A wearable device may also be referred to as a wearable smart device, and is a general term for developing wearable devices by applying wearable technology to everyday wear and performing smart design, 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 a user's clothing or accessories. A wearable device is not merely a hardware device, but furthermore implements powerful functions through software support, data interaction, and cloud interaction. In a broad sense, wearable smart devices include devices that are functional, large in size, and capable of implementing all or part of functions without relying on a smartphone, such as smart watches or smart glasses, and also devices that focus only on certain types of application functions and must be used in combination with other devices, such as smartphones, such as various smart bands and smart accessories that perform vital sign detection.

[0031] For example, the communication system (100) used by an embodiment of the present application is as illustrated in FIG. 1. The communication system (100) may include a network device (110), and the network device (110) may be a device that communicates with a terminal device (120) (or a communication device, referred to as a terminal). The network device (110) may provide a communication cover for a specified geographical area and may also communicate with a terminal device located within the coverage area.

[0032] FIG. 1 illustrates, by way of example, one network device and two terminal devices, but optionally, the communication system (100) may include multiple network devices and may also include other quantities of terminal devices within the coverage of each network device, and embodiments of the present application are not limited thereto.

[0033] Optionally, the communication system (100) may also include other network entities such as a network controller, a mobile management entity, etc., and embodiments of the present application are not limited thereto.

[0034] It will be understood that a device equipped with a communication function in a network / system among the embodiments of the present application may be referred to as a communication device. Taking the communication system (100) illustrated in FIG. 1 as an example, the communication device may include a network device (110) and a terminal device (120) equipped with a communication function, and the network device (110) and the terminal device (120) may be specific devices described above, and a detailed description is omitted here; the communication device may also include other devices in the communication system (100), such as a network controller, a mobile management entity, and other network entities, and the embodiments of the present application are not limited thereto.

[0035] The terms “system” and “network” in this specification may be used interchangeably as usual. The term “and / or” in this specification is used merely to describe the relationship between related objectives and indicates that three relationships may exist; for example, A and / or B may represent three situations where A exists alone, where A and B exist simultaneously, or where B exists alone. Furthermore, in this specification, the symbol “ / ” generally indicates that the related objects are in an “or” relationship.

[0036] It should be understood that the “indications” presented in the embodiments of this application may indicate directly or indirectly, or may indicate associations. For example, if A indicates B, it may indicate that A directly indicates B, for example, that B can be obtained through A; it may also indicate that A indirectly indicates B, for example, if A indicates C, that B can be obtained through C; and it may also indicate that there is an association between A and B.

[0037] In the description of the embodiments of the present application, the term “correspondence” may indicate a direct or indirect correspondence relationship between two entities, an association relationship between two entities, or a relationship such as between a director and the directed, or between a component and the component.

[0038] In embodiments of the present application, "pre-definition" may be implemented by storing in advance a method that can be used to indicate a code, table, or other related information corresponding to a device (e.g., including terminal devices and network devices), and the present application does not limit the specific implementation method thereof. For example, pre-definition may refer to what is defined in a protocol.

[0039] In the embodiments of the present application, the "protocol" may refer to standard protocols in the field of communication, and may include, for example, LTE protocols, NR protocols, and related protocols to be applied to future communication systems, and the present application is not limited thereto.

[0040] In an NR system, two random access methods can be supported: a contention-based random access method and a non-contention-based random access method. Specifically, a terminal device can select a Physical Random Access Channel (PRACH) resource, and the PRACH resource may include time domain resources, frequency domain resources, and code domain resources. A network device transmits random access-related parameters to a terminal device via a broadcast System Information Block (SIB), wherein the Reference Signal Receiving Power (RSRP) threshold (rsrp-ThresholdSSB) for the Synchronization Signal Block (SSB) among the Random Access Common Configuration Information Elements (RACH-ConfigCommon IE) is used by the terminal device to perform SSB selection, and the terminal device compares the RSRP measurement result under each SSB with the rsrp-ThresholdSSB and selects and connects to an SSB in which the measurement value is higher than the configured threshold.

[0041] In version 17 (R17), RedCap terminals are introduced, referred to as RedCap devices, and are used in situations where performance requirements are low. For example, this applies to, but is not limited to, the following situations.

