[0002] The three major application scenarios of 5th Generation Mobile Communication Technology (5G) include enhanced mobile broadband (eMBB), massive machine-type communications (mMTC), and ultra-reliable low-latency communications (uRLLC).

[0042] The following will describe the technical solutions in the embodiments of this application in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0043] FIG1 is a schematic diagram of an application scenario of an embodiment of the present application.

[0044] As shown in Figure 1, a communication system 100 may include a terminal device 110 and a network device 120. The network device 120 may communicate with the terminal device 110 via an air interface. The terminal device 110 and the network device 120 support multi-service transmission.

[0045] It should be understood that the embodiments of the present application are only illustrative of the communication system 100, but the embodiments of the present application are not limited thereto. That is, the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Internet of Things (IoT) system, Narrow Band Internet of Things (NB-IoT) system, enhanced Machine-Type Communications (eMTC) system, 5G communication system (also known as New Radio (NR) communication system), or future communication systems.

[0046] In the communication system 100 shown in Figure 1, the network device 120 may be an access network device that communicates with the terminal device 110. The access network device may provide communication coverage for a specific geographical area and may communicate with the terminal device 110 (eg, UE) located within the coverage area.

[0047] The network device 120 may be an evolved Node B (eNB or eNodeB) in a Long Term Evolution (LTE) system, or a Next Generation Radio Access Network (NG RAN) device, or a base station (gNB) in an NR system, or a wireless controller in a Cloud Radio Access Network (CRAN), or the network device 120 may be a relay station, an access point, an in-vehicle device, a wearable device, a hub, a switch, a bridge, a router, or a network device in a future evolved Public Land Mobile Network (PLMN), etc.

[0048] The terminal device 110 may be any terminal device, including but not limited to a terminal device connected to the network device 120 or other terminal devices by wire or wireless connection.

[0049] For example, the terminal device 110 may refer to an access terminal, user equipment (UE), a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user apparatus. An access terminal may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, an IoT device, a satellite handheld terminal, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a 5G network, or a terminal device in a future evolution network, etc.

[0050] The terminal device 110 can be used for device-to-device (D2D) communication.

[0051] The wireless communication system 100 may further include a core network device 130 that communicates with the network device 120. The core network device 130 may be a 5G core network (5G Core, 5GC) device, such as an Access and Mobility Management Function (AMF), an Authentication Server Function (AUSF), a User Plane Function (UPF), or a Session Management Function (SMF). Optionally, the core network device 130 may also be an Evolved Packet Core (EPC) device of an LTE network, such as a Session Management Function + Core Packet Gateway (SMF+PGW-C) device. It should be understood that SMF+PGW-C can simultaneously implement the functions that can be implemented by SMF and PGW-C. During the network evolution process, the above-mentioned core network device may also be called other names, or a new network entity may be formed by dividing the functions of the core network, which is not limited in the embodiments of the present application.

[0052] The functional units in the communication system 100 may also establish connections and implement communication via next generation (NG) network interfaces.

[0053] For example, the terminal device establishes an air interface connection with the access network device through the NR interface for transmitting user plane data and control plane signaling; the terminal device can establish a control plane signaling connection with the AMF through the NG interface 1 (referred to as N1); the access network device, such as the next generation wireless access base station (gNB), can establish a user plane data connection with the UPF through the NG interface 3 (referred to as N3); the access network device can establish a control plane signaling connection with the AMF through the NG interface 2 (referred to as N2); the UPF can establish a control plane signaling connection with the SMF through the NG interface 4 (referred to as N4); the UPF can exchange user plane data with the data network through the NG interface 6 (referred to as N6); the AMF can establish a control plane signaling connection with the SMF through the NG interface 11 (referred to as N11); the SMF can establish a control plane signaling connection with the PCF through the NG interface 7 (referred to as N7).

[0054] Figure 1 exemplarily shows a network device, a core network device and two terminal devices. Optionally, the wireless communication system 100 may include multiple network devices and each network device may include other numbers of terminal devices within its coverage area, which is not limited in this embodiment of the present application.

[0055] It should be noted that Figure 1 is merely an example of a system applicable to this application. Of course, the methods described in the embodiments of this application can also be applied to other systems. Furthermore, the terms "system" and "network" are often used interchangeably herein. The term "and / or" herein simply describes an association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the associated objects are in an "or" relationship. It should also be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association relationship. For example, "A indicates B" can mean that A directly indicates B, for example, B can obtain information through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can obtain information through C; or it can mean that A and B have an association relationship. It should also be understood that the "correspondence" mentioned in the embodiments of this application can mean that there is a direct or indirect correspondence between two objects, or that there is an association relationship between the two objects, or a relationship between an indicator and the indicated, a configuration and the configured, and so on. It should also be understood that the “predefined” or “predefined rules” mentioned in the embodiments of the present application can be implemented by pre-saving corresponding codes, tables or other methods that can be used to indicate relevant information in devices (for example, including terminal devices and network devices), and the present application does not limit its specific implementation method. For example, predefined can refer to what is defined in the protocol. It should also be understood that in the embodiments of the present application, the “protocol” may refer to a standard protocol in the field of communications, such as LTE protocols, NR protocols, and related protocols used in future communication systems, and the present application does not limit this.

[0056] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0057] 3GPP R17 introduced RedCap UE for NR systems. Currently, RedCap UE mainly has three scenarios.

[0058] 1. Industrial Wireless Sensors. Compared to URLLC, industrial wireless sensors have relatively low latency and reliability requirements, and also have lower cost and power consumption requirements. Key requirements and features for industrial wireless sensors include: 99.99% communication reliability, end-to-end latency <100ms, a reference data rate less than 2Mbps with uplink services as the primary focus, stationary devices, and battery life of several years. Furthermore, for safety-related wireless sensors, latency requirements are even lower, for example, 5-10ms.

[0059] 2. Video surveillance. Video surveillance is primarily used in smart cities and industrial plants. Data collection and processing in smart cities facilitates more effective monitoring and control of urban resources, providing more effective services to city residents. Video surveillance primarily serves as an uplink service. Other key requirements include: a reference rate of 2 to 4 Mbps for standard resolution video, latency less than 500 ms, and communication reliability of 99% to 99.9%. High-definition video requires a rate of 7.5 to 25 Mbps.

[0060] 3. Wearables: These devices include smartwatches, smart bracelets, electronic health devices, and some medical monitoring equipment. A common characteristic of these devices is their small size. Key requirements for wearables include downlink and uplink reference rates of 5-50 Mbps and 2-5 Mbps, respectively; downlink and uplink peak rates of 150 Mbps and 50 Mbps, respectively; and battery life of several days or even one to two weeks.

