一种资源调度方法、 用户设备、 基站及系统
技术领域
本发明涉及移动通信技术, 尤其涉及一种资源调度方法、 用户设备、 基 站及系统。
背景技术
随着人们对无线通信的要求不断提高, 无线通信技术在速率、 容量、 质 量上都有着迅猛发展。在长期演进(Long Term Evolution, 简称 LTE )系统中, 为了提高数据传输的速率, 要求用户设备(User Equipment, 简称 UE ) 即终 端具备很强的处理能力, 如需要持续的监听物理下行控制信道(Physical Downlink Control Channel,简称 PDCCH ),在下行需要支持 64QAM (Quadrature Amplitude Modulation, 相正交振幅调制)的编码能力等。 为了减少用户设备接 入网络的延时, 增强用户的体验, 协议规定 LTE的终端接入网络的延迟不能 超过 100毫秒。 为了使用户设备能够在不同的系统间自由的切换, 要求用户 设备支持不同的无线接入技术。
然而在实际的应用中, 不是所有的用户设备都需要支持很高的速率或较 少的接入延时。 随着自动化信息釆集需求的飞速发展, 智能终端广泛应用于 无线通信网络, 这部分应用包括自动抄表、 温度控制、 生命检测、 远端诊断 交通监控、 告警系统、 海上救援、 自动售货机、 开车付费等。 在这些应用中, 有些应用需要具备较高的速率传输要求如生命检测, 有些需要具备较少的接 入延时如告警系统, 有些却只需要支持很低的速率传输要求比如自动抄表, 其实际传输速率只需要 10 千比特 /秒。 对于低速率要求的终端, 如果釆用满 足现有协议规定需求的硬件和软件, 其成本就会很高, 这必然造成资源浪费, 也不利于这类终端的广泛应用。

图 1为本发明的资源调度方法的流程图;
图 2为根据本发明实施例一的接入网络的流程图;
图 3为根据本发明实施例二的接入网络的流程图;
图 4为本发明的资源调度系统的示意图。
本发明的较佳实施方式
本发明提供的资源调度方法, 如图 1所示, 主要包括下面步骤:
S10、 基站接收 UE上报的传输能力信息; 以及
S20、 基站根据所述传输能力信息对所述 UE实施资源调度。
这样, 基站通过获取用户设备的传输能力信息, 可以更加精细的分配资 源, 可以提高空口资源的使用效率; 同时由于用户设备处理能力的降低, 可 以显著降低其成本。
为使本发明的目的、 技术方案和优点更加清楚明白, 以下举实施例并参 照附图, 对本发明进一步详细说明。 需要说明的是, 在不冲突的情况下, 本 申请中的实施例及实施例中的特征可以相互组合。
实施例一
在长期演进系统中, 一些实施检测的用户设备需要频繁的向网络侧发送 小数据量的测量报告, 比如每隔 5分钟需要上报一次测量数据, 速率只需要 10千比特 /秒。如果釆用满足现有协议规定需求的硬件和软件, 这些用户设备 的成本会很高, 其能够达到的数据传输速率也将远远超过实际需求, 这不仅 浪费制造成本, 而且不利于网络侧针对这些用户设备釆取高效的资源调度算 法, 造成空口资源的浪费。
针对上述问题, 本实施例提出一种新的用户设备, 该用户设备釆用了较 低速率的处理芯片, 其不能连续的监听 PDCCH上的信令, 只能间隔一个子 帧 (在 LTE系统中, 一个子帧等于 1毫秒, 现有协议规定处于连接状态的用 户设备需要在每个子帧监听 PDCCH上的信令, 以便检出属于自己的 PDCCH 信令)或多个子帧才能继续接收 PDCCH上的信令, 其接入网络的流程如图 2 所示:
步骤 101 , 用户设备在所驻留的小区发起随机接入, 向该小区所属的基 站发送无线资源控制 ( RRC )连接请求( Connection Request )信令。
本实施例中, 用户设备在 RRC连接请求中携带时域处理能力信息, 此处 指针对 PDCCH的处理能力信息, 这需要在 RRC连接请求中新增信元表示时 域处理能力信息。
