Description

信息传输方法、装置、系统及用户设备 Information transmission method, apparatus, system and user equipment

技术领域 FIELD

[0001] 本发明涉及通信系统领域,特别涉及一种信息传输方法、装置、系统及用户设备。 [0001] The present invention relates to communication systems, and in particular relates to an information transmission method, apparatus, system and user equipment. 背景技术 Background technique

[0002] 移动通信系统中,有两种基本的双工方式,时分双工(TDD,Time DivisionDuplex)和频分双工(FDD, Frequency Division Duplex)。 [0002] In a mobile communication system, there are two basic duplex modes, time division duplex (TDD, Time DivisionDuplex) and frequency division duplex (FDD, Frequency Division Duplex). TDD 方式是指上行链路(UL,Uplink)和下行链路(DL,Downlink)使用同一频带,在不同的时间间隔上进行上下行信号的传输。 It refers to a TDD system Uplink (UL, Uplink) and downlink (DL, Downlink) using the same frequency band, the uplink and downlink signals are transmitted at different time intervals.

[0003] LTE (Long Term Evolution) TDD系统中,每个无线巾贞长10ms,包含10个子巾贞,每个子帧长度为1ms。 [0003] LTE (Long Term Evolution) TDD system, each wireless Chen towel length 10ms, comprising 10 sub Chen towels, each sub-frame length is 1ms. 根据不同配置,上下行链路分别使用同一频率的不同子帧进行数据传输。 Depending on configuration, the uplink and downlink use different frequency sub-frames of the same data transmission. 为了适应不同的应用场景,LTE TDD系统可以根据业务状况,改变上下行子帧配比(Uplink-Downlink Configuration),以满足不同的上下行非对称业务需求。 In order to adapt to different application scenarios, LTE TDD system according to traffic conditions, changing the uplink and downlink subframe (Uplink-Downlink Configuration), to meet the different uplink and downlink asymmetric traffic requirements.

[0004] LTE TDD系统中,上行和下行子帧的分配是静态或者半静态配置的,不能动态改变,这样的做法在宏小区大覆盖场景下较为简单有效。 [0004] LTE TDD system, the uplink and downlink sub-frame is allocated statically or semi-statically configured, can not be changed dynamically, so that in practice a large macro cell coverage scenario is simple and effective. 但是在微小区、家庭基站等小范围覆盖的小区中,用户数较少,业务需求变化更快,通常上下行子帧配比与上下行业务量不匹配,导致不能有效利用资源。 However, small-scale micro cell in a cell, like home base station coverage, the number of users is, faster changes in business requirements often do not match the uplink-downlink subframe and the uplink and downlink traffic, resulting in inefficient use of resources. 为解决此问题,LTE Rel-Il(版本11)引入动态灵活子帧配比概念,即配置一些灵活子帧(flexible subframe),每个灵活子帧可以被动态地配置成上行子帧或下行子帧,并且灵活子帧个数和位置可以根据需要改变。 To solve this problem, LTE Rel-Il (version 11) introduced the concept of dynamic and flexible subframe, i.e. subframe configure some flexibility (flexible subframe), each flexible subframe may be dynamically configured to an uplink subframe or a downlink sub frames, and the number and location of the flexible subframes may be changed as desired.

[0005] 存在灵活子帧的TDD系统中,基站可以根据业务情况动态改变灵活子帧属性,即是上行子帧还是下行子帧。 [0005] The present flexible subframe in a TDD system, the base station can dynamically change according to the service attribute flexible subframe circumstances, that is, an uplink subframe or a downlink subframe. 但是当基站改变了灵活子帧的属性时,用户设备无法获取接收到的数据当前对应的灵活子帧属性,从而造成用户设备无法根据数据当前对应的灵活子帧属性对接收到的数据进行处理,最终造成基站和用户设备无法正常通信。 However, when the base station changes the properties of a flexible subframe, the user equipment can not obtain the received data corresponding to the current sub-frame a flexible property, thereby causing the user equipment is unable to process the received data based on the data corresponding to the current sub-frame a flexible property, eventually leading to the base station and the user equipment can not communicate.

