication system, which is not particularly limited by the present application.

In some embodiments, for each of the at least one minislot, the minimum value of the number of time domain symbols occupied by the minislot in one slot is N, N is an integer greater than 1, and the index of the starting time domain symbol occupied by the minislot in one slot ranges from 0 to M-N, M representing the total number of time domain symbols included in one slot.

In other words, the minimum value of the number of time domain symbols occupied by the minislot in one slot is N, where N is an integer greater than 1, for example, n=4; the starting time domain symbol index occupied by the minislot in one slot is {0,1,2, …, M-N }, where M represents the total number of time domain symbols included in one slot, such as m=14.

The micro-slot structure in one slot to which the present application relates is exemplarily described below. An example in which one slot includes 14 OFDM symbols (corresponding to the case of a normal Cyclic Prefix (CP)) is described.

In some embodiments, the resource pool configuration information further includes fourth indication information, where the fourth indication information is used to indicate a time domain transmission resource at a micro slot level in the resource pool.

Alternatively, the resource pool may include both time domain transmission resources at a slot level and time domain transmission resources at a micro slot level.

Optionally, the time domain transmission resources in the resource pool are all time domain transmission resources at the micro time slot level.

Optionally, the resource pool configuration information may include the fourth indication information, which is used to indicate the time domain transmission resources of the micro slot level in the resource pool. Further, the resource pool configuration information may further include the first indication information, or the resource pool configuration information may further include the first bit bitmap and the second indication information, so as to indicate that the micro slot occupies a time domain symbol in the time domain transmission resource at the micro slot level.

Optionally, the fourth indication information is a fourth bit bitmap, for each bit in the fourth bit bitmap, if the value of the bit is a first value, the time slot corresponding to the bit is indicated to be a time domain transmission resource of a micro time slot level, and if the value of the bit is a second value, the time slot corresponding to the bit is indicated to be a time domain transmission resource of a time slot level. For example, the first value may be 1 and the second value may be 0. For another example, the first value may be 0 and the second value may be 1.

Optionally, one bit in the fourth bit map corresponds to one available time slot of the resource pool.

Optionally, one bit in the fourth bit map corresponds to one slot in the time domain.

In other words, the fourth bit bitmap may directly indicate the time domain transmission resources of the minislot class according to the time domain sequence, or may indicate the time domain transmission resources of the minislot class according to the time domain sequence in the available time slots in the resource pool, which is not specifically limited in the present application.

In some embodiments, the resource pool configuration information further includes fifth indication information, where the fifth indication information is used to indicate time domain resources of the physical sidelink feedback channel PSFCH.

When PSFCH transmission resources are configured in a resource pool, after receiving PSCCH and/or PSSCH sent by a sending end, a receiving end determines time domain resources of PSFCH, namely, sends the PSFCH on the determined time domain resources of PSFCH; therefore, the receiving end can send side feedback information to the sending end. Optionally, the time domain resource of the PSFCH represents a time domain symbol used for transmitting the PSFCH in one slot.

In one implementation, the fifth indication information includes a third parameter for indicating a period of time domain resources of the PSFCH and/or a fourth parameter for indicating a minimum time interval between physical sidelink shared channels PSSCHs associated with the PSFCH. For example, the fifth indication information includes a third parameter and a fourth parameter.

Optionally, the third parameter is expressed as the number of micro time slots, and/or the fourth parameter is expressed as the number of micro time slots.

Alternatively, the number of minislots may also be referred to as a logical minislot number. Wherein the logical minislots represent the minislots in the resource pool.

Optionally, the third parameter is expressed as the number of time slots, and/or the fourth parameter is expressed as the number of time slots.

Alternatively, the third parameter may also be referred to as a side-link PSFCH Period parameter (sl-PSFCH-Period).

Alternatively, the fourth parameter may also be referred to as a side-uplink PSFCH minimum time interval parameter (sl-MinTimeGapPSFCH).

