附图说明 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一简单地介绍, 显而易见地, 下面描述中的附图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 2为本发明另一实施例提供的数据传输方法的流程图。
图 3为本发明一实施例提供的基站的结构示意图。
图 4为本发明另一实施例的基站的结构示意图。
图 5为本发明一实施例提供的 UE的结构示意图。
图 6为本发明一实施例提供的数据传输系统的结构示意图。
具体实施方式 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。
应理解, 本发明的技术方案可以应用于各种通信系统, 例如: 全球移 动通讯(GSM, Global System of Mobile communication ) 系统、 码分多址 ( CDMA, Code Division Multiple Access )系统、 宽带码分多址( WCDMA, Wideband Code Division Multiple Access )系统、通用分组无线业务 ( GPRS, General Packet Radio Service )、长期演进 ( LTE, Long Term Evolution )系统、 先进的长期演进( LTE-A, Long Term Evolution Advanced ) 系统、 通用移动 通信系统 ( UMTS, Universal Mobile Telecommunication System )等, 本发 明实施例并不限定, 但为描述方便, 本发明实施例将以 LTE网络为例进行 说明。 的系统中可包括不同的网元。 例如, LTE和 LTE-A中无线接入网络的网元 包括 eNB ( eNodeB , 演进型基站), WCDMA ( Wideband Code Division Multiple Access , 宽带码分多址) 中无线接入网络的网元包括 RNC ( Radio Network Controller,无线网络控制器)和 NodeB,类似地, WiMax( Worldwide Interoperability for Microwave Access , 全球 波互联接入 )等其它无线网络 也可以使用与本发明实施例类似的方案, 只是基站系统中的相关模块可能 有所不同,本发明实施例并不限定,但为描述方便,下述实施例将以 eNodeB 为例进行说明。
还应理解, 在本发明实施例中, 用户设备(UE, User Equipment )也可 称之为终端、 移动台 (MS, Mobile Station ), 移动终端 ( Mobile Terminal ) 等, 该用户设备可以经无线接入网 (RAN, Radio Access Network ) 与一个 或多个核心网进行通信, 例如, 用户设备可以是移动电话 (或称为"蜂窝" 电话)、 具有通信功能的计算机等, 例如, 用户设备还可以是便携式、 袖珍 式、 手持式、 计算机内置的或者车载的移动装置。
在 LTE通信系统中,基站综合考虑 LTE通信系统可用的资源、 LTE通 信系统中的 UE数量以及各个 UE待传输的业务量可以确定出每个 UE能够 使用的 PRB数量。 该 PRB数量即相当于本发明下述实施例中的"第一 PRB 数量"。 另外, 基站依据 UE反馈信道质量指示 ( Channel Quality Indicator; CQI )信息或者以基站自行决策的方式能够确定在 UE与基站的传输过程中 釆用的调制编码方式。 当基站向要向 UE发送数据时,基站通过控制信道在 告诉 UE基站向 UE发送数据所釆用的调制编码方式以及 PRB数量; 同时 在共享信道上向 UE发送数据。这样 UE接收控制信道上的调制编码方式以 及 PRB数量,并根据调制编码方式以及 PRB数量接收基站在共享信道上发 送的数据。 而当 UE向基站发送数据时,也可以根据该调制编码方式以及该 PRB数量在共享信道上向基站发送数据。
图 1为本发明一实施例提供的数据处理方法的流程图。 如图 1所示, 本实施例的数据处理方法的执行主体为基站。 本实施例的数据处理方法, 具体可以包括如下步骤:
100、 基站根据第一 PRB数量获取第二 PRB数量;
