Description

一种资源分配方法、装置 技术领域
本申请涉及通信领域，尤其涉及一种资源分配方法及装置。
背景技术
机器类型通信(Machine Type Communication，MTC)，是指通过部署具有一定感知、计算、执行和通信能力的各种设备，获取物理世界的信息，通过网络实现信息传输、协同和处理，从而实现人与物、物与物的互联。目前长期演进(Long Term Evolution，LTE)的Rel(release)-12、Rel-13、Rel-14版本能够支持MTC业务。
LTE Rel-13中，能够支持MTC业务的终端(User Equipment，UE)是带宽降低低复杂度UE(Bandwidth-reduced Low-complexity UE，BL UE)或覆盖增强的UE(Coverage Enhancement UE，CE UE)，其最大可支持的发送及接收带宽是1.4MHz，或者一个窄带(Narrowband，NB)。一个窄带在频率上包含连续的6个物理资源块(Physical resource block，PRB)的频率宽度。为了使得MTC能够支持更高的数据速率，LTE Rel-14对MTC进行进一步增强，称进一步增强的机器类型通信(Further Enhanced Machine-Type Communication，FeMTC)。在LTE Rel-14，将进行MTC业务的UE能够支持的用于传输业务数据的带宽进行了扩展，即支持5MHz的物理上行共享信道(Physical Uplink Shared channel，PUSCH)带宽，支持5MHz或者20MHz的物理下行共享信道(Physical Downlink Shared channel，PDSCH)带宽。
现有LTE Rel-13在为BL UE或者CE UE进行资源分配时，只能指示系统带宽中具体的某一个窄带，及指示该窄带内的PRB分配。即分配资源的频率宽度不超过一个窄带，或者不超过1.4MHz。然而LTE Rel-14的MTC业务支持更大PUSCH和PDSCH带宽，需求分配资源的频率宽度可达5MHz或者20MHz，此时频率宽度超过一个窄带，现有的资源分配方案无法满足资源分配的需求。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
如图1所示，图1为本申请提供的技术方案的网络构架，该网络构架包括：基站(base station)和多个UE，其中，UE与基站之间通过无线方式连接，该无线方式包括但不限于LTE的无线接入方式等方式。其中UE可以为多个，为了描述的方便，这里以UE1、UE2、UE3、UE4、UE5、UE6区分，其中UE可以为MTC中的任意设备，例如：智能手机(UE5)、智能电视、智能打印机、智能电水壶、智能电表等等能够支持MTC业务的设备，各个UE之间也可以通过无线方式连接，如图1所示，UE5可以通过无线方式与UE4和UE6连接。在网络构架中，基站可以发送资源块分配信息给UE1～UE6中的一个或多个UE。此外，UE5也可以发送资源块分配信息给UE4和UE6中的一个或多个UE。
LTE Rel-13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覆盖增强模式A(CE mode A)，和用于较大覆盖增强程度的覆盖增强模式B(CE mode B)。图2-1表示了LTE Rel-13CE mode A时的上下行资源分配的指示方法。下行控制信息(Downlink Control Information，DCI)格式6-0A和6-1A分别采用
Figure PCTCN2017073993-appb-000001
和
Figure PCTCN2017073993-appb-000002
个比特指示在系统带宽中分配的一个窄带的窄带索引。系统带宽的频率范围内包含一个或者多个窄带。对系统带宽的频率范围内包含的窄带在按照频率升序或者降序进行编号，即为窄带索引。其中，
Figure PCTCN2017073993-appb-000003
表示上行系统带宽在频率上包含的PRB的个数，
Figure PCTCN2017073993-appb-000004
