Description

一种TDD系统载波聚合的上下行配置和接收方法 Carrier aggregation in a TDD system and method for receiving downlink configuration

技术领域 FIELD

[0001] 本发明涉及载波聚合技术,特别涉及一种时分复用(TDD)系统载波聚合的上下行配置和接收方法。 [0001] The present invention relates to carrier aggregation technology, particularly to a time division multiplexing (TDD) method system carrier aggregation and receive uplink and downlink configurations.

背景技术 Background technique

[0002] LTE-Advanced(简称LTE-A)系统能够支持比长期演进(LTE)系统更宽的系统带宽,比如100MHz。 [0002] LTE-Advanced (abbreviated LTE-A) system to support wider than the long term evolution (LTE) system, the system bandwidth, such as 100MHz. 具体地,可以通过将多个LTE载波(又称成员载波)的资源连接起来使用,以为LTE-A UE提供更宽的系统带宽,其中,LTE-A UE是LTE演进系统的终端设备,能够在LTE-A系统中工作,并能支持LTE-A系统所提供的新功能。 Specifically, by connecting a plurality of LTE carriers (also called carriers) use up resources, LTE-A UE that provide a wider system bandwidth, wherein, LTE-A UE is a terminal equipment LTE evolved system, it is possible LTE-a system to work, and can support the new features LTE-a system is provided. 具体LTE-A系统有两种连接多个LTE载波资源的方式,一种是将多个连续的LTE载波进行聚合,另一种是将多个不连续的LTE载波进行聚合,均可以为LTE-A提供更大的传输带宽。 DETAILED LTE-A system, there are two ways of connecting a plurality of resources LTE carrier A is an LTE carriers plurality of continuous polymerization, the other is a plurality of discrete polymeric LTE carriers, that may LTE- a provides greater transmission bandwidth. 图1给出了不连续载波聚合的例子。 Figure 1 shows an example of discontinuous carrier aggregation.

[0003] 目前标准化组织的研究倾向为,对于载波聚合系统设计的共识是,载波上的设计保持与LTE Releases (简称R8)尽量一致,从而不仅能够为LTE-A终端提供更大的传输带宽,同时还能够保证LTE R8的终端(简称LTE UE)在每一个成员载波上正常工作,以实现向下兼容。 [0003] It is Inclination standardization organizations for a carrier aggregation system design consensus is kept as a carrier design is consistent with LTE Releases (referred to R8), so that not only to provide greater bandwidth for the LTE-A terminal, It also ensures a terminal LTE R8 (the LTE UE) work on each component carrier, so as to achieve backward compatibility.

[0004] 对LTE Release 8 TDD模式来讲,通过不同的上下行配置来满足上下行不对称业务量的需求,其上下行子帧分配有表1所示的多种配置。 [0004] The LTE Release 8 TDD mode is concerned, to meet asymmetric uplink and downlink traffic demands through different uplink and downlink configurations which have uplink and downlink sub-frame allocation shown in Table 1 a variety of configurations. 在TDD系统中,基站需要向小区广播本小区当前的上下行子帧分配信息,TDD终端获得此信息后才能进行正常的数据发送和接收。 In a TDD system, the base station needs a cell broadcast frame allocation information to present a current uplink and downlink sub cell can transmit and receive data normally after the TDD terminal to obtain this information.

[0005] 而目前LTE-A系统设计中未考虑TDD模式下不同载波上的上下行配置问题,没有相关的解决方案,也无法保证R8的终端在每一个成员载波上正常工作。 [0005] LTE-A system and the current design is not considered in the uplink and downlink TDD mode different carrier configuration issues, no solutions can not guarantee R8 terminal work on each component carrier.

具体实施方式 Detailed ways

[0040] 为使本发明的目的、技术手段和优点更加清楚明白,以下结合附图对本发明做进一步详细说明。 [0040] To make the objectives, technical means and advantages of the present invention will become apparent from the following description in conjunction with the accompanying drawings in further detail of the present invention.

