下面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, 都属于本发明的保护范围。
如图 1所示, 本发明实施例提供一种物理混合重传指示信道的分配方法, 包括:
11、 根据扩展参数、 PDCCH ( Phys ica l Downl ink Contro l Channel , 物理 下行控制信道)中指示的解调参考信号循环移位值以及上行数据传输块所占用 的 PRB ( Phys ica l Resource Block , 物理资源块) 的最小标号索引值, 确定 上行数据传输块所对应的 PHI CH ( Phys i ca l Hybr id ARQ Indicator Channel , 物理混合重传指示信道)索引号, 所述扩展参数包括小区专用参数和用户设备 专用参数。
12、 根据 PHICH索引号为上行数据传输块分配 PHICH。
本发明实施例的物理混合重传指示信道的分配方法的执行主体可以是基 站, 如 LTE系统中的 eNodeB ( Evolved NodeB, 演进基站 ), eNodeB为 UE ( User Equipment , 用户设备)传输的上行数据传输块分配 PHICH, 以在 PHICH反馈 上行数据传输的 ACK或 NACK信息。
由上述本发明实施例提供的技术方案可以看出,通过扩展参数与解调参考 信号循环移位值, 扩大了基站为 UE分配 PHICH信道时的调整范围。
下面,对本发明实施例物理混合重传指示信道的分配方法涉及的技术进行 筒单说明:
LTE系统中, 用户设备向基站发送数据的过程为: 用户设备从 PDCCH信道 接收基站下发的 PUSCH ( Phys ica l Upl ink Shared Channel , 物理层上行共享 信道 )调度授权命令: 基站通过物理层上行共享信道所占用资源块的最小标号 ΙρκΒ— RA和 ¾^指示的上行解调导频循环移位信息来为用户设备分配下行 PHICH 信道, 其中 IPRB— ^和¾^都在 PDCCH信道携带的物理层上行共享信道调度授权 命令中指示; 用户设备在分配的物理层上行共享信道上向基站发送数据传输 块,基站在为用户设备分配的物理层上行共享信道接收数据传输块, 并判断是 否正确接收; 如果基站接收数据传输块正确, 则在分配的物理层下行 PHICH 信道上向用户设备发送 ACK信息; 否则, 则在分配的物理层下行 PHICH信道上 向用户设备发送 NACK信息, 相应的, 用户设备在分配的下行 PHICH信道上接 收基站反馈的 ACK/NACK信息, 如果接收到 ACK信息, 用户设备确认基站已经 正确接收该数据传输块, 则不再对该数据传输块进行发送, 如果收到 NACK信 息且没有达到最大重传次数, 则向基站重复发送该数据传输块。
PHICH信道资源是以组为单位进行分配的, PHICH组的数目 NP g p H由系统广 播信令指示的信息确认。 其中, 在常规 CP ( Cyc l ic Pref ix, 循环前缀) 下每 个 PHICH组包括 8个 PHICH, 扩展循环前缀每个 PHICH组包括 4个 PHICH。
可选的, 步骤 11中, 所述扩展参数包括用户设备专用 (UE-spec if ic )参 数。
具体的,基站可以将所述用户设备专用参数通过 PDCCH或者高层信令传输 给用户设备。 所述用户设备专用参数可以占用 PDCCH 中已有字段或者新增字 段, 用户设备专用参数占用的字段可以为一个或者多个。
如, 用户设备专用参数占用的字段为 A比特, 最多可以指示 2A个值, 而 指示解调参考信号循环移位值的字段为 3比特,最多可以指示 8个(即 23 )值, 这样,用户设备专用参数值与解调参考信号循环移位值共同指示的取值范围明 显扩大, 从而, 基站为用户设备分配 PHICH信道时可以扩大调整的范围。
可选的, 步骤 11中, 所述扩展参数包括小区专用 (CELL-spec if ic )参数 和用户设备专用参数。
具体的,基站可以将所述小区专用参数通过 PDCCH传输给用户设备, 所述 小区专用参数可以占用 PDCCH中已有字段或者新增字段; 或者,通过高层信令 将所述小区专用参数配置给用户设备。
对于同一小区的不同用户设备, 小区专用参数值相同。对于不同小区的用 户设备, 小区专用参数值可以不相同, 如下文所述的小区专用参数值 k=UE所 在的 RRH ( Radio Remote Head, 射频拉远头)所允许容纳的 UE个数的上限值。 对于不同小区的用户设备, 小区专用参数值也可以相同, 即当小区专用参数值 为常数值, 如下文所述的小区专用参数值 k= 2 NsFHICH , 此时, 基站和用户设备 可以预先协商好 k值, 则基站可以不再将小区专用参数传输给用户设备。
扩展参数包括小区专用参数和用户设备专用参数时,可以扩大扩展参数值 与解调参考信号循环移位值共同指示的取值范围,从而,基站为用户设备分配 PHICH信道时可以扩大调整的范围。
而且, 扩大扩展参数与解调参考信号循环移位值共同指示的取值范围时, 通过小区专用参数可以节约用户设备专用参数占用字段的比特数。如,用户设 备专用参数占用字段的比特数为 1比特, 最多可以指示 2个值(如 0或 1 ), 指示解调参考信号循环移位值的字段为 3比特,最多可以指示 8个值(如 0_7 ), 利用小区专用参数, 如小区专用参数为 8 , 扩展参数包括小区专用参数和用户 设备专用参数时, 扩展参数指示 1个值, 如 0或 8 ( 0或 1乘以 8 ), 则扩展参 数与解调参考信号循环移位值共同指示的取值可以取 0_15。 可见, 不需要增 加用户设备专用参数占用字段的比特数,也可以适当的扩大扩展参数与解调参 考信号循环移位值共同指示的取值范围。
可选的, 所述确定所述上行数据传输块所对应的 PHICH索引号具体包括: 通过下面的公式确定上行数据传输块所对应的 PHICH索引号, PHICH索引
号包括索引组号以及索引序号:

区中任意一个 RRH所允许容纳的 UE个数的上限值作为小区专用参数 k。 可选的, 小区专用参数值和用户设备专用参数值有以下几种取值方式,但 不限于此:

,或者, 小区专用参数值 k=分组包含用户设备个数的最大值。
其中, 用户设备的分组不仅仅限制于上述 2种形式。
通过使用户设备组内的用户设备使用相同的 PMI, 用户设备可以使用相同 的预编码矩阵和 DmRS ( Demodulation Reference Signal, 解调参考信号), 有利于同一用户设备组内的用户设备使用相同的 DmRS来解调承载在数据信道
区域内的信息(例如使用相同的 DmRS解调在数据信道区域内的资源区域上 7| 载的 DCI ) , 从而可以提高数据信道区域的资源利用率。
而且, 可以知道, 基站和用户设备在小区专用参数的取值, 用户设备专用 参数的取值, 计算方法, 需要保持一致, 从而, 通过公式(1 ), 基站可以确定 上行数据传输块所对应的 PHICH ,通过公式( 1 ) ,用户设备可以在确定的 PHICH 信道中获取到网络侧对当前数据传输块的应答反反馈。

小区专用参数 k值可以定义为 2NSF , 或者为 UE组内最大的 UE数。 eNodeB 可以将 ng值、 k值在 PDCCH中传递给 UE 通过下面的公式确定上行数据传输块所对应的 PHICH索引号:
group _「T _, . ^lmnH Ngr°Up -μΤ N grOUp

= IIPRB_RA Npg™cP H J+ nDMRS + k · ng )}mod 2NS P F HICH 公式( 4 ) 假设: 指示 nDMRS值的字段为 3比特(nDMRS为可以取 0—7), 而且, SN^01为
8
如果 UE为组 0时, 则 ng取值 =0, 此时 nDMRS+k.ng仍取 0—7 如果 UE为组 1时, 则 取值 =1, 此时 MRS + k'ng就可以取 0—15 如果 UE为组 1时, 则 取值 =2, 此时 MRS + k'ng就可以取 0—23 可见, nDMRS +k 'ng的取值范围明显扩大, 从而,基站为 UE分配 PHICH信道时 可以扩大调整的范围。
UE可以在确定的 PH I CH上进行 ACK/NACK检测, 以获知基站对当前上行数 据传输块的应答反馈信息。
