For example, the length L1 of the resource bitmap 1 is an integer multiple of the number of slots or an integer multiple of the number of milliseconds corresponding to the resource pattern 1. For another example, the length L2 of the resource bitmap 2 is an integer multiple of the number of slots or an integer multiple of the number of milliseconds corresponding to the resource pattern 2.

As a further alternative embodiment, in a case that the resource configuration information includes N4 resource periods, the resource indication information includes N4 resource bitmaps corresponding to the N4 resource periods, respectively; n4 is an integer greater than or equal to 2.

Preferably, u=1, or U is an integer multiple of the accuracy indicated by the resource configuration information (e.g. the resource configuration information accuracy is 2, then u=2).

For example, if the frequency at which the side link communication or transmission is performed is located at FR1, u=2; if the frequency at which the side link communication or transmission is performed is located at FR2, u=4.

In the above embodiment of the present invention, the first resource may include an available resource and/or an unavailable resource, where the available resource included in the first resource corresponds to at least a portion of bits in the resource bitmap.

Wherein the available resources are resources meeting preset requirements or uplink resources. Specifically, for example, an uplink slot, or a slot containing an uplink symbol satisfying a preset requirement. The available resources may be understood as resources that may be used for SL transmissions.

Alternatively, the sidelink synchronization resource may be understood as a resource for transmitting a sidelink synchronization signal. Specifically, the resources used for transmitting the SLSS (side link synchronization signal ) are, for example, subframes or slots in which the SLSS or S-SSB (side link-synchronization signal block) is located. Specifically, it may be a resource corresponding to at least one of a parameter SL-SSB-time allocation (sidelink synchronization signal block time allocation) and a parameter syncoffsetidentifier (synchronization offset indication).

Unavailable resources are resources which do not contain uplink symbols meeting preset requirements, such as downlink resources and flexible resources; for another example, symbols X to (X+Y-1) are not at least one of uplink resources; unavailable resources may be understood as resources that may not be used for SL transmissions.

Optionally, the preset requirement is that the symbols X to (x+y-1) are uplink symbols, or that the symbols X to (x+y-1) are used for SL.

The number of available resources may be the number of available resources over a period of time, e.g., the number of available resources over a period or pattern, and the number of available resources over different periods or different patterns may be the same or different, without limitation.

The number of unavailable resources may be the number of unavailable resources for a certain period of time, for example, the number of unavailable resources for a certain period or pattern, and the number of unavailable resources for different periods or different patterns may be the same or different, without limitation.

Optionally, the available resources included in the first resource correspond to at least part of bits in the resource bitmap, including:

a) If there is a resource bitmap, the lower B bits or the upper B bits of the resource bitmap correspond to the available resources, and B is the number of the available resources.

b) If two resource bitmaps exist, the lower A1 bit or the upper A1 bit of the resource bitmap 1 corresponds to the available resources; and/or the low A2 bits or the high A2 bits of the resource bitmap 2 correspond to the available resources; a1 and A2 are the number of available resources corresponding to the two resource bitmaps respectively.

c) If the resource period P1 and the resource period P2 correspond to one resource bitmap, bits from b1+ (p1+p2) n+1 to b1+ (p1+p2) n+a1 of the resource bitmap, bits from b2+p1+ (p1+p2) n+1 to b2+p1+ (p1+p2) n+a2 of the resource bitmap correspond to available resources; n=0 … period/(p1+p2) -1, where A1, A2 are P1, the number of available resources in P2, B1, B2 are P1, the number of unavailable resources in P2, and period is the resource bitmap period or length.

d) If the resource periods P1 and P2 correspond to the resource bit map 1 and the resource bit map 2, bits from b1+ (p1+p2) n+1 to b1+ (p1+p2) n+a1 of the resource bit map 1 correspond to the available resources, and/or bits from b2+p1+ (p1+p2) n+1 to b2+p1+ (p1+p2) n+a2 of the bit map 2 correspond to the available resources; n=0 … period/(p1+p2) -1, where A1, A2 are the number of available resources within P1, P2; b1 B2 is the number of unavailable resources in P1, P2, and period is the period or length of resource bitmap 1 or 2.

e) If the resource period P1 corresponds to a resource bitmap, bits from the b1+p1×n+1 to the b1+p1×n+a1 of the resource bitmap correspond to available resources; n=0 … (period/P1-1), where A1 is the number of available resources in P1, B1 is the number of unavailable resources in P1, and period is the resource bitmap period or length.

