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筒单地介绍,显而易见地, 下面描述 中的附图仅仅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 出创造性劳动的前提下, 还可以根据这些附图获得其他的附图。

图 8为本发明公开的一种基站另一个实施例的结构示意图;
图 9为本发明公开的一种基站另一个实施例的结构示意图。 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他实施例, 都属于本发明保护的范围。
本发明实施例提供了一种通信方法, 适用于包括 LTE 系统在内的多种通 信系统, 能够减少由于终端与基站之间的上行 SPS 业务存在异常, 所导致的 资源浪费。 下面的描述中, 终端以 UE为例, 基站以 eNB为例, 但本发明并 不限于此。
参见图 1 , 示出了本发明一种通信方法的一个实施例的流程示意图, 本实 施例的方法可以包括:
S101 : 基站(eNB )确定满足第一条件的用户设备 UE, 该第一条件包括: UE与该 eNB之间存在半静态专用承载,且 UE与该 eNB之间的上行半静态调 度 SPS业务存在异常。
可选的, 在需要建立 UE与 eNB之间的半静态专用承载时, eNB会为 UE 配置半静态承载参数, 并将配置的半静态承载参数发送给 UE, 以完成建立该 UE与 eNB之间的半静态专用承载。 例如, 在 UE有半静态业务需求时, 由 UE向 eNB发送半静态专用承载建立请求, eNB响应 UE发送的半静态专用承 载建立请求, 将为该 UE配置的半静态承载参数返回给 UE。
其中, 半静态承载参数可以包括 SPS 小区无线网络临时标识(SPS Cell Radio Network Temporary Identifier, SPS-C-RNTI )、 SPS周期、 上行连续空包 隐式释放门限等等。 可选的, eNB将 QCI=1与配置的半静态承载参数一起发 给 UE, 以便 UE通过 QCI的值确定出需要建立的承载为半静态专用承载。 具 体建立半静态专用承载的过程与现有的建立半静态承载的过程相似,在此不再 赘述。
本实施例中, 在 UE与 eNB之间存在半静态承载之后, 如果 eNB向 UE 下发了半静态上行授权, UE才能够执行上行 SPS业务, 否则该 UE与 eNB之 间便不可能存在正常的上行 SPS业务。 同时, 即使 eNB为 UE下发了半静态 上行授权, UE与 eNB之间的上行 SPS业务也可能会出现异常。 而 UE与 eNB 之间的上行 SPS业务存在异常时, 就有可能导致资源浪费。 因此, eNB需要 确定与该 eNB之间存在半静态专用承载, 且与该 eNB之间的上行半静态调度
SPS业务存在异常的 UE, 也就是满足第一条件的 UE。
S102: eNB通知满足第一条件的 UE终止上行 SPS业务。
可选的, eNB向 UE发送第一指示消息, 该第一指示消息用于指示 UE终 止上行 SPS业务。 UE接收到该第一指示消息后, 依据该第一指示消息终止与 eNB之间的上行 SPS业务。
在本实施例中, 如果 eNB确定 UE与该 eNB之间存在半静态专用承载, 且 UE与 eNB之间的上行 SPS业务存在异常, eNB会向 UE发送第一指示消 息, 以指示 UE终止上行 SPS业务, 从而减少了由于 UE与 eNB之间的上行 SPS存在异常而导致的资源浪费。 参见图 2, 示出了本发明一种通信方法另一个实施例的流程示意图, 本实 施例为图 1所示实施例的一种具体实现方式。 本实施例的方法可以包括:
S201: eNB确定满足第一条件的 UE, 该第一条件包括: UE与该 eNB之 间存在半静态专用承载, 且该 eNB未给 UE下发半静态上行授权。
S202: eNB向 UE发送第一指示消息, 该第一指示消息用于指示 UE终止 该 UE执行的上行 SPS业务。
