Description

资源分配信息的指示方法及指示信息的传输方法、装置技术领域本发明涉及通信物理层技术,特别涉及资源分配信息的指示方法,以及资源分配指示信息的传输方法及装置。 Transmission method information indicating a method of resource allocation information and instructions, TECHNICAL FIELD The present invention relates to a physical layer of communication technology, particularly relates to a method and apparatus for transmitting resource allocation information indicating a method, and a resource allocation instruction information. 背景技术高速下行分组接入(HSDPA, High Speed Downlink Packet Access)技术中的调度信令。 BACKGROUND scheduling signaling speed downlink packet access (HSDPA, High Speed ​​Downlink Packet Access) technology. 在现有的HSDPA技术中,多个用户数据共同复用在具有一定确知范围的物理资源上,不同的时间传输单元可以复用不同的用户。 In conventional HSDPA technology, a plurality of user data multiplexed on a common physical resource ascertain a certain range, a transmission unit may be a different time multiplexing different users. 为了使用户能够准确的收到基站下发的数据,基站需要预先通知用户一定的与数据接收相关的信令,这些信令称为调度信令,在调度信令中包括:资源分配指示信息,为7比特;用户终端标识(UEID, User Equipment IDentity),为16比特。 In order to enable users to receive accurate data delivered by the base station, the base station needs to notify the user in advance some signaling associated with the data received, the signaling is called scheduling signaling, including in the scheduling signaling: resource allocation indication information, is 7 bits; user terminal identity (UEID, user Equipment iDentity), 16 bits. 其中,资源分配指示信息是指基站下发的数据所占用的物理资源的位置和大小的信息,通知这些信息的目的是为了用户能够在相应的物理资源位置上接收到这些数据;UE ID是系统中唯一标识某个UE的身份识别码。 Wherein, the resource allocation instruction information refers to information of the position and the size of the physical resource sent by the base station occupied by the data, notification purposes this information to the user can receive the data in the corresponding physical resource location; UE ID is the system identification code that uniquely identifies a UE. 当调度信令由基站下发后,用户首先辨识UEID信息,确认本次调度信令中是否有自己的信息,如果有,根据信息比特组分别确定相应的时间传输单元上,基站下发给自己的数据所占用的物理资源的位置以及大小的信息,从而确保数据能够被正确接收,恢复出原始信息。 When scheduling signaling issued by the base station after, first user identification information UEID confirm whether their information present scheduling signaling, if any, are determined based on the information sent to his next bit group corresponding time transmitting unit, the base station position and size information of physical resources occupied by the data, to ensure that data can be received correctly, to recover the original information. 目前有一种利用比特位图进行资源分配指示的方法,图l为比特位图的资源分配指示信息示意图,如图所示,每个UE的资源分配指示信息都采用比特位图(bitmap):假设系统可供分配的物理资源单元(RU, Resource Unit)为N 个(设起点处为物理资源单元1,后续叙述以此为准),每个物理资源单元对应l个比特,如果一个物理资源单元分配给了这个UE,则相应比特置位为1;如果没有分配给该UE,则置位为0 (或者置位相反,以下仅以此种置位为例)。 Currently there is a method of using bitmap resource allocation indicated in FIG l is a schematic diagram of resource allocation information indicating the bitmap, as shown, the resource allocation information indicating each UE are used bitmap (bitmap): Suppose the system for allocating physical resource unit (RU, resource unit) into N (provided the starting point is a physical resource unit, the subsequently described are based on this), each physical resource unit corresponding to the l th bit, if a physical resource units allocated to the UE, the corresponding bit is set to 1; if not allocated to the UE, the bit is set to zero (or set the contrary, the only set this example). 把资源分配指示信息放置在分配给该UE的第一个物理资源单元上。 The resource allocation indication information is placed on the first physical resource unit allocated to the UE. 不同标号的方框代表分配给不同UE的物理资源单元,下方是该UE的对应的资源分配指示信息的bi加ap。 Block representing different numerals are assigned to different physical resource units UE, below the corresponding resource allocation information indicating the UE bi plus ap. 不同的箭头指示了该bitmap放置的位置。 The arrows indicate the different position of the bitmap is placed. 每个UE /人第一个物理资源单元开始逐个对物理资源单元检测和匹配,判断是否有自己相关的资源分配指示信息。 Each UE / person starts the first physical resource unit one by one physical resource unit detects a match and determines whether the relevant resource has its own allocation indication information. 一旦匹配成功,就默认这是分配给自己的第一个物理资源单元,检测和匹配过程结束。 Once a match is found, it is assigned to default on their first physical resource units to detect and stop the matching process. 解码出资源分配指示信息, 后续的物理资源单元分配情况通过bitmap中的信息获得。 