Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to an information updating method, apparatus, user equipment, base station, and storage medium. Background Technology

[0002] In satellite communication systems, cell-specific offset and UE-specific offset are typically introduced to compensate for transmission delay.

[0003] In related technologies, the cell-specific offset value is updated as the satellite moves. Therefore, the base station usually indicates the updated cell-specific offset value to the UE by sending updated system information to the UE.

[0004] However, in related technologies, the distances between various UEs and the base station within the same cell differ, resulting in different reception times for the updated system information sent by the base station. In other words, each UE obtains the updated cell-specific offset value at different times. This causes the base station to enter an ambiguity period. During this period, when the base station communicates with different UEs, the cell-specific offset values ​​used by each UE are different (i.e., the base station is unsure which cell-specific offset value each UE is using), which affects communication reliability. Summary of the Invention

[0005] The information updating method, apparatus, user equipment, base station, and storage medium disclosed herein are intended to address the technical problem that information updating methods in related technologies can easily affect communication performance.

[0007] Receive the updated cell-specific offset value sent by the base station;

[0008] The system receives configuration information sent by the base station, which indicates a time offset value and / or a time window. The time offset value indicates the delay time for the updated cell-specific offset to take effect, and the time window indicates the invalid time of the updated cell-specific offset.

[0009] The updated cell-specific offset is used based on the time offset value and / or time window.

[0010] The information updating method proposed in another embodiment of this disclosure, applied to a base station supporting satellite communication, includes:

[0011] Determine a time offset value and / or a time window, wherein the time offset value is used to indicate the delayed effective time of the updated cell-specific offset, and the time window is used to indicate the invalid time of the updated cell-specific offset;

[0012] Send configuration information to the UE to indicate the time offset value and / or time window;

[0020] The transmitting module is used to send configuration information to the UE to indicate the time offset value and / or time window;

[0021] The sending module is also used to send an updated cell-specific offset to the UE.

[0025] The interface circuit is used to receive code instructions and transmit them to the processor;

[0026] The processor is configured to run the code instructions to perform the method as proposed in one aspect of the embodiments.

[0031] Another aspect of this disclosure provides a computer-readable storage medium for storing instructions that, when executed, cause the method as described in another aspect of this disclosure to be implemented.

[0057] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with those of this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the embodiments of this disclosure as detailed in the appended claims.

[0059] It should be understood that although the terms first, second, third, etc., may be used to describe various information in embodiments of this disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, first information may also be referred to as second information without departing from the scope of embodiments of this disclosure, and similarly, second information may also be referred to as first information.

[0060] Figure 1a This is a schematic diagram illustrating the communication between a UE and a base station in an information update method of related technology provided in an embodiment of this disclosure, as shown below. Figure 1a As shown, the near-end UE (User Equipment) closer to the base station within the cell receives the updated system information sent by the base station first, while the far-end UE receives the updated system information later. Because each UE receives the updated system information at different times, an ambiguity period exists for the base station. During this ambiguity period, the near-end UE has already obtained the updated cell-specific offset value and uses it to communicate with the base station, while the far-end UE has not yet obtained the updated cell-specific offset value and uses the old cell-specific offset value to communicate with the base station, leading to low communication reliability. Based on this, the present invention proposes an information updating method, apparatus, user equipment, base station, and storage medium to solve the technical problem of low communication reliability caused by information updating methods in related technologies.

[0061] The following is a detailed description of an information updating method, apparatus, user equipment, base station, and storage medium provided in one embodiment of the present disclosure, with reference to the accompanying drawings.

[0062] Figure 1b This is a flowchart illustrating an information update method provided in one embodiment of the present disclosure. The method is executed by a UE that supports satellite communication. Figure 1b As shown, the information update method may include the following steps:

[0063] Step 101: Receive the updated cell-specific offset value sent by the base station.

[0064] In one embodiment of this disclosure, the base station may be a satellite communication-enabled base station, and the UE may be a device that provides voice and / or data connectivity to the user. The terminal device may communicate with one or more core networks via a RAN (Radio Access Network). The UE may be an IoT terminal, such as a sensor device, a mobile phone (or "cellular" phone), or a computer with an IoT terminal, for example, a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile terminal, remote station, access point, remote terminal, access terminal, user terminal, or user agent. Alternatively, the UE may also be a device of an unmanned aerial vehicle. Alternatively, the UE may also be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless terminal connected to an external vehicle computer. Alternatively, the UE can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0065] In one embodiment of this disclosure, the base station sends a cell-specific offset value to the UE via system information. Specifically, the cell-specific offset value can be included in the system information. It should be noted that after the base station sends a cell-specific offset value to the UE via system information, if the satellite in the satellite communication scenario where the base station is located moves relative to the cell, the base station needs to update the cell-specific offset value and send the updated cell-specific offset value to the UE via the updated system information.

