Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to an information transmission method, apparatus, related equipment, storage medium, and computer program product. Background Technology

[0002] In related technologies, under Radio Resource Control (RRC) idle state (which can be expressed as IDLE) or inactive state (which can be expressed as Inactive), such as Figure 1 As shown, the terminal can perform measurements of the serving cell and neighboring cells based on the synchronization signal / physical broadcast channel block (SSB) using the main module (MR). This measurement mode can be called MR measurement. Alternatively, the terminal can also perform measurements of the serving cell based on the low-power synchronization signal (LP-SS) or the SSB signal using a low-power wake-up signal receiver (LP-WUR). This measurement mode can be called low-power (LR) measurement.

[0003] However, if the LR and MR measurements support different frequencies, the terminal may not know how to switch between MR and LR measurements. Summary of the Invention

This allows the terminal to determine how to perform LR measurement based on the measurement criteria, and also to determine whether to fall back from LR measurement to MR measurement based on the switching criteria. Thus, even when the LR and MR measurements support different frequency points, the terminal can still achieve fallback between LR and MR measurements.

[0117] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0118] Generally, LR measurements and MR measurements support the same frequency points; in other words, only when operating on the same frequency point can MR measurements offload the serving cell measurement behavior to LR measurements, and LR measurements can roll back the serving cell measurement behavior to MR measurements. The offloading and rollback criteria include at least the following:

[0119] 1. When the SSB signal quality is good (e.g., the SSB-reference received power (RSRP) is greater than the SSB threshold (ThresholdSSB), the terminal will stop the measurement of neighboring cells and offload the serving cell measurement from MR measurement to LR measurement.

[0120] 2. When the signal quality of the low-power synchronization signal (LP-SS) / secondary synchronization signal block (SSS) deteriorates (for example, LP-RSRP is less than the LP-SS threshold (ThresholdLP-SS), or LP-SSS-RSRP is less than ThresholdSSS), the terminal will backtrack the serving cell measurement from LR measurement to MR measurement and decide whether to enable neighbor cell measurement based on the signal conditions.

[0121] The above process requires that LR and MR measurements operate on the same frequency. MR measurements typically support multiple frequency points deployed by multiple operators. During or after network access, the terminal can select the frequency point with the best quality or the highest priority that meets the quality requirements for access or camping, based on the network deployment. However, to meet the above conditions, if LR measurements also support all the frequency points supported by MR measurements, it will significantly increase the cost of LR measurements on the terminal side. Furthermore, the network side will need to allocate resources for each frequency point to transmit LP-SS signals, thereby increasing network overhead.

[0122] To address the aforementioned issues, if LP-SS signals are transmitted at specific frequencies and LR measurements support measurements at those specific frequencies, the overhead on the network and terminal sides will be significantly reduced. In other words, LR can determine the cell quality at the serving frequency fB by measuring a specific frequency fA.

[0123] However, when MR measurement is accessed and camped on a non-LR specific frequency point, since LR measurement does not support measurement on that non-LR specific frequency point, according to the relevant offload and rollback criteria, the terminal cannot offload MR measurement to LR measurement, nor can it determine whether it can roll back to MR measurement based on the LR measurement results.

[0124] Based on this, in various embodiments of this application, the network side configures the terminal with measurement criteria for LR measurement and fallback criteria for MR measurement, enabling the terminal to make fallback decisions during LR measurement. Thus, even in scenarios where the frequency point of the LP-SS issued by the network differs from the current access frequency point of the terminal, or where the terminal's access frequency point differs from the frequency point supported by LR measurement, the terminal can still switch between LR and MR measurements.

[0125] This application provides an information transmission method applied to a terminal, such as... Figure 2 As shown, the method includes:

[0126] Step 201: Receive one or more first pieces of information sent by the network device, wherein the one or more first pieces of information characterize measurement criteria and / or switching criteria associated with a first measurement mode and a second measurement mode;

[0127] Step 202: Utilize the one or more pieces of first information to perform the measurement of the first measurement mode.

