Definitions
- the present invention relates to the field of communications, and in particular to a data transmission method, apparatus, and system.
- the long-term evolution (Long-Term Evolution, LTE for short) system supports time division duplex mode (Time)
- TDD Division Duplex
- 1 is a schematic diagram of a frame structure of a TDD according to the related art.
- each radio frame is 10 ms, and is composed of 2 halves (half-frame) (ie, 5 ms per field). ), each field consists of 5 subframes (ie, each subframe is lms), and each subframe consists of 2 slots (ie, 0.5 ms per slot).
- the uplink and the downlink use the same frequency band for time-division transmission.
- the system can use part of the subframes (ie, uplink subframes) of the radio frame for uplink transmission according to a certain ratio.
- Part of the subframe (ie, the downlink subframe) is used for downlink transmission.
- choosing the appropriate uplink-downlink ratio configuration is beneficial to improve the spectrum efficiency of the TDD system. For example, for an area with a large number of downlink services, you can select a configuration with more downlink subframes. For areas with more uplink services, you can select a configuration with more uplink subframes. For areas with more balanced uplink and downlink services, You can choose a proportional configuration in which the uplink and downlink subframes are almost equal.
- the ratio of TDD uplink and downlink subframes supported by the Time Division Duplex Long-Term Evolution (TD-LTE) system is seven, as shown in Table 1.
- the subframes within a radio frame are labeled as: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
- D indicates that the sub-frame is a downlink sub-frame;
- U indicates that the sub-frame is an uplink sub-frame;
- S indicates that the sub-frame is a special sub-frame, and is used to indicate that the sub-frame before the sub-frame is a downlink sub-frame.
- the frame, the subframe after the subframe is an uplink subframe.
- the period in the table refers to the period of the special subframe. If there are special subframes in 2 fields in each radio frame, the period is 5 ms; if there is only one field in each radio frame, there is a special subframe. Then the period is 10ms.
- Table 1 Schematic diagram of the uplink and downlink configuration supported by the TD-LTE system
- the process of receiving the downlink data by the user equipment includes: the UE monitors a physical downlink control channel (Physical Downlink Control Channel, hereinafter referred to as PDCCH), and uses downlink control information (Downlink Control Information) for the UE on the PDCCH.
- PDCCH Physical Downlink Control Channel
- Downlink Control Information Downlink Control Information
- the physical downlink shared channel (PDSCH) that decodes the same subframe receives the downlink data, and feeds back the success or failure of the reception to the base station. Since the uplink and downlink subframes of different uplink and downlink configurations in the TD-LTE system are different, the timings of different configurations are different.
- the process of sending uplink data by the UE includes: the UE listening to the physical downlink control channel (Physical Downlink)
- the control channel (referred to as PDCCH) is configured to transmit uplink data on a physical uplink shared channel (PUSCH) according to downlink control information (Downlink Control Information, DCI) on the PDCCH. Since the uplink and downlink subframes of different uplink and downlink configurations in the TD-LTE system are different, the timings of different configurations are different. It is assumed that the UE receives the PDCCH in the subframe n, and transmits the PUSCH in the subframe (n+k), for different upper and lower The row configuration, the different sub-frames n, k have different values, as shown in Table 3. Table 3 Upstream timing diagram of the TD-LTE system
- the base station In the case of a bursty uplink or downlink service, if the uplink and downlink configuration cannot meet the proportional requirements of the uplink and downlink services, the base station needs to adjust the uplink and downlink configurations. At present, the base station notifies the UE of the uplink and downlink configuration changes by means of system message update. On the one hand, the system message cannot be updated frequently, and on the other hand, since the system message is not updated in real time, the base station indicates that the UE system message is updated to start using the new one.
- the line configuration requires a minimum of 640 ms, which causes a certain delay. Therefore, the data transmission method in the related art has poor performance of data transmission due to frequent uplink and downlink configuration adjustment due to burst uplink service or downlink service.
- the data transmission method in the related art informs the UE that the uplink and downlink configuration changes cannot satisfy the burst uplink service or the downlink service, and the performance of the data transmission is relatively poor, and no effective solution has been proposed yet.
