Technical Field

Background

The 5G network not only greatly changes the existing life and working modes of people, improves the communication efficiency, but also can increase the possibility that a plurality of leading-edge technologies and products fall to the ground.

In a conventional method, a base station device in a 5G network may schedule available uplink resources for a User Equipment (User Equipment, abbreviated as UE). For a Physical Uplink Control Channel (PUCCH) resource, the base station device may pre-configure 4 PUCCH resource sets for the UE. When the base station equipment schedules the PUCCH resources for the UE, one resource set can be selected from the 4 PUCCH resource sets, and the available PUCCH resources can be randomly determined from the selected PUCCH resource set, so that the UE can send uplink control messages to the base station equipment through the PUCCH resources.

However, the adoption of the method causes the PUCCH resource set to generate more resource fragments, so that the PUCCH resource set configured by the base station needs to occupy more frequency spectrum resources to meet the resource scheduling requirement of the UE; the more resources occupied by PUCCH resources in the limited Uplink resources, the less available Uplink Physical Shared Channel (PUSCH) resources, which results in a decrease in the transmission rate of Uplink data.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The resource scheduling method provided by the present application can be applied to the application environment shown in fig. 1, where the base station 100 is in communication connection with the terminal device 200. The terminal 200 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, portable wearable devices, and the like. The Base Station may be, but not limited to, a macro Base Station, a micro Base Station, a small Base Station, and other types of Base Station devices, and may be a Base Station (BTS) in Global System for Mobile communication (GSM) or Code Division Multiple Access (CDMA), a Base Station (NodeB) in Wideband Code Division Multiple Access (WCDMA), an evolved Node B (eNB) or eNodeB) in LTE, a relay Station or Access point, a Base Station in a future 5G network, a Customer Premise Equipment (CPE), and the like, and is not limited herein.

In an embodiment, as shown in fig. 2, a resource scheduling method is provided, which is described by taking the application of the method to the base station device in fig. 1 as an example, and includes:

s101, selecting a target PUCCH resource set from a plurality of uplink control channel PUCCH resource sets which are pre-configured for target User Equipment (UE); the PUCCH resources in the target PUCCH resource set are distributed over multiple frequency bands.

The target UE may be a device that waits for the base station device to allocate resources in the current scheduling period, and may be, but is not limited to, various personal computers, laptops, smartphones, tablets, portable wearable devices, and the like.

The base station device may configure a plurality of PUCCH resource sets in advance for the target UE, where the PUCCH resource sets may include available PUCCH resources, and sizes of PUCCH resources included in the PUCCH resource sets may be the same or different. For example, the PUCCH resources included in the plurality of PUCCH resource sets each have a size of 32 resource blocks.

The PUCCH resource set may be dedicated to the target UE, or may be shared by a plurality of UEs accessing to a cell in which the base station device is located. The number of PUCCH resource sets corresponding to different UEs may be the same or different. For example, each UE accessing the cell corresponds to 4 PUCCH resource sets.

The base station can determine the PUCCH resource set of the target UE according to the identification of the UE. The Identifier may be an International Mobile Equipment Identity (IMEI) of the user Equipment, may also be a Unique Equipment Identity (UDID) of the user Equipment, and may also be a universal Unique Identity (UUDI), which may uniquely identify the user Equipment, and the type of the Identifier is not limited herein. After identifying the UE to be scheduled, the base station may determine, according to the configuration information, a plurality of PUCCH resource sets configured for the UE.

After determining a plurality of PUCCH resource sets corresponding to the target UE, the base station device may select one PUCCH resource set from the plurality of PUCCH resource sets as the target PUCCH resource set. Specifically, the base station device may randomly select a target PUCCH resource set from a plurality of PUCCH resource sets, or may select a target PUCCH resource set from the plurality of PUCCH resource sets according to the size of a PUCCH resource required by the target UE; in addition, the base station can also determine the size of idle resources in the plurality of PUCCH resource sets in sequence according to the arrangement sequence of the plurality of PUCCH resource sets, and determine a set with the size of the idle resources meeting the requirements of the target UE as a target PUCCH resource set; the determination method of the target PUCCH resource set is not limited herein.

In the target PUCCH resource set determined by the base station device, PUCCH resources may be distributed over multiple frequency bands. The plurality of frequency bands are located within an operating frequency band of the target device. The plurality of frequency bands may be adjacent frequency bands, or may have a certain frequency interval, which is not limited herein.

S102, acquiring the number of the UE of the cell where the current access target UE is located.

