投屏方法及5G终端Screen projection method and 5G terminal

技术领域technical field

本发明实施例涉及通信技术领域，尤其涉及一种投屏方法及5G终端。Embodiments of the present invention relate to the field of communication technologies, and in particular, to a screen projection method and a 5G terminal.

背景技术Background technique

目前的投屏技术方案，主要包括DLNA(Digital Living Network Alliance，数字家庭网络联盟)、AirPlay(隔空播放)、Miracast(由Wi-Fi联盟于2012年所制定，以Wi-Fi直连(Wi-Fi Direct)为基础的无线显示标准)。The current screen projection technology solutions mainly include DLNA (Digital Living Network Alliance, Digital Home Network Alliance), AirPlay (airplay), Miracast (developed by the Wi-Fi Alliance in 2012, using Wi-Fi direct connection (Wi-Fi) -Fi Direct) based wireless display standard).

其中，DLNA可以将图片和视频共享给大屏幕播放，但是其没有镜像功能，无法将终端屏幕内容同步到大屏幕中；AirPlay具备DLNA所没有的镜像功能，可将苹果设备(例如iPhone或iPad)上的画面无线传输到电视上，也就是说终端设备显示的是什么，电视屏幕显示的就是什么，而不仅限于图片和视频；Miracast是由Wi-Fi联盟于2012年所制定，以Wi-Fi直连为基础的无线显示标准。支持此标准的设备可通过无线方式分享视频画面，例如手机可通过Miracast将影片或照片直接在电视或其他装置播放而无需受到连接线缆长度的影响。与DLNA不同的是，Miracast也有类似于AirPlay的镜像功能，可以将手机中屏幕内容直接投放到高清电视屏幕里。Among them, DLNA can share pictures and videos to the big screen for playback, but it has no mirroring function and cannot synchronize the terminal screen content to the big screen; AirPlay has the mirroring function that DLNA does not have, which can be used for Apple devices (such as iPhone or iPad) The picture on the screen is wirelessly transmitted to the TV, that is to say, what is displayed on the terminal device, what is displayed on the TV screen, not only limited to pictures and videos; Miracast was formulated by the Wi-Fi Alliance in 2012, based on Wi-Fi Direct-connect-based wireless display standard. Devices that support this standard can share video images wirelessly. For example, mobile phones can play videos or photos directly on TV or other devices through Miracast without being affected by the length of the connecting cable. Unlike DLNA, Miracast also has a mirroring function similar to AirPlay, which can directly cast the screen content of the mobile phone to the high-definition TV screen.

那么目前的上述三种投屏方案都是以将终端信号经由Wi-Fi传输到电视、电视盒的方式来实现终端向电视或电视盒的投屏的，这种通过Wi-Fi的投屏方案只可以由终端单点投屏到一个设备，而无法实现终端向多个设备的投屏。Then the above three current screen projection solutions all realize the screen projection of the terminal to the TV or TV box by transmitting the terminal signal to the TV and TV box via Wi-Fi. This kind of screen projection solution through Wi-Fi It is only possible to project the screen from the terminal to one device at a single point, and it is not possible to project the screen from the terminal to multiple devices.

具体实施方式Detailed ways

下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

参照图1，示出了本发明一个实施例的投屏方法的流程图，应用于5G(第五代移动通信网络)终端，所述方法具体可以包括如下步骤：Referring to FIG. 1, a flowchart of a screen projection method according to an embodiment of the present invention is shown, which is applied to a 5G (fifth generation mobile communication network) terminal. The method may specifically include the following steps:

步骤101，若检测到第一投屏设备的5G投屏请求，则判断通过5G双向通信天线已连接的第二投屏设备的数量n是否大于或等于5G双向通信天线的总数量m；Step 101, if the 5G screen projection request of the first screen projection device is detected, determine whether the number n of the second screen projection devices connected through the 5G bidirectional communication antenna is greater than or equal to the total number m of the 5G bidirectional communication antenna;

若是，则执行步骤301，拒绝所述5G投屏请求，或，利用时分多址技术或利用频分多址技术对所述第一投屏设备分配目标5G双向通信天线(即，执行下述步骤102或下述步骤103或下述步骤104)；If so, go to step 301 to reject the 5G screen projection request, or use time division multiple access technology or frequency division multiple access technology to allocate a target 5G two-way communication antenna to the first screen projection device (that is, perform the following steps 102 or the following step 103 or the following step 104);

若否，则执行步骤302，检测所述第一投屏设备以及每个第二投屏设备所需要传输的数据量，根据所述数据量，对所述第一投屏设备分配目标5G双向通信天线，或，利用时分多址技术或利用频分多址技术对所述第一投屏设备分配目标5G双向通信天线(即，执行下述步骤105或下述步骤103或下述步骤104)。If not, step 302 is executed to detect the amount of data that the first screen projection device and each second screen projection device need to transmit, and according to the data amount, assign a target 5G two-way communication to the first screen projection device Antenna, or, use time division multiple access technology or use frequency division multiple access technology to allocate a target 5G bidirectional communication antenna to the first screen projection device (ie, perform the following step 105 or the following step 103 or the following step 104).

其中，n为自然数，m为正整数。where n is a natural number and m is a positive integer.

其中，5G终端具有5G天线，5G天线可以包括5G双向通信天线和5G单向通信天线。举例而言，5G天线的射频硬件链路可以包括但不限于以下几类：1T(transit，发射)4R(receive，接收)、2T4R、4T8R等。以4T8R为例，其表示该5G终端有8根天线，其中，4根天线为既可以发射数据又可以接收数据的天线，该4根天线均为5G双向通信天线，另外4根天线为只可以接收数据的天线，即该4根天线为5G单向通信天线。Among them, the 5G terminal has a 5G antenna, and the 5G antenna may include a 5G two-way communication antenna and a 5G one-way communication antenna. For example, the radio frequency hardware link of the 5G antenna may include, but is not limited to, the following categories: 1T (transit, transmit), 4R (receive, receive), 2T4R, 4T8R, and so on. Taking 4T8R as an example, it means that the 5G terminal has 8 antennas. Among them, 4 antennas are antennas that can both transmit and receive data. These 4 antennas are all 5G two-way communication antennas, and the other 4 antennas are only available. The antennas that receive data, that is, the four antennas are 5G unidirectional communication antennas.

