Description

[0001] Divisional Application Instructions

[0002] This application is a divisional application of Chinese Patent Application No. 201980000813.1, filed on May 9, 2019, entitled "Direct Link Data Transmission and Direct Link Resource Configuration Method and Apparatus". Technical Field

[0003] In a sidelink communication scenario, user equipment can communicate using two methods: first, by using resources dynamically scheduled by the base station; and second, by using resources selected autonomously.

[0004] In existing technologies, such as 4G-based direct link communication scenarios, due to the low requirements for QoS (Quality of Service), user equipment uses only one communication method for different types of service data.

[0005] However, in 5G-based direct link communication scenarios, due to the high QoS requirements, user equipment needs to use different communication methods for different types of service data. This may result in the same resource being used for communication using the first method and the same resource being used for communication using the second method. This makes it impossible for the user equipment to determine which communication method to use to send which type of service data on this resource, resulting in data transmission failure. Background Technology

[0055] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0056] Figure 1 This is a schematic flowchart illustrating a direct link data transmission method according to embodiments of the present disclosure. The direct link data transmission method shown in the embodiments of the present disclosure can be applied to user equipment, which can communicate with other devices via a direct link based on 5G NR (New Radio), including base stations and other user equipment. The user equipment can be, for example, electronic devices such as mobile phones, tablets, and wearable devices.

[0057] like Figure 1 As shown, the direct link data transmission method may include the following steps:

[0058] In step S1, configuration information sent by the base station is received, wherein the configuration information is used to instruct the user equipment to send second service type data in the second time-frequency resource, and the configuration information includes priority information of the second service type data;

[0059] Based on the BSR (Buffer Status Report) sent by the user equipment, the base station can determine how to configure the second time-frequency resource for the user. After determining the second time-frequency resource, the base station can generate configuration information based on the information of the second time-frequency resource, wherein the configuration information is used to instruct the user equipment to send second service type data on the second time-frequency resource.

[0060] In one embodiment, the second time-frequency resource may occupy one or more symbols or one or more subframes in the time domain, and may occupy one or more subcarriers (or subbandwidths) in the frequency domain.

[0061] In step S2, if the first time-frequency resource and the second time-frequency resource used to send the first service type data are the same, it is determined, based on the priority of the first service type data and the priority of the second service type data, whether to send the first service type data on the first time-frequency resource or to send the second service type data on the first time-frequency resource.

[0062] In one embodiment, if the second time-frequency resource is the same as the first time-frequency resource in both the frequency and time domains in each period, then it can be determined that the first time-frequency resource and the second time-frequency resource are the same; if the second time-frequency resource is different from the first time-frequency resource in either the frequency or time domain in at least one period, then it can be determined that the first time-frequency resource and the second time-frequency resource are different.

[0063] In one embodiment, if the first time-frequency resource and the second time-frequency resource used by the user equipment to send the first service type data are the same, then the user equipment cannot send the first service type data and the second service type data on different time-frequency resources respectively. Therefore, it can be determined whether to send the first service type data on the first time-frequency resource or send the second service type data on the first time-frequency resource based on the priority of the first service type data and the priority of the second service type data.

[0064] For example, if the priority of the first service type data is higher than that of the second service type data, the first service type data is transmitted on the first time-frequency resource; if the priority of the second service type data is higher than that of the first service type data, the second service type data is transmitted on the first time-frequency resource. In other words, based on the priority of the first and second service type data, the user equipment can choose to transmit the higher-priority service type data on the first time-frequency resource (i.e., the second time-frequency resource), thereby ensuring that the higher-priority service type data can be transmitted first, guaranteeing better communication performance.

[0065] Here, "first service type" and "second service type" do not necessarily refer to a specific service type, but rather represent 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 latency allowed by the first service type is relatively lower than that allowed by the second service type. In other words, the data of the first service type has a stronger urgency of transmission compared to the data of the second service type. The first time-frequency resource can be used to transmit the data. Since the first time-frequency resource can be selected autonomously by the user equipment, it can be determined more quickly than the second time-frequency resource configured by the base station through configuration information. This allows the transmission of the first service type data to be completed more quickly, which is beneficial to ensuring the latency requirements of the first service type.

[0066] Figure 2 This is a schematic flowchart illustrating another direct link data transmission method according to embodiments of the present disclosure. Figure 2 As shown, determining whether to send the first service type data or the second service type data on the first time-frequency resource based on the priority of the first service type data and the priority of the second service type data includes:

[0067] In step S21, the priority of the first service type data and the priority of the second service type data are compared;

[0068] In one embodiment, the user equipment can determine the priority information of the first service type data on its own, and then compare the priority of the first service type data with the priority of the second service type data.

