Description

Information processing method and device

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on August 11, 2023, with application number 202311013662.8 and application name “Information Processing Method and Device,” the entire contents of which are incorporated by reference into this disclosure. Technical Field

[0002] The present disclosure relates to the field of communication technology, and in particular to an information processing method and device. Background Art

[0003] In the related art, the solutions for Layer 1 (L1) or Layer 2 (L2) mobility include intra-DU cell switching and inter-DU cell switching scenarios.

However, before the terminal performs cell switching, it does not know whether the candidate cell is the target cell to be accessed by the terminal, making it difficult to perform the corresponding operation in advance.

[0226] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0227] The terms "first," "second," and the like in the specification and claims of the present disclosure are used to distinguish similar objects and are not necessarily used to describe a particular order or sequential sequence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments of the present disclosure described herein may be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having," and any variations thereof, are intended to cover non-exclusive inclusions, e.g., a process, method, system, product, or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products, or apparatus.

[0228] In the embodiments of the present disclosure, the term "and / or" describes the relationship between associated objects, indicating that three possible relationships exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship. In the embodiments of the present disclosure, the term "plurality" refers to two or more, and other quantifiers are similar.

[0229] In the embodiments of the present disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present disclosure should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0230] Figure 1 shows a block diagram of a wireless communication system applicable to embodiments of the present disclosure. The wireless communication system includes a terminal device 11 and a network-side device (or network device) 12. The terminal device 11 may also be referred to as a terminal or user equipment (UE). It should be noted that the specific type of the terminal 11 is not limited in the embodiments of the present disclosure. The network-side device 12 may be a base station or a core network. It should be noted that the embodiments of the present disclosure only take a base station in a New Radio (NR) system as an example, but the specific type of the base station is not limited.

[0231] In order to enable those skilled in the art to better understand the embodiments of the present disclosure, the following description is first given.

[0232] In related technologies, cell switching can only be triggered by the network side based on Layer 3 (L3) measurements, and cell switching includes real-time switching and conditional switching.

[0233] (1) Real-time switching:

[0234] When the centralized unit (CU) decides to switch the UE from the current serving cell to another cell, the source node (source node) and the target node (target node) first coordinate the switching resources through a switching request process. After the coordination is completed, a radio resource control (RRC) reconfiguration message is sent to the UE, which carries the configuration information required for the UE to access the target cell. When the UE receives the RRC reconfiguration message sent by the network side, the UE applies the configuration information of the target cell included in the reconfiguration message, initiates random access to the target cell side for synchronization, and feeds back an RRC reconfiguration completion message to the target cell side to indicate that the UE has successfully accessed the target cell of the target distributed unit (DU).

[0235] (2) Conditional switching:

[0236] The CU pre-configures multiple candidate cells for the UE, that is, the configuration information and execution conditions of the candidate cells are sent to the UE in advance. When the UE receives the configuration information of the candidate cells, it will not immediately perform switching or PSCell change or PSCell addition like traditional switching, primary secondary cell (PSCell) change or PSCell addition. Instead, it will save the received configuration and perform measurement and evaluation on the configured candidate cells until a cell that meets the execution conditions is found. The UE will then execute the stored reconfiguration message corresponding to the cell and perform the corresponding switching or PSCell change or PSCell addition process, that is, complete downlink synchronization and trigger the random access process to access the target primary serving cell (PCell) or PSCell. After the UE successfully accesses, it will feedback the reconfiguration completion message to the network.

[0237] In the related technology, a cell change mechanism based on L1 / L2 commands will be supported. The cell change mechanism based on L1 / L2 commands implements a faster process than that based on L3 commands. At the same time, the cell change mechanism based on L1 / L2 commands is not limited to handover and PSCell changes, but can also be applied to secondary cells (SCells). To support mobility based on L1 / L2 commands, the CU needs to request the configuration information of the candidate cell from the candidate DU in advance and pre-configure this information to the UE in advance through RRC messages. The UE performs L1 measurements on the neighboring cells based on the received configuration and reports it to the serving DU. The serving DU makes a handover decision based on the measurement report.

