Description

Method for solving out-of-order scheduling between different priority services in NR system
Technical Field
The invention belongs to the technical field of mobile communication, and particularly relates to a method for solving unordered scheduling among services with different priorities in an NR (noise-and-noise) system.
Background
The ITU defines three general application scenarios for 5G: the intelligent terminal user online peak rate is 10Gbps or even 20Gbps in the scene; secondly, the large-connection internet of things mMTC (massive Machine Type communication) requires that the number of the connections of people and objects supported by the 5G network reaches 100 ten thousand per square kilometer; thirdly, high reliability Low Latency communication urllc (ultra Reliable and Low Latency communication), which means that the Latency of 5G network reaches 1 millisecond. Currently, NR gradually permeates to large connections and low latency classes from a large bandwidth scene, and in order to meet the requirements of next-generation NR networks, 3GPP has performed a series of standardization work for services such as eMBB and URLLC.
In the NR eMBB system, for uplink transmission scheduled by a UL grant, the UE does not expect that new uplink scheduling information needs to be received and data transmission is performed after the UE receives the UL grant and before the UE transmits a corresponding PUSCH.
However, since multiple network services in NR may exist simultaneously, in some cases URLLC services with higher priority may occur after eMBB services (i.e., out-of-order scheduling occurs), and according to the above analysis, URLLC data must be transmitted after eMBB data.
Since the URLLC data must be transmitted after the eMBB data, and the URLLC service has a high requirement on delay, when the duration of the eMBB data is up to 1ms, the URLLC packet has a large delay, which is very disadvantageous for the URLLC service with high requirement on delay.
Based on the above technical problems in the prior art, the present inventors propose a method for solving out-of-order scheduling between different priority services in an NR system, in combination with many years of research experience.
Disclosure of Invention

In order to achieve the purpose, the invention adopts the following technical scheme:
a method of resolving out-of-order scheduling between different priority traffic in an NR system comprising:
step 1: the base station side checks whether the scheduled eMBB HARQ (the HARQ feedback of eMBB data) is received or not, the base station side enters the step 3 after receiving the scheduled eMBB HARQ, and the base station side enters the step 2 without receiving the scheduled eMBB HARQ;
step 2: the base station side scrambles the URLLC scheduling information by using an auxiliary (cell radio network temporary identifier) C-RNTI, then scrambles the URLLC scheduling information scrambled by using the main C-RNTI and enters a step 4;
and step 3: the base station side scrambles URLLC scheduling information by using the main C-RNTI and then performs step 4;
and 4, step 4: the UE (user equipment) side detects the scheduling information sent from the base station side;

and step 9: the UE side knows that the base station configures another eMBB HARQ transmission resource for the UE side after URLLC HARQ transmission resource, and then enters step 10;
step 10: the UE side acquires time-frequency resource information which is distributed by the base station side for the UE side and used for sending URLLC HARQ;
step 11: and the UE side sends the HARQ feedback on the corresponding resources allocated by the base station side.
Furthermore, the base station side enables the UE side to detect whether the current scheduling information is sent to the UE side by the base station side in a blind detection mode through the primary C-RNTI scrambling scheduling information and/or the auxiliary C-RNTI scrambling scheduling information.
Further, the base station side distributes two identity identification information for the auxiliary C-RNTI and the main C-RNTI, the two identity identification information have different values, when scrambling is carried out only by the main C-RNTI, the situation that unordered scheduling does not occur is shown, and scrambling is carried out by the auxiliary C-RNTI and the main C-RNTI, the situation that unordered scheduling occurs is shown.
Further, in step 5, the UE side can determine whether the current scheduling information is the scheduling of the base station side for itself through descrambling, and if the descrambling is correct, the UE side determines that the base station side schedules itself, and if the descrambling is incorrect, the UE side determines that the base station side does not schedule itself.
Further, in step 2, the auxiliary C-RNTI is represented by 16-bit binary bits, and when scrambling is performed by adopting the auxiliary C-RNTI, modulo-2 addition is performed on the 16-bit binary bits corresponding to the auxiliary C-RNTI and the CRC added to the data stream part, so as to complete the scrambling operation.
Further, in step 3, the main C-RNTI is represented by 16-bit binary bits, and when scrambling is performed by using the main C-RNTI, modulo-2 addition is performed on the 16-bit binary bits corresponding to the main C-RNTI and the CRC added to the data stream part, so as to complete the scrambling operation.
Further, in step 9, the UE side has the capability of sequentially processing two scheduling information with different priorities through the configured eMBB PUSCH transmission resources.
Compared with the prior art, the invention has the following advantages:

step 1: the base station side checks whether the scheduled eMBB HARQ is received or not, the base station side enters the step 3 after receiving the scheduled eMBB HARQ, and the base station side enters the step 2 without receiving the scheduled eMBB HARQ;

