In a first aspect, an embodiment of the present application provides a terminal scheduling method, including: determining whether interference exists between a service beam and other beams according to the downlink interference isolation and/or the uplink interference isolation between the service beam and the other beams; if interference exists between the service beam and the other beams, scheduling the service beam and the other beams; wherein the scheduling comprises frequency division scheduling and/or HARQ resource scheduling.
In the scheme, whether interference exists between the service beam and other beams can be determined according to the isolation degree between the service beam and other beams, and under the condition that interference exists between the service beam and other beams, the service beam and other beams can be correspondingly scheduled, so that interference can not exist between the service beam and other beams in the process of data transmission.
In an optional embodiment, the determining whether there is interference between the service beam and the other beam according to the downlink interference isolation and/or the uplink interference isolation between the service beam and the other beam includes: if the service beam is used for downlink data transmission and non-HARQ scheduling is adopted, judging whether the downlink interference isolation between the service beam and the other beams is smaller than a first threshold value; and the downlink interference isolation between the service beam and the other beams is not smaller than the first threshold value, so that the service beam and the other beams are characterized in that no interference exists. In the above scheme, when the service beam is used for downlink data transmission and non-HARQ scheduling is adopted, whether interference exists between the service beam and other beams can be determined by judging whether the downlink interference isolation is smaller than the first threshold, so that corresponding scheduling can be performed when interference exists, and the service beam and other beams are ensured not to have interference in the process of data transmission.
In an optional embodiment, channels corresponding to the service beam and the other beams include PDCCH and PDSCH, and the scheduling the service beam and the other beams includes: if the isolation degree of downlink interference between the service beam and the other beams is smaller than the first threshold, judging whether the PDCCH and the PDSCH can perform frequency division scheduling or not; and if the PDCCH and the PDSCH can perform frequency division scheduling, selecting the PDCCH and the PDSCH which do not collide in the frequency domain to perform frequency division scheduling on the service beam and the other beams.

Wherein, the dispatching terminal is not directly stopped when the interference is perceived, so the uplink and downlink throughput of the user is not affected.

Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.
Referring to fig. 1, fig. 1 is a flowchart of a terminal scheduling method according to an embodiment of the present application, where the terminal scheduling method specifically includes the following steps:
Step S101: and determining whether interference exists between the service beam and other beams according to the downlink interference isolation and/or the uplink interference isolation between the service beam and other beams.
Step S102: if interference exists between the service beam and other beams, scheduling the service beam and other beams; wherein the scheduling includes frequency division scheduling and/or HARQ resource scheduling.
Specifically, in the above step S101, the Service Beam (Service Beam) is formed by applying specific amplitude and phase excitation to the smart antenna array, and has any Beam pointing scanning capability and a high-gain narrow Beam pattern within the operating angle. The service beam is mainly used for tracking users or equipment, ensuring continuity and quality of data transmission, and allowing multiple users to be connected simultaneously, so that the overall capacity and efficiency of the system are improved.
In the embodiment of the present application, the service beam may refer to a current beam, and the other beams refer to beams other than the current beam. It should be noted that, as an embodiment, other beams may belong to a service beam; as another implementation, other beams may not belong to the traffic beam.
When the traffic beam and the other beams belong to the same frequency beam, interference may exist between the traffic beam and the other beams. For example, referring to fig. 2, fig. 2 is a schematic diagram of a wave position planning provided by an embodiment of the present application, where a wave position refers to a coverage area of a Beam on the ground, and Beam #0 and Beam #1 in fig. 2 are adjacent wave positions; when Beam 1 is directed to Beam #0 and Beam 2 is simultaneously directed to Beam #1, the two beams interfere with each other.
To avoid interference between the traffic beam and the other beams, it may be determined whether interference between the traffic beam and the other beams exists based on interference isolation between the traffic beam and the other beams. Isolation INTERFERENCE DEGREE is used to measure the performance degradation caused by mutual interference between different beams. In one embodiment, the interference isolation may be represented by the distance between the center points of the beam pointing to the ground; as another embodiment, the interference isolation may also be expressed in terms of the angle between the two beams.
In the embodiment of the present application, the Isolation interference may include a downlink interference Isolation (Downlink Isolation INTERFERENCE DEGREE) and an Uplink interference Isolation (Uplink Isolation INTERFERENCE DEGREE); the downlink interference isolation is used for measuring the interference degree between different beams in the downlink data transmission process, and the uplink interference isolation is used for measuring the interference degree between different beams in the uplink data transmission process.
As a first embodiment, whether interference exists between the service beam and other beams may be determined according to the downlink interference isolation between the service beam and other beams; as a second embodiment, whether interference exists between the service beam and other beams may be determined according to uplink interference isolation between the service beam and other beams; as a third embodiment, whether or not there is interference between the service beam and the other beam may be determined according to the downlink interference isolation and the uplink interference isolation between the service beam and the other beam.
It should be noted that, the specific implementation manner of determining the downlink interference isolation and the uplink interference isolation in the embodiment of the present application is not specifically limited, and those skilled in the art may perform appropriate adjustment according to actual situations. For example, by monitoring and analyzing the downlink signal using a professional wireless test device; or calculated from the data related to the downlink signal, etc.
