Detailed Description
As can be seen from the above, the existing retransmission scheme may cause a long delay and poor performance of the communication system.
In the embodiment of the invention, when the received network configuration information comprises enabling information triggering communication link recommendation, a target communication link with communication quality meeting preset selection conditions is selected and recommended to the base station. The base station sends the updated scheduling information according to the target communication link, so that the user terminal can receive information on the communication link with better communication quality, and the performance of the communication system can be improved.
In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, embodiments accompanying figures are described in detail below.
An embodiment of the present invention provides a scheduling method, which is described in detail below with reference to fig. 1 through specific steps.
Step S101, receiving network configuration information.
In a specific implementation, the network configuration information is issued from the base station to the user equipment, and the network configuration information may include: triggering enabling information for recommending the communication link and a communication quality judgment threshold.
After receiving the network configuration information, the user terminal can obtain the enabling information triggering the communication link recommendation and the communication quality judgment threshold. After acquiring the enabling information, the user terminal may perform steps S102 to S103, that is, perform selection and reporting of the target communication link.
In the embodiment of the present invention, the communication quality decision threshold may include at least one of the following: a Reference Signal Received Power (RSRP) threshold, a Signal to Interference plus Noise Ratio (SINR) threshold, a Reference Signal Received Quality (RSRQ) threshold, an RSRP difference threshold, an SINR difference threshold, and an RSRQ difference threshold. That is, the communication quality decision threshold may be only one of an RSRP threshold, an SINR threshold, an RSRQ difference threshold, an RSRP difference threshold, an SINR difference threshold, and an RSRQ difference threshold, or may be any two or more of the above four thresholds.
In practical application, the specific content of the communication quality decision threshold may be determined according to practical application scenarios and requirements, which is not described in detail herein.
In a specific implementation, the network configuration information may be configured by the base station through a higher layer signaling, for example, the base station configures the network configuration information through a Radio Resource Control (RRC) signaling. The network configuration Information may also be configured by the base station through Downlink Control Information (DCI).
And step S102, selecting a target communication link with the communication quality meeting a preset condition according to the communication quality judgment threshold.
In specific implementation, a communication link with a communication quality meeting a preset selection condition may be selected according to the communication quality decision threshold. In the embodiment of the present invention, the preset selection condition may be: the communication quality parameter is better than the communication quality decision threshold in the network configuration information. In other words, the communication quality of the target communication link is better than the communication quality corresponding to the communication quality decision threshold in the network configuration information.
In the embodiment of the present invention, when the communication quality decision threshold includes an RSRP threshold, an RSRP value corresponding to each communication link may be compared with the RSRP threshold, and a communication link, which has an RSRP value greater than the RSRP threshold and is the maximum RSRP value, is selected as the target communication link. It is to be understood that multiple or all of the communication links corresponding to all RSRP values greater than the RSRP threshold may also be selected as the target communication links.
When the communication quality decision threshold includes the SINR threshold, the SINR value corresponding to each communication link may be compared with the SINR threshold, and the communication link having the SINR value greater than the SINR threshold and corresponding to the maximum SINR is selected as the target communication link. It is to be understood that, as the target communication link, multiple or all of the communication links corresponding to all SINR values greater than the SINR threshold may also be selected.
When the communication quality decision threshold includes an RSRQ threshold, the RSRQ value corresponding to each communication link may be compared with the RSRQ threshold, and a communication link whose RSRQ value is greater than the RSRQ threshold and is the maximum RSRQ is selected as the target communication link. It is to be understood that multiple or all of the communication links corresponding to all RSRQ values greater than the RSRQ threshold may also be selected as the target communication link.
For example, if the number of the communication links with RSRP values greater than the RSRP threshold is 5, 2 communication links with the maximum RSRP values are selected as the target communication links, or all the communication links with RSRP values greater than the RSRP threshold are all selected as the target communication links.
Correspondingly, if the number of the communication links corresponding to the SINR values greater than the SINR threshold is 4, then 2 communication links with the largest RSRP value are selected as target communication links, or all communication links corresponding to the SINR values greater than the SINR threshold are all selected as target communication links.
Correspondingly, if the number of the communication links corresponding to the RSRQ values greater than the RSRQ threshold is 4, 2 communication links with the maximum RSRP value are selected as target communication links, or all the communication links corresponding to the RSRQ values greater than the RSRQ threshold are all used as target communication links.
