传输资源配置方法及相关设备和通信系统
本申请要求于 2011 年 09 月 30 日提交中国专利局、 申请号为 201110304418.8、 发明名称为"传输资源配置方法及相关设备和通信系统 "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,具体涉及传输资源配置方法及相关设备和通信 系统。
背景技术
长期演进(LTE, Long Term Evolution ) 系统等通信系统能够支持时分双 工 (TDD, Time Division Duplexing )方式, 即上行链路(UL, Uplink )和下 行链路( DL , Downlink )可使用同一频率的不同时隙。 LTE TDD系统可根据 业务类型半静态配置上下行配比 (Uplink-Downlink Configuration ), 以满足不 同的上下行非对称业务需求。
目前, LTE TDD系统总共定义了 7种上下行配比, 参见表 1 , 其中 "D" 表 示下行子帧, "U" 表示上行子帧, "S" 表示特殊子帧。 从表 1可看出, 各上下 行配比方式预留给下行业务的时域资源占 40 %到 90 %。 LTE TDD系统中使用哪 种上下行配比是半静态配置的, 其中, 上下行配比指示信息携带在系统广播消 息的系统信息块 1 ( SIB1 , System lnformation Block-l )中。 SIB1的传输周期为 80ms (毫秒), 在其每个传输周期内每隔 20ms重复一次, 以保证小区所有用户 都能正确接收。

由于现有 SIB1通常是慢变的 , 为避免用户设备 ( UE, User Equipment )重 复读取相同的 SIB1而造成能源消耗, 系统还定义了 SIB1的消息变更周期, SIB1 中的信息只在一个变更周期的起始时刻发生改变并发送给 UE, 而在一个变更 周期内, SIB1中的信息不会改变。 对于处于连接态的 UE, 只需在变更周期的 起始时刻更新 SIB1 ; 对于处于空闲态的 UE, 如果有 SIB1发生改变, 现有基站 通过寻呼告知空闲态的 UE, 该空闲态的 UE在下一个变更周期的起始时刻醒来 并接收新的 SIB1。 SIB1的变更周期最短为 640ms, 最大约为 41s。
为避免小区间上下行的干扰,传统的 TDD系统通常都是大范围内的多个小 区统一使用相同的上下行配比, 且长时间不发生变化。如果要改变上下行配比 也是多个小区一起改变, 并通过中断数据传输的方式进行硬切换。 然而, 例如 在孤岛小区或低功率节点覆盖的小区, 小区间干扰影响不大, 并且在小区服务 的用户数较少的情况下, 上下行业务突发的情况会比较显著,在这些场景下如 何更有效地利用频谱资源以发挥 TDD系统特有的优势,则是一个值得研究的技 术问题。

具体实施方式
本发明实施例提供传输资源配置方法及相关设备和通信系统,以期提高传 输资源配置的灵活' \ί和频谱资源利用率。
以下分别进行详细说明。
为了使得本发明的发明目的、 特征、 优点能够更加的明显和易懂, 下面将 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, 下面所描述的实施例仅仅是本发明一部分实施例, 而非全部的实 施例。基于本发明中的实施例, 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它实施例 , 都属于本发明保护的范围。
首先说明的是,本发明实施例所指接入设备是指可实现用户设备无线接入 管理功能的接入网实体, 而接入设备在不同的网络中可能具有不同的名称、位 置和产品形态。