表示下行系统带宽在频率上包含的PRB的个数。后5个比特(b0-b4)用于指示在所指示的窄带内PRB的分配，后5个比特的指示方式采用起点结合长度的方式，指示连续的PRB分配(下行起点结合长度的资源分配方式为类型2Type 2资源分配方式，上行起点结合长度的资源分配方式为类型0Type 0资源分配方式)。对窄带在频率上包含的连续的6个PRB按照频率升序或者降序进行编号，即为窄带内的PRB索引。所述窄带内的PRB索引的取值范围是0～5。5比特的二进制数对应的资源指示值(Resource  Indication Value，RIV)表示窄带内的PRB的一个起始PRB索引和连续的PRB个数。所述起始PRB索引是窄带内的PRB索引。RIV值如图2-2所示。例如RIV值为20时表示所述起始PRB索引为2，连续PRB个数为4个，同理，RIV值为19时，表示所述起始PRB索引为1，连续PRB个数为4个。LTE Rel-13的DCI格式6-0A和6-1A的资源分配，只能指示系统带宽中具体的某一个窄带，及指示该窄带内的PRB分配，即分配资源的频率宽度不超过一个窄带，无法满足分配5MHz或者20MHz资源的需求。
参阅图3，图3为本申请一实施例提供的一种资源分配方法，该方法由网络设备与终端之间执行，该终端具体可以为：智能手机、平板电脑、计算机、智能电视、智能打印机、智能电水壶、智能电表设备等，该网络设备具体可以为：基站、智能手机、平板电脑、中继站等等设备，该方法如图3所示，包括如下步骤：

参阅图4，图4为本申请另一实施例提供的一种资源分配方法，该方法由网络设备与终端之间执行，该终端具体可以为：智能手机、平板电脑、计算机、智能电视、智能打印机、智能电水壶、智能电表设备等，该网络设备具体可以为：基站、智能手机、平板电脑、中继站等等设备。该方法以1/2个窄带，即3个PRB为资源分配的资源单位。采用起点结合长度的资源分配方式。本实施例的资源块分配信息不指示禁选资源。如图4所示，包括如下步骤：
步骤S401、网络设备向终端发送资源块分配信息，所述资源块分配信息用于指示所述网络设备分配的起始资源单位以及连续资源单位的个数，所述资源单位为1/2窄带；所述资源块分配信息指示的所述网络设备为所述终端分配的资源由所述网络设备从可选资源中选取，所述可选资源为从所有资源中删除禁选资源后的资源。
对于本实施例中所述资源块分配信息用于指示所述网络设备分配的起始资源单位以及连续资源单位的个数，所述资源单位为1/2窄带，所述资源块分配信息的每个二进制比特串对应的RIV值表示分配的起始1/2窄带的位置和分配连续1/2窄带的个数。分配的起始1/2窄带的位置可以是以窄带中包含的第一个PRB(窄带内的PRB索引是0的PRB)为起点的连续3个PRB，即一个窄带的前1/2；也可以是窄带中包含的第四个PRB(窄带内的PRB索引是3的PRB)为起点的连续3个PRB，即一个窄带的后1/2。设系统带宽中包含的窄带个数为N，分配1/2个窄带共有2N种分配方法，分配1/2*2即1个窄带共有2N-1种分配方法(可以从窄带内的PRB索引是3的PRB开始，跨窄带分配1个窄带，即分配的2个1/2窄带分别位于2个连续的窄带；或者分配N个窄带中的一个窄带)，分配3/2个窄带共有2N-2种分配方法，……，分配N-1/2 个窄带共有2种分配方法，分配N个窄带共有1种分配方法。所以以1/2个窄带为资源单位，指示分配的起始1/2窄带的位置和分配连续1/2窄带的个数总共有2N+(2N-1)+(2N-2)+……+2+1＝(2N+1)*N种分配方法，即所述所有资源总共有(2N+1)*N种分配方法。
以20MHz系统带宽为例，系统带宽中包含的窄带个数N是16，所述所有资源总共有528种分配方法。如果所述资源块分配信息指示的所述网络设备为所述终端分配的资源为所有资源，则指示所述528种分配方法需要10比特。然而，10比特总共有1024种取值状态，其中只有528种取值状态指示了资源分配，这样就存在较多没有用到的取值状态，没有有效利用资源块分配信息的比特，资源块分配信息的比特开销较大。所以本实施例中所述资源块分配信息指示的所述网络设备为所述终端分配的资源由所述网络设备从可选资源中选取，所述可选资源为从所有资源中删除禁选资源后的资源。仍以20MHz系统带宽为例，如果所述禁选资源有16种分配方法，则所述可选资源为从528种分配方法中删除16种后留下的512种分配方法，所述资源块分配信息需要9比特即能够指示所述可选资源的512种分配方法，节约了所述资源块分配信息的比特开销。
所述可选资源或者所述禁选资源需要以预先规定的方式设置在网络设备和终端内。所述预先规定的方式可以是协议规定。所述禁选资源具体可以为：从第一起始资源单位开始的连续P个资源单位。即从第一1/2窄带开始的连续P个1/2窄带。
