Description

一种***信息传输方法和装置
技术领域
本申请涉及通信技术领域, 具体涉及一种***信息传输方法和装置。 背景技术
***信息主要用于表征一个无线小区的相关参数, 被添加在***信息块
SIB (System Information Block)中, 由基站在空中接口上以周期性广播的方式, 将***信息下发给小区中的用户设备 (User Equipment, UE) , 以使 UE根据 接收到的***信息确定驻留小区时采用的参数设置。
由于广播信道必须按照固定大小的传输块传输数据, 因此, 为了保证系 统信息块的大小满足广播信道的要求, 网络侧需要按照广播信道的要求, 对 ***信息块进行分割和 /或級联处理得到符合要求的传输块。一个传输块中可 能会包含多个不同类型的***信息块, 称之为***信息子块。 为了正确的表 征一个传输块的内容, 在传输块中除了数据之外, 还会包含一些***信息子 块的头信息, 例如, ***信息块类型 (SIB type) 占用 5bit, 分割总块数 (SEG_COUNT)或者分割块编号(Segment index) 占用 4bit,对于一个 246bits 的传输块来说, 所述头信息会占用传输块的部分比特位, 导致一个传输块中 的包含的有效数据较少, 数据传输效率低。 尤其是, 当***信息块被分割成 多个传输块时, 每个传输块中都要包含部分头信息, 致使数据传输效率低的 问题更为明显。
随着通信***的演进, 越来越多的信息需要以***信息块的形式广播给 UE ,若采用现有的***信息块的广播方式,广播信道承载的有效信息就越少, 头信息越多, 如此就导致 SIB广播周期越来越长。 由于 UE要根据基站广播 的 SIB确定驻留小区的参数设置, 若 SIB广播周期延长, 那么 UE的接入时 延也就会相应延长, 如此势必会降低用户使用体验。 发明内容

为了使本技术领域的人员更好地理解本发明实施例的方案, 下面结合附 图和实施方式对本发明实施例作进一步的详细说明。
参见图 1, 示出的本发明实施例***信息传输方法的实施例 1的流程图, 所述方法包括:
步驟 101,基站按照预设条件选择至少一种类型的***信息块作为待处理 ***信息块。
步驟 102, 所述基站才艮据广播信道的传输需求,对所述待处理***信息块 进行分割和 /或級联处理得到传输块,所述传输块中包含至少一种类型的*** 信息子块, 所述***信息子块包括: 头部域和数据域。
随着通信***的演进, 不同版本的通信***包含不同类型的***信息块, 下面仅以 WCDMA(Wideband Code Division Multiple Access , 宽带码分多址)通 信*** R5版本为例, 对该步驟进行解释说明。 WCDMA*** R5版本中, 不 考虑各***信息的扩展 (例如: SIBl lbis等) 总共有 18种类型的***信息块 (System Information Block , SIB) , 分别标识为 SIB1〜SIB18。 SIB在 BCCH信道上周期性广播, SIB 包括接入网络和核心网的公共信 息, 核心网的信息包括运营商信息、 鉴权等信息; 接入网的信息包括位置登 记区、 小区、 公共信道、 小区选择 /重选信息等。 这些消息都是便于用户了解 小区的配置情况, 确定终端是否可以驻留以及是否可以发起正常呼叫。
当用户设备开机后第一次选定合适的小区时, 它从广播信道 (Broadcast
Channel , BCH)上读取该小区的所有***信息; ***信息可以分为主信息块 (Master information block, MIB)、 调度块 (Scheduling Block, SB)和***信息块 (SIB) , MIB提供 SIB的参考和调度消息, 并且提供一个或者两个 SB的参考和 调度消息, SB也提供 SIB的参考和调度信息, 而每个 SIB的调度信息只能包 含在 MIB或者 SB中, 当 MIB中调度信息放不下的时候, SB可以作为补充, 继续放调度信息。