举例来说, 本发明下述实施例中提及的接入设备例如可以指: 演进通用移 动通信系统 ( UMTS, Universal Mobile Telecommunications System ) 陆地无线 接入网 (E-UTRAN, Evolved UMTS Territorial Radio Access Network ) 中的演 进基站(eNodeB )、 家庭基站( HeNB )或其它类型的基站; 或 UMTS陆地无线 接入网 ( UTRAN, UMTS Territorial Radio Access Network ) I GSM EDGE无线 接入网 (GERAN, GSM EDGE Radio Access Network )中的基站控制器、 或无 线网络控制器(RNC, Radio Network Controller ); 或者也可指宽带码分多址接 入( CDMA, Code Division Multiple Access ) 网络中具有高速率分组数据接入 网 ( HRPD-AN, High Rate Packet Data Access Network )接入网逻辑功能的实 体、 无线局域网 (WLAN, Wireless Local Area Network )中具有演进分组数据 网关( EPDG , Evolved Packet Data Gateway )接入网逻辑功能的实体; 微波存 取全球互通 ( WiMAX, Worldwide Interoperability for Microwave Access ) 网络 中的接入服务网络基站( ASN-BS , Access Service Network Base Station )或其 它网络中实现终端无线接入管理的实体。 本发明传输资源配置方法的一个实施例, 可包括: 接入设备通知用户设备 第二上下行配比变更周期, 其中, 该第二上下行配比变更周期小于系统消息变 更周期; 向该用户设备发送第一消息, 该第一消息携带对应第二上下行配比变 更周期的上下行配比指示。
参见图 1 , 具体步骤可包括:
101、 接入设备通知用户设备第二上下行配比变更周期;
其中, 上述第二上下行配比变更周期 (下面可简称为 TUD ) 小于系统消息 变更周期 (即小于 SIB1的变更周期), 其中, 该第二上下行配比变更周期 TUD 例如可为系统消息变更周期的 1/N倍, N为正整数, 例如 N可取值为 2、 3、 4、 8 或其它值。
在实际应用中, 例如在孤岛小区或低功率节点覆盖的小区, 小区间干扰影 响不大,在小区服务的用户数较少的情况下, 小区上下行业务突发情况会比较 显著,在上下行业务突发情况会比较显著的场景下,接入设备可定义一个比系 统消息变更周期(SIB1变更周期, 下面可简称为 TSFFIL )更短的第二上下行配比 变更周期 TUD, 系统消息变更周期 TSFFIL目前最短为 640ms, 最大约为 41s, 接入 设备定义的第二上下行配比变更周期 TUD例如可为 320ms、 160ms, 80ms, 40ms 或其它值。
其中,在 1个第二上下行配比变更周期 TUD持续时间内,对应小区的上下行 配比保持不变, 上下行配比可在每个第二上下行配比变更周期 TUD的起点发生 改变。 第二上下行配比变更周期 TUD是系统可配置的, 接入设备例如可以根据 当前的上下行业务量变化情况选择合适大小的第二下行配比变更周期 TUD, 例 如相邻两个时段(该时段例如为 40ms、 80ms、 160ms, Is或其它时间长度)之 间的上下行业务量比值的变化量越大,接入设备设定的第二上下行配比变更周 期 TUD越短(如不同的上下行业务量比值的变化量范围, 可对应不同大小的第 二上下行配比变更周期 TUD ),或,例如若小区当前激活用户数比较少(例如 1~5 个), 此时该小区上下行业务突发或波动情况可能会比较频繁, 则接入设备可 以使用较小的第二上下行配比变更 TUD; 若小区当前激活用户数比较多 (>10 个), 此时多个用户的总业务量波动可能相对变緩, 则接入设备可以使用较大 的第二上下行配比变更 TUD, 即小区不同的当前激活用户数范围, 可对应不同 的第二上下行配比变更周期 TUD。
在实际应用中, 接入设备例如可通过高层信令(或系统广播消息 )通知用 户设备当前配置的第二上下行配比变更周期 TUD。