The base station device may obtain the number of UEs currently accessing the cell in the cell where the target UE is located. The types of the UE devices corresponding to the UE number may be the same or different, and the UE devices may be accessed to the cell. The UE device corresponding to the UE quantity may be a device in which the base station device has already scheduled the PUCCH resource, or a device in which the base station device is to schedule the resource, and is not limited herein.

S103, determining a target frequency band in the multiple frequency bands according to the number of the UE.

On the basis of the above steps, the base station device may determine the target frequency band among the plurality of frequency bands according to the number of UEs. The base station device may configure a corresponding relationship between the number of UEs and the frequency bands, and after acquiring the number of UEs, the base station device may determine the frequency bands corresponding to the number of UEs as target frequency bands.

The base station determines a target frequency band according to the number of the UE, so that PUCCH resources corresponding to part of the UE which is initially accessed to the base station can be on the same frequency band; with the increase of the number of UEs accessing the base station, after the PUCCH resource in the previous frequency band is scheduled, the base station may start scheduling the PUCCH resource for the newly accessed UE in the next frequency band. For example, the first 10 UEs accessing the base station correspond to the first frequency band, and the 11 th to 20 th UEs accessing the base station correspond to the second frequency band.

And S104, searching a target PUCCH resource in the target PUCCH resource set by taking the target frequency band as an initial searching frequency band, and sending resource scheduling information to the target UE based on the searched target PUCCH resource.

After determining the target frequency band, the base station may search for the target PUCCH resource for the target UE in the target PUCCH resource set with the frequency band as an initial search frequency band.

Specifically, the base station device may search for an idle resource in the target frequency band, and if the size of the PUCCH resource centrally distributed in the idle resource matches the size of the PUCCH resource required by the target UE, may determine the idle resource as the target PUCCH resource; or, the base station device may also schedule a target PUCCH resource for the target UE in the target frequency band according to the frequency arrangement order; the determination method of the target PUCCH resource is not limited herein.

If the base station device does not search the PUCCH resource satisfying the condition on the target frequency band, the base station device may search the target PUCCH resource on the other frequency bands except the target frequency band among the plurality of frequency bands according to the preset frequency band sequence. The preset frequency band sequence may be arranged in frequency size, or may be arranged in frequency band identifier, which is not limited herein. For example, PUCCH resources in the target PUCCH resource set are distributed on the first frequency band and the second frequency band, and if the first frequency band is the target frequency band, the base station device may search for available PUCCH resources in the PUCCH resources on the first frequency band by using the first frequency band as an initial search frequency band, and use the PUCCH resources as the target PUCCH resources; if the base station device does not search for a PUCCH resource satisfying the condition in the first frequency band, the base station may continue to search for an available PUCCH resource in the second frequency band.

After determining the target PUCCH resource, the base station device may indicate a resource scheduling message of the target PUCCH resource to the UE, so that the UE may send an uplink control message through the target PUCCH resource. The uplink control message may be HARQ-ACK feedback sent by the UE to the base station device, an uplink Scheduling Request (SR) sent by the base station device, or Channel Status Information (CSI) sent by the UE to the base station.

If the base station device does not search the target PUCCH resource in the multiple frequency bands, the base station device may return to execute the resource scheduling method in the next scheduling period, and reschedule the PUCCH resource for the target UE.

In the resource scheduling method, the base station selects a target PUCCH resource set from a plurality of uplink control channel PUCCH resource sets which are configured for target user equipment UE in advance; then, acquiring the number of UE of a cell where the current access target UE is located, and determining a target frequency band on a plurality of frequency bands in a target PUCCH resource set according to the number of the UE; and finally, the base station takes the target frequency band as an initial searching frequency band, searches the target PUCCH resource in the target PUCCH resource set, and sends resource scheduling information to the target UE based on the searched target PUCCH resource. The PUCCH resources in the target PUCCH resource set are distributed on a plurality of frequency bands, and the base station can select the target frequency bands on the plurality of frequency bands according to the number of the UE currently accessed into the cell, so that the base station can intensively distribute the PUCCH resources according to the number of the UE, a large amount of resource fragments generated in the PUCCH resource set due to the fact that the distributed PUCCH resources are randomly distributed on the plurality of frequency bands are avoided, and the PUCCH resources scheduled for each target UE by the base station are more compact; furthermore, the base station can intensively schedule the PUCCH resources in the PUCCH resource set, so that the PUCCH resource set configured by the base station can occupy less spectrum resources to meet the PUCCH resource scheduling requirement of the target UE, so that more available PUSCH resources are available, and the transmission rate of uplink data transmitted by the PUSCH resources can be increased.