[0128] In practical applications, the terminal can be referred to as User Equipment (UE) or simply as a user, etc. This application embodiment does not limit this, as long as its function is implemented. The network device can specifically be a base station; in a co-location scenario, base stations of different frequency bands can be deployed in the same area, resulting in overlapping coverage areas; in a non-co-location scenario, such as... Figure 3 As shown, base stations of different frequency bands can be deployed in different areas so that the corresponding coverage areas do not overlap. For example, base stations of 700M, 2.6G and 4.9G frequency bands can be deployed in different areas.

[0129] In addition, the first measurement mode can be understood as LR measurement. Specifically, in the first measurement mode, the terminal can perform LP-RSRP and / or LP-reference signal reception quality (RSRQ) measurement; the second measurement mode can be understood as MR measurement. In the second measurement mode, the terminal can perform SS-RSRP and / or SS-RSRQ measurement; wherein, the measurement power in the first measurement mode is lower than the measurement power in the second measurement mode.

[0130] In practical applications, the terminal can receive one or more of the first information through relevant system information; wherein each first information may include one or more of the following (or at least one):

[0131] A first frequency point, the first frequency point supports the transmission of a first reference signal, the first reference signal being used for measurement in the first measurement mode;

[0132] The second information includes the first threshold corresponding to the first frequency point;

[0133] The third information includes a second threshold corresponding to the service frequency point;

[0134] The fourth information represents the offset between the first threshold and the second threshold;

[0135] The fifth information represents the first measurement priority of the first measurement mode corresponding to the first frequency point.

[0136] In practical applications, the first frequency point can be understood as the frequency point of the first reference signal transmitted by the network device (also called the transmission frequency point). The first reference signal may include LP-SS and / or SSB, and correspondingly, the first frequency point may include the ARFCN-ValueNR corresponding to the transmission frequency point of LP-SS or SSB; different first information may correspond to different first frequency points. The first threshold can be understood as the reference signal quality threshold of the first reference signal. For example, when the first reference signal is LP-SS, the first threshold may include the RSRP of LP-SS (which can be expressed as LP-SS-RSRP) or the RSRQ of LP-SS (which can be expressed as LP-SS-RSRQ). Similarly, when the first reference signal is SSB, the first threshold may include the RSRP of SSB (which can be expressed as LP-SSS-RSRP) or the RSRQ of SSB (which can be expressed as LP-SSS-RSRQ). The second threshold can be understood as the reference signal quality threshold (also called the common threshold) corresponding to the cell serving frequency point. The fourth information can be understood as the offset of the first threshold relative to the second threshold. For example, when the first reference signal is LP-SS, the fourth information can be represented as LP-SS-RSRP-Offset or LP-SS-RSRQ-Offset. Or, when the first reference signal is SSB, the fourth information can be represented as LP-SSS-RSRP-Offset or LP-SSS-RSRQ-Offset.

[0137] In addition, the fifth piece of information can be understood as priority information, which indicates the priority of the first frequency point for performing the measurement in the first measurement mode.

[0138] It should be noted that in a co-location scenario, the coverage areas of network devices may overlap, resulting in the terminal being approximately equidistant from network devices operating on different frequency bands. Therefore, the measurement results of the first measurement mode and the second measurement mode have a linear relationship only when the frequency points differ. Consequently, the network device can configure and send the first information to the terminal based on this linear relationship, enabling the terminal to perform measurements in the first measurement mode and determine whether to switch to the second measurement mode during the measurement process.

[0139] In practical applications, for one or more pieces of first information, the terminal can select the first information to implement the measurement of the first measurement mode based on the receiving capability of the first measurement mode.

[0140] Specifically, in one embodiment, the implementation of step 202 may include:

[0141] When one or more pieces of first information contain the first frequency point, the sixth information is used to select the first information that satisfies the first condition from the one or more pieces of first information. The first condition indicates that the terminal can support the measurement of the first measurement mode of the first frequency point, and the sixth information indicates the receiving capability of the terminal.

