Description
本公开涉及通信技术领域,特别涉及一种资源分配的方法、装置及设备。
随着通信技术的发展,长期演进(LTE,Long Term Evolution)***的应用越来越广泛,其一种应用是用于MTC(Machine Type Communication,机器类型通信)。在LTE***里,物理信道中的数据可以通过PRB(Physical Resource Block,物理资源块)进行传输,PRB在频域上对应12个连续的子载波、在时域上对应一个时隙(即半个子帧)。其中,一个窄带在频域上包含6个PRB的频率宽度。在LTE的Rel-13版本中,能够支持MTC业务的终端设备是BL UE(Bandwidth-reduced Low-complexity User Equipment,带宽降低低复杂度终端设备)或CE UE(Coverage Enhancement User Equipment,覆盖增强的终端设备),其最大可支持的发送及接收带宽是1.4MHz,即只能接受和发送一个窄带之内的数据。LTE的Rel-13版本为CE UE提供了两种覆盖增强模式,即用于较小覆盖增强程度的CE mode A(Coverage Enhancement mode A,覆盖增强模式A),和用于较大覆盖增强程度的CE mode B(Coverage Enhancement mode B,覆盖增强模式B)。
网络设备和终端设备在进行数据传输前,网络设备会先为终端设备分配用于传输数据的物理资源。所述物理资源包括一个或者多个PRB。网络设备可以先确定用于该终端设备数据传输的窄带(为了便于描述,可称为目标窄带),然后在目标窄带所包括的6个PRB中,选择为终端设备分配的PRB。网络设备可以确定目标窄带的索引信息,并可以根据从目标窄带选择的PRB,确定窄带内PRB的分配信息。其中,窄带内PRB的分配信息可以为3个比特。例如,用0-5来标识窄带中的6个PRB,窄带内PRB的分配信息的比特状态000对应0,001对应1,010对应2...110对应0和1,111对应2和3,如果网络设备为终端设备分配的PRB为0和1,则可以确定窄带内PRB的分配信息的比特的状态为110。网络设备可以向终端设备发送资源分配信息,资源分配信息中可以包括确定出的索引信息和窄带内PRB的分配信息。终端设备中也存储有上述资源分配规则,然后根据该资源分配信息的比特的状态,确定对应的PRB,基于确定出的PRB进行数据传输。
为了使得MTC能够支持更高的数据速率,在LTE的Rel-14版本,将进行MTC业务的终端设备能够支持的用于传输数据的带宽进行了扩展。在CE mode B,BL UE和non-BL UE(non-Bandwidth-reduced Low-complexity UE,非带宽降低低复杂度UE)支持的PUSCH(Physical Uplink Shared channel,物理上行共享信道)带宽仍保持1.4MHz。然而,对于PDSCH(Physical Downlink Shared channel,物理下行共享信道),BL UE支持的最大数据带宽扩展到5MHz,non-BL UE支持的PDSCH的数据带宽可以是1.4MHz,5MHz或者20MHz。另外,在LTE***中,网络设备所支持的***带宽也可以是多种多样的,如1.4MHz、3MHz、5MHz、10MHz、15MHz和20MHz等。
在实现本公开的过程中,发明人发现现有技术至少存在以下问题:
在分配物理资源时,网络设备只能在一个窄带内为终端设备分配物理资源,终端设备和网络设备之间只能在一个窄带内的物理资源上传输数据,导致传输数据的效率较低,无法满足进行MTC业务的终端设备更高的数据速率要求。

为了满足进行MTC业务的终端设备更高的数据速率要求,本实施例提供了一种资源分配的方法,该方法可以由网络设备执行,如图4所示,该方法的处理流程可以如下:
步骤401,网络设备向终端设备发送资源分配信息。
在实施中,可以设置PRB索引、窄带索引和宽带索引。网络设备的***带宽内的PRB可以按频率升序(或降序)进行编号,每个PRB的编号即为该PRB的PRB索引。记索引是n的PRB是PRBn。***带宽内的窄带也可以按频率升序(或降序)进行编号,每个窄带的编号即为该窄带的窄带索引。记索引是i的窄带为NBi。NBi在频率上可以包含物理资源块PRBn,PRBn+1,PRBn+2,PRBn+3,PRBn+4,PRBn+5,其中,PRBn是窄带NBi中索引值最小的PRB,也称第一个PRB。***带宽内的宽带也可以按频率升序(或降序)对每一个宽带进行编号,每一个宽带的编号即为该宽带的宽带索引。记索引是j的宽带为WBj。WBj在频率上可以包含窄带NBi,NBi+1,NBi+2,NBi+3,其中,NBi为宽带WBj中索引值最小的窄带。例如,对于20MHz***带宽,窄带索引是0~15,PRB索引是0~99,宽带索引是0~3。其中,n、i、j均为非负整数。
上述索引指示信息可以指示分配的起始窄带时,具体的实现方式可以包括以下几种。
(1)索引指示信息可以用于指示窄带索引,窄带索引是X的倍数,X的取值为4、2、1中的一个,起始窄带是窄带索引所表示的窄带。
在实施中,索引指示信息的比特状态可以指示窄带索引。例如,对于20MHz***带宽,X的取值为4,索引指示信息需要指示的窄带索引为0、4、8和12中的一个,则索引指示信息可以为2比特,包括4种不同的比特状态,分别指示0、4、8和12,此时,起始窄带可以
为NBi,i为0、4、8、12中的一个。类似的,如果X的取值为2,索引指示信息可以为3比特,用于指示窄带索引为0、2、4、6、8、10、12、14中的一个,起始窄带可以为NBi,i为0、2、4、6、8、10、12、14中的一个。
(2)索引指示信息用于指示物理资源块PRB索引,PRB所在的窄带的索引是X的倍数,X的取值为4、2、1中的一个,起始窄带是PRB索引所表示的PRB所在的窄带。
在实施中,索引指示信息的比特状态可以指示PRB索引。例如,对于10MHz***带宽,X的取值为4,***带宽中的窄带的索引是0~7,索引指示信息需要指示的PRB索引为1和25中的一个,则索引指示信息为1比特,包括2种不同的比特状态,分别指示1和25中的一个,此时,起始窄带可以为NBi,i为0和4中的一个。
(3)索引指示信息用于指示宽带索引,起始窄带是宽带索引所表示的宽带所包含的窄带中,索引值最小的窄带。
在实施中,索引指示信息的比特状态可以指示宽带索引。例如,对于20MHz***带宽,索引指示信息需要指示的宽带索引为0、1、2和3中的一个,索引指示信息为2比特,包括4种不同的比特状态,分别指示0、1、2和3中的一个,此时,起始窄带可以为NBi,i为0和4、8或12中的一个。
索引指示信息可以是个比特,其中,可以表示***带宽在频率上包含的PRB的个数。例如,***带宽为20MHz,X取值为4,则索引指示信息可以是2比特;***带宽为10MHz,X取值为4,则索引指示信息可以是1比特。不同***带宽下,X的各取值所对应的索引指示信息的比特数可以参见表8。
下面对窄带分配信息进行说明。
在实施中,窄带分配信息可以为2比特或3比特,窄带分配信息的比特状态可以用于指示分配的物理资源是在1个窄带内,还是大于1个窄带。当指示1个窄带内的资源分配时,该窄带可以是所述起始窄带。当指示大于1个窄带的资源分配时,窄带分配信息可以指示从所述起始窄带开始的连续G个窄带内的资源分配,G可以为正整数且不超过4或16。
窄带分配信息指示大于一个窄带内的资源分配时,可以存在以下几种情况:
(1)窄带分配信息的比特数可以是3,该窄带分配信息所分配的物理资源可以包括(NBi,NBi+1)、(NBi,NBi+2)、(NBi,NBi+3)、(NBi+1,NBi+2)、(NBi+1,NBi+3)、(NBi+2,NBi+3)、(NBi,NBi+1,NBi+2)、(NBi+1,NBi+2,NBi+3)、(NBi,NBi+1,NBi+3)、(NBi,NBi+2,NBi+3)、(NBi,NBi+1,NBi+2,NBi+3)中的一种或多种。
其中,NBi为起始窄带;NBi、NBi+1、NBi+2和NBi+3可以是连续的4个窄带。
该情况可以适用于***带宽大于3MHz,终端设备的数据带宽等于5MHz的场景,3比特指示分配的物理资源最多是4个窄带,即24个PRB或者一个宽带。此时,资源分配信息的比特状态所分配的资源块个数小于或等于24个。G不超过4。
(2)窄带分配信息的比特数是3,窄带分配信息所分配的物理资源包括WBj、(WBj,WBj+1)、(WBj+1,WBj+2)、(WBj+2,WBj+3)、(WBj,WBj+1,WBj+2)、(WBj+1,WBj+2,WBj+3)、(WBj,WBj+1,WBj+2,WBj+3)中的一种或多种。或者,窄带分配信息所分配的物理资源包括WBj、(WBj,WBj+1)、(WBj,WBj+2)、(WBj,WBj+3)、(WBj,WBj+1,WBj+2)、(WBj,
WBj+1,WBj+3)、(WBj,WBj+2,WBj+3)、(WBj,WBj+1,WBj+2,WBj+3)中的一种或多种。
其中,WBj表示由窄带NBi、NBi+1、NBi+2、NBi+3组成的宽带;WBj+1表示由窄带NBi+4、NBi+5、NBi+6、NBi+7组成的宽带;WBj+2表示由窄带NBi+8、NBi+9、NBi+10、NBi+11组成的宽带;WBj+3表示由窄带NBi+12、NBi+13、NBi+14、NBi+15组成的宽带;NBi为起始窄带;窄带NBi~NBi+15是连续的窄带;WBj,WBj+1,WBj+2,WBj+3是连续的宽带。
该情况可以适用于***带宽为20MHz,终端设备的数据带宽等于20MHz的场景,3比特指示分配的物理资源最多是16个窄带,即96个PRB或者4个宽带。此时,资源分配信息的比特状态所分配的资源块个数小于或等于96个。G不超过16。
(3)窄带分配信息的比特数是2,窄带分配信息所分配的物理资源包括(NBi,NBi+1)。
其中,NBi为起始窄带;NBi、NBi+1是连续的2个窄带。
该情况可以适用于***带宽为3MHz的场景,2比特指示分配的物理资源最多是2个窄带。
其中,上述几种情况中,窄带分配信息所分配的物理资源还可以包括(PRBn,PRBn+1,PRBn+2,PRBn+3)和/或NBi。其中,NBi为起始窄带,(PRBn,PRBn+1,PRBn+2,PRBn+3)是NBi包含的PRB中索引最小的4个PRB。这样,窄带分配信息也可以指示分配窄带内4个PRB、分配整个窄带的物理资源,这样与LTE的Rel-13版本的DCI(Downlink Control Information,下行控制信息)格式6-1B的资源分配兼容。这样,当分配的物理资源是一组终端设备的物理资源时,比如分配随机接入响应(Random Access Response,RAR)的资源时,可以给支持更大数据带宽(大于1.4MHz)的UE和支持1.4MHz数据带宽的UE分配相同的物理资源,避免给不同带宽能力的UE发送多套资源,提高了资源利用的效率。
本实施例提供了在几种不同场景下,窄带分配信息指示资源分配的示例,具体如下。
对于上述情况(1),窄带分配信息分配的窄带可以是连续的,如表1所示:
表1
在表1中,前两种比特状态可以指示分配的物理资源是在窄带内,分别指示分配4个PRB还是分配了整个窄带(即6个PRB)。后6种状态指示分配的物理资源大于1个窄带。可以指示分配了连续的2个、3个或者4个窄带。表2的资源分配指示最多可指示分配4个窄带,即24个PRB或者一个宽带的资源。表2的资源分配指示可以指示分配4个PRB、分配1个窄带的物理资源,这样可以与LTE的Rel-13版本的DCI格式6-1B的资源分配兼容。
