Description

Storage method and equipment of time slot format

Technical field

The present application relates to the communication field, and in particular to a storage method and device in a time slot format.

Background technique

^{5G NR (5 th Generation New RAT} (Radio Access Technology, RAT), a new radio access technology. 5G) introducing a plurality of subcarrier spacing in the frequency domain, different carriers may have different sub-carrier spacing. For example, the baseline is 15kHz, the subcarrier spacing can be 15kHz* ²ⁿ , n is an integer, for example, n can be -2,-1,0,1,2, etc., so that the subcarrier spacing can be from 3.75, 7.5 to 480kHz, up to 8 kinds. In the time domain, 5G NR can have multiple symbol lengths and slot lengths, and different subcarrier intervals can correspond to different symbol lengths. Among them, a time slot can be composed of at least one of downlink transmission symbols, flexible symbols (or, variable direction symbols, unknown direction symbols) and uplink transmission symbols, so that different time slots can have different slot formats (slot format), which can be indicated by a slot format indicator (SFI), which can have up to 256 formats. Different time slot formats include different numbers of upstream symbols, or downstream symbols or flexible symbols.

5GNR supports semi-static and dynamic time slot format configuration. The configuration of the semi-static time slot format is implemented through semi-static signaling instructions. The semi-static signaling instructions are that the base station notifies the user equipment (User Equipment, UE) through radio resource control (Radio Resource Control, RRC) signaling for a period of time. The transmission state of time slots and symbols includes three states: uplink (Uplink, UL), downlink (Downlink, DL), and unknown (unknown). The unknown state may also be referred to as a flexible state, which may be recorded as X, and the UE performs neither a receiving operation nor a sending operation on the symbol corresponding to X. The semi-static signaling is cell-specific, that is, all UEs in the cell receive the semi-static signaling. The dynamic time slot format configuration is implemented through downlink control information (Downlink Control Information, DCI) signaling instructions, that is, NR supports notifying the UE through DCI signaling of a certain time slot format of one or several time slots in a period. The DCI signaling is called a dynamic slot format indicator (SFI), which can be specifically delivered through DCI2_0 signaling. The DCI2_0 signaling can cover the symbol status indicated as unknown in semi-static signaling. In addition, several symbol state combinations of multiple time slots can be predefined in the NR. The table in which the combination is located can be called a UE-specific table (UE specific table). Specifically, the base station can be configured with a group of one or one through the above RRC signaling. The combination of time slot formats on multiple time slots, using the combined entry identifier (entry identifier, entry ID) to indicate the specific time slot format combination, entry ID can be understood as the sequence number of the time slot format combination, the number of entries in the table The maximum can be 512, and the maximum number of slots indicated by each entry can be 256, that is, the respective slots corresponding to the maximum 256 slots. Then, different dynamic SFIs can be used to indicate that the configuration of the corresponding carrier is a combination of time slot formats corresponding to an entry ID in the table.

Based on the above description, since the maximum number of entries in the table can be 512, and the maximum number of slots indicated by each entry can be 256, then the configuration according to the maximum number requires storage space for each UE 256 × 512 = 131072 bytes of storage space. At present, the allowable storage capacity of the on-chip memory is less than or equal to 10Kbyte. When the amount of data is large, it is usually first stored in the on-chip random access memory (Random Access Memory, RAM). When the on-chip RAM is full, it can be stored on the off-chip RAM. Therefore, when storing the table, The table is usually stored in the on-chip memory and the off-chip memory sequentially according to the entry ID. However, the latency required for reading on the on-chip and off-chip memories is different. The off-chip memory usually takes at least a few hundred cycles, and the on-chip memory takes 1 to 10 cycles. According to statistical data, the It takes 1~2us to read an entry from the off-chip memory, which will delay the time of SFI acquisition. In the dynamic SFI notification, the number of entries in the table has been reduced from 4096 to 512. It is impossible to further reduce the number of entries. Therefore, at present, the space required to store the UE-specific table is still very large, and the delay for the UE to read the entry of the table is large, which results in the UE not being able to obtain the time slot format indicated by the SFI in time, thereby affecting the normal operation of the UE.

Summary of the invention

The present application provides a method and device for storing a time slot format, which can solve the problem that the UE has a large delay in reading the entry of the UE-specific table, resulting in the UE being unable to obtain the time slot format indicated by the SFI in time.