该***规定以固定周期在 BCH上广播一个***信息, ***信息的长度必 须与一个 BCH传输块的大小相匹配, 为此, 需要将有些***信息块进行分割 或者級联; 例: : 主公共控制物理信道 (Primary Common Control Physical Channel, P-CCPCH)规定, 固定周期为 20ms, 固定传输块大小为 246bits , 为 了满足该信道的传输需求, 必须对有些 SIB进行分割和 /或者級联处理。
比如: 如果 SIB大小大于 BCH传输块大小, SIB将被分割, 并在多个传 输块中进行传输。 如果 SIB大小小于 BCH传输块大小, 则将几个 SIB、 第一 个分割块、 或者最后一个分割块級联后放入同一个传输块中。 为了能够正确 的识别一个传输块中包含的多个 SIB或者分割块, 不同类型的 SIB或者分割 块都会包含头部域和数据域两部分, 这里包含头部域与和数据域的分割块称 之为***信息子块。
***信息块在广播信道传输时, 有两种存在形式, 一种是完整的***信 息块 (Complete SIB), 另一种是被分割的***信息块。
对某个***信息块分割处理之后, 分割块可以分为第一个分割块 (Fisirt segment )、 中间分割块 ( Subsequent segment ) 和最后一个分割块 ( Last Segment) , 下面对这三种分割块的数据格式进行解释说明。
Fkst segment包括: SIB type、 SEG—COUNT和 SIB data; 其中, SIB type , SEG_COUNT为头部域 (header field); SIB type代表该分割块中的 SIB data 所对应的 SIB类型; SEG_COUNT代表该 SIB所分割的总块数; SIB data代表 该 SIB分割后的第一段数据。
Subsequent segment包括: SIB type、 Segment index和 SIB data; 其中, 其 中 SIB type , Segment inde 为 header field; SIB type的意义同上 , Segment index 代表此分割块的编号, 即, 该分割块是第几个分割块, SIB data里存放的是此 SIB分割后的第 Segment index段数据。
Last segment包括: SIB type、 Segment inde 和 SIB data; Last段内容基本 上同 Subsequent段, SIB data里存放的是此 SIB分割后的最后一段数据。
下面介绍一下 Complete SIB , Complete SIB包括: SIB type和 SIB data; 其中, SIB type为 header field , SIB type的意义同上, SIB data意义也同上, 只 不过里面存放的是整个 SIB的数据。
现有的 BCH传输协议中规定了 SIB type 占用比特为 5bits ; SEG_CONT 和 Segment index各占用比特为 4bits , 这些信息称之为头信息, 由于这些头信 息会占用传输块的部分比特位, 导致一个传输块中的包含的有效数据减少, 数据传输效率低。 尤其是, 当***信息块被分割成多个传输块时, 每个传输 块中都要包含部分头信息, 致使数据传输效率低的问题更为明显。 因此, 这 些头信息可以看成传输块中数据的冗余信息, 这些信息越多, 用户的接入延 时越长, 用户体验会越差。
为了减小用户的接入延时, 提升用户体验, 本步驟需要从***中所有的 ***信息块中, 选择一部分***信息块作为待处理***信息块, 后续将对所 选择的这些***信息块进行处理, 使得这些***信息块的头信息实际占用比 特数减少, 从而提升用户的体验。
步驟 103, 所述基站设置***信息子块的格式, 包括: 当所述***信息子 块为第一个分割块时, 设置该***信息子块中的头部域包含: ***信息块的 类型映射的第一类型号和***信息块的总分割块数; 当所述***信息子块为 非第一个分割块时, 设置该***信息子块中的头部域包含: ***信息块的类 型映射的第一类型号和分割块编号; 当所述***信息子块为完整的***信息 块时, 设置***信息子块中的头部域包含: ***信息块的类型映射的第一类 型号; 其中, 所述第一类型号占用的比特数小于***信息块的类型占用的比 特数。
