Description

中继配置方法和设备 本申请要求 2013 年 06 月 27 日提交中国专利局、 申请号为 201310263269.4, 发明名称为《中继配置方法和设备》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 本发明涉及通信技术领域, 特别涉及一种中继配置方法和设备。
背景技术 随着 LTE ( Long Term Evolution, 长期演进)技术的发展, 用户对无线 通信覆盖范围的需求也在不断提高。 为了扩大无线通信的覆盖范围, LTE 技术引入了无线中继 (Relay )技术, 在基站与终端设备进行通信时并不直 接发送信号,而是通过 Relay对信号进行处理后再转发。 Relay技术包括 RN ( Relay Node, 中继节点)与基站之间的通信以及 RN与其覆盖范围下的终 端设备之间的通信, 其中, 基站与 RN之间的链路称为回程链路, RN与终 端设备之间的链路称为接入链路。
现有技术中, 在部署通信网络之前, 需要对回程链路和接入链路的频 谱资源以及 Relay的双工模式进行预先配置, 而在后续的通信过程中, 回程 链路和接入链路使用的频谱资源以及 Relay的双工模式将不再发生变化。
在实现本发明的过程中, 发明人发现现有技术至少存在以下问题: 当 Relay固定釆用频分双工模式,且接入链路的频带与回程链路的频带 相同或相邻时, 会造成信号干扰, 甚至无法正常工作; 或者当 Relay固定釆 用时分双工模式时, 会造成接入链路和回程链路未使用的频带资源的浪费, 降低了频谱资源利用率。 而当出现上述情况或者通信网络的负载情况和干 扰情况发生变化时, 通信网络不能灵活配置, 进而降低了网络性能。 发明内容 为了解决现有技术的问题, 本发明实施例提供了一种中继配置方法和 设备。 所述技术方案如下:

411 : 当该第一确定频带和该第二确定频带相等, 且根据该 Relay支持 的双工模式能力确定该 Relay支持时分双工模式时,配置装置将双工模式确 定为时分双工模式, 执行步骤 414 , 否则, 执行步骤 412;
如步骤中将 fl确定为第一确定频带, f4确定为第二确定频带, 当 fl与 f4的频带间隔等于预设间隔 -20MHz时, 表明 fl与 f4相等, 此时, 将双工 模式确定为时分双工模式, 避免相同频带上的信号干扰。
412: 当该第一确定频带和该第二确定频带为相邻频带, 该邻频保护间 隔与该第一确定频带和该第二确定频带的总带宽的比例属于预设比例范 围,且根据该 Relay支持的双工模式能力确定该 Relay支持预留保护频带的 频分双工模式时, 配置装置将双工模式确定为预留保护频带的频分双工模 式, 执行步骤 414, 否则, 执行步骤 413 ;
当 fl与 f4的频带间隔等于 0MHz时, 表明 fl与 f4为相邻频带, 当该 邻频保护间隔与该第一确定频带和该第二确定频带的总带宽的比例属于预 设比例范围时, 基站将双工模式确定为预留保护频带的频分双工模式, 避 免了邻频干扰。
优选地, 该预设比例范围为 10%左右, 既可以避免邻频干 ·ί尤, 又可以 避免频谱资源的浪费。

