Description

[Technical Field]

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

[0002] In satellite communication systems, a cell-specific offset and a UE (User Equipment)-specific offset are typically introduced to compensate for transmission delays.

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

[0004] However, in the related art, because the distances between each UE and the base station in the same cell are different, the reception time of each UE for the updated system information transmitted by the base station is also different. That is, the time at which each UE acquires the updated cell-specific offset is different. At this time, the base station enters a fuzzy period. During this fuzzy period, when the base station communicates with different UEs, the cell-specific offsets used by the different UEs are different (i.e., the base station does not reveal which cell-specific offset the UE is using), which affects the reliability of communication. Summary of the Invention [Problem to be solved by the invention]

[0005] The information update method, device, user equipment, base station, and storage medium proposed in the present disclosure solve the technical problem that the information update method in the related art is likely to affect communication performance. [Means for solving the problem]

[0010] A communication device proposed by an embodiment of another aspect of the present disclosure includes a processor and a memory, wherein a computer program is stored in the memory, and the processor executes the computer program stored in the memory so that the communication device performs the information update method proposed by the embodiment of the first aspect described above.

[0013] A communication device proposed by an embodiment of another aspect of the present disclosure includes a processor and an interface circuit, the interface circuit being used to receive and transmit code instructions to the processor, and the processor executing the code instructions to perform the information update method proposed by an embodiment of another aspect.

This ensures that when each UE in a cell transmits uplink information to the base station based on the updated cell-specific offset, the base station has the same understanding of the cell-specific offset used by different UEs, thereby ensuring communication reliability.

[0018] Illustrative embodiments will now be described in detail, examples of which are illustrated in the drawings. Where the following description refers to the drawings, like numerals in different drawings represent the same or similar elements unless otherwise stated. The embodiments described in the following illustrative examples do not represent all embodiments consistent with embodiments of the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of embodiments of the present disclosure, as detailed in the appended claims.

[0019] The terms used in the embodiments of the present disclosure are merely for the purpose of describing particular embodiments and are not intended to limit the embodiments of the present disclosure.

Furthermore, the term "and / or" as used herein refers to any and all possible combinations of one or more of the associated listed items.

[0020] In embodiments of the present disclosure, terms such as first, second, and third may be used to describe various pieces of information, but it should be understood that such information should not be limited to these terms. These terms are merely used to distinguish between the same type of information. For example, first information can be referred to as second information, and similarly, second information can be referred to as first information, without departing from the scope of embodiments of the present disclosure. Depending on the context, the words "if" and "if" used herein can be interpreted as "when" or "in the case of" or "responsive to a determination."

[0021] 1a is a schematic diagram of communication between a UE and a base station in an information updating method of the related art provided by an embodiment of the present disclosure. As shown in FIG. 1a, a near-end UE close to a base station in a cell receives the updated system information transmitted from the base station first, while a far-end UE far from the base station in the cell receives the updated system information transmitted from the base station later. Because each UE receives the updated system information at a different time, a fuzzy period exists in the base station. During this fuzzy period, the near-end UE has already acquired the updated cell-specific offset and communicates with the base station using this updated cell-specific offset, while the far-end UE has not yet acquired the updated cell-specific offset and communicates with the base station using the original cell-specific offset, resulting in reduced communication reliability. Based on this, the present invention proposes an information updating method, device, user equipment, base station, and storage medium to solve the technical problem that the information updating method of the related art is prone to reducing communication reliability.

[0022] Hereinafter, an information updating method, device, user equipment, base station, and storage medium provided by an embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.

[0023] FIG. 1b is a schematic flow chart of an information updating method provided by one embodiment of the present disclosure, which is performed by a UE supporting satellite communication. As shown in FIG. 1b, the information updating method may include the following steps 101 to 103.

[0024] Step 101: Receive an updated cell-specific offset sent from a base station.

[0025] In one embodiment of the present disclosure, the base station may be a base station supporting satellite communications, and the UE may be a device providing voice and / or data connectivity to a user. The terminal device can communicate with one or more core networks via a Radio Access Network (RAN). The UE may be an Internet of Things terminal, such as a sensor device, a mobile phone (also called a "cellular" phone), or a computer with an Internet of Things terminal, and may be, for example, a fixed, portable, pocket-sized, handheld, computer-integrated, or vehicle-mounted device. For example, the UE may be a station (STA), subscriber unit, subscriber station, mobile station, mobile, remote station, access point, remote terminal, access terminal, user terminal, or user agent. Alternatively, the UE may be an unmanned aerial vehicle device. Alternatively, the UE may be an in-vehicle device, such as an electronic control unit with wireless communication capabilities or a wireless communication device with an external electronic control unit. Alternatively, the UE may be a roadside device, such as a street lamp, traffic light, or other roadside device with wireless communication capabilities.