[0142] The first measurement mode is used to perform the measurement using the selected first information.

[0143] The sixth piece of information represents the terminal's reception capability (which can be referred to as LR reception capability) in the first measurement mode.

[0144] In practical applications, by using the sixth information, the terminal can determine the measurement of the first measurement mode corresponding to the first frequency point it supports, and then select the first information that satisfies the first condition.

[0145] Here, after selecting the first information that satisfies the first condition, the terminal can further select the first information in different ways based on whether the first information contains the fifth information; wherein, if the first information contains the fifth information, the first information can be selected through the fifth information.

[0146] Specifically, in one embodiment, the step of using the selected first information to perform the measurement of the first measurement mode includes:

[0147] If one or more of the selected first information contains the fifth information, the first information with the highest measurement priority is determined from the selected first information;

[0148] The first measurement mode is performed using the first information with the highest measurement priority.

[0149] In practical applications, at least one of the selected first information contains the fifth information. The terminal can set the first measurement priority corresponding to the first information that does not contain the fifth information to 0 (i.e., the lowest priority). Then, it selects the first information with the highest first measurement priority from the selected first information to perform the measurement in the first measurement mode and determine whether to switch to the second measurement mode during the measurement process.

[0150] It should be noted that, during the process of determining whether to switch to the second measurement mode, if the first information includes the first threshold, the terminal can determine whether to switch from the first measurement mode to the second measurement mode based on the measurement result of the first measurement mode and the first threshold; if the first information includes the second threshold and the offset between the first threshold and the second threshold, the terminal can calculate the first threshold, and then determine whether to switch from the first measurement mode to the second measurement mode based on the measurement result of the first measurement mode and the first threshold; wherein, if the measurement result of the first measurement mode is less than the first threshold, the measurement of switching from the first measurement mode to the second measurement mode is determined.

[0151] For example, such as Figure 4 As shown, assuming the terminal initially accesses and camps on cell 1 in the 4.9GHz band, and the network device transmits SSB signals in the 2.6GHz band and LP-SS signals in the 700MHz band, and the terminal supports LP-SS in the 700MHz band and SSB signals in the 2.6GHz band, the network device can send two first messages to the terminal via system information: First Message 1 and First Message 2. First Message 1 contains the first frequency point fA, the first threshold LP-SS-RSRP = 3dB, and the first measurement priority 2. First Message 2 contains the first frequency point fB1, the first threshold LP-SS-RSRP = 0dB, and the first measurement priority 1. After receiving First Message 1 and First Message 2, the terminal selects First Message 1, which has the highest first measurement priority, to perform the measurement in the first measurement mode based on the reception capability and the first measurement priority in the first measurement mode. In other words, when the measurement result in the second measurement mode meets the offloading criteria (e.g., the RSRP of the SSB is greater than a preset threshold or the change in the RSRP of the SSB is less than a preset threshold), the terminal can start the measurement in the first measurement mode and measure the LP-SS at the fA frequency point; during the measurement process, when the RSRP of the LP-SS is less than 3dB, the terminal can switch from the first measurement mode to the second measurement mode.

[0152] In practical applications, since the highest first measurement priority may correspond to multiple first information, the terminal can select the first information based on the relationship between the service frequency point and the first frequency point.

[0153] Specifically, in one embodiment, determining the first information with the highest measurement priority from the selected first information includes:

[0154] When the first information with the highest measurement priority contains multiple pieces of first information, the first information that satisfies the second condition is determined from the first information with the highest measurement priority. The second condition indicates that the difference between the first frequency point and the service frequency point is minimized.

[0155] The smaller the difference between the first frequency point and the serving frequency point, the more similar the coverage areas of the cells corresponding to the two frequency points are.

