Description

资源分配的方法、 系统和装置 本申请要求于 2008年 6月 24日提交中国专利局、 申请号为 200810068040.4、发明 名称为 "资源分配的方法、 系统和装置"的中国专利申请的优先权, 其全部内容通过引用 结合在本申请中。
技术领域
本发明涉及网络和通信技术, 尤其涉及资源分配的方法、 系统和装置。
发明背景
在现有系统中, 比如 LTE ( long term evolution,长期演进)系统中,网络将 UE (User Equipment, 用户设备)在上下行可采用的系统带宽通过广播信令通知给 UE, 比如下行 带宽通过 PBCH通知给 UE, 上行带宽通过 D-BCH通知给 UE。 UE根据检测到的资源分配 类型, 确定被分配的时频资源的位置, 利用该时频资源接收或发送数据。
其中, 资源分配类型对于网络侧和用户设备来说, 是确定的几种类型。 比如, 在 LTE系统中下行资源分配方法中, 资源分配类型包括 type 0、 type 1和 type 2。该资源分配 类型承载在控制信道中, 通过控制信令下发给 UE。
对于资源分配类型 type 0,采用 bitmap (比特映射)指示被调度 UE的 RBGs (Resource Block Groups, 资源块组) 资源, RBG是资源分配 typeO最小的资源分配粒度。 每个 RBG 的大小, 也就是一个 RBG包括的 RB (Resource Block, 资源块)个数, 是系统带宽的函 一所示。其中, 系统带宽用包含的最小 RB个数表示, 即 在资源分配指令
Figure imgf000003_0001
bits (比特)来指示若干个 RBGs时频资源的分配, 其中 P为 RBG的 大小, 也就是一个 RBG包括的 RB个数。 由于不同的系统带宽对应的 P值不同, 也就是资 源分配的最小粒度不同, 所以在不同带宽情况下, 资源分配信息所占用的比特数目会比 较接近, 不会因为系统带宽的增加而线性 。
Figure imgf000003_0002
Figure imgf000003_0003
在同一系统带宽下, 资源分配类型 type 1和 type 0所占的比特数目是一样的。 但是 对于具体采用多少个比特数来指示被调度给 UE的资源, type 1和 type 0是不同的。 比如, 如果 type 0中每个 RBG包括 P个 RB , type 1将会把系统带宽分成 P个资源块组子集
(Resource Block Group Subsets)。所以需要「 g2(P),个比特指示被调度给 UE的时频资源 在哪个资源块组子集中, 同时, 为了能指示尽量多的资源, 还有 lbit用于指示资源分配 的起始方向, 既是从左还是从右进行 bitmap指示资源分配的。所以用于指示被调度给 UE 资源的比特数为 ^ Μ ' ' 1 。不同系统带宽对应的资源块组子集的个 数不同, 被调度给一个 UE的资源分配在一个资源块组子集中进行, 所以在不同的系统 带宽情况下,资源分配类型 typel中资源分配信息所占用的比特数也是比较接近的,不会 因为系统带宽的增加而线性增加。资源分配类型 type 1和 type 0的资源分配信令所占用的 比特数目是一样的,为了区分调度的 UE资源分配类型是 type 1还是 type O,在时间传输单 元对应的控制信道中还需要 lbit用于区分资源分配类型 type 1和 type 0。
在同一系统带宽下, Type 2资源分配信令使用的比特数与 type 0和 type l不同, 具体 资源分配方式也不同。 具体的, 资源分配信息中需要 1个比特表示是连续分配的 PRBs (physical resource blocks, 物理资源块)还是 VRBs (virtual physical resource blocks* 虚 拟资源块)。 PRB分配是可以从单个 PRB到最大的 PRBs个数, 可包括整个系统带宽内的 所有资源块。 对于 VRB分配, 资源分配信息中包括起始 VBR序号和连续的几个 VRBs, 但每个 V B映射到多个不连续的 PRB s。