进一步的,接入设备还可根据需要选择上下行配比变更方式, 例如若当前 小区业务波动相对比较緩慢(如业务波动量小于某设定阔值 S 1 ), 则接入设备 可选择系统消息变更周期 TSIB1作为小区上下行配比变更周期(即在每个系统消 息变更周期 TSFFIL的起始时刻可选择变更上下行配比;); 若当前小区业务波动相 对较快 (如业务波动量大于某设定阔值 S2 ), 则接入设备可釆用动态改变上下 行配比的方式(即配置一些灵活子帧 ( flexible subframe ), 接入设备可将每个 灵活子帧动态地配置成上行子帧或下行子帧); 若当前小区业务波动一般(如 波动量介于阔值 S1和阔值 S2之间 ), 则接入设备可选择小于系统消息变更周期 TSIB1的第二上下行配比变更周期 TUD作为小区上下行配比变更周期 (即在每个 第二上下行配比变更周期 TUD的起始时刻可选择变更上下行配比)。例如接入设 备可在系统广播消息中增加信息比特来指示所选择的上下行配比变更方式;或 者, 接入设备可在专用无线资源控制 ( RRC, radio resource control )信令中增 加信息比特来指示所选择的上下行配比变更方式, 以提高配置灵活性, 可实现 用户分别配置。
102、 接入设备向该用户设备发送携带对应第二上下行配比变更周期的上 下行配比指示的第一消息,以使得用户设备根据该上下行配比指示更新所述用 户设备使用的上下行配比。
其中,接入设备例如可在某个第二上下行配比变更周期的起始时刻, 向用 户设备发送的第一消息; 其中, 该第二上下行配比变更周期的起始时刻发送的 第一消息携带的上下行配比指示所指示出的(变更的)上下行配比, 在该第二 上下行配比变更周期启用。或者,接入设备可在某个第二上下行配比变更周期 的非起始时刻, 向用户设备发送的第一消息; 其中, 该第二上下行配比变更周 期的非起始时刻发送的第一消息携带的上下行配比指示所指示出的变更的上 下行配比,在该第二上下行配比变更周期的下一个第二上下行配比变更周期启 用。
在实际应用中,接入设备例如可在系统广播消息(即第一消息为系统广播 消息) 中增加对应第二上下行配比变更周期 TUD的上下行配比指示, 以通过该 系统广播消息通知用户设备当前的第二上下行配比变更周期 TUD对应的上下行 配比。或者,接入设备可在专用 RRC信令中携带对应第二上下行配比变更周期 TUD的上下行配比指示, 以通过该专用 RRC信令(即第一消息为专用 RRC信令) 通知用户设备(例如通知支持第二上下行配比变更周期 TUD的激活态用户设备) 当前的第二上下行配比变更周期 TUD对应的上下行配比。 当然接入设备也可将 对应第二上下行配比变更周期 TUD的上下行配比指示携带在其它类型的消息中 发送给用户设备。
此外, 考虑到 LTE TDD系统的兼容性问题, Rel-8/9/lO的用户设备(若其 不支持第二上下行配比变更周期 TUD )仍可使用 SIB1中携带的上下行配比指示 信息来指示上下行配比,并可按照系统消息变更周期 TSffil来更新其使用的上下 行配比, 假设该配比为 "上下行配比 -1", 而处于连接态的 Rel-11用户设备或更 高版本的用户设备(若其支持第二上下行配比变更周期 TUD ),可按照设定的第 二上下行配比变更周期 TUD来更新其使用的上下行配比, H没该上下行配比为 "上下行配比 -2"; 例如图 2所示, 在同一时刻, 上下行配比 -1和上下行配比 -2 可能不同, 由于第二上下行配比 -2的变更周期 TUD小于上下行配比 -1的变更周 期 TSffil , 因此, 使用上下行配比 -2有利于更好地适应上下行业务快速变化的场 景; 另外, 由于上下行配比 -1可体现一段时间内的平均上下行业务量情况, 因 此, 在系统消息变更时刻若上下行配比 -1发生改变, 处于连接态的 Rel-11用户 设备可优先使用更新的上下行配比 -1。 由于空闲态 Rel-11用户设备无需发送和 接收数据, 因此, 其可使用上下行配比 -1并跟踪该上下行配比 -1的变化, 此处 由于只需要连接状态的支持灵活子帧配比的用户设备更快的更新其使用的上 下行配比, 而空闲态的 Rel-11用户设备可无需按照第二上下行配比变更周期 TUD更新其使用的上下行配比, 故而可避免寻呼空闲态用户设备所带来的系统 开销, 并有利于保证后向兼容性。
