一种通信系统的调度状态指示方法及基站与用户设备A scheduling state indication method of a communication system, base station and user equipment

技术领域technical field

本发明涉及通信领域，尤其涉及一种通信系统的调度状态指示方法及对应的基站与用户设备。The present invention relates to the communication field, in particular to a method for indicating a dispatch state of a communication system and a corresponding base station and user equipment.

背景技术Background technique

现有的高速下行分组接入(High Speed Downlink Packet Access，HSDPA)技术，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数据。所以，为了用户能够准确的接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息，也叫做调度信息。主要包括：In the existing High Speed Downlink Packet Access (HSDPA) technology, multiple user data are jointly multiplexed on physical resources with a certain definite range, and different time transmission units can multiplex different user data. Therefore, in order for the user to accurately receive the data delivered by the base station, the base station needs to notify the user in advance of certain information related to data reception, which is also called scheduling information. mainly include:

资源分配指示信息；Resource allocation indication information;

调制格式信息；modulation format information;

传输块大小信息；Transmission block size information;

用户设备标识(User Equipment IDentity，UE ID)信息等。User Equipment IDentity (UE ID) information, etc.

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信息，通知这些信息的目的是为了UE能够在相应的物理资源位置上接收到发送给自己的数据。Wherein, the resource allocation indication information refers to the position and size information of the physical resources occupied by the data issued by the base station, and the purpose of notifying these information is for the UE to receive the data sent to itself at the corresponding physical resource position.

调制格式信息是指发送的数据所采用的调制方式，保证用户接收数据以后可以正确的进行解调。The modulation format information refers to the modulation mode adopted by the transmitted data, which ensures that the user can correctly demodulate the data after receiving it.

传输块大小信息是指本次传输的数据未经信道编码时的原始信息比特数量。The transmission block size information refers to the number of original information bits when the data transmitted this time is not channel-coded.

UE ID是系统中唯一标识某个UE的身份识别码。UE ID is an identification code that uniquely identifies a certain UE in the system.

当调度信息通过调度信令携带由基站下发给UE时，UE首先辨识UE ID信息，确认本次调度是否有发送给自己的数据，如果有，根据调度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起始位置和大小信息(即占用的物理资源单元的数量)，传输块大小信息和采用的调制方式，并据此推算出采用的信道编码的码率，从而确保能够正确接收发送给自己的数据并正确解调解码，恢复出基站发送的原始数据。When the scheduling information is carried by the scheduling signaling and sent to the UE by the base station, the UE first identifies the UE ID information to confirm whether there is data sent to itself in this scheduling, and if so, determine the corresponding time transmission unit according to the scheduling information bit group The starting position and size information of the physical resources occupied by the data sent by the upper base station to itself (that is, the number of occupied physical resource units), the transmission block size information and the modulation method used, and the channel coding used is calculated accordingly The code rate, so as to ensure that the data sent to itself can be correctly received and demodulated and decoded correctly, and the original data sent by the base station can be restored.

具体推算方法为：The specific calculation method is:

设每个物理资源单元可以承载的调制符号数量为N_Band；设某种传输块大小(TBSx)对应的原始比特数量为N_TBSx；设某个用户数据占用的物理资源单元的数量为N_RUx，调制阶数为M，编码码率为C，编码调制后，每个调制符号承载的原始比特数量为(log₂M)*C比特/符号，则：The number of modulation symbols that can be carried by each physical resource unit is N_Band ; the number of original bits corresponding to a certain transport block size (TBSx) is N_TBSx ; the number of physical resource units occupied by a certain user data is N_RUx , The modulation order is M, and the coding code rate is C. After coding and modulation, the number of original bits carried by each modulation symbol is (log₂ M)*C bits/symbol, then:

         C＝N_TBSx/N_RUx*N_Band*(log₂M)          (1)C＝N_TBSx /N_RUx *N_Band *(log₂ M) (1)

现有技术中(参见文献3GPP 25.212 4.6及3GPP R1-060803)，每种调度信息分别独立编码，当给每个UE分配连续的物理资源单元时，资源分配指示信息指示了连续分配的物理资源单元的起始位置信息和所占物理资源单元的数量。In the prior art (see document 3GPP 25.212 4.6 and 3GPP R1-060803), each type of scheduling information is coded independently, and when consecutive physical resource units are allocated to each UE, the resource allocation indication information indicates the continuous allocation of physical resource units The starting location information and the number of occupied physical resource units.