In addition, the embodiment of the present application is not limited in particular to the specific implementation manner of determining whether interference exists between the service beam and other beams, and those skilled in the art may make appropriate adjustments according to practical situations. For example, it may be determined whether there is interference between the traffic beam and other beams by comparing the magnitude relationship between the isolation interference and the interference threshold; or a neural network model can be trained according to the related data of the data transmission, and whether interference exists between the service beam and other beams or not can be determined by utilizing the model.
It can be appreciated that if there is no interference between the service beam and other beams, the service terminal may still be scanned and scheduled towards the target terminal; if there is interference between the traffic beam and other beams, step S102 may be performed, i.e. the traffic beam and other beams may be scheduled. After the scheduling, the interference between the service beam and other beams can be avoided, thereby ensuring the normal operation of uplink and downlink scheduling.
In the above step S102, as a first embodiment, the scheduling of the service beam and the other beams may include frequency division scheduling of the service beam and the other beams; as a second embodiment, scheduling the traffic beam and other beams may include scheduling the traffic beam and other beams for hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) resource scheduling; as a third embodiment, scheduling the traffic beam and other beams may include frequency division scheduling the traffic beam and other beams as well as HARQ resource scheduling.
The method comprises the steps of carrying out frequency division scheduling on service beams and other beams, namely carrying out target terminal scanning and scheduling on channels which are not in conflict with the frequency domain selected by the service beams and the other beams; and scheduling the service beam and other beams to perform HARQ resource scheduling, namely, performing target terminal scanning and scheduling on the service beam and other beam selection and the HARQ feedback resources which are not scheduled in the same time slot.
It may be appreciated that in the above scheduling process, if there is a frequency domain collision or HARQ feedback resource collision, the target terminal may not be scheduled.
It should be noted that, the specific implementation manner of the scheduling of the service beam and other beams according to the embodiments of the present application is not limited in particular, and those skilled in the art may make appropriate adjustments according to practical situations. For example, when HARQ scheduling is employed, the traffic beam and other beams may be scheduled for HARQ resource scheduling; when the channels can be frequency division multiplexed, the traffic beam and other beams can be frequency division scheduled, etc.
In the scheme, whether interference exists between the service beam and other beams can be determined according to the isolation degree between the service beam and other beams, and under the condition that interference exists between the service beam and other beams, the service beam and other beams can be correspondingly scheduled, so that interference can not exist between the service beam and other beams in the process of data transmission.
Further, on the basis of the above embodiment, the service beam may be applied to uplink data transmission or downlink data transmission; in case the traffic beam is applied for downlink data transmission, the traffic beam may employ non-HARQ scheduling or HARQ scheduling.
Therefore, in the embodiment of the present application, the following three cases can be classified: in the first case, the service beam is used for downlink data transmission and non-HARQ scheduling is adopted; in the second case, the service beam is used for downlink data transmission and adopts HARQ scheduling; in the third case, the traffic beam is used for uplink data transmission. The following describes in detail the specific embodiments of step S101 and step S102 in order in the above three cases.
For the first case, the step S101 may specifically include the following steps:
If the service beam is used for downlink data transmission and non-HARQ scheduling is adopted, judging whether the isolation degree of downlink interference between the service beam and other beams is smaller than a first threshold value.
Specifically, as an embodiment, the first threshold in the above step may be a fixed value set in advance; as another embodiment, the first threshold in the above step may be a variable, and the magnitude of the first threshold may be changed according to the actual situation.
When the isolation degree of downlink interference between the service beam and other beams is not smaller than a first threshold, it can be considered that no interference exists between the service beam and other beams or that the interference exists between the service beam and other beams is smaller; when the isolation of the downlink interference between the service beam and the other beams is smaller than the first threshold, it can be considered that there is a larger interference between the service beam and the other beams.
Therefore, when the isolation degree of downlink interference between the service beam and other beams is not less than the first threshold, the service beam can still point to the target terminal to scan and schedule; when the downlink interference isolation between the traffic beam and the other beams is less than a first threshold, the traffic beam and the other beams may be scheduled.
In the above scheme, when the service beam is used for downlink data transmission and non-HARQ scheduling is adopted, whether interference exists between the service beam and other beams can be determined by judging whether the downlink interference isolation is smaller than the first threshold, so that corresponding scheduling can be performed when interference exists, and the service beam and other beams are ensured not to have interference in the process of data transmission.
Further, based on the above embodiment, when the downlink interference isolation between the service beam and other beams is smaller than the first threshold, if the channels corresponding to the service beam and other beams include PDCCH and PDSCH, the step S102 may specifically include the following steps:
And step 1), if the isolation degree of downlink interference between the service beam and other beams is smaller than a first threshold value, judging whether the PDCCH and the PDSCH can perform frequency division scheduling.
Step 2), if the PDCCH and the PDSCH can perform frequency division scheduling, selecting the PDCCH and the PDSCH which do not collide in the frequency domain to perform frequency division scheduling on the service beam and other beams.