将所述待处理***信息块的***信息块类型 (SIB type) 映射为第一类型 号, 并在调度信息中包含所述 SIB type与第一类型号之间的映射关系, 所述 第一类型号占用比特数小于 5比特;
仍旧以 WCDMA***总共有 18种类型的***信息块 (System Information
Block, SIB) , 分别标识为 SIB1〜SIB18为例, 对该步驟进行解释说明。
SIB1〜SIB18这 18种类型的 SIB的标准类型号依次为 1〜 18,每一个 SIB type 都用 5bits 来标识, 例如: "00000" 标识 "1"、 "00001" 标识 "2"、 "00010" 标识 "3" , 以此类推; 所述 SIB type包含在***子信息块的 header field中, 为了减小某些类型的 SIB的头信息中 SIB type所占比特, 需要对这些 SIB的 SIB type进行映射处理, 使得映射处理后的第一类型号占用比特小于 SIB type 占用比特。 即, 映射处理后的第一类型号小于 5bits。
例如: 当步驟 101选择出 SIB1〜SIB4这四种类型的 SIB 作为待处理 SIB , 则本步驟, 将 SIB1〜SIB4这四种类型的 SIB中的 SIB type分别映射为 2bits的 第一类型号; 可以映射为 SIB1 的标准类型号 "00000" 映射为第一类型号为 "00", SIB2的标准类型号 "00001" 映射为第一类型号为 "01", SIB3的标准 类型号 "00010" 映射为第一类型号为 "10" , SIB4的标准类型号 "00011" 映 射为第一类型号为 "11", 映射完成之后,将 SIB1〜SIB4这四种类型的 SIB type 与第一类型号之间的映射包含在需要发送给用户设备的调度信息中, 以使得 用户根据该包含映射关系的调度信息接收基站发送的***信息块。
下面对调度信息进行解释说明。
在广播信道中传输的 MIB或者 SB 中包含各 SIB的调度信息, 所述调度 信息主要包括: 重复周期 SIB_REP、 分段总数 SEG_COUNT、 初始位置 SIB_POS (第一段的位置) 和位置偏移 SIB—OFF等信息; 其中, SIB_REP表 示***信息块 SIB的重复周期, 例如: 重复周期是 4, 则表示每 4帧发送一次 该 SIB , 所述帧为 10ms无线帧; 各***信息块、 主***信息块或调度块都应 给出其对应的 SIB_REP , 通常定义为 SIB_REP越小其优先級越高。
对一个分段的 SIB 来说, 因为知道了第一段的位置 SIB_POS 和偏移 SIB—OFF,则其余段的位置可以由公式 SIB_POS(i) = SIB_POS(i-l) + SIB_OFF(i) 推出, 这是一个递推的形式, 其中 i = 1, 2, · · · SEG_COUNT-l , SIB_OFF(i) 的含义就是第 i个 Subsequent segment相对于第 i-1个的偏移值。 该 SIB共有 SEG_COUNT-l个 SIB—OFF , 每一个 SIB—OFF (i)数值有可能不相同。
步驟 103,所述基站在广播信道上发送所述传输块和***信息子块的调度 信息, 所述调度信息中包含所述***信息块的类型与第一类型号之间的映射 关系。 在广播信道上周期性发送***信息块, 需要按照广播信道的传输块大小 需求, 对***信息块进行分割和 /或者級联处理得到多个传输块, 在每个传输 块中可能包含一个或者多个***信息子块。 按照上述步驟 103操作处理后的 ***信息子块有以下几种形式:
当所述***信息子块为第一分割块时, 所述头部域中包含***信息子块 对应的第一类型号和该***信息的总的分割块数;
当所述***信息子块为非第一分割块时, 所述头部域中包含***信息子 块对应的第一类型号和分割块的编号;
当所述***信息子块为完整的***信息块时, 所述头部域中包含***信 息子块对应的第一类型号;
