Description

Technical Field

[0001] This invention relates to, but is not limited to, the field of wireless communication, and particularly to an information processing method, a base station, and a storage medium. Background Technology

[0002] In Stand Alone (SA) network architecture, a user equipment (UE) can transfer information from the source base station to the target base station through a non-contention-based handover process under certain conditions. Relevant standards specify the non-contention-based handover procedure under SA, such as... Figure 1 As shown, the UE sends the Reference Signal Receiving Power (RSRP) to the source base station, and the source base station returns a reconfiguration message to the UE. Subsequently, the UE and the target base station complete information processing through the interaction of the first message (Message 1, Msg1), the second message (Message 2, Msg2), and the third message (Message 3, Msg3).

[0003] However, before the target base station receives Msg3, it may receive downlink data. In this case, the target base station will send the downlink data to the UE. After receiving the downlink data, the UE needs to send uplink control information (UCI) back to the target base station in the uplink slot (U slot). Since Msg1 can be sent in any U slot, and Msg3 may also appear randomly in a U slot, Msg3 and UCI have a certain probability of appearing in the same U slot's Physical Uplink Control Channel (PUCCH), resulting in resource conflict. The relevant protocol stipulates that when resource conflict occurs, the UE will multiplex UCI and Msg3 onto the Physical Uplink Shared Channel (PUSCH) for transmission. The target base station can only determine whether multiplexing has occurred after receiving the information, causing a certain system delay. Summary of the Invention

[0004] The following is an overview of the subject matter described in detail herein. This overview is not intended to limit the scope of the claims.

[0009] The Msg3 is processed according to the feedback identifier of the UCI to complete the handover of the target UE base station.

[0010] In a second aspect, embodiments of the present invention provide a base station, comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the information processing method as described in the first aspect.

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0030] It should be noted that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, or the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0031] This invention provides an information processing method, a base station, and a storage medium. The information processing method includes: acquiring target demodulation information of a target air interface, wherein the target air interface is used to demodulate Msg3; when it is determined that the target demodulation information includes demodulation information of Msg3 and demodulation information of UCI of a target UE, generating a feedback identifier of UCI, determining based on the feedback identifier of UCI that the target UE has reused Msg3 and UCI in the PUSCH, and processing Msg3 based on the feedback identifier of UCI to complete the base station handover of the target UE. According to the solution provided by the embodiments of this invention, the target base station can determine the reuse scenario of information before receiving Msg3, reducing the latency of the target base station.

[0032] As will be understood by those skilled in the art, SA refers to a newly built 5G network, including base stations, backhaul links, and the core network. Handover under SA means that both the source and target base stations are 5G base stations. After receiving the A3 measurement report of the co-frequency neighboring cell from the UE, the base station triggers the handover process if the handover threshold is reached. During the handover process, the base station can configure the UE with either contention-based or non-contention-based handover. Non-contention-based handover allows the UE to access the target base station in a non-contention-based manner. In this case, both the target base station and the UE have received the reconfiguration message from the source base station, from which the UE can obtain the Random Access Channel (RACH) and Physical Random Access Channel (PRACH) configurations for non-contention-based access. Through non-contention-based handover, the UE can switch from one cell to another.

[0033] Those skilled in the art will understand that the relevant protocols specify a non-contention-based, random access procedure in SA handover scenarios. For example... Figure 1As shown, the UE sends a reference RSRP to the source base station, and the source base station returns a reconfiguration message to the UE. Subsequently, the UE initiates a random access request (Msg1, non-contention-based Preamble Index) to the target base station, and the target base station returns Msg2 (random access response information) to the UE. Then, the UE sends Msg3 (reconfiguration complete message) to the target base station. When the response to Msg3 is an acknowledgment (ACK), the handover process is completed.

[0034] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0035] like Figure 2 As shown, Figure 2 This is a flowchart of an information processing method provided in an embodiment of the present invention. The information processing method includes, but is not limited to, steps S210 and S220.

[0036] Step S210: Obtain the target demodulation information of the target air interface, wherein the target air interface is used to demodulate Msg3.

[0037] It is worth noting that after the target base station completes the transmission of information, the target demodulation information of the target air interface can be known in advance. Therefore, before receiving Msg3, it is possible to determine in advance whether there is information reuse due to resource duplication through the demodulation information of the target air interface.

[0038] It should be noted that the target air interface is the air interface used to demodulate Msg3 sent by the target UE. For different UEs, the target air interface can be different, and this embodiment does not impose any restrictions on this.

[0039] It is worth noting that since the target demodulation information of the target air interface changes with the transmission and reception of data, in order to ensure that the demodulation information obtained is for the multiplexing of Msg3 and UCI, the target base station can use the demodulation information obtained after Msg2 exits the air interface as the target demodulation information to ensure that the target demodulation information corresponds to Msg3.