[0061] To enable RedCap UEs and standard terminals (i.e., non-RedCap UEs) to share the same synchronization signal block (SSB), control resource set, and system information block (SIB), the maximum bandwidth of RedCap UEs in the low-frequency band (i.e., FR1 band) can be reduced from 100MHz to 20MHz. At the same time, the maximum bandwidth of RedCap UEs in the high-frequency band (i.e., FR2 band) can be reduced to 100MHz. The maximum bandwidth here includes the radio frequency (RF) bandwidth and the baseband bandwidth.

[0062] The following introduces the cell access control mechanism.

[0063] In the NR system, the network equipment can carry cell access barring information (cellBarred) in the Master Information Block (MIB). CellBarred can be used to indicate whether all terminals are prohibited from accessing the current cell. If cellBarred indicates prohibition (i.e., barred), the terminal device needs to reselect the cell; if cellBarred indicates not prohibition (i.e., not barred), the terminal device can access the current cell. The MIB can also carry intraFreqReselection indication information. IntraFreqReselection can indicate whether all UEs are allowed to perform cell reselection among neighboring cells of the same frequency.

[0064] In addition, for RedCap UE, R17 introduces cell barring access information (cellBarredRedCap1Rx) for RedCap UE supporting one receive link (RX), cell barring access information (cellBarredRedCap2Rx) for RedCap UE supporting two RXs, and cell barring access information (halfDuplexRedCapAllowed) for RedCap UE supporting half-duplex.

[0065] 3GPP R18 introduces a new RedCap UE type with lower complexity and lower cost for RedCap UEs supporting the FR1 frequency band. Specifically, the bandwidth supported by the newly introduced RedCap UE with lower complexity and lower cost may be smaller than the maximum bandwidth supported by the current RedCap UE. For example, the maximum bandwidth supported by the newly introduced RedCap UE type may be 5 MHz.

[0066] Understandably, with the introduction of the less complex and lower-cost RedCap UE type, there is currently no clear method for how the network can perform access control on the new RedCap UE and achieve more refined terminal access control.

[0067] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0068] Referring to FIG2 , the communication processing method provided in the embodiment of the present application may include the following steps:

[0069] Step 210: The network device sends first information, and the terminal device receives the first information, where the first information is related to cell access of a low-capability terminal; wherein the low-capability terminal refers to a terminal whose maximum supported bandwidth is less than 20 MHz.

[0070] The low-capability terminal mentioned in the embodiments of the present application may be a RedCap UE that is less complex and / or less expensive than the RedCap UE introduced in R17.

[0071] In R17, the maximum bandwidth supported by RedCap UE in FR1 band is 20 MHz, and the maximum bandwidth supported by RedCap UE in FR2 band is 100 MHz. The low-capability terminal mentioned in the embodiment of the present application may be a RedCap UE that supports a maximum bandwidth less than 20 MHz.

[0072] For example, the maximum bandwidth supported by the above-mentioned low-capability terminal is 5 MHz, or the maximum baseband bandwidth supported by the above-mentioned low-capability terminal is 5 MHz, and the RF bandwidth remains unchanged, or the maximum bandwidth supported by the above-mentioned low-capability terminal only in the physical shared channel (which may include the physical uplink / downlink shared channel, i.e., PUSCH / PDSCH) is 5 MHz.

[0073] It should be noted that the maximum bandwidth supported by the above low-capability terminal may be for the FR1 frequency band. In the embodiment of the present application, the low-capability terminal may also be referred to as an enhanced low-capability terminal (Enhanced RedCap UE, eRedCap UE).

[0074] Optionally, the network device may broadcast the first information within its communication coverage area. In other words, the first information may be broadcast information.

[0075] Optionally, the first information may be a system information block (SIB). For example, the first information may be at least one of SIB1-SIB14. The embodiment of the present application does not limit the specific SIB type.

[0076] It is understandable that the network device can configure the first information related to cell access that is unique to this type of low-capability terminal for the eRedCap UE and broadcast the first information to the terminal device. Accordingly, after receiving the first information, the terminal device can access the cell according to the first information.

[0077] As can be seen, by configuring eRedCap UE-specific cell access information, eRedCap UEs can be individually controlled for cell access, thus achieving more flexible and refined cell access. For example, when network congestion occurs, the network may still expect some terminals to be able to access the network. In this case, the network can broadcast the first eRedCap UE-specific information to only allow eRedCap UEs with a maximum bandwidth less than 20 MHz to access the network, thus achieving more refined access control.

[0078] Optionally, the first information may indicate at least one of the following:

[0079] Whether the eRedCap UE is prohibited from accessing the first cell;

[0080] Whether the eRedCap UE is allowed to perform intra-frequency cell reselection;

[0081] At least one second information, the at least one second information corresponds to at least one frequency point, and each second information is used to indicate whether the eRedCap UE is allowed to access the frequency point corresponding to the current second information.

[0082] In an embodiment of the present application, the first information may include a cell access indication parameter (cellBarred) configured separately for the eRedCap UE, such as the parameter "cellBarredRedCapEnhanced". This parameter indicates whether the eRedCap UE is prohibited from accessing the first cell, that is, whether the first cell supports the eRedCap UE. Here, the first cell may be the cell corresponding to the network device that sends the system information, and may be a serving cell or a target cell to be accessed.

[0083] In the embodiment of the present application, the first information may include an intra frequency reselection indication (IFRI) parameter configured specifically for the eRedCap UE. For example, the first information may include the parameter "intraFreqReselectionRedCapEnhanced". The first information indicates whether the eRedCap UE is allowed to perform intra-frequency cell reselection through this parameter.

[0084] It should be noted that if the network device does not configure the target parameter in the first information, the eRedCap UE may consider that the first cell is prohibited from access. The target parameter may be a parameter used to indicate whether the eRedCap UE is allowed to perform intra-frequency cell reselection, such as the parameter "intraFreqReselectionRedCapEnhanced".

[0085] In an embodiment of the present application, the first information may include at least one second information. The at least one second information may also be understood as configuration information for the eRedCap UE. Simply put, the second information may be information about whether the neighboring cell frequency (i.e., the inter-frequency frequency) supports the eRedCap UE. It should be understood that the neighboring cell frequency may include one or more, and each frequency may be configured with a second information. Each second information may indicate whether the eRedCap UE is allowed to access the frequency corresponding to the current second information.

[0086] Optionally, the second information may be represented by “redCapAccessAllowedEnhanced”.

[0087] Exemplarily, the network device may configure a list of inter-frequency points. At the same time, the network device may configure a parameter "redCapAccessAllowedEnhanced" for each frequency point in the list, and use the parameter to indicate whether the current frequency point supports eRedCap UE.

