Detailed ways

The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present disclosure.

Fig. 1 is a schematic flowchart showing a method for sending data on a direct link according to an embodiment of the present disclosure. The direct link data transmission method shown in the embodiments of the present disclosure may be applicable to user equipment, and the user equipment may communicate with other devices through a direct link based on 5G NR (New Radio), and other devices include The base station also includes other user equipment. The user equipment may be, for example, a mobile phone, a tablet computer, a wearable device, or other electronic equipment.

As shown in FIG. 1, the method for sending data on a direct link may include the following steps:

In step S1, the information of the first time-frequency resource used to send the data of the first service type is sent to the base station;

In an embodiment, the first time-frequency resource may be independently selected by the user equipment. For example, the base station may configure a resource pool for the user equipment in advance or in real time. The resource pool includes one or more time-frequency resources. The time-frequency resource may be independently selected by the user equipment from the resource pool.

In an embodiment, the first time-frequency resource may occupy one or more symbols in the time domain, and may also occupy one or more subframes, and the first time-frequency resource may occupy one or more symbols in the frequency domain. Sub-carriers (or sub-bandwidths).

In step S2, the configuration information sent by the base station is received, where the configuration information is used to instruct the user equipment to send the second service type data on the second time-frequency resource, the first time-frequency resource and the The second time-frequency resource is different;

In an embodiment, the information of the first time-frequency resource may include the time-domain position of the first time-frequency resource, such as a subframe occupied in the time domain, and may also include the frequency-domain position of the first time-frequency resource, for example, The subcarriers occupied in the frequency domain may also include the period of the first time-frequency resource.

According to the information of the first time-frequency resource and the BSR (Buffer Status Report) sent by the user equipment, the base station can determine the position of the user equipment in the time domain and frequency domain of the first time-frequency resource independently selected by the user equipment. In order to determine a second time-frequency resource that is different from the first time-frequency resource, the user equipment may carry information of the first time-frequency resource in the BSR when sending the BSR to the base station.

After determining the second time-frequency resource, the base station may generate configuration information according to the information of the second time-frequency resource, where the configuration information is used to instruct the user equipment to send the second service type data on the second time-frequency resource The first time-frequency resource and the second time-frequency resource are different, for example, the second time-frequency resource is different from the first time-frequency resource in the frequency domain and/or the time domain in at least one cycle.

In step S3, the first service type data is sent on the first time-frequency resource, and the second service type data is sent on the second time-frequency resource.

In an embodiment, the user equipment sends the information of the first time-frequency resource for sending the first service type data to the base station, so that the base station can determine the position of the first time-frequency resource in the time domain and the frequency domain, so that the base station can determine The second time-frequency resource that is different from the first time-frequency resource is then instructed by the configuration information to instruct the user equipment to send the second service type data on the second time-frequency resource, so that the user equipment can respectively send the second time-frequency resource on different time-frequency resources. The data of the first service type and the data of the second service type ensure that the data of the two service types can be sent smoothly, thereby ensuring the good communication effect of the user equipment.

For example, the first time-frequency resource occupies sub-bandwidth 13 in the frequency domain and sub-frame 3 in the time domain with a period of 10 milliseconds. Then the second time-frequency resource determined by the base station is sub-bandwidth 13 in at least one period, and subframe Time-frequency resources other than 3, so that the user equipment can send the first type of service data in subband 13, subframe 3 in at least one cycle, and send the second type of service data outside of subband 13, subframe 3.

Among them, the first service type and the second service type may not specifically refer to a certain service type, but are used to indicate two different service types. The difference between the two service types refers to one or more requirements of the two service types For example, the delay allowed by the first service type is lower than the delay allowed by the second service type. That is, the data of the first service type is more urgent to transmit than the data of the second service type. The first time-frequency resource is sent through the first time-frequency resource. Since the first time-frequency resource can be independently selected by the user equipment, the first time-frequency resource can be determined faster than the second time-frequency resource configured by the base station through configuration information Resources, so as to complete the transmission of the first service type data faster, which helps to ensure the delay requirements of the first service type.