[0042] Situation 1: Industrial wireless sensors require relatively low delay and reliability compared to Ultra-Reliable and Low Latency Communication (URLLC) terminals. Additionally, device costs and power consumption are lower than those of URLLC terminals and Enhanced Mobile Broadband (eMBB) terminals.

[0043] Situation 2: Video surveillance can be utilized in situations such as smart cities and industrial processes. In a smart city setting, the device is primarily used for data collection and processing, enabling more effective monitoring and control of urban resources and the provision of more effective services to urban residents.

[0044] Situation 3: It is a wearable device. Examples include, but are not limited to, smartwatches, rings, electronic health devices, medical monitoring devices, etc. The size of these devices is usually relatively small.

[0045] Therefore, the terminal supporting the above-described situation is inferior to the capabilities of other devices, such as reduced supported bandwidth, loosened processing time, or reduced number of antennas. Due to this reduction in capability, for example, if the number of receiving antennas is reduced or the antenna gain is reduced, the measurement result of RSRP for the SSB of the RedCap terminal is inferior to that of the non-RedCap terminal. Consequently, if the RedCap terminal determines the SSB selected by the RSRP threshold of the non-RedCap terminal, the RedCap terminal cannot find an SSB that satisfies the RSRP threshold, cannot acquire the corresponding PRACH resource, and this affects the subsequent random access process.

[0046] FIG. 2 is an exemplary flowchart of a wireless communication method (200) provided by an embodiment of the present application. The method (200) can be executed by a terminal device among the communication systems shown in FIG. 1, and as shown in FIG. 2, the method (200) may include at least some of the following contents.

[0047] S210, the terminal device determines a target reference signal measurement threshold used by the terminal device by a first reference signal measurement threshold, wherein the first reference signal measurement threshold is a reference signal measurement threshold corresponding to a first type terminal, the terminal device belongs to the first type terminal, and the first type terminal includes a capability reduction terminal.

[0048] In some embodiments, the target reference signal measurement threshold is the first reference signal measurement threshold.

[0049] Optionally, in embodiments of the present application, at least two types of terminals may be included, for example, a first type terminal and a second type terminal, and in some embodiments, the at least two types of terminals may be distinguished by the capability of the terminal device or by a difference in the measurement result with respect to the reference signal of the terminal device, and the present application is not limited thereto.

[0050] Optionally, the capabilities of the terminal device may include, for example, at least one of the number of receiving antennas, receiving antenna gain, and coverage capability class. Alternatively, it may include other performance indicators that may affect receiving capability (or receiving performance, influence on reference signal measurement results), and the present application is not limited thereto.

[0051] Optionally, the coverage capability class can be expressed as the reception capability class of the terminal device, which is directly 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 class, and the greater the receiving antenna gain, the higher the coverage capability class.

[0052] In some embodiments of the present application, the network device may configure corresponding reference signal measurement thresholds for different types of terminals, for example, configuring a first reference signal measurement threshold for a first type of terminal and a second reference signal measurement threshold for a second type of terminal, so that the different types of terminals can select a reference signal using the corresponding reference signal measurement thresholds, which is advantageous for selecting an appropriate reference signal.

[0053] It should be understood that the above-mentioned first-type terminal may be any one type of terminal requiring a differential reference signal measurement quantity configuration. For example, the capabilities of the above-mentioned first-type terminal and the above-mentioned second-type terminal are different from each other. More specifically, the capability of the above-mentioned first-type terminal may be lower than that of the above-mentioned second-type terminal, or the capability of the above-mentioned first-type terminal may be higher than that of the above-mentioned second-type terminal, etc.

[0054] In some embodiments, the first type terminal includes a reduced capability terminal, i.e., a RedCap terminal. The second type terminal includes a general terminal, wherein the capability of the general terminal is higher than the capability of the reduced capability terminal. In other words, the capability of the first type terminal is lower than the capability of the second type terminal.

[0055] In some other embodiments, the first type terminal includes an enhanced capability terminal. The second type terminal includes a standard terminal. Here, the capability of the standard terminal is lower than the capability of the enhanced capability terminal. In other words, the capability of the first type terminal is higher than the capability of the second type terminal.

[0056] In an embodiment of the present application, by configuring a reference signal measurement threshold independent of a terminal that differs significantly from the capability of a second type terminal, the terminal of this type can perform a selection of a reference signal using a corresponding reference signal measurement threshold, and is advantageous for selecting a suitable reference signal.

