用于无线通信的电子设备和方法、计算机可读存储介质Electronic device and method for wireless communication, computer readable storage medium
本申请要求于2021年3月12日提交中国专利局、申请号为202110270987.9、发明名称为“用于无线通信的电子设备和方法、计算机可读存储介质”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。This application claims the priority of the Chinese patent application filed on March 12, 2021 with the application number 202110270987.9 and the invention title "Electronic device and method for wireless communication, computer-readable storage medium", all of which are The contents are incorporated herein by reference.
技术领域technical field
本公开涉及无线通信技术领域,具体地涉及基站向用户设备指示有关定时提前量的信息。更具体地,涉及一种用于无线通信的电子设备和方法、计算机可读存储介质。The present disclosure relates to the technical field of wireless communication, and in particular, to a base station indicating information about a timing advance to a user equipment. More specifically, it relates to an electronic device and method for wireless communication, and a computer-readable storage medium.
背景技术Background technique
在无线通信环境中,定时提前量(TA,Timing advance)一般用于用户设备上行传输,指为了将用户设备的上行传输包在希望的时间到达基站,预估由于距离引起的射频传输时延,提前相应时间发出数据包。In the wireless communication environment, timing advance (TA, Timing advance) is generally used for uplink transmission of user equipment, which means to estimate the radio frequency transmission delay caused by distance in order to make the uplink transmission packet of user equipment arrive at the base station at the desired time. The packets are sent out in advance of the corresponding time.
TA错误会引起基站处产生符号间干扰(ISI,inter-symbol-interfering)。图1是示出现有技术中的、由于定时提前量而导致符号间干扰的示意图。如图1所示,有四个用户设备UE#0、UE#1、UE#2和UE#3。对于UE#0而言,基站接收机的接收窗口(例如,傅立叶变换(FFT)的窗口)的起点正好落在从UE#0接收到的符号的CP(循环前缀)内时,因此不会引起ISI干扰,基站能够正确解码期望的信号。而对于UE#1而言,由于UE#1从基站接收到的TA与其实际需要的TA之间存在较大差异(即存在TA错误),基站接收机的接收窗口的起点落在从UE#1接收到的符号的CP之外,因此会引起ISI干扰,基站可能不能正确解码期望的信号。类似地,基站从UE#2和UE#3接收到的符号也会引起ISI干扰。当ISI大到一定程度会导致解码错误,导致解码失败,降低用户设备的传输效率,影响用户体验。TA errors may cause inter-symbol-interfering (ISI, inter-symbol-interfering) at the base station. FIG. 1 is a schematic diagram illustrating inter-symbol interference due to timing advance in the prior art. As shown in Figure 1, there are four user equipments UE#0, UE#1, UE#2 and UE#3. For UE#0, the starting point of the base station receiver's receive window (eg, the Fourier Transform (FFT) window) falls exactly within the CP (Cyclic Prefix) of the symbols received from UE#0, and therefore does not cause ISI interference, the base station can correctly decode the desired signal. For UE#1, since there is a large difference between the TA received by UE#1 from the base station and the TA it actually needs (that is, there is a TA error), the starting point of the receiving window of the base station receiver falls on the base station from UE#1. The received symbols are outside the CP, thus causing ISI interference and the base station may not be able to correctly decode the desired signal. Similarly, the symbols received by the base station from UE#2 and UE#3 also cause ISI interference. When the ISI is too large to a certain extent, it will cause decoding errors, resulting in decoding failures, reducing the transmission efficiency of the user equipment, and affecting the user experience.
TA变化越快,越容易产生TA错误。因此,在TA快速变化的场景(例如,由于基站的移动导致基站与UE之间的相对位置不断变化,从而 导致TA的变化非常频繁的场景。又例如,在高铁,飞机等UE快速移动场景中,由于UE的移动导致基站与UE之间的相对位置不断变化,从而导致TA的变化非常频繁的场景)中,基站如何向用户设备指示TA成为亟待解决的问题。The faster the TA changes, the easier it is to generate TA errors. Therefore, in the scene where the TA changes rapidly (for example, the relative position between the base station and the UE is constantly changing due to the movement of the base station, which leads to the scene where the TA changes very frequently. For another example, in the high-speed rail, airplane and other fast UE moving scenarios , due to the movement of the UE, the relative position between the base station and the UE is constantly changing, resulting in a scenario where the TA changes very frequently), how the base station indicates the TA to the user equipment becomes an urgent problem to be solved.

