1.28Mcps TDD系统在 R7中引入高速上行分组接入(High Speed Uplink Packet Access, HSUPA )技术, HSUPA技术分为调度传输和非调度传输, 调度 传输的流程如图 2所示, 包括以下流程:
步骤 S201、 UE通过随机接入上行控制信道 (E-RUCCH)发送资源分配请求。 UE在緩存中有上行增强数据等待发送时, 发送 E-RUCCH给 Node B, 请求 调度资源。
步骤 S202、 Node B通过 E-DCH绝对许可信道 (E-AGCH)发送资源配置信 息。
Node B根据收到的资源分配请求进行资源调度,并在 E-AGCH信道上发送 资源分配信息。 步骤 S203、 UE在 E-DCH物理上行信道 (E-DCH Physical Uplink Channel, E-DCH)上发送上行增强数据。
UE根据收到的授权信息进行增强传输格式组合 (E-TFC)选择, 选择合适的 传输块大小 (Transport Block Size, TBS)和调制方式, 之后进行编码、 调制并在 E-PUCH上发送上行增强数据。
步骤 S204、 Node 通过 E-DCH HARQ应答指示信道反馈 ACK/NACK。
Node B收到 E-PUCH后, 进行解码处理, 根据循环冗余检验 (Cyclic Redundancy Check, CRC)得到 ACK/NACK, 编码之后映射到 E-HICH上反馈给 UE。
经过上述步骤 S201-204, UE完成一次调度传输过程的数据传输。
所述 E-AGCH信道承载的信息格式如图 3所示, 其中:
PRRI是功率资源相关信息,表示 Node B调度给 UE的功率资源许可,用 5bits 表示;
CRRI是码资源相关信息, 表示 E-PUCH使用的扩频码, 其有效值为 0-30, 用 5bits表示;

RDI是资源持续指示, 用于指示资源授权生效的 ΤΉ格式以及间隔信息, 长度为 3bits。 E-AGCH是否有 RDI由高层配置决定, 并通知 UE;
ESCN是 E-AGCH的循环序列号,用于辅助进行 E-AGCH外环功率控制,统 计 E-AGCH的误块率 (BLER), 长度为 3bits;
E-HICH指示, 用于指示承载下行反馈信息的 E-HICH, 长度为 2bits;
E-UCCH个数指示, 用于指示发送的 E-UCCH的个数 (最多为 8个), 长度为 3bits;
UE ID是标识控制信息的所属 UE, 与 CRC复用 16比特的位置。
网络侧通过发送 E-AGCH信息, 利用 E-AGCH上的 3比特 RDI信息, 可以为 UE—次性分配多个 TTI的上行物理资源。
RDI指示与资源分配的映射关系如表 3所示: RDI(3bits) TTIs allocated TTI spacing

7 8 1 可以看出, 上述的技术方案中, 网络侧的资源分配方式是固定的, 分配固 定类型的资源, 例如, 发送一次 HS-SCCH 只能为 UE 分配一个 ΤΉ 的 HS-PDSCH物理资源, 发送一次 E-AGCH只能为 UE分配一个或者有限个数 的 ΤΉ的资源, 不能根据网络实际运行情况进行调整, 灵活性和通用性较差。 发明内容
有鉴于此, 本发明实施例提供一种资源分配方法及资源使用方法、装置和 系统,以解决现有技术由于资源分配方式固定而导致的灵活性和通用性较差的 问题。
本发明实施例提供一种资源分配方法, 包括:
当为目标 UE分配资源时,按照预定义的控制信道格式与预设资源类型的 对应关系确定控制信道格式;
利用确定的控制信道格式发送资源分配信息, 并向该目标 UE指示所述控 制信道的格式, 以使该目标 UE正确获取所述资源分配信息。
本发明实施例同时还提供一种资源使用方法, 包括:
截取控制信道上包含资源分配信息的数据;
依据网络侧指示, 确定所述控制信道为预定义的控制信道格式,依据预定 义的控制信道格式与预设资源类型的对应关系,确定所述数据中包含的资源分 配信息指定的资源的类型; 采用与所述预定义的控制信道格式相对应的解码方式对所述数据进行处 理, 获取所述资源分配信息;
利用所述资源分配信息指定的资源的类型所对应的使用方式,使用所述资 源。
本发明实施例还提供一种资源分配装置, 包括:
第一处理单元,用于设定预定义的控制信道格式与预设资源类型的对应关 系;