上述现有技术中，为了节省指示调度状态的调度信令的比特开销，所作的优化仅是基于物理资源单元的起始位置和所占物理资源单元数量之间存在的相关性，没有考虑其它调度信息之间仍然存在的相关性，因此，调度信令所占的比特数不是最优化的。In the above prior art, in order to save the bit overhead of the scheduling signaling indicating the scheduling state, the optimization is only based on the correlation between the starting position of the physical resource unit and the number of occupied physical resource units, without considering other scheduling Correlation still exists among the information, therefore, the number of bits occupied by the scheduling signaling is not optimized.

具体实施方式Detailed ways

本发明提供的通信系统的调度状态指示方法，包括：The scheduling state indication method of the communication system provided by the present invention includes:

基站根据对用户设备UE的调度状态生成相应的调度信令信息；The base station generates corresponding scheduling signaling information according to the scheduling state of the user equipment UE;

对所述调度信令信息中彼此相关的调度信息项进行联合编码后发送调度信令给UE。The scheduling information items related to each other in the scheduling signaling information are jointly encoded, and then the scheduling signaling is sent to the UE.

本发明方法的基本原理是：由于部分调度信令信息不是完全独立的，各调度信息项中实际上存在某种内在的相关性，即一旦其中某一项的取值确定下来，其他几项取值的可选范围会随之缩小。The basic principle of the method of the present invention is: because part of the scheduling signaling information is not completely independent, there is actually a certain internal correlation in each scheduling information item, that is, once the value of one of the items is determined, the other several items will be determined. The optional range of values will be narrowed accordingly.

本发明基于对任一用户，分配连续的物理资源单元，把调度信令信息中相关的调度信息项进行联合编码，考虑真实存在的可能的组合状态，剔除单独编码时存在的、而实际根本不可能存在的组合方式，大幅减少组合状态的总数，从而达到降低调度信令比特开销的目的。Based on the allocation of continuous physical resource units to any user, the present invention jointly encodes related scheduling information items in the scheduling signaling information, considers the possible combination states that actually exist, and eliminates those that exist in separate encoding but actually do not exist at all. The possible combination modes greatly reduce the total number of combined states, so as to achieve the purpose of reducing bit overhead of scheduling signaling.

考虑所要传递的调度信息是告知接收方将要发送(或接收)的数据块的大小，物理资源分配信息(包括分配的物理资源单元的位置信息和数量信息，其中，分配的物理资源单元的位置信息可以是分配的物理资源单元的起始位置信息或者结束位置信息。)以及采用何种调制编码格式。这些调度信息是相关的，通知了其中一部分，另外一部分可以推算出来；而且通知的各部分之间也存在某种相关性，可以进行联合编码，以进一步减少需占用信令比特。其中，传输块大小信息和分配给UE的物理资源单元的位置信息是必须传输的，因为这部分信息是无法推算出来的。当上述信息通知之后，鉴于分配的物理资源单元数量信息和调制编码格式之间的关系，可以只通知其中任意一个。Considering that the scheduling information to be delivered is to inform the receiver of the size of the data block to be sent (or received), the physical resource allocation information (including the location information and quantity information of the allocated physical resource unit, wherein the location information of the allocated physical resource unit It may be the start position information or the end position information of the allocated physical resource unit.) and which modulation and coding format is adopted. The scheduling information is related, one part of which is notified, and the other part can be calculated; and there is also a certain correlation between the notified parts, which can be jointly coded to further reduce the required signaling bits. Among them, the transmission block size information and the location information of the physical resource unit allocated to the UE must be transmitted, because this part of information cannot be calculated. After the above information is notified, in view of the relationship between the allocated physical resource unit quantity information and the modulation and coding format, only any one of them may be notified.

下面用具体实施例对本发明方法加以详细描述。The method of the present invention is described in detail below with specific examples.

实施例1：Example 1:

下发给UE的调度信令信息至少包含UE标识信息、UE的物理资源分配信息(包括物理资源单元的位置信息，分配的物理资源单元数量信息)、传输块大小信息；其中，对UE的物理资源分配信息和传输块大小信息进行联合编码，其余信息独立编码。The scheduling signaling information issued to the UE includes at least UE identification information, UE physical resource allocation information (including physical resource unit location information, allocated physical resource unit quantity information), and transport block size information; Resource allocation information and transport block size information are jointly encoded, and other information is encoded independently.