对于上述情况(1),窄带分配信息分配的窄带可以是连续的,也可以是不连续的,如表
2所示:
表2
在表2中,前两种比特状态可以指示分配的物理资源是在窄带内,分别指示分配4个PRB还是分配了整个窄带(即6个PRB)。后6种状态指示分配的资源大于1个窄带。可以指示分配了2个、3个或者4个窄带。当指示分配了2个、3个窄带时,这些窄带可以是连续的,也可以是不连续的。表2的资源分配指示最多可指示分配4个窄带,即24个PRB或者一个宽带的物理资源。表2的资源分配指示可以指示分配4个PRB、分配1个窄带的物理资源,这样可以与LTE的Rel-13版本的DCI格式6-1B的资源分配兼容。
对于上述情况(2),窄带分配信息分配的窄带可以是连续的。窄带分配信息所分配的物理资源包括WBj、(WBj,WBj+1)、(WBj+1,WBj+2)、(WBj+2,WBj+3)、(WBj,WBj+1,WBj+2)、(WBj+1,WBj+2,WBj+3)、(WBj,WBj+1,WBj+2,WBj+3)中的一种或多种。例如表3所示:
表3
在表3中,WBj表示以NBi为起始窄带的连续4个窄带,即窄带NBi、NBi+1、NBi+2、NBi+3;WBj+1表示以NBi+4为起始窄带的连续4个窄带,即窄带NBi+4、NBi+5、NBi+6、NBi+7;WBj+2表示以NBi+8为起始窄带的连续4个窄带,即窄带NBi+8、NBi+9、NBi+10、NBi+11;WBj+3表示以NBi+12为起始窄带的连续4个窄带,即窄带NBi+12、NBi+13、NBi+14、NBi+15。当3bit的状态是000时,指示分配了4个PRB,或者指示了分配整个窄带的物理资源。表3的资源分配指示最多可指示分配16个窄带,即96个PRB或者4个宽带的物理资源。表3的资源分配包含了4个PRB或1个窄带(6个PRB)的分配,这样可以与Rel-13的资源分配兼容。
窄带分配信息分配的窄带还可以如表4所示。
表4
在表4中,当3bit的状态是000时,指示分配了4个PRB,或者指示了分配整个窄带的物理资源;当3bit的状态是001时,指示分配了两个连续的窄带,其中,NBi和NBi+1可以是WBj中索引值最小的两个窄带。后6种状态指示分配的物理资源大于或等于1个宽带。
对于上述情况(2),窄带分配信息分配的窄带可以是连续的,也可以是不连续的,窄带分配信息所分配的物理资源包括WBj、(WBj,WBj+1)、(WBj,WBj+2)、(WBj,WBj+3)、(WBj,WBj+1,WBj+2)、(WBj,WBj+1,WBj+3)、(WBj,WBj+2,WBj+3)、(WBj,WBj+1,WBj+2,WBj+3)中的一种或多种。当分配8个窄带时,比特的状态指示的资源分配包含(WBj,WBj+1)、(WBj,WBj+2)、(WBj,WBj+3)中的一种或多种。当分配12个窄带时,3比特的状态指示的资源分配包含(WBj,WBj+1,WBj+2)、(WBj,WBj+1,WBj+3)、(WBj,WBj+2,WBj+3)中的一种或多种。窄带分配信息分配的窄带还可以如表5或表6所示:
表5
表6
对于上述情况(3),窄带分配信息分配的窄带可以如表7所示:
表7
在表7中,窄带分配信息最多可指示分配2个窄带,即12个PRB的物理资源。表7的资源分配可以应用于支持数据带宽5MHz的终端设备,也可以应用于支持数据带宽20MHz的终端设备。表7的资源分配指示可以指示分配窄带内4个PRB、分配整个窄带的物理资源,这样与LTE的Rel-13版本的DCI格式6-1B的资源分配兼容。
在方式一中,资源分配信息的比特个数可以如表8所示:
表8
需要说明的是,在方式一中,对于支持数据带宽20MHz的终端设备,当***带宽小于20MHz且大于3MHz时,若窄带分配信息的比特状态中,某比特状态所指示的窄带索引,超过了***带宽内窄带索引的最大值,则该窄带分配信息无效。
或者,对于支持数据带宽20MHz的终端设备,当***带宽小于20MHz且大于3MHz时,若窄带分配信息的比特状态中,某比特状态所指示的窄带索引,超过了***带宽内窄带索引的最大值,则在该窄带分配信息指示的窄带的索引中,不超过***带宽内窄带索引的最大值的索引值表示的窄带是有效的。
可选的,可以根据网络设备的***带宽,来确定X的取值。当网络设备的***带宽是第一***带宽时,窄带索引或PRB所在的窄带的索引是X1的倍数;当网络设备的***带宽是第二***带宽时,窄带索引或PRB所在的窄带的索引是X2的倍数。
或者,可以根据终端设备支持的数据带宽,来确定X的取值。当终端设备支持的数据带宽是第一数据带宽时,窄带索引或PRB所在的窄带的索引是X1的倍数;当终端设备支持的数据带宽是第二数据带宽时,窄带索引或PRB所在的窄带的索引是X2的倍数。
其中,第一***带宽大于第二***带宽;第一数据带宽大于第二数据带宽,X1大于X2,X1、X2的取值分别是4、2、1中的一种。
基于上述处理,对于较大的***带宽,可以采用较大粒度的分配方式;对于较小的***带宽,可以采用较小粒度的分配方式。同样,对于较大的数据带宽,可以采用较大粒度的分配方式;对于较小的数据带宽,可以采用较小粒度的分配方式。这样,可以使分配的粒度与当前的***带宽或网络带宽相匹配,提高资源分配的合理性。
基于方式一,网络设备可以先确定为终端设备分配的起始窄带,以及从起始窄带开始的连续G个窄带,然后可以从连续G个窄带中,确定为终端设备分配的物理资源。网络设备可以根据为终端设备分配的物理资源包含的起始窄带,确定索引指示信息,并可以根据从连续G个窄带中分配的物理资源,确定窄带分配信息的比特状态,进而根据确定出的索引指示信息和窄带分配信息,得到资源分配信息的比特状态。
方式二、资源分配信息的比特数小于或等于5,资源分配信息的比特的数目与窄带组NBG的数目相同,资源分配信息的每个比特对应一个NBG,每个比特的两种状态表示对应的NBG所包含的物理资源是否分配。
在实施中,可以对***带宽内的窄带进行分组,得到至少一个窄带组(Narrowband Group,NBG)。其中,一个NBG可以包含至少一个窄带。方式二中,是以NBG为粒度,采取比特映射的方式进行资源分配。资源分配信息的比特个数可以与划分的NBG的数目相同,每个
NBG可以映射到一个比特,该比特的两种比特状态,可以指示对应的NBG是否被分配。例如,比特状态0可以指示对应的NBG没有被分配,比特状态1可以指示对应的NBG被分配。若分配了某一个NBG,则是分配了该NBG内的所有PRB。方式二中,任意两个NBG包含的窄带个数相差最大不超过1。
不同的***带宽下,NBG的划分方式可以如表9所示:
表9
其中,NBG的划分示例所对应的数字,表示的是每个NBG包含的窄带的个数。
例如,对于20MHz***带宽,3,3,3,3,4表示共划分5个NBG,前4个NBG中的每个NBG包含3个窄带,后一个NBG包含4个窄带,即第一个NBG包含的窄带的索引为0~2,第二个NBG包含的窄带的索引为3~5,第三个NBG包含的窄带的索引为6~8,第四个NBG包含的窄带的索引为9~11,第五个NBG包含的窄带的索引为12~15;
对于15MHz***带宽,2,2,2,3,3表示共划分5个NBG,前3个NBG中的每个NBG包含2个窄带,后2个NBG中的每个NBG包含3个窄带,即第一个NBG包含的窄带的索引为0~1,第二个NBG包含的窄带的索引为2~3,第三个NBG包含的窄带的索引为4~5,第四个NBG包含的窄带的索引为6~8,第五个NBG包含的窄带的索引为9~11;对于10MHz***带宽,2,2,2,2表示共划分4个NBG,每个NBG包含2个窄带;