[0057] In some embodiments, the reduced capability terminal may include a terminal in any of the three aforementioned situations, or may include a terminal in machine type of communication (MTC), evolved machine type of communication (eMTC), or Narrow Band Internet of Things (NB-IoT), and a terminal in any of these technologies may also be referred to as a reduced capability terminal because it significantly reduces the hardware complexity, data throughput, and processing speed of the terminal, or may include a terminal applied in smart home, smart city, smart factory, remote monitoring, or smart transportation application situations where some requirements are low, and the present application is not limited thereto.

[0058] It should be understood that, in the embodiments of this application, the capability-reduced terminal may also be replaced by other expressions to refer to a terminal device with low performance requirements such as a type of time delay, reliability, bandwidth, coverage, or throughput, or a terminal device with low capability, or a terminal of a type with a low reference signal measurement result, and the same applies to capability-enhanced terminals, and this application is not limited thereto.

[0059] The following describes the above-mentioned first-type terminal as a reduced-capacity terminal and the above-mentioned second-type terminal as a general terminal, but the present application is not limited thereto.

[0060] In some embodiments, if the first type terminal is a reduced capability terminal and the second type terminal is a general terminal, the measurement result of the downlink reference channel measured by the general terminal is generally higher than the measurement result of the downlink reference signal measured by the reduced capability terminal because the capability of the general terminal is higher than the capability of the reduced capability terminal.

[0061] Accordingly, in some embodiments, the first reference signal measurement threshold corresponding to the first type terminal can be configured to be smaller than the second reference signal measurement threshold corresponding to the second type terminal, which is advantageous for the capability-reduced terminal to select a suitable downlink reference signal.

[0062] In some embodiments, the first reference signal measurement threshold may be configured through system information, for example, and may be included in the random access common configuration (RACH-ConfigCommon IE) among the system information.

[0063] In another embodiment, the first reference signal measurement threshold may also be configured through other signals or messages, such as through Radio Resource Control (RRC) signals or paging messages.

[0064] In an embodiment of the present application, the first type terminal includes multiple types of sub-terminals, and furthermore, the network device may configure multiple first reference signal measurement threshold values, and each of the various sub-terminal types corresponds to one of the first reference signal measurement threshold values. Here, each of the various sub-terminal types corresponds to a specific capability, that is, the capabilities of the various sub-terminal types may differ from one another.

[0065] In other words, the network device can determine a corresponding reference signal measurement threshold for each target of different types of capability-reduced terminals, and in this way, different types of capability-reduced terminals can determine their affiliated sub-terminal type based on their own capability, and furthermore, determine the reference signal measurement threshold corresponding to the corresponding sub-terminal type as the target reference signal measurement threshold.

[0066] In some embodiments, the first reference signal measurement threshold can be used for selecting a downlink reference signal.

[0067] For example, the terminal device may determine a downlink reference signal satisfying the first reference signal measurement threshold as a target reference signal based on the measurement result of the downlink reference signal and the first reference signal measurement threshold.

[0068] Further, a physical random access channel (PRACH) resource is determined by the above-mentioned target reference signal and a first relationship, wherein the first relationship is the relationship between the downlink reference signal and the PRACH resource.

[0069] Optionally, in an embodiment of the present application, the downlink reference signal includes, but is not limited to, at least one of a Synchronization Signal Block (SSB), a Channel State Information Reference Signal (CSI-RS), and a Demodulation Reference Signal (DMRS).

[0070] As to be explained, in the embodiments of the present application, the SSB may also be referred to as the SS block, or the Synchronization signal / physical broadcast channel block (SS / PBCH block).

[0071] Optionally, the measurement result of the downlink reference signal may be at least one of, for example, Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), Signal to Interference plus Noise Ratio (SINR), and Channel Quantity Indicator (CQI), but is not limited thereto.

[0072] As an example, the first reference signal measurement threshold can be the RSRP threshold.

[0073] In some other embodiments, the first reference signal measurement threshold can be used to select a random access type.

[0074] In some embodiments, when the terminal device supports a 4-stage random access type and a 2-stage random access type simultaneously, the terminal device determines which random access type to use to initiate random access through the corresponding first reference signal measurement threshold.

[0075] For example, when the measurement result of the downlink reference signal is greater than the threshold value of the first reference signal measurement amount, a two-stage random connection type can be selected.