[0088] It should be noted that the first information can indicate any one of the above three items separately.

[0089] Optionally, the parameter in the first information used to indicate whether the eRedCap UE is prohibited from accessing the first cell, the parameter used to indicate whether the eRedCap UE is allowed to perform intra-frequency cell reselection, and the at least one second information mentioned above can be carried by the same SIB or by different SIBs. Exemplarily, the parameter used to indicate whether the eRedCap UE is prohibited from accessing the first cell, and the parameter used to indicate whether the eRedCap UE is allowed to perform intra-frequency cell reselection can be carried by SIB1 or other SIBs, and at least one second information can be carried by SIB4 or other SIBs, and the embodiments of the present application are not limited to this.

[0090] It can be seen that by configuring the eRedCap UE's unique access prohibition information, same-frequency reselection indication information, and information related to inter-frequency access, different access processes of the eRedCap UE can be controlled separately, thus further improving the flexibility of cell access control.

[0091] Optionally, in some embodiments, the first information may include multiple first sub-information, and the first sub-information is related to the number of receive links (RX) supported by the terminal.

[0092] Each first sub-information is used to indicate whether a terminal supporting N receiving links in the eRedCap UE is prohibited from accessing the first cell; N is greater than or equal to 1, and different first sub-information corresponds to different numbers N of receiving links.

[0093] It is understandable that eRedCap UEs can be further differentiated according to the number of receive links supported by the terminal. Different first sub-information is used to respectively indicate whether UEs with different numbers of receive links in the eRedCap UEs are prohibited from accessing the first cell. In other words, different first sub-information is used to indicate whether the first cell supports eRedCap UEs with different numbers of RX links.

[0094] Optionally, the first information can distinguish between 1 RX and 2 RXs. Specifically, "cellBarredRedCap1RxEnhanced" can be used to indicate whether an eRedCap UE supporting 1 RX is prohibited from accessing the first cell. In addition, "cellBarredRedCap2RxEnhanced" can be used to indicate whether an eRedCap UE supporting 2 RXs is prohibited from accessing the first cell. It should be noted that the first information can also distinguish eRedCap UEs with more receive links, which are not enumerated one by one in the embodiment of the present application.

[0095] For example, if "cellBarredRedCap1RxEnhanced" indicates "barred", it can be considered that the current first cell does not support all eRedCap UEs with 1 RX, and all eRedCap UEs with 1 RX are prohibited from accessing. If "cellBarredRedCap1RxEnhanced" indicates "not barred", it can be considered that the current first cell supports all eRedCap UEs with 1 RX, that is, all eRedCap UEs with 1 RX are allowed to access.

[0096] Optionally, in some other embodiments, the first information may include second sub-information and / or third sub-information, and the second sub-information and / or third sub-information may be related to the duplex capability supported by the terminal device.

[0097] The second sub-information may be used to indicate whether a terminal supporting half-duplex in the eRedCap UE is prohibited from accessing the first cell, and the third sub-information is used to indicate whether a terminal supporting full-duplex in the eRedCap UE is prohibited from accessing the first cell.

[0098] In other words, eRedCap UEs can be further differentiated according to the duplex capabilities supported by the terminal devices. An eRedCap UE supporting half-duplex can indicate whether it is prohibited from accessing the first cell through the second sub-information, while an eRedCap UE supporting full-duplex can indicate whether it is prohibited from accessing the first cell through the third sub-information.

[0099] It can be seen that in the communication processing method provided in the embodiment of the present application, cell access prohibition information can be separately configured for eRedCap UEs with different capabilities, so as to facilitate cell access control for some terminals in the eRedCap UEs. In this way, the granularity of cell access control is further reduced and the flexibility of cell access control is improved.

[0100] The following describes in detail the specific method in which the eRedCap UE determines whether it is prohibited from accessing the first cell.

[0101] In an embodiment of the present application, the eRedCap UE may independently determine whether it is prohibited from accessing the first cell based on the first information. Optionally, after receiving the first information, the eRedCap UE may perform at least one of the following:

[0102] determining, based on the first information, whether access to the first cell is prohibited;

[0103] Determining whether access to the first cell is prohibited according to the number of receiving links supported by the eRedCap UE and the plurality of first sub-information;

[0104] Whether access to the first cell is prohibited is determined according to the second sub-information and / or the third sub-information and the duplex capability supported by the eRedCap UE.

[0105] In a possible implementation, when the first information is used as separate indication information, the eRedCap UE may directly determine whether the eRedCap UE is prohibited from accessing the first cell according to the indication content of the first information.

[0106] In this implementation, referring to the flowchart shown in FIG3A , the eRedCap UE may determine whether it is barred from accessing the first cell in the following manner:

[0107] The first step is to read the first information.

[0108] Step 2: Determine whether access to the first cell is prohibited based on the first information

[0109] The eRedCap UE determines whether it is prohibited from accessing the first cell according to the first information, which can be achieved in the following manner:

[0110] determining whether the first information indicates that the eRedCap UE is prohibited from accessing the first cell;

[0111] If the first information indicates that the eRedCap UE is prohibited from accessing the first cell, the eRedCap UE considers that the first cell is currently prohibited from access; if the first information indicates that the eRedCap UE is not prohibited from accessing the first cell, the eRedCap UE considers that the first cell is currently allowed to access.

[0112] It should be understood that the first information can indicate "barred" or "notbarred." After receiving the SIB, the eRedCap UE can read the first information "cellBarredRedCapEnhanced" in the SIB. When the first information indicates "barred," it can be considered that the first cell prohibits all eRedCap UEs from accessing. When the first information indicates "notbarred," it can be considered that the first cell allows all eRedCap UEs to access.

[0113] In another possible implementation, when the first information includes multiple first sub-information, the eRedCap UE may determine whether it is prohibited from accessing the first cell according to the number of receiving links supported by it and the multiple first sub-information.

[0114] In this implementation, referring to the flowchart shown in FIG3B , the eRedCap UE may determine whether it is prohibited from accessing the first cell in the following manner:

[0115] The first step is to read multiple first sub-information;

[0116] Step 2: Determine whether access to the first cell is prohibited based on the number of supported receiving links and the plurality of first sub-information.

[0117] The eRedCap UE determines whether it is prohibited from accessing the first cell according to the number of supported receiving links and the plurality of first sub-information, which can be achieved in the following manner:

[0118] Determine the target first sub-information, where the number N of receiving links corresponding to the target first sub-information is the same as the number of receiving links supported by the eRedCap UE;

[0119] If the target first sub-information indicates that the eRedCap UE is prohibited from accessing the first cell, determining to prohibit access to the first cell;

[0120] If the target first sub-information indicates that the eRedCap UE is not prohibited from accessing the first cell, it is determined that the UE is allowed to access the first cell.

