本发明涉及通信技术领域，特别涉及一种分配上行资源的方法、反馈信令的方法及对应装置。The present invention relates to the field of communication technology, in particular to a method for allocating uplink resources, a method for feedback signaling and a corresponding device.
在无线通信领域，为了节约传输资源，通过上行调度请求(Scheduling Request，SR)机制来分配上行资源。具体的，只有终端向无线接入网(Radio Access Network，RAN)设备发送SR，告知RAN设备自己有上行信息需要传输，RAN设备才会为终端分配上行资源。In the field of wireless communication, in order to save transmission resources, uplink resources are allocated through an uplink scheduling request (Scheduling Request, SR) mechanism. Specifically, only when the terminal sends an SR to the radio access network (Radio Access Network, RAN) device to inform the RAN device that it has uplink information to transmit, the RAN device will allocate uplink resources for the terminal.
该SR机制用于RAN设备与终端之间的信令交互时，常常出现信令交互过程时延较大的情况，甚至会信令交互失败的场景。参照图1，其为一种现有的RAN设备与终端之间的信令交互示意图。RAN设备向终端发送信令1(S101)，终端收到该信令1后，往往需要针对该信令1进行反馈，例如，终端向RAN设备发送针对信令1的反馈信令2(S104)。根据现有上行调度机制，终端在向RAN设备发送反馈信令2之前，需要向RAN设备发送SR(S102)，RAN设备检测到终端发送的SR才会为终端分配上行资源，并向终端发送上行资源授权(S103)，终端才能根据RAN设备分配的上行资源发送反馈信令2。When the SR mechanism is used for signaling interaction between the RAN device and the terminal, it often occurs that the signaling interaction process has a long delay, and even the signaling interaction fails. Referring to FIG. 1 , it is a schematic diagram of signaling interaction between an existing RAN device and a terminal. The RAN device sends signaling 1 to the terminal (S101), and after receiving the signaling 1, the terminal often needs to give feedback on the signaling 1, for example, the terminal sends a feedback signaling 2 on the signaling 1 to the RAN device (S104) . According to the existing uplink scheduling mechanism, the terminal needs to send an SR to the RAN device (S102) before sending the feedback signaling 2 to the RAN device. The RAN device will only allocate uplink resources for the terminal after detecting the SR sent by the terminal, and send an uplink signal to the terminal. Resource authorization (S103), the terminal can send feedback signaling 2 according to the uplink resource allocated by the RAN device.
可见，上行调度请求的方式会产生传输时延，而且还可能会因为空口环境较差或终端故障等原因，导致SR传输失败，进而终端无法获得向RAN设备发送反馈信令的上行资源，导致RAN设备与终端间信令交互的失败。It can be seen that the way of uplink scheduling request will cause transmission delay, and may also cause SR transmission failure due to reasons such as poor air interface environment or terminal failure, and then the terminal cannot obtain uplink resources to send feedback signaling to RAN equipment, resulting in RAN The signaling interaction between the device and the terminal failed.

下面通过附图以及具体实施例对本发明技术方案做详细的说明，应当理解本发明实施例以及实施例中的具体特征是对本发明技术方案的详细的说明，而不是对本发明技术方案的限定，在不冲突的情况下，本发明实施例以及实施例中的技术特征可以相互组合。The technical solutions of the present invention will be described in detail below through the accompanying drawings and specific examples. It should be understood that the embodiments of the present invention and the specific features in the examples are detailed descriptions of the technical solutions of the present invention, rather than limitations to the technical solutions of the present invention. In the case of no conflict, the embodiment of the present invention usesAnd the technical features in the embodiments can be combined with each other.