In a first aspect, a method for storing a time slot format is provided. The method includes: the device acquires configuration information transmitted by a base station, and the configuration information includes at least one time slot format combination; the device instructs the SFI to adjust at least at least one according to the time slot format received from the base station A storage location for a combination of time slot formats. The device may be a baseband processor (Digital Baseband Processor), a system-on-chip (SoC) chip, a terminal device, or the like. That is to say, the storage location of the slot format combination delivered by the base station according to the present application can be matched according to SFI, so that when the UE reads the configuration information, the delay of reading the slot format combination can be based on the storage time The storage location of the slot format combination varies, and the UE can obtain the slot format combination indicated in the SFI in time. For example, the device counts the sequence number indicating the frequency indicated by the SFI in the time slot format received from the base station, and places the combination of the time slot format corresponding to the sequence number in the first memory or the second memory of the device according to the frequency. The read speed of the first memory is higher than the read speed of the second memory.

In a possible design, in the configuration information, each time slot format combination corresponds to a sequence number, and each time slot format combination includes at least one time slot format identifier; the configuration information is UE specific, time slot format combination That is, an entry, the serial number is the entry ID corresponding to each entry in the UE specific table, and the identifier of the time slot format is the slot format 1, slot format 2, and slot format 3 included in each entry. Entry ID can be indicated by DCI2_0 signaling, DCI2_0 signaling can carry multiple SFI, SFI can be understood as SFI index, an SFI index is an entry ID, DCI2_0 can contain up to 16 SFI indexes, it can also be said that DCI2_0 It can contain up to 16 entry IDs, and each SFI index indicates a slot format combination in the UE specific table.

In a possible design, the device adjusting the storage location of at least one time slot format combination according to the time slot format indication SFI received from the base station includes: the device according to the frequency indicated in the SFI by the first sequence number within a preset time period, The combination of time slot formats corresponding to the first serial number is stored in the first memory or the second memory; wherein the reading speed of the first memory is higher than the reading speed of the second memory. For example, the first memory may be an on-chip memory of the device, and the second memory may be an off-chip memory of the device. For example, the device places the slot format combination corresponding to the serial number in the first memory in the second memory according to the frequency, and places the slot format combination corresponding to the serial number in the second memory in the first memory. Further, for example, according to the frequency counted in the preset time period, the device places the slot format combination corresponding to the sequence number whose frequency is greater than or equal to the first threshold in the second memory, and places the frequency in the first memory The combination of the slot format corresponding to the sequence number less than the first threshold is placed in the second memory. That is, the storage position of the combination of the slot format corresponding to the serial number can be determined according to the comparison between the frequency of the serial number in the SFI and the first threshold, so as to determine the slot format combination corresponding to the serial number with high frequency and the serial number with low frequency Corresponding time slot format combination. In this way, the storage location of the slot format combination corresponding to the serial number is determined according to the frequency indicated by the serial number in the SFI, and the slot format combination corresponding to the serial number that is used more can be distinguished, and these slot format combinations can be placed for reading In the memory with a faster rate, to reduce the delay for the UE to read the entry, that is, the UE can obtain the entry corresponding to the sequence number indicated in the SFI in time.

In a possible design, the range of the first serial number includes at least one serial number. That is, the storage location of the combination of time slot formats corresponding to the serial number can be determined according to the frequency of each serial number, or the storage location of the combination of time slot formats corresponding to the multiple serial numbers can be determined according to the frequencies of multiple serial numbers within the range of a serial number, Relative to adjusting the storage position of the slot format combination for a single sequence number, by shifting the position of the slot format combination corresponding to the sequence number within the range of the sequence number as a whole, rather than performing a separate position for the slot format combination corresponding to each sequence number Transfer can reduce the complexity of time slot format combination transfer. For example, according to the frequency counted in the preset time period, the device places the slot format combination corresponding to the sequence number range where the accumulated value in the second memory is greater than the second threshold in the first memory, and sets the accumulated value in the first memory to less than The corresponding time slot format combination within the sequence number range of the second threshold is placed in the second memory, wherein each sequence number range includes at least one sequence number, and the accumulated value corresponding to any sequence number range corresponds to each sequence number within any sequence number range The sum of frequencies.