如图2所示，以5G终端的5G天线的射频硬件链路为4T8R为例示出了5G终端与w个设备同时进行投屏的示意图。As shown in Figure 2, taking the radio frequency hardware link of the 5G antenna of the 5G terminal as 4T8R as an example, it shows a schematic diagram of the simultaneous screencasting of the 5G terminal and w devices.

如图2所示，5G终端在进行投屏业务时，5G终端需要使用至少一根5G双向通信天线(例如图2中的TR)来与投屏设备连接，来实现投屏。可选地，为了提高蜂窝下行吞吐量，还可以使5G终端的上述5G单向通信天线(例如图2中的DR)与投屏设备连接，其中，下行方向指代从与该5G终端连接的投屏设备向该5G终端传输的数据的方向。As shown in Figure 2, when the 5G terminal performs the screen projection service, the 5G terminal needs to use at least one 5G bidirectional communication antenna (such as TR in Figure 2) to connect with the screen projection device to realize the screen projection. Optionally, in order to improve the cellular downlink throughput, the above-mentioned 5G unidirectional communication antenna (for example, the DR in FIG. 2 ) of the 5G terminal can also be connected to the screen projection device, wherein the downlink direction refers to the connection from the 5G terminal connected to the 5G terminal. The direction of the data transmitted by the screen-casting device to the 5G terminal.

在本发明实施例的技术方案中，如图2所示，5G终端可以通过基站(5G基站或者4G基站均可)与远距离的配对设备(设备4～设备w)进行连接，从而将5G终端的屏幕内容的数据以超低延迟的形式实时传送给配对设备，同时又可以与近距离(利用5G的D2D(Device toDevice)技术)的配对设备直接连接，来进行投屏。In the technical solution of the embodiment of the present invention, as shown in FIG. 2 , a 5G terminal can connect with a remote paired device (device 4 to device w) through a base station (either a 5G base station or a 4G base station), so as to connect the 5G terminal The data of the screen content is transmitted to the paired device in real time in the form of ultra-low latency, and at the same time, it can be directly connected to the paired device at a short distance (using 5G's D2D (Device to Device) technology) for screen projection.

因此，本发明实施例中的不论是第一投屏设备还是第二投屏设备都是指代与5G终端通过天线直接连接的设备，因此，该第一投屏设备或者该第二投屏设备可以是终端设备也可以是基站，即本发明实施例的5G终端可以通过与基站连接来实现对侧和基站连接的多个终端设备的投屏，还可以通过直接与终端设备连接，来实现5G终端与终端设备之间的投屏。Therefore, in the embodiments of the present invention, whether it is the first screen projection device or the second screen projection device refers to a device directly connected to the 5G terminal through an antenna. Therefore, the first screen projection device or the second screen projection device It can be a terminal device or a base station, that is, the 5G terminal in the embodiment of the present invention can realize the screen projection of multiple terminal devices connected to the opposite side and the base station by connecting with the base station, and can also realize 5G by directly connecting with the terminal device. Screencasting between terminals and terminal devices.

在步骤101中，该第一投屏设备的5G投屏请求可以是5G终端向第一投屏设备发送的5G投屏请求(即5G终端向第一投屏设备进行5G投屏)，也可以是从第一投屏设备接收到的5G投屏请求(即第一投屏设备向5G终端进行5G投屏)。Instep 101, the 5G screencasting request of the first screencasting device may be a 5G screencasting request sent by the 5G terminal to the first screencasting device (that is, the 5G terminal performs 5G screencasting to the first screencasting device), or It is the 5G screen projection request received from the first screen projection device (that is, the first screen projection device performs 5G screen projection to the 5G terminal).

其中，在图2中，5G双向通信天线的总数量m＝4。5G终端至少需要1T1R(1根天线)与基站通信，保证网络功能，其余的3T3R(3根天线)可以同时连接最多3台投屏设备，剩余的4DR(4根天线)与基站连接来提高蜂窝下行(基站向5G终端发送数据)吞吐量。Among them, in Figure 2, the total number of 5G two-way communication antennas is m=4. 5G terminals need at least 1T1R (1 antenna) to communicate with the base station to ensure network functions, and the remaining 3T3R (3 antennas) can be connected to a maximum of 3 at the same time. For screen projection equipment, the remaining 4DR (4 antennas) are connected to the base station to improve the throughput of cellular downlink (the base station sends data to the 5G terminal).

例如，在步骤101中，5G终端已连接的第二投屏设备包括通过TRX2、TRX3、TRX4分别连接的设备2和设备3以及基站，因此，n＝3。For example, instep 101, the second screen projection device connected to the 5G terminal includes device 2, device 3 and base station connected through TRX2, TRX3, and TRX4 respectively, so n=3.

这里以第一投屏设备为设备1为例进行说明，显然n<m，m＝4，因此，转到执行步骤105或步骤103或步骤104。Here, the first screen projection device isdevice 1 as an example for description. Obviously, n<m, m=4. Therefore, go to step 105 or step 103 or step 104.

具体执行步骤105还是步骤103或是步骤104可以根据需要灵活配置，也可以根据用户需求来选择执行步骤105或步骤103或步骤104。The specific execution of step 105, step 103 or step 104 can be flexibly configured according to needs, and step 105 or step 103 or step 104 can also be selected to be executed according to user needs.

再如，已连接的第二投屏设备包括通过TRX2、TRX3、TRX4分别连接的设备2和设备3以及基站，还包括通过TRX1连接的设备1，则n＝4，显然n＝m，因此，转到执行步骤102或步骤103或步骤104。For another example, the connected second screen projection device includes device 2, device 3 and base station connected through TRX2, TRX3, and TRX4 respectively, and also includesdevice 1 connected through TRX1, then n=4, obviously n=m, therefore, Go to execute step 102 or step 103 or step 104.