Fig. 3 is a schematic flow chart of a resource scheduling method in another embodiment, which relates to a manner for a base station device to determine a target frequency band, where, on the basis of the embodiment, the multiple frequency bands include a first frequency band and a second frequency band, and as shown in fig. 3, the S103 includes:

s201, comparing the number of the used UE with a preset number threshold value to obtain a comparison result.

After the base station device determines the target PUCCH resource set, PUCCH resources in the PUCCH resource set may be distributed over the first frequency band and the second frequency band. The base station device may compare the number of UEs with a preset number threshold, and obtain a comparison result. The comparison result may be that the number of UEs is greater than, equal to, or less than the number threshold; alternatively, the number threshold may include a plurality of thresholds, the plurality of thresholds may form a plurality of interval ranges, and the comparison result may be that the current number of UEs belongs to which interval range formed by the number threshold; the form of the comparison result is not limited herein.

S202, according to the comparison result, one frequency band is selected from the first frequency band and the second frequency band to serve as a target frequency band.

Further, the base station device may select one frequency band from the first frequency band and the second frequency band as the target frequency band according to the comparison result.

In an application scenario, since the PUCCH resource of the UE may relate to a frequency hopping signal, the PUCCH resource in the PUCCH resource set may be centrally distributed at two ends of the operating frequency band of the UE. Therefore, the first band and the second band may be bands at both ends of the target UE operating band, the first band may be lower than the second band, for example, the operating band of the target UE may be { f1, f2}, the first band may be { f1, f1+ fc }, and the second band may be { f2-fc, f2 }. Optionally, in a case that the comparison result is that the number of UEs is greater than, equal to, or less than the number threshold, the base station device may determine the first frequency band as the target frequency band when the number of UEs is less than the number threshold; and determining the second frequency band as the target frequency band when the comparison result shows that the number of the UE is greater than or equal to the number threshold.

According to the resource scheduling method, the base station equipment can quickly determine the target frequency band corresponding to the target UE according to the preset number threshold, so that the PUCCH resources can be scheduled on the target frequency band, the PUCCH resource scheduling efficiency is higher, and the data transmission delay between the base station and the UE is further reduced.

When the base station equipment searches the PUCCH resources on the target frequency band, the fragment resources in the PUCCH resource set can be reduced as much as possible, and the utilization rate of the PUCCH resource set is improved to the maximum extent. In the following two embodiments, determination manners of determining the target PUCCH resource in the target PUCCH resource set by the base station device are respectively described.

Fig. 4 is a flowchart of a resource scheduling method in another embodiment, where this embodiment relates to a manner in which a base station device determines a target PUCCH resource, and on the basis of the foregoing embodiment, as shown in fig. 4, the foregoing S104 includes:

s301, inquiring the distribution information of the allocated PUCCH resources corresponding to the target PUCCH resource set.

The allocated PUCCH resources may be PUCCH resources scheduled for other UEs in the target PUCCH resources; the PUCCH resource may also be a PUCCH resource scheduled for the last UE in the current scheduling period, which is not limited herein.

After scheduling the PUCCH resource for each UE, the base station device may record and store the position of the scheduled PUCCH resource, so that the base station may obtain the distribution information of the allocated PUCCH resource.

And S302, determining the PUCCH resource which is most adjacent to the allocated PUCCH resource as the target PUCCH resource according to the distribution information.

Further, the base station device may determine, according to the distribution information, a position of the allocated PUCCH resource in the target PUCCH resource set; further, the base station apparatus may determine an available PUCCH resource closest to the allocated PUCCH resource as a target PUCCH resource. The frequency of the target PUCCH resource may be greater than the allocated PUCCH resource or smaller than the allocated PUCCH resource, which is not limited herein.

According to the resource scheduling method, the base station equipment determines the target PUCCH resource at the position closest to the allocated PUCCH resource based on the distribution information of the allocated PUCCH resource, so that resource fragments in the target PUCCH resource set can be effectively reduced, and the utilization rate of the target PUCCH resource is further improved.

In an embodiment, the present invention relates to a method for determining a target PUCCH resource by a base station device, where on the basis of the foregoing embodiment, if a target frequency band is a first frequency band, an available PUCCH resource is selected from PUCCH resources corresponding to the first frequency band as the target PUCCH resource from the lowest frequency of the first frequency band; and if the target frequency band is the second frequency band, starting from the highest frequency of the second frequency band, screening available PUCCH resources from PUCCH resources corresponding to the second frequency band as target PUCCH resources.