For example, when two resource patterns are included, the number of available resources in each resource pattern is A1 and A2:

the rear A1 resources in the resource pattern 1 correspond to the low A1 bits of the resource bitmap 1, and the rear A2 resources in the pattern 2 correspond to the low A2 bits of the resource bitmap 2;

or, the later A1 resources in pattern 1 correspond to the higher A1 bits of the resource bitmap 1, and the later A2 resources in pattern 2 correspond to the higher A2 bits of the resource bitmap 2.

For example, when two resource periods P1 and P2 are included, the number of available resources in each resource period is A1 'and A2':

the latter A1 'resources in the resource period P1 correspond to the low A1' bits of the resource bitmap 1, and the latter A2 'resources in the resource period P2 correspond to the low A2' bits of the resource bitmap 2;

or, the later A1 'resources in the resource period P1 correspond to the high A1' bits of the resource bitmap 1, and the later A2 'resources in the resource period P2 correspond to the high A2' bits of the resource bitmap 2.

For example, when 1 resource pattern is included, the number of available resources in the resource pattern is a1″:

the rear A1 'resources in the pattern correspond to the low A1' bits of the resource bitmap;

or, the latter A1 "resources in the pattern correspond to the high A1" bits of the resource bitmap.

For example, when 1 resource period P1 is included, the number of available resources in the resource period is A1' ":

a1 '"resources after the resource period correspond to low A1'" bits of the resource bitmap;

or, A1 '"number of resources after the resource period corresponds to a high A1'" number of bits of the resource bitmap.

As an alternative embodiment, step 102 includes:

and if the bit value of the resource bitmap corresponding to the available resource is a first value and the available resource does not belong to the target side link synchronous resource, determining the available resource as the resource for side link transmission.

For example, if the first value is 1, the bit=1 and the resource does not belong to the target sidelink synchronization resource, then the available resource corresponding to the bit is used for the resource of the sidelink transmission (i.e., the available resource belongs to the sidelink resource pool); or conversely, when the first value is 0, the bit=0 and the resource does not belong to the target sidelink synchronization resource, the available resource corresponding to the bit is used for the resource of the sidelink transmission (i.e., the available resource belongs to the sidelink resource pool).

As an alternative embodiment, the method further comprises:

when determining the resource used for the side link transmission in the first resource, ignoring bits corresponding to unavailable resources in the first resource and/or bits corresponding to target side link synchronous resources;

And/or the number of the groups of groups,

when the resources for side link transmission in the first resources are determined, the value of the bit corresponding to the unavailable resources in the first resources and/or the bit corresponding to the target side link synchronous resources is a second value; the second value indicates that the resource is not a resource of a resource pool for sidelink transmission, i.e. the resource does not necessarily belong to a sidelink resource pool; for example, assuming that the second value is 0, the user does not desire the value of the bit corresponding to the unavailable resource and/or the target sidelink synchronization resource to be the first value; or the user expects or presumes that the value of the bit corresponding to the unavailable resource and/or the target side link synchronization resource is a second value.

And/or the number of the groups of groups,

upon determining resources of the first resources for sidelink transmission, determining that unavailable resources and/or target sidelink synchronization resources of the first resources are not used for sidelink transmission.

Optionally, determining that the unavailable resource and/or the target sidelink synchronization resource in the first resource cannot be used for sidelink transmission refers to determining that the unavailable resource and/or the target sidelink synchronization resource in the first resource does not belong to the sidelink resource pool.

