Description

Method for allocating uplink resources, method for feedback signaling and corresponding device

Technical field

The present invention relates to the field of communications technologies, and in particular, to a method for allocating uplink resources, a method for feedback signaling, and a corresponding device.

Background technique

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 the terminal sends an SR to the radio access network (RAN) device, and the RAN device informs the RAN device that the uplink information needs to be transmitted, and the RAN device allocates the uplink resource to the terminal.

When the SR mechanism is used for the signaling interaction between the RAN device and the terminal, the signaling interaction process has a large 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 the signaling 1 to the terminal (S101). After receiving the signaling 1, the terminal often needs to provide feedback for the signaling 1. For example, the terminal sends the feedback signaling 2 for the signaling 1 to the RAN device (S104). . According to the existing uplink scheduling mechanism, the terminal needs to send the SR to the RAN device before sending the feedback signaling 2 to the RAN device (S102), and the RAN device detects that the SR sent by the terminal allocates uplink resources to the terminal, and sends the uplink to the terminal. The resource authorization (S103), the terminal can send the feedback signaling 2 according to the uplink resource allocated by the RAN device.

It can be seen that the uplink scheduling request may generate a transmission delay, and the SR transmission may fail due to a poor air interface environment or a terminal failure, and the terminal may not obtain an uplink resource that sends feedback signaling to the RAN device, resulting in the RAN. The failure of signaling interaction between the device and the terminal.

detailed description

The technical solutions of the present invention are described in detail below with reference to the accompanying drawings and specific embodiments. It is understood that the specific features of the embodiments and the embodiments of the present invention are the detailed description of the technical solutions of the present invention, and are not limited to the technical solutions of the present invention. In the case of no conflict, the embodiment of the present invention The technical features in the embodiments can be combined with each other.

As already mentioned in the background section, there is a problem that the delay is large in the existing signaling interaction process. In order to solve the problem, an uplink pre-scheduling mechanism in the data transmission process may be adopted, that is, the RAN device allocates uplink resources to the terminal in advance. An implementation manner may be that the RAN device allocates uplink resources to the terminal according to a fixed period, and the allocated uplink resources are often fixed and large enough to ensure that the terminal can successfully send uplink data. However, this method is often used to waste resources during the signaling interaction process. For example, the uplink resources allocated to a terminal are usually much larger than the uplink resources they actually need.

Therefore, in the embodiment of the present invention, a method for allocating uplink resources is proposed for the characteristics of the signaling interaction process. When the RAN device needs to send the signaling to the terminal, the size of the feedback signaling of the signaling is determined, and the uplink resource authorization that meets the size requirement of the feedback signaling is sent to the terminal, so that the terminal can send the feedback signal in time. Let reduce the delay in the signaling interaction process. The authorization of the uplink resource is performed by the RAN device and does not need to wait for the SR sent by the terminal. Therefore, the signaling interaction failure caused by the failure of the SR transmission can be avoided.

The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

First, some of the terms are explained to be understood by those skilled in the art.

1) A terminal, also known as a user equipment (UE), is a device that provides voice and/or data connectivity to a user, for example, a handheld device with wireless connectivity, connected to a wireless modem solution. Other processing devices of the decoder, etc.

2) The RAN device is a device that accesses the UE to the wireless network, including but not limited to: an evolved Node B (eNB), a radio network controller (RNC), and a Node B ( Node B, NB), Base Station Controller (BSC), Base Transceiver Station (BTS), Home Base Station (for example, Home evolved NodeB, or Home Node B, HNB), Wifi access point (Access Point, AP), etc. In addition, the RAN device may also be a BaseBand Unit (BBU), a cell communication device, a relay device, or the like.

Referring to FIG. 2, a signaling interaction between a RAN device and a terminal according to an embodiment of the present invention is provided. A schematic diagram of the process, the signaling interaction process includes the following steps:

S201: The RAN device generates signaling sent to the terminal.