本实施例中的第二 PRB数量小于第一 PRB数量, 且第二 PRB数量能 够被第一 PRB数量整除。本实施例中的第一 PRB即为现有技术中的 PRB 。
101、 基站向用户设备 ( User Equipment; UE )发送指示信息; 该指示 信息用以指示第二 PRB数量或者编码后的比特重复的倍数, 其中该编码后 的比特重复的倍数等于第一 PRB数量除以第二 PRB数量。
例如, 该指示信息以供 UE根据指示信息获取编码后的比特重复的倍 数,并根据编码后的比特重复的倍数进行数据传输,详见下述 UE侧实施例 的记载。
本实施例中 UE根据编码后的比特重复的倍数进行数据传输,具体可以 为 UE根据编码后的比特重复的倍数进行数据发送或者数据接收。 例如 UE 可将编码后的比特重复上述编码后的比特重复的倍数后发送;或者 UE在获 知已收到的数据中存在已知的上述编码后的比特重复的倍数的重复时, 将 解码前的软比特信息中的重复信号进行合并, 例如进行最大比合并或者等 增益合并, 再将合并后的软比特信息送入解码器进行解码, 实现对数据的 接收。
本实施例的数据传输方法,通过釆用上述技术方案,基站根据第一 PRB 数量获取第二 PRB数量, 并向 UE发送用以指示编码后的比特重复的倍数 或者第二 PRB 数量的指示信息, 编码后的比特重复的倍数等于所述第一 PRB数量除以第二 PRB数量; 并由 UE根据指示信息获取编码后的比特重 复的倍数, 并根据编码后的比特重复的倍数进行数据传输。 相对于现有技 术的最低可以达到的编码率为 0.1相比, 本实施例的技术方案,根据编码后 的比特重复的倍数进行数据传输, 从而能够进一步降低编码率, 实现小于 0.1的编码率的数据传输, 进而能够进一步增强无线通信系统的最大覆盖能 力。
可选地, 上述图 1所示实施例中的步骤 101之后, 还可以包括如下步 骤:
基站接收 UE发送的数据,该数据为 UE根据编码后的比特重复的倍数 进行传输的。
具体地, 在步骤 101中基站向 UE发送指示信息之后, UE可以根据指 示信息获取编码后的比特重复的倍数, 并根据编码后的比特重复的倍数进 行数据传输, 例如 UE根据编码后的比特重复的倍数向基站传输数据。
可选地, 上述图 1所示实施例中的步骤 100"基站才艮据第一物理资源块 数量获取第二物理资源块数量",具体可以包括:基站从预设的第一 PRB数 量与至少一个第二 PRE数量的对应关系表中, 获取上述第二 PRB数量; 其 中至少一个第二 PRB数量中每个第二 PRB数量均能够被第一 PRB数量整 除。
进一步可选地, 在上述 "基站从预设的第一 PRB 数量与至少一个第二 PRB数量的对应关系表中, 获取上述第二 PRB数量"之前, 还可以包括: 基站建立第一 PRB数量和至少一个第二 PRB数量的对应关系表。该对 应关系表中, 每一个第一 PRB数据量对应至少一个第二 PRB数量。
为了更加清楚的描述第二 PRB数量和第一 PRB数量之间的对应关系, 下面以现有技术中的第一 PRB数量从 1到 110为例,详细分析第一 PRB数 量分别为 1到 110中的任意一个数值时, 对应的能够被整除的至少一个第 二 PRB数量, 详见下述表 1。 即下述表 1中的每一个第一 PRB数量与其对 应的至少一个第二 PRB数量可构成第一 PRB与其对应的至少一个第二 PRB 数量的对应关系表。 下述表 1可以认为包括了第一 PRB数量从 1到 110所 对应的对应关系表。 表 1

在基站侧, 根据上述表格, 可以获取每一个第一 PRB数量对应的至少 一个第二 PRB数量, 该至少一个第二 PRB数量构成一个第二 PRB数量集 合, 可以在该第二 PRB数量集合中获取任一个第二 PRB数量。
进一步可选地, 实际应用中,也可以根据实际需求获取第二 PRB数量, 例如基站可以根据期望达到的编码率与现有技术条件下能够达到的编码率 (例如, 在现有技术条件下已经选择了最低阶调制编码方式后得到的编码 率约为 0.1 )相比较获取编码后的比特重复的倍数, 即取现有编码率除以期 望达到的编码率(例如当倍数不是整数时,可以对倍数向上或者向下取整)。 例如取现有最低编码率除以期望达到的编码率得到的倍数为 4,例如此时第 一 PRB数量为 84,则此时需要取第二 PRB数量为 84/4=21。需要说明的是, 如果实际需要的重复倍数为 5, 而候选的重复倍数仅有 4或者 6的情况下, 可以有如下方案: 1。任选重复倍数 4或者 6;或者还可以通过调整第一 PRB 数量来选择满足需要的重复倍数(例如, 更改第一 PRB数量为 85后, 可以 选择重复倍数为 5 ) 。