在背景技术部分已经提及，现有的信令交互过程中，存在时延较大的问题。为了解决该问题可以采用数据传输过程中的上行预调度的机制，即RAN设备提前为终端分配上行资源。一种实现方式可以为RAN设备按照固定的周期为终端分配上行资源，该分配的上行资源往往是固定大小且足够大的，以保证终端能够顺利地发送上行数据。然而这种方式用于信令交互过程中往往会造成资源浪费。例如，为终端分配的上行资源通常会比其实际需求的上行资源大很多。As mentioned in the background section, there is a problem of long delay in the existing signaling interaction process. In order to solve this problem, an uplink pre-scheduling mechanism during data transmission can be used, that is, the RAN device allocates uplink resources for the terminal in advance. An implementation manner may be that the RAN device allocates uplink resources to the terminal at a fixed period, and the allocated uplink resources are usually of a fixed size and large enough to ensure that the terminal can smoothly send uplink data. However, when this method is used in the signaling interaction process, resources are often wasted. For example, the uplink resource allocated to the terminal is usually much larger than the uplink resource actually required by it.
因此，本发明实施例针对信令交互过程的特点，提出一种分配上行资源的方法。在RAN设备有信令需要发送给终端时，便确定出该信令的反馈信令的大小，且将符合该反馈信令的大小要求的上行资源授权发送给终端，以便终端可以及时发送反馈信令，减少信令交互过程中的时延。且该上行资源的授权是RAN设备主动进行的，不需要等待终端发送的SR，因此，可以避免因SR传输失败导致的信令交互失败。Therefore, the embodiment of the present invention proposes a method for allocating uplink resources according to the characteristics of the signaling interaction process. When the RAN device has a signaling that needs to be sent to the terminal, it determines the size of the feedback signaling of the signaling, and sends the uplink resource authorization that meets the size requirement of the feedback signaling to the terminal, so that the terminal can send the feedback signal in time To reduce the delay in the signaling interaction process. Moreover, the authorization of the uplink resource is actively performed by the RAN device without waiting for the SR sent by the terminal. Therefore, the signaling interaction failure caused by the SR transmission failure can be avoided.
下面结合附图对本发明的实施例进行详细描述。Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
首先，对部分用语进行解释说明，以便于本领域技术人员理解。First, some terms are explained to facilitate the understanding of those skilled in the art.
1)、终端，又称之为用户设备(user equipment，UE)，是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、连接到无线调制解调译码器的其他处理设备等。1), terminal, also known as user equipment (UE), is a device that provides voice and/or data connectivity to users, for example, a handheld device with wireless connection function, connected to a wireless modem Other processing equipment of the codec, etc.
2)、RAN设备是一种将UE接入到无线网络的设备，包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(Base Station Controller，BSC)、基站收发台(Base Transceiver Station,BTS)、家庭基站(例如，Home evolved NodeB，或，Home Node B，HNB)、Wifi接入点(Access Point，AP)等。此外，该RAN设备也可以是基带单元(BaseBand Unit，BBU)、小区通信设备、中继设备等。2), RAN device is a device that connects UE to a wireless network, including but not limited to: evolved Node B (evolved Node B, eNB), radio network controller (radio network controller, RNC), Node B ( Node B, NB), base station controller (Base Station Controller, BSC), base transceiver station (Base Transceiver Station, BTS), home base station (for example, Home evolved NodeB, or, Home Node B, HNB), Wifi access point (Access Point, AP) and so on. In addition, the RAN device may also be a baseband unit (BaseBand Unit, BBU), a cell communication device, a relay device, and the like.
参照图2，为本发明实施例提供的一种RAN设备与终端之间的信令交互过程的示意图，该信令交互过程包括如下步骤：Referring to Figure 2, it is a signaling interaction between a RAN device and a terminal provided by an embodiment of the present inventionA schematic diagram of the process, the signaling interaction process includes the following steps:
S201：RAN设备生成向终端发送的信令。S201: The RAN device generates signaling to be sent to the terminal.
S202：RAN设备确定该信令的反馈信令的大小。S202: The RAN device determines the size of the feedback signaling of the signaling.