可以理解的, 为了实现 SPS传输, 在建立了 UE与该 eNB之间的半静态 专用承载之后, eNB通过向 UE下发半静态上行授权,为 UE分配执行上行 SPS 业务所需的上行时频资源。 具体的, eNB通过用 SPS C-RNTI进行掩码的物理 下行控制信道( Physical Downlink Control Channel, PDCCH )信息, 指示 UE 进行上行 SPS调度的激活。在该 SPS-C-RNTI进行掩码的 PDCCH信息中承载 着半静态上行授权相关信息。 相应的, UE通过属于自己的 SPS C-RNTI标识 对 PDCCH信息进行解掩码得到上行 SPS的授权信息。
为了 UE能够根据该 PDCCH信息, 确定出接收到上行 SPS激活命令, 该
PDCCH信息中固定的比特位被置为预设值。 例如, 如表 1所示, 为激活上行 SPS的 PDCCH中固定比特位的值,在该表中规定了不同的 DCI格式下各种信 息所对应的比特位的值。
例如, 在该表 1中, 下行控制信息 (Downlink Control Information, DCI ) 格式 0即 DCI format 0字段中, 为物理上行共享信道( Physical Uplink Shared Channel, PUSCH )顺序的发射功率控制 ( Transmission Power Control, TPC ) 命令, 即 TPC command for scheduled PUSCH所对应的两个比特位均填 0 , 则 在该表 1中第二行第二列填写有 "设定为 '00,,,, 即 "set to ΌΟ'" , 而该 TPC command for scheduled PUSCH则不适用于 DCI format 1/1 A中以及 DCI format 2/2A /2B的格式, 如在表 1的第一、 二行第三列以及第四列的位置处均填写有
"不适用", 即 "N/A ( Not Applicable )"。 同样的, 对于 DCI format 0格式, 解调参考信号( Demodulation reference Signal, DMRS )循环移位,即 Cyclic shift DMRS 所对应的三个比特位均设置为零; 而调制与编码策略和冗余版本, 即 Modulation and coding scheme and redundancy version的最高有效位填 0, 如表 格中第四行第二列填写有 "最高有效位" (Most Significant Bit, MSB )被设置 为零,即 "MSB is set to '0' "。同时,混合自动重传请求( Hybrid Automatic Repeat Request, HARQ )过程代码, 即 HARQ process number, 不适用于 DCI format 0 格式, 却适用于 DCI format 1/lA中以及 DCI format 2/2A /2B格式, 而且对于 DCI format 1/lA中以及 DCI format 2/2A /2B格式, 该混合自动重传请求如果 采用频分双工(Frequency Division Duplex, FDD )模式时, 三个比特位需要全 部设置为零, 而采用时分双工(Time Division Duplex, TDD )时, 四个比特位 也均被设置为零, 如在表 1的第五行第三列和第四列中均填写有 "FDD: set to '000,"以及" TDD: set to '000,,,。另夕卜,调制与编码方案即 Modulation and coding scheme, 以及冗余版本 Redundancy version均不适用于 DCI format 0格式, 却 适用于 DCI format 1/1 A中以及 DCI format 2/2A /2B格式。如,对于 DCI format 2/2A /2B 格式的调制与编码方案中, 对于激活的传输块 (For the enabled transport block ), 最高比特位被设定为零, 则在表 1中填写有 "For the enabled transport block: MSB is set to '0,"。
