[0032] To help those skilled in the art better understand the technical solutions of the embodiments of the present disclosure, the technical solutions of the present disclosure will be clearly and completely described below in conjunction with the drawings in the present disclosure. Obviously, the embodiments described are only some of the embodiments of the present disclosure, not all of them. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0033] It should be noted that in this disclosure, words such as "exemplarily" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this disclosure as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplarily" or "for example" is intended to present the relevant concepts in a concrete manner.

[0034] In the following, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features being referred to. Therefore, a feature defined with the terms "first," "second," etc., may explicitly or implicitly include one or more of such features.

[0035] In the description of this disclosure, unless otherwise specified, " / " means "or." For example, A / B can mean A or B. "And / or" herein is merely a description of an association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: only A, only B, and both A and B. Furthermore, "at least one" means one or more, and "a plurality" means two or more.

[0036] The methods provided in the embodiments of the present disclosure can be applied to various communication systems. For example, the communication system can be a fifth-generation (5G) communication system, a Wi-Fi (Wireless Fidelity) system, a 3GPP (3rd Generation Partnership Project)-related communication system, a future-evolved communication system (such as a sixth-generation (6G) communication system), or a system integrating multiple systems, and the embodiments of the present disclosure are not limited thereto.

[0037] The network architecture of the communication network (including but not limited to 3G, 4G, 5G and future mobile communication networks) in the embodiments of the present disclosure may include at least a first node and a second node. In this example, the first node may be a terminal-side device (for example, including but not limited to a terminal), and the second node may be a network-side device (for example, including but not limited to a base station).

[0038] For example, taking the first node as a terminal and the second node as a base station, as shown in Figure 1, Figure 1 shows a communication system provided by an embodiment of the present disclosure. The communication system includes a terminal 110 and a base station 120. The terminal 110 is in communication connection with the base station 120.

[0039] In some embodiments, there may be one or more base stations 120 and one or more terminals 110, and the embodiments of the present disclosure do not limit the number.

[0040] The terminal 110 may determine a target cell to be accessed, and access the target cell based on the configuration information of the access resources of the target cell.

[0041] In some embodiments, the access resource configuration information includes physical random access channel (PRACH) resource information, or adaptive configuration of the access resource. For example, the adaptive configuration information of the access resource includes periodic configuration, multiple sets of access resource configurations, and configurations for using different access resources in different periods. The access resource can change dynamically according to the period.

[0042] In some embodiments, the terminal 110 may receive access information broadcasted by the base station 120, such as SIB information, and determine configuration information of access resources of the first type of cell based on the SIB information, and then access the target cell.

[0043] Exemplarily, terminal 110 may receive access information on a first-type cell. The access information includes configuration information of access resources of a second-type cell associated with the first-type cell. The second-type cell associated with the first-type cell includes a target cell. In this case, terminal 110 may access the target cell based on the configuration information of the access resources of the second-type cell in the access information.

[0044] In some embodiments, the terminal 110 receives access information sent by the base station 120 and accesses the target cell according to the access information.

[0045] In some embodiments, the terminal 110 may also send a first signaling to the base station 120 and receive a second signaling from the base station 120 in response to the first signaling, so as to determine the configuration information of the access resources of the target cell based on the second signaling and access the target cell.

[0046] In some embodiments, the second signaling may indicate an access resource index in the adaptive configuration of the access resource, each access resource index corresponding to a set of access resources.

[0047] Exemplarily, the terminal may be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. The embodiments of the present disclosure do not limit the application scenarios. The terminal may also sometimes be referred to as a user, user equipment (UE), access terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal, mobile device, UE terminal, wireless communication device, UE agent or UE device, etc., which is not limited in the embodiments of the present disclosure.

[0048] The base station 120 is used to receive the signaling sent by the core network and broadcast the signaling according to the configuration in the signaling.

[0049] In some embodiments, the coverage of base station 120 includes at least one cell. For example, the coverage of base station 120 includes a first type cell and a second type cell. Base station 120 may send access information on the first type cell and / or send access information on the second type cell. The first type cell may be an anchor cell, and the second type cell may be a non-anchor cell.

[0050] It should be noted that some network energy saving (NES) operations, such as SIB-less operations, may be used or performed on non-anchor cells. Based on the SIB-less operation, the base station 120 does not send SIB1 (system information block 1, system information block type 1) or does not send SIBs on the non-anchor cell; or, there is no SIB1 or no SIB on the non-anchor cell; or, there is a lack of SIB1 or SIBs on the non-anchor cell. When SIB-less is used on the non-anchor cell, the SIB information of the non-anchor cell can be received on the anchor cell, that is, the base station 120 can send the SIB information of the non-anchor cell on the anchor cell.

[0051] It should be noted that the anchor cell, non-anchor cell, cell, first type cell, or second type cell mentioned in the embodiments of the present disclosure does not only represent a cell, but can also represent one or more frequency domain resources, such as one or more carriers, one or more bandwidths, one or more bandwidth parts, one or more frequency bands, etc.

[0052] For example, the anchor cell may be a primary cell, and the non-anchor cell may be a secondary cell. Alternatively, the anchor cell may be one carrier, and the non-anchor cell may be another carrier. Alternatively, the anchor cell may be a group of carriers, and the non-anchor cell may be another group of carriers. Alternatively, the anchor cell may be one bandwidth, and the non-anchor cell may be another bandwidth. Alternatively, the anchor cell may be one bandwidth portion, and the non-anchor cell may be another bandwidth portion. Alternatively, the anchor cell may be one bandwidth portion, and the non-anchor cell may be another bandwidth portion. The embodiments of the present disclosure are not limited in this regard. For ease of description and consistency, the following description uses cells as the basis.

[0053] In some embodiments, the first type of cell is a cell where the terminal camped before camping on the second type of cell.

[0054] In some embodiments, the coverage areas of the first type of cells and the second type of cells overlap.

[0055] In some embodiments, the first type of cell is a group of carriers, the second type of cell is another group of carriers, and the frequency difference between the two groups of carriers does not exceed a first threshold. Exemplarily, the first threshold is greater than or equal to 0 and less than or equal to 1 GHz, 2 GHz, 3 GHz, 4 GHz, or 5 GHz.

[0056] In some embodiments, the first type of cell is one set of bandwidths, the second type of cell is another set of bandwidths, and the frequency difference between the two sets of bandwidths does not exceed a second threshold. Exemplarily, the second threshold is greater than or equal to 0 and less than or equal to 1 GHz, 2 GHz, 3 GHz, 4 GHz, or 5 GHz.