由于同一系统带宽下, 资源分配类型 type 0、 type l和 type 2的信息长度并不完全相 同, UE通过盲检测资源分配的信息长度及信息内容, 进而来获取具体的资源分配类型。
而在未来的通信系统中, 比如 LTE-A系统, 支持更宽的带宽。 可以将多个载波 的资源同时调度给一个 UE使用, 或者可以将一个系统的载波带宽扩展到更宽的带宽。 未来的通信系统中, 会比较灵活的形成一定大小的系统带宽。 比如, 达到 20M带宽, 可 能是连续的 20M带宽, 也可能是连续的 2个 10M频谱的聚合, 或是离散的 2个 10M频谱的 聚合, 或是 2个 5M和 1个 10M频谱的聚合等等, 具体聚合的形式可能是不确定的, 甚至是 在标准中也不能一一确定的, 因为与实际的频谱资源、 网络规划、 各个运营商之间的频 谱划分等均有一定的关系。 因此需要更加灵活的资源分配方式。

实施本发明的方式
为了能够支持未来通信系统, 比如 LTE-A系统中, 可能存在的多种频谱聚合方式, 可以根据用户设备和网络的实际情况, 进行灵活的资源分配。本发明的实施例提供了一 种资源分配方法。
本发明实施例提供的资源分配方法中, 网络支持用户设备在多个频率频段内进行 聚合, UE—段时间内可能采用多种聚合模式, 这样可以适应 UE能力、 业务需求及网络 各载波负载等等的变化。 并且, 网络侧需要通知 UE可以采用的频谱聚合模式以及具体 每种频谱聚合模式定义的方法。
其中, 网络侧通知 UE频谱聚合模式,可以采用 UE特定的方式实现, 即 UE Specific, 比如采用 RRC (Radio Resource Control, 无线资源控制) 专有信令; 或者还可以采用用 户设备组特定的方式或者小区特定的方式实现, 比如采用广播。
其中, 频谱聚合模式可以包括: 不同层频率的载波聚合模式; 带宽的载波聚合模 式;或者小区频谱资源共享的载波聚合模式;或者小区间频谱 /载波干扰协调的聚合方式, 尤其应用在异构网络结构中, 避免宏小区和微小区之间的干扰。 可以根据 UE支持的聚 合能力, QoS, 或业务速率, 用户的业务需求, UE在小区的位置, 或网络的资源使用情 况等, 确定 UE在一段时间内可以采用的几种频谱聚合模式。
在本发明的一实施例中, 频谱聚合模式为不同层频率的载波模式时, 例如, 当一 个 UE支持低频或者高频两种传输模式, 可以根据 UE在小区的位置, 或者网络的资源使 用情况, 为 UE选择在一段时间内可以采用的频谱聚合模式包括: 一种载波聚合模式用 于在低频载波传输, 另一种载波聚合模式用于在高频载波传输, 这样网络可以在低频载 波内或是高频载波内灵活的进行资源分配。
在本发明的一实施例中, 频谱聚合模式为带宽的载波聚合模式, 例如, 当一个 UE 支持的带宽大小不同时, 尤其 UE可以采用多个射频链结构支持的多载波聚合时, 某一 个或是几个射频链是可以比较灵活的打开和关闭, 这样, 可以根据 UE的业务需求变化, 为 UE选择在一段时间内可以采用的频谱聚合模式, 比如一种载波聚合模式采用的带宽 比较大, 另外一种载波聚合模式采用的带宽比较小, 这样网络可以灵活的在较大带宽或 是较小带宽上进行资源分配。
在本发明的一实施例中, 频谱聚合模式为小区频谱资源共享的频谱聚合模式, 例 如, 在通信系统中, 当小区支持频谱共享技术时, 本小区暂时不用的频谱可以 "借"给 其它小区使用, 使得某些小区的可用频率资源增多。 比如同一地理位置的不同运营商的 不同频率的小区, 或者同一运营商的不同覆盖的两个小区。这时可以区分系统处于基本 载波场景, 也就是仅限于采用本小区分配的可用频谱, 或扩展载波场景, 也就是可以采 用本小区分配的可用频谱和从邻小区暂时 "借"用的频谱。 通知 UE可用的频谱聚合模 式,一种模式对应基本频率场景, 另外一种模式对应扩展载波场景, 这样网络可以灵活 的在基本或是扩展载波聚合场景上进行资源分配。