S202: The RAN device determines the size of the feedback signaling of the signaling.

S203: The RAN device allocates an uplink resource to the terminal according to the size of the feedback signaling, and the allocated uplink resource can at least carry the feedback signaling.

S204: The RAN device sends the foregoing signaling and uplink resource authorization to the terminal, where the uplink resource authorization includes information about the uplink resource allocated by the RAN device to the terminal.

S205: The terminal sends feedback signaling to the RAN by using the RAN device for the allocated uplink resource.

In this embodiment, when generating the signaling sent to the terminal, the RAN device predetermines the size of the feedback signaling of the signaling, and actively allocates uplink resources to the terminal according to the size of the feedback signaling, so that the terminal can Feedback is provided on the allocated uplink resources in a timely manner. Therefore, the RAN device does not need to wait for the SR of the terminal to allocate resources to the terminal, which greatly reduces the delay of signaling feedback. Moreover, since the allocation of the uplink resources takes into account the size of the feedback signaling, the allocated resources are more reasonable and the waste of resources is avoided.

The signaling interaction process between the RAN device and the terminal is different from the data transmission process, and the content of the signaling is agreed. Therefore, when the RAN device determines that a certain signaling is to be sent, the content of the feedback signaling can be known in advance. Therefore, the size of the uplink resource can be actively allocated according to the size of the feedback signaling estimated in advance, thereby improving the signaling interaction efficiency.

Taking the Long Term Evolution (LTE) communication system as an example, the above method is applied in the Radio Resource Control (RRC) connection reconfiguration process as follows:

Please refer to FIG. 3 , which is a schematic diagram of a signaling interaction process in an RRC connection reconfiguration process according to an embodiment of the present invention. As shown in Figure 3, the following steps are included:

S301: The RAN device determines that the RRC connection reconfiguration (RRC Connection Reconfiguration) signaling needs to be sent to the terminal, where the RAN device is an Evolved Universal Terrestrial Radio Access Network (EUTRAN) device, and the terminal is a UE.

The RRC connection reconfiguration process may be generated in the process of measurement, handover, secondary cell configuration, discontinuous reception (DRX) configuration, and random access channel (RACH) configuration. Therefore, the above resource allocation is adopted. Methods can greatly improve the efficiency of these processes.

S302: The RAN device determines a size of the feedback signaling of the RRC connection reconfiguration signaling, where the feedback signaling of the RRC connection reconfiguration signaling is RRC connection reconfiguration complete signaling. The contents of various signaling are defined in the 3GPP protocol 36.331. For example, the contents of the respective feedback signaling are given in the message definitions of the 6.2.2 chapter of 3GPP TS 36.331 V12.5.0. The definition of the RRC connection reconfiguration complete signaling is included, so the base station can estimate the size of the feedback signaling according to the content of the feedback signaling.

The following is the definition of the content of the RRC connection reconfiguration complete signaling in the protocol. Specifically, the size of the RRC connection reconfiguration complete signaling may be determined according to the following content. Specifically include:

For the meaning of the above code, please refer to the prior art, which is not described in detail in the embodiments of the present invention.

S303: The RAN device allocates an uplink resource to the terminal according to the size of the RRC connection reconfiguration complete signaling, and the allocated uplink resource may at least carry the RRC connection reconfiguration complete signaling.

S304: The RAN device sends the RRC connection reconfiguration signaling and the allocated uplink resource authorization to the terminal, where the uplink resource authorization includes information about the uplink resource allocated by the RAN device for the terminal.

S305: The terminal sends an RRC connection reconfiguration complete signaling to the RAN by using the RAN device for the allocated uplink resource.

The process of the RRC connection reconfiguration is described as an example. For the failed process, the resource allocation process of the feedback signaling is similar, and details are not described herein.