[0057] In some embodiments, when a terminal requests access to a target cell, base station 120 may further, after receiving first signaling from terminal 110, send second signaling to terminal 110 in the target cell or a first-type cell associated with the target cell. The first signaling is used to request configuration information of access resources of the target cell. The second signaling includes configuration information of access resources of the target cell.

[0058] In some embodiments, the first signaling is uplink wake-up signaling, such as wake-up signal (WUS) signaling.

[0059] In some embodiments, the base station can be a base station or an evolved base station (eNB or eNodeB) in long term evolution (LTE), long term evolution advanced (LTEA), a base station device in a 5G network, or a base station in a future communication system, etc. The base station may include various macro base stations, micro base stations, home base stations, wireless remote stations, reconfigurable intelligent surfaces (RISs), routers, relays, wireless fidelity devices and other network side devices.

[0060] It should be noted that the above scenarios are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Ordinary technicians in this field can know that with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0061] In communication systems, base stations are key nodes connecting user devices and communication networks. With the widespread application of technologies such as massive antennas and large bandwidth, the energy consumption problem of base stations has gradually become prominent. To solve this problem, green communication and base station power saving technologies have become research hotspots. Reducing the transmission of common signals / signaling (such as SIB information) by base stations and putting them into a dormant state when they do not need to send signals / signaling can save base station energy consumption. Based on the above-mentioned means of saving base station energy consumption, some base stations may choose not to send common signals / signaling (such as SIB information) to achieve network energy saving. However, reducing the transmission of common signals / signaling may affect system performance and have an impact on system capacity, etc. Therefore, which signals / signaling can be reduced and how to reduce or eliminate the impact on the system requires further research.

[0062] For example, when a terminal accesses a base station (e.g., a cell covered by the base station), it typically needs to receive SIB information, SIB1 information, other SIB information, paging information, and random access channel (RACH) information on the cell to access the cell. However, for a non-anchor cell that uses SIB-less, the terminal cannot receive SIB information, and thus cannot access the non-anchor cell, affecting normal access of the terminal.

[0063] To address the above issues, see Figure 2, which is a flow chart of a cell access method provided by an embodiment of the present disclosure. As shown in Figure 2, the cell access method provided by an embodiment of the present disclosure is applied to a first node and includes the following S101-S102.

[0064] S101: Determine a target cell to be accessed.

[0065] In some embodiments, the type of cell may include a first type cell and a second type cell.

[0066] In some embodiments, the first type of cell is a cell in which the power saving function is not enabled. The second type of cell is a cell in which the power saving function is enabled.

[0067] In some embodiments, the first type of cell is a cell that transmits SIB1 or SIB. The second type of cell is a cell that does not transmit SIB1 or SIB.

[0068] In some embodiments, the first type of cell may be referred to as an anchor cell, and the second type of cell may be referred to as a non-anchor cell, which is not limited.

[0069] In some embodiments, a first type cell is associated with one or more second type cells. The terminal can obtain access information of the first type cell and the second type cell on the first type cell. When a first node (e.g., a terminal) needs to access a target cell, it can determine the target cell to be accessed from multiple cells based on the access information of multiple cells. Exemplarily, the first node can determine the target cell that meets the current access scenario from multiple cells based on the signal strength, coverage, etc. in the access information of multiple cells.

[0070] In some embodiments, the access information may be indicated by a single signaling or by multiple different signaling instructions. As an example, the access information includes configuration information and access parameters for access resources of the first type cell and the second type cell. The configuration information for the access resources of the first type cell and the second type cell is indicated by the SIB1 or SIBs of different cells, and the access parameters are indicated by the SIB1 of the first type cell.

[0071] In some embodiments, the access parameter includes at least one of the following: access weight, access priority, access selection mode, terminal identification (ID), and terminal group identification.

[0072] As an example, an access weight can be the priority of a first node in obtaining resources when competing for limited wireless resources. When multiple first nodes simultaneously request access to the wireless network, the base station needs to determine which first nodes can obtain higher priority and resource allocation based on a certain strategy. The access weight can be used to distinguish and sort the access requests of different first nodes. A higher access weight indicates that the first node has a higher access priority and can more easily obtain resource allocation. Conversely, a lower access weight indicates that the first node has a lower access priority and may have fewer opportunities to obtain resources.

[0073] As another example, the access weight can also be a value used to calculate the priority of candidate cells when selecting an access cell. For example, when there are multiple candidate cells, the measurement results of the candidate cells need to be multiplied by the corresponding access weight, and the resulting value is used to select the final target cell. The higher the access weight, the higher the priority.

[0074] In some embodiments, different cells have different access rights.

[0075] In some embodiments, a cell may have multiple access rights, corresponding to different bandwidths or carriers or frequency bands of the cell.

[0076] In some embodiments, the access weight is related to the candidate cell priority.

[0077] The access selection mode refers to the method and strategy used by the first node to access the network. Exemplary access selection modes include random access, frequency division multiplexing, signal quality-based access, target cell selection based on measurement results or thresholds, target cell selection based on signaling instructions, and target cell selection based on access parameters. Different access selection modes may be used individually or in combination, and are not limited in the present disclosure.

[0078] As another example, the access information includes configuration information of access resources for the first type cell and the second type cell, and an indication of the second type cell associated with the first type cell. The configuration information of the access resources for the first type cell and the second type cell is indicated by SIB1 of different cells. In some embodiments, the indication of the second type cell associated with the first type cell is indicated by signaling in core network or non-access stratum (NAS) signaling.

[0079] In some embodiments, the first node may identify the first type of cell and the second type of cell associated with the first type of cell based on different ways. As an example, the base station does not send information (e.g., SIB1 information) on the second type of cell, and the first node may receive information of the first type of cell (e.g., SIB1 information or master information block (MIB) information) and information of one or more second type of cells on the first type of cell. Exemplarily, the information of the first type of cell is configured with an ID or PCI of the second type of cell associated with the first type of cell. The ID or PCI of the second type of cell associated with the first type of cell is in a list. Alternatively, the information of the first type of cell is configured with an identification ID or physical cell identifier (PCI) of the second type of cell associated with the first type of cell. The ID or PCI of the second type of cell associated with the first type of cell is associated with the configuration information of the access resources of the second type of cell.

[0080] As another example, the first node may obtain an indication of a first type cell and a second type cell associated with the first type cell through core network signaling or NAS signaling. For example, core network signaling may indicate whether a cell is a first type cell or a second type cell. For a second type cell, core network signaling may indicate the first type cell associated with it. Alternatively, for a first type cell, core network signaling may indicate the second type cell associated with it.

