[0046] The following will describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. For the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0047] The embodiments of the present application can be applied to various communication systems, such as: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, Advanced Long Term Evolution (LTE-A) system, New Radio (NR) system, NR system evolution system, LTE on unlicensed spectrum (LTE-U) system, NR on unlicensed spectrum (NR-based access to unlicensed spectrum, NR-U) system, Universal Mobile Telecommunication System (UMTS), Wireless Local Area Networks (WLAN), Wireless Fidelity (WiFi), next generation communication system or other communication systems, etc.

[0048] Generally speaking, traditional communication systems support a limited number of connections and are easy to implement. However, with the development of communication technology, mobile communication systems will not only support traditional communications, but will also support, for example, device to device (Device to Device, D2D) communication, machine to machine (Machine to Machine, M2M) communication, machine type communication (Machine Type Communication, MTC), and vehicle to vehicle (Vehicle to Vehicle, V2V) communication, etc. The embodiments of the present application can also be applied to these communication systems.

[0049] Optionally, the communication system in the embodiment of the present application can be applied to a carrier aggregation (CA) scenario, a dual connectivity (DC) scenario, or a standalone (SA) networking scenario.

[0050] The embodiments of the present application do not limit the spectrum to which they are applied. For example, the embodiments of the present application can be applied to licensed spectrum or unlicensed spectrum.

[0051] For example, the communication system 100 used in the embodiment of the present application is as follows: Figure 1 The communication system 100 may include a network device 110, which may be a device that communicates with a terminal device 120 (or a communication terminal or terminal). The network device 110 may provide communication coverage for a specific geographical area and may communicate with terminal devices located in the coverage area.

[0052] Figure 1 One network device and two terminal devices are shown exemplarily. Optionally, the communication system 100 may include multiple network devices and each network device may include another number of terminal devices within its coverage area, which is not limited in the embodiments of the present application.

[0053] Optionally, the communication system 100 may also include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiments of the present application.

[0054] It should be understood that the device with communication function in the network / system in the embodiment of the present application can be referred to as a communication device. Figure 1 Taking the communication system 100 shown as an example, the communication equipment may include a network device 110 and a terminal device 120 with communication functions. The network device 110 and the terminal device 120 may be the specific devices described above and will not be repeated here. The communication equipment may also include other devices in the communication system 100, such as a network controller, a mobile management entity and other network entities, which is not limited in the embodiments of the present application.

[0055] It should be understood that the terms "system" and "network" are often used interchangeably in this article. The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0056] The embodiments of the present application describe various embodiments in combination with terminal devices and network devices, wherein: the terminal device may also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device, etc. The terminal device may be a station (STAION, ST) in a WLAN, a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA) device, a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, and a next-generation communication system, for example, a terminal device in an NR network or a terminal device in a future evolved Public Land Mobile Network (PLMN) network, etc.

[0057] As an example but not limitation, in the embodiments of the present application, the terminal device may also be a wearable device. Wearable devices may also be referred to as wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also powerful functions achieved through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include full-featured, large-sized, and fully or partially independent of smartphones, such as smart watches or smart glasses, as well as devices that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various types of smart bracelets and smart jewelry for vital sign monitoring.

[0058] The network device can be a device used to communicate with a mobile device. The network device can be an access point (AP) in WLAN, a base station (Base Transceiver Station, BTS) in GSM or CDMA, a base station (NodeB, NB) in WCDMA, an evolved base station (Evolutional Node B, eNB or eNodeB) in LTE, or a relay station or access point, or a vehicle-mounted device, a wearable device, and a network device or base station (gNB) in an NR network, or a network device in a future evolved PLMN network, etc.

[0059] In an embodiment of the present application, a network device provides services for a cell, and a terminal device communicates with the network device through transmission resources (e.g., frequency domain resources, or spectrum resources) used by the cell. The cell may be a cell corresponding to a network device (e.g., a base station). The cell may belong to a macro base station or a base station corresponding to a small cell. The small cells here may include: a metro cell, a micro cell, a picocell, a femtocell, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0060] It should be noted that in NR wireless communication technology, the processing capability of the terminal equipment must meet the processing capability of the maximum bandwidth at the frequency point. At frequencies below 2500MHz, the antenna of the NR terminal equipment must support 1 transmitting antenna and 2 receiving antennas. At higher frequencies (such as frequencies above 2500MHz), NR terminal devices are required to have 4 receiving antennas. The decoding capability of the control channel of the NR terminal equipment is relatively high: for frame structures with subcarrier spacing (SCS) of 15kHz and 30kHz, 56 control channel elements (CCE) are required to be estimated in one time slot; for SCS of 60kHz, 48 CCE channel estimates are required in one time slot; for SCS of 120kHz, 32 CCE channel estimates are required in one time slot. For example, Figure 2 As shown, CCE can be used as the unit of channel estimation for the downlink control channel. Figure 2In the figure, three CCE patterns A, B, and C are shown respectively. In addition, the NR terminal device also requires that the time interval between the physical downlink control channel (PDCCH) and the scheduled physical downlink shared channel (PDSCH) and physical uplink shared channel (PUSCH) be within a certain number of orthogonal frequency-division multiplexing (OFDM) symbols. For example, as shown in Table 1 below, the time interval between PDCCH and the scheduled PDSCH can be within a certain number of OFDM symbols, which is specifically distinguished by the PDSCH having only a pre-demodulation reference signal (DMRS) and the PDSCH having an additional DMRS.