第二处理单元,用于当确定为目标用户设备 UE分配预设资源类型的资源 时, 按照相应的预定义的控制信道发送资源分配信息, 并向该目标 UE指示承 载所述资源分配信息的所述预定义的控制信道的格式, 以便该目标 UE正确获 取所述资源分配信息,并按照所述预设资源类型对应的使用方式使用所述资源 分配信息指定的资源。
本发明实施例同时还提供了一种资源使用装置, 包括:
第五处理单元, 用于截取控制信道上的包含资源分配信息的数据; 第六处理单元, 用于依据网络侧指示, 确定所述控制信道为预定义的控制 信道,依据预先设定的预设资源类型与预定义的控制信道的对应关系, 确定所 述数据中包含的资源分配信息指定的资源的类型;
第七处理单元,用于采用与所述预定义的控制信道相对应的解码方式对所 述数据进行处理, 获取所述资源分配信息;
第八处理单元,用于利用所述资源分配信息指定的资源的类型所对应的使 用方式, 使用所述资源。
本发明同时还提供一种通信系统, 包括网络侧和 UE:
所述网络侧用于: 设定预定义的控制信道格式与预设资源类型的对应关 系, 当确定为目标用户设备 UE分配预设资源类型的资源时, 按照相应的预定 义的控制信道发送资源分配信息,并向该目标 UE指示所述预定义的控制信道 的格式;
所述 UE用于: 截取控制信道上的包含资源分配信息的数据后, 依据网络 侧指示,确定所述控制信道格式为预定义的控制信道格式,依据预先设定的预 设资源类型与预定义的控制信道格式的对应关系,确定所述资源分配信息指定 的资源的类型,采用与所述预定义的控制信道格式相对应的解码方式对所述数 据进行处理, 获取所述资源分配信息, 并利用所述资源分配信息指定的资源的 类型所对应的使用方式, 使用所述资源。
从上述的技术方案可以看出, 本发明实施例定义了一种新格式的控制信 道, 可根据需要灵活设置资源分配信息, 并将控制信道格式通过设定指示信息 的方式告知 UE。 通过这种方式, 网络侧可以为 UE分配半持续资源, 指示 UE 持续利用分配的资源进行数据传输直到该 UE收到改变或者收回半持续资源的 信息为止, 网络侧减少了发送资源分配信息的次数, 节省了系统开销。 此外, 网络侧还可以通过新格式的控制信道传送资源配置信息,为 UE分配一个有效 ΤΉ的物理资源, 资源分配方式比较灵活, 并且不会影响现有资源分配方式的 执行。

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。
为了解决现有技术存在的问题, 本发明提出了一种解决方案, 网络侧通过 定义与现有控制信道格式不同的控制信道格式,承载许可 UE利用的资源的信 息 (下文统称为资源分配信息), 以指示 UE根据指定的资源进行数据传输。 具体地, 网络侧可以为 UE分配半持续资源, 由 UE持续利用指示的资源进行 数据传输直到接收到网络侧发送的用于更改或者收回资源的信息为止,也就是 说, UE在接收到网络侧发送的资源分配信息后, 利用该资源分配信息所指示 的资源进行数据的传输,直到接收到网络侧发送的指示更改或者收回资源的信 息为止, 减少了网络侧发送资源分配信息的次数, 节省了系统开销。
请参考图 4, 为本发明实施例提供的一种资源分配方法的流程图, 包括以 下步骤:
步骤 S401、 设定预定义的控制信道格式与预设资源类型的对应关系。 步骤 S402、 按照预定义的控制信道格式发送资源分配信息, 并向该目标
UE指示所述控制信道的格式。
所述预定义的控制信道格式可以是新定义的控制信道格式,也可以是现有 的控制信道格式,在本实施例以预定义的控制信道格式是新定义的控制信道格 式为例进行说明。 在为目标 UE分配预设资源类型的资源时, 参考所述对应关 系, 按照与所述预设资源类型相应的新定义的控制信道格式发送资源分配信 息。
所述新定义的控制信道格式是预先确定的,其与现有控制信道格式有所区 别, UE需要通过相应的解码方式解码才能正确获取所述资源分配信息。
本发明实施例中,先设定新定义的控制信道格式与预设资源类型的对应关 系, 在需要向 UE发送所述预设资源类型的资源时, 按照与其相对应的新定义 的控制信道格式发送资源分配信息, 并向所述 UE指示所述新定义的控制信道 的格式, 由此使得 UE可以确定承载资源分配信息的所述新定义的控制信道的 格式, 并可依据其预先存储的所述对应关系的指示,确定网络侧发送的资源分 配信息所指定的资源的类型, 于是, 可以按照该资源类型相应的资源使用方式 使用所述资源。
所述控制信道可以是 HS-SCCH 或 E-AGCH, 下面分别以控制信道为 HS-SCCH和控制信道为 E-AGCH为例, 对本发明技术方案进行详细说明。