Specifically, in step 1), when the isolation between the downlink interference between the service beam and other beams is smaller than the first threshold, it may be further determined whether the corresponding channel can perform frequency division scheduling. When the channel cannot be subjected to frequency division scheduling, the target terminal cannot be scheduled; when the channel can be frequency division scheduled, the service beam and other beams can be frequency division scheduled.
In the embodiment of the present application, channels corresponding to the traffic beam and other beams may include a physical downlink control channel (Physical Downlink Control Channel, PDCCH) and a physical downlink shared channel (Physical Downlink SHARED CHANNEL, PDSCH); in this case, it may be determined whether or not the PDCCH and the PDSCH can be frequency-division scheduled.
Frequency division multiplexing (Frequency Division Multiplexing, FDM) is an important multiple access technique for sharing frequency resources among multiple users or services; in a frequency division multiplexed system, different users or services may be allocated for data transmission on different frequency resources.
The PDCCH is a physical channel for transmitting downlink control information, and the frequency division scheduling of the PDCCH refers to the process of distributing and scheduling data on the PDCCH on frequency resources; PDSCH is a physical channel for transmitting user data, and frequency division scheduling of PDSCH refers to a process of allocating and scheduling data on PDSCH on frequency resources.
In the step 2), if the PDCCH and the PDSCH can perform frequency division scheduling, the service beam and other beams can be scheduled; specifically, a PDCCH and PDSCH that do not collide in the frequency domain may be selected for frequency division scheduling of traffic beams and other beams.
For PDCCH, for example, please refer to fig. 3, fig. 3 is a schematic diagram of PDCCH detection space configured by different terminals according to an embodiment of the present application, wherein ms (monitoring space) represents a detection space of a Control channel unit (Control CHANNEL ELEMENT, CCE) of the terminal at the aggregation level, and a coloring area is a search space for detecting PDCCH corresponding to the aggregation level of each terminal.
As an embodiment, different CCEs may be used for the purpose of frequency division, for example: when the aggregation level l=8, the PDCCH may be sent to UE1 on CCEs 0-7 and to UE2 on CCEs 16-23; as another embodiment, different aggregation levels may be used for frequency division purposes, for example: the UE1 aggregation level l=8 may send PDCCH to UE1 on CCEs 0-7, and the UE2 aggregation level l=16 may send PDCCH on CCEs 16-31.
For PDSCH, physical resource blocks (Physical Resource Block, PRBs) may be aggregated into resource block groups (Resource Block Group, RBGs), with the RBGs used for this scheduling indicated by means of bitmap.
As an embodiment, the frequency division of the continuous RBG may be used for the purpose of frequency division, for example: referring to fig. 4, fig. 4 is a schematic diagram of a PDSCH/PUSCH frequency division manner provided by an embodiment of the present application, where a coloring area in fig. 4 indicates RBGs corresponding to the UE, that is, UE1 uses RBGs 0 to 7 and UE2 uses RBGs 8 to 16; as another embodiment, the purpose of frequency division can be achieved by shifting RBGs with respect to each other, for example: referring to fig. 5, fig. 5 is a schematic diagram of another PDSCH/PUSCH frequency division method provided by the embodiment of the present application, and the colored region in fig. 5 also indicates an RBG corresponding to the UE, that is, the RBG is used by UE 1: 1/3/5/7/9/11/13/15, ue2 uses RBG:0/2/4/6/8/10/12/14/16.
In the above scheme, the downlink interference isolation is smaller than the first threshold to indicate that interference exists between the service beam and other beams, so that the service beam and other beams can be subjected to frequency division scheduling by selecting the PDCCH and the PDSCH which do not collide in the frequency domain, and the interference between the service beam and other beams is avoided. Wherein, the dispatching terminal is not directly stopped when the interference is perceived, so the uplink and downlink throughput of the user is not affected.
For the second case, the step S101 may specifically include the following steps:
If the service beam is used for downlink data transmission and HARQ scheduling is adopted, judging whether the downlink interference isolation between the service beam and other beams is smaller than a first threshold value or not, and judging whether the uplink interference isolation between the service beam and other beams is smaller than a second threshold value or not.
Specifically, if the service beam is used for downlink data transmission and HARQ scheduling is adopted, since uplink feedback is required for HARQ scheduling, the uplink interference isolation between the service beam and other beams needs to be considered in addition to the downlink interference isolation between the service beam and other beams.
As an embodiment, the first threshold in the above step may be a fixed value set in advance; as another embodiment, the first threshold may be a variable whose value varies according to the actual situation.
Similarly, for the second threshold in the above step, as an embodiment, the second threshold may be a fixed value set in advance; as another embodiment, the second threshold may be a variable whose value varies according to the actual situation.
The half-power bandwidths of the uplink and downlink beams are not necessarily the same due to frequency points and the like, so that the uplink and downlink interference isolation thresholds may be different. That is, the magnitude relation between the first threshold and the second threshold is not specifically limited in the embodiments of the present application, and those skilled in the art may perform appropriate adjustment according to actual situations, for example: the first threshold is greater than the second threshold, the first threshold is less than the second threshold, or the first threshold is equal to the second threshold.
