Description

Resource scheduling method, device, base station, user equipment and storage medium

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a resource scheduling method, a device, a base station, a user equipment, and a storage medium.

Background

With the development of communication technology, three service types can be supported in a fifth Generation mobile communication (5 th-Generation, abbreviated as 5G) system, including: in order to effectively shorten the time delay from a base station to receiving uplink feedback, physical uplink control channel (Physical Uplink Control Channel, PUCCH) resource scheduling in a 5G system can support a sub-slot scheduling function, that is, the time interval between the base station transmitting downlink service data and the uplink feedback of a receiving User Equipment (UE) can be in units of sub-slots, so that the base station can schedule PUCCH resources for the UE in one slot.

In the conventional method, the base station may inform the UE of the PUCCH sub-slot length used by the UE through a radio resource control (Radio Resource Control, abbreviated RRC) reconfiguration message. The PUCCH sub-slot length relates to the uplink coverage of the UE, and the shorter the PUCCH sub-slot length is, the smaller the uplink coverage of the UE is. When the PUCCH sub-slot length cannot meet the uplink coverage requirement, the base station needs to re-indicate the new PUCCH sub-slot length to the UE through the RRC reconfiguration message.

However, the above method leads to too long time for the base station to adjust the PUCCH sub-slot length, which affects the transmission of uplink control information.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.

The resource scheduling method provided by the application can be applied to an application environment shown in fig. 1, and the base station 100 is in communication connection with the user equipment 200. The user device 200 may be, but is 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 equipment, and the base station 100 may be, but not limited to, a base station in a 5G network, a customer premise equipment (Customer Premise Equipment, abbreviated CPE), and the like.

In one embodiment, as shown in fig. 2, a resource scheduling method is provided, and an example of application of the method to the base station in fig. 1 is described, including:

S101, determining indication information of a target PUCCH sub-slot length adopted in next service scheduling according to transmission quality of Physical Uplink Control Channel (PUCCH) data sent by User Equipment (UE).

The PUCCH data may be HARQ-ACK feedback sent by the UE to the base station, an uplink scheduling request (Scheduling Request, abbreviated as SR) sent by the UE to the base station, channel condition information (Channel Status Information, abbreviated as CSI) sent by the UE to the base station, or the like. The transmission quality of the PUCCH data may be obtained by detecting the PUCCH data by the base station, or may be obtained by transmitting a detection signal in the PUCCH channel by the base station, which is not limited herein. The transmission quality may be a signal-to-noise ratio (Signal to Interference plus Noise Ratio, abbreviated SINR) of the PUCCH data, or a block error rate (Block Error Ratio, abbreviated BLER) of the PUCCH data, and the type of the transmission quality is not limited herein.

The PUCCH sub-slot length refers to a time unit of a time interval used when the base station configures a PUCCH resource for the UE. The PUCCH sub-slot length may be 2 symbols, 4 symbols, or 7 symbols, which is not limited herein. Of course, the PUCCH sub-slot length may also be identical to the slot length, for example, the PUCCH sub-slot length is 14 symbols. After configuring the PUCCH sub-slot length for the UE, the base station may use the PUCCH sub-slot length as a unit in a time interval from downlink data indicated to the UE to feedback PUCCH data when scheduling downlink traffic for the UE through downlink control signaling (Downlink Control Information, DCI for short); for example, the base station configures a PUCCH sub-slot length for the UE to be 2 symbols, indicates the UE to return PUCCH data after K1 PUCCH sub-slot lengths through DCI, and the UE may transmit PUCCH data after 2×k1 symbols.

The indication information of the PUCCH sub-slot length is used by the base station to indicate to the UE the size of the PUCCH sub-slot length to be adopted, and the indication information may be the number of symbols of the PUCCH sub-slot length, or may be an identifier corresponding to the PUCCH sub-slot length, which is not limited herein.