In a possible design, the method further includes: the device adjusting the length of the preset time period according to the number of adjustments of the combination of slot formats between the first memory and the second memory. Specifically, when the number of adjustments is high, the preset time period is kept unchanged, and when the number of adjustments is low, the preset time period can be reduced, so as to ensure more accurate capture of the frequency change of the serial number in the SFI. For example, the device adjusts the length of the preset time period according to the transfer rate between the first memory and the second memory; where, if the transfer rate is greater than or equal to the third threshold, the length of the preset time period remains unchanged; if If the transfer rate is less than the third threshold, the length of the preset time period is reduced by the preset step; the transfer rate is the number of times the time slot format combination in the first memory is placed in the second memory and the preset time period. The sum of the number of times the slot format combination in the second memory is placed in the first memory. That is, when the transfer rate is high, the preset time period is kept unchanged, and when the transfer rate is low, the preset time period can be reduced.

In a possible design, before the device adjusts the storage location of at least one slot format combination according to the slot format instruction SFI received from the base station, the method further includes: the device divides the at least one slot format combination into two parts, respectively Stored in the first memory and the second memory. In other words, when the device receives the configuration information, it can first divide the time slot format combination into two parts and store them in the first memory and the second memory, so as to further adjust the serial number corresponding to the serial number according to the frequency of the serial number indicated in the SFI Storage location of time slot format combination. For example, before the device receives the SFI from the base station, the method further includes: the device stores the slot format combination corresponding to the sequence number less than or equal to the fourth threshold in the first memory, and stores the time sequence corresponding to the sequence number greater than the fourth threshold The slot format combination is stored in the second memory. In other words, when the device receives the configuration information, it can first determine the storage location of the combination of the slot format corresponding to each sequence number in the configuration information according to the size of the sequence number and the fourth threshold.

In a second aspect, a method for storing a time slot format is provided. The method includes: the device acquires configuration information transmitted by a base station, and the configuration information includes at least one time slot format combination; the device combines each time slot combination in at least one time slot format combination The first n time slot formats are stored in the first memory, n is a positive integer, and at least one time slot format combination is stored in the second memory, and the read speed of the first memory is higher than that of the second memory. In other words, when storing configuration information, each slot format combination can be truncated and stored in the first memory with a fast reading rate, that is, there is no need to save the full length slot format combination in the second memory The complete configuration information is stored in, so that for the SFI received at the monitoring time, there is the following situation: there is an indication of the same symbol in the SFI obtained at different monitoring times, or the time slot/symbol indicated by the first monitoring time It may receive an indication of the same time slot/symbol at the second listening moment. When the complete information of the configuration information is stored in the second memory, the time slot format combination corresponding to the serial number can be quickly read from the first memory, thereby accelerating the speed at which the device reads the time slot format combination corresponding to the serial number in SFI .

In a possible design, the method further includes: the device determines n according to a monitoring time slot format indicating the monitoring period of the SFI. Due to the small monitoring period, the SFI notified by the base station to the device at each monitoring moment is a sequence number corresponding to the combination of a certain length of time slot format. The SFI obtained at different monitoring moments indicates the same symbol, or The time slot/symbol indicated at a monitoring time may also receive an indication of the same time slot/symbol at the second monitoring time, then n may be determined according to the length of the time slot of the monitoring period to quickly read from the first memory The slot format combination corresponding to each entry.

In a possible design, the time slot length corresponding to the n time slot formats is M monitoring periods, and M is a positive integer. When each monitoring period arrives, the device will monitor the SFI sent by the base station to obtain the slot format combination corresponding to the sequence number indicated in the SFI, so that the truncated length of the configuration information is determined according to the length of the monitoring period, which can effectively avoid the device from missing the SFI. When the SFI is not detected in time, that is, if there is a missed detection, the device can continue to monitor the SFI for the remaining monitoring period of the time slot length. For example, the storage length (slot length) of a slot format combination can be four detection cycles long, so for any missed SFI test, there can be three other earlier SFIs that can cover the missed test station. The combination of slot formats indicated by the affected SFI.

In a possible design, the method further includes: the device determines M according to the probability that SFI is not detected at P consecutive listening moments, and P is a positive integer. That is to say, the device can determine M according to the missed detection of SFI, that is, further determine the value of n that truncates the slot format of the configuration information, so that any missed detection can be covered by the transmission of the monitored SFI at other monitoring moments.

In a possible design, the terminal determining M according to the probability of not listening to SFI at P consecutive listening moments includes: the device determining M according to the probability of not listening to SFI at P consecutive listening moments, and a function that takes probability as a variable. In this way, the M value can be conveniently determined through function calculation to further determine the storage length of the configuration information.