Preferably, the target sidelink synchronization resource comprises at least one of:

The determined resources for the sidelink transmission belong to sidelink synchronization resources of the bandwidth part BWP; for example, in determining resources belonging to the side link resource pool of BWP j, the target side link synchronization resource is a side link synchronization resource of BWP j;

the determined resources for the sidelink transmission belong to the sidelink synchronization resources of all activated BWPs in the carrier; for example, in determining resources belonging to the sidelink resource pool of BWP j within carrier k, the target sidelink synchronization resource is the sidelink synchronization resource of all active BWP within carrier k;

the determined resources for the sidelink transmission belong to the sidelink synchronization resources of all BWPs in the carrier; for example, in determining resources belonging to the sidelink resource pool of BWP j in carrier k, the target sidelink synchronization resource is a sidelink synchronization resource of all BWP in carrier k;

the determined resources for the sidelink transmission belong to sidelink synchronization resources in the carrier wave; for example, in determining resources of the sidelink resource pool within carrier k, the target sidelink synchronization resource is a sidelink synchronization resource within carrier k;

For example, the control node provides information of target sidelink synchronization resources of LTE (e.g., the number of sidelink synchronization resources used for LTE SLSS transmission and/or the time domain location of sidelink synchronization resources used for LTE SLSS transmission), then the target sidelink synchronization resources at least include the target sidelink synchronization resources of LTE.

For another example, the control node provides information of target sidelink synchronization resources of the NR (e.g., the number of sidelink synchronization resources used for NR SLSS transmission and/or the number of resources used for transmission of NR SLSS within the sidelink synchronization resources) and information of target sidelink synchronization resources of the LTE (e.g., the number of sidelink synchronization resources used for LTE SLSS transmission and/or the time domain location of sidelink synchronization resources used for LTE SLSS transmission), then the target sidelink synchronization resources include the target sidelink synchronization resources of the NR and the target sidelink synchronization resources of the LTE.

for example, in connection with a TDD pattern period, specifically, M1 and/or M2 is 0.5;0.625;1, a step of; 1.25;2;2.5;3, a step of; 4, a step of; 5, a step of; 10;20, at least one value of 20;

in relation to the delay requirement (latency requirement), in particular, M1 and/or M2 is at least one value of 3, 10, 20, 25, 50, 100, 500;

in connection with a reservation period (reservation period), in particular, M1 and/or M2 is at least one value of 1 to 99, 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000;

in relation to a monitoring window (sensing window) parameter, for example, in relation to a monitoring window start parameter T0 or sl-sensing window, specifically, M1 and/or M2 is 100 and/or 1100;

in relation to a selection window parameter, for example in relation to a selection window end parameter T2 or sl-selection window, in particular M1 and/or M2 is at least one value of 1,5, 10, 20;

In relation to the maximum time range W in which SCI indicates resources, in particular M1 and/or M2 is 32;

in relation to the synchronization signal period, in particular, M1 and/or M2 is 160;

in relation to the maximum interval between synchronization signals, M1 and/or M2 is in particular 80. As an alternative embodiment, the resource configuration information includes at least one of:

uplink and downlink resource configuration information; for example, TDD-UL-DL-configCommon (time division duplex uplink and downlink common configuration), and/or TDD-UL-DL-configDedicated (time division duplex uplink and downlink dedicated configuration);

side link resource configuration information; for example, SL-TDD-config (side link time division duplex configuration);

synchronizing resource configuration information; such as SL-SyncConfig (sidelink synchronization resource configuration).

Preferably, the terminal determines the resources for the sidelink transmission in the first resources based on the bit correspondence of the resource bitmap and the first resources indicated by the sidelink resource configuration information. For example, the resources for the sidelink transmission in the first resource are determined according to bit correspondence of the SL-TDD-config indication first resource and the resource bitmap. Specifically, assuming that the SL-TDD-config indicates that the resource period is 10ms, and there are 10 available resources (slots) and 10 unavailable resources (slots) within 10ms, the 20 slots correspond to at least part of bits in the bitmap, and the resource for sidelink transmission in the first resource is determined according to the indication of the resource bitmap.

For example, if the synchronization source of the terminal is other terminals outside the coverage, the terminal may acquire the first resource according to TDD-UL-DL-configcommon or SL-TDD-Config in the pre-configuration;

for example, if the synchronization source of the terminal is other terminals within the coverage but the terminal itself is out of the coverage, the first resource may be acquired based on the acquired SL-TDD-Config;

for example, the first resource may be acquired based on TDD-UL-DL-configcommon of the SIB, as if the terminal is within the coverage, or other terminal or base station where the terminal is within the coverage and the synchronization source of the terminal is within the coverage.

