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 1为本发明通信模式转换方法实施例一的流程图;
图 2为本发明通信模式转换方法的实施例二的流程示意图;
图 3为本发明通信模式转换装置实施例一的结构示意图。
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。
本文中描述的技术可用于各种通信系统, 例如当前 2G, 3G通信系统和 下一代通信系统, 例如全球移动通信系统( GSM, Global System for Mobile communications ), 码分多址 ( CDMA, Code Division Multiple Access )系统, 时分多址 (TDMA, Time Division Multiple Access ) 系统, 宽带码分多址 ( WCDMA, Wideband Code Division Multiple Access Wireless ), 频分多址 ( FDMA, Frequency Division Multiple Addressing ) 系统, 正交频分多址 ( OFDMA, Orthogonal Frequency-Division Multiple Access ) 系统, 单载波 FDMA ( SC-FDMA )系统, 通用分组无线业务( GPRS , General Packet Radio Service ) 系统, 长期演进(LTE, Long Term Evolution ) 系统, 以及其他此 类通信系统。本发明提供的通信模式转换方法以及装置可用于作为发送端的 用户、 网元节点设备、 基站上。
图 1为本发明通信模式转换方法实施例一的流程图, 如图 1所示, 该方 法包括如下步骤:
步骤 100, 根据预设的信道质量条件, 获取至少一个待转换通信模式, 待转换通信模式满足信道质量条件。
可选的 ,预设的信道质量条件用于保证传输所需信道质量的最低要求或 者满足最基本传输的通信模式复杂度, 例如, 对于一个待转换通信模式, 可 以将满足最低调制与编码策略(Modulation and Coding Scheme, 简称: MCS ) 对应的信号与干扰力 p噪声比值 ( Signal to Interference plus Noise Ratio, 简称: SINR )作为最低要求, 当 SINR低于预设阔值时, 则认为该通信模式为待转 换通信模式, 其中, 该待转换通信模式无法进行信号传输。 而对于满足最基 本传输的通信模式复杂度的情况, 例如在没有开通漫游或者信道条件较差的 地方, 此时, 对于紧急通信不需要进行鉴权、 计费等处理而进行传输, 即为 最基本传输。 当预设的信道质量条件不能保证最基本传输时, 则为不能满足 最基本传输的通信模式复杂度。
对于某一特定频段, 所有的通信模式为集合 A, 集合 A中可以包括: 全 双工、 时分双工( Time Division Duplex, 简称: TDD )、频分双工( Frequency Division Duplex, 简称: FDD ) , 以及其他可能的通信模式。 通信模式转换 装置根据预设的信道质量条件,从集合 Α中确定至少一个通信模式为待转换 通信模式, 待转换通信模式满足信道质量条件, 即通信模式转换装置确定至 少一个满足传输所需信道质量的最低要求或者满足最基本传输的通信模式 复杂度的通信模式为待转换通信模式。通信模式转换装置获得包含所有待转 换通信模式的集合 B。
步骤 101 , 根据切换准则, 分别对至少一个待转换通信模式进行评估, 获取每个待转换通信模式对应的评估值。
