Description

多载波聚合的方法、 装置、 用户设备及网络侧设备
技术领域
[01] 本发明涉及通信领域,尤其涉及一种多载波聚合的方法、装置、用户设备(STA) 及网络侧设备。 背景技术
[02] 越来越多的应用场景, 日益增加的数据传输需求, 使得无线网络的负载越来越 重。无线网络从诸多技术层面予以改进和升级,在这些技术中最简单直接的方式就是 增加频谱资源。对于受到频谱管理机构严格管控的频谱,通过购买执照的方式获得的 频谱很难连续分布, 需要通过利用频谱资源碎片的技术来提高数据传输峰值速率。对 于免费频谱, 无线设备只要符合功率限制就可以使用, 但是, 无线通信的数据传输通 常需要一定的信噪比, 而免费频谱随时都有可能被某些设备使用, 因而使用免费频谱 进行通信同样需要通过利用频谱资源碎片的技术来提高数据传输峰值速率。
[03] 当前的日常生活中, 数据传输的迅猛增长与无线通信带宽的矛盾日益加深, 同 时无线频谱资源碎片化、零散化趋势更增加了大数据量传输的难度, 为了充分利用频 谱资源, 满足日益增加的数据传输的需求, 载波聚合技术应运而生, 而且该技术恰恰 能利用频谱资源碎片来解决上述的问题。
[04] 载波聚合技术从概念上来讲就是聚合两个或更多的成员载波, 从而满足更大的 带宽和更高的数据传输速率的需求。载波聚合按照频谱资源碎片的程度可以分为连续 载波聚合与其非连续载波聚合, 如图 1所示。
[05] 另一方面, 承载数据传输的网络资源是有限的, 由于 802.11标准是基于载波监 听多路访问 /冲突检测 (CSMA/CA, Carrier Sense Multiple Access/Collision Detect) 的 机制, 只要存在竞争网络资源的情况, 就会出现服务质量 (QoS, Quality of Service) 的问题。 首先, 由于数据传输量增长和数据业务分类细化, 从而对传输资源分配、 传 送时延、 数据丢包率以及时延抖动提出了更高的要求, 如图 2所示。 其次, 由于总传 输资源有限,某类业务占用越多传输资源来传输数据,那么其他的业务能用来传输数 据的传输资源就越少, 因而对 802.11 网络中各种业务的传输资源的规划和分配同样 提出了更高的要求。
[06] 在 802.11标准的现有机制中, 通过把信道带宽划分为主载波和辅载波, 增加信 号传输带宽来提高数据传输的峰值速率, 如图 3所示, 主 40MHz载波包括主 20MHz 载波和辅 20MHz载波; 主 80MHz载波包括主 40MHz载波和辅 40MHz载波; 主 160MHz载波(图中未示出)包括主 80MHz载波和辅 80MHz载波, 以此类推。 802.11 标准中的机制类似于载波聚合,然而这种机制需要对载波竞争接入。载波竞争接入的 顺序为主载波、辅 20MHz载波、辅 40MHz载波、辅 80MHz载波。依照这样的顺序, 只有当上述顺序中前一个载波允许接入使用时, 接入点 (AP, Access Point) 或者用 户设备才会竞争后一个载波,最后把允许接入的载波组合在一起构成一个大带宽信道 来传输数据。
[07] 载波分优先级竞争接入的机制会造成 AP 或者用户设备如果对优先级高的载波 竞争失败就会放弃竞争优先级低的载波的情况, 因而妨碍了低优先级载波的使用, 使 得各载波的负载不均衡, 降低了低优先级载波的利用率。 发明内容
[08] 本发明实施例中提供了一种多载波聚合的方法、装置、用户设备及网络侧设备, 能够提高载波尤其是低优先级载波的利用率。
[09] 第一方面, 提供一种多载波聚合的方法, 包括:

[43] 下面将结合本发明实施例中的附图, 对本发明实施例中的技术方案进行清楚、 完整的描述, 显然, 所描述的实施例仅仅是本发明一部分实施例, 而不是全部的实施 例。基于本发明中的实施例,本领域普通技术人员在没有付出创造性劳动前提下所获 得的所有其他实施例, 都属于本发明保护的范围。
[44] 本发明实施例中将通信系统的频带资源划分为若干个成员载波(CC, Component Carrier) , 所有的成员载波的带宽都是可以变化的。