对于5MHz***带宽,1,1,2表示共划分3个NBG,前2个NBG中的每个NBG包含1个窄带,后1个NBG包含2个窄带;
对于3MHz***带宽,1,1表示共划分2个NBG,每个NBG包含1个窄带。
这种实施方式采用的资源分配比特个数和LTE的Rel-13版本的DCI格式6-1B的资源分配相同。这种实施方式可以应用于支持数据带宽是20MHz的终端设备。当***带宽小于等于5MHz时,这种实施方式还可以应用于支持数据带宽是5MHz的终端设备。
基于方式二,网络设备可以先确定为终端设备分配的NBG,然后再确定资源分配信息中各比特的比特状态。
方式三、资源分配信息的比特数小于或等于5,资源分配信息用于指示分配的起始NBG以及连续NBG的个数Z。
在方式三的一种实施方式中,Z可以是小于等于K的正整数,K是***带宽中所有NBG的个数,并且任意两个NBG包含的窄带个数相差最大为1。
在实施中,可以对***带宽内的窄带进行分组,得到至少一个NBG。其中,一个NBG可以包含至少一个窄带。方式三中,是以NBG为粒度,采用起点结合长度的方式分配资源。记***带宽内NBG的个数为N,资源分配的比特个数为
在现有LTE***中,对下行资源分配,起点结合长度的资源分配方式为类型2Type 2资源分配方式,对于上行资源分配,起点结合长度的资源分配方式为类型0Type 0资源分配方式。本实施方式中,起点结合长度的资源分配方式与现有下行Type 2资源分配方式/上行Type0资源分配方式类似。不同的是资源分配的粒度是NBG。个比特的二进制数对应的资源指示值(Resource Indication Value,RIV)表示一个起始NBG和连续的NBG个数。表示的连续NBG的个数可以是1个NBG~***带宽中所有N个NBG中的一种。NBG的划分方式示例如表10所示:
表10
***带宽 | 3MHz | 5MHz | 10MHz | 15MHz | 20MHz |
***带宽包含的窄带个数 | 2 | 4 | 8 | 12 | 16 |
***带宽包含的NBG个数 | 2 | 3 | 5 | 7 | 7 |
NBG的划分示例一 | 1,1 | 1,2,1 | 1,2,2,2,1 | 1,2,2,2,2,2,1 | 3,2,2,2,2,2,3 |
NBG的划分示例二 | 1,1 | 1,2,1 | 2,1,2,1,2 | 2,2,1,2,1,2,2 | 2,2,3,2,3,2,2 |
资源分配的比特个数 | 2 | 3 | 4 | 5 | 5 |
其中,NBG的划分示例所对应的数字,表示的是每个NBG包含的窄带的个数。
例如,对于20MHz***带宽,3,2,2,2,2,2,3表示共划分7个NBG,第1个和第7个NBG中的每个NBG包含3个窄带,其余的NBG中的每个NBG包含2个窄带,即第一个NBG包含的窄带的索引为0~2,第二个NBG包含的窄带的索引为3~4,第三个NBG包含的窄带的索引为5~6,第四个NBG包含的窄带的索引为7~8,第五个NBG包含的窄带的索引为9~10,第六个NBG包含的窄带的索引为11~12,第七个NBG包含的窄带的索引为13~15;
对于15MHz***带宽,1,2,2,2,2,2,1表示共划分7个NBG,第1个和第7个NBG中的每个NBG包含1个窄带,其余的NBG中的每个NBG包含2个窄带;
对于10MHz***带宽,1,2,2,2,1表示共划分5个NBG,第1个和第5个NBG中的每个NBG包含1个窄带,其余的NBG中的每个NBG包含2个窄带;
对于5MHz***带宽,1,2,1表示共划分3个NBG,第1个和第3个NBG中的每个NBG包含1个窄带,第2个NBG包含2个窄带;
