为使本发明实施例的目的、技术方案和优点更加清楚, 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、完整地描述,显然, 所描述的实施例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, 都属于本发明保护的范围。
图 1为本发明宏基站和小基站的应用场景图,如图 1所示,有 3个小基站 和 1个宏基站及用户设备, A区域为宏基站的覆盖范围, B区域、 C区域、 D 区域分别为小基站 1、 小基站 2、 小基站 3的覆盖范围, 在该场景下, 小基站 和宏基站同时承担用户设备的同一数据业务传输,用户设备需要分别向小基站 和宏基站发送上行数据, 下面详细介绍小基站和宏基站如何准确获知 UE上报 的緩存状态报告。
图 2为本发明緩存状态报告发送方法实施例一的流程图,如图 2所示,本实 施例的方法可以包括:
步骤 101、接收宏基站发送的用于请求用户设备 UE发送緩存状态报告的指 示信息。
步骤 102、 根据指示信息, 向宏基站和 /或至少一个小基站发送緩存状态报 告 BSR, 所述宏基站和至少一个小基站共同服务于所述 UE, 所述宏基站的服 务范围大于所述至少一个小基站中每个小基站的服务范围。
在步骤 101中, 指示信息包括指示在每个业务中向宏基站和至少一个小基 站分别传输的数据量的信息,指示信息还包括宏基站发送的用于指示 BSR的接 收基站的信息, 接收到指示信息后, UE根据指示信息指示的 BSR的接收基站 向这些基站发送 BSR; 另外, UE接收宏基站发送的指示信息之后还可接收宏 基站或小基站发送的用于变更 BSR的接收基站的更新信息, 接收到更新信息 后, UE根据更新信息指示的变更 BSR的接收基站向这些基站发送 BSR,指示信 息或更新信息可以是无线资源控制信令 RRC信令、广播消息、媒体访问控制层 MAC控制信令、 物理层的控制信令中的一种, 其中指示信息和更新信息可以 是一个 RRC信令或一条广播消息或一个 MAC控制信令或一个物理层的控制信 令。
在本实施例步骤 101中, UE接收宏基站发送的指示信息, 指示信息包括指 示在每个业务中向宏基站和至少一个小基站分别传输的数据量的信息,本实施 例中有两种实施方案, 作为一种可实施的方式:
UE接收宏基站发送的每个业务的分流比例信息, 分流比例信息用于指示 向宏基站和至少一个小基站分别传输的数据量, UE接收到分流比例信息后, 根据每个业务的分流比例信息,确定与宏基站对应的每个逻辑信道组的第一緩 存数据量和 /或与至少一个小基站对应的每个逻辑信道组的緩存数据量, 具体 地, 采用 Bi * Mi计算获取第一緩存数据量, 采用 Bi*Si计算获取至少一个 小基站对应的每个逻辑信道组的緩存数据量, 其中, Mi为分流比例信息中与 宏基站对应的数据传输比例, Si为分流比例信息中小基站对应的数据传输比 例, N为一个逻辑信道组 LCG中的业务个数, Bi为每个业务对应的当前緩存数
据量。 如果有多个小基站, 那么每个小基站的 Si可能不同, 在计算的时候按照 每个小基站的 Si计算緩存数据量。 然后 UE向宏基站发送与第一緩存数据量对应的 BSR和 /或向至少一个小基 站发送与小基站对应的每个逻辑信道组的緩存数据量对应的 BSR, 或者, 向宏 基站发送与第一緩存数据量对应的 BSR和 /或与至少一个小基站的每个逻辑信 道组的緩存数据量对应的 BSR, 或者, 向至少一个小基站发送与第一緩存数据 量对应的 BSR和 /或与至少一个小基站的每个逻辑信道组的緩存数据量对应的 BSR, 此时, 比如 UE向宏基站发送与第一緩存数据量对应的 BSR和 /或与至少 一个小基站的每个逻辑信道组的緩存数据量对应的 BSR,宏基站接收到之后可 以将与至少一个小基站的每个逻辑信道组的緩存数据量对应的 BSR转发给对 应的小基站, 如果 UE向至少一个小基站发送与第一緩存数据量对应的 BSR和 / 或与至少一个小基站的每个逻辑信道组的緩存数据量对应的 BSR,小基站接收 到之后可以将与第一緩存数据量对应的 BSR转发给宏基站,将与其他小基站对 应的每个逻辑信道组的緩存数据量对应的 BSR转发给对应的每个小基站。 