在本实施例中, 时域处理能力信息是指该用户设备需要间隔一个子帧监 听 PDCCH信令或者间隔多个子帧监听 PDCCH信令, 或者在奇数子帧监听 PDCCH信令, 或者在偶数子帧监听 PDCCH信令, 即指用户设备不能持续的 接收 PDCCH信令。 此处接收 PDCCH信令是指接收 PDCCH上传输的信令。
步骤 102, 基站为用户设备分配资源, 向用户设备发送 RRC连接建立 ( RRC Connection Setup )信令。
本实施例中, 基站获知用户设备的时域处理能力信息后, 需要据此实施 对该用户设备的资源调度, 基站不能持续的调度该用户设备, 需要间隔一个 子帧或间隔多个子帧才能向该用户设备发送一次 PDCCH信令, 或者需要在 奇数子帧或偶数子帧向该用户设备发送一次 PDCCH信令。 基站可以在向该 用户设备发送 PDCCH信令之后, 每隔一个子帧或多个子帧再向该用户设备 发送 PDCCH信令。 例如, 如果用户设备在 RRC连接请求中上报需要间隔 6 个子帧才能监听 PDCCH信令,基站可以周期性的调度该用户设备, 如在第 1 个子帧、 第 7个子帧、 第 13个子帧、 第 19个子帧…调度该用户设备。 如果 在第 7个子帧没有数据发送给用户设备, 则跳过这个子帧, 基站还是依照原 周期实施对用户设备的调度, 即还在第 13个子帧、 第 19个子帧…调度该用 户设备。 这样用户设备可以简化自己检测 PDCCH信令的时机, 同时避免错 过基站对自己的调度。
步骤 103 , 用户设备收到 RRC连接建立后, 向基站发送 RRC连接建立 完成( RRC Connection Setup Complete )信令, 该信令还包含用户设备发送给 核心网的非接入层信令, 例如附着请求或业务请求。
步骤 104, 基站收到 RRC连接建立完成信令后, 向核心网发送初始 UE 信令( Initial UE Message ) , 其中包含非接入层信令, 例如附着请求或业务请 求。
步骤 105,核心网收到初始 UE信令后,对该用户设备进行鉴权和安全建 立, 核心网向基站发送初始上下文建立请求( Initial Context Setup Request ) , 其中包含基站需要为用户设备建立的数据接入承载( Data Radio Bearer, 简称 DRB ) 的服务质量参数和安全配置的参数等。
步骤 106, 基站收到初始上下文建立请求后, 为该用户设备建立 DRB配 置参数, 向该用户设备发送 RRC 连接重配置 ( RRC Connection Reconfiguration )信令。
由于基站在步骤 102中获得了该用户设备针对 PDCCH的处理能力信息, 因此基站不对该用户设备进行持续调度, 而是在上一次向该用户设备发送 PDCCH信令之后, 间隔一个或多个子帧再向该用户设备发送 PDCCH信令。 在 RRC连接重配置中包含为该用户设备配置的资源, RRC信令需要由物理 下行共享信道(Physical Downlink Shared Channel, 简称 PDSCH )传输, 而 PDSCH在频域中的位置和调制方式等由处于同一子帧的 PDCCH指示, 用户 设备需要根据自己的无线网络临时标识( Radio Network Temporary Identifier ) 检测出属于自己的 PDCCH信令,然后根据 PDCCH信令的指示检出同一子帧 中的 PDSCH。
步骤 107,用户设备收到 RRC连接重配置信令后,应用其中的参数配置, 向基站发送 RRC连接重配置完成( RRC Connection Reconfiguration Complete ) 信令。
步骤 108, 基站收到 RRC连接重配置完成后, 向核心网发送初始上下文 建立 p向应 ( Initial Context Setup Response )信令。
至此, 用户设备顺利接入网络, 与基站建立了 DRB , 可以向网络侧发送 数据。
在本实施例中, 用户设备在 RRC连接请求中携带了时域处理能力信息, 以便基站能够据此合理的调度该用户设备, 避免持续的调度该用户设备, 造 成资源的浪费。 由于用户设备不需要具备持续监听 PDCCH信令的能力, 因 此该用户设备可以降低处理器的频率、 降低处理器的存储空间、 降低处理器 的运算速度, 这对降低用户设备的成本是十分有利的。 同时, 用户设备不能 持续监听 PDCCH信令, 也降低了其资源需求, 有助于基站服务更多的用户 设备, 增加了整个系统的容量。
本实施例还有其他的实现方式, 例如, 用户设备没有在步骤 101 中向基 站发送时域处理能力信息,而是在步骤 103中向基站发送时域处理能力信息, 这需要在 RRC连接建立完成信令中增加信元。由于基站推迟获得了不能持续 调度该用户设备的信息,这能导致基站在第一次向该用户设备发送 RRC连接 建立信令时(向该用户设备持续发送了 PDCCH信令) , 该用户设备没有收 到, 由此基站不会收到用户设备反馈的确认信息, 因此基站将再次向用户设 备发送 RRC连接建立信令。 如果基站仍然没有收到该用户设备的确认信息, 还将继续发送。 从上面的过程可以看出, 如果在步骤 103中再向基站发送关 于 PDCCH的处理能力信息, 该用户设备建立 RRC连接的时间将可能变长, 但由于基站釆用的混合自动重传请求(Hybrid Automatic Repeat Request, 简 称 HARQ )技术,基站重复多次后可以成功的向用户设备发送 RRC连接建立 信令。 考虑到此类用户设备所发起的业务是延迟容忍 (Delay Tolerant ) , 或 称为低优先级, 因此推迟建立 RRC连接对这类用户设备来说是可以接受的。
本实施例中, 时域处理能力信息是通过 RRC信令发送的, 事实上也可以 通过媒质接入层控制( Medium Access Control, 简称 MAC )信令向基站发送, 这需要在现有的媒质接入层控制信令中增加信元表示。
本实施例中, 时域处理能力信息是指用户设备需要间隔一个子帧监听 PDCCH信令或者间隔多个子帧监听 PDCCH信令, 时域处理能力信息还可以 是指用户设备不具备持续接收 PDSCH数据的能力; 或者用户设备连续接收 PDSCH数据的最小时间间隔;或者用户设备不具备在 PUCCH( Physical Uplink Control Channel, 物理上行控制信道)持续发送信令的能力; 或者用户设备不 具备在 PUSCH ( Physical Uplink Shared Channel, 物理上行共享信道)持续发 送数据的能力; 基站获得用户设备的时域处理能力信息后, 需要合理的实施 调度,避免资源浪费, 如基站获知用户设备不能持续的接收 PDSCH数据, 需 要间隔着向用户设备发送 PDSCH数据; 如果基站获知用户设备不具备在 PUCCH持续发送信令的能力,则不能为该用户设备持续的分配用于信令传输 的上行授权( UL Grant ); 如果基站获知用户设备不具备在 PUSCH持续发送 数据的能力, 则不能为该用户设备持续的分配用于数据传输的上行授权。
实施例二
在长期演进系统中, 一些用户设备只需要偶尔发送和接收小数据, 因此 不需要具备很强的处理能力, 在本实施例中, 用户设备不具备持续接收
PDCCH信令能力。 其接入网络的流程如图 3所示:
步骤 201 , 用户设备在所驻留的小区发起随机接入, 向该小区所属的基 站发送 RRC连接请求信令。
步骤 202, 基站为用户设备分配资源, 向用户设备发送 RRC连接建立信 令。
步骤 203 , 用户设备收到 RRC连接建立后, 向基站发送 RRC连接建立 完成信令, 该信令还包含用户设备发送给核心网的非接入层信令, 例如, 附 着请求。
步骤 204, 基站收到用户设备的 RRC连接建立完成信令后, 向用户设备 发送 UE能力查询 ( UE Capability Enquiry )信令。
由于基站在步骤 201 发现该用户设备没有上报临时移动站标识 ( Temporary Mobile Station Identifier ) , 因此基站判断该用户设备未注册过, 需要获取该用户设备的能力信息。
