Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

In the description of the present invention, "/" means "or" unless otherwise specified, for example, a/B may mean a or B. "and/or" herein is merely an association relationship describing an associated object, and means that there may be three relationships, for example, a and/or B, and may mean: a exists alone, A and B exist simultaneously, and B exists alone. Further, "at least one" or "a plurality" means two or more. The terms "first", "second", and the like do not necessarily limit the number and execution order, and the terms "first", "second", and the like do not necessarily limit the difference.

MU-MIMO refers to the time-frequency resource that can be space-division multiplexed by multi-user equipment UE during uplink and downlink data transmission. As shown in fig. 1, UE1, UE2, UE3, and UE4 are paired UEs, and use the same time-frequency resource and utilize the near orthogonality of channels for space division multiplexing, so as to improve the cell capacity and spectral efficiency of uplink and downlink; the UE5 and the UE6 are not paired with other UEs, and independently occupy time-frequency resources for single-user MIMO.

When a plurality of UEs share time-frequency resources, the closer the channel between the UEs is to the orthogonality, the smaller the interference suffered by the UEs; it also relates to the SRS signal quality and channel correlation of the UE.

When the SRS signal quality of the UE is good and the correlation of the channels among the UE is small, the interference among the UE can be well eliminated, and the method is suitable for MU-MIMO pairing; when the SRS signal quality of the UE is poor (for example, SINR is low) or the channel correlation between UEs is strong, the interference between UEs cannot be well eliminated, and MU-MIMO may cause the throughput of the system to decrease instead.

In addition, in the existing MU-MIMO system, the factors such as the user service model difference are not fully considered, so that the MIMO channel resources cannot be fully utilized, and the utilization rate of the system resources is low. When MU-MIMO is carried out, if the size difference of data packets needing to be transmitted is large, the RBG allocation has a lot of unutilized resources. As shown in fig. 2, when the UE1 is paired with the UE2 and the UE3 is paired with the UE4, since the resource required by the UE1 is much larger than the resource required by the UE2, the resource allocated to the UE2 is idle and cannot be fully utilized in the process from completion of data transmission of the UE2 to non-completion of the UE 1.

In order to solve the above problems in the prior art, an embodiment of the present invention provides a resource scheduling method, which is applied to a communication system as shown in fig. 3, where as shown in fig. 3, the communication system 10 includes a base station apparatus 11 and a plurality of UEs 12. The base station apparatus 11 is connected to the plurality of UEs 12 in a wireless manner.

The base station apparatus 11 includes a plurality of TR antenna arrays, which are composed of a receiving antenna array (RX array) and a transmitting antenna array (TX array), and are used for signal transmission with the plurality of UEs 12 and carrying data transmitted with the plurality of UEs 12.

The base station apparatus 11 may be configured to send a channel state information-reference signal (CSI-RS) to the UE12 within an active partial Bandwidth (BWP) so that the UE12 may estimate a channel after receiving the CSI-RS and report channel quality information back to the base station apparatus 11.

The channel quality information includes a Channel Quality Indicator (CQI), a Precoding Matrix Indicator (PMI), a Rank Indicator (RI), and the like.

Base station device 11 may also be configured to receive SRS transmitted by UE12 within active BWP. The base station apparatus 11 may be further configured to process the received SRS sent by the UE12 to obtain a signal to interference plus noise ratio (SINR), an RSRP, a Precoding Matrix Indication (PMI), and the like of a channel between the base station apparatus 11 and the UE 12.

The base station apparatus 11 may further be configured to count the number of transmitted data packets and the data amount of the data packets of the UE12 to determine a large traffic UE and a small traffic UE among the UEs 12.

Base station apparatus 11 may also be configured to pair candidate paired UEs of plurality of UEs 12 for MU-MIMO.

The base station device 11 may be further configured to perform scheduling transmission of user data according to a pairing result after pairing the candidate paired UEs. The method comprises the following steps that MU-MIMO pairing scheduling is carried out among large-flow business UE, and layered spatial multiplexing is carried out; and MU-MIMO pairing is carried out between the small flow business UEs, and layered spatial multiplexing is carried out.

Fig. 4 is a flow diagram illustrating a method of communication, according to some example embodiments. In some embodiments, the above-described resource scheduling method may be applied to the base station apparatus 11 in the communication system as shown in fig. 3. The following describes a resource scheduling method provided in an embodiment of the present invention with reference to the accompanying drawings.