In the embodiment of the present invention, when the communication quality decision threshold includes an RSPR difference threshold, if an RSRP value corresponding to the ith communication link is greater than an RSRP value corresponding to the jth communication link, and a difference between the RSRP value and the RSRP value is greater than the RSRP difference threshold, the ith communication link may be used as a target communication link. I is more than or equal to 1 and less than or equal to N, j is more than or equal to 1 and less than or equal to N, and N is the total number of the communication links.
For example, if the difference between the RSRP value corresponding to communication link 1 and the RSRP value corresponding to communication link 2 is greater than the RSRP difference threshold, communication link 1 is taken as the target communication link.
It will be appreciated that in actual practice, there may be multiple target communication links. For example, if the difference between the RSRP value corresponding to communication link 3 and the RSRP value corresponding to communication link 2 is greater than the RSRP difference threshold, communication link 3 is also used as the target communication link. If the difference between the RSRP value corresponding to the communication link 5 and the RSRP value corresponding to the communication link 4 is greater than the RSRP difference threshold, the communication link 5 is also used as the target communication link.
In this embodiment of the present invention, when the communication quality decision threshold includes an SINR difference threshold, if an SINR value corresponding to the ith communication link is greater than an SINR value corresponding to the jth communication link, and a difference between the two is greater than the SINR difference threshold, the ith communication link may be used as the target communication link.
For example, if the difference between the SINR value corresponding to communication link 1 and the SINR value corresponding to communication link 2 is greater than the SINR difference threshold, communication link 1 is taken as the target communication link.
It will be appreciated that in actual practice, there may be multiple target communication links. For example, if the difference between the SINR value corresponding to the communication link 3 and the SINR value corresponding to the communication link 2 is greater than the SINR difference threshold, the communication link 3 is also used as the target communication link. If the difference between the SINR value corresponding to the communication link 5 and the SINR value corresponding to the communication link 4 is greater than the SINR difference threshold, the communication link 5 is also used as the target communication link.
In the embodiment of the present invention, when the communication quality decision threshold includes an RSRQ difference threshold, if an RSRQ value corresponding to an ith communication link is greater than an RSRQ value corresponding to a jth communication link, and a difference between the RSRQ value and the RSRQ value is greater than the RSRQ difference threshold, the ith communication link may be used as a target communication link.
For example, if the difference between the RSRQ value corresponding to communication link 1 and the RSRQ value corresponding to communication link 2 is greater than the RSRQ difference threshold, communication link 1 is taken as the target communication link.
It will be appreciated that in actual practice, there may be multiple target communication links. For example, if the difference between the RSRQ value corresponding to communication link 3 and the RSRQ value corresponding to communication link 2 is greater than the RSRQ difference threshold, communication link 3 is also used as the target communication link. In another example, if the difference between the RSRQ value corresponding to communication link 5 and the RSRQ value corresponding to communication link 4 is greater than the RSRQ difference threshold, then communication link 5 is also used as the target communication link.
In the embodiment of the present invention, when the communication quality decision threshold includes two or more of a plurality of RSRP thresholds, SINR thresholds, RSRQ thresholds, RSRP difference thresholds, SINR difference thresholds, and RSRQ difference thresholds, the communication quality parameters corresponding to the selected target link may all satisfy the communication quality decision threshold.
For example, if the communication quality thresholds include an RSRP threshold and an RSRP difference threshold, the RSRP value corresponding to each communication link is compared with the RSRP threshold, and the RSRP value corresponding to each communication link is subtracted from the minimum RSRP value corresponding to all communication links. And taking the communication link of which the RSRP value is greater than the RSRP threshold and the difference with the minimum RSRP value is greater than the RSRP difference threshold as a target communication link.
And step S103, reporting the recommendation information corresponding to the target communication link to the base station.
In a specific implementation, after the user terminal selects the target communication link, the user terminal may report the recommendation information corresponding to the target communication link to the base station.
In specific implementation, the user terminal may report the recommendation information corresponding to the target communication link through the uplink resource. In the embodiment of the present invention, the recommendation information corresponding to the target communication link may include identification information of the target communication link. The identification information of the target link may be a TCI state identification (TCI state index).
In a specific implementation, the recommendation information may further include a signal strength value corresponding to the target communication link, and the signal strength value corresponding to the target communication link may be represented by at least one of: the SINR value corresponding to the target communication link, the RSRP value corresponding to the target communication link and the RSRQ value corresponding to the target communication link. After receiving the recommendation information reported by the user terminal, the base station can acquire which item or items of item communication links are recommended by the user terminal and the signal strength value corresponding to the recommended target communication links.