[0121] It is understandable that the eRedCap UE can first obtain the first sub-information that matches the number of RXs it supports from multiple first sub-information to obtain the target first sub-information. Then, the eRedCap UE can determine whether it is allowed to access the first cell based on the specific indication content of the target first sub-information, that is, determine whether the first cell supports the eRedCap UE with the specified number of RXs. Specifically, if the target first sub-information indicates "barred", the eRedCap UE can consider that access to the first cell is prohibited; if the target first sub-information indicates "not barred", the eRedCap UE can consider that access to the first cell is allowed.

[0122] For example, in a scenario where the network device uses "cellBarredRedCap1RxEnhanced" to indicate whether the eRedCap UE supporting 1 RX is prohibited from accessing the first cell, and uses "cellBarredRedCap2RxEnhanced" to indicate whether the eRedCap UE supporting 2 RXs is prohibited from accessing the first cell, after the eRedCap UE receives SIB1, it can read "cellBarredRedCap1RxEnhanced" or "cellBarredRedCap2RxEnhanced" in SIB1 according to the number of RXs it supports.

[0123] If the eRedCap UE supports one RX, the eRedCap UE can read "cellBarredRedCap1RxEnhanced" in SIB1. When "cellBarredRedCap1RxEnhanced" indicates "barrred", the eRedCap UE can consider that the current first cell is access-prohibited. When "cellBarredRedCap1RxEnhanced" indicates "not barrred", the eRedCap UE can consider that the current first cell is access-allowed. Correspondingly, if the eRedCap UE supports two RXs, the eRedCap UE can read "cellBarredRedCap2RxEnhanced" in SIB1. When "cellBarredRedCap2RxEnhanced" indicates "barrred", the eRedCap UE can consider that the current first cell is access-prohibited. When "cellBarredRedCap2RxEnhanced" indicates "not barrred", the eRedCap UE can consider that the current first cell is access-allowed.

[0124] In another possible implementation, when the first information includes the second sub-information and / or the third sub-information, the eRedCap UE may determine whether it is prohibited from accessing the first cell based on the second sub-information and / or the third sub-information and the duplex capability supported by the eRedCap UE.

[0125] In this implementation, referring to the flowchart shown in FIG3C , the eRedCap UE may determine whether it is barred from accessing the first cell in the following manner:

[0126] The first step is to read the second sub-information and / or the third sub-information.

[0127] In the second step, it is determined whether the UE is prohibited from accessing the first cell according to the second sub-information and / or the third sub-information and the duplex capability supported by the eRedCap UE.

[0128] The eRedCap UE determines whether it is prohibited from accessing the first cell based on the second sub-information and / or the third sub-information and the duplex capability supported by the eRedCap UE, which can be achieved in the following manner:

[0129] Determining the second sub-information or the third sub-information that matches the duplex capability supported by the eRedCap UE;

[0130] If the matched second sub-information or third sub-information indicates that the eRedCap UE is prohibited from accessing the first cell, determining to prohibit access to the first cell;

[0131] If the matched second sub-information or the third sub-information indicates that the eRedCap UE is not prohibited from accessing the first cell, it is determined that access to the first cell is allowed.

[0132] That is, the eRedCap UE may first obtain the sub-information that matches its supported duplex capability from the second sub-information and / or the third sub-information. Then, the eRedCap UE may determine whether it is allowed to access the first cell based on the specific indication content of the matching sub-information (the second sub-information or the third sub-information). Specifically, if the matching sub-information indicates "barred," the eRedCap UE may consider that access to the first cell is prohibited; if the matching sub-information indicates "not barred," the eRedCap UE may consider that access to the first cell is permitted.

[0133] Exemplarily, when the eRedCap UE is a half-duplex terminal, the eRedCap UE may select the second sub-information for cell access control. If the second sub-information indicates "barred", the eRedCap UE may consider that the first cell prohibits access by eRedCap UEs with half-duplex capabilities, that is, the first cell does not support eRedCap UEs with half-duplex capabilities. If the second sub-information indicates "not barred", the eRedCap UE may consider that the first cell allows access by eRedCap UEs with half-duplex capabilities, that is, the first cell supports eRedCap UEs with half-duplex capabilities. When the eRedCap UE is a full-duplex terminal, the eRedCap UE may select the third sub-information for cell access control. If the third sub-information indicates "barred", the eRedCap UE may consider that the first cell prohibits access by eRedCap UEs with full-duplex capabilities, that is, the first cell does not support eRedCap UEs with full-duplex capabilities. If the third sub-information indicates "not barred", the eRedCap UE may consider that the first cell allows access by eRedCap UEs with full-duplex capability, that is, the first cell supports eRedCap UEs with full-duplex capability.

[0134] In summary, in the communication processing method provided in the embodiments of the present application, the first information configured for the eRedCap UE and the sub-information included in the first information can operate independently. In other words, the eRedCap UE can directly determine whether it is prohibited from accessing the first cell based on the first information or the sub-information included in the first information, providing a simple and flexible indication method.

[0135] In another embodiment of the present application, the eRedCap UE may determine whether it is barred from accessing the first cell in combination with the cell barred information (ie, cellbarred) and the first information.

[0136] Optionally, the communication processing method provided in the embodiment of the present application may further include the following steps:

[0137] The network device sends the cell access prohibition information, and the terminal device receives the cell access prohibition information.

[0138] The cell access prohibition information may be used together with the first information to indicate whether the eRedCap UE is prohibited from accessing the first cell;

[0139] Alternatively, the cell access prohibition information is used together with the plurality of first sub-information to indicate whether the eRedCap UE is prohibited from accessing the first cell;

[0140] Alternatively, the cell access prohibition information is used together with the second sub-information and / or the third sub-information to indicate whether the eRedCap UE is prohibited from accessing the first cell.

[0141] Optionally, the cell access prohibition information may be carried in a Master Information Block (MIB).

[0142] It should be understood that the MIB generally carries general information of terminal devices. The cell access prohibition information carried in the MIB can be understood as being for all terminal devices in the network.

[0143] In a possible implementation, when the first information is used as separate indication information, the cell access prohibition information and the first information may jointly indicate whether the eRedCap UE is prohibited from accessing the first cell.

[0144] In this implementation, referring to the flowchart shown in FIG4A , the eRedCap UE may determine whether it is barred from accessing the first cell in the following manner:

[0145] In the first step, the eRedCap UE reads the cell access prohibition information.