As shown in fig. 4, the resource scheduling method provided in the embodiment of the present invention is applied to the communication system 10, and includes S201 to S204.

S201, the base station equipment obtains the service flow characteristics of each candidate paired UE in a plurality of candidate paired UEs initiating data transmission requests.

Wherein each traffic flow characteristic includes the number of the plurality of data packets transmitted in the last transmission period and the data amount of each data packet.

As a possible implementation, the base station device determines identities of a plurality of candidate paired UEs that initiate a data transmission request. Further, the base station device determines, from the historical transmission record according to the UE identifier and the preset duration of the transmission period, the transmission record of the UE in the previous transmission period, and determines, from the transmission record of the UE, the number of data packets transmitted by the UE in the uplink (or downlink) and the data volume of each data packet.

It should be noted that the duration of the transmission period may be set in advance in the base station device by the operation and maintenance personnel of the base station. The shorter the duration of the transmission cycle is set, the faster the base station device identifies the number of data packets transmitted by the UE and the data amount of each data packet, but the accuracy of the identification may be reduced.

For example, the preset transmission cycle duration may be set to 3 seconds. If the candidate paired UEs determined by the base station device include UE1, UE2, UE3, and UE4, the number of data packets (e.g., the number of data packets may be 220, 340, 360, and 278) and the data amount of each data packet (e.g., the data amount may be 700B, 600B, 900B, and 120B) corresponding to UE1, UE2, UE3, and UE4 in 3 seconds of the last transmission cycle are respectively queried from the historical transmission records.

S202, the base station equipment judges whether a plurality of first paired UE exist in the candidate paired UE according to the service characteristic flow of each candidate paired UE.

The number of the plurality of data packets transmitted by each first paired UE in the last transmission period is greater than or equal to a first threshold, and a first ratio of each first paired UE in the last transmission period is greater than or equal to a second threshold. The first proportion is the proportion of a first data packet in the plurality of data packets, and the data volume of the first data packet is larger than a third threshold value.

As a possible implementation manner, the base station device determines, based on the traffic flow characteristic of each candidate paired UE determined in step S201, a data amount of each data packet in a plurality of data packets transmitted by each candidate paired UE, determines a data packet of which the data amount is greater than a third threshold value in the plurality of data packets as a first data packet, determines the number of the first data packet, and further determines, according to the number of the first data packet and the number of the plurality of data packets, a proportion of the first data packet in the plurality of data packets. Further, the base station device determines, as the first paired UE, the candidate paired UE in which the number of the plurality of data packets is greater than or equal to a first threshold and the first occupancy is greater than or equal to a second threshold in transmission of each candidate paired UE.

It should be noted that the first threshold, the second threshold, and the third threshold mentioned above may be set in advance in the base station device by an operation and maintenance person of the base station device. The number of the determined first paired UEs may be controlled by the size of the first threshold, the second threshold, and the third threshold, and the larger the set numerical values of the first threshold, the second threshold, and the third threshold are, the smaller the number of the determined first paired UEs is.

For example, if the number of candidate paired UEs is N, the base station device determines that the number of multiple data packets transmitted to the ith candidate paired UE in the last transmission period T is S _i The number of the first packets is Sb _i . The first proportion R of the first data packet of the ith candidate paired UE _i As shown in the following equation:

wherein, for the ith candidate paired UE, if S _i Greater than or equal to a first threshold, and R _i If the second threshold value is larger than or equal to the first threshold value, the ith candidate paired UE is determined to be the first paired UE. Further, the base station device determines whether other UEs in the N candidate paired UEs are the first paired UEs in the same manner.

In the above example, the first threshold may be set to 200, and the second threshold may be set to 90%. If the UE6 transmitted the number S of the plurality of data packets in the last transmission cycle _UE6 Number of first packets Sb of 210 _UE6 Is 195, then R is determined _UE6 92.86% greater than the second threshold value 90%, and S _UE6 Above the first threshold 200, the UE6 is determined to be the first paired UE.

In some embodiments, after determining a plurality of first paired UEs, the base station device combines all the first paired UEs into a first set, where candidate paired UEs included in the first set are all large-traffic service UEs, so that when the base station device performs pairing scheduling resources on the candidate paired UEs in a subsequent process, the base station device selects UEs from the set for pairing, and can avoid that the large-traffic service UEs are affected by small-traffic service UEs.