在上述表 1中, 第二 PRB数量最多为第一 PRB数量为 84时, 此时对 应的第二 PRB数量为 13个。 且当上述实施例中的指示信息用于指示第二 PRB数量时, 此时需要 4比特的指示信息来指示第二 PRB数量。 如下表 2 为第一 PRB数量为 84时对应的第二 PRB数量和对应的指示信息的情况。 上述表 2中的指示信息为 4比特。 实际应用中如表 1所示, 当第二 PRB数 量较小时, 也可以釆用小于 4比特的指示信息来指示。
表 2
Figure imgf000011_0001
上述表 2中指示信息和对应的用于指示的第二 PRB数量之间的对应关 系,可以预先在基站与 UE之间定义(不限于上述表 2的对应关系),这样, 当 UE接收到基站的指示信息,便可以根据该指示信息便可以确定该指示信 息用以指示的第二 PRB数量。
当上述图 1所示实施例中的步骤 101中,基站向 UE发送的指示信息用 于指示第二 PRB数量时, 同时基站还会按照相关现有技术的方式向 UE指 示第一 PRB数量。 这样, 基站可以根据第一 PRB数量和第二 PRB数量获 取编码后的比特重复的倍数(即将第一 PRB数量除以第二 PRB数量所得的 倍数) , 然后便可以根据编码后的比特重复的倍数进行数据传输。
但是, 考虑到增加指示信息的比特对于指示信息的传输带来了较大的 压力, 因此可以将每种第一 PRB数量对应的第二 PRB数量集合进行压缩, 例如对于给定的指示信息的比特数确定保留的第二 PRB数量, 如当指示信 息为 3比特, 可知在第二 PRB数量集合中最多包含 η=8种选择。 依然以第 一 PRB数量为 84为例, 当指示信息的比特数为 3时, 对应的第二 PRB数 量和对应的指示信息的情况如表 3所示。 实际应用中, 表 3所示的指示信 息用于指示第二 PRB数量的集合中的哪个第二 PRB数量,可以根据实际需 求情况来设置在此不再限制。 表 3
Figure imgf000012_0001
需要说明的是, 在上述图 1 所示的实施例中, 指示信息还用于指示编 码后的比特重复的倍数, 此时上述图 1所示实施例中的步骤 101"基站获取 用以指示第二 PRB数量或者编码后的比特重复的倍数的指示信息",具体指 的是基站获取用以指示第二 PRB数量的指示信息, 或者基站获取用以指示 编码后的比特重复的倍数的指示信息。 当基站获取用于指示第二 PRB数量 的指示信息时, 可以釆用上述表 2或者表 3的方式获取用于指示第二 PRB 数量的指示信息。
当基站获取用以指示编码后的比特重复的倍数的指示信息时, 上述实 施例中的步骤 101具体可以包括如下步骤:
( 1 )基站根据第一 PRB数量和第二 PRB数量获取编码后的比特重复 的倍数;
( 2 )基站获取编码后的比特重复的倍数对应的指示信息。 如下表 4仍然以第一 PRB数量为 84为例,对应表 3中的各个第二 PRB 数量算出来的编码后的比特重复倍数以及对应的指示信息的情况。
表 4
Figure imgf000013_0001
同理,编码后的比特重复倍数与指示信息的对应关系可以由 UE和基站 之间预先定义,这样 UE接收到基站发送的指示信息之后,可以根据该指示 信息确定对应的编码后的比特的重复倍数。
可选地, 在上述图 1 所示实施例的基础上, 其中步骤 102"基站向 UE 发送指示信息", 具体可以包括如下步骤:
( a )基站在下行控制信息( Downlink Control information; DCI ) 中增 加字段; 并在增加的字段中携带指示信息;
( b )基站向 UE发送携带指示信息的 DCI。
进一步可选地, 上述实施例中的指示信息的长度范围为 0-4比特。
上述实施例的数据传输方法, 通过釆用上述技术方案, 能够使得 UE 根据编码后的比特重复的倍数进行数据传输, 从而能够进一步降低编码率, 实现小于 0.1的编码率的数据传输,进而能够进一步增强无线通信系统的最 大覆盖能力。
图 2为本发明另一实施例提供的数据传输方法的流程图。 如图 2所示, 本实施例的数据处理方法的执行主体为 UE。 如图 2所示, 本实施例的数据 处理方法, 具体可以包括如下步骤:
