Description

资源的调度方法及装置 技术领域
本发明涉及通信系统领域, 特别涉及一种资源的调度方法及装置。 背景技术
在 LTE系统中, 数据的传输是由基站控制的。 基站主要进行 TB ( Transport Block, 传输块) 的大小酉己置、 MCS ( Modulation and Coding Scheme , 调制编码方式) 的阶数配置和 PRB ( Physical Resource Block, 物理资源块)资源的个数配置。 其中, 基站每次分配用于传输的数据的资 源最小为 1个 PRB。 而每个 PRB能容纳 TB的大小由基站配置的 MCS来决定。
用户设备通过上报 BSR ( Buffer Status Report, 緩存状态报告) 来 使基站获得用户设备的緩沖区里剩余的待发数据量,以便接下来基站分配 相应大小的资源用于用户设备发送上行数据。由于目前完全由基站进行上 述的资源调度配置过程, 当待发送数据的大小小于基站分配的 TB大小时, 基站需要将一些与数据无关的填充比特存放至 TB中在空口进行传输;在待 发送数据需要进行多次发送时,如果首次发送所分配的资源大于首次待发 送的数据大小, 也需要对 TB进行填充, 导致该数据占用了更多的资源却没 有提高数据的可靠性, 同时也增加了用户设备功率开销。 当待发送数据的 大小大于分配的 TB大小时, 用户设备必须将数据进行分段发送, 造成了更 多的资源浪费和时延。

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它实施例,都属于本发明保护的 范围。
为使本发明技术方案的优点更加清楚,下面结合附图和实施例对本发 明作详细说明。
本实施例提供一种资源的调度方法, 如图 1所示, 所述方法包括:
101、 用户设备接收基站发送的调制编码方式 MCS阶数集合。
其中, MCS阶数集合中包含了基站允许用户设备对基站在进行数据调 度时所通知给用户设备的 MCS进行降阶或升阶的阶数。 例如, 用户设备可 以根据配置在基站进行数据调度时所通知给用户设备的 MCS的基础上降 3 阶, 或者升 3阶等。 可选地, 基站还可以为用户设备预置能够进行 MCS调整 的条件, 例如告知用户设备可以执行 MCS阶数调整, 或者待发送数据比基 站调度的 TB的值小 /大并且差值大于 /小于预设门限值、或者用户设备功率 受限, 用户设备的功率值小于 /大于基站调度的 TB中的功率指示并且差值 小于 /大于预设门限等条件, 本发明包括但不限于此。
具体地, 用户设备接收所述基站发送的携带有所述 MCS阶数集合的配 置消息,所述配置消息为无线资源控制协议 R RC消息和 /或介质访问控制层 M A C层消息, 和 /或所述用户设备接收所述基站通过物理下行控制信道 PDCCH的方式发送所述能够进行 MCS调整的条件。
其中, RRC消息或 MAC层消息可以与 PDCCH方式结合使用, 当 RRC消息或 MAC层消息与 PDCCH方式结合使用时 , RRC消息或 MAC层消息可以用来通知一 部分参数,如配置可以升阶或降阶的阶数和用户设备进行 MCS调整的条件, PDCCH用来通知另一部分参数, 比如是否允许对当前被调度的数据进行降 阶操作等。
102、用户设备根据待发送数据的值和所述基站调度的传输块 TB的值, 从所述 MCS阶数集合中选择 MCS阶数对当前 MCS进行调整。
具体地, 如果基站配置了进行 MCS调整的条件且用户设备满足所述条 件时,例如当所述待发送数据的值小于所述基站调度的传输块 T B的值时或 者当所述待发送数据的值小于所述基站调度的传输块 TB的值并且差值达 到一定门限时, 所述用户设备从所述阶数集合中选择 MCS阶数对所述 MCS 进行降阶调整。 具体例如, 基站配置的 MCS集合是最大降 3阶, 基站进行数 据调度时所通知给用户设备的 MCS为 6 , 则用户设备可以根据上述判断将 MCS的阶数调整为 6或 6-1 = 5或 6-2=4或 6- 3= 3。
通常情况下, 用户设备会将 MCS的阶数降阶调整到使得基站本次调度 所分配的 TB的值恰好能传输所述待发送数据, 因为如果再多降一阶, 基站 本次调度所分配的 TB的值小于待发送数据的量, 从而引入了新的问题。 其 中, 降阶处理可以通过增加编码的冗余和采用更低阶的调制方式来完成, 从而提升了传输的可靠性。
可替换地, 如果基站配置了进行 MCS调整的条件且用户设备满足所述 条件,例如当所述待发送数据的值略大于所述基站调度的传输块 TB的值时 或者当所述待发送数据的值大于所述基站调度的传输块 TB的值并且差值 达到一定门限时,所述用户设备从所述阶数集合中选择 MCS阶数对所述 MCS 进行升阶调整。 具体例如, 基站配置的 MCS集合中最大可以升 3阶, 基站进 行数据调度时所通知给用户设备的 MCS为 6 ,则用户设备可以根据上述判断 将 MCS的阶数调整为 6或 6 + 1 = 7或 6 + 2 = 8或 6 + 3=9。 这样就可以在减小少许可 靠性或不增加太多功耗的情况下减小由于分段发送而带来的时延和资源 浪费。
可选地, 步骤 1 02之前还可以包括: 当所述待发送数据中各个数据的 属性不同时,如各个数据来自不同的逻辑信道或者同一逻辑信道下重要性 不同, 所述用户设备为所述各个属性不同的数据分别选择不同的 MCS。 从 而可以满足不同属性数据的不同可靠性需求。
103、所述用户设备根据所述调整后的 MCS向所述基站发送所述待发送 数据。 可选地, 步骤 103之后还可以包括: 用户设备向所述基站发送指示信 息, 所述指示信息指示所述调整后的 MCS的阶数或者在基站调度时通知的 MC S阶数基础上调整的阶数,以使得所述基站根据所述调整后的 MC S阶数或 者在基站调度时通知的 MCS阶数基础上调整的阶数对所述接收到的待发送 数据进行解码。 其中, 指示信息可以在新的物理信道进行发送, 也可以在 PUSCH (Physical Uplink Shared Channel,共享物理上行信道)上进行发 送。 通过该步骤可以避免基站需要通过盲检测对接收到的数据进行解码, 从而可以减少基站的额外操作。
例如, 基站配置的允许降低 /升高阶数最大值为 3, 用户设备可以通过 01指示降低 /升高了 1阶, 通过 10指示降低 /升高了 2阶, 通过 11指示降低 / 升高了 3阶, 通过 00指示没有调整阶数。 再例如, 基站配置的允许降阶最 大值为 3和升阶最大值为 3, 用户设备可以通过 000表示没有调整阶数, 通 过 001, 010, 011, 100, 101到 110分别表示降 3阶, 降 2阶, 降 1阶, 升 1 阶, 升 2阶, 升 3阶。
本实施例提供的方法,用户设备通过对待发送数据的值和所述基站配 置的传输块 TB的值进行比较后, 对当前 MCS阶数进行调整, 然后再进行数 据传输,避免了由填充比特带来的用户设备功率开销很大或由分段发送带 来的时延、 资源浪费的问题。

可选地, 基站还可以为用户设备预置能够进行 MCS调整的条件, 例如 告知用户设备可以执行 MCS阶数调整, 或者待发送数据比基站调度的 TB的 值小 /大并且差值大于 /小于预设门限值、 或者用户设备功率受限, 用户设 备的功率值小于 /大于基站调度的 TB中的功率指示并且差值小于 /大于预 设门限等条件, 本发明包括但不限于此。