[0146] In the second step, the eRedCap UE determines whether the cell access barring information indicates "barred".

[0147] In the third step, if the cell access barring information indicates that access to the first cell is barred (ie, indicates "barred"), the eRedCap UE determines that the first cell is currently barred.

[0148] In the fourth step, if the cell barring information indicates that the UE is not barred from accessing the first cell (ie, indicates "not barred"), the eRedCap UE obtains first information to determine whether the eRedCap UE is barred from accessing the first cell according to the first information in the SIB.

[0149] In the fifth step, the eRedCap UE determines whether the eRedCap UE is prohibited from accessing the first cell according to the first information.

[0150] Optionally, the eRedCap UE determines, according to the first information, whether the eRedCap UE is prohibited from accessing the first cell, which may be achieved in the following manner:

[0151] If the first information indicates "barred", the eRedCap UE may determine that the first cell is currently barred from access. If the first information indicates "notbarred", the eRedCap UE may determine that the first cell is currently allowed to access.

[0152] In another possible implementation, when the first information includes multiple first sub-information, the cell access prohibition information and the multiple first sub-information may jointly indicate whether the eRedCap UE is prohibited from accessing the first cell.

[0153] In this implementation, referring to the flowchart shown in FIG4B , the eRedCap UE may determine whether it is barred from accessing the first cell in the following manner:

[0154] In the first step, the eRedCap UE reads the cell access prohibition information.

[0155] In the second step, the eRedCap UE determines whether the cell access barring information indicates "barred".

[0156] In a third step, if the cell access barring information indicates that the UE is barred from accessing the first cell (ie, indicates "barred"), the eRedCap UE determines to bar the UE from accessing the first cell.

[0157] In the fourth step, if the cell barring information indicates that the UE is not barred from accessing the first cell (ie, indicates "not barred"), the eRedCap UE obtains multiple first sub-information to determine whether the eRedCap UE is barred from accessing the first cell according to the multiple first sub-information.

[0158] In the fifth step, the eRedCap UE may determine whether it is prohibited from accessing the first cell according to the number of supported receiving links and the plurality of first sub-information.

[0159] Optionally, the eRedCap UE may determine whether it is prohibited from accessing the first cell based on the number of supported receiving links and the plurality of first sub-information, which may be achieved in the following manner:

[0160] Determine the target first sub-information, where the number N of receiving links corresponding to the target first sub-information is the same as the number of receiving links supported by the eRedCap UE;

[0161] If the target first sub-information indicates that the eRedCap UE is prohibited from accessing the first cell, determining to prohibit access to the first cell;

[0162] If the target first sub-information indicates that the eRedCap UE is not prohibited from accessing the first cell, it is determined that the UE is allowed to access the first cell.

[0163] In another possible implementation, when the first information includes the second sub-information and / or the third sub-information, the cell access prohibition information may together with the second sub-information and / or the third sub-information indicate whether the eRedCap UE is prohibited from accessing the first cell.

[0164] In this implementation, referring to the flowchart shown in FIG4C , the eRedCap UE may determine whether it is barred from accessing the first cell in the following manner:

[0165] In the first step, the eRedCap UE reads the cell access prohibition information.

[0166] In the second step, the eRedCap UE determines whether the cell access barring information indicates "barred".

[0167] In a third step, if the cell access barring information indicates that the UE is barred from accessing the first cell (ie, indicates "barred"), the eRedCap UE determines to bar the UE from accessing the first cell.

[0168] In the fourth step, if the cell access barring information indicates that the UE is not barred from accessing the first cell (ie, indicates "not barred"), the eRedCap UE obtains the second sub-information and / or the third sub-information.

[0169] In the fifth step, the eRedCap UE may determine whether it is prohibited from accessing the first cell according to the second sub-information and / or the third sub-information and the duplex capability supported by the UE.

[0170] Optionally, determining whether access to the first cell is prohibited based on the second sub-information and / or the third sub-information and the duplex capability supported by the eRedCap UE may be implemented in the following manner:

[0171] Determine the second sub-information or the third sub-information that matches the duplex capability supported by the eRedCap UE;

[0172] If the matched second sub-information or third sub-information indicates that the eRedCap UE is prohibited from accessing the first cell, determining to prohibit access to the first cell;

[0173] If the matched second sub-information or the third sub-information indicates that the eRedCap UE is not prohibited from accessing the first cell, it is determined that access to the first cell is allowed.

[0174] In summary, in the communication processing method provided in the embodiments of the present application, the first information and multiple sub-information configured for the eRedCap UE can be combined with the cell barred information ("cellbarred") in the MIB to indicate the cell access status of the eRedCap UE. This allows the newly introduced cell access control information to be compatible with existing cell access parameters, while also improving the flexibility of network device configuration.

[0175] In another embodiment of the present application, the eRedCap UE may determine whether it is prohibited from accessing the first cell by combining the cell access prohibition information, the relevant access information for the common RedCap UE, and the first information.

[0176] Optionally, the network device can send multiple third information to the terminal device, wherein each third information is used to indicate whether a terminal in the target terminal that supports M receiving links is prohibited from accessing the first cell, M is greater than or equal to 1, and different third information corresponds to different numbers of receiving links M; the target terminal refers to a terminal whose maximum supported bandwidth is less than or equal to 20 MHz.

[0177] It can be understood that the target terminal may be the common RedCap UE introduced in 17. The target terminal may include the eRedCap UE in the embodiment of the present application.

[0178] That is, the third information may be the cell access prohibition information for common RedCap UE introduced in R17 and carried in SIB1.

[0179] In addition, multiple third information may be related to the number of RXs supported by the terminal. Different third information may indicate whether terminals with different numbers of RXs among the target terminals are prohibited from accessing the first cell. Exemplarily, the third information may include "cellBarredRedCap1Rx" and "cellBarredRedCap2Rx".

[0180] In the embodiment of the present application, multiple third information may be used together with the cell access prohibition information and any one of the following to indicate whether the eRedCap UE is prohibited from accessing the first cell:

[0181] First information, multiple first sub-information, second sub-information, and third sub-information.

[0182] In a possible implementation, when the first information is used as separate indication information, multiple third information may be used together with the cell access prohibition information and the first information to indicate whether the eRedCap UE is prohibited from accessing the first cell.

[0183] In this implementation, referring to the flowchart shown in FIG5A , the eRedCap UE may determine whether it is barred from accessing the first cell in the following manner:

[0184] In the first step, the eRedCap UE reads the cell access prohibition information.

[0185] In the second step, the eRedCap UE determines whether the cell access barring information indicates "barred".