具体的联合编码方式可以是：The specific joint encoding method can be:

先对分配给UE的物理资源单元的位置信息和占用的物理资源单元数量信息进行第一级联合编码；Firstly, first-level joint encoding is performed on the position information of the physical resource units allocated to the UE and the quantity information of the occupied physical resource units;

再结合传输块大小信息进行第二级联合编码。Combined with the transport block size information, the second level of joint coding is performed.

物理资源分配信息有以下两种典型的表示方法。There are two typical representation methods for physical resource allocation information.

方法一：显式的指示分配的物理资源单元的位置信息和分配的物理资源单元数量信息。给出分配给某UE的物理资源单元在系统物理资源单元中的绝对位置和分配的数量，如图1所示：系统总的物理资源单元是10个，分配给UEA的是从编号4到编号6的3个物理资源单元，那么显式的指示UE的物理资源分配信息时，直接给出4和3的信息即可。多个UE的资源分配信息各自分别按照这种方法独立指示。Method 1: Explicitly indicate the location information of the allocated physical resource units and the quantity information of the allocated physical resource units. The absolute position and number of physical resource units allocated to a certain UE in the system physical resource units are given, as shown in Figure 1: the total physical resource units in the system are 10, and the ones allocated to UEA are fromnumber 4 tonumber 6 of the 3 physical resource units, then when explicitly indicating the physical resource allocation information of the UE, it is sufficient to directly give the information of 4 and 3. The resource allocation information of multiple UEs is independently indicated according to this method.

方法二：非显式的指示分配物理资源单元的位置信息和分配的物理资源单元数量信息。根据多UE间物理资源单元分配的依赖关系，联合给出所有UE的物理资源分配信息。如图2所示：一个比特对应一个物理资源单元，取值为“0”代表这个比特对应的物理资源单元是分配给某个UE的最后一个物理资源单元，取值为“1”代表这个比特对应的物理资源单元不是分配给某个UE的最后一个物理资源单元。系统总的物理资源单元是10个，根据10个比特中“0”的个数可以确定出分给了5个UE，分配情况如图2中填充不同格线的正方形表示，UE ID信息按照实际的资源分配情况排序，那么各个UE都可以根据自身ID的顺序对应找到分配给自己的物理资源。多个UE的资源分配信息一次性联合指示。Method 2: non-explicitly indicating location information of allocated physical resource units and quantity information of allocated physical resource units. According to the dependency relationship of physical resource unit allocation among multiple UEs, the physical resource allocation information of all UEs is jointly given. As shown in Figure 2: a bit corresponds to a physical resource unit, a value of "0" means that the physical resource unit corresponding to this bit is the last physical resource unit allocated to a certain UE, and a value of "1" means this bit The corresponding physical resource unit is not the last physical resource unit allocated to a certain UE. The total number of physical resource units in the system is 10. According to the number of "0" in the 10 bits, it can be determined that they are distributed to 5 UEs. The allocation situation is represented by the squares filled with different grid lines in Figure 2. The UE ID information is based on the actual Then each UE can find the physical resource allocated to itself according to the sequence of its own ID. The resource allocation information of multiple UEs is jointly indicated at one time.

无论通过以上那种资源分配信息的表示方法，所表示的信息都是分配给UE的物理资源单元的位置信息，分配的物理资源单元数量信息。Regardless of the representation method of the above resource allocation information, the represented information is the location information of the physical resource units allocated to the UE and the quantity information of the allocated physical resource units.

本实施例1中直接对物理资源分配信息和传输块大小信息进行联合编码。In the first embodiment, the physical resource allocation information and the transport block size information are jointly coded directly.

下面针对将UE的物理资源分配信息和传输块大小信息进行联合编码时，减少信令比特数进行具体分析：The following is a specific analysis of reducing the number of signaling bits when the UE's physical resource allocation information and transport block size information are jointly encoded:

参见图3，矩阵的行表示系统中支持的所有传输块大小的编号；列表示不同的分配物理资源单元的数量，根据分配的物理资源单元的数量可以映射出可以支持的传输块大小的种数。如果对应于某个分配的物理资源单元的数量，能支持某种传输块大小，则矩阵中对应的该元素置为“1”，否则置为“0”。图3仅是一个示意图，对应于某个分配的物理资源单元的数量，只能支持一组传输块大小的种数，仅是传输块大小集合中很小的一部分。从图3中可以看出，该矩阵类似于一个单位阵，只有对角元素及其附近元素为1，大部分元素都为0。这样，如果将物理资源分配信息和传输块大小信息进行联合编码，可以显著节省信令开销，至少可以节省1个比特。Referring to Figure 3, the rows of the matrix represent the numbers of all transport block sizes supported in the system; the columns represent the number of different allocated physical resource units, and the number of supported transport block sizes can be mapped according to the number of allocated physical resource units . If corresponding to the number of allocated physical resource units, a certain transport block size can be supported, the corresponding element in the matrix is set to "1", otherwise it is set to "0". Fig. 3 is only a schematic diagram, corresponding to the number of allocated physical resource units, only one set of types of transport block sizes can be supported, which is only a very small part of the set of transport block sizes. It can be seen from Figure 3 that the matrix is similar to a unit matrix, only the diagonal elements and nearby elements are 1, and most elements are 0. In this way, if the physical resource allocation information and the transport block size information are jointly encoded, the signaling overhead can be significantly saved, at least one bit can be saved.

UE接收到调度信令后，解析出调度信息；当调度信息为指示UE的下行调度信息时，执行下列步骤：After receiving the scheduling signaling, the UE parses out the scheduling information; when the scheduling information is downlink scheduling information indicating the UE, perform the following steps:

A1、由解析出的调度信息确定出基站采用的调制阶数和编码码率(如果把调制格式和编码码率看作一个变量，UE可以根据公式(1)计算出实际采用的调制格式和编码码率)；A1. Determine the modulation order and coding rate used by the base station from the parsed scheduling information (if the modulation format and coding rate are regarded as a variable, the UE can calculate the actual modulation format and coding rate according to formula (1) code rate);

A2、根据分配给自己的物理资源单元的位置信息和占用的物理资源单元数量信息接收相应数据块，用确定出的调制阶数和编码码率进行解调制和解码处理；A2. Receive the corresponding data block according to the location information of the physical resource unit allocated to itself and the quantity information of the occupied physical resource unit, and perform demodulation and decoding processing with the determined modulation order and coding rate;

当调度信息为指示UE的上行调度信息时，执行下列步骤：When the scheduling information is the uplink scheduling information indicating the UE, perform the following steps:

B1、由解析出的调度信息确定出基站指示UE采用的调制阶数和编码码率；B1. Determine the modulation order and coding rate used by the base station instructing the UE from the parsed scheduling information;

B2、根据分配给自己的物理资源单元的位置信息和占用的物理资源单元数量信息，占用相应的物理资源单元发送数据，用确定出的调制阶数和编码码率进行调制和编码处理。B2. Occupy the corresponding physical resource unit to send data according to the location information of the allocated physical resource unit and the quantity information of the occupied physical resource unit, and perform modulation and coding processing with the determined modulation order and coding rate.

实施例2：Example 2:

下发给UE的调度信令信息至少包含UE标识信息、传输块大小信息、分配给UE的物理资源单元的位置信息以及调制信息和编码信息；其中，仅对调制信息和编码信息进行联合编码，其余信息独立编码。The scheduling signaling information delivered to the UE includes at least UE identification information, transport block size information, location information of physical resource units allocated to the UE, and modulation information and coding information; where only the modulation information and coding information are jointly coded, The rest of the information is coded independently.