Since the PUCCH sub-slot length is related to the uplink coverage of the UE. The base station can select a larger PUCCH sub-slot length as the target PUCCH sub-slot length under the condition that the current PUCCH transmission quality is poor. The base station can compare the transmission quality of the current PUCCH data with the transmission quality of the PUCCH data obtained in the previous scheduling, determine the target PUCCH sub-slot length adopted in the next scheduling, and further determine the indication information of the PUCCH sub-slot length according to the corresponding relation between the PUCCH sub-slot length and the indication information; optionally, the base station may compare the transmission quality with a preset transmission quality threshold, and determine the indication information of the target PUCCH sub-slot length.

S102, transmitting downlink control signaling DCI to UE; the DCI carries indication information, and is used for indicating the UE to select target PUCCH configuration parameters matched with the indication information from a plurality of preset PUCCH configuration parameters based on the indication information, and determining target PUCCH resources of the service based on the target PUCCH sub-slot length in the target PUCCH configuration parameters; the PUCCH sub-slot lengths contained in the different PUCCH configuration parameters are different.

The base station can schedule PUCCH resources for the UE through DCI, and can adopt different DCI formats according to different service types; alternatively, the same DCI format may be used to schedule different traffic types. The service type may be one of enhanced mobile broadband (Enhanced Mobile Broad Band, eMBB) service and Ultra-high reliability and low latency communication (Ultra-reliable and Low Latency Communications, URLLC) service. The enhanced mobile broadband eMBB service is realized by adopting a larger bandwidth and improving the baseband rate, and a higher transmission rate is realized, and is mainly used for high-speed data, high-definition video and other services. The above URLLC service pursues lower latency and higher reliability, and needs to implement extremely short latency by means of faster scheduling, which is mainly used for services such as internet of vehicles and remote control.

The DCI carries indication information related to the target PUCCH sub-slot length, so that the UE can determine the size of the PUCCH sub-slot length based on the indication information; the indication information may be a value of a priority indication field (Priority indicator) in the DCI. Alternatively, in the case of the priority indication field value acknowledgement in DCI, the indication may be indicated by a specific format of DCI, such as indicating the sub-slot length configured in the first PUCCH with DCI format 1_1, and DCI format 1_2 indicating the sub-slot length configured in the second PUCCH.

The notification method of the sub-slot length may be notified by a MAC CE instead of the DCI method, alternatively. The MAC CE carries indication information related to the target PUCCH sub-slot length, so that the UE may determine the size of the PUCCH sub-slot length based on the indication information.

Multiple PUCCH configuration parameters may be preset in the UE, and PUCCH sub-slots included in different PUCCH configuration parameters have different lengths. The PUCCH configuration parameters described above are used to determine available PUCCH resources for the UE. After the UE acquires the indication information in the DCI, a target PUCCH configuration parameter corresponding to the indication information may be selected from the plurality of PUCCH configuration parameters according to a correspondence between the indication information and the PUCCH configuration parameter, so as to acquire a target PUCCH sub-slot length in the target PUCCH configuration parameter. The base station may simultaneously configure the plurality of PUCCH configuration parameters by sending the high-layer signaling once, or may send the high-layer signaling multiple times, so that the UE obtains the plurality of PUCCH configuration parameters, which is not limited herein.

The DCI may further include a location of a downlink shared physical channel (Physical Downlink Share CHannel, abbreviated PDSCH) resource carrying downlink data, and a time interval K1 between the PDSCH and a PUCCH resource where the UE returns PUCCH data. After receiving the DCI, the UE can receive downlink data in the PDSCH resource, and demodulate the downlink data to obtain uplink feedback PUCCH data, such as HARQ-ACK codebook; further, the UE may determine, according to the target PUCCH sub-slot length and the time interval K1, a location where the target PUCCH resource is located, determine the target PUCCH resource from available PUCCH resources corresponding to the target PUCCH configuration parameter, and send the HARQ-ACK codebook through the target PUCCH resource.

