[0036] By way of example and not limitation, in this embodiment, the terminal device can also be a wearable device. Wearable devices, also known as wearable smart devices, are a general term for devices that utilize wearable technology to intelligently design and develop everyday wearables, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not merely hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are feature-rich, large in size, and can achieve complete or partial functions without relying on a smartphone, such as smartwatches or smart glasses, as well as those that focus on a specific type of application function and require the use of other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.
[0037] In the embodiments of this application, the network device can be a device for communicating with mobile devices. The network device can be an access point (AP) in WLAN, a base station (BTS) in GSM or CDMA, a base station (NodeB, NB) in WCDMA, an evolved Node B (eNB or eNodeB) in LTE, a relay station or access point, or a vehicle-mounted device, wearable device, or a network device (gNB) in an NR network, or a network device in a future evolved PLMN network or an NTN network, etc.

Optionally, the network device may be a satellite or a balloon station. For example, the satellite may be a low Earth orbit (LEO) satellite, a medium Earth orbit (MEO) satellite, a geostationary earth orbit (GEO) satellite, a high elliptical orbit (HEO) satellite, etc. Optionally, the network device may also be a base station located on land, water, or other similar locations.
[0039] In this embodiment, the network device can provide services to a cell. The terminal device communicates with the network device through the transmission resources (e.g., frequency domain resources, or spectrum resources) used by the cell. The cell can be the cell corresponding to the network device (e.g., a base station). The cell can belong to a macro base station or to a base station corresponding to a small cell. The small cell can include: metro cell, micro cell, pico cell, femto cell, etc. These small cells have the characteristics of small coverage area and low transmission power, and are suitable for providing high-speed data transmission services.
[0040] For example, the communication system 100 used in the embodiments of this application is as follows: Figure 1 As shown. 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, terminal). The network device 110 can provide communication coverage for a specific geographical area and can communicate with terminal devices located within that coverage area.
[0041] Figure 1An exemplary embodiment shows a network device and two terminal devices. Optionally, the communication system 100 may include multiple network devices and each network device may include other numbers of terminal devices within its coverage area. This application embodiment does not limit this.
[0042] 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 this embodiment.
[0043] It should be understood that devices with communication functions in the network / system of this application embodiment can be referred to as communication devices. 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, which will not be repeated here. The communication equipment may also include other devices in the communication system 100, such as network controllers, mobility management entities and other network entities. This application embodiment does not limit this.
[0044] It should be understood that the terms "system" and "network" are often used interchangeably in this document. The term "and / or" in this document merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Furthermore, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.
[0045] It should be understood that the term "instruction" mentioned in the embodiments of this application can be a direct instruction, an indirect instruction, or an indication of a relationship. For example, A instructing B can mean that A directly instructs B, such as B being able to obtain information through A; it can also mean that A indirectly instructs B, such as A instructing C, so B can obtain information through C; or it can mean that there is a relationship between A and B.
[0046] In the description of the embodiments of this application, the term "correspondence" may indicate that there is a direct or indirect correspondence between two things, or that there is an association between two things, or that there is a relationship of instruction and being instructed, configuration and being configured, etc.
[0047] In this application embodiment, "predefined" can be achieved by pre-storing corresponding codes, tables, or other means that can be used to indicate relevant information in the device (e.g., including terminal devices and network devices). This application does not limit the specific implementation method. For example, predefined can refer to what is defined in the protocol.
[0048] In this application embodiment, the "protocol" may refer to a standard protocol in the field of communication, such as the LTE protocol, the NR protocol, and related protocols applied to future communication systems. This application does not limit this.
[0049] In NR systems, two random access methods are supported: contention-based random access and non-contention-based random access. Specifically, terminal devices can select Physical Random Access Channel (PRACH) resources, which can include time-domain, frequency-domain, and code-domain resources. Network devices send random access-related parameters to terminal devices via a System Information Block (SIB). The Reference Signal Received Power (RSRP) threshold (rsrp-ThresholdSSB) for the Synchronization Signal Block (SSB) in the Random Access Common Configuration Information Element (RACH-ConfigCommon IE) is used by the terminal device for SSB selection. The terminal device compares the RSRP measurement result for each SSB with the rsrp-ThresholdSSB and selects the SSB with a measured value higher than the configured threshold for access.