The above is only an example and is not intended to limit the invention. The method provided by the embodiment of the present invention may also be used in other signaling interaction processes, such as an RRC connection setup, an RRC connection re-establisment, and the like, and the feedback signaling is completed by the RRC. (RRCConnectionSetupComplete) A message such as RRC Connection Reestablishment Complete (RRCConnectionReestablishmentComplete). The method for allocating uplink resources in the signaling interaction process can be obtained by those skilled in the art according to the foregoing embodiments.

It should be noted that the RAN device determines that the size of the feedback signaling can be directly calculated according to the content of the feedback signaling when needed; or can be pre-computed and stored in the RAN device in a corresponding relationship, so as to directly query when needed. obtain. The corresponding relationship may be a correspondence between the signaling and the size of the feedback signaling, or may be a correspondence between the size of the feedback signaling and the feedback signaling.

In addition, the uplink resource allocated by the RAN device for the terminal may be equal to the resource required for the feedback signaling; or may be greater than the resource required for the feedback signaling, for example, may be set larger than the resources required for the feedback signaling. Resource value.

In addition, the RAN device may send an uplink resource authorization while transmitting signaling, or may send an uplink resource authorization after sending the signaling, and the present invention does not impose any limitation.

Please refer to FIG. 4 , which is a flowchart of a method for allocating uplink resources according to an embodiment of the present invention. As shown in FIG. 4 , the method includes the following steps:

S401: The RAN device generates signaling sent to the terminal.

S402: The RAN device determines the size of the feedback signaling of the signaling.

S403: The RAN device allocates an uplink resource to the terminal according to the size of the feedback signaling, and the allocated uplink resource can at least carry the feedback signaling.

S404: The RAN device sends the signaling and uplink resource authorization to the terminal, where the uplink resource authorization includes information about an uplink resource allocated by the RAN device for the terminal.

Specifically, the RAN device sends signaling to the terminal in the process of establishing a connection with the terminal, managing the connection with the terminal, and deleting the connection, so that the RAN device and the terminal can mutually interact to implement related information required for the foregoing operation, and ensure wireless. The communication network works in an orderly manner. When the step S401 is specifically implemented, the signaling may be generated by a Central Processing Unit (CPU) of the RAN device, or may be generated by a coprocessor or a communication module responsible for generating a communication command. As described above, the specific type of signaling generated by the RAN device in the embodiment of the present invention is not limited.

When implemented in step S402, the manner in which the RAN device determines the size of the feedback signaling of the signaling includes, but is not limited to:

In the first manner, the feedback signaling of the signaling is determined; and the size of the feedback signaling is determined according to the content of the feedback signaling.

Specifically, in the determined communication protocol, the feedback signaling of the signaling and the content of the feedback signaling are agreed upon. Therefore, when the RAN device generates the signaling sent to the terminal, the RAN device can determine the feedback signal of the signaling. Order, and the content of the feedback signaling (for example, what information to include in the feedback signaling, how many digits each message is used, how many bits each information needs to occupy, etc.), in determining the feedback signaling After the content, the size of the feedback signaling can be determined.

Mode 2, the RAN device stores the correspondence between the signaling and the size of the feedback signaling (the following content) The RAN device queries the first correspondence and obtains the size of the signaling signaling of the signaling.

Specifically, since the 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 correspondence, where the first correspondence includes the correspondence between the signaling and the size of the feedback signaling, and the RAN device only needs to query the first correspondence to determine step S401. The size of the feedback signaling generated in the signaling.

In a third mode, the RAN device stores a correspondence between the size of the feedback signaling and the feedback signaling (referred to as a second correspondence in the following content), and the RAN device first determines the signaling signaling of the signaling, and then queries the second correspondence. The size of the feedback signaling for signaling is obtained.

Specifically, since the content of each feedback signaling is agreed upon, the size of the feedback signaling is determined. In the embodiment of the present invention, the RAN device device may pre-store a second correspondence, where the second correspondence includes a correspondence between the feedback signaling and its size. After generating the signaling, the RAN device may determine the signaling 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.

