示例一,资源周期、资源图样、资源位图
若资源配置信息包含一个资源周期时,资源周期=资源图样的时域大小*Z1,或,资源图样的周期*Z1。
例如资源图样为TDD图样,且只有一个TDD图样,其周期为10ms,则资源周期为10ms*Z1。再例如资源图样为TDD图样,且只有一个TDD图样,其时域大小为80个时隙,则资源周期为80*Z1个时隙。优选地,Z1=1。
若资源配置信息包含多个资源周期,每个资源周期为对应资源图样的时 域单元数目的整数倍,或者,资源配置信息包含1个资源周期,资源周期为多个资源周期之和的整数倍。
例如资源图样为TDD图样,且有2个TDD图样,其周期分别为3ms和2ms,则资源周期P1和P2分为3ms*Z2和2ms*Z2;或者资源周期为5ms*Z2。
再例如资源图样为TDD图样,且有2个TDD图样,其周期分别为6个时隙和4个时隙,则资源周期P1和P2分为6*Z2个时隙和4*Z2个时隙;进一步地,或者资源周期为10*Z2个时隙。优选地,Z2=1。
c)可选地,资源周期为旁链路同步信号(SideLink Synchronization Signal,SLSS)周期*Z3或旁链路-同步信号块(SideLink-Synchronization Signal Block,S-SSB)周期*Z3,该周期的单位可以是毫秒(ms)或时隙(slot)。例如SLSS周期为160ms,则资源周期为160ms*Z3;再例如子载波SCS=30kHz时,S-SSB周期为320时隙,从而资源周期也可以表示为320*Z3个时隙。优选地,Z3=1。
其中,上述Z1、Z2、Z3为正整数。
若资源配置信息包含两个资源图样,资源指示信息包含1个或两个资源位图;若包含2个资源位图时,可选地,资源位图1的长度L1为资源图样1对应的ms数目的整数倍或者时隙数目的整数倍;可选地,资源位图2的长度L2为资源图样2对应的ms数目的整数倍或者时隙数目的整数倍。

若资源配置信息包含一个资源周期P1,资源指示信息包含一个资源位图;可选地,资源位图的长度L1为P1对应的ms数目的整数倍或者时隙数目的整数倍(或者理解为是P1的整数倍)。
示例二,可用资源和资源位图的比特位的对应关系计算方式
资源配置信息指示的第一资源中的可用资源和资源位图中的至少部分bit对应,对应方式包含:
a)资源位图的低A个bit或者高A个bit,和可用资源对应,A为可用资源的数目;
例如位图为80bit,A=20,则80bit中的低20bit和可用资源对应,或者80bit中的高20bit和可用资源对应。
b)若有两个资源位图,位图1的低A1个bit或者高A1个bit,和/或,位图2的低A2个bit或者高A2个bit,分别和可用资源对应,A1/A2为可用资源的数目。
例如,位图1为80bit,A1=20,位图2为80bit,A2=40,则:
位图1中的低20bit,或者,位图1中的高20bit,和可用资源对应;
和/或,位图2中的低40bit,或者,位图2中的高40bit,和可用资源对应。
示例三,可用资源和资源位图的比特位的对应关系计算方式
资源配置信息指示的第一资源中的可用资源和资源位图中的至少部分bit对应,对应方式包含:
a)资源位图的第B1+(P1+P2)*n+1到第B1+(P1+P2)*n+A1个bit,B2+P1+(P1+P2)*n+1到第B2+P1+(P1+P2)*n+A2个bit和可用资源对应;n=0…period/(P1+P2)-1,其中资源周期包含两个资源周期P1和P2,A1,A2为P1,P2内的可用资源数目,B1,B2为P1,P2内的不可用资源数目,period为资源位图周期或者长度。
例如,period=160ms;P1=P2=10ms;B1=5;A1=5;B2=2;A2=8,资源位图长度为160,则资源位图第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的比特位和可用资源对应。
b)资源指示信息包含两个资源位图,资源位图1的第B1+(P1+P2)*n+1到第B1+(P1+P2)*n+A1个bit,和/或,资源位图2的B2+P1+(P1+P2)*n+1到第B2+P1+(P1+P2)*n+A2个bit和可用资源对应;n=0…period/(P1+P2)-1, 其中资源周期包含两个资源周期P1和P2,A1,A2为P1,P2内的可用资源数目,B1,B2为P1 P2内的不可用资源数目,period为资源位图周期或者长度。