As an example, the third parameter and the fourth parameter may be implemented as the following information elements:

wherein sl-MinTimeGapPSFCH is the fourth parameter; sl-PSFCH-Period is the third parameter;

in an NR SL system, time domain symbol information available for sidelink transmission in a slot is configured in a SL BWP, after determining a time domain symbol available for sidelink transmission in the slot, if PSFCH transmission resources are configured in the slot, the second last and third symbols in the time domain symbols available for sidelink transmission are used for PSFCH transmission, and the last symbol and the fourth last symbol are GP symbols, as shown in fig. 8, that is, the time domain resources of PSFCH in one slot are fixed. But when micro-slot transmission is supported, the PSFCH transmission resources in the slots may be different and configurable, as described above for case 2 through case 8. Therefore, when the resource pool is configured with transmission resources at the micro-slot level, the transmission resources of the PSFCH need to be configured correspondingly, and in particular, the positions of time domain symbols occupied by the PSFCH in one slot need to be configured.

In one implementation, the fifth indication information includes information indicating a position of a time domain symbol occupied by the PSFCH in one slot.

Optionally, the fifth indication information includes information indicating an index of a starting time domain symbol occupied by the PSFCH in one slot.

In other words, for each available time slot in the resource pool, time domain resources for transmitting the PSFCH may be determined based on the fifth indication information.

In this embodiment, when the side uplink supports the micro-slot transmission, the time-frequency resource of the micro-slot and the transmission resource of the PSFCH corresponding to the resource pool may be configured through the resource pool configuration information, so that the side uplink micro-slot transmission may be supported.

In one implementation, the fifth indication information includes a fifth parameter, where the fifth parameter is used to indicate a position of a starting time domain symbol occupied by the PSFCH in one slot.

Optionally, the fifth parameter is used to indicate an index of a starting time domain symbol occupied by the PSFCH in one slot.

In other words, the starting time domain symbol position of the PSFCH in a slot may be configured by an index (e.g., symbol index # 0-symbol index 13) indicating the starting time domain symbol that the PSFCH occupies in a slot.

Alternatively, the fifth parameter may also be referred to as a side-uplink PSFCH start symbol parameter (sl-PSFCH-StartSymbol).

Illustratively, assuming sl-PSFCH-startsymbol=11, it means that the starting symbol position of the PSFCH is symbol #11 in the slot, and the time domain symbols occupied by the PSFCH are symbol #11 and symbol #12, as in case 3/5/6 above. Assuming sl-PSFCH-startsymbol=4, it indicates that the starting symbol position of the PSFCH is symbol #4 in the slot, and the time domain symbols occupied by the PSFCH are symbol #4 and symbol #5, as in case 2/4 above. Assuming sl-PSFCH-startsymbol=6, it indicates that the starting symbol position of the PSFCH is symbol #6 in the slot, and the time domain symbols occupied by the PSFCH are symbol #6 and symbol #7, as in case 7 above. Assuming sl-PSFCH-startsymbol=5, it indicates that the starting symbol position of the PSFCH is symbol #5 in the slot, and the time domain symbols occupied by the PSFCH are symbol #5 and symbol #6, as in case 8 above.

Optionally, the fifth indication information includes a fifth bit map, for each bit in the fifth bit map, if the value of the bit is a first value, the time domain symbol corresponding to the bit is indicated to be a starting time domain symbol occupied by the PSFCH in one time slot, and if the value of the bit is a second value, the time domain symbol corresponding to the bit is indicated to be not the starting time domain symbol occupied by the PSFCH in one time slot. For example, the first value may be 1 and the second value may be 0. For another example, the first value may be 0 and the second value may be 1.

In other words, the position of the start time domain symbol of the PSFCH in the slot is indicated by the value of the bit in the fifth bit bitmap.

Optionally, the fifth indication information includes a sixth bit bitmap, for each bit in the sixth bit bitmap, if the value of the bit is a first value, the time domain symbol corresponding to the bit is indicated to be a time domain symbol occupied by the PSFCH in one time slot, and if the value of the bit is a second value, the time domain symbol corresponding to the bit is indicated to be not a time domain symbol occupied by the PSFCH in one time slot. For example, the first value may be 1 and the second value may be 0. For another example, the first value may be 0 and the second value may be 1.

In other words, the position of the time domain symbol occupied by the PSFCH in the slot is indicated by the value of the bit in the sixth bit bitmap.