- the present invention provides a data transmission method, apparatus, and system, to at least solve the above-mentioned related art data transmission method, by means of system message update, to notify the UE that the uplink and downlink configuration changes cannot meet the burst uplink service or downlink service. The problem that leads to poor performance of data transmission.

Description
数据传输方法、 装置及系统 技术领域 本发明涉及通信领域, 具体而言, 涉及一种数据传输方法、 装置及系统。 背景技术 长期演进 (Long-Term Evolution, 简称为 LTE ) 系统支持时分双工方式 (Time
Division Duplex, 简称为 TDD)。 图 1是根据相关技术的 TDD的帧结构示意图, 如图 1所示, 在时域上, 每个无线帧为 10ms, 由 2个半帧 (half-frame) 组成 (即每个半帧 为 5ms), 每个半帧由 5个子帧组成(即每个子帧为 lms), 每个子帧由 2个时隙(slot) 组成 (即每个时隙为 0.5ms)。 在频域上, 上行链路和下行链路采用相同的频带分时进 行传输, 根据业务的需要, 系统可以按照一定的比例将无线帧的部分子帧 (即上行子 帧) 用于上行传输, 部分子帧 (即下行子帧) 用于下行传输。 根据不同地区业务类型 的需要, 选择合适的上下行比例配置有利于提高 TDD系统的频谱效率。 比如, 对于下 行业务较多的地区, 就可以选择下行子帧较多的配置; 对于上行业务较多的地区, 就 可以选择上行子帧较多的配置; 对于上下行业务较平衡的地区, 就可以选择上下行子 帧差不多相等的比例配置。时分双工的长期演进系统(Time Division Duplex Long-Term Evolution, 简称为 TD-LTE)系统支持的 TDD上下行子帧的比例共 7种, 如表 1所示。 一个无线帧内的子帧分别标记为: 0, 1,2,3,4,5,6,7,8,9。 "D"表示该子帧为下行子帧; "U" 表示该子帧为上行子帧; "S"表示该子帧为特殊子帧, 用于表示在该子帧之前的子帧是 下行子帧, 在该子帧之后的子帧是上行子帧。 表中的周期指的是特殊子帧的周期, 若 每个无线帧中 2个半帧都存在特殊子帧, 则周期是 5ms; 若每个无线帧中只有 1个半 帧存在特殊子帧, 则周期是 10ms。 表 1 TD-LTE系统支持的上下行配置示意表
用户设备 (User Equipment, 简称为 UE) 接收下行数据的过程包括: UE监听物 理下行控制信道 (Physical Downlink Control Channel, 简称为 PDCCH), 根据 PDCCH 上的用于该 UE的下行控制信息 (Downlink Control Information, 简称为 DCI) 解码同 一子帧的物理下行共享信道 (Physical Downlink Shared Channel, 简称 PDSCH) 接收 下行数据, 并向基站反馈接收成功或者失败。 由于 TD-LTE系统中不同的上下行配置 的上下行子帧分布不同, 因此不同配置的时序不同, 假设 UE 在子帧 n 接收 PDCCH/PDSCH, 在子帧(n+k) 反馈接收成功或失败, 对于不同的上下行配置、 不同 的子帧 n, k的取值不同, 如表 2所示。 表 2 TD-LTE系统的下行时序示意表
UE 发送上行数据的过程包括: UE 监听物理下行控制信道 (Physical Downlink