According to the resource scheduling method, the base station equipment can start to schedule PUCCH resources from two ends of the working frequency band of the target UE, so that the scheduled PUCCH resources can be distributed at the two ends of the working frequency band and are far away from PUSCH resources in the middle of the working frequency band; when the PUSCH resources are insufficient, the PUCCH resources close to the PUSCH resources in the PUCCH resource set can be redistributed and adjusted to the PUSCH resources for transmitting uplink data, so that the uplink data transmission requirement is met, and the uplink data transmission rate is improved. In addition, after the base station device determines the target frequency band, the base station device screens available resources in the target PUCCH resource set from the lowest frequency of the first frequency band or the highest frequency of the second frequency band, so that the fragment resources generated in the allocated PUCCH resources can be reused, and the utilization rate of the PUCCH resource set is improved.

Fig. 5 is a flowchart illustrating a resource scheduling method in another embodiment, where this embodiment relates to a manner in which a base station device determines a target PUCCH resource set, and on the basis of the foregoing embodiment, as shown in fig. 5, the foregoing S101 includes:

s401, based on the service data to be scheduled of the target UE, determining the bit number of the uplink control information UCI of the target UE.

In the downlink scheduling process, after determining downlink to-be-scheduled service data of a target UE, a base station may determine, according to a service type of the to-be-scheduled service data and a data size of the service data, a bit number of Uplink Control Information (UCI) corresponding to the service data.

S402, selecting a target PUCCH resource set from the PUCCH resource sets according to the bit number of the UCI and a preset bit number threshold.

Further, the base station device may compare the bit number of the UCI with a preset bit number threshold, and select a target PUCCH resource set from the plurality of PUCCH resource sets. For example, the PUCCH resources included in the plurality of PUCCH resource sets have different sizes, and the base station apparatus may select, when the number of UCI bits is large, a resource set with a large number of PUCCH resources from the plurality of PUCCH resource sets as the target PUCCH resource set.

Optionally, the base station device may further select a PUCCH resource set with a transmission rate matching according to the number of bits of the UCI. The base station device may configure a transmission rate for each PUCCH resource set, where the transmission rates corresponding to different PUCCH resource sets are different. Different UCI bit numbers need to match different transmission rates, and the larger the UCI bit number is, the higher the transmission rate is needed. The base station equipment compares the bit number of the UCI with a bit number threshold value, and determines a target bit number interval corresponding to the bit number of the UCI; then, according to the interval resource corresponding relation, determining a PUCCH resource set corresponding to the target bit number interval as a target PUCCH resource set; in the interval resource corresponding relation, bit number intervals correspond to PUCCH resource sets one by one, and the value of the bit number interval is positively correlated to the transmission rate of the PUCCH resource sets.

For example, the base station device configures 4 PUCCH resource sets for the target UE, where the 4 PUCCH resource sets are arranged in order of increasing transmission rate. When the number of bits of the UCI is less than or equal to the first bit number threshold, the base station device may determine the first PUCCH resource set as a target PUCCH resource set; when the bit number of the UCI is greater than the first bit number threshold and is less than or equal to the second bit number threshold, the base station device may determine the second PUCCH resource set as the target PUCCH resource set; when the bit number of the UCI is greater than the second bit number threshold and is less than or equal to a third bit number threshold, the base station device may determine a third PUCCH resource set as the target PUCCH resource set; when the bit number of the UCI is greater than the third bit number threshold, the base station device may determine the fourth PUCCH resource set as the target PUCCH resource set.

According to the resource scheduling method, the base station equipment determines the target PUCCH resource set according to the bit number of the UCI, so that the transmission rate of the PUCCH resources in the target PUCCH resource set can meet the transmission requirement of the target UE, and the scheduling of the PUCCH resources is more reasonable.

Fig. 6 is a flowchart illustrating a resource scheduling method in another embodiment, where this embodiment relates to a manner in which a base station device configures multiple PUCCH resource sets, and on the basis of the foregoing embodiment, as shown in fig. 6, before the foregoing S101, the method further includes:

s501, determining the collection number of PUCCH resource sets corresponding to the target UE according to the number of the service types supported by the target UE.

The target UE may correspond to multiple service types, and the service types may include a call service, a data download service, an internet access service, a live broadcast service, and the like. The base station device may obtain the number of service types supported by the target UE. Further, the base station device may determine the number of sets of PUCCH resource sets corresponding to the target UE according to the number of service types supported by the target UE. In order to meet the scheduling requirements of different services, when the number of service types supported by the target UE is large, the number of PUCCH resource sets configured for the target base station by the base station device is large.