在一种应用场景下, 若第一消息为系统广播消息, 由于对应第二上下行配 比变更周期 TUD对应的上下行配比指示只用于连接态的 UE, 因此当系统广播消 息携带的对应上下行配比变更周期 TUD对应的上下行配比指示发生变化时, 接 入设备可不发送寻呼告知空闲态的 UE。 若第一消息为专用 RRC信令, 则若 UE 在某个第二上下行配比变更周期 TUD的起始时刻接收到 RRC信令(该 RRC信令 携带对应的上下行配比变更周期 TUD的上下行配比指示 ), 则 UE可在该上下行 配比变更周期 TUD内启用该上下行配比指示所指示的上下行配比;如果 UE在一 个配比变更周期的其它位置(即分非起始时刻 )接收到 RRC信令(该 RRC信令 携带对应的上下行配比变更周期 TUD的上下行配比指示), 则 UE可在该上下行 配比变更周期 TUD的下一个上下行配比变更周期 TUD内启用该上下行配比指示 所指示的上下行配比。 可以理解, 接入设备通过专用 RRC信令可以为不同的 UE配置不同的上下行配比, 以便更好的进行上下行干扰管理, 可进一步增加 灵活性。
在实际应用中, 对应第二上下行配比变更周期 TUD的上下行配比指示可以 是能够指示出对应上下行配比的任何信息, 例如,对应第二上下行配比变更周 期 TUD的上下行配比指示可指示表 1中对应的上下行配比配置号 (表 1中的不同 配置号对应着不同的上下行配比)。 或者, 对应第二上下行配比变更周期 TUD 的上下行配比指示也可指示出一个相对偏差值,该相对偏差值为第二上下行配 比变更周期 TUD对应的上下行配比在表 1中对应的上下行配比配置号,与系统消 值。例如, 第二上下行配比变更周期 TUD对应的上下行配比在表 1中的上下行配 比配置号为 1 ,系统消息变更周期 TSMI所对应的上下行配比在表 1中对应的上下 行配比配置号为 3 ,则对应第二上下行配比变更周期 TUD的上下行配比指示可指 示出相对偏差值为 -2 , UE通过 SIB1可获知系统消息变更周期 TSFFIL所对应的上 下行配比在表 1中对应的上下行配比配置号, 在接收到携带对应第二上下行配 比变更周期 TUD的上下行配比指示 (偏差值 -2 ) 的消息后, 可将系统消息变更 差值(-2 ), 进而获知当前第二上下行配比变更周期 TUD对应的上下行配比(上 下行配比配置号 1 )。
可以理解,接入设备还可通过其它多种方式来指示第二上下行配比变更周 期 TUD对应的上下行配比, 上下行配比指示所指示的上下行配比与前一个第二
本发明实施例还提供一种传输资源配置方法, 可包括:
用户设备通过接入设备的通知获取第二上下行配比变更周期,该第二上下 行配比变更周期小于系统消息变更周期;该用户设备接收来自该接入设备的第 一消息, 其中, 该第一消息携带有对应该第二上下行配比变更周期的上下行配 比指示;该用户设备按照第一消息中携带的上下行配比指示更新该用户设备使 用的上下行配比。
在实际应用中, 若用户设备在第二上下行配比变更周期的起始时刻,接收 来自接入设备的第一消息; 其中, 该第一消息携带的上下行配比指示所指示出 的上下行配比, 可在改第二上下行配比变更周期启用; 或者, 若用户设备在第 二上下行配比变更周期的非起始时刻,接收来自接入设备的第一消息; 则该上 下行配比指示所指示出的上下行配比,例如可在第二上下行配比变更周期的下 一个第二上下行配比变更周期启用。
在一种应用场景下,若用户设备按照第一消息中携带的上下行配比指示更 新所述用户设备使用的上下行配比之后 ,该用户设备接收来自接入设备的系统 消息, 其中, 该系统消息携带有对应系统消息变更周期的上下行配比指示; 则 用户设备例如也可按照系统消息中携带的上下行配比指示更新所述用户设备 使用的上下行配比, 或者, 用户设备可直接忽略该系统消息携带的对应系统消 息变更周期的上下行配比指示。
在一种应用场景下, 若用户设备为支持第二上下行配比变更周期 TUD的连 接态用户设备(例如 Rel-11用户设备或更高版本的用户设备), 则其可按照第 二上下行配比变更周期 TUD和第一消息中携带的上下行配比指示来更新其使用 的上下行配比;若用户设备为可支持第二上下行配比变更周期的空闲态用户设 备(例如 Rel-11用户设备或更高版本的用户设备), 则其可按照系统消息变更 周期 TSIB1和该系统消息变更周期 TSIB1对应的上下行配比来更新其使用的上下 行配比; 若用户设备为不支持第二上下行配比变更周期的用户设备 (如