For example, the first resource may be acquired based on the TDD-UL-DL-configcommon of the system information block SIB, if the terminal is in a connected state and/or the synchronization source of the terminal is a connected state terminal within the coverage. Optionally, in the foregoing embodiment of the present invention, the acquiring resource configuration information includes any one of the following:

the terminal determines own resource configuration information;

receiving a broadcast message, wherein the broadcast message carries the resource configuration information; for example, a sidelink broadcast channel PSBCH, or a master information block MIB carried by the PSBCH;

receiving a side link system information block SIB, wherein the side link system information block carries the resource configuration information; i.e., SIBs carrying sidelink related configuration information, e.g., SIB X;

Receiving a side link Radio Resource Control (RRC) signaling, wherein the RRC signaling carries the resource configuration information; namely RRC signaling carrying sidelink related configuration information, such as NR sidelink dedicated configuration signaling (SL-configdedicatenr), and/or RRC signaling of PC5, such as RRC sidelink reconfiguration signaling (rrcrecon configuration sidelink) or RRC sidelink reconfiguration complete signaling (rrcrecon configuration sidelink);

acquiring preconfigured resource configuration information;

predefined (e.g., protocol defined) resource configuration information is obtained.

In summary, in the embodiment of the present invention, the first resource is indicated by the resource configuration information, and at least one resource bitmap is carried by the resource indication information, where a bit of the resource bitmap corresponds to a resource included in the first resource, and the terminal can determine, according to the indication of the resource bitmap, a resource used for sidelink transmission in the first resource, so as to implement sidelink transmission.

In order to more clearly describe the resource determining method provided by the embodiment of the present invention, the resource determining method is described below in connection with several examples.

Example one, resource period, resource pattern, resource bitmap

If the resource allocation information includes one resource period, the resource period=the time domain size of the resource pattern Z1, or the period of the resource pattern Z1.

For example, the resource pattern is a TDD pattern, and only one TDD pattern has a period of 10ms, and the resource period is 10ms×z1. For another example, the resource pattern is a TDD pattern, and there is only one TDD pattern, where the time domain size is 80 slots, and the resource period is 80×z1 slots. Preferably, z1=1.

If the resource allocation information includes a plurality of resource periods, each resource period is an integer multiple of the number of time domain units corresponding to the resource pattern, or the resource allocation information includes 1 resource period, and the resource period is an integer multiple of the sum of the plurality of resource periods.

For example, the resource pattern is a TDD pattern, and there are 2 TDD patterns, and the periods thereof are 3ms and 2ms, respectively, and then the resource periods P1 and P2 are divided into 3ms×z2 and 2ms×z2; or the resource period is 5ms x z2.

For another example, the resource pattern is a TDD pattern, and there are 2 TDD patterns, and the periods thereof are 6 slots and 4 slots, respectively, so that the resource periods P1 and P2 are divided into 6×z2 slots and 4×z2 slots; further, or the resource period is 10×z2 slots. Preferably, z2=1.

c) Optionally, the resource period is a SLSS (SideLink Synchronization Signal ) period Z3 or an S-SSB (SideLink-Synchronization Signal Block, sideLink-synchronization signal block) period Z3, and the unit of the period may be milliseconds (ms) or slots (slots). For example, the SLSS period is 160ms, then the resource period is 160ms×z3; for another example, when subcarrier scs=30 kHz, the S-SSB period is 320 slots, so that the resource period can be expressed as 320×z3 slots. Preferably, z3=1.

Wherein Z1, Z2 and Z3 are positive integers.

If the resource allocation information comprises two resource patterns, the resource indication information comprises 1 or two resource bitmaps; if 2 resource bitmaps are included, optionally, the length L1 of the resource bitmap 1 is an integer multiple of the ms number or an integer multiple of the time slot number corresponding to the resource pattern 1; optionally, the length L2 of the resource bitmap 2 is an integer multiple of the ms number or an integer multiple of the slot number corresponding to the resource pattern 2.

If the resource allocation information includes a resource pattern, the resource indication information includes a resource bitmap: optionally, the length L1 of the resource bitmap is an integer multiple of the ms number or an integer multiple of the slot number corresponding to the resource pattern.