[0040] Step S220: When it is determined that the target demodulation information includes the demodulation information of Msg3 and the demodulation information of UCI of the target UE, a feedback identifier of UCI is generated to determine that the target UE has reused Msg3 and UCI in PUSCH based on the feedback identifier of UCI.

[0041] It should be noted that since the U Slot sent by Msg1 is random, there is a certain probability of resource conflict between Msg3 and UCI. For example, if UCI takes Channel State Information (CSI) as an example, and the target base station's frame structure is 2.5 milliseconds double cycle (DDDSU DDSUU), and the CSI cycle is 40 milliseconds, then the probability of resource conflict between Msg3 and CSI is 1 / 12. As another example, if the target base station's frame structure is 5 milliseconds single cycle (DDDDD DDSUU), and the CSI cycle is 40 milliseconds, and the target UE needs to send a Hybrid Automatic Repeat Request-Acknowledgement (HARQ-ACK), then there is a probability of resource conflict between Msg3 and HARQ-ACK. Based on the above description, since resource conflicts are not inevitable but have a certain probability, it is possible to determine in advance whether a resource conflict will occur through the target demodulation information. When the target demodulation information includes both Msg3 demodulation information and UCI demodulation information, it can be determined that a resource conflict has occurred. The Msg3 received by the target air interface reuses UCI, thereby enabling the target base station to determine the reuse status of resources in advance, effectively improving the efficiency of information demodulation and reducing the latency of the base station.

[0042] It should be noted that the UCI feedback identifier can be generated for the target UE, enabling the target base station to pre-determine that the Msg3 multiplexed with UCI is in Msg3 before receiving it from the target UE. Those skilled in the art are motivated to adjust the specific form of the UCI feedback identifier according to actual needs, and this embodiment will not impose any limitations here.

[0043] Step S230: Process Msg3 according to the feedback identifier of UCI to complete the target UE base station handover.

[0044] It should be noted that, based on the feedback identifier of UCI, the reuse scenario of Msg3 and UCI can be determined in advance. This reduces the identification time of the target base station during operations such as demodulation and retransmission scheduling of Msg3, thereby reducing system latency. Specifically, in the demodulation of Msg3, when the target base station has the feedback identifier of UCI, it can determine that Msg3 and UCI are reused in the PUSCH before receiving Msg3, thus reducing the identification time for the target base station. When retransmission scheduling of Msg3 is required, the feedback identifier of UCI enables the target base station to determine whether the Redundancy Version (RV) should be flipped, thus determining in advance whether to perform operations such as merging and decoding, thereby saving processing time for the target base station.

[0045] In another embodiment of the present invention, the demodulation information of UCI includes at least one of the following:

[0046] Demodulation information from HARQ-ACK;

[0047] CSI demodulation information.

[0048] It is worth noting that HARQ-ACK and CSI in UCI can be transmitted on both PUCCH and PUSCH, while Scheduling Request (SR) can only be sent on PUCCH. When HARQ-ACK and / or CSI are transmitted on the same uplink U Slot as PUSCH, UCI will be multiplexed and transmitted on PUSCH. Since UCI includes various types of information, the specific information type in UCI can be further determined and marked with the corresponding feedback identifier, further improving the demodulation efficiency of the base station.

[0049] It is understood that the HARQ-ACK and CSI information types described in this embodiment are only two available embodiments. If the UCI includes other information types that may be reused with Msg3, corresponding feedback identifiers can also be added. This embodiment does not impose any limitations on this.

[0050] Additionally, in one embodiment, the UCI feedback identifier includes the HARQ-ACK feedback identifier and / or the CSI feedback identifier, as referred to Figure 3 , Figure 2 Step S220 in the illustrated embodiment also includes, but is not limited to, the following steps:

[0051] Step S310: When the demodulation information of UCI includes the demodulation information of HARQ-ACK, generate the HARQ-ACK feedback flag.

[0052] or,

[0053] Step S320: When the demodulation information of UCI includes the demodulation information of CSI, generate a feedback identifier for CSI.

[0054] or,

[0055] Step S330: When the demodulation information of UCI includes the demodulation information of HARQ-ACK and the demodulation information of CSI, the feedback identifiers of HARQ-ACK and CSI are generated respectively.

[0056] It should be noted that after the target UE receives downlink data, it may respond with HARQ-ACK, CSI, or both. Therefore, the specific UCI type can be determined from the target demodulation information. Based on the information type corresponding to the specific demodulation information, different identifiers can be generated, so that the base station can more accurately know the type of information to be demodulated and reduce system latency.

