Description

一种配置和确定上行循环移位跳频的方法、 系统及设备 本申请要求在 2011年 04月 19日提交中国专利局、 申请号为 201110097626.5、发明名 称为"一种配置和确定上行循环移位跳频的方法、 系统及设备"的中国专利申请的优先权, 其全部内容通过引用结合在本申请中。 技术领域
本发明涉及无线通信技术领域, 特别涉及一种配置和确定上行循环移位跳频的方法、 系统及设备。 背景技术
在目前上行解调参考符号 ( Demodulation Reference Symbol, DMRS )传输中, DMRS 序列所用的循环移位需要进行时隙级的跳频( CS hopping ), 即不同的时隙根据伪随机序列 确定其循环移位的偏移, 从而保证小区间的相互千扰随机化。
在上行传输中, 为了提高频谱效率, 可以进行多用户多天线 (Multiple-user MIMO, MU-MIMO )处理, 即多个用户设备 ( User Equipment, UE ) 占用相同的物理资源进行复 用传输。 如果复用 UE归属于同一个小区, 则可以通过 DMRS的配置(循环移位、 正交覆 盖码(OCC )等)保证不同 UE间 DMRS序列的正交性。 如果 UE归属于不同的小区, 则 进行 MU-MIMO复用较为复杂。
上行循环移位跳频图样对于一个小区内的所有 UE都是相同的, 但不同小区的 UE其 上行循环移位跳频图样则不同。 即使基序列相同, 两个时隙之间的上行循环移位跳频对于 不同的小区各不相同, 此时就不能利用 OCC等基于时隙的正交码来获得两个小区 DMRS 序列之间的正交性,基于循环移位的正交性也难以得到保证。此时, 归属于两个小区的 UE 就难以进行 MU-MIMO以提高频谱效率。
目前如果复用 UE归属于不同的小区, 即使将其 DMRS基序列配置成相同的, 由于釆 用不同的上行循环移位跳频图样, 也无法通过不同的循环移位或者 OCC保证其正交性, 此时就无法有效的支持小区间的多用户复用。
但是目前还没有为 UE配置上行循环移位跳频的方案, 如果复用 UE归属于不同的小 区, DMRS序列正交性难以保证, 从而影响 MU-MIMO的性能。 发明内容

本发明实施例中, 网络侧向用户设备发送上行循环移位跳频配置信息, 用于指示用户 设备根据上行循环移位跳频配置信息确定为其配置的上行循环移位跳频。 由于能够将上行 循环移位跳频配置发送给 UE, 从而可以为 UE配置上行循环移位跳频。
实施中, 本发明实施例中的用户设备可以是需要进行 MU-MIMO复用的用户设备, 也 可以是其他需要单独进行上行循环移位跳频配置的用户设备。
下面结合说明书附图对本发明实施例作进一步详细描述。
在下面的说明过程中, 先从网络侧和用户设备侧的配合实施进行说明, 最后分别从网 络侧与用户设备侧的实施进行说明, 但这并不意味着二者必须配合实施, 实际上, 当网络 侧与用户设备侧分开实施时, 也解决了分别在网络侧、 用户设备侧所存在的问题, 只是二 者结合使用时, 会获得更好的技术效果。
如图 1所示, 本发明实施例提供的确定上行循环移位跳频的系统包括: 网络侧设备 10 和用户设备 20。
网络侧设备 10, 用于确定用户设备的上行循环移位跳频配置信息, 向用户设备 20发 送上行循环移位跳频配置信息。
用户设备 20, 用于根据接收到的来自网络侧设备 20的上行循环移位跳频指示信息, 确定网络侧设备 10为用户设备配置的上行循环移位跳频。