[0186] In the third step, if the cell access barring information indicates that access to the first cell is barred (ie, indicates "barred"), the eRedCap UE determines that the first cell is currently barred.

[0187] In the fourth step, if the cell access barring information indicates that access to the first cell is not prohibited (i.e., it indicates "not barred"), the eRedCap UE obtains multiple third information and determines the target third information from the multiple third information, wherein the number of receiving links M corresponding to the target third information is the same as the number of receiving links supported by the eRedCap UE.

[0188] That is, the eRedCap UE may first obtain the third information that matches the number of links it supports from multiple third information to obtain the target third information. Then, the eRedCap UE may determine whether it is allowed to access the first cell based on the specific indication content of the target third information.

[0189] In the fifth step, the eRedCap UE determines whether the target third information indicates that a terminal with M receiving links among the target terminals is prohibited from accessing the first cell.

[0190] In the sixth step, if the target third information indicates that the terminal with M receiving links among the target terminals is prohibited from accessing the first cell, the eRedCap UE determines to prohibit access to the first cell.

[0191] In the seventh step, if the target third information indicates that the terminal with M receiving links in the target terminal is not prohibited from accessing the first cell, the eRedCap UE reads the first information.

[0192] In the eighth step, the RedCap UE determines whether the eRedCap UE is prohibited from accessing the first cell according to the first information.

[0193] Optionally, the eRedCap UE determines, according to the first information, whether the eRedCap UE is prohibited from accessing the first cell, which may be achieved in the following manner:

[0194] If the first information indicates "barred", the eRedCap UE may consider that the current first cell is barred from access. If the first information indicates "notbarred", the eRedCap UE may consider that the current first cell is allowed to access.

[0195] Optionally, the multiple third information in step 4 can replace the barred access indication information for ordinary RedCap UEs, such as "cellBarredRedCap". Correspondingly, the eRedCap UE can directly determine whether "cellBarredRedCap" indicates "barred". If it indicates "barred", the eRedCap UE determines that the current first cell is barred for access. If it indicates "notbarred", it proceeds to step 8.

[0196] In another possible implementation, when the first information includes multiple first sub-information, the multiple third information may jointly indicate whether the eRedCap UE is prohibited from accessing the first cell together with the cell access prohibition information and the multiple first sub-information.

[0197] In this implementation, referring to the flowchart shown in FIG5B , the eRedCap UE may determine whether it is barred from accessing the first cell in the following manner:

[0198] In the first step, the eRedCap UE reads the cell access prohibition information.

[0199] In the second step, the eRedCap UE determines whether the cell access barring information indicates "barred".

[0200] In the third step, if the cell access barring information indicates that the UE is barred from accessing the first cell (i.e., indicates "barred"), the eRedCap UE determines that the UE is barred from accessing the first cell.

[0201] In the fourth step, if the cell access barring information indicates that the UE is not barred from accessing the first cell (i.e., indicates "not barred"), the eRedCap UE determines target third information from the plurality of third information, wherein the number M of receiving links corresponding to the target third information is the same as the number of receiving links supported by the eRedCap UE;

[0202] That is, the eRedCap UE may first obtain the third information that matches the number of links it supports from multiple third information to obtain the target third information. Then, the eRedCap UE may determine whether it is allowed to access the first cell based on the specific indication content of the target third information.

[0203] In the fifth step, the eRedCap UE determines whether the target third information indicates that a terminal with M receiving links among the target terminals is prohibited from accessing the first cell.

[0204] Step 6: If the target third information indicates that the terminal with M receiving links among the target terminals is prohibited from accessing the first cell, the eRedCap UE determines to prohibit access to the first cell;

[0205] In the seventh step, if the target third information indicates that the terminal with M receiving links in the target terminal is not prohibited from accessing the first cell, the eRedCap UE reads multiple first sub-information.

[0206] In the eighth step, the eRedCap UE may determine whether it is prohibited from accessing the first cell according to the number of supported receiving links and the plurality of first sub-information.

[0207] Optionally, the eRedCap UE may determine whether it is prohibited from accessing the first cell based on the number of supported receiving links and the plurality of first sub-information, which may be achieved in the following manner:

[0208] Determine the target first sub-information, where the number N of receiving links corresponding to the target first sub-information is the same as the number of receiving links supported by the eRedCap UE;

[0209] If the target first sub-information indicates that the eRedCap UE is prohibited from accessing the first cell, determining to prohibit access to the first cell;

[0210] If the target first sub-information indicates that the eRedCap UE is not prohibited from accessing the first cell, it is determined that the UE is allowed to access the first cell.

[0211] Optionally, the multiple third information in step 4 can replace the barred access indication information for ordinary RedCap UEs, such as "cellBarredRedCap". Correspondingly, the eRedCap UE can directly determine whether "cellBarredRedCap" indicates "barred". If it indicates "barred", the eRedCap UE determines that the current first cell is barred for access. If it indicates "notbarred", it proceeds to step 8.

[0212] In another possible implementation, when the first information includes the second sub-information and / or the third sub-information, multiple third information can jointly indicate whether the eRedCap UE is prohibited from accessing the first cell together with the cell access prohibition information, and the second sub-information and / or the third sub-information.

[0213] In this implementation, referring to the flowchart shown in FIG5C , the eRedCap UE may determine whether it is barred from accessing the first cell in the following manner:

[0214] In the first step, the eRedCap UE reads the cell access prohibition information.

[0215] In the second step, the eRedCap UE determines whether the cell access barring information indicates "barred".

[0216] In the third step, if the cell access barring information indicates that the UE is barred from accessing the first cell (i.e., indicates "barred"), the eRedCap UE determines that the UE is barred from accessing the first cell.

[0217] In the fourth step, if the cell access barring information indicates that the UE is not barred from accessing the first cell (i.e., indicates "not barred"), the eRedCap UE determines target third information from the plurality of third information, wherein the number M of receiving links corresponding to the target third information is the same as the number of receiving links supported by the eRedCap UE;

[0218] That is, the eRedCap UE may first obtain the third information that matches the number of links it supports from multiple third information to obtain the target third information. Then, the eRedCap UE may determine whether it is allowed to access the first cell based on the specific indication content of the target third information.

[0219] In the fifth step, the eRedCap UE determines whether the target third information indicates that a terminal with M receiving links among the target terminals is prohibited from accessing the first cell.

[0220] Step 6: If the target third information indicates that the terminal with M receiving links among the target terminals is prohibited from accessing the first cell, the eRedCap UE determines to prohibit access to the first cell;

[0221] In the seventh step, if the target third information indicates that the terminal with M receiving links among the target terminals is not prohibited from accessing the first cell, the eRedCap UE reads the second sub-information and / or the third sub-information.