其中, 在将该接入链路和该回程链路的频带配置为按照第一确定频带 和第二确定频带进行工作, 当配置结果中的目标双工模式为预留保护频带 的双工模式时, 基站在第二确定频带中预留保护间隔之外的频带上与 Relay 进行通信, 而当目标双工模式为频分双工模式时, 基站在第二确定频带上 按照现有方式与 Relay通信。
图 4b是本发明实施例提供的频带切换示意图, 如图 4b所示, Relay釆用 时分双工模式, 在切换频带之前, 回程链路的频带为 f2, 接入链路的频带为 Ω, 而当 £2的负载增加, 而频带 β的负载减少时, 可以将第二确定频带配置 为 β , 即双工模式不变, 回程链路的频带为 β , 接入链路的频带为 f2。
在 Relay和基站根据该配置结果对该双工模式进行切换时, 需要根据原 有双工模式和配置结果中的目标双工模式进行配置, 具体可以为以下几种 情况:
(一) 当原有双工模式为时分双工模式, 而目标双工模式为频分双工 模式时, 则取消回程链路所占子帧的限制、 回程链路的 PDSCH ( Physical Downlink Shared Channel, 物理下行共享信道)的起始位置的限制, 和 Relay 的 PDCCH ( Physical Downlink Control Channel, 物理下行链路控制信道) ; 由于在时分双工模式中需要配置回程链路所占子帧, 如多播 /组播单频 网络 MBSFN子帧, 以及 Relay的 PDCCH, 还需要对 PDSCH的起始位置进行 限制, 而在频分双工模式中, 回程链路不需要配置子帧, 基站利用普通的 控制信道与 Relay进行通信即可, 因此, 在切换双工模式时取消回程链路所 占子帧的限制、 回程链路的 PDSCH的起始位置的限制和 Relay的 PDCCH。
图 4c是本发明实施例提供的双工模式切换示意图, 如图 4c所示, 在进 行切换之前, Relay釆用时分双工模式, 回程链路的频带为 f2, 接入链路的 频带为 , 而当 £2的负载增加, 而频带 f4的负载减少时, 可以将第二确定频 带配置为 f4, 由于 f4与 £2的频带间隔大于邻频保护间隔, 则可以将目标双工 模式确定为频分双工模式, 即 Relay釆用频分双工模式, 回程链路的频带为 f4, 接入链路的频带为 f2, 此时, Relay的双工模式、 回程链路的频带和接 入链路的频带均发生变化。
(二) 当原有双工模式为频分双工模式, 而目标双工模式为时分双工 模式时, 则配置回程链路所占子帧的限制、 回程链路的 PDSCH的起始位置 的限制和 Relay的 PDCCH;
由于在频分双工模式中, 回程链路不需要配置子帧, 基站利用普通的 控制信道与 Relay进行通信即可, 而在时分双工模式中需要配置回程链路所 占子帧, 如多播 /组播单频网络 MBSFN子帧, 以及 Relay的 PDCCH, 还需要 对 PDSCH的起始位置进行限制, 因此, 在切换双工模式时, 配置回程链路 所占子帧的限制、 回程链路的 PDSCH的起始位置的限制和 Relay的 PDCCH。
(三) 当原有双工模式为时分双工模式, 而目标双工模式为预留保护 频带的频分双工模式时, 则取消回程链路所占子帧的限制、 回程链路的 PDSCH的起始位置的限制和 Relay的 PDCCH,并设置回程链路的频域的起始 位置和终止位置;
由于在时分双工模式中, 需要配置回程链路所占子帧以及 Relay的 PDCCH, 还需要对 PDSCH的起始位置进行限制, 而不需要对回程链路的频 域的起始位置和终止位置进行设置, 而在预留保护频带的频分双工模式中, 回程链路不需要配置子帧,基站利用普通的控制信道与 Relay进行通信即可, 但需要对回程链路的频域的起始位置和终止位置进行设置, 因此, 在切换 双工模式时取消回程链路所占子帧的限制、 回程链路的 PDSCH的起始位置 的限制和 Relay的 PDCCH, 并设置回程链路的频域的起始位置和终止位置。
(四) 当原有双工模式为频分双工模式, 而目标双工模式为预留保护 频带的频分双工模式时, 则设置回程链路的频域的起始位置和终止位置; 由于在频分双工模式中, 不需要对回程链路的频域的起始位置和终止 位置进行设置, 而在预留保护频带模式中则需要设置, 因此, 在切换双工 模式时设置回程链路的频域的起始位置和终止位置。
(五) 当原有双工模式为预留保护频带的频分双工模式, 而目标双工 模式为时分双工模式时, 则取消回程链路的频域的起始位置和终止位置, 配置回程链路所占子帧的限制、 回程链路的 PDSCH的起始位置的限制和 Relay的 PDCCH;
由于在预留保护频带的频分双工模式中, 回程链路不需要配置子帧, 基站利用普通的控制信道与 Relay进行通信即可, 但需要对回程链路的频域 的起始位置和终止位置进行设置, 而在时分双工模式中, 需要配置回程链 路所占子帧以及 Relay的 PDCCH,还需要对 PDSCH的起始位置进行限制, 而 不需要对回程链路的频域的起始位置和终止位置进行设置, 因此, 在切换 双工模式时, 取消回程链路的频域的起始位置和终止位置, 配置回程链路 所占子帧的限制、 回程链路的 PDSCH的起始位置的限制和 Relay的 PDCCH。
(六) 当原有双工模式为预留保护频带的频分双工模式, 而目标双工 模式为频分双工模式时, 则取; %回程链路的频域的起始位置和终止位置。
由于在预留保护频带的频分双工模式中需要设置回程链路的频域的起 始位置和终止位置, 在频分双工模式中, 不需要设置, 因此, 在切换双工 模式时, 取消回程链路的频域的起始位置和终止位置。
(七) 当原有双工模式为全双工模式, 而目标双工模式为时分双工模 式时, 则配置回程链路所占子帧的限制、 回程链路的 PDSCH的起始位置的 限制和 Relay的 PDCCH;
全双工模式和频分双工模式类似, 区别在于, 频分双工模式中接入链 路和回程链路工作在不同的频带, 而全双工模式中接入链路和回程链路可 以工作在相同的频带, Relay具有自干扰消除的能力。
(八) 当原有双工模式为时分双工模式, 而目标双工模式为全双工模 式时, 则取消回程链路所占子帧的限制、 回程链路的 PDSCH的起始位置的 限制, 和 Relay的 PDCCH;
(九) 当原有双工模式为全双工模式, 而目标双工模式为预留保护频 带的频分双工模式时, 则设置回程链路的频域的起始位置和终止位置;
(十) 当原有双工模式为预留保护频带的频分双工模式, 而目标双工 模式为全双工模式时, 则取消回程链路的频域的起始位置和终止位置。
可选地, 在根据配置结果对接入链路的频带、 回程链路的频带和双工 模式进行切换时, 可以通过 RRC RNReconfiguration消息来完成, 在消息中 需增加以下字段, 以实现双工模式的切换:
( 1 )设置 /取消回程链路所占子帧的限制;
( 2 )设置 /取消 PDSCH的起始位置的限制;
( 3 )设置 /取消 Relay的 PDCCH;