具体的,通信模式转换装置根据切换准则,对集合 B中的每一个待转换 通信模式进行评估, 获取每个待转换通信模式对应的评估值。 并且, 切换准 则才艮据不同的系统需求或者用户需求、 信道条件确定, 此处不予限定。
步骤 102, 将至少一个待转换通信模式对应的评估值按照从大到小的顺 序或者按照从小到大的顺序进行排列, 并将通信系统从当前通信模式切换到 排序为 1所对应的待转换通信模式。
具体的, 例如, 集合 B中包括: 全双工、 TDD、 FDD。 其中通信模式转 换装置根据切换准则得到全双工对应的评估值为 5, TDD对应的评估值为 6, FDD对应的评估值为 7 , 若此时以考虑系统的能耗需求的情况为主时, 可以 按照从大到小的顺序进行排列, 则此时排序为 1的对应的待转换通信模式为 FDD, 那么通信模式转换装置将系统切换到 FDD进行信号传输。
本实施例提供的通信模式转换方法,通过通信模式转换装置根据预设的 信道质量条件, 获取至少一个待转换通信模式, 待转换通信模式满足信道质 量条件, 再由通信模式转换装置根据切换准则, 分别对至少一个待转换通信 模式进行评估, 获取每个待转换通信模式对应的评估值, 通信模式转换装置 将至少一个待转换通信模式对应的评估值按照从大到小的顺序或者按照从 小到大的顺序进行排列, 并将通信系统从当前通信模式切换到排序为 1所对 应的待转换通信模式,保证了每一次的对通信系统进行切换时都符合通信系 统和 /或用户的实际需求, 提高了资源利用率并且降低了通信系统切换次数。
图 2为本发明通信模式转换方法的实施例二的流程示意图, 在上述图 1 所示实施例的基础上, 如图 2所示, 步骤 101的一种具体实现方式为:
步骤 101a、 釆用公式(1 ) :
N
^ ( 1 ) 分别对至少一个待转换通信模式进行评估,计算获取每个待转换通信模 式对应的评估值。
其中, 为第 1待转换通信模式的评估值, 是第 1通信模式下第 j个 代价参量的加权值, 是第 i通信模式下的第 j代价参量值, 并且 i、 j、 N 为整数。
具体的, 第 i通信模式下的第 j代价参量值 根据切换准则的不同, 可 以进行相应的设置。 第 i通信模式下第 j个代价参量的加权值1 ^则根据对应 的 对于系统的影响程度进行相应设置, 例如, 若该 与第 i通信模式下的 第 j+1代价参量值 +1相比而言, 对系统影响更大, 则将对应加权值1 ^调 整为与 +1对应的 +1比较而言的较大值。但是具体调整依据具体系统的需求 而定, 此处不予限定。
在通信系统进行通信模式切换时, 可以从不同的需求角度来确定公式 ( 1 ) 中的价参量值以及价参量的加权值, 下面以具体实施例对本发明提供 切换准则进行说明。
在本发明通信模式转换方法的实施例三中, 在上述实施例二的基础上, 优选的, 在以系统的能耗需求的情况作为考虑的主要因素时, 代价参量值可 以包括如下一种或者几种的组合: 切换所需能量值、 射频处理所需能量值、 基带电路消耗能量值、 接收端处理所需能量值和额外消耗能量值。
具体的, 可以为射频处理所需能量值, 在第 i通信模式下, 由于可支 持的编码调制方式、 所分物理资源、 发射功率参量、 发射机的功放系数等参 量会对射频处理所需能量值(该射频处理所需能量值即为发射 /传输信号时所 需的能量值)造成影响。 所以需要通过上述参量确定所以需要射频处理所需 能量值 。 其中, 在实际传输时, 所分物理资源可以为第 i通信模式所需或 者所分到的时频资源 , 例如, 在长期演进网络 ( Long Term Evolution, 简称: LTE ) 中, 可以为物理资源块(Physical Resource Block, 简称: PRB ) 。 