[0026] In one embodiment of the present disclosure, the base station transmits a cell-specific offset to the UE through system information, specifically, the cell-specific offset can be included in the system information. After the base station transmits a cell-specific offset to the UE through system information, if a satellite in the satellite communication scene where the base station is located moves relative to the cell, the base station needs to update the cell-specific offset and transmit the updated cell-specific offset to the UE through the updated system information.

[0027] Based on this, the base station can decide whether to instruct the UE to update the cell-specific offset based on the satellite communication scene in which the UE and the base station are located.

[0028] Specifically, in one embodiment of the present disclosure, the base station determines the satellite communication scene in which the base station and the UE are located based on the ephemeris information. If the base station determines that the satellite communication scene in which the UE and the base station are located is a GEO (Geostationary Earth Orbit) scene, it indicates 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, i.e., the base station does not transmit the updated cell-specific offset to the UE. If the base station determines that the satellite communication scene in which the UE and the base station are located is a NGSO (Non-Geostationary Orbit) scene, it indicates that the satellite moves relative to the ground. In this case, if the satellite moves relative to the ground, the base station needs to transmit the updated cell-specific offset to the UE via the updated system information.

[0029] Step 102: receiving configuration information sent from a base station to indicate a time offset and / or a time window;

[0030] In one embodiment of the present disclosure, the time offset can be used to indicate the delay effective time of the updated cell-specific offset, and the time window can be used to indicate the invalid time of the updated cell-specific offset. Further, detailed descriptions of the time offset and the time window will be provided in the following examples.

[0031] Furthermore, in one embodiment of the present disclosure, the step of the UE receiving configuration information transmitted from the base station for indicating the time offset and / or the time window may include at least one of the steps of receiving the configuration information transmitted by the base station via user equipment specific (UE-specific) signaling and receiving the configuration information transmitted by the base station via common signaling.

[0032] Step 103: Using the updated cell-specific offset based on the time offset and / or the time window.

[0033] A detailed description of step 103 will be given in the following examples.

[0034] In one embodiment of the present disclosure, the execution order of the above steps 101 to 103 is merely an execution order in the example of the present disclosure and is not a fixed order. For example, in one embodiment of the present disclosure, there is no fixed order between the above steps 101 and 102, and step 101 may be executed first and then step 102, or step 102 may be executed first and then step 101.

[0035] As can be seen from the above, in an information updating method provided by an embodiment of the present disclosure, a UE receives configuration information transmitted from a base station to indicate a time offset and / or a time window, where the time offset is used to indicate a delay effective time of the updated cell-specific offset and the time window is used to indicate an invalid time of the updated cell-specific offset. When the UE receives the updated cell-specific offset transmitted from the base station, the UE uses the updated cell-specific offset based on the time offset and / or the time window. As can be seen from the above, in the embodiment of the present disclosure, the effective time of the updated cell-specific offset is specifically determined based on the time offset and / or the time window. This ensures that when each UE in a cell transmits uplink information to the base station based on the updated cell-specific offset, the base station has the same understanding of the cell-specific offset used by different UEs, thereby ensuring communication reliability.

[0036] FIG. 2a is a schematic flow chart of an information updating method provided by one embodiment of the present disclosure, which is performed by a UE supporting satellite communication. As shown in FIG. 2a, the information updating method may include the following steps 201 to 203.

[0037] Step 201: Receive an updated cell-specific offset sent from a base station.

[0038] For the description of step 201, please refer to the description of the above embodiment, and the description of the embodiment of the present disclosure will be omitted here.

[0039] Step 202: receiving setting information for indicating a time offset sent from a base station;

[0040] In one embodiment of the present disclosure, this time offset can be used to indicate the delay effective time of the updated cell-specific offset.

[0041] In one embodiment of the present disclosure, the time offset may be determined by the base station based on the round trip time (RTT) of signal transmission within its coverage area. In one embodiment of the present disclosure, the time offset corresponding to different UEs in a cell may be different. In one embodiment of the present disclosure, the magnitude of the time offset may be inversely proportional to the distance between the UE and the base station. For example, the smaller the time offset corresponding to a UE farther from the base station, the larger the time offset corresponding to a UE closer to the base station.

