With the continuous growth of the number of terminals and the increase of mobile data services, the resources of the licensed frequency band are increasingly scarce. Deploying D2D communication in the licensed frequency band will undoubtedly increase the pressure on the licensed network, so consider deploying D2D in the unlicensed frequency band.

However, although D2D-U devices use the LBT competition mechanism to ensure that WiFi devices can access the channel, for scenarios where D2D-U devices are densely deployed, each D2D-U device uses the LBT competition mechanism for channel idle detection, which is prone to resource collisions and waste, greatly reducing the success rate of D2D-U and WiFi devices accessing the channel, and the channel utilization rate is low.

Detailed ways

In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

The terms "comprising" and "having" in the description, claims, and the above-mentioned drawings of the embodiments of the present application and any modifications thereof are intended to cover non-exclusive inclusion, for example, a process including a series of steps or units, A method, system, product or device is not necessarily limited to those steps or units expressly listed, but may include other steps or units not expressly listed or inherent to the process, method, product or device.

It should be understood that the "instruction" mentioned in the embodiments of the present application may be a direct instruction, an indirect instruction, or an associated relationship. For example, if A indicates B, it can indicate that A directly indicates B, for example, B can be obtained through A; it can also indicate that A indicates B indirectly, such as A indicates C, and B can be obtained through C; it can also indicate that there is an association between A and B relation.

In order to cope with the explosive growth of users' mobile bandwidth and improve spectral efficiency, the 3rd generation partnership project (3GPP) proposed a device to device (Device to Device) based on Long Term Evolution (LTE). D2D) communication, and in the Release12 version, the TR36.843 technical report named LTE Device to Device Proximity Services was formulated. D2D refers to direct communication between user communication devices within a certain distance, without the need for relaying by base stations. Compared with direct communication technologies such as Bluetooth and Wi-Fi, D2D has more advantages and flexibility. It can communicate under the control of the base station or without network infrastructure. D2D can reduce the burden on cellular networks, reduce battery power consumption of mobile terminals, increase bit rates, improve robustness to network infrastructure failures, support new small-scale peer-to-peer data services, and more.

Due to the bandwidth limitation of licensed spectrum, the improvement of D2D is limited. 3GPP has successively proposed long-term evolution standard access to unlicensed frequency bands (LTE in Unlicensed Spectrum, LTE-U) and Licensed Assisted Access (License Assist Access, LAA), both of which use unlicensed spectrum to relieve congestion. With the satisfactory performance shown by these two technologies, D2D-U naturally becomes a solution to further increase the system throughput.

In the unlicensed frequency band, WiFi devices use CSMA/CA to access and select channels, and the core is the LBT mechanism. In order not to interfere with existing Wi-Fi devices, the D2D-U device also adopts the LBT mechanism when selecting a channel, that is, it monitors before accessing a channel and selects an idle channel for access.

Considering that each D2D-U device performs channel idle detection alone, which is likely to cause resource collision and waste, the embodiment of the present application proposes a resource scheduling scheme based on a communication group, and divides multiple D2D-U devices into the same communication group based on distance ( Or called group, cluster), the group head (cluster header, or called cluster head) of the communication group performs channel detection and competition, and after obtaining channel resources, allocates time-frequency to other D2D-U devices in the communication group Domain resources, the scheduling scheme can effectively reduce the number of adjacent competitors on the same channel, reduce the collision probability, and improve channel utilization.

Exemplarily, FIG. 1 is a schematic diagram of a grouping of D2D-U devices provided by an embodiment of the present application. As shown in FIG. 1 , a large number of D2D-U devices are distributed in a cell covered by a base station, and D2D-U devices with similar locations are grouped together. In the same communication group, that is, D2D devices whose mutual distance value is less than the preset distance are grouped into the same communication group. A group head device is selected from all D2D-U devices in each communication group through the set selection strategy. In some embodiments, when a new communication group is formed, the cell base station may determine the group head device of the communication group. For example, select the D2D-U device with the largest number of direct adjacent devices as the group head device, or select the D2D-U device with the most remaining power as the group head device, or select the channel state information (Channel State Information) with the base station. , CSI) the best D2D-U device as the group head device, or, select the D2D-U device with the largest device memory as the group head device.

The purpose of grouping D2D-U devices is to group D2D-U devices that may interfere with each other into the same communication group, and the group head device represents this communication group to perform channel competition and resource allocation, so as to avoid intra-group communication. interference, and avoid excessive D2D-U device competition, which will seriously degrade WiFi performance.

