Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method for adjusting a slot interval and a communications device.
Background
In Rel-15 defined by the third generation mobile communication standardization organization (3rd generation partnership project,3GPP), when a network device, such as a base station, schedules a data channel of a terminal, the network device first transmits scheduling information, through which the data channel of the terminal is scheduled, for example, the PDSCH of the terminal is scheduled by the scheduling information of a physical downlink shared channel (physical downlink shared channel, PDSCH) transmitted through a physical downlink control channel (physical downlink control channel, PDCCH), or the PUSCH of the terminal is scheduled by the scheduling information of a physical uplink control shared channel (physical uplink shared channel, PUSCH) transmitted through the PDCCH, where the scheduling information may indicate transmission parameters of the data channel, such as: and the time domain resource position of the data channel, and the like, and the terminal can receive the data channel at the time domain resource position of the data channel according to the indication of the scheduling information.
In the scheduling process, the network device needs to configure one or more sets of optional values of the minimum available scheduling interval for the terminal, for example, the set of minimum available scheduling interval may include K0 and/or K2, and the terminal may determine a time slot position of a data channel scheduled by the PDCCH according to the configured minimum available scheduling interval, and receive the PDSCH or transmit the PUSCH at the determined time slot position.
In a New Radio (NR) system, the network device may select any value from the smallest available scheduling interval to configure to the terminal. However, if the minimum available scheduling interval configured for the terminal is too large, the data transmission delay between the network device and the terminal is too large, and the client delay is affected; if the minimum available scheduling interval configured for the terminal is too small, resource waste may result. Therefore, how to reasonably configure the minimum available scheduling interval for the terminal becomes a problem to be solved.

Detailed Description
Before describing embodiments of the present application, terms related to the embodiments of the present application will be explained:
a physical downlink control channel (physical downlink control channel, PDCCH) is mainly used for carrying downlink control information (downlink control information, DCI), where the DCI may include common control information (such as system information, etc.) and user-specific information (such as downlink resource allocation indication, uplink scheduling, random access response, uplink power control parameters, etc.), etc. The PDCCH may schedule data channels through DCI it carries, such as: the DCI may be used to indicate transmission parameters of a data channel (e.g., a time-domain resource location of the data channel, etc.), where before the data channel is transmitted, the network device may send the PDCCH to the terminal, and after the terminal receives the PDCCH, the terminal may demodulate the DCI in the PDCCH and then receive or send the data channel at the time-domain resource location indicated by the DCI. Further, the PDCCH may also indicate a time domain resource location of a channel state information reference signal (channel state information reference signal, CSI-RS) through DCI carried by the PDCCH to trigger transmission of aperiodic (non-periodic) CSI-RS.
A data channel, which may be used to carry data. The 3GPP protocol divides the data channels into: a physical uplink data channel (physical uplink shared channel, PUSCH) (or referred to as an uplink data channel) and a physical downlink data channel (physical downlink shared channel, PDSCH) (or referred to as a downlink data channel). Wherein, PUSCH is used to carry data (or referred to as uplink data) sent from a terminal to a network device, and PDSCH is used to carry data (or referred to as downlink data) sent from a network device to a terminal.
The minimum available scheduling interval may refer to a minimum time slot difference between a time slot occupied by a physical downlink control channel (physical downlink control channel, PDCCH) and a time slot occupied by a data channel scheduled by the PDCCH, and the time slot occupied by the PDCCH may be the same as or different from the time slot occupied by the data channel scheduled by the PDCCH. The data channels may include a physical uplink data channel (physical uplink shared channel, PUSCH), a physical downlink data channel (physical downlink shared channel, PDSCH), which may be referred to as an uplink data channel, and a PDSCH, which may be referred to as a downlink data channel. Wherein, the minimum schedulable interval may include a K0 value, a K1 value, and a K2 value.