[0042] Furthermore, in one embodiment of the present disclosure, this time offset may be a fixed value, while in another embodiment of the present disclosure, this time offset may be a configurable value.

[0043] Step 203: Use the updated cell-specific offset based on the time offset.

[0044] In one embodiment of the present disclosure, using the updated cell-specific offset based on the time offset may include communicating with the base station using the pre-updated cell-specific offset within the time offset after the updated cell-specific offset is received, and / or communicating with the base station using the updated cell-specific offset after the time offset is delayed.

[0045] In one embodiment of the present disclosure, this time offset should satisfy a condition that the base station has the same understanding of the cell-specific offset used by each UE in the cell. That is, when each UE in the cell communicates with the base station using the updated cell-specific offset after delaying the corresponding time offset, there is no fuzzy period for the base station. This fuzzy period means that the time at which each UE receives the updated cell-specific offset differs due to, for example, the difference in distance between each UE in the cell and the base station. Therefore, for the base station, there is a period during which different UEs in the cell use different cell-specific offsets when communicating with the base station. For example, some UEs in the cell (e.g., near-end UEs close to the base station) communicate with the base station using the updated cell-specific offset, and other UEs in the cell (e.g., far-end UEs close to the base station) communicate with the base station using the pre-updated cell-specific offset.

[0046] 2B is a schematic diagram of communication between a UE and a base station in an information updating method provided by an embodiment of the present disclosure. As shown in FIG. 2B, the base station determines updated system information, which includes an updated cell-specific offset. The base station then broadcasts the updated system information to each UE in the cell. The near-end UE receives the updated system information first, and the far-end UE receives the updated system information later. After receiving the updated system information, each UE analyzes the updated system information to obtain an updated cell-specific offset. After obtaining the updated cell-specific offset, each UE does not immediately communicate with the base station based on the updated cell-specific offset, but first communicates with the base station based on the pre-updated cell-specific offset, and then delays the corresponding time offset before communicating with the base station based on the updated cell-specific offset. This ensures that the base stations have the same understanding of the cell-specific offset used by each UE in the cell, avoids the occurrence of fuzzy periods, and ensures communication reliability.

[0047] As can be seen from the above, in an information updating method provided by an embodiment of the present disclosure, a UE receives configuration information transmitted from a base station to indicate a time offset and / or a time window, where the time offset is used to indicate a delay effective time of the updated cell-specific offset and the time window is used to indicate an invalid time of the updated cell-specific offset. When the UE receives the updated cell-specific offset transmitted from the base station, the UE uses the updated cell-specific offset based on the time offset and / or the time window. As can be seen from the above, in the embodiment of the present disclosure, the effective time of the updated cell-specific offset is specifically determined based on the time offset and / or the time window. This ensures that when each UE in a cell transmits uplink information to the base station based on the updated cell-specific offset, the base station has the same understanding of the cell-specific offset used by different UEs, thereby ensuring communication reliability.

[0048] FIG. 3 is a schematic flow chart of an information updating method provided by one embodiment of the present disclosure, which is performed by a UE supporting satellite communication. As shown in FIG. 3, the information updating method may include the following steps 301 to 303.

[0049] Step 301: Receive an updated cell-specific offset sent from a base station.

[0050] For the description of step 301, please refer to the description of the above embodiment, and the description of the embodiment of the present disclosure will be omitted here.

[0051] Step 302: receiving setting information for indicating a time window sent from a base station;

[0052] In one embodiment of the present disclosure, the time window can be used to indicate the invalid time of the updated cell-specific offset.Step 303: Use the updated cell-specific offset based on the time offset.

[0053] In one embodiment of the present disclosure, using the updated cell-specific offset based on the time offset may include communicating with the base station using the UE-specific offset within the time window, and communicating with the base station using the updated cell-specific offset after the time window and communicating using the pre-updated cell-specific offset before the time window.

[0054] Furthermore, the above method of "communicating with a base station using a UE-specific offset within this time window" may include at least one of the following: Method 1: Within this time window, the UE performs communication operations that require the use of a cell-specific offset based on the UE-specific offset. Method 2: Within this time window, the UE does not perform any communication operations that require the use of a cell-specific offset.