When the downlink interference isolation between the service beam and other beams is not less than a first threshold value and the uplink interference isolation between the service beam and other beams is not less than a second threshold value, it can be considered that no interference exists between the service beam and other beams or that the interference exists between the service beam and other beams is small; thus, the traffic beam may still be directed to the target terminal for scanning and scheduling.
When the downlink interference isolation between the service beam and other beams is not less than the first threshold and the uplink interference isolation between the service beam and other beams is less than the second threshold, the uplink data transmission between the service beam and other beams can be considered to have larger interference; thus, traffic beams and other beams may be scheduled.
When the downlink interference isolation between the service beam and other beams is smaller than a first threshold value and the uplink interference isolation between the service beam and other beams is not smaller than a second threshold value, the downlink data transmission between the service beam and other beams can be considered to have larger interference; thus, traffic beams and other beams may be scheduled.
When the downlink interference isolation between the service beam and other beams is smaller than a first threshold value and the uplink interference isolation between the service beam and other beams is smaller than a second threshold value, the uplink data transmission and the downlink data transmission between the service beam and other beams can be considered to have larger interference; thus, traffic beams and other beams may be scheduled.
In the above scheme, when the service beam is used for downlink data transmission and the HARQ scheduling is adopted, since the HARQ scheduling requires uplink feedback, whether interference exists between the service beam and other beams can be determined by simultaneously judging whether the downlink interference isolation is smaller than the first threshold and whether the uplink interference isolation is smaller than the second threshold, so that corresponding scheduling can be performed when interference exists, and interference between the service beam and other beams in the data transmission process can be avoided.
Further, on the basis of the above embodiment, when the downlink interference isolation between the service beam and the other beams is not less than the first threshold and the uplink interference isolation between the service beam and the other beams is less than the second threshold, if the channels corresponding to the service beam and the other beams include PDCCH and PDSCH, the step S102 may specifically include the following steps:
And if the downlink interference isolation between the service beam and other beams is not smaller than the first threshold value and the uplink interference isolation between the service beam and other beams is smaller than the second threshold value, selecting the HARQ feedback resources which are not scheduled in the same time slot to perform HARQ resource scheduling on the service beam and other beams.
Specifically, when the downlink interference isolation between the service beam and other beams is not less than a first threshold and the uplink interference isolation between the service beam and other beams is less than a second threshold, the service beam and other beams can be subjected to HARQ resource scheduling; specifically, HARQ feedback resources not scheduled in the same time slot may be selected to schedule HARQ resources for the traffic beam and other beams. Note that if there is a conflict in the HARQ feedback resource, the target terminal may not be scheduled.
In the above scheme, the downlink interference isolation is not less than the first threshold value and the uplink interference isolation is less than the second threshold value, so that the interference between the service beam and other beams is represented, and therefore, the service beam and other beams can be subjected to HARQ resource scheduling by selecting the HARQ feedback resources which are not scheduled in the same time slot, so that the interference between the service beam and other beams is avoided. Wherein, the dispatching terminal is not directly stopped when the interference is perceived, so the uplink and downlink throughput of the user is not affected.
Further, based on the above embodiment, when the downlink interference isolation between the service beam and the other beams is smaller than the first threshold and the uplink interference isolation between the service beam and the other beams is not smaller than the second threshold, if the channels corresponding to the service beam and the other beams include PDCCH and PDSCH, the step S102 may specifically include the following steps:
step 1), if the downlink interference isolation between the service beam and other beams is smaller than a first threshold value and the uplink interference isolation between the service beam and other beams is not smaller than a second threshold value, judging whether the PDCCH and the PDSCH can perform frequency division scheduling.
Step 2), if the PDCCH and the PDSCH can perform frequency division scheduling, selecting the PDCCH and the PDSCH which do not collide in the frequency domain to perform frequency division scheduling on the service beam and other beams.
Specifically, in step 1), when the downlink interference isolation between the service beam and the other beams is smaller than the first threshold, and the uplink interference isolation between the service beam and the other beams is not smaller than the second threshold, it may be further determined whether the corresponding channels can perform frequency division scheduling. When the channel cannot be subjected to frequency division scheduling, the target terminal cannot be scheduled; when the channel can be frequency division scheduled, the service beam and other beams can be frequency division scheduled.
In the embodiment of the application, channels corresponding to the service beam and other beams can comprise PDCCH and PDSCH; in this case, it may be determined whether or not the PDCCH and the PDSCH can be frequency-division scheduled.
In the step 2), if the PDCCH and the PDSCH can perform frequency division scheduling, the service beam and other beams can be scheduled; specifically, a PDCCH and PDSCH that do not collide in the frequency domain may be selected for frequency division scheduling of traffic beams and other beams.