由于处理后的***信息子块包含第一类型号, 而不包含 SIB type , 减小了 头信息占用的比特数, 减小冗余信息。 由于 UE只按照 SIB type识别 SIB , 因 此, 还需要在调度信息中给出上述 SIB type与第一类别号之间的映射关系, 以便 UE才艮据该映射关系识别对应的 SIB。
UE在 BCH上接收***信息块, 才艮据上述调度信息的针对各个***信息 子块的调度指示, 在指定时刻接收对应的***信息子块, 按照顺序读取每一 个分割块并进行解析操作。
通过上述本发明实施例可以看出: 将***中某些 SIB的 header field中包 含第一类型号, 且该第一类型号占用比特小于 SIB type的占用比特, 减小了 这些***的 SIB在广播信道中的冗余信息, 提高广播信道传输***信息的速 率, 以提高用户体验。 针对上述本发明实施例 1步驟 101 :按照预设条件选择至少一种类型的系 统信息块作为待处理***信息块, 本发明实施例还提供了多种实现方式, 下 面依次对这些实现方式进行解释说明。
在第一种实现方式中, 所述按照预设条件选择至少一种类型的***信息 块作为待处理***信息块, 可包括:
判断每种类型的***信息块的分割块数是否大于第一阈值;
如果是, 则将该类型的***信息块作为所述待处理***信息块。
例如: 预设的第一阈值为 10 , ***中共有 18种类型的 SIB ; 由于每种类 型 SIB的大小是不同的, 因此, 其分割块数也不相同, 若***中 18个 SIB , 只有 SIB5、 SIB11和 SIB18的分割块数大于 10, 其余的 SIB的分割数均小于 或者等于 10 , 则选择 SIB5、 SIB 11和 SIB18这三个 SIB作为待处理***信息 块, 在实际的传输中***信息子块的 header field中包含第一类型块; 而其余 的 SIB1〜SIB4、 SIB6〜SIB10、 和 SIB12〜SIB17这十五种类型的***信息块不做 后续的处理,仍旧采用现有的传输方式,即,仍旧在***信息子块的 header field 包含 SIB type0
在第二种实现方式中, 所述按照预设条件选择至少一种类型的***信息 块作为待处理***信息块, 可包括:
判断每种类型的***信息块的版本号是否与预设版本号相符;
如果是, 则将该类型的***信息块作为所述待处理***信息块。
例如: 随着通信技术的发展, 3G通信***已经发展到 R12版本, 在某些 版本中可能有的新的***信息类型引入。 所述预设版本号可以是某一个或者 多个指定版本号 (连续的版本号或者离散的版本号), 也可以是哪一个版本之 后的所有版本号。 比如: 当预设的版本号为 R12时, 则将 R12所引入的*** 信息块作为待处理***信息块, 而其他版本中引入的 SIB仍然现有流程进行 处理。
在第三种实现方式中, 所述按照预设条件选择至少一种类型的***信息 块作为待处理***信息块, 可包括:
判断承载***信息块的广播信道是否为指定信道, 所述指定信道为主公 共控制物理信道或辅助公共控制物理信道; 如果是, 则将该类型的***信息块作为所述待处理***信息块。
当***同时采用主公共控制物理信道或辅助公共控制物理信道这两种广 播信道, 才能够利用上述第三种实现方式执行选择操作。
例如: 当***同时采用主公共控制物理信道或辅助公共控制物理信道这 两种广播信道时, 指定信道为辅助公共控制物理信道, 则将要在辅助公共控 制物理信道发送的 SIB,作为待处理***信息块, 则仅对某一种广播信道上传 送的 SIB进行处理, 而在另外一种广播信道上传输的 SIB仍旧采用现有流程 进行处理。
在第四种实现方式中, 所述按照预设条件选择至少一种类型的***信息 块作为待处理***信息块, 可包括:
判断每种类型的***信息块的类型号实际所占比特数是否小于 SIB type 所占比特数;
如果是, 则将该类型的***信息块作为所述待处理***信息块。