Control Channel, 简称为 PDCCH), 根据 PDCCH上的用于所述 UE的下行控制信息 (Downlink Control Information, 简称为 DCI), 在物理上行共享信道 (Physical Uplink Shared Channel, 简称 PUSCH) 发送上行数据。 由于 TD-LTE系统中不同的上下行配 置的上下行子帧分布不同,因此不同配置的时序不同,假设 UE在子帧 n接收 PDCCH, 在子帧 (n+k) 发送 PUSCH, 对于不同的上下行配置、 不同的子帧 n, k的取值不同, 如表 3所示。 表 3 TD-LTE系统的上行时序示意表
当出现突发的上行业务或者下行业务的情况下, 如果上下行配置不能适配上下行 业务的比例需求, 基站需要调整上下行配置。 目前, 基站通过系统消息更新的方式通 知 UE上下行配置变化, 一方面由于系统消息不能频繁地更新, 另一方面由于系统消 息不是即时更新的, 从基站指示 UE系统消息更新到开始使用新的上下行配置最少需 要 640ms, 造成一定的延迟, 因此, 相关技术中的数据传输方法由于突发的上行业务 或者下行业务导致频繁上下行配置调整导致数据传输的性能比较差。 针对相关技术中的数据传输方法通过系统消息更新的方式通知 UE上下行配置变 化无法满足突发的上行业务或者下行业务, 导致数据传输的性能比较差的问题, 目前 尚未提出有效的解决方案。 发明内容 本发明提供了一种数据传输方法、 装置及系统, 以至少解决上述相关技术中的数 据传输方法通过系统消息更新的方式通知 UE上下行配置变化无法满足突发的上行业 务或者下行业务, 导致数据传输的性能比较差的问题。 根据本发明的一个方面, 提供了一种数据传输方法。 根据本发明的数据传输方法包括: 根据 TDD 系统的上行时序或下行时序在发送

( 1 ) 特定的下行子帧为子帧 0: 配置 A为以下之一: 配置 1、 配置 2、 配置 4、 配置 5 ; 配置 B为以下之一: 配置 0、 配置 3、 配置 6。 即,在上下行配置为配置 1或配置 2或配置 4或配置 5的情况下,若 UE在子帧 0 收到指示上行传输的 DCI, 则表示上下行配置调整为配置 0或配置 3或配置 6。
(2) 特定的下行子帧为子帧 1 : 配置 A为以下之一: 配置 2、 配置 3、 配置 4、 配置 5 ;
配置 B为以下之一: 配置 0、 配置 1、 配置 6。 即,在上下行配置为配置 2或配置 3或配置 4或配置 5的情况下,若 UE在子帧 1 收到指示上行传输的 DCI, 则表示上下行配置调整为配置 0或配置 1或配置 6。
(3 ) 特定的下行子帧为子帧 3 : 配置 A为: 配置 5; 配置 B为: 配置 2。 即, 在上下行配置为配置 5的情况下, 若 UE在子帧 3收到指示上行传输的 DCI, 则表示上下行配置调整为配置 2。
(4) 特定的下行子帧为子帧 4: 配置 A为以下之一: 配置 2、 配置 4、 配置 5; 配置 B为: 配置 1。 即, 在上下行配置为配置 2或配置 4或配置 5的情况下, 若 UE在子帧 4收到指 示上行传输的 DCI, 则表示上下行配置调整为配置 1。
( 5 ) 特定的下行子帧为子帧 5: 配置 A为以下之一: 配置 1、 配置 2、 配置 3、 配置 4、 配置 5; 配置 B为以下之一: 配置 0、 配置 6。 即,在上下行配置为配置 1或配置 2或配置 3或配置 4或配置 5的情况下,若 UE 在子帧 5收到指示上行传输的 DCI, 则表示上下行配置调整为配置 0或配置 6。
(6) 特定的下行子帧为子帧 6: 配置 A为以下之一: 配置 2、 配置 3、 配置 4、 配置 5; 配置 B为以下之一: 配置 0、 配置 1、 配置 6。 即,在上下行配置为配置 2或配置 3或配置 4或配置 5的情况下,若 UE在子帧 6 收到指示上行传输的 DCI, 则表示上下行配置调整为配置 0或配置 1或配置 6。
(7) 特定的下行子帧为子帧 9: 配置 A为以下之一: 配置 2、 配置 5;