Taking the fifth bit bitmap as an example, assume that the fifth bit bitmap is [0,0,0,0,1,0,0,0,0,0,0,1,0,0], where symbol #4 and symbol #11 are set to 1, which means that symbol #4 and symbol #11 are the positions of the starting time domain symbols of the PSFCH, respectively, that is, the slot includes two sets of PSFCH transmission resources, a first set of PSFCH transmission resources is located in symbol #4 and symbol #5, and a second set of PSFCH transmission resources is located in symbol #11 and symbol #12, as in case 2 above.

It should be noted that, in the above example, it is assumed that in the resource pool configuration of the minislot, the structure of the corresponding PSFCH is still in PSFCH format 0 in the NR SL system, that is, one PSFCH occupies 1 PRB in the frequency domain, 2 time domain symbols in the time domain, and the PSFCH and its associated PSSCH are multiplexed in a TDM manner, and side feedback information is carried by a sequence. However, in the structure of the minislots, if the PSSCH and the PSFCH are multiplexed in the TDM manner, the system resource utilization rate is low, so that the PSFCH and the PSSCH can be supported to use the FDM multiplexing manner, where the number of time domain symbols occupied by the PSFCH is the same as the number of time domain symbols occupied by the minislots transmitting the PSCCH/PSSCH associated with the PSFCH, that is, if the PSCCH/PSSCH uses the minislot transmission and occupies a time domain symbols, the PSFCH corresponding to the PSCCH/PSSCH also occupies a time domain symbols. For example, the minislots configured by the resource pool occupy 7 time domain symbols, then PSFCH transmission resources may also be configured in the resource pool simultaneously, and the PSFCH transmission resources also occupy 7 time domain symbols. For convenience of description, the above PSFCH format occupying 2 time domain symbols is hereinafter referred to as a first PSFCH format, and the above PSFCH format occupying the same number of time domain symbols as the side transmission of the minislot is referred to as a second PSFCH format.

In some embodiments, the resource pool configuration information further includes sixth indication information, where the sixth indication information is used to indicate that the PSFCH format is the first PSFCH format or the second PSFCH format; wherein the first PSFCH format refers to a PSFCH format in which the PSFCH occupies 2 time domain symbols, and the second PSFCH format refers to a PSFCH format in which the same number of time domain symbols as the minislot occupy.

In other words, the resource pool configuration information includes therein indication information for determining a PSFCH format supported by the resource pool.

In this embodiment, the PSFCH format supported by the resource pool may be obtained through information in the resource pool configuration information.

In one implementation, the sixth indication information is carried in an information field in the resource pool configuration information; if the value of the sixth indication information is a fourth value, indicating that the PSFCH format supported by the resource pool is the first PSFCH format; and if the value of the sixth indication information is a fifth value, indicating that the PSFCH format supported by the resource pool is the second PSFCH format. For example, the fourth value may be 1 and the fifth value may be 0. For another example, the fourth value may be 0 and the fifth value may be 1.

In other words, the resource pool configuration information includes an information field, where the length of the information field is 1 bit, and the PSFCH format supported by the resource pool can be explicitly determined through the 1 bit. Illustratively, a value of 0 for the 1 bit indicates that the first PSFCH format is supported, and a value of 1 indicates that the second PSFCH format is supported.

In one implementation, the sixth indication information is information of frequency domain resources used for configuring the PSFCH in the resource pool configuration information; if the information for configuring the frequency domain resource of the PSFCH is a bit bitmap, indicating that the PSFCH format supported by the resource pool is the first PSFCH format; and if the information for configuring the frequency domain resource of the PSFCH is the information for indicating the initial frequency domain position and the frequency domain resource length, indicating the PSFCH format supported by the resource pool as the second PSFCH format.

Illustratively, if the information for configuring the frequency domain resources of the PSFCH is a side row PSFCH resource block Set (sl-PSFCH-RB-Set) in the resource pool configuration information indicated by a bit bitmap form, indicating that the PSFCH format supported by the resource pool is the first PSFCH format; and if the information for configuring the frequency domain resource of the PSFCH is the information for indicating the initial frequency domain position and the frequency domain resource length, indicating the PSFCH format supported by the resource pool as the second PSFCH format.

In one implementation, if the information for configuring the frequency domain resource of the PSFCH is a bit bitmap, indicating that the PSFCH format supported by the resource pool is the first PSFCH format; otherwise, indicating the PSFCH format supported by the resource pool as the second PSFCH format.