例如: SIB1〜SIB4的 SIB type依次为 1〜4, 这些 SIB实际采用 2bits即可 表示, 小于 SIB type所占比特 5bits; SIB5〜SIB8的 SIB type依次为 5〜8, 这些 SIB实际占用比特均为 3bits小于 SIB type所占比特 5bits ; SIB9〜SIB16的 SIB type依次为 9〜16 , 这些 SIB实际占用比特均为 4bits小于 SIB type所占比特 5bits , 所以可以选择 SIB1〜SIB16这 16种类型的 SIB作为待处理的***信息 块。
在第五种实现方式中, 所述按照预设条件选择至少一种类型的***信息 块作为待处理***信息块, 可包括:
判断每种类型的***信息块的大小是否不大于广播信道的传输块大小; 如果是, 则将该类型的***信息块作为所述待处理***信息块。
例如: 判断***信息块大小与广播信道的传输块大小之间的大小关系是 为了判断***信息块是否需要被分割。 当 SIB 大小大于广播信道的传输块大 小时, 则该 SIB 需要被分割, 当 SIB 大小等于广播信道的传输块大小时, 该 SIB满足广播信道的传输块需求,则该 SIB不需要再分割可直接在广播信道上 发送; 或者, 当该 SIB 大小小于广播信道的传输块大小时, 则该 SIB 需要与 其他类型 SIB , 或者与其他类型 SIB分割块級联后, 才能在广播信道上发送。 本实现方式中将那些不需要分割的***信息块作为待处理***信息块。 为了进一步的减小***信息块在广播信道中的冗余信息, 本发明实施例 还提供了优选方案, 该优选方案是在上述实施例 1 方法的基础上, 当所述待 处理***信息块被分割成至少两个分割块时, 进一步改变这些***信息块的 ***信息子块的 header field , 以减小其中的冗余量。 下面以方法实施例 2为 例, 对该优选方案进行解释说明。
参阅图 2,示出的本发明实施例的一种***信息传输方法的实施例 2的流 程图, 所述方法可包括:
步驟 201:基站按照预设条件选择至少一种类型的***信息块作为待处理 ***信息块;
步驟 202 : 所述基站才艮据广播信道的传输需求,对所述待处理***信息块 进行分割和 /或級联处理得到传输块,所述传输块中包含至少一种类型的*** 信息子块, 所述***信息子块包括: 头部域和数据域;
步驟 201〜202与上述实施例中步驟 101〜102相同, 在此不再赘述。
步驟 203, 所述基站设置***信息子块的格式, 包括: 当所述***信息子 块为第一个分割块时, 设置所述头部域中包含***信息子块对应的第一类型 号和首块标识, 其中, 所述首块标识所占位数小于 4 比特; 当所述***信息 子块为最后一个分割块时, 设置所述头部域中包含***信息子块对应的第一 类型号和末块标识, 其中, 所述末块标识所占位数小于 4比特;
或者, 设置所述***信息子块的头部域中包含所述***信息块对应的第 一类型号和校验位, 其中, 所述校验位所占位数小于 4比特。
在步驟 203中将第一个分割块的 header field中包含首块标识, 而不包含 分割的总块, 以及将最后一个分割块的 header field中包含末块标识, 而不包 含分割块编号, 所述首块标识与所述末块标识不同, 且所述首块标识与所述 末块标识所占比特均小于原有编号所占比特。 如果所述待处理***信息块被分割成至少三个分割块, 为了减小中间分 割块中的冗余信息, 可选的, 所述方法还包括: 所述基站设置所述***信息子块的头部域中包含所述***信息子块对应 的第一类型号和中间块标识, 其中, 所述中间块标识所占位数小于 4比特。
可选地, 中间分割块的标识可以和首块标识或者末块标识相同。
进一步地, 如果所述待处理的***信息块需要分割, 分割后所得到的所 述***信息子块的头部域中包含所述***信息块对应的第一类型号和校验 位, 其中, 所述校验位所占位数小于 4 比特。 例如: 设置分割块编号为奇数 的分割块的校验位为 1, 设置分割块编号为偶数的分割块的校验位为 0。 则在 第一个分割块的 header field 中包含第一类型号和 1, 第二个分割块的 header field中包含第一类型号和 0, 依次类推。 其中, header field中包含校验位也可 以适用于第一个分割块和最后一个分割块。