For example, if the determined first paired UEs are UE1, UE3, UE4, UE6, UE9, and UE13, respectively, the first set a is { UE1, UE3, UE4, UE6, UE9, UE13 }.

S203, the base station apparatus determines a plurality of first target paired UEs from the plurality of first paired UEs when the plurality of first paired UEs exist in the plurality of candidate paired UEs.

The plurality of first target paired UEs are UEs performing spatial hierarchical multiplexing in a paired manner, and the number of spatial hierarchical multiplexing layers occupied by the plurality of first target paired UEs is less than or equal to the maximum number of spatial hierarchical multiplexing layers supported by the base station device.

As a possible implementation manner, the base station device determines a plurality of first target paired UEs from the plurality of first paired UEs determined in step S202 according to the number of multiplexing layers of spatial hierarchies supported by the base station device and the number of multiplexing layers of spatial hierarchies required to be occupied by each first paired UE.

For example, if the number of multiplexing layers of the spatial hierarchy supported by the base station device is 16, the first paired UEs are UE1, UE2, UE3, UE4, UE5, UE6, UE7, and UE8, and the number of multiplexing layers of the spatial hierarchy required to be occupied by each first paired UE is 4, 2, 4, 3, 2, 4, and 4. Then, the base station device determines, from the UE1-UE8, that the first target paired UE may select the first target paired UE according to the sequence stored by the UE identifier, and further determines that the first target paired UE in two slots (slots) is obtained, as shown in fig. 5, the first target paired UE in slot1 is UE1, UE2, UE3, UE4, and UE5, and the first target paired UE in slot2 is UE6, UE7, and UE 8.

Optionally, the base station device may select the first target paired UE from the UEs 1-UE8, and further sequentially select the first target paired UEs according to the order of the multiplexing layers of the spatial hierarchy required to be occupied by the UEs from large to small, so as to determine the first target paired UEs in two slots, as shown in fig. 6, the first target paired UEs in slot1 are UE1, UE3, UE6, and UE7, and the first target paired UEs in slot2 are UE2, UE4, UE5, and UE 8.

And S204, the base station equipment allocates the same resource block group for the first target paired UEs.

As a possible implementation manner, the base station device allocates the same resource block group to the multiple first target paired UEs in the same slot based on the pairing result, so that the multiple first target paired UEs perform transmission of system messages or user data.

In some embodiments, a scheduler in the base station apparatus allocates resources on a Physical Downlink Shared Channel (PDSCH) to multiple first target-paired UEs in the same slot, and selects an appropriate Modulation and Coding Scheme (MCS) for transmission of system messages or user data. Wherein, include: allocating time-frequency domain resources on a PDSCH for the first target pairing UE; allocating demodulation reference signal (DMRS) resources to the first target paired UE, so that the first target paired UE demodulates the PDSCH; a suitable MCS is selected for the first target pair UE for transmission of data on PDSCH.

It should be noted that, in the third generation partnership project (3rd 3GPP) TS 38.214 V15.4.0, the section 5.1.2.2 Resource allocation in frequency domain specifies two Resource allocation manners, type0 and type1, type0 is an allocation manner of RBG granularity allocation, and supports discontinuous allocation and continuous allocation; type1 is an allocation scheme that supports only continuous allocations in Resource Block (RB) granularity allocations. When allocating PDSCH frequency domain resources to the first target paired UE, the resource may be allocated to the first target paired UE with reference to the content in the above specification.

In a design, in order to avoid that when the UE performs data transmission after pairing, the transmission efficiency of the UE performing pairing is affected by the UE with poor channel quality, as shown in fig. 7, before the base station device obtains the service traffic characteristics of each candidate paired user of the multiple candidate paired users initiating the data request, the resource scheduling method provided in the embodiment of the present invention further includes S301-S302.

S301, the base station equipment acquires the target parameters.

Wherein the target parameter comprises SINR and/or CQI. The target parameter is used to indicate the channel quality of the channel between the base station device and the UE that initiated the data transmission request.

As a possible implementation manner, if the target parameter is SINR, the base station device receives an SRS sent by a UE initiating a data transfer request, and acquires SINR of a channel between the base station device and the UE.

