Description

动态分配资源的分配方法 Dynamic allocation of resources allocation method

技术领域 FIELD

[0001] 本发明涉及通信领域,尤其涉及一种动态分配资源的分配方法。 [0001] The present invention relates to communication field, and particularly relates to a method for allocating dynamic allocation of resources. 背景技术 Background technique

[0002] 3GPP (第三代协作项目组织)在3G (第三代移动通信技术)规范的版本Released 中引入了高速下行分组接入(HSDPA,Highspeed downlink Packet Access)特性,其目的在于提供更高速率的下行分组业务,增大下行容量。 [0002] 3GPP (third generation cooperation project organization) in the 3G (third generation mobile communication technology) specification version Released introduced high speed downlink packet access (HSDPA, Highspeed downlink Packet Access) characteristics, and its object is to provide higher downlink packet service rate, the downlink capacity is increased. 基于UMTS (通用移动通信系统)R4构架, HSDPA通过引入自适应编码调制(AMC,AdaptiveModulation and coding)、混合自动重传请求(HARQ, HybridAutomatic Retransmission Request)等技术来达至Ij上述目的。 Based on the UMTS (Universal Mobile Telecommunications System) architecture R4, HSDPA by introducing adaptive modulation and coding (AMC, AdaptiveModulation and coding), hybrid automatic repeat request (HARQ, HybridAutomatic Retransmission Request) and other techniques to achieve the above object Ij.

[0003] UTRAN(UMTS地面无线接入网)中定义了一系列和HSDPA相关的物理信道、传输 [0003] UTRAN (UMTS Terrestrial Radio Access Network) are defined in HSDPA and associated series of physical channels, transport

信道以及处理过程。 Channels and processes. 下行数据分组以突发的方式复用到下行传输信道------高速下行共 Downlink data packets in a burst manner multiplexed downlink high speed downlink transport channel co ------

享信道(HS-DSCH, High Speed Downlink Shared Channel),传输信道HS-DSCH 再映射到高速物理下行共享信道(HS-PDSCH, High Speed PhysicalDownlink Shared Channel),该物理信道为小区内多个用户以时分或者码分的方式共享。 Shared channel (HS-DSCH, High Speed ​​Downlink Shared Channel), a transport channel HS-DSCH and then mapped to a high speed physical downlink shared channel (HS-PDSCH, High Speed ​​PhysicalDownlink Shared Channel), the physical channel in the cell a plurality of users in a time division or code division sharing manner. HS-PDSCH传输时间间隔(TTI, TransmissionTime Interval)是5ms。 HS-PDSCH transmission time interval (TTI, TransmissionTime Interval) is 5ms. HS-PDSCH 承载用户的数据信息,而用于HS-PDSCH 接收的相关控制信息通过伴随的高速共享控制信道(HS-SCCH)来传输,一条HS-SCCH对应于一条高速共享信息信道(HS-SICH),用于上行反馈信息的传递。 HS-PDSCH carries user data, while the control information for the associated HS-PDSCH transmitted by the reception of a high speed shared control channel associated (HS-SCCH), an HS-SCCH corresponding to a high speed shared information channel (HS-SICH ) for transmitting uplink feedback information. 这三种物理信道都是以5msTTI为单位进行处理和传输的,并且是多用户共享的。 These three physical channels are to process and transmit 5msTTI as a unit, and is shared by multiple users. 除此之外,为了RRC信令的传送, 3GPP在R5中还定义了上下行的伴随物理信道,用于承载跟HSDPA相关的RRC信令。 In addition, in order to transmit RRC signaling, 3GPP R5 is also defined in the accompanying uplink and downlink physical channel used to carry RRC signaling associated with the HSDPA.

