在一种常见的应用场景下, 在多用户 MIMO (Mul t i-User MIMO, MU-MIMO) 系统的用户终端可以安装一个天线, 基站安装多个天线, 由于基站下有多个 用户终端, 因此基站可将多个用户终端进行匹配组成一个多天线终端组, 然 后传输数据。
多天线终端组的组成是 MU-MIMO技术中的重要步骤, 首先选定若干已调 度用户终端。 然后从剩下的用户终端中选取 N-1 个未调度用户终端; N 为 MU-MIMO 系统允许匹配的最大用户终端数; 选取一个已调度用户终端和选取 的 N-1个用户终端按照预设定配对规则完成匹配,组成一个多天线终端组。 按 照上述方法, 可为其它已调度用户终端配对。
在实际应用中, 一个用户终端有多个业务, 每个业务对单位时间内传输 的数据量即数据传输速率有不同要求, 比如通话业务需要实时传输数据, 需 要较高的数据传输率; 邮件业务仅需在规定的时间内完成即可, 对数据传输 率要求较小。对数据传输率要求较高的业务来说,即 GBR (Guaranteed Bi t Rate 保证比特率)业务, 必须要保证一个最低数据传输率, 否则会降低业务质量, 比如对于实时通话业务来说, 会出现语音出现断断续续的情况。 现有技术中, 组成的多天线终端组不能保证 GBR业务的数据传输率, 影响业务服务质量。 发明内容
本发明的实施例提供一种数据传输的方法和基站, 解决现有技术中组成 的多天线终端组不区分用户终端的业务类型, 即不能保证 GBR 业务的数据传 输率, 影响业务服务质量的技术问题。

为了更清楚地说明本发明实施例或现有技术中的技术方案, 下面将对实 施例或现有技术描述中所需要使用的附图作简单地介绍, 显而易见地, 下面 描述中的附图仅仅是本发明的一些实施例, 对于本领域普通技术人员来讲, 在不付出创造性劳动性的前提下, 还可以根据这些附图获得其他的附图。
图 1为本发明实施例 1中一种数据传输的方法的流程图;
图 2为本发明实施例 2中一种数据传输的方法的流程图;
图 3为本发明实施例 2中一种数据传输的方法的流程图;
图 4为本发明实施例 3中一种基站的框图;
图 5为本发明实施例 3中调度单元的框图;
图 6为本发明实施例 4中一种基站的示意图。 具体实施方式 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做 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。
本发明的技术方案, 可以应用于各种通信系统, 例如: 全球移动通信系 统(GSM, Global System for Mobile Communications ) ,码分多址接入(CDMA, Code Division Multiple Access )系统, 宽带码分多址接入( WCDMA, Wideband Code Division Multiple Access )系统,长期演进( LTE, Long Term Evolution ) 系统等。
用户终端 (UT, User Terminal ) 也可称之为用户设备 ( UE, User Equipment )、移动终端(MT, Mobile Terminal )、移动台(MS, Mobile Station ) 等, 可以经无线接入网 (例如, RAN, Radio Access Network )与一个或多个 核心网进行通信。
基站,可以是 GSM或 CDMA中的基站(BTS, Base Transceiver Station) , 也可以是 WCDMA中的基站(称为 Node B ) , 还可以是 LTE中的演进型基站(称 为 eNB或 e_NodeB, evolutional NodeB ) 。 另外, 一个基站可能支持 /管理一 个或多个小区 (cell ) , 用户终端需要和网络通信时, 它将选择一个小区发 起网络接入。