[0055] In one embodiment of the present disclosure, the above communication operation may specifically be an uplink operation and / or a downlink operation between the UE and the base station.

[0056] In one embodiment of the present disclosure, this time window should satisfy a condition that the base station has the same understanding of the cell-specific offset used by each UE in the cell. That is, when each UE in the cell communicates with the base station using the updated cell-specific offset after delaying the time window, there is no fuzzy period for the base station. This fuzzy period means that the time at which each UE receives the updated cell-specific offset differs due to the difference in distance between each UE in the cell and the base station. Therefore, for the base station, there is a period during which different UEs in the cell use different cell-specific offsets when communicating with the base station. For example, some UEs in the cell (e.g., near-end UEs close to the base station) communicate with the base station using the updated cell-specific offset, and other UEs in the cell (e.g., far-end UEs close to the base station) communicate with the base station using the pre-updated cell-specific offset.

[0057] It should be understood that the UE-specific offset may be determined according to protocol conventions, by transmitting signaling, or by other methods, and the present disclosure is not limited thereto.

[0058] As can be seen from the above, in an information updating method provided by an embodiment of the present disclosure, a UE receives configuration information transmitted from a base station to indicate a time offset and / or a time window, where the time offset is used to indicate a delay effective time of the updated cell-specific offset and the time window is used to indicate an invalid time of the updated cell-specific offset. When the UE receives the updated cell-specific offset transmitted from the base station, the UE uses the updated cell-specific offset based on the time offset and / or the time window. As can be seen from the above, in the embodiment of the present disclosure, the effective time of the updated cell-specific offset is specifically determined based on the time offset and / or the time window. This ensures that when each UE in a cell transmits uplink information to the base station based on the updated cell-specific offset, the base station has the same understanding of the cell-specific offset used by different UEs, thereby ensuring communication reliability.

[0059] FIG. 4a is a schematic flow chart of an information updating method provided by one embodiment of the present disclosure, which is performed by a UE supporting satellite communication. As shown in FIG. 4a, the information updating method may include the following steps 401a to 401b.

[0060] Step 401a: receiving configuration information for indicating a time offset sent by a base station through UE-specific signaling;

[0061] For the description of step 401a, please refer to the description of the above embodiment. As can be seen from the above, in the information updating method provided by an embodiment of the present disclosure, the UE receives configuration information transmitted from a base station for indicating a time offset, and this time offset is used to indicate the delay effective time of the updated cell-specific offset. When the UE receives the updated cell-specific offset transmitted from the base station, the UE uses the updated cell-specific offset based on the time offset. As can be seen from the above, in the embodiment of the present disclosure, the effective time of the updated cell-specific offset is specifically determined based on the time offset, so that when each UE in the cell transmits uplink information to the base station based on the updated cell-specific offset, the base station has the same understanding of the cell-specific offset used by different UEs, thereby ensuring communication reliability.

[0064] For the explanation of step 401b, please refer to the explanation of the above embodiment.

[0065] As can be seen from the above, in the information updating method provided by one embodiment of the present disclosure, the UE receives configuration information transmitted from the base station to indicate a time offset, which is used to indicate the delay effective time of the updated cell-specific offset. When the UE receives the updated cell-specific offset transmitted from the base station, the UE uses the updated cell-specific offset based on the time offset. As can be seen from the above, in the embodiment of the present disclosure, the effective time of the updated cell-specific offset is specifically determined based on the time offset, so that when each UE in the cell transmits uplink information to the base station based on the updated cell-specific offset, the base station has the same understanding of the cell-specific offset used by different UEs, thereby ensuring communication reliability.

[0066] FIG. 5 is a schematic flowchart of an information updating method provided by one embodiment of the present disclosure, which is performed by a UE supporting satellite communication. As shown in FIG. 5, the information updating method may include the following step 501:

[0067] Step 501: In response to receiving configuration information indicating a time offset, after an updated cell-specific offset is received, communicate with the base station using the pre-updated cell-specific offset within this time offset, and / or after this time offset is delayed, communicate with the base station using the updated cell-specific offset.

[0068] For the explanation of step 501, please refer to the explanation of the above embodiment.

[0069] As can be seen from the above, in the information updating method provided by one embodiment of the present disclosure, the UE receives configuration information transmitted from the base station to indicate a time offset, which is used to indicate the delay effective time of the updated cell-specific offset. When the UE receives the updated cell-specific offset transmitted from the base station, the UE uses the updated cell-specific offset based on the time offset. As can be seen from the above, in the embodiment of the present disclosure, the effective time of the updated cell-specific offset is specifically determined based on the time offset, so that when each UE in the cell transmits uplink information to the base station based on the updated cell-specific offset, the base station has the same understanding of the cell-specific offset used by different UEs, thereby ensuring communication reliability.

