[0032] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In order to facilitate a clearer understanding of the embodiments of the present invention, some relevant background knowledge is first introduced as follows.

[0034] LTE is scheduled in units of 1ms subframes, while NR is scheduled in units of time slots, and different subcarrier spacings represent different time slot lengths. For example:

[0035] When the subcarrier spacing is 15kHz, each subframe has one slot (time slot), and the time length of a slot is 1ms;

[0036] When the subcarrier spacing is 30kHz, each subframe has two slots, and the time length of a slot is 0.5ms;

[0037] When the subcarrier spacing is 60kHz, each subframe has 4 slots, and the time length of a slot is 0.25ms;

[0038] Currently, the main subcarrier spacing used is 30kHz, that is, the time slot length is 0.5ms.

[0039] The existing NR time slot allocation method generally requires sending the time slot configuration message to the high layer, MAC layer, physical layer and radio frequency through OM. This method can easily result in inconsistent time slot configurations received by each sub-module. At the same time, most of the existing time slot configurations are time slot level configurations.

[0040] In order to overcome the above-mentioned defects, the present invention provides a method, device, electronic device and storage medium for obtaining time slot ratio, which can realize a top-down unified management method from high-level to radio frequency, and uniformly use a set of time slot ratios, which can overcome the defect of inconsistent time slot configuration in the prior art, and the present invention also realizes symbol-level time slot configuration, which is more flexible than the existing time slot ratio method.

[0041] Combine the following Figure 1-Figure 3 The invention describes a method, a device, an electronic device and a storage medium for obtaining a time slot ratio.

[0042] Figure 1 is a flow chart of a method for obtaining time slot ratio provided by the present invention, such as Figure 1 As shown, the method includes:

[0043] Step 100, the control layer obtains the target time slot ratio information corresponding to the target uplink and downlink ratio period from the local database, and forwards the target time slot ratio information to the MAC layer.

[0044] Specifically, in an embodiment of the present invention, the high layer can be controlled to obtain the target time slot ratio information corresponding to the target uplink and downlink ratio period from the local database, and forward the target time slot ratio information to the MAC layer, wherein the target uplink and downlink ratio period is determined based on the service type, and the local database stores time slot ratio information corresponding to a plurality of different uplink and downlink ratio periods.

[0045] Step 110, controlling the MAC layer to determine the uplink and downlink configuration mode of each symbol in each time slot within the target uplink and downlink configuration period based on the target time slot ratio information, and forwarding the uplink and downlink configuration mode of each symbol in each time slot to the physical layer.

[0046] Specifically, in an embodiment of the present invention, the MAC layer can be controlled to calculate the uplink and downlink configuration mode of each symbol in each time slot within the target uplink and downlink ratio period based on the target time slot ratio information obtained from the higher layer, and send the uplink and downlink configuration mode of each symbol in each time slot to the physical layer during the initial cell establishment process.

[0047] Optionally, the MAC layer may be controlled to calculate the uplink and downlink configuration mode of each symbol in each time slot according to the uplink and downlink configuration of each time slot and the uplink and downlink symbol configuration of the special subframe, and forward it to the physical layer.

[0048] Step 120: Control the physical layer to forward the uplink and downlink configuration mode of each symbol in each time slot to the radio frequency system through a CSR (Cell Specific Register) packet.

[0049] Specifically, in an embodiment of the present invention, after determining that the physical layer receives the uplink and downlink configuration mode of each symbol in each time slot, the physical layer can be controlled to forward the uplink and downlink configuration mode of each symbol in each time slot sent by the MAC layer to the radio frequency system through a CSR packet.

[0050] It can be understood that the method for obtaining time slot ratios provided by the present invention realizes a top-down unified management mode from high-level to radio frequency, uniformly uses a set of time slot ratios, and overcomes the defect of inconsistent time slot configuration in the prior art.

[0051] The method for obtaining time slot ratio provided by the present invention obtains the target time slot ratio information corresponding to the target uplink and downlink ratio period from the local database by controlling the high layer, and forwards it to the MAC layer, then controls the MAC layer to determine the uplink and downlink configuration mode of each symbol in each time slot within the target uplink and downlink ratio period based on the target time slot ratio information, and forwards the uplink and downlink configuration mode of each symbol in each time slot to the physical layer, and finally controls the physical layer to forward the uplink and downlink configuration mode of each symbol in each time slot to the radio frequency system through the CSR packet. On the one hand, multiple time slot ratios can be sent down for different service types, and on the other hand, the time slot ratio is obtained by adopting the form of CSR packet forwarding, which is not only simple and efficient but also can ensure the complete uniformity of the time slot configuration of the entire system.