[0222] In the eighth step, the eRedCap UE may determine whether it is prohibited from accessing the first cell according to the second sub-information and / or the third sub-information and the duplex capability supported by the UE.

[0223] Optionally, determining whether access to the first cell is prohibited based on the second sub-information and / or the third sub-information and the duplex capability supported by the eRedCap UE may be implemented in the following manner:

[0224] Determine the second sub-information or the third sub-information that matches the duplex capability supported by the eRedCap UE;

[0225] If the matched second sub-information or third sub-information indicates that the eRedCap UE is prohibited from accessing the first cell, determining to prohibit access to the first cell;

[0226] If the matched second sub-information or the third sub-information indicates that the eRedCap UE is not prohibited from accessing the first cell, it is determined that access to the first cell is allowed.

[0227] Optionally, the multiple third information in step 4 can replace the barred access indication information for ordinary RedCap UEs, such as "cellBarredRedCap". Correspondingly, the eRedCap UE can directly determine whether "cellBarredRedCap" indicates "barred". If it indicates "barred", the eRedCap UE determines that the current first cell is barred for access. If it indicates "notbarred", it proceeds to step 8.

[0228] In summary, in the communication processing method provided in the embodiment of the present application, the first information and multiple sub-information configured for the eRedCap UE can be combined with the cell access barring information ("cellbarred") in the MIB and the cell access barring information of the ordinary RedCap UE (i.e., multiple third information) to jointly indicate the cell access status of the eRedCap UE. This makes the newly introduced cell access control information compatible with the existing cell access parameters and improves the flexibility of network device configuration.

[0229] The following details intra-frequency cell reselection for eRedCap UE.

[0230] In one embodiment of the present application, when the target parameter, i.e., the parameter indicating whether the eRedCap UE is allowed to perform intra-frequency cell reselection, is not configured in the cell access control information, the terminal device may determine that the eRedCap UE is prohibited from accessing the first cell.

[0231] It is understandable that, when there is no parameter in the SIB indicating whether the eRedCap UE is allowed to perform intra-frequency cell reselection, the eRedCap UE may be considered to be prohibited from accessing the current first cell, that is, the current first cell does not support the eRedCap UE.

[0232] It can be seen that the network device can indicate through the first information that the eRedCap UE is prohibited from accessing the first cell without the target parameters, which can reduce the signaling overhead of the configuration information and improve the configuration flexibility of the cell access control.

[0233] In an embodiment of the present application, the first information may include multiple fourth sub-information, and the fourth sub-information is related to the number of RXs supported by the terminal.

[0234] In an embodiment of the present application, each fourth sub-information is used to indicate whether a terminal with L receiving links in the eRedCap UE is allowed to perform intra-frequency cell reselection, where L is greater than or equal to 1, and different fourth sub-information corresponds to different numbers of receiving links L.

[0235] That is, different fourth sub-information may be used to respectively indicate whether terminals with different numbers of receiving links in the eRedCap UE are allowed to perform intra-frequency cell reselection.

[0236] Optionally, "intraFreqReselectionRedCap1RXEnhanced" can be used to indicate whether an eRedCap UE supporting one RX is allowed to perform intra-frequency cell reselection. In addition, "intraFreqReselectionRedCap2RXEnhanced" can be used to indicate whether an eRedCap UE supporting two RXs is allowed to perform intra-frequency cell reselection. It should be noted that the first information can also distinguish eRedCap UEs with more receive links, which are not enumerated one by one in this embodiment of the application.

[0237] For example, if the "intraFreqReselectionRedCap1RXEnhanced" indication is "true", all eRedCap UEs supporting 1 RX in the network can be considered to be able to perform intra-frequency cell reselection after being prohibited from accessing the first cell. If the "intraFreqReselectionRedCap1RXEnhanced" indication is "false", all eRedCap UEs supporting 1 RX in the network can be considered to be not allowed to perform intra-frequency cell reselection after being prohibited from accessing the first cell.

[0238] It can be seen that in the communication processing method provided in the embodiment of the present application, the same-frequency cell reselection information can be separately configured for eRedCap UEs with different numbers of RXs, so as to facilitate the same-frequency cell access control of some terminals in the eRedCap UE. In this way, the granularity of the cell access control is further reduced and the flexibility of the cell access control is improved.

[0239] The following details how the eRedCap UE determines whether it is allowed to perform intra-frequency cell reselection.

[0240] In one embodiment of the present application, the eRedCap UE may determine whether it is allowed to perform intra-frequency reselection according to the following method.

[0241] The eRedCap UE determines whether to allow intra-frequency cell reselection based on the first information;

[0242] or,

[0243] The eRedCap UE determines whether to perform intra-frequency cell reselection based on the number of receiving links it supports and multiple fourth sub-information.

[0244] In a possible implementation, when the first information is used to indicate whether the low-capability terminal is allowed to perform intra-frequency cell reselection, the eRedCap UE may directly determine whether the eRedCap UE is allowed to perform intra-frequency cell reselection according to the indication content of the first information.

[0245] In this implementation, referring to the flowchart shown in FIG6A , the eRedCap UE may determine whether it is barred from accessing the first cell in the following manner:

[0246] The first step is to read the first information.

[0247] Step 2: Determine whether to allow intra-frequency cell reselection based on the first information.

[0248] The eRedCap UE determines whether to allow intra-frequency cell reselection based on the first information, which can be achieved in the following ways:

[0249] Determining whether the first information indicates that the eRedCap UE is allowed to perform intra-frequency cell reselection;

[0250] If the first information indicates that the eRedCap UE is allowed to perform intra-frequency cell reselection, the eRedCap UE determines that intra-frequency cell reselection is allowed after prohibiting access to the current first cell;

[0251] If the first information indicates that the eRedCap UE is not allowed to perform intra-frequency cell reselection, the eRedCap UE determines not to perform intra-frequency cell reselection after prohibiting access to the current first cell.

[0252] In another possible implementation, when the first information includes multiple fourth sub-information, the eRedCap UE may determine whether to allow intra-frequency cell reselection according to the number of receiving links it supports and the multiple fourth sub-information.

[0253] In this implementation, referring to the flowchart shown in FIG6B , the eRedCap UE may determine whether to allow intra-frequency cell reselection according to the following method.

[0254] Step 1: Read multiple fourth sub-information in the SIB;

[0255] Step 2: Determine whether intra-frequency cell reselection is allowed based on the number of supported receiving links and multiple fourth sub-information.