The method includes: a base station determines an order of each sequence number in configuration information according to a slot format indication SFI, and the configuration information includes at least one slot format combination and each slot format Combine the corresponding serial numbers; the base station transmits configuration information to the device according to the sequence of the serial numbers. The device may be a baseband processor, SoC or terminal. Correspondingly, for the device, the time slot format combination corresponding to the first sent serial number can be stored in the order of the serial number transmitted by the base station. Generally, the device is stored in the on-chip memory first, and then stored off-chip when the on-chip memory is full. Memory, the read rate of the on-chip memory is higher than the off-chip memory, then the combination of the slot format stored in the on-chip memory can be quickly read. For example, when the use frequency of the serial number determines the order, the device can quickly read the combination of time slot formats with high use frequency.

In a possible design, the base station determines the sequence of each sequence number in the configuration information according to the slot format indication SFI includes: the base station determines the arrangement of each sequence number according to the frequency indicated by each sequence number in the DCI signaling for indicating SFI order. In this way, when the base station transmits the configuration information, the slot format combination corresponding to the sequence number with a higher frequency can be transmitted before the slot format combination corresponding to the sequence number with a lower frequency, then when the device receives the configuration information, the corresponding The time slot format combination corresponding to the serial number with a high frequency is stored before the time slot format combination corresponding to the serial number with a low frequency. When the device is stored, it is first stored in the memory with a high reading rate and the memory with a high reading rate is stored When it is full, continue to store in the memory with a relatively low reading rate, so that when the device obtains the slot format combination corresponding to the serial number with a high frequency of use, it can be quickly obtained from the memory with a high reading rate, reducing The delay for the device to read the entry corresponding to the entry ID indicated by the SFI.

In a possible design, the sequence number and the slot format combination corresponding to the sequence number are arranged according to the frequency corresponding to the sequence number from large to small; when the base station transmits configuration information to the device, the sequence number with a large frequency and the time slot format corresponding to the sequence number The combination is transmitted before the combination of the sequence number with a small frequency and the slot format corresponding to the sequence number. Correspondingly, when the device stores configuration information, the serial number with a large frequency and the combination of time slot formats corresponding to the serial number are stored before the serial number with a low frequency and the combination of time slot formats corresponding to the serial number. In this way, the combination of the slot format corresponding to the sequence number with a large frequency indicated in the SFI can be quickly read in the memory of the previous memory.

On the basis of the above network architecture, in order to solve the problem that the UE has a large delay in reading the entry of the UE specific table, resulting in the UE not being able to obtain the slot format indicated by the SFI in time, a slot format storage method is provided, such as As shown in Figure 3, including:

301. The base station transmits configuration information to the device. The configuration information includes at least one time slot format combination.

The device here may be a baseband processor, SoC or terminal device. The configuration information may include the above-mentioned UE specific table, and the UE specific table includes multiple sequence numbers, namely, entry IDs, and each entry ID corresponds to a time slot format combination. The configuration information can be delivered to the device through RRC signaling.

302. The device adjusts the storage location of at least one slot format combination according to the SFI received from the base station.

The base station may notify the device of the time slot format of one or several time slots in a period through DCI signaling. The DCI signaling may be called a dynamic SFI indication, and the DCI signaling may specifically be DCI2_0 signaling. The DCI2_0 signaling contains multiple SFI indexes, such as SFI index1, SFI index2, ... and SFI index16, which contains up to 16 SFI indexes, each SFI index is equivalent to the above entry ID, and the device can be based on the DCI2_0 signal Let demodulate a certain entry ID needed to find the UE specific table according to the entry ID to obtain the slot format combination corresponding to the entry ID. The SFI received from the base station described in the full text is the dynamic SFI indication received from the base station, or DCI2_0 received from the base station.

In this way, the device can learn the entry ID based on the SFI received from the base station, and then search for the corresponding slot format combination according to the entry ID, so the adjustment of the storage position of the slot format combination can be adjusted according to the entry ID indicated by the SFI. For example, the storage location of the slot format combination corresponding to the entry ID can be determined according to the frequency indicated by the entry ID in the SFI, instead of directly storing the device in the order of receiving the slot format combination from the base station as in the prior art, without timing The storage location of the slot format combination can be adjusted. The method of adjusting the storage location of the slot format combination according to the SFI in this application can perform matching storage on the slot format combination, thereby affecting the delay of the UE accessing the UE specific table. The UE can obtain the time slot format indicated by the SFI in time.

The following uses the device as a terminal device to further describe the embodiments of the present application.

This application provides a time slot format storage method, as shown in FIG. 4, including:

401. The base station transmits configuration information to the terminal device. The configuration information includes at least one slot format combination and a sequence number corresponding to each slot format combination.