由 于射频处理所需能量值(即为发射 /传输信号时所需的能量)对于以考虑系统 的能耗需求为原则的情况是主要的影响因素, 相应的, 由于射频处理所需能 量值^对于在考虑系统的能耗需求的情况时的通信系统的重要性大于切换 所需能量值、 射频处理所需能量值、 基带电路消耗能量值、 接收端处理所需 能量值和额外消耗能量值, 所以射频处理所需能量值^对应的加权值 可 以设置为较大值(其分别大于切换所需能量值对应的加权值、 射频处理所需 能量值对应的加权值、 基带电路消耗能量值对应的加权值、 接收端处理所需 能量值的加权值和额外消耗能量值对应的加权值), 例如设置为 2。
^可以为切换所需能量值, 其代表进行信号传输时当前需要釆用的第 i 通信模式与上一次釆用的通信模式之间切换所需的能量。 若第 1通信模式与 上一次釆用的通信模式一样, 则此时 取零。 若不同, 则根据系统具体情况 计算设定 ¾ , 需要说明的是, 在通信模式进行切换时, 从第 1通信模式转换 到第 1+1通信模式所需的能量与从第 1通信模式切换到第 1-1通信模式所需的 能量可能是相同的, 也可能是不同的, 所以在具体的切换过程中, 需要根据 系统的具体情况设定 。由于切换所需能量值 ^对于在考虑系统的能耗需求 的情况时的通信系统的重要性与射频处理所需能量值^相比要小, 所以, 例 如在射频处理所需能量值^对应的加权值 设置为 2 时, 相应的, 切换所 需能量值 对应的加权值^例如可以设置为 1 , 需要说明的是, 加权值^需 要与其他代价参量的对系统影响的重要性进行比较后进行确定, 其具体的大 小此处不做限定。
^可以为基带电路消耗能量值, 其代表第 i通信模式下编码 /加扰 /调制 等基带电路消耗能量, 根据当前信道情况确定的第 i通信模式下可支持的编 码调制方式, 来进行发送端基带处理消耗的电路能量值, 相应的, 基带电路 消耗能量值 ^对于在考虑系统的能耗需求的情况时的通信系统的重要性与 射频处理所需能量值 ^相比要小,所以,例如在射频处理所需能量值 ^对应 的加权值1^设置为 2时, 相应的基带电路消耗能量值 ^对应的加权值1 ^可 以设置为 1。 ^可以为接收端处理所需能量值, 其代表第 i通信模式下接收端处理接 收到的信号所需的能量, 由于在具体传输过程中, 发送端与接收端的处理能 力已经互相进行了通知, 所以可以对所釆用的编码调制方式下接收端处理接 收到的信号所需的能量进行计算。相应的, 与接收端处理所需能量值 ^对应 的加权值1 ^可以设置为 0.5 ,之所以设置为 0.5 ,是考虑到其为接收端处理所 需能量值, 而对于发送端通信模式的切换影响并不大, 所以为了避免误差, 降低其加权值 W''4。
^可以为额外消耗能量值, 其代表当前待传输的业务釆用第 i通信模式 与其 ^同时传输的业务釆用的不同通信模式不同引起的额外能量消耗。 需要 说明的是, 当通信系统需要为多业务多用户同时进行操作时, 有可能出现一 部分用户 /业务釆用全双工通信模式, 另一部分用户 /业务釆用半双工通信模 式, 为了支持不同的通信模式, 需要考虑额外消耗能量值^。 另外, 对于一 个用户同时发送多个业务时, 也需要考虑额外消耗能量值^。 额外消耗能量 值^与切换所需能量值 类似,只是额外消耗能量值^针对的是不同用户的 通信模式。 需要说明的是, 由于上行信号较少出现一个用户向不同基站同时 传输不同的信号, 所以额外消耗能量值^主要针对为发送端的基站, 当发送 端只向一个接收端只发送一个业务的信号时, 额外消耗能量值^ =0。
或者, 在以系统的负载的情况作为考虑的主要因素时, 代价参量值可以 包括: 功率负载和 /或资源负载。