For PDCCH, for example, please refer to fig. 3, fig. 3 is a schematic diagram of PDCCH detection space configured by different terminals according to an embodiment of the present application, wherein ms (monitoring space) represents a detection space of a Control channel unit (Control CHANNEL ELEMENT, CCE) of the terminal at the aggregation level, and a coloring area is a search space for detecting PDCCH corresponding to the aggregation level of each terminal.
As an embodiment, different CCEs may be used for the purpose of frequency division, for example: when the aggregation level l=8, the PDCCH may be sent to UE1 on CCEs 0-7 and to UE2 on CCEs 16-23; as another embodiment, different aggregation levels may be used for frequency division purposes, for example: the UE1 aggregation level l=8 may send PDCCH to UE1 on CCEs 0-7, and the UE2 aggregation level l=16 may send PDCCH on CCEs 16-31.
For PDSCH, PRBs may be aggregated into RBGs, and the RBGs used for this scheduling may be indicated by means of bitmap. As an embodiment, the frequency division of the continuous RBG may be used for the purpose of frequency division, for example: referring to fig. 4, fig. 4 is a schematic diagram of a PDSCH/PUSCH frequency division manner provided by an embodiment of the present application, where a coloring area in fig. 4 indicates RBGs corresponding to the UE, that is, UE1 uses RBGs 0 to 7 and UE2 uses RBGs 8 to 16; as another embodiment, the purpose of frequency division can be achieved by shifting RBGs with respect to each other, for example: referring to fig. 5, fig. 5 is a schematic diagram of another PDSCH/PUSCH frequency division method provided by the embodiment of the present application, and the colored region in fig. 5 also indicates an RBG corresponding to the UE, that is, the RBG is used by UE 1: 1/3/5/7/9/11/13/15, ue2 uses RBG:0/2/4/6/8/10/12/14/16.
In the above scheme, the downlink interference isolation is smaller than the first threshold value, and the uplink interference isolation is not smaller than the second threshold value, so that the interference between the service beam and other beams is represented, and therefore the service beam and other beams can be subjected to frequency division scheduling by selecting the PDCCH and the PDSCH which do not collide in the frequency domain, and the interference between the service beam and other beams is avoided. Wherein, the dispatching terminal is not directly stopped when the interference is perceived, so the uplink and downlink throughput of the user is not affected.
Further, based on the above embodiment, when the downlink interference isolation between the service beam and the other beams is smaller than the first threshold and the uplink interference isolation between the service beam and the other beams is smaller than the second threshold, if the channels corresponding to the service beam and the other beams include PDCCH and PDSCH, the step S102 may specifically include the following steps:
step 1), if the downlink interference isolation between the service beam and other beams is smaller than a first threshold value and the uplink interference isolation between the service beam and other beams is smaller than a second threshold value, judging whether the PDCCH and the PDSCH can perform frequency division scheduling.
Step 2), if the PDCCH and the PDSCH can perform frequency division scheduling, selecting the PDCCH and the PDSCH which do not collide in the frequency domain to perform frequency division scheduling on the service beam and other beams, and selecting the HARQ feedback resource which is not scheduled in the same time slot to perform HARQ resource scheduling on the service beam and other beams.
Specifically, in step 1), when the downlink interference isolation between the service beam and the other beams is smaller than the first threshold, and the uplink interference isolation between the service beam and the other beams is smaller than the second threshold, it may be further determined whether the corresponding channels can perform frequency division scheduling. When the channel cannot be subjected to frequency division scheduling, the target terminal cannot be scheduled; when the channel can perform frequency division scheduling, the service beam and other beams can be subjected to frequency division scheduling and HARQ resource scheduling.
In the embodiment of the application, channels corresponding to the service beam and other beams can comprise PDCCH and PDSCH; in this case, it may be determined whether or not the PDCCH and the PDSCH can be frequency-division scheduled.
In the step 2), if the PDCCH and the PDSCH can perform frequency division scheduling, the service beam and other beams may be frequency division scheduled, specifically, the PDCCH and the PDSCH that do not collide in the frequency domain may be selected to perform frequency division scheduling on the service beam and other beams; and, the service beam and other beams may be subjected to HARQ resource scheduling, and in particular, the service beam and other beams may be subjected to HARQ resource scheduling by selecting the HARQ feedback resources which are not scheduled in the same time slot. Note that if there is a conflict in the HARQ feedback resource, the target terminal may not be scheduled.
For PDCCH, for example, please refer to fig. 3, fig. 3 is a schematic diagram of PDCCH detection space configured by different terminals according to an embodiment of the present application, wherein ms (monitoring space) represents a detection space of a Control channel unit (Control CHANNEL ELEMENT, CCE) of the terminal at the aggregation level, and a coloring area is a search space for detecting PDCCH corresponding to the aggregation level of each terminal.
As an embodiment, different CCEs may be used for the purpose of frequency division, for example: when the aggregation level l=8, the PDCCH may be sent to UE1 on CCEs 0-7 and to UE2 on CCEs 16-23; as another embodiment, different aggregation levels may be used for frequency division purposes, for example: the UE1 aggregation level l=8 may send PDCCH to UE1 on CCEs 0-7, and the UE2 aggregation level l=16 may send PDCCH on CCEs 16-31.