The configuration information may be the above-mentioned UE specific table, the sequence number is the above-mentioned entry ID or SFI index, and one slot format combination (or an entry) is a combination of multiple slot format identifiers corresponding to one entry ID, UE There can be up to 512 time slot format combinations in a specific table.

402. The terminal device divides the configuration information into two parts and stores them in the first memory and the second memory of the terminal, respectively. The read rate of the first memory is higher than the storage rate of the second memory.

Taking the first memory as an on-chip memory and the second memory as an off-chip memory as an example, the terminal device may divide a partial storage area (memory) in the first memory of the chip, and correspond to the serial number in the configuration information that is less than the first threshold The time slot format combination is stored in the divided storage area of the first memory, and the time slot format combination corresponding to the serial number greater than or equal to the first threshold is stored in the second memory. For example, the first threshold is 100, and the time slot format combination corresponding to the sequence number within 100 is stored in the first memory, and the time slot format combination corresponding to the sequence number greater than or equal to 100 is stored in the second memory.

403. The base station sends DCI signaling to the terminal device. The DCI signaling includes SFI, and the SFI is used to indicate the sequence number in the configuration information.

Accordingly, the terminal device needs to obtain the SFI in the DCI signaling when the listening time arrives. The period in which the terminal equipment monitors the DCI signaling is notified by the base station to the terminal equipment through additional RRC signaling.

The DCI signaling may specifically be DCI2_0 signaling, which can carry the SFI of 16 cells at most, that is, 16 SFI indexes or entry IDs. The terminal device may obtain the SFI of the cell to which it belongs according to the received DCI signaling.

404. The terminal device counts the frequency indicated by the first serial number in the SFI within a preset time period. If the frequency indicated by the first serial number in the SFI is greater than or equal to the second threshold, the slot format corresponding to the first serial number is placed in combination. In the first memory, if the frequency indicated by the first serial number in the SFI is less than the second threshold, the slot format combination corresponding to the first serial number is placed in the second memory.

The range of the first serial number includes at least one serial number.

If the range of the first serial number indicates a serial number, that is to say, step 404 can be understood as: the terminal device counts the frequency indicated by each serial number in the SFI within a preset time period, if any of the serial numbers indicates a frequency greater than or equal to Equal to the second threshold, the slot format combination corresponding to any serial number is placed in the first memory, and if the frequency indicated by the SFI in the SFI is less than the second threshold, the slot format corresponding to any serial number The combination is placed in the second memory. For example, the entry ID carried in the DCI2_0 signaling in the preset time period is 1, 2, 122, and 134, where the entry ID of 122 has the frequency indicated 5 times in the preset time period, if the second threshold is 3, the slot format combination corresponding to the entry ID of 122 is determined to be placed in the first memory, if the slot format combination corresponding to the entry ID of 122 is already stored in the first memory when the configuration information is stored in step 402 , The slot format combination corresponding to the entry ID of 122 does not need to adjust the storage location. If the slot format combination corresponding to the entry ID of 122 is stored in the second memory when the configuration information is stored in step 402, it is necessary to change The slot format combination corresponding to the entry ID of 122 is transferred from the second memory to the first memory.

If the first serial number indicates at least two serial numbers, that is to say, during the execution of step 404, when the terminal device performs frequency statistics corresponding to the above entry ID, it is not for each entry, or for each slot format The combination counts statistics, but counts the entry IDs in a certain range. Each range here can include multiple entry IDs. For example, the entry ID of 1-10 is one range, and the entry ID of 11-20 is another range. Then step 404 can be understood as: the terminal device counts the frequency indicated in the SFI for each sequence number range within the preset time period, and the frequency within any sequence number range is the sequence number within the sequence number range indicated in the SFI within the preset time period The accumulated value of the frequency of the frequency; the terminal device places the slot format combination corresponding to the sequence number within the sequence number range of the accumulated value of the second memory greater than or equal to the second threshold in the first memory, and the accumulated value in the first memory is less than the second The combination of the slot format corresponding to the sequence number within the threshold sequence number range is placed in the second memory.