在 HSDPA技术中, HS-SCCH是用于承载资源分配信息的控制信道, 网 络侧通过该 HS-SCCH发送资源分配信息, 为 UE分配用于进行数据传输的资 源。 本实施例定义了一种新格式的 HS-SCCH , 网络侧通过该新格式的 HS-SCCH发送资源分配信息, 进行半持续资源分配, 其过程如图 5所示, 包 括以下步骤:
步骤 S501、 建立新格式的 HS-SCCH与半持续资源类型的对应关系。
步骤 S502、 通过新格式的 HS-SCCH发送资源分配信息, 并向该目标 UE 指示所述 HS-SCCH的格式。
在下行数据到达后, 确定是否为目标 UE分配半持续资源, 若是, 则参照 上述对应关系, 按照相应的 HS-SCCH格式发送资源分配信息。
需要说明的是, 所述资源分配信息设置在预定长度的数据中, UE需要对 所述数据进行初步解析得到资源分配初始信息,并依据相应的解码方式解析才 能得到所述资源分配信息。
该资源分配信息用于指示为该 UE分配了半持续的 HS-PDSCH物理资源, 并将在所述物理资源上通过 HS-PDSCH向该 UE发送下行数据。 UE根据所述 格式指示信息确定承载所述资源分配信息的是新格式的 HS-SCCH, 则可利用 相应的解码方式对该资源分配信息进行解码,正确解读后获取所述资源分配信 息, 并可确定所述资源分配信息所指定的物理资源类型为半持续资源。 于是, 可以根据半持续资源的使用方式使用指定的资源, 在指示的物理资源上通过 HS-PDSCH信道接收数据, 并利用指定的 HS-SICH反馈 ACK/NACK。
所述半持续资源的使用方式为: UE持续在指定的物理资源上进行数据的 接收直到收到网络侧发送的改变或者收回半持续资源的信息为止。
向该目标 UE指示所述新定义的 HS-SCCH的格式, 以便与现有技术中的 HS-SCCH进行区分, 可以包括以下几种方式:
方式 1 : 在所述资源分配信息中设定预定标识。
该预定标识可以是现有技术中的无效指示,该无效指示可以是码道资源指 示的特殊值, 具体可以是指利用起始码大于终止码, 且起始码不等于" 1111", 终止码不等于 "0000"的数值。
所述码道资源指示的特殊值可以同时指示分配的 HS-PDSCH码道, 即可 以是采用现有技术中的信道化码映射关系分别确定起始码与终止码的取值, 8 个比特的码道资源指示中, 采用前 4个比特表示终止码,后 4个比特表示起始 码。例如:基站为 UE分配了 SF=16的 1号至 4号码道,现有技术中 HS-SCCH 上承载的 8比特码道资源指示为 "00000011", 本实施例的 HS-SCCH上的该指 示为" 00110000"。
或者, 所述预定标识只是一种起始码大于终止码的取值, 用来标识本实施 例的这种 HS-SCCH新格式, 不表示分配的 HS-PDSCH码道,码道资源可通过 HS-SCCH的其他信息域指示。
所述预定标识还可以是 TBS的特殊值, 具体可以是 TBS为全 0。
方式 2: 由高层配置解码格式, 并由网络侧通过无线资源控制 (Radio
Resource Control, RRC )信令将 HS-SCCH是新格式还是现有格式的事实显式 通知给 UE; 或者以某种配置生效的形式告知 UE, 例如规定当网络侧配置连 续性分组连接(Continuous Packet Connectivity, CPC )状态生效时, UE即可 确定所述 HS-SCCH格式是新格式。
方式 3: 网络侧发送的所述资源分配信息中携带的 UE ID为与新格式的
HS-SCCH对应的 ID。 或者, 网络侧发送的所述资源分配信息中携带的 UE ID 属于与新格式的 HS-SCCH对应的 ID组。
网络侧为 UE配置 N个 UE ID , 其中每一个 ID对应一种 HS-SCCH格式, 并预先通过高层信令通知 UE; 或者, 网络侧将所有的 UE ID分为 N组, 每一 组对应一种 HS-SCCH的格式, 并采用预定义或者预先通过高层信令通知或者 广播的方式通知 UE。。
方式 4:设定新格式的 HS-SCCH中,所述资源分配信息中的 UE ID与 CRC 异或后得到的比特序列与预定序列存在特定计算关系。
所述预定序列与特定计算关系为预定义或者高层配置, 例如,预定序列为 全 1序列, 特定计算关系为异或计算, 则设定当表示新格式的 HS-SCCH时, 将 UE ID与 CRC异或后得到的比特序列与全 1序列进行异或计算,即相当于: 将 UE ID与 CRC异或后的序列进行比特反转。