In the 3GPP protocol, the time slot interval between the time slot occupied by the PDCCH and the time slot occupied by the PDSCH scheduled by the PDCCH is indicated by the K0 value, where the K0 value has a value set, for example, the value set of K0 may include {0,1, … …,32}. And indicating the time slot interval between the time slot occupied by the downlink PDSCH and the time slot occupied by the corresponding hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) feedback through the K1 value.
Among them, HARQ feedback includes Acknowledgement Characters (ACKs) and NACKs (Non-ACKs). K1 may refer to a slot interval between PDSCH and HARQ ACK or NACK. One PDSCH corresponds to one ACK or NACK. If the terminal receives the PDSCH, the terminal can feed back the ACK after the K1 interval; if the terminal does not receive the PDSCH, a NACK may be fed back after a K1 interval.
The value of K1 has a value set, for example, the value set of K1 may include {0,1, … …,15}. The K2 value indicates the time slot interval between the time slot occupied by the PDCCH and the time slot occupied by the PUSCH scheduled by the PDCCH, and the value of K2 has a value set, for example, the value set of K1 may include {0,1, … …,32}. The larger the values of K0, K1, and K2, the larger the corresponding time slot interval, which may result in longer data transmission time between the network device and the terminal.
The network device may configure a plurality of sets of slot intervals for the terminal. For example, the network device may configure the 32 sets of slot intervals described above for terminal configuration. When the network equipment and the terminal carry out data transmission, the network equipment can arbitrarily select one set of time slot intervals from the 32 sets of time slot intervals for the terminal to use. However, in practical applications, only a partial slot interval of the 32 sets may be used, for example, the partial slot interval may be 0, 2, 4, 6, 16, etc. That is, the network device is configured to the terminal in 32 sets of time slot intervals, only 5 sets of time slot intervals are used, and thus waste of resources is caused. Meanwhile, in some cases, for example, the minimum available scheduling interval configured by the network device for the terminal is too large, which may cause too large data transmission delay between the terminal and the network device, so that the requirement of the user cannot be met.
Based on the technical problem, the embodiment of the application provides a method for adjusting a time slot interval, which comprises the following steps: for a target network slice with subscription information comprising a time slot interval, the network equipment acquires a plurality of data transmission times of the target network slice, and adjusts the time slot interval of at least one terminal under the target network slice under the condition that the plurality of data transmission times are not in a preset condition, so that the data transmission time of the target network slice meets the preset data transmission time. Furthermore, the data transmission delay of the target network slice can be reduced, and the requirements of users are met.
Further, in the embodiment of the present application, the network device may configure a part of the total slot intervals to the terminal. Based on the method provided by the embodiment of the application, for the adjusted multiple terminals, the K1 value of each terminal may be different, and if the K1 value of the terminal is 0, 2, 4 or 6. Some terminals have K1 values of 1, 3, 5, and 6. Some terminals may take on only one value, such as 32, for K1. The K1 values of some terminals may be all K1. Thus, the K1 value of each terminal may be a customized configuration. Thus, resources are saved.
In the embodiment of the present application, the network slice is used as granularity for division, and with the development of the communication technology, other resource blocks may be used as granularity for division, which is not limited.

Fig. 3 provides a method for adjusting a slot interval according to an embodiment of the present application, as shown in fig. 3, where the method includes:
in step 301, the network device determines that the subscription information of the target network slice includes a slot interval.
The network device may be the network device in fig. 1. The target network slice may be network slice 1 in fig. 1.
The subscription information may refer to agreement information signed between a user of the network slice and an operator. For example, the subscription information may include one or more of transmission bandwidth, data transmission delay, and slot interval when the user performs data transmission with the network device through the network slice using the terminal.
For example, the network device may store subscription information of a plurality of network slices in advance, and the network device may query the subscription information of the target network slice from the subscription information of the plurality of network slices according to the identification of the target network slice. Or, the network device may also obtain the subscription information of the network slice from the management system of the operator according to the identifier of the target network slice.