[0238] The information processing method provided by the embodiments of the present disclosure is described in detail below through some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0239] As shown in FIG2 , an embodiment of the present disclosure provides an information processing method, which is executed by a first network device. The method includes:

[0240] Step 201: Sending instruction information to the second network device;

[0241] The indication information includes information required by the second network device to perform terminal access management and / or resource management.

[0242] Optionally, before the terminal changes or adds a serving cell, indication information is sent to the second network device.

[0243] In the embodiment of the present disclosure, the first network device is a source base station, and the second network device is a candidate base station;

[0244] Alternatively, the first network device is a source distributed unit DU, and the second network device is a target distributed unit DU.

[0245] Optionally, the serving cell change or addition includes at least one of the following:

[0246] The primary serving cell (PCell) is changed. The PCell can also be the primary serving cell of the primary cell group (in dual connectivity scenarios);

[0247] Cell switching;

[0248] Primary SCG Cell (PSCell) change;

[0249] PSCell added.

[0250] Before the terminal changes or adds a serving cell, the first network device receives an L1 measurement result from the terminal, performs an evaluation based on the L1 measurement result, and after obtaining certain candidate cells (candidate cells) to which the terminal may switch based on the evaluation, sends the above-mentioned indication information to the second network device to facilitate the second network device to perform terminal access management operations and / or resource management operations. That is, the above-mentioned indication information is sent after measuring the candidate cells and before changing or adding the serving cell.

[0251] For example, when a candidate cell is a candidate cell to which the terminal may switch, the indication information is used to instruct the second network device corresponding to the candidate cell to perform terminal access management operations to reduce access delay. For another example, when a candidate cell is a candidate cell to which the terminal cannot switch, the indication information is used to instruct the second network device corresponding to the candidate cell to perform resource management operations, which can be uplink resource release or resource deactivation operations to avoid resource waste.

[0252] Optionally, the terminal access management operation includes an uplink resource scheduling operation and / or a beam angle adjustment operation.

[0253] In the embodiment of the present disclosure, the first network device may determine whether to change or add a serving cell based on the L1 measurement result reported by the terminal, or a threshold may be preconfigured for the terminal, and the terminal performs L1 measurement and reports, and determines whether to change or add a serving cell.

[0254] Optionally, the indication information includes at least one of the following:

[0255] a first probability, where the first probability information is used to indicate a probability predicted by the first network device that the serving cell is changed to at least one candidate cell, or a probability predicted by the first network device that the beam of the serving cell is changed to a candidate beam of at least one candidate cell;

[0256] a second probability, where the second probability information is used to indicate a probability predicted by the first network device that at least one candidate cell is added as a serving cell, or a probability predicted by the first network device that a candidate beam of at least one candidate cell is added as a beam of the serving cell;

[0257] First object indication information, where the first object indication information is used to indicate at least one first object predicted by the first network device, the first object including at least one candidate cell or a candidate beam of at least one candidate cell; wherein the first probability corresponding to the first object satisfies a first switching condition, or the second probability corresponding to the first object satisfies a second switching condition;

[0258] Second object indication information, the second object indication information is used to indicate at least one second object, the second object includes at least one candidate cell or a candidate beam of at least one candidate cell; wherein, the first probability corresponding to the second object does not meet the first switching condition, or the second probability corresponding to the second object does not meet the second switching condition.

[0259] Optionally, the first switching condition includes a first probability being greater than or equal to a first preset threshold, and the second switching condition includes a second probability being greater than or equal to a second preset threshold.

[0260] In the embodiment of the present disclosure, the first probability and the second probability may be specifically integers. For example, a larger value of the first probability indicates a higher probability. For example, the first probability and the second probability may be expressed as INTEGER(1, ..., 100) respectively.