进一步地, 如果所述待处理的***信息块需要分割, 分割后所得为中间 块的***信息子块的 header field中包含所述***信息块对应的第一类型号和 奇偶校验位, 其中, 所述奇偶校验位所占位数小于 4 比特; 分割后为第一个 分割块的***信息子块的 header field中包含所述***信息子块对应的第一类 型号和首块标识。
可选地, 分割后为最后一个分割块的***信息子块的 header field中包含 所述***信息子块对应的第一类型号和末块标识。
例如: 设置首块标识 "00" 标识第一个分割块, 末块标识 "11 " 标识最 后一个分割块, 设置 "01 " 标识中间分割块的偶数块, 设置 "10" 标识中间 分割块的奇数块; 则所述第一块标识、 最后一块标识以及中间分割块标识占 用比特均为 2bits , 均小于 4bits。 再举个例子, 设置首块标识 "0" 标识第一个 分割块, 设置中间分割块的标识 "0" 标识中间分割块, 即, 中间分割块的表 示与首块标识相同, "1 " 标识最后一个分割块。 则所述首块标识、 中间分割 块的标识以及末块标识占用比特均为 1 bits , 均小于 4bits。
步驟 204,所述基站在广播信道上发送所述传输块和***信息块的调度信 息, 所述调度信息中包含所述***信息块的类型与第一类型号之间的映射关 系。
通过上述本发明实施例可以看出: 在将***中某些 SIB的 SIB type映射 成第一类型号的基础上, 还对这些 SIB 中经过分割处理的 SIB的分割块格式 进行了设置, 减小了分割块中的冗余信息量, 能够提高用户体验。 为了进一步减小广播信道传输***信息的冗余信息, 本发明实施例还提 供了另一种***信息传输方法, 下面结合图 3对该方法进行解释说明。
参阅图 3, 示出的本发明实施例***信息传输方法的实施例 3的流程图, 该方法可包括:
步驟 301, 基站根据广播信道的传输需求, 对***信息块进行分割和 /或 級联处理得到传输块, 所述传输块中包含由数据域组成的***信息子块; 在实际的应用中, ***信息块的大小与广播信道的传输块大小可能不同, 为了保证***信息块在广播信道上正常发送, ***信息块的长度必须与 P-CCPCH 传输块的大小相匹配, 则需要对***信息块进行分割和 /或級联。 例如: 广播信道 P-CCPCH的传输要求是: 固定的传输间隔 20ms、 固定的传 输块 246bits, 当***信息块需要在 P-CCPCH上广播时, ***信息块的长度必 须与 P-CCPCH传输块的大小相匹配, 因此, 必须按照 P-CCPCH的传输要求 对***信息块进行分割和 /或者級联处理, 此时处理后的包含在传输块中的称 之为***信息子块, 如果进行級联的操作, 一个传输块中可能包含多于一个 的***信息子块。
现有的***信息子块的格式有以下四种: complete包含: SIB type和 data; First segment包含: SIB type、 SEG—COUNT和 SIB data; Subsequent segment 包含: SIB type、 Segment inde 和 SIB data; Last segment包含: SIB type、 Segment index和 SIB data其中, SIB type、 SEG—COUNT、 Segment index包含在 header field 中被称之为头信息。
在本步驟中, ***信息子块仅包含 SIB data , 不包含 header field。
步驟 302, 所述基站在广播信道上发送***信息块的调度信息, 所述调度 信息中包含所述广播信道的传输块所包含的***信息子块的指示信息;
步驟 302, 所述基站在广播信道上发送所述传输块。
经过步驟 301 对传输块中***信息子块的处理, 使得***信息子块中不 再包含 header field , 传输的数据量最大化, 同时, 发送给 UE的调度信息中还 会指示每个***信息子块的传输时刻, 使得 UE得知在什么时刻接收哪一个 ***信息块的哪一个***信息子块。