具体实施方式 Detailed ways

[0029] 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,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。 [0029] below in conjunction with the present invention in the accompanying drawings, technical solutions of embodiments of the present invention are clearly and completely described, obviously, the described embodiments are merely part of embodiments of the present invention, but not all embodiments example. 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。 Based on the embodiments of the present invention, all other embodiments of ordinary skill in the art without any creative effort shall fall within the scope of the present invention.

[0030] 为使本发明技术方案的优点更加清楚,下面结合附图和实施例对本发明作详细说明。 [0030] The advantage of the solution that the present invention clearer, the accompanying drawings and embodiments of the present invention is described in detail in conjunction.

[0031] 本发明实施例提供一种信息传输方法,如图I所示,所述方法包括: [0031] The present invention provides an information transmission method, as shown in FIG. I, the method comprising:

[0032] 101、基站确定灵活子帧属性。 [0032] 101, the base station determines flexible subframe properties.

[0033] 其中,一个灵活子帧可以根据业务需求被动态地配置成上行子帧或下行子帧,并且灵活子帧个数和位置可以根据需要改变。 [0033] wherein a flexible subframe may be changed as required according to the service needs to be dynamically configured uplink subframe or a downlink subframe, and the number and position of the flexible subframes.

[0034] 具体地,基站可以根据业务需求动态配置灵活子帧属性。 [0034] Specifically, the base station may dynamically configure the flexible subframe properties according to business needs.

[0035] 例如,LTE TDD系统中,无线帧有两大类,一类无线帧的重复周期是5ms,另一类无线帧的重复周期是10ms。 [0035] For example, LTE TDD system, there are two types of radio frame repetition period of the radio frame is a class of 5ms, another radio frame repetition period is 10ms. 对于重复周期是5ms的无线帧,子帧0和5确定为下行子帧,子帧I和6确定为特殊子帧,子帧2确定为上行子帧,其余子帧3,4,7,8和9都可以配置为灵活子帧,灵活子帧最多可以配置5个;对于重复周期是IOms的无线帧,子帧0确定为下行子帧,子帧I确定为特殊子帧,子帧2确定为上行子帧,灵活子帧最多可以配置7个,分别是3,4,5,6,7,8和9。 For the repetition period is of the 5ms radio frame, subframes 0 and 5 determined downlink sub-frames, and sub-frame I is determined as a special sub-frame 6, an uplink sub-frame 2 is determined as a subframe, the remaining subframes 3,4,7,8 and 9 can be configured as flexible subframes and flexible subframes can configure up to 5; for the repetition period is a radio frame IOms of subframe 0 is determined downlink sub-frame, the sub-frame I is determined as a special subframe, subframe 2 OK an uplink subframe, flexible subframe can configure up to 7, and 9 are respectively 3,4,5,6,7,8. 基站可以根据当前业务情况,通过某种算法确定各个灵活子帧的属性。 The base station according to the current traffic situation, to determine the properties of each flexible subframe by some algorithm. 每个灵活子帧的属性可以用I比特信息来指示,0表示下行子帧,I表示上行子帧。 Each attribute may be a flexible subframe I bit of information to indicate, 0 represents a downlink sub-frame, I represents an uplink subframe.

[0036] 102、基站向用户设备UE发送第一消息,第一消息携带灵活子帧属性。 [0036] 102, the base station transmits a first message to a user equipment UE, a message carrying the flexible subframe properties.

[0037] 具体地,基站可以将第一消息承载在物理多播信道PMCH向UE发送。 [0037] Specifically, the base station a first message may be carried in a physical multicast channel PMCH transmitted to the UE.

[0038] 本发明实施例进一步地提供了将第一消息承载在物理多播信道PMCH向UE发送的具体方法,包括: [0038] The present invention further provides a method of a first particular message carried in a physical multicast channel PMCH transmitted to the UE, comprising:

[0039] 当基站通过介质访问控制层协议数据单元的介质访问控制层控制信元向用户设备发送配置后的灵活子帧属性信息时,可以在现有的MAC CE中确定第二预设比特用于指示灵活子帧属性,即设置一种新的介质访问控制层控制信元来指示灵活子帧属性信息,如图6所示,新的介质访问控制层控制信元拥有固定长度8个比特,第一个比特作为保留比特,后面的7个比特分别指示每个灵活子帧的属性。 [0039] When the MAC layer of the base station through the control channel medium access control layer protocol data unit element, a second predetermined bit may be determined in a conventional MAC CE in the flexible subframes when the attribute information with the user equipment sends a configuration attribute indicating flexible subframe, i.e., a new set of medium access control layer, the control information element to indicate the flexible subframe attribute information shown in FIG. 6, a new media access control layer, the control cell has a fixed length of eight bits, the first bit as reserved bits, followed by 7 bits indicate the attributes of each flexible subframe. 由于LTE TDD系统中支持的最大灵活子帧数为7,因此这里用7个比特来指示。 Since the LTE TDD system supports a maximum number of subframes 7 and flexible, so here indicated by 7 bits. 当系统配置的灵活子帧数小于7时,多余的比特无效。 Flexible sub-frames when the system configuration is less than 7, the extra bit is invalid. 例如:当前系统配置了5个灵活子帧,那么只有前5个比特是有意义的,用于指示5个灵活子帧的属性,多余的2个比特当作无效信息,没有任何意义。 For example: The current system is configured with five flexible sub-frame, then only the first 5 bits are meaningful to indicate five flexible subframe property, extra two bits as invalid information, no meaning.

[0040] 可替换地,当基站通过介质访问控制层协议数据单元的介质访问控制层控制信元向用户设备发送配置后的灵活子帧属性信息时,还可以从现有的介质访问控制层控制单元格式中的MSI (MCH Scheduling Information,多播信道调度信息)中增加第一预设比特特来指示灵活子帧属性信息,如图7所示,例如,现有的介质访问控制层控制信元格式中,多播信道调度信息是可变长度的,可以在其开头或末尾增加一个8bit的信息,用于指示灵活子帧属性。 [0040] Alternatively, when the medium access control layer of the base station through the control channel medium access control layer protocol data unit to the element when the flexible subframe attribute information of the user equipment configuration may also be controlled from an existing medium access control layer unit format MSI (MCH scheduling information, the multicast channel scheduling information) added to indicate a first predetermined Bite Te flexible subframe attribute information, as shown in FIG. 7, for example, a conventional medium access control layer, the control cell format, the multicast channel scheduling information is a variable length, a 8bit information may be added at the beginning or at the end, a flexible subframe for indicating properties.

[0041] 可替换地,当基站通过将灵活子帧属性承载在多播控制信道MCCH向用户设备发送时,可以涉及一种新的消息格式指示向用户设备发送的灵活子帧属性。 [0041] Alternatively, when the base station by the flexible subframes bearing properties when multicast control channel MCCH transmitted to the user equipment, may involve a new message format sent to the user equipment indicating flexible subframe properties. 或者在多播控制信道消息中配置一个信令IE来指示向用户设备发送的灵活子帧属性,增加一个IE后的格式长度为8比特,格式为: Or arranged in a multicast control channel signaling message to indicate IE flexible subframe transmitted to the user equipment properties, increasing the length after an IE format is 8 bits, the format:

[0042] [0042]

MCCH-Message ::= SEQUENCE { MCCH-Message :: = SEQUENCE {

message MCCH-MessageType message MCCH-MessageType

} }

MCCH-MessageType ::= CHOICE { cl CHOICE { MCCH-MessageType :: = CHOICE {cl CHOICE {

[0043] [0043]

Figure CN102624490AD00081

[0044] 或者在多播控制信道消息中,通过保留字段指示需要传输的灵活子帧属性,具体地,利用多媒体广播单频网中的IateNonCriticalExtension字段来指示灵活子巾贞的属性。 [0044] or a multicast control channel message, the indication to be transmitted through the flexible subframe reserved field properties, in particular, the use of a multimedia broadcast single frequency network IateNonCriticalExtension field to indicate the properties of a flexible subframe Zhen towel. 具体使用的保留比特数为灵活子帧属性指示需要的比特数。 The number of bits of reserved bits of a frame attribute indicates the specific use of flexible subframes required.

[0045] 可替换地,基站可以通过将灵活子帧属性承载在多播业务信道MTCH向用户设备发送。 [0045] Alternatively, the base station may be carried in the flexible subframes properties multicast service channel MTCH which is transmitted to the user equipment.

