本发明涉及通信领域, 特别涉及一种确定功率调整值的方法和用户 设备。
背景技术
在增强的长期演进(LTE-A: Advanced Long-term Evolution)系统中, 采用了载波聚合技术,并且在每个服务小区上进行独立的功率上行发送信 号的功率控制, 具体的功率控制方法为:
物理上行共享信道 (PUSCH: Physical Uplink Shared Channel) 的功 率控制:
当在服务小区 c上只有 PUSCH传输时, 用户设备在第 i个子帧在服 务小区 c上的 PUSCH的发送功率为:

目前, Rel8/9的用户设备可以在任何一个有 PUSCH数据和 SRS传 输的子帧确定其功率调整值 。
但是在实现本发明的过程中发明人发现: 在 Rd-10中, 为了给用户 设备提供更高的传输速率引入了载波聚合技术。 考虑到业务量的变化, 用户设备不需要在任何时刻都使用所有为其配置的载波进行上行数据的 发送和下行数据的接收。为了使用户设备能够更好的节省电能,在 Rd-10 中针对载波聚合定义了次服务小区的激活和去激活机制。 当次服务小区 被去激活之后, 用户设备将不再监听该次服务小区的 PDCCH, 同时也不 会在该次服务小区上进行上行传输,包括 PUSCH数据传输和 SRS的传输。
当次服务小区被去激活之后,目前还没有有效的方法确定 PUSCH和 SRS发送功率的功率调整值。
应该注意, 上面对技术背景的介绍只是为了方便对本发明的技术方 案进行清楚、 完整的说明, 并方便本领域技术人员的理解而阐述的。 不 能仅仅因为这些方案在本发明的背景技术部分进行了阐述而认为上述技 术方案为本领域技术人员所公知。 发明内容

下面结合附图对本发明的各种实施方式进行说明。 这些实施方式只 是示例性的, 不是对本发明的限制。 为了使本领域的技术人员能够容易 地理解本发明的原理和实施方式, 本发明的实施方式以 LTE/LTE-A系统 中的用户设备确定功率调整值为例进行说明, 但可以理解, 本发明并不 限于上述系统, 对于涉及功率调整值的确定的其他系统均适用。
在公式 (1 ) ~ (3 ) 中, 发送功率调整值 由基站控制且有两种调 整方式。基站会为用户设备的服务小区配置该发送功率调整值 的功率 调整方式:
方式一: 累积方式, 即基站采用相对值功率控制指令指示用户设备 (UE) 在上次发送功率基础上做进一步的调整。 具体方式为:
fc (0 = fc (i _ 1) + ^PUSCH,c ('· - ^PUSCH ) (4 ) 方式二: 绝对值方式, 即基站采用绝对值功率控制指令控制用户设 备 UE的发送功率。 具体方式为:
Figure imgf000006_0001
在上述公式(4)和(5 )中, USCH,。表示基站发送的功率控制值; 为一时间常数; 对于频分双工 (FDD, Frequency Division Duplexing) 系 统, PUSCH的取值为 4; 对于时分双工 (TDD, Time Division Duplexing) 系统且 TDD的配置为 1-6时, 的取值如表 1所示; 对于 TDD系统 且 TDD的配置为 0时, 如果 PDCCH DCI format 0/4调度的 PUSCH数据 的传输在子帧 2或子帧 7且 DCI formatO/4中上行索引 (UL index) 的最 最低 (有效) 位 (LSB, Least Significant Bit) 的一个比特设置为 1时,