[0069] In step S22, if 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 transmitted on the first time-frequency resource; if the priority of the second service type data is higher than the priority of the first service type data, the second service type data is transmitted on the first time-frequency resource.

[0070] 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 transmitted on the first time-frequency resource; when the priority of the second service type data is higher than the priority of the first service type data, the second service type data is transmitted on the first time-frequency resource. That is, based on the comparison result of the priority of the first service type data and the priority of the second service type data, the user equipment can choose to transmit the service type data with higher priority on the first time-frequency resource, thereby ensuring that the service type data with higher priority can be transmitted first and ensuring better communication effect.

[0071] Figure 3This is a schematic flowchart illustrating yet another direct link data transmission method according to embodiments of this disclosure. Figure 3 As shown, comparing the priority of the first business type data and the priority of the second business type data includes:

[0072] In step S211, the packet service quality indicator of the first service type data and the packet service quality indicator of the second service type data are compared.

[0073] In one embodiment, the priority of the first service type data and the priority of the second service type data can be determined by comparing the Package QoS Indicator (PQI) of the first service type data and the Package QoS Indicator of the second service type data. For example, the service type data with a larger Package QoS Indicator has a higher priority.

[0074] Specifically, when the first and second time-frequency resources are the same, for example, if the data packet quality of service indicator for the first service type data is 2 and the data packet quality of service indicator for 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 that of the first service type data, so the second service type data can be sent on the first time-frequency resource.

[0075] The configuration information carrying the packet quality of service indicator can be downlink control information, or DCI for short, such as DCI-5.

[0076] Since the quality of service (QoS) of different data packets can vary for the same type of data, and different data packets can correspond to different QoS indicators, the priority of the first type of data and the second type of data can be compared at the granularity of data packets based on the QoS indicator. Compared to the case where the priority of one type of data is always determined to be higher than that of another type of data at the granularity of business type, this embodiment can obtain different judgment results based on the different data packets of the first type of data and the second type of data, thereby more accurately determining the priority of the business type data.

[0077] Of course, the priority of the first service type data and the second service type data can also be set or determined according to the service type. For example, service types with lower allowable latency have higher priority than service types with higher allowable latency. It should be noted that, in addition to determining the priority of service type data based on the allowable latency of the service type, other parameters can also be used as needed. The correspondence between priority and service type can be pre-configured by the base station to the user equipment. Thus, when the user equipment sends first service type data, the correspondence can be used to determine that the first service type data belongs to the first service type, thereby determining the priority of the first service type data.

[0078] Figure 4 This is a schematic flowchart illustrating yet another direct link data transmission method according to embodiments of this disclosure. Figure 4 As shown, the priority information of the second service type data includes a set of data packet quality of service indicators, and the comparison of the priority of the first service type data and the priority of the second service type data includes:

[0079] In step S212, the relationship between the priority of the first service type data and the priority of the second service type data is determined based on the relationship between the packet service quality indicator of the first service type data and the packet service quality indicator set.

[0080] In one embodiment, the configuration information may carry a set of packet quality of service indicators. The user equipment can determine which has a higher priority, the first service type data or the second service type data, based on the relationship between the packet quality of service indicator of the first service type data and the set of packet quality of service indicators (e.g., whether the packet quality of service indicator of the first service type data belongs to the set).

[0081] Figure 5 This is a schematic flowchart illustrating yet another direct link data transmission method according to embodiments of this disclosure. Figure 5 As shown, the priority information of the second service type data includes a first data packet quality of service indicator set (which can be represented in tabular form). The step of determining the relationship between the priority of the first service type data and the priority of the second service type data based on the relationship between the data packet quality of service indicators of the first service type data and the data packet quality of service indicator set includes:

[0082] In step S2121, it is determined 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;

[0083] Specifically, if the packet service quality indicator of the first service type data belongs to the first packet service quality indicator set, the priority of the first service type data is determined to be higher than the priority of the second service type data; if the packet service quality indicator of the first service type data does not belong to the first packet service quality indicator set, the priority of the second service type data is determined to be higher than the priority of the first service type data.

[0084] In one embodiment, the configuration information may carry a first set of data packet quality of service indicators. The user equipment can determine which has a higher priority, the first service type data or the second service type data, based on whether the data packet quality of service indicator of the first service type data belongs to the first set of data packet quality of service indicators.

