Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
The invention provides a method for configuring control channel unit resources, aiming at the problem of low utilization efficiency of uplink/downlink CCE resources caused by the adoption of fixed uplink/downlink CCE proportion allocation in the existing subframe, and the resource utilization efficiency is improved by adjusting the configuration of the uplink/downlink CCE resources in the subframe according to the actual requirement in transmission.
As shown in fig. 1, a method for configuring control channel element resources according to an embodiment of the present invention includes:
step 101, determining first configuration information of a first subframe and a second subframe corresponding to a CCE resource of a user control channel element according to a scheduling user set; the first subframe is a subframe for sending uplink/downlink control information, and the second subframe is a special subframe for sending downlink control information;
step 102, adjusting the configuration of the CCE resources in the first subframe according to the first configuration information and the actual occupation information of the CCE resources in transmission to obtain second configuration information;
and 103, configuring the second configuration information to the terminal.
The method for configuring the control channel element resource of the embodiment of the present invention is applied to a network side device, and through steps 101 to 103, the network side device first knows first configuration information of CCE resources corresponding to a first subframe and a second subframe according to a scheduling user set, where the first subframe is a subframe (e.g. 3, 8 subframes) for sending uplink/downlink control information, and the second subframe is a dedicated subframe (e.g. non-3, 8 subframes) for sending downlink control information; then, the configuration of the CCE resources in the first subframe is adjusted by combining the first configuration information and the actual occupation information of the CCE resources in transmission to obtain second configuration information; and finally, configuring the second configuration information to a terminal, namely user equipment. Therefore, after the scheduling user set determines the first configuration information of the subframe for sending the uplink/downlink control information and the special subframe for sending the downlink control information, the CCE resource configuration in the first subframe is adjusted by combining the actual occupation information of the CCE resource in transmission, so that the resource utilization efficiency of a high-load scene is effectively improved in actual use, the spectrum efficiency is improved, and the user requirements are met.
It should be noted that the scheduled user set is determined by a network side device (e.g., a base station) calculating user priorities according to a PF (Proportional Fair) algorithm.
In the embodiment of the invention, in order to solve the uplink/downlink requirements of the user on the CCE resources, the actual occupation information of the CCE resources in transmission can be obtained through real-time monitoring. As shown in fig. 2, step 102 includes:
step 1021, acquiring an uplink CCE resource proportion, a first downlink CCE resource proportion and a second downlink CCE resource proportion within a preset time period in the actual occupation information; wherein the first downlink CCE resource occupation ratio corresponds to the first subframe, and the second downlink CCE resource occupation ratio corresponds to the second subframe;
step 1022, adjusting the configuration of CCE resources in the first subframe according to the first configuration information, the uplink CCE resource proportion, the first downlink CCE resource proportion, and the second downlink CCE resource proportion, to obtain second configuration information.
Here, in order to solve the actual requirement and perform subsequent processing, it is preferable that the uplink CCE resource ratio and the downlink CCE resource ratio within a preset time length in the actual occupation information be acquired based on the monitored history information. Therefore, the adjustment of the configuration of the CCE resources in the first subframe is determined according to the first configuration information, the uplink CCE resource occupation ratio, the first downlink CCE resource occupation ratio and the second and downlink CCE resource occupation ratios, and the second configuration information is obtained.
Specifically, the step 1022 includes:
counting the number of occupied uplink CCE resources, the number of occupied first downlink CCE resources, the number of occupied second downlink CCE resources, the allocable number of uplink CCE resources, the allocable number of first downlink CCE resources and the allocable number of second downlink CCE resources within the preset time length;

Therefore, in further detail, as shown in fig. 3, step 1022 includes:
step 10221, comparing the uplink CCE resource allocation adjustment ratio with the uplink CCE resource allocation adjustment ratio to obtain a first comparison result, where the uplink CCE resource allocation adjustment ratio is α × ULCCE；