Optionally, the base station device may compare the number of the service types supported by the target UE with a preset service number threshold, and determine the number of sets of PUCCH resource sets corresponding to the target UE according to the comparison result. If the number of the service types is smaller than or equal to a first service number threshold value, determining the set number of the PUCCH resource sets corresponding to the target UE as a first numerical value; if the number of the service types is larger than the first service number threshold and smaller than or equal to the second service number threshold, determining the collection number of the PUCCH resource sets corresponding to the target UE as a second numerical value; if the number of the service types is larger than a second service number threshold value, determining the set number of the PUCCH resource set corresponding to the target UE as a third numerical value; wherein the second value is greater than the first value and the third value is greater than the second value.

S502, selecting a plurality of PUCCH resource sets matched with the set number from a plurality of preset candidate PUCCH resource sets.

After determining the number of sets, the base station device may configure, for the target UE, multiple PUCCH resource sets that match the number of sets, among multiple candidate PUCCH resource sets configured in the current cell. For example, when the number of sets is 3, the base station apparatus may select 3 PUCCH resource sets from the candidate PUCCH resource sets as PUCCH resource sets available to the target UE.

Specifically, the base station device may randomly select a plurality of PUCCH resource sets matching the set number from the plurality of candidate PUCCH resource sets, or may select the PUCCH resource sets according to the arrangement order of the candidate PUCCH resource sets, which is not limited herein. For example, when the base station selects 2 PUCCH resource sets from 4 candidate PUCCH resource sets, the base station may randomly select the first PUCCH resource set and the fourth PUCCH resource set, or may select the first PUCCH resource set and the second PUCCH resource set as PUCCH resource sets available to the target UE according to the configured transmission rate permutation order.

S503, indicating configuration information of a plurality of PUCCH resource sets to the target UE through a radio resource control RRC message.

After configuring a plurality of PUCCH Resource sets for the target UE, the base station may send configuration information of the plurality of PUCCH Resource sets to the target UE through a Radio Resource Control (RRC) message.

According to the resource scheduling method, the base station equipment determines the number of the PUCCH resource sets corresponding to the target UE according to the number of the service types supported by the target UE, so that the base station can more reasonably configure the PUCCH resource sets for the target UE, more uplink resources are released for uplink data transmission, and the transmission rate of uplink data is improved.

Fig. 7 is a flowchart illustrating a resource scheduling method in another embodiment, where this embodiment relates to a manner in which a base station releases a PUCCH resource set, and on the basis of the foregoing embodiment, as shown in fig. 7, after S104, the method further includes:

s601, according to the downlink scheduling time slot configured for the target UE, determining a scheduling window of the uplink physical shared channel (PUSCH) resource corresponding to the target PUCCH resource in the current scheduling period.

In downlink scheduling, PUCCH resources corresponding to PUSCH resources of multiple different slots may all be scheduled on the same resource. The PUSCH resources of the plurality of different slots may be referred to as a scheduling window of the PUCCH resources. The base station device may determine a downlink feedback delay range according to the downlink scheduling timeslot configured for the target UE, and further determine a scheduling window corresponding to the target PUCCH resource according to the downlink feedback delay range. For example, the target PUCCH resource is located in slot 8; according to the range of downlink feedback delay, the scheduling window may be from time slot 2 to time slot 6; the downlink data sent by the base station through the time slots 2 to 6 may be scheduled to be fed back on the target PUCCH resource.

S602, after the PUSCH resources of each time slot in the scheduling window are scheduled, determining that the target PUCCH resources meet the release condition.

After the PUSCH resources of each time slot in the scheduling window are all scheduled, the base station device may consider that the target UE has already completed uplink feedback corresponding to each downlink data in the scheduling window, and the target UE does not need to send uplink control information through the target PUCCH resources in the current scheduling time slot. Accordingly, the base station apparatus may determine that the target PUCCH resource satisfies the release condition.

After the base station equipment releases the target PUCCH resource, the target PUCCH resource can be called by other UE, and the utilization rate of the PUCCH resource is improved.

Further, if the scheduled target PUCCH resources all meet the release condition, emptying the PUCCH resource scheduling result stored in the current scheduling period; the PUCCH resource scheduling result comprises PUCCH resource scheduling information of all target UEs accessing the cell.

According to the resource scheduling method, the base station equipment selects the scheduling result of emptying the PUCCH resources once at a moment in the current scheduling period, so that the problem that the system processing data volume is large due to emptying once every scheduling can be avoided, and the system computing resources are saved.

It should be understood that although the various steps in the flow charts of fig. 2-7 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.