[0156] In practical applications, when the first information with the highest measurement priority contains multiple pieces of first information (e.g., 3 pieces), the terminal can select the first information corresponding to the first frequency point with the smallest difference from the service frequency point (i.e., the first information that satisfies the second condition) from the multiple pieces of first information, so as to perform the measurement of the first measurement mode through the selected first information.

[0157] In practical applications, after selecting the first information that satisfies the first condition, if none of the first information contains the fifth information, the terminal can select the first information based on the relationship between the service frequency point and the first frequency point.

[0158] Specifically, in one embodiment, the step of using the selected first information to perform the measurement of the first measurement mode includes:

[0159] If the selected first information does not include the fifth information, the first information that satisfies the second condition is determined from the selected first information, whereby the second condition indicates that the difference between the first frequency point and the service frequency point is minimized.

[0160] The first measurement mode is measured using the first information that satisfies the second condition.

[0161] For example, such as Figure 4As shown, assuming the terminal initially accesses and camps on cell 1 in the 4.9GHz band, and the network device will distribute LP-SS in cells in the 2.6GHz and 700MHz bands, if the terminal supports LP-SS in the 700MHz band, the network device can send two first messages to the terminal via system information: first message 3 and first message 4. First message 3 contains the first frequency point fA and the first threshold LP-SS-RSRP = 3dB. First message 4 contains the first frequency point fB1 and the first threshold LP-SS-RSRP = 0dB. The terminal selects the first message 3 corresponding to fA for measurement in the first measurement mode based on its reception capability in the first measurement mode. In other words, if the measurement result of the terminal in the second measurement mode meets the offloading criterion, the terminal can start the measurement in the first measurement mode and measure the LP-SS at frequency point fA; if the RSRP of the LP-SS is less than 3dB, the terminal can determine that it needs to switch from the first measurement mode to the second measurement mode.

[0162] In practical applications, in scenarios where network devices are not co-located, the coverage areas of network devices do not overlap, resulting in different distances between the terminal and network devices on different frequency bands. Therefore, when both the frequency and distance are different, the measurement results corresponding to the first measurement mode and the measurement results corresponding to the second measurement mode do not have a linear relationship.

[0163] To address the aforementioned issues, the network device can configure selection criteria for cell reselection for the terminal, enabling the terminal to prioritize reselecting to a frequency point supported by both the first and second measurement modes when initiating cell reselection. This allows for switching between the first and second measurement modes.

[0164] Based on this, in one embodiment, the method may further include:

[0165] Receive the seventh information sent by the network device, the seventh information representing the selection criteria for cell reselection;

[0166] Using the seventh piece of information, cell reselection is performed.

[0167] In practical applications, the terminal can receive the seventh information through relevant system information; wherein, in one embodiment, the seventh information may include one or more of the following:

[0168] One or more second frequency points, the one or more second frequency points supporting the transmission of a first reference signal, the first reference signal being used for measurement in the first measurement mode;

[0169] One or more third frequency points, wherein the one or more third frequency points do not support the transmission of a second reference signal, the second reference signal being used for measurement in the first measurement mode.

[0170] In practical applications, the second frequency point can be understood as the frequency point at which the network device transmits the first reference signal; the third frequency point can be understood as the frequency point at which the network device transmits the second reference signal, and the second reference signal may include LP-SS.

[0171] In practical applications, the terminal can select a second frequency point to achieve cell reselection based on the receiving capability in the first measurement mode.

[0172] Specifically, in one embodiment, the cell reselection using the seventh information includes:

[0173] If the seventh information includes one or more second frequency points, the sixth information is used to select a second frequency point from the one or more second frequency points that satisfies a third condition. The third condition indicates that the terminal can support the measurement of the first measurement mode of the second frequency point, and the sixth information indicates the receiving capability of the terminal.

[0174] Using the selected second frequency point, the eighth information is adjusted, wherein the eighth information represents the second measurement priority of the first measurement mode corresponding to the one or more second frequency points and the third measurement priority of the first measurement mode corresponding to the one or more third frequency points;

[0175] The adjusted eighth information is used to reselect the cell.