配置 B为以下之一: 配置 1、 配置 3、 配置 4、 配置 6。 即, 在上下行配置为配置 2或配置 5的情况下, 若 UE在子帧 9收到指示上行传 输的 DCI, 则表示上下行配置调整为配置 1或配置 3或配置 4或配置 6。 需要说明的是, 配置 A和配置 B的一一对应关系是协议预定义的, 或者是在上下 行配置调整之前, 基站通过高层信令 (如 RRC信令) 通知 UE的。 实施例二 本实施例提供了一种数据传输方法, 本实施例结合了上述实施例及其中的优选实 施方式, 在本实施例中, 基站根据上行时序显式指示终端进行上下行配置调整。 该方 法包括如下步骤: 步骤 1 : 在上下行配置 A的情况下, 基站在特定的下行子帧发送指示上行传输的
DCI给 UE, 其中, 该 DCI携带指示上下行配置调整的字段。 步骤 2: UE收到 DCI调整上下行配置为配置8。 需要说明的是,不同上下行配置的上行时序不同, UE在下行子帧收到指示上行传 输的 DCI, 在不同的上下行配置的情况下指的是在不同的上行子帧发送上行数据。 需要说明的是, 由于不同上下行配置的上行时序不同, UE在下行子帧收到指示上 行传输的 DCI,在不同的上下行配置的情况下指的是在不同的上行子帧发送上行数据。 如表 3所示, 在同一个下行子帧中, 在多种配置的情况下基站可以为 UE分配上 行授权, 根据上述指示上下行配置调整的字段的取值不同和 /或调整原则不同, UE可 知调整后的上下行配置。 优选的, 该方法包括以下方式: ( 1 ) 在上述特定的下行子帧, 配置 B是唯一的上行时序与配置 A的上行时序相 同的上下行配置。 优选地, 配置 A、 特定的下行子帧、 配置 B的关系如下: 在特定下行子帧为子帧
0时, 在子帧 0上发送携带有用于指示上下行配置调整的字段的指示上行传输的 DCI, 用于直接指示终端将上下行配置从第一配置转换为二配置, 其中, 第一配置为: 配置 0, 第二配置为: 配置 3 ; 在特定下行子帧为子帧 0时, 在子帧 0发送携带有用于指示 上下行配置调整的字段的指示上行传输的 DCI, 用于直接指示终端将上下行配置从第 一配置转换为二配置, 其中, 第一配置为: 配置 3, 第二配置为: 配置 0; 在特定下行 子帧为子帧 1或子帧 6时, 在子帧 0或子帧 6上发送携带有用于指示上下行配置调整
的字段的指示上行传输的 DCI, 用于直接指示终端将上下行配置从第一配置转换为二 配置, 其中, 第一配置为: 配置 0, 第二配置为: 配置 1 ; 在特定下行子帧为子帧 1 或子帧 6时, 在子帧 0或子帧 6上发送携带有用于指示上下行配置调整的字段的指示 上行传输的 DCI, 用于直接指示终端将上下行配置从第一配置转换为二配置, 其中, 第一配置为: 配置 1, 第二配置为: 配置 0。 上述对应关系如下表 4所示: 表 4上下行配置调整规则示意表一
采用 Cx表示配置 B是配置 x, 例如: C3表示配置 B是配置 3。 此外, 阴影部分 表示是上行子帧。 具体地, 以表 3所示的子帧 0为例,只有配置 0、配置 3、配置 6存在上行时序(即 基站可以在子帧 0分配上行授权),其中只有配置 3和配置 0的上行时序一致(即基站 在子帧 0分配的上行授权指示 UE在同一个上行子帧 (即子帧 4) 发送上行数据), 因 此在上下行配置是配置 0的情况下, 基站在子帧 0发送指示上行传输的 DCI给 UE, 其中, 该 DCI携带指示上下行配置调整的字段, 无论该字段的取值如何, 只要依据调 整后的上行时序不变, 则 UE可知调整后的上下行配置是配置 3。
(2) 在特定的下行子帧, 配置 B是唯一的上行时序与配置 A的上行时序不同的 上下行配置。 优选地, 配置 A (第一配置)、 特定的下行子帧、 配置 B (第二配置) 的对应关系 如下所示: 在特定的下行子帧为子帧 0时, 在子帧 0上发送携带有用于指示上下行配 置调整的字段的指示上行传输的 DCI用于直接指示终端将上下行配置从第一配置转换 为二配置, 其中, 第一配置为以下之一: 配置 0、 配置 3, 第二配置为: 配置 6; 在特 定的下行子帧为子帧 1或子帧 6时, 在子帧 0或子帧 6上发送携带有用于指示上下行 配置调整的字段的指示上行传输的 DCI用于直接指示终端将上下行配置从第一配置转 换为二配置, 其中, 第一配置为: 配置 0、 配置 1, 第二配置为: 配置 6; 在特定的下