具体的, 在系统实现中, 为了避免频繁的通信模式切换, 可以考虑各待 转换通信模式的负载情况。 具体的, 为功率负载, 其代表该待转换通信模 式所需的功率。 ^为资源负载, 其代表该待转换通信模式传输具体业务所需 要的资源。
又或者, 为了更加准确的进行通行模式的转换, 提供资源的利用率, 可 以将系统的负载的情况和系统的能耗需求的情况均作为考虑的主要因素, 则 代价参量值包括第一代价参量值和第二代价参量值, 其中, 第一代价参量值 包括如下一种或者几种的组合: 切换所需能量值、 射频处理所需能量值、 基 带电路消耗能量值、 接收端处理所需能量值和额外消耗能量值; 第二代价参 量值包括功率负载和 /或资源负载。
具体的, 例如, 在考虑射频处理所需能量值 、 切换所需能量值^、 基 带电路消耗能量值^的情况, 同时考虑负载, 则可以设定 ¾为功率负载、 ^ 为资源负载。
对于上述三种情况, 在确定了上述代价参量后, 将每一待通信模式的各 代价参量带入公式(1 )中得到相应的评估值 ^。 显然评估值 越大, 对应待 通信模式被釆用的可能性越小, 所以在计算得到每一个待通信模式对应的评 估值 后, 步骤 102的具体实现方式为: 将至少一个待转换通信模式对应的 评估值 按照从小到大的顺序进行排列, 并将通信系统从当前通信模式切换 到排序为 1所对应的待转换通信模式。
在本发明通信模式转换方法的实施例四中, 在上述实施例二的基础上, 优选的, 在以系统的频谱效率的情况作为考虑的主要因素时, 代价参量值包 括如下: 频谱效率和 /或系统实现复杂度。
具体的, 可以为频谱效率, 其代表第 i通信模式的频谱效率。 但是当 传输数据例如为语音数据时, 由于数据量小, 即使釆用最低 MCS, 也只需 要分配很少的资源, 对于这种情况, 各通信模式的频谱效率基本一致, 此时 就需要以系统实现复杂度的情况作为考虑的主要因素,则 M 为系统实现复杂 度值, 其代表第 i通信模式本身实现的复杂度以及从上次通信模式转换到第
1通信模式的转换复杂度, 需要说明的是, 第 1通信模式与相对于该第 1通信 模式的前一个通信模式相同时, 系统实现复杂度值^为 0。 增加系统实现复 杂度值 ^这一代价参量, 可以在进行通信模式切换的过程中, 在其他代价参 量相同的条件下, 将通信系统切换到实现简单的通信模式中, 提高通信系统 的效率, 降低通信系统的使用成本。
更为优选的, 在以系统的最大吞吐量作为考虑的主要因素时, 代价参量 值包括如下: 吞吐量和系统实现复杂度。
具体的, 吞吐量为频谱效率与带宽的乘积, Μ'可以为吞吐量, 其代表单 位时间内成功传输信号的数量, 与考虑系统的频谱效率的情况类似, 当传输 数据例如为语音数据时, 由于数据量小, 既是用最保守的编码调制方式, 也 只需要分配很少的资源, 对于这种情况, 各通信模式的吞吐量基本一致, 此 时就需要再考虑系统实现复杂度, 则^为系统实现复杂度, 该系统实现复杂 度与在考虑系统的频谱效率时的统实现复杂度类似, 此处不再赘述。
进一步的, 为了更加准确的进行通行模式的转换, 提供资源的利用率, 可以将以系统实现复杂度的情况和系统的最大吞吐量共同作为考虑的主要 因素, 则代价参量包括频谱效率、 吞吐量和系统实现复杂度。 具体的, 例如, 为频谱效率、 ^为系统实现复杂度, 若同时考虑最大 吞吐量, 可设置 Μί3为吞吐量。
对于上述三种情况, 在确定了上述第二代价参量值后, 将每一待通信模 式的各代价参量带入公式( 1 ) 中得到相应的评估值 ^。 显然评估值 越小, 对应待通信模式被釆用的可能性越小, 所以在计算得到每一个待通信模式对 应的评估值后, 步骤 102的另一种具体实现方式为: 将至少一个待转换通信 模式对应的评估值 按照从大到小的顺序进行排列, 并将通信系统从当前通 信模式切换到排序为 1所对应的待转换通信模式。