具体执行步骤102还是步骤103或是步骤104可以根据需要灵活配置，也可以根据用户需求来选择执行步骤102或步骤103或步骤104。The specific execution of step 102, step 103 or step 104 can be flexibly configured as required, and step 102 or step 103 or step 104 can also be selected to be executed according to user requirements.

其中，步骤103和步骤104分别是利用时分多址技术、频分多址技术来与已经连接投屏设备的5G双向通信天线进行共用的方式，来实现投屏设备数量的扩展。由于在相同信道数的情况下，采用时分多址要比频分多址能容纳更多的投屏设备，因此，5G终端可以根据需要连接的第一投屏设备的数量来灵活选择执行步骤103还是执行步骤104。Wherein, step 103 and step 104 respectively utilize time division multiple access technology and frequency division multiple access technology to share with the 5G bidirectional communication antenna that has been connected to the screen projection device, so as to realize the expansion of the number of screen projection devices. Since time division multiple access can accommodate more screen projection devices than frequency division multiple access in the case of the same number of channels, the 5G terminal can flexibly choose to execute step 103 according to the number of first screen projection devices to be connected. Step 104 is still executed.

步骤102，拒绝所述5G投屏请求；Step 102, rejecting the 5G screen projection request;

其中，5G终端可以通过发送表示拒绝该5G投屏请求的反馈信息给第一投屏设备，来拒绝该5G投屏请求。The 5G terminal may reject the 5G screen projection request by sending feedback information indicating that the 5G screen projection request is rejected to the first screen projection device.

步骤103，利用时分多址技术对所述第一投屏设备分配目标5G双向通信天线；Step 103, using time division multiple access technology to allocate a target 5G two-way communication antenna to the first screen projection device;

具体而言，如图3所示，以5G终端的天线为1T4R为例，5G终端可以将一个TR在不同的时间上进行切片，分为多个时隙给多个投屏设备使用，由于各个投屏设备占用的时间不同，所以相互之间不会干扰。Specifically, as shown in Figure 3, taking the antenna of the 5G terminal as 1T4R as an example, the 5G terminal can slice a TR at different times and divide it into multiple time slots for use by multiple screen projection devices. Screen-casting devices take different time, so they will not interfere with each other.

在本实施例中，5G终端可以从已与n个第二投屏设备连接的处于已连接投屏设备状态的5G双向通信天线中，来选择一个目标5G双向通信天线来通过时分多址技术分配给该第一投屏设备使用。In this embodiment, the 5G terminal can select a target 5G two-way communication antenna from the 5G two-way communication antennas in the connected screen-casting device state that have been connected to the n second screen-casting devices to be allocated by time division multiple access technology Use it for the first screen projection device.

以图2为例，可以从4个均处于已连接投屏设备状态的TR(即TRX1、TRX2、TRX3、TRX4)中，选择一个TR来通过时分多址技术分配给该第一投屏设备使用。Taking Figure 2 as an example, from the four TRs (ie TRX1, TRX2, TRX3, TRX4) that are all connected to the screen-casting device, one TR can be selected to be allocated to the first screen-casting device through time division multiple access technology. .

可选地，在执行步骤103时，可以通过以下方式来实现：Optionally, when step 103 is executed, it can be implemented in the following manner:

判断m个5G双向通信天线中是否存在处于空闲状态的5G双向通信天线；Determine whether there is an idle 5G two-way communication antenna among the m 5G two-way communication antennas;

其中，由于n>m，说明5G终端的m个TR(即所有的TR)均已分配给投屏设备进行连接，且每个TR至少连接了一个第二投屏设备。Among them, since n>m, it means that m TRs of the 5G terminal (that is, all TRs) have been allocated to the screen projection device for connection, and each TR is connected to at least one second screen projection device.

但是，对于通过一个TR来与5G终端进行投屏连接的第二投屏设备而言，该5G终端与该第二投屏设备之间并非实时都在进行数据传输，而当该TR虽然与该第二投屏设备连接，但是当其处于未传输数据状态(即空闲状态)下时，则本发明实施例的方法可以将一个TR在不同的时间上进行切片，分为多个时隙给多个投屏设备使用，由于各个投屏设备占用的时间不同，所以相互之间不会干扰。However, for the second screen projection device that is connected to the 5G terminal for screen projection through a TR, data transmission is not performed between the 5G terminal and the second screen projection device in real time. The second screen projection device is connected, but when it is in a state of not transmitting data (ie, an idle state), the method of the embodiment of the present invention can slice a TR at different times and divide it into multiple time slots for multiple When using one screen-casting device, each screen-casting device will not interfere with each other because the time occupied by each screen-casting device is different.

因此，这里可以判断m个TR中是否存在处于空闲状态的TR。Therefore, it can be determined whether there is a TR in an idle state among the m TRs.

若是(例如m个TR中存在处于空闲状态的TR，其中，TR处于空闲状态可以是已连接投屏设备但是未与该已连接投屏设备传输任何数据而处于空闲状态，也可以是未连接任何投屏设备而处于空闲状态)，则从处于空闲状态的5G双向通信天线中随机选择一个目标5G双向通信天线分配至所述第一投屏设备；If (for example, there is a TR in an idle state among m TRs, where the TR in an idle state may be connected to a screen-casting device but has not transmitted any data with the connected screen-casting device and is in an idle state, or it may be not connected to any The screen projection device is in an idle state), randomly select a target 5G two-way communication antenna from the 5G two-way communication antennas in the idle state and assign it to the first screen projection device;

其中，当m个TR中存在处于空闲状态的TR时，则可以从处于空闲状态的TR中随机选择一个目标TR来分配给该第一投屏设备。Wherein, when there is a TR in an idle state among the m TRs, a target TR may be randomly selected from the TRs in an idle state to be allocated to the first screen projection device.

