Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

For example, A and / or B can represent three situations: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship. In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.
[0169] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions.

Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.
[0170] Figure 1 A block diagram of a wireless communication system applicable to an embodiment of the present application is shown. The wireless communication system includes a terminal device 11 and a network side device (or network device) 12. Among them, the terminal device 11 may also be referred to as a terminal or a user terminal (User Equipment, UE). It should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present application. The network side device 12 may be a base station or a core network. It should be noted that in the embodiment of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.
[0171] In order to enable those skilled in the art to better understand the embodiments of the present application, the following description is first made.
[0172] In the related art, cell switching can only be triggered by the network side based on layer 3 (Layer 3, L3) measurement, and cell switching includes real-time switching and conditional switching.
[0173] (1) Real-time switching:
[0174] 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).
[0175] (2) Conditional switching:
[0176] CU pre-configures multiple candidate cells for UE, that is, sends the configuration information and execution conditions of the candidate cells to UE in advance. When 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, but will save the received configuration and measure and evaluate the configured candidate cells until there is a cell that meets the execution conditions. UE will 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 service cell (Primary cell, PCell) or PSCell. After the UE successfully accesses, it will feedback the reconfiguration completion message to the network.
[0177] In the related technology, the cell change mechanism based on L1 / L2 command will be supported. The cell change mechanism based on L1 / L2 command implements a faster process than the one based on L3 command. At the same time, the cell change mechanism based on L1 / L2 command is not limited to switching and PSCell change, but can also be applied to secondary cells (SCell). To support mobility based on L1 / L2 command, CU needs to request the configuration information of candidate cell from candidate DU in advance, and pre-configure this information to UE in advance through RRC message. UE performs L1 measurement on neighboring cells according to the received configuration and reports it to serving DU. Serving DU makes switching decision based on measurement report.
[0178] The information processing method provided by the embodiment of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.
[0179] like Figure 2 As shown, an embodiment of the present application provides an information processing method, which is executed by a first network device, and the method includes:
[0180] Step 201: Sending instruction information to a second network device;
[0181] The indication information includes information required by the second network device to perform terminal access management and / or resource management.
[0182] Optionally, before the terminal changes or adds a serving cell, indication information is sent to the second network device.
[0183] In the embodiment of the present application, the first network device is a source base station, and the second network device is a candidate base station;
[0184] Alternatively, the first network device is a source distributed unit DU, and the second network device is a target distributed unit DU.
[0185] Optionally, the serving cell change or addition includes at least one of the following:
[0186] The primary serving cell (PCell) is changed. The PCell can also be the primary serving cell of the primary cell group (in the dual connectivity scenario);
[0187] Cell switching;
[0188] Change of primary and secondary cells (Primary SCG Cell, PSCell);
[0189] PSCell added.
[0190] 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 indication information to the second network device, so that the second network device can perform terminal access management operations and / or resource management operations. That is, the above indication information is sent after measuring the candidate cell and before changing or adding the serving cell.
[0191] 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 may be uplink resource release or resource deactivation operations to avoid resource waste.
[0192] Optionally, the terminal access management operation includes an uplink resource scheduling operation and / or a beam angle adjustment operation.
[0193] In an embodiment of the present application, the first network device may determine whether to change or add a service 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 the terminal determines whether to change or add a service cell.
[0194] Optionally, the indication information includes at least one of the following:
[0195] a first probability, wherein the first probability information is used to indicate a probability that the serving cell predicted by the first network device is changed to at least one candidate cell or to indicate a probability that the beam of the serving cell is changed to a candidate beam of at least one candidate cell predicted by the first network device;
[0196] a second probability, wherein 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 is used to indicate 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;
[0197] 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, where the first object includes 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;
[0198] 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 satisfy the first switching condition, or the second probability corresponding to the second object does not satisfy the second switching condition.