通过上述实施例可以看出, 在广播信道上传输***信息块时, 通过减少 header field 的大小, 使得传输块携带有效数据最大化, 以减小***信息块在 发送时的冗余信息, 从而能够提高用户体验。 在上述实施例 3 的基础上, 进一步, 本发明实施例还提供了一种优选方 案, 该优选方案对上述不包含 header field的传输块进行加掩处理, 以使 UE 在接收传输块时进行校验处理, 保证 UE接收***信息子块的可靠性。
可选的, 在所述基站在广播信道上发送所述传输块之前, 所述方法还包 括:
所述基站利用所述传输块的指示信息对所述传输块进行加掩处理。
例如: 当传输块中的***信息子块为 complete时, 利用该***信息子块 的指示信息 SIB type (或者 SIB type和分割块数) 对传输块进行加掩处理; 当 传输块中的***信息子块为 Fkst segment时, 利用该***信息子块的指示信 息 SIB type和 SEG_COUNT对传输块进行加掩处理; 当传输块中的***信息 子块为 Subsequent segment时, 利用该***信息子块的指示信息 SIB type和 Segment index 对传输块进行加掩处理; 当传输块中的***信息子块为 Last segment时,利用该***信息子块的指示信息 SIB type和 Segment index对传输 块进行加掩处理。
如果一个传输块中包含至少两种类型的***信息子块, 可选的, 所述利 用所述***信息子块的指示信息对所述传输块进行加掩处理, 包括:
选择任一种类型的***信息子块的指示信息, 对所述传输块进行加掩。 例如: 可以选择任一种***信息子块的 SIB type对传输块进行加掩, 或 者, 选择任一种***信息子块的类型和总分割块数对传输块进行加掩, 或者, 选择***信息块的类型和分割块编号对传输块进行加掩。
优选的, 如果一个传输块中包含至少两种类型的***信息子块, 可以选 择 SIB type号最小的 SIB 的指示信息对传输块进行加掩。
可选地, 所述通过指示信息对传输块进行加掩是指通过所述指示信息对 在空口传输的数据包在物理层进行加掩处理; 或者通过所述指示信息对在空 口传输的数据包在媒体接入控制层进行加掩处理。
终端根据调度信息中指示的传输块中***信息子块的发送时刻, 依次接 收每一个传输块, 并根据所述指示信息对所接收的传输块进行解掩, 确定所 接收的传输块是否正确。 如果解掩成功, 则表明接收的传输块正确; 否则, 表明接收的传输块有误, 此时, 终端可以直接丟弃此传输块。 这样处理, 避 免终端直到接收完所有的传输块才进行判断,提高终端接收传输块的可靠性, 间接地提高用户体验。
可选地, 在上述本发明的实施例中, 网络侧可以针对部分***信息块执 行上述操作, 所述的部分***信息块可以才艮据实施例 1 中的方式进行***信 息块的选择。
通过上述本发明实施例可以看出, 在广播信道上传输***信息块时, 通 过减小 header field , 使得传输块携带有效数据最大化, 以减小***信息块在 发送时的冗余信息, 从而能够提高用户体验; 进一步利用传输块中包含的系 统信息子块的指示信息对传输块进行加掩处理, 能够提高终端接收传输块的 可靠性。 为了进一步减小广播信道传输***信息的冗余信息, 本发明实施例还提 供了另一种***信息传输方法, 下面结合图 4对该方法进行解释说明。
参阅图 4, 示出的本发明实施例***信息传输方法的实施例 4的流程图, 该方法可包括:
步驟 401, 基站按照广播信道的传输要求, 对***信息块进行分割和 /級 联处理得到传输块, 所述传输块中包含至少一种类型的***信息子块, 所述 ***信息子块包括: 头部域和数据域。
步驟 402, 所述基站设置***信息子块的格式, 包括: 当所述***信息子 块为第一个分割块时, 设置所述头部域中包含***信息子块对应的类型和首 块标识, 其中, 所述首块标识所占位数小于 4 比特; 当所述***信息子块为 最后一个分割块时, 设置所述头部域中包含***信息子块对应的类型和末块 标识, 其中, 所述末块标识所占位数小于 4比特;
或者, 设置所述***信息子块的头部域中包含所述***信息块对应的第 一类型号和校验位, 其中, 所述校验位所占位数小于 4比特;