[0004] 在3GPP LCR TDD (低码片速率测试驱动开发)标准中,每个物理子帧时长为5ms, 每个子帧有7个常规时隙和3个特殊时隙组成,如图1所示。 [0004] In 3GPP LCR TDD (Low Chip Rate Test driven development) standard, the physical length of each subframe is 5ms, each subframe has seven regular time slots and three special time slots, shown in Figure 1 . 在7个常规时隙中,时隙TSO 总是分配给下行链路,TSl总是分配给上行链路,其他常规时隙则可以灵活地配置为上行或下行链路,但上行时隙需连续配置。 Seven regular time slots, the time slot is always allocated to downlink TSO, TSl is always assigned to the uplink, other conventional slot can be flexibly configured to uplink or downlink, but the uplink time slots required continuous configuration. 目前在HS-SCCH信道上使用5比特信息位来向UE(User Equipment,用户设备,也成用户终端)指示时隙资源分配,支持5个时隙用于下行HS-PDSCH 信道,这5个比特固定代表了TS2、TS3、TS4、TS5、TS6。 Currently in 5 HS-SCCH channel-bit information bits to the UE (User Equipment, user equipment, but also to user terminals) indication of slot resource allocation, support for downlink slots 5 HS-PDSCH channels, five bits fixed represents TS2, TS3, TS4, TS5, TS6. 但是,在TD-SCDMA系统中,不仅仅TS2、TS3、TS4、TS5、TS6可以用于下行传输,TSO也可以用于下行传输,尤其是在多载波HSDPA系统中,辅载波上的TSO也可用于进行HS-DSCH信道的传输,然而,按现有的HS-SCCH 信令的设计则无法满足这一需求。 However, the TD-SCDMA system, only TS2, TS3, TS4, TSO TS5, TS6 can be used for downlink transmission, the TSO may be used for downlink transmission, especially in a multi-carrier HSDPA system, the secondary carrier may also be used HS-DSCH transmission in the channel, however, according to the conventional HS-SCCH signaling design can not meet this demand.

[0005] 多载波HSDPA系统就是允许一个用户的HSDPA的数据包能够同时在多个载波上传输,Node B(节点B)可以同时在多个载波上发送,UE可以在多个载波上接收HSDPA的数据。 [0005] Multi-carrier HSDPA system is to allow a user of HSDPA packets can be transmitted simultaneously on multiple carriers, Node B (Node B) may be transmitted simultaneously on multiple carriers, UE may receive a plurality of carriers on HSDPA data. 在目前的相关技术标准《中华人民共和国通信标准》讨论中,多载波HSDP系统以N 频点TD-SCDMA系统为基础实现。 In the current standards related art "PRC communication standard" discussion, a multi-carrier system N frequency HSDP TD-SCDMA system based implementation. 在N频点TD-SCDMA系统中,一个N频点小区包括多个载波,多个载波中的一个载波为主载波,其它载波为辅载波,并且仅在主载波上建立和使用公共信道,其中包括小区信标信道主公共控制物理信道(P-CCPCH)。 N frequency in TD-SCDMA system, one cell comprises a plurality of N frequency carriers, a plurality of carriers of the main carrier, a carrier other secondary carriers, and only the establishment and use of a common channel on the primary carrier, wherein a cell comprising a beacon channel primary common control physical channel (P-CCPCH). 目前的技术认为,辅载波的TSO时隙是不使用的,但是,随着辅载波数目的增多,TSO时隙不使用会造成大量的资源浪费,而且,由于HSDPA的动态调度分配资源的特性,使得TSO时隙资源可以用于HSDPA技术。 Current technology believe, TSO secondary carrier time slot is not used, however, as the number of secondary carrier, TSO time slot is not used will cause a lot of waste of resources, but also, due to the characteristics of the dynamic allocation of resources scheduling of HSDPA, such resources may be used for the time slot TSO HSDPA technology. 因此,有必要提供一种新的多载波HSDPA系统中的时隙分配指示方法,使得TSO可以用作HSDPA时隙资源,以提高频谱效率,提高多载波HSDPA系统的容量。 Therefore, it is necessary to provide a new multi-carrier HSDPA system slot allocation method for indicating that the time slot TSO HSDPA resources may be used to improve spectral efficiency, to improve the capacity of the multi-carrier HSDPA system. 该方法需要突破上述HS-SCCH信道上的时隙指示比特信息位的限制,而且不能简单的在HS-SCCH信道上将^Dit 信息扩展为6bit,因为这样会引起协议的后向兼容性问题。 The above-described method need to break HS-SCCH channel slot indication bit information bit limit, and not simply in the HS-SCCH channel extended ^ Dit 6bit information, such as backward compatibility issues caused protocol.

