Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Fig. 1 is a schematic flow chart of an SR configuration control method provided by the present invention. The SR configuration control method of the present invention is described below with reference to fig. 1. As shown in fig. 1, the method includes:
Step 101, the number of SRs detected in each time slot of the target cell is obtained.
It should be noted that, the execution body of the embodiment of the present invention is a base station.
Specifically, the medium access control layer (Medium Access Control, MAC) of the base station data link layer (L2) may acquire the number of SRs detected in each slot of the target cell by means of mathematical statistics, numerical calculation, or the like, and may record the number of SRs detected in each slot of the target cell as n_sr_avg. The target cell is a cell covered by the base station signal.
Note that n_sr_avg may be the number of SRs actually detected per slot of the target cell. The base station MAC layer may obtain the number of SRs actually detected per slot of the target cell based on a mathematical statistics method. n_sr_avg may also be the average number of SRs detected per slot of the target cell. The base station MAC layer may obtain the number of SRs actually detected by the current timeslot of the target cell and the number of SRs actually detected by each historical timeslot based on a mathematical statistics method, and may obtain, by a numerical calculation method, the average number of SRs detected by each timeslot of the target cell based on the number of SRs actually detected by the current timeslot of the target cell and the number of SRs actually detected by each historical timeslot, and may update the average number of SRs detected by each timeslot of the target cell based on the number of SRs actually detected by the next timeslot of the target cell.
Step 102, in the case that the number of SRs exceeds the first number threshold for a period of time exceeding the first time threshold, for each terminal in the camping target cell, first downlink control information is issued to the terminal, so that the terminal responds to the first downlink control information and sends the SRs based on the target SR configuration.
Specifically, the first number threshold may be determined according to actual conditions, and may be denoted as th_sr_num_up. The first time length threshold value can also be determined according to actual conditions and can be recorded as T 1 . In the embodiment of the invention, the TH_SR_NUM_UP and T are compared 1 The specific value of (2) is not limited.
If it is judged that the duration of n_sr_avg being larger than TH_SR_NUM_UP exceeds T 1 The base station MAC layer may report a first SR configuration indication to a radio resource control layer (Radio Resource Control, RRC) of the base station network layer (L3), and may mark the first SR configuration indication as sr_ind1.
After receiving the sr_ind1 reported by the base station MAC layer, the base station RRC layer may save all SR configuration information of the current base station, and may record all SR configuration information as sr_cfg0.
After receiving the sr_ind1 reported by the base station MAC layer, the base station RRC layer may further issue a first SR configuration message to the base station MAC layer, and may record the first SR configuration message as sr_cfg1.
After receiving the sr_cfg1 issued by the base station RRC layer, the base station MAC layer may issue first downlink control information (Downlink Control Information, DCI) to each terminal in the target cell, and may record the first downlink control information as dci_sr_cfg1.
Note that, the dci_sr_cfg1 may multiplex a Short message (Short Messages) format specified by DCI format 1_0 of the 38.212 protocol 7.3.1.2 section, and specific modes may include: DCI_SR_CFG1 can be scrambled by paging radio network temporary identifier (P-RNTI); the first two bits of the dci_sr_cfg1 content are short message indication (Short Messages Indicator) -2 bits and their value is equal to the reserved bit 00 in table 7.3.1.2.1-1 in 38.212 protocol; the third bit of the dci_sr_cfg1 content is 0; the subsequent content of DCI_SR_CFG1 is filled in according to the Short Messages format; DCI_SR_CFG1 is scheduled according to the Short Messages scheduling rule. Table 1 is a table 7.3.1.2.1-1 in the 38.212 protocol.
TABLE 1 38.212 protocol Table 7.3.1.2.1-1:Short Message indicator
In the embodiment of the invention, the DCI_SR_CFG1 adopts the mode of multiplexing the reserved bits of short messages in the 38.212 protocol, so that each terminal in the target cell can be prevented from being informed in an RRC signaling mode, and a large amount of extra signaling overhead can be avoided. The SR_CFG1 is issued to the base station MAC through the base station RRC layer, so that the short messages flow can be multiplexed, and the operation efficiency is improved.
For each terminal in the target cell, after the terminal receives dci_sr_cfg1 issued by the base station RRC layer, each SR configuration of the current terminal configuration may be saved in response to dci_sr_cfg1, and each SR configuration may be denoted as rrc_sr_cfg1.
The terminal may determine a target SR configuration for the terminal based on the rrc_sr_cfg1 of the terminal, according to a predetermined peer-to-peer convention between the terminal and the base station, and may record the target SR configuration as sr_cfg_h. At most, each terminal in the target cell is configured with only one SR configuration.
It should be noted that, according to a predetermined peer-to-peer agreement between the terminal and the base station, an SR with the highest priority level in the rrc_sr_cfg1 of the terminal may be configured as sr_cfg_h of the terminal; or, a SR in the rrc_sr_cfg1 of the terminal may be configured as sr_cfg_h of the terminal based on the actual requirement. In the embodiment of the present invention, the peer-to-peer engagement predetermined according to the terminal and the base station is not particularly limited.
