[0028] Embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0029] In order to facilitate understanding of the solutions of the present disclosure, the relevant technologies involved in the present disclosure are introduced below.

[0030] In NR (New Radio), it is necessary to plan the services to be carried out in a specific time slot in advance, such as uplink data transmission services and downlink paging services. If the advance time is too long, it is easy for service requirements to change during this period, and the service needs to be replanned. If the advance time is too short, the service will not have enough time to complete data packaging and cannot be sent. Therefore, it is necessary to select an appropriate advance planning time for service planning.

[0031] In NR, in order to maintain uplink (UL) synchronization, the UE needs to continuously adjust the uplink timing advance (TA). In order to support a larger cell coverage, the maximum value of TA is 2019.92us, that is, the uplink service needs to be sent 2019.92us in advance. When the subcarrier spacing is 15khz, 2019.92us is about 2 time slots, and the service planning needs to be earlier than the actual service sending time. Therefore, the relevant scheme chooses to plan the uplink and downlink (DL) services 3 time slots in advance at the same time.

[0032] However, in the related scheme, service planning is performed 3 time slots in advance, which is too long in advance. There are many services that have been planned but not yet executed. When the needs of these services change, for example, when uplink scheduling information is received from the base station, these services need to be modified. Therefore, the related scheme needs to consider more service re-planning operations, and the design is complicated.

[0033] Therefore, the present disclosure proposes a service planning method. Under TA adjustment in the NR system, the uplink timing is adjusted comprehensively through the downlink timing and TA, and service planning is performed for the uplink and downlink respectively based on the adjusted uplink timing and downlink timing. The service planning is no longer affected by the TA value, and a suitable advance planning time can be selected. For example, based on the adjusted uplink timing and downlink timing, service planning is performed for the uplink and downlink respectively by 1 time slot in advance or 2 time slots in advance. The design is simple and flexible, and the problem of planning the uplink and downlink services 3 time slots in advance in the related technology is solved. The problem of too long advance time resulting in more service re-planning operations and complex design that need to be considered.

[0047] The service planning method, apparatus, device and storage medium provided by the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0048] Figure 2 Flow chart of a service planning method provided by an embodiment of the present disclosure, the method is applied to a communication system 100, such as Figure 2 As shown, the business planning method includes:

[0049] Step 201, obtaining uplink timing advance.

[0050] In an embodiment of the present disclosure, the uplink timing advance is used to adjust the uplink timing.

[0051] In some embodiments of the present disclosure, the communication system 100 includes structures such as radio frames, subframes, and time slots in time, the uplink timing includes uplink frame timing, and the uplink timing advance can be used to adjust the uplink frame timing.

[0052] In some embodiments of the present disclosure, in order to maintain uplink transmission synchronization of the communication system 100, the network device 102 sends a timing advance command (TAC) to the terminal 101 or provides the terminal with a fixed timing advance offset value N of its serving cell through a high-level parameter. TA，offset The uplink timing is adjusted to synchronize the uplink transmission between the network device 102 and the terminal 101.

[0053] Furthermore, in some embodiments of the present disclosure, the uplink timing advance is determined based on a first timing advance and a second timing advance, the first timing advance is a timing advance parsed from a timing advance command sent by the network device 102, and the second timing advance is a preset value or a timing advance offset value configured by the network device through high-level parameters.

[0054] Step 202: adjust the uplink timing according to the downlink timing and the uplink timing advance to obtain the adjusted uplink timing.

[0055] In some embodiments of the present disclosure, the uplink timing is adjusted according to the downlink timing and the uplink timing advance, and the adjusted uplink timing includes: determining the downlink timing based on the interrupt timer, subtracting the uplink timing advance from the downlink timing, and obtaining the adjusted uplink timing, and the formula is: uplink timing = downlink timing - uplink timing advance TA.

[0056] For example, if the current downlink timing is 10 ms and the uplink timing advance is 1.5 ms, then the uplink timing is 10 ms-1.5 ms=8.5 ms.

[0057] Step 203: Plan uplink services based on the adjusted uplink timing, and / or plan downlink services based on the downlink timing.

[0058] In an embodiment of the present disclosure, the adjusted uplink timing and downlink timing are no longer aligned, and services are planned for the uplink and downlink respectively based on the adjusted uplink timing and downlink timing.

[0059] In some embodiments of the present disclosure, service planning refers to planning the services to be performed in a specific time slot in advance for a period of time, and the services to be performed include uplink data transmission services, downlink paging services, etc.