For PDSCH, PRBs may be aggregated into RBGs, and the RBGs used for this scheduling may be indicated by means of bitmap. As an embodiment, the frequency division of the continuous RBG may be used for the purpose of frequency division, for example: referring to fig. 4, fig. 4 is a schematic diagram of a PDSCH/PUSCH frequency division manner provided by an embodiment of the present application, where a coloring area in fig. 4 indicates RBGs corresponding to the UE, that is, UE1 uses RBGs 0 to 7 and UE2 uses RBGs 8 to 16; as another embodiment, the purpose of frequency division can be achieved by shifting RBGs with respect to each other, for example: referring to fig. 5, fig. 5 is a schematic diagram of another PDSCH/PUSCH frequency division method provided by the embodiment of the present application, and the colored region in fig. 5 also indicates an RBG corresponding to the UE, that is, the RBG is used by UE 1: 1/3/5/7/9/11/13/15, ue2 uses RBG:0/2/4/6/8/10/12/14/16.
In the above scheme, the downlink interference isolation is smaller than the first threshold value and the uplink interference isolation is smaller than the second threshold value, so that interference between the service beam and other beams can be represented, and therefore, the service beam and other beams can be subjected to frequency division scheduling by selecting the PDCCH and the PDSCH which do not collide in the frequency domain, and HARQ (hybrid automatic repeat request) resource scheduling can be performed on the service beam and other beams by selecting the HARQ feedback resources which are not scheduled in the same time slot, so that interference between the service beam and other beams is avoided. Wherein, the dispatching terminal is not directly stopped when the interference is perceived, so the uplink and downlink throughput of the user is not affected.
For the third case, the step S101 may specifically include the following steps:
If the service beam is used for uplink data transmission, judging whether the downlink interference isolation between the service beam and other beams is smaller than a first threshold value, and judging whether the uplink interference isolation between the service beam and other beams is smaller than a second threshold value.
Specifically, for the first threshold in the above step, as an embodiment, the first threshold may be a fixed value that is set in advance; as another embodiment, the first threshold may be a variable whose value varies according to the actual situation.
Similarly, for the second threshold in the above step, as an embodiment, the second threshold may be a fixed value set in advance; as another embodiment, the second threshold may be a variable whose value varies according to the actual situation.
The half-power bandwidths of the uplink and downlink beams are not necessarily the same due to frequency points and the like, so that the uplink and downlink interference isolation thresholds may be different. That is, the magnitude relation between the first threshold and the second threshold is not specifically limited in the embodiments of the present application, and those skilled in the art may perform appropriate adjustment according to actual situations, for example: the first threshold is greater than the second threshold, the first threshold is less than the second threshold, or the first threshold is equal to the second threshold.
When the downlink interference isolation between the service beam and other beams is not less than a first threshold value and the uplink interference isolation between the service beam and other beams is not less than a second threshold value, it can be considered that no interference exists between the service beam and other beams or that the interference exists between the service beam and other beams is small; thus, the traffic beam may still be directed to the target terminal for scanning and scheduling.
When the downlink interference isolation between the service beam and other beams is not less than the first threshold and the uplink interference isolation between the service beam and other beams is less than the second threshold, the uplink data transmission between the service beam and other beams can be considered to have larger interference; thus, traffic beams and other beams may be scheduled.
When the downlink interference isolation between the service beam and other beams is smaller than a first threshold value and the uplink interference isolation between the service beam and other beams is not smaller than a second threshold value, the downlink data transmission between the service beam and other beams can be considered to have larger interference; thus, traffic beams and other beams may be scheduled.
When the downlink interference isolation between the service beam and other beams is smaller than a first threshold value and the uplink interference isolation between the service beam and other beams is smaller than a second threshold value, the uplink data transmission and the downlink data transmission between the service beam and other beams can be considered to have larger interference; thus, traffic beams and other beams may be scheduled.
It should be noted that, in the case where the traffic beam is used for uplink data transmission, whether there is interference between the traffic beam and other beams may be determined only by determining whether the uplink interference isolation between the traffic beam and other beams is smaller than the second threshold.
In the above scheme, when the service beam is used for uplink data transmission, whether interference exists between the service beam and other beams can be determined by judging whether the uplink interference isolation is smaller than the second threshold, so that corresponding scheduling can be performed when the interference exists, and the service beam and other beams are ensured not to have interference in the process of data transmission.
Further, on the basis of the foregoing embodiment, when the downlink interference isolation between the service beam and the other beams is not less than the first threshold and the uplink interference isolation between the service beam and the other beams is less than the second threshold, if the channels corresponding to the service beam and the other beams include PDCCH and PUSCH, the step S102 may specifically include the following steps:
step 1), if the downlink interference isolation between the service beam and other beams is not less than a first threshold and the uplink interference isolation between the service beam and other beams is less than a second threshold, judging whether the PUSCH can perform frequency division scheduling.
Step 2), if the PUSCH can perform frequency division scheduling, selecting the PUSCH with non-collision in the frequency domain to perform frequency division scheduling on the service beam and other beams.