在本发明的一实施例中,频谱聚合模式可为小区间频谱 /载波干扰协调的聚合方式, 尤其应用在异构网络结构中, 避免宏小区和微小区之间的干扰。 例如, 异构网络中, 宏 小区和微小区采用干扰协调机制,分别采用不同的载波或是每个载波上不同的功率用于 给本小区内用户设备服务。 这时可以根据 UE在小区中的位置, 考虑覆盖的需求或是与 其他小区干扰的影响, 对于处在小区边缘或是与其他小区干扰较严重的位置时, 采用小 区间协调的载波传输模式,包括不同载波之间的协调或是相同载波不同功率等级之间的 协调; 对于处在小区中心或是与其他小区干扰较小的位置时, 可以采用小区间非协调载 波传输模式。 通知 UE可用的诸如上述的多种频谱聚合模式, 一种模式对应小区间载波 协调的模式, 另外一种模式对应小区间载波非协调模式, 这样网络可以灵活的在小区间 载波协调的模式或是非协调模式上进行资源分配。
本发明实施例中提供的资源分配方法, 把 UE在一段时间内可以采用的频谱聚合模 式以及具体每种频谱聚合模式定义的方法发送给 UE, 可以适应用户设备能力、 业务以 及各载波负载等的变化, 而且可以支持每一个 UE自由的频谱聚合, 使用户设备的资源 分配方式的灵活性不受频谱聚合的限制, 进而使得带宽在无限制扩展的情况下, 提供了 一种灵活的资源分配方法。具体的说,可以支持用户设备灵活的调度,或者更高的速率, 或较低的速率; 或者较少载波聚合, 或较多载波聚合; 或者较低频谱聚合, 或较高频谱 聚合或者采用小区干扰协调载波聚合, 或是采用小区干扰非协调载波聚合等等场景, 支 持灵活的多个载波聚合, 减少各种聚合场景带来的资源分配方法的限制。 而且, 即使有 新分配的频谱资源, 或新的频谱聚合方式时, 可以对现有网络层协议不会造成过多的修 改。 本发明实施例提供一种资源分配方法, 网络在用户设备的控制信道中承载该 UE将 采用的频谱聚合模式标识信息和资源分配信息,发送该频谱聚合模式标识信息和资源分 配信息发送给该 UE。 其中, 发送该频谱聚合模式标识信息和资源分配信息给 UE, 具体 可以通过包含该频谱聚合模式标识信息和资源分配信息的控制信令发给用户设备;或者 通过包含资源分配信息的扰码加扰的控制信令发给用户设备,其中频谱聚合模式标识信 息通过该扰码进行隐性的区分。 其中频谱聚合模式标识信息与频谱聚合模式是对应的。
其中, 网络发送频谱聚合模式标识信息和资源分配信息之前进一步包括, 通知 UE 可以采用的几种频谱聚合模式以及具体每一种频谱聚合模式定义的方法。
其中, UE采用的频谱聚合模式标识信息可以通过显性的方式进行通知, 如在控制 信令中有一个字域明确用于指示 UE的频谱聚合模式标识信息; 或是隐性的方式进行通 知, 如将 UE频谱聚合模式标识信息加扰控制信道用以区分。
具体的, 如果 UE采用的频谱聚合模式标识信息是通过显性的方式通知的, 那么频 谱聚合模式标识信息占用的比特数目与可以采用的频谱聚合模式个数是对应的。 比如, 假设 UE的频谱聚合模式的个数为 N, 而频谱聚合模式标识信息占用的比特数为 M, 那么
M =「 g2(N), , 其中符号「,表示向上取整。 另外, 如果 UE采用的频谱聚合模式标识信息是通过隐性的方式通知的, 那么频谱 聚合模式标识信息可以包含资源分配信息的控制信令所采用的不同扰码进行区分,或是 其他方式进行隐性承载。
其中, 根据 UE当前的业务需求或者网络的资源使用情况, 确定 UE的采用的频谱聚 合模式。
例如存在两种带宽, 如图 1所示系统带宽示例图。低频段 2.30G~2.34G,有两个 20M 载波, 共达到 40M带宽。 高频段 3.6G~3.7G, 有五个载波, 共达到 100M带宽。