[0041] 图2为本发明提供的TDD系统载波聚合的上下行配置方法总体流程图。 General flow diagram [0041] FIG. 2 uplink carrier aggregation TDD system configuration method of the present disclosure. 如图2所示,该方法包括: 2, the method comprising:

[0042] 步骤201,为小区内参与聚合的各个成员载波独立进行上下行配置,并保证至少两个成员载波间存在至少一个相同的上行子帧和至少一个相同的下行子帧,至少一个成员载波的配置符合R8的上下行配置。 [0042] Step 201, the cell is involved in the polymerization of the respective uplink and downlink carrier independently arranged, and to ensure that there is at least a same uplink subframe and at least one same downlink sub-frame members between at least two carriers, at least one carrier R8 configuration in line with uplink and downlink configurations.

[0043] 本发明提出对于LTE-A TDD系统,其每个成员载波上的上下行配置可独立配置,即可以出现如下种情况:各个成员载波上的上下行配置完全相同,或者,各个成员载波上的上下行配置不同。 [0043] The present invention provides for the LTE-A TDD system, uplink and downlink configuration on each carrier independently configurable, i.e. following cases can occur: on each downlink carrier members are configured identically, or, each carrier on different uplink and downlink configurations.

[0044] 优选地,由于成员载波上可能有其他邻频的TDD系统,为符合邻频载波间的要求, 保证各个系统的正常运行,要求在成员载波的上下行配置过程中,每个成员载波的上下行配置与其邻频的上下行配置满足共存要求,即对该载波的上下行分配有一定的限制。 [0044] Preferably, since there may be other members of the adjacent channel carrier TDD system, to meet the requirements between the adjacent carriers, ensure the normal operation of each system, the uplink and downlink configuration process requires carriers, each carrier Adjacent its upper and lower row of vertically arranged rows arranged to meet coexistence requirements, i.e. certain restrictions assigned to the uplink and downlink carriers. 具体的共存要求和对上下行配置的限制与现有的要求相同。 Specific coexistence requirements and limitations with the existing requirements for the same uplink and downlink configuration. 例如图3和图4描述。 FIGS. 3 and described in example 4.

[0045] 如图3所示,由于运营商在频点fl上部署了TD-CDMA网络(例如上下行配置为7:8),同时在与fl相邻的频点f2上部署了LTE-TDD系统1,由于邻频共存的需要,该LTE-TDD系统1的上下行配置需按照表1中的配置6进行配置,以避免邻频系统间干扰; [0045] 3, as operators TD-CDMA networks deployed at the frequency fl (e.g. vertically arranged rows 7: 8), the LTE-TDD deployed on neighboring frequency fl and f2 the system, due to the need of the adjacent frequency coexistence, the LTE-TDD uplink and downlink configurations 1 need to be arranged according to configuration 6 in table 1, in order to avoid inter-system adjacent channel interference;

[0046] 如图4所示,由于频点f3上部署了TD-SCDMA(例如上下行配置为4 :3),同时在与f3相邻的频点f4上部署了LTE-TDD系统2,由于邻频共存的需要,该LTE-TDD系统2的上下行配置需按照表1中的配置1进行配置,以避免邻频系统间干扰。 [0046] As shown, since the deployment of the TD-SCDMA on the frequency f3 (e.g. uplink and downlink configurations as 4: 3) 4, and LTE-TDD systems are deployed on adjacent frequencies f3 and f4 2, since required adjacent channel coexistence of the LTE-TDD uplink and downlink configuration 2 in table 1 need to be arranged in a configuration to avoid interference between adjacent frequency system.

[0047] 同时,为保证LTE-A系统能够为LTE-A UE提供更高的系统带宽,要求能够同时将多个载波分配给同一LTE-A UE使用,并且这多个载波需要具有相同的上行或下行子帧,因此,在进行上下行时隙配置时,需要至少两个成员载波间存在至少一个相同的上行子帧和至少一个相同的下行子帧,以为LTE-A UE提供足够的带宽进行数据传输。 [0047] Meanwhile, to ensure LTE-A system can provide higher bandwidth systems LTE-A UE, capable of simultaneously requires a plurality of carriers allocated to the LTE-A UE using the same, and the plurality of uplink carriers need to have the same or downlink sub-frame, therefore, when performing uplink-downlink configuration, at least between the at least two carriers one and the same uplink subframe and at least one and the same downlink subframe exists, LTE-a UE that provides sufficient bandwidth data transmission.