如图3所示，目标TR(这里为TRX1)已通过时分多址技术分配给基站、设备3、设备2来连接进行投屏，当前又检测到设备1的投屏请求，且检测到该投屏请求时，该目标TR处于未与基站、设备2以及设备3进行任何数据传输的状态，即空闲状态，因此，可以将该TRX1分配给设备1来进行投屏，那么在设备1与5G终端通过TRX1进行投屏的过程中，该基站、设备2以及设备3则不可以与5G终端之间传输投屏数据。待该TRX1再次处于空闲状态时，才可以切换通过TRX1进行投屏的设备，例如在时隙2切换至设备3与5G终端之间传输投屏数据。As shown in Figure 3, the target TR (here, TRX1) has been allocated to the base station, device 3, and device 2 through time division multiple access technology to connect for screen projection. Currently, the screen projection request ofdevice 1 is detected, and the projection screen is detected. When the screen is requested, the target TR is in a state of not performing any data transmission with the base station, device 2 and device 3, that is, an idle state. Therefore, the TRX1 can be allocated todevice 1 for screen projection, then betweendevice 1 and the 5G terminal In the process of screencasting through TRX1, the base station, device 2 and device 3 cannot transmit screencast data with the 5G terminal. When the TRX1 is in an idle state again, the device that performs screen projection through the TRX1 can be switched. For example, in time slot 2, switch to device 3 and transmit screen projection data between the 5G terminal.

需要说明的是，图3中每个投屏设备占用的时隙可以是固定的，也可以是可变化的(并非设备1固定于在时隙4进行数据传输，而设备2在时隙3进行数据传输)。It should be noted that the time slot occupied by each screen projection device in Figure 3 can be fixed or variable (not thatdevice 1 is fixed to perform data transmission in time slot 4, while device 2 performs data transmission in time slot 3 data transmission).

若否(例如m个TR中不存在处于空闲状态的TR)，则执行步骤104，即利用频分多址技术对所述第一投屏设备分配目标5G双向通信天线。If no (for example, there is no TR in an idle state among the m TRs), step 104 is performed, that is, a target 5G bidirectional communication antenna is allocated to the first screen projection device by using the frequency division multiple access technology.

其中，例如图2中的4个TR均没有处于空闲状态，即都在传输投屏数据，那么则难以采用时分多址技术来对第一投屏设备分配目标TR，这里，可以执行步骤104，即利用频分多址技术对所述第一投屏设备分配目标5G双向通信天线，步骤104的具体实现过程参照下述相关实施例，这里不再赘述。Among them, for example, none of the four TRs in FIG. 2 is in an idle state, that is, they are all transmitting screen projection data, then it is difficult to use the time division multiple access technology to allocate the target TR to the first screen projection device. Here, step 104 can be performed, That is, using the frequency division multiple access technology to allocate the target 5G bidirectional communication antenna to the first screen projection device, the specific implementation process of step 104 refers to the following related embodiments, which will not be repeated here.

在本发明实施例中，当通过5G双向通信天线已连接的第二投屏设备的数量n大于或等于5G双向通信天线的总数量m时，则说明5G终端的所有5G双向通信天线都已连接有投屏设备，那么为了增加同时投屏设备的数量，本发明实施例可以在一个双向通信天线的射频硬件链路的不同时隙上来传输已连接的不同投屏设备的投屏数据，从而在5G双向通信天线数量有限的情况下，增加同时投屏的投屏设备的数量。此外，还可以避免空分多址受天线数量的限制而无法扩展更多的投屏设备的问题，使得各个投屏设备通过不同的时隙与5G终端进行通信，极大的扩展了可接入的投屏设备数量。In the embodiment of the present invention, when the number n of the second screen projection devices connected through the 5G two-way communication antenna is greater than or equal to the total number m of the 5G two-way communication antenna, it means that all 5G two-way communication antennas of the 5G terminal have been connected. If there are screen projection devices, in order to increase the number of simultaneous screen projection devices, in this embodiment of the present invention, the screen projection data of different connected When the number of 5G two-way communication antennas is limited, increase the number of screen-casting devices that screen simultaneously. In addition, it can also avoid the problem that space division multiple access is limited by the number of antennas and cannot expand more screen projection devices, so that each screen projection device communicates with 5G terminals through different time slots, which greatly expands the accessibility. The number of screen-casting devices.

步骤104，利用频分多址技术对所述第一投屏设备分配目标5G双向通信天线；Step 104, using frequency division multiple access technology to allocate a target 5G two-way communication antenna to the first screen projection device;

具体而言，如图4所示，以5G终端的天线为1T4R为例，5G终端可以将一个TR在不同的频率上进行信道的划片，分为多个频率的信道来供多个投屏设备使用，由于各个投屏设备使用的信道的频率不同，所以相互之间不会干扰。Specifically, as shown in Figure 4, taking the antenna of the 5G terminal as 1T4R as an example, the 5G terminal can slice a TR on different frequencies and divide it into channels of multiple frequencies for multiple screen projections When the device is used, since the frequencies of the channels used by each screen projection device are different, they will not interfere with each other.

可选地，若n≥m，5G终端可以从已与n个第二投屏设备连接的处于已连接投屏设备状态的5G双向通信天线中，来选择一个目标5G双向通信天线来通过频分多址技术分配给该第一投屏设备使用。Optionally, if n ≥ m, the 5G terminal can select a target 5G two-way communication antenna from the 5G two-way communication antennas in the connected screen-casting device state that have been connected to the n second screen-casting devices to pass the frequency division. The multiple access technology is allocated to the first screen projection device for use.

以图2为例，可以从4个均处于已连接投屏设备状态的TR(即TRX1、TRX2、TRX3、TRX4)中，选择一个TR来通过频分多址技术分配给该第一投屏设备使用。Taking Figure 2 as an example, from the four TRs (ie, TRX1, TRX2, TRX3, and TRX4) that are all connected to the screen-casting device, a TR can be selected to be allocated to the first screen-casting device through frequency division multiple access technology. use.