表 1

set to '00, 当 UE与 eNB建立了上行半静态专用承载, 且当前时刻该 eNB未对 UE 进行半静态上行授权的情况下, 该 UE可能错误的检测到半静态上行授权。 例 如, UE将非本用 SPS-C-RNTI掩码的 PDCCH错误的认为是半静态传输的激 活; 或者 UE将基站下发的其他指令解析错误, 而认为是检测到半静态激活指 令, 则 UE不断向 eNB发送数据, 但是 eNB却不会接收该 UE上传的数据, 从而造成了资源浪费。 在本实施例中, eNB通过确定与 eNB建立有半静态专 用承载, 且该 eNB未给下发半静态上行授权的 UE, 可以判断如果该 UE正在 执行上行 SPS业务,则是由于该 UE错误的检测到半静态上行授权而激活了上 行 SPS业务, 因此该 eNB可以及时终止该 UE执行的上行 SPS业务。相应的, 该 UE按照该 eNB的指示终止当前所执行的 SPS业务, 因此, 能够避免现有 的 eNB未向 UE下发半静态上行授权,而 UE错误的检测到半静态上行授权的 情况下, UE按照授权信息在固定的上行频率资源上周期性的发送或接收信息, 从而导致的资源浪费问题。应用本实施例, eNB与 UE能够保持上行 SPS的状 态一致, 也就避免了上述资源浪费, 而且还能避免 eNB将该 UE占用的上行 频率资源分配给其他 UE, 使得两个 UE占用相同的上行频率资源来进行数据 传输而导致的资源沖突问题。 可选的, 在图 2所示实施例中, eNB可以针对与该 eNB之间建立的承载 的数量较多的 UE进行是否满足的第一条件的判断和相应的后续处理,从而降 低 eNB的数据处理量和通知满足第一条件的 UE时占用的资源。以下通过图 3 所示的本发明一种通信方法的另一个实施例进行说明。本实施例的方法可以包 括:
S301: eNB在 UE集中确定满足第一条件的 UE, 该 UE集中的 UE与该 eNB之间存在多个承载。
其中, 该第一条件可以与图 1或图 2所示实施例中任意一种情况。 如, 该 第一条件可以包括: UE与该 eNB之间存在半静态专用承载, 且该 eNB未给 UE下发半静态上行授权。
S302: eNB通知 UE终止该 UE执行的上行 SPS业务。
例如, eNB向 UE发送第一指示消息, 该第一指示消息用于指示 UE终止 该 UE执行的上行 SPS业务。
可选的, eNB先确定出与基站建立有多个承载的 UE, 然后从与 eNB建立 有多个承载的 UE中, 确定出满足第一条件的 UE。 也就是说, 满足第一条件 的 UE除了与 eNB之间存在有半静态专用承载之外, 与 eNB之间还存在其他 类型的承载, 可见, 确定满足第一条件的 UE的范围缩小, 也使得确定出的满 足第一条件的 UE的数量较少。 因此, eNB向 UE发送的第一指示消息的总数 量减少, 减少了 eNB的数据处理量, 以及资源占用量。
在 eNB未给该 UE下发半静态上行授权的情况下, UE出现错误的检测 到半静态上行授权的概率较大, 因此, 应用本实施例, eNB可以发送较少数量 的第一指示消息,也可以准确的指示 UE终止未经授权而执行的 SPS业务,从 而释放未经授权而被占用的上行时频资源, 进而减少了资源沖突和资源浪费。 可选的, 当 eNB建立了 UE与 eNB之间的承载后, eNB会保存已经建立 的承载的信息,如与 eNB建立有承载的 UE的标识信息、 eNB与该 UE建立的 承载的类型、 eNB与 UE建立的承载的数量等信息中的一种或几种。 因此, 在 以上任意一个实施例中, eNB确定与该 eNB建立有半静态承载的 UE可以是: eNB查询该 eNB保存的 载的信息,如果该 eNB确定 载的信息包括该 eNB 与该 UE之间已建立的半静态专用承载的信息, 则 eNB确定该 UE与该 eNB 之间存在半静态专用承载。