S203：RAN设备根据反馈信令的大小，为终端分配上行资源，且分配的上行资源至少可以承载该反馈信令。S203: The RAN device allocates uplink resources to the terminal according to the size of the feedback signaling, and the allocated uplink resources can at least bear the feedback signaling.
S204：RAN设备向终端发送以上信令和上行资源授权，该上行资源授权包括RAN设备为终端分配的上行资源的信息。S204: The RAN device sends the above signaling and an uplink resource grant to the terminal, where the uplink resource grant includes information about uplink resources allocated by the RAN device to the terminal.
S205：终端利用RAN设备为其分配的上行资源向RAN发送反馈信令。S205: The terminal sends feedback signaling to the RAN by using the uplink resource allocated to it by the RAN device.
在本实施例中，RAN设备在生成向终端发送的信令时，便预先确定该信令的反馈信令的大小，并根据反馈信令的大小，主动为终端分配上行资源，使得终端可以在所分配的上行资源上及时进行反馈。由此，RAN设备无需再等待终端的SR后再为终端分配资源，极大的减少了信令反馈的时延。且由于上行资源的分配考虑到了反馈信令的大小，因此所分配的资源更加合理，避免了资源的浪费。In this embodiment, when the RAN device generates the signaling to be sent to the terminal, it predetermines the size of the feedback signaling of the signaling, and actively allocates uplink resources for the terminal according to the size of the feedback signaling, so that the terminal can Feedback is performed in a timely manner on the allocated uplink resources. Therefore, the RAN device does not need to wait for the SR of the terminal before allocating resources to the terminal, which greatly reduces the delay of signaling feedback. Moreover, since the size of the feedback signaling is taken into account in the allocation of uplink resources, the allocated resources are more reasonable and waste of resources is avoided.
RAN设备与终端之间的信令交互过程不同于数据传输过程，信令的内容是约定好的，因此当RAN设备确定了某个信令待发送时，其反馈信令的内容是可以预先知道的，因此可以根据其内容预先估计其大小，进而根据预先估计的反馈信令的大小来主动分配上行资源，提高信令交互效率。The signaling interaction process between the RAN device and the terminal is different from the data transmission process. The content of the signaling is agreed. Therefore, when the RAN device determines that a certain signaling is to be sent, the content of its feedback signaling can be known in advance. Therefore, its size can be pre-estimated according to its content, and then the uplink resources can be actively allocated according to the pre-estimated size of the feedback signaling, so as to improve the efficiency of signaling interaction.

For example, the content of the respective feedback signaling is given in the message definitions of chapter 6.2.2 of 3GPP TS 36.331V12.5.0. It includes the definition of the RRC connection reconfiguration completion signaling, so the base station can estimate the size of the feedback signaling according to the content of the feedback signaling.

S305：终端利用RAN设备为其分配的上行资源向RAN发送RRC连接重配置完成信令。S305: The terminal sends an RRC connection reconfiguration completion signaling to the RAN by using the uplink resource allocated to it by the RAN device.

需要说明的是，RAN设备确定反馈信令的大小可以在需要时直接根据反馈信令的内容计算得到；也可以预先计算好，以对应关系的方式存储于RAN设备中，以便在需要时直接查询获得。具体该对应关系可以是信令与其反馈信令的大小的对应关系；也可以是反馈信令与反馈信令的大小的对应关系。It should be noted that the size of the feedback signaling determined by the RAN device can be directly calculated according to the content of the feedback signaling when needed; it can also be pre-calculated and stored in the RAN device in a corresponding relationship, so that it can be directly queried when needed get. Specifically, the corresponding relationship may be a corresponding relationship between the size of the signaling and its feedback signaling; it may also be a corresponding relationship between the size of the feedback signaling and the feedback signaling.
另外，RAN设备为终端分配的上行资源可以等于反馈信令所需的资源；也可以大于反馈信令所需的资源，例如，可以比反馈信令所需的资源大设定的资源值。In addition, the uplink resources allocated by the RAN device to the terminal may be equal to the resources required by the feedback signaling, or may be greater than the resources required by the feedback signaling, for example, may be set larger than the resources required by the feedback signalingresource value.