可选的，所述第一起始资源单位包括每个窄带的前1/2个窄带且所述P等于1。即所述禁选资源是分配1/2个窄带，起始位置是窄带中包含的第一个PRB，即分配每个窄带的前1/2个窄带。总共有N种资源分配方法。以20MHz系统带宽为例，即16个窄带中每个窄带的前1/2个窄带均为禁选资源，总共有16种分配方法。
或者，所述第一起始资源单位包括每个窄带的后1/2个窄带且所述P等于1。即所述禁选资源是分配1/2个窄带，起始位置是窄带中包含的第四个PRB，即分配每个窄带的后1/2个窄带。总共有N种资源分配方法。以20MHz系统带宽为例，即16个窄带中每个窄带的后1/2个窄带均为禁选资源，总共有16种分配方法。
或者，所述第一起始资源单位包括每个窄带的后1/2个窄带，所述P等于2。即分配1个窄带，起始位置是窄带中包含的第四个PRB，即跨窄带分配1个窄带，有N-1种资源分配方法。以及所述第一起始资源单位还包括窄带索引是N/2-1的窄带的前1/2个窄带，所述P等于4。其中N表示系统带宽中包含的窄带的个数，N为偶数。即分配系统带宽中间的2个窄带，有1种分配方法。所述禁选资源总共有N种分配方法。以20MHz系统带宽为例，所述禁选资源总共有16种分配方法。
可选的，所述网络设备和所述终端通信的系统带宽包括：1.4MHz、3MHz、5MHz、10MHz、20MHz中的一种或多种。即当系统带宽是1.4MHz、3MHz、5MHz、10MHz、20MHz中的一种或多种时，存在所述禁选资源。此时，所述资源块分配信息为
Figure PCTCN2017073993-appb-000005
个比特。当所述网络设备和所述终端通信的系统带宽是其它系统带宽，不存在所述禁选资源。即所述可选资源为所有资源。此时，所述资源块分配信息为
Figure PCTCN2017073993-appb-000006
个比特。比如当所述网络设备和所述终端通信的系统带宽是15MHz时，不存在所述禁选资源。

步骤S402、终端根据所述资源块分配信息，确定网络设备分配的第一资源。
步骤S403、终端在所述第一资源向网络设备发送信息或接收网络设备发送的信息。
本申请实施例能够分配窄带内的资源和更大带宽的资源，提高了资源指示的灵活性，满足了支持更大业务数据带宽(大于1.4MHz)的UE的需求。本实施例提供的技术方案将所有资源分配成可选资源和禁选资源，限制从可选资源中选取分配的资源，从而实现资源的分配，节省了资源块分配信息的比特开销，对资源块分配信息比特的各种取值充分赋予了有效意义，有效的利用了资源块分配信息比特。
参阅图5，图5为本申请又一实施例提供的一种资源分配方法，该方法由网络设备与终端之间执行，该终端具体可以为：智能手机、平板电脑、计算机、智能电视、智能打印机、智能电水壶、智能电表设备等，该网络设备具体可以为：基站、智能手机、平板电脑、中继站等等设备。该方法以窄带，即6个PRB为资源分配的资源单位。采用起点结合长度的资源分配方式。本实施例的资源块分配信息不指示禁选资源。如图5所示，包括如下步骤：
步骤S501、网络设备向终端发送资源块分配信息，所述资源块分配信息用于指示所述网络设备分配的起始资源单位以及连续资源单位的个数，所述资源单位为窄带；所述资源块分配信息指示的所述网络设备为所述终端分配的资源由所述网络设备从可选资源中选取，所述可选资源为从所有资源中删除禁选资源后的资源。
对于本实施例中所述资源块分配信息用于指示所述网络设备分配的起始资源单位以及连续资源单位的个数，所述资源单位为窄带，所述资源块分配信息的每个二进制比特串对应的RIV值表示分配的起始窄带和分配连续的窄带的个数。设系统带宽中包含的窄带个数为N，分配1个窄带共有N种分配方法，分配2个窄带共有N-1种分配方法，……，分配N-1个窄带共有2种分配方法，分配N个窄带共有1种分配方法。所以以1个窄带为资源单位，指示分配的起始窄带和分配连续的窄带的个数总共有N+(N-1)+(N-2)+……+2+1＝(N+1)*N/2种分配方法，即所述所有资源总共有(N+1)*N/2种分配方法。