[0199] Optionally, the first switching condition includes a first probability greater than or equal to a first preset threshold, and the second switching condition includes a second probability greater than or equal to a second preset threshold.
[0200] In the embodiment of the present application, the first probability and the second probability may be specifically integers. For example, the larger the value of the first probability is, the higher the probability is. For example, the first probability and the second probability are expressed in the form of INTEGER (1, ..., 100) respectively.
[0201] In the embodiment of the present application, only the first probability or the 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. Only the second probability or the second object indication information may be carried to indicate that the candidate cell corresponding to the second network device may not be accessed, and there is no need to reserve uplink resources, or temporarily deactivate uplink resources. The first probability or the first object indication information and the second probability or the second object indication information may also be carried at the same time, that is, the candidate cells or candidate beams with high switching probabilities and low switching probabilities are indicated at the same time.
[0202] As an example, in the case where 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.
[0203] 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.
[0204] Optionally, the indication information further includes at least one of the following:
[0205] 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 through the TCI status information;
[0206] 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;
[0207] Terminal identification;
[0208] Serving cell identifier;
[0209] an identification of one or more candidate cells;
[0210] 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.
[0211] As an example, the above indication information may include a list, as shown in Table 1, including identifiers of multiple candidate cells and corresponding switching probabilities.
[0212] Table 1
[0213]
[0214] The IE structure corresponding to the above Table 1 is shown in Table 2:
[0215] Table 2
[0216]
[0217]
[0218] in, <max>Indicates the maximum number of candidate cells in the candidate DU.
[0219] In addition to carrying the candidate cell identifier, the corresponding TCI status information may also be carried, as shown in Table 3.
[0220] Table 3
[0221]
[0222] The IE structure corresponding to the above Table 3 is shown in Table 4:
[0223] Table 4
[0224]
[0225] The above example describes the case where the indication information carries multiple candidate cells. In the embodiment of the present application, the indication information may also carry only one candidate cell. That is, the indication information includes a candidate cell identifier, a switching probability corresponding to the candidate cell identifier, such as the IE structure shown in Table 2. At this time, the potential conditional switching 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. At this time, the potential conditional switching cell list carries one candidate cell.
[0226] As an example, the above indication information is a high probability indication (High possibility Indicator). The high probability indication includes at least one candidate cell identifier, and the high probability indication is used to indicate that the probability of the service cell predicted by the first network device to change to at least one first object is higher than the first preset threshold. As shown in Table 7, for example, the cell identifiers in the above high probability indication are cell 1 and cell 3, indicating that the probability of the terminal accessing cell 1 and cell 3 is relatively high.
[0227] 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 8. The above-mentioned high probability indication can also carry TCI status information, and the multiple candidate beams corresponding to the high probability indication can be determined through the TCI status information.

[0232] As an example, the above indication information is a low probability indication ( low The low probability indication includes at least one candidate cell identifier, and the low probability indication is used to indicate that the probability of the service 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 9, the above indication information can carry multiple candidate cells. As shown in Table 10, the above low probability indication can also carry TCI state information, and the multiple candidate beams corresponding to the low probability indication can be determined through the TCI state information.

[0236]
[0237] In the embodiment of the present application, the potential conditional switching cell list may carry at least one cell identifier.
[0238] 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:
[0239] Sending the indication information to the second network device through a third network device;
[0240] Wherein, the third network device includes a centralized unit CU;
[0241] Alternatively, the third network device includes a source CU and a target CU.
[0242] Optionally, sending the indication information to the second network device through the third network device includes:
[0243] Sending a first interface message to the third network device, where the first interface message includes the indication information;
[0244] The first interface message includes at least one of the following:
[0245] Terminal context update request (UE context modification required);
[0246] Switch notification message;
[0247] Predict handover messages.
[0248] 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 is required).
[0249] 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.
[0250] For example, for an intra-CU switching 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.
[0251] 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 the candidate CU then sends the indication information to the candidate DU through the F1 interface.