If the resource allocation information comprises two resource periods, P1 and P2, the resource indication information comprises 1 or two resource bitmaps; if 2 resource bitmaps are included, optionally, the length L1 of the resource bitmap 1 is an integer multiple of the ms number corresponding to P1 or an integer multiple of the slot number (or understood to be an integer multiple of P1); optionally, the length L2 of the resource bitmap 2 is an integer multiple of the ms number corresponding to P2 or an integer multiple of the slot number (or understood to be an integer multiple of P2).

If the resource allocation information comprises a resource period P1, the resource indication information comprises a resource bitmap; optionally, the length L1 of the resource bitmap is an integer multiple of the ms number corresponding to P1 or an integer multiple of the slot number (or understood to be an integer multiple of P1).

Example two, the corresponding relation calculation mode of the bits of the available resource and the resource bitmap

The available resources in the first resources indicated by the resource configuration information correspond to at least part of bits in the resource bitmap, and the corresponding mode comprises:

a) The low A bits or the high A bits of the resource bitmap correspond to available resources, and A is the number of the available resources;

for example, the bitmap is 80 bits, a=20, and then the lower 20 bits of the 80 bits correspond to the available resources, or the higher 20 bits of the 80 bits correspond to the available resources.

b) If there are two resource bitmaps, the low A1 bit or the high A1 bit of the bitmap 1 and/or the low A2 bit or the high A2 bit of the bitmap 2 correspond to the available resources respectively, and A1/A2 is the number of the available resources.

For example, bitmap 1 is 80bit, a 1=20, bitmap 2 is 80bit, a2=40, then:

the low 20 bits in bitmap 1, or the high 20 bits in bitmap 1, correspond to the available resources;

and/or the lower 40 bits in bitmap 2, or the upper 40 bits in bitmap 2, correspond to the available resources.

Example three, the correspondence between available resources and bits of the resource bitmap is calculated

a) B1+ (p1+p2) n+1 to b1+ (p1+p2) n+a1 bits, b2+p1+ (p1+p2) n+1 to b2+p1+ (p1+p2) n+a2 bits, and available resources; n=0 … period/(p1+p2) -1, where the resource period includes two resource periods P1 and P2, A1, A2 is P1, the number of available resources in P2, B1, B2 is P1, the number of unavailable resources in P2, and period is the resource bitmap period or length.

For example, period=160 ms; p1=p2=10ms; b1 =5; a1 =5; b2 =2; a2 =8, the resource bitmap length is 160, and the bits of the resource bitmaps 6-10, 12-20, 26-30, 32-40, 46-50, 52-60, 66-70, 72-80, 86-90, 92-100, 106-110, 112-120, 126-130, 132-140, 146-150, 152-160 correspond to the available resources.

b) The resource indication information comprises two resource bitmaps, wherein the B1+ (P1+P2) n+1 to B1+ (P1+P2) n+A1 bits of the resource bitmap 1 and/or the B2+P1+ (P1+P2) n+1 to B2+P1+ (P1+P2) n+A2 bits of the resource bitmap 2 correspond to available resources; n=0 … period/(p1+p2) -1, where the resource period includes two resource periods P1 and P2, A1, A2 is the number of available resources in P1, P2, B1, B2 is the number of unavailable resources in P1P 2, and period is the resource bitmap period or length.

For example, period=160 ms; p1=p2=10ms; b1 =5; a1 =5; b2 =; a2 When the length of the resource bitmap 1 is 160 and the length of the resource bitmap 2 is 160, bits of bits 6 to 10, 26 to 30, 46 to 50, 66 to 70, 86 to 90, 106 to 110, 126 to 130, 146 to 150 of the bitmap 1, bits of bits 12 to 20, 32 to 40, 52 to 60, 72 to 80, 92 to 100, 112 to 120, 132 to 140, 152 to 160 of the bitmap 2 correspond to available resources.

c) Bits of the b1+p1×n+1 to b1+p1×n+a1 of the resource bitmap correspond to available resources; n=0 … (period/P1-1), where the resource period comprises 1 period P1, A1 is the number of available resources within P1, B1 is the number of unavailable resources within P1, and period is the resource bitmap period or length.

For example, period=160 ms; p1=20 ms; b1 =15; a1 =5, the resource bitmap length is 160, and the bits of the resource bitmaps 16-20, 36-40, 56-60, 76-80, 96-100, 116-120, 136-140, 156-160 correspond to the available resources.