Illustratively, if the information for configuring the frequency domain resources of the PSFCH is a side row PSFCH resource block Set (sl-PSFCH-RB-Set) in the resource pool configuration information indicated by a bit bitmap form, indicating that the PSFCH format supported by the resource pool is the first PSFCH format; otherwise, indicating the PSFCH format supported by the resource pool as the second PSFCH format.

In one implementation, the method 100 may further include:

if the resource pool configuration information includes information for indicating the number of physical resource blocks PRB occupied by one PSFCH, determining that the PSFCH format supported by the resource pool is the second PSFCH format; otherwise, determining the PSFCH format supported by the resource pool as the first PSFCH format.

Illustratively, in the configuration information of the first PSFCH format, the following parameters for configuring the PSFCH are included:

in other words, when the resource pool configuration information includes other parameters for configuring the PSFCH transmission resources than the above parameters, it indicates that the resource pool supports the second PSFCH format, and otherwise, it indicates that the resource pool supports the first PSFCH format.

Specific embodiments of the present application will be described below with reference to the accompanying drawings.

Example 1:

in this embodiment, the resource pool configuration information includes first indication information, where the first indication information is used to indicate a position of a starting time domain symbol occupied by each of the at least one minislot in one slot and is used to indicate a number of time domain symbols occupied by each of the at least one minislot in one slot. For example, for each of the at least one minislot, the first indication information includes a first parameter and a second parameter; wherein the first parameter is used for indicating the position of a starting time domain symbol occupied by the micro time slot in one time slot, and the second parameter is used for indicating the number of time domain symbols occupied by the micro time slot in one time slot.

As shown in fig. 16, two minislots are configured in one slot, wherein the initial time domain symbol of the minislot 1 is a symbol #0, and the length is 7 time domain symbols; the starting time domain symbol of minislot 2 is symbol #7, which is 4 time domain symbols in length. Based on this, the resource pool configuration information includes first indication information for indicating the position of the starting time domain symbol occupied by the minislot 1 and the minislot 2 in one slot respectively and for indicating the number of time domain symbols occupied by each minislot in one slot. I.e. the first indication information comprises a first parameter and a second parameter; the first parameter is used for indicating the position of a starting time domain symbol occupied by the micro time slot 1 and the micro time slot 2 in one time slot respectively, and the second parameter is used for indicating the number of time domain symbols occupied by the micro time slot 1 and the micro time slot 2 in one time slot respectively. Specifically, the first parameter is {0,7}, and the second parameter is {7,4}.

The number of elements in the first parameter or the number of elements in the second parameter is used to indicate the number of micro time slots included in one time slot. I.e. the number of elements in the first parameter or the number of elements in the second parameter 2, it is indicated that the number of micro slots included in one slot is also 2.

In this embodiment, the resource pool configuration information may further include third indication information, where the third indication information is used to indicate an available time slot of the resource pool. For example, the third indication information is a third bit map, and for each bit in the third bit map, if the value of the bit is a first value, the time slot corresponding to the bit is indicated to be an available time slot of the resource pool, and if the value of the bit is a second value, the time slot corresponding to the bit is indicated to be not an available time slot of the resource pool. In other words, the resource pool configuration information further includes indication information for indicating the available time slots of the resource pool, and the indication information for indicating the available time slots of the resource pool may be implemented in the form of a bit map.

Combining the third indication information for indicating the available time slots of the resource pool and the first indication information in this embodiment, the time domain resources of the micro time slots in the resource pool can be determined.

As shown in fig. 17, the available time slots in the resource pool are indicated by a bit map 1 (i.e., [1,1,1,0,0,0,0,0,0,0 ]) of 10 bits in length, and the available time slots in the resource pool can be determined based on the bit map 1 being periodically repeated in the time domain. In addition, the resource pool configuration information further includes information for configuring time domain resources of the micro time slot 1 and the micro time slot 2 in the time slot, that is, the first indication information, based on the first indication information, it can be known that a starting symbol of the micro time slot 1 is a symbol #0, and occupies 7 time domain symbols; the starting symbol of minislot 2 is symbol #7, occupying 4 time domain symbols.