[0061] Table 1

[0062]

[0063] It should also be noted that the new generation of wireless communication technology is evolving towards the Internet of Things (IoT) technology. The 3rd Generation Partnership Project (3GPP) organization promotes the development of machine type communication (MTC) or evolved machine type communication (eMTC), and the Narrow Band Internet of Things (NB-IoT) series of standards have become candidate technical standards for the International Telecommunication Union (ITU) 5G large-scale machine communication technology. The terminals of these technologies have greatly reduced the hardware complexity, data throughput and processing speed of the terminals. It is suitable for some smart home, smart city, smart factory, remote monitoring, and smart transportation application scenarios with lower requirements.

[0064] The 3GPP organization has also promoted another low-latency and high-reliability communication technology for some key communication scenarios. This type of terminal is the NR Ultra-Reliable and Low Latency Communication (URLLC) terminal, which is used in some IoT scenarios that require extremely low latency and extremely high communication reliability, such as video surveillance in smart security, low-latency industrial implementation control, and smart driving. These requirements are also different from ordinary NR terminals. As a key communication technology for ITU 5G, the cost of URLLC terminals is higher than that of ordinary NR terminals.

[0065] Between the above-mentioned large-scale machine communications, critical communications and ordinary NR terminals, NR lacks terminals that define other performance levels. Therefore, the introduction of new levels of terminals will improve the 5G terminal system and better apply it to diversified vertical industries. 3GPP is considering introducing reduced capability (Reduced Capability) terminals that support medium transmission rate and medium latency requirements while having relatively low costs. The reduced terminal complexity is mainly achieved by reducing the supported bandwidth, the number of transceiver antennas, the device size and the processing complexity. Since Reduced Capability terminals have reduced performance such as coverage, throughput, and latency, some networks may not provide services for such terminals.

[0066] In NR and LTE systems, network equipment can indiscriminately restrict user equipment from accessing the network by broadcasting messages, and the access restrictions are independent of the terminal's performance. In addition, terminal equipment cannot report performance restrictions, nor can it report multiple sets of capability information, nor can it configure a certain capability on the network side to enable the terminal equipment to enter a specific low-complexity processing mode.

[0067] Based on the above problems, the present application proposes a solution for accessing a network, whereby a network device can restrict the selection of accessing the network by broadcasting capability levels.

[0068] The technical solution of the present application is described in detail below through specific embodiments.

[0069] Figure 3 is a schematic flow chart of a wireless communication method 200 according to an embodiment of the present application, such as Figure 3 As shown, the method 200 may include but is not limited to the following:

[0070] S210, a network device in a first network broadcasts first information, where the first information includes a capability level threshold, and / or the first information includes a device type that is prohibited or allowed to access the first network, wherein the first information is used to restrict access to the first network;

[0071] S220, the terminal device receives the first information broadcast by the first network.

[0072] In the embodiment of the present application, the first network restricts a certain type of terminal devices from accessing the first network by broadcasting the first information. That is, the network device prohibits or reduces a certain type of terminal devices from accessing the network by broadcasting the message.

[0073] It should be noted that, in the embodiment of the present application, the terminal device may be, for example, a terminal with reduced capability, which supports medium transmission rate and medium delay requirements and has relatively low cost, and its coverage, throughput, delay and other performances are reduced. In addition, in the embodiment of the present application, the terminal device may also be, for example, a terminal with multiple capabilities, which has the ability to work in multiple complexity processing modes, and can work in a specific complexity processing mode through network configuration.

[0074] As embodiment 1, the first information includes a capability level threshold.

[0075] Optionally, in Embodiment 1, when the capability level of the terminal device is lower than the capability level threshold, the terminal device does not preferentially access the first network, or the terminal device does not expect the first network to provide services higher than the capability level of the terminal device.