[0060] In some embodiments of the present disclosure, since service planning is performed separately for uplink and downlink, service planning is no longer affected by the TA value, and there is no need to perform service adjustment 3 time slots in advance. A suitable advance planning time can be selected, for example, service planning can be performed for the uplink and downlink links respectively 1 time slot in advance based on the adjusted uplink timing and downlink timing. The design is simple and flexible.

[0061] In summary, according to the service planning method proposed in the present invention, the method is applied to the communication system 101, and the method includes: obtaining an uplink timing advance; adjusting the uplink timing according to the downlink timing and the uplink timing advance to obtain the adjusted uplink timing; planning the uplink service based on the adjusted uplink timing, and / or planning the downlink service based on the downlink timing. The method of the present invention adjusts the uplink timing through the downlink timing and the uplink timing advance, and based on the uplink and downlink timing, the appropriate advance planning time can be selected to plan the services for the uplink and downlink respectively, and the design is simple and flexible.

[0062] based on Figure 2 The embodiment shown, Figure 3 The flowchart of a service planning method proposed in the present disclosure is further shown, and the method is applied to the communication system 100 .

[0063] like Figure 3 As shown, the method includes the following steps.

[0064] Step 301 : Acquire a first timing advance, where the first timing advance is a timing advance parsed from a timing advance command sent by the network device 102 .

[0065] In some embodiments of the present disclosure, obtaining the first timing advance includes: receiving a random access response message sent by the network device 102; obtaining a first timing advance command from the random access response message, parsing the first timing advance command, and obtaining a basic value of the timing advance; and obtaining the first timing advance according to the basic value of the timing advance and the subcarrier spacing.

[0066] In some embodiments of the present disclosure, the method also includes: in response to receiving a link layer control MAC CE (Medium Access Control Control Element) message sent by the network device 102, obtaining a second timing advance command from the MAC CE message; parsing the second timing advance command to obtain an adjustment value of the timing advance; and adjusting the first timing advance based on the adjustment value and the subcarrier spacing.

[0067] In some embodiments of the present disclosure, the network device 102 sends a random access response message to the terminal 101, the message includes a first timing advance command, and obtains the timing offset T indicated by the first timing advance command. A , based on the timing advance T A and the subcarrier spacing u, the first timing advance is obtained, and the specific formula is: Among them, N TA represents the first timing advance, T AThe value range is expressed as T A =0,1,…,3846, the value range of μ is expressed as μ={0,1,2,3,4}, and the specific value of μ depends on the subcarrier spacing.

[0068] In some embodiments of the present disclosure, in response to receiving a MAC CE message sent by the network device 102, a second timing advance command is obtained from the MAC CE message, and a timing advance amount T indicated by the second timing advance command is obtained. A , based on the timing advance T A and subcarrier spacing u, adjust the first timing advance, and the adjustment formula is: Among them, N TA_old is the first timing advance before adjustment, T A The value range is expressed as T A =0,1,…,63,N TA is the adjusted first timing advance, the value range of μ is expressed as μ={0,1,2,3,4}, and the value of μ depends on the subcarrier spacing.

[0069] In summary, the first timing advance N TA The calculation formula is as follows:

[0070]

[0071] Step 302: Obtain a second timing advance, where the second timing advance is a preset value or a timing advance offset value configured by the network device.

[0072] In some embodiments of the present disclosure, obtaining the second timing advance includes: receiving a first message sent by a network device 102, wherein the first message carries configuration parameters of a service cell where a terminal 101 is located; in response to obtaining a timing advance offset parameter from the first message, determining a timing advance offset value configured by the timing advance offset parameter as the second timing advance.

[0073] In some embodiments of the present disclosure, the method further includes: in response to not obtaining a timing advance offset parameter from the first message, determining a preset value as a second timing advance, wherein the preset value is related to a signal multiplexing mode and a frequency band of an uplink.

[0074] In some embodiments of the present disclosure, the second timing advance is related to different frequency bands (FR1 / FR2) and duplex modes (TDD / FDD). The network device provides the terminal 101 with a fixed timing advance offset value of the serving cell through the high-level parameter ServingCellConfigCommon or nTimingAdvance-Offset in ServingCellConfigCommonSIB. For the frequency band FR1, the fixed timing advance offset value can be 0, 25600 or 39936. If the terminal 101 is not provided with the n-TimingAdvanceOffset of the serving cell, the second timing advance is a preset value of 25600. For the frequency band FR2, the preset value is fixed to 13792.

[0075] Step 303: Determine an uplink timing advance according to the first timing advance and the second timing advance.