[0261] In the embodiment of the present disclosure, only the first probability or first object indication information may be carried to instruct the second network device to schedule uplink resources for terminal access, adjust the beam angle, etc., to wait for the terminal to access. Alternatively, only the second probability or second object indication information may be carried to indicate that the candidate cell corresponding to the second network device may not be accessed, and no uplink resources need to be reserved, or uplink resources may be temporarily deactivated. Alternatively, both the first probability or first object indication information and the second probability or second object indication information may be carried, that is, candidate cells or candidate beams with high and low switching probabilities are simultaneously indicated.

[0262] As an example, when the above-mentioned indication information includes the above-mentioned first object indication information, the indication information is specifically a high probability indication, which is used to indicate that the probability predicted by the first network device to change the service cell or beam to at least one first object is greater than or equal to a first preset threshold, or to indicate that the probability predicted by the first network device to add at least one first object as a service cell or beam is greater than or equal to a second preset threshold.

[0263] As an example, when the above-mentioned indication information includes the above-mentioned second object indication information, the indication information is specifically a low probability indication, which is used to indicate that the probability predicted by the first network device to change the service cell or beam to at least one second object is less than a first preset threshold, or to indicate that the probability predicted by the first network device to add at least one second object as a service cell or beam is less than a second preset threshold.

[0264] Optionally, the instruction information further includes at least one of the following:

[0265] Transmission Configuration Indicator (TCI) status information of at least one candidate cell, where the TCI status information corresponds to a candidate beam and the corresponding candidate beam can be determined based on the TCI status information;

[0266] The probability information of the terminal activating the TCI state, which can be understood as the probability of the terminal switching to the candidate beam corresponding to the TCI state;

[0267] Terminal identification;

[0268] Serving cell identifier;

[0269] identification of one or more candidate cells;

[0270] Layer 1 measurement result information, through which the second network device can determine at least one of the first probability, the second probability, the first object indication information, and the second object indication information.

[0271] As an example, the above indication information may include a list, as shown in Table 1, including identifiers of multiple candidate cells and corresponding handover probabilities.

[0272] Table 1

[0273] The information element (IE) structure corresponding to Table 1 above is shown in Table 2:

[0274] Table 2

[0275] in, <max>Indicates the maximum number of candidate cells in a candidate DU.

[0276] In addition to carrying the candidate cell identifier, it can also carry the corresponding TCI status information, as shown in Table 3.

[0277] Table 3

[0278] The IE structure corresponding to Table 3 above is shown in Table 4:

[0279] Table 4

[0280] The above example describes a case where the indication information carries multiple candidate cells. In the embodiments of the present disclosure, the indication information may also carry only one candidate cell. That is, the indication information includes a candidate cell identifier and a handover probability corresponding to the candidate cell identifier, such as the IE structure shown in Table 2. In this case, the potential conditional handover cell list carries one candidate cell. The indication information may also include TCI state information corresponding to the candidate cell, such as the IE structure shown in Table 4. In this case, the potential conditional handover cell list carries one candidate cell.

[0281] As an example, the above-mentioned indication information is a high probability indication (High Possibility Indicator). The high probability indication includes at least one candidate cell identifier. The high probability indication is used to indicate that the probability of the serving cell predicted by the first network device being changed to at least one first object is greater than a first preset threshold. As shown in Table 5, for example, the cell identifiers in the above-mentioned high probability indication are cell 1 and cell 3, indicating that the terminal has a high probability of accessing cell 1 and cell 3.

[0282] The above-mentioned high probability information can carry multiple cell identifiers (i.e., cell identifiers corresponding to multiple first objects) candidate cells, as shown in Table 6. The above-mentioned high probability indication can also carry TCI status information, through which the multiple candidate beams corresponding to the high probability indication can be determined.

[0283] Table 5

[0284] Table 6

[0285] As an example, the indication information is a low probability indicator, which includes at least one candidate cell identifier. The low probability indicator is used to indicate that the probability of the serving cell predicted by the first network device to change to at least one second object is lower than a first preset threshold. As shown in Table 7, the indication information can carry multiple candidate cells. As shown in Table 8, the low probability indicator can also carry TCI status information, and the TCI status information can be used to determine the multiple candidate beams corresponding to the low probability indication.