[0076] It should be noted that the terminal device does not give priority to accessing the first network, which can be understood as the terminal device does not give priority to performing initial access operations on the first network. In addition, the terminal device does not expect the first network to provide services higher than the capability level of the terminal device, which can be understood as the terminal device does not expect a configuration higher than the reported capability when receiving a certain configuration.

[0077] Correspondingly, for the network device, in Example 1, the first information is specifically used to indicate that the terminal device does not give priority to accessing the first network when its capability level is lower than the capability level threshold, or, the first information is specifically used to indicate that the terminal device does not expect the first network to provide services higher than the capability level of the terminal device when its capability level is lower than the capability level threshold.

[0078] Optionally, in Example 1, if the capability level threshold included in the first information is default, when the capability level of the terminal device is lower than the first capability level, the terminal device does not give priority to accessing the first network, or the terminal device does not expect the first network to provide services higher than the capability level of the terminal device.

[0079] Correspondingly, for the network device, in Example 1, if the capability level threshold included in the first information is default, the first information is specifically used to indicate that the terminal device does not give priority to accessing the first network when its capability level is lower than the first capability level, or, the first information is specifically used to indicate that the terminal device does not expect the first network to provide services higher than the capability level of the terminal device when its capability level is lower than the first capability level.

[0080] Optionally, the first capability level is preconfigured, that is, the first capability level is information preconfigured at the terminal device.

[0081] Optionally, the first capability level is the highest capability level of the terminal device.

[0082] Optionally, in embodiment 1, the capability level includes at least one of the following:

[0083] Receiving antenna gain level, transmitting antenna gain level, size level of the terminal device, receiving antenna size level, transmitting antenna size level.

[0084] Optionally, in Embodiment 1, the gain levels of the transmitting and receiving antennas may be, for example, as shown in Table 2 below, or may be as shown in Table 3 below.

[0085] Table 2

[0086]

[0087] Table 3

[0088]

[0089] It should be noted that the values ​​of the receiving antenna and the transmitting antenna in each capability level in Table 2 and Table 3 are merely embodiments and do not limit the specific solutions in this application.

[0090] It should also be noted that the dimensions in the capability level can be independent, such as the transmit and receive antenna gain levels in Table 2 and Table 3 above can be indicated separately. In addition, the capability level can also be extended to the size of the terminal device, the size of the transmit and receive antennas, and can also be extended to power consumption (such as the power consumption of the RF and baseband as a whole), peak rate (such as the peak rate of reception, the peak rate of transmission, etc.), bandwidth (such as the receiving bandwidth, the transmitting bandwidth, etc.) and other types, which are not limited in this application.

[0091] Optionally, in embodiment 1, the first information is master information block (Master Information Block, MIB) information or system information block (System Information Block, SIB) information of a physical broadcast channel (Physical Broadcast Channel, PBCH).

[0092] Optionally, in Embodiment 1, the capability level threshold is indicated by at least one bit of an extended field in the MIB information or the SIB information.

[0093] For example, the extended Reduced Capability Bar domain in the SIB information is a Reduced Capability Bar domain. The Reduced Capability Bar domain can use at least one bit to prohibit access to different capability levels. For example, if the value is 2, terminals with capabilities lower than 2 are prohibited from accessing the network. Furthermore, when the Reduced Capability Bar domain in the SIB information is absent, terminal devices lower than a certain level (such as the highest level) are prohibited from accessing the network.

[0094] As embodiment 2, the first information includes the type of device prohibited or allowed to access the first network.

[0095] In embodiment 2, the terminal device determines whether to access the first network according to the first information. Accordingly, for the network device, in embodiment 2, the first information is specifically used by the terminal device to determine whether to access the first network.

[0096] It should be noted that, in some scenarios, the solutions of the above-mentioned embodiment 1 and embodiment 2 can be combined, that is, the first information includes a capability level threshold and a device type that is prohibited or allowed to access the first network.

[0097] Optionally, in some embodiments, when the first timer times out, the terminal device re-reads the first information broadcast by the first network. Correspondingly, when the first timer times out, the network device re-broadcasts the first information.

[0098] Optionally, the first timer is preconfigured, or the first timer is indicated by the first information, or the first timer is preconfigured for the terminal device by a network device in the first network.

[0099] Optionally, in some embodiments, after the terminal device accesses the first network, the terminal device sends capability information to a network device in the first network. For example, the capability information may reflect information about performance limitations of the terminal device.