Specifically, in step 1), when the downlink interference isolation between the service beam and the other beams is not less than the first threshold, and the uplink interference isolation between the service beam and the other beams is less than the second threshold, it may be further determined whether the corresponding channels can perform frequency division scheduling. When the channel cannot be subjected to frequency division scheduling, the target terminal cannot be scheduled; when the channel can be frequency division scheduled, the service beam and other beams can be frequency division scheduled.
In the embodiment of the present application, channels corresponding to the service beam and other beams may include a Physical Uplink shared channel (Physical Uplink SHARED CHANNEL, PUSCH); at this time, it can be determined whether or not the PUSCH can be frequency division scheduled. Wherein, PUSCH is a physical channel used for transmitting user data, and frequency division scheduling of PUSCH refers to a process of allocating and scheduling data on PDSCH on frequency resources.
In the step 2), if the PUSCH can perform frequency division scheduling, the service beam and other beams may be scheduled; specifically, PUSCH that does not collide in the frequency domain may be selected for frequency division scheduling of traffic beams and other beams.
For PUSCH, for PDSCH, PRBs may be aggregated into RBGs, and the RBGs used for this scheduling may be indicated by means of bitmap. As an embodiment, the frequency division of the continuous RBG may be used for the purpose of frequency division, for example: referring to fig. 4, fig. 4 is a schematic diagram of a PDSCH/PUSCH frequency division manner provided by an embodiment of the present application, where a coloring area in fig. 4 indicates RBGs corresponding to the UE, that is, UE1 uses RBGs 0 to 7 and UE2 uses RBGs 8 to 16; as another embodiment, the purpose of frequency division can be achieved by shifting RBGs with respect to each other, for example: referring to fig. 5, fig. 5 is a schematic diagram of another PDSCH/PUSCH frequency division method provided by the embodiment of the present application, and the colored region in fig. 5 also indicates an RBG corresponding to the UE, that is, the RBG is used by UE 1: 1/3/5/7/9/11/13/15, ue2 uses RBG:0/2/4/6/8/10/12/14/16.
In the above scheme, the downlink interference isolation is not less than the first threshold value and the uplink interference isolation is less than the second threshold value, so that the interference between the service beam and other beams is represented, and therefore the service beam and other beams can be subjected to frequency division scheduling by selecting the PUSCH with non-collision frequency domain, and the interference between the service beam and other beams is avoided. Wherein, the dispatching terminal is not directly stopped when the interference is perceived, so the uplink and downlink throughput of the user is not affected.
Further, on the basis of the above embodiment, when the downlink interference isolation between the service beam and the other beams is smaller than the first threshold and the uplink interference isolation between the service beam and the other beams is not smaller than the second threshold, if the channels corresponding to the service beam and the other beams include PDCCH and PUSCH, the step S102 may specifically include the following steps:
Step 1), if the downlink interference isolation between the service beam and other beams is smaller than a first threshold value and the uplink interference isolation between the service beam and other beams is not smaller than a second threshold value, judging whether the PDCCH can perform frequency division scheduling.
And 2) if the PDCCH can perform frequency division scheduling, selecting the PDCCH with non-collision in the frequency domain to perform frequency division scheduling on the service beam and other beams.
Specifically, in step 1), when the downlink interference isolation between the service beam and the other beams is smaller than the first threshold, and the uplink interference isolation between the service beam and the other beams is not smaller than the second threshold, it may be further determined whether the corresponding channels can perform frequency division scheduling. When the channel cannot be subjected to frequency division scheduling, the target terminal cannot be scheduled; when the channel can be frequency division scheduled, the service beam and other beams can be frequency division scheduled.
In the embodiment of the application, channels corresponding to the service beam and other beams can comprise PDCCH; at this time, it may be determined whether the PDCCH may be frequency-division scheduled.
In the step 2), if the PDCCH can perform frequency division scheduling, scheduling can be performed on the service beam and other beams; specifically, a PDCCH that does not collide in the frequency domain may be selected for frequency division scheduling of the traffic beam as well as other beams.
For PDCCH, for example, please refer to fig. 3, fig. 3 is a schematic diagram of PDCCH detection space configured by different terminals according to an embodiment of the present application, wherein ms (monitoring space) represents a detection space of a Control channel unit (Control CHANNEL ELEMENT, CCE) of the terminal at the aggregation level, and a coloring area is a search space for detecting PDCCH corresponding to the aggregation level of each terminal.
As an embodiment, different CCEs may be used for the purpose of frequency division, for example: when the aggregation level l=8, the PDCCH may be sent to UE1 on CCEs 0-7 and to UE2 on CCEs 16-23; as another embodiment, different aggregation levels may be used for frequency division purposes, for example: the UE1 aggregation level l=8 may send PDCCH to UE1 on CCEs 0-7, and the UE2 aggregation level l=16 may send PDCCH on CCEs 16-31.