Decoding the resource allocation information indicating the subsequent physical resource unit allocation obtained by the information in the bitmap. 如图1中的UE 2,通过UE ID匹配判断系统的物理资源单元2是分配给自己的第一个物理资源单元,之后通过解码出资源分配指示信息bitmap,才艮据各个的比特的置位情况得出系统物理资源单元2, 3, 5, 7是分配给自己的物理资源单元。 FIG 2 in the UE 1, UE ID by matching the physical resource determination unit system 2 is allocated to itself in a first physical resource unit, then by decoding the information indicative of the resource allocation bitmap, only Gen set according to the respective bits derived systems where physical resource units 2, 3, 5, 7 are assigned to their own physical resource units. 现有技术中,每个UE的资源分配指示信息都放在分配给该UE的第一个物理资源单元上,假设分配给的UE第一个物理资源单元是系统中的物理资源单元n,那么bitmap信息中前n个比特必然是O......01,如图1箭头以及箭头前的比特。 In the prior art, resource assignment information indicating each UE are on a first physical resource unit allocated to the UE, the UE is assumed to assign a first physical resource is a physical resource unit n units in the system, then bitmap information of the first n bits must be O ...... 01, and a bit before the arrow in FIG. 1 by arrows. 在实际的调度信令传输时, 一旦用户在某个物理资源单元(n)上匹配到了自己的资源分配指示信息,那么这前n个比特是固定序列为已知信息, 在调度信令中传输已知信息显然是一种浪费,也就是在现有技术中存在的调度信令有不必要开销的不足。 In actual scheduling signaling, once the user on a physical resource unit (n) matched to their resource allocation indication information, then this is the first n-bit fixed sequence information is known, the transmission scheduling signaling known information is clearly a waste, which is present in the prior art scheduling signaling deficiencies unnecessary overhead. 速率匹配是指:信道编码器输出的原始比特序列是固定编码速率的,与实际物理信道中需要的编码速率可能会存在一定差异。 Rate matching refers to: an original bit sequence output from the channel encoder is a fixed coding rate, and the actual physical channel encoding rate may require certain differences. 因此需要重复或者凿掉原始比特序列中的一些比特。 Therefore, repeat or chisel away some of the bits of the original bit sequence. 速率匹配就是指原始比特序列被重复(Repeating) 或者凿孔(Puncturing )以便使信道映射时达到传输格式所要求的比特速率。 Rate matching refers to the original bit sequence is repeated (Repeating) or bore (Puncturing) in order to achieve the required bit-rate transmission format of the channel mapping. "凿孔"是按照一定的算法凿去某些位置的比特;"重复"则按照一定的算法在某些位置插入重复比特。 "Punctured" chisel according to certain algorithms to certain bit position; "repeat" In certain repetitive bit insert positions according to a certain algorithm.

也就是将一定的信道编码后的比特序列通过一定规则的重复或者凿孔等方式,变换成目标长度或者冗余度的序列。 I.e. the bit sequence by the constant channel coding certain rules is repeated or punctured, etc., into a sequence of the target length or redundancy. 如输入序列是l/3编码序列,通过凿孔变换成1/2编码序列;同理输入是100个编码后比特,通过凿孔变换成80 个比特。 The input sequence is l / 3 coding sequence, the coding sequence punctured into 1/2; Similarly after 100 input coded bits by puncturing converted into 80 bits. 发明内容本发明提供了一种通信系统中资源分配指示信息的传输方法及装置,用以解决现有技术中通信系统中存在的调度信令有不必要开销的问题。 The present invention provides a transmission method and apparatus in a communication system resource allocation indication information, to solve prior art communication system in question present in the scheduling signaling unnecessary overhead. 本发明中通过对资源分配指示信息的规律总结,提供了一种使用更少信息量来对资源分配进行指示的方法,更进一步的提供了对这种方法所指示的资源分配指示信息的传输方法及装置。 The present invention, by the law of the resource allocation information indicating the summary, provides a method of using less information to indicate resource allocation method, and further provides a method for transmitting resource assignment information indicative of this method indicated and devices. 本发明一种通信系统中资源分配信息的指示方法的技术方案包括如下步骤:确定分配给用户设备的第一个物理资源单元的位置;对所述用户设备,根据所述第一个物理资源单元之后的物理资源单元的分配情况确定比特序列。 A communication system according to the present invention is indicated in the method aspect of resource allocation information comprising the steps of: determining the position assigned to the first physical resource units of a user equipment;