基于实施例1中提到的物理资源分配信息表示方法一，可以认为分配的物理资源单元的位置信息和数量信息是分别表示的，在本实施例中，调度信令信息中不包含分配给UE的物理资源单元的数量信息，但是需要增加粗粒度的编码信息(编码码率)，即不需很精确的编码码率信息，选择粗粒度的目的是为了减小信令开销。增加的粗粒度的编码码率信息保证在分配的物理资源单元数量是k的情况下，不必精确表示。根据实际采用的精确的编码码率选择接近的一种粗粒度的编码码率，选择的原则可以是保证经过计算分配的物理资源单元数量在(k-1)到k之间，即采用向较高码率看齐类似于在原码率数据的基础上再打孔的方式，以下简称打孔原则；或者在分配的物理单元数量是k的情况下，选择的原则可以是保证经过计算分配的物理资源单元数量在k到(k+1)之间，即采用向较低码率看齐类似于在原码率数据的基础上再重复的方式，以下简称重复原则。通知编码码率的目的是为了使UE能够根据所有通知的调度信息按照公式(1)粗略地计算出数据块所占用的物理资源单元数量。当所计算出的物理资源单元的数量不是整数时，根据约定，如果采用打孔原则，那么向上取整；如果采用重复原则，那么向下取整。Based on the first representation method of physical resource allocation information mentioned inEmbodiment 1, it can be considered that the location information and quantity information of the allocated physical resource units are represented separately. In this embodiment, the scheduling signaling information does not include The quantity information of the physical resource units, but the coarse-grained coding information (coding rate) needs to be added, that is, the precise coding rate information is not required, and the purpose of selecting the coarse-grained size is to reduce signaling overhead. The added coarse-grained coding rate information ensures that when the number of allocated physical resource units is k, it does not need to be accurately represented. Select a coarse-grained coding rate that is close to the exact coding rate actually used. The principle of selection can be to ensure that the number of physical resource units allocated after calculation is between (k-1) and k, that is, using a relatively The high bit rate is similar to the method of punching holes on the basis of the original bit rate data, hereinafter referred to as the punching principle; or when the number of allocated physical units is k, the selection principle can be to ensure the physical resources allocated by calculation The number of units is between k and (k+1), that is, the method of aligning with a lower code rate is similar to repeating on the basis of the original code rate data, hereinafter referred to as the repetition principle. The purpose of notifying the coding rate is to enable the UE to roughly calculate the number of physical resource units occupied by the data block according to formula (1) according to all the notified scheduling information. When the calculated number of physical resource units is not an integer, according to the agreement, if the principle of punching is adopted, then round up; if the principle of repetition is adopted, then round down.

例如：假设应当占用k个物理资源单元，而根据上述调度信令信息通知调制信息和编码码率(只是粗粒度的编码码率信息)的联合编码信息通常不能保证UE根据公式(1)计算出来的物理资源单元数量是整数，那么就选择与实际采用的编码码率最接近的粗粒度编码码率信息，如根据打孔原则使UE计算出来的物理资源单元的数量大于(k-1)小于等于k，即选择在实际编码后继续增加打孔的编码码率。UE默认此次数据块占用的物理资源单元的数量向上取整为k。实际物理资源单元的数量确定之后，一方面，它所能承载的调制符号数量也相应确定，这样，UE可以根据上述公式(1)计算出实际采用的精确的编码码率；另一方面，结合物理资源单元的位置信息就可以确定出物理资源分配信息了。For example, assuming that k physical resource units should be occupied, the joint coding information of modulation information and coding rate (only coarse-grained coding rate information) notified according to the above-mentioned scheduling signaling information is usually not guaranteed to be calculated by the UE according to formula (1) If the number of physical resource units is an integer, then select the coarse-grained coding rate information that is closest to the actual coding rate. For example, according to the principle of punching, the number of physical resource units calculated by the UE is greater than (k-1) and less than It is equal to k, that is, choose to continue to increase the coding bit rate of puncturing after actual coding. By default, the UE rounds up the number of physical resource units occupied by the data block to k. After the actual number of physical resource units is determined, on the one hand, the number of modulation symbols it can carry is also determined accordingly, so that the UE can calculate the exact coding rate actually used according to the above formula (1); on the other hand, combined with The location information of the physical resource unit can determine the physical resource allocation information.

下面针对将调制信息和编码信息进行联合编码时，减少信令比特数进行具体分析。The following specifically analyzes the reduction of the number of signaling bits when the modulation information and the coding information are jointly encoded.

设系统支持的调制格式数量是N_M种，支持的粗粒度的编码码率的数量是N_C种，如果不进行联合编码，则传输这两种信息需要[log₂(N_M*N_C)]个比特；如果进行联合编码设联合编码后共有调制编码格式N_MCS种，则需要[1og₂N_MCS]个比特，后者要小于等于前者。Assume that the number of modulation formats supported by the system is N_M types, and the number of supported coarse-grained coding rates is N_C types. If joint coding is not performed, the transmission of these two types of information requires [log₂ (N_M *N_C ) ] bits; if joint coding is performed and there are N_MCS modulation and coding formats after joint coding, [log₂ N_MCS ] bits are required, and the latter must be less than or equal to the former.