step 10: the UE side acquires time-frequency resource information of URLLC HARQ distributed by the base station side for the UE side;
step 11: and the UE side sends the HARQ feedback on the corresponding resources allocated by the base station side.
In the embodiment, the base station side enables the UE side to detect whether the current scheduling information is sent to the UE side by the base station side in a blind detection mode through the primary C-RNTI scrambling scheduling information and/or the auxiliary C-RNTI scrambling scheduling information.
In this embodiment, the auxiliary C-RNTI and the main C-RNTI are two pieces of identity identification information allocated to the base station, the values of the auxiliary C-RNTI and the main C-RNTI are different and are both represented by 16 bits, when scrambling is performed only by the main C-RNTI, the situation that the disordered scheduling does not occur is represented, and when scrambling is performed by the auxiliary C-RNTI and the main C-RNTI, the disordered scheduling occurs is represented, which is equivalent to an implicit indication whether the disordered scheduling exists for a user.
In step 5 of this embodiment, the UE side can determine whether the current scheduling information is the scheduling of the base station side for itself through descrambling, and if the descrambling is correct, the UE side determines that the base station side schedules itself, and if the descrambling is incorrect, the UE side determines that the base station side does not schedule itself.
In this embodiment, the base station side determines whether to use two-step scrambling or one-step scrambling for the URLLC DCI scheduled out of order according to whether the scheduled eMBB HARQ feedback has been received, where the purpose of the scrambling is to ensure that the UE side can know that the base station side dynamically configures another eMBB HARQ transmission resource for the UE side.
In this embodiment, when detecting scheduling information, the UE side determines whether to perform descrambling of the secondary C-RNTI according to the descrambling condition using the primary C-RNTI, where an implicit condition of attempting descrambling of the secondary C-RNTI is that the UE does not process and feeds back the eMBB HARQ in time, and expects to obtain extra processing time and transmission resources to transmit the eMBB HARQ that has not been sent in time.
In step 2 of this embodiment, the auxiliary C-RNTI is represented by 16-bit binary bits, and when scrambling is performed by using the auxiliary C-RNTI, modulo-2 addition is performed on the 16-bit binary bits corresponding to the auxiliary C-RNTI and the CRC added to the data stream portion, thereby completing the scrambling operation.
In step 3 of this embodiment, the main C-RNTI is represented by 16-bit binary bits, and when scrambling is performed by using the main C-RNTI, modulo-2 addition is performed on the 16-bit binary bits corresponding to the main C-RNTI and the CRC added to the data stream portion, thereby completing the scrambling operation.
In step 5 of this embodiment, the main C-RNTI is represented by 16-bit binary bits, and when the main C-RNTI is used for descrambling, modulo-2 addition is performed on the 16-bit binary bits corresponding to the main C-RNTI and the CRC added to the data stream part to complete the descrambling operation, and CRC check is performed in subsequent steps.
In step 6 of this embodiment, the auxiliary C-RNTI is represented by 16-bit binary bits, and when the auxiliary C-RNTI is used for descrambling, modulo-2 addition is performed on the 16-bit binary bits corresponding to the auxiliary C-RNTI and the CRC added to the data stream part to complete the descrambling operation, and CRC check is performed in subsequent steps.
The service unordered scheduling method is realized by scrambling scheduling information by using a group of main C-RNTI and auxiliary C-RNTI which are allocated by a high layer, wherein the auxiliary C-RNTI implicitly indicates a plurality of frequency domain resources which are different in the same time domain, the information such as the positions and the numbers of the plurality of corresponding frequency domain resources is informed to UE by a base station by using RRC signaling in advance, the time domain is defaulted to be the time domain resource (fixed time offset) after URLLC service transmission is finished and the time interval is the same as the eMBB initial scheduling time interval, and for the base station side, the UE side can be implicitly informed by adopting the main C-RNTI and the auxiliary C-RNTI to carry out two-step scrambling on the scheduling information: the base station side allocates additional time-frequency resources for eMBB data transmission or feedback for the eMBB data transmission or feedback, so that the UE side has the capability of sequentially processing two different priority scheduling information and preparing data transmission or feedback for the eMBB data.
For uplink transmission of UL grant scheduling, a base station side determines whether two-step scrambling (main C-RNTI and auxiliary C-RNTI) or one-step scrambling (main C-RNTI) is adopted for the disordered scheduled URLLC UL grant according to whether eBB PUSCH data is received or not during sending, namely the base station side judges the scrambling mode of the URLLC UL grant according to whether the eBB PUSCH data is received or not before scheduling the URLLC PUSCH data transmission, if the eBB PUSCH is received, the traditional method is adopted, namely the URLLC UL grant scheduling information is scrambled by only using the main C-RNTI, if the URLLC UL grant scheduling information is not received, the URLLC UL grant scheduling information scrambled by using the auxiliary C-RNTI is scrambled again by using the main C-RNTI, and the purpose is to ensure that the UE side can know that another eBB transmission resource is dynamically configured for the UE side by the PUSCH side, the base station side can detect eMBMS PUSCH from the UE side on a plurality of possible eMBMS PUSCH transmission resources indicated by the auxiliary C-RNTI during receiving, wherein the plurality of possible transmission resources comprise eMBMS PUSCH time-frequency resources scheduled firstly and a plurality of eMBMS PUSCH time-frequency resources implicitly indicated by the auxiliary C-RNTI; when receiving, the UE side judges whether to carry out secondary C-RNTI descrambling according to the descrambling condition of using the main C-RNTI, wherein the implicit condition of trying the secondary C-RNTI descrambling is that the UE side does not process and transmit eMBB data in time and expects to obtain extra processing time and transmission resources to transmit eMBB services which are not transmitted in time, the UE side uses the main C-RNTI to descramble when receiving URLLC UL grant scheduling information, if CRC check is successful, information such as URLLC PUSCH time-frequency resources and the like distributed by the base station for the UE can be obtained, if CRC check is failed, descrambling is tried to be carried out again by using the secondary C-RNTI, if CRC check is successful, the UE not only can obtain information such as URLLC PUSCH time-frequency resources and the like distributed by the base station for the UE, but also can obtain that the base station dynamically configures another eMBPUSCH transmission resource for the UE, and if CRC check is failed, the base station reschedules the URLLC data again, and after the UE side sends the URLLC service, selecting to transmit eMBB PUSCH on the allocated available time-frequency resources according to the processing capacity and the channel condition of the UE side.