[0176] Specifically, the eighth piece of information can be obtained from relevant system information. This application embodiment does not limit the method of obtaining the eighth piece of information.

[0177] Here, using the sixth information, the terminal can determine the second frequency point of the measurement of the first measurement mode it supports (which can be simply referred to as the second frequency point supported by the terminal) and the second frequency point of the measurement of the first measurement mode it does not support (which can be simply referred to as the second frequency point not supported by the terminal), and then select the second frequency point that satisfies the third condition.

[0178] In practical applications, after selecting a second frequency point that meets the third condition, the terminal can adjust the priority of the second and third frequency points that it does not support, based on the selected second frequency point, so that the terminal can preferentially select a frequency point that is supported by both the first and second measurement modes.

[0179] Specifically, in one embodiment, adjusting the eighth information using the selected second frequency point includes:

[0180] Using the eighth information, determine the highest second measurement priority of the selected second frequency point;

[0181] If the third measurement priority of one or more third frequency points is greater than the highest second measurement priority, the third measurement priority of the one or more third frequency points shall be adjusted using the highest second measurement priority.

[0182] In practical applications, the eighth information is used to determine the highest second measurement priority and the third measurement priority of each third frequency point. If the third measurement priority of one or more third frequency points is greater than the highest second measurement priority, the terminal can adjust the third measurement priority of one or more third frequency points to the highest second measurement priority.

[0183] Specifically, in one embodiment, adjusting the eighth information using the selected second frequency point includes:

[0184] Using the eighth information, determine the highest second measurement priority of the selected second frequency point;

[0185] If the second measurement priority of any second frequency point other than the selected second frequency point is greater than the highest second measurement priority, the second measurement priority of the other second frequency points shall be adjusted using the highest second measurement priority.

[0186] The other second frequency points can be understood as second frequency points that the terminal does not support.

[0187] In practical applications, the eighth information is used to determine the highest second measurement priority and the second measurement priority of the other second frequency points respectively; if the second measurement priority of the other second frequency points is greater than the highest second measurement priority, the terminal can adjust the second measurement priority of the other second frequency points to the highest second measurement priority.

[0188] Next, the terminal can use the adjusted second measurement priority and / or third measurement priority to perform cell reselection and determine the selection criteria.

[0189] For example, such as Figure 5As shown, assuming the terminal initially accesses and camps on cell 1 in the 4.9GHz band, and the network device issues SSBs in cells in the 2.6GHz band and LP-SSs in cells in the 700MHz band, if the terminal supports LP-SS in the 700MHz band, the network device can send two seventh messages to the terminal via system information. These seventh messages contain two second frequency points and one third frequency point: second frequency point 1 (which can be represented as fA, with a corresponding second measurement priority of 3), second frequency point 2 (which can be represented as fB1, with a corresponding second measurement priority of 4), and third frequency point (which can be represented as fB2, with a corresponding third measurement priority of 7). Upon receiving the seventh messages, the terminal can select its supported second frequency point 1, and based on the second measurement priority of second frequency point 1, adjust the third measurement priority of the third frequency point to 3 and the second measurement priority of second frequency point 2 to 3. Then, the terminal performs cell reselection based on the adjusted measurement priorities. Thus, in a cell reselection scenario, the terminal can preferentially select the cell corresponding to second frequency point 1.

[0190] Accordingly, embodiments of this application also provide an information transmission method, applied to network devices, such as... Figure 6 As shown, it includes:

[0191] Step 601: Send one or more first pieces of information to the terminal, wherein the one or more first pieces of information characterize measurement criteria and / or switching criteria associated with the first measurement mode and the second measurement mode, and the one or more first pieces of information are used for measurement in the first measurement mode.