对于3Hz***带宽,1,1表示共划分2个NBG,每个NBG包含1个窄带。
这种实施方式采用的资源分配比特个数和LTE的Rel-13版本的DCI格式6-1B的资源分配相同。这种实施方式可以应用于支持数据带宽是20MHz的UE。当***带宽小于等于5MHz时,这种实施方式还可以应用于支持数据带宽是5MHz的UE。
基于方式三,网络设备可以先确定为终端设备分配的NBG,即确定分配的起始NBG以及连续NBG的个数Z,然后再确定资源分配信息中各比特的比特状态。
在方式三的另一种实施方式中,Z个连续NBG的带宽可以小于或等于5MHz,并且一个NBG包含1个或2个窄带。
在实施中,可以将***带宽内的窄带划分成至少一个NBG,用起点结合长度的方式分配资源。本实施方式中,起点结合长度的资源分配方式与现有下行Type 2资源分配方式/上行Type 0资源分配方式类似。不同的是资源分配的粒度是NBG。资源分配的比特的二进制数对应的资源指示值(Resource Indication Value,RIV)表示一个起始NBG和连续的NBG个数。表示的连续NBG的个数Z最小是1,最大需满足Z个NBG的频率宽度不超过5MHz。NBG的划分方式示例如表11所示:
表11
其中,NBG的划分示例对应的数字,表示的是每个NBG包含的窄带的个数。这种实施方式采用的资源分配比特个数和LTE的Rel-13版本的格式6-1B的资源分配相同。这种实施方式可以应用于支持数据带宽是5MHz的UE。

在实施中,终端设备获取到资源分配信息的比特状态后,可以根据预先存储的资源分配信息指示分配的物理资源的方式,确定接收到的资源分配信息的比特状态所指示的物理资源。
资源分配信息指示分配的物理资源的方式可以是多种多样的,本实施例提供了几种可行的处理方式,具体如下。
方式一,资源分配信息可以包括索引指示信息和窄带分配信息,索引指示信息可以用于指示分配的起始窄带,窄带分配信息可以用于指示从起始窄带开始的连续G个窄带内的资源分配,G为正整数且小于或等于16,如图5a所示,为资源分配信息的示意图,如图5b所示,为资源分配信息分配的物理资源的示意图,其中,***带宽为20MHz。
方式一的具体处理过程可以参照步骤401中的相关说明,此处不再赘述。
在方式一中,终端设备可以对资源分配信息进行解析,获取其中的索引指示信息和窄带分配信息,然后可以根据获取到的索引指示信息,确定对应的起始窄带,并可以根据获取到的窄带分配信息,确定从第一起始窄带开始的连续G个窄带,从连续G个窄带中,确定网络设备分配的物理资源。
方式二、资源分配信息的比特数小于或等于5,资源分配信息的比特的数目与窄带组NBG的数目相同,资源分配信息的每个比特对应一个NBG,每个比特的两种状态表示对应的NBG所包含的物理资源是否分配。
方式二的具体处理过程可以参照步骤401中的相关说明,此处不再赘述。
在方式二中,终端设备可以对资源分配信息进行解析,获取资源分配信息中每个比特的比特。终端设备可以确定每个比特对应的NBG,并根据该比特的比特状态,确定对应的NBG是否分配。这样,终端设备可以根据资源分配信息中各比特的状态,确定网络设备分配的NBG。
方式三、资源分配信息的比特数小于或等于5,资源分配信息用于指示分配的起始NBG以及连续NBG的个数Z。
方式三的具体处理过程可以参照步骤401中的相关说明,此处不再赘述。
在方式三中,终端设备可以对资源分配信息进行解析,获取资源分配信息中每个比特的
比特,根据每个比特的状态,确定起始NBG以及连续NBG的个数Z,确定出的NBG,即为网络设备分配的物理资源。
步骤603,终端设备在网络设备分配的物理资源上,向网络设备发送上行信息和/或接收网络设备发送的下行信息。
在实施中,终端设备确定网络设备分配的物理资源后,可以在该物理资源上,向该网络设备发送上行信息,并可以接收该网络设备发送的下行信息。