Rel-8/9/lO用户设备等), 则其可按照系统消息变更周期 TSffil和该系统消息变更 由上可见,本实施例的接入设备设定了比系统消息变更周期更短的第二上 下行配比变更周期,接入设备通知用户设备第二上下行配比变更周期, 并可在 备发送携带有对应第二上下行配比变更周期的上下行配比指示的消息,由于上 下行配比变更周期设计的更短,进而提高了传输资源配置的灵活性和频谱资源 利用率,有利于更好的适应上下行业务量波动较大的场景, 获得更好的业务自 适应。
此外, 若该第二上下行配比变更周期 TUD为系统消息变更周期的 1/N倍, N 为正整数,则接入设备可利用携带 SIB1的系统广播消息一并携带对应第二上下 行配比变更周期的上下行配比指示, 可进一步降低信令开销, 更好的保证后向 兼容性。
为便于更好的理解和实施本发明实施例的上述方案,下面还提供用于实施 上述方法的相关设备。 参见图 3、 本发明实施例提供的一种接入设备 300, 可包括: 通知模块 310 和配置模块 320。
其中, 通知模块 310, 用于通知用户设备第二上下行配比变更周期, 该第 二上下行配比变更周期小于系统消息变更周期。
其中, 第二上下行配比变更周期 (TUD ) 小于系统消息变更周期 (即小于 SIB1的变更周期 TSIB1 ),其中,该第二上下行配比变更周期 TUD例如可为系统消 息变更周期的 1/N倍, N为正整数, 例如 N可取值为 2、 3、 4、 8或其它值。
在实际应用中, 例如在孤岛小区或低功率节点覆盖的小区, 小区间干扰影 响不大,在小区服务的用户数较少的情况下, 小区上下行业务突发情况会比较 显著, 在上下行业务突发情况会比较显著的场景下, 接入设备 300可定义一个 比系统消息变更周期 (TSIB1 ) 更短的第二上下行配比变更周期 TUD, 系统消息 变更周期 Tsmi目前最短为 640ms, 最大约为 41s, 接入设备 300定义的第二上下 行配比变更周期 TUD例如可为 320ms、 160ms, 80ms、 40ms或其它值。
其中,在 1个第二上下行配比变更周期 TUD持续时间内,对应小区的上下行 配比保持不变, 上下行配比可在每个第二上下行配比变更周期 TUD的起点发生 改变。第二上下行配比变更周期 TUD是系统可配置的,接入设备 300例如可根据 当前的上下行业务量变化情况选择合适大小的第二下行配比变更周期 TUD, 例 如相邻两个时段(该时段例如为 40ms、 80ms、 160ms, Is或其它时间长度)之 间的上下行业务量比值的变化量越大, 接入设备 300设定的第二上下行配比变 更周期 TUD越短(如不同的上下行业务量比值的变化量范围, 可对应不同大小 的第二上下行配比变更周期 TUD ), 或, 例如若小区当前激活用户数比较少(例 如 1~5个),此时该小区上下行业务突发或波动情况可能会比较频繁, 则接入设 备可以使用较小的第二上下行配比变更 TUD; 若小区当前激活用户数比较多 ( >10个), 此时多个用户的总业务量波动可能相对变緩, 则接入设备 300可以 使用较大的第二上下行配比变更 TUD, 即小区不同的当前激活用户数范围, 可 对应不同的第二上下行配比变更周期 TUD。
在一种应用场景下, 通知模块 310可具体用于, 通过系统广播消息或专用 无线资源控制信令通知用户设备第二上下行配比变更周期, 其中, 该第二上下 行配比变更周期小于系统消息变更周期。