For example, the communication link selected by the user terminal is communication link 1, and the SINR value corresponding to communication link 1 is x. The user terminal transmits recommendation information on the uplink resource, wherein the recommendation information comprises: the identification information is 1 and the corresponding SINR value is x. After receiving the uplink resource reported by the user terminal, the base station can know that the communication link selected by the user terminal is communication link 1, and the SINR value corresponding to the communication link 1 is x.
In a specific implementation, the Uplink resource may be a Physical Uplink Shared Channel (PUSCH) resource, or may also be a Physical Uplink Control Channel (PUCCH) resource. In practical application, according to an actual application scenario and application requirements, a PUCCH resource may be selected to report recommended information corresponding to a target communication link, or a PUSCH resource may be selected to report recommended information corresponding to the target communication link.
In the embodiment of the present invention, when the uplink resource of the target communication link is a PUCCH resource, the PUCCH may be a dedicated PUCCH resource, and the dedicated PUCCH resource is dedicated to reporting the recommendation information corresponding to the target communication link.
When the special PUCCH resource conflicts with the PUCCH resource carrying the HARQ-ACK/SR/CSI, the special PUCCH resource can be discarded, that is, the user terminal does not report the recommendation information corresponding to the target communication link at the moment.
When the special PUCCH resource conflicts with the PUCCH resource carrying the HARQ-ACK/SR/CSI, the information carried on the special PUCCH resource can also be multiplexed to the PUCCH resource carrying the HARQ-ACK/SR/CSI, that is, the PUCCH resource carrying the HARQ-ACK/SR/CSI also carries the information carried on the special PUCCH resource.
When the uplink resource of the transmission target communication link is a PUSCH resource, the recommendation information corresponding to the target communication link may be carried by the dedicated MAC CE, and the MAC CE is reported to the base station by the PUSCH resource.
In a specific implementation, after the user terminal reports the recommendation information corresponding to the target communication link to the base station, the base station may generate corresponding updated scheduling information according to the recommendation information corresponding to the target communication link and issue the updated scheduling information to the user terminal. The user terminal can receive corresponding information according to the updated scheduling information issued by the base station.
It is understood that, in practical applications, the base station may not generate the corresponding updated scheduling information after receiving the recommendation information corresponding to the target communication link. If the user terminal does not receive the updated scheduling information issued by the base station, the user terminal can receive corresponding information according to the current scheduling.
In specific implementation, the base station may schedule the user terminal to perform retransmission on the target communication link, thereby reducing system delay and improving system performance.
Therefore, when the received network configuration information comprises enabling information triggering communication link recommendation, a target communication link with communication quality meeting preset selection conditions is selected and recommended to the base station. The base station sends the updated scheduling information according to the target communication link, so that the user terminal can receive information on the communication link with better communication quality, the performance of the communication system can be improved, and the time delay is reduced.
The embodiment of the present invention further provides another scheduling method, which is described in detail below with reference to fig. 2 through specific steps.
Step S201, network configuration information is issued to the user terminal.
In a specific implementation, the network configuration information is issued from the base station to the user equipment, and the network configuration information may include: triggering enabling information for recommending the communication link and a communication quality judgment threshold.
The communication quality decision threshold may comprise at least one of: a Reference Signal Received Power (RSRP) threshold, a Signal to Interference plus Noise Ratio (SINR) threshold, an RSRQ threshold, an RSRP difference threshold, an RSRQ difference threshold, and an SINR difference threshold. That is, the communication quality decision threshold may be only one of an RSRP threshold, an SINR threshold, an RSRQ threshold, an RSRP difference threshold, an SINR difference threshold, and an RSRQ difference threshold, or may be any two or more of the above.
Step S202, the recommendation information reported by the user terminal is received.
In a specific implementation, the user terminal may select a communication link whose communication quality meets a preset selection condition according to a communication quality threshold in the network configuration information. In the embodiment of the present invention, the preset selection condition may be: the communication quality parameter is better than the communication quality decision threshold in the network configuration information. In other words, the communication quality of the target communication link is better than the communication quality corresponding to the communication quality decision threshold in the network configuration information.
After selecting the target communication link, the user terminal may report the recommendation information corresponding to the target communication link to the base station.
In a specific implementation, the specific processes and principles of step S201 to step S202 may refer to step S101 to step S103, which are not described herein again.
Step S203, generating updated scheduling information according to the recommendation information.
In a specific implementation, after the user terminal reports the recommendation information corresponding to the target communication link to the base station, the base station may generate corresponding updated scheduling information according to the recommendation information corresponding to the target communication link and issue the updated scheduling information to the user terminal. The user terminal can receive corresponding information according to the updated scheduling information issued by the base station.

In a specific implementation, the recommendation information may further include: and the signal strength value corresponding to the target communication link.
