In the existing implementation, the radio resource control RRC (Radio Resource Control Setup Request, RRCSetup request) requests to RRCSetup are serial processing, the base station Physical PHY (Physical) Layer sends the channel decoding result of the Physical uplink shared channel (Physical uplink shared channel, PUSCH) carrying the third message to the medium access control (Medium Access Control, MAC) Layer, after the MAC completes the decoding of the Transport Block (TB), the MAC sends the result to the Higher Layer (HL), HL decodes the RRCSetup request message first, after the decoding is successful, performs user index allocation, physical channel resource allocation, and group RRCSetup message and encodes, and then sends the result to the MAC for air interface scheduling, and the MAC sends the scheduling result to the PHY Layer for air interface transmission.

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The embodiment of the invention provides a NR system resource allocation method, network equipment, device, electronic equipment and storage medium, which are used for solving the technical problem that the time delay from an air interface of a third message to an air interface of a fourth message of a base station in the related technology is large.

The method and the device are based on the same application, and because the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repetition is not repeated.

Fig. 1 is a flow chart of a NR system resource allocation method according to an embodiment of the present invention, as shown in the figure, including:

s101, when the physical PHY layer detects the first message sent by the terminal device UE, the medium access control MAC layer allocates resources to the second message and the third message.

In the embodiment of the present invention, as shown in fig. 2, the radio resource control (Radio Resource Control, RRC layer) production cost of the UE establishes a connection request, rrcsetup request, and notifies the bottom layer to initiate random access, and the UE initiates a first message of a random access message on a Physical Random Access Channel (PRACH). And the base station PHY layer performs Preamble detection in the configuration time slot of the PRACH resource, and the PHY layer sends the detection result to the base station MAC. And the MAC receives the detection result of the first message, allocates a temporary user index, and allocates resources of the second message and a third message, wherein the third message carries the signaling content of the RRCSetup request.

Since the distance between the terminal and the network is uncertain due to the mobility of the terminal, if the terminal needs to connect to the NR system, maintenance management of uplink synchronization must be performed in real time. The purpose of the PRACH is to achieve uplink synchronization, establish a relationship with the uplink synchronization of the network and request the network to allocate dedicated resources to the terminal for normal service transmission. The first message is the actual content that the UE sends in the PRACH channel.

In the embodiment of the invention, the air interface time slot interval between the first message and the second message is smaller than or equal to the first preset time slot interval, and the air interface time slot interval between the second message and the third message is smaller than or equal to the second preset time slot interval. The first preset time slot interval and the second preset time slot interval are set in advance, and can be changed according to actual design requirements, and the method is not limited in any way. The air slot interval of the first message and the second message is generally smaller than the random access response window configured in the broadcast, and is generally configured to be 10ms, and the air slot interval of the second message and the third message should meet the minimum requirement specified by the protocol.

S102, under the condition that the MAC layer successfully allocates the resources of the second message and the third message, the resource allocation condition is sent to the PHY layer, and meanwhile, the higher layer HL is instructed to pre-configure the access resources for the UE to access the network according to the first message.

In the embodiment of the invention, the MAC layer allocates the resources of the second message and the third message, and the second message contains the resource allocation data of the third message, so that when the MAC layer successfully allocates the resources of the second message and the third message, the MAC layer groups the data content of the second message according to the detection result of the first message and the resource allocation result of the third message, then sends the scheduling results of the second message and the third message to the PHY layer, and simultaneously indicates that the higher layer HL performs the pre-configuration of the access resources for the UE access network according to the first message.

In the prior art, the pre-configuration of the access resource for the UE access network by the upper layer HL according to the first message is configured when the MAC layer receives the correct third message detection result and is a serial step, and in the invention, under the condition that the MAC layer successfully allocates the resources of the second message and the third message, the pre-configuration of the access resource for the UE access network by the upper layer HL according to the first message is used as a parallel step with the transmission of the resource allocation condition to the PHY layer, so that the access delay of the UE is reduced.

In the embodiment of the invention, firstly, under the condition that a physical PHY layer detects a first message sent by a terminal device UE, a Medium Access Control (MAC) layer performs resource allocation on a second message and a third message, then under the condition that the MAC layer performs successful resource allocation on the second message and the third message, the resource allocation condition is sent to the PHY layer, and meanwhile, a higher layer HL is indicated to perform pre-configuration of access resources for the UE to access a network according to the first message. Therefore, by advancing the configuration of HL on the access resource of the UE to the network and using the HL as the parallel flow of the second message and the third message processed by the MAC/PHY, the time consumption of the base station in a critical path can be reduced, the access time delay of the UE can be shortened, and the user service perception and the network index can be improved.

In the embodiment of the invention, the higher layer HL performs the pre-configuration of the access resource for the UE to access the network according to the first message, including at least one of the following: user index pre-allocation, physical channel resource pre-allocation and radio resource control setup message RRCSetup pre-generation.

Fig. 3 is a flow chart of an NR system resource allocation method according to another embodiment of the present invention, as shown in the following:

s301, in the case that the physical PHY layer detects the first message sent by the terminal device UE, the medium access control MAC layer allocates resources to the second message and the third message.

The specific implementation of S301 may refer to the content of S101 in the foregoing embodiment, which is not described herein.