图2示出了根据本公开的一个实施例的用于无线通信的电子设备的功能模块框图。FIG. 2 shows a functional block diagram of an electronic device for wireless communication according to an embodiment of the present disclosure.
如图2所示,电子设备200包括:预配置单元201,其可以预先配置设置信息,其中,设置信息指示是否要向电子设备200服务范围内的用户设备动态地发送有关用户设备的定时提前量的信息;以及控制单元203,其可以基于设置信息控制用户设备的上行传输。As shown in FIG. 2, the electronic device 200 includes: a pre-configuration unit 201, which can pre-configure setting information, wherein the setting information indicates whether to dynamically send the timing advance of the user equipment to the user equipment within the service range of the electronic device 200 and the control unit 203, which can control the uplink transmission of the user equipment based on the setting information.
其中,预配置单元201和控制单元203可以由一个或多个处理电路实现,该处理电路例如可以实现为芯片。The pre-configuration unit 201 and the control unit 203 may be implemented by one or more processing circuits, and the processing circuits may be implemented as chips, for example.
电子设备200可以作为无线通信系统中的网络侧设备,具体地例如可以设置在基站侧或者可通信地连接到基站。这里,还应指出,电子设备200可以以芯片级来实现,或者也可以以设备级来实现。例如,电子设备200可以工作为基站本身,并且还可以包括诸如存储器、收发器(未示出)等外部设备。存储器可以用于存储基站实现各种功能需要执行的程序和相关数据信息。收发器可以包括一个或多个通信接口以支持与不同设备(例如,用户设备、其他基站等等)间的通信,这里不具体限制收发器的实现形式。The electronic device 200 can be used as a network-side device in a wireless communication system, and specifically, for example, can be set on the base station side or communicably connected to the base station. Here, it should also be pointed out that the electronic device 200 may be implemented at the chip level, or may also be implemented at the device level. For example, the electronic device 200 may function as the base station itself, and may also include external devices such as memory, transceivers (not shown). The memory can be used to store programs and related data information that the base station needs to execute to implement various functions. The transceiver may include one or more communication interfaces to support communication with different devices (eg, user equipment, other base stations, etc.), and the implementation form of the transceiver is not particularly limited here.
根据本公开的无线通信系统可以是5G NR(New Radio,新无线)通信系统。进一步,根据本公开的无线通信系统可以包括非地面网络(Non-terrestrial network,NTN)。可选地,根据本公开的无线通信系统 还可以包括地面网络(Terrestrial network,TN)。另外,本领域技术人员可以理解,根据本公开的无线通信系统还可以是4G或3G通信系统。The wireless communication system according to the present disclosure may be a 5G NR (New Radio) communication system. Further, the wireless communication system according to the present disclosure may include a non-terrestrial network (NTN). Optionally, the wireless communication system according to the present disclosure may further include a terrestrial network (TN). In addition, those skilled in the art can understand that the wireless communication system according to the present disclosure may also be a 4G or 3G communication system.
作为示例,在电子设备200为低轨卫星的情况下,由于低轨卫星的移动速度较快,TA变化越快,因此可以通过设置信息指示要向用户设备发送有关用户设备的定时提前量的信息,而在电子设备200为同步卫星的情况下,由于同步卫星的移动速度较慢,TA变化越慢,因此可以通过设置信息指示不向用户设备发送有关用户设备的定时提前量的信息。作为另一示例,在地面网络通信的情况下,如果用户设备(例如,车载设备)移动速度较高,则TA变化较快,电子设备200可以通过设置信息指示要向用户设备发送有关用户设备的定时提前量的信息,而如果用户设备移动速度较低,则TA变化较慢,电子设备200可以通过设置信息指示不向用户设备发送有关用户设备的定时提前量的信息。由此可见,根据本实施例的电子设备200可以根据设置信息动态地向用户设备指示有关用户设备的定时提前量的信息。As an example, in the case where the electronic device 200 is a low-orbit satellite, since the low-orbit satellite moves faster, the TA changes faster. Therefore, the setting information can be used to indicate that information about the timing advance of the user equipment is to be sent to the user equipment. However, when the electronic device 200 is a geostationary satellite, since the moving speed of the geostationary satellite is slower, the TA changes more slowly, so the setting information can be used to indicate that the information about the timing advance of the user equipment is not sent to the user equipment. As another example, in the case of terrestrial network communication, if the user equipment (eg, in-vehicle equipment) moves at a relatively high speed, the TA changes rapidly, and the electronic device 200 may indicate through the setting information to send information about the user equipment to the user equipment. If the user equipment moves at a low speed, the TA changes slowly, and the electronic device 200 may indicate through the setting information not to send the information about the timing advance of the user equipment to the user equipment. It can be seen that the electronic device 200 according to this embodiment can dynamically indicate to the user equipment information about the timing advance of the user equipment according to the setting information.