[0046] 其中,多播业务信道是一种逻辑信道,用于传输多媒体广播多播业务,映射到多播信道上,最终映射到物理信道物理多播信道上发送出去。 [0046] wherein multicast traffic channel is a logical channel used for transmitting multimedia broadcast multicast service mapped to a multicast channel, finally mapped to a physical channel, a physical multicast channel transmitted.

[0047] 在LTE系统中,每个多媒体广播多播业务对应一个多播业务信道。 [0047] In the LTE system, each multimedia broadcast multicast service corresponds to a multicast service channel. 例如,对于视频点播,不同的视频节目代表不同的多媒体广播多播业务,每个节目对应一个多播业务信道。 For example, for video on demand, different video programs on behalf of multimedia broadcast multicast service, each multicast service corresponds to one program channel. 基于此,将灵活子帧属性也作为一种特殊的多媒体广播多播业务,分配一个多播业务信道与之对应,即将动态改变的灵活子帧属性可以快速通知到用户设备。 Based on this, also the flexible subframe as a special attribute of multimedia broadcast multicast service, multicast traffic is assigned a channel corresponding thereto, i.e. the flexible subframes dynamically changing properties can quickly inform the user equipment.

[0048] 每种多媒体广播多播业务的传输是由MSI (多播信道调度)来控制的,可以通过MSI对灵活子帧属性信息进行调度,在灵活子帧属性更新的时候发送更新后的灵活子帧属性,没有更新的时候就不发送,这样也可以避免资源的浪费。 [0048] Each multimedia broadcast transmission of the multicast traffic by MSI (Multicast Channel scheduler) to control, and may be scheduled flexible subframe attribute information by the MSI, flexible send an updated flexible subframe updated properties when subframe property is not updated when not sending, which would also avoid the waste of resources.

[0049] 本发明实施例提供一种信息传输装置,所述装置的实体可以为基站,如图2所示,所述装置包括:确定单元21、发送单元22。 [0049] The embodiments of the present invention to provide an information transmission apparatus, the entity may be a base station of the apparatus shown in Figure 2, the apparatus comprising: a determining unit 21, a transmission unit 22.

[0050] 确定单元21,用于确定灵活子帧属性。 [0050] 21 determination unit, for determining a property flexible subframe.

[0051] 具体地,确定单元21可以根据业务需求动态配置灵活子帧属性信息。 [0051] Specifically, the determination unit 21 can be configured dynamically flexible subframe attribute information according to business needs.

[0052] 例如,LTE TDD系统中,无线帧有两大类,一类无线帧的重复周期是5ms,另一类无线帧的重复周期是10ms。 [0052] For example, LTE TDD system, there are two types of radio frame repetition period of the radio frame is a class of 5ms, another radio frame repetition period is 10ms. 对于重复周期是5ms的无线帧,子帧0和5确定为下行子帧,子帧I和6确定为特殊子帧,子帧2确定为上行子帧,其余子帧3,4,7,8和9都可以配置为灵活子帧,灵活子帧最多可以配置5个;对于重复周期是IOms的无线帧,子帧0确定为下行子帧,子帧I确定为特殊子帧,子帧2确定为上行子帧,灵活子帧最多可以配置7个,分别是3,4,5,6,7,8和9。 For the repetition period is of the 5ms radio frame, subframes 0 and 5 determined downlink sub-frames, and sub-frame I is determined as a special sub-frame 6, an uplink sub-frame 2 is determined as a subframe, the remaining subframes 3,4,7,8 and 9 can be configured as flexible subframes and flexible subframes can configure up to 5; for the repetition period is a radio frame IOms of subframe 0 is determined downlink sub-frame, the sub-frame I is determined as a special subframe, subframe 2 OK an uplink subframe, flexible subframe can configure up to 7, and 9 are respectively 3,4,5,6,7,8. 基站可以根据当前业务情况,通过某种算法确定各个灵活子帧的属性。 The base station according to the current traffic situation, to determine the properties of each flexible subframe by some algorithm. 每个灵活子帧的属性可以用I比特信息来指示,0表示下行子帧,I表示上行子帧。 Each attribute may be a flexible subframe I bit of information to indicate, 0 represents a downlink sub-frame, I represents an uplink subframe.