表 1
Figure imgf000006_0002
当用户设备 UE没有进入非连续接收(DRX: Discontinuous Reception) 状态时,该用户设备 UE会在每个子帧解码物理下行控制信道(PDCCH)。 当解码得到功率控制值 useH,。后, 该用户设备 UE会根据基站为其次服务 小区 c配置的功率调整方式来设置该次服务小区 c的功率调整值。
当满足下面三个条件时,如果基站为该用户设备 UE的次服务小区 c 配置的功率调整方式为累积方式, 则该用户设备 UE设置 US ,。为 0; 如 果基站为该用户设备 UE的次服务小区 c配置的功率调整方式为绝对值方 式, 则该用户设备 UE设置 '): ^'-1)。 条件 1:用户设备 UE没有解码得到针对次服务小区 c的功率控制命令; 条件 2: 用户设备进入 DRX状态;
条件 3 : 当前子帧不是时分双工 (TDD: Time Division Duplexing) 系统中的上行子帧。
通过上述设置方式, 对于 Rel8/9的用户设备 UE可以在任何一个有
PUSCH和 SRS传输的子帧确定其次服务小区的功率调整值 。
但是, 在 Rel-10中, 为了给用户设备提供更高的传输速率引入了载 波聚合技术。 为了使用户设备能够更好的节省电能, 在 Rd-10中针对载 波聚合定义了次服务小区的激活和去激活机制。 当基站为用户设备配置 的次服务小区被去激活之后, 该用户设备将不再监听该次服务小区的 PDCCH, 同时也不会在该次服务小区上进行上行传输, 包括 PUSCH数 据传输和 SRS的传输。
当该次服务小区被去激活之后, 目前标准中还没有定义用户设备 UE 如何设置功率调整值。 这样当该次服务小区被激活之后, 如果用户设备 UE在该次服务小区上的功率调整方式为累计方式, 无论有没有收到功率 控制命令, 该用户设备 UE将无法确定在该次服务小区上的功率调整值 氣如果该用户设备 UE在该次服务小区上的功率调整方式为绝对值方 式, 如果该用户设备 UE没有收到功率控制命令, 那么该用户设备 UE也 无法确定该服务小区上的功率调整值 。
针对上述问题, 本发明实施例给出了基站为用户设备配置的次服务 小区被去激活的情况下确定上行共享信道和上行探听参考信号的功率调 整值的方法和装置。 以下参照附图对本发明实施例进行详细说明。

在本实施例中, 基站可预先设置该用户设备的该次服务小区的功率 调整方式。
这样, 在该基站为用户设备配置的次服务小区进入去激活状态后, 即在去激活状态期间, 在每一个子帧内, 该次服务小区的功率控制值 USC¾c或者功率调整值可由用户设备自己实现, 并且可将该功率控制值 US c或者功率调整值设置为任意值, 解决了在次服务小区进入去激活 状态后无法确定该次服务小区的功率调整值的问题。
如上所述, 该次服务小区的功率调整方式可包括累积方式, 采用这 种功率调整方式时, 该用户设备 UE可设置该次服务小区的功率控制值, 该功率调整值用 ^puseH,。表示, 然后该用户设备 UE根据设置的该功率控制 值 ^USC¾c来确定在每个子帧内的功率调整值, 例如, 当前子帧为第 i 帧 时, 采用公式 (4 ) 可计算获得在当前子帧内该次服务小区的功率调整值

在步骤 101中,在该次服务小区 c的功率调整方式为绝对值方式时, 在每一个子帧内, 该用户设备 UE可将该次服务小区的当前子帧的功率调 整值设置为该当前子帧的前一个子帧的功率调制值, 例如, 若当前子帧 为第 i子帧,则 ^ϋ ^'—1) , 表示第 i子帧的功率调整值, 表 示第 i- i子帧的功率调整值。
在本实施例中, 在该次服务小区被激活后, 该用户设备 UE重置该次 服务小区 c的功率调整值。 其中, 该用户设备 UE可将功率调整值重置为
0, 即 =0。
在本实施例中, 该方法还可包括: 该用户设备 UE判断该次服务小区 是否进入去激活状态; 若判断结果为是, 则该用户设备 UE根据预置的该 次服务小区的功率调整方式设置该次服务小区 c 的功率控制值或者功率 调整值。

由上述实施例可知, 用户设备的第一判断单元 703判断次服务小区 是否进入去激活状态, 若判断结果为是, 则设置单元 701 根据预置的该 次服务小区的功率调整方式设置该次服务小区的功率控制值或功率调整 值, 在该功率调整方式为累积方式时, 确定单元 702还根据设置单元 701 设置的功率控制值确定该次服务小区在每一子帧内的功率调整值。 重置 单元 704重置该功率调整值;
在本实施例中, 设置单元 701可任意设置该次服务小区在每一子帧 内的功率控制值和功率调整值, 如设置该功率调整值 ^puseH,。=0, 或者在 当前子帧为第 i子帧时, 设置该次服务小区在当前子帧的 ^^^ ^(^1)。 在本实施例中, 重置单元 704可重置该次服务小区的功率调整值, 该功 率调整值可重置为 0; 如当前子帧为第 i子帧, 重置的该次服务小区在当 前子帧的功率调整值 (^ 。
由上述实施例可知, 在基站为用户设备配置的次服务小区进入去激 活状态后, 在每一个子帧内, 该用户设备可自行设置该次服务小区的功 率控制值 ^puseH,c或者功率调整值, 其中, 可将功率控制值设置为 0, 即
^PUSCH- =0; 可将该功率调整值设置为 ^^^^( 1), 解决了在次服务小区 进入去激活状态后无法确定该次服务小区的功率调整值的问题。 此外, 在该次服务小区被激活后, 还可重置该功率调整值。