所述新定义的 HS-SCCH携带的资源分配信息包括: HS-PDSCH物理资源 指示、调制方式、 HCSN、 资源分配周期指示、半持续资源生效时间、 HS-SICH 指示、 TBS、 UE ID, 扩展比特、 RV信息和半持续资源的重复长度。 其中: 所述 HS-PDSCH 物理资源指示信息, 可以是在 HS-SCCH 上显示通知 HS-PDSCH的时隙和码道; 或者采用高层预定义某些参数, 并通过 HS-SCCH 通知物理资源序号的方法,具体可以是高层为 UE配置若干数量的物理资源块, 并定义每个资源块序号对应的物理资源, 所述物理资源可以包括时隙和码道, 也可以仅包括码道。基站在分配 HS-PDSCH物理资源时,进一步通过 HS-SCCH 通知物理资源序号或者物理资源序号和时隙指示。
所述调制方式是可选项,是否包含该选项取决于是否在半持续资源上是否 比如 QPSK, 则不需要承载该指示; 否则, 需要包含调制方式指示。
所述 HCSN 是可选项, 是否包含该选项取决于是否对本实施例的 HS-SCCH进行外环功控, 若进行外环功控, 则需要包含 HCSN, 否则, 则不 需要包含 HCSN。
所述资源分配周期指示信息, 用于指示分配的 HS-PDSCH物理资源的周 期,其不同数值表示不同的含义。例如: "00"表示只分配一个 ΤΉ的物理资源, "01"表示分配 20ms为周期的半持续物理资源, "10"表示分配 80ms为周期的半 持续物理资源, "11"表示分配 160ms为周期的半持续物理资源; 各个取值表示 的资源分配周期可以是预定义的, 也可以是网络侧通过 RRC信令通知给 UE。 此外,还可以利用资源分配周期指示的一个值或者利用无效的物理资源指示表 示收回半持续资源, 例如资源分配周期为" 111 "或者时隙分配指示为全 0。 所述半持续资源生效时间信息, 用于指示基站分配的半持续资源从哪个
TTI开始生效。可以由指示分配的第一个 HS-PDSCH物理资源与 HS-SCCH间 隔的 ΤΉ个数来表示,或者,需要将指示的生效时间通过预定义的公式进行计 算以获得资源生效时刻, 所述预定义的公式可以为(2*CF +/-生效时间) MOD 资源分配周期。此外, 所述资源分配信息还可以不包括所述半持续资源生效时 间信息, 而采用现有技术中的定时关系确定分配的第一个 HS-PDSCH物理资 源。
所述 HS-SICH指示, 用于指示 UE对于半持续资源上接收到的数据解码 后在哪一条 HS-SICH上进行反馈。 网络侧预先通过高层信令为 UE分配了若 干条 HS-SICH, 并分别进行了编号, 基站通过 HS-SICH上的指示通知 UE在 相应的 HS-SICH上反馈。
传输块大小信息, 是可选项,如果所述资源分配信息包含所述传输块大小 信息, 则 UE在基站分配的半持续资源上只需按照指示的 TBS进行解码即可; 如果所述资源分配信息不携带 TBS, 则 UE在基站分配的半持续资源上, 需要 利用网络侧预先配置的若干种 TBS进行盲解码。
所述扩展比特表示预留比特或者扩展空间,可以用来表示半持续资源的重 复长度或者 HS-SCCH格式指示或者留作后续扩展使用。
所述 RV信息表示在基站分配的半持续资源上的数据首次传输时采用的 RV版本, 可以采用预定义或者网络侧通过 RRC信令配置的方式进行约定。
所述半持续资源的重复长度用于指示一个资源分配周期内的资源 TTI个 数, 为可选项, 也可以预先定义或者通过高层信令配置, 而不在 HS-SCCH上 承载。
当 UE没有正确接收基站通过半持续资源发送的下行数据时,基站需要为 在半持续资源上的数据初始传输前没有 HS-SCCH指示进程号, 则重传时需要 在 HS-SCCH上通过其它方式指示是对哪一个数据块的重传。 进一步地, 数据 包累积时基站需要通过临时调度传输进行累积数据包的传输, 基站也可以为 UE分配一个 ΤΉ有效的物理资源, 且也可以不指示进程号, 而只指示为新数 据传输, 如果传输错误, 再通过上述重传的 HS-SCCH格式分配重传资源。 该 过程如图 6所示, 包括以下步骤:
步骤 S601、建立新定义的 HS-SCCH格式与一个 ΤΉ有效的资源类型的对 应关系。
步骤 S602、通过新定义的 HS-SCCH格式向该目标 UE发送资源分配信息, 并向该目标 UE指示所述 HS-SCCH的格式。