The group head device of the communication group uses the LBT mechanism for channel detection and competition. After obtaining the right to use the channel, it needs to allocate time-frequency domain resources to other D2D-U devices in the communication group. How to allocate can improve channel utilization, and how to allocate It is an urgent problem to be able to reduce the interference to the WiFi system as much as possible.

In view of the above problems, an embodiment of the present application proposes a method for determining resource scheduling, which can be applied to a D2D device unlicensed frequency band communication scenario. In the unlicensed frequency band, the inventor considers that the loads of the D2D-U system and the WiFi system usually change dynamically. By monitoring the loads of the D2D-U system and the WiFi system, the load of the two communication systems is not balanced. , according to the load changes of the two communication systems, dynamically adjust the resource scheduling strategy in the D2D-U communication group, and reduce the impact on the WiFi system as much as possible while improving the channel utilization rate. The embodiment of the present application provides two resource scheduling strategies: one is a first resource scheduling strategy in the frequency domain and then the time domain, and the other is a second resource scheduling strategy in the time domain and then the frequency domain. When the WiFi system load is high and/or the D2D-U system load is low, the first resource scheduling strategy can be adopted; when the WiFi system load is low and/or the D2D-U system load is high, the second resource scheduling strategy can be adopted. The above-mentioned resource scheduling scheme can be applied to D2D-U devices, and can also be applied to network devices, such as base stations.

No longer.

FIG. 3 is a schematic flowchart of a method for determining resource scheduling provided by an embodiment of the present application. As shown in FIG. 3 , the determination method provided in this embodiment may be applied to the first communication device of the first communication system, where the first communication device may be the network device shown in FIG. 1 , or the D2D shown in FIG. 2 . equipment.

Specifically, the method includes the following steps:

Step 201: Acquire the load conditions of the first communication system and the second communication system.

The first communication system and the second communication system both use unlicensed frequency bands for data communication. The load condition of the communication system is used to indicate the number of load devices, the amount of data transmission, etc. in the communication system.

In an embodiment of the present application, the first communication system is a D2D system, and the second communication system is a WiFi system. Correspondingly, the first communication device of the first communication system is a D2D device. Since the first communication system uses an unlicensed spectrum for data communication, the first communication device is also called a D2D-U device. Exemplarily, the first communication device is a group head terminal device of any communication group in the D2D system. The first communication device performs channel detection and competition, and after obtaining channel resources, allocates time-frequency domains to other communication devices in the communication group. resource. The communication device of the second communication system is a WiFi device.

In an embodiment of the present application, the first communication system is an LTE-U system, and the second communication system is a WiFi system. Correspondingly, the first communication device of the first communication system may be a network device of the LTE-U system, such as a base station. The communication device of the second communication system is a WiFi device.

It should be understood that the first communication system and the second communication system in this embodiment may also be other communication systems using an unlicensed frequency band, which is not limited in this embodiment.

In this embodiment, the first communication device of the first communication system competes with the communication device of the second communication system for the right to use the channel. After obtaining the right to use the channel, the first communication device can perform fine-grained division of the channels, and each channel occupies The duration COT may be divided into multiple time units and multiple frequency domain units, and after the resource scheduling policy determined in step 302 is used, time-frequency domain resources are allocated to other communication devices in the first communication system.

Exemplarily, FIG. 4 is a schematic structural diagram of a channel resource provided by an embodiment of the present application. As shown in FIG. 4 , after the first communication device successfully competes with the communication device of the second communication system for the channel use right, the channel use right is obtained. It is assumed that The longest channel occupied time is COT, and the channel bandwidth is W. The first communication device divides the time-frequency domain resources in a fine-grained manner: the time domain is divided according to time slots and divided into 4 time slots as shown in Figure 4; the frequency domain is divided according to The preset bandwidth is divided into 5 sub-channels as shown in FIG. 4 .

It should be noted that the time unit in this embodiment may be a radio frame, subframe, time slot, etc., which is not limited in this embodiment. The frequency domain unit in this embodiment may be a resource block RB, a resource block group (RB group, RBG), a subchannel (subchannel), etc., where the RBG includes multiple RBs, and the subchannel includes multiple consecutive RBGs. This embodiment does not impose any limitation on the frequency domain unit.

Step 202: Determine a resource scheduling policy according to the load conditions of the first communication system and the second communication system.