[0192] In practical applications, in response to the one or more first pieces of information, the network device can configure the first threshold and the fourth information for the terminal based on its own transmission environment and the difference between the first frequency point and the service frequency point (also known as the frequency difference).

[0193] In practical applications, in scenarios where the network is not co-located, the network device can also send selection criteria for cell reselection to the terminal.

[0194] Based on this, in one embodiment, the method may further include:

[0195] Step 602: Send the seventh information to the terminal, the seventh information representing the selection criteria for cell reselection.

[0196] Accordingly, embodiments of this application also provide an information transmission method, applied to a terminal, such as... Figure 7 As shown, it includes:

[0197] Step 701: Receive the seventh information sent by the network device, wherein the seventh information represents the selection criteria for cell reselection;

[0198] Step 702: Use the seventh information to perform cell reselection.

[0199] In one embodiment, the specific implementation of step 702 may include:

[0200] If the seventh information includes one or more second frequency points, the sixth information is used to select a second frequency point from the one or more second frequency points that satisfies a third condition. The third condition indicates that the terminal can support the measurement of the first measurement mode of the second frequency point, and the sixth information indicates the receiving capability of the terminal.

[0201] Using the selected second frequency point, the eighth information is adjusted, wherein the eighth information represents the second measurement priority of the first measurement mode corresponding to the one or more second frequency points and the third measurement priority of the first measurement mode corresponding to the one or more third frequency points;

[0202] The adjusted eighth information is used to reselect the cell.

[0203] In one embodiment, the cell reselection using the seventh information includes:

[0204] If the seventh information includes one or more second frequency points, the sixth information is used to select a second frequency point from the one or more second frequency points that satisfies a third condition. The third condition indicates that the terminal can support the measurement of the first measurement mode of the second frequency point, and the sixth information indicates the receiving capability of the terminal.

[0205] Using the selected second frequency point, the eighth information is adjusted, wherein the eighth information represents the second measurement priority of the first measurement mode corresponding to the one or more second frequency points and the third measurement priority of the first measurement mode corresponding to the one or more third frequency points;

[0206] The adjusted eighth information is used to reselect the cell.

[0207] In one embodiment, adjusting the eighth information using the selected second frequency point includes:

[0208] Using the eighth information, determine the highest second measurement priority of the selected second frequency point;

[0209] If the second measurement priority of any second frequency point other than the selected second frequency point is greater than the highest second measurement priority, the second measurement priority of the other second frequency points shall be adjusted using the highest second measurement priority.

[0210] It should be noted that the specific processing procedure of step 702 has been described in detail above and will not be repeated here.

[0211] Accordingly, embodiments of this application also provide an information transmission method applied to a network device, including:

[0212] A seventh message is sent to the terminal, the seventh message representing the selection criteria for cell reselection.

[0213] The information transmission method provided in this application involves a terminal receiving one or more first pieces of information sent by a network device. These one or more first pieces of information represent measurement criteria and / or switching criteria associated with a first measurement mode and a second measurement mode. The terminal then uses these one or more first pieces of information to perform measurements in the first measurement mode. The technical solution provided in this application configures measurement criteria and switching criteria on the network side for the terminal to fall back from LR (i.e., the first measurement mode) measurements to MR measurements (i.e., the second measurement mode), thus associating MR measurements with LR measurements. This allows the terminal to determine how to perform LR measurements based on the measurement criteria, and also to determine whether to fall back from LR measurements to MR measurements based on the switching criteria. Therefore, even when the LR and MR measurements support different frequency points, the terminal can still achieve fallback between LR and MR measurements.

[0214] In addition, the terminal receives a seventh piece of information sent by the network device, which represents the selection criteria for cell reselection; and performs cell reselection using the seventh piece of information. The technical solution provided in this application configures selection criteria for cell reselection on the network side, enabling the terminal to prioritize cells corresponding to frequency points supported by both MR and LR measurements during the subsequent cell reselection process, thereby achieving offloading and backoff between LR and MR measurements.