该资源分配信息用于指示为该 UE分配了一个 ΤΉ有效的 HS-PDSCH物 理资源, 并将在所述物理资源上通过 HS-PDSCH向该 UE发送下行数据。 UE 根据网络侧指示确定承载所述资源分配信息的是新格式的 HS-SCCH, 则可利 用相应的解码方式对承载在所述 HS-SCCH的信息进行解码, 获取所述资源分 配信息。 于是, 可以根据一个 ΤΉ有效的资源的使用方式使用指定的资源, 在 指示的物理资源上通过 HS-PDSCH信道接收数据, 并利用指定的 HS-SICH反 馈 ACK/NACK0
所述一个 ΤΉ有效的资源的使用方式属于现有技术, 在此不进行赞述。 向该目标 UE指示所述新控制信道的格式,以便与现有技术中的 HS-SCCH 进行区分, 可以采用指示半持续资源新格式的四种方式中的任意一种。 进一步 地,表示分配半持续资源的 HS-SCCH与本实施例分配一个 ΤΉ有效的物理资 源的 HS-SCCH可以采用相同的与现有格式区分的方式, 两种新格式的区分通 过 HS-SCCH上的特定信息域的取值, 例如: 可以通过资源分配周期指示的取 值, 或者资源分配信息中的扩展位的取值进行两种新格式的区分。
所述新定义的 HS-SCCH携带的资源分配信息包括: HS-PDSCH物理资源 指示、调制方式、 HCSN、资源分配周期指示、 TBS、 RSN、 RV版本信息、 PTR、 UE ID, 扩展位。 其中,
所述 HS-PDSCH物理资源指示、 调制方式、 HCSN和资源分配周期指示 的表示方式同分配半持续资源的 HS-SCCH相应信息域的表示方式。进一步地, 对于每一个信息域, 所述两种 HS-SCCH可以采用相同的表示方式或者各自选 择一种表示方法。
所述传输块大小信息, 用于指示数据传输采用的 TBS大小;
所述传输次数指示信息和 RV版本信息的表示方法有 2种, 表示方法 1 , 传输次数指示信息采用现有技术中的 1比特 NDI表示是否为新数据传输, RV 版本采用 3比特显式表示; 表示方法 2, 采用 1-2比特的 RSN表示传输次数, RV版本与传输次数绑定。例如用 1比特的 RSN指示第一次重传或者第二次重 传, 并预定义每次重传的 RV版本, 在 HS-SCCH上仅指示传输次数。 进一步 地,还可以利用所述一个 ΤΉ有效的物理资源进行新数据传输,利用 2比特的 RSN分别表示第一次传输、 第二次传输(第一次重传)、 第三次传输(第二次 重传)和第四次传输(第三次重传), 并分别预定义每一次传输对应的 RV版 本;
所述 PTR指针, 指示重传与上一次传输的间隔 ΤΉ个数。 进一步地, 还 可以利用所述一个 TTI有效的物理资源进行新数据传输。 当上述 RSN表示第 一次传输时, PTR指针所在信息域无效; 或者预设置 PTR指针的特定值表示 新数据传输。
所述扩展比特表示预留比特或者扩展空间, 可以用来表示 HS-SCCH格式 指示或者留作后续扩展使用。
下面分别给出具体的表示半持续资源分配的 HS-SCCH格式和一个 TTI有 效的物理资源的 HS-SCCH格式举例,分别如图 7和图 8所示。需要说明的是, 图示并不限定各个信息域的比特数或者各个信息域的级联顺序。
两种新格式与现有技术中的 HS-SCCH的区分通过 8比特的信道化码指示 表示, 当起始码大于终止码, 且起始码不等于' 1111,, 终止码不等于 '0000,时 表示新定义的 HS-SCCH格式。 并且前 4比特用来表示终止码, 后 4比特用来 表示起始码, 具体的映射含义与现有技术相同。
两种新格式都承载的信息包括:
1 ) UE ID;
2 ) 物理资源指示, 包括时隙和码道指示;
3 ) 调制方式信息, 指示调制方式为 QPSK或者 16QAM;
4 ) HCSN, 用于外环功控;
5 ) 资源分配周期指示, 2 比特对应的周期采用预定义或者高层通过 RRC信令通知的方式:
'00,表示只分配一个 ΤΉ的物理资源; '01,表示分配 20ms为周期的半持续物理资源;
'10,表示分配 80ms为周期的半持续物理资源;
'11,表示分配 160ms为周期的半持续物理资源;
资源分配周期指示可以指示只为 UE分配一个 ΤΉ有效的物理资源,也可 以指示为 UE分配周期性资源, 也即该资源分配周期指示可以指示 HS-SCCH 信道格式是与一个 ΤΉ有效的物理资源类型相对应的 HS-SCCH格式(第二控 制信道格式), 或是与半持续资源类型相对应的 HS-SCCH格式(第一控制信 道格式)。 该信息域进一步用来区分两种 HS-SCCH格式。
当 HS-SCCH为 UE分配半持续资源时, 其承载的信息还包括:
6 ) 半持续资源生效时间;