当系统中的物理资源单元数量为N_RU，系统支持的传输块大小的数量为N_TBS，则实施例2中，调度信息所需的比特数通过式(2)计算：When the number of physical resource units in the system is N_RU , and the number of transport block sizes supported by the system is_NTBS , then inEmbodiment 2, the number of bits required for scheduling information is calculated by formula (2):

         [log₂N_TBS]+[log₂N_RU]+[log₂N_MCS]         (2)[log₂ N_TBS ]+[log₂ N_RU ]+[log₂ N_MCS ] (2)

现有技术各调度信息项单独编码时对应的比特数通过式(3)计算：The number of bits corresponding to each scheduling information item in the prior art is calculated by formula (3):

         [log₂N_TBS]+2[1og₂N_RU]-1+[log₂N_M]        (3)[log₂ N_TBS ]+2[log₂ N_RU ]-1+[log₂ N_M ] (3)

二者之间的差值通过式(4)计算：The difference between the two is calculated by formula (4):

         [1og₂N_RU]-1+[1og₂N_M]-[1og₂N_MCS]         (4)[log₂ N_RU ]-1+[log₂ N_M ]-[log₂ N_MCS ] (4)

实施例2所述方法适用于调制编码信息所需比特开销小于物理资源单元数量信息所需比特开销；简单的说，该方法适用于物理资源单元比较多的情况。The method described inEmbodiment 2 is applicable to the case where the bit overhead required for modulation and encoding information is smaller than the bit overhead required for information on the number of physical resource units; in short, the method is applicable to the case where there are many physical resource units.

实施例3：Example 3:

下发给UE的调度信令信息至少包含UE标识信息、传输块大小信息、分配给UE的物理资源单元的位置信息、调制信息和编码信息；其中，仅对传输块大小信息和分配给UE的物理资源单元的位置信息进行联合编码，其余信息独立编码。The scheduling signaling information issued to the UE includes at least UE identification information, transport block size information, location information of physical resource units allocated to the UE, modulation information, and coding information; among them, only the transport block size information and the allocated to the UE The location information of the physical resource unit is coded jointly, and the remaining information is coded independently.

由实施例2的分析可知：UE可以通过计算得出全部需要的调度信息。From the analysis ofEmbodiment 2, it can be seen that the UE can obtain all the required scheduling information through calculation.

下面对将传输块大小信息和分配给UE的物理资源单元的位置信息进行联合编码时，减少信令比特数进行具体分析：The following is a specific analysis of reducing the number of signaling bits when jointly encoding the transport block size information and the location information of the physical resource unit allocated to the UE:

参见图4，矩阵的行表示系统中支持的所有传输块大小的编号；列表示不同的物理资源单元起点位置编号，从某个物理资源单元起点开始，根据可能占用的物理资源单元的数量可以映射出可以支持的传输块大小的种数。如果从某个起点开始，能支持某种传输块大小，则矩阵中对应的该元素置为“1”，否则置为“0”。由图4可见，随着物理资源单元的起点逐渐靠后，那么从这个起点开始可以占用的物理资源单元的数量逐渐减少，所能支持的传输块大小的种数也随之减少。一个极端情况，当物理资源单元的起点是N_RU-1时，即起点是最后一个物理资源单元时，那么仅可以占用一个物理资源单元，这时必然只支持少数几种传输块大小，仅是传输块大小集合中很小的一部分。从图4中可以看出，该矩阵类似于一个对角阵，有一半的元素为0。这样，如果将物理资源单元起始位置信息和传输块大小信息进行联合编码，至少可以节省1个比特。Referring to Figure 4, the rows of the matrix represent the numbers of all transport block sizes supported in the system; the columns represent the starting position numbers of different physical resource units, starting from the starting point of a certain physical resource unit, and can be mapped according to the number of physical resource units that may be occupied The number of transport block sizes that can be supported. If starting from a certain starting point, a certain transmission block size can be supported, the corresponding element in the matrix is set to "1", otherwise it is set to "0". It can be seen from Fig. 4 that, as the starting point of the physical resource unit gradually moves backward, the number of physical resource units that can be occupied from this starting point gradually decreases, and the number of types of transport block sizes that can be supported also decreases accordingly. In an extreme case, when the starting point of the physical resource unit is N_RU -1, that is, when the starting point is the last physical resource unit, then only one physical resource unit can be occupied. At this time, only a few transmission block sizes must be supported, only A very small subset of the set of transport block sizes. As can be seen from Figure 4, the matrix is similar to a diagonal matrix, half of the elements are 0. In this way, at least one bit can be saved if the information about the starting position of the physical resource unit and the information about the size of the transport block are jointly encoded.