According to the resource scheduling method, the base station determines the indication information of the target PUCCH sub-slot length adopted in next scheduling service according to the transmission quality of Physical Uplink Control Channel (PUCCH) data sent by the User Equipment (UE); then, sending downlink control signaling DCI to the UE; the DCI carries indication information, and is used for indicating the UE to select target PUCCH configuration parameters matched with the indication information from a plurality of preset PUCCH configuration parameters based on the indication information, and determining target PUCCH resources of the service based on the target PUCCH sub-slot length in the target PUCCH configuration parameters; the PUCCH sub-slot lengths contained in the different PUCCH configuration parameters are different. The base station can determine the target PUCCH sub-slot length which is used when the service is scheduled next time according to the transmission quality of PUCCH data sent by the UE, so that the PUCCH sub-slot length can be adjusted in time according to the change of the transmission quality; further, as a plurality of PUCCH configuration parameters corresponding to the PUCCH sub-slot length are preset in the UE, the base station does not need to be configured again through the RRC reconfiguration message, but can indicate the indication information of the target PUCCH sub-slot length through DCI, the UE can determine the PUCCH resource according to the indication information, the adjustment duration of the PUCCH sub-slot is reduced, the smooth transmission of PUCCH data is ensured, and the reliability of data transmission is improved; in addition, by adopting the PUCCH sub-slot length to schedule PUCCH resources, the data transmission delay is reduced.

Fig. 3 is a flow chart of a resource scheduling method in an embodiment, where the present implementation relates to a manner in which a base station configures a plurality of PUCCH configuration parameters for a UE, and on the basis of the foregoing embodiment, as shown in fig. 3, the foregoing method further includes:

s201, a first capability query message is sent to UE; the capability query message is used for indicating the UE to return a first capability parameter; the first capability parameter includes at least one PUCCH sub-slot configuration supported by the UE.

The first capability parameter may be 11-3 capability of the UE, and the first capability query message may be UE capability requirement. The first capability parameter may include at least one PUCCH sub-slot configuration supported by the UE. The PUCCH sub-slot configuration may be used to determine a PUCCH sub-slot length of the UE, and the PUCCH sub-slot configuration may include a maximum number of symbols occupied by PUCCH resources of the UE and a symbol interval between two adjacent PUCCH resources of the UE. As shown in fig. 4, the shaded box in the figure may represent one PUCCH resource. The above PUCCH sub-slot configuration may be (4, 2), where 4 represents that the minimum distance between two adjacent PUCCH resources is greater than or equal to 4 OFDM symbols, and 2 represents that the PUCCH resources are 2 symbols at maximum. The PUCCH sub-slot configuration may be (7, 7), which means that the minimum distance between two adjacent PUCCH resources is greater than or equal to 7 symbols, and the PUCCH resources are 7 symbols at maximum. The PUCCH sub-slot configuration may be (2, 2), which means that the minimum distance between two adjacent PUCCH resources is greater than or equal to 2 symbols, and the PUCCH resources are 2 symbols at maximum.

The first capability parameter may include one PUCCH sub-slot configuration, may include 2 PUCCH sub-slot configurations, or may include 3 PUCCH sub-slot configurations, which is not limited herein. When the first capability parameter includes a plurality of PUCCH sub-slot configurations, any combination of PUCCH sub-slot configurations may be used. For example, the first capability parameters may be (2, 2) and (7, 7), may be (4, 2) and (7, 7), or may be (7, 7).

S202, receiving a first capability parameter returned by the UE based on the first capability query message.

After receiving the first capability query message, the UE may return the pre-stored first capability parameter to the base station, so that the base station may receive the first capability parameter.

S203, determining a plurality of PUCCH configuration parameters according to the first capability parameters; one PUCCH sub-slot configuration corresponds to one PUCCH configuration parameter.