可选地，若n<m，则说明5G终端还存在未连接任何投屏设备的5G双向通信天线，因此，5G终端可以从m个5G双向通信天线中随机选择一个目标5G双向通信天线。Optionally, if n<m, it means that the 5G terminal also has a 5G bidirectional communication antenna that is not connected to any screen projection device. Therefore, the 5G terminal can randomly select a target 5G bidirectional communication antenna from m 5G bidirectional communication antennas.

可选地，在执行步骤104时，可以通过S201～S206来实现：Optionally, when step 104 is performed, S201 to S206 may be used to implement:

S201，从m个5G双向通信天线中随机选择一个目标5G双向通信天线；S201, randomly select a target 5G two-way communication antenna from m 5G two-way communication antennas;

例如，n>m，说明5G终端的m个TR(即所有的TR)均已分配给投屏设备进行连接，且每个TR至少连接了一个第二投屏设备。For example, n>m, it means that m TRs (that is, all TRs) of the 5G terminal have been allocated to the screen projection device for connection, and each TR is connected to at least one second screen projection device.

但是，对于通过一个TR来与5G终端进行投屏连接的第二投屏设备而言，该第二投屏设备通过该TR所传输数据采用的信道的载波频率是固定的，其并非会占用该TR的所有载波频率的所有信道，因此，本发明实施例的方法可以借助于不同的投屏设备虽然都通过同一个TR来与5G终端连接，但是在发送投屏内容时，通过分配该TR的不同载波频率的不同信道来与不同的投屏设备连接，从而可以实现通过该不同信道同时与多个投屏设备进行投屏内容的传输的目的。However, for the second screen projection device that is connected to the 5G terminal for screen projection through a TR, the carrier frequency of the channel used by the second screen projection device to transmit data through the TR is fixed, and it does not occupy the All channels of all carrier frequencies of the TR, therefore, the method of the embodiment of the present invention can use different screen projection devices to connect with the 5G terminal through the same TR, but when the screen projection content is sent, by assigning the TR's Different channels of different carrier frequencies are used to connect to different screen projection devices, so that the purpose of simultaneously transmitting screen projection content to multiple screen projection devices through the different channels can be achieved.

本步骤中，可以从m个TR中随机选取一个用于分配至该第一投屏设备的目标TR。In this step, one target TR to be allocated to the first screen projection device may be randomly selected from m TRs.

S202，检测所述目标5G双向通信天线的带宽；S202, detecting the bandwidth of the target 5G bidirectional communication antenna;

S203，根据所述带宽确定所述目标5G双向通信天线的信道数量P；S203, determining the number of channels P of the target 5G bidirectional communication antenna according to the bandwidth;

其中，可以根据目标TR的带宽来确定该目标TR的所有信道的总数量P，其中，P个信道的载波频率不同，即不同信道所传输的数据的频率不同。The total number P of all channels of the target TR can be determined according to the bandwidth of the target TR, wherein the carrier frequencies of the P channels are different, that is, the frequencies of data transmitted by different channels are different.

其中，P大于或等于2。其中，带宽越大，其信道数量也越多。where P is greater than or equal to 2. Among them, the greater the bandwidth, the greater the number of channels.

S204，识别P个信道中处于空闲状态的Q个信道，其中Q<P；S204, identifying Q channels in an idle state among the P channels, where Q<P;

所谓处于空闲状态的信道，即未传输任何数据的信道。The so-called idle channel is a channel that does not transmit any data.

S205，检测所述第一投屏设备所需要传输的第一数据量；S205, detecting the first amount of data that needs to be transmitted by the first screen projection device;

S206，根据所述第一数据量，从Q个信道中选取资源块数与所述第一数据量匹配的目标信道分配至所述第一投屏设备。S206, according to the first data amount, select a target channel whose number of resource blocks matches the first data amount from the Q channels and assign it to the first screen projection device.

虽然该目标TR中存在处于空闲状态的Q个信道，但是每个信道的RB(即资源块)数是存在区别的，而信道的RB数越多，该信道所能够传输的数据量就越大，因此，这里可以根据该第一投屏设备所需要传输的第一数据量的大小，来从Q个空闲信道中选取RB数可以支持传输该第一数据量的数据的目标信道，来将目标TR中的目标信道来分配给该第一投屏设备。Although there are Q channels in an idle state in the target TR, the number of RBs (ie resource blocks) of each channel is different, and the more RBs in a channel, the greater the amount of data that the channel can transmit. , therefore, according to the size of the first data amount that the first screen projection device needs to transmit, a target channel whose number of RBs can support the transmission of the first data amount can be selected from the Q idle channels to convert the target The target channel in the TR is allocated to the first screen projection device.

例如，如图4所示，检测到设备1的投屏请求，且分配目标TR(这里为TRX1)给设备1，另外，该目标TR已通过频分多址技术分配给基站、设备3、设备2来连接进行投屏，而该目标TR的目标信道的RB数可以支持设备1的数据量的传输，且目标信道处于空闲状态，因此，可以将该TRX1的目标信道分配给设备1来进行投屏，那么在5G终端与设备1通过TRX1的频率4的目标信道进行投屏的过程中，5G终端还可以与基站、设备3、设备2分别通过TRX1的频率1、频率2以及频率3的3个信道分别进行投屏。For example, as shown in Figure 4, the screen projection request ofdevice 1 is detected, and the target TR (here, TRX1) is allocated todevice 1. In addition, the target TR has been allocated to the base station, device 3, and device through frequency division multiple access technology. 2 to connect to cast the screen, and the RB number of the target channel of the target TR can support the transmission of the data volume of thedevice 1, and the target channel is in an idle state, therefore, the target channel of the TRX1 can be allocated to thedevice 1 for casting screen, then in the process of screencasting between the 5G terminal anddevice 1 through the target channel of frequency 4 of TRX1, the 5G terminal can also communicate with the base station, device 3, and device 2 throughfrequency 1, frequency 2 and 3 of frequency 3 of TRX1 respectively. Each channel is screened separately.