下面用一个具体实施进行说明：Let's illustrate with a specific implementation:

设系统的物理资源单元数量是48，支持的传输块大小数量为100，调制方式为4种，粗粒度的编码格式是8种，现在需要调度6个用户，则采用现有技术方案需要的信令比特数计算如下：Assuming that the number of physical resource units of the system is 48, the number of supported transport block sizes is 100, the modulation modes are 4 types, and the coarse-grained coding formats are 8 types. Now 6 users need to be scheduled, and the signal required by the existing technical solution is used. Let the number of bits be calculated as follows:

分配给UE的物理资源单元的起始位置和占用的物理资源单元数量信息需要的比特数通过下式(5)计算：The number of bits required for the starting position of the physical resource unit allocated to the UE and the number of occupied physical resource units is calculated by the following formula (5):

           [log₂48]+([log₂48]-1)＝11(比特)      (5)[log₂ 48]+([log₂ 48]-1)=11 (bits) (5)

传输块大小信息需要的比特数通过下式(6)计算：The number of bits required to transmit the block size information is calculated by the following equation (6):

           [log₂100]＝7(比特)                   (6)[log₂ 100] = 7 (bits) (6)

调制格式信息需要的比特数通过下式(7)计算：The number of bits required for the modulation format information is calculated by the following formula (7):

           [log₂4]＝2(比特)                     (7)[log₂ 4] = 2 (bits) (7)

则调度信令信息所需总的信令比特数为：11+7+2＝20(比特)。Then the total number of signaling bits required for the scheduling signaling information is: 11+7+2=20 (bits).

采用本发明上述方法需要的信令比特数计算如下：The number of signaling bits required by the above-mentioned method of the present invention is calculated as follows:

分配给UE的物理资源单元的起始位置信息需要的比特数通过下式(8)计算：The number of bits required for the starting position information of the physical resource unit allocated to the UE is calculated by the following formula (8):

           [log₂48]＝6(比特)                    (8)[log₂ 48] = 6 (bits) (8)

传输块大小信息需要的比特数通过下式(9)计算：The number of bits required to transmit the block size information is calculated by the following equation (9):

           [log₂100]-1＝6(比特)                 (9)[log₂ 100]-1=6 (bits) (9)

调制格式信息需要的比特数通过下式(10)计算：The number of bits required for the modulation format information is calculated by the following formula (10):

           [log₂4]＝2(比特)              (10)[log₂ 4] = 2 (bits) (10)

编码格式信息所需比特数通过下式(11)计算：The number of bits required for encoding format information is calculated by the following formula (11):

           [1og₂8]＝3(比特)              (11)[log₂ 8] = 3 (bits) (11)

调制信令所需总的信令比特数为：6+6+2+3＝17(比特)。The total number of signaling bits required for modulation signaling is: 6+6+2+3=17 (bits).

由此可知，采用本发明减少了调度信令信息所需总的信令比特数。It can be seen that the total number of signaling bits required for scheduling signaling information is reduced by adopting the present invention.

在本发明的上述方法中，一旦传输块大小确定之后，那么可选的调制格式和编码格式范围也会变小，但是需要具体的传输块大小取值集合和具体的调制编码格式的集合以及每种传输块大小与调制格式编码格式信息的对应关系才能推出比特的减少情况，而这些信息会因为系统的不同而不同。上述计算过程中，没有把具体比特数量的减少计算进去；如果仅考虑可选的调制格式和编码格式，需要的比特数量可能会进一步减少。In the above method of the present invention, once the transport block size is determined, the range of optional modulation formats and coding formats will also become smaller, but a specific set of transport block size values and a specific set of modulation and coding formats and each The bit reduction can only be deduced from the correspondence between the transport block size and the coding format information of the modulation format, and this information will vary from system to system. In the above calculation process, the reduction of the specific number of bits is not included in the calculation; if only optional modulation formats and coding formats are considered, the required number of bits may be further reduced.

实施例4：Example 4:

下发给UE的调度信令信息至少包含UE标识信息、传输块大小信息、分配给UE的物理资源单元的位置信息、调制信息和编码信息；其中，对传输块大小信息和分配给UE的物理资源单元的位置信息进行联合编码；并对所述调制信息和编码信息进行联合编码，其余信息独立编码。The scheduling signaling information issued to the UE includes at least UE identification information, transport block size information, location information of physical resource units allocated to the UE, modulation information, and coding information; among them, the transport block size information and the physical resource unit allocated to the UE The position information of the resource unit is jointly encoded; and the modulation information and the encoding information are jointly encoded, and the remaining information is independently encoded.