Example 2:

in this embodiment, the resource pool configuration information includes a first bit map and second indication information, where the first bit map is used to indicate a position of a start time domain symbol occupied by each of the at least one minislot in one slot; the second indication information is used for indicating the number of time domain symbols occupied by each micro slot in one slot. For example, the second indication information is the second parameter described above.

As shown in fig. 16, two minislots are configured in one slot, wherein the initial time domain symbol of the minislot 1 is a symbol #0, and the length is 7 time domain symbols; the starting time domain symbol of minislot 2 is symbol #7, which is 4 time domain symbols in length. Based on this, the resource pool configuration information includes a first bit map for indicating the positions of the start time domain symbols occupied by the minislot 1 and the minislot 2 in one slot, respectively, and second indication information; the second indication information is used for indicating the number of time domain symbols occupied by the micro time slot 1 and the micro time slot 2 in one time slot respectively. Specifically, the positions of the start time domain symbols occupied by the minislot 1 and the minislot 2 in one slot, respectively, are indicated by the following bit maps: [1,0,0,0,0,0,0,1,0,0,0,0,0,0], symbol #0 and symbol #7 represent the starting time domain symbols of said minislot 1 and said minislot 2, respectively. In addition, the number of time domain symbols occupied by the micro time slot 1 and the micro time slot 2 in one time slot is respectively indicated by a second parameter, wherein the number of time domain symbols of the micro time slot 1 is 7, and the number of time domain symbols of the micro time slot 2 is 4, namely the second parameter is {7,4}; and combining the first bit bitmap to indicate the positions of the initial time domain symbols occupied by the micro time slot 1 and the micro time slot 2 in one time slot respectively, and the number of the time domain symbols occupied by the micro time slot 1 and the micro time slot 2 in one time slot respectively indicated by the second indication information, so that the time domain resources occupied by the micro time slot 1 and the micro time slot 2 in one time slot respectively can be obtained.

The number of elements in the second parameter is used to indicate the number of micro time slots included in one time slot. I.e. the number of elements in the second parameter is 2, it is indicated that the number of minislots included in one slot is also 2. Or, the number of 1 values in the first bit map is used to indicate the number of micro time slots included in one time slot. That is, the number of 1 in the first bit map is 2, which indicates that the number of minislots included in one slot is also 2.

Combining the third indication information for indicating the available time slots of the resource pool with the first bit map and the second indication information in this embodiment, the time domain resources of the micro time slots in the resource pool can be determined.

As shown in fig. 18, the available time slots in the resource pool are indicated by a bit map 1 (i.e., [1,1,1,0,0,0,0,0,0,0 ]) of 10 bits in length, and the available time slots in the resource pool can be determined based on the bit map 1 being periodically repeated in the time domain. In addition, the resource pool configuration information further includes bit map 2 (i.e., [1,0,0,0,0,0,0,1,0,0,0,0,0,0 ]) for configuring the starting time domain position of the time domain of the micro-slot in the time slot, and further, the time domain resource of the micro-slot included in the resource pool can be determined by combining the number of time domain symbols occupied by the micro-slot, i.e., the information indicated by the second indication information. One time slot in the resource pool comprises two micro time slots, wherein the initial symbol of the micro time slot 1 is symbol #0 and occupies 7 time domain symbols; the starting symbol of minislot 2 is symbol #7, occupying 4 time domain symbols.

Example 3:

in this embodiment, the at least one micro slot includes only one micro slot, and the resource pool configuration information includes a second bit map, where the second bit map is used to indicate a time domain symbol occupied by the one micro slot in one slot.

If only one minislot is included in one slot in the resource pool, the time domain information of the minislot may be indicated by a bit map, for example, for fig. 19, the second bit map thereof may be represented as [1,1,1,1,1,1,1,0,0,0,0,0,0,0]; for example, for fig. 20, its second bit map may be denoted as [0,0,0,0,0,0,0,1,1,1,1,0,0,0]. That is, the value of the bit in the second bit bitmap being 1 indicates that the time domain symbol corresponding to the bit is the time domain symbol in the one micro slot.

Combining the third indication information for indicating the available time slots of the resource pool and the second bit map in this embodiment, the time domain resources of the micro time slots in the resource pool can be determined.