[0076] In some embodiments of the present disclosure, determining the uplink timing advance based on the first timing advance and the second timing advance includes: calculating the product of the sum of the first timing advance and the second timing advance and the time unit of the communication system 100, and determining the calculation result as the uplink timing advance.

[0077] In some embodiments of the present disclosure, the communication system 100 is 5G NR, and the time unit calculation formula of 5G NR is: Where Δf max =480*10 3 Hz, Δf max Indicates the maximum subcarrier spacing, N f =4096, N f represents the number of sampling points. The calculation formula for determining the uplink timing advance is: T TA =(N TA +N TA,offset )T C , where T TA Indicates the uplink timing advance, N TA represents the first timing advance, N TA，offset Indicates the second timing advance.

[0078] Step 304: adjust the uplink timing according to the downlink timing and the uplink timing advance to obtain the adjusted uplink timing.

[0079] In some embodiments of the present disclosure, the uplink timing is adjusted according to the downlink timing and the uplink timing advance, and the adjusted uplink timing includes: determining the downlink timing based on the interrupt timer, subtracting the uplink timing advance from the downlink timing, and obtaining the adjusted uplink timing, and the formula is: uplink timing = downlink timing - uplink timing advance TA.

[0080] For example, if the current downlink timing is 10 ms and the uplink timing advance is 1.5 ms, then the uplink timing is 10 ms-1.5 ms=8.5 ms.

[0081] In some embodiments of the present disclosure, Figure 4 As shown, the uplink timing advance T TA =(N TA +N TA,offset )T C Used to adjust the uplink timing relative to the downlink timing so that the uplink and downlink timings are scheduled separately.

[0082] Step 305: Plan uplink services based on the adjusted uplink timing, and / or plan downlink services based on the downlink timing.

[0083] It should be noted that Figure 5 An example diagram of a business planning-related solution is provided. As shown in Figure 5, in the related solution, the uplink and downlink are simultaneously planned for business 3 time slots in advance. There are many businesses that have been planned but not yet executed. During the period when the business is waiting to be executed, it is very easy to have a scenario where the completed business plan needs to be modified due to changes in business requirements. This requires a lot of business re-planning operations and the design is complex.

[0084] In the embodiments of the present disclosure, service planning is performed separately for the uplink and downlink. Service planning is no longer affected by the TA value, and there is no need to make service adjustments 3 time slots in advance. A suitable advance planning time can be selected, which solves the problem that the related technology performs planning 3 time slots in advance, resulting in redundant and complex processing such as modification and revocation in NR flexible scheduling.

[0085] In some embodiments of the present disclosure, a suitable advance planning time can be selected for service planning according to the implementation scenario. For example, uplink services can be planned one or two time slots in advance or at other suitable times according to the adjusted uplink timing, and / or downlink services can be planned one or two time slots in advance according to the downlink timing, and the present disclosure is not limited thereto.

[0086] In some embodiments of the present disclosure, planning uplink services based on adjusted uplink timing, and / or planning downlink services based on downlink timing includes: planning uplink services one time slot in advance according to the adjusted uplink timing, and / or planning downlink services one time slot in advance according to the downlink timing.

[0087] In some embodiments of the present disclosure, Figure 6 As shown, based on the adjusted uplink timing and downlink timing, uplink and downlink service planning is performed one time slot in advance respectively, which significantly reduces the time from service planning to service execution, greatly reduces the scenarios for modifying the completed service planning, and significantly reduces the design complexity.

[0088] For example, if the current time slot is the nth time slot, the network device 102 sends a notification to the terminal 101 to send an uplink data service in the n+2th time slot. In the related scheme, the service planning is performed 3 time slots in advance, and the service of the n+2th time slot has been planned in the n-1th time slot. At this time, it is necessary to modify the completed service planning and notify the RF module, which is complex in design. In the scheme disclosed in the present invention, the service of the n+2th time slot is planned in the n+1th time slot, so it is only necessary to wait until the n+1th time slot to perform service planning, and no additional modification operations are required, which is simple in design.

[0089] In summary, the service planning method proposed in the present invention is applied to the communication system 100 for execution. The present invention adjusts the uplink timing by advancing the downlink timing and the uplink timing, and plans the uplink and downlink services in advance by 1 or 2 time slots or other suitable times based on the adjusted uplink timing and downlink timing, thereby solving the problem of planning the uplink and downlink services 3 time slots in advance in the related art, and the problem that the advance time is too long, resulting in more service re-planning operations and complex design that need to be considered.