Example four: the first resource contains resource and bit corresponding of the resource bitmap

The resource indicated by the resource configuration information may correspond to bits in the resource bitmap: each U time slot indicated by the configuration information corresponds to a bit in the resource bitmap;

Preferably, u=1.

Alternatively, if the frequency at which SL communication or transmission is performed is located at FR1, u=2.

Alternatively, if the frequency at which SL communication or transmission is performed is located at FR2, u=4.

Optionally, U is an integer multiple of the accuracy of the resource configuration information configuration; for example, the resource configuration information indicates that the accuracy of the resource is 8 slots, then u=8; for example, the resource configuration information indicates that the accuracy of the resource is 4 slots, then u=4; for example, the resource configuration information indicates that the accuracy of the resource is 2 slots, then u=2; for example, the resource configuration information indicates that the accuracy of the resource is 1 slot, then u=1. Specifically, for example, the resource configuration information is SL-TDD-Config, and the accuracy is 2 slots when the SL-TDD-Config indicates resources, or the number of resources indicated by the SL-TDD-Config is a multiple of 2 slots, or u=2 when the minimum difference between the number of resources that can be indicated by the SL-TDD-Config is 2 slots.

The accuracy of the configuration of the resource configuration information in the above description is G, and may be interpreted as that the number of resources indicated by the resource configuration information is a multiple of G, or may be interpreted as that the minimum difference between the numbers of resources that the resource configuration information may indicate is G. The accuracy of G may be G slots or G milliseconds.

Alternatively, u=2 ^μ ；μ＝log ₂ (SCS/a), SCS is the subcarrier spacing of the side link, a is the reference subcarrier spacing, e.g. a=15 kHz or 30kHz or 60kHz. If a=15 kHz, that is, each ms indicated by the resource allocation information corresponds to a bit in the resource indication information. For example, SL scs=30 kHz, then u=2 ^μ ＝2 ¹ =2, where every 2 slots corresponds to one bit in the resource bitmap, respectively.

Example five

1. The terminal acquires resource configuration information and resource indication information, and applies the resource indication information to a first resource { S } indicated by the resource configuration information;

2. the resource in the first resource indicated by the resource configuration information (denoted as set { S }) has a correspondence with the bit of the resource bitmap.

3. The terminal determines the resources of the resource pool for the side link transmission according to the resource indication information, and specifically comprises at least one of the following:

a) If a bit or bits corresponds or corresponds to an available resource, e.g., the bit=a first value and the resource does not belong to a sidelink synchronization resource, the corresponding available resource is a resource of a resource pool for sidelink transmission;

b) If some or some bits correspond to downlink resources, flexible resources, resources containing uplink symbols but not meeting preset requirements, and belong to at least one of the side link synchronization resources (i.e. resources for SLSS transmission), the user ignores the bits.

Specifically, a sidelink transmission occupies symbols 0-12 in a time slot, the resource indication information includes a bitmap with a length of 80, wherein the first 59 bits correspond to a downlink time slot, the first 10 symbols of the time slot corresponding to the 60 th bit are flexible symbols, the last 4 symbols are uplink symbols, and the last 20 bits correspond to 20 uplink time slots. Let us assume that the last 20 slots of the 80 slots corresponding to the resource indication information are available slots.

When the terminal determines the resource of the resource pool for the side link transmission, the first 60 bits in the bitmap are ignored, and for the last 20 bits, if the time slot corresponding to one or some bits is used for the SLSS transmission, the user also ignores the bits. For the remaining available time slots, if its corresponding bit=1, the resources of the time slot are considered to belong to the resources of the resource pool for the sidelink transmission (which may be referred to as sidelink resource pool).

For example, assuming that the bit corresponding to the last 20 slots has a value of 1111 0000 0000 1111 and the last slot is used for SLSS, the 1 st to 4 th slots and the 13 th to 15 th slots of the last 20 slots belong to the sidelink resource pool.

Example six

Assume that a sidelink resource pool is associated with a set of resources. Wherein P is _SL For the period of the resource pool, assume units of milliseconds (ms). The ith period of the resource pool starts at the slot

Ending in time slot

Wherein->

Is the number of slots within one subframe; i is more than or equal to 0 and less than 10240/P _SL 。

Alternatively, assume that a sidelink resource pool is associated with a set of resources. Wherein P is _SL For the period of the resource pool, assume a unit of time slot. The ith period of the resource pool starts at the slot

Ending in time slot->

Wherein the method comprises the steps of

Wherein->

Is the number of slots within a subframe.