Among them, the range can be divided in the order of combination of time slot formats, and the divided range is recorded as range1, range2, ..., range, etc., and m is a positive integer. For example, range1 includes the combination of slot format corresponding to entry ID1-10, range2 includes the combination of slot format corresponding to entry ID11-20... Or, the division of range can be based on the correlation of the combination of slot format, for example, entry The combination of time slot formats with IDs 1, 3, 9 and 11 has relevance and is classified as range1, and the combination of time slot formats with IDs 2, 4, 6, 8 and 12 has relevance and is classified as range2 . In this way, when performing the frequency statistics of the entries in a certain range, the frequency corresponding to each entry in the range is accumulated. In this way, when the time slot format combination transfer between the first memory and the second memory is performed, the transfer is performed in the range unit instead of the transfer for each entry, which can reduce the space between the first memory and the second memory The complexity of the time slot format combination transfer.

405. The terminal device adjusts the length of the preset time period according to the adjustment times of the combination of the slot format between the first memory and the second memory.

It should be noted that, if the first memory is not full during the execution of step 404, step 405 may not be executed, and if the first memory is full during the execution of step 404, step 405 is executed.

Step 405 can also be understood as: the terminal device adjusts the length of the next preset time period according to the number of adjustments of the combination of the slot format between the first memory and the second memory in the current preset time period.

The number of adjustments can also be understood as the transfer rate. The transfer rate is the number of times the slot format combination in the first memory is placed in the second memory and the time slot format combination in the second memory is placed in the first period of time. The sum of the times of a memory. If the transfer rate is greater than or equal to the third threshold, the length of the preset time period is kept unchanged; if the transfer rate is less than the third threshold, the length of the preset time period is reduced by the preset step, which can ensure more accurate SFI indicates the change in frequency of capture.

Therefore, in this embodiment, the storage location of the slot format combination of the serial number is determined according to the different use frequencies of the serial number, the slot format combination can be stored in a matching manner, and the slot format combination with a high use frequency can be stored at the reading speed The high first memory, that is, the manner of determining the storage location of the slot format combination according to historical information can accelerate the speed at which the terminal device reads the slot format combination indicated by the SFI.

An embodiment of the present application also provides a method for storing a slot format, as shown in FIG. 5, including:

501. The base station determines the sequence of each sequence number in the configuration information according to the slot format instruction SFI. The configuration information includes at least one slot format combination and a sequence number corresponding to each slot format combination.

The base station may determine the order of each entry ID for the next transmission of configuration information according to the frequency indicated by each entry ID in SFI for a period of time. The entry ID with a higher frequency is ranked before the entry ID with a lower frequency.

502. The base station transmits configuration information to the terminal device according to the sequence of the serial numbers.

When the base station transmits configuration information, the order of the combination of the entry ID and the slot format corresponding to the entry ID is arranged in descending order of the frequency indicated by the entry ID in the DCI signaling as the SFI index, so that entries with a high frequency can be used The time slot format combination corresponding to the ID is transmitted before the low frequency entry ID time slot format combination, then when the terminal device receives the configuration information, the corresponding sequence number of the first transmission is stored in the order of the entry ID transmitted by the base station Time slot format combination, so that the time slot format combination corresponding to the entry ID with a high frequency can be stored before the time slot format combination corresponding to the entry with a low frequency, and when the terminal device is stored, it is stored in the terminal device first When the memory with a high reading rate is full, the memory with a high reading rate is full, and then continue to store in the memory with a relatively low reading rate, so that when the terminal device obtains the slot format combination corresponding to the entry ID with a high frequency of use , It can be quickly obtained from the memory with a high reading rate, which reduces the latency of the entry corresponding to the entry ID indicated by the SFI.

Generally speaking, the terminal device is stored in the on-chip memory first, and then stored in the off-chip memory when the on-chip memory is full. The read rate of the on-chip memory is higher than the off-chip memory, then the time slot format stored in the on-chip memory first The combination can be quickly read. Since the use frequency of the serial number determines the transmission sequence, the device can quickly read the combination of time slot formats with high use frequency from the on-chip memory.

An embodiment of the present application also provides a method for storing a slot format, as shown in FIG. 6, including:

601. The terminal device receives configuration information transmitted by the base station. The configuration information includes at least one slot format combination and a sequence number corresponding to each slot format combination.

602. The terminal device determines the storage location of the slot format combination corresponding to the sequence number indicated by the SFI according to the number of bits occupied by the sequence number indicated by the SFI in the DCI signaling in the DCI signaling.