[0081] As another example, the association relationship between the first type cell and the second type cell is predefined. For example, the association can be performed based on the cell ID or PCI. Exemplarily, one or more cells with specific IDs or PCIs can be predefined as the first type cell or the second type cell.

[0082] S102: Access the target cell based on the configuration information of the access resources of the target cell.

[0083] In some embodiments, after the first node determines the target cell to be accessed, it needs to obtain configuration information of the access resources of the target cell in order to access the target cell. Exemplarily, the configuration information of the access resources includes at least one of the following: information used by the first node for random access, the location of the random access resources, and preamble configuration information. The first node can perform network setup and connection based on the above information to access the target cell.

[0084] As an example, the first node may send Msg1, Msg3, or MsgA to the base station at the location of the random access resource for initial access.

[0085] As another example, the first node may receive Msg2, Msg4, or MsgB sent by the base station at the location of the random access resource.

[0086] In some embodiments, the configuration information of the access resource may be information in SIB1.

[0087] In some embodiments, the configuration information for each access resource is associated with a cell. For example, the configuration information for each access resource or group of access resources can be associated with a cell identifier or PCI of a cell. Alternatively, the configuration information for each access resource or group of access resources can be sent via different signaling (e.g., SIB1), with different signaling associated with different cells. Each cell has corresponding access resource configuration information.

[0088] In some embodiments, the first node may further obtain a configuration information list including configuration information of access resources of one or more non-anchor cells (e.g., second-type cells), and the first node may determine a target cell from the non-anchor cells and access the target cell.

[0089] In some embodiments, after the first node accesses the target cell, if the target cell is a non-anchor cell, the target cell is switched to an anchor cell, that is, the SIB-less or energy-saving operation of the target cell is disabled, and the target cell is converted to a normal cell.

[0090] In some embodiments, when the target cell accessed by the first node is a non-anchor cell, the first type cell associated with the non-anchor cell does not need to send access information of the target cell.

[0091] In some embodiments, the above method further includes: receiving access information on the first type of cell.

[0092] The access information includes configuration information of access resources of a second type cell (ie, non-anchor cell) associated with a first type cell (ie, anchor cell), and the first type cell and the second type cell associated with the first type cell include a target cell.

[0093] In some embodiments, the access information further includes at least one of the following:

[0094] Configuration information of access resources of the first type of cell;

[0095] an indication of a second type of cell associated with the first type of cell;

[0096] an indication of cells to which access is permitted;

[0097] Indication of cells to which access is denied;

[0098] Access parameters.

[0099] In some embodiments, the content of the configuration information of the access resources of the first type of cell can refer to the description of the configuration information of the access resources of the above-mentioned target cell, and the embodiments of the present disclosure will not be repeated here.

[0100] It is understandable that based on the cell access method provided by the embodiment of the present disclosure, after determining the target cell to be accessed, the first node does not need to wait for the target cell to send a public signal / signaling (e.g., SIB information) before accessing, but can directly access the target cell based on the configuration information of the access resource of the target cell. This avoids the problem of access failure caused by the first node waiting for the public signal / signaling, ensures the normal access of the first node, and reduces the risk of access failure of the first node.

[0101] In some embodiments, as shown in FIG3 , the above method further includes: S201 - S202 .

[0102] S201: Receive access information on a first type of cell.

[0103] The access information (eg, SIB1 information) includes configuration information of system information of a second type cell associated with a first type cell, and the first type cell or the second type cell includes a target cell.

[0104] In some embodiments, when a first type cell (i.e., an anchor cell) has an indication of a second type cell (i.e., a non-anchor cell associated with the anchor cell), the first node may receive access resource configuration information for the first type cell and system information configuration information for the second type cell when receiving access information for the first type cell.

[0105] S202: Receive the system information of the target cell in the target cell based on the configuration information of the system information of the target cell.

[0106] The system information of the target cell includes configuration information of access resources of the target cell.

[0107] In some embodiments, before accessing the target cell, the first node may receive system information (eg, SIB1 information) of the target cell, ie, receive configuration information of access resources of the target cell, to facilitate access to the target cell.

[0108] In some embodiments, the periodicity of the SIB1 information on the second type of cell is greater than the periodicity of the SIB1 information on the first type of cell.

[0109] In some embodiments, the base station sends configuration information of part of the access resources on the second type cell.

[0110] In some embodiments, the first node receives configuration information of access resources corresponding to the target cell, that is, receives SIB1 information corresponding to the target cell.

[0111] In some embodiments, the access information further includes at least one of the following:

[0112] Reference signal configuration of the second type cell;

[0113] Synchronization signal block configuration of the second type of cell;

[0114] downlink carrier position of the second type cell;

[0115] downlink frequency of the second type of cell;

[0116] Frequency and / or carrier position of the uplink WUS of the second type cell;

[0117] Access parameters.

[0118] In some embodiments, the access information received on the first type cell is indicated by SIB1 of the first type cell and / or the second type cell.

[0119] In some embodiments, if the first node is indicated with cells prohibited / allowed for access, the first node can only select a target cell for access from the cells allowed for access.

[0120] It can be understood that the method provided by the embodiment of the present disclosure receives access information on the first type of cell, and based on the configuration information of the system information of the target cell, receives the system information of the target cell on the target cell. When the target cell does not send a public signal / signaling (for example, when access information is sent), the first node can obtain relevant information of the target cell from the first type of cell in a timely manner to ensure normal access of the first node.

[0121] In some embodiments, as shown in FIG4 , the above method further includes: S301 - S302 .

[0122] S301: Send first signaling in a target cell or a first type cell associated with the target cell.

[0123] The first signaling is used to request configuration information of access resources of the target cell.

[0124] In some embodiments, when there is access information on the first type cell, but the access information does not include configuration information of access resources of the second type cell (i.e., the target cell), the first node will send a first signaling to the base station to request the configuration information of the access resources of the target cell.

[0125] In some embodiments, if the second type cell is not associated with the first type cell and there is no configuration information of access resources in the second type cell, the first node sends a first signaling to the base station to request configuration information of access resources of the target cell.

[0126] In some embodiments, the first signaling is an uplink wake-up signaling.The first signaling is sent on a first-type cell or a second-type cell to be accessed (ie, a target cell).

[0127] As an example, the first signaling may be low-power WUS signaling, used to wake up the base station, or request SIB1, or request a synchronization signal block (SSB), or request access resource information of a target cell.