As shown in fig. 21, the available time slots in the resource pool are indicated by a bit map 1 (i.e., [1,1,1,0,0,0,0,0,0,0 ]) of 10 bits in length, and the available time slots in the resource pool can be determined based on the bit map 1 being periodically repeated in the time domain. In addition, the resource pool configuration information may further include bit bitmap 3 (i.e., [1,1,1,1,1,1,1,0,0,0,0,0,0,0 ]) for configuring the position of the start time domain symbol of the micro slot in the slot and the number of occupied time domain symbols, so that the time domain resource of the micro slot included in the resource pool can be determined. One slot in the resource pool includes one micro slot, the initial symbol of which is symbol #0, and occupies 7 time domain symbols.

Example 4:

in this embodiment, for each of the at least one minislot, the number of time domain symbols occupied by the minislot in one slot includes: the PSSCH-occupied time domain symbol, the PSFCH-occupied time domain symbol, and the GP symbol.

Fig. 22 is another schematic diagram of a time domain resource of a minislot within a slot in a resource pool according to an embodiment of the present application.

As shown in fig. 22, it is assumed that one slot in the resource pool includes one minislot, whose initial symbol is symbol #0, and occupies 7 time domain symbols. The 7 time domain symbols occupied by the one micro slot include a time domain symbol for PSFCH transmission, and a corresponding GP symbol, wherein the first 7 time domain symbols in the slot are the time domain symbols occupied by the one micro slot, and additionally, the time domain symbols for PSFCH transmission are configured, where the time domain symbols occupied by the PSSCH are symbols #0, #1, #2, and the time domain symbols occupied by the PSFCH are symbols #4, #5, and the time domain symbols #3 and #6 are GP symbols.

Optionally, the number of time domain symbols occupied by the minislot in one slot may further include: the symbols occupied by the PSCCH.

It should be noted that, for each micro slot of the at least one micro slot, if the number of time domain symbols occupied by the micro slot in one slot is less than or equal to the third value, the number of time domain symbols occupied by the micro slot in one slot only includes the time domain symbols occupied by the PSSCH and the GP symbols. In other words, for each of the at least one minislot, if the number of time domain symbols occupied by the minislot in one slot is less than or equal to a third value, PSFCH transmission resources are not configured in the resource pool. It should be noted that, the third value may be preconfigured or configured by a network device, which is not limited in particular in the embodiment of the present application. In some implementations, the "pre-configuration" may be implemented by pre-storing corresponding codes, tables, or other manners in which related information may be indicated in devices (including, for example, terminal devices and network devices), and the present application is not limited to a specific implementation thereof. Such as pre-configured, may refer to what is defined in the protocol. Alternatively, the "protocol" may refer to a standard protocol in the communication field, and may include, for example, an LTE protocol, an NR protocol, and related protocols applied to a future communication system, which is not particularly limited by the present application.

Example 5:

in this embodiment, the resource pool configuration information further includes fifth indication information, where the fifth indication information is used to indicate time domain resources of the physical sidelink feedback channel PSFCH. The fifth indication information includes a third parameter for indicating a period of time domain resources of the PSFCH and a fourth parameter for indicating a minimum time interval between physical sidelink shared channels PSSCHs associated with the PSFCH. Optionally, the third parameter is expressed as the number of micro time slots, and the fourth parameter is expressed as the number of micro time slots.

As shown in fig. 23, one slot includes 2 minislots, and the period of the PSFCH is 2 minislots, i.e., one minislot for transmitting the PSFCH is included every 2 minislots. It is assumed that when the third parameter is expressed by the number of minislots, if the third parameter takes a value of 2, that is, when the terminal receives the PSCCH/PSSCH at time n (or logical slot n), the terminal transmits feedback on the side of the first available PSFCH transmission resource in the resource pool after time n+2 (or logical slot n+2). As shown in fig. 23, when the terminal receives PSCCH/PSSCH in minislot 4, the first PSFCH transmission resource after minislot 6, i.e., the PSFCH transmission resource in minislot 7, sends side row feedback; when the terminal receives the PSCCH/PSSCH in minislot 5, the first PSFCH transmission resource after minislot 7, i.e., the PSFCH transmission resource in minislot 7, sends side row feedback.