在现有技术中,基站不会预先配置有关定时提前量的设置信息。然而,根据本公开实施例的电子设备200能够预先配置有关定时提前量的设置信息,并且能够基于设置信息控制用户设备的上行传输。In the prior art, the base station does not pre-configure the setting information about the timing advance. However, the electronic device 200 according to the embodiment of the present disclosure can pre-configure the setting information about the timing advance, and can control the uplink transmission of the user equipment based on the setting information.
作为示例,预配置单元201可以被配置为通过无线资源控制(RRC)信令承载设置信息。例如,预配置单元201可以配置新的RRC参数如DynamicTACommond来承载上述设置信息。本领域技术人员应该理解,除了RRC信令之外,还存在承载设置信息的其他信令,这里不再累述。As an example, the pre-configuration unit 201 may be configured to carry the setting information through Radio Resource Control (RRC) signaling. For example, the pre-configuration unit 201 may configure new RRC parameters such as DynamicTACommond to carry the above-mentioned setting information. Those skilled in the art should understand that, in addition to the RRC signaling, there are other signaling carrying the setting information, which will not be described here.
作为示例,控制单元203可以被配置为在设置信息为有效的情况下向用户设备发送有关定时提前量的信息,以便于用户设备动态地更新定时提前量并基于更新后的定时提前量进行上行传输。例如,在上述参数DynamicTACommond为enabled时,控制单元203向用户设备发送有关定时提前量的信息,以便于用户设备动态地更新其定时提前量;在上述参数DynamicTACommond为disabled时,控制单元203不向用户设备发送有关定时提前量的信息。As an example, the control unit 203 may be configured to send information about the timing advance to the user equipment when the setting information is valid, so that the user equipment can dynamically update the timing advance and perform uplink transmission based on the updated timing advance . For example, when the above parameter DynamicTACommond is enabled, the control unit 203 sends information about the timing advance to the user equipment, so that the user equipment can dynamically update its timing advance; when the above parameter DynamicTACommond is disabled, the control unit 203 does not send the information to the user. The device sends information about the timing advance.
下文中先描述电子设备200如何快速及时地向用户设备发送有关定时提前量的信息以便于用户设备动态地更新定时提前量。The following first describes how the electronic device 200 sends information about the timing advance to the user equipment quickly and timely, so that the user equipment can dynamically update the timing advance.
作为示例,控制单元203可以被配置为通过用于上行调度的下行链 路控制信息(DCI)信令来发送有关定时提前量的信息。本领域技术人员应该理解,除了DCI信令之外,还存在用于快速及时地发送有关定时提前量的信息的其他信令,这里不再累述。As an example, the control unit 203 may be configured to send the information on the timing advance through Downlink Control Information (DCI) signaling for uplink scheduling. Those skilled in the art should understand that, in addition to the DCI signaling, there are other signaling for quickly and timely sending the information about the timing advance, which will not be described here.
在现有技术中,基站通过媒体接入控制控制元素(MAC CE)以定时提前组(TAG)级对每个用户设备进行TA更新,MAC CE包含在物理下行共享信道(PDSCH)中进行发送,PDSCH需要混合自动重传请求确认(HARQ-ACK)反馈,而上行调度承载在DCI中进行发送,因此即使在发完TA指令后的下一个时隙就进行上行调度,当往返延迟(RTD)较大时,也会带来TA失效的问题。尤其在TA快速变化的场景中,MAC CE的通知可能不够及时,会造成用户调度的更大时延从而引起更严重的ISI,降低用户的传输效率,从而降低用户体验。In the prior art, the base station performs TA update for each user equipment at the timing advance group (TAG) level through the medium access control control element (MAC CE), and the MAC CE is included in the physical downlink shared channel (PDSCH) for transmission, PDSCH needs hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback, and uplink scheduling is carried in DCI for transmission, so even if the uplink scheduling is performed in the next time slot after the TA command is sent, when the round-trip delay (RTD) is longer When it is large, it will also bring about the problem of TA failure. Especially in the scenario where the TA changes rapidly, the notification of MAC CE may not be timely enough, which will cause a greater delay in user scheduling and cause more serious ISI, reduce the transmission efficiency of the user, and thus reduce the user experience.