Further, the base station may determine a plurality of PUCCH configuration parameters according to the first capability parameter. If the first capability parameter includes a plurality of PUCCH sub-slot configurations, the base station may determine a plurality of PUCCH sub-slot lengths according to the plurality of PUCCH sub-slot configurations, and then determine a PUCCH configuration parameter according to the plurality of PUCCH sub-slot lengths, respectively. If the first capability parameter includes one PUCCH sub-slot configuration, the base station may further determine one PUCCH sub-slot length according to the slot length when determining the plurality of PUCCH configuration parameters, and determine one PUCCH configuration parameter according to the PUCCH sub-slot length obtained based on the PUCCH sub-slot configuration and the PUCCH sub-slot length determined based on the slot length, respectively.

Optionally, the plurality of PUCCH configuration parameters includes a first PUCCH configuration parameter and a second PUCCH configuration parameter; if the first capability parameter includes two PUCCH sub-slot configurations, the base station determines a first PUCCH configuration parameter and a second PUCCH configuration parameter by using the maximum number of symbols in each PUCCH sub-slot configuration as the PUCCH sub-slot length. If the first capability parameter includes a PUCCH sub-slot configuration, the base station determines a first PUCCH configuration parameter by using the maximum number of symbols in the PUCCH sub-slot configuration as the PUCCH sub-slot length, and determines a second PUCCH configuration parameter by using the slot length as the PUCCH sub-slot length.

When the base station determines a plurality of PUCCH configuration parameters, the PUCCH configuration parameters also comprise PUCCH resource set configuration information matched with the PUCCH sub-slot length in the PUCCH configuration parameters; the PUCCH resource set configuration information is used to indicate a frequency domain range of a PUCCH resource corresponding to the PUCCH sub-slot length. The above-mentioned PUCCH resource set may include a plurality of PUCCH sets, and as shown in fig. 5, the base station may configure 4 PUCCH sets for the UE, including set0, set1, set2, and set3. In the same PUCCH resource, frequency domain ranges corresponding to different PUCCH sets are different. For different PUCCH sub-slot lengths, PUCCH resource sets corresponding to PUCCH resources in different time domain ranges are also different; when the length of the PUCCH sub-time slot is large, the frequency domain range occupied by the corresponding PUCCH resource set can be smaller; when the PUCCH sub-slot length is smaller, the frequency domain range occupied by its corresponding PUCCH resource set may be larger. The base station may include a correspondence between different PUCCH sub-slot lengths and configuration information of a PUCCH resource set, so that after the base station determines the PUCCH sub-slot length, the base station may obtain the configuration information of the PUCCH resource set corresponding to the PUCCH sub-slot length according to the correspondence.

In the above PUCCH configuration parameters, the PUCCH sub-slot length may be configured in a subslotLength fortpucch field, the starting symbol index of the available PUCCH resource may be configured in startingsymbol index, and the PUCCH resource set configuration information may be configured in PUCCH-resource. The above starting symbol index is used to indicate the starting position of the available PUCCH resource in the sub-slot, and as shown in fig. 6, the starting symbol index of the PUCCH resource PUCCH-i is 2 symbols. When the base station determines the available PUCCH resource based on the PUCCH sub-slot length, the length of the available PUCCH resource may be equal to the PUCCH sub-slot length or may be smaller than the PUCCH sub-slot length, which is not limited herein. For example, when the PUCCH sub-slot length is 7 symbols, the available PUCCH resource configured by the base station may be 4-7 symbols; when the PUCCH sub-slot length is 2 symbols, the available PUCCH resources configured by the base station may be 1-2 symbols.

In one application scenario, as shown in fig. 7, the first capability parameters of the UE received by the base station are (2, 2) and (7, 7). The base station may generate a first PUCCH configuration parameter for (2, 2) and a second PUCCH configuration parameter for (7, 7). In the first PUCCH configuration parameter, the subslotLengthForPUCCH may be configured to be 2 symbols, and PUCCH resource set configuration information matched with the 2 symbols may be configured in the PUCCH-resource, where the startingsymbol index is configured to use a sub-slot boundary as a reference. In the second PUCCH configuration parameter, the subslotLengthForPUCCH may be configured to 7 symbols, the PUCCH resource set configuration information matching with 7 symbols may be configured in the PUCCH-resource, and the startingsymbol index may be configured to 3 symbols.