UE2: 10101000; LIE3: 0111。 In conjunction with FIG. 1, for convenience of description, the definition of the prior art transmission bit sequence is a first bit sequence, the bit sequence is transmitted in the present invention, a second bit sequence, the first bit sequences are: UE 1: 1001000000, l n 2: 0110101000, UE3: 0000010111; seen from FIG. 2, in the present invention a second bit sequence, i.e. a bit sequence after the first physical resource units are: UE 1: 001000000; UE2: 10101000; LIE3: 0111 . 显然,本发明通过减少对已知信息的传输解决了减少了调度信令中不必要的开销的技术问题。 Obviously, the present invention is by reducing the information transmission solutions known scheduling reduce unnecessary signaling overhead technical problems. 根据以上技术构思,本发明提供了一种通信系统中资源分配信息的指示方法,实施时,先确定分配给用户设备的第一个物理资源单元的位置;对所述用户设备,根据所确定的第一个物理资源单元之后的物理资源单元的分配情况确定比特序列。 According to the above technical concept, the present invention provides a method of indicating the resource allocation information in a communication system implementation, to determine the location of the first physical resource unit allocated to the user equipment; the user equipment, according to the determined allocation of physical resource units after the first physical resource unit determines a sequence of bits. 利用该比特序列即可对资源分配信息进行指示,可以看出用本发明指示方法能够比现有技术更加简单,节约了用于指示信息的比特数。 With this bit sequence to indicate the resource allocation information, it can be seen with the method of the present invention can indicate simpler than the prior art, save for indicating the number of bits of information. 根据上述4支术构思,本发明还提供了一种通信系统中资源分配指示信息的传输方法。 According to the above-described four operation concept, the present invention also provides a method for transmitting a communication system resource allocation indication information. 图3为本发明资源分配指示信息的传输流程示意图,如图所示,包括如下步骤:步骤301 、确定分配给用户设备的第一个物理资源单元的位置; 步骤302、对于该用户设备,根据步骤301中所确定的第一个物理资源单元之后的物理资源单元分配情况确定第二比特序列; 步骤303、向用户设备发送第二比特序列;步骤304、用户设备根据第二比特序列来确定分配给自己的物理资源单元。 Figure 3 a schematic flowchart of a transmission resource allocation information indicating the present invention, as shown, includes the following steps: Step 301 determines a position of the first physical resource units allocated to a user device;

then the rate matching by the scheduling signaling to the user equipment after transmitting the scheduling signaling standard length. 优选实施中,步骤303还可以按如下方式实现: 将第二比特序列复制至与第一比特序列等长; 向用户设备发送复制后的第二比特序列。 In a preferred embodiment, step 303 may also be implemented as follows: the second bit sequence to a copy of the first bit sequence of equal length; transmitting a second copy of the bit sequence to the user equipment. 其中的复制可以按第二比特序列比特顺序依次复制至与第一比特序列等长。 Wherein replication can replicate in sequence with the first length to the second bit sequence according to other bit sequence order. 实施中,简单的将后(Nn)个比特重复到前n个位置,补满为止。 Embodiment, a simple rear (Nn) bits before repeating n locations filled. Nn>-n时,重复Nn中的n个,具体是哪n个可以收发双方约定;Nn〈n时,多次重复最后的Nn个比特,补满为止。 Nn> When -n, Nn of the n repeating, particularly the n which can send and receive sides agreed; Nn <n, the last repeated Nn bits filled. 图4为复制后比特位图的资源分配指示信息示意图,如图所示,根据第二比特序列复制后的序列为:UE 1: 0001000000; UE2: 1010101000; UE3: 0111010111。 FIG 4 is a copy of the resource allocation bitmap information indicating a schematic view, as shown in FIG sequence according to the second copy bit sequence is: UE 1: 0001000000; UE2: 1010101000; UE3: 0111010111. 根据上述发明构思,本发明还提供了一种运用资源分配指示信息方法的传输装置,下面结合附图对本装置的具体实施进行说明。 According to the inventive concept, the present invention further provides an apparatus for transmitting resource allocation information indicating the use of the method, a specific embodiment of the present apparatus will be described below in conjunction with the accompanying drawings. 图5为运用资源分配指示信息方法的传输装置结构示意图,如图所示,装置中包括用户设备、第一确定模块501、第二确定模块502、传输模块503。 5 is a schematic view of the transmission apparatus using a resource allocation configuration information indicating a method, as shown in FIG apparatus comprises a user equipment, a first determining module 501, a second determining module 502, transmission module 503. 第一确定才莫块确定分配给用户设备的第一个物理资源单元的位置;第二确定才莫块对所述用户设备,才艮据第一个物理资源单元之后的物理资源单元的分配情况确定比特序列。 The first block is determined only Mo is assigned to determine the physical location of a resource unit of the first user device; a second block of Mo was determined on the user equipment, only physical resource allocation according Gen cell after the first physical resource units determine a bit sequence. 传输模块向用户设备发送比特序列;用户设备4艮据比特序列来确定分配给自己的物理资源单元。 Transmission module transmission bit sequence to a user equipment; Gen user equipment 4 data bit sequence to determine their assigned physical resource units. 优选实施中,传输模块可以包括速率匹配单元、发送单元,速率匹配单元将比特序列通过速率匹配成标准比特序列长度 In preferred embodiments, the transmission module may include a rate matching unit, a transmitting unit, a rate matching unit rate matching bit sequence by the standard bit sequence length