GBR (Guaranteed Bit Rate,保证比特率)业务是实际传输速率必须高于 规定传输速率的业务, 否则会出现业务质量不能满足客户需求的现象, 实时 通话业务是典型的 GBR 业务, 假如该业务的规定传输速率是 100kb/s (kilobyte/second,千字节 /秒), 实际传输速率是 80 kb/s , 则在通话 过程中, 用户可能只能听到断断续续的声音。
需要说明的是, 本发明实施例中所说的配对操作不限于两个用户, 可以 泛指多个用户; 用户终端是指接入基站的用户终端, 包括已调度用户终端和 未调度用户终端。
实施例 1: 本发明的一个实施例提供一种数据传输的方法, 如图 1 所示, 包括如下 步骤:
101、 从已调度用户终端中选取一个第一待匹配用户终端。
已调度用户终端是基站已经分配了用于传输数据的信道及进行了相应设 置的用户终端。 第一待匹配用户终端为已调度用户终端。
102、 判断所述第一待匹配用户终端的业务类型。
第一待匹配用户终端的业务类型有两种, 一种是 GBR (Guaranteed Bi t Ra te,保证比特率)业务, 另一种是 Non_GBR (Non-Guaranteed Bi t Ra te,非保 证比特率)业务。 QOS ( Qua l i ty Of Service , 服务质量)是根据用户终端的 不同业务对传输速率的不同要求而进行的规定, 包括信道质量指示、 业务优 先级,数据包的时延,丟包率,资源类型等。其中资源类型分为 GBR和 Non-GBR。 QOS 在各个传输协议中, 如 LTE ( Long Term Evolut ion,长期演进)协议和 LTE-A (Long Term Evolut ion-Advanced,后续长期演进)协议等, 有详细规定。 步骤 102的实现方式可以是: 根据第一待匹配用户终端 Q0S的资源类型获取 第一待匹配用户终端的业务类型, 然后判断第一待匹配用户终端的业务类型 是 GBR业务还是 Non-GBR业务。
103、 当所述第一待匹配用户终端的所述业务类型是 Non-GBR业务时, 从 未调度用户终端中选取 N-1个第二待匹配用户终端, 其中 N为系统允许配对 的用户终端的总数, 且大于或等于 2。
104、 将 N-1个第二待匹配用户终端与第一待匹配用户终端进行配对, 组 成多天线终端组。
105、 进行多天线终端组的数据传输。
本实施例提供一种数据传输的方法, 首先, 从已调度用户终端中选取一 个第一待匹配用户终端, 然后判断所述第一待匹配用户终端的业务类型; 当 所述第一待匹配用户终端的所述业务类型是 Non-GBR业务时, 将 N-1个第二 待匹配用户终端与所述第一待匹配用户终端进行配对, 以便基站将所述第一 待匹配用户终端和所述 N-1 个第二待匹配用户终端组成多天线终端组进行数 据传输。 通过上述方案, 阻止 GBR业务的用户终端进行配对, 提高了业务的 服务质量。
实施例 2:
本发明的一个实施例提供一种数据传输的方法, 如图 2 所示, 包括如下 步骤:
201、 从已调度用户终端中选取一个第一待匹配用户终端。
202、 判断所述第一待匹配用户终端的业务类型。
根据 Q0S判断第一待匹配用户终端的业务类型是 GBR业务还是 Non-GBR 业务。
实现步骤 202 的具体方式可以是, 将第一待匹配用户终端向基站发送的 业务请求与传输协议中规定的业务进行匹配, 与业务请求相匹配的业务为第 一待匹配用户终端的业务。 然后查看所述第一待匹配用户终端的业务的资源 类型是 GBR业务或 Non-GBR业务。
203、 当所述第一待匹配用户终端的所述业务类型是 GBR业务时, 指示所 述第一待匹配用户终端使用已经分配的信道单独进行数据传输。
GBR业务是实际传输速率必须高于规定传输速率的业务,否则会出现业务 质量不能满足客户需求的现象, 实时通话业务是典型的 GBR业务, 假如业务 的规定传输速率是 100kb/ s (k i lobyte/ s econd,千字节 /秒), 实际传输速率是 80 kb/ s , 则在通话过程中, 用户可能只能听到断断续续的声音。