[0128] As another example, the first signaling may be a preamble (initial access message Msg1). The preamble is for a first-type cell. The first node sends the preamble on the first-type cell, and the base station may determine the content that the first node intends to request. For example, one or more predefined preambles correspond to different second-type cells. The first node sends the corresponding preamble, indicating that the first node is requesting configuration information for access resources corresponding to the second-type cell.

[0129] As another example, the first signaling may be a preamble of the second type of cell, where the preamble of the second type of cell is a predefined preamble, and the preamble of the second type of cell is access information. The first node may send the predefined preamble of the second type of cell on the second type of cell. The predefined preamble indicates that the first node requests complete / all configuration information of access resources of the second type of cell.

[0130] As another example, the first signaling may be an initial access message Msg3 of a first type of cell, and Msg3 includes configuration information for requesting access resources of a second type of cell.

[0131] As another example, the first signaling may be an initial access message MsgA of the first type of cell.

[0132] In some embodiments, the sending location of the first signaling is indicated in the access information. The access information includes SIB1 of the first type or the second type of cell.

[0133] In some embodiments, the access information is indicated by signaling in the core network or NAS.

[0134] In some embodiments, the sending location of the first signaling may also be predefined.

[0135] In some embodiments, the access information further includes at least one of the following:

[0136] an indication of cells to which access is permitted;

[0137] Indication of cells where access is prohibited;

[0138] Reference signal configuration of the second type cell;

[0139] Synchronization signal block configuration of the second type of cell;

[0140] Access measurement threshold;

[0141] downlink carrier position of the second type cell;

[0142] Configuration information of system information of the second type of cell.

[0143] In some embodiments, the access measurement threshold is predefined, and the access measurement thresholds of different cells may be different.

[0144] In some embodiments, the access information further includes: an uplink resource location for sending the first signaling, and / or a downlink resource location for receiving configuration information of the access resource.

[0145] S302: Receive second signaling in a target cell or a first-type cell associated with the target cell.

[0146] The second signaling includes configuration information of access resources of the target cell.

[0147] In some embodiments, after requesting configuration information of access resources for a second-type cell (i.e., a target cell), the first node needs to monitor (or receive) signaling within a certain period of time, i.e., receive second signaling on the target cell or the first-type cell, and access the target cell based on the configuration information of the access resources of the target cell in the second signaling. The second signaling indicates at least one of the following: a cell ID, a PCI, a PCI list, a cell ID list, and whether the cell is accessible.

[0148] In some embodiments, the second signaling is indicated by at least one of SSB, MIB, paging downlink control information (paging DCI), paging, physical downlink shared channel (PDSCH), paging early indication (PEI), low power (LP) WUS, system information-radio network temporary identifier (SI-RNTI) scrambled DCI, and SIB.

[0149] In some embodiments, the second signaling includes an index of the access resource. In some embodiments, the second signaling includes a time-frequency domain location of the access resource. In some embodiments, the second signaling includes a period of the access resource. In some embodiments, the second signaling indicates a change value of the access resource. In some embodiments, the second signaling indicates a subcarrier spacing (SCS) of the access resource.

[0150] In some embodiments, the above method further includes: receiving access information, the access information including: transmission resource configuration of the first signaling and / or transmission resource configuration of the second signaling.

[0151] It is understandable that when the access information on the first type of cell does not include the configuration information of the access resources of the target cell, the first node can promptly send a first signaling to request the configuration information of the access resources of the target cell, so that the first node can normally access the target cell and use network services based on the configuration information of the access resources of the target cell. Alternatively, when the second type of cell is not associated with the first type of cell, the first node can promptly send a first signaling to request the configuration information of the access resources of the target cell, so that the first node can normally access the target cell and use network services based on the configuration information of the access resources of the target cell. In some embodiments, the second type of cell not being associated with the first type of cell indicates a second type of cell, and the second type of cell is an independent cell, and the relevant information of the cell is not transmitted on other cells.

[0152] In some embodiments, the first type of cell is a coverage cell.

[0153] In some embodiments, the second type cell is a SIB1-less cell, and before camping on the second type cell, the first node obtains, on a coverage cell (e.g., the first type cell), configuration information related to an uplink WUS of the second type cell, or an indication of a coverage cell associated with the second type cell (e.g., the first type cell). Exemplarily, the configuration information related to an uplink WUS of the second type cell or the indication of a coverage cell associated with the second type cell obtained by the first node on the coverage cell (e.g., the first type cell) is sent by the core network or the NAS.

[0154] In some embodiments, the second type cell is an independent cell, and relevant information of the second type cell (for example, configuration information of uplink WUS, etc.) is sent in other cells, but the second type cell is not associated with the cell that sends its relevant information (for example, configuration information of uplink WUS, etc.).

[0155] In some embodiments, the above S101 may be implemented as: determining a target cell according to access information.

[0156] In some embodiments, determining the target cell based on the access information may be implemented by selecting a cell with the best measurement result as the target cell. The measurement result may be used as access information.

[0157] In some embodiments, the first node measures the SSB or reference signal of the first type of cell (i.e., anchor cell) and the second type of cell (i.e., non-anchor cell), and selects the cell with the best measurement result or the highest measurement value as the target cell.

[0158] In some embodiments, the above-mentioned determination of the target cell based on the access information can be implemented as follows: S401-S402, as shown in FIG5 .

[0159] S401: Determine candidate cells that meet preset conditions based on measurement results of each cell and access measurement thresholds of each cell in access information.

[0160] In some embodiments, the measurement threshold may be predefined.

[0161] In some embodiments, the preset condition includes at least one of the following:

[0162] The measurement result of the candidate cell is greater than or equal to the access measurement threshold of the candidate cell;

[0163] In the case where the candidate cell is a second type cell, the measurement result of the candidate cell is greater than the measurement result of the associated first type cell;

[0164] In a case where the candidate cell is a second-type cell, a difference between a measurement result of the candidate cell and a measurement result of an associated first-type cell is greater than a first threshold;

[0165] When the candidate cell is a second-type cell, the measurement result of the candidate cell is greater than the second threshold, the measurement result of the associated first-type cell is greater than the third threshold, and the second threshold is greater than or equal to the third threshold.

[0166] In some embodiments, the access measurement threshold for the first type of cell is different from the access measurement threshold for the second type of cell.

[0167] In some embodiments, the access measurement threshold of the first type of cell is less than or equal to the access measurement threshold of the second type of cell.

[0168] It is understandable that the second type cell (i.e., the non-anchor cell) is an energy-saving cell. Only when the measurement result of the second type cell is good will the first node access the second type cell and switch the second type cell to a normal cell. The access measurement threshold of the first type cell is less than or equal to the access measurement threshold of the second type cell, which can ensure that the state of the second type cell is switched only when the measurement result of the second type cell is very good, thereby avoiding frequent state switching of the second type cell.