After determining the sr_cfg_h of the terminal, the terminal may only reserve the sr_cfg_h. The SRs of all the logical channels of the terminal are not transmitted according to the original configuration rule any more, and the SRs are transmitted based on sr_cfg_h of the terminal.
It should be noted that, the original configuration rule may be a rule that the terminal transmits SR before the base station issues dci_sr_cfg1, that is, each terminal may transmit SR to the base station based on sr_cfg0. The original configuration rule may be determined according to actual situations, which is not specifically limited in the embodiment of the present invention.
It should be noted that, the terminal may also save each current SR configuration for standby.
It should be noted that, after the base station RRC layer issues dci_sr_cfg1, the ue of the new access base station will not receive dci_sr_cfg1, and the ue of the new access base station will retain the original SR configurations and send SRs according to the original configuration rules.
When the physical layer of the base station detects and schedules all the SRs in the target cell in each time slot, the detection is only the SR sent by each terminal in the target cell based on the sr_cfg_h of the terminal, so that the quantity of the SRs detected and scheduled in each time slot of the physical layer of the base station is greatly reduced, and the average time consumption of the detection and the scheduling of the SRs in each time slot of the physical layer of the base station is reduced.
According to the embodiment of the invention, after the base station determines that the time length of the detected SRs of each time slot of the target cell exceeds the first time length threshold value, the first downlink control information is issued to each terminal in the target cell, the terminal responds to the first downlink control information and sends the SRs based on the target SR configuration determined according to the current SR configurations of the terminal, and the base station only detects and schedules the SRs sent by the terminal based on the target SR configuration, so that the number of the SRs detected and scheduled by the base station can be reduced under the condition that the number of the terminals residing in the target cell is more or the number of the SRs detected by the base station in each time slot of the target cell is more, the average time consumption of the detection and scheduling of the SRs by the base station can be reduced, the detection and scheduling timeout of the base station to the SR configuration can be avoided, the control of the SR configuration is more flexible and more efficient, and the communication quality can be improved.
Based on the foregoing embodiments, in a case where the duration of the number of SRs greater than the first number threshold exceeds the first time length threshold, for each terminal camping on the target cell, first downlink control information is issued to the terminal, so that the terminal responds to the first downlink control information, and after transmitting the SR based on the target SR configuration, the method further includes: and under the condition that the number of the SRs is not more than the second number threshold and the duration exceeds the second duration threshold, transmitting second downlink control information to the terminal, so that the terminal responds to the second downlink control information and transmits the SRs based on the original configuration rule.
Specifically, the second number threshold may be determined according to actual conditions, and may be denoted as th_sr_num_down. The second time length threshold value can also be determined according to the actual situation and can be recorded as T 2 . In the embodiment of the invention, the method comprises the following steps of TH_SR_NUM_DOWN and T 2 The specific value of (2) is not limited.
It should be noted that, in the embodiment of the present invention, th_sr_num_down is smaller than th_sr_num_up.
After the physical layer of the base station detects and schedules only the SR sent by each terminal in the target cell based on sr_cfg_h of the terminal, if it is determined that n_sr_avg is less than or equal to TH/u The sr_num_down duration exceeds T 2 The base station MAC layer may report a second SR configuration indication to the base station RRC layer, and may mark the second SR configuration indication as sr_ind2.
After receiving the sr_ind2 reported by the base station MAC layer, the base station RRC layer may issue a second SR configuration message to the base station MAC layer, and may use sr_cfg0 as the second SR configuration message sr_cfg2, so that the base station RRC layer configuration information calculation process may be simplified.
After receiving the sr_cfg2, the base station MAC layer may issue second downlink control information to each terminal in the target cell, and may record the second downlink control information as dci_sr_cfg2.
Note that, the dci_sr_cfg2 may multiplex a Short message (Short Messages) format specified by DCI format 1_0 of the 38.212 protocol 7.3.1.2 section, and specific modes may include: DCI_SR_CFG2 can be scrambled by paging radio network temporary identifier (P-RNTI); the first two bits of the dci_sr_cfg2 content are short message indication (Short Messages Indicator) -2 bits and their value is equal to the reserved bit 00 in table 7.3.1.2.1-1 in 38.212 protocol; the third bit of the dci_sr_cfg2 content is 0; the subsequent content of DCI_SR_CFG1 is filled in according to the Short Messages format; DCI_SR_CFG2 is scheduled according to the Short Messages scheduling rule. Wherein, table 7.3.1.2.1-1 in the 38.212 protocol is shown in Table 1.
In the embodiment of the invention, the DCI_SR_CFG2 adopts the mode of multiplexing the reserved bits of short messages in the 38.212 protocol, so that each terminal in the target cell can be prevented from being informed in an RRC signaling mode, and a large amount of extra signaling overhead can be avoided. The SR_CFG2 is issued to the base station MAC through the base station RRC layer, so that the short messages flow can be multiplexed, and the operation efficiency is improved.