[0050] Version 17 (R17) introduced RedCap endpoints, or RedCap devices, for scenarios with lower performance requirements. Examples include, but are not limited to, the following scenarios:
[0051] Scenario 1: Industrial Wireless Sensors. Compared to Ultra-Reliable and Low-Latency Communication (URLLC) terminals, industrial wireless sensors have relatively lower latency and reliability requirements. Furthermore, their device cost and power consumption are lower than URLLC terminals and Enhanced Mobile Broadband (eMBB) terminals.
[0052] Scenario 2: Video surveillance can be used in smart cities, industrial processes, and other similar scenarios. In smart city scenarios, the equipment is mainly used for data collection and processing, thereby enabling more effective monitoring and control of urban resources and providing more efficient services to city residents.
[0053] Scenario 3: Wearables. Examples include, but are not limited to, smartwatches, rings, electronic health devices, and medical monitoring devices. These devices are typically small in size.
[0054] Therefore, terminals supporting the above scenarios have reduced capabilities compared to other terminals, such as reduced supported bandwidth, relaxed processing time, and fewer antennas. Due to the reduced capabilities, such as fewer receiving antennas or reduced antenna gain, the RSRP measurement results of RedCap terminals for SSBs will be lower than those of non-RedCap terminals. Thus, if RedCap terminals decide on the selected SSB based on the RSRP threshold of non-RedCap terminals, the RedCap terminals will be unable to find SSBs that meet the RSRP threshold, thereby failing to obtain the corresponding PRACH resources and affecting subsequent random access procedures.
[0055] Figure 2 This is a schematic flowchart illustrating a wireless communication method 200 provided in an embodiment of this application. The method 200 can be... Figure 1 The terminal device in the communication system shown performs, such as Figure 2 As shown, the method 200 may include at least some of the following:
[0056] S210, the terminal device determines the target reference signal measurement threshold used by the terminal device according to the first reference signal measurement threshold, wherein the first reference signal measurement threshold is the reference signal measurement threshold corresponding to the first type of terminal, the terminal device belongs to the first type of terminal, and the first type of terminal includes reduced capability terminals.
[0057] In some embodiments, the target reference signal measurement threshold is the first reference signal measurement threshold.
[0058] Optionally, in the embodiments of this application, at least two types of terminals may be included, such as a first type of terminal and a second type of terminal. In some embodiments, the at least two types of terminals may be divided according to the capabilities of the terminal devices, or they may be divided according to the differences in the measurement results of the terminal devices for the reference signal. This application is not limited thereto.
[0059] Optionally, the capabilities of the terminal device may include at least one of the following: the number of receiving antennas, the receiving antenna gain, and the coverage capability level. Alternatively, it may include other performance indicators that may affect the receiving capability (or receiving performance, affecting the reference signal measurement results), and this application is not limited thereto.
[0060] Optionally, the coverage capability level can be expressed as the reception capability level of the terminal device, which is proportional to the number of receiving antennas and the receiving antenna gain of the terminal device. That is, the more receiving antennas there are, the higher the coverage capability level, and the greater the receiving antenna gain, the higher the coverage capability level.
[0061] In some embodiments of this application, the network device can configure corresponding reference signal measurement thresholds for different types of terminals. For example, a first reference signal measurement threshold can be configured for the first type of terminal, and a second reference signal measurement threshold can be configured for the second type of terminal. In this way, different types of terminals can use the corresponding reference signal measurement thresholds to select reference signals, which is beneficial to selecting a suitable reference signal.
[0062] It should be understood that the first type of terminal can be any type of terminal that requires configuration of differentiated reference signal measurements. For example, the capabilities of the first type of terminal and the second type of terminal may differ. More specifically, the capabilities of the first type of terminal may be lower than those of the second type of terminal, or vice versa.
[0063] In some embodiments, the first type of terminal includes a reduced-capability terminal, i.e., a RedCap terminal. The second type of terminal includes a normal terminal, wherein the normal terminal has higher capabilities than the reduced-capability terminal. In other words, the capabilities of the first type of terminal are lower than those of the second type of terminal.
[0064] In other embodiments, the first type of terminal includes an enhanced-capability terminal. The second type of terminal includes a regular terminal. The capabilities of the regular terminal are lower than those of the enhanced-capability terminal. In other words, the capabilities of the first type of terminal are higher than those of the second type of terminal.