In an embodiment of the present application, according to the obtained load conditions of the first communication system and the second communication system, if the load of the first communication system is less than the first threshold, and/or the load of the second communication system is greater than or equal to the first Second threshold, it can be determined to adopt the first resource scheduling policy. That is, if the load of the first communication system is high, the first resource scheduling strategy can be adopted; or, if the load of the first communication system is high and the load of the second communication system is low, the first resource scheduling strategy can be adopted; or, If the load of the second communication system is low, the first resource scheduling strategy may be adopted.

The first resource scheduling strategy is to schedule different frequency domain resources of the same time unit until all the frequency domain resources of the time unit are allocated, and then schedule the frequency domain resources of the next time unit adjacent to the time unit. The first resource scheduling strategy is a resource scheduling strategy in the frequency domain and then the time domain.

As an example, after obtaining the channel use right, the first communication device may schedule the time-frequency domain resources shown in FIG. 4 to other communication devices in the first communication system. When the first communication device allocates resources to other communication devices of the first communication system, it tries to schedule the communication devices on different sub-channels of the same time slot, and does not start scheduling the next time slot until all the sub-channels of the time slot have been allocated. gap.

Exemplarily, FIG. 5 is a schematic diagram of a resource scheduling strategy provided by an embodiment of the present application. As shown in FIG. 5 , it is assumed that in addition to the first communication device, there are 6 communication devices in the first communication system that require resource scheduling, The first communication device schedules 5 communication devices on different sub-channels of the first time slot, such as the 5 sub-channels of time slot 1 in Fig. 5, since all sub-channels of the first time slot have been allocated, The sixth communication device is scheduled in one of the subchannels of the next time slot, such as subchannel 5 of time slot 2 in FIG. 5 . As an example, one sub-channel may be randomly selected from the five sub-channels in the next time slot and allocated to the sixth communication device. As another example, one sub-channel with the best channel quality may be selected from the 5 sub-channels in the next time slot according to the channel quality.

It can be seen from the above embodiments that the first resource scheduling strategy is a scheduling strategy in the frequency domain and then in the time domain, and the scheduling strategy can reduce the waiting time of a communication device in the first communication system, such as a D2D-U device, and reduce the impact on the second communication system. impact on system performance. Using the first resource scheduling strategy, within the COT time, if there is a device in the second communication system, such as a WiFi device, competing for channel resources, the WiFi device can take away the channel use right in the time unit where no communication device is allocated, so that The first communication system cannot fully utilize the frequency domain resources of the COT duration, but has little impact on the access of the WiFi device.

In an embodiment of the present application, according to the obtained load conditions of the first communication system and the second communication system, if the load of the first communication system is greater than or equal to the first threshold, and/or the load of the second communication system is less than the first threshold The second threshold can be determined to adopt the second resource scheduling policy. That is, if the load of the first communication system is low, the second resource scheduling strategy can be adopted; or, if the load of the first communication system is low and the load of the second communication system is high, the second resource scheduling strategy can be adopted; or, If the load of the second communication system is high, the second resource scheduling strategy may be adopted.

Optionally, in some embodiments, if the load of the first communication system is greater than or equal to the eighth threshold, and/or the load of the second communication system is less than the ninth threshold, it may be determined to adopt the second resource scheduling policy. In some embodiments, the eighth threshold and the first threshold may be the same, and the ninth threshold and the second threshold may be the same. In some embodiments, the eighth threshold may be greater than the first threshold, and the ninth threshold may be less than the second threshold.

The second resource scheduling strategy is to schedule different time units of the same frequency domain unit until all time units of the channel occupation duration COT of the frequency domain unit are allocated, and then schedule other frequency domain units. The second resource scheduling strategy is a resource scheduling strategy in which the time domain is first followed by the frequency domain.

As an example, after obtaining the channel use right, the first communication device may schedule the time-frequency domain resources shown in FIG. 4 to other communication devices in the first communication system. When allocating resources to other communication devices of the first communication system, the first communication device tries to schedule the communication devices in different time slots of the same sub-channel, and does not start to schedule other sub-channels until all the time slots of the COT are occupied.

Exemplarily, FIG. 6 is a schematic diagram of a resource scheduling strategy provided by an embodiment of the present application. As shown in FIG. 6 , it is assumed that in addition to the first communication device, there are 5 communication devices in the first communication system that require resource scheduling, The first communication device schedules 4 communication devices in different time slots of the same subchannel, for example, the 4 time slots of subchannel 5 in FIG. The communication device is scheduled on other subchannels, for example, time slot 1 of subchannel 3 in FIG. 6 , or other time slots of subchannel 3 .