[45] 以下对本发明实施例成员载波在时间上的划分进行说明,如图 4A所示,各个成 员载波在时间上通过上下行切换点划分为成员载波的上行时间和成员载波的下行时 间, 不同成员载波的上下行切换点在时间上一致, 也即各个成员载波的上下行切换点 在时间上对齐。例如图 4A中 (在图 4A中将上下行切换点简称为切换点), 成员载波 1包括切换点 11~切换点 15, 成员载波 2包括切换点 21~切换点 25, 成员载波 3包括 切换点 31~切换点 35, 成员载波 4包括切换点 41~切换点 45, 其中, 切换点 11、 切 换点 21、 切换点 31、 切换点 41均位于 tl时刻, 因此这些切换点在时间上一致, 也 可以称为在时间上对齐; 同样的, 切换点 12、 切换点 22、 切换点 32、 切换点 42均 位于 t2时刻, 这些切换点也在时间上一致, 其他切换点依次类推, 不再赘述。 另外, 切换点 11与切换点 12之间、切换点 21与切换点 22之间、切换点 31与切换点 32之 间、 切换点 41与切换点 42之间分别是成员载波 1~4的上行时间, 切换点 12与切换 点 13之间、 切换点 22与切换点 23之间、 切换点 32与切换点 33之间、 切换点 42 与切换点 43之间分别是成员载波 1~4的下行时间。
[46] 一般的, 成员载波的上行时间和下行时间的时间长度相同, 也即相邻两个上下 行切换点之间的时间长度相同。所述时间长度的具体数值可以自主设置, 且可以在实 际应用中进行数值更新和改变, 这里并不限定。但是, 成员载波的上行时间和下行时 间的时间长度也可以不同, 本发明实施例并不限制。
[47] 其中, 在成员载波的上行时间内, 网络侧设备能够调度用户设备使用各个空闲 的成员载波将上行业务数据发送至网络侧设备; 在成员载波的下行时间内, 网络侧设 备能够调度网络侧设备使用各个空闲的成员载波将下行业务数据发送至各个用户设 备。
[48] 另外, 本发明实施例中各个成员载波上的数据传输也是基于竞争的, 例如通过 现有技术中的 CSMA/CA机制进行所述竞争, 即通过竞争获得发送数据的机会。调度 时间段 (SP, Scheduling Phase) 可以为在成员载波上通过竞争获得进行上行或下行 传输的时间段, 竞争时间段 (CP, Contention Phase) 可以为在成员载波上除调度时 间段之外的时间段, 当然调度时间段和竞争时间段也可以被称为其他名称, 也属于本 发明保护的范围。 例如图 4A中 SP1 SP4分别是调度时间段, CP1 CP9分别是竞争 时间段。
[49] 所述调度时间段可以由网络侧设备在成员载波的下行时间通过竞争获得, 也可 以由网络侧设备在成员载波的上行时间通过竞争获得,可以在调度时间段竞争成功之 后释放所述调度时间段的全部时间段或者部分时间段;所述调度时间段也被所述上下 行切换点划分为调度时间段的上行时间段和调度时间段的下行时间段,调度时间段的 上行时间段内的传输资源对应上行传输资源,调度时间段的下行时间段内的传输资源 对应下行传输资源,调度时间段的上下行时间段是成员载波的上下行时间的部分或全 部。调度时间段的下行时间段内的下行传输资源用于网络侧设备与用户设备进行下行 传输,调度时间段的上行时间段内的上行传输资源用于用户设备与网络侧设备进行上 行传输。 例如, 图 4A中所示, 调度时间段 SP1对应着成员载波 1、 2, 被切换点 12 和切换点 22划分为上行时间段和下行时间段; 调度时间段 SP2对应着成员载波 1, 被切换点 14划分为上行时间段和下行时间段。
[50] 其中, 本发明实施例中所述的传输资源例如上行时间段内的上行传输资源、 下 行时间段内的下行传输资源等可以为空间域、 时间域、 频率域和 /或码域的传输资源, 本发明实施例并不限定。
[51] 其中, 本发明实施例所称之网络侧设备可以为: AP、 基站等, 这里并不限定。
[52] 参见图 4, 为本发明多载波聚合的方法第一实施例示意图, 该方法包括:
[53] 步骤 401 :网络侧设备根据对至少一个成员载波竞争成功得到的传输资源的信息 确定所述至少一个成员载波对应的调度时间段的起止时间,其中,所述调度时间段被 上下行切换点划分为调度时间段的上行时间段和调度时间段的下行时间段;所述上下 行切换点用于在时间上划分成员载波的上行时间和成员载波的下行时间; 并且, 当所 述至少一个成员载波为两个或两个以上成员载波时,所述两个或两个以上成员载波的 上下行切换点在时间上对齐;
[54] 步骤 402: 网络侧设备在调度时间段的下行时间段与用户设备进行下行传输; 网 络侧设备在调度时间段的上行时间段与用户设备进行上行传输。
[55] 本实施例中, 成员载波之间没有竞争接入的优先级关系, 从而使得各个成员载 波被接入的机会均等,成员载波负载均衡, 从而能够提高现有技术中载波尤其是低优 先级载波的利用率。
[56] 参见图 5, 为本发明多载波聚合的方法第二实施例示意图, 该方法包括:
[57] 步骤 501 : 用户设备在调度时间段的下行时间段与所述网络侧设备进行下行传 输;
[58] 步骤 502:用户设备在所述调度时间段的上行时间段与所述网络侧设备进行上行 传输;
[59] 其中, 所述调度时间段的起止时间由网络侧设备根据对至少一个成员载波竞争 成功得到的传输资源的信息确定,所述调度时间段被上下行切换点划分为调度时间段 的上行时间段和调度时间段的下行时间段;所述上下行切换点用于在时间上划分成员 载波的上行时间和成员载波的下行时间;
[60] 当所述至少一个成员载波包括两个或两个以上的成员载波时, 所述两个或两个 以上成员载波的上下行切换点在时间上对齐。
[61] 其中, 步骤 501和步骤 502之间没有执行顺序的限制, 其与调度时间段的上行 时间段和下行时间段的时间顺序相关, 例如图 4A所示, 成员载波 3对应的调度时间 段 SP3被切换点 31、 32、 33、 34、 35划分为多个上行时间段和下行时间段, 用户设 备将在切换点 31和 32之间的调度时间段 SP3的下行时间段执行步骤 501,之后在切 换点 32和 33之间的调度时间段 SP3的上行时间段执行步骤 502, 之后在切换点 33 和 34之间的调度时间段 SP3的下行时间段执行步骤 501, 最后在切换点 34和 35之 间的调度时间段 SP3的上行时间段执行步骤 502, 依此类推。
[62] 本实施例中, 用户设备在调度时间段的下行时间段与所述网络侧设备进行下行 传输,在所述调度时间段的上行时间段与所述网络侧设备进行上行传输, 从而与网络 侧设备配合, 实现了与网络侧设备的上下行传输, 提高了成员载波的利用率。

[64] 步骤 601 : 网络侧设备确定上下行切换点, 在各个成员载波的上行时间和 /或下 行时间内周期性广播所述上下行切换点。
[65] 网络侧设备将所述上下行切换点广播给各个用户设备, 从而使得网络侧设备和 用户设备之间对于成员载波的上下行时间的划分同步。
[66] 其中, 广播所述上下行切换点的具体周期长度可以在实际应用中自主设置, 本 发明并不限制。
[67] 一般的, 网络侧设备可以在一段时间之内只执行一次所述步骤 601,确定一段时 间内的所有上下行切换点, 并周期性广播给各个用户设备。
[68] 其中, 网络侧设备具体如何将上下行切换点广播给各个用户设备本发明并不限 制, 例如可以通过自定义的帧来广播所述上下行切换点等。
[69] 步骤 602: 网络侧设备对至少一个成员载波分别进行竞争,获得对成员载波竞争 成功得到的传输资源;
[70] 其中, 网络侧设备要竞争的所述至少一个成员载波可以是网络侧设备侦听到的 能够被聚合的成员载波。网络侧设备对侦听到的能够被聚合的成员载波分别进行竞争 时, 可以基于现有的 CSMA/CA竞争机制实现, 这里不限定。 网络侧设备可以通过侦 听网络分配矢量(NAV)或检测接收信号能量来确定是否对成员载波竞争成功; 所述 NAV由网络侧设备或者用户设备在对成员载波竞争成功时发送。
[71] 步骤 603 : 网络侧设备根据各个业务的 QoS确定成员载波的传输方式。