[0100] The capability information includes at least one of the following:

[0101] At least one group of transmission capability loss values, at least one group of reception capability loss values, at least one group of blind detection times of a control channel in a unit time, and at least one group of channel estimation times of a control channel unit in a unit time.

[0102] That is to say, in the embodiment of the present application, the terminal device can report multiple sets of capability values ​​by reporting capability information to assist the network device in performing relevant configuration for the terminal device.

[0103] It should be noted that the transmission capability loss value included in the capability information may be specifically the gain reduction value corresponding to the transmitting antenna in Table 2 above, or the transmission capability loss value included in the capability information may be specifically the antenna gain or power corresponding to the transmitting antenna in Table 3 above. Similarly, the receiving capability loss value included in the capability information may be specifically the gain reduction value corresponding to the receiving antenna in Table 2 above, or the receiving capability loss value included in the capability information may be specifically the antenna gain or power corresponding to the receiving antenna in Table 3 above.

[0104] Optionally, the number of blind detections of the control channel within a unit time is related to a frame structure parameter, and / or the number of channel estimations of the control channel unit within a unit time is related to a frame structure parameter.

[0105] For example, the frame structure parameter is a subcarrier spacing (SCS).

[0106] It should be noted that the number of blind detections of the control channel per unit time is related to the frame structure parameters. For example, for 15kHz SCS, the terminal device can perform w blind detections of the control channel in one time slot; for 30kHz SCS, the terminal device can perform x blind detections of the control channel in one slot; for 60kHz SCS, the terminal device can perform y blind detections of the control channel in one slot; for 120kHz SCS, the user can perform z blind detections of the control channel in one slot.

[0107] It should also be noted that the number of channel estimates of the control channel element (CCE) per unit time is related to the frame structure parameters. For example, for 15kHz SCS, the terminal device can perform a CCE channel estimates in one slot; for 30kHz SCS, the terminal device can perform b CCE channel estimates in one slot; for 60kHz SCS, the terminal device can perform c CCE channel estimates in one slot; for 120kHz SCS, the terminal device can perform d CCE channel estimates in one slot.

[0108] Optionally, in some embodiments, the terminal device receives configuration information sent by the network device, where the configuration information is determined based on the capability information; and the terminal device receives and / or detects signals according to the configuration information.

[0109] Correspondingly, after the network device receives the capability information, in response to the capability information, the network device sends configuration information to the terminal device, and the configuration information is used by the terminal device to receive and / or detect signals.

[0110] That is to say, in an embodiment of the present application, the terminal device can report multiple sets of capability values ​​by reporting capability information, and the network device can configure relevant capability values ​​for the terminal device based on the capability information reported by the terminal device, thereby enabling the terminal device to enter a specific processing mode, such as entering a low-complexity processing mode.

[0111] It should be noted that the configuration information is determined based on the capability information, which can be specifically understood as, based on reference to the capability information reported by the terminal device, the network device determines the configuration information so that the terminal device receives and / or detects signals according to the configuration information. The configuration information is determined based on the capability information, which can be specifically understood as, after receiving the capability information reported by the terminal device, the network device selects a group of capabilities in a certain category from the capability information.

[0112] Optionally, the configuration information is used to instruct the terminal device to enable at least one of the following information:

[0113] A group of transmitting capability loss values ​​among the at least one group of transmitting capability loss values, a group of receiving capability loss values ​​among the at least one group of receiving capability loss values, a group of blind detection times of control channels within a unit time among the at least one group of control channel units within a unit time, and a group of channel estimation times of control channel units within a unit time among the at least one group of control channel units within a unit time.

[0114] Specifically, for example, the capability information reported by the terminal device includes four types of capabilities, namely Class A capability, Class B capability, Class C capability and Class D capability, among which Class A capability is the sending capability loss value, and the capability information includes 2 groups of Class A capabilities; Class B capability is the receiving capability loss value, and the capability information includes 3 groups of Class B capabilities; Class C capability is the number of blind detections of the control channel per unit time, and the capability information includes 2 groups of Class C capabilities; Class D capability is the number of channel estimations of the control channel unit per unit time, and the capability information includes 4 groups of Class D capabilities. After receiving the capability information, the network device may, for example, instruct the terminal device to enable only the first group of Class A capabilities (i.e., the network device only instructs the terminal device to enable one type of capability in the capability information) through configuration information; for another example, the network device may instruct the terminal device to enable the first group of Class A capabilities and the first group of Class D capabilities (i.e., the network device instructs the terminal device to enable some types of capabilities in the capability information) through configuration information; for another example, the network device may instruct the terminal device to enable the second group of Class A capabilities, the second group of Class B capabilities, the first group of Class C capabilities, and the fourth group of Class D capabilities (i.e., the network device instructs the terminal device to enable all types of capabilities in the capability information) through configuration information. Further, the terminal device receives and / or detects signals according to the configuration information.