In the foregoing manners 2 and 3, the first correspondence and the second correspondence may be stored in the cloud (server). When the step S402 is performed, the RAN device obtains the correspondence from the cloud, and determines the feedback signaling according to the obtained correspondence. the size of.

In step S403, since the size of the feedback signaling has been determined, the transmission resource required for the feedback signaling may also be determined, and the RAN device allocates an uplink resource that can carry the feedback signaling to the terminal. In a specific implementation, the RAN device may allocate, to the terminal, an uplink resource that is consistent with the size of the feedback signaling determined in step S402, that is, the uplink resource allocated by the RAN device for the terminal is equal to the resource required for the feedback signaling, so as to save as much as possible. Transfer resources to improve resource utilization.

In an actual situation, in order to ensure that the uplink resource allocated to the terminal can carry the feedback signaling that the terminal needs to send, the uplink resource allocated to the terminal may be slightly more than the actual transmission resource required by the feedback signaling size determined in step S402. That is, the RAN device allocates a resource value that is greater for the uplink resource allocated by the terminal than the resource required for the feedback signaling, and implements a certain fault tolerance mechanism to be actually sent at the terminal. When the size of the feedback signaling is larger than the size of the feedback signaling determined in step S402, the uplink resource allocated for the terminal can carry the feedback signaling that the terminal needs to send.

In addition, even if the size of the feedback signaling actually sent by the terminal is different from the size of the feedback signaling determined in step S402, the difference between the two is small. Therefore, the foregoing set resource value may be a smaller value. To save transmission resources.

In step S404, the RAN device sends signaling and uplink resource authorization to the terminal, including the following two implementation manners:

First, when the RAN device sends signaling to the terminal, the RAN device sends an uplink resource authorization to the terminal. Specifically, the RAN device sends signaling and uplink resource authorization to the terminal at the same time to shorten the time of signaling interaction.

Second, the RAN device sends an uplink resource grant to the terminal within a set duration after signaling to the terminal. Specifically, the RAN device first sends signaling to the terminal, and after the set duration, sends an uplink resource grant to the terminal, because it takes time for the terminal to parse the received signaling and generate feedback signaling, if the foregoing setting is The duration is less than the time spent by the terminal, or is equivalent to the time spent by the terminal, and the delay effect on the signaling interaction between the RAN device and the terminal can be ignored.

In the foregoing method for allocating an uplink resource, the RAN device can determine the size of the feedback signaling of the signaling when generating an instruction sent to the terminal, and actively allocate the uplink capable of carrying the feedback signaling to the terminal. The resource enables the terminal to directly send feedback signaling to the RAN device according to the allocated uplink resource, which reduces the delay of signaling interaction between the RAN device and the terminal.

In addition, in the method for allocating uplink resources, the capacity of the uplink resource allocated by the RAN device for the terminal is adapted to the capacity of the feedback command returned by the terminal to the RAN device, thereby avoiding allocating a fixed capacity uplink to the terminal. When the resource is used, the capacity of the allocated uplink resource is much larger than the actual waste transmission requirement of the terminal return feedback instruction.

Based on the same inventive concept, the embodiment of the present invention further provides a method for feedback signaling. Referring to FIG. 5, the method includes the following steps:

S501: The terminal receives signaling sent by a radio access network (RAN) device.

S502: The terminal receives an uplink resource authorization sent by the RAN device, where the uplink resource authorization includes the RAN. The information about the uplink resource allocated by the device for the terminal, and the uplink resource is a resource that the RAN device can allocate at least the feedback signaling according to the size of the feedback signaling of the signaling.

S503: The terminal sends feedback signaling to the uplink resource allocated by the terminal by using the RAN device.

The step S501 and the step S502 may be performed simultaneously, or the step S502 may be performed after the step S501 is performed.

Optionally, in the embodiment of the present invention, the uplink resource allocated by the RAN device to the terminal is equal to the resource required for the feedback signaling, or the resource value set larger than the resource required for the feedback signaling.