[0169] In some embodiments, the access measurement thresholds are indicated in a list, and each access measurement threshold is associated with one or more first type cells / second type cells.

[0170] As an example, the association method may include: each row of the list includes both the access measurement threshold and the PCI of the second type cell. As another example, the association method may include: the access measurement thresholds in the list correspond to the PCIs of the cells in ascending order of index. The cells include first type cells and second type cells associated with the first type cells.

[0171] In some embodiments, the PCI of each cell in the access information is associated with an access measurement threshold.

[0172] S402: Determine a target cell from candidate cells.

[0173] In some embodiments, determining a target cell from candidate cells includes at least one of the following:

[0174] Select the cell with the best measurement result or the highest measurement value among the candidate cells as the target cell;

[0175] Select the cell with the largest difference between the measurement result and the access measurement threshold among the candidate cells as the target cell;

[0176] The first node randomly selects a cell from the candidate cells as the target cell.

[0177] In some embodiments, there is only one candidate cell, and this cell is the target cell.

[0178] In some embodiments, the above-mentioned determination of the target cell from the candidate cells can also be implemented as: determining the target cell from the candidate cells based on the received third signaling; and / or determining the target cell from the candidate cells based on at least one of the terminal identifier, cell identifier, physical cell identifier, terminal type, service type, number of access resources of the cell, and access parameters.

[0179] In some embodiments, the third signaling includes at least one of the following: an identifier of the target cell, a physical cell identifier of the target cell, an identifier list of the target cell, a physical cell identifier list of the target cell, and an indication indicating whether to access the cell. Based on the indication of the third signaling, the first node can determine the target cell that can be accessed.

[0180] In some embodiments, the third signaling is indicated by at least one of SSB, MIB, DCI (e.g., paging DCI or SI-RNTI scrambled DCI), PDSCH (e.g., paging PDSCH), PEI, LP-WUS signaling, and SIB signaling.

[0181] In some embodiments, the third signaling may be radio resource control (RRC) signaling, or may be signaling sent by a core network, or may be NAS signaling.

[0182] In some embodiments, the above-mentioned determining the target cell from the candidate cells based on at least one of the terminal identifier, cell identifier, physical cell identifier, terminal type, service type, number of access resources of the cell, and access parameters may include at least one of the following a1-a7:

[0183] a1. Determine the target cell from the candidate cells based on the terminal identifier.

[0184] As an example, when mod(terminal identifier, A) = mod(cell identifier, A), the terminal corresponding to the terminal identifier (i.e., the first node) can access the target cell corresponding to the cell identifier. A is a positive integer. In some embodiments, A is predefined or indicated by signaling. Alternatively, when mod(terminal identifier, A) = mod(physical cell identifier, A), the terminal corresponding to the terminal identifier (i.e., the first node) can access the target cell corresponding to the physical cell identifier. A is a positive integer. In some embodiments, A is predefined or indicated by signaling.

[0185] As another example, when mod(terminal identifier, A)=B, the terminal corresponding to the terminal identifier (ie, the first node) can access the second type of cell (ie, the non-anchor cell). A is a positive integer, and B is an integer greater than or equal to 0.

[0186] As another example, when mod(terminal identifier, A)=B, the terminal corresponding to the terminal identifier (ie, the first node) selects the cell with the smallest absolute difference between the cell identifier or physical cell identifier and B as the target cell.

[0187] As another example, the first node selects a mod(terminal identifier, X)+1th cell from X cells as the target cell. The X cells are sorted according to the size of the cell identifier or physical cell identifier, or the order of the measurement results.

[0188] As another example, when mod(terminal identifier, cell identifier / physical cell identifier)=B, the terminal corresponding to the terminal identifier (ie, the first node) can access the cell. B is an integer greater than or equal to 0.

[0189] a2. Determine the target cell from the candidate cells based on the access priority.

[0190] In some embodiments, the first node selects a cell with the highest access priority as the target cell.

[0191] The access priority may be indicated by the base station through signaling / signaling, or by the core network, or by the NAS, or calculated from the cell identifier or physical cell identifier. For example, the larger the physical cell identifier, the lower the access priority. In some embodiments, the access priority is obtained based on predefined information.

[0192] a3. Determine the target cell from the candidate cells based on the number of access resources in the cell.

[0193] Exemplarily, the first node selects a cell with the highest number of access resources as the target cell.

[0194] a4. Determine the target cell from the candidate cells based on the terminal type.

[0195] In some embodiments, the first node selects a cell on which it has camped or camped most recently, or selects a cell on which it camped most recently as a target cell.

[0196] a5. Determine the target cell from the candidate cells based on the access parameters.

[0197] In some embodiments, the access parameter may be an access weight of a cell.

[0198] As an example, each cell indicates an access weight and the number of access resources of the cell, and the first node selects a cell with the largest product of the access weight and the number of access resources of the cell as the target cell.

[0199] As another example, the first node may select a cell with the largest access weight as the target cell.

[0200] a6. Based on the service type, determine the target cell from the candidate cells.

[0201] Exemplarily, when the data packet corresponding to the service type is large or the delay requirement is high, the first node selects the first type of cell as the target cell.

[0202] It can be understood that at this time, the first type of cell is a normal cell, which can ensure that the first node can access quickly.

[0203] Exemplarily, when the data packet corresponding to the service type is large and has a low delay requirement, the first node may select the second type cell as the target cell.

[0204] It is understandable that at this time, no user accesses the second type cell (and non-anchor cell), and when the first node accesses, there are sufficient resources to transmit data.

[0205] a7. Based on the group identifier, determine the target cell from the candidate cells.

[0206] As an example, select the first cell from X cells. The X cells are accessed as target cells. N group is the total number of groups, and group ID is the group identifier. The X cells are sorted according to the size of the cell identifier or the order of the measurement results.

[0207] As another example, when mod(cell ID, A)=group ID, the cell corresponding to the cell ID is determined to be the target cell. A is a positive integer.

[0208] In some embodiments, a group identity is associated with a group of cells.

[0209] As an example, when the terminal identifier / group identifier is an integer, the first node may access the cell corresponding to the group identifier.

[0210] As another example, when mod(terminal identifier, A)=group identifier, the first node may access the cell corresponding to the group identifier.

[0211] In some embodiments, A is predefined or indicated by signaling. The grouping information of the cell is determined by the core network.

[0212] In some embodiments, the above-mentioned method for determining a target cell may be combined to comprehensively determine the target cell.