需要说明的是，图4中每个投屏设备占用所占用的具有相应载波频率的信道可以是固定的，也可以是可变化的(例如，并非设备1固定于在载波频率为频率4的TRX1的信道来与5G终端进行投屏数据传输)。It should be noted that the channel with the corresponding carrier frequency occupied by each screen projection device in FIG. 4 may be fixed or variable (for example, notdevice 1 is fixed on TRX1 whose carrier frequency is frequency 4). channel for screen-casting data transmission with 5G terminals).

在本发明实施例中，当通过5G双向通信天线已连接的第二投屏设备的数量n大于或等于5G双向通信天线的总数量m时，则说明5G终端的所有5G双向通信天线都已连接有投屏设备，那么为了增加同时投屏设备的数量，本发明实施例可以在一个双向通信天线的射频硬件链路的支持不同载波频率的不同信道上来传输已连接的不同投屏设备的投屏数据，从而在5G双向通信天线数量有限的情况下，增加同时投屏的投屏设备的数量。并且，提高了5G双向通信天线的频谱的利用率，同时也能更灵活的分配频谱资源，让流量大的投屏设备充分的得到更多的频谱资源。In the embodiment of the present invention, when the number n of the second screen projection devices connected through the 5G two-way communication antenna is greater than or equal to the total number m of the 5G two-way communication antenna, it means that all 5G two-way communication antennas of the 5G terminal have been connected. If there are screen-casting devices, in order to increase the number of simultaneous screen-casting devices, the embodiment of the present invention can transmit the screen-casting of the connected different screen-casting devices on different channels of the radio frequency hardware link of a bidirectional communication antenna that support different carrier frequencies Therefore, in the case of a limited number of 5G two-way communication antennas, the number of screen-casting devices that cast screens at the same time is increased. In addition, the spectrum utilization rate of the 5G bidirectional communication antenna is improved, and spectrum resources can be allocated more flexibly, so that screen projection devices with large traffic can fully obtain more spectrum resources.

可选地，在执行S205时，可以从Q个信道中随机选择一个第一信道分配至所述第一投屏设备；从分配至所述第一投屏设备的目标5G双向通信天线的第一信道处，检测与所述第一投屏设备之间传输的第一数据量；Optionally, when S205 is performed, a first channel may be randomly selected from the Q channels and allocated to the first screen projection device; from the first channel of the target 5G bidirectional communication antenna allocated to the first screen projection device At the channel, detect the first amount of data transmitted with the first screen projection device;

其中，检测第一投屏设备所需要传输的第一数据量的大小的原理与下述实施例中步骤105的详细实施例中的第二步的原理类似，这里不再赘述。The principle of detecting the size of the first data amount to be transmitted by the first screen projection device is similar to the principle of the second step in the detailed embodiment of step 105 in the following embodiments, and will not be repeated here.

那么在执行S206时，则可以根据所述第一数据量，从Q个信道中选取资源块数与所述第一数据量匹配的目标信道；当所述目标信道与所述第一信道不同时，则将分配至所述第一投屏设备的信道从所述第一信道切换至所述目标信道。Then when S206 is performed, a target channel whose number of resource blocks matches the first data amount may be selected from the Q channels according to the first data amount; when the target channel is different from the first channel , the channel allocated to the first screen projection device is switched from the first channel to the target channel.

其中，由于从剩余处于空闲状态的Q个信道中选择一个第一信道分配给第一投屏设备的原因在于，可以获取该第一投屏设备所需要传输的第一数据量的大小，但是，该第一信道的RB数不一定可以支持传输该第一数据量的数据，因此，可以根据该第一数据量，来从Q个信道中选取RB数支持传输该第一数据量的数据的目标信道，那么当该第一信道和目标信道不同时，则将分配至所述第一投屏设备的信道从所述第一信道切换至所述目标信道。那么如果该第一信道和目标信道相同，则不需要执行上述切换步骤。Among them, the reason for selecting a first channel from the remaining Q channels in an idle state and assigning it to the first screen projection device is that the size of the first data amount that the first screen projection device needs to transmit can be obtained, but, The number of RBs of the first channel may not necessarily support the transmission of the data of the first amount of data. Therefore, the number of RBs may be selected from the Q channels according to the first amount of data to support the target of transmitting the data of the first amount of data. channel, then when the first channel and the target channel are different, the channel allocated to the first screen projection device is switched from the first channel to the target channel. Then, if the first channel and the target channel are the same, the above switching step does not need to be performed.

在本发明实施例中，可以通过首先从Q个信道中随机分配一个第一信道给第一投屏设备的方式，来获取该第一投屏设备所传输的数据量大小，从而可以准确的根据该第一投屏设备所需要传输的该数据量大小，来合理分配适应与该数据量大小的目标信道，提升5G终端与第一投屏设备之间的数据传输速度。且能更灵活的分配频谱资源，让流量大的投屏设备充分的得到更多的频谱资源。In this embodiment of the present invention, the amount of data transmitted by the first screen projection device can be obtained by randomly allocating a first channel from the Q channels to the first screen projection device, so that the amount of data transmitted by the first screen projection device can be accurately The size of the amount of data that the first screen projection device needs to transmit is used to reasonably allocate a target channel adapted to the size of the data amount, so as to improve the data transmission speed between the 5G terminal and the first screen projection device. And it can allocate spectrum resources more flexibly, so that screen projection devices with large traffic can fully obtain more spectrum resources.