7 ) TBS;
8 ) HS-SICH指示;
9 ) 扩展位。
当 HS-SCCH为 UE分配一个 ΤΉ有效的物理资源时, 其承载的信息还包 括:
6 ) TBS;
7 ) RSN, 指示传输资源。 2比特的 RSN还可以区分一个 ΤΉ有效的资源 为新数据传输还是重传, 当为新数据传输时, 忽略 PTR指针的取值; 或 者, 限定一个 ΤΉ有效的资源只能进行重传, RSN只用 1 比特表示第 1
Figure imgf000017_0001
8 ) PTR指针;
9 )扩展位。
图 9所示为另一种 HS-SCCH新格式的举例, 它将分配半持续物理资源与 分配一个 ΤΉ有效资源的信息域承载在一起。 这种新的 HS-SCCH格式与现有 技术的区分通过 UE ID完成。 即为每个 UE分配 2个 UE ID, —个对应现有技 术的 HS-SCCH格式, 另一个对应新格式的 HS-SCCH。 当需要采用新格式分 配资源时, 使用相应的 UE ID发送资源分配信息。 其中, 码道指示 3bit用于 表示 8种码道分配方式, 分配资源最小粒度为 4个 SF=16的码道。 当比特值 等于 1时, 16个 SF=16; 当比特值 =2-3时, 2种 8个 SF=16, 1-8号码道、 9-16 号码道; 当比特值 =4-7时, 4种 4个 SF=16, 分别为 1-4号码道、 5-8号码道、 9-12号码道和 13-16号码道; 当比特值 =8时, 表示 SF=1。 其它各信息域的含 义如前所述。
在另外的实施例中,所述控制信道指的是 E-AGCH, 网络侧进行资源分配 的过程如图 10所示, 当需要为 UE分配半持续资源时, 包括以下步骤:
步骤 S1001、 建立新定义的 E-AGCH格式与半持续资源的对应关系。
步骤 S1002、通过所述新定义的 E-AGCH格式向目标 UE发送资源分配信 息, 并向所述目标 UE指示所述 E-AGCH的格式。
当然,本发明实施例还可以为目标 UE分配 N个 ΤΉ有效的物理资源,具 体方式基本相同, 因此不再赘述, 而仅以分配半持续资源为例进行说明:
向该目标 UE指示所述新 E-AGCH的格式, 指示与现有的 E-AGCH不同 的格式的方式可以包括以下几种:
方式 a、 利用资源分配信息中的某些参数的特定值进行指示。
这些参数可以是 PRRI、 CRRL TRRL RDI或 EI中的任意一个, 例如: 对 PRRI、 RDI 或 EI 进行重新定义, 确定其中的一个取值为表示新格式的 E-AGCH; 也可以将 CRRL TRRI的无效值 (例如 CRRI为全 1 , TRRI为全 0) 进行指示。也可以使用资源配置信息中时隙指示的最后一个比特进行标识, 例 如, 将最后一个比特设置为 1表示新格式的 E-AGCH; 否则, 表示现有格式的 E-AGCH。
方式 b、 由高层配置解码格式, 并由网络侧通过 RRC信令将 E-AGCH是 新格式还是现有格式的事实显式通知给 UE, 或者以某种配置生效的形式告知 UE , 例如当网络侧配置 CPC状态生效时, UE即可确定所述 E- AGCH格式是 新格式。
方式 c、 网络侧发送的所述资源分配信息中携带的 UE ID为与新格式的 E- AGCH对应的 ID。 或者, 网络侧发送的所述资源分配信息中携带的 UE ID 属于与新格式的 E- AGCH对应的 ID组。
网络侧为 UE配置了 N个 UE ID ,其中每一个 ID对应一种 E- AGCH格式, 并预先通过高层信令通知 UE; 或者, 网络侧将所有的 UE ID分为 N组, 每一 组对应一种 E-AGCH格式, 并采用预定义或者预先通过高层信令通知或者广 播的方式通知 UE。
方式 d、 设定新格式的 E-AGCH中 UE ID与 CRC异或后得到的比特序列 与预定序列存在特定计算关系。
所述预定序列与特定计算关系为预定义或者高层配置, 例如,预定序列为 全 1序列, 特定计算关系为异或计算, 则将 UE ID与 CRC异或后得到的比特 序列与预定序列进行异或计算, 即相当于: 将 UE ID与 CRC异或后的序列进 行比特反转。 所述新格式的 E-AGCH承载以下资源分配信息:
E-PUCH资源指示;
ECSN, 该参数项为可选项, 所述资源分配信息是否包含所述参数项取决 于是否对本发明实施例的 E-AGCH进行外环功控;
ENI, 该参数项为可选项, 也可以由网络侧通过高层信令配置, 而不在 E-AGCH上显式通知;
UE ID(16bit);