[0076] Therefore, by configuring a reference signal measurement threshold suitable for a reduced-capacity terminal, the reduced-capacity terminal can select a suitable random access type based on that threshold, which is advantageous for increasing the probability of a successful random access.

[0077] In some other embodiments, the first reference signal measurement threshold may be used to select a carrier used for random connection selection. The first reference signal measurement threshold may also be referred to as a Supplementary Uplink (SUL) carrier selection threshold, that is, the first reference signal measurement threshold may be used to determine whether a terminal device initiates a random connection on the corresponding SUL carrier.

[0078] For example, when the measurement result of the downlink reference signal is greater than the threshold value of the first reference signal measurement amount, the terminal device can select the SUL carrier, otherwise it can select the Normal Uplink (NU) carrier.

[0079] Therefore, by configuring a reference signal measurement threshold suitable for a reduced capability terminal, the terminal can select a suitable carrier based on the threshold to initiate random access, which is advantageous for increasing the probability of successful random access.

[0080] It should be understood that the application of the above reference signal measurement threshold is merely illustrative, and that the said reference signal measurement threshold may also be applied to other situations in which subsequent operations are performed based on the measurement results by performing measurements on the downlink reference signal, and that this application is not limited thereto.

[0081] FIG. 3 is an exemplary flowchart of another wireless communication method (300) provided by an embodiment of the present application. The method (300) can be executed by a terminal device in the communication system shown in FIG. 1, and as shown in FIG. 3, the method (300) may include some of the following contents.

[0082] S310, the terminal device determines a target reference signal measurement threshold used by the terminal device based on a reference signal measurement threshold corresponding to a second type terminal and the capability of a first type terminal, wherein the terminal device belongs to the first type terminal, the first type terminal includes a capability reduction terminal, and the second type terminal does not include a capability reduction terminal.

[0083] In the corresponding embodiment, it should be understood that the concepts of the first type terminal and the second type terminal may be referred to in the relevant description in the method (200) and are not further described herein.

[0084] In the corresponding embodiment, the network device may not configure a reference signal measurement threshold independent of the first type terminal, and the terminal device may determine a reference signal measurement threshold applied to the first type terminal based on a reference signal measurement threshold corresponding to the second type terminal.

[0085] In other words, the network device can configure only the reference signal measurement threshold corresponding to the second type terminal, and all reference signal measurement thresholds corresponding to other types of terminals can be determined by the reference signal measurement threshold corresponding to the second type terminal.

[0086] In some embodiments, the terminal device may determine a target reference signal measurement threshold used by the terminal device by combining the capabilities of the first type terminal with a reference signal measurement threshold corresponding to the second type terminal.

[0087] For example, if the capability of the first type terminal is lower than the capability of the second type terminal, the terminal device can determine that the reference signal measurement threshold corresponding to the first type terminal is lower than the reference signal measurement threshold corresponding to the second type terminal.

[0088] As an example, the result of adding one offset to the reference signal measurement threshold corresponding to the second type terminal is determined as the reference signal measurement threshold corresponding to the first type terminal, and said offset is negative.

[0089] Also, for example, if the capability of the first type terminal is higher than the capability of the second type terminal, the terminal device can determine that the reference signal measurement threshold corresponding to the first type terminal is higher than the reference signal measurement threshold corresponding to the second type terminal.

[0090] As an example, the result of adding one offset to the reference signal measurement threshold corresponding to the second type terminal is determined as the reference signal measurement threshold corresponding to the first type terminal, wherein the offset is an integer.

[0091] In one specific embodiment, the terminal device may determine a first adjustment amount by the capability of the first type terminal and the capability of the second type terminal, and furthermore, may determine a target reference signal measurement amount threshold by the reference signal measurement amount threshold corresponding to the second type terminal and the first adjustment amount.

[0092] In some embodiments, the reference signal measurement threshold corresponding to the second type terminal may be represented as the RSRP range (RSRP-Range). In some situations, the value range of the RSRP-Range is 0 to 127, and the actual RSRP threshold obtained after subtracting 156 dBm from the value is infinite, except when the value is 127.

[0094] For example, if the second type terminal supports a frequency band with a minimum number of receiving antennas of 2 and the first type terminal supports a frequency band with a number of receiving antennas of 1, under this situation, the first adjustment amount can be determined to be -3dBm.