实施例4与实施例3的区别在于，除了对传输块大小信息和分配给UE的物理资源单元的位置信息进行联合编码，还结合实施2的方法，对所述调制信息和编码信息进行联合编码。The difference betweenembodiment 4 andembodiment 3 is that, in addition to jointly encoding the transport block size information and the location information of the physical resource unit allocated to the UE, the modulation information and the encoding information are also jointly encoded in combination with the method ofimplementation 2 .

实施例5：Example 5:

下发给UE的调度信令信息至少包含UE标识信息、传输块大小信息、分配给UE的物理资源单元的位置信息、调制信息和编码信息；其中，对传输块大小信息、分配给UE的物理资源单元的位置信息、调制信息和编码信息进行联合编码，其余信息独立编码。The scheduling signaling information issued to the UE includes at least UE identification information, transport block size information, location information of physical resource units allocated to the UE, modulation information, and coding information; among them, the transport block size information, physical resource units allocated to the UE The location information, modulation information and coding information of the resource unit are jointly coded, and other information is coded independently.

由实施例4可知，传输块大小信息和分配物理资源单元的位置信息进行联合编码后可以节省信令开销，再进一步地，根据已确定的信息，其对应的调制信息和编码信息的可选范围也会小于等于原始集合，所以，所有这些调度信息统一进行联合编码，可以进一步减少信令的比特开销。It can be seen fromEmbodiment 4 that the joint encoding of the transport block size information and the location information of the allocated physical resource units can save signaling overhead, and further, according to the determined information, the corresponding modulation information and encoding information can be selected. will also be less than or equal to the original set, so all these scheduling information are uniformly encoded jointly, which can further reduce the bit overhead of signaling.

类似于图3，矩阵的行表示系统中的调制编码方式(此处和实施例2类似，指调制方式和粗粒度的编码码率信息联合考虑)；列表示系统中支持的所有传输块大小的编号，根据传输块大小可以映射出可以采用的调制编码方式种数。如果对应于某个传输块大小，能支持某种调制编码格式，则矩阵中对应的该元素置为“1”，否则置为“0”。图5仅是一个示意图，对应于某个传输块大小，只能支持一组调制编码格式，可能小于原始集合。这样，如果结合传输块大小信息和调制编码格式信息进行联合编码，也可以节省信令开销。所以本实施例提出在实施例4的基础上进一步联合编码。Similar to Figure 3, the rows of the matrix represent the modulation and coding schemes in the system (similar toEmbodiment 2 here, referring to the joint consideration of the modulation scheme and the coarse-grained code rate information); the columns represent all transport block sizes supported in the system Number, according to the size of the transport block, the number of modulation and coding methods that can be used can be mapped. If corresponding to a certain transport block size, a certain modulation and coding format can be supported, the corresponding element in the matrix is set to "1", otherwise it is set to "0". Figure 5 is only a schematic diagram, corresponding to a certain transport block size, only one set of modulation and coding formats can be supported, which may be smaller than the original set. In this way, if joint coding is performed in combination with the transport block size information and the modulation and coding format information, signaling overhead can also be saved. Therefore, this embodiment proposes further joint coding on the basis ofEmbodiment 4.

上述实施例2、3、4、5中，UE接收到调度信令后，解析出对应的调度信息；当调度信息为指示UE的下行调度信息时，根据解析出的调度信息计算出基站采用的实际编码码率，确定出发送给自己的数据块所占用的物理资源单元数量，进行解调制和解码处理；In the above-mentionedembodiments 2, 3, 4, and 5, after receiving the scheduling signaling, the UE parses out the corresponding scheduling information; when the scheduling information indicates the downlink scheduling information of the UE, calculates the scheduling information adopted by the base station according to the parsed scheduling information.

式中，N_RUx表示计算出的物理资源单元数量，N_TBSx表示传输块大小对应的原始比特数量，C表示解析出的编码码率，N_Band表示每个物理资源单元可以承载的调制符号数量，M表示调制阶数；In the formula, N_RUx represents the calculated number of physical resource units,_NTBSx represents the number of original bits corresponding to the transport block size, C represents the parsed code rate, N_Band represents the number of modulation symbols that each physical resource unit can carry, M represents the modulation order;

实施例6与实施例1的区别在于在调度信令信息中增加了调制信息。通过调度信令信息的信息项根据式(1)可以计算出精确的编码码率信息。The difference betweenEmbodiment 6 andEmbodiment 1 is that modulation information is added to the scheduling signaling information. Accurate coding rate information can be calculated according to the formula (1) through the information items of the scheduling signaling information.