[0085] For example, if the packet service quality indicator of the first service type data belongs to the first packet service quality indicator set, it can be determined that the priority of the first service type data is higher than the priority of the second service type data. If the packet service quality indicator of the first service type data does not belong to the first packet service quality indicator set, it can be determined that the priority of the second service type data is higher than the priority of the first service type data.

[0086] Specifically, when the first time-frequency resource and the second time-frequency resource are the same, for example, if the first data packet service quality indicator set contains 3 data packet service quality indicators, namely 1, 2, and 4, and the data packet service quality indicator for the first 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 that of the first service type data, so the second service type data can be sent on the first time-frequency resource.

[0087] 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. Instead, it only needs to set a relatively fixed set of first data packet service quality indicators in the configuration information (which can also be changed as needed, but is relatively fixed relative to the second service type data), thereby reducing the actions that the base station needs to perform and thus reducing the consumption of base station resources.

[0088] Figure 6 This is a schematic flowchart illustrating yet another direct link data transmission method according to embodiments of this disclosure. Figure 6As shown, the priority information of the second service type data includes a second set of data packet quality of service indicators (which can be represented in tabular form). The step of determining the relationship between the priority of the first service type data and the priority of the second service type data based on the relationship between the data packet quality of service indicators of the first service type data and the set of data packet quality of service indicators includes:

[0089] In step S2122, it is determined 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;

[0090] Specifically, if the packet service quality indicator of the first service type data does not belong to the first packet service quality indicator set, the priority of the first service type data is determined to be higher than the priority of the second service type data; if the packet service quality indicator of the first service type data belongs to the first packet service quality indicator set, the priority of the second service type data is determined to be higher than the priority of the first service type data.

[0091] In one embodiment, the configuration information may carry a second set of data packet quality of service indicators. The user equipment can determine which has a higher priority, the first service type data or the second service type data, based on whether the data packet quality of service indicator of the first service type data belongs to the second set of data packet quality of service indicators.

[0092] For example, if the data packet quality of service indicator of the first service type belongs to the set of second data packet quality of service indicators, it can be determined that the priority of the second service type data is higher than that of the first service type data. Conversely, if the data packet quality of service indicator of the first service type data does not belong to the set of second data packet quality of service indicators, it can be determined that the priority of the first service type data is higher than that of the second service type data.

[0093] Specifically, when the first time-frequency resource and the second time-frequency resource are the same, for example, if the first data packet service quality indicator set contains 3 data packet service quality indicators, namely 1, 2, and 4, and the data packet service quality indicator for the first 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 that of the second service type data, so the first service type data can be sent on the first time-frequency resource.

[0094] Therefore, the base station does not need to configure the priority information of the second service type data separately for different second service type data. Instead, it only needs to set a relatively fixed set of second data packet service quality indicators in the configuration information (which can also be changed as needed, but is relatively fixed relative to the second service type data), thereby reducing the actions that the base station needs to perform and thus reducing the consumption of base station resources.

[0095] Figure 7 This is a schematic flowchart illustrating yet another direct link data transmission method according to embodiments of this disclosure. Figure 7 As shown, the method further includes:

[0096] In step S3, if the first time-frequency resource and the second time-frequency resource are different, 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.

[0097] In one embodiment, the first time-frequency resource can be selected autonomously by the user equipment. For example, the base station can configure a resource pool for the user equipment in advance or in real time, and the resource pool includes one or more time-frequency resources. The first time-frequency resource can be selected autonomously by the user equipment from the resource pool.

[0098] In one embodiment, the first time-frequency resource may occupy one or more symbols or one or more subframes in the time domain, and may occupy one or more subcarriers (or subbandwidths) in the frequency domain.

[0099] In one embodiment, if the first time-frequency resource and the second time-frequency resource used to send the first service type data are different, then the first service type data can be sent on the first time-frequency resource and the second service type data can be sent on the second time-frequency resource. This allows the first service type data and the second service type data to be sent on different time-frequency resources respectively, ensuring that both types of service data can be sent smoothly, thereby guaranteeing good communication performance for the user equipment.

[0100] For example, if 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 a time-frequency resource other than sub-bandwidth 13 and sub-frame 3 for at least one period. Thus, the user equipment can send the first type of service data on sub-bandwidth 13 and sub-frame 3 in at least one period, and send the second type of service data outside of sub-bandwidth 13 and sub-frame 3.