According to the information of the first time-frequency resource and the BSR sent by the user equipment, the base station can determine that the user equipment independently selects the position of the first time-frequency resource in the time domain and the frequency domain in each cycle, so as to determine that it is different from the first time-frequency resource Second time-frequency resource.

In an embodiment, the first time-frequency resource may be periodic, so the second time-frequency resource configured by the base station for the user equipment is at least in the frequency domain and/or time in one of the cycles. Different in the domain, it can be ensured that the first time-frequency resource used by the user equipment to send the first service type data, and the second service type data is sent on the second time-frequency resource

Fig. 2 is a schematic flowchart of another method for sending data on a direct link according to an embodiment of the present disclosure. As shown in FIG. 2, the sending the information of the first time-frequency resource used to send the first service type data to the base station includes:

In step S11, a buffer status report is sent to the base station, where the buffer status report carries the information of the first time-frequency resource.

In one embodiment, since the base station configures the resource for sending data for the user equipment, it needs to learn the buffer status of the user equipment. Specifically, it can be learned according to the buffer status report sent by the user equipment, that is, to configure the second time-frequency resource. Configure according to the buffer status report. For example, you can configure how many subcarriers the second time-frequency resource occupies in the frequency domain and how many symbols it occupies in the time domain. On the other hand, you need to make the configured second time-frequency resource information based on the first time-frequency resource. The second time-frequency resource is different from the first time-frequency resource.

Therefore, in this embodiment, the information of the first time-frequency resource is carried by the buffer status report, and the user equipment does not need to separately send the information of the first time-frequency resource, so as to reduce the occupation of the uplink channel by the user equipment. Wherein, the information of the first time-frequency resource can be represented by one or more bits in the buffer status report.

Take 1 bit representing the information of the first time-frequency resource as an example. If the value of this bit is 0, it means that the time-frequency position of the first time-frequency resource is A, and that the period of the first time-frequency resource is T1. The value of this bit is 1, indicating that the time-frequency position of the first time-frequency resource is B, and that the period of the first time-frequency resource is T2.

Take multiple bits representing the information of the first time-frequency resource as an example, for example, multiple bits are 3 bits, the first bit can indicate the position of the first time-frequency resource in the time domain, and the second bit The bit may indicate the position of the first time-frequency resource in the frequency domain, and the third bit may indicate the period of the first time-frequency resource in the frequency domain. For example, the value of the first bit is 1, the value of the second bit is 1, and the value of the third bit is 1, indicating that the time domain position of the first time-frequency resource is X1, and the frequency domain position is Y1. The period is T1; for example, the value of the first bit is 0, the value of the second bit is 0, and the value of the third bit is 0, indicating that the time domain position of the first time-frequency resource is X2, and the frequency domain The position is Y2 and the period is T2.

Optionally, the configuration information includes priority information of the second service type data, and the method further includes:

In step S4, if the first time-frequency resource and the second time-frequency resource are the same, compare the priority of the first service type data with the priority of the second service type data;

In step S5, if the priority of the first service type data is higher than the priority of the second service type data, send the first service type data in the first time-frequency resource, if the first service type data Second, the priority of the service type data is higher than the priority of the first service type data, and the second service type data is sent on the first time-frequency resource.

In one embodiment, in some cases (for example, time-frequency resources other than the second time-frequency resource have been configured), after determining the first time-frequency resource, the base station will still configure the user equipment with the first time-frequency resource. The second time-frequency resource with the same frequency resource is used to send the second service type data. In this case, the priority information of the second service type data can be carried in the configuration information, and the user equipment can determine the first service type data by itself The priority information of the first service type data can be compared with the priority of the second service type data.

In one embodiment, when the priority of the first service type data is higher than the priority of the second service type data, the first service type data is sent in the first time-frequency resource, and the second service type data If the priority of the data is higher than the priority of the first service type, the second service type data is sent in the first time-frequency resource, that is, according to the priority of the first service type data and the priority of the second service type data As a result of the comparison, the user equipment can choose to send service type data with a higher priority on the first time-frequency resource, thereby ensuring that service type data with a higher priority can be sent preferentially, ensuring better communication effects.