[0036] 下面以TD-SCDMA多载波HSDPA系统为例,结合图4对本发明的技术方案作详细说明。 [0036] In the following HSDPA multi-carrier TD-SCDMA system as an example, in conjunction with FIG. 4 aspect of the present invention will be described in detail.

[0037] 在TD-SCDMA的HSDPA系统中,时隙是动态分配资源之一,其资源单位就是一个时隙。 [0037] In the TD-SCDMA HSDPA system, the time slot is one of dynamic allocation of resources, resource unit which is a slot. 在现有的3GPP标准中,时隙资源仅仅包括一个载波上的时隙资源,包括时隙TS2、TS3、 TS4、TS5、TS6。 In conventional 3GPP standards, only the time slot resources including resource slots on one carrier, including slots TS2, TS3, TS4, TS5, TS6. 而在多载波HSDPA系统中,时隙资源可以包括多个载波上的时隙资源,而且在将TSO用作HSDPA时隙资源后,HSDPA可用的时隙资源从原来的5个增加到6个,即时隙TS0、TS2、TS3、TS4、TS5、TS6。 In a multi-carrier HSDPA system may include a slot resource timeslot resources on multiple carriers, and after the time slot TSO as HSDPA resources, slot resources available HSDPA from the original five to six, time slots TS0, TS2, TS3, TS4, TS5, TS6. 下面详细说明本发明的动态分配资源的分配方法在TD-SCDMA 多载波HSDPA系统中应。 The following detailed description of the dynamic allocation of resources allocation method according to the present invention should be in a multi-carrier TD-SCDMA HSDPA system. 在此应用中,资源分配控制信道HS-SCCH信道上的时隙分配指示位数目1=5,并分别标识为131,132几3丄4几5,如图3所示。 In this application, the resource allocation control channel indicates the number of slot assignment bit HS-SCCH channel a = 5, and 131 are respectively denoted as several hundreds 3 4 5 Shang, as shown in FIG. 当一个指示位,即比特对应于某个时隙时,如其值为1,表示该时隙被占用,如值为0,表示该时隙没有被占用。 When a bit indicates that the bit corresponding to a certain time slot, as its value is 1, the time slot is occupied, such as a value of 0 indicates that the time slot is not occupied.

[0038] 图4是根据本发明实施例的在TD-SCDMA多载波HSDPA系统中应用的动态分配资源的分配方法的流程图。 [0038] FIG. 4 is a flowchart of a method of dynamic allocation of resources allocated to applications in a multi-carrier TD-SCDMA HSDPA system according to an embodiment of the present invention. 如图4所示,该方法包括如下步骤: 4, the method comprising the steps of:

[0040] 为了充分利用现有资源,同时保证不影响一个UE同时被分配的时隙资源数目,时隙分配指示位数目固定为M = 5,同时,考虑到HSDPA技术中的资源动态调度的特点,为了简单起见,仅设定两种不同的资源组合,即(如表1所示): [0040] In order to make full use of available resources, while ensuring that the number of slots does not affect the resources allocated to a UE simultaneously, indicating the number of bits assigned fixed time slots M = 5, while taking into account the dynamic scheduling techniques HSDPA resource characteristics for simplicity, only the set of different combinations of two resources, i.e., (as shown in table 1):

[0041]时隙资源组合 1 :TS0, TS3、TS4、TS5、TS6 ; [0041] slot resource composition 1: TS0, TS3, TS4, TS5, TS6;

[0042]时隙资源组合 2 :TS2, TS3、TS4、TS5、TS6。 [0042] slot resource composition 2: TS2, TS3, TS4, TS5, TS6.

[0043] 表1 :每种时隙资源组合下的时隙与时隙指示位的关联关系 [0043] TABLE 1: relationship with the time slot TS indication bits in each time slot resource combination

Figure CN101291513BD00071

[0045] 其中,分配指示位数目可以根据需要进行设定。 [0045] wherein, indicating the number of bit allocation may be set as needed. 而且,当M = 5时,资源组合的种类也不止上述两种情况。 Further, when M = 5, the type of resource combination is also more than the above two cases.