[0048] 进一步地,为保证成员载波能够向下兼容R8,要求至少一个成员载波的配置符合R8的上下行配置。 [0048] Further, in order to ensure backward compatible carrier R8, it requires at least one carrier member arranged vertically in line with the rows arranged R8.

[0049] 上述即为在成员载波进行上下行配置时需要满足的条件。 [0049] The above-described conditions shall be satisfied needs in uplink and downlink configurations carrier. 具体的,在成员载波上下行配置过程中,优选地,可以按照下述方式进行: Specifically, in the uplink component carrier configuration, preferably, may be performed in the following manner:

[0050] 判断小区内的载波聚合方式为连续聚合还是非连续聚合,若是连续聚合,则为所有成员载波进行相同的上下行配置,若是非连续聚合,则为每个成员载波分别进行上下行配置。 [0050] Carrier aggregation is determined in the cell as a non-continuous polymerization or continuous polymerization, continuous polymerization if, for the same carrier for all members of the uplink and downlink configuration, if the non-continuous polymerization was carried out for each carrier are vertically arranged rows .

[0051] 具体的,当多个成员载波是连续聚合的情况,由于各个载波邻频,配置互不相同的上下行分配会导致相邻频带上上下行之间的互干扰,因此优选地配置成各个载波的上下行配置相同。 [0051] Specifically, a plurality of component carriers when a continuous polymerization is the case, since the respective adjacent channel carrier, arranged mutually different uplink and downlink allocation cause mutual interference between adjacent band uplink and downlink, and therefore preferably configured each of uplink and downlink carriers is configured the same. 当然,也可以不同的上下行配置,这时,需要考虑邻频的干扰问题。 Of course, you can also configure different uplink and downlink, then, to consider adjacent channel interference problems.

[0052] 当多个成员载波是非连续聚合的情况,由于各个载波之间在频谱上互不相邻,因此可以配置成不同的上下行配置,而不会存在前述的干扰问题。 [0052] When a plurality of non-continuous polymeric carriers, since the carriers between the respective adjacent to each other on the spectrum, it can be configured to different uplink and downlink configurations, without the presence of interference. 但是,各个成员载波与其邻频载波间的上下行配置仍需要符合前述的共存要求。 However, the uplink and downlink configuration between the various members of the carrier and its adjacent frequency carriers still need to comply with the aforementioned coexistence requirements.

[0053] 经过上述配置的各个成员载波,可以全部成员载波均符合R8的上下行配置,也可以其中的部分成员载波符合R8的上下行配置,具体每个载波的所选择的上下行配置也可以是任意选择进行组合的,只要满足前述的邻频间共存要求等限制条件即可。 [0053] After the above each component carrier configuration may all carriers are in line vertically arranged rows of R8, which may be part of the carrier member is disposed in line with the vertical row R8, specific configuration of the selected uplink and downlink for each carrier may be the combination is arbitrarily selected, as long as the inter-adjacent frequency coexistence requirements, etc. to restrictions.

[0054] 步骤202,将每个成员载波的上下行配置和与该成员载波聚合的其他成员载波的上下行配置下发给接入相应成员载波的LTE-A UE。 Corresponding to the access of the carrier under the LTE-A UE [0054] Step 202, the upper and lower rows of each carrier member and disposed with the polymeric carrier of the other downlink component carrier configuration.

[0055] 本步骤中,具体下发上下行配置的方式可以为:通过在每个载波上的广播消息或该载波的高层信令通知接入相应载波的UE。 [0055] In this step, particularly arranged vertically issued lines may include: notifying the access through a broadcast message on each carrier of the carrier or carriers of the high layer signaling corresponding UE.