为了方便比较,图3示出了现有技术中的、基站通过媒体接入控制控制元素向用户设备发送有关定时提前量的信息的信息交互图,而图4示出了根据本公开实施例的、电子设备200通过下行链路控制信息向用户设备发送有关定时提前量的信息的信息交互图。For the convenience of comparison, FIG. 3 shows the information interaction diagram in the prior art in which the base station sends the information about the timing advance to the user equipment through the medium access control control element, and FIG. 4 shows the information interaction diagram according to the embodiment of the present disclosure. , an information interaction diagram in which the electronic device 200 sends the information about the timing advance to the user equipment through the downlink control information.
先描述图3中涉及的信息交互。在S30中,基站接收来自用户设备的调度请求;在S31中,基站通过DCI告知用户设备发送缓冲状态报告(BSR);在S32中,基站接收来自用户设备的BSR;在S33中,基站通过物理下行控制信道(PDCCH)和PDSCH向用户设备发送有关定时提前量的信息(如上面提及的,MAC CE包含在PDSCH中进行发送);在S34中,基站接收来自用户设备的确认(ACK);在S35中,基站通过DCI告知用户设备传送数据;在S36中,基站接收来自用户设备的上行数据传输。The information interaction involved in Figure 3 is first described. In S30, the base station receives the scheduling request from the user equipment; in S31, the base station informs the user equipment to send a buffer status report (BSR) through DCI; in S32, the base station receives the BSR from the user equipment; The downlink control channel (PDCCH) and PDSCH send information about the timing advance to the user equipment (as mentioned above, the MAC CE is included in the PDSCH for transmission); in S34, the base station receives an acknowledgment (ACK) from the user equipment; In S35, the base station informs the user equipment to transmit data through DCI; in S36, the base station receives uplink data transmission from the user equipment.
接下来描述图4中涉及的信息交互。在S40中,电子设备200接收来自用户设备的调度请求;在S41中,电子设备200通过DCI告知用户设备发送BSR;在S42中,电子设备200接收来自用户设备的BSR;在S43中,基站通过DCI向用户设备发送有关定时提前量的信息并告知用户设备传送数据;在S44中,基站接收来自用户设备的上行数据传输。Next, the information interaction involved in FIG. 4 is described. In S40, the electronic device 200 receives the scheduling request from the user equipment; in S41, the electronic device 200 informs the user equipment to send the BSR through DCI; in S42, the electronic device 200 receives the BSR from the user equipment; in S43, the base station passes The DCI sends information about the timing advance to the user equipment and informs the user equipment to transmit data; in S44, the base station receives the uplink data transmission from the user equipment.
由以上描述可知,根据本公开实施例的电子设备200可以通过DCI信令动态地向用户设备发送有关定时提前量的信息,使得用户设备能够快速并及时地更新其有关定时提前量的信息,从而提高用户设备的数据 吞吐量,降低用户设备数据传输时延并改善用户体验。It can be seen from the above description that the electronic device 200 according to the embodiment of the present disclosure can dynamically send information about the timing advance to the user equipment through DCI signaling, so that the user equipment can quickly and timely update its information about the timing advance, thereby Improve the data throughput of the user equipment, reduce the data transmission delay of the user equipment, and improve the user experience.