此外，RAN设备可以在发送信令的同时发送上行资源授权，也可以在发送信令之后发送上行资源授权，本发明不做任何限制。In addition, the RAN device may send the uplink resource grant while sending the signaling, or may send the uplink resource grant after sending the signaling, which is not limited in the present invention.
请继续参考图4，其为本发明实施例提供的一种分配上行资源的方法的流程图，如图4所示，该方法包括如下步骤：Please continue to refer to FIG. 4, which is a flowchart of a method for allocating uplink resources provided by an embodiment of the present invention. As shown in FIG. 4, the method includes the following steps:
S401：RAN设备生成向终端发送的信令。S401: The RAN device generates signaling to be sent to the terminal.
S402：RAN设备确定该信令的反馈信令的大小。S402: The RAN device determines the size of the feedback signaling of the signaling.
S403：RAN设备根据反馈信令的大小，为终端分配上行资源，分配的上行资源至少可以承载该反馈信令。S403: The RAN device allocates uplink resources to the terminal according to the size of the feedback signaling, and the allocated uplink resources can at least bear the feedback signaling.
S404：RAN设备向终端发送该信令和上行资源授权，该上行资源授权包括RAN设备为终端分配的上行资源的信息。S404: The RAN device sends the signaling and an uplink resource grant to the terminal, where the uplink resource grant includes information about uplink resources allocated by the RAN device to the terminal.
具体的，RAN设备在与终端建立连接、管理与终端间的连接、删除连接等过程中，要向终端发送信令，使RAN设备与终端间能够交互实现上述操作所需的相关信息，保证无线通信网络有秩序地工作。步骤S401具体实施时，信令可以由RAN设备的中央处理器(Central Processing Unit，CPU)来生成，也可以由负责生成通信指令的协处理器或通信模块来生成。如前所述，本发明实施例中对RAN设备生成的信令的具体类型不予限定。Specifically, in the process of establishing a connection with the terminal, managing the connection with the terminal, and deleting the connection, the RAN device needs to send signaling to the terminal, so that the RAN device and the terminal can exchange relevant information required for the above operations, ensuring wireless The communication network works in an orderly manner. When step S401 is specifically implemented, the signaling may be generated by a central processing unit (Central Processing Unit, CPU) of the RAN device, or may be generated by a coprocessor or a communication module responsible for generating communication commands. As mentioned above, the specific type of signaling generated by the RAN device is not limited in the embodiment of the present invention.
在步骤S402实施时，RAN设备确定该信令的反馈信令的大小的方式，包括但不限于：When step S402 is implemented, the way for the RAN device to determine the size of the signaling feedback signaling includes but not limited to:
方式1，确定信令的反馈信令；根据反馈信令的内容，确定反馈信令的大小。Mode 1, determine the feedback signaling of the signaling; determine the size of the feedback signaling according to the content of the feedback signaling.
具体的，在确定的通信协议中，信令的反馈信令，以及反馈信令的内容是约定好的，因此，RAN设备在生成向终端发送的信令时，能够确定该信令的反馈信令，以及该反馈信令的内容(例如，该反馈信令要包含哪些信息、每项信息用多少进制表示，每项信息需要占用多少位数，等等)，在确定了反馈信令的内容后，即可确定出该反馈信令的大小。Specifically, in the determined communication protocol, the signaling feedback signaling and the content of the feedback signaling are agreed, therefore, when the RAN device generates the signaling to be sent to the terminal, it can determine the signaling feedback signaling command, and the content of the feedback signaling (for example, what information should the feedback signaling contain, how many bases are used for each information, how many digits each information needs to occupy, etc.), after determining the feedback signaling After the content, the size of the feedback signaling can be determined.