[0256] The eRedCap UE determines whether to allow intra-frequency cell reselection based on the number of supported receive links and multiple fourth sub-information, which can be achieved in the following ways:

[0257] Determine the target fourth sub-information, where the number L of receiving links corresponding to the target fourth sub-information is the same as the number of receiving links supported by the terminal device;

[0258] If the target fourth sub-information indicates that the terminal with L receive links in the eRedCap UE is allowed to perform intra-frequency cell reselection, the eRedCap UE is allowed to perform intra-frequency cell reselection after being prohibited from accessing the first cell;

[0259] If the target fourth sub-information indicates that the terminal with L receiving links in the eRedCap UE is prohibited from performing intra-frequency cell reselection, the eRedCap UE does not perform intra-frequency cell reselection after being prohibited from accessing the first cell.

[0260] It is understood that the eRedCap UE can first obtain the fourth sub-information that matches the number of RXs it supports from multiple fourth sub-information to obtain the target fourth sub-information. Then, the eRedCap UE can determine whether to perform intra-frequency cell reselection based on the specific indication content of the target fourth sub-information.

[0261] For example, in a scenario where the network device uses "intraFreqReselectionRedCap1RXEnhanced" to indicate whether the eRedCap UE supporting 1 RX is allowed to perform intra-frequency cell reselection, and uses "intraFreqReselectionRedCap2RXEnhanced" to indicate whether the eRedCap UE supporting 2 RXs is allowed to perform intra-frequency cell reselection, after the eRedCap UE receives SIB1, it can read the "intraFreqReselectionRedCap2RXEnhanced" or "intraFreqReselectionRedCap2RXEnhanced" carried in SIB1 according to the number of RXs it supports.

[0262] If the eRedCap UE supports 1 RX, the eRedCap UE can read the "intraFreqReselectionRedCap1RXEnhanced" in SIB1. If the information indicates "true", the eRedCap UE can assume that intra-frequency cell reselection can be performed after the first cell is barred from access. If the indication information indicates "false", the eRedCap UE can assume that intra-frequency cell reselection cannot be performed after the current first cell is barred from access. Correspondingly, if the eRedCap UE supports 2 RXs, the eRedCap UE can read the "intraFreqReselectionRedCap1RXEnhanced" in SIB1. If the information indicates "true", the eRedCap UE can assume that intra-frequency cell reselection can be performed after the first cell is barred from access. If the indication information indicates "false", the eRedCap UE can assume that intra-frequency cell reselection cannot be performed after the current first cell is barred from access.

[0263] Optionally, the first information may further include fifth information and / or sixth information. Exemplarily, the fifth sub-information may indicate whether an eRedCap UE supporting half-duplex is allowed to perform intra-frequency cell reselection, and the sixth sub-information is used to indicate whether an eRedCap UE supporting full-duplex is allowed to perform intra-frequency cell reselection.

[0264] Based on this, the eRedCap UE can determine whether it is allowed to perform intra-frequency cell reselection according to the duplex capability supported by itself and the fifth sub-information and / or the sixth sub-information.

[0265] Specifically, the eRedCap UE may determine the fifth sub-information or the sixth sub-information that matches the duplex capability supported by the eRedCap UE;

[0266] If the matched fifth sub-information or sixth sub-information indicates that the eRedCap UE is prohibited from performing intra-frequency cell reselection, it is determined that after access to the first cell is prohibited, intra-frequency cell reselection is prohibited;

[0267] If the matched fifth sub-information or sixth sub-information indicates that the eRedCap UE is allowed to perform intra-frequency cell reselection, it is determined that after prohibiting access to the first cell, intra-frequency cell reselection is allowed.

[0268] For example, in a scenario where the eRedCap UE supports half-duplex capability, the eRedCap UE may select the fifth sub-information to perform the intra-frequency cell reselection judgment process. If the fifth sub-information indicates "true," it can be considered that the eRedCap UE supporting half-duplex can perform intra-frequency cell reselection after being prohibited from accessing the first cell; if the fifth sub-information indicates "false," it can be considered that the eRedCap UE supporting half-duplex is not allowed to perform intra-frequency cell reselection after being prohibited from accessing the current first cell. In a scenario where the eRedCap UE supports full-duplex capability, the sixth sub-information may be selected to perform the intra-frequency cell reselection judgment process. If the sixth sub-information indicates "true," all eRedCap UE supporting full-duplex can be considered to be able to perform intra-frequency cell reselection after being prohibited from accessing the first cell; if the sixth sub-information indicates "false," eRedCap UE supporting full-duplex can be considered to be not allowed to perform intra-frequency cell reselection after being prohibited from accessing the current first cell.

[0269] In summary, the embodiment of the present application configures IFRI parameters separately for the eRedCap UE, and the network can implement more flexible intra-frequency cell reselection control for the eRedCap UE according to different deployments.

[0270] In an embodiment of the present application, the network device may configure second information for one or more neighboring cell frequencies to indicate whether the frequency corresponding to the second information supports eRedCap UE.

[0271] Optionally, in an embodiment of the present application, after receiving at least one second information, the eRedCap UE may use the frequency point that the eRedCap UE is allowed to access as a candidate frequency point for cell reselection based on the at least one second information.

[0272] Exemplarily, the network device can configure a second information on each frequency point for the eRedCap UE. For example, "redCapAccessAllowedEnhanced" indicates whether the eRedCap UE is allowed to access the frequency point. When a frequency band in the inter-frequency frequency point list is configured with the second information, and the second information indicates "true", it means that the eRedCap UE is allowed to access the frequency point. For the eRedCap UE, if the network is configured with an inter-frequency frequency point list, the eRedCap UE will only use those frequencies configured with the redCapAccessAllowedEnhanced indication information as inter-frequency frequency points for cell reselection to set the relevant cell reselection parameters.

[0273] Optionally, in an embodiment of the present application, similar to the above embodiment, the network device may further divide the second information into multiple sub-information according to the number of RXs supported by the terminal and the duplex capability, so as to achieve more refined control over the inter-frequency cell reselection. Exemplarily, the second information may include multiple fifth sub-information, and each fifth information may be used to indicate whether an eRedCap UE with K RXs is allowed to access the current frequency, that is, whether the current frequency supports an eRedCap UE with K RXs. Different fifth sub-information corresponds to different numbers of RXs. Alternatively, the second information may include sixth sub-information and / or seventh sub-information, wherein the sixth sub-information may indicate whether the current frequency supports half-duplex eRedCap UEs, and the seventh sub-information may indicate whether the current frequency supports full-duplex eRedCap UEs.

[0274] In the embodiment of the present application, an inter-frequency access indication is separately configured for the eRedCap UE, and the network can implement more flexible inter-frequency cell reselection control for the eRedCap UE according to different deployments.