作为示例,有关定时提前量的信息可以包括电子设备200所确定的、用户设备的当前定时提前量与用户设备的前一次定时提前量之间的差值。例如,假设电子设备200确定用户设备的当前定时提前量为TA_new,并且电子设备200计算当前定时提前量TA_new与用户设备的前一次定时提前量TA_old之间的差值为TA_DCI,则电子设备200将TA_DCI作为有关定时提前量的信息发送给用户设备。用户设备基于其前一次定时提前量TA_old和所接收到的TA_DCI,计算出其当前定时提前量TA_new=TA_old+TA_DCI,并采用TA_new值来进行当前的上行传输。As an example, the information about the timing advance may include a difference between the current timing advance of the user equipment and the previous timing advance of the user equipment determined by the electronic device 200 . For example, assuming that the electronic device 200 determines that the current timing advance of the user equipment is TA_new, and the electronic device 200 calculates that the difference between the current timing advance TA_new and the previous timing advance TA_old of the user equipment is TA_DCI, the electronic device 200 will TA_DCI is sent to the user equipment as information about the timing advance. The user equipment calculates its current timing advance TA_new=TA_old+TA_DCI based on its previous timing advance TA_old and the received TA_DCI, and uses the TA_new value for current uplink transmission.
作为示例,有关定时提前量的信息可以包括电子设备200所确定的、用户设备的当前定时提前量与用户设备的前一次定时提前量之间的与时间有关的偏移值。例如,假设电子设备200所确定的与时间有关的偏移值为TA_drift,则电子设备200将TA_drift作为有关定时提前量的信息发送给用户设备。用户设备基于其前一次定时提前量TA_old和所接收到的TA_drift,计算出其当前定时提前量TA_new=TA_old+Time*TA_drift(其中,Time表示时间间隔),则用户设备采用TA_new值来进行当前的上行传输。As an example, the information about the timing advance may include a time-related offset value determined by the electronic device 200 between the current timing advance of the user equipment and the previous timing advance of the user equipment. For example, assuming that the time-related offset value determined by the electronic device 200 is TA_drift, the electronic device 200 sends TA_drift as the information about the timing advance to the user equipment. The user equipment calculates its current timing advance TA_new=TA_old+Time*TA_drift based on its previous timing advance TA_old and the received TA_drift (where Time represents the time interval), then the user equipment uses the TA_new value to perform the current timing advance. upstream transmission.
上面提及的前一次定时提前量TA_old的值是针对某个TAG或者某个小区或者某个波束的值,该值可以是电子设备200通过MAC CE而通知/更新的,也可以是通过DCI而通知/更新的。The value of the previous timing advance TA_old mentioned above is the value for a certain TAG or a certain cell or a certain beam. notified/updated.
作为示例,有关定时提前量的信息可以包括电子设备200所确定的、用户设备的当前定时提前量。例如,假设电子设备200所确定的当前定时提前量为TA_new,则电子设备200将TA_new发送给用户设备。用户设备采用TA_new值来进行当前的上行传输。As an example, the information on the timing advance may include the current timing advance of the user equipment determined by the electronic device 200 . For example, assuming that the current timing advance determined by the electronic device 200 is TA_new, the electronic device 200 sends TA_new to the user equipment. The user equipment uses the TA_new value for current uplink transmission.
作为示例,有关定时提前量的信息还包括与定时提前量相关的定时提前组TAG和/或小区的ID。例如,TAG的ID可以指示TA值是针对哪个TAG的,一个TAG中可以包含一个或者多个小区的ID。当TA是以小区为单位而进行通知/更新的情况下,可以将TAG的ID替换成小区的ID。以上述方式,电子设备200可以显式地向用户设备通知与定时提前量相关的定时提前组TAG和/或小区的ID。As an example, the information on the timing advance also includes the timing advance group TAG and/or the ID of the cell related to the timing advance. For example, the ID of the TAG may indicate which TAG the TA value is for, and one TAG may contain the IDs of one or more cells. When the TA is notified/updated in units of cells, the ID of the TAG may be replaced with the ID of the cell. In the above manner, the electronic device 200 can explicitly notify the user equipment of the timing advance group TAG and/or the ID of the cell related to the timing advance.
为了降低承载有关定时提前量的信息的信令的开销,该信令中可以 不显式地指明有关定时提前量的信息是针对哪个TAG和/或小区的。In order to reduce the overhead of signaling carrying the information about the timing advance, the signaling may not explicitly indicate which TAG and/or cell the information about the timing advance is for.