[0095] Type 2 terminals are based on the actual RSRP threshold obtained by subtracting 156 dBm from the RSRP range value in Table 1. Type 1 terminals may be based on the actual RSRP threshold obtained by subtracting 3 dBm from the RSRP range value in Table 1 after subtracting 156 dBm.

[0096] For example, if the network device indicates a reference signal measurement threshold of 10 corresponding to a Type 2 terminal, the actual RSRP threshold calculated and obtained when spoken to the Type 2 terminal is -146 dBm. The RSRP range in the table above is [-146, -145) dBm. The actual RSRP threshold calculated and obtained when spoken to the Type 2 terminal is -149 dBm. The RSRP range in the table above is [-149, -148) dBm.

[0097] For example, if the second type terminal supports a frequency band with a minimum number of receiving antennas of 2 and the first type terminal supports a frequency band with a number of receiving antennas of 1, and the receiving antenna gain of the first type terminal has a loss of 3dB compared to the receiving antenna gain of the second type terminal, then under this situation, the first adjustment amount can be determined as -6dBm.

[0098] Type 2 terminals are based on the actual RSRP threshold obtained by subtracting 156 dBm from the RSRP range values ​​in Table 1. Type 1 terminals may be based on the actual RSRP threshold obtained by subtracting 156 dBm from the RSRP range values ​​in Table 1 and then subtracting 6 dBm.

[0099] For example, if the network device indicates a reference signal measurement threshold of 10 corresponding to a Type 2 terminal, the actual RSRP threshold obtained by calculation when spoken to the Type 2 terminal is -146 dBm. The RSRP range in the table above is [-146, -145) dBm. The actual RSRP threshold obtained by calculation when spoken to the Type 2 terminal is -152 dBm. The corresponding RSRP range in the table above is [-152, -151) dBm.

[0100] It should be understood that the method for determining the first adjustment amount above is merely an example, and that in other embodiments, the first adjustment amount may be set to a different value, and that the present application does not limit such values.

[0101] It should also be understood that in the embodiments of the present application, the method of determining a reference signal measurement threshold corresponding to the first type terminal by the capability of the first type terminal is merely an example, and in other embodiments, the terminal device may also determine a reference signal measurement corresponding thereto by a different algorithm, for example, there may be a specific offset between the reference signal measurement threshold corresponding to the first type terminal and the reference signal measurement threshold corresponding to the second type terminal, and said specific offset may be predefined, such as 3dB, or configured by a network device.

[0102] Accordingly, in the corresponding embodiment, it is not necessary to add a new reference signal measurement threshold, and the terminal device can reduce signal overhead by determining the target reference signal measurement threshold it uses based on the reference signal measurement threshold already configured by the network device by a preset algorithm, and can maintain backward compatibility with minimal modification of the conventional protocol.

[0103] In an embodiment of the present application, the first type terminal includes various sub-terminal types, and among the various sub-terminal types, each sub-terminal type corresponds to a specific capability, that is, the capabilities of each sub-terminal type are also different.

[0104] Optionally, in some embodiments, various sub-terminal types correspond to corresponding adjustment amounts.

[0105] 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, where the capability of the first sub-terminal type is higher than the capability of the second sub-terminal type.

[0106] The terminal device can determine the sub-terminal type to which it belongs based on its capabilities, and furthermore, can determine the target adjustment amount by combining the sub-terminal types to which it belongs.

[0107] In the corresponding embodiment, the application of the reference signal measurement threshold corresponding to the first type terminal determined by the terminal device may be described by referring to the relevant implementation in the method (200) and is not described further here for brevity.

[0108] In some embodiments, the reference signal measurement threshold corresponding to the first type terminal may be used for selecting a downlink reference signal.

[0109] In some other embodiments, the reference signal measurement threshold corresponding to the first type terminal may be used to select a random access type.

[0110] In another embodiment, the reference signal measurement threshold corresponding to the first type terminal may be used to select a carrier used for random connection initiation.

[0111] In summary, the above-described method allows a network device to configure a reference signal measurement threshold dedicated to a first-type terminal, or a terminal device to determine a reference signal measurement threshold corresponding to the first-type terminal by combining the capabilities of the first-type terminal with a reference signal measurement threshold corresponding to a second-type terminal, and furthermore, when the first-type terminal performs a reference signal selection based on the reference signal measurement threshold, it is advantageous to ensure a suitable reference signal selection, thereby ensuring subsequent data communication.