在上述实施例中，当所述第一投屏设备的数量为多个时，也就是说，当同时检测到多个第一投屏设备的5G投屏请求时，则在执行所述根据所述第一数据量，从Q个信道中选取资源块数与所述第一数据量匹配的目标信道分配至所述第一投屏设备的步骤时，可以通过以下方式来实现：In the above embodiment, when the number of the first screen projection devices is multiple, that is, when 5G screen projection requests from multiple first screen projection devices are detected at the same time, the The first data amount, when selecting a target channel whose number of resource blocks matches the first data amount from the Q channels and assigning it to the first screen projection device, can be achieved in the following ways:

获取多个第一投屏设备对应的多个第一数据量的比例关系；从Q个信道中选取多个资源块数的比例成所述比例关系的多个目标信道；将所述多个目标信道分配至对应的所述多个第一投屏设备。Obtain the proportional relationship of the multiple first data amounts corresponding to the multiple first screen projection devices; select multiple target channels whose proportions of the number of resource blocks are in the proportional relationship from the Q channels; Channels are allocated to the corresponding plurality of first screen projection devices.

具体而言，例如多个第一投屏设备分别为设备1、设备2和设备3，它们三个设备所需要的数据量大小的比例关系为设备1对应的第一数据量:设备2对应的第一数据:设备3对应的第一数据量＝1:2:3。而Q个空闲的信道中每个信道的RB数是已知的，因此，可以也获取RB数成1:2:3的目标信道1、目标信道2以及目标信道3，并将目标信道1、目标信道2以及目标信道3依次分配给设备1、设备2以及设备3。Specifically, for example, the multiple first screen projection devices aredevice 1, device 2, and device 3, respectively, and the proportional relationship between the data volumes required by the three devices is the first data volume corresponding to device 1: the first data volume corresponding to device 2 First data: the first data amount corresponding to device 3=1:2:3. The number of RBs for each channel in the Q idle channels is known. Therefore,target channel 1, target channel 2 and target channel 3 with RB numbers of 1:2:3 can also be obtained, andtarget channel 1, target channel 2 and target channel 3 can be obtained. Target channel 2 and target channel 3 are assigned todevice 1, device 2, and device 3 in sequence.

其中，目标信道1、目标信道2以及目标信道3的RB数也是分别与设备1的第一数据量、设备2的第一数据量、设备3的第一数据量相匹配的，即相应信道的RB数支持相应设备的第一数据量的数据传输。The RB numbers oftarget channel 1, target channel 2, and target channel 3 also match the first data volume ofdevice 1, the first data volume of device 2, and the first data volume of device 3, respectively, that is, the The number of RBs supports data transmission of the first data amount of the corresponding device.

在本发明实施例中，当检测到多个第一投屏设备的投屏请求，则可以按照多个第一投屏设备所需要的第一数据量之间的比例关系，来分配RB数成该比例关系的多个目标信道给给多个第一投屏设备，从而能够快速的对多个投屏设备分配信道，提升多个投屏设备投屏连接的效率。In this embodiment of the present invention, when screen projection requests from multiple first screen projection devices are detected, the number of RBs may be allocated according to the proportional relationship between the first data amounts required by the multiple first screen projection devices. The multiple target channels in the proportional relationship are assigned to the multiple first screen projection devices, so that channels can be quickly allocated to the multiple screen projection devices, and the efficiency of the screen projection connection of the multiple screen projection devices can be improved.

可选地，当第一投屏设备为基站时，即终端与基站进行频分多址的通信时，则可以由基站来分配通过该基站来与5G终端进行投屏连接的多个投屏设备，所需要使用的目标信道；而当第一投屏设备为终端时，则由5G终端来对每个第一投屏设备分配目标信道。Optionally, when the first screen projection device is a base station, that is, when the terminal communicates with the base station in frequency division multiple access, the base station can allocate multiple screen projection devices that are connected to the 5G terminal for screen projection through the base station. , the target channel to be used; and when the first screen projection device is a terminal, the 5G terminal allocates the target channel to each first screen projection device.

步骤105，检测所述第一投屏设备以及每个第二投屏设备所需要传输的数据量，根据所述数据量，对所述第一投屏设备分配目标5G双向通信天线；Step 105: Detect the amount of data that the first screen projection device and each second screen projection device need to transmit, and allocate a target 5G two-way communication antenna to the first screen projection device according to the data amount;

其中，当n<m时，说明5G终端还存在处于未连接任何设备的状态的TR，因此，转到执行步骤105，来根据当前请求连接的投屏设备以及所有已连接的投屏设备所分别需要传输的数据量大小，来灵活的对当前请求进行投屏的第一投屏设备分别相应的TR。Among them, when n<m, it means that the 5G terminal still has a TR in a state that is not connected to any device. Therefore, go to step 105 to perform the screencasting device currently requested to be connected and all connected screencasting devices respectively. The size of the amount of data to be transmitted is used to flexibly project the corresponding TR of the first screen projection device currently requesting to perform screen projection.

可选地，在执行步骤105时，可以通过以下流程来实现：Optionally, when step 105 is executed, the following process may be used to implement:

第一步，从m-n个处于未连接投屏设备状态的5G双向通信天线中随机选择一个5G双向通信天线分配至所述第一投屏设备；The first step is to randomly select a 5G two-way communication antenna from m-n 5G two-way communication antennas that are not connected to the screen-casting device and assign it to the first screen-casting device;

首先，从剩余未连接投屏设备的TR中选择一个TR分配给第一投屏设备的原因在于，可以获取该第一投屏设备所需要传输的第一数据量。First of all, the reason for selecting a TR from the remaining TRs that are not connected to the screen-casting device and assign it to the first screen-casting device is to obtain the first amount of data that the first screen-casting device needs to transmit.

第二步，从分配至所述第一投屏设备的5G双向通信天线处，检测与所述第一投屏设备之间传输的第一数据量；The second step is to detect the first amount of data transmitted with the first screen projection device from the 5G bidirectional communication antenna allocated to the first screen projection device;

需要说明的是，当第一投屏设备为基站时，且该5G投屏请求为5G终端向基站发送的，用于同时向设备4～设备w进行投屏，则该第一数据量为5G终端向该基站发送的数据量；It should be noted that when the first screen projection device is the base station, and the 5G screen projection request is sent by the 5G terminal to the base station for simultaneously projecting the screen to devices 4 to w, the first data amount is 5G The amount of data sent by the terminal to the base station;

当第一投屏设备为基站时，且该5G投屏请求为基站向5G终端发送的，用于设备4～设备w向5G终端进行投屏，则该第一数据量为设备4～设备w通过基站向5G终端发送的数据量之和。When the first screen projection device is a base station, and the 5G screen projection request is sent by the base station to the 5G terminal for device 4 to device w to perform screen projection to the 5G terminal, the first data volume is device 4 to device w The sum of the amount of data sent by the base station to the 5G terminal.