For example, when receiving DCI2_0 signaling, the terminal device can obtain the number of bits occupied by each entry ID. If the number of bits occupied by the entry ID in the DCI2_0 signaling is less than or equal to the fourth threshold, and the slot format combination corresponding to the entry ID is stored in the second memory, the terminal device may store the slot format corresponding to the entry ID in the second memory The combination is placed in the first memory; if the number of bits occupied by the entry ID in the DCI2_0 signaling is greater than the fourth threshold, and the corresponding slot format combination in the DCI2_0 signaling is stored in the first memory, the terminal device stores the first memory The combination of the slot format corresponding to the entry ID is placed in the second memory. The reading speed of the first memory is higher than that of the second memory. For example, the first memory is an on-chip memory, and the second memory is an off-chip memory.

For example, the fourth threshold may be 8 bits or other values, which is not limited in this application. The fourth threshold value is 8bit, because the DCI2_0 payload size is 128bit, which is equal to 16 cells times the 8bit occupied by the entry ID assigned to each cell. Therefore, when the base station actually transmits DCI2_0 signaling, each The number of bits occupied by an entry ID is usually within 8 bits. Therefore, an entry ID greater than 8 bits and the corresponding time slot format combination can be placed in the second memory.

In this way, the entry ID with a small number of bits and the corresponding time slot format combination will be stored in the first memory with a high reading rate. The first memory may also store more time slot format combinations, so that reading the SFI indication The delay of the time slot format combination will also be reduced.

In addition, in the prior art, the monitoring period of SFI is relatively small, and there may be 1, 2, 4, 5, 8, 10, and 20 time slots. The SFI detected in the DCI2_0 detected at each monitoring time is usually an indication of a combination of time slot formats of a certain length. The length can be up to 256 time slots. For repeated or overlapping notifications at different monitoring times For time slot transmission, the terminal device side expects consistent indication information, that is, the base station usually indicates consistent information. Therefore, each entry indication is redundant, and the terminal device does not need to save the full-length SFI indication when storing configuration information. Slot format combination, the slot format combination can be shortened and saved to reduce storage space consumption.

Therefore, an embodiment of the present application also provides a method for storing a slot format, as shown in FIG. 7, including:

701. The terminal device obtains configuration information transmitted by the base station, where the configuration information includes at least one slot format combination.

702. The terminal device stores the first n slot formats of each slot combination in at least one slot format combination in the first memory, where n is a positive integer, and stores at least one slot format combination in the second memory. The reading speed of one memory is higher than that of the second memory.

It can be understood that, when storing the contents of Table 2, the terminal device shortens the contents of Table 2 vertically, and takes the slot format corresponding to each entry slot format 1 to slot format, that is, takes the combination of each slot format The first n time slot formats of the, the intercepted time slot format are stored in the first memory with a faster reading speed, and the complete storage of Table 2 is performed in the second memory with a slower reading speed than the first memory , That is, the information in the second storage as backup information. It should be noted that when truncating and storing each entry here, it can be truncated for each entry in Table 2, or it can be truncated for the entry corresponding to the higher frequency entry ID in the above embodiment short.

In this way, under the condition that the complete information of Table 2 is stored in the second memory, if the DCI2_0 signaling sent by the base station is subsequently received, the time slot format combination of each entry can be quickly obtained from the first memory, thereby Accelerate the speed of acquiring the combination of slot format indicated by SFI.

For the determination of the above value of n, in a possible implementation, the terminal device may determine n according to the monitoring period of monitoring SFI. Specifically, the time slot length corresponding to the n time slot formats is M listening periods, and M is a positive integer. This is considering that the terminal device may have missed detections while monitoring the SFI, so for any missed detection, there is an earlier n-1 detected SFI that can cover the slot affected by the missed detection.

Further, the terminal device may determine M according to the probability that SFI is not detected at P consecutive listening moments, and P is a positive integer. The probability here can be understood as: the number of times SFI is not monitored at P consecutive monitoring moments.

Since the above configuration information may be semi-static, after receiving the configuration information last time, the terminal device may determine the M according to the probability that the SFI is not monitored for P consecutive monitoring moments after receiving the configuration information last time. The configuration information is truncated and stored.

The terminal device determining M according to the probability of not monitoring SFI at the P consecutive monitoring moments may include: the terminal device determining M according to the probability of not monitoring the SFI at the P consecutive monitoring moments and a function using the probability as a variable. For example, when the probability is denoted by q, the function can be expressed as: M=F(q), and F(q) can be a linear or nonlinear function.