[0286] Table 7

[0287] Table 8

[0288] In the embodiment of the present disclosure, the potential conditional switching cell list may carry at least one cell identifier.

[0289] Optionally, when the first network device is a source DU and the second network device is a target DU, the sending indication information to the second network device includes:

[0290] sending the indication information to the second network device through a third network device;

[0291] Wherein, the third network device includes a centralized unit CU;

[0292] Alternatively, the third network device includes a source CU and a target CU.

[0293] Optionally, the sending the indication information to the second network device through the third network device includes:

[0294] Sending a first interface message to the third network device, where the first interface message includes the indication information;

[0295] The first interface message includes at least one of the following:

[0296] UE context modification request;

[0297] Switch notification message;

[0298] Predict handover messages.

[0299] As an example, the above-mentioned predicted switching message is a newly introduced interface message, such as a class 1 bidirectional interface message (with two processes of request and response), or a class 2 unidirectional interface message (no response message required).

[0300] Here, the first network device sends indication information to the third network device, and the third network device sends the indication information to the second network device.

[0301] For example, for an intra-CU handover scenario, the source DU sends indication information to the CU, and then the CU where the candidate cell is located sends the indication information to the target DU where the candidate cell is located through an F1 interface message.

[0302] For another example, for the switching scenario between different CUs (inter-CU), the source DU sends the indication information to the source CU, the source CU sends the indication information to the candidate CU where the candidate cell is located through the Xn interface, and then the candidate CU sends the indication information to the candidate DU through the F1 interface.

[0303] The F1 interface message in which the CU sends the indication information to the DU may enhance the current interface message, for example, UE context modification request, or may introduce a new interface message.

[0304] The CU sends the indication information to the Xn interface message of the CU where the candidate cell is located, which can enhance the current interface message, such as handover request; or introduce a new interface message.

[0305] The following describes the transmission process of the above-mentioned instruction information in conjunction with an embodiment.

[0306] Example 1: For intra-CU and inter-DU handover scenarios;

[0307] As shown in Figure 3, the process includes:

[0308] Step 0: The source DU predicts the access status based on the collected UE L1 measurement results and obtains the indication information. The actual handover decision may be made by the source CU or the UE.

[0309] Specifically, based on the collected UE L1 measurement results, the source DU discovers one or more candidate cells that are likely, unlikely, or likely to be handed over to. These candidate cells may belong to one or more candidate DUs. For example, for cells where handover is possible, the source DU discovers that the probability that the UE may handover to cell 1, cell 2, and cell 3 is 0.9, 0.6, and 0.5, respectively, and that the probability that the UE may not handover to cell 4 is 0.1. Based on this information, the above indication information is obtained.

[0310] Among them, cell 1 and cell 2 belong to candidate DU1, cell 3 and cell 4 belong to candidate DU2, and DU1, DU2 and the source DU belong to the same CU.

[0311] Step 1: The source DU notifies the CU of the indication information through the F1 interface message.

[0312] The above-mentioned F1 interface message can enhance the existing interface message, such as UE context modification request, and can also introduce a new interface message. The new interface message can be a class 1 message or a class 2 message.

[0313] This instruction information has been described in detail above and will not be repeated here.

[0314] Step 2: The CU forwards the indication information to the candidate DU via the F1 interface message.

[0315] If multiple candidate cells are received and belong to different candidate DUs, the CU can initiate F1 interface messages to different DUs. F1 interface messages can enhance existing interface messages, such as UE context modification request, or introduce new interface messages that carry indication messages. For the same candidate DU, if multiple candidate cells are involved, a single message can include multiple candidate cells and indication information, or it can carry only one candidate cell and indication information.

[0316] Step 3: The candidate DU schedules the reserved candidate cell resources according to the indication information.