当***信息块大小大于广播信道的传输块大小时, 需要将该***信息块 分割为至少两个分割块。 比如: 当***信息块被分割之后需要在三个传输块 进行传输时, 对应的***信息子块有三种类型的格式, Fkst segments Subsequent segment和 Last segment 0 其中 , First segment是指该***信息块的 第一个分割块, Last segment是指该***信息块的最后一个分割块。
当所述***信息子块为 First segment时, 所述 header field中包含***信 息子块对应的 SIB type和首块标识;
当所述***信息子块为 Last segment时,所述 header field中包含***信息 子块对应的 SIB type和末块标识。
其中所述首块标识和模块标识小于 4bits。
本步 处理后的 First segment包括: SIB type、 首块标识 (first indicator) 和 data; Last segment包括: SIB type、 末块标识 (last indicator) 和 data; 由 于首块标识和末块标识占用比特均小于 4bits , 因此, 可以节约一定的信道容 量。
步驟 403,所述基站在广播信道上发送所述传输块和***信息块的调度信 息。
可选地, 在所述调度信息中还可能包含所述***信息块采用首块标识和 末块标识的指示。
可选的, 如果所述待处理***信息块被分割成至少三个分割块, 则所述 方法还包括:
如果所述***信息子块为 Subsequent segment, 所述 header field中包含系 统信息子块对应的 SIB type和中间块标识。
可选地, 所述中间块标识可以和首块标识或者末块标识相同。
进一步地, 所述***信息子块的 header field中包含校验位, 且所述校验 位所占比特小于 4比特。
例如: 所述***信息子块的 header field中包含奇偶校验位, 用于接收端 校验所接收到的***信息子块的编号为奇数还是偶数。 如果 " 代表是编号 为奇数的分割块, "0"代表编号是偶数的分割块。则 fkst segment的 header field 中包含 SIB type和奇数块指示位 (设置为 1 ) , 包含第二个分割块的***信息 子块的 header field中包含 SIB type和偶数块指示位 (设置为 0) , 依次类推。
通过上述本发明实施例可以看出: 减小***信息块分割得到的***信息 子块的 header field , 能够减小***信息块在发送时的冗余信息, 从而能够提 高用户体验。 与上述基站侧***信息传输方法实施例 1 相对应的, 本发明实施例还提 供了终端侧的***信息传输方法, 所述方法包括: 步驟 501〜步驟 503,
步驟 501, 终端接收基站发送的***信息块的调度信息, 所述调度信息中 包含***信息块的类型和第一类型号之间的映射关系; 所述第一类型号占用 比特数小于所述***信息块类型的占用比特数;
步驟 502, 终端接收广播信道的传输块, 所述传输块中包含由头部域和数 据域组成的***信息子块, 当所述***信息子块为第一个分割块时, 所述头 部域中包含***信息子块对应的第一类型号和该***信息块的总的分割块 数; 当所述***信息子块为非第一个分割块时, 所述头部域中包含***信息 子块对应的第一类型号和分割块的编号; 当所述***信息子块为完整的*** 信息块时, 所述头部域中包含***信息子块对应的第一类型号;
步驟 503,所述终端才艮据所述调度信息和所接收到的***信息子块头部域 中所包含的信息解析得到***信息块。
通过上述实施例可以看出: 将***中某些 SIB header field中包含第一类 型号, 且该第一类型号占用比特小于 SIB type的占用比特, 减小了这些*** 的 SIB在广播信道中的冗余信息, 提高广播信道传输***信息的速率, 以提 高用户体验。 与上述基站侧***信息传输方法实施例 2相对应的, 本发明实施例还提 供了终端侧的***信息传输方法, 所述方法包括: 步驟 601〜步驟 603,