Among them, when determining n, if the probability is recorded as q, you can first determine whether the probability is greater than or equal to a preset threshold, if it is greater than the preset threshold, then determine M according to the probability and the function, if not If it is greater than the preset threshold, n can be directly determined according to an algorithm and M, for example, n is M monitoring periods. If the probability is greater than or equal to the preset threshold, the slot length corresponding to n slot formats is expressed as M*monitoring period, M*monitoring period>F(q), if the function is a linear function, such as F (q)=a*q+b, where a and b are preset parameter values, if the function is a non-linear function, for example F(q)=a*㏒(q)+b, where a and b are pre- Set the parameter value.

In other words, the terminal device determining M based on the probability of not listening to SFI at P consecutive monitoring moments can also be understood as: how long the terminal device calculates that X will miss a DCI2_0, for example, for a missed detection, time X is recorded as time X1 For two consecutive missed tests, the time X is recorded as X2. Then, you can determine n according to X, for example, the function of X and n is expressed as n=F(X), so that the storage capacity of the first memory is reduced from 512*256Bytes to 512*nBytes, n can be 20, 40 And 60 and so on.

Taking the SFI monitoring period as 20 as an example, first determine the probability of SFI missed detection;

1) If SFI is monitored at all P consecutive monitoring moments, then the probability of not monitoring SFI is zero, or if there is no continuous missed detection, the storage length corresponding to the configuration information can be set to at least M*20≥20 *2, that is M≥2;

2) If there are no consecutive missed detections at consecutive P monitoring moments, or that the probability of not monitoring SFI at P monitoring moments is less than the preset threshold, then the storage length corresponding to the configuration information can be set to at least M*20≥* 20 (P+1), that is M≥(P+1);

3) If there are consecutive missed detections at consecutive P monitoring moments, or the probability of not monitoring SFI at P monitoring moments is greater than or equal to the preset threshold, and it is expected that any missed detection will be covered y times by other SFI transmissions , Then you can set the storage length corresponding to the configuration information M*20≥20*(P+y), that is, M≥(P+y).

For example, as shown in Figure 8, the storage length corresponding to an entry, or the storage length corresponding to a slot format combination is four monitoring periods long, then, for any missed detection, in fact there are other changes The early three SFIs can cover the slots affected by this missed inspection.

As shown in Figure 9, the storage length corresponding to an entry is four monitoring cycles long. If two consecutive missed detections occur, some of the slots will be caused, that is, the slots affected by the second missed detection can only be affected by the previous two SFI coverage. For the first missed test, in fact there are three earlier SFI instructions that can cover the slots affected by these missed tests.

As shown in Figure 10, the storage length corresponding to an entry can be as long as five monitoring cycles. If two consecutive missed checks occur, for any one missed check, in fact, there are other three earlier SFIs that can cover these leaks. Check the affected slots.

It should be noted that when the base station updates the monitoring period, that is, if the value of one monitoring period changes to the value of another monitoring period, the larger monitoring period value of the two monitoring periods can be used as a reference during the change , In case the sudden update prevents the entry in the first memory from satisfying the length of the listening period.

For example, when the value of the monitoring period is 1 slot, the length of the entry storage slot can be set to 1*m, for example, m=20. Here, m=20 is set because the difference between 1 and 20 is large, in order to prevent the monitoring period from mutating from 1 slot to 20 slots;

When the value of the monitoring period is 2 slots, the length of the entry storage slot can be set to 2*m, where 2*m≥20; for example, m=10. The setting of m=10 here is due to the large difference between 2 and 10, to prevent the monitoring period from mutating from 2 slots to 20 slots;

When the value of the monitoring period is 4 slots, the length of the entry storage slot can be set to 4*m, where 4*m ≥ 20; for example, m=5. The setting of m=5 here is due to the large difference between 4 and 20, in order to prevent the monitoring period from mutating from 4 slots to 20 slots;

When the value of the monitoring period is 5 slots, the length of the entry storage slot can be set to 5*m, where 5*m≥20; for example, m=8. The setting of m=8 here is due to the small difference between 5 and 20, to prevent the monitoring period from mutating from 5 slots to 20 slots;

When the value of the monitoring period is 10 slots, the length of the entry storage slot can be set to 10*m, where 10*m≥20; for example, m=4. The setting of m=4 here is because the difference between 10 and 20 is small, in order to prevent the monitoring period from mutating from 10 slots to 20 slots.

In this way, the embodiment of the present application can determine the storage slot length of the entry corresponding to the UE specific table in the configuration information according to different monitoring periods, which can ensure that the complete information of the UE specific table is stored in the second memory with a slow reading speed Next, the configuration corresponding to each entry can be quickly acquired from the first memory with a faster reading speed, thereby accelerating the acquisition speed of the combination of slot formats of the SFI.