[72] 其中, 所述传输方式可以包括: 调度传输方式以及竞争传输方式, 其中, 所述 竞争传输方式的具体传输方法可以基于现有的 CSMA/CA竞争机制实现,以便与现有 技术兼容, 例如, 网络侧设备确定使用竞争传输方式时, 网络侧设备确定竞争传输的 传输机会 (TXOP) 的起止时间, 所述 TXOP的起止时间位于所述成员载波的下行时 间内; 网络侧设备使用所述 TXOP与用户设备进行下行传输。以下不再对所述竞争传 输方式进行过多赘述,通过下述步骤 605 607描述网络侧设备确定成员载波的传输方 式为调度传输方式时网络侧设备所执行的处理过程。
[73] 其中, 各个业务可以包括下行业务和上行业务; 下行业务的 QoS可以直接由网 络侧设备确定, 而上行业务的 QoS可以由上行业务对应的用户设备上报至网络侧设 备; 网络侧设备具体如何确定各个业务的 QoS这里不赘述。
[74] 其中, 步骤 603为可选步骤。
[75] 步骤 604: 网络侧设备接收用户设备发送的传输资源信息,所述传输资源信息包 括: 用户设备对至少一个成员载波竞争成功得到的传输资源的信息。
[76] 其中, 用户设备如何对成员载波进行竞争可参考步骤 602中网络侧设备对成员 载波进行竞争的说明, 这里不赘述。
[77] 并且,用户设备也可以通过侦听 NAV或检测接收信号能量来确定是否对成员载 波竞争成功; 所述 NAV由网络侧设备或者用户设备在对成员载波竞争成功时发送。
[78] 步骤 605 :网络侧设备根据对至少一个成员载波竞争成功得到的传输资源的信息 确定所述至少一个成员载波对应的调度时间段的起止时间;
[79] 其中, 所述对至少一个成员载波竞争成功得到的传输资源的信息中的所述传输 资源可以包括: 步骤 602中网络侧设备对成员载波竞争成功得到的传输资源, 和 /或, 步骤 604中用户设备发送的、用户设备对成员载波竞争成功得到的传输资源,本发明 并不限制。
[80] 其中, 当所述对至少一个成员载波竞争成功得到的传输资源的信息中的所述传 输资源仅包括: 步骤 602中网络侧设备对成员载波竞争成功得到的传输资源时, 步骤 604可以不执行; 当所述对至少一个成员载波竞争成功得到的传输资源的信息中的所 述传输资源仅包括: 步骤 604中用户设备发送的、用户设备对成员载波竞争成功得到 的传输资源时, 步骤 602可以不执行。
[81] 其中, 网络侧设备根据对至少一个成员载波竞争成功得到的传输资源的信息确 定所述至少一个成员载波对应的调度时间段的起止时间可以包括:
[82] 网络侧设备根据对至少一个成员载波竞争成功得到的传输资源的信息确定所述 调度时间段的起始时间;
[83] 网络侧设备确定所述调度时间段的持续时间;
[84] 网络侧设备根据所述调度时间段的起始时间和持续时间确定调度时间段的起止 时间。
[85] 在一种可能的实现方式中, 网络侧设备根据对至少一个成员载波竞争成功得到 的传输资源的信息确定所述调度时间段的起始时间可以包括:
[86] 网络侧设备根据对首个成员载波竞争成功的时间以及预设第一时间确定所述调 度时间段的起始时间; 例如, 网络侧设备将网络侧设备对首个成员载波竞争成功的时 间经过预设第一时间得到的时间作为所述调度时间段的起始时间。
[87] 例如, 网络侧设备对成员载波 1、 2、 3、 4分别进行竞争, 最先对成员载波 2竞 争成功, 那么所述首个成员载波就是所述成员载波 2, 所述对首个成员载波竞争成功 的时间就是对成员载波 2竞争成功的时间。
[88] 其中, 所述第一时间的具体取值可以在实际应用中自主设定, 本发明并不限制。
[89] 在另一种可能的实现方式中, 网络侧设备根据对至少一个成员载波竞争成功得 到的传输资源的信息确定所述调度时间段的起始时间可以包括:
[90] 网络侧设备根据接收到首个用户设备上报传输资源的信息的时间以及预设第二 时间确定所述调度时间段的起始时间; 例如, 网络侧设备将网络侧设备接收到首个用 户设备上报的传输资源信息的时间经过预设第二时间得到的时间确定为所述调度时 间段的起始时间。
[91] 例如, 网络侧设备接收到了用户设备 、 B、 C分别上报的传输资源信息, 其中 第一个接收到的是用户设备 c 上报的传输资源信息, 那么所述首个用户设备是用户 设备 C,网络侧设备接收到首个用户设备上报传输资源信息的时间为网络侧设备接收 到用户设备 C上报的传输资源信息的时间。
[92] 其中, 所述第二时间的具体取值可以在实际应用中自主设定, 本发明并不限制。