[0066] Based on this, the base station can determine whether to instruct the UE to update the cell-specific offset value based on the satellite communication scenario in which the UE and the base station are located.

[0067] Specifically, in one embodiment of this disclosure, the base station determines the satellite communication scenario of the base station and the UE based on ephemeris information. If the base station determines that the satellite communication scenario of the UE and the base station is a GEO (Geostationary Earth Orbit) scenario, it means that the satellite is stationary relative to the ground. In this case, the base station does not need to instruct the UE to update the cell-specific offset value; that is, the base station does not send the updated cell-specific offset value to the UE. When the base station determines that the satellite communication scenario of the UE and the base station is an NGSO (Non-Geostationary Orbit) scenario, it means that the satellite will move relative to the ground. In this case, if the satellite moves relative to the ground, the base station needs to send the updated cell-specific offset value to the UE using updated system information.

[0068] Step 102: Receive configuration information sent by the base station to indicate the time offset value and / or time window.

[0069] In one embodiment of this disclosure, the time offset value can be used to indicate the delayed effective time of the updated cell-specific offset value, and the time window can be used to indicate the invalid time of the updated cell-specific offset value. A detailed description of the time offset value and the time window will be provided in subsequent embodiments.

[0070] Furthermore, in one embodiment of this disclosure, the method for the UE to receive configuration information sent by the base station indicating a time offset value and / or a time window may include at least one of the following:

[0071] Receive configuration information sent by the base station via user equipment-specific signaling;

[0072] Receive configuration information sent by the base station via common signaling.

[0073] Step 103: Use the updated cell-specific offset value based on the time offset value and / or time window.

[0074] A detailed description of step 103 will be provided in subsequent embodiments.

[0075] Furthermore, it should be noted that in one embodiment of this disclosure, the execution order of steps 101-103 is merely one possible execution order for this example, and is not a fixed order. For example, in one embodiment of this disclosure, there is no fixed order between steps 101 and 102. Step 101 can be executed first, followed by step 102, or step 102 can be executed first, followed by step 101.

[0076] In summary, in the information update method provided in one embodiment of this disclosure, the UE receives configuration information sent by the base station indicating a time offset value and / or a time window. The time offset value indicates the delayed effective time of the updated cell-specific offset value, and the time window indicates the invalidation time of the updated cell-specific offset value. When the UE receives the updated cell-specific offset value sent by the base station, it uses the updated cell-specific offset value based on the time offset value and / or the time window. Therefore, in this embodiment of the disclosure, the effective time of the updated cell-specific offset value is specifically determined through the time offset value and / or the time window to ensure that when each UE in the cell sends uplink information to the base station based on the updated cell-specific offset value, the base station has the same understanding of the cell-specific offset value used by different UEs, thus ensuring communication reliability.

[0077] Figure 2a This is a flowchart illustrating an information update method provided in one embodiment of the present disclosure. The method is executed by a UE that supports satellite communication. Figure 2a As shown, the information update method may include the following steps:

[0078] Step 201: Receive the updated cell-specific offset value sent by the base station.

[0079] The relevant description of step 201 can be found in the above embodiments, and will not be repeated here.

[0080] Step 202: Receive configuration information sent by the base station to indicate the time offset value.

[0081] In one embodiment of this disclosure, the time offset value can be used to indicate the delayed effective time of the updated cell-specific offset value.

[0082] In one embodiment of this disclosure, the time offset value can be determined by the base station based on the RTT (Round Trip Time) of signal transmission within its coverage area. Furthermore, in one embodiment of this disclosure, the time offset value may differ for different UEs within the cell. Also, in one embodiment of this disclosure, the magnitude of the time offset value may be inversely proportional to the distance between the UE and the base station. For example, the farther a UE is from the base station, the smaller its time offset value; conversely, the closer a UE is to the base station, the larger its time offset value.

[0083] Furthermore, in one embodiment of this disclosure, the time offset value can be a fixed value. In another embodiment of this disclosure, the time offset value can be a configurable value.

[0084] Step 203: Use the updated cell-specific offset value based on the time offset value.

