技术领域 FIELD

[0001 ] 本发明设及通信领域,尤其设及一种时分双工(T孤,Time Division Duplex)系统中的数据传输的方法和设备。 [0001] The present invention is provided and the field of communications, and in particular is provided a time division duplex (T solitary, Time Division Duplex) system, data transmission method and apparatus.

背景技术 Background technique

[0002] 长期演进化TE ,Long-Term Evolution)系统支持T孤方式,如图1所示,在时域上, 每个无线帖为10ms,由2个半帖化alf-打ame)组成(即每个半帖为5ms),每个半帖由5个子帖组成(即每个子帖为1ms),每个子帖由2个时隙(slot)组成(即每个时隙为0.5ms)。 [0002] Long Term Evolution of TE, Long-Term Evolution) system supports T solitary embodiment, shown in Figure 1, in the time domain, to each radio posts 10ms, the two half-posts of alf- play AME) Composition ( i.e. each half note is 5ms), each half consists of five sub posts posts composition (i.e., each sub-signature is 1ms), each sub-note from the two slots (slot) composition (i.e., each time slot is 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W按照一定的比例将无线帖的部分子帖(即上行子帖)用于上行传输,部分子帖(即下行子帖)用于下行传输。 In the frequency domain, the uplink and downlink time division using the same frequency band for transmission, according to the service needs of the system according to certain proportion W may be part of the radio sub-posts posts (i.e. uplink sub-signatures) for uplink transmission , the sub-part posts (i.e. a downlink sub-signatures) for downlink transmission. 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TOD系统的频谱效率。 According to the type of business needs in different areas, select the appropriate uplink and downlink ratio configuration TOD will help improve the spectral efficiency of the system. 比如,对于下行业务较多的地区,可选择下行子帖较多的配置;对于上行业务较多的地区,可选择上行子帖较多的配置;对于上下行业务较平衡的地区,可选择上下行子帖差不多相等的比例配置。 For example, for more downlink service area, select a downlink sub-posts arranged more; for more uplink service areas, select an uplink sub-posts arranged more; for the uplink and downlink service area a more balanced, alternatively down rows of sub-post almost equal proportions configuration. LTE TDD(或称为TD-LTE)系统支持的TDD上下行子帖的比例共有7 种,如下表1所示: The proportion of the LTE TDD (or referred to as TD-LTE) system supports a TDD uplink and downlink sub total of seven kinds of posts, as shown in Table 1:

"护表示该子帖为下行子帖;"U"表示该子帖为上行子帖;"S"表示该子帖为特殊子帖,用于表示在该子帖之前的子帖是下行子帖,在该子帖之后的子帖是上行子帖。表1中的周期指的是特殊子帖的周期,若每个无线帖中2个半帖都存在特殊子帖,则周期是5ms;若每个无线帖中只有1个半帖存在特殊子帖,则周期是1 Oms。 "Indicates that the guard sub post downlink sub post;" the U-"indicates that the sub-signatures for the uplink sub-post;" S "indicates that the sub-signatures for the special sub-signatures for indicating the sub-sub-signatures before the signatures are downlink sub posts , after the sub-sub-posts posts posts uplink sub-period in table 1 refers to a period of a special sub-posts, if posts in each radio there are two special sub-half-posts posts, then the period is 5ms;. if each wireless quote only a half note there is a special sub-signature, then the period is 1 Oms.

[0006] 由于TD-LTE系统中不同的上下行配置的上下行子帖分布不同,因此不同配置的时序也就不同。 [0006] Since the distribution of the different uplink and downlink sub-signatures TD-LTE system configured in different uplink and downlink, and therefore the timing is different in different configurations. 表2所示是TD-LTE系统的下行时序,用户设备(肥,User Equipment)在上行子帖n反馈在下行子帖(n-kpDSCH)接收到的下行数据是否接收成功。 Table 2 shows downlink timing TD-LTE system, the user equipment (fertilizer, User Equipment) in uplink subframe n posts downlink sub feedback tie (n-kpDSCH) whether the received downlink data received successfully. 其中,kpDSCH表示下行数据传输的子帖与上行反馈的子帖之间的时间间隔。 Wherein, kpDSCH represents the time interval between the sub-sub-posts posts downlink data transmission and an uplink feedback.