例如,period=160ms;P1=P2=10ms;B1=5;A1=5;B2=;A2=8,资源位图1长度为160,资源位图2长度为160,则位图1的第6~10,26~30,46~50,66~70,86~90,106~110,126~130,146~150的比特位,位图2的第12~20,32~40,52~60,72~80,92~100,112~120,132~140,152~160的比特位和可用资源对应。
c)资源位图的第B1+P1*n+1到第B1+P1*n+A1的比特位和可用资源对应;n=0…(period/P1-1),其中资源周期包含1个周期P1,A1为P1内的可用资源数目,B1为P1内的不可用资源数目,period为资源位图周期或者长度。
例如,period=160ms;P1=20ms;B1=15;A1=5,资源位图长度为160,则资源位图第16~20,36~40,56~60,76~80,96~100,116~120,136~140,156~160的比特位和可用资源对应。
示例四:第一资源包含的资源和资源位图的比特位对应
资源配置信息指示的资源和资源位图中的bit对应可能有:配置信息指示的每U个时隙和资源位图中的bit对应;
优选地,U=1。
可选地,如果进行SL通信或传输的频率位于FR1,则U=2。
可选地,如果进行SL通信或传输的频率位于FR2,则U=4。
可选地,U为资源配置信息配置的精度的整数倍;例如资源配置信息指示资源的精度为8个时隙,则U=8;例如资源配置信息指示资源的精度为4个时隙,则U=4;例如资源配置信息指示资源的精度为2个时隙,则U=2;例如资源配置信息指示资源的精度为1个时隙,则U=1。具体地,例如资源配置信息为SL-TDD-Config,且在SL-TDD-Config指示资源时的精度为2时隙,或者SL-TDD-Config指示的资源数目为2个时隙的倍数,或者SL-TDD-Config在可以指示的资源数目之间的最小差为2个时隙时,U=2。
上述说明中资源配置信息配置的精度为G,可以解释为资源配置信息指 示的资源数目为G的倍数,或者也可以解释为资源配置信息可以指示的资源数目之间的最小差为G。所述精度为G可以是G个时隙或者G个毫秒。
可选地,U=2 μ;μ=log 2(SCS/A),SCS为旁链路的子载波间隔,A为参考子载波间隔,例如A=15kHz或30kHz或60kHz。若A=15kHz,即资源配置信息指示的每个ms和资源指示信息中的bit对应。例如SL SCS=30kHz,则U=2 μ=2 1=2,此时每2个时隙分别和资源位图中的一个bit对应。
示例五
1.终端获取资源配置信息和资源指示信息,对资源配置信息指示的第一资源{S}应用资源指示信息;
2.资源配置信息指示的第一资源(记为集合{S})中的资源和资源位图的比特位存在对应关系。
3.终端根据资源指示信息确定用于旁链路传输的资源池的资源,具体包含以下至少一项:
a)若某个或某些比特位对应的是可用资源,如该比特位=第一值且该资源不属于旁链路同步资源,则对应的可用资源为用于旁链路传输的资源池的资源;
b)若某个或某些比特位对应的是下行资源,灵活资源,包含上行符号但是没有满足预设要求的资源,属于旁链路同步资源(即为用于SLSS传输的资源)中的至少一项时,用户忽略这些比特位。
具体地,一个旁链路传输占据一个时隙中的符号0-12,资源指示信息包含一个长度为80的bitmap,其中前59个bit对应下行时隙,第60个bit对应的时隙的前10个符号为flexible符号(灵活符号),后4个符号为上行符号,最后20个bit对应20个上行时隙。假设资源指示信息对应的80个时隙内的后20个时隙为可用时隙。
终端确定用于旁链路传输的资源池的资源时,忽略bitmap中的前60个bit,对于后20个bit,如果某个或者某些bit对应的时隙用于SLSS传输,则用户也忽略这些bit。对剩余的可用时隙,若其对应bit=1,则认为该时隙的资源属于用于旁链路传输的资源池(可称为旁链路资源池)的资源。
例如,假设后20个时隙对应的bit取值为1111 0000 0000 1111,且最后 一个时隙用于SLSS,则后20个时隙中的第1~4个时隙,和第13~15个时隙属于旁链路资源池。

如果一个时隙l j是一个可用时隙(例如是一个上行时隙),或者是一个满足预设要求的时隙,且对应的bit b j=1则该时隙属于用于旁链路传输的资源池的资源;
如果一个时隙l j是一个下行时隙,或是一个灵活时隙或者是一个用于SLSS的资源或者不满足预设要求,则该时隙不属于用于旁链路传输的资源池的资源。