[0085] In one embodiment of this disclosure, the method of using an updated cell-specific offset value based on a time offset value may include: after receiving the updated cell-specific offset value, communicating with the base station using the cell-specific offset value before the update within the time offset value, and / or, after delaying the time offset value, communicating with the base station using the updated cell-specific offset value.

[0086] It should be noted that, in one embodiment of this disclosure, the time offset value should satisfy the following condition: the time offset value enables the base station to have the same understanding of the cell-specific offset value used by each UE within the cell. That is, when each UE within the cell communicates with the base station using the updated cell-specific offset value after a corresponding time offset value delay, there is no ambiguity period for the base station. This ambiguity period is a period during which different UEs within the cell receive the updated cell-specific offset value at different times due to differences in distance between the UEs and the base station. During this period, different UEs within the cell use different cell-specific offset values ​​when communicating with the base station. For example, some UEs within the cell (such as near-end UEs that are closer to the base station) communicate with the base station using the updated cell-specific offset value, while other UEs within the cell (such as far-end UEs that are closer to the base station) communicate with the base station using the cell-specific offset value before the update.

[0087] Example, Figure 2b This is a schematic diagram illustrating the communication between a UE and a base station during an information update method provided in an embodiment of this disclosure, as shown below. Figure 2b As shown, the base station determines the updated system information, which includes the updated cell-specific offset value. The base station then broadcasts this updated system information to each UE within the cell. Near-end UEs receive the updated system information first, followed by far-end UEs. After receiving the updated system information, each UE parses it to obtain the updated cell-specific offset value. However, after obtaining the updated cell-specific offset value, each UE does not immediately communicate with the base station based on it. Instead, it first communicates with the base station based on the cell-specific offset value before the update. After a delay of the corresponding time offset value, it then communicates with the base station based on the updated cell-specific offset value. This ensures that the base station has the same understanding of the cell-specific offset value used by each UE within the cell, avoiding ambiguity periods and ensuring communication reliability.

[0088] In summary, in the information update method provided in one embodiment of this disclosure, the UE receives configuration information sent by the base station indicating a time offset value and / or a time window. The time offset value indicates the delayed effective time of the updated cell-specific offset value, and the time window indicates the invalidation time of the updated cell-specific offset value. When the UE receives the updated cell-specific offset value sent by the base station, it uses the updated cell-specific offset value based on the time offset value and / or the time window. Therefore, in this embodiment of the disclosure, the effective time of the updated cell-specific offset value is specifically determined through the time offset value and / or the time window to ensure that when each UE in the cell sends uplink information to the base station based on the updated cell-specific offset value, the base station has the same understanding of the cell-specific offset value used by different UEs, thus ensuring communication reliability.

[0089] Figure 3 This is a flowchart illustrating an information update method provided in one embodiment of the present disclosure. The method is executed by a UE that supports satellite communication. Figure 3 As shown, the information update method may include the following steps:

[0090] Step 301: Receive the updated cell-specific offset value sent by the base station.

[0091] For details regarding step 301, please refer to the description in the above embodiments; the embodiments disclosed herein will not be repeated here.

[0092] Step 302: Receive configuration information sent by the base station to indicate the time window.

[0093] In one embodiment of this disclosure, the time window can be used to indicate the invalid time of the updated cell-specific offset value. Step 303: Use the updated cell-specific offset value based on the time offset value.

[0094] In one embodiment of this disclosure, the method of using an updated cell-specific offset value based on a time offset value may include: communicating with the base station using the UE-specific offset value within the time window; communicating with the base station using the updated cell-specific offset value after the time window; and communicating using the cell-specific offset value before the time window.

[0095] Furthermore, the aforementioned method of "communicating with the base station using a UE-specific offset value within the time window" may include at least one of the following:

[0096] Method 1: Within this time window, the UE performs communication operations that require the use of a cell-specific offset value based on the UE-specific offset value;

[0097] Method 2: During this time window, the UE does not perform communication operations that require the use of cell-specific offset.

[0098] Furthermore, in one embodiment of this disclosure, the aforementioned communication operation may specifically be an uplink operation and / or a downlink operation between the UE and the base station.