比如, 对一个 UE, 网络侧确定 UE在一段时间内可以采用在低频多个载波传输和在 高频多个载波进行传输的两种载波聚合模式,带宽均达到 40M。通知 UE在这段时间内可 以采用这两种载波聚合模式及每种载波聚合模式的具体定义。 根据网络的资源使用情 况, 可以实现对用户设备灵活进行资源的分配。 如果确认 UE采用在低频多个载波进行 传输,在时间传输单元对应的控制信道中承载采用该低频载波传输的载波聚合模式标识 信息, 发送该采用低频载波传输的载波聚合模式标识信息给 UE, 指示在该低频多个载 波传输数据。 图 2中的斜线部分表示用户设备数据传输的频段。 如果确认 UE采用在高频 载波的两个连续载波传输, gP3.62G ~ 3.66G, 那么在时间传输单元对应的控制信道中承 载采用该高频载波传输的载波聚合模式标识信息,发送该采用高频载波传输的载波聚合 模式标识信息给 UE, 指示在该高频载波传输数据。 图 3中的网格部分表示用户设备数据 传输的频段。
比如, 对于一个 UE, 网络侧确定 UE在一段时间内可以采用不同的带宽的载波聚合 模式, 其中一种 20M, 满足一般业务的需求, 另一种为 60M, 可以满足用户设备高峰值 速率业务的需求, 网络可以根据 UE的业务需求以及变化, 动态的调整载波资源的分配, 尤其当两种带宽聚合模式是通过不同的射频链结构实现时,如果网络配置采用较小带宽 进行数据传输时, 其他射频链可以关闭, 有效降低用户设备的电池电量的消耗。 如果确 定 UE采用 20M带宽传输,假设为 3.60G ~ 3.62G,那么在时间传输单元对应的控制信道中 承载采用该 20M带宽上传输的载波聚合模式标识信息, 发送采用该 20M带宽上传输的载 波聚合模式标识信息给 UE, 指示在这 20M带宽上传输数据。 图 4中横线部分表示用户设 备数据传输的频段。如果确定 UE采用 60M带宽传输,假设为 3.60G ~ 3.66G, 那么在时间 传输单元对应的控制信道中承载采用该 60M带宽上传输的载波聚合模式标识信息, 发送 采用该 60M带宽上传输的载波聚合模式标识信息给 UE, 指示在这 60M带宽上传输数据。 图 5中竖线部分表示用户设备数据传输的频段。
本发明实施例中, 网络侧确定 UE在一段时间内可以采用小区频谱资源共享的频谱 聚合模式, 区分系统的载波应用场景, 确定 UE可以采用本小区分配的可用频谱, 还是 可以采用本小区分配的可用频谱和从邻小区暂时 "借"用的频谱, 通知 UE可以采用的 频谱, 指示该 UE在确定的频谱上传输数据。
其中, 本发明实施例中 UE采用的频谱聚合模式标识信息和资源分配信息可以承载 在一条控制信道上发给 UE, 也可以分别承载在多条控制信道上发给 UE。 比如, 当采用 多个频率段聚合给一个 UE使用时, 每个频率段的频域特性相对比较独立, 每个频率段 可以都对应至少一条控制信道, 包括该频率段的频谱聚合模式标识信息和资源分配信 息。 这样在多个频率段聚合给一个 UE使用的情况下, 网络采用多条控制信道通知该 UE 的数据调度情况, 使得支持载波聚合的情况下也不过多增加现有系统中控制信道的格 式。
其中, 如果 UE对应的控制信道可以在某些载波上传输。 如果在每个时间单元内, 即一个子帧内, 网络将用户设备的控制信道采用某些载波中的一个载波进行传输时, 该 载波的确定方法可以采用专有信令通知 UE或是网络和用户设备已知的随机化方法来确 定。 这样, 可以避免在每个时间单元内, 用户设备对所有可能传输控制信道的载波都进 行盲检测, 减少了用户设备对控制信道的盲检测次数, 也降低了用户设备的处理复杂度 和电池消耗。
其中, 本发明实施例中, 仍可以采用资源分配类型 type 0、 type 1和 type 2来指示被 调度给 UE的频谱资源的分配信息。 仍然可以采用盲检测的方法来区分是 type 2还是 type 0, 或 type 1, 其中 type 0和 type 1通过控制信令中具体承载的类型信息来区分。 如果频谱 聚合使得系统带宽大于 20M, 对于 type 0和 type 1 采用现有方案的方法, 但 P的数值进 一步增大,最终使得在不同的系统带宽情况下,资源分配信息所占用的比特数比较接近, 不会因为系统带宽的增加而线性增加。
