Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. 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 application, the meaning of "a plurality" means two or more unless otherwise specified.
The channel multiplexing method provided by the embodiment of the present application is applied to the channel multiplexing system 100 shown in fig. 1; the channel multiplexing system comprises a base station 101, a first terminal 102 and at least one second terminal 103.
The base station 101, the first terminal 102 and the second terminal 103 perform traffic transmission via wireless channels. The service transmitted between the base station 101 and the first terminal 102 is a first service; the service transmitted between the base station 101 and the second terminal 103 is a second service; the first service has a higher priority than the second service.
The embodiment of the present application provides a channel multiplexing method, which may be executed by a base station 101, and the following description takes the base station as a 5G base station, a first service as a URLLC service, and a second service as an eMBB service as an example.
As shown in fig. 2, the method includes S201-S204:
s201, when the appointed channel resource is idle, the base station transmits at least one second service by using the appointed channel resource.
The appointed channel resource is a channel resource configured for a first service in advance; the first service has a higher priority than the second service.
Illustratively, URLLC traffic typically requires a one-way 0.5ms delay and 99.999% reliability, thus setting the priority of URLLC traffic to high priority traffic. The eMB service has lower requirements on time delay and reliability, so the eMB service is set as a low-priority service. In order to ensure the time delay and reliability of the URLLC service, the 5G base station allocates the assigned channel resources for the URLLC service in advance, and if there are fewer URLLC services in the network, the assigned channel resources allocated for the URLLC service will be idle, resulting in the waste of the assigned channel resources and reducing the network performance. Therefore, in order to make full use of the designated channel resources, when the designated channel resources are not used for transmitting the URLLC traffic, the eMBB traffic is transmitted using the designated channel resources.
Illustratively, the designated channel resources are time-frequency resources.
S202, if the base station receives the indication of transmitting the first service in the process of transmitting the second service by using the appointed channel resource, acquiring a signal-to-noise ratio (SNR) value of the first terminal and at least one SNR value of the second terminal.
The first terminal is a terminal for transmitting the first service, and the second terminal is a terminal for transmitting the second service.
Specifically, if the base station receives an instruction to transmit the first service in the process of transmitting the second service by using the designated channel resource, the base station determines a resource block (described as a first resource block in the embodiment of the present application) that the first service needs to occupy, a second service that occupies the first resource block, and an SNR value of a second terminal corresponding to the second service that occupies the first resource block. And the base station acquires the SNR value of a second terminal corresponding to the second service occupying the first resource block, and stores the SNR value of the second terminal in a preset format. The first resource block is a resource block required to be occupied by the first service; at least one of the resource blocks constitutes the channel resource. The base station may periodically obtain and store the SNR value of the first terminal. When the base station needs to calculate the difference between the SNR value of the first terminal and the SNR value of the second terminal, the SNR value stored by the base station itself can be directly obtained.
Illustratively, as shown in fig. 3, the 5G base station assigns channel resources for URLLC traffic configuration in advance. The designated channel resources include three channel resource blocks: resource block 1, resource block 2, and resource block 3. The eMBB traffic may be transmitted in resource block 1, resource block 2, and resource block 3. When the eMB service is transmitted in the resource block 2 after the transmission of the eMB service in the resource block 1 is completed, the 5G base station receives the indication of transmitting the URLLC service, the eMB service will affect the transmission of the URLLC service, and at the moment, the 5G base station needs to judge according to the eMB service information and the URLLC service information.
In one implementation manner of this step, the method for the 5G base station to obtain the SNR value of the second terminal includes:
the 5G base station instructs a second terminal to transmit a channel Sounding Reference Signal (SRS) to measure an SNR value of the second terminal.
The 5G base station collects the SNR value of the second terminal before storing it in table 1:
| SNR | resource block 1 | Resource block 2 | Resource block 3 | … |
| eMBBUE1 | ||||
| eMBBUE2 | ||||
| eMBBUE3 | ||||
| … |
TABLE 1
The number of rows in table 1 is related to the number of second terminals corresponding to the second service currently being transmitted in the designated channel resource. The number of columns in table 1 is related to the number of hybrid automatic repeat request (HARQ) queues for the eMBB traffic, the scheduling granularity for the eMBB traffic, and the configuration density of resource blocks, where one HARQ queue is allocated for each scheduling granularity for the eMBB traffic.
Illustratively, if the number of the second terminals corresponding to the second service currently being transmitted in the specified channel resource is 20, the number of rows in table one is 21.
If the number of the eMBB service HARQ queues is N, the scheduling granularity is also N, and N resource blocks are configured in each HARQ queue, so that the total number of the resource blocks is N x N; the number of columns in table 1 is N × N + 1.
In an implementation manner of this step, the HARQ queue may be reallocated after the second terminal completes one service transmission, and the SNR value of the second terminal corresponding to each resource block needs to be re-measured after the HARQ queue is reallocated.
S203, determining a priority scheduling indication according to the SNR value of the first terminal and the SNR value of at least one second terminal.
Specifically, the SNR value of the first terminal pre-stored in the base station is obtained.
If the SNR value of the first terminal is obtained, obtaining the SNR value of at least one second terminal; calculating at least one first difference value according to the SNR value of the first terminal and the SNR value of at least one second terminal; the first difference is a difference between the SNR value of the first terminal and the SNR value of the second terminal.