[0252] The F1 interface message in which the CU sends the indication information to the DU may enhance the current interface message, for example, UEcontext modification request, or may introduce a new interface message.
[0253] 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 a handover request; or introduce a new interface message.
[0254] The transmission process of the above indication information is described below in conjunction with an embodiment.
[0255] Embodiment 1: for intra-CU and inter-DU switching scenarios;
[0256] like Figure 3 As shown, the process includes:
[0257] 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 by the UE.
[0258] Specifically, the source DU finds one or more candidate cells that may / may not / have a high probability of switching based on the collected UE L1 measurement results. These candidate cells may belong to one or more candidate DUs. Taking the cells that may be switched as an example, the source DU finds that the probability that the UE may switch to cell 1, cell 2 and cell 3 is 0.9, 0.6 and 0.5 respectively, and the probability that it may not switch to cell 4 is 0.1. Based on the above information, the above indication information is obtained.
[0259] Among them, cell 1 and cell 2 belong to candidate DU1, cell 3 and cell 4 belong to candidate DU2, and DU1, DU2 and source DU belong to the same CU.
[0260] Step 1: The source DU notifies the CU of the indication information via the F1 interface message.
[0261] The above-mentioned F1 interface message can enhance the existing interface message, such as UE context modification required, or introduce a new interface message, and the new interface message can be a class 1 message or a class 2 message.
[0262] The instruction information has been described in detail above and will not be repeated here.
[0263] Step 2: The CU forwards the indication information to the candidate DU via the F1 interface message.
[0264] If the received multiple candidate cells belong to different candidate DUs, the CU can initiate F1 interface messages to different DUs. The F1 interface message can enhance the existing interface message, such as UE context modification request, or introduce a new interface message to carry the indication message. For the same candidate DU, if multiple candidate cells are involved, one message can cover multiple candidate cells and indication information, or it can carry only one candidate cell and indication information.
[0265] Step 3: The candidate DU schedules the reserved candidate cell resources according to the indication information.
[0266] Embodiment 2: For the switching scenario within the same CU and between different DUs (inter-CU and inter-DU);
[0267] Compared with the first embodiment, in the case of inter-CU, an Xn interface process is added to transmit the indication information between the two CUs and then pass it to the candidate DU. The Xn interface message can enhance the current message, such as handover request, or introduce a new interface message. Carrying indication information, it is used to indicate that the UE may change the serving cell / add to the specified one or more cells / beams.
[0268] like Figure 4 As shown, the process includes:
[0269] Step 0: The source DU predicts the access status based on the collected UE L1 measurement results and obtains the indication information.
[0270] Step 1: The source DU notifies CU1 of the indication information via an F1 interface message.
[0271] The above-mentioned F1 interface message can enhance the existing interface message, such as UE context modification required, or introduce a new interface message, and the new interface message can be a class 1 message or a class 2 message.
[0272] The instruction information has been described in detail above and will not be repeated here.
[0273] Step 2: CU1 sends the indication information to CU2 via the Xn interface message.
[0274] Step 3: CU2 forwards the indication information to the candidate DU via the F1 interface message.
[0275] Step 4: The candidate DU schedules the reserved candidate cell resources according to the indication information.
[0276] Embodiment 3: In the inter DU case (if there is an interface between DUs), such as Figure 5 As shown, the process includes:
[0277] Step 0: The source DU predicts the access status based on the collected UE L1 measurement results and obtains the indication information.
[0278] Step 1: The source DU sends the indication information to the candidate DU.
[0279] Step 2: The candidate DU schedules the reserved candidate cell resources according to the indication information.
[0280] In an embodiment of the present application, before the terminal changes or adds a serving cell, an indication message is sent to the second network device; wherein the indication message includes information required for the second network device to perform terminal access management and / or resource management. Through the above scheme, the second network device can perform terminal access management operations related to terminal access based on the indication message before the terminal changes or adds a serving cell, so as to reduce access delay, and / or perform resource management based on the indication message, such as releasing uplink resources or deactivating uplink resources, so as to avoid resource waste.

