循环移位序列跳变处理、 循环移位序列值获取方法及装置 技术领域 本发明涉及通信领域, 具体而言, 涉及一种循环移位序列跳变处理、 循环移位序 列值获取方法及装置。 背景技术 高级长期演进(Long Term Evolution - Advanced, 简称为 LTE-A)系统中, 为了提 高小区边缘的传输速率, 第三代合作伙伴计划 (3GPP) 推出多点协作 (Coordinated Multi-Point Transmission and Reception, 简称为 CoMP, ) 技术, 其主要通过小区间的 协作来提高边缘用户的数据传输速率。 CoMP技术虽然改善了边缘用户的吞吐量但同 时也增加了网络系统的复杂度。
3GPP针对 CoMP技术提出了多种场景, 除了传统的同构网场景还有异构网场景。 在 CoMP技术下, 多个小区协作为同一个用户服务, 虽然提高了该用户的通信质量, 但从另一方面也降低了系统的资源利用率。 因此在 CoMP场景下, 为了提高边缘用户 吞吐量的同时保证系统的资源利用率,需要支持更多的用户(Multi-User,简称为 MU) 尤其是小区间的多个用户工作在相同或部分相同资源上, 而且这种 MU发生的机会也 远高于传统网络。
MU 的用户之间也称为配对用户, 配对用户的个数至少为两个。 当配对用户之间 占用相同的资源时, 配对用户之间可以通过相同根序列的不同循环移位(Cyclic Shift, 简称为 CS)或正交掩码 (Orthogonal Cover Code, 简称为 OCC)来实现正交复用; 当 配对用户之间占用部分相同的资源时, 配对用户之间只能通过 OCC实现正交复用。 在长期演进 (Long Term Evolution, 简称为 LTE) R10 (Release 10) 版本协议中, 循环移位序列跳变功能始终是使能的, 循环移位序列跳变图样是小区特定 (cell-specific) 的且按照每个时隙进行跳变。 现有协议中按照下式确定每个时隙所采 用的循环移位序列值: "c = ("SiRS + ! + «ΡΝ ("s ) )m0d 1 2, 其中, 《 ^就是时隙 上的循环移位序列值, 由高层通知, ^^由动态信 令通知, 《^( )代表循环移位序列跳变图样:
¾ s) =∑ 0c(8 b-"s + )-2', 其中, 伪随机序列 c( 的初始化值与小区标识和序列索引有关: cell
^mit = 25 + /J"8011 , 其中, N 11就表示小区标识, /sf^H即为序列索弓
30 图 1是相关技术中循环移位序列跳变图样的示意图, 如图 1所示, 子帧间和子帧 内部都是伪随机的, 即是按照 R10时隙级跳变的, 在相关技术新的 CoMP场景下, 循 环移位序列跳变图样是随机的, 因此, MU尤其是小区间的 MU (即配对用户) 之间 可能出现循环移位序列跳变图样不一致的现象, 这一现象会导致以下问题: 当配对用 户间是通过 CS复用时, 不同配对用户所使用的 CS会碰撞, 造成碰撞强干扰; 当配对 用户间是通过 OCC复用时,配对用户间使用不同的循环移位序列跳变图样会导致 OCC 无法正确解码的问题。 因此, 配对用户间的循环移位序列跳变图样不一致问题, 会严 重影响到 MU的用户性能以致 CoMP系统性能。 因此, 现有技术中存在由于循环移位序列跳变图样不一致影响 MU的用户性能, 以及 CoMP系统性能的问题。 发明内容 本发明提供了一种循环移位序列跳变处理、 循环移位序列值获取方法及装置, 以 至少解决现有技术中存在由于循环移位序列跳变图样不一致影响 MU的用户性能, 以 及 CoMP系统性能的问题。 根据本发明实施例的一个方面,提供了一种循环移位序列跳变处理方法,其包括: 指定配对用户间进行参考信号循环移位序列跳变所使用的循环移位序列跳变图样; 发 送用于根据指定的所述循环移位序列跳变图样对配对用户间的参考信号进行循环移位 序列跳变的指示信息。 优选地, 在指定配对用户间进行参考信号循环移位序列跳变所使用的循环移位序 列跳变图样之前, 配置以下至少一种循环移位序列图样:

实施时, 在指定配对用户间进行参考信号循环移位序列跳变所使用的循环移位序 列跳变图样之前, 该循环移位序列跳变图样可以预先配置, 例如, 可以配置以下至少 一种循环移位序列图样: 《PN(«s) = 2^。c(8N b + 2'' , 其中, 《s mod 2 = 0 ; nm (ns ) 环移位

过循环移位序列跳变图样确定循环移位序列值可以通过现有技术中的各种方式来完成 (例如, 通过预定的公式); 根据预先设置的预定步长值, 获取该参考信号剩余时隙的 循环移位序列值。 当然, 也可以通过其它更为较优的方式来获得参考信号各个时隙的 循环移位序列值, 例如, 通过对相同位置的时隙指定一个相同的循环移位序列跳变图 样, 比如, 对所有的第一时隙均指定其中的一个循环移位序列跳变图样, 对所有的第 二时隙均指定另一个循环移位序列跳变图样。 根据预先设置的预定步长值, 获取该参考信号剩余时隙的循环移位序列值的方式 也可以多种, 此处以下面两种为例进行说明: 1 )首先, 获取与指定的该循环移位序列 跳变图样相差第二预定步长值的第二循环移位序列跳变图样, 该预先设置的第二预定 波长值可以通过以下方式之一来获得: 预设的固定值, 以周期性的方式按照预定规则 循环获得, 通过预定的伪随机方式获得。 根据该第二循环移位序列跳变图样, 获取该 参考信号在各子帧剩余时隙的循环移位序列值; 2)获取与该参考信号第一时隙的循环 移位序列值相差第三预定步长值的该参考信号在各子帧剩余时隙的循环移位序列值, 其中, 第三预定步长值可以是预先设置的, 可以通过以下方式之一来获得: 预设的固 定值, 以周期性的方式按照预定规则循环获得, 通过预定的伪随机方式获得, 根据第 三预定步长值在获得的参考信号在各子帧第一时隙的循环移位序列值的基础上获得该 参考信号在各子帧剩余时隙的循环移位序列值。 在上述实施例的基础上, 本发明提供了优选的获取参考信号在各子帧第二时隙的 循环移位序列值的方式, 例如, 可以通过以下方式来获取参考信号在各子帧第二时隙 的循环移位序列值: 通过公式《PN(«S) = «PN(«S + 获取参考信号在各子帧第二时隙 的循环移位序列跳变图样, 其中, 《PN(«S - 1)为参考信号在各子帧第一时隙上的循环移 位序列跳变图样, 《PN(«S)表示该参考信号在各子帧第二时隙上的循环移位序列跳变图 样, ^^为第二预定步长值, 根据第二时隙上的循环移位序列跳变图样获取第二时隙 的循环移位序列值; 或者, 通过公式: 《。s s) = («。s s - l) + A。s )modl2获取第二时隙的 循环移位序列值, 其中, l(«s - l)表示该参考信号在各子帧第一个时隙上所使用的循 环移位序列值, 《。„ )表示该参考信号在各子帧第二个时隙上所使用的循环移位序列 值, Δ∞为第三预定步长值。 在本实施例中, 可以通过不同的方式获取参考信号第二时 隙的循环移位序列值, 由于是通过在参考信号第一时隙的循环移位序列跳变图样或循 环移位序列值的基础上加预定步长的方式获取到第二时隙的循环移位序列值的,因此, 可以保证第一时隙上的循环移位序列值与第二时隙的循环移位序列值以固定步长在跳 变, 从而实现配对用户间的循环移位序列值以相同的步长进行跳变, 确保配对用户可 以顺利地进行资源复用, 提高了配对用户的性能以及 CoMP系统的性能。