In the above scheme, the downlink interference isolation is smaller than the first threshold value and the uplink interference isolation is not smaller than the second threshold value, so that the interference between the service beam and other beams is represented, and therefore the service beam and other beams can be subjected to frequency division scheduling by selecting the PDCCH with non-collision frequency domain, and the interference between the service beam and other beams is avoided. Wherein, the dispatching terminal is not directly stopped when the interference is perceived, so the uplink and downlink throughput of the user is not affected.
Further, on the basis of the foregoing embodiment, when the downlink interference isolation between the service beam and the other beams is smaller than the first threshold and the uplink interference isolation between the service beam and the other beams is smaller than the second threshold, if the channels corresponding to the service beam and the other beams include PDCCH and PUSCH, the step S102 may specifically include the following steps:
Step 1), if the downlink interference isolation between the service beam and other beams is smaller than a first threshold value and the uplink interference isolation between the service beam and other beams is smaller than a second threshold value, judging whether the PUSCH and the PDCCH can perform frequency division scheduling.
Step 2), if the PUSCH and the PDCCH can perform frequency division scheduling, selecting the PUSCH and the PDCCH which do not collide in the frequency domain to perform frequency division scheduling on the service beam and other beams.
Specifically, in step 1), when the downlink interference isolation between the service beam and the other beams is smaller than the first threshold, and the uplink interference isolation between the service beam and the other beams is smaller than the second threshold, it may be further determined whether the corresponding channels can perform frequency division scheduling. When the channel cannot be subjected to frequency division scheduling, the target terminal cannot be scheduled; when the channel can be frequency division scheduled, the service beam and other beams can be frequency division scheduled.
In the embodiment of the application, channels corresponding to the service beam and other beams can comprise PDCCH and PUSCH; at this time, it can be determined whether or not the PDCCH and PUSCH can be frequency division scheduled.
In the step 2), if the PDCCH and PUSCH can perform frequency division scheduling, the service beam and other beams can be scheduled; specifically, a PDCCH and a PUSCH that do not collide in the frequency domain may be selected to frequency-division schedule traffic beams and other beams.
For PDCCH, for example, please refer to fig. 3, fig. 3 is a schematic diagram of PDCCH detection space configured by different terminals according to an embodiment of the present application, wherein ms (monitoring space) represents a detection space of a Control channel unit (Control CHANNEL ELEMENT, CCE) of the terminal at the aggregation level, and a coloring area is a search space for detecting PDCCH corresponding to the aggregation level of each terminal.
As an embodiment, different CCEs may be used for the purpose of frequency division, for example: when the aggregation level l=8, the PDCCH may be sent to UE1 on CCEs 0-7 and to UE2 on CCEs 16-23; as another embodiment, different aggregation levels may be used for frequency division purposes, for example: the UE1 aggregation level l=8 may send PDCCH to UE1 on CCEs 0-7, and the UE2 aggregation level l=16 may send PDCCH on CCEs 16-31.
For PUSCH, for PDSCH, PRBs may be aggregated into RBGs, and the RBGs used for this scheduling may be indicated by means of bitmap. As an embodiment, the frequency division of the continuous RBG may be used for the purpose of frequency division, for example: referring to fig. 4, fig. 4 is a schematic diagram of a PDSCH/PUSCH frequency division manner provided by an embodiment of the present application, where a coloring area in fig. 4 indicates RBGs corresponding to the UE, that is, UE1 uses RBGs 0 to 7 and UE2 uses RBGs 8 to 16; as another embodiment, the purpose of frequency division can be achieved by shifting RBGs with respect to each other, for example: referring to fig. 5, fig. 5 is a schematic diagram of another PDSCH/PUSCH frequency division method provided by the embodiment of the present application, and the colored region in fig. 5 also indicates an RBG corresponding to the UE, that is, the RBG is used by UE 1: 1/3/5/7/9/11/13/15, ue2 uses RBG:0/2/4/6/8/10/12/14/16.
In the above scheme, the downlink interference isolation is smaller than the first threshold value and the uplink interference isolation is smaller than the second threshold value, so that interference between the service beam and other beams is represented, and therefore the service beam and other beams can be subjected to frequency division scheduling by selecting the PUSCH and the PDCCH which do not collide in the frequency domain and performing frequency division scheduling on the service beam and other beams, and interference between the service beam and other beams is avoided. Wherein, the dispatching terminal is not directly stopped when the interference is perceived, so the uplink and downlink throughput of the user is not affected.
Referring to fig. 6, fig. 6 is a flowchart of a co-channel interference avoidance process under a downlink scheduling situation according to an embodiment of the present application, where a threshold a and a threshold B are used to represent a first threshold and a second threshold respectively.
1. When downlink interference isolation > =threshold a, and uplink interference isolation > =threshold B: the downstream beam is directed to the terminal for scanning and scheduling.
2. When downlink interference isolation > =threshold a, and uplink interference isolation < threshold B: (1) If the non-HARQ scheduling is performed, the terminal is still pointed to scan and schedule; (2) If the HARQ scheduling is performed, HARQ feedback resources which are different from the previous time slot scheduling are selected, the terminal is pointed to scan and schedule, and if the HARQ feedback resources have conflict, the terminal is not scheduled.
3.