S302, when the MAC layer successfully allocates the resources of the second message and the third message, the resource allocation situation is sent to the PHY layer, and meanwhile, the higher layer HL is instructed to pre-configure the access resources for the UE to access the network according to the first message.

The specific implementation of S302 may refer to the content of S102 in the foregoing embodiment, which is not described herein.

And S303, the PHY layer sends a second message to the UE based on the resource allocation condition and receives a third message fed back by the UE based on the second message.

In the embodiment of the present invention, as shown in fig. 2, the PHY layer generates a signal according to the MAC layer resource allocation result and the second message, sends the second message in the air interface slot of the second message, and sends a third message after the UE detects the second message, where the third message carries the signaling content of the rrcsetup request.

S304, the PHY layer detects the Physical Uplink Shared Channel (PUSCH) of the third message.

As shown in fig. 2, the PHY layer performs PUSCH detection of the third message in the air slot of the third message, and sends the detection result to the MAC.

S305, in case that the PUSCH detection result of the third message is correct, HL generates a radio resource control establishment request based on the third message, and simultaneously sends HL preconfigured access resources for the UE to access the network to the MAC layer.

As shown in fig. 2, the MAC receives the correct third message detection result, sends the decoding result to the HL, decodes the third message decoding result after the HL receives the third message decoding result, generates an rrcsetup request based on the decoding result, and sends the configured access resource to the MAC layer. In an embodiment of the invention, the decoding of the third message may be performed based on an abstract syntax notation (Abstract Syntax Notation One, ASN 1) approach.

In the embodiment of the invention, firstly, under the condition that a physical PHY layer detects a first message sent by a terminal device UE, a medium access control MAC layer performs resource allocation on a second message and a third message, then under the condition that the MAC layer successfully allocates the resources of the second message and the third message, the resource allocation condition is sent to the PHY layer, meanwhile, a higher layer HL is indicated to perform pre-configuration of access resources for the UE to access a network according to the first message, then the PHY layer sends the second message to the UE based on the resource allocation condition, and receives the third message fed back by the UE based on the second message, then the PHY performs PUSCH detection on the third message, finally, under the condition that the PUSCH detection result of the third message is correct, the HL generates a radio resource control establishment request RRCSetup request based on the third message, and meanwhile, the pre-configured access resources for the UE to access the network are sent to the MAC layer. By pre-configuring the access resource of the UE to the network in advance by HL and taking the pre-configured access resource as a parallel flow, the processing time delay of the base station can be reduced, and the normal access of the UE can not be influenced, so that the access efficiency of the UE is increased, and the goal of shortening the time delay of the control plane is finally achieved.

It should be noted that, as shown in fig. 2, after HL preconfigured access resources for accessing the network by the UE are sent to the MAC layer, the MAC layer is further required to allocate air interface resources to the fourth message based on the RRCSetup, send the resource allocation result of the fourth message to the PHY layer, and send the fourth message to the UE according to the resource allocation result through the PHY layer.

In the embodiment of the invention, when the physical uplink control channel (PUSCH) detection of the third message by the PHY layer fails, the PHY layer retransmits the third message until a retransmission stopping condition is met. It should be noted that, the retransmission condition includes that the number of times of retransmission of the third message reaches a preset number of times or the detection result of PUSCH detection of the third message by the PHY layer is correct. It should be noted that the preset number of times may be set in advance, and may be set according to actual design requirements, which is not limited in any way. And if the third message is retransmitted to the maximum times, deleting all information of the UE at the MAC side, waiting for the terminal to initiate the first message again, and releasing the preconfigured access resource for the UE to access the network through the HL.

It should be noted that, the set processing delays may be different for different processing nodes, where the processing delay at the base station side includes: the first message detection delay is typically within 1 slot (slot); the second message scheduling delay comprises processing time of the base station MAC and PHY, and is generally within 2-3 slots; the third message detection delay is generally within 1 slot; RRCSetup generates time delay, and physical resource allocation and Asn1 coding are required to be longer, and the time delay is generally more than 2ms due to the fact that UE (user equipment) is involved in user index allocation in a base station/cell; the fourth message scheduling delay, including processing time of the base station MAC and PHY, is typically within 2-3 slots.

Fig. 4 is a schematic overall flow chart of an embodiment of the present invention, firstly, a PHY layer detects in a PRACH configuration time slot, after detecting a first message, sends a detection result to an MAC layer, the MACK layer performs resource allocation of a second message and a third message, and simultaneously notifies HL to perform pre-allocation of access resources for a UE access network, if resource allocation fails, the flow is ended, if resource allocation of the second message and the third message is successful, the allocation result is sent to the PHY layer, the PHY layer sends the second message to the UE based on the resource allocation situation, and receives the third message fed back by the UE based on the second message, the PHY performs PUSCH detection on the third message, and when the PUSCH detection result of the third message is correct, HL generates a radio resource control establishment request based on the third message, and simultaneously sends HL pre-configured access resources for the UE access network to the MAC layer, the MAC layer performs air interface resource allocation to the fourth message based on the RRCSetup, and sends the resource allocation result of the fourth message to the PHY layer, and the PHY layer sends the fourth message to the UE according to the resource allocation result.