It should be noted that, in the case that the subscription information of the target network slice does not include the time slot interval, the time slot interval configured by the network device for all the terminals under the network slice may be a preset value. In the case where the subscription information of the target network slice includes a slot interval, the network device may configure the slot interval in the subscription information for all terminals under the target network slice. That is, the terminal under the target network slice has a high requirement for low-latency data transmission, and the network device needs to adjust the time slot interval of the terminal under the network slice where the subscription information includes the time slot interval.
Step 302, the network device obtains a plurality of data transmission times carried by the target network slice according to a preset time period.
The data transmission time refers to the transmission time of data between the network device and the terminal. The data transmission time may include an uplink data transmission time and a downlink data transmission time. The uplink data transmission time refers to a difference between a time when the terminal transmits uplink data to the network device and a time when the network device receives the uplink data, for example, the uplink data transmission time may be a time between an uplink transmission PDCCH of the data and a time when the uplink data is received. The downlink data transmission time refers to a difference between a time when the network device transmits downlink data to the terminal and a time when the terminal receives the downlink data, for example, the downlink data transmission time may be a time between a downlink transmission PDCCH for the data and a received HARQ ACK.
Alternatively, the uplink data transmission time may be a difference between a time when the network device transmits the PDCCH and a time when the network device successfully parses the PUSCH. For example, the terminal receives the PDCCH from the network device at slot 0. And after K2, the terminal transmits the PUSCH to the network equipment. If the first (i.e., initial) PUSCH parsing by the network device is not successful, the network device schedules the first retransmission PUSCH (i.e., retransmission) after a further time period of Ttime1 (which depends on the algorithm decision of the network device), such as slot 0+t. If the network device successfully analyzes the PUSCH through the retransmission, the time of Ttime1+K2+K2 is equivalent to the time when the network device actually receives the PUSCH for the PDCCH. That is, the downstream data transmission time may be ttime1+k2+k2.
If the network device does not successfully analyze the PUSCH through the retransmission, a second retransmission is needed. The network device also schedules a second retransmission of PUSCH after a number of times Ttime2 have elapsed, which time depends on the algorithmic decision of the network. If the second retransmission is successful, then it is equivalent to actually receiving for this PDCCH to the network PUSCH passed Ttime1+K2+K2+Ttime2+K2 time. That is to say, the downlink transmission time may be Ttime1+K2+K2+Ttime2+K2. If the second retransmission still fails, continuing the retransmission until the network device successfully parses the PUSCH.
The downlink data transmission time may also refer to a scheduling time of the downlink PDCCH and a time when the terminal determines that the PDSCH is received. For example, for PDSCH corresponding to downlink PDCCH scheduling K0 interval in slot 0, if the terminal does not receive the first PDSCH in K0 time, the terminal may send HARQ NACK after k0+k1 interval to indicate that PDSCH is not received and retransmission by the network device is required. After the network device receives the HARQ NACK from the terminal, the PDCCH corresponding to the retransmission may be sent after Ttime1 (the time depends on the algorithm decision of the network), so that the PDSCH corresponding to the first retransmission may be sent after k0+k1+ttime1+k0, then the HARQ NACK or ACK corresponding to the PDSCH for this retransmission may be sent after k0+k1+ttime1+k0+k1, only when the ACK is sent, the difference statistics may be ended, and if the NACK is sent, the statistics may be continued by analogy. For example, after k0+k1+ttime1+k0+k1, the terminal determines that the PDSCH is received, and then the terminal transmits HARQ ACK to the network device. Upon receiving the HARQ ACK from the terminal, the network device may determine that the downlink data transmission time is k0+k1+ttime1+k0+k1.
For example, the network device may acquire transmission times of a plurality of data packets in the target network slice in a time period, and obtain the data transmission time of the target network slice according to the transmission times of the plurality of data packets.