[0046] 这些时隙资源组合及其关联关系可以通过如下配置方法配置: [0046] These compositions and the slot resource relationships may be configured by configuration:

[0047] 一、作为系统特性,不可配置信息,网络侧和/或UE可以作为已知系统信息保存。 [0047] First, as a characteristic of the system, not the configuration information, the network side and / or the UE may be a known information storage system. [0048] 二、时隙资源组合及其关联关系也可以通过高层信令配置实现。 [0048] Second, the combination of resources and their relationship may be configured to implement time slot by higher layer signaling. 即RNC(Radic) network controller,无线网络控制器)通过高层信令配置给Node B (通过物理共享信道重配置过程配置Node B)和UE (通过系统信息广播配置给UE),由Node B和UE保存。 I.e. RNC (Radic) network controller, the radio network controller) configured through higher layer signaling to the Node B (Node B reconfiguration procedure) and UE (via system information broadcast to a UE configuration) by physical shared channel, the Node B and the UE save.

[0049] 在多载波HSDPA系统中,可以在多个载波上配置HSDPA资源。 [0049] In a multi-carrier HSDPA system may be configured HSDPA resources on multiple carriers. 因此,可以为每个载波分别设定不同的时隙资源组合及其每个时隙与时隙指示位的关联关系,也可以为所有载波设定相同的时隙资源组合及其每个时隙与时隙指示位的关联关系。 Thus, resources can be set different combinations of time slots and each time slot to time slot association indicator bits for each carrier, respectively, may be set to the same time slot and the resource combinations in each time slot for all carriers relation with the slot indicator bits.

[0056] 更简单地,如果多种时隙资源组合及其每个时隙与时隙指示位的关联关系中,其中一种与现有标准中的相同,即^it时隙指示位分别对应TS2、TS3、TS4、TS5、TS6,如步骤S402中所设定的那样,那么可以在配置消息中增加一个可选配置信息来配置其他种类的时隙资源组合及其每个时隙与时隙指示位的关联关系。 [0056] More simply, if the plurality of time slots and resource combination association with each time slot in the time slot indication bit, one the same as in the conventional standard, i.e. ^ it slots respectively corresponding to bits indicating TS2, TS3, TS4, TS5, TS6, as set in step S402 above, it may be added an optional configuration information in a configuration message to configure other types of slot resource for each slot to slot combinations thereof association indication bit. 如果配置消息中没有包括该可选配置信息,则使用现有标准中的时隙资源组合及其每个时隙与时隙指示位的关联关系;否则,使用配置的其他种类的时隙资源组合及其每个时隙与时隙指示位的关联关系。 If the configuration message does not include this optional configuration information, using a combination of time slot resources in the existing standard and its associated relationship with each time slot TS indication bit; otherwise, used in combination with other configurations slot resource types its association with each time slot TS indication bit. 这样的方法可以更加容易实现相关协议的后向兼容。 Backward compatible with such an approach can be more easily implement the relevant agreements.

[0057] 在多载波HSDPA系统中,一个UE的HSDPA资源可以分配在不同的载波上。 [0057] In a multi-carrier HSDPA system, HSDPA UE may be allocated a resource on a different carrier. 因此, 在为UE初始分配HSDPA资源时,可以为每个载波分别选择并配置一种时隙资源组合及其每个时隙与时隙指示位的关联关系,也可以为所有载波选择并配置一种时隙资源组合及其每个时隙与时隙指示位的关联关系。 Therefore, when the initial allocation of HSDPA resources can select and configure one timeslot resource combination and association with each time slot TS indication bits for each carrier UE respectively, and configure all of the carriers may be selected to be a species composition slot resource and association with each time slot TS indication bit.

[0058] 步骤S406,在Node B动态调度给UE分配高速物理下行共享信道时,根据上述配置的该UE的时隙资源组合信息分配时隙资源,按该时隙资源组合下每个时隙与时隙指示位的关联关系设置HS-SCCH信道上的时隙指示位的值并发送给UE。 When the [0058] step S406, the dynamic scheduling Node B to a UE is allocated a high speed physical downlink shared channel, according to the slot resource allocation composition slot resource information of the UE configured as described above, at the time slot for each time slot and resource combination association TS indication bit set value of HS-SCCH channel slot indication bit and sends the UE.