And if the target first difference value is smaller than the first threshold value, determining a priority scheduling indication, wherein the priority scheduling indication is used for indicating to interrupt the transmission of the second service of the second terminal corresponding to the target first difference value.
If the target first difference value is not smaller than the first threshold, it indicates that the influence of the current SNR value of the second terminal on the first terminal is small, and the delay and reliability of the first service sent by the first terminal are not influenced, and at this time, the priority scheduling indication does not need to be sent to the second terminal.
And if the SNR value of the first terminal is not obtained, judging whether the SNR value of each second terminal is greater than a second threshold value. And if the SNR value of the target second terminal is greater than or equal to the second threshold value, determining a priority scheduling indication, wherein the priority scheduling indication is used for indicating to interrupt the transmission of the second service of the target second terminal. If the SNR value of the target second terminal is not greater than or equal to the second threshold, the influence of the SNR value of the current second terminal on the first terminal is also shown to be small, and the time delay and the reliability of the first service sent by the first terminal cannot be influenced; there is no need to send the priority scheduling indication to the second terminal at this time.
Illustratively, the first threshold is 10db and the second threshold is-10 db.
In an implementation manner of this step, if the second service does not affect service transmission of the first service, the first service and the second service may be transmitted in the designated channel resource at the same time; and after receiving the second service, the 5G base station sends a retransmission instruction to a second terminal transmitting the second service if the second service cannot be decoded correctly.
S204, sending the priority scheduling indication to the second terminal so that the second terminal can execute the priority scheduling indication.
Specifically, the base station sends the priority scheduling indication to the second terminal through a control channel; the control channel comprises a dedicated control channel and a common control channel; the dedicated control channel is a channel allocated to each UE in the control channels, and the common control channel is a channel shared by all terminals in the control channels.
And if the first quantity meets a first preset condition, sending the priority scheduling indication to the second terminal through a dedicated control channel of the second terminal. Determining at least one bandwidth portion BWP in the designated channel resource if the first amount does not satisfy the first preset condition; the BWP is used for transmitting the second service; the BWP includes a dedicated control channel and a common control channel. And if the second quantity in the BWP meets a second preset condition, sending the priority scheduling indication to the second terminal through a dedicated control channel of the second terminal in the BWP. And if the second quantity in the BWP meets a third preset condition, sending the priority scheduling indication to the second terminal through a common control channel in the BWP. Wherein the first number is the number that the first difference is smaller than a first threshold or the number that the SNR value of the second terminal is greater than a second threshold; the first difference is a difference between the SNR value of the first terminal and the SNR value of the second terminal. The second number is a number that the first difference is smaller than a first threshold value or a number that an SNR value of the second terminal is larger than a second threshold value within the BWP.
Illustratively, the first preset condition is that the first number is equal to 1, the second preset condition is that the second number is equal to 1, and the third preset condition is that the second number is greater than 1.
In an implementation manner of this step, since the URLLC service has low delay and high reliability, and the URLLC service occupies more frequency domain resources, the URLLC service may conflict with multiple eMBB services in the frequency domain. As shown in fig. 3, the URLLC service collides with two eMBB services in the frequency domain, namely eMBB UE1 and eMBB UE 2; if the SNR values of the eMBB UE1 and the eMBB UE2 both affect URLLC traffic, the 5G base station needs to send priority scheduling indications to the eMBB UE1 and the eMBB UE2, respectively.
The 5G base station firstly determines that the number of the terminals needing to send the priority scheduling indication is more than 1, and the priority scheduling indication cannot be sent through a special control channel. The 5G base station then determines whether the eMBB UE1 and the eMBB UE2 belong to the same BWP.
If the eMB UE1 and the eMB UE2 belong to the same BWP, the 5G base station judges that the priority scheduling indication cannot be sent through a dedicated control channel. In order to save control channel resources, the 5G base station combines the priority scheduling indications that need to be sent to the eMBB UE1 and eMBB UE2 into one priority scheduling indication and sends the priority scheduling indication to the eMBB UE1 and eMBB UE2 through a common control channel. The eBB UE1 and the eBB UE2, after receiving the priority scheduling indication, identify a priority scheduling indication related to themselves and perform corresponding actions.
If the eMB UE1 and the eMB UE2 do not belong to the same BWP, the 5G base station sends the priority scheduling indication to the eMB UE1 and the eMB UE2 through dedicated control channels corresponding to the eMB UE1 and the eMB UE2, respectively.
According to the channel multiplexing method and device, when the designated channel resource is idle, the designated channel resource is utilized to transmit at least one second service; if receiving an instruction of transmitting the first service in the process of transmitting the second service by using the appointed channel resource, acquiring a signal-to-noise ratio (SNR) value of a first terminal and an SNR value of at least one second terminal; determining a priority scheduling indication according to the SNR value of the first terminal and the SNR value of at least one second terminal; and sending the priority scheduling indication to the second terminal so that the second terminal can execute the priority scheduling indication. According to the method and the device, the second service is transmitted when the designated channel resource is idle, when the designated channel resource needs to transmit the first service, the priority scheduling indication is determined according to the SNR value of the first terminal and the SNR value of the second terminal, whether the transmission of the low-priority service is interrupted or not is judged, the second service can be transmitted under the condition that the transmission of the first service is not influenced, and the utilization rate of the channel resource is improved.