资源分配周期指示, 用于指示分配的 HS-PDSCH物理资源的周期, 例如: "00"表示只分配一个 TTI的物理资源, "01"表示分配 20ms为周期的半持续物 理资源, "10"表示分配 80ms为周期的半持续物理资源, "11"表示分配 160ms 为周期的半持续物理资源。各个取值表示的资源分配周期可以是预定义的,也 可以是网络侧通过 RRC信令通知给 UE。此外,还可以利用资源分配周期指示 的一个值或者利用无效的物理资源指示表示收回半持续资源,或者利用时隙为 全 0或者 CRRI为全 1指示收回半持续资源。
半持续资源生效时间,用于指示基站分配的半持续资源从哪个 ΤΉ开始生 效。 可以由指示分配的第一个 E-PUCH物理资源与 E-AGCH间隔的 TTI个数 来表示,或者, 需要将指示的生效时间通过预定义的公式进行计算以获得资源 生效时刻,所述预定义的公式可以为(2*CF +/-生效时间) MOD资源分配周期, 此外, 所述资源分配信息还可以不包括所述半持续资源生效时间信息, 而采用 现有技术中的定时关系确定分配的第一个 E-PUCH物理资源。
下面具体举例说明 E-AGCH新格式, 如图 11所示, 网络侧显式通知 UE 按照新格式进行解码:
E-AGCH上承载 1比特的 Flag(bit), 表示标志位, 用于表示其后面的两个 信息域的含义:
当 Flag=0时, 紧随其后的信息域( 5bit )表示 RDI, 其含义与现有技术相 同, 其中的 2比特为无效比特, 紧接着的信息域(2bit )表示 EI, 其含义与现 有技术相同;
当 Flag=l时, 紧随其后的信息域(5bit )表示资源生效时间信息, 之后的 信息域(2bit )表示资源分配周期, 例如, 当信息域数值为' Ό0"表示 20ms为周 期的半持续物理资源, "01"表示分配 80ms为周期的半持续物理资源, "10"表 示分配 160ms为周期的半持续物理资源, "11"表示收回半持续物理资源。
在其他实施例中, 所述资源分配信息中可以不包括标志位。
上述本发明实施例定义了一种新格式的控制信道,可根据需要灵活设置资 源配置信息, 并将控制信道格式通过设定指示信息的方式告知 UE。 通过这种 方式, 网络侧可以为 UE分配半持续资源 (将 Flag置为 1 ), 指示 UE持续利 用分配的资源进行数据传输直到该 UE收到改变或者收回资源的信息为止, 网 络侧减少了发送资源分配信息的次数, 节省了系统开销。 或者, 网络侧也可以 为 UE分配一个 ΤΉ有效的物理资源(将 Flag置为 0 )资源分配方式比较灵活, 并且不会影响现有资源分配方式的执行。
图 12示出了另一种资源分配信息的结构。
其结构与上述图 11 所示资源分配信息基本相同, 不同之处在于不包括 ECSN和 Flag, 新定义的 E-AGCH的格式可以由 TRRI的最后 1比特表示。 图 示格式仅用来分配半持续资源,一个 TTI有效的资源使用现有技术的格式进行 分配指示。
上述标志位或 FLAG均可用于指示对应与半持续资源类型的 E-AGCH的 格式(第三控制信道格式)和对应于一个 ΤΉ有效的资源类型的 E-AGCH的 格式(第四控制信道格式)。
需要说明的是, 上述描述的资源分配信息的各种结构仅是本发明的实施 例, 本领域技术人员不应将其认为是一种限制, 事实上, 各个信息域的比特数 以及排列顺序都不限于所举实例。
本发明实施例同时还提供了一种资源使用方法,该方法与图 4所示实施例 相对应, 如图 13所示, 包括以下步骤: 步骤 S1301 , 截获控制信道上包含资源分配信息的数据。
步骤 S1302、 依据网络侧的指示, 确定承载资源分配信息的控制信道为新 定义的控制信道。
步骤 S1303、依据预先设定的预设资源类型与新定义的控制信道的对应关 系, 确定资源分配信息指定的资源的类型。
所述预设资源类型与新定义的控制信道的对应关系是预先与网络侧协商 确定, 并存储的。
步骤 S1304、采用与所述新定义的控制信道相对应的解码方式对所述数据 进行处理, 获取所述资源分配信息。
步骤 S1305、 利用所述资源分配信息指定的资源的类型所对应的使用方 式, 使用所述资源。
所述控制信道可以为 HS-SCCH或 E-AGCH。
当所述控制信道为 HS-SCCH时, 上述步骤 S1102中, 依据网络侧设定 的指示, 确定承载所述资源分配信息的 HS-SCCH的方式与上述方式 1、 方式 2、 方式 3或方式 4相对应, 总的来说可以包括以下几种:
1)、 所述数据进行初步解析所得到资源分配初始信息满足预设条件。 在网络侧通过控制信道发送资源分配信息时,在不了解所述控制信道的格 式之前, UE并不能正确获取所述资源分配信息, 其所能做的仅是一些初步解 析的操作, 这点是本领域公知常识。
所述预设条件包括: 所述资源分配初始信息中的预定参数的数值为特定 值, 或者其包含的 UE ID为特定 UE ID, 或者所述 UE ID与 CRC异或后得到 的比特序列与预定序列存在异或关系。这部分内容可参照前文方法部分的方式 1、 3、 4部分的内容。
2)、接收网络侧发送的 RRC信令,或者判断某种配置是否生效,例如 CPC 状态是否生效, 若是, 则可确定 HS-SCCH是新格式的 HS-SCCH。
所述资源分配信息的结构请参考前文资源分配方法部分的内容。
当所述控制信道为 E-AGCH, 上述步骤 S1102中, 依据网络侧设定的指 示, 确定承载所述资源分配信息的 E-AGCH的方式与上述方式 a-方式 e相对 应, 在此不再赘述。 另外, 当 UE 无法正确接收网络侧通过半持续资源传输的数据而反馈 NACK时, 网络侧需要为所述半持续资源上的错误数据进行重传, 于是网络侧 会通过所述新定义的控制信道发送资源分配信息,为 UE分配一个 ΤΉ有效的 物理资源, 以便 UE在该资源上接收网络侧重传的数据。 对于 UE来说, 其需 要确定网络侧分配的资源是半持续资源或一个 ΤΉ有效的资源,本发明另外实 施例提供了一些可行的实现方式,例如:通过资源分配周期指示的数值来表示, 或者通过扩展位的具体数值来表示,具体方式可以参考前文资源分配方法部分 的内容。
本发明实施例同时还提供了实现上述部分方法流程的装置。
请参考图 14, 为本发明实施例提供的一种资源分配装置, 与上述资源分 配方法对应, 应用于网络侧, 包括: 第一处理单元 141和第二处理单元 142, 第一处理单元 141用于设定新定义的控制信道与预设资源类型的对应关系;第 二处理单元 142当确定为目标用户设备 UE分配预设资源类型的资源时,通过 相应的新定义的控制信道发送资源分配信息, 并向该目标 UE指示承载所述资 源分配信息的所述新定义的控制信道的格式, 以便该目标 UE正确获取所述资 源分配信息,并按照所述预设资源类型对应的使用方式使用所述资源分配信息 指定的资源。
本实施例中, 所述控制信道为 HS-SCCH或 E-AGCH, 所述资源可以是半 持续资源或一个传输时间间隙 ΤΉ有效资源,其格式在前文方法部分已经详细 描述过, 在此不再赘述。
图 15示出了另一种资源分配装置, 其包括第一处理单元 151和第二处理 单元 152, 第一处理单元 151的功能与第一处理单元 141的功能相类似, 第二 处理单元 152包括第三处理单元 1521和第四处理单元 1522, 其中, 第三处理 单元 1521用于通过新定义的控制信道向所述目标 UE发送资源分配信息; 第 四处理单元 1522用于通过将预定参数数值置为特定值值,或者发送 RRC信令 显式通知, 或者在所述资源分配信息中设置特定 UE ID, 或者设定 UE ID与 CRC异或后得到的比特序列与预定序列存在异或关系,向该目标 UE指示所述 新定义的控制信道的格式, 具体方式可以参考前文方法 1-方法 4部分的内容。
本发明实施例定义了一种新格式的控制信道,由此可根据需要灵活设置资 源配置信息, 并将控制信道格式通过设定指示信息的方式告知 UE。 通过这种 方式, 网络侧可以为 UE分配半持续资源, 指示 UE持续利用分配的资源进行 数据传输直到该 UE收到改变资源的资源分配信息为止, 网络侧减少了发送资 源分配信息的次数, 节省了系统开销。
针对上述资源分配过程中的资源使用方法,本发明实施例同时还提供了一 种资源使用装置, 设置于 UE中, 用于在网络侧进行资源分配过程中进行数据 传输, 请参考图 16, 所述数据传输装置包括: 第五处理单元 161、 第六处理单 元 162、 第七处理单元 163和第八处理单元 164, 其中:
第五处理单元 161 , 用于截取控制信道上的包含资源分配信息的数据; 第六处理单元 162, 用于依据网络侧指示, 确定所述控制信道为新定义的 控制信道,依据预先设定的预设资源类型与新定义的控制信道的对应关系,确 定所述数据中包含的资源分配信息指定的资源的类型;
第七处理单元 163 , 用于采用与所述新定义的控制信道相对应的解码方式 对所述数据进行处理, 获取所述资源分配信息;