需要说明的是, 在上述实施三和实施例四种, 针对上述四种情况, 均通 过将每一个待转换通信模式对应的多个代价参量带入公式 (1)中得到每一个 待转换通信模式对应的评估值 , 并将至少一个待转换通信模式对应的评估 值 按照从大到小或者从小到大的顺序进行排列, 并将通信系统切换到排序 为 1所对应的待转换通信模式。这样对于每一次切换,均可以从不同的需求, 例如上述四种情况, 对切换进行的评估值 进行计算。 将对于转换通信模式 有影响的因素均包含在切换准则的范围内, 这样保证了每一次的切换都是符 合通信系统和 /或用户的需求,提高了资源利用率并且降低了通信系统切换次 数。
进一步的, 上述实施例分别从系统的能耗需求和 /或负载、 频谱效率和 / 或最大吞吐量确定待转换通信模式。 为了更加准确的进行通行模式的转换, 提供资源的利用率, 显然, 可以将上述不同实施例中的代价参量综合进行考 虑, 在本发明通信模式转换方法的实施例五中, 代价参量值包括第三代价参 量值和第四代价参量值, 第三代价参量值包括如下一种或者几种的组合: 切 换所需能量值、 射频处理所需能量值、 基带电路消耗能量值、 接收端处理所 需能量值、 额外消耗能量值、 功率负载和资源负载。
第四代价参量值包括如下一种或者几种的组合: 频谱效率、 系统实现复 杂度和吞吐量。
具体的, 例如, 从系统的能耗需求角度, 确定待转换通信模式时, 除射 频处理所需能量值 、 切换所需能量值^、基带电路消耗能量值^、接收端 处理所需能量值 Μ4和额外消耗能量值^等代价参量外,可以从最大吞吐量角 度考虑再添加一个第四代价参量值 , 代表吞吐量, 需要说明的是, 对于从 系统的能耗需求出发确定待转换通信模式时,对应待转换通信模式的评估值 越大, 对应待通信模式被釆用的可能性越小。 而对于从最大吞吐量角度出 发确定待转换通信模式时, 评估值 ^越大, 对应待通信模式被釆用的可能性 越大。 因此, 为了统一各待转换通信模式最终排列方式, 可以将添加的吞吐 量对应的加权值^设为负值。并根据上述代价参量以及相应的加权值获得对 应待转换通信模式的评估值, 此时由于代表吞吐量的代价参量对应的加权值 ^设为负值,所以将至少一个待转换通信模式对应的评估值 按照从小到大 的顺序进行排列, 并将通信系统从当前通信模式切换到排序为 1所对应的待 转换通信模式。 当然, 若将射频处理所需能量值 、 切换所需能量值^、 基 带电路消耗能量值 ^、接收端处理所需能量值 M"和额外消耗能量值 ^对应的 加权值设置为负值, 将吞吐量 对应的加权值 设为正值, 此时, 将至少 一个待转换通信模式对应的评估值 按照从大到小的顺序进行排列, 并将通 信系统从当前通信模式切换到排序为 1所对应的待转换通信模式。
又例如, 从频谱效率的角度, 确定待转换通信模式时, 除了频谱效率、 系统实现复杂度的第二代价参量值,还可以从负载角度再添加两个第一代价 参量^、 Μ4 , 其中^可以为功率负载、 Μ4可以为资源负载, 由于, 从频谱 效率的角度,确定待转换通信模式时, 可以将功率负载^与资源负载 ¾对应 的加权值设为负值, 则将至少一个待转换通信模式对应的评估值 按照从大 到小的顺序进行排列, 并将通信系统从当前通信模式切换到排序为 1所对应 的待转换通信模式。
上述加权值正值或负值的设置, 本发明不予限定, 可以根据系统的具体 情况进行设置, 只要保证排序为 1的待转换通信模式为系统发送业务时最佳 的通信模式, 符合系统和 /或用户的实际要求, 满足最优的资源利用率。