[0077] As can be seen from the above, in the information updating method provided by one embodiment of the present disclosure, the UE receives configuration information transmitted from the base station to indicate a time window, and this time window is used to indicate the invalidity period of the updated cell-specific offset. When the UE receives the updated cell-specific offset transmitted from the base station, the UE uses the updated cell-specific window based on the time window. As can be seen from the above, in the embodiment of the present disclosure, the validity period of the updated cell-specific offset is specifically determined based on the time window, so that when each UE in the cell transmits uplink information to the base station based on the updated cell-specific offset, the base station has the same understanding of the cell-specific offset used by different UEs, thereby ensuring communication reliability.

[0078] In addition to the UE "receiving configuration information for indicating a time window via UE-specific signaling and / or common signaling" described in the above embodiment, in another embodiment of the present disclosure, the UE can obtain the configuration information for indicating a time window in a manner agreed upon in a protocol, or can receive the configuration information for indicating a time window by receiving other signaling transmitted from the base station.

[0079] FIG. 7a is a schematic flowchart of an information updating method provided by one embodiment of the present disclosure, which is performed by a UE supporting satellite communication. As shown in FIG. 7a, the information updating method may include the following step 701a:

[0080] Step 701a, in response to receiving the configuration information indicating a time window, within the time window, the UE performs a communication operation that requires the use of a cell-specific offset based on the UE-specific offset.

[0081] For the explanation of step 701a, please refer to the explanation of the above embodiment.

[0082] As can be seen from the above, in the information updating method provided by one embodiment of the present disclosure, the UE receives configuration information transmitted from the base station to indicate a time offset, and this time window is used to indicate the invalid time of the updated cell-specific offset. When the UE receives the updated cell-specific offset transmitted from the base station, the UE uses the updated cell-specific offset based on the time offset. As can be seen from the above, in the embodiment of the present disclosure, the valid time of the updated cell-specific offset is specifically determined based on the time offset, so that when each UE in the cell transmits uplink information to the base station based on the updated cell-specific offset, the base station has the same understanding of the cell-specific offset used by different UEs, thereby ensuring communication reliability.

[0083] FIG. 7b is a schematic flow chart of an information updating method provided by one embodiment of the present disclosure, which is performed by a UE supporting satellite communication. As shown in FIG. 7a, the information updating method may include the following step 701b.

[0084] Step 701b, in response to receiving the configuration information indicating a time window, the UE does not perform a communication operation within the time window that requires the use of a cell-specific offset.

[0085] For the explanation of step 701b, please refer to the explanation of the above embodiment.

[0086] As can be seen from the above, in the information updating method provided by one embodiment of the present disclosure, the UE receives configuration information transmitted from the base station to indicate a time offset, which is used to indicate the delay effective time of the updated cell-specific offset. When the UE receives the updated cell-specific offset transmitted from the base station, the UE uses the updated cell-specific offset based on the time offset. As can be seen from the above, in the embodiment of the present disclosure, the effective time of the updated cell-specific offset is specifically determined based on the time offset, so that when each UE in the cell transmits uplink information to the base station based on the updated cell-specific offset, the base station has the same understanding of the cell-specific offset used by different UEs, thereby ensuring communication reliability.

[0087] It should be noted that the above embodiments are exemplary embodiments provided by the present disclosure, and the above embodiments can be combined with each other. For example, the embodiments corresponding to Figures 2 and 3 above can be combined, that is, the base station can simultaneously send configuration information for indicating the time offset and the time window to the UE, and the UE can use the updated cell-specific offset based on the time offset and the time window.

[0088] FIG. 8 is a schematic flow chart of an information updating method provided by one embodiment of the present disclosure, which is performed by a base station supporting satellite communication. As shown in FIG. 8, this information updating method may include the following steps 801 to 803.

[0089] Step 801: Determine a time offset and / or a time window.