进一步的, 接入设备 300还可根据需要选择上下行配比变更方式, 例如若 当前小区业务波动相对比较緩慢(如业务波动量小于某设定阔值 S1 ), 则接入 设备 300可选择系统消息变更周期 ^皿作为小区上下行配比变更周期 (即在每 个系统消息变更周期 TSFFIL的起始时刻可选择变更上下行配比); 若当前小区业 务波动相对较快(如业务波动量大于某设定阔值 S2 ) , 则接入设备 300可釆用动 态改变上下行配比的方式(即配置一些灵活子帧 ( flexible subframe ), 接入设 备可将每个灵活子帧动态地配置成上行子帧或下行子帧); 若当前小区业务波 动一般(如波动量介于阔值 S1和阔值 S2之间),则接入设备 300可选择小于系统 消息变更周期 TSIB1的第二上下行配比变更周期 TUD作为小区上下行配比变更周 期 (即在每个第二上下行配比变更周期 TUD的起始时刻可选择变更上下行配 比 )。例如接入设备 300可在系统广播消息中增加信息比特来指示所选择的上下 行配比变更方式; 或者, 接入设备可在专用无线资源控制(RRC )信令中增加 信息比特来指示所选择的上下行配比变更方式, 以提高配置灵活性, 可实现用 户分别配置。
配置模块 320, 用于向用户设备发送第一消息, 其中, 第一消息携带有对 应该第二上下行配比变更周期的上下行配比指示,以使得用户设备根据该上下 行配比指示更新所述用户设备使用的上下行配比。
在一种应用场景下, 配置模块 320可具体用于, 在第二上下行配比变更周 期的起始时刻, 向用户设备发送第一消息; 其中, 该第二上下行配比变更周期 的起始时刻发送的第一消息携带的上下行配比指示所指示出的上下行配比,可 在该第二上下行配比变更周期启用; 或者,在第二上下行配比变更周期的非起 始时刻, 向用户设备发送第一消息; 其中, 该第二上下行配比变更周期的非起 始时刻发送的第一消息携带的上下行配比指示所指示出的变更的上下行配比, 可在该第二上下行配比变更周期的下一个第二上下行配比变更周期启用。
在实际应用中, 配置模块 320例如可在系统广播消息 (即第一消息为系统 广播消息) 中增加对应第二上下行配比变更周期 TUD的上下行配比指示, 以通 过该系统广播消息通知用户设备当前的第二上下行配比变更周期 TUD对应的上 下行配比。 或者, 配置模块 320可在专用 RRC信令中携带对应第二上下行配比 变更周期 TUD的上下行配比指示, 以通过该专用 RRC信令(即第一消息为专用 RRC信令)通知用户设备(例如通知支持第二上下行配比变更周期 TUD的激活 态用户设备) 当前的第二上下行配比变更周期 TUD对应的上下行配比。 当然配 置模块 320也可将对应第二上下行配比变更周期 TUD的上下行配比指示携带在 其它类型的消息中发送给用户设备。
此外, 考虑到 LTE TDD系统的兼容性问题, Rel-8/9/lO的用户设备(若其 不支持第二上下行配比变更周期 TUD )仍可使用 SIB1中携带的上下行配比指示 信息来指示上下行配比,并可按照系统消息变更周期 TSffil来更新其使用的上下 行配比, 假设该配比为 "上下行配比 -1", 而处于连接态的 Rel-11用户设备或更 高版本的用户设备(若其支持第二上下行配比变更周期 TUD ),可按照设定的第 二上下行配比变更周期 TUD来更新其使用的上下行配比, H没该上下行配比为 "上下行配比 -2"; 例如图 2所示, 在同一时刻, 上下行配比 -1和上下行配比 -2 可能不同, 由于第二上下行配比 -2的变更周期 TUD小于上下行配比 -1的变更周 期 TSFFIL , 因此, 使用上下行配比 -2有利于更好地适应上下行业务快速变化的场 景; 另外, 由于上下行配比 -1可体现一段时间内的平均上下行业务量情况, 因 此, 在系统消息变更时刻若上下行配比 -1发生改变, 处于连接态的 Rel-11用户 设备可优先使用更新的上下行配比 -1。 由于空闲态 Rel-11用户设备无需发送和 接收数据, 因此, 其可使用上下行配比 -1并跟踪该上下行配比 -1的变化, 此处 由于只需要连接状态的支持灵活子帧配比的用户设备更快的更新其使用的上 下行配比, 而空闲态的 Rel-11用户设备可无需按照第二上下行配比变更周期 TUD更新其使用的上下行配比, 故而可避免寻呼空闲态用户设备所带来的系统 开销, 并有利于保证后向兼容性。