Optionally, the comparing the priority of the first service type data with the priority of the second service type data includes:

In step S41, the data packet service quality indicator of the first service type data and the data packet service quality indicator of the second service type data are compared.

In one embodiment, the data of the first service type may be determined by comparing the data packet quality of service indicator (Package QoS Indicator, PQI) of the data of the first service type with the data packet quality of service indicator of the data of the second service type. The priority of the data or the priority of the second service type data is higher. For example, the priority of the service type data with a larger data packet service quality indicator is higher.

Specifically, when the first time-frequency resource and the second time-frequency resource are the same, for example, the data packet service quality indicator of the first service type data is 2, and the data packet service quality indicator of the second service type data is 3. Since 3 is greater than 2, it can be determined that the priority of the second service type data is higher than the priority of the first service type data, so that the second service type data can be sent on the first time-frequency resource.

Among them, the configuration information carrying the data packet quality of service indicator may be downlink control information, that is, Downlink Control Information, or DCI for short, for example, DCI-5 may be used.

As for the same business type data, the quality of service of different data packets can be different, and different data packets can correspond to different data packet quality of service indicators, so according to the data packet quality of service indicator, the data packet can be used as the granularity of comparison The priority of the data of the first service type and the data of the second service type, compared to the case where the granularity of the service type is always determined that the priority of a certain type of service data is higher than that of another type of service data, this embodiment can be based on Different data packets of the first service type data and the second service type data result in different determination results, so that the priority of the service type data can be determined more accurately.

Of course, the priorities of the first service type data and the second service type data can also be set or determined according to the service type as required. For example, service types with lower allowable delays have higher priority than service types with higher allowable delays. It should be noted that, in addition to determining the priority of the service type data according to the time delay allowed by the service type, the priority of the service type data may also be determined according to other parameters as needed. The correspondence between priority and service type may be pre-configured by the base station to the user equipment, so that when the user equipment sends the first service type data, it may be determined according to the correspondence that the first service type data belongs to the first service type, thereby determining The priority of the first service type data.

Optionally, the configuration information further includes a first data packet quality of service indicator set (which can be expressed in the form of a table), and the comparison of the priority of the first service type data with the priority of the second service type data Priorities include:

In step S42, it is determined whether the data packet service quality indicator of the first service type data belongs to the first data packet service quality indicator set;

Wherein, if the data packet service quality indicator of the first service type data belongs to the first data packet service quality indicator set, it is determined that the priority of the first service type data is higher than the second service type data If the data packet service quality indicator of the first service type data does not belong to the first data packet service quality indicator set, it is determined that the priority of the second service type data is higher than that of the first service type data. The priority of the business type data.

In one embodiment, the first data packet quality of service indicator set may be carried in the configuration information, and the user equipment may according to whether the data packet quality of service indicator of the first service type data belongs to the first data packet quality of service indicator set, To determine which of the first service type data and the second service type data has a higher priority.

For example, the data packet service quality indicator of the first service type data belongs to the first data packet service quality indicator set, and it can be determined that the priority of the first service type data is higher than the priority of the second service type data, for example, the first service type The data packet service quality indicator of the data does not belong to the first data packet service quality indicator set, and it can be determined that the priority of the second service type data is higher than the priority of the first service type data.

Specifically, when the first time-frequency resource and the second time-frequency resource are the same, for example, the first data packet quality of service indicator set includes three data packet quality of service indicators, which are 1, 2, 4, and The data packet service quality indicator of a service type data is 3, which does not belong to the first data packet service quality indicator set, then it can be determined that the priority of the second service type data is higher than the priority of the first service type data, thus The second service type data can be sent on the first time-frequency resource.

Accordingly, the base station does not need to configure the priority information of the second service type data separately for different second service type data, but only needs to set a relatively fixed set of service quality indicators for the first data packet in the configuration information (it can also be based on It needs to be changed, but it is relatively fixed compared to the data of the second service type), thereby reducing the actions that need to be performed by the base station, thereby reducing the consumption of base station resources.