For each terminal in the target cell, after the terminal receives dci_sr_cfg2 issued by the base station RRC layer, in response to dci_sr_cfg2, sr_cfg_h of the terminal may be deleted, the stored rrc_sr_cfg1 of the terminal may be recovered, and SR may be sent according to the original configuration rule based on the stored rrc_sr_cfg1 of the terminal.
The physical layer of the base station can detect and schedule the SRs sent by each terminal in the target cell according to the original configuration rule based on the saved rrc_sr_cfg1 of the terminal, so as to meet more diversified service requirements under the condition that the number of terminals residing in the target cell is less or the number of SRs detected and scheduled by the physical layer of the base station per time slot is less.
According to the embodiment of the invention, after the base station determines that the time length of the SR detected by each time slot of the target cell is not more than the second number threshold exceeds the second time length threshold, the second downlink control information is issued to each terminal in the target cell, and the terminal responds to the second downlink control information and sends the SR based on the original configuration rule, so that more diversified service demands can be met under the condition that the number of terminals residing in the target cell is less or the number of the SR detected by the base station in each time slot of the target cell is less.
FIG. 2 is a second flowchart of an SR configuration control method provided by the present invention. The SR configuration control method of the present invention is described below with reference to fig. 2. As shown in fig. 2, the method includes: step 201, receiving first downlink control information sent by a base station. The first downlink control information is sent by the base station when the duration that the number of SRs detected by each time slot of the target cell is greater than the first number threshold exceeds the first time length threshold.
It should be noted that, the execution body in the embodiment of the present invention is each terminal in the target cell. The target cell is a cell covered by the base station signal.
Specifically, after the base station MAC layer acquires the number of SRs n_sr_avg detected in each time slot of the target cell, if it is determined that the duration of n_sr_avg is greater than th_sr_num_up exceeds T 1 The base station MAC layer may report a first SR configuration indication sr_ind1 to the base station RRC layer. The TH_SR_NUM_UP is used for determining a first quantity threshold according to actual conditions; t (T) 1 The first time length threshold value is determined according to actual conditions. In the embodiment of the invention, the TH_SR_NUM_UP and T are compared 1 The specific value of (2) is not limited.
After receiving the sr_ind1 reported by the base station MAC layer, the base station RRC layer may save all SR configuration information of the current base station, and may record all SR configuration information as sr_cfg0.
After receiving the sr_ind1 reported by the base station MAC layer, the base station RRC layer may further issue a first SR configuration message sr_cfg1 to the base station MAC layer.

It should be noted that, according to a predetermined peer-to-peer agreement between the terminal and the base station, an SR with the highest priority level in the rrc_sr_cfg1 of the terminal may be configured as sr_cfg_h of the terminal; or, a SR in the rrc_sr_cfg1 of the terminal may be configured as sr_cfg_h of the terminal based on the actual requirement. In the embodiment of the present invention, the peer-to-peer engagement predetermined according to the terminal and the base station is not particularly limited.

When the physical layer of the base station detects and schedules all the SRs in the target cell in each time slot, the detection is only the SR sent by each terminal in the target cell based on the sr_cfg_h of the terminal, so that the quantity of the SRs detected and scheduled in each time slot of the physical layer of the base station is greatly reduced, and the average time consumption of the detection and the scheduling of the SRs in each time slot of the physical layer of the base station is reduced.
It should be noted that, after the base station RRC layer issues dci_sr_cfg1, the ue of the new access base station will not receive dci_sr_cfg1, and the ue of the new access base station will retain the original SR configurations and send SRs based on the original configuration rules.
According to the embodiment of the invention, after the base station determines that the time length of the SR detected by each time slot of the target cell exceeds the first time length threshold value, the first downlink control information is issued to each terminal in the target cell, the terminal responds to the first downlink control information and sends the SR based on the target SR configuration determined according to the current SR configurations of the terminal, and the base station only detects and schedules the SR sent by the terminal based on the target SR configuration, so that the number of the SR detected and scheduled by each time slot of the base station can be reduced under the condition that the number of the terminals residing in the target cell is more or the number of the SR detected by each time slot of the base station is more, the average time consumption of the SR detected and scheduled by each time slot of the base station can be reduced, the detection and scheduling timeout of the SR by the base station can be avoided, the control over the SR configuration is more flexible and more efficient, and the communication quality can be improved.
Based on the content of the above embodiments, the above method further includes: receiving second downlink control information sent by a base station; the second downlink control information is sent by the base station when the duration of the SR number not greater than the second number threshold exceeds the second duration threshold.
Specifically, after the physical layer of the base station detects and schedules only SR sent by each terminal in the target cell based on sr_cfg_h of the terminal, if it is determined that n_sr_avg is less than or equal to th_sr_num_down for a period of time exceeding T 2 The base station MAC layer may report a second SR configuration indication sr_ind2 to the base station RRC layer. The TH_SR_NUM_DOWN is used for determining a second quantity threshold according to actual conditions; t (T) 2 And determining a second time duration threshold according to the actual situation. In the embodiment of the invention, the method comprises the following steps of TH_SR_NUM_DOWN and T 2 The specific value of (2) is not limited.