Assume that the corresponding length of the resource pool is L _bitmap Bitmap of (2)

In a resource pool period, a user determines the resources of the resource pool according to the following steps:

the time slots in the period are arranged according to the ascending sequence of the time slot index, which is expressed as

If a time slot l _j Is an available time slot (for example, an uplink time slot), or a time slot meeting a preset requirement, and the corresponding bit b _j The time slot belongs to the resource of the resource pool for the sidelink transmission, =1;

if a time slot l _j Is a downlink slot, or a flexible slot, or a resource for SLSS, or does not meet a preset requirement, the slot does not belong to the resource of the resource pool for sidelink transmission.

For example, the control node provides information about the target sidelink synchronization resource of LTE, such as the number of sidelink synchronization resources used for LTE SLSS transmission, where the resources used for SLSS in the above steps at least include the target sidelink synchronization resource of LTE. I.e. the target sidelink synchronization resource of LTE does not belong to the resource pool. In particular, for example, by The number of the side link synchronization resources for the LTE SLSS transmission is Q, and the resources for the SLSS in the above embodiment are Q subframes, or q×2 ^μ The number of time slots, mu is log ₂ (SCS/15 kHz), the SCS is the SCS of SL. Further, the NR control node, e.g. the gNB, provides information of target sidelink synchronization resources of LTE, and the terminal determines that the target sidelink synchronization resources comprise the target sidelink synchronization resources of LTE when determining the resources of the NR sidelink resource pool. Optionally, the terminal determines: the target sidelink synchronization resource of LTE does not belong to the NR sidelink resource pool, and/or a bit in the resource bitmap corresponding to the target sidelink synchronization resource of LTE is a second value, and/or the terminal ignores a bit in the resource bitmap corresponding to the target sidelink synchronization resource of LTE.

For example, the control node provides information on the target sidelink synchronization resources of the NR (e.g., the number of sidelink synchronization resources used for NR SLSS transmission and/or the number of resources used for transmission of the NR SLSS within the sidelink synchronization resources), where the resources used for the SLSS in the above steps comprise the target sidelink synchronization resources of the NR. I.e. the target sidelink synchronization resource of said NR does not belong to the resource pool. Specifically, for example, the number of sidelink synchronization resources for NR SLSS transmission is Q, and the number of resources for NR SLSS transmission within each sidelink synchronization resource is L _SLSS The resource for SLSS in the above embodiment is q×l corresponding to the target sidelink synchronization resource with NR _SLSS And each time slot.

Further, the NR control node, e.g., gNB, provides the NR's target-side-link synchronization resource, and the terminal determines that the target-side-link synchronization resource comprises the NR's target-side-link synchronization resource when determining the resources of the NR-side-link resource pool. Optionally, the terminal determines: the target sidelink synchronization resource of the NR does not belong to the NR sidelink resource pool, and/or a bit in a resource bitmap corresponding to the target sidelink synchronization resource of the NR is a second value, and/or the terminal ignores the bit in the resource bitmap corresponding to the target sidelink synchronization resource of the NR.

For example, the control node provides information of the target sidelink synchronization resource of the NR (e.g., the number of sidelink synchronization resources for NR SLSS transmissions, and/or the sidelinkThe number of resources used to transmit the NR SLSS within the link synchronization resources) and information of the target sidelink synchronization resources of LTE (e.g., the number of sidelink synchronization resources transmitted by the LTE SLSS), where the resources used for the SLSS in the above steps include the target sidelink synchronization resources of NR and the target sidelink synchronization resources of LTE. I.e. the target-side-link synchronization resource of the NR and the target-side-link synchronization resource of LTE do not belong to a resource pool. Specifically, for example, the number of side link synchronization resources for LTE SLSS transmission is Q1, the number of side link synchronization resources for NR SLSS transmission is Q2, and the resources for NR SLSS transmission and the synchronization resources for LTE SLSS transmission do not overlap. Assume that the total number of resources for transmitting NR SLSS within Q2 sidelink synchronization resources for NR is Q2 _SLSS The resources used for SLSS in the above embodiment are Q1 subframes and Q2 corresponding to the LTE target side link synchronization resource and the NR target side link synchronization resource _SLSS Time slots, or Q1 x 2 ^μ +Q2 _SLSS The number of time slots, mu is log ₂ (SCS/15 kHz), SCS is SCS of NR side link.