In another application scenario, as shown in fig. 8, the first capability parameter of the UE received by the base station is (7, 7). The base station may generate a first PUCCH configuration parameter for (7, 7) and a second PUCCH configuration parameter for the slot length (14 symbols). In the first PUCCH configuration parameter, the subslotLengthForPUCCH may be configured to 7 symbols, and PUCCH resource set configuration information matched with 7 symbols may be configured in the PUCCH-resource set, where the startingsymbol index is configured to use a sub-slot boundary as a reference. In the second PUCCH configuration parameter, no subslotLengthfortpucch is configured, slot-level PUCCH resource set configuration information may be configured in the PUCCH-resource set, and the startingsymbol index is configured to 6 symbols.

S204, a plurality of PUCCH configuration parameters are sent to the UE through a radio control signaling RRC reconfiguration message.

After determining the plurality of PUCCH configuration parameters of the UE, the base station may send the plurality of PUCCH configuration parameters to the UE through an RRC reconfiguration message. The RRC reconfiguration message may further configure a plurality of codebook types, and a plurality of codebook types may be configured in the PDSCH-HARQ-ACK-codebook list, where the codebook types may correspond to PUCCH configuration parameters one by one. The multiple PUCCH configuration parameters and the multiple codebook types in the RRC reconfiguration message may be arranged randomly or may be arranged according to a priority order, for example, the first PUCCH configuration parameter in the RRC reconfiguration message is a low-priority PUCCH configuration parameter, and the corresponding first codebook type is a low-priority codebook type. The priority may correspond to the indication information, and when the indication information is a priority field in the DCI, the priority field in the DCI is 0 and corresponds to a low-priority PUCCH configuration parameter, and the priority field in the DCI is 1 and corresponds to a high-priority PUCCH configuration parameter.

The codebook types may be dynamic codebooks or semi-static codebooks, for example, default codebook types in the RRC reconfiguration message are all dynamic codebooks. After determining the target PUCCH resource based on the target PUCCH sub-slot length, the UE may generate an HARQ-ACK codebook according to a codebook type corresponding to the target PUCCH configuration parameter, and send the generated HARQ-ACK codebook to the base station through the target PUCCH resource.

According to the resource scheduling method, the base station can obtain at least one PUCCH sub-slot length corresponding to the UE through the first capability parameter of the UE, so that a plurality of PUCCH resource allocation parameters are determined according to the at least one PUCCH sub-slot length; further, the base station sends a plurality of PUCCH configuration parameters to the UE through the RRC reconfiguration message, so that the base station can dynamically adjust the PUCCH sub-slot length through the indication information of the DCI, the UE can determine target PUCCH resources by adopting the appropriate PUCCH sub-slot length, and smooth transmission of PUCCH data is ensured.

Fig. 9 is a flow chart of a resource scheduling method in an embodiment, where the present embodiment relates to a manner in which a base station transmits DCI, where the DCI includes a priority indication field, and a value of the priority indication field is indication information; on the basis of the above embodiment, as shown in fig. 9, the above S102 includes:

S301, sending a second capability query message to the UE; the second capability query message is used for indicating the UE to return a second capability parameter; the second capability parameter is used to characterize whether the UE supports updating of the value in the priority indication field.

The second capability parameter may be 11-4a capability of the UE, and the second capability query message may be the same as or different from the first capability query message. Optionally, the second capability query message may also be uecapabilityrequirement. The base station may obtain the first capability parameter and the second capability parameter of the UE by transmitting the UE capability requirement once.

The second capability parameter may be used to characterize whether a value in a priority indication field may be updated in a plurality of DCI formats of the UE, and the priority indication field may be a priority in the DCI for indicating that the UE transmits HARQ-ACK or PUSCH. The base station may send the indication information of the PUCCH sub-slot length through the priority indication field.