方式2，RAN设备存储有信令与反馈信令的大小的对应关系(以下内容中称为第一对应关系)，RAN设备查询该第一对应关系，获得信令的反馈信令的大小。Mode 2, the RAN device stores the corresponding relationship between the signaling and the size of the feedback signaling (the following contentis referred to as the first corresponding relationship in ), and the RAN device queries the first corresponding relationship to obtain the size of the feedback signaling of the signaling.
具体的，由于信令的反馈信令，以及反馈信令的内容是约定好的，因此，信令的反馈信令的大小是确定的。本发明实施例中，RAN设备可以预存有第一对应关系，该第一对应关系包含信令与反馈信令的大小的对应关系，RAN设备只需要查询该第一对应关系即可确定出步骤S401中生成的信令的反馈信令的大小。Specifically, since the feedback signaling of the signaling and the content of the feedback signaling are agreed upon, the size of the feedback signaling of the signaling is determined. In the embodiment of the present invention, the RAN device may pre-store the first corresponding relationship, the first corresponding relationship includes the corresponding relationship between the size of the signaling and the feedback signaling, and the RAN device only needs to query the first corresponding relationship to determine step S401 The size of the feedback signaling for the signaling generated in .
方式3，RAN设备存储有反馈信令与反馈信令的大小的对应关系(以下内容中称为第二对应关系)，RAN设备先确定信令的反馈信令，然后查询该第二对应关系，获得信令的反馈信令的大小。Mode 3, the RAN device stores the correspondence between the feedback signaling and the size of the feedback signaling (hereinafter referred to as the second correspondence), the RAN device first determines the feedback signaling of the signaling, and then queries the second correspondence, Get the size of the feedback signaling for the signaling.
具体的，由于每种反馈信令的内容是约定好的，因此，反馈信令的大小是确定的。本发明实施例中，RAN设备设备可以预存有第二对应关系，该第二对应关系包含反馈信令与其大小的对应关系。RAN设备在生成信令后，可以根据RAN设备当前运行所基于的通信协议确定出该信令的反馈信令，然后，查询该第二对应关系，确定出该反馈信令的大小。Specifically, since the content of each type of feedback signaling is agreed upon, the size of the feedback signaling is definite. In the embodiment of the present invention, the RAN device may pre-store a second correspondence, where the second correspondence includes the correspondence between the feedback signaling and its size. After generating the signaling, the RAN device may determine the feedback signaling of the signaling according to the communication protocol on which the RAN device is currently running, and then query the second correspondence to determine the size of the feedback signaling.
以上方式2、方式3中，第一对应关系、第二对应关系还可以保存在云端(服务器)，在执行步骤S402时，RAN设备从云端获取上述对应关系，依据获取的对应关系确定反馈信令的大小。In the above method 2 and method 3, the first corresponding relationship and the second corresponding relationship can also be stored in the cloud (server). When performing step S402, the RAN device obtains the above corresponding relationship from the cloud, and determines the feedback signaling according to the obtained corresponding relationship the size of.
步骤S403中，由于反馈信令的大小已经确定，则反馈信令所需的传输资源也是可以确定的，RAN设备为终端分配可以承载该反馈信令的上行资源。具体实施时，RAN设备可以为终端分配与步骤S402中确定出的反馈信令大小相一致的上行资源，即RAN设备为终端分配的上行资源等于反馈信令所需的资源，以尽可能的节约传输资源，提高资源利用率。In step S403, since the size of the feedback signaling has been determined, the transmission resources required for the feedback signaling can also be determined, and the RAN device allocates uplink resources capable of carrying the feedback signaling to the terminal. During specific implementation, the RAN device may allocate uplink resources to the terminal that are consistent with the size of the feedback signaling determined in step S402, that is, the uplink resources allocated by the RAN device to the terminal are equal to the resources required by the feedback signaling, so as to save resources as much as possible Transfer resources to improve resource utilization.