[0481] It should be noted here that the above-mentioned device provided in the embodiment of the present application 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 the method embodiment will not be described in detail here.
[0482] 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).
[0483] In the coverage enhancement of Rel-18 NR non-terrestrial network (NTN), 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 LS to RAN2:
[0484] Working hypothesis:
[0485] For PUCCH repetition of HARQ-ACK carrying Msg4, Option B is supported as a container for UE-indicated repetition request or capability report.
[0486] Option B specifically includes: higher layer signaling in the PUSCH carrying Msg3.
[0487] RAN1 hopes that RAN2 will complete the above instruction at a high level through high-level signaling (for example, PUSCH carrying Msg3). Carrying the above instruction through a dedicated LCID is a high-level signaling solution.
[0488] We define it as follows:
[0489] Requirement 1: eRedCap UE early identification.
[0490] Requirement 2: PUCCH repetition request for Msg4 HARQ-ACK.
[0491] The subsequent description will take the above-mentioned requirement 1 and requirement 2 as examples, but the subsequent solutions are not limited to the specific requirements indicated by the above-mentioned requirement 1 or requirement 2, and can also be applied to other requirements.
[0492] The problem is that if the eRedCap UE works in the NTN cell, there is a possible requirement that the PUCCH of the eRedCap UE's Msg4 HARQ-ACK also needs to be repeated. At this time, the following requirements exist: the eRedCap UE needs to send the above requirement 1 to the network, and also needs to send the above requirement 2 to the network.
[0493] Regarding the plan, the following definition is made:
[0494] The first scheme: Use the random access Msg1 scheme 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 dedicated preamble and / or dedicated RO. The Msg1 scheme here includes the case of dedicated PRACH resources corresponding to MsgA in the two-step RACH, such as dedicated preamble and / or dedicated RO (RACH occasion, random access time-frequency resources).
[0495] The second solution: use the random access Msg3 solution to send indication information, for example, use a dedicated LCID carried in Msg3, use a dedicated MAC CE carried in Msg3, use a reserved bit in the MAC subheader in Msg3, or a spare bit in the RRC signaling carried by Msg3, etc.
[0496] This application provides the following solutions:
[0497] If the first solution is used to transmit demand 1, the second solution is no longer used to transmit demand 1, and the second solution can be used to transmit demand 2; or
[0498] 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.
[0499] If the first solution is used to transmit demand 1, dedicated Msg1 resources may be configured for demand 1, such as dedicated preamble and / or dedicated RO. That is, if dedicated Msg1 resources are configured for demand 1, it can be considered that the first solution is used to transmit demand 1.
[0500] If the first solution is not used to transmit demand 1, it may be that: no dedicated Msg1 resource is configured for demand 1, such as no dedicated preamble and / or dedicated RO. That is, if no dedicated Msg1 resource is configured for demand 1, it can be considered that the first solution is not used to transmit demand 1.
[0501] The program includes:
[0502] 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;
[0503] 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.
[0504] or:
[0505] 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;
[0506] 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.
[0507] The first indication information is used to indicate that the first requirement is transmitted using the first solution, specifically, configuring a dedicated Msg1 resource for the first requirement, such as configuring a dedicated preamble and / or a dedicated RO. That is, if a dedicated Msg1 resource is configured for the first requirement, it can be considered that the first requirement is transmitted using the first solution.
[0508] The first indication information is used to indicate that the second solution is used to transmit the first requirement, specifically, no dedicated Msg1 resource is configured for the first requirement, such as no dedicated preamble and / or dedicated RO is configured. That is, if no dedicated Msg1 resource is configured for the first requirement, it can be considered that the second solution is used to transmit the first requirement.