[0101] Figure 8This is a schematic flowchart illustrating a direct link resource configuration method according to embodiments of this disclosure. The direct link data transmission method shown in the embodiments of this disclosure can be applied to a base station, which can communicate with user equipment based on 5G NR, and the user equipment can communicate with other devices via a direct link based on 5G NR, including other user equipment. The user equipment can be, for example, electronic devices such as mobile phones, tablets, and wearable devices.

[0102] like Figure 8 As shown, the direct link resource configuration method may include the following steps:

[0103] In step S1', configuration information is generated based on the information of the second time-frequency resource and the priority information of the second time-frequency resource, wherein the configuration information is used to instruct the user equipment to send the second service type data according to the priority of the second service type data;

[0104] In step S2', the configuration information is sent to the user equipment.

[0105] In one embodiment, the base station instructs the user equipment to send the second service type data according to the priority of the second service type data through configuration information. This allows the user equipment to determine whether to send the first service type data or the second service type data on the first time-frequency resource when the first time-frequency resource and the second time-frequency resource are the same, based on the priority of the first service type data and the priority of the second service type data. This ensures that the service type data with higher priority can be sent first, guaranteeing better communication performance.

[0106] Optionally, the priority information of the second time-frequency resource includes the packet service quality indicator of the second service type data.

[0107] In one embodiment, the priority of the second service type data is represented by a packet quality of service indicator. Since the packet quality of service indicator of the first service type data can be determined by the user equipment itself, the user equipment can determine which service type data has a higher priority by comparing the packet quality of service indicator of the first service type data and the packet quality of service indicator of the second service type data.

[0108] Optionally, the priority information of the second service type data includes a set of packet service quality indicators.

[0109] In one embodiment, the configuration information may carry a set of packet quality of service indicators. The user equipment can determine which has a higher priority, the first service type data or the second service type data, based on the relationship between the packet quality of service indicator of the first service type data and the set of packet quality of service indicators (e.g., whether the packet quality of service indicator of the first service type data belongs to the set).

[0110] Optionally, the priority information of the second service type data includes a first set of data packet quality of service indicators, wherein the configuration information is used to indicate to the user equipment that the priority of the first service type data corresponding to the data packet quality of service indicator belonging to the first set of data packet quality of service indicators is higher than the priority of the second service type data.

[0111] In one embodiment, the base station may send configuration information to the user equipment that always carries the first data packet quality of service indicator set for a period of time, or it may carry the first data packet quality of service indicator set in the configuration information only when it is determined that the first time-frequency resource and the second time-frequency resource are the same.

[0112] Since the user equipment can determine the priority information of the first service type data itself, and thus, when the first time-frequency resource and the second time-frequency resource are the same, it can determine which service type data has a higher priority based on whether the data packet service quality indicator of the first service type data belongs to the first data packet service quality indicator set.

[0113] Optionally, the priority information of the second service type data includes a second set of data packet quality of service indicators, wherein the configuration information is used to indicate to the user equipment that the priority of the first service type data corresponding to the data packet quality of service indicator belonging to the second set of data packet quality of service indicators is lower than the priority of the second service type data.

[0114] In one embodiment, the base station may send configuration information to the user equipment that always carries the second data packet quality of service indicator set for a period of time, or it may carry the second data packet quality of service indicator set in the configuration information only when it is determined that the first time-frequency resource and the second time-frequency resource are the same.

[0115] Since the user equipment can determine the priority information of the first service type data itself, and thus, when the first time-frequency resource and the second time-frequency resource are the same, it can determine which service type data has a higher priority based on 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.

[0127] Specifically, if the packet service quality indicator of the first service type data belongs to the first packet service quality indicator set, the priority of the first service type data is determined to be higher than the priority of the second service type data; if the packet service quality indicator of the first service type data does not belong to the first packet service quality indicator set, the priority of the second service type data is determined to be higher than the priority of the first service type data.

[0128] Optionally, the priority information of the second service type data includes a second set of data packet quality of service indicators, and the comparison submodule is configured to determine whether the data packet quality of service indicator of the first service type data belongs to the second set of data packet quality of service indicators.

[0129] Specifically, if the packet service quality indicator of the first service type data does not belong to the first packet service quality indicator set, the priority of the first service type data is determined to be higher than the priority of the second service type data; if the packet service quality indicator of the first service type data belongs to the first packet service quality indicator set, the priority of the second service type data is determined to be higher than the priority of the first service type data.