In fig. 2(b), the base station side first transmits the PDSCH scheduled by the eMBB DCI, and since the URLLC service arrives at the base station side at this time, the eMBB DCI scheduling information is scrambled by using the auxiliary C-RNTI first and then the eMBB DCI scheduling information scrambled by using the auxiliary C-RNTI is scrambled again by using the main C-RNTI when the HARQ feedback corresponding to the eMBB PDSCH is not received; the method comprises the steps that a user side receives eBB DCI and a corresponding PDSCH and then prepares HARQ feedback corresponding to the eBB PDSCH, new scheduling information is detected when the user side prepares the HARQ feedback corresponding to the eBB PDSCH, processing of the eBB PDSCH and the HARQ feedback corresponding to the eBB PDSCH is stopped at the moment, the eBB HARQ feedback which is not processed is obtained at the moment, the eBB HARQ feedback is firstly descrambled by using a main C-RNTI, then the eBB HARQ feedback is descrambled by using an auxiliary C-RNTI, CRC verification is successful, the UE knows that the base station allocates HARQ feedback time-frequency resources and other information corresponding to URLLC services of the UE, and can also know that the base station dynamically configures another eBB HARQ feedback transmission resource for the UE.
As shown in fig. 3, in the figure, the abscissa represents time resources, and the ordinate represents frequency domain resources, where fig. 3(a) is a schematic diagram of collision between eMBB downlink transmission feedback scheduled by DCI and URLLC uplink transmission scheduled by UL grant; fig. 3(b) is a schematic diagram of solving a conflict between eMBB downlink transmission feedback scheduled by DCI and URLLC uplink transmission scheduled by UL grant, as shown in fig. 3(a), a protocol does not expect that a high-priority (e.g., URLLC) service needs to be transmitted within an eMBB data scheduling time, but in order to support applications in multiple 5G scenarios, if the URLLC service is processed after eMBB data is processed, a large transmission delay is generated for the URLLC service, and therefore data transmission in multiple scenarios needs to be further standardized; in fig. 3(b), the base station side first transmits the PDSCH scheduled by the eMBB DCI, and since the URLLC service arrives at the base station side at this time, the eMBB DCI scheduling information is scrambled by using the auxiliary C-RNTI first and then the eMBB DCI scheduling information scrambled by using the auxiliary C-RNTI is scrambled again by using the main C-RNTI when the HARQ feedback corresponding to the eMBB PDSCH is not received; the method comprises the steps that a user side receives eBB DCI and a corresponding PDSCH and then prepares HARQ feedback corresponding to the eBB PDSCH, new scheduling information is detected when the user side prepares the HARQ feedback corresponding to the eBB PDSCH, processing of the eBB PDSCH and the HARQ feedback corresponding to the eBB PDSCH is stopped at the moment, the eBB HARQ feedback which is not processed is obtained at the moment, the eBB HARQ feedback is firstly descrambled by using a main C-RNTI, then the eBB HARQ feedback is descrambled by using an auxiliary C-RNTI, CRC verification is successful, the UE knows that the base station allocates HARQ feedback time-frequency resources and other information corresponding to URLLC services of the UE, and can also know that the base station dynamically configures another eBB HARQ feedback transmission resource for the UE. Since PUSCH scheduled by UL grant (horizontal line shading) is transmitted after eMBB data is fed back, URLLC data transmission delay is caused. Because the eMMC has relatively low time delay requirement, the low time delay requirement of the URLLC service is ensured, and the retransmission times of eMMC data are reduced to a certain extent.