[0213] For example, cells are divided into multiple groups, distinguished by group identifiers. When multiple candidate cells exist within a group with the same access measurement threshold, the first node can randomly select a cell as the target cell. If each group contains at most one candidate cell, the first node selects the cell with the best measurement result as the target cell. Alternatively, the first node may further determine the target cell based on at least one of the following: a terminal identifier, a signaling indication, a cell identifier, or an access priority.

[0214] For example, there are multiple candidate cells, and the candidate cells can be obtained through signaling indication, or can be all cells accessible to the first node. The signaling can be core network signaling, NAS signaling, MIB, SIB, etc. The first node selects a cell that meets the conditions from the candidate cells based on the measurement results. If the number of cells that meet the conditions is greater than one, the target cell can be determined from the candidate cells based on at least one of the terminal identifier, cell identifier, physical cell identifier, terminal type, service type, number of access resources of the cell, and access parameters.

[0215] That is, the first node may combine and use multiple methods for determining a target cell until a target cell is determined from multiple cells.

[0216] In some embodiments, the order of using different methods for determining a target cell may be predefined or indicated by signaling.

[0217] It is understandable that the access information includes information of different dimensions of the first type cell and the second type cell, as well as information required for the first node to access. The first node determines the target cell from the candidate cells based on the access information, which can make the first node's judgment and selection of the target cell more accurate, ensure the first node's smooth access to the target cell, and ensure the stability of the first node's access and access instructions.

[0218] In some embodiments, as shown in FIG6 , the above S101 may be implemented as: S501 - S502 .

[0219] S501. Determine a candidate cell according to the received fourth signaling.

[0220] In some embodiments, the fourth signaling is indicated by at least one of SSB, MIB, DCI, PDSCH, PEI, LP-WUS signaling, and SIB signaling.

[0221] As an example, the fourth signaling includes at least one of the following: a cell identifier and a cell PCI. In this case, the fourth signaling only indicates one cell, and the first node can determine that the candidate cell is one of the cells in the fourth signaling based on the fourth signaling.

[0222] As another example, the fourth signaling includes at least one of the following: an identifier of a candidate cell, a physical cell identifier of the candidate cell, a list of identifiers of the candidate cell, a list of physical cell identifiers of the candidate cell, and an indication of whether to access the cell. In this case, the fourth signaling may indicate more than one candidate cell, meaning that the first node needs to further determine a target cell from the candidate cells.

[0223] In some embodiments, the identifier of the candidate cell identifies the cell that can be accessed. The candidate cell identifier list indicates one or more cells that can be accessed. Including first type cells and second type cells. In the candidate cell identifier list, the identifier of each cell corresponds to an index, and the fourth signaling indicates the identifier of the cell by indicating the index. Exemplarily, the indication i in the fourth signaling indicates the identifier of the i+1th cell in the list. Alternatively, the fourth signaling can also indicate the identifier of the candidate cell through X bits. Exemplarily, the number of bits indicating the candidate cell identifier in the fourth signaling is determined by the number of cells in the candidate cell identifier list. For example, if the number of cells in the candidate cell identifier list is A, then the number of bits indicating the candidate cell identifier in the fourth signaling is Each codeword corresponds to a cell identifier. For another example, if the number of cells in the candidate cell identifier list is A, then the number of bits in the fourth signaling indicating the candidate cell identifier is A. Each bit corresponds to a cell in the candidate cell identifier list. For example, '0' can be used to indicate that access to the corresponding cell is prohibited, and '1' can be used to indicate that access to the corresponding cell is permitted.

[0224] In some embodiments, the fourth signaling further includes a list of identifiers of candidate cells, and each index in the list corresponds to a list of identifiers of a group of candidate cells.

[0225] In some embodiments, the fourth signaling includes multiple blocks, each of which is used to indicate identifiers of multiple candidate cells / identifier lists of candidate cells. The identifier of each candidate cell / identifier list of each candidate cell is indicated in a block. For example, the number of bits indicating the candidate cells in the fourth signaling is determined by the number of identifiers of the candidate cells / identifier lists of candidate cells. One or more bits constitute a block. Each block in the fourth signaling indicates access information for the identifier of a candidate cell / identifier list of candidate cells.

[0226] In some embodiments, the PCI indicates a cell that can be accessed. The PCI identifier list of the candidate cell indicates one or more cells that can be accessed, and the PCI identifier list of the candidate cell includes a PCI identifier list of the first type of cell and a PCI identifier list of the second type of cell. In the PCI identifier list of the candidate cell, the PCI identifier of each cell corresponds to an index, and the fourth signaling indicates the PCI identifier of the cell by indicating the index. Exemplarily, the indication i in the fourth signaling indicates the PCI identifier of the i+1th cell in the list. Alternatively, the fourth signaling can also indicate the PCI identifier of the candidate cell through X bit. Exemplarily, the number of bits indicating the candidate cell identifier in the fourth signaling is determined by the number of cells in the PCI identifier list of the candidate cell. For example, if the number of cells in the PCI identifier list of the candidate cell is A, then the number of bits indicating the candidate cell identifier in the fourth signaling is Each codeword corresponds to a cell identifier. For another example, if the number of cells in the candidate cell PCI identifier list is A, then the number of bits in the fourth signaling indicating the candidate cell identifier is A. Each bit corresponds to a cell in the cell identifier list. For example, '0' can be used to indicate that access to the corresponding cell is prohibited, and '1' can be used to indicate that access to the corresponding cell is permitted.

[0227] In some embodiments, the fourth signaling further includes a list of PCI identifiers of candidate cells, and each index in the list corresponds to a list of PCI identifiers of a group of candidate cells.

[0228] In some embodiments, the fourth signaling includes multiple blocks, and the multiple blocks are used to indicate the PCI identifiers of multiple candidate cells / PCI identifier lists of candidate cells, and the PCI identifier of each candidate cell / PCI identifier list of each candidate cell is indicated in one block. For example, the number of bits indicating the candidate cell PCI in the fourth signaling is determined by the number of identifiers of the candidate cell PCI / PCI identifier lists of candidate cells. One or more bits constitute a block. Each block in the fourth signaling indicates access information of the PCI identifier of a candidate cell / PCI identifier list of a candidate cell.

[0229] In some embodiments, the indication for indicating whether to access a cell may indicate whether the first node can access the cell receiving the fourth signaling, or indicate whether the first node can access a first type of cell (i.e., an anchor cell). Exemplarily, the indication for indicating whether to access a cell may be indicated by one bit, with different states of the bit representing accessibility or inaccessibility. For example, 0 represents inaccessibility, and 1 represents accessibility.