BSR 中还包括 LCID或基站序号, LCID用于标识需要转发的 BSR, 基站序号用于标 识 BSR需要被转发的目的基站, 当一个 BSR需要由宏基站转发给小基站, 或由 小基站转发给宏基站, UE需要使用新的 LCID标识 BSR, 用于区分原来 BSR对 应的 LCID,当宏基站或小基站接收到带有新的 LCID标识的 BSR,需要将该 BSR 转发给对应的宏基站或小基站。 另外还有一种方法, 在现有的 BSR结构中增加 新的标识, 例如基站序号(index ) , 用于标识 BSR需要转发的目的基站。 一次 发送的 BSR信息中可以携带多个需要转发的 BSR信息, 分别用转发的目的基站 序号标识。 当宏基站或一个小基站接收到带有基站序号的 BSR, 该宏基站或一 个小基站需要将该 BSR转发给对应的宏基站或其他小基站,基站序号是由宏基 站配置的。
需要说明的是, UE触发宏基站和至少一个小基站的 BSR的时间可能不同,
UE向宏基站和至少一个小基站发送 BSR的时间也可能不同。 如果 UE需要将 BSR分别发送到对应的宏基站或至少一个小基站, 此时, 当 UE需要发送宏基 站对应的 BSR, UE只需计算与宏基站对应的每个逻辑信道组的第一緩存数据 量, 并向宏基站发送与第一緩存数据量对应的 BSR; 当 UE需要发送一个小基
站的 BSR, UE只需计算与该小基站对应的每个逻辑信道组的緩存数据量, 并 向该小基站发送与该緩存数据量对应的 BSR。 如果 UE需要将宏基站和 /或至少 一个小基站对应的 BSR集中发送到其中一个站点, 当 UE需要向宏基站或一个 小基站发送宏基站和 /或至少一个小基站触发的 BSR, 则 UE需计算与触发 BSR 的宏基站和 /或至少一个小基站对应的每个逻辑信道组对应的緩存数据量, 并 向宏基站或一个小基站发送触发了 BSR的宏基站和 /或至少一个小基站的 BSR, 这里, 多个站点对应的 BSR可以组合发送, 也可以单独发送。
本实施例提供的緩存状态报告发送方法, 通过 UE接收宏基站发送的每个 业务的分流比例信息, 根据每个业务的分流比例信息, 采用 ¾Bi * Mi计算获取 第一緩存数据量, 采用 Bi*Si计算获取至少一个小基站对应的每个逻辑信道 组的緩存数据量, 这里每个小基站的 Si可能不同, 然后 UE向宏基站发送与第 一緩存数据量对应的 BSR和 /或向至少一个小基站发送与小基站对应的每个逻 辑信道组的緩存数据量对应的 BSR, 或者, 向宏基站发送与第一緩存数据量对 应的 BSR和 /或与至少一个小基站的每个逻辑信道组的緩存数据量对应的 BSR 或向至少一个小基站发送与第一緩存数据量对应的 BSR和 /或与至少一个小基 站的每个逻辑信道组的緩存数据量对应的 BSR。 实现了 UE可根据每个业务的 分流比例信息准确获知 UE上报的緩存状态报告, 从而小基站和宏基站可以及 时进行调度。 作为另一种可实施的方式: UE接收宏基站发送的每个业务对应的逻辑信 道优先次序的参数信息,逻辑信道优先次序的参数信息用于指示向宏基站和至 少一个小基站分别传输的数据量, UE接收到每个业务对应的逻辑信道优先次 序的参数信息后, 根据逻辑信道优先次序的参数信息, 确定分流比例, 并根据 分流比例, 确定与宏基站对应的每个逻辑信道组的第一緩存数据量和 /或与至
少一个小基站对应的每个逻辑信道组的緩存数据量, 具体地, 采用
^ PBRmi* BSDmi
Bi *
^ PBRmi *BSDmi + PBRsi*BSDsi 计算获取第 一緩存数据量 , 采用
少一个小基站对应的每个逻辑信 道组的緩存数据量, 其中, PBRmi、 BSDmi分别为逻辑信道优先次序的参数信 息中 UE向宏基站传输的优先比特速率(Prioritised Bit Rate, 简称: PBR )、 存 储桶量时间 ( Bucket Size Duration, 简称: BSD ) , PBRsi、 BSDsi分别为逻辑 信道优先次序的参数信息中 UE向小基站传输的优先比特速率、存储桶量时间, 如果有多个小基站,则每个小基站对应的 PBRi和 BSDi可能不同, N为逻辑信道 组 LCG中的业务个数, Bi为每个业务对应的当前緩存数据量。