行子帧为子帧 5时, 在子帧 5上发送携带有用于指示上下行配置调整的字段的指示上 行传输的 DCI用于直接指示终端将上下行配置从第一配置转换为二配置, 其中, 第一 配置为: 配置 0, 第二配置为: 配置 6; 在特定的下行子帧为子帧 5时, 在子帧 5上发 送携带有用于指示上下行配置调整的字段的指示上行传输的 DCI用于直接指示终端将 上下行配置从第一配置转换为二配置, 其中, 第一配置为: 配置 6, 第二配置为: 配 置 0; 在特定的下行子帧为子帧 9时, 在子帧 9上发送携带有用于指示上下行配置调 整的字段的指示上行传输的 DCI用于直接指示终端将上下行配置从第一配置转换为二 配置, 其中, 第一配置为以下之一: 配置 1、 配置 3、 配置 4, 第二配置为: 配置 6。 上述对应关系如下表 5所示: 表 5 上下行配置调整规则示意表二
具体地,以表 3所示的子帧 0为例,只有配置 0、配置 3、配置 6存在上行时序(即 基站可以在子帧 0分配上行授权),其中只有配置 6和配置 0的上行时序不同(即基站 在子帧 0分配的上行授权指示 UE在不同的上行子帧(即配置 0在子帧 4,配置 6在子 帧 7)发送上行数据), 因此在上下行配置是配置 0的情况下, 基站在子帧 0发送指示 上行传输的 DCI给 UE, 其中, 该 DCI携带指示上下行配置调整的字段, 无论该字段 的取值如何, 只要依据调整后的上行时序变化, 则 UE可知调整后的上下行配置是配 置 6。
(3 )在特定的下行子帧, 配置 B是唯一的上行时序与所有上下行配置的上行时 序都不同的上下行配置。 优选地, 配置 A (第一配置)、 特定的下行子帧、 配置 B (第二配置) 的对应关系 如下表 6所示: 在特定的下行子帧为子帧 0时, 在子帧 0上发送携带有用于指示上下 行配置调整的字段的指示上行传输的 DCI用于直接指示终端将上下行配置从第一配置 转换为二配置, 其中, 第一配置为以下之一: 配置 0、 配置 3, 第二配置为: 配置 6; 在特定的下行子帧为子帧 1或子帧 6时, 在子帧 0或子帧 6上发送携带有用于指示上
下行配置调整的字段的指示上行传输的 DCI用于直接指示终端将上下行配置从第一配 置转换为二配置, 其中, 第一配置为: 配置 0、 配置 1, 第二配置为: 配置 6; 在特定 的下行子帧为子帧 5时, 在子帧 5上发送携带有用于指示上下行配置调整的字段的指 示上行传输的 DCI用于直接指示终端将上下行配置从第一配置转换为二配置, 其中, 第一配置为: 配置 0, 第二配置为: 配置 6; 在特定的下行子帧为子帧 5时, 在子帧 5 上发送携带有用于指示上下行配置调整的字段的指示上行传输的 DCI用于直接指示终 端将上下行配置从第一配置转换为二配置, 其中, 第一配置为: 配置 6, 第二配置为: 配置 0; 在特定的下行子帧为子帧 9时, 在子帧 9上发送携带有用于指示上下行配置 调整的字段的指示上行传输的 DCI用于直接指示终端将上下行配置从第一配置转换为 二配置, 其中, 第一配置为以下之一: 配置 1、 配置 3、 配置 4, 第二配置为: 配置 6。 上述对应关系如下表 6所示: 表 6上下行配置调整规则示意表三
具体地,以表 3所示的子帧 0为例,只有配置 0、配置 3、配置 6存在上行时序(即 基站可以在子帧 0分配上行授权),其中只有配置 6的上行时序是唯一的(即基站在子 帧 0分配的上行授权指示 UE在不同的上行子帧(即配置 0、 配置 3都在子帧 4, 配置 6在子帧 7) 发送上行数据), 因此在上下行配置是配置 0或配置 3的情况下, 基站在 子帧 0发送指示上行传输的 DCI给 UE, 其中, 该 DCI携带指示上下行配置调整的字 段, 无论上述字段的取值如何, 只要依据调整后的上行时序唯一, 则 UE可知调整后 的上下行配置是配置 6。 由此可得 [原则 3]: 在上述特定的下行子帧, 配置 B是唯一的 上行时序与所有上下行配置的上行时序都不同的上下行配置。