[0057] It is understood that the number of generated feedback identifiers can be arbitrary, and can be adjusted according to the number of information types determined in the demodulation information of UCI. For example, if HARQ-ACK is determined in step S310 and CSI is determined in step S320, then feedback identifiers for HARQ-ACK and CSI are generated respectively. Or, if UCI includes both HARQ-ACK and CSI in step S330, then feedback identifiers for HARQ-ACK and CSI can be generated simultaneously. This embodiment does not impose any limitation on the number of feedback identifiers.

[0058] Additionally, in one embodiment, reference is made to Figure 4 In execution Figure 2 Before the UCI feedback identifier generation operation in step S220 of the illustrated embodiment, the following steps are included, but are not limited to:

[0059] Step S410: Determine the UE to which the demodulation information of UCI belongs;

[0060] Step S420: When it is determined that the UE to which the demodulation information of the UCI belongs is the target UE, the step of generating the feedback identifier of the UCI is executed.

[0061] It is worth noting that the target base station can establish connections with any number of UEs, and the demodulation information of UCI in the target air interface may belong to any UE. Therefore, before generating the feedback identifier of UCI, it can be determined that the demodulation information of UCI belongs to the target UE to ensure the accuracy of the data.

[0062] Additionally, in one embodiment, reference is made to Figure 5 In execution Figure 2 Following step S220 in the illustrated embodiment, the following steps may also be included, but are not limited to:

[0063] Step S510: Demodulate Msg3 multiplexed in PUSCH according to the feedback flag of UCI;

[0064] Step S520: Obtain the CRC feedback corresponding to Msg3;

[0065] In step S530, when the CRC feedback is ACK, it is determined that the target UE has completed the base station handover; or, when the CRC feedback is non-deterministic (Negative Acknowledgment, NACK), Msg3 retransmission scheduling is performed to complete the base station handover based on the Msg3 retransmitted by the target UE.

[0066] It should be noted that when the CRC feedback for Msg3 is ACK, it indicates that the target base station has completed the reception and demodulation of Msg3, the base station handover for the target UE is complete, and the handover process can end. When the CRC feedback for Msg3 is NACK, Msg3 retransmission scheduling is required, causing the target UE to retransmit Msg3. In this case, the target UE will retransmit Msg3, which may again cause resource conflicts with UCI. Therefore, the steps of obtaining target demodulation information and generating the feedback identifier of UCI can be re-executed to ensure that the target base station can pre-identify whether the retransmitted Msg3 contains a reused UCI. Understandably, the steps of re-executing the steps of obtaining target demodulation information and generating the feedback identifier of UCI can be referenced... Figure 2 The description of the embodiments shown is omitted here for the sake of simplicity.

[0067] Additionally, in one embodiment, reference is made to Figure 6 , Figure 5 Step S520 in the illustrated embodiment also includes, but is not limited to, the following steps:

[0068] Step S610: While keeping RV unchanged, discard the transport block (TB) corresponding to the current CRC feedback;

[0069] Step S620: Send Downlink Control Information (DCI) to the target UE to enable the target UE to retransmit Msg3.

[0070] Those skilled in the art will understand that in common retransmission processes, the RV version field is valued in the normal reverse order, and TB merging and decoding are performed because the received information may contain correct information. However, in the technical solution of this embodiment, due to the presence of the UCI feedback flag and the probability of resource conflicts between Msg3 and UCI, when the CRC result is NACK, the transmission is considered an erroneous transmission. Each TB in the CRC does not have merging value. If information is reused, it may lead to the reuse of the UCI feedback flag, causing demodulation errors during retransmission. Therefore, the retransmission process used by Msg3 can be determined by detecting the presence of the UCI feedback flag. The following, combined with... Figure 7 and Figure 8Examples are given for two scenarios: one where there is no UCI feedback identifier and the other where there is a UCI feedback identifier.

[0071] Reference Figure 7 If the CRC result of Msg3 is NACK and there is no feedback identifier for the UCI corresponding to the target air interface and the target UE, then the version field of RV is taken in the normal flip order, and Msg3 is retransmitted by sending DCI to the target UE.

[0072] Reference Figure 8 If the CRC result of Msg3 is NACK and there is a feedback flag for the UCI corresponding to the target air interface and the target UE, when scheduling the retransmission of Msg3, the RV version remains unchanged, that is, the value is not taken in the normal RV version flip order, and the current TB is discarded. Then, the DCI of Msg3 is sent to the target UE, so that the target UE can retransmit Msg3.

[0073] Additionally, in one embodiment, reference is made to Figure 9 In execution Figure 2 Before step S210 in the illustrated embodiment, the method further includes:

[0074] Step S910: The air interface used to receive Msg1 sent by the target UE is determined as the target air interface.