The network device may monitor the data transmission time of the target network slice according to the preset time period, and once the monitored data transmission time of the target network slice does not meet the preset threshold, the network device may execute step 303 described below. The size of the preset time period may be set as required, for example, may be 10 minutes, 30 minutes, 1 hour, etc., without limitation.
In one example, the network device may be preconfigured with a timer whose set time is a preset time period. When the set time of the timer arrives, the network device may be triggered to perform this step.
In another example, the network device may also adjust the time period, for example, if the network device detects that the signal quality of the current period is unstable or is lower than the preset signal strength, the network device may shorten the time period, for example, may subtract a preset value from the time period, where the magnitude of the preset value may be set as required, and is not limited.
Step 303, if the plurality of data transmission times do not meet the preset condition, the network device adjusts the time slot interval of at least one terminal under the target network slice, so that the data transmission time of the target network slice meets the preset data transmission time.
Wherein the slot interval may also be referred to as the minimum available scheduling interval. The description of the minimum available scheduling interval may refer to the above description, and will not be repeated here. The time slot interval of at least one terminal is the time slot interval included in the subscription information.
The terminal may be any terminal in fig. 1, for example, may be terminal 1 or terminal 2 in fig. 1, and is not limited.
The preset data transmission time may refer to a data transmission time between the terminal and the network device. For example, the preset data transmission time may be smaller than the data transmission time in the subscription information of the target network slice. The preset threshold can also be set according to the needs, and is not limited.
The preset condition is used for triggering the network equipment to adjust the time slot interval of the terminal. The preset condition may include the mean and/or variance satisfying a preset value. For example, the network device may obtain a plurality of data transmission times for a current period of the target network slice and calculate a mean and variance of the plurality of data transmission times. The network device may determine whether the plurality of data transmission times satisfy a preset condition according to an average value and/or a variance of the plurality of data transmission times. Furthermore, the network device may adjust the time slot interval of the current period of at least one terminal under the target network slice, so that the data transmission time of the target network slice in the next period satisfies the preset time. For example, the network device may reduce the value of at least one of K0, K1, K2 of the at least one terminal to reduce the data transmission time of the target network slice in the next cycle. Thus, the network device can periodically detect the data transmission time of the target network slice, and if the data transmission time of the target network slice does not meet the preset condition, the time slot interval of at least one terminal under the target network slice is adjusted.
Based on the technical solution of fig. 3, for a network slice in which subscription information includes a slot interval, the network device may adjust the slot interval configured by at least one terminal under the network slice according to a plurality of data transmission times of the network slice, so that a transmission delay between the adjusted terminal and the network device satisfies a preset data transmission time. Therefore, the network equipment can adjust the time slot interval configured by the terminal based on the data transmission time of the network slice, and the adjusted data transmission time can meet the requirements of users.
In one possible implementation manner of fig. 3, in a method provided in an embodiment of the present application, step 302 may specifically include: the network device may adjust the slot intervals configured by the plurality of terminals under the target network slice based on an average of the plurality of data transmission times and/or a variance of the plurality of data transmission times.
This possible implementation is described below.
1. If the average value of the plurality of data transmission times is smaller than or equal to the first preset value, the network device can reacquire the plurality of data transmission times of the target network slice, and initialize the counter.
2. If the average value of the plurality of data transmission times is larger than the first preset value and the variance of the plurality of data transmission times is smaller than or equal to the second preset value, the network device adjusts the time slot intervals of all the terminals under the target network slice.
3. If the average value of the plurality of data transmission times is larger than the first preset value and the variance of the plurality of data transmission times is larger than the second preset value, the network equipment adjusts the time slot interval configured by the terminal with the channel quality lower than the preset value in the plurality of terminals.
The first preset value and the second preset value may be set as required, for example, the first preset value may be 11, and the second preset value may be 13, which is not limited.