(4)在该特定的下行子帧, 同时满足: 配置 B和除配置 A、配置 B之外的另一上下行配置的配置 C在上述特定的下行子 帧的上行时序相同;
配置 B (或配置 C) 和除配置 、 配置 B、 配置 C之外的其他上下行配置在上述 特定的下行子帧的上行时序不同; 配置 B (或配置 C) 和配置 A在上述特定的下行子帧的上行时序相同或者不同。 优选地, 特定的下行子帧为子帧 0、配置 A为配置 6的情况下, UE根据上述指示 上下行配置调整的字段的取值可知配置 B是配置 0或者配置 3。 特定的下行子帧为子帧 1或子帧 6、配置 A为配置 6的情况下, UE根据上述指示 上下行配置调整的字段的取值可知配置 B是配置 0或者配置 1。 具体地, 以表 3所示的子帧 0为例,只有配置 0、配置 3、配置 6存在上行时序(即 基站可以在子帧 0分配上行授权),其中配置 3和配置 0的上行时序一致(即基站在子 帧 0分配的上行授权指示 UE在同一个上行子帧(即子帧 4)发送上行数据), 配置 0、 配置 3的上行时序与配置 6的上行时序不同, 因此在上下行配置是配置 6的情况下, 基站在子帧 0发送指示上行传输的 DCI给 UE, 其中, 该 DCI携带指示上下行配置调 整的字段,根据字段的取值不同,则 UE可知调整后的上下行配置是配置 0或者配置 3。 优选地, 在不同的下行子帧采用的调整原则是相同或者不同的。 优选地, 在不同的上下行配置采用的调整原则是相同或者不同的。 优选地, 该调整原则是协议预定义的, 或者是在上下行配置调整之前, 基站通过 高层信令 (如 RRC信令) 通知 UE的。 实施例三 本实施例提供了一种数据传输方法, 本实施例结合了上述实施例及其中的优选实 施方式, 在本实施例中, 基站根据下行时序显式指示终端进行上下行配置调整。 该方 法包括如下步骤: 步骤 1 : 在上下行配置 A的情况下, 基站在特定的下行子帧发送指示下行传输的 DCI给 UE, 其中, 该 DCI携带指示上下行配置调整的字段。 步骤 2: UE收到 DCI调整上下行配置为配置8。 需要说明的是, 由于不同上下行配置的下行时序不同, UE在下行子帧收到下行数 据, 在不同的上下行配置的情况下指的是在不同的上行子帧发送反馈信息指示上述下 行数据是否接收成功。
如表 2所示, 在同一个下行子帧中, 在多种配置的情况下基站可以为 UE分配下 行指配, 根据上述指示上下行配置调整的字段的取值不同和 /或调整原则不同, UE可 知调整后的上下行配置。 优选地, 包括以下方式:
( 1 )在特定的下行子帧, 配置 B是唯一的下行时序与配置 A的下行时序相同的 上下行配置。 例如: 在子帧 0, 配置 3是唯一与配置 0的下行时序相同的上下行配置 (即都是 在子帧 4反馈子帧 0上的下行传输),因此当上下行配置为配置 0的 UE在子帧 0收到 指示下行传输的 DCI, 并且上述 DCI中携带指示上下行配置调整的字段, 则 UE将上 下行配置调整为配置 3。 优选地, 配置 A (第一配置)、 特定的下行子帧、 配置 B (第二配置) 的对应关系 如下表 7所示: 在特定的下行子帧为子帧 0时, 在子帧 0上发送携带有用于指示上下 行配置调整的字段的指示上行传输的 DCI用于直接指示终端将上下行配置从第一配置 转换为二配置, 其中, 第一配置为配置 0, 第二配置为: 配置 3 ; 在特定的下行子帧为 子帧 0时, 在子帧 0上发送携带有用于指示上下行配置调整的字段的指示上行传输的 DCI用于直接指示终端将上下行配置从第一配置转换为二配置, 其中, 第一配置为配 置 3, 第二配置为: 配置 0; 