[0075] It should be noted that for random access procedures without contention, the target base station usually processes Msg1, Msg2 and Msg3 through the same air interface. Therefore, the air interface used to receive Msg1 can be identified as the target air interface to ensure that the acquired target demodulation information belongs to the correct air interface.

[0076] Additionally, in one embodiment, reference is made to Figure 10 In execution Figure 2 Before step S210 in the illustrated embodiment, the method further includes:

[0077] Step S1010: Determine the first air interface time, which is the time when Msg1 is received;

[0078] Step S1020: Determine the second air interface time and the third air interface time based on the first air interface time, wherein the second air interface time is the time to send Msg2 and the third air interface time is the time to receive Msg3.

[0079] Step S1030: Between the second air interface time and the third air interface time, perform the operation of acquiring the target demodulation information of the target air interface.

[0080] It should be noted that the first air interface time is the time when the target air interface receives Msg1. Since the process from Msg1 to Msg3 is determinable, the second and third air interface times can be determined based on the first air interface time. The specific calculation method is not an improvement of this implementation and will not be elaborated here.

[0081] It should be noted that after the target base station initiates a Msg2 scheduling request to the target UE and Msg2 exits the air interface, user plane data access is enabled. At this time, downlink data will arrive at the target base station, which will then send the downlink data to the target UE, thus generating UCI feedback. Since the demodulation information of the target air interface can change, to ensure that the demodulation information reflects the multiplexing status of Msg3 and UCI, the demodulation information acquired at any time between the second and third air interface times can be determined as the target demodulation information to determine whether there is UCI demodulation of the target UE. For example, the target demodulation information can be acquired after the target base station receives the Msg3 scheduling request packet. The specific time point is selected according to actual needs, ensuring it is between the second and third air interface times.

[0082] The following combination Figure 11 and Figure 12 The random access process of this embodiment will be illustrated through two specific examples.

[0083] Reference Figure 11 The target UE randomly sends Msg1 to the target base station. The target base station calculates the second and third air interface times based on the first air interface time received from Msg1. The target base station initiates a scheduling request for Msg2. After Msg2 exits the air interface, the target base station receives downlink data and sends the downlink data to the target UE. After the target base station receives the Msg3 scheduling request packet, it obtains the target demodulation information of the target air interface and determines that there is demodulation information with CSI, and generates a CSI feedback flag. When the target base station receives Msg3, it performs demodulation according to the scenario of multiplexing Msg3 and CSI due to the presence of the CSI feedback flag.

[0084] Reference Figure 12The target UE randomly sends Msg1 to the target base station. The target base station calculates the second and third air interface times based on the first air interface time received from Msg1. The target base station initiates a scheduling request for Msg2. After Msg2 exits the air interface, the target base station receives downlink data and sends the downlink data to the target UE. After the target base station receives the scheduling request packet for Msg3, it obtains the target demodulation information of the target air interface and determines that there is demodulation information with HARQ-ACK, generating a feedback flag for HARQ-ACK. When the target base station receives Msg3, demodulation is performed according to the scenario of multiplexing Msg3 and HARQ-ACK due to the presence of the feedback flag for HARQ-ACK.

[0085] Additionally, refer to Figure 13 This invention also provides an information processing method applied to a target-side base station, including but not limited to the following steps:

[0086] Step S1310: The target base station is configured as SA type, handover mode, non-contention access, and the frame structure and resource period are determined. If there is UCI feedback in the U slot of the target UE sending Msg3, step S1321 is executed; otherwise, step S1322 is executed.

[0087] Step S1321: Determine the UCI feedback identifier. If the UCI demodulation information includes the CSI demodulation information, proceed to step S1331. If the UCI demodulation information includes the HARQ-ACK demodulation information, proceed to step S1332. If the UCI demodulation information includes both the CSI demodulation information and the HARQ-ACK demodulation information, proceed to step S1333.

[0088] Step S1322: Determine that Msg3 and UCI will not be reused, and perform subsequent operations using the existing process;

[0089] Step S1331: Generate a feedback identifier for CSI, and proceed to step S1340;

[0090] Step S1332: Generate a feedback flag for HARQ-ACK and proceed to step S1340.

[0091] Step S1333: Generate the feedback flag for CSI and the feedback flag for HARQ-ACK, and then proceed to step S1340.

[0092] Step S1340: Determine whether Msg3's CRC is ACK. If yes, the base station handover is complete and the process ends. If no, proceed to step S1350.

[0093] Step S1350: Perform Msg3 retransmission scheduling, keeping the RV version unchanged.