步骤 205 ,用户设备收到能力请求信令后,向基站发送的 UE能力信息( UE Capability Information ) , 其中包含了 UE的无线接入能力信息, 包括该用户 设备的接入层版本信息、 射频参数信息 (RF parameters ) 、 以及类型信息 ( ue-Category )等, 为了实现本发明, 用户设备在 UE 能力信息中新增信元 表示该用户设备的时域处理能力信息,即该用户设备不具备持续监听 PDCCH 信令的能力, 为了辅助基站对其的调度, 用户设备上报的时域处理能力信息 还包含持续监听 PDCCH信令的最小时间间隔, 可以用子帧数量表示。
步骤 206, 基站获得该用户设备的能力信息后, 保存这部分能力信息, 以便将其应用于对该用户设备的调度。 基站向核心网发送初始 UE信令, 其 中包含非接入层信令, 例如, 附着请求。
步骤 207,核心网收到初始 UE信令后,对该用户设备进行鉴权和安全建 立, 核心网向基站发送初始上下文建立请求, 其中包含基站需要为用户设备 建立的数据接入承载 DRB的服务质量参数和安全配置的参数等。
步骤 208, 基站收到初始上下文建立请求后, 为该用户设备建立 DRB配 置参数, 向该用户设备发送 RRC连接重配置信令。
由于基站在步骤 206中获知了该用户设备不能持续监听 PDCCH信令的 能力, 因此不对该用户设备进行持续调度, 而是在上一次向该用户设备发送 PDCCH信令之后, 间隔一个或多个子帧 (依据用户设备上报的持续监听 PDCCH信令的最小时间间隔 )再向该用户设备发送 PDCCH信令。
步骤 209,用户设备收到 RRC连接重配置信令后,应用其中的参数配置, 向基站发送 RRC连接重配置完成信令。
步骤 210, 基站收到 RRC连接重配置完成后, 向核心网发送初始上下文 建立 p向应 ( Initial Context Setup Response )信令。
至此, 用户设备顺利接入网络, 与基站建立了 DRB, 可以与网络侧进行 数据传输。
需要说明的是, 由于用户设备不能持续的监听 PDCCH信令, 而且基站 在步骤 206才获得这个能力信息, 因此基站在步骤 202、 或 204中向用户设 备发送的 RRC信令可能违背了该限定, 此时用户设备就不可能接收到 RRC 信令, 也就不会向基站发送确认信令, 基站(釆用现有的 HARQ机制)需要 再次发送步骤 202、 204中的 RRC信令(即不持续调度该用户设备) , 直到 用户设备接收到 RRC信令,基站收到用户设备返回的确认信令后认为发送成 功。
本实施例还有其他的实现方式, 如时域处理能力信息可以是用户设备不 具备持续接收 PDSCH数据的能力的信息; 或者用户设备连续接收 PDSCH数 据的最小时间间隔; 或者用户设备不具备在 PUCCH信令持续发送信令的能 力信息;或者用户设备不具备在 PUSCH持续发送数据的能力的信息;基站获 得用户设备的时域处理能力信息后, 需要合理的实施调度, 避免资源浪费。
本实施还有其他的实现方式, 如时域处理能力信息用低速终端、 低成本 终端、 和 /或低优先级终端来标识, 基站收到低速终端、 低成本终端和 /或低优 先级终端的标识后, 即认为用户设备不能持续的监听 PDCCH信令; 或认为 用户设备不具备持续接收 PDSCH数据的能力; 或认为用户设备不具备在 PUCCH持续发送信令的能力,基站据此实施对用户设备的调度。协议需要规 定低速终端、 低成本终端、 或低优先级终端标识所对应的传输能力信息, 例 如, 规定低速终端对应不能持续的监听 PDCCH信令, 或者低成本终端对应 不具备持续接收 PDSCH数据的能力等等,基站收到低速终端或低成本终端的 标识后, 依据对应的传输能力实施资源调度。
实施例三