[0065] In this embodiment of the application, by configuring independent reference signal measurement thresholds for terminals with significantly different capabilities from the second type of terminals, these terminals can use the corresponding reference signal measurement thresholds to select reference signals, which is beneficial for selecting suitable reference signals.
[0066] In some embodiments, the reduced-capability terminal may include terminals in the three scenarios described above, or it may also include terminals in machine-type communication (MTC) or evolved machine-type communication (eMTC), narrowband Internet of Things (NB-IoT), etc. Terminals in these technologies greatly reduce the hardware complexity, data throughput and processing speed of the terminal, so they can also be called reduced-capability terminals. Alternatively, it may include terminals applied in some low-requirement smart home, smart city, smart factory, remote monitoring and smart transportation application scenarios. This application is not limited to these.
[0067] It should be understood that in the embodiments of this application, the term "reduced capability terminal" can also be replaced with other terms to indicate a type of terminal with lower performance requirements such as latency, reliability, bandwidth, coverage, and throughput, or a terminal with lower capability, or a type of terminal with lower reference signal measurement results, etc. The same applies to enhanced capability terminals, and this application does not limit this.
[0068] The following description uses the first type of terminal as a reduced-capability terminal and the second type of terminal as a normal terminal as an example, but this application is not limited thereto.
[0069] In some embodiments, if the first type of terminal is a de-capacitated terminal and the second type of terminal is a normal terminal, since the capability of the normal terminal is higher than that of the de-capacitated terminal, the measurement result of the downlink reference channel measured by the normal terminal is usually higher than the measurement result of the downlink reference signal measured by the de-capacitated terminal.
[0070] Therefore, in some embodiments, the threshold for the first reference signal measurement of the first type of terminal can be configured to be smaller than the threshold for the second reference signal measurement of the second type of terminal, which is beneficial to reduce the difficulty for the terminal to select a suitable downlink reference signal.
[0071] In some embodiments, the first reference signal measurement threshold may be configured through system information, such as the Random Access Common IE (RACH-ConfigCommon IE) included in the system information.
[0072] In other embodiments, the first reference signal measurement threshold can also be configured via other signaling or messages, such as via Radio Resource Control (RRC) signaling or paging messages.
[0073] In this embodiment, the first type of terminal includes multiple sub-terminal types. Further, the network device can be configured with multiple first reference signal measurement thresholds, and each of the multiple sub-terminal types corresponds to one first reference signal measurement threshold. Each of the multiple sub-terminal types corresponds to a specific capability; that is, the capabilities of each sub-terminal type can also be different.
[0074] In other words, network devices can determine the corresponding reference signal measurement thresholds for different types of degraded terminals. In this way, different types of degraded terminals can determine their sub-terminal type based on their own capabilities, and further determine the reference signal measurement threshold corresponding to that sub-terminal type as the target reference signal measurement threshold.
[0075] In some embodiments, the first reference signal measurement threshold can be used for the selection of a downlink reference signal.
[0076] For example, the terminal device can determine a downlink reference signal that satisfies the first reference signal measurement threshold as a target reference signal based on the measurement results of the downlink reference signal and the first reference signal measurement threshold.
[0077] Further, based on the target reference signal and the first correlation relationship, physical random access channel (PRACH) resources are determined, wherein the first correlation relationship is the correlation between the downlink reference signal and the PRACH resources.
[0078] Optionally, in embodiments of this application, the downlink reference signal includes, but is not limited to, at least one of the following: Synchronization Signal Block (SSB), Channel State Information Reference Signal (CSI-RS), and Demodulation Reference Signal (DMRS).
[0079] It should be noted that in the embodiments of this application, SSB can also be called SS block, or synchronization signal / physical broadcast channel block (SS / PBCH block).
[0080] Optionally, the measurement results of the downlink reference signal may be, for example, but not limited to, at least one of the following: Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), Signal to Interference plus Noise Ratio (SINR), and Channel Quality Indicator (CQI).
[0081] As an example, the threshold for the first reference signal measurement can be the RSRP threshold.
[0082] In other embodiments, the first reference signal measurement threshold can be used for the selection of a random access type.
[0083] In some embodiments, when the terminal device supports both 4-step random access and 2-step random access types, the terminal device determines which random access type to use to initiate random access based on the first reference signal measurement threshold.
[0084] For example, if the measurement result of the downlink reference signal is greater than the measurement threshold of the first reference signal, a two-step random access type can be selected.