以20MHz系统带宽为例，系统带宽中包含的窄带个数N是16，所述所有资源总共有136种分配方法。如果所述资源块分配信息指示的所述网络设备为所述终端分配的资源为所有资源，则指示所述136种分配方法需要8比特。然而，8比特总共有256种取值状态，其中只有 136种取值状态指示了资源分配，这样就存在较多没有用到的取值状态，没有有效利用资源块分配信息的比特，资源块分配信息的比特开销较大。所以本实施例中所述资源块分配信息指示的所述网络设备为所述终端分配的资源由所述网络设备从可选资源中选取，所述可选资源为从所有资源中删除禁选资源后的资源。仍以20MHz系统带宽为例，如果所述禁选资源有8种分配方法，则所述可选资源为从136种分配方法中删除8种后留下的128种分配方法，所述资源块分配信息需要7比特即能够指示所述可选资源的128种分配方法，节约了所述资源块分配信息的比特开销。
所述可选资源或者所述禁选资源需要以预先规定的方式设置在网络设备和终端内。所述预先规定的方式可以是协议规定。所述禁选资源具体可以为：从第一起始资源单位开始的连续P个资源单位。即从第一窄带开始的连续P个窄带。
可选的，所述第一起始资源单位包括窄带索引是偶数的窄带且所述P等于1。即所述禁选资源是分配1个窄带，且分配的窄带是索引是偶数的窄带。总共有N/2种资源分配方法。以20MHz系统带宽为例，即16个窄带中索引是偶数的窄带均为禁选资源，总共有8种分配方法。
或者，所述第一起始资源单位包括窄带索引是奇数的窄带且所述P等于1。即所述禁选资源是分配1个窄带，且分配的窄带是索引是奇数的窄带。总共有N/2种资源分配方法。以20MHz系统带宽为例，即16个窄带中索引是奇数的窄带均为禁选资源，总共有8种分配方法。
或者，所述第一起始资源单位包括系统带宽中的所有窄带且所述P等于1。即所述禁选资源是分配系统带宽中的任一窄带。总共有N种资源分配方法。
可选的，所述网络设备和所述终端通信的系统带宽包括：3MHz、5MHz、10MHz、20MHz中的一种或多种。即当系统带宽是3MHz、5MHz、10MHz、20MHz中的一种或多种时，存在所述禁选资源。此时，所述资源块分配信息为
Figure PCTCN2017073993-appb-000008
个比特(禁选资源的分配方法有N/2种)或
Figure PCTCN2017073993-appb-000009
个比特(禁选资源的分配方法有N种)。当所述网络设备和所述终端通信的系统带宽是其它系统带宽，不存在所述禁选资源。即所述可选资源为所有资源。此时，所述资源块分配信息为
Figure PCTCN2017073993-appb-000010
个比特。比如当所述网络设备和所述终端通信的系统带宽是15MHz时，不存在所述禁选资源。

比如对于20MHz系统带宽，资源块分配信息的比特数是7，资源块分配信息的比特是b6b5b4b3b2b1b0。比特b2b1b0的8种状态用于指示分配1个窄带，并且只能分配奇数或者偶数索引的窄带。b6b5b4b3b2b1b0表示的十进制数-8＝RIV，用于指示大于一个窄带的资源分配。RIV的每个数值对应一个起始窄带的位置和分配的连续窄带的个数。
步骤S502、终端根据所述资源块分配信息，确定网络设备分配的第一资源。
步骤S503、终端在所述第一资源向网络设备发送信息或接收网络设备发送的信息。
本申请实施例能够分配窄带内的资源和更大带宽的资源，提高了资源指示的灵活性，满足了支持更大业务数据带宽(大于1.4MHz)的UE的需求。本实施例提供的技术方案将所有资源分配成可选资源和禁选资源，限制从可选资源中选取分配的资源，从而实现资源的分配，节省了资源块分配信息的比特开销，对资源块分配信息比特的各种取值充分赋予了有效意义，有效的利用了资源块分配信息比特。

在现有LTE系统中，对下行资源分配，起点结合长度的资源分配方式以PRB为粒度，为类型2 Type 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以PRB为粒度，为类型0 Type 0资源分配方式。实施例类似于现有LTE系统中Type 2或者Type 0的资源分配方式。所述资源块分配信息的每个二进制比特串对应的RIV值表示分配资源的起始PRB和分配连续的PRB的个数。
在本实施例中，所述所有资源为起始PRB是系统带宽内的任一PRB，分配连续的PRB的个数是1～系统带宽内的PRB个数中的一种。所述禁选资源为从第一起始资源单位开始的连续P个资源单位。
在一种具体方式中，实施例最多分配24个PRB。这种实施方式应用于PDSCH或者PUSCH的资源分配。