在特定的下行子帧为子帧 0时, 在子帧 0上发送携带有用 于指示上下行配置调整的字段的指示上行传输的 DCI用于直接指示终端将上下行配置 从第一配置转换为二配置, 其中, 第一配置为配置 4, 第二配置为: 配置 5; 在特定的 下行子帧为子帧 0时, 在子帧 0上发送携带有用于指示上下行配置调整的字段的指示 上行传输的 DCI用于直接指示终端将上下行配置从第一配置转换为二配置, 其中, 第 一配置为配置 5, 第二配置为: 配置 4; 在特定的下行子帧为子帧 6时, 在子帧 6上发 送携带有用于指示上下行配置调整的字段的指示上行传输的 DCI用于直接指示终端将 上下行配置从第一配置转换为二配置, 其中, 第一配置为: 配置 4, 第二配置为: 配 置 6; 在特定的下行子帧为子帧 6时, 在子帧 6上发送携带有用于指示上下行配置调 整的字段的指示上行传输的 DCI用于直接指示终端将上下行配置从第一配置转换为二 配置, 其中, 第一配置为: 配置 6, 第二配置为: 配置 4; 在特定的下行子帧为子帧 7 时, 在子帧 7上发送携带有用于指示上下行配置调整的字段的指示上行传输的 DCI用 于直接指示终端将上下行配置从第一配置转换为二配置, 其中, 第一配置为: 配置 3, 第二配置为: 配置 4; 在特定的下行子帧为子帧 7时, 在子帧 7上发送携带有用于指 示上下行配置调整的字段的指示上行传输的 DCI用于直接指示终端将上下行配置从第 一配置转换为二配置, 其中, 第一配置为: 配置 4, 第二配置为: 配置 3 ; 在特定的下 行子帧为子帧 8时, 在子帧 8上发送携带有用于指示上下行配置调整的字段的指示上

例如: 在子帧 1, 只有配置 6的下行时序是唯一的 (即只有配置 6在子帧 8反馈 子帧 1上的下行传输), 因此当上下行配置为配置 0、配置 1、配置 2、配置 3、配置 4、 配置 5之一的 UE在子帧 1收到指示下行传输的 DCI, 并且上述 DCI中携带指示上下 行配置调整的字段, 则 UE将上下行配置调整为配置 6。 优选地, 配置 A (第一配置)、 特定的下行子帧、 配置 B (第二配置) 的对应关系 如下: 在第三预定下行子帧为子帧 1时, 在子帧 3上发送携带有用于指示上下行配置 调整的字段的指示上行传输的 DCI用于直接指示终端将上下行配置从第一配置转换为 二配置, 其中, 第一配置为以下之一: 配置 0、 配置 1、 配置 2配置 3、 配置 4、 配置 5, 第二配置为: 配置 6; 在特定的下行子帧为子帧 3时, 在子帧 3上发送携带有用于 指示上下行配置调整的字段的指示上行传输的 DCI用于直接指示终端将上下行配置从 第一配置转换为二配置, 其中, 第一配置为配置 2, 第二配置为: 配置 5 ; 在特定的下 行子帧为子帧 3时, 在子帧 3上发送携带有用于指示上下行配置调整的字段的指示上 行传输的 DCI用于直接指示终端将上下行配置从第一配置转换为二配置, 其中, 第一 配置为配置 5, 第二配置为: 配置 2; 在特定的下行子帧为子帧 4时, 在子帧 3上发送 携带有用于指示上下行配置调整的字段的指示上行传输的 DCI用于直接指示终端将上 下行配置从第一配置转换为二配置, 其中, 第一配置为以下之一: 配置 2、 配置 4、 配 置 5, 第二配置为: 配置 1 ; 在特定的下行子帧为子帧 5时, 在子帧 3上发送携带有用 于指示上下行配置调整的字段的指示上行传输的 DCI用于直接指示终端将上下行配置 从第一配置转换为二配置, 其中, 第一配置为以下之一: 配置 1、 配置 2配置 3、 配置 4、 配置 5, 配置 6, 第二配置为: 配置 0; 在特定的下行子帧为子帧 7时, 在子帧 3 上发送携带有用于指示上下行配置调整的字段的指示上行传输的 DCI用于直接指示终 端将上下行配置从第一配置转换为二配置, 其中, 第一配置为以下之一: 配置 3、 配 置 4, 配置 6, 第二配置为: 配置 5。 上述对应关系如下表 9所示: 表 9上下行配置调整规则示意表六