由于5G终端已经通过一个TR来与第一投屏设备连接，因此，可以从该TR处检测到二者之间传输的第一数据量大小。Since the 5G terminal has been connected to the first screen projection device through a TR, the size of the first amount of data transmitted between the two can be detected from the TR.

第三步，从与每个所述第二投屏设备连接的每个5G双向通信天线处，检测与每个所述第二投屏设备之间传输的每个第二数据量；In the third step, from each 5G bidirectional communication antenna connected to each of the second screen projection devices, detect the amount of each second data transmitted with each of the second screen projection devices;

其中，由于在检测到上述5G投屏请求之前，5G终端已经通过至少一个TR来与至少一个第二投屏设备连接，因此，检测每个第二投屏设备所需要传输的数据量大小的方案类似于第二步，也是从相应的TR处检测数据量。Among them, since the 5G terminal has been connected to at least one second screen projection device through at least one TR before the above-mentioned 5G screen projection request is detected, the solution for detecting the amount of data that each second screen projection device needs to transmit Similar to the second step, the amount of data is also detected from the corresponding TR.

第四步，识别所述第一数据量和n个所述第二数据量中的最大数据量所对应的目标投屏设备；The fourth step is to identify the target screen projection device corresponding to the largest data amount in the first data amount and the n second data amounts;

其中，可以将第二步和第三步得到的n+1个数据量作从大到小的排序，从而识别到需要最大数据量的目标投屏设备，其中，所述目标投屏设备为所述第一投屏设备，或n个所述第二投屏设备中的一个。Among them, the n+1 data volumes obtained in the second and third steps can be sorted from large to small, so as to identify the target screen projection device that requires the largest amount of data, wherein the target screen projection device is all The first screen projection device, or one of the n second screen projection devices.

第五步，将m-n-1个处于未连接投屏设备状态的5G双向通信天线分配至所述目标投屏设备，其中，分配至所述第一投屏设备的5G双向通信天线为目标5G双向通信天线。Step 5: Allocate m-n-1 5G two-way communication antennas that are not connected to the screen-casting device to the target screen-casting device, wherein the 5G two-way communication antenna allocated to the first screen-casting device is the target 5G two-way communication antenna communication antenna.

其中，由于目前存在n+1个投屏设备占用了n+1个TR，因此，目前剩余的TR数量为m-n-1，可以将剩余的m-n-1个处于未连接投屏设备状态的TR均分配至该目标投屏设备。Among them, since there are currently n+1 screen projection devices occupying n+1 TRs, the number of remaining TRs is m-n-1, and the remaining m-n-1 TRs in the state of not connected to the screen projection device can be all Assign to the target screencasting device.

那么当该目标投屏设备为该第一投屏设备时，则分配至该第一投屏设备的目标5G双向通信天线则可以包括上述第一步中随机分配的一个TR以及第五步中分配的m-n-1个TR；而当该目标投屏设备不为该第一投屏设备，而是n个第二投屏设备中的一个时，则该目标5G双向通信天线则是上述第一步中随机分配给第一投屏设备的一个TR。Then, when the target screen projection device is the first screen projection device, the target 5G bidirectional communication antenna allocated to the first screen projection device may include a TR randomly allocated in the first step and a TR allocated in the fifth step. m-n-1 TRs; and when the target screen projection device is not the first screen projection device, but one of n second screen projection devices, the target 5G two-way communication antenna is the first step above A TR randomly assigned to the first screen projection device.

可选地，当目标5G双向通信天线所支持传输的数据量之和仍旧小于该目标投屏设备所需要的数据量时，则可以将单向通信天线也分配给该目标投屏设备，例如图2中的4个DR。Optionally, when the sum of the data volume supported by the target 5G two-way communication antenna is still less than the data volume required by the target screen projection device, the one-way communication antenna can also be allocated to the target screen projection device, for example, as shown in Fig. 4 DRs out of 2.

在本发明实施例中，在对新接入的一个投屏设备分配双向通信天线时，可以根据所有已连接的投屏设备(包括该新接入的投屏设备)所需的数据量大小关系进行智能分配，将未连接任何投屏设备的剩余的双向通信天线来分配给需要流量最大的投屏设备(当然，该投屏设备也可以是基站)，以提高投屏数据的传输速率。In this embodiment of the present invention, when allocating a two-way communication antenna to a newly-connected screen-casting device, the relationship between the amount of data required by all the connected screen-casting devices (including the newly-connected screen-casting device) can be determined Perform intelligent allocation, and allocate the remaining two-way communication antennas that are not connected to any screencasting device to the screencasting device that requires the most traffic (of course, the screencasting device can also be a base station) to improve the transmission rate of screencasting data.

步骤106，利用所述目标5G双向通信天线，与所述第一投屏设备传输投屏数据。Step 106 , using the target 5G bidirectional communication antenna to transmit screen projection data with the first screen projection device.

其中，对第一投屏设备分配了目标5G双向通信天线进行连接，从而进行5G终端与第一投屏设备之间的投屏数据的传输；而5G终端还通过其他的双向通信天线来与n个第二投屏设备连接，从而使得5G终端通过其他的双向通信天线来与n个第二投屏设备之间进行投屏数据的传输，从而利用5G的双向通信天线，实现了5G终端与多个设备之间的同时投屏。Among them, the target 5G two-way communication antenna is allocated to the first screen projection device for connection, so as to transmit screen projection data between the 5G terminal and the first screen projection device; and the 5G terminal also communicates with n through other two-way communication antennas.