[0099] It should be noted that, in one embodiment of this disclosure, the time window should satisfy the following condition: the time window ensures that the base station has the same understanding of the cell-specific offset values ​​used by each UE within the cell. That is, when each UE within the cell communicates with the base station using the updated cell-specific offset value after the time window is delayed, there is no ambiguity period for the base station. This ambiguity period is a period during which different UEs within the cell use different cell-specific offset values ​​when communicating with the base station due to the difference in distance between each UE and the base station. For example, some UEs within the cell (such as near-end UEs that are closer to the base station) communicate with the base station using the updated cell-specific offset value, while other UEs within the cell (such as far-end UEs that are closer to the base station) communicate with the base station using the cell-specific offset value before the update.

[0100] Furthermore, it should be understood that a specific offset value for the UE can be determined by means of a protocol, by means of signaling, or by other means, and this disclosure does not impose any restrictions on this.

[0101] In summary, in the information update method provided in one embodiment of this disclosure, the UE receives configuration information sent by the base station indicating a time offset value and / or a time window. The time offset value indicates the delayed effective time of the updated cell-specific offset value, and the time window indicates the invalidation time of the updated cell-specific offset value. When the UE receives the updated cell-specific offset value sent by the base station, it uses the updated cell-specific offset value based on the time offset value and / or the time window. Therefore, in this embodiment of the disclosure, the effective time of the updated cell-specific offset value is specifically determined through the time offset value and / or the time window to ensure that when each UE in the cell sends uplink information to the base station based on the updated cell-specific offset value, the base station has the same understanding of the cell-specific offset value used by different UEs, thus ensuring communication reliability.

[0103] Step 401a: Receive configuration information sent by the base station via UE-specific signaling to indicate the time offset value.

In summary, in the information update method provided in one embodiment of this disclosure, the UE receives configuration information sent by the base station indicating a time offset value, wherein the time offset value indicates the delayed effective time of the updated cell-specific offset value. When the UE receives the updated cell-specific offset value sent by the base station, it uses the updated cell-specific offset value based on the time offset value. Therefore, in this embodiment of the disclosure, the effective time of the updated cell-specific offset value is specifically determined by the time offset value to ensure that when each UE in the cell sends uplink information to the base station based on the updated cell-specific offset value, the base station has the same understanding of the cell-specific offset value used by different UEs, thus ensuring communication reliability.

[0106] Step 401b: Receive configuration information sent by the base station via common signaling to indicate the time offset value.

[0107] For details regarding step 401b, please refer to the description in the above embodiments.

[0108] In summary, in the information update method provided in one embodiment of this disclosure, the UE receives configuration information sent by the base station indicating a time offset value, wherein the time offset value indicates the delayed effective time of the updated cell-specific offset value. When the UE receives the updated cell-specific offset value sent by the base station, it uses the updated cell-specific offset value based on the time offset value. Therefore, in this embodiment of the disclosure, the effective time of the updated cell-specific offset value is specifically determined by the time offset value to ensure that when each UE in the cell sends uplink information to the base station based on the updated cell-specific offset value, the base station has the same understanding of the cell-specific offset value used by different UEs, thus ensuring communication reliability.

[0109] Figure 5 This is a flowchart illustrating an information update method provided in one embodiment of the present disclosure. The method is executed by a UE that supports satellite communication. Figure 5 As shown, the information update method may include the following steps:

[0110] Step 501: In response to receiving configuration information indicating a time offset value, after receiving the updated cell-specific offset value, communicate with the base station using the cell-specific offset value before the update within the time offset value, and / or, after delaying the time offset value, communicate with the base station using the updated cell-specific offset value.

[0111] For details regarding step 501, please refer to the description in the above embodiments.

[0112] In summary, in the information update method provided in one embodiment of this disclosure, the UE receives configuration information sent by the base station indicating a time offset value, wherein the time offset value indicates the delayed effective time of the updated cell-specific offset value. When the UE receives the updated cell-specific offset value sent by the base station, it uses the updated cell-specific offset value based on the time offset value. Therefore, in this embodiment of the disclosure, the effective time of the updated cell-specific offset value is specifically determined by the time offset value to ensure that when each UE in the cell sends uplink information to the base station based on the updated cell-specific offset value, the base station has the same understanding of the cell-specific offset value used by different UEs, thus ensuring communication reliability.

[0114] Step 601a: Receive configuration information sent by the base station via UE-specific signaling to indicate the time window.

[0115] For details regarding step 601a, please refer to the description in the above embodiments.