是否使用时隙级的上行循环移位跳频图样;
是否使用子帧级的上行循环移位跳频图样;
上行循环移位跳频图样生成时所用的初始值配置信息。
如果使用时隙级的上行循环移位跳频图样, 则一个子帧内两个时隙之间的循环移位需 要进行跳频。
如果使用子帧级的上行循环移位跳频图样, 则一个子帧内两个时隙的循环移位不进行 跳频, 使用相同的循环移位, 但子帧间的循环移位需要进行跳频。
较佳的, 网络侧设备 10 通过高层信令和 /或物理下行控制信道(Physical Downlink Control Channel, PDCCH )信令发送上行循环移位跳频配置信息。
其中, 高层信令和 /或 PDCCH信令发送包括三种情况:
1、 只通过高层信令发送; 2、 只通过 PDCCH信令发送; 3、 通过高层信令和 PDCCH 信令发送。
具体的, 网络侧设备 10通过独立的高层信令指示用户设备 20上行循环移位跳频配置 信息; 相应的, 用户设备 20通过独立的高层信令接收上行循环移位跳频配置信息; 或, 网络侧设备 10通过独立的 PDCCH信令指示用户设备 20上行循环移位跳频配置 信息; 相应的, 用户设备 20通过独立的 PDCCH信令接收上行循环移位跳频配置信息; 或, 网络侧设备 10通过 PDCCH信令指示用户设备 20非上行循环移位跳频配置信息 时隐性指示用户设备 20上行循环移位跳频配置信息; 相应的, 用户设备 20通过 PDCCH 信令指示用户设备非上行循环移位跳频配置信息时隐性接收上行循环移位跳频配置信息; 或, 网络侧设备 10通过高层信令和 PDCCH信令指示用户设备 20上行循环移位跳频 配置信息; 相应的, 用户设备 20通过高层信令和 PDCCH信令接收上行循环移位跳频配置 信息。
具体的信令可以是小区专属的信令, 也可以是 UE专属信令。
下面分别进行说明。
方式一、 只通过高层信令发送。
比如, 网络侧设备 10通过高层信令指示 UE其循环移位跳频的配置。
具体的, 网络侧设备 10可以通过 1比特的高层信令指示 UE是否使用循环移位跳频, 指示内容参见表 1。

表 1
如果网络侧设备 10配置用户设备 20使用循环移位跳频, 则可以将 "0" 发送给用户 设备 20;
相应的, 用户设备 20在收到 "0" 后就知道需要使用循环移位跳频, 具体使用的循环 移位跳频可以与目前系统中的方式相同, 即时隙级的循环移位跳频; 当然也可以使用子帧 级的循环移位跳频。
在只通知使用循环移位跳频, 具体使用子帧级还是时隙级, 可以预先在协议中约定或 者用其他信令指示。

Figure imgf000006_0001
表 2
如果网络侧设备 10配置用户设备 20使用循环移位跳频, 并且使用时隙级的循环移位 跳频图样, 则可以将 "01 " 发送给用户设备 20;
相应的, 用户设备 20在收到 "01 " 后就知道需要使用循环移位跳频, 并且使用子帧 级的循环移位跳频图样。
比如: 网络侧设备 10通过 PDCCH信令指示用户设备 20其他参数配置时同时隐性指 示其循环移位跳频的配置; 用户设备 20根据其他参数的配置获得其循环移位跳频的配置。
具体的, 网络侧设备 10通过 3比特的 PDCCH信令指示用户设备 20其循环移位的配 置时同时指示其循环移位跳频的配置。 比如其中某些状态指示其使用时隙级循环移位跳 频, 某些状态指示其不使用循环移位跳频, 或者釆用子帧级的循环移位跳频图样。 指示用 户设备 20其循环移位的配置可以参见表 3 ; 指示用户设备 20其循环移位的配置时同时指 示其循环移位跳频的配置可以参见表 4和表 5。

相应的,用户设备 20在收到 111后,根据表 4就知道循环移位的配置和循环移位跳频 的配置分别是什么。
需要说明的是, 本发明实施例表 2、 表 4和表 5的内容只是举例说明, 指示内容并不 局限于表 2、表 4和表 5的内容, 其他能够通过高层信令指示用户设备 20其循环移位跳频 的配置的方式都适用本发明实施例。

比如: 网络侧设备 10通过高层信令准静态的指示用户设备 20其循环移位跳频图样的 类型(时隙级或者子帧级循环移位跳频图样), 再通过 PDCCH信令指示其是否使用循环移 位跳频, 如果可以使用, 则按照高层配置进行循环移位跳频。
例如: 网络侧设备 10用 1比特高层信令指示用户设备 20是否使用循环移位跳频, 如 果使用了循环移位跳频, 则釆用方式二中的方法指示其所使用的循环移位跳频图样。
比如: 网络侧设备 10通过高层信令指示用户设备 20多个循环移位跳频所用的初始值 配置, 再通过 PDCCH信令指示用户设备 20其循环移位跳频图样生成所用的初始值配置索 引, 用户设备 20根据此索引和高层信令获得其循环移位跳频图样生成所用的初始值。

基于同一发明构思, 本发明实施例中还提供了网络侧设备、 用户设备、 配置上行循环 移位跳频的方法和确定上行循环移位跳频的方法, 由于这些设备和方法解决问题的原理与 确定上行循环移位跳频的系统相似, 因此这些设备和方法的实施可以参见系统的实施, 重 复之处不再赘述。