根据 MU-MIM0系统的原理可知: 第一待匹配用户终端与 N-1个第二待匹 配用户终端进行配对后, 将第一待匹配用户终端与 N-1 个第二待匹配用户终 端作为一个整体进行数据传输, 这样可以提高单位时间内基站的数据吞吐量, 即基站的传输速率, 所述 N为系统允许配对的用户终端的总数, 且大于或等 于 2。但这需要牺牲第一待匹配用户终端的传输速率。 当包含 GBR业务的用户 终端 A ( H没用户终端 A为第一待匹配用户终端 )进行配对后, 则用户终端 A 的传输速率会降低, 若低于用户终端 A的 GBR业务规定的传输速率时, 则该 GBR业务就不能满足服务要求。 为消除这一缺陷, 故需要阻止包含 GBR业务的 第一待匹配用户终端进行 MU-MIM0配对。 进一步的, 还提供一种数据传输的方法, 如图 3 所示, 该方法包括如下 步骤:
301、 从已调度用户终端中选取一个第一待匹配用户终端。
在从已调度用户终端中选取第一待匹配用户终端的方式既可以随机选 取, 也可以按照用户终端在终端组的顺序依次选取, 本实施例不做限定。
302、 判断所述第一待匹配用户终端的业务类型。
根据 Q0S判断第一待匹配用户终端的业务类型。
当第一待匹配用户终端的业务类型是 GBR业务时, 执行步骤 303。
当第一待匹配用户终端的业务类型是 Non-GBR业务时, 执行步骤 304。
303、 当所述第一待匹配用户终端的所述业务类型是 GBR业务时, 指示所 述第一待匹配用户终端使用已经分配的信道单独进行数据传输, 即 SU-MIM0 传输。
304、 当所述第一待匹配用户终端的所述业务类型是 Non-GBR业务时, 从 未调度用户终端中选取 N-1个第二待匹配用户终端。
第一待匹配用户终端为已经分配用于传输数据的信道的用户终端, N-1个 第二待匹配用户终端是没有分配用于传输数据的信道的用户终端, N为系统 允许配对的用户终端的总数, 且大于或等于 2。
选取 N-1 个第二待匹配用户终端的方法既可以随机选取, 也可以按照用 户终端在终端组的顺序依次选取, 本实施例不 ^1限定。
305、 判断第一待匹配用户终端和 N-1个第二待匹配用户终端的预配对后 的业务总速率是否高于第一待匹配用户终端的业务速率。
第一待匹配用户终端的业务速率是指第一待匹配用户终端进行 SU-MIM0 数据传输时的业务速率。
步骤 305的判断条件, 是为了保证配对组成的多天线终端组的业务总速 率要高于第一待匹配用户终端的业务速率。 即只有在满足步骤 305 的判断条 件后才能够组成多天线终端组, 使用户终端以多天线终端组为单位一起实现 与基站间的数据发送和接收。
显然步骤 305 中一共选择了 N个用户终端 (1个第一待匹配用户终端和 N-l个第二待匹配用户终端)。
下面说明获取预配对后的业务总速率的过程:
根据先验信息, 对选择的 N个用户终端进行 MU-MIM0预配对, 计算第一 待匹配用户终端预配对后的业务速率以及所述 N个用户终端预配对后的总业 务速率。
第一待匹配用户终端预配对后的业务速率是指所述第一待匹配用户终端 与所述 N-1 个第二待匹配用户终端组成多天线终端组后, 所述第一待匹配用 户终端的业务速率。
N 个用户终端预配对后的总业务速率是指所述第一待匹配用户终端与所 述 N-1个第二待匹配用户终端在预配对后的业务速率之和, 即步骤 305所述 的业务总速率。
第一待匹配用户终端预配对后的业务速率以及所述 N个用户终端预配对 后的业务总速率都记录在基站提供的数据表中。
特殊情况下,Ν的取值为 2 , 此时的情况是, 一个第一待匹配用户终端与 一个第二待匹配用户终端进行预配对。 更普通的情况是, Ν的取值大于 2 , 即 与 2个以上的用户终端进行预配对。
系统提供的数据表上记录了计算得到的用户终端进行 SU-MIM0传输的业 务速率和预配对后的业务速率。 选定的第一待匹配用户终端的业务速率是所 述用户终端在进行 SU-MIM0 的传输速率。 实际应用场景中, 所述数据表存储 在基站中, 可以按照需要随时获取记录在数据表中的数据。