It should be noted that, if the average value of the multiple data transmission times of the target network slice is greater than the first preset value, but the variance of the multiple time transmission times is smaller than the second preset value, this means that all the terminal values in the target network slice have some terminals with poor channel quality, and the network device only needs to adjust the time slot intervals of the terminals with poor channel quality. If the average value of the multiple data transmission times of the target network slice is greater than the first preset value and the variance of the multiple time transmission times is greater than the second preset value, this means that the time delay of all terminals of the target network slice is poor, and in this case, the network device needs to adjust the time slot intervals of all terminals under the target network slice.
Further, the network device may be provided with a counter, where the counter is configured to count a number of periods when the data transmission time of the target network slice is less than the preset time. If the data transmission time in one period of the target network slice is less than the preset time, the counter may be triggered to increment by a first value (e.g., 1 may be added). For example, the network device may send a first instruction to the counter when the network device detects that the data transmission time in the current period is greater than the preset time, where the first instruction is used to instruct the counter to increment by a first value to obtain a first cumulative value, where the first cumulative value is used to indicate the period and a number of at least one period before the period. The data transmission time of the target network slice in the at least one period is smaller than the preset time.
In one example, when the timer triggers the network device to start detecting the data transmission time of the current period, if the first accumulated value of the current period of the counter is T, it is indicated that the data transmission time of the target network slice in consecutive T periods before the current period is less than the preset time. For example, if the current period is i, the data transmission time from the i-th period to the i-1 th period of the target network slice is less than the preset time. For example, when the current period is 5 and t=3, it indicates that the data transmission time from the 2 nd period to the 4 th period of the target network slice is less than the preset time.
It should be noted that, if the network device monitors that the data transmission time of the target network slice in the current period is greater than or equal to the preset time, the network device may trigger the initialization of the counter, that is, the counter is cleared to 0. In this case, the counter may re-count the number of periods in which the data transmission time of the target network slice is less than the preset time.
The following describes the above 3 adjustment modes with reference to specific examples:
in example 1, as shown in fig. 4, taking a plurality of data transmission times of a target network slice as downlink data transmission times, the accumulated value of the counter is exemplified as j. When the network equipment starts to monitor the downlink data transmission time of the current period, the counter is increased by a first value to obtain a first accumulated value j. The network device may perform the following steps S1 to S3.
S1, if the average of a plurality of downlink data transmission time is smaller than or equal to a preset value 1, initializing a counter by the network equipment.
S2, if the average value of the plurality of downlink data transmission times is smaller than a preset value 1, and the variance of the plurality of downlink data transmission times is larger than a preset value 2, the network device can subtract j from any one of K0 and K1 of the first terminal. The first terminal is a terminal with channel quality lower than a preset value in a plurality of terminals under the target network slice. The network device may subtract j from K0 of the first terminal, or may subtract j from K1, without limitation.
For example, the slot interval k0=n, k1=m of the first terminal, the network device determines k0=n-j, k1=m, or k0=n, k1=m-j of the first terminal in a period subsequent to the current period.
It should be noted that, if the value of K0 minus j is smaller than 0, the network device may maintain K0, and preferably subtract j from K1; if the value of K0 minus j is equal to 0, then the network device may adjust the value of K1 at a later period.
S3, if the average value of the plurality of downlink data transmission times is larger than a preset value 1, and the variance of the plurality of downlink data transmission times is smaller than or equal to a preset value 2, the network device can subtract j from K0 and K1 of all terminals of the target network slice.
In example 2, as shown in fig. 5, taking a plurality of data transmission times of a target network slice as uplink data transmission times, the cumulative value of the counter is m as an example. When the network equipment starts to monitor the uplink data transmission time of the current period, the counter is increased by a first value to obtain a first accumulated value m. The network device may perform the following steps S4 to S6.
And S4, if the average of the plurality of uplink data transmission time is smaller than or equal to a preset value 3, initializing a counter by the network equipment.