[0230] In some embodiments, the above-mentioned indication for indicating whether to access a cell may also indicate whether the first node can access a second type of cell (i.e., a non-anchor cell). Exemplarily, the indication for indicating whether to access a cell may be indicated by one bit, with different states of the bit representing accessibility or inaccessibility. For example, 0 represents inaccessibility, and 1 represents accessibility. If the indication indicates that accessibility to a second type of cell is possible, the first node may select a second type of cell for access.

[0231] In some embodiments, the indication for indicating whether to access a cell may also indicate whether the first node accesses a first type cell or a second type cell. For example, the indication for indicating whether to access a cell may be indicated by a single bit, with different states of the bit representing access to different types of cells. For example, 0 represents access to a second type cell, and 1 represents access to a first type cell.

[0232] S502: Determine a target cell to be accessed from candidate cells.

[0233] In some embodiments, determining a target cell from candidate cells includes at least one of the following:

[0234] Select the cell with the best measurement result or the highest measurement value among the candidate cells as the target cell;

[0235] Select the cell with the largest difference between the measurement result and the access measurement threshold among the candidate cells as the target cell;

[0236] The first node randomly selects a cell from the candidate cells as the target cell;

[0237] The first node selects one or more cells according to the measurement result;

[0238] The first node selects one or more cells according to the access information;

[0239] The first node determines in sequence according to the order of the candidate cell identifier list, and determines a cell whose measurement result is greater than or equal to the access measurement threshold as the target cell.

[0240] Illustratively, the fourth signaling indicates a list of candidate cell identifiers, where the candidate cell identifiers are sorted in the order of recommended access. The first node first determines whether the first cell is accessible. If so, the first cell becomes the target cell. If not, the node determines whether the second cell is accessible, and so on. The access priority of the cells is related to their order in the list.

[0241] In some embodiments, the above-mentioned determination of the target cell from the candidate cells may also be implemented as follows: determining the target cell from the candidate cells based on access information; and / or determining the target cell from the candidate cells based on at least one of the first node identifier, the cell identifier, the physical cell identifier, the first node type, the service type, the number of access resources of the cell, and the access parameters. Some implementations of this embodiment and reference to the above-mentioned description of determining the target cell based on access information and based on at least one of the first node identifier, the cell identifier, the physical cell identifier, the first node type, the service type, the number of access resources of the cell, and the access parameters are not further described in detail in the embodiments of the present disclosure.

[0242] It should be noted that the target cell in the embodiment of the present disclosure can be a single target cell, which the first node can subsequently access, or a plurality of candidate cells, which the first node can subsequently determine as the cell to access from among the plurality of candidate cells.

[0243] In some embodiments, the various methods for determining target / candidate cells described in the embodiments of the present disclosure may be used in combination. For example, a measurement result (e.g., RSRP (Reference Signal Receiving Power)) is first used to determine a candidate cell, and then a second candidate cell is determined in the candidate cell based on the group identifier, and then the target cell is determined in the second candidate cell based on the signaling indication. For another example, an accessible candidate cell is determined based on the signaling indication, and then the target cell is determined in the candidate cell based on the measurement result. For another example, an accessible candidate cell is first determined based on the terminal and signaling, and then the target cell is determined based on the measurement result.

[0244] In some embodiments, determining the target cell according to the signaling is the first step in determining the target cell. In some embodiments, determining the target cell according to the measurement result is the operation of finally determining a target cell.

[0245] In some embodiments, the priority of the target / candidate cell determined based on the signaling indication is greater than the priority of the target cell determined based on the access information and at least one of the first node identifier, the cell identifier, the physical cell identifier, the first node type, the service type, the number of access resources of the cell, and the access parameters. In other words, when a signaling indication is received indicating that the target / candidate cell is accessible, the target / candidate cell determined based on the access information and at least one of the first node identifier, the cell identifier, the physical cell identifier, the first node type, the service type, the number of access resources of the cell, and the access parameters and not within the scope of the signaling indication is not considered.

[0246] In some embodiments, the target / candidate cell determined according to the measurement results has the highest priority, that is, the target cell determined by multiple methods must be the target / candidate cell determined according to the measurement results.

[0247] In some embodiments, there is no order in which target / candidate cells are determined using multiple methods, and the target cell finally determined is the intersection of the target / candidate cells determined using multiple methods. Alternatively, the target cell finally determined is the intersection of the target / candidate cells determined using multiple methods.

[0248] In some embodiments, the method further includes: receiving fourth signaling on the first type cell or a second type cell associated with the first type cell. The fourth signaling is access information signaling or core network signaling. In some embodiments, the fourth signaling is NAS signaling.

[0249] In some embodiments, when the fourth signaling is signaling received on the second type of cell, the fourth signaling is LP WUS signaling. When the fourth signaling is signaling accessed on the first type of cell, the fourth signaling is indicated by at least one of the following: SSB, MIB, DCI, paging, PDSCH, PEI, LP-WUS, SI-RNTI scrambled DCI, or SIB1.

[0250] Exemplarily, the SIB1 indicating the fourth signaling may be the SIB1 of the first type of cell or the SIB1 of the second type of cell.

[0251] Exemplarily, the first node receives SIB1s of the first type cell and the second type cell on the first type cell, and only the SIB1 of the first type cell includes the fourth signaling.

[0252] Exemplarily, the first node receives SIB1s of the first type cell and the second type cell on the first type cell, and the SIB1 of each cell indicates whether to access the cell.

[0253] Exemplarily, the first node receives SIB1 of the first type cell and the second type cell on the first type cell, and the SIB1 of each cell includes fourth signaling, and the content of the signaling is the same.

[0254] Exemplarily, the first node receives the SIB1 of the first type of cell on the first type of cell, and only the SIB1 of the first type of cell includes the fourth signaling.

[0255] In some embodiments, LP WUS signaling may be received on a first type cell and also on a second type cell.

[0256] In some embodiments, when the LP WUS signaling indicates whether a certain cell (ie, the cell receiving the LP WUS signaling) is accessible, the LP WUS signaling may be received on a first type of cell or a second type of cell.

[0257] In some embodiments, when the LP WUS signaling indicates information such as a cell ID, a PCI, a PCI list, or a cell ID list, the LP WUS signaling is received on a first type of cell.

[0258] It is understandable that the second type cell is a non-anchor cell and cannot send SIB information, that is, the first node cannot receive information such as SIB, paging DCI, and PEI on the second type cell.