[0090] In one embodiment of the present disclosure, the base station may determine the time offset based on the maximum RTT of signal transmissions within its coverage area. In one embodiment of the present disclosure, the time offset may indicate the delay effective time of the updated cell-specific offset. In one embodiment of the present disclosure, the time offsets corresponding to different UEs within a cell may be different. In one embodiment of the present disclosure, the magnitude of the time offset may be inversely proportional to the distance between the UE and the base station. For example, the smaller the time offset corresponding to a UE farther from the base station, the larger the time offset corresponding to a UE closer to the base station.

[0091] In one embodiment of the present disclosure, this time offset should satisfy a condition that the base station has the same understanding of the cell-specific offset used by each UE in the cell. That is, when each UE in the cell communicates with the base station using the updated cell-specific offset after delaying the corresponding time offset, there is no fuzzy period for the base station. This fuzzy period means that the time at which each UE receives the updated cell-specific offset differs due to the difference in distance between each UE in the cell and the base station. Therefore, for the base station, there is a period during which different UEs in the cell use different cell-specific offsets when communicating with the base station. For example, some UEs in the cell (e.g., near-end UEs close to the base station) communicate with the base station using the updated cell-specific offset, and other UEs in the cell (e.g., far-end UEs close to the base station) communicate with the base station using the pre-updated cell-specific offset.

[0092] Furthermore, in one embodiment of the present disclosure, this time offset may be a fixed value, while in another embodiment of the present disclosure, this time offset may be a configurable value.

[0093] Furthermore, the time window can indicate an invalid time of the updated cell-specific offset. Specifically, in one embodiment of the present disclosure, the time window should satisfy a condition that the base station has the same understanding of the cell-specific offset used by each UE in the cell. That is, when each UE in the cell communicates with the base station using the updated cell-specific offset after delaying the time window, there is no fuzzy period for the base station. This fuzzy period means that the time at which each UE receives the updated cell-specific offset differs due to the difference in distance between each UE in the cell and the base station. Therefore, for the base station, there is a period during which different UEs in the cell use different cell-specific offsets when communicating with the base station. For example, some UEs in the cell (e.g., near-end UEs close to the base station) communicate with the base station using the updated cell-specific offset, while other UEs in the cell (e.g., far-end UEs close to the base station) communicate with the base station using the pre-updated cell-specific offset.

[0094] Step 802: Send configuration information to the UE to indicate a time offset and / or a time window.

[0095] In one embodiment of the present disclosure, the step of transmitting configuration information to the UE for indicating a base station time offset and / or a time window includes the steps of transmitting the configuration information to the UE via UE-specific signaling and transmitting the configuration information to the UE via common signaling.

[0096] Step 803: Send the updated cell-specific offset to the UE.

[0097] In one embodiment of the present disclosure, the base station can determine whether to instruct the UE to update the cell-specific offset based on the satellite communication scene in which the UE and the base station are located.

[0098] Specifically, in one embodiment of the present disclosure, the base station determines the satellite communication scene in which the base station and the UE are located based on the ephemeris information. If the base station determines that the satellite communication scene in which the UE and the base station are located is a GEO scene, the base station does not instruct the UE to update the cell-specific offset, i.e., the base station does not transmit the updated cell-specific offset to the UE. If the base station determines that the satellite communication scene in which the UE and the base station are located is an NGSO scene, the base station transmits the updated cell-specific offset to the UE.

[0099] In one embodiment of the present disclosure, the execution order of the above steps 801 to 803 is merely an execution order in the example of the present disclosure and is not a fixed order. For example, in one embodiment of the present disclosure, there is no fixed order between the above steps 802 and 803, and step 802 may be executed first and then step 803, or step 803 may be executed first and then step 802.

[0100] For the explanation of steps 801 to 803 above, please refer to the explanation of the previous embodiment, and the explanation of the embodiment of the present disclosure will be omitted here.

[0101] As can be seen from the above, in an information updating method provided by an embodiment of the present disclosure, a UE receives configuration information transmitted from a base station for indicating a time offset and / or a time window, where the time offset is used to indicate a delay effective time of the updated cell-specific offset and the time window is used to indicate an invalid time of the updated cell-specific offset. When the UE receives the updated cell-specific offset transmitted from the base station, the UE uses the updated cell-specific offset based on the time offset and / or the time window. As can be seen from the above, in the embodiment of the present disclosure, the effective time of the updated cell-specific offset is specifically determined based on the time offset and / or the time window, so that when each UE in a cell transmits uplink information to the base station based on the updated cell-specific offset, the base station can ensure that the base station has the same understanding of the cell-specific offsets used by different UEs, thereby ensuring communication reliability.