可选的, 在确定与 eNB建立有多个承载的 UE时, 也可以是该 eNB查询 该 eNB保存的承载的信息, 并根据该承载的信息确定 UE与 eNB之间是否建 立有多个承载。 如, eNB可以查询保存的承载的信息中该 UE与该 eNB所建 立的承载的类型,如果 UE与该 eNB之间存在多种类型的承载, 则该 UE与该 eNB之间建立有多个承载。 或者, eNB也可以查询该承载的信息中记录的该 UE与 eNB之间已建立的承载的数量,如果 UE与 eNB之间已建立的承载的数 量大于一, 则该 UE与 eNB之间存在多个承载。
可选的, 在 eNB为 UE下发了半静态上行授权的同时, 也会修改该 eNB 所保存的上行 SPS业务的状态,其中,该上行 SPS业务的状态中包括为该 ENB 为 UE下发了半静态上行授权, 以及为 UE分配的上行时频资源等等。 因此, 在图 2和图 3所示的任意一个实施例中, 确定满足的第一条件的 UE可以是: eNB查询该 eNB保存的 载的信息和上行 SPS业务的状态信息; 如果该 eNB 确定该承载的信息包括该 eNB与该 UE之间已建立的半静态专用承载的信息, 且该上行 SPS业务的状态信息未包括该 eNB为该 UE下发的半静态上行授权, 则该 eNB确定该用户设备满足第一条件。 在现有的 LTE系统中,存在 UE错误检测到半静态上行授权时,则系统干 扰增加, 使得由 eNB激活的上行 SPS业务的数据传输异常, 从而使得传输的 数据无效, 进而引起资源浪费。
参见图 4, 示出了本发明一种通信方法另一个实施例的流程示意图, 本实 施例为图 1所示实施例的另一种具体实现方式, 能够减少由 eNB激活的上行 SPS业务的数据传输异常引起的资源浪费。 本实施例的方法可以包括:
S401: eNB确定满足第一条件的 UE, 该第一条件包括: UE与该 eNB之 间存在半静态专用承载,该 eNB已为该 UE下发了半静态上行授权,且该 eNB 与该 UE之间的上行 SPS业务的数据存在循环冗余检查(Cyclic Redundancy Check, CRC )校验错误。 S402: eNB通知 UE终止上行 SPS业务。
例如, eNB向 UE发送第一指示消息, 该第一指示消息用于指示 UE终止 上行 SPS业务。
在 eNB为 UE下发了半静态上行授权后, 如果该 UE在执行上行 SPS业 务的过程中受到干扰, 则该 UE与 eNB之间的上行 SPS业务的数据在传输过 程中就可能出现异常,例如 UE发送的上行 SPS业务的数据在传输过程中出错, eNB对接收到该上行 SPS业务的数据进行 CRC校验时, 则会出现 CRC校验 错误。
而 eNB校验出数据存在 CRC校验错误时, eNB会认为该数据无效而丟弃 该数据, 因此, 当系统存在干扰, 导致 UE向 eNB传输的上行 SPS业务数据 存在 CRC校验错误的情况下, 如果 UE继续执行上行 SPS业务, 则会导致传 输更多的无效数据, 从而引起资源浪费。 因此, 本实施例中如果 eNB 为 UE 下发了半静态上行授权, 但该 eNB针对该 UE传输的上行 SPS业务数据进行 CRC校验时出错, 该 eNB会向该 UE发送第一指示消息, 以使得该 UE终止 当前执行的上行 SPS业务, 从而避免了继续传输无效数据而导致的资源浪费。
为了避免当 UE出现一次偶然的数据传输错误, 而认为 UE当前执行的上 行 SPS业务受到干扰出现数据传输异常的情况出现, eNB可以设定上行 SPS 业务的数据存在 CRC校验错误的最大次数。 因此, eNB为 UE下发了半静态 上行授权后, 该 eNB接收该通过半静态上行授权的 UE传输的上行 SPS业务 的数据,并对该上行 SPS业务的数据进行 CRC校验,如果该上行 SPS业务的 数据进行 CRC校验出错的次数达到预设次数,则认为该 UE与 eNB之间的上 行 SPS业务存在异常。