[0259] It is understandable that in addition to determining the target cell based on the access information, the first node can also accurately determine the target cell through the received signaling, thereby avoiding unnecessary retries and access processes for the first node, reducing network load, and improving resource utilization efficiency.

[0260] In some embodiments, as shown in FIG7 , the above S101 may be implemented as: S601 - S602 .

[0261] S601. Determine a candidate cell according to at least one of a terminal identifier, a cell identifier, a physical cell identifier, a terminal type, a service type, a number of access resources of the cell, and an access parameter.

[0262] In some embodiments, the implementation of the above S601 can refer to the above description of the terminal identifier, cell identifier, physical cell identifier, terminal type, service type, number of access resources of the cell, and access parameters, which will not be repeated in the embodiments of the present disclosure.

[0263] S602: Determine a target cell to be accessed from candidate cells.

[0264] In some embodiments, the above S602 may be implemented as: determining the target cell from the candidate cells according to the access information; and / or determining the target cell from the candidate cells according to the received fifth signaling.

[0265] In some embodiments, the implementation of determining the target cell from the candidate cells based on the access information may refer to the above description of the access information, which will not be repeated in the embodiments of the present disclosure.

[0266] In some embodiments, the fifth signaling includes at least one of the following: an identifier of the target cell, a physical cell identifier of the target cell, and an indication for indicating whether to access the cell.

[0267] In some embodiments, the fifth signaling is indicated by at least one of SSB, MIB, DCI, PDSCH, PEI, LP-WUS signaling, and SIB signaling.

[0268] In some embodiments, the content of the fifth signaling can refer to the description of the fourth signaling mentioned above, and will not be repeated here in the embodiments of the present disclosure.

[0269] It can be understood that the method provided in the embodiment of the present disclosure determines the candidate cell and the target cell based on at least one of the terminal identifier, cell identifier, physical cell identifier, terminal type, service type, number of access resources of the cell, and access parameters. The target cell can be determined through multiple aspects of information, avoiding inaccurate access and access failure caused by a single piece of information, and ensuring normal access of the terminal.

[0270] Referring to Figure 8 , which is a flow chart of a cell access method provided by an embodiment of the present disclosure, as shown in Figure 8 , the cell access method provided by an embodiment of the present disclosure is applied to a second node and includes the following S701 .

[0271] S701. Send access information to a first node on a first type of cell.

[0272] The access information includes configuration information of access resources of a second type cell associated with the first type cell, and the second type cell associated with the first type cell includes a target cell.

[0273] In some embodiments, the implementation of S701 may refer to the description of S101 above, and the embodiments of the present disclosure will not be repeated here.

[0274] In some embodiments, the access information further includes at least one of the following:

[0275] Configuration information of access resources of the first type of cell;

[0276] an indication of a second type of cell associated with the first type of cell;

[0277] an indication of cells to which access is permitted;

[0278] Indication of cells to which access is denied;

[0279] Access parameters.

[0280] In some embodiments, the access parameter includes at least one of the following: access weight, access priority, access selection mode, terminal identification, and terminal group identification.

[0281] It can be understood that based on the cell access method provided by the embodiment of the present disclosure, the second node sends access information on the first type of cell, and the access information includes the configuration information of the access resources of the second type of cell, and the second type of cell includes the target cell. This allows the first node to determine the target cell to be accessed without having to wait for the target cell to send a public signal / signaling (for example, SIB information) before accessing. Instead, it can directly access the target cell based on the configuration information of the access resources of the target cell. This avoids the problem of access failure caused by the first node waiting for the public signal / signaling, ensures the normal access of the first node, and reduces the risk of access failure of the first node.

[0282] In some embodiments, as shown in FIG9 , the above method further includes: S801 - S802 .

[0283] S801. Send access information to a first node on a first type of cell.

[0284] The access information includes configuration information of system information of a second type of cell associated with the first type of cell, where the second type of cell includes a target cell;

[0285] S802: Send system information of the target cell to the first node in the target cell.

[0286] The system information of the target cell includes configuration information of access resources of the target cell.

[0287] In some embodiments, the implementation of the above S801-S802 can refer to the description of the above S201-S202, and the embodiments of the present disclosure will not be repeated here.

[0288] In some embodiments, the access information further includes at least one of the following:

[0289] Reference signal configuration of the second type cell;

[0290] Synchronization signal block configuration of the second type of cell;

[0291] downlink carrier position of the second type cell;

[0292] downlink frequency of the second type of cell;

[0293] frequency and / or carrier position of the uplink wake-up signal of the second type cell;

[0294] Access parameters.

[0295] In some embodiments, as shown in FIG10 , the above method further includes: S901 - S902 .

[0296] S901: Receive first signaling sent by a first node in a target cell or a first type cell associated with the target cell.

[0297] The first signaling is used to request configuration information of access resources of the target cell;

[0298] S902: In response to the first signaling, send a second signaling to the first node.

[0299] The second signaling includes configuration information of access resources of the target cell.

[0300] In some embodiments, the implementation of the above S901-S902 can refer to the description of the above S301-S302, and the embodiments of the present disclosure will not be repeated here.

[0301] In some embodiments, the first signaling is uplink wake-up signaling.

[0302] It is understandable that when the access information on the first type of cell does not include the configuration information of the access resources of the target cell, the second node can receive the first signaling sent by the first node and send the second signaling to the first node, so that the first node can normally access the target cell and use the network service based on the configuration information of the access resources of the target cell. Alternatively, when the second type of cell is not associated with the first type of cell, the second node can promptly receive the first signaling sent by the first node and send the second signaling to the first node to request the configuration information of the access resources of the target cell, so that the first node can normally access the target cell and use the network service based on the configuration information of the access resources of the target cell. In some embodiments, the second type of cell not being associated with the first type of cell indicates a second type of cell, and the second type of cell is an independent cell, and the relevant information of the cell is not transmitted on other cells.

[0303] In some embodiments, the configuration of the first signaling is indicated in the SSB of the second type of cell.

[0304] In some embodiments, the method further includes: sending access information to the first node. The access information includes: transmission resource configuration of the first signaling and / or transmission resource configuration of the second signaling.

[0310] Access measurement threshold;

[0311] downlink carrier position of the second type cell;

[0312] Configuration information of system information of the second type of cell.

[0313] It is understandable that the access information includes information of different dimensions of the first type cell and the second type cell, as well as information required for the first node to access. The first node determines the target cell from the candidate cells based on the access information, which can make the first node's judgment and selection of the target cell more accurate, ensure the first node's smooth access to the target cell, and ensure the stability of the first node's access and access instructions.