[0116] In summary, in the information update method provided in one embodiment of this disclosure, the UE receives configuration information from the base station indicating a time window, wherein the time window indicates the delayed effective time of the updated cell-specific offset value. When the UE receives the updated cell-specific offset value from the base station, it uses the updated cell-specific offset value based on the time window. Therefore, in this embodiment of the disclosure, the effective time of the updated cell-specific offset value is specifically determined through a time window to ensure that when each UE in the cell sends uplink information to the base station based on the updated cell-specific offset value, the base station has the same understanding of the cell-specific offset value used by different UEs, thus ensuring communication reliability.

[0119] For details regarding step 601b, please refer to the description in the above embodiments.

[0120] In summary, in the information update method provided in one embodiment of this disclosure, the UE receives configuration information from the base station indicating a time window, wherein the time window indicates the invalidation time of the updated cell-specific offset value. When the UE receives the updated cell-specific offset value from the base station, it uses the updated cell-specific offset value based on the time window. Therefore, in this embodiment of the disclosure, the effective time of the updated cell-specific offset value is specifically determined through a time window to ensure that when each UE in the cell sends uplink information to the base station based on the updated cell-specific offset value, the base station has the same understanding of the cell-specific offset value used by different UEs, thus ensuring communication reliability.

[0121] Furthermore, it should be noted that, in addition to "receiving configuration information for indicating a time window by receiving UE-specific signaling and / or public signaling" as described in the above embodiments, in another embodiment of this disclosure, the UE may also obtain configuration information for indicating a time window through a protocol-agreed method, or may receive configuration information for indicating a time window by receiving other signaling sent by the base station.

[0123] Step 701a: In response to receiving configuration information indicating a time window, within which the UE performs communication operations that require the use of a cell-specific offset value based on a UE-specific offset value.

[0124] For details regarding step 701a, please refer to the description in the above embodiments.

[0125] In summary, in the information update method provided in one embodiment of this disclosure, the UE receives configuration information sent by the base station indicating a time offset value. This time window indicates the invalidation time of the updated cell-specific offset value. When the UE receives the updated cell-specific offset value sent by the base station, it uses the updated cell-specific offset value based on this time offset value. Therefore, in this embodiment of the disclosure, the effective time of the updated cell-specific offset value is specifically determined by the time offset value to ensure that when each UE in the cell sends uplink information to the base station based on the updated cell-specific offset value, the base station has the same understanding of the cell-specific offset value used by different UEs, thus ensuring communication reliability.

[0126] Figure 7b This is a flowchart illustrating an information update method provided in one embodiment of the present disclosure. The method is executed by a UE that supports satellite communication. Figure 7a As shown, the information update method may include the following steps:

[0127] Step 701b: In response to receiving configuration information indicating a time window, within which the UE does not perform communication operations that require the use of a cell-specific offset.

[0128] For details regarding step 701b, please refer to the description in the above embodiments.

[0129] In summary, in the information update method provided in one embodiment of this disclosure, the UE receives configuration information sent by the base station indicating a time offset value, wherein the time offset value indicates the delayed effective time of the updated cell-specific offset value. When the UE receives the updated cell-specific offset value sent by the base station, it uses the updated cell-specific offset value based on the time offset value. Therefore, in this embodiment of the disclosure, the effective time of the updated cell-specific offset value is specifically determined by the time offset value to ensure that when each UE in the cell sends uplink information to the base station based on the updated cell-specific offset value, the base station has the same understanding of the cell-specific offset value used by different UEs, thus ensuring communication reliability.

[0130] Furthermore, it should be noted that the above embodiments are exemplary embodiments provided by this disclosure, and the above embodiments can also be combined and merged with each other. For example, Figure 2 and... Figure 3 The corresponding implementations can be combined and merged, that is, the base station can simultaneously send configuration information to the UE to indicate the time offset value and the time window, and the UE can use the updated cell-specific offset value based on the time offset value and the time window.

[0131] Figure 8This is a flowchart illustrating an information update method provided in one embodiment of the present disclosure. The method is executed by a base station supporting satellite communication. Figure 8 As shown, the information update method may include the following steps:

[0132] Step 801: Determine the time offset value and / or time window.

[0133] In one embodiment of this disclosure, the base station can determine a time offset value based on the maximum RTT of signal transmission within its coverage area. In another embodiment, the time offset value can be used to indicate the delayed effective time of an updated cell-specific offset value. Furthermore, in another embodiment, the time offset values ​​may differ for different UEs within the cell. Also, in another embodiment, the magnitude of the time offset value may be inversely proportional to the distance between the UE and the base station. For example, UEs farther from the base station have smaller time offset values, and UEs closer to the base station have larger time offset values.