动态的在每个时间传输单元对应的控制信道中承载 UE具体采用的资源分配信息。 每个时间传输单元对应的控制信道中 UE具体采用的资源分配信息所占用的比特数尽量 保持相等, 这样, 可以减少用户设备的盲检测次数。 在本发明的一实施例中, 可以在资 源分配信息后面增加一定数目的填充比特,使得最终的信息长度与控制信道中最长信息 长度保持一致; 或者在本发明的一实施例中, 可以采用其他中间长度的方法, 总之, 对 于相同的资源分配类型, 或是具有相同信息长度的资源分配类型情况下, 比如具有相同 信息长度的 type 0和 type 1, 资源分配信息在控制信道中所占的比特数目相同, 进而使承 载频谱聚合模式标识信息和该资源分配信息的控制信令的信息长度保持相等。
方法一, 资源分配类型相同情况下, 与资源分配信息所需要的比特数最多的长度 对齐, 使得资源分配信息的长度相同。
假设用户设备用户支持 2种模式, 均采用 type 0 资源分配方式。 模式一: 资源分配 的带宽是 20M, 模式二: 两个 20M频谱聚合的资源分配。 对于 20M系统带宽, 资源分配需要 6 =「^^ //5] = ^10°/ 4^ = 25bits ,资源分配 信息所占用的比特数如图 6中左斜单元格所示:。
对于两个 20M频谱聚合, 其系统带宽可以认为是 40M, 如果采用的表一中 P, 可以 把 40M对应的 P扩展为 7, 资源分配需要^£=「^^;/ 73, =「200/ 7, = 2%to , 资源分配 信息所占用的比特数如图 7中右斜单元格所示。
从图 6和图 7可知, 模式一的资源分配信息所占用的比特数目较模式二少 4个比特, 为了使最后的长度一样, 需要在模式一的信息尾部, 但位于 CRC之前补充 4个比特, 补 充的结果如图 8中的十字花格子所示。 方法二, 资源分配类型相同情况下, 各种模式的资源分配信息所占用的比特数需 要折中某一长度, 可以采用修改表一中的 P值, 或者说表一中的 P值仅表示默认值, 可以 通知用户设备用户进行修改, 并非是完全固定的, 进而使得各种模式的资源分配信令信 息长度相同。
如上所述的例子, 对于两个 20M频谱聚合的模式二, 其系统带宽可以认为是 40M, 如果对应的表一中 P, 上面例子默认为 7, 可以通过信令把 P修改成 8, 那么资源分配信 息所占用的比特数目为^^ =「^^ ] =2(Κ) / 8, = 25bits , 资源分配信息所占用的比 特数目为图 9中右斜单元格所示,其资源分配信息所占用的比特数目恰好和模式一相同。
本发明实施例中, 结合半静态信令通知可能采用的几种载波聚合模式及动态的控 制信道指示具体载波聚合模式标识和具体资源分配信息,可以减少对控制信道的盲检测 次数。
本发明实施例提供一种获取资源的方法, 如图 11所示, 该方法包括:
1101、 接收频谱聚合模式标识信息和资源分配信息;
1102、 根据该频谱聚合模式标识信息获得该用户设备可用的时频资源;
1103、 根据该资源分配信息获得该时频资源的位置。
在本发明实施例中, 频谱聚合模式标识信息和资源分配信息是承载在每个时间单 元对应的控制信道中发给 UE。 该控制信道传输所占用的频域位置可以是某一个或者某 些载波上传输的。 例如只在低频的几个载波上传输所述的控制信道, 如图 10所示。 UE 得到控制信道的内容, 根据其中的信息得到频谱聚合模式标识信息, 再通过资源分配信 息, 进而得到数据信道的分配信息, 即数据信道传输的位置信息。
其中, 如果 UE对应的控制信道可以在某些载波上传输, 那么在每个时间单元内, 网络将该控制信道采用某些载波中的一个载波进行传输,该载波的确定方法可以采用专 有信令通知 UE或是网络和用户设备已知的随机化方法来确定。 这样, 可以避免在每个 时间单元内,用户设备对所有可能传输控制信道的载波都进行盲检测,减少盲检测次数。
其中, 根据该资源分配信息获得该时频资源的位置具体包括: 通过盲检测的方式 和 /或承载在控制信令中的资源类型指示信息获得资源分配类型,进而确定时频资源的位 置信息。
其中, 接收频谱聚合模式标识信息和资源分配信息之前进一步包括, 接收 UE可以 采用的频谱聚合模式以及每种频谱聚合模式定义的方法,根据频谱聚合模式信息和频谱 聚合模式定义方法获得用户设备可用的时频资源。 进一步包括, 用户设备在该时频资源上接收数据或发送数据。