可选的,该 eNB也可以保存承载的信息和上行 SPS业务的状态信息。 eNB 可以查询该承载的信息, 如果该承载的信息包括该 eNB与该 UE之间已建立 的半静态专用承载的信息, 则确定该 UE与 eNB之间存在半静态专用承载。 同时, 如果 eNB查询出该上行 SPS的状态信息包括该 eNB为该 UE下发的半 静态上行授权, 则认为该 UE得到了 eNB的半静态上行授权。 可选的, 在以上任意一个实施例中, eNB通知 UE终止上行 SPS业务, 包 括 eNB通知 UE释放该 UE与该 eNB之间的半静态专用承载, 和 /或, eNB通 知 UE释放该 UE与该 eNB之间的上行 SPS业务所占用的时频资源。 以下举 例说明用于指示 UE终止上行 SPS业务的第一指示消息可以有多种形式。
例如,该第一指示消息可以用于指示 UE释放该 UE与该 eNB之间的上行 SPS业务所占用的时频资源。 也就是说, 当 UE接收到该第一指示消息时, 依 据该第一指示消息释放执行上行 SPS 业务所占用的时频资源, 从而终止当前 执行的上行 SPS业务。
可选的, 该第一指示消息为现有的上行 SPS业务的去激活消息。 具体的, 该 eNB指示 UE对上行 SPS业务进行去激活, 是通过以 SPS-C-RNTI掩码的 PDCCH指示 UE的。 在该去激活上行 SPS的 PDCCH中固定比特位的值也被 设置为 LTE标准规定的值。 如表 2所示, 为 LTE标准规定的去激活上行 SPS 的 PDCCH中固定比特位的值, 例如, 该 DCI format 0字段中, 调制与编码策 略和冗余版本,即 Modulation and coding scheme and redundancy version的 5个 比特位全部为 0; 资源块分配和跳频资源分配, 即 Resource block assignment and hopping resource allocation所对应的比特位均被设置为一, 如在表 2的第 5 行第三列填写有 "Set to all Ts,,。
表 2
DCI format 0 DCI format 1A
TPC command for scheduled set to '00, N/A
PUSCH
Cyclic shift DM RS set to '000, N/A

Redundancy version N/A set to '00, Resource block assignment N/A Set to all Ts 又如, 考虑到当 UE与 eNB之间的半静态专用承载被释放后, 该 UE所执 行的半静态业务也会终止。 因此, 确定出满足第一条件的 UE时, eNB向 UE 发送的第一指示消息也可以用于指示 UE释放该 UE与该 eNB之间存在的半静 态专用承载。 可选的,在以上任意一个实施例中, eNB可以是周期性向当前满足第一条 件的 UE发送该第一指示消息, 从而能够及时终止未经授权而执行的上行 SPS 业务, 以能够最大限度的减少资源浪费。 其中, eNB发送第一指示消息的周期 可以根据需要设定。 如, 对于集群专网而言, 集群专网内大部分 UE所执行的 业务为 SPS 业务, 而集群专网内对于小区容纳的用户数量有较高要求, 也就 是说对小区规格要求较高。 为了不影响小区规格, 并能够即使释放未经半静态 上行授权的 UE所执行的上行 SPS业务, 可以将小区所属的 eNB发送第一指 示消息的周期设定为 45秒。
可选的, eNB确定满足第一条件的 UE可以是实时确定的, 也可以是按照 设定的周期进行, 该周期可以与 eNB发送第一指示消息的周期相同, 也可以 小于该 eNB发送第一指示消息的周期。 本发明还提供了一种通信装置,用于实现本发明上述实施例提供的通信方 法。 以下举例说明。
参见图 5, 示出了本发明一种通信装置一个实施例的结构示意图, 本实施 例通信装置可以包括: 确定单元 501和发送单元 502。
其中, 确定单元 501用于确定满足第一条件的 UE, 该第一条件包括: 该 UE与通信装置之间存在半静态专用承载, 且该 UE与该通信装置之间的上行 SPS业务存在异常。 发送单元 502用于向该 UE发送第一指示消息, 该第一指 示消息用于指示该 UE终止该上行 SPS业务。