现举例说明, 步骤 305的判断过程。 设第一待匹配用户终端为 Α, 系统允 许配对的第二待匹配用户终端数为 2 (即 Ν=3 ), 第二待匹配用户终端 Bl , Β2。 在 MU-MIM0 系统控制协议提供的数据表中查到: 用户终端 Α 的业务速率为 10000比特 /秒,预配对后业务速率为 6200比特 /秒; 用户终端 B1的预配对后 的业务速率为 3200比特 /秒, 用户终端 B2的预配对后的业务速率为 3600比 特 /秒。 经判断, 第一待匹配用户终端 A的业务类型是 Non-GBR业务, 则将 A 与 N-1个第二待匹配用户终端进行预配对。 A和 N-1个第二待匹配用户终端 Bl , B2的预配对后的业务总速率为 6200+3200+3600=13000比特 /秒。步骤 305 具体到本例中就是判断所述总速率 1 3000比特 /秒与第一待匹配用户终端 A预 配对前的速率 10000比特 /秒的大小。 显然, 本例中的总速率大于用户终端 A 预配对前的速率, 应该执行步骤 306。
当第一待匹配用户终端和 N-1 个第二待匹配用户终端的预配对后的业务 总速率高于所述第一待匹配用户终端的业务速率时, 执行步骤 306。
当第一待匹配用户终端和 N-1 个第二待匹配用户终端的预配对后的业务 总速率不高于所述第一待匹配用户终端的业务速率时, 执行步骤 307。
306、 将第一待匹配用户终端和 N-1个第二待匹配用户终端进行配对, 以 便基站将第一待匹配用户终端和 N-1 个第二待匹配用户终端, 然后进行多天 线终端组的数据传输。
307、 如果第一待匹配用户终端和 N-1个第二待匹配用户终端的预配对后 的业务总速率不高于所述第一待匹配用户终端的业务速率, 重新选择除所述 N-1个第二待匹配用户终端之外的其它 N-1个所述第二待匹配用户终端进行配 对。
当步骤 307所述的判断条件成立时, 重新选择 N-1个第二待匹配用户终 端, 然后执行步骤 305。 当第二终端组中的所有用户终端均参与预配对后, 仍 不能找到 N-1 个第二待匹配用户终端与第一待匹配用户终端的预配对后的业 务总速率大于第一待匹配用户终端的业务速率, 即不满足步骤 305 的判断条 件, 则第一待匹配用户终端只能进行 SU-MIM0传输。
举例说明步骤 301至 307 , 设第一待匹配用户终端 A , 第二待匹配用户终 端为 B, C, D, E, F, G。系统允许进行 MU-MIM0配对的第二待匹配用户终端的数量 为 2 , 即 N=3。 经判断, 第一待匹配用户终端 A的业务类型是 Non-GBR业务, 则首先将 A与 B, C进行预配对, 若 A, B, C的预配对后的业务总速率不高于 A 的业务, 则重新选择除所述 N-1个第二待匹配用户终端之外的其它 N-1个所 述第二待匹配用户终端进行所述配对, 即选取 D, E进行预配对。 由于 B, C 已 经参与预配对, 故此次预配对可选择的对象为 D, E , F , G。 若 A, D, E的预配 对后的业务总速率高于 A的业务, 则将 A, D, E进行配对。 A的业务速率是指用 户终端 A进行 SU-MIM0传输时的数据, 在本例中, 可以理解为预配对前的业 务速率。
需要说明的是, 选取 N-1 个第二待匹配用户终端的方式可以是按照先后 顺序选取, 也可是随机选取, 本实施例不做限定。
本实施例提供一种数据传输的方法, 首先选取一个第一待匹配用户终端, 然后根据服务质量 Q0S判断所述第一待匹配用户终端是 GBR业务还是 Non-GBR 业务, 一方面, 阻止业务类型是 GBR业务的第一待匹配用户终端进行配对, 另一方面, 将业务类型是 Non-GBR 业务的第一待匹配用户终端与 N-1个第二 待匹配用户终端进行配对。 通过上述方案, 区分用户终端的业务类型, 对用 户终端进行配对, 一方面, 保证包含 GBR业务的第一待匹配用户终端的传输 速率, 另一方面, 保证 Non-GBR业务的第一待匹配用户终端与 N-1个第二待 匹配用户终端的整体传输速率, 提高了业务的服务质量。