实际情况中，为了确保为终端分配的上行资源能够承载终端需要发送的反馈信令，为终端分配的上行资源可以比步骤S402中确定出的反馈信令大小实际所需的传输资源略多一点，即RAN设备为终端分配的上行资源比反馈信令所需的资源大设定的资源值，实现一定的容错机制，以在终端实际发送的反馈信令的大小大于步骤S402中确定出的反馈信令的大小时，为终端分配的上行资源能够承载终端需要发送的反馈信令。In actual situations, in order to ensure that the uplink resources allocated to the terminal can carry the feedback signaling that the terminal needs to send, the uplink resources allocated to the terminal may be slightly more than the transmission resources actually required by the size of the feedback signaling determined in step S402, That is, the uplink resource allocated by the RAN device to the terminal is larger than the resource value required for the feedback signaling, and a certain fault tolerance mechanism is implemented so that the resources actually sent by the terminalWhen the size of the feedback signaling is greater than the size of the feedback signaling determined in step S402, the uplink resource allocated to the terminal can bear the feedback signaling that the terminal needs to send.
另外，即使终端实际发送的反馈信令的大小与步骤S402中确定出的反馈信令的大小有差异，二者的差异也很小，因此，前述设定的资源值可以为一较小的值，以节约传输资源。In addition, even if there is a difference between the size of the feedback signaling actually sent by the terminal and the size of the feedback signaling determined in step S402, the difference between the two is very small. Therefore, the resource value set above can be a small value , to save transmission resources.
步骤S404中，RAN设备向终端发送信令和上行资源授权，包括以下两种实现方式：In step S404, the RAN device sends signaling and uplink resource authorization to the terminal, including the following two implementation methods:
其一，RAN设备在向终端发送信令时，向终端发送上行资源授权。具体的，RAN设备同时向终端发送信令以及上行资源授权，以缩短信令交互的时间。Firstly, the RAN device sends an uplink resource authorization to the terminal when sending signaling to the terminal. Specifically, the RAN device sends signaling and uplink resource authorization to the terminal at the same time, so as to shorten the time for signaling interaction.
其二，RAN设备在向终端发送信令后的设定时长内，向终端发送上行资源授权。具体的，RAN设备先向终端发送信令，在设定时长后，在向终端发送上行资源授权，这是因为终端解析接收的信令以及生成反馈信令均需要耗费时间，如果将前述设定时长小于终端耗费的以上时间，或与终端耗费的以上时间相当，对RAN设备与终端间信令交互的时延影响可以忽略。Second, the RAN device sends an uplink resource authorization to the terminal within a set period of time after sending the signaling to the terminal. Specifically, the RAN device first sends signaling to the terminal, and then sends an uplink resource grant to the terminal after setting the duration. This is because it takes time for the terminal to parse the received signaling and generate feedback signaling. If the aforementioned setting The duration is less than the above time spent by the terminal, or equivalent to the above time spent by the terminal, and the delay impact on the signaling interaction between the RAN device and the terminal can be ignored.
本发明实施例提供的上述分配上行资源的方法中，RAN设备在生成向终端发送的指令时，能够确定该信令的反馈信令的大小，并主动为终端分配能够承载该反馈信令的上行资源，使终端能够直接根据分配的上行资源向RAN设备发送反馈信令，减少了RAN设备与终端间信令交互的时延。In the above method for allocating uplink resources provided by the embodiments of the present invention, when the RAN device generates an instruction to be sent to the terminal, it can determine the size of the feedback signaling of the signaling, and actively allocate an uplink resource capable of carrying the feedback signaling to the terminal. Resources, so that the terminal can directly send feedback signaling to the RAN device according to the allocated uplink resources, reducing the delay of signaling interaction between the RAN device and the terminal.