[93] 其中, 网络侧设备确定所述调度时间段的持续时间可以包括:
[94] 网络侧设备将预设的第三时间作为所述调度时间段的持续时间; 或者,
[95] 网络侧设备根据业务的业务量和 /或 QoS确定所述调度时间段的持续时间。其中 所述业务可以是网络侧设备在所述调度时间段内需要传输的业务。
[96] 其中, 所述第三时间的具体取值可以在实际应用中自主设定, 本发明并不限制。
[97] 以下对网络侧设备根据业务的业务量和 /或服务质量 QoS 确定所述调度时间段 的持续时间的实现举例说明:
[98] 其中, 调度时间段的持续时间的计算公式可以为: 持续时间=常数因子 X业务量 ÷QoS;其中,所述业务量和 QoS具体通过哪些参数来表示可以在实际应用中自主设 定, 这里并不限制; 所述常数因子的具体取值可以在实际应用中自主设定, 这里并不 限制。例如,所述调度时间段的持续时间可以由频谱管理机构规定的非授权频段最大 持续时间 T除以数据包时延和数据错误率的乘积来获得,该非授权频段最大持续时间 T是一个与业务的业务量相关的时间长度,而数据包时延和数据错误率则用于表示业 务的 QoS。
[99] 以上持续时间确定方法仅为示例, 在实际应用中也可以通过其他方法来确定调 度时间段的持续时间, 这里并不限定。
[100]其中, 所述至少一个成员载波对应的所述调度时间段被所述上下行切换点划分 为下行时间段和上行时间段; 相应的,所述至少一个成员载波对应的调度时间段内的 传输资源也被上下行切换点划分为调度时间段的上行时间段内的上行传输资源、调度 时间段的下行时间段内的下行传输资源;所述至少一个成员载波对应的调度时间段的 上行时间段内的上行传输资源包括:所述至少一个成员载波中每个成员载波在所述上 行时间段内的传输资源,所述至少一个成员载波对应的调度时间段的下行时间段内的 下行传输资源包括:所述至少一个成员载波中每个成员载波在所述下行时间段内的传 输资源。 例如, 图 4A中成员载波 1、 2对应的调度时间段 SP1被切换点 12和切换点 22划分为上行时间段和下行时间段, 调度时间段 SP1 的上行时间段内的上行传输资 源包括:成员载波 1在调度时间段 SP1的上行时间段内的传输资源、成员载波 2在调 度时间段 SP1 的上行时间段内的传输资源; 调度时间段 SP1 的下行时间段内的下行 传输资源包括:成员载波 1在调度时间段 SP1的下行时间段内的传输资源、成员载波 2在调度时间段 SP1的下行时间段内的传输资源。

[102]其中, 如果本发明实施例中的传输资源为时间域的传输资源, 则所述上行资源 块或者下行资源块可以以时间片的形式实现,具体时间片的划分可以但不限于通过时 分多址 (TDMA, Time Division Multiple Access) 技术实现。
[103]其中, 如果本发明实施例中的传输资源为时间域和频率域的传输资源, 则所述 上行资源块或者下行资源块可以以时频资源块的形式实现,时频资源块的划分可以但 不限于通过正交频分多址 ( OFDMA, Orthogonal Frequency Division Multiple Access) 技术实现。
[104]另外, 如果本发明实施例中的传输资源为频率域的传输资源, 则所述上行资源 块或者下行资源块可以以频率资源块的形式实现;如果本发明实施例中的传输资源为 空间域的传输资源, 则所述上行资源块或者下行资源块可以以空间资源块的形式实 现; 如果本发明实施例中的传输资源为码域的传输资源, 则所述上行资源块或者下行 资源块可以以码资源块的形式实现;如果本发明实施例中的传输资源为时间域和空间 域的传输资源, 则所述上行资源块或者下行资源块可以以空时资源块的形式实现; 如 果本发明实施例中的传输资源为频率域和空间域的传输资源,则所述上行资源块或者 下行资源块可以以空频资源块的形式实现; 如果本发明实施例中的传输资源为频率 域、空间域和时间域的传输资源, 则所述上行资源块或者下行资源块可以以空时频资 源块的形式实现。
[105]步骤 606:网络侧设备将关于所述竞争成功得到的传输资源以及传输方式的信息 发送至各个用户设备。