[0115] Optionally, the configuration information is carried in a specific field of downlink control information (DCI) of a physical downlink control channel (PDCCH), or the configuration information is carried in a high-level signaling, such as a radio resource control (RRC) signaling.

[0116] Therefore, in an embodiment of the present application, the first network restricts a certain type of terminal device from accessing the first network by broadcasting the first information. That is, the network device prohibits or reduces a certain type of terminal device from accessing the network by broadcasting a message. Furthermore, the terminal device can report multiple sets of capability values ​​by reporting capability information to assist the network device in performing relevant configurations for the terminal device.

[0120] S330, in response to the capability information, the network device sends configuration information to the terminal device, where the configuration information is used by the terminal device to receive and / or detect signals.

[0121] That is to say, in the embodiment of the present application, the terminal device can report multiple sets of capability values ​​by reporting capability information to assist the network device in performing relevant configuration for the terminal device.

[0122] It should be noted that the transmission capability loss value included in the capability information may be specifically the gain reduction value corresponding to the transmitting antenna in Table 2 above, or the transmission capability loss value included in the capability information may be specifically the antenna gain or power corresponding to the transmitting antenna in Table 3 above. Similarly, the receiving capability loss value included in the capability information may be specifically the gain reduction value corresponding to the receiving antenna in Table 2 above, or the receiving capability loss value included in the capability information may be specifically the antenna gain or power corresponding to the receiving antenna in Table 3 above.

[0123] Optionally, in some embodiments, the number of blind detections of the control channel within a unit time is related to a frame structure parameter, and / or the number of channel estimations of the control channel unit within a unit time is related to a frame structure parameter.

[0124] Optionally, the frame structure parameter is SCS.

[0125] It should be noted that the number of blind detections of the control channel per unit time is related to the frame structure parameters.

[0126] It should also be noted that the number of channel estimates of the control channel element (CCE) per unit time is related to the frame structure parameters.

[0129] That is to say, in an embodiment of the present application, the terminal device can report multiple sets of capability values ​​by reporting capability information, and the network device can configure relevant capability values ​​for the terminal device based on the capability information reported by the terminal device, thereby enabling the terminal device to enter a specific processing mode, such as entering a low-complexity processing mode.

[0130] It should be noted that the configuration information is determined based on the capability information, which can be specifically understood as, based on reference to the capability information reported by the terminal device, the network device determines the configuration information so that the terminal device receives and / or detects signals according to the configuration information. The configuration information is determined based on the capability information, which can be specifically understood as, after receiving the capability information reported by the terminal device, the network device selects a group of capabilities in a certain category from the capability information.

[0133] Specifically, for example, the capability information reported by the terminal device includes four types of capabilities, namely Class A capability, Class B capability, Class C capability and Class D capability, among which Class A capability is the sending capability loss value, and the capability information includes 2 groups of Class A capabilities; Class B capability is the receiving capability loss value, and the capability information includes 3 groups of Class B capabilities; Class C capability is the number of blind detections of the control channel per unit time, and the capability information includes 2 groups of Class C capabilities; Class D capability is the number of channel estimations of the control channel unit per unit time, and the capability information includes 4 groups of Class D capabilities. After receiving the capability information, the network device may, for example, instruct the terminal device to enable only the first group of Class A capabilities (i.e., the network device only instructs the terminal device to enable one type of capability in the capability information) through configuration information; for another example, the network device may instruct the terminal device to enable the first group of Class A capabilities and the first group of Class D capabilities (i.e., the network device instructs the terminal device to enable some types of capabilities in the capability information) through configuration information; for another example, the network device may instruct the terminal device to enable the second group of Class A capabilities, the second group of Class B capabilities, the first group of Class C capabilities, and the fourth group of Class D capabilities (i.e., the network device instructs the terminal device to enable all types of capabilities in the capability information) through configuration information. Further, the terminal device receives and / or detects signals according to the configuration information.

[0134] Optionally, the configuration information is carried in a specific field of the DCI of the PDCCH, or the configuration information is carried in a high-level signaling, such as RRC signaling.

[0135] Therefore, in the embodiment of the present application, the terminal device can report multiple sets of capability values ​​by reporting capability information to assist the network device in performing relevant configuration for the terminal device. The network device can configure relevant capability values ​​for the terminal device according to the capability information reported by the terminal device, so that the terminal device can enter a specific processing mode, such as a low-complexity processing mode.