[0059] 在Node B动态调度为UE分配高速物理下行共享信道(HS-PDSCH)资源时,根据步骤S404中为该UE配置的时隙资源组合为该UE分配时隙资源。 When the [0059] dispensing high speed physical downlink shared channel (HS-PDSCH) resources in the Node B for the UE dynamic scheduling according to the resource combination in the time slot configuration for the UE S404 step timeslot resources allocated to the UE. 如步骤S402中所设定的那样,如果该UE配置的是时隙资源组合1,则Node B在TSO,TS3、TS4、TS5、TS6这5个时隙中为该UE分配时隙资源;如果该UE配置的是时隙资源组合2,则Node B在TS2,TS3、TS4、 TS5、TS6这5个时隙中为该UE分配时隙资源。 As set in step S402 above, if the UE is configured a slot resource combination, a Node allocating resources to the UE B in slot TSO, TS3, TS4, TS5, TS6 five slots; if the slot is configured for the UE resource combination 2, a Node allocating resources to the UE B in slot TS2, TS3, TS4, TS5, TS6 five slots. 在确定分配时隙资源后,Node B按该时隙资源组合下每个时隙与时隙指示位的关联关系,将分配时隙对应的时隙指示位设置为1,标识该时隙中有HS-PDSCH物理信道资源分配给该UE,并通过资源分配控制信道HS-SCCH发送给UE。 After determining the allocation of timeslot resources, Node B by association with each time slot in the time slot indication bit slot resource combination, the slot corresponding to slot assignment indicator bit is set to 1, the time slot identifier has HS-PDSCH physical channel resources allocated to the UE, by the resource allocation control channel HS-SCCH to the UE.

[0060] 在多载波HSDPA系统中,一个UE的HSDPA资源可以分配在不同的载波上,而且, Node B在为UE动态调度分配HS-PDSCH物理信道资源时,每个载波是分别通过不同的HS-SCCH信道独立进行分配的。 [0060] In a multi-carrier HSDPA system, HSDPA resources to a UE may be allocated on different carriers, and, Node B when the UE dynamic scheduling assignment HS-PDSCH physical channel resources, each carrier are respectively different HS -SCCH independent channel allocation. 因此,对每个载波,Node B需要根据配置给该UE的该载波的时隙资源组合配置信息分配时隙资源,并按该时隙资源组合下每个时隙与时隙指示位的关联关系设置控制信道上的时隙指示位的值。 Thus, for each carrier, Node B needs to be configured according to the slot resource allocation information allocated to the UE of the carrier slot resource combination, in accordance with the relationship of each time slot in the time slot indication bit slot resource combination setting the value of the slot on the control channel indication bit.

[0061] 步骤S408,UE接收HS-SCCH信道,并根据上述配置的时隙资源组合及其每个时隙与时隙指示位的关联关系以及HS-SCCH信道上的时隙指示位的值获取时隙资源的分配情况。 [0061] Step S408, UE receives the HS-SCCH channel, and the value obtained according to the association relationship slot resource configuration and combinations thereof with each time slot and the time slot TS indication bit indicator bits HS-SCCH channel slot allocation of resources.

[0062] 如现有技术和/或标准中所述,UE接收资源分配控制信道HS-SCCH,然后根据配置的时隙资源组合及其每个时隙与时隙指示位的关联关系,解析HS-SCCH信道上的时隙指示位的值,从而获得分配的时隙资源,并进一步接收每个被分配时隙下的高速物理下行共享信道资源。 [0062] As the prior art and / or standards, the UE receives the resource allocation control channel HS-SCCH, and combinations thereof according to the slot resource association with each time slot TS indication bit configuration, parse HS TS indication bit value -SCCH channel, thereby obtaining resources allocated slots, and further receives a high speed physical downlink shared channel resources are allocated at each time slot.

[0063] 在多载波HSDPA系统中,一个UE的HSDPA资源可以分配在不同的载波上,UE分别接收每个载对应的HS-SCCH信道,并且针对每个载波,分别根据配置的该载波的时隙资源组合及其每个时隙与时隙指示位的关联关系获取该载波的时隙资源分配情况。 [0063] In a multi-carrier HSDPA system, an HSDPA UE may be allocated resources on different carriers, each carrier corresponding to the UE receives the HS-SCCH channel, and, when for each carrier separately based on the configuration of the carrier gap resource combination and association with each time slot TS indication bit slots of the carrier to acquire the resource allocation.