Optionally, the configuration information further includes a second data packet quality of service indicator set (which can be expressed in the form of a table), and the priority of the data of the first service type is compared with that of the data of the second service type. Priorities include:

In step S43, it is determined whether the data packet service quality indicator of the first service type data belongs to the second data packet service quality indicator set;

Wherein, if the data packet service quality indicator of the first service type data does not belong to the first data packet service quality indicator set, it is determined that the priority of the first service type data is higher than the second service type The priority of the data. If the data packet service quality indicator of the first service type data belongs to the first data packet service quality indicator set, it is determined that the priority of the second service type data is higher than the first service type data. The priority of the business type data.

In an embodiment, the configuration information may carry a second data packet quality of service indicator set, and the user equipment may according to whether the data packet quality of service indicator of the first service type data belongs to the second data packet quality of service indicator set, To determine which of the first service type data and the second service type data has a higher priority.

For example, the data packet service quality indicator of the first service type data belongs to the second data packet service quality indicator set, and it can be determined that the priority of the second service type data is higher than the priority of the first service type data, for example, the first service type The data packet service quality indicator of the data does not belong to the second data packet service quality indicator set, and it can be determined that the priority of the first service type data is higher than the priority of the second service type data.

Specifically, when the first time-frequency resource and the second time-frequency resource are the same, for example, the first data packet quality of service indicator set includes three data packet quality of service indicators, which are 1, 2, 4, and The data packet service quality indicator of a service type data is 3, which does not belong to the first data packet service quality indicator set, then it can be determined that the priority of the first service type data is higher than the priority of the second service type data, thus The first service type data may be sent on the first time-frequency resource.

Accordingly, the base station does not need to configure the priority information of the second service type data for different second service type data, but only needs to set a relatively fixed set of second data packet quality of service indicators in the configuration information (also can be based on It needs to be changed, but is relatively fixed compared to the data of the second service type), thereby reducing the actions that need to be performed by the base station, thereby reducing the resource consumption of the base station.

Fig. 3 is a schematic flow chart showing a method for configuring direct link resources according to an embodiment of the present disclosure. The direct link resource configuration method shown in the embodiments of the present disclosure can be applied to a base station. The base station can communicate with user equipment based on 5G NR, and the user equipment can communicate with other devices through a direct link based on 5G NR. To communicate, other devices include other user devices. The user equipment may be, for example, an electronic device such as a mobile phone, a tablet computer, and a wearable device.

In step S2', a second time-frequency resource is determined according to the information of the first time-frequency resource, where the first time-frequency resource and the second time-frequency resource are different;

In step S3', configuration information is generated according to the information of the second time-frequency resource, where the configuration information is used to instruct the user equipment to send the second service type data on the second time-frequency resource;

In step S4', the configuration information is sent to the user equipment.

In an embodiment, the base station can determine the position of the first time-frequency resource in the time domain and the frequency domain by receiving the information of the first time-frequency resource from the user equipment, so that the base station can determine the first time-frequency resource that is different from the first time-frequency resource.

In step S11', a buffer status report sent by the user equipment is received, where the buffer status report carries information of the first time-frequency resource.

Therefore, this embodiment obtains the information of the first time-frequency resource carried by receiving the buffer status report sent by the user equipment, and the user equipment does not need to separately send the information of the first time-frequency resource, so as to reduce the occupation of the uplink channel by the user equipment.

Optionally, the configuration information includes priority information of the second service type data.

Since the user equipment can determine the priority information of the data of the first service type by itself, when the first time-frequency resource and the second time-frequency resource are the same, it can be based on whether the data packet service quality indicator of the first service type belongs to The first data packet service quality indicator set is used to determine which of the first service type data and the second service type data has a higher priority.

Optionally, the configuration information further includes a second data packet quality of service indicator set, wherein the configuration information is used to indicate that the user equipment belongs to the data packet service of the second data packet quality of service indicator set The priority of the first service type data corresponding to the quality indicator is lower than the priority of the second service type data.