S5, if the average value of the plurality of uplink data transmission times is smaller than a preset value 3, and the variance of the plurality of uplink data transmission times is larger than a preset value 4, the network device can subtract m from any one of K0 and K1 of the first terminal. The first terminal is a terminal with channel quality lower than a preset value in a plurality of terminals under the target network slice. The network device may first subtract m from K2 of the first terminal.
For example, the slot interval k2=a of the first terminal, the network device determines k2=a-m of the first terminal in a period one after the current period.
And S6, if the average value of the plurality of uplink data transmission times is larger than a preset value 3, and the variance of the plurality of uplink data transmission times is smaller than or equal to a preset value 4, the network equipment can subtract m from K2 of all terminals of the target network slice.
In another possible implementation manner of fig. 3, in a method provided in an embodiment of the present application, before step 301, the method may further include: the network device determines whether the subscription information of the target network slice includes a time interval.
If the target network slice does not have a corresponding time interval, the network device sets the time slot intervals of the plurality of terminals under the target network slice to a preset value, for example, the network device may set the K0 value of each terminal to 32, the K1 value to 15, and the K2 value to 32. If the target network slice has a corresponding time interval, the network device may set the time slot intervals of the plurality of terminals as the time slot intervals in the subscription information.
It should be noted that, for a network slice without a slot interval in the subscription information, this means that a terminal under the network slice has a lower requirement for delay. The network device may set the slot interval of the terminal under the network slice to a default value, where the default value may be preset, for example, taking the slot intervals of K0 and K1 as an example, the network device may set K0 and K1 of the terminal under the network slice to maximum values, for example, K0 is set to 32, and K1 is set to 15, so as to meet the basic requirement of the user.
The following describes in detail the technical solution provided in the embodiment of the present application with reference to fig. 1:
as shown in fig. 6, another method for adjusting a slot interval is further provided in the embodiments of the present application, including:
step 601, the network device determines whether the subscription information of the target network slice includes a slot interval.
If not, the network device performs step 602; if so, the network device performs steps 603 to 607.
Step 602, the network device sets the time slot intervals of all terminals under the target network slice to a preset value.
Specifically, the description of this step may refer to the second possible implementation manner of fig. 3, which is not described herein.
In step 603, the network device sets the time intervals of all terminals under the target network slice as the time slot intervals in the subscription information.
Step 604, the network device obtains a plurality of data transmission times of the target network slice, and triggers the counter to increment a first value.
The plurality of data transmission times are data transmission times of the target network slice in the current period.
If the average value of the plurality of data transmission times of the target network slice is less than or equal to the first preset value, the network device executes step 605; if the average value of the plurality of data transmission times of the target network slice is greater than the first preset value and the variance of the plurality of data transmission times is less than or equal to the second preset value, the network device executes step 606; if the average value of the plurality of data transmission times of the target network slice is greater than the first preset value and the variance of the plurality of data transmission times is greater than the second preset value, the network device executes step 607.
Step 605, the network device initializes a counter and continues with step 604.
Step 606, the network device subtracts the first accumulated value from the time slot intervals of all the terminals of the target network slice.
In step 607, the network device subtracts the first accumulated value from the time slot interval of the terminal whose channel quality is lower than the preset intensity in the target network slice.
The descriptions of the steps 602 to 607 may refer to the descriptions of fig. 3, which are not repeated herein.
It should be noted that, the network device may periodically perform the steps 604 to 607. That is, the network device completes steps 604 to 607 as one cycle. When the network device executes the steps 604 to 607 in each period, the acquired plurality of data transmission times are the data transmission times corresponding to the period.
Based on the technical solution of fig. 6, for a network slice in which subscription information includes a slot interval, the network device may adjust the slot interval configured by at least one terminal under the network slice according to a plurality of data transmission times of the network slice, so that a transmission delay between the adjusted terminal and the network device satisfies a preset data transmission time.