然后 UE向宏基站发送与第一緩存数据量对应的 BSR和 /或向至少一个小基 站发送与小基站对应的每个逻辑信道组的緩存数据量对应的 BSR, 或者, 向宏 基站发送与第一緩存数据量对应的 BSR和 /或与至少一个小基站的每个逻辑信 道组的緩存数据量对应的 BSR, 或者, 向至少一个小基站发送与第一緩存数据 量对应的 BSR和 /或与至少一个小基站的每个逻辑信道组的緩存数据量对应的 BSR, 此时, 比如 UE向宏基站发送与第一緩存数据量对应的 BSR和 /或与至少 一个小基站的每个逻辑信道组的緩存数据量对应的 BSR,宏基站接收到之后可 以将与至少一个小基站的每个逻辑信道组的緩存数据量对应的 BSR转发给小 基站, 如果 UE向至少一个小基站发送与第一緩存数据量对应的 BSR和与至少 一个小基站的每个逻辑信道组的緩存数据量对应的 BSR,小基站接收到之后可 以将与宏基站对应的每个逻辑信道组的第一緩存数据量对应的 BSR转发给宏 基站。
本实施例提供的緩存状态报告发送方法, 通过 UE接收宏基站发送的每个 业务对应的逻辑信道优先次序的参数信息, 根据逻辑信道优先次序的参数信 息, 采用 PBRmi ^BSDmi 计算获取第一緩存数据量, 采用
PBRmi * BSDmi + PBRsi*BSDsi
¾Bi * PBRsi* BSDsi 计算获取至少一个小基站对应的每个逻辑信 PBRmi * BSDmi + PBRsi*BSDsi 道组的緩存数据量, 然后 UE向宏基站发送与第一緩存数据量对应的 BSR和 /或 向至少一个小基站发送与小基站对应的每个逻辑信道组的緩存数据量对应的
BSR,或者, 向宏基站发送第一緩存数据量对应的 BSR和 /或与至少一个小基站 的每个逻辑信道组的緩存数据量对应的 BSR或向至少一个小基站发送与第一 緩存数据量对应的 BSR和 /或与至少一个小基站的每个逻辑信道组的緩存数据 量对应的 BSR。 实现了 UE可根据每个业务对应的逻辑信道优先次序的参数信 息准确获知 UE上报的緩存状态报告,从而小基站和宏基站可以及时进行调度。 图 3为本发明緩存状态报告接收方法实施例一的流程图,如图 3所示, 本实 施例的方法可以包括:
步骤 201、 宏基站向用户设备 UE发送用于请求 UE发送緩存状态报告的指 示信息。
步骤 202、 宏基站接收 UE根据指示信息发送的緩存状态报告 BSR, 宏基站 和至少一个小基站共同服务于 UE, 宏基站的服务范围大于至少一个小基站中 每个小基站的服务范围。
在步骤 201中,宏基站向用户设备 UE发送的指示信息包括指示在每个业务 向宏基站和至少一个小基站分别传输的数据量的信息。 指示信息还包括指示 BSR的接收基站的信息, BSR的接收基站包括宏基站和 /或至少一个小基站。宏 基站向用户设备 UE发送指示信息之后还可包括向 UE发送用于变更 BSR的接收 基站的更新信息, 变更后的接收基站包括宏基站和 /或至少一个小基站。 其中 指示信息或更新信息可以是 RRC信令、 广播消息、 MAC控制信令、 物理层的 控制信令中的一种,指示信息和更新信息还可以是一个 RRC信令或一条广播消
息或一个 MAC控制信令或一个物理层的控制信令。
在本实施例 201中, 宏基站向用户设备 UE发送指示信息, 本实施例中有两 种实施方案, 作为一种可实施的方式: 宏基站向 UE发送每个业务对应的分流 比例信息,分流比例信息用于指示向宏基站和至少一个小基站分别传输的数据 量, 需要说明的是, 宏基站为 UE配置每个业务的分流比例信息, 宏基站可能 是一次配置多个业务的分流比例信息,也可能是一次只配置一个业务的分流比 例信息, 分多次配置。 然后宏基站接收 UE发送的与宏基站对应的每个逻辑信 道组的第一緩存数据量对应的 BSR, 或者, 接收 UE发送的与宏基站对应的每 个逻辑信道组的第一緩存数据量对应的 BSR和 /或与至少一个小基站的每个逻 辑信道组的緩存数据量对应的 BSR, 此时若宏基站接收到 UE发送的与宏基站 对应的每个逻辑信道组的第一緩存数据量对应的 BSR和 /或与至少一个小基站 的每个逻辑信道组的緩存数据量对应的 BSR,可以将与至少一个小基站的每个 逻辑信道组的緩存数据量对应的 BSR转发给小基站。第一緩存数据量和小基站 的每个逻辑信道组的緩存数据量为 UE根据每个业务对应的分流比例信息确定 的。 BSR中还包括 LCID或基站序号, LCID用于标识需要转发的 BSR, 基站序 号用于标识 BSR需要被转发的目的基站。