As another possible implementation manner, if the target parameter is CQI, the base station device sends CSI-RS to the UE that initiates the data transmission request, and the UE performs corresponding processing after receiving the CSI-RS, and reports CQI of a channel between the base station device and the UE.

S302, the base station device determines that the UE initiating the data transmission request is the candidate pairing UE under the condition that the target parameter is greater than or equal to the fourth threshold value.

As a possible implementation manner, in the case that the target parameter is SINR, the fourth threshold is SINR _Threshold If the base station equipment determines that the SINR of the UE initiating the data transmission request is greater than or equal to the SINR _Threshold Then the UE is determined to be a candidate paired UE.

Illustratively, if the base station apparatus determines the SINR in step S301 above _UE1 ＝26、SINR _UE2 ＝22、SINR _UE3 ＝25、SINR _UE4 18 and SINR _UE5 29 and SINR _Threshold 25, the base station device determines UE1, UE3, and UE5 as candidate paired UEs by comparing the SINR value of each UE initiating the data transmission request with a fourth threshold.

It should be noted that the fourth threshold may be set in the base station device in advance by an operation and maintenance person of the base station device. The higher the fourth threshold is set, the better the channel quality of the channel between the screened UE and the base station device is, and the lower the fourth threshold is set, the more candidate paired UEs are screened.

As another possible implementation, in the case that the target parameter is CQIThe fourth threshold is CQI _Threshold If the base station equipment determines that the CQI of the UE initiating the data transmission request is greater than or equal to the CQI _Threshold Then the UE is determined to be a candidate paired UE.

Illustratively, if the base station apparatus determines the CQI in step S301 _UE1 ＝15、CQI _UE2 ＝19、CQI _UE3 ＝23、CQI _UE4 22 and CQI _UE5 20, and CQI _Threshold The base station apparatus determines the UE3, the UE4, and the UE5 as candidate paired UEs by comparing the CQI value of each UE initiating the data transmission request with a fourth threshold value, 20.

As another possible implementation manner, in the case that the target parameters are SINR and CQI, the fourth threshold values are SINR respectively _Threshold And CQI _Threshold If the base station equipment determines that the SINR of the UE initiating the data transmission request is greater than or equal to the SINR _Threshold And the CQI of the UE is greater than or equal to the CQI _Threshold Then the UE is determined to be a candidate paired UE.

Illustratively, if the base station apparatus determines the SINR in step S301 above _UE1 ＝26、SINR _UE2 ＝22、SINR _UE3 ＝25、SINR _UE4 18 and SINR _UE5 ＝29；CQI _UE1 ＝15、CQI _UE2 ＝19、CQI _UE3 ＝23、CQI _UE4 22 and CQI _UEs 20. And, SINR _Threshold ＝25，CQI _Threshold The base station device compares the SINR value and the CQI value of each UE initiating the data transmission request with a fourth threshold value, respectively, and determines that the UE3 and the UE5 are candidate paired UEs.

It can be understood that, in the resource scheduling method provided in the embodiment of the present invention, before the UE initiating the data transmission request is paired, the UE is screened according to the channel quality, so that the channel quality of the UE participating in the pairing is ensured to be good, the UE with poor channel quality is prevented from affecting the transmission of other UEs, and the transmission efficiency is reduced.

In one design, to avoid interference caused by other paired UEs when the first target paired UE performs data transmission, as shown in fig. 8, the resource scheduling method provided in the embodiment of the present invention further includes S401 to S403.

S401, the base station equipment determines a spatial interference tolerance between the second paired UE and the third paired UE.

The second paired UE is any one of the plurality of first paired UEs, and the third paired UE is a UE of the plurality of first paired UEs except the second paired UE.

It should be noted that the spatial interference tolerance between the paired UEs refers to a spatial interference difference between the paired UEs, and the larger the spatial interference tolerance is, the smaller the interference of the paired users during spatial layered multiplexing is, and the better the performance of the paired MU-MIMO is.

As a possible implementation manner, the base station device arbitrarily selects one UE from the first paired UEs to determine as the second paired UE, and arbitrarily selects one UE from the first paired UEs except the second paired UE to determine as the third paired UE, and calculates a spatial interference tolerance between the second paired UE and the third paired UE.