长期演进系统中的部分用户设备,主要用于接收或发送小数据量的内容, 如果釆用满足现有协议规定需求的硬件和软件,这些用户设备的成本会很高, 空口资源的浪费也很严重。 因此本实施例中的用户设备只具备接收小数据量 的能力, 具体的体现在用户设备一次能够发送或接收的数据量有限制, 比如 用户设备一次只能发送或接收最大是 300比特的数据。 对于下行, 用户设备 检测出属于自己的 PDCCH信令,然后根据 PDCCH信令携带的下行链路控制 信息获知 PDSCH的频率位置、 调制和编码方案等参数, 检测出 PDSCH。 如 果用户设备一次能够接收的数据量有限制,基站在分配 PDSCH资源时需要考 虑这一限制, 避免传递过多的数据造成接收出错。 对于上行, 用户设备需要 根据 PDCCH中指示的上行授权( UL Grant ) , 在对应的时频位置上的物理上 行共享信道(Physical Uplink Shared Channel, PUSCH )发送数据, 基站获知 用户设备一次能够发送的数据量有限制的情况下, 只需分配较小的资源块以 供用户设备发送数据。
用户设备在接入网络的过程中, 可以在 RRC连接请求或 RRC连接建立 完成信令中向基站上报分配资源块限制信息, 本实施例用分配资源块限制信 息表示用户设备在一个子帧内能够发送或接收的最大数据量大小; 或者用户 设备在收到基站发送的 UE能力查询请求之后,通过 UE能力信息向基站上报 分配资源块信息。 基站收到所述信息后, 将其应用于对该用户设备的调度, 可以更加精细的划分资源块, 避免资源浪费。 同时由于用户设备在一个子帧 内能够传输的数据量有限制, 因此可以釆用处理能力低的硬件, 可以降低成 本。
由于现有的资源块分配均以 PRB ( Physical Resource Block, 物理资源块 ) 为单位, 基站可以在一个子帧内为用户设备分配一个或多个 PRB。 如果用户 设备在一个子帧内能够发送或接收的最大数据量大小有限制, 则用户设备可 以向基站上报自己在一个子帧内能够发送或接收的 PRB个数限制, 如在一个 子帧内只能接收 1个 PRB的资源,或者在一个子帧内只能发送占据一个 PRB 资源的信令或数据; 则基站在调度该用户设备时不能分配超过限制个数的 PRB。
本实施例还有其他的实现方式, 分配资源块的限制信息还可以是一个无 线帧 (在 LTE系统中, 一个无线帧等于 10个子帧, 为 10毫秒) 内用户设备 能够接收 /发送的物理资源块个数, 或者是协议预定时间内用户设备能够接收 /发送的物理资源块个数。 基站收到用户设备上报的分配资源块的限制信息, 需要据此合理调度, 在限定条件下分配资源, 避免资源浪费。
对于小数据量传输的用户设备,支持 64QAM或 16QAM调制方式并不能 改善其吞吐量, 因此用户设备不需要支持 64QAM或 16QAM调制方式(上行 /下行) 、 或者不需要支持多输入多输出技术(Multiple-Input Multiple-Output, MIMO ), 用户设备向基站发送的 RRC连接请求或 RRC连接建立完成或 UE 能力信息中携带不支持 64QAM或 16QAM调制方式(或者携带支持的调制方 式中不包括 64QAM或 16QAM )的信息、 或者不支持多输入多输出技术的信 息, 基站获知后, 向用户设备发送的数据不釆用 64QAM调制技术或 16QAM 调制技术, 或者与用户设备进行的数据传输中不釆用 MIMO技术。 由于用户 设备不支持 64QAM或 16QAM调制方式或 MIMO技术, 其处理器的处理速 度可以降低, 有助于成本的降低。
在 LTE系统中,一个子帧是一毫秒,包含两个各为 0.5毫秒的时隙(Slot ), 基站在为用户设备分配资源块时均包含两个时隙的资源。 考虑到用户设备传 输的数据量较小, 为了提高空口资源的效率, 用户设备向基站上报自己具备 接收单个时隙的资源块的能力的信息, 基站获得用户设备的能力信息后, 可 以依据数据量的大小, 更加精细的分割资源块, 可以提高空口资源的使用效 率。 相应的, 基站需要具备按照时隙分配资源块的能力。
以上所述, 仅为本发明的较佳实施例而已, 并非用于限定本发明的保护 范围。