[0052] Optionally, before the controlling high layer obtains the target time slot ratio information corresponding to the target uplink and downlink ratio period from the local database, the method further includes:

[0053] The time slot ratio information corresponding to different uplink and downlink ratio periods is configured in the local database, and the different uplink and downlink ratio periods include the target uplink and downlink ratio period.

[0054] Specifically, time slot ratio information corresponding to different uplink and downlink ratio periods may be pre-configured in a local database, wherein the different uplink and downlink ratio periods include a target uplink and downlink ratio period.

[0055] Optionally, time slot ratio information corresponding to all uplink and downlink ratio periods may be pre-configured in a local database. For example, the values ​​of the uplink and downlink ratio periods may include: 0.5ms, 0.625ms, 1ms, 1.25ms, 2ms, 2.5ms, 5ms and 10ms.

[0056] The present invention realizes flexible uplink and downlink subframe ratio of the NR system by adopting the method of "flexible configuration of the database and automatic delivery of MAC, and forwarding of the physical layer to the radio frequency", so that the radio frequency system can flexibly obtain any time slot ratio, and is no longer limited to several fixed time slot ratio methods in 4G.

[0057] Optionally, controlling the physical layer to forward the uplink and downlink configuration mode of each symbol in each time slot to the radio frequency system through a CSR packet includes:

[0058] Controlling the physical layer to convert the uplink and downlink configuration mode of each symbol in each time slot into time slot configuration information of a target format; the target format is the time slot configuration format required by the radio frequency system;

[0059] The physical layer is controlled to forward the time slot configuration information in the target format to the radio frequency system through a CSR packet.

[0060] Specifically, in an embodiment of the present invention, after determining that the physical layer receives the uplink and downlink configuration modes of each symbol in each time slot forwarded by the MAC layer, the physical layer can be controlled to first convert the uplink and downlink configuration modes of each symbol in each time slot into time slot configuration information in the time slot configuration format required by the radio frequency system, and then the physical layer can be controlled to forward the time slot configuration information in the target format to the radio frequency system through a CSR packet.

[0061] For example, Table 1 shows the relevant information specifically included in the CSR packet, wherein "Slot Format Configuration" includes relevant information about the time slot configuration.

[0062] Table 1 CSR package

[0063] Package Name Composition and function Initial configuration Carrier frequency, timing advance offset Parameter set configuration Subcarrier spacing Timeslot format configuration Uplink and downlink configuration mode for each symbol

[0064] Optionally, the time slot allocation information includes:

[0065] The number of downlink time slots, the number of downlink symbols, the number of uplink time slots and the number of uplink symbols.

[0066] Specifically, the time slot ratio information corresponding to different uplink and downlink ratio periods configured in the local database includes but is not limited to the number of downlink time slots, the number of downlink symbols, the number of uplink time slots and the number of uplink symbols.

[0067] Optionally, the above time slot allocation information may be configured in a local database based on user requirements.

[0068] For example, when the time slot ratio required by the user is DDDDDDDSUU and the S ratio is 6:4:4, the number of downlink time slots can be configured as 7, the number of downlink symbols can be configured as 6, the number of uplink time slots can be configured as 2, and the number of uplink symbols can be configured as 4 in the local database.

[0069] Optionally, when any one of the different uplink and downlink ratio periods is a double period, an enabling switch is provided between the time slot ratio information corresponding to the first period in the double period and the time slot ratio information corresponding to the second period in the double period.

[0070] Specifically, when the time slot ratio information of the uplink and downlink ratio period is configured as a double period in the local database, an enable switch can be set between the time slot ratio information corresponding to the first period in the double period and the time slot ratio information corresponding to the second period, as shown in Table 2. Taking the time slot ratio information configuration corresponding to a 0.5ms double period when the BWP (Bandwidth Part) subcarrier spacing is 30kHz as an example, it is introduced how to set the time slot ratio in the local database.