Further, the NR control node, e.g. the gNB, provides information of the target sidelink synchronization resources of the NR and the target sidelink synchronization resources of the LTE, and the terminal determines that the target sidelink synchronization resources comprise the target sidelink synchronization resources of the NR and the target sidelink synchronization resources of the LTE when determining the resources of the NR sidelink resource pool. Optionally, the terminal determines: the target sidelink synchronization resource of the NR and the target sidelink synchronization resource of the LTE do not belong to the NR sidelink resource pool, and/or the bit in the resource bitmap corresponding to the target sidelink synchronization resource of the NR and the target sidelink synchronization resource of the LTE is a second value, and/or the terminal ignores the bit in the resource bitmap corresponding to the target sidelink synchronization resource of the NR and the target sidelink synchronization resource of the LTE.

Example seven: target sidelink synchronization resource

The target side link synchronous resource is synchronous resource which belongs to the same BWP or carrier with the determined resource of the resource pool for side link transmission;

Specifically, when determining a resource belonging to the resource pool i of BWP j, the target sidelink synchronization resource is a SL synchronization resource of BWP j; for example, in determining the resource of the resource pool i of BWP j, if a bit corresponding to the available resource belongs to the sidelink synchronization resource of BWP j, the resource is not considered to belong to the resource of the resource pool for sidelink transmission. For another example, in determining the resource of the resource pool i of BWP j, if a bit=first value of an available resource and the resource corresponding to the bit does not belong to the target sidelink synchronization resource of BWP j', the resource is considered to belong to the resource of the resource pool for sidelink transmission.

Or when determining resources belonging to a resource pool i of BWP j in carrier k, the target side link synchronization resources are side link synchronization resources of all activated BWPs in carrier k;

for example, in determining the resource of the resource pool i of BWP j in carrier k, if a bit corresponding to the available resource belongs to the sidelink synchronization resource of BWP j' in carrier k, the resource is not considered to belong to the resource of the resource pool for sidelink transmission. In determining the resources of the resource pool i of BWP j in carrier k, for example, if a bit=a first value of the corresponding available resources and the resource corresponding to the bit does not belong to the sidelink synchronization resource of BWP j' in carrier k, the resource is considered to belong to the resource of the resource pool for sidelink transmission.

Or when determining the resource belonging to the resource pool i of BWP j in carrier k, the target side link synchronization resource is the side link synchronization resource of all BWPs in carrier k;

for example, in determining the resource of the resource pool i of BWP j in carrier k, if a bit=a first value of the available resource and the resource corresponding to the bit belongs to the sidelink synchronization resource of BWP j' in carrier k, the resource is considered not to belong to the resource for the resource pool transmission of sidelinks.

For example, the control node provides information about the target sidelink synchronization resource of LTE, such as the number of sidelink synchronization resources used for LTE SLSS transmission, where the target sidelink synchronization resource at least includes the target sidelink synchronization resource of LTE.

For example, the control node provides information about the target sidelink synchronization resource of the NR (e.g., the number of sidelink synchronization resources used for NR SLSS transmission and/or the number of resources used for transmission of NR SLSS within the sidelink synchronization resource), where the target sidelink synchronization resource includes the target sidelink synchronization resource of the NR in the above steps.

For example, the control node provides information of the target sidelink synchronization resource of the NR (e.g., the number of sidelink synchronization resources used for NR SLSS transmission and/or the number of resources used for transmission of NR SLSS within the sidelink synchronization resource) and information of the target sidelink synchronization resource of the LTE (e.g., the number of sidelink synchronization resources transmitted by LTE SLSS), where the target sidelink synchronization resource includes the target sidelink synchronization resource of the NR and the target sidelink synchronization resource of the LTE in the above steps.

Alternatively, the control node in the above embodiments may be an NR control node, such as a gNB or other NR network device.