该发送单元向该确定单元确定出的满足第一条件的 UE发送该第一指示消 息。 UE接收到该第一指示消息后, 终止该 UE当前所执行的上行 SPS业务, 从而释放执行该上行 SPS业务所占用的上行时频资源。
在本实施例中, 确定单元确定出与该通信装置之间存在半静态专用承载, 且与该通信装置之间的上行 SPS业务存在异常的 UE后,该发送单元会向确定 单元确定出的 UE发送第一指示消息, 以指示该 UE终止上行 SPS业务, 从而 减少了由于 UE与通信装置之间的上行 SPS存在异常而导致的资源浪费。 可选的, 该发送单元 502还用于向用户设备下发半静态上行授权。
如果该发送单元未给 UE发送半静态上行授权, 而 UE错误的检测到半静 态上行授权时, 则会造成资源沖突和资源浪费。 为了避免该种原因导致的资源 沖突和资源浪费,该确定单元 501具体用于确定与该通信装置之间存在半静态 专用承载, 且该发送单元未下发半静态上行授权的 UE。相应的, 该发送单元, 用于向与该通信装置之间存在半静态专用承载,且该发送单元未下发半静态上 行授权的 UE发送第一指示消息。
可选的, 该确定单元可以包括:
第一查询子单元,用于查询所述通信装置保存的承载的信息和上行半静态 调度业务的状态信息;

相应的,确定单元 501具体用于: 确定与该通信装置之间存在半静态专用 承载, 该发送单元已下发了半静态上行授权, 且该接收单元接收到的上行 SPS 业务的数据存在 CRC校验错误的用户设备。
例如, 该确定单元可以包括:
第二查询子单元,用于查询该通信装置保存的承载的信息和上行半静态调 度业务的状态信息;
第二校验子单元, 用于针对该上行 SPS业务的数据进行 CRC校验; 第二判断子单元,用于判断该承载的信息是否包括该通信装置与该 UE之 间已建立的半静态专用承载的信息, 该上行 SPS 的状态信息是否包括该发送 单元为该 UE下发的半静态上行授权,及该第二校验子单元针对该上行 SPS业 务的数据进行 CRC校验时是否出错, 如果该承载的信息包括该通信装置与该 UE之间已建立的半静态专用承载的信息, 该上行 SPS业务的状态信息包括该 发送单元为该 UE下发的半静态上行授权,且第二校验子单元针对上行 SPS业 务的数据进行 CRC校验时出错, 则确定该用户设备满足所述第一条件。 为了避免当 UE出现一次偶然的数据传输错误, 而认为 UE当前执行的上 行 SPS 业务受到干扰出现数据传输异常的情况出现。 可选的, 该确定单元具 体用于: 确定与所述通信装置之间存在半静态专用承载, 所述发送单元已下发 了半静态上行授权,所述接收单元接收到的上行半静态调度业务的数据存在循 环冗余检查 CRC校验错误,且 CRC校验错误的次数达到预设次数的用户设备。 例如, 该确定单元可以包括:
第三查询子单元, 用于查询该通信装置保存的承载的信息和上行 SPS 业 务的状态信息;
第三校验子单元, 用于针对该上行 SPS业务的数据进行 CRC校验; 计数器,用于累计该第三校验子单元针对该上行 SPS业务的数据进行 CRC 校验时出错的次数;
第三判断子单元,用于判断该承载的信息是否包括该通信装置与该 UE之 间已建立的半静态专用承载的信息, 该上行 SPS 业务的状态信息是否包括该 发送单元为该 UE下发的半静态上行授权,及该计数器累计的结果是否达到预 设次数,如果该承载的信息包括该通信装置与该 UE之间已建立的半静态专用 承载的信息,该上行 SPS业务的状态信息包括该发送单元为该 UE下发的半静 态上行授权, 且该计数器累计的结果达到预设次数, 则确定该 UE满足第一条 件。 可选的, 在以上任意一个实施例中, 为了能够及时终止满足第一条件的 UE所执行的上行 SPS业务, 以最大程度的减少资源浪费, 该发送单元具体用 于周期性向所述用户设备发送所述第一指示消息。 另一方面, 本发明还提供了一种基站, 参见图 7, 示出了本发明一种基站 一个实施例的结构示意图, 本实施例中该基站 700至少包括: 处理器 701和发 射器 702。