Step 10223, comparing the second downlink CCE resource allocation adjustment duty ratio with a second downlink CCE resource allocation adjustment duty ratio to obtain a third comparison result, wherein the second downlink CCE resource allocation adjustment duty ratio is γ DL'CCE；
Step 10224, adjusting the configuration of CCE resources in the first subframe according to the first comparison result, the second comparison result, and the third comparison result, to obtain second configuration information.
In the above, the first configuration information includes contents of CCE resource allocation ratios not only for different subframes, for example, an uplink CCE resource allocation ratio ULCCEFirst downlink CCE resource allocation ratio DLCCEAnd the second downlink CCE resource allocation accounts for DL'CCEAnd moreover, corresponding adjustment factors are set based on the actual working state of the network side equipment, and the maximum value of CCE resources which can be used for bearing uplink control information and/or downlink control information on each subframe is limited. Of course, the adjustment factor is a dynamic adjustable parameter, and can be adjusted by a system or an operator according to the real-time working state of the network device. Thus, as described above, when comparing the actual occupancy to the available upper limit, and correspondingly, P will be comparedULAnd α ULCCEAs a first comparison result, compare PDLAnd beta DLCCEIs compared with P 'as a second comparison result'DLAnd γ'CCEThe size relationship of the CCE resource is used as a third comparison result, and finally whether the current use of the CCE resource is limited is grasped more clearly by the three comparison results, so that the adaptive adjustment is carried out, and the CCE resource in the first subframe is reconfigured.
Wherein, step 10224 comprises:
if the uplink CCE resource occupation ratio is greater than the uplink CCE resource allocation adjustment occupation ratio, the uplink CCE resource occupation ratio is less than 1, and the first downlink CCE resource occupation ratio is less than the first downlink CCE resource allocation adjustment occupation ratio, increasing the number of the allocable uplink CCE resources in the first subframe according to a first preset step length, and decreasing the number of the allocable downlink CCE resources in the first subframe according to the first preset step length to obtain second configuration information.
Here, P is known from the respective comparison results obtained in the previous stepUL>α*ULCCE，PUL<1, and PDL<β*DLCCETherefore, it can be known that the uplink CCE resource of the first subframe is limited, the CCE resource originally allocated to the first subframe for carrying the uplink control information is not sufficient to complete the actual task of carrying the uplink control information, but the downlink CCE resource of the first subframe is idle. At this time, the number of the allocable uplink CCE resources in the first subframe is increased according to a first preset step size, and correspondingly, the number of the allocable downlink CCE resources in the first subframe is also decreased according to the first preset step size, and the idle downlink CCE resources are used for carrying uplink control information. Thus, the obtained second configuration information can effectively improve the resource utilization rate of the CCE resources under the high load. If the uplink is still limited after one adjustment, processing is continued according to the first preset step length, which is not described herein again.
Further, step 10224 includes:
if the uplink CCE resource occupation ratio is greater than the uplink CCE resource allocation adjustment occupation ratio, the uplink CCE resource occupation ratio is less than 1, the first downlink CCE resource occupation ratio is greater than the first downlink CCE resource allocation adjustment occupation ratio, and the second downlink CCE resource occupation ratio is less than the second downlink CCE resource allocation adjustment occupation ratio, increasing the number of the allocable uplink CCE resources in the first subframe according to a second preset step length, and decreasing the number of the allocable downlink CCE resources in the first subframe according to the second preset step length to obtain second configuration information.
Here, P is known from the respective comparison results obtained in the previous stepUL>α*ULCCE，PUL<1，PDL>β*DLCCEAnd P'DL<γ*DL’CCEKnowing that the uplink CCE resource of the first subframe is limited, C originally allocated on the first subframe for carrying uplink control information isThe CE resource is not enough to complete the actual uplink control information bearing task, the downlink CCE resource of the first subframe is already used for the downlink control information bearing task, but the downlink CCE resource of the second subframe is idle. At this time, considering that more downlink control information bearing tasks can be allocated to the second subframe, the number of allocable uplink CCE resources in the first subframe can be increased according to the second preset step size, and correspondingly, the number of allocable downlink CCE resources in the first subframe is also decreased according to the second preset step size, so as to meet the actual uplink control information bearing task requirement. Thus, the obtained second configuration information can effectively improve the resource utilization rate of the CCE resources under the high load. If the uplink is still limited after one adjustment, processing is continued according to a second preset step length, which is not described herein again.
Further, since there is a possibility that the downlink CCE resource is limited even when the amount of information of the downlink control information is large, step 10224 includes:
if the uplink CCE resource occupation ratio is smaller than the uplink CCE resource allocation adjustment occupation ratio and the first downlink CCE resource occupation ratio is larger than the first downlink CCE resource allocation adjustment occupation ratio, increasing the number of the downlink CCE resources which can be allocated in the first subframe according to a third preset step length, and decreasing the number of the uplink CCE resources which can be allocated in the first subframe according to the third preset step length to obtain second configuration information.
Here, P is known from the respective comparison results obtained in the previous stepUL<α*ULCCEAnd P isDL>β*DLCCEIt is known that, for the first subframe, the downlink CCE resource thereof is already limited, the CCE resource allocated to the first subframe for carrying the downlink control information is not sufficient to complete the actual task of carrying the downlink control information, but the uplink CCE resource thereof is not limited, the CCE resource allocated to the first subframe for carrying the uplink control information is sufficient to complete the actual task of carrying the corresponding uplink control information, and the current uplink CCE resource is idle. Then, at this time, the downlink CCE resources in the first subframe are increased according to a preset third preset step sizeThe allocable number correspondingly reduces the allocable number of the uplink CCE resources in the first subframe by the third preset step length, and the idle uplink CCE resources are used for bearing downlink control information, so that the resource utilization rate of the CCE resources under the high downlink load is effectively improved. Similarly, if the downlink is still limited after one adjustment, the processing is continued according to a third preset step length, which is not described herein again.
Thereafter, step 103 includes:
reconfiguring the uplink CCE resource and the downlink CCE resource in the first subframe according to the second configuration information;
and sending the uplink control information and the downlink control information to the terminal according to the reconfigured uplink CCE resource and downlink CCE resource.
Here, after the second configuration information is obtained again through the adjustment in the above steps, the uplink CCE resource and the downlink CCE resource in the first subframe are reconfigured based on the second configuration information, and the uplink control information and the downlink control information are transmitted to the terminal. The second configuration information obtained by adjustment and re-acquisition is completed by combining the capacity of the subframe and the actual requirement, so that the requirement of a user is fully met, and the effective delivery of the control information is ensured.

Therefore, after the scheduling user set determines the first configuration information of the subframe for sending the uplink/downlink control information and the special subframe for sending the downlink control information, the CCE resource configuration in the first subframe is adjusted by combining the actual occupation information of the CCE resource in transmission, so that the resource utilization efficiency of a high-load scene is effectively improved in actual use, the spectrum efficiency is improved, and the user requirements are met.