在一种应用场景下, 若第一消息为系统广播消息, 由于对应第二上下行配 比变更周期 TUD对应的上下行配比指示只用于连接态的 UE, 因此当系统广播消 息携带的对应上下行配比变更周期 TUD对应的上下行配比指示发生变化时, 接 入设备 300可不发送寻呼告知空闲态的 UE。 若第一消息为专用 RRC信令, 则若 UE在某个第二上下行配比变更周期 TUD的起始时刻接收到 RRC信令(该 RRC信 令携带对应的上下行配比变更周期 TUD的上下行配比指示 ), 则 UE可在该上下 行配比变更周期 TUD内启用该上下行配比指示所指示的上下行配比;如果 UE在 一个配比变更周期的其它位置 (即分非起始时刻 )接收到 RRC信令(该 RRC 信令携带对应的上下行配比变更周期 TUD的上下行配比指示), 则 UE可在该上 下行配比变更周期 TUD的下一个上下行配比变更周期 TUD内启用该上下行配比 指示所指示的上下行配比。 可以理解, 接入设备 300通过专用 RRC信令可以为 不同的 UE配置不同的上下行配比, 以便更好的进行上下行干扰管理, 可进一 步增加灵活性。
在实际应用中, 对应第二上下行配比变更周期 TUD的上下行配比指示可以 是能够指示出对应上下行配比的任何信息, 例如,对应第二上下行配比变更周 期 TUD的上下行配比指示可指示表 1中对应的上下行配比配置号 (表 1中的不同 配置号对应着不同的上下行配比)。 或者, 对应第二上下行配比变更周期 TUD 的上下行配比指示也可指示出一个相对偏差值,该相对偏差值为第二上下行配 值。例如, 第二上下行配比变更周期 TUD对应的上下行配比在表 1中的上下行配 比配置号为 1 ,系统消息变更周期 TSMI所对应的上下行配比在表 1中对应的上下 行配比配置号为 3 ,则对应第二上下行配比变更周期 TUD的上下行配比指示可指 示出相对偏差值为 -2 , UE通过 SIB1可获知系统消息变更周期 TSFFIL所对应的上 下行配比在表 1中对应的上下行配比配置号, 在接收到携带对应第二上下行配 比变更周期 TUD的上下行配比指示 (偏差值 -2 ) 的消息后, 可将系统消息变更 差值(-2 ), 进而获知当前第二上下行配比变更周期 TUD对应的上下行配比(上 下行配比配置号 1 )。
可以理解, 配置模块 310还可通过其它多种方式来指示第二上下行配比变 更周期 TUD对应的上下行配比, 上下行配比指示所指示的上下行配比与前一个 可以理解的是, 本实施例中的接入设备 300可如上述方法实施例中的接入 设备, 其各个功能模块的功能可以根据上述方法实施例中的方法具体实现, 其 具体实现过程可以参照上述方法实施例的相关描述, 此处不再赘述。

接收模块 420 , 用于接收来自接入设备的第一消息, 其中, 第一消息携带 有对应第二上下行配比变更周期的上下行配比指示。 配比更新模块 430 , 用于按照第一消息中携带的上下行配比指示更新其使 用的上下行配比。
在一种应用场景下, 接收模块 420具体用于, 在第二上下行配比变更周期 的起始时刻, 接收来自上述接入设备的所述第一消息; 其中, 第一消息携带的 上下行配比指示所指示出的上下行配比, 在上述第二上下行配比变更周期启 用; 或者, 在上述第二上下行配比变更周期的非起始时刻, 接收来自上述接入 设备的第一消息; 其中, 上述上下行配比指示所指示出的上下行配比, 在第二 上下行配比变更周期的下一个第二上下行配比变更周期启用。

配置更新模块 430还可用于,按照接收模块 420接收的系统消息中携带的上 下行配比指示更新用户设备 400使用的上下行配比。
在一种应用场景下, 若用户设备为支持第二上下行配比变更周期 TUD的连 接态用户设备(例如 Rel-11用户设备或更高版本的用户设备), 则其可按照第 二上下行配比变更周期 TUD和第一消息中携带的上下行配比指示来更新其使用 的上下行配比;若用户设备为可支持第二上下行配比变更周期的空闲态用户设 备(例如 Rel-11用户设备或更高版本的用户设备), 则其可按照系统消息变更 周期 TSIB1和该系统消息变更周期 TSIB1对应的上下行配比来更新其使用的上下 行配比; 若用户设备为不支持第二上下行配比变更周期的用户设备 (如 Rel-8/9/lO用户设备等), 则其可按照系统消息变更周期 TSffil和该系统消息变更 可以理解的是, 本实施例用户设备 400可如上述方法实施例中的某种用户 设备, 其各个功能模块的功能可根据上述方法实施例中的方法具体实现, 其具 体实现过程可以参照上述方法实施例的相关描述, 此处不再赘述。