[0085] Therefore, by configuring an appropriate reference signal measurement threshold for the reduced-capability terminal, the reduced-capability terminal can select the appropriate random access type based on the threshold, which helps to improve the probability of successful random access.
[0086] In some other embodiments, the first reference signal measurement threshold can be used to select the carrier used to initiate random access. This first reference signal measurement threshold can also be referred to as the Supplementary Uplink (SUL) carrier selection threshold, meaning that the first reference signal measurement threshold can be used by the terminal device to determine whether to initiate random access on the SUL carrier.
[0087] For example, if the measurement result of the downlink reference signal is greater than the measurement threshold of the first reference signal, the terminal device can select the SUL carrier; otherwise, it can select the normal uplink (NU) carrier.
[0088] Therefore, by configuring a suitable reference signal measurement threshold for the reduced-capability terminal, the reduced-capability terminal can select a suitable carrier to initiate random access based on the threshold, which helps to improve the probability of successful random access.
[0089] It should be understood that the application of the above reference signal measurement threshold is only an example. The reference signal measurement threshold can also be applied to other scenarios where the downlink reference signal is measured and subsequent operations are performed based on the measurement results. This application is not limited to this.
[0090] Figure 3 This is a schematic flowchart illustrating another wireless communication method 300 provided in an embodiment of this application. Method 300 can be... Figure 1 The terminal device in the communication system shown performs, such as Figure 3 As shown, the method 300 may include at least some of the following:
[0091] S310, the terminal device determines the target reference signal measurement threshold used by the terminal device based on the reference signal measurement threshold corresponding to the second type of terminal and the capability of the first type of terminal, wherein the terminal device belongs to the first type of terminal, the first type of terminal includes terminals with reduced capability, and the second type of terminal does not include terminals with reduced capability.
[0092] It should be understood that, in this embodiment, the meanings of the first type of terminal and the second type of terminal can be referred to the relevant description in method 200, and will not be repeated here.
[0093] In this embodiment, the network device may not configure an independent reference signal measurement threshold for the first type of terminal. The terminal device can determine the reference signal measurement threshold applicable to the first type of terminal based on the reference signal measurement threshold corresponding to the second type of terminal.
[0094] In other words, network devices can be configured with only the reference signal measurement thresholds for the second type of terminal, while the reference signal measurement thresholds for other types of terminals can be determined based on the reference signal measurement thresholds for the second type of terminal.
[0095] In some embodiments, the terminal device may determine the target reference signal measurement threshold used by the terminal device based on the reference signal measurement threshold corresponding to the second type of terminal and in combination with the capabilities of the first type of terminal.
[0096] For example, if the capability of the first type of terminal is lower than that of the second type of terminal, the terminal device can determine that the reference signal measurement threshold corresponding to the first type of terminal is lower than the reference signal measurement threshold corresponding to the second type of terminal.
[0097] As an example, the reference signal measurement threshold corresponding to the second type of terminal is added to an offset and the result is determined as the reference signal measurement threshold corresponding to the first type of terminal, where the offset is a negative number.
[0098] For example, if the capability of the first type of terminal is higher than that of the second type of terminal, the terminal device can determine that the reference signal measurement threshold corresponding to the first type of terminal is higher than the reference signal measurement threshold corresponding to the second type of terminal.
[0099] As an example, the reference signal measurement threshold corresponding to the second type of terminal is added to an offset and the result is determined as the reference signal measurement threshold corresponding to the first type of terminal, wherein the offset is a positive number.
[0100] In one specific embodiment, the terminal device can determine a first adjustment amount based on the capabilities of the first type of terminal and the second type of terminal, and further determine the target reference signal measurement threshold based on the reference signal measurement threshold corresponding to the second type of terminal and the first adjustment amount.
[0101] In some embodiments, the reference signal measurement threshold corresponding to the second type of terminal can be represented by the RSRP range. In some cases, the RSRP range is 0-127, and the actual RSRP threshold value is obtained by subtracting 156 dBm from this value. Except for the case where the value is 127, the actual RSRP threshold value is infinite. The RSRP range corresponds to the range of the measured RSRP. Table 1 is an example of RSRP range.
[0102] Table 1
[0103]
[0104]
[0105] For example, if the second type of terminal supports a frequency band with a minimum number of receiving antennas of 2, and the first type of terminal supports a frequency band with a number of receiving antennas of 1, then the first adjustment amount can be determined to be -3dBm.