[0317] Embodiment 2: For the handover scenario within the same CU and between different DUs (inter-CU and inter-DU);

[0318] Compared to Example 1, in the inter-CU scenario, an additional Xn interface process is added to transmit indication information between the two CUs and, in turn, to the candidate DU. Xn interface messages can enhance existing messages, such as handover requests, or introduce new interface messages. These carry indication information indicating that the UE may change or add a serving cell to one or more specified cells or beams.

[0319] As shown in Figure 4, the process includes:

[0320] Step 0: The source DU predicts the access status based on the collected UE L1 measurement results and obtains the indication information.

[0321] Step 1: The source DU notifies CU1 of the indication information through an F1 interface message.

[0322] The above-mentioned F1 interface message can enhance the existing interface message, such as UE context modification request, and can also introduce a new interface message. The new interface message can be a class 1 message or a class 2 message.

[0323] This instruction information has been described in detail above and will not be repeated here.

[0324] Step 2: CU1 sends the indication information to CU2 via the Xn interface message.

[0325] Step 3: CU2 forwards the indication information to the candidate DU via the F1 interface message.

[0326] Step 4: The candidate DU schedules the reserved candidate cell resources according to the indication information.

[0327] Example 3: In the inter-DU case (if an interface exists between DUs), as shown in FIG5 , the process includes:

[0328] Step 0: The source DU predicts the access status based on the collected UE L1 measurement results and obtains the indication information.

[0329] Step 1: The source DU sends the indication information to the candidate DU.

[0330] Step 2: The candidate DU schedules the reserved candidate cell resources according to the indication information.

[0331] In an embodiment of the present disclosure, before a terminal changes or adds a serving cell, an indication message is sent to a second network device; wherein the indication message includes information required by the second network device for terminal access management and / or resource management. Through the above solution, before the terminal changes or adds a serving cell, the second network device can perform terminal access management operations related to terminal access based on the indication message to reduce access latency, and / or perform resource management based on the indication message, such as releasing uplink resources or deactivating uplink resources, to avoid resource waste.

[0332] As shown in FIG6 , the embodiment of the present disclosure further provides an information processing method, which is executed by the second network device. The method includes:

[0333] Step 601: Acquire indication information sent by the first network device, where the indication information includes information required by the second network device to perform terminal access management and / or resource management.

[0336] Alternatively, the first network device is a source distributed unit DU, and the second network device is a target distributed unit DU.

[0337] Optionally, the serving cell change or addition includes at least one of the following:

[0344] Through the above scheme, before the terminal changes or adds a service cell, the second network device performs terminal access management operations related to terminal access based on the indication information to reduce access delay, and / or performs resource management based on the indication information, such as releasing or deactivating uplink resources, to avoid resource waste.

[0532] It should be noted here that the above-mentioned device provided in the embodiment of the present disclosure can implement all the method steps implemented in the information processing method embodiment performed by the above-mentioned second network device, and can achieve the same technical effect. The parts and beneficial effects of this embodiment that are the same as those in the method embodiment will not be described in detail here.

[0533] In addition, in the related art, a dedicated logical channel identity (LCID) may be used during a random access process to indicate that the device type is an enhanced reduced capability UE (eRedCap UE).

[0534] In the Rel-18 NR Non-Terrestrial Network (NTN) coverage enhancement, there is a requirement that the UE can indicate to the network during the random access process that the Physical Uplink Control Channel (PUCCH) carrying the Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) of the random access message (Msg4) needs to be repeated. In addition, the Radio Access Network (RAN) 1 sends the following Letters (LS) to RAN2:

[0535] Working hypothesis:

[0536] For PUCCH repetition of HARQ-ACK carrying Msg4, Option B is supported as the container for UE-indicated repetition request or capability report.

[0537] Option B specifically includes: higher layer signaling in the PUSCH carrying Msg3.

[0538] RAN1 hopes that RAN2 will complete the above instruction at a higher layer through higher layer signaling (for example, PUSCH carrying Msg3). Carrying the above instruction through a dedicated LCID is a solution for higher layer signaling.