[0071] Table 2 Uplink and downlink configuration example in the local database (0.5ms double cycle)

[0072]

[0073] It is understandable that by setting the enable switch, it is possible to distinguish whether the uplink and downlink ratio cycle is a double cycle, and the enable switch can also be used to distinguish the uplink and downlink ratio modes of the first cycle and the second cycle. For example, the configuration expressed in Table 2 is "DDDSUDDSUU", where the first 5 symbols are the first cycle and the last 5 symbols are the second cycle. At this time, it is necessary to turn on the enable switch to distinguish the first cycle from the second cycle.

[0074] The present invention flexibly configures the local database, that is, designs the time slot ratio information corresponding to each uplink and downlink ratio period in the local database, so that the high layer can flexibly obtain the time slot ratio information matching different service types from the local database.

[0075] Optionally, the upper layer may directly read the time slot allocation information shown in Table 2 from the local database, and store the configuration information of each time slot.

[0076] For example, after the high layer obtains the time slot ratio information shown in Table 2, it can distinguish the configuration of each time slot and store it, that is: slot0: D (downlink time slot), slot1: D (downlink), slot2: D (downlink time slot), slot3: S (in the 14 symbols of the protection time slot: 10:2:2, the first 10 are downlink time slots, and the last 2 are uplink time slots), slot4: U (uplink time slot), slot5: D (downlink time slot), slot6: D (downlink time slot), slot7: S (in the 14 symbols of the protection time slot: 10:2:2, the first 10 are downlink time slots, and the last 2 are uplink time slots), slot8: U (uplink time slot), slot9: U (uplink time slot), and finally forward these time slot ratio information to the MAC layer.

[0077] Optionally, after the MAC layer receives the time slot ratio information sent by the higher layer, the MAC layer can parse the specific subframe configuration of each symbol of each time slot, for example: slot0: D (downlink time slot), the result parsed by the MAC layer is: slot0: symbol0-D, symbol1-D, symbol2-D, symbol3-D, symbol4-D, symbol5-D, symbol6-D, symbol7-D, symbol8-D, symbol9-D, symbol10-D, symbol11-D, symbol12-D, symbol13-D.

[0078] For example, it can be seen from Table 2 that slot 3 is a special time slot (because when the subcarrier spacing is 30kHz, there are 5 slots every 2.5ms, and in the configuration of the first half cycle of Table 2, the number of downlink time slots is 3 and the number of uplink time slots is 1, then slot0, slot1 and slot2 are downlink time slots D, slot4 is uplink time slot U, and slot3 is a special time slot), and the number of downlink symbols in Table 2 is 10, and the number of uplink symbols is 2, indicating that the uplink and downlink configuration of the special time slot is 10:2:2 (the first 10 are downlink time slots, the middle 2 are is a protection symbol, and the last two are uplink time slots), the result of slot3 parsed by the MAC layer is: slot3: symbol0-D, symbol1-D, symbol2-D, symbol3-D, symbol4-D, symbol5-D, symbol6-D, symbol7-D, symbol8-D, symbol9-D, symbol10-S, symbol11-S, symbol12-U, symbol13-U.

[0079] The present invention realizes time slot allocation for scheduling in time slots under different subcarrier intervals by adopting the method of "flexible database configuration combined with automatic MAC delivery and forwarding to the radio frequency by the physical layer", and can efficiently and accurately deliver configuration parameters to the radio frequency system, so that the entire radio frequency system can communicate normally in TDD (Time-division Duplex) mode, and can be applicable to a variety of different application scenarios.

[0080] The method for obtaining time slot ratio provided by the present invention obtains the target time slot ratio information corresponding to the target uplink and downlink ratio period from the local database by controlling the high layer, and forwards it to the MAC layer, then controls the MAC layer to determine the uplink and downlink configuration mode of each symbol in each time slot within the target uplink and downlink ratio period based on the target time slot ratio information, and forwards the uplink and downlink configuration mode of each symbol in each time slot to the physical layer, and finally controls the physical layer to forward the uplink and downlink configuration mode of each symbol in each time slot to the radio frequency system through the CSR packet. On the one hand, multiple time slot ratios can be sent down for different service types, and on the other hand, the time slot ratio is obtained by adopting the form of CSR packet forwarding, which is not only simple and efficient but also can ensure the complete uniformity of the time slot configuration of the entire system.

[0085] The third control module 230 is used to control the physical layer to forward the uplink and downlink configuration mode of each symbol in each time slot to the radio frequency system through a CSR packet.