[0106] For the second type of terminal, the actual RSRP threshold value is obtained by subtracting 156dBm from the RSRP range in Table 1. For the first type of terminal, the actual RSRP threshold value is obtained by subtracting 156dBm from the RSRP range in Table 1, and then subtracting 3dBm.
[0107] For example, if the network device indicates that the reference signal measurement threshold for the Type 2 terminal is 10, then the calculated actual RSRP threshold for the Type 2 terminal is -146 dBm. This corresponds to the RSRP range of [-146, -145) dBm in the table above. For the Type 2 terminal, the calculated actual RSRP threshold is -149 dBm. This corresponds to the RSRP range of [-149, -148) dBm in the table above.
[0108] For example, if the second type of terminal supports a frequency band with a minimum of 2 receiving antennas, and the first type of terminal supports a frequency band with a minimum of 1 receiving antenna, and the receiving antenna gain of the first type of terminal is 3dB lower than that of the second type of terminal, then the first adjustment amount can be determined to be -6dBm.
[0109] The second type of terminal obtains its actual RSRP threshold value by subtracting 156dBm from the RSRP range in Table 1. The first type of terminal obtains its actual RSRP threshold value by subtracting 156dBm from the RSRP range in Table 1, and then subtracting 6dBm.
[0110] For example, if the network device indicates that the reference signal measurement threshold for the Type 2 terminal is 10, then the calculated actual RSRP threshold for the Type 2 terminal is -146 dBm. This corresponds to the RSRP range of [-146, -145) dBm in the table above. For the Type 2 terminal, the calculated actual RSRP threshold is -152 dBm. This corresponds to the RSRP range of [-152, -151) dBm in the table above.
[0111] It should be understood that the above-described method for determining the first adjustment amount is merely an example. In other embodiments, the first adjustment amount may also be other values, and this application is not limited thereto.
[0112] It should also be understood that, in the embodiments of this application, the method of determining the reference signal measurement threshold corresponding to the first type of terminal based on the capability of the first type of terminal is only an example. In other embodiments, the terminal device may also determine its corresponding reference signal measurement threshold according to other algorithms. For example, there may be a specific offset between the reference signal measurement threshold corresponding to the first type of terminal and the reference signal measurement threshold corresponding to the second type of terminal. This specific offset may be predefined, such as 3dB, or it may be configured by the network device.
[0113] Therefore, in this embodiment, it is not necessary to add a new reference signal measurement threshold. The terminal device determines its own target reference signal measurement threshold according to the reference signal measurement threshold configured by the network device based on a preset algorithm. This helps to reduce signaling overhead, requires less modification to the existing protocol, and helps to maintain backward compatibility.
[0114] In this embodiment of the application, the first type of terminal includes multiple sub-terminal types, each of which corresponds to a specific capability, that is, the capabilities of each sub-terminal type are also different.
[0115] Optionally, in some embodiments, each sub-terminal type corresponds to a specific adjustment amount.
[0116] For example, the adjustment amount corresponding to the first sub-terminal type is -3dB, and the adjustment amount corresponding to the second sub-terminal type is -6dB. The capability of the first sub-terminal type is higher than that of the second sub-terminal type.
[0117] The terminal device can then determine its sub-terminal type based on its own capabilities, and further determine the target adjustment amount based on its sub-terminal type.
[0118] In this embodiment, the application of the reference signal measurement threshold corresponding to the first type of terminal determined by the terminal device can refer to the relevant implementation in method 200, and will not be described again here for the sake of brevity.
[0119] In some embodiments, the reference signal measurement threshold corresponding to the first type of terminal can be used for the selection of downlink reference signals.
[0120] In other embodiments, the reference signal measurement threshold corresponding to the first type of terminal can be used for the selection of random access type.
[0121] In some other embodiments, the reference signal measurement threshold corresponding to the first type of terminal can be used to select the carrier used to initiate random access.
[0122] In summary, the network device can configure a dedicated reference signal measurement threshold for the first type of terminal, or the terminal device can determine the reference signal measurement threshold for the first type of terminal based on the reference signal measurement threshold for the second type of terminal and the capabilities of the first type of terminal. Furthermore, when the first type of terminal selects a reference signal based on the reference signal measurement threshold, it is beneficial to ensure that a suitable reference signal is selected, thereby ensuring subsequent data communication.