[0539] We define it as follows:

[0540] Requirement 1: eRedCap UE early identification.

[0541] Requirement 2: PUCCH repetition request for Msg4 HARQ-ACK.

[0542] The subsequent description will use the above-mentioned requirements 1 and 2 as examples. However, the solutions given below are not limited to the specific requirements indicated by the above-mentioned requirements 1 or 2, and can also be applied to other requirements.

[0543] The problem is that if the eRedCap UE operates in an NTN cell, there may be a requirement that the PUCCH of the eRedCap UE's Msg4 HARQ-ACK also needs to be repeated. In this case, the eRedCap UE needs to send the above requirement 1 and the above requirement 2 to the network.

[0544] Regarding the plan, the following definition is made:

[0545] The first solution: Use the random access Msg1 solution to send indication information, such as defining a dedicated preamble or a dedicated random access occasion (RACH Occasion, RO), and the UE transmits the indication information by using the above-mentioned dedicated preamble and / or dedicated RO. The Msg1 solution here includes the case of a dedicated physical random access channel (PRACH) resource corresponding to MsgA in the two-step RACH, such as a dedicated preamble and / or a dedicated RACH occasion (RACH occasion, RO), where RO can represent the time-frequency resource of random access.

[0546] The second solution: Use the random access Msg3 solution to send indication information, for example, use Msg3 to carry a dedicated LCID, use Msg3 to carry a dedicated medium access control layer control element (MAC CE), use the reserved bit in the MAC subheader in Msg3, or the spare bit in the RRC signaling carried by Msg3, etc.

[0547] The present disclosure provides the following solutions:

[0548] If the first solution is used to transmit requirement 1, the second solution is no longer used to transmit requirement 1, and the second solution can be used to transmit requirement 2; or

[0549] If the first solution is not used for transmission requirement 1, the first solution can be used for transmission requirement 2. In this case, the second solution can be used for transmission requirement 1.

[0550] If the first solution is used to transmit Requirement 1, dedicated Msg1 resources may be configured for Requirement 1, such as a dedicated preamble and / or a dedicated RO. That is, if dedicated Msg1 resources are configured for Requirement 1, it can be considered that the first solution is used to transmit Requirement 1.

[0551] If the first solution is not used to transmit Requirement 1, it may be because: dedicated Msg1 resources are not configured for Requirement 1, such as dedicated preamble and / or dedicated RO. That is, if dedicated Msg1 resources are not configured for Requirement 1, it can be considered that the first solution is not used to transmit Requirement 1.

[0552] The program includes:

[0553] receiving first indication information, where the first indication information is used to indicate that a first requirement is transmitted using a first solution, where the first requirement is requirement 1 or requirement 2;

[0554] It is determined that a first solution is used to transmit a first requirement, and a second solution is used to transmit a second requirement, where the second requirement is requirement 1 or requirement 2, and the first requirement and the second requirement are different.

[0555] or:

[0556] receiving first indication information, where the first indication information is used to indicate that a first requirement is transmitted using a second solution, where the first requirement is requirement 1 or requirement 2;

[0557] It is determined that the first requirement is transmitted using the second solution, and the second requirement is transmitted using the first solution, where the second requirement is requirement 1 or requirement 2, and the first requirement and the second requirement are different.

[0558] The first indication information is used to indicate the use of the first solution to transmit the first demand, specifically, configuring dedicated Msg1 resources for the first demand, such as configuring a dedicated preamble and / or a dedicated RO. That is, if dedicated Msg1 resources are configured for the first demand, it can be considered that the use of the first solution to transmit the first demand is indicated.

[0559] The first indication information is used to indicate that the second solution is used to transmit the first demand. Specifically, no dedicated Msg1 resource is configured for the first demand, such as no dedicated preamble and / or dedicated RO. That is, if no dedicated Msg1 resource is configured for the first demand, it can be considered that the second solution is used to transmit the first demand.