[106]具体的, 网络侧设备可以通过媒体访问控制 (MAC, Media Access Control) 层 消息将关于所述竞争成功得到的传输资源以及传输方式的信息发送至各个用户设备。
[107]其中, 步骤 606为可选步骤, 步骤 605和步骤 606之间的执行顺序不限制。
[108]步骤 607: 网络侧设备在调度时间段的下行时间段与用户设备进行下行传输; 网 络侧设备在调度时间段的上行时间段与用户设备进行上行传输。
[109]其中, 如果所述至少一个成员载波对应的调度时间段的上行时间段内的上行传 输资源包括至少一个上行资源块,则网络侧设备在调度时间段的上行时间段与用户设 备进行上行传输可以包括:
[110]网络侧设备从所述调度时间段的上行时间段内的上行传输资源中为所述用户设 备分配至少一个成员载波上的至少一个上行资源块;
[ill]网络侧设备向所述用户设备发送为所述用户设备分配的至少一个成员载波上的 至少一个上行资源块的信息,以便于所述用户设备在对应的成员载波上使用为所述用 户设备分配的上行资源块与网络侧设备进行上行传输。
[112]其中, 网络侧设备从所述调度时间段的上行时间段内的上行传输资源中为所述 用户设备分配至少一个成员载波上的至少一个上行资源块可以包括:
[113]网络侧设备确定为用户设备分配传输资源的顺序;
[114]网络侧设备按照确定的顺序依次从所述调度时间段的上行时间段内的上行传输 资源中为每个用户设备分配至少一个成员载波上的至少一个上行资源块。
[115]其中, 网络侧设备为每个用户设备分配上行资源块时可以根据用户设备需要向 网络侧设备传输的上行业务的业务量分配,也可以按照预先设置的某一个上行资源块 的数值确定, 本发明并不限制。
[116]其中, 如果所述至少一个成员载波对应的调度时间段的下行时间段内的下行传 输资源包括至少一个下行资源块,则网络侧设备在调度时间段的下行时间段与用户设 备进行下行传输可以包括:

[122]网络侧设备按照确定的顺序依次从所述调度时间段的下行时间段内的下行传输 资源中为每个用户设备分配至少一个成员载波上的至少一个下行资源块。
[123]其中, 网络侧设备为每个用户设备分配下行资源块时可以根据网络侧设备向用 户设备传输的下行业务的业务量分配,也可以按照预先设置的某一个下行资源块的数 值确定, 本发明并不限制。
[124]其中, 网络侧设备确定为用户设备分配资源的顺序时, 可以根据用户设备是否 上报了传输资源信息、 和 /或用户设备的优先级、 和 /或用户设备所要传输的业务量、 和 /或用户设备的编号顺序来确定。 具体的, 上报了传输资源信息的用户设备比未上 报传输资源信息的用户设备顺序靠前,优先级相对较高的用户设备比优先级相对较低 的用户设备的顺序靠前,业务量相对较大的用户设备比业务量相对较小的用户设备的 顺序靠前,编号相对较小的用户设备比编号相对较大的用户设备顺序靠前。在实际应 用中, 网络侧设备具体如何根据上述排序条件确定为用户设备分配资源的顺序,本发 明并不限制。例如, 在轮询调度算法中, 按照用户设备的编号来确定为用户设备分配 传输资源的顺序,进一步的,还可以根据用户设备是否上报了传输资源信息来调整用 户设备的编号顺序, 从而确定为用户设备分配传输资源的顺序; 在比例公平调度算法 中, 按照用户设备的优先级确定为用户设备分配传输资源的顺序, 进而, 还可以根据 用户设备是否上报了传输资源信息来调整用户设备的优先级(例如将上报了传输资源 信息的用户设备的优先级乘以一个大于 1的常数因子,使得上报了传输资源信息的用 户设备的优先级提高等), 从而确定为用户设备分配传输资源的顺序; 等等。
[125]本实施例中, 由于网络侧设备在竞争接入成员载波时, 不再按照成员载波的优 先级竞争接入, 从而使得各个成员载波被接入的机会均等, 成员载波负载均衡, 从而 提高了现有技术中低优先级载波的利用率; 而且, 网络侧设备为用户设备分配不同的 成员载波和不同的上行资源块进行上行传输,为用户设备分配不同的成员载波和不同 的下行资源块进行下行传输, 不再按照一个带宽整体配置, 使得成员载波以及成员载 波上的传输资源分配更为灵活, 从而从另一个方面提高了成员载波的利用率, 降低了 带宽的浪费。