不仅如此，本发明实施例提供的分配上行资源的方法中，RAN设备为终端分配的上行资源的容量，与终端向RAN设备返回的反馈指令的容量相适应，避免了为终端分配固定容量的上行资源时，分配的上行资源的容量比终端返回反馈指令实际的传输需求大很多导致的资源浪费情形。Not only that, in the method for allocating uplink resources provided by the embodiment of the present invention, the capacity of the uplink resource allocated by the RAN device to the terminal is adapted to the capacity of the feedback command returned by the terminal to the RAN device, avoiding the allocation of uplink resources with a fixed capacity for the terminal. When using resources, the capacity of the allocated uplink resources is much larger than the actual transmission demand of the feedback command returned by the terminal, resulting in waste of resources.
基于相同的发明构思，本发明实施例还提供一种反馈信令的方法，参照图5，该方法包括如下步骤：Based on the same inventive concept, an embodiment of the present invention also provides a method for feedback signaling. Referring to FIG. 5, the method includes the following steps:
S501：终端接收无线接入网(RAN)设备发送的信令。S501: The terminal receives signaling sent by a radio access network (RAN) device.
S502：终端接收RAN设备发送的上行资源授权，上行资源授权包括RAN设备为终端分配的上行资源的信息，上行资源为RAN设备在生成信令时，根据信令的反馈信令的大小为终端分配的至少可以承载反馈信令的资源。S502: The terminal receives the uplink resource grant sent by the RAN device, and the uplink resource grant includes the RANThe device is the information of the uplink resource allocated to the terminal, and the uplink resource is the resource allocated to the terminal according to the size of the feedback signal of the signaling when the RAN device generates the signaling and can at least bear the feedback signaling.
S503：终端利用RAN设备为终端分配的上行资源发送反馈信令。S503: The terminal sends feedback signaling using the uplink resources allocated by the RAN device for the terminal.
其中，步骤S501与步骤S502可以同时进行，也可以是在执行完步骤S501之后执行步骤S502。Wherein, step S501 and step S502 may be performed simultaneously, or step S502 may be performed after step S501 is performed.
可选的，本发明实施例中，RAN设备为终端分配的上行资源等于反馈信令所需的资源，或，比反馈信令所需的资源大设定的资源值。Optionally, in this embodiment of the present invention, the uplink resource allocated by the RAN device to the terminal is equal to the resource required by the feedback signaling, or is greater than the resource required by the feedback signaling by a set resource value.
可选的，本发明实施例中，终端同时收到信令和上行资源授权。Optionally, in this embodiment of the present invention, the terminal receives the signaling and the uplink resource grant at the same time.

本发明实施例中提供的一个或多个技术方案，至少具有如下技术效果或优点：One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages:
本发明实施例提供的分配上行资源的方法中，RAN设备在生成向终端发送的指令时，能够确定该信令的反馈信令的大小，并主动为终端分配能够承载该反馈信令的上行资源，使终端能够直接根据分配的上行资源向RAN设备发送反馈信令，减少了RAN设备与终端间信令交互的时延。不仅如此，本发明实施例提供的分配上行资源的方法中，RAN设备为终端分配的上行资源的容量，与终端向RAN设备返回的反馈指令的容量相适应，避免了为终端分配固定容量的上行资源时，分配的上行资源的容量比终端返回反馈指令实际的传输需求大很多导致的资源浪费情形。In the method for allocating uplink resources provided by the embodiments of the present invention, when the RAN device generates an instruction to be sent to the terminal, it can determine the size of the feedback signaling of the signaling, and actively allocate uplink resources capable of carrying the feedback signaling for the terminal , so that the terminal can directly report to the RAN device according to the allocated uplink resourcesSending feedback signaling reduces the delay of signaling interaction between the RAN device and the terminal. Not only that, in the method for allocating uplink resources provided by the embodiment of the present invention, the capacity of the uplink resource allocated by the RAN device to the terminal is adapted to the capacity of the feedback instruction returned by the terminal to the RAN device, avoiding the allocation of uplink resources with a fixed capacity for the terminal. When using resources, the capacity of the allocated uplink resources is much larger than the actual transmission demand of the feedback command returned by the terminal, resulting in waste of resources.