The DCI formats may include DCI formats 0_1/1_1/0_2/1_2. Different DCI formats correspond to different traffic types. For example, DCI format 1_1 may be used to schedule low priority EMBB traffic and DCI format 1_2 may be used to schedule high priority URLLC traffic.

S302, receiving a second capability parameter returned by the UE based on the second capability query message.

After receiving the second capability query message, the UE may return the pre-stored second capability parameter to the base station.

S303, selecting a DCI format adopted in next service scheduling according to the second capability parameter of the UE.

If the second capability parameter characterizes updating the value in the priority indication field supported by the UE, the base station may select a DCI format matching the scene type of the service, and write the indication information into the priority indication field of the DCI format. For example, when the currently scheduled service of the base station is a URLLC service, DCI format1_2 matching the URLLC service may be selected for scheduling, and the indication information may be written in the priority indication field in the DCI format 1_2.

And if the second capability parameter characterizes that the UE does not support updating of the value in the priority indication field, selecting a DCI format of which the value of the priority field is matched with the indication information. For example, the base station may indicate that the PUCCH sub-slot length is 7 symbols when the value of the priority field in the DCI is high priority, and indicate that the PUCCH sub-slot length is 2 symbols when the value of the priority field in the DCI is low priority. If the priority field in DCI format1_2 is high priority, the base station may indicate the PUCCH sub-slot length of 7 symbols using DCI format 1_2.

S304, the DCI is sent to the UE by adopting a DCI format.

Further, the base station may transmit DCI to the UE using the DCI format described above.

According to the resource scheduling method, the base station adopts the priority indication field in the DCI to send the indication information of the PUCCH sub-slot length, so that different priorities and different PUCCH sub-slot lengths can be corresponding; further, the base station selects a proper DCI format for scheduling according to the second capability parameter of the UE, so that the PUCCH sub-slot length of the UE can be changed in a dynamic mode of DCI, and the low-delay transmission requirement of the service is met.

In an embodiment, on the basis of the foregoing embodiment, the indication information of the target PUCCH sub-slot length is any one of first indication information and second indication information, and the PUCCH sub-slot length indicated by the first indication information is greater than the PUCCH sub-slot length indicated by the second indication information.

The transmission quality may be an SINR of the uplink control signaling, and if the SINR is smaller than a preset SINR threshold, the base station may determine that the indication information is the first indication information; and if the SINR is greater than or equal to a preset SINR threshold, determining the indication information as second indication information.

The transmission quality may also be the BLER of the uplink control signaling; if the BLER is greater than a preset BLER threshold, the base station can determine the indication information as first indication information; and if the BLER is smaller than or equal to a preset BLER threshold value, determining the indication information as second indication information.

For example, the first indication information is of low priority and the second indication information is of high priority. Among a plurality of PUCCH configuration parameters preset by the UE, the first PUCCH configuration parameter may be matched with a low priority, and the second PUCCH configuration parameter may be matched with a high priority. When the priority field carried in the DCI is high priority, the base station may determine a target PUCCH sub-slot length in the second PUCCH configuration parameter, and determine a target PUCCH resource from available PUCCH resources generated based on the second PUCCH configuration parameter.

When the base station initially schedules the UE, the priority field in the DCI may be set to low priority 0, to instruct the UE to determine the target PUCCH resource using a smaller PUCCH sub-slot length. When the base station monitors that the transmission quality of the uplink control signaling is poor, for example, the signal-to-noise ratio is low, a priority field in the DCI can be set to be high priority 1, and the UE is instructed to determine the target PUCCH resource by adopting a larger PUCCH sub-slot length.

According to the resource scheduling method, the base station dynamically adjusts the value of the PUCCH sub-slot length by monitoring the transmission quality of the uplink control signaling, so that the PUCCH sub-slot length can meet the transmission requirement of PUCCH data, and the transmission performance of the PUCCH data is improved.