[0056] 下发与某载波A聚合的其他成员载波的上下行配置的方式也可以有多种,例如, 将与某载波A聚合的每个其他成员载波的上下行配置依次下发,或者采用增量下发的方式,即首先通知UE是否与载波A的上下行配置相同,再将与载波A的上下行配置不同的那些成员载波的上下行配置依次下发,或者,还可以直接在其他成员载波与载波A的上下行配置不同时,才下发其他成员载波的上下行配置,否则认为其他成员载波与载波A的上下行配置相同。 [0056] issued by the polymerization of a carrier A vertically arranged rows of other members may have a variety of carriers, for example, the upper and lower rows arranged every other component carrier and a polymeric carrier A issued sequentially, or with issued increments under way, i.e., first notifies the UE whether the configuration is the same uplink and downlink carrier a, then the uplink and downlink carrier a configuration different from those members vertically arranged rows carriers are issued, or, in other further directly uplink and downlink configuration carriers and carrier a is not at the same time, it issued the other members of the uplink and downlink carrier configuration, or that the other members of the same uplink and downlink carriers and carrier a configuration.

[0057] 优选地,为保证向R8的向下兼容,还可以将每个成员载波的上下行配置下发给接入相应载波的LTE UE,使LTE UE可以在LTE-A系统中发送和接收数据。 [0057] Preferably, in order to ensure the downward compatibility to R8 may also be distributed to the corresponding carrier LTE UE in the access configuration for each downlink component carrier, so LTE UE may send and receive in the LTE-A system, data. 这时,可以在任一载波A上将成员载波A和其他成员载波的上下行配置利用不同的物理资源或逻辑资源下发,例如,使用不同的广播信道或封装在不同的数据包中下发,从而使LTE UE只接收本载波的上下行配置,使LTE-A UE能够接收本载波以及其他成员载波的上下行配置。 In this case, either send downlink a carrier A on carrier A and the other component carrier configuration using different physical resources or logical resources under, for example, using a different broadcast channel or encapsulated issued at different data packets, so that the LTE UE receives only the downlink carrier of the present configuration the LTE-a UE can receive downlink carrier and other carriers of the present configuration.

[0058] 至此,本发明中基本的上下行配置方法流程结束。 [0058] Thus, the present invention is arranged in substantially vertical rows process flow ends.

[0059] 与上述上下行配置方法相应的,本发明还提供一种上下行配置的接收方法。 [0059] to the vertical line corresponding configuration method, the present invention also provides a method for receiving uplink and downlink configuration. 在该接收方法中,由LTE-A UE进行上下行配置的接收,具体即将基站下发的各个载波的上下行配置以及与该载波聚合的其他载波的上下行配置进行接收,从而在后续进行数据传输过程中,可以利用多个载波聚合进行数据传输,以提高系统数据传输带宽。 In this receiving method, receiving vertically arranged row by the LTE-A UE, specifically about to the base station delivers the uplink and downlink each carrier configuration and polymerized with the carrier upper and lower row of other carriers is configured to receive, so that the data in a subsequent performed during transmission, the polymerization may utilize multiple carriers for data transmission, data transmission bandwidth in order to improve the system. 同时,由于上述本发明在进行上下行配置时,还可以将每个载波的上下行配置通过相应载波下发给接入该载波的LTE UE,因此,在LTE UE也能够接收基站下发的该LTE UE所接入载波的上下行配置。 Meanwhile, since the above-described configuration of the present invention, when performing uplink and downlink, uplink and downlink can also be configured for each carrier under the respective carrier by LTE UE to the access of the carrier, therefore, capable of receiving by the base station in the LTE UE the LTE UE access carrier downlink configuration. 具体的, specific,

[0060] 对于接入每一LTE TDD载波的UE,需要获知本载波的上下行配置,具体是通过该载波上发送的广播消息得知; [0060] For each access the UE LTE TDD carrier, the carrier needs to know the present configuration of uplink and downlink, particularly a broadcast message is sent on the carrier by known;

[0061] 对于接入每一LTE-TDD载波的LTE-A UE,需要获知与该载波聚合提供更大传输带宽的其他载波的上的上下行配置,具体获知方式可以为: The vertical lines on the [0061] For each access LTE-TDD carrier LTE-A UE, needs to obtain a larger transmission bandwidth to provide the carrier aggregation configurations other carriers, the specific mode may be known:

[0062] A)通过本载波上的广播消息获知,即每个载波除了广播本载波的上下行配置信息外,还广播其他聚合载波的上下行配置信息。 [0062] A) through a broadcast message on this known carriers, i.e. each carrier in addition to the broadcast carrier of the present uplink and downlink configuration information, but also other polymeric carriers broadcast uplink and downlink configuration information. 该广播消息也可以采用增量方式发送,即先分别通知各个载波上的上下行配置与本载波是否相同,而后仅广播与本载波配置不同的成员载波上的上下行配置信息。 The broadcast message may be transmitted incrementally, i.e., first notifies the vertical lines on each carrier configuration is the same as the present carrier, then only the present broadcast carrier arranged on different uplink and downlink configuration information carrier.

[0063] B)通过本载波上的高层信令获知,例如建立RRC连接时通知。 [0063] B) by a high layer signaling according to the known carriers, for example, the RRC connection establishment notification. 类似地,本高层信令也可以采用增量方式通知,即只有当其他载波与本载波上下行配置不同时才通知具体的上下行配置信息,否则仅指示对应载波与本载波上下行配置相同。 Similarly, the higher layer signaling may be incrementally notification, i.e. only when the other carriers and vertical carriers of the present notice specific uplink and downlink configuration information when different, or only indicate corresponding DL carrier and local carrier identical configuration.

[0064] 通过上述方式即实现了LTE-A系统中的上下行配置以及接收,这样,为给UE提供更大的系统带宽创造了条件。 [0064] By the above-described manner of achieving the uplink and downlink of LTE-A system configuration and a receiver, so that, the UE creates conditions provide greater system bandwidth. 在进行上述配置后,优选地,由于存在更大带宽的需求,当某LTE-A UE需要在多个载波上同时接收或发送数据时,可以将该LTE-A UE调度在聚合的多个成员载波上同为上行或下行的子帧上。 After performing the above-described configuration, preferably, since there is a greater demand for bandwidth, when an LTE-A UE needs to receive or transmit data simultaneously on multiple carriers, the LTE-A UE may be scheduled in a plurality of polymerization members on the same sub-carrier of an uplink or downlink frames.

[0065] 例如,若某一LTE-A UE需要更大的下行带宽(需要在多个载波上同时接收数据), 则基站可以在聚合的多个载波中选择部分载波,并将该LTE-AUE调度在这些载波上同为下行的子帧上,如图5所示。 [0065] For example, if an LTE-A UE requires more downlink bandwidth (data to be received simultaneously on multiple carriers), the base station may select a plurality of carrier portions carrier aggregation, and the LTE-AUE a sub-frame scheduled on the same downlink carrier such as shown in FIG.

[0066] 对于上行更大带宽的支持也采用类似的方法,如图6所示。 [0066] For the uplink can support greater bandwidth using a similar method, as shown in FIG.

[0067] 另外,在实施本发明的过程中,还需要保证不同载波上的LTE-TDD系统之间保持精确同步,具体包括无线帧对齐以及子帧对齐。 [0067] Further, in the practice of the present invention, it is also necessary to ensure accurate synchronization between the holding LTE-TDD systems on different carriers, the radio frame comprises alignment and a sub-frame alignment.

[0068] 由上述本发明的具体实现可见,本发明解决了LTE-A TDD系统不同成员载波上的上下行配置问题,在进行上下行配置时,可以根据需要为将成员载波配置为符合R8的上下行配置,以实现向R8的向下兼容,或者也可以采用其他合适的上下行配置,以实现更好的传输性能。 [0068] by the particular implementation of the present invention can be seen, the present invention addresses on different uplink and downlink carrier LTE-A TDD system configuration problem when performing uplink and downlink configurations, the carrier may be configured to conform to the required R8 DL configuration, in order to achieve backward compatibility to R8, or other suitable uplink and downlink configuration may be employed in order to achieve better transmission performance.

[0069] 以上仅为本发明的较佳实施例而已,并非用于限定本发明的保护范围。 [0069] The above embodiments of the present invention is merely preferred and not intended to limit the scope of the present invention. 凡在本发明的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。 Any modification within the spirit and principle of the present invention, made, equivalent substitutions, improvements, etc., should be included within the scope of the present invention.