可选的，当所述网络设备和所述终端通信的系统带宽为10MHz、15MHz、20MHz，所述第一起始资源单位包括系统带宽中的所有PRB并且P大于24。可选的，当所述网络设备和所述终端通信的系统带宽是20MHz时，所述第一起始资源单位还包括系统带宽内的PRB索引是奇数或者偶数的PRB并且P等于1，以及所述第一起始资源单位还包括系统带宽内的PRB索引是X的PRB并且P等于2；其中，X取[0，99]中的26个不同值。

本申请一实施例还提供一种资源分配的方法，本实施例用于支持PDSCH或PUSCH带宽是5MHz的UE。在本实施例中，所述资源块分配信息用于指示分配的窄带，以及在所述分配的窄带内分配的PRB；存在所述资源块分配信息的比特的状态所指示的分配的窄带个数大于1，在所述分配的窄带中的每个窄带内分配的PRB都相同。本实施例的资源块分配信息不指示禁选资源。即所述资源块分配信息指示的所述网络设备为所述终端分配的资源由所述网络设备从可选资源中选取，所述可选资源为从所有资源中删除禁选资源后的资源。
所述资源块分配信息用于指示分配的窄带的具体方式一是所述资源块分配信息用于指示起始窄带索引，以及所述起始窄带之后的连续3个窄带中的每个窄带是否分配资源。若起始窄带索引是i，所述起始窄带之后的连续3个窄带是指窄带索引是i+1、i+2、i+3的3个窄带。
设系统带宽中包含N个窄带，索引分别是0～N-1。本实施例中所述起始窄带索引所有可能有N种。
指示所述起始窄带之后的连续3个窄带中的每个窄带是否分配资源的所有可能共有8种。默认起始窄带分配资源。具体方式一应用于例如PDSCH。
所述资源块分配信息用于指示分配的窄带的具体方式二是所述资源块分配信息用于指示起始窄带索引，以及分配窄带的个数。可以分配1～4个窄带。分配的窄带是从所述起始窄带索引表示的窄带开始的连续窄带。具体方式二应用于例如PUSCH。
所述资源块分配信息用于指示分配的窄带的具体方式三是所述资源块分配信息用于指示起始窄带索引以及从所述起始窄带开始的连续4个窄带中分配的窄带起点和个数。即在从起始窄带开始的连续4个窄带中，采用起点结合长度的指示方式，以窄带为粒度。共有4+3+2+1＝10种可能性。若起始窄带索引是i，所述从起始窄带开始的连续4个窄带是指窄带索引是i、i+1、i+2、i+3的4个窄带。
以上三种所述资源块分配信息用于指示分配的窄带的具体方式可以应用于任意系统带宽。特别的，以上三种所述资源块分配信息用于指示分配的窄带的具体方式应用于系统带宽＞5MHz。
当所述网络设备和所述终端通信的系统带宽为5MHz或者3MHz时，所述资源块分配信息用于指示分配的窄带的具体方式四是所述资源块分配信息用于指示系统带宽内的每个窄带是否分配。5MHz系统带宽有16种可能性；3MHz系统带宽有4种可能性。
当所述网络设备和所述终端通信的系统带宽为5MHz或者3MHz时，所述资源块分配信息用于指示分配的窄带的具体方式五是所述资源块分配信息用于指示分配窄带的个数。指示分配的窄带以索引是0的窄带为起始。5MHz系统带宽有4种可能性。3MHz系统带宽有2种可能性。

需要说明的是，在以上所述资源块分配信息用于指示分配的窄带的具体方式中，所列出的可能性是所有资源分配方法的可能性，并未删除禁选资源的分配方法。
所述资源块分配信息用于指示在所述分配的窄带内分配的PRB的具体方式一是所述资源块分配信息用于指示在窄带内分配的起始PRB和PRB个数。即采用起点结合长度的资源分配方式，以PRB为资源单位。类似现有DCI格式6-0A或6-1A窄带内的资源分配，所有资源分配方法共有21种。起始窄带以及起始窄带之后的连续3个窄带中每个窄带内的资源分配方法都相同。
所述资源块分配信息用于指示在所述分配的窄带内分配的PRB的具体方式二是当所述资源块分配信息所指示的分配的窄带个数M为1时，所述资源块分配信息用于指示在窄带内分配的起始PRB和PRB个数。即采用类似现有DCI格式6-0A或6-1A起点结合长度的窄带内的资源分配。当所述资源块分配信息所指示的分配的窄带个数M大于1时，所述资源块分配信息用于指示在所分配的窄带中索引最大或者最小的窄带内分配的PRB的个数，其余M-1个窄带内的PRB全部分配。其中索引最大或者最小的一个窄带内分配的PRB与其余窄带中分配的PRB构成连续的PRB。所述资源块分配信息用于指示在所述分配的窄带内分配的PRB的具体方式二应用于例如PUSCH。该具体方式二保证了分配的资源是连续的。
本实施例中，所述资源块分配信息用于指示分配的窄带，以及在所述分配的窄带内分配的PRB可以由不同的二进制比特串分别指示。也可以由一个二进制比特串对应的RIV值来表示所述分配的窄带和在所述分配的窄带内分配的PRB。