[0012]在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。 [0012] In the case of a sudden uplink traffic or downlink traffic, if the uplink and downlink proportional configuration is not adapted to the needs of the uplink and downlink service, the base station needs to adjust the downlink configuration. 为了灵活地调整上下行配置,现有技术引入动态子帖的概念,动态子帖指的是根据基站的调度灵活调整是下行子帖或者上行子帖。 In order to flexibly adjust the uplink and downlink configurations, the prior art introduces the concept of dynamic sub-posts, posts refers dynamic sub flexibly adjusted according to the scheduling base station is a downlink or uplink sub-sub-posts posts. 对于5ms周期的上下行配置,子帖0、1、5、6是下行子帖(需要说明的是,此处将特殊子帖归为下行子帖是因为在上述时序中特殊子帖作为下行子帖处理),子帖2、7是上行子帖,子帖3、4、8、9 是动态子帖。 For 5ms downlink configuration period, sub-note is a downlink sub-0,1,5,6 posts (Incidentally, here the special downlink sub-sub-classified as posts posts posts because as a special sub-sequence in the downlink subframe in the above post treatment), 2,7 uplink sub-sub-posts posts, dynamic sub-sub-3,4,8,9 posts posts. 对于IOms周期的上下行配置,子帖0、1、5、6、7、8、9是下行子帖,子帖2是上行子帖,子帖3、4是动态子帖。 For IOms downlink configuration period, the sub-sub-posts posts 0,1,5,6,7,8,9 downlink, uplink sub-sub-posts posts 2, 3 and 4 is a dynamic sub-sub-posts posts.

[001引在5ms周期的上下行配置中,当动态子帖巧帖3、4、8、9)依次为"UUUlf,表示是配置0;当动态子帖依次为"UU邮',表示是配置6;当动态子帖依次为"UD邮',表示是配置1;当动态子帖依次为"孤D护,表示是配置2。 [001 incorporated in the uplink and downlink configuration 5ms cycle, when the dynamic signature sub coincidence posts 3,4,8,9) followed by "UUUlf, is arranged represents 0; when the dynamic order of the sub-post" UU-mail ', represents a configuration 6; when the dynamic order of the sub-post "Post the UD 'is arranged represents 1; when the dynamic order of the sub-posts" lone guard D, 2 represents a configuration. 在IOms周期的上下行配置中,当动态子帖(子帖3、4) 依次为"UU",表示是配置3;当动态子帖依次为"UD",表示是配置4;当动态子帖依次为"D护, 表示是配置5。由此可见,调整动态子帖(即动态子帖由上行子帖变为下行子帖,或者由下行子帖变为上行子帖)实际上就是调整上下行配置。 In the uplink and downlink configuration IOms cycle, when the dynamic sub-posts (posts sub 3,4) were "UU", 3 denotes a configuration; when the dynamic order of the sub-post "UD", 4 denotes a configuration; when the dynamic child posts followed by "D care, it represents the configuration is 5. Thus, the dynamic adjustment of the sub-signatures (i.e., dynamic sub-sub-note from the note becomes uplink downlink sub posts, posts or the downlink sub-signatures becomes uplink sub) is actually adjusted vertically line configuration.

[0014] 由于不同的上下行配置的时序不同,因此在调整动态子帖时会导致数据传输失败。 [0014] Since different timings different uplink and downlink configurations, so when adjusting the dynamic sub-signature will cause the data transmission fails. 例如,在5ms的上下行配置中,动态子帖9由上行子帖调整为下行子帖,其余动态子帖(子帖3、4、8)保持为上行子帖,如图2所示,无线帖n是配置0,无线帖(n+1)是配置6。 For example, in the uplink and downlink configuration 5ms, the dynamic sub-posts 9 the uplink sub-adjusted downlink sub posts posts, posts remaining dynamic sub (sub posts 3,4,8) maintained uplink sub-posts, shown in Figure 2, the radio n is 0 posts configuration, radio posts (n + 1) 6 are arranged. 基站在无线帖n的子帖6发送下行数据给UE,肥按照配置0的下行时序,在无线帖(n+1)的子帖2反馈所述下行数据是否接收成功。 The radio base station of the posts 6 posts n send downlink data to the UE, according to the configuration 0 fertilizer downlink timing in the radio posts (n + 1) of the second feedback tie whether the downlink data successfully received. 而在无线帖(n+1),动态子帖已调整,意味着上下行配置调整,按照调整后的配置6的下行时序,基站在无线帖(n+1)的子帖2收到的反馈信息认为是对无线帖n 的子帖5的下行数据的反馈。 In the wireless posts (n + 1), the dynamic sub posts adjusted, the adjustment means vertically arranged rows, arranged according to the adjusted downlink timing 6, the base station 2 receives the feedback tie in the radio posts (n + 1) is sub feedback information that is n posts downlink data radio posts 5. 由于基站无法正常获得所述在无线帖n的子帖6发送的下行数据的反馈信息,将导致不必要的数据重传(基站误认为所述数据传输失败)或者数据丢失(基站误认为所述数据传输成功)。 Since the base station can not be obtained in the normal signature feedback information of downlink data transmitted in the radio 6 posts n will result in unnecessary retransmission of data (the data transmission base station mistaken failure), or loss of data (the base station mistaken data transfer is successful). 由此,如何保证在上下行配置调整过程中,数据传输不会因为上下行配置调整而中断或传输失败,是目前亟待解决的问题。 Thus, how to ensure that the adjustment process in the uplink and downlink configuration, the data transmission will not be interrupted uplink and downlink configuration adjustments or transmission failure, is a serious problem.