In some embodiments, if there are 7 communication devices in the first communication system that need resource scheduling, when 4 communication devices are scheduled in different time slots of the same subchannel, for example, 4 time slots of subchannel 1 in FIG. 6 , The remaining two communication devices are allocated to different time slots of the same subchannel, for example, time slot 1 and time slot 2 of subchannel 3 in FIG. 6 . Optionally, the remaining two communication devices are allocated to different sub-channels of the same time slot, for example, sub-channel 2 and sub-channel 3 of time slot 2 in FIG. 6 .

It can be seen from the above embodiment that the second resource scheduling strategy is a scheduling strategy in which the time domain is first followed by the frequency domain. This scheduling strategy can make full use of the COT duration to ensure that the WiFi device does not steal the channel use right as much as possible within the COT duration. Communication devices of the first communication system within which the data is generated have more opportunities to use this COT duration.

Exemplarily, assuming that in the third time slot, the first communication device learns that there is a communication device that has data to be transmitted in the first communication system, under the second resource scheduling strategy of the time domain first and the frequency domain, the first communication device can notify The communication device to transmit data uses the channel resources of the fourth time slot, but under the first resource scheduling strategy of the frequency domain first and then the time domain, if the WiFi device of the second communication system competes for the channel in the third time slot, then The channel resource of the fourth time slot is very likely to be preempted by the WiFi device, so that the channel resource cannot be allocated to the communication device that is to transmit data in the first communication system.

In the method for determining resource scheduling provided by this embodiment, the resource scheduling policy is determined according to the load conditions of the first communication system and the second communication system by acquiring the load conditions of the first communication system and the second communication system. If the load of the first communication system is less than the first threshold, and/or the load of the second communication system is greater than or equal to the second threshold, it is determined to adopt the first resource scheduling strategy in the frequency domain and then the time domain; If the load of the system is greater than or equal to the first threshold, and/or the load of the second communication system is less than the second threshold, it is determined to adopt the second resource scheduling strategy in the time domain and then the frequency domain. The above method can reduce the impact of the first communication system on the second communication system as much as possible while making full use of time-frequency domain resources.

Based on the foregoing embodiments, the following describes in detail how the first communication device acquires the load of the first communication system in the foregoing embodiments through several specific embodiments.

The first communication device may determine the load situation of the first communication system through the following two implementation manners or a combination of the two implementation manners.

In a possible implementation manner, the first communication device acquires the load condition of the first communication system through information interaction with at least one second communication device. Both the first communication device and the second communication device for information exchange belong to the first communication system.

As an example, the first communication system is a D2D system, the first communication device and at least one second communication device are in the same communication group, the first communication device is a group head terminal device of the communication group, and at least one second communication device is a communication group other end devices of the group.

As an example, the first communication system is an LTE/D2D system, the first communication device is a network device of the LTE/D2D system, such as a base station, and at least one second communication device is a communication device/D2D within the coverage of the first communication device equipment.

In an embodiment of the present application, the first communication device acquires the load condition of the first communication system through information interaction with at least one second communication device, including: the first communication device receives feedback information from each second communication device , the feedback information is used to indicate the amount of data to be transmitted by each second communication device, and the load condition of the first communication system is determined according to the feedback information of each second communication device.

In an embodiment of the present application, the first threshold includes a third threshold, the first communication device determines a total data volume of data to be transmitted by at least one second communication device, and determines the first communication system according to the total data volume and the third threshold load situation.

Specifically, if the total data amount is greater than or equal to the third threshold, it is determined that the load of the first communication system is high; or, if the total data amount is less than the third threshold, it is determined that the load of the first communication system is low.

In the above embodiment, the load of the first communication system is determined by acquiring the total data volume of data to be transmitted by at least one second communication device interacting with the first communication device, and the total data volume can be used to characterize the load level of the first communication system. .

In a possible implementation manner, the first communication device acquires the number of devices of the first communication system, and determines the load condition of the first communication system according to the number of devices.

As an example, the first communication system is a D2D system, the first communication device and at least one second communication device are in the same communication group, the first communication device is a group head terminal device of the communication group, and at least one second communication device is a communication group other end devices of the group.