[0134] It should be noted that, in one embodiment of this disclosure, the time offset value should satisfy the following condition: the time offset value enables the base station to have the same understanding of the cell-specific offset value used by each UE within the cell. That is, when each UE within the cell communicates with the base station using the updated cell-specific offset value after a corresponding time offset value delay, there is no ambiguity period for the base station. This ambiguity period is a period during which different UEs within the cell use different cell-specific offset values ​​when communicating with the base station due to differences in distance between each UE and the base station. For example, some UEs within the cell (e.g., near-end UEs closer to the base station) communicate with the base station using the updated cell-specific offset value, while other UEs within the cell (e.g., far-end UEs closer to the base station) communicate with the base station using the cell-specific offset value before the update.

[0135] Furthermore, in one embodiment of this disclosure, the time offset value can be a fixed value. In another embodiment of this disclosure, the time offset value can be a configurable value.

[0136] Furthermore, the aforementioned time window can be used to indicate the invalid period of the updated cell-specific offset value. Specifically, in one embodiment of this disclosure, the time window should satisfy the following condition: the time window ensures that the base station has the same understanding of the cell-specific offset value used by each UE within the cell. That is, when each UE within the cell communicates with the base station using the updated cell-specific offset value after a time window delay, there is no ambiguity period for the base station. This ambiguity period is a period during which different UEs within the cell use different cell-specific offset values ​​when communicating with the base station due to differences in distance between each UE and the base station. For example, some UEs within the cell (such as near-end UEs closer to the base station) communicate with the base station using the updated cell-specific offset value, while other UEs within the cell (such as far-end UEs closer to the base station) communicate with the base station using the cell-specific offset value before the update.

[0137] Step 802: Send configuration information to the UE to indicate the time offset value and / or time window.

[0138] In one embodiment of this disclosure, a method for a base station to send configuration information to a UE for indicating a time offset value and / or a time window may include:

[0139] The configuration information is sent to the UE via UE-specific signaling;

[0140] The configuration information is sent to the UE via common signaling.

[0141] Step 803: Send the updated cell-specific offset value to the UE.

[0142] In one embodiment of this disclosure, the base station may determine whether to instruct the UE to update the cell-specific offset value based on the satellite communication scenario in which the UE and the base station are located.

[0143] Specifically, in one embodiment of this disclosure, the base station determines the satellite communication scenario of the base station and the UE based on ephemeris information. If the base station determines that the satellite communication scenario of the UE and the base station is a GEO scenario, the base station does not instruct the UE to update the cell-specific offset value; that is, the base station does not send the updated cell-specific offset value to the UE. If the base station determines that the satellite communication scenario of the UE and the base station is an NGSO scenario, the base station will send the updated cell-specific offset value to the UE.

[0144] It should also be noted that, in one embodiment of this disclosure, the execution order of steps 801-803 is merely one possible execution order for this example, and is not a fixed order. For example, in one embodiment of this disclosure, there is no fixed order between steps 802 and 803. Step 802 can be executed first, followed by step 803, or step 803 can be executed first, followed by step 802.

[0145] Furthermore, other details regarding steps 801-803 above can be found in the description of the foregoing embodiments, and will not be repeated here.

[0146] In summary, in the information update method provided in one embodiment of this disclosure, the UE receives configuration information sent by the base station indicating a time offset value and / or a time window. The time offset value indicates the delayed effective time of the updated cell-specific offset value, and the time window indicates the invalidation time of the updated cell-specific offset value. When the UE receives the updated cell-specific offset value sent by the base station, it uses the updated cell-specific offset value based on the time offset value and / or the time window. Therefore, in this embodiment of the disclosure, the effective time of the updated cell-specific offset value is specifically determined through the time offset value and / or the time window to ensure that when each UE in the cell sends uplink information to the base station based on the updated cell-specific offset value, the base station has the same understanding of the cell-specific offset value used by different UEs, thus ensuring communication reliability.

When the UE receives the updated cell-specific offset value sent by the base station, it uses the updated cell-specific offset value based on the time offset value and / or the time window. Therefore, in this embodiment of the disclosure, the effective time of the updated cell-specific offset value is specifically determined through the time offset value and / or the time window to ensure that when each UE in the cell sends uplink information to the base station based on the updated cell-specific offset value, the base station has the same understanding of the cell-specific offset value used by different UEs, thus ensuring communication reliability.