作为示例,控制单元203可以被配置为通过承载有关定时提前量的信息的信令中的有关定时提前组和/或小区的信息,来指示与定时提前量相关的定时提前组和/或小区的ID。如上所述,承载有关定时提前量的信息的信令例如可以是DCI。例如,可以通过DCI信令中所调度的时频资源块所在的TAG信息和/或小区信息来隐式地向用户设备通知有关定时提前量的信息是针对哪个TAG和/或小区的。As an example, the control unit 203 may be configured to indicate the information about the timing advance group and/or cell related to the timing advance through the information about the timing advance group and/or cell in the signaling carrying the information about the timing advance ID. As mentioned above, the signaling carrying the information about the timing advance may be, for example, DCI. For example, the user equipment may be implicitly notified of which TAG and/or cell the information about the timing advance is for through the TAG information and/or cell information where the scheduled time-frequency resource blocks are located in the DCI signaling.
此外,作为示例,控制单元203可以被配置为通过承载有关定时提前量的信息的信令中的有关波束的信息,来指示与定时提前量相关的波束的ID。例如,可以通过DCI信令中所指示的波束ID(如传输配置指示(TCI)、SRS资源指示(SRI)等)来隐式地向用户设备通知有关定时提前量的信息是针对哪个波束的。Furthermore, as an example, the control unit 203 may be configured to indicate the ID of the beam related to the timing advance through the information on the beam in the signaling carrying the information on the timing advance. For example, the user equipment may be implicitly informed of which beam the timing advance information is for through the beam ID indicated in the DCI signaling (eg, Transmission Configuration Indication (TCI), SRS Resource Indication (SRI), etc.).
接下来描述电子设备200如何基于用户设备的定时提前量来对用户设备进行调度。Next, it is described how the electronic device 200 schedules the user equipment based on the timing advance of the user equipment.
图5是示出根据本公开实施例的电子设备200的移动和用户设备的分布的场景的示例的图。FIG. 5 is a diagram illustrating an example of a scenario of movement of the electronic device 200 and distribution of user devices according to an embodiment of the present disclosure.
如图5所示,包括四个用户设备UE#1-UE#4,电子设备200在图5中被示出为卫星。例如,在T1’时刻,UE#2位于卫星的正下方(卫星波束与UE#2的夹角为90°),UE#1和UE#3与卫星波束的夹角例如分别为100°和80°,处于卫星小区/波束边缘的UE#4与卫星波束的夹角例如为70°。卫星朝着远离UE#3和UE#4的方向移动。本领域技术人员可以理解,图5的场景仅是示例而非限制性的,下文中的描述不仅限于图5所示出的场景。As shown in FIG. 5, including four user equipments UE#1-UE#4, the electronic device 200 is shown in FIG. 5 as a satellite. For example, at time T1', UE#2 is located directly below the satellite (the included angle between the satellite beam and UE#2 is 90°), and the included angles between UE#1 and UE#3 and the satellite beam are, for example, 100° and 80°, respectively. °, the included angle between UE#4 at the edge of the satellite cell/beam and the satellite beam is, for example, 70°. The satellite is moving away from UE#3 and UE#4. Those skilled in the art can understand that the scenario in FIG. 5 is only an example and not a limitation, and the following description is not limited to the scenario shown in FIG. 5 .
卫星在此时以卫星波束中心垂直映射到地面上的点为参考点,向上述四个用户设备发送有关定时提前量的信息(例如,包括用户设备的当前定时提前量、用户设备的当前定时提前量与用户设备的前一次定时提前量之间的差值、用户设备的当前定时提前量与用户设备的前一次定时提前量之间的与时间有关的偏移值中至少之一),通常情况下,由于上述四个用户设备位于同一区域内,因此,卫星每次向这四个用户设备发送相同的有关定时提前量的信息。At this time, the satellite uses the point where the center of the satellite beam is vertically mapped to the ground as a reference point, and sends information about the timing advance (for example, including the current timing advance of the user equipment, the current timing advance of the user equipment) to the above four user equipments. At least one of the difference between the timing advance of the user equipment and the previous timing advance of the user equipment, and the time-related offset value between the current timing advance of the user equipment and the previous timing advance of the user equipment), usually Next, since the above four user equipments are located in the same area, the satellite sends the same information about the timing advance to the four user equipments each time.
图6A和6B分别示出了在不同的时刻、从用户设备发送的信号到达 电子设备200的状态的示例图。本领域技术人员可以理解,图6A和6B仅是示例而非限制。在图6A和6B中,以电子设备200为卫星为例以及以卫星向用户设备发送用户设备的当前TA为例来进行描述,假设图6A对应于T1’时刻的信号到达状态,以及图6B对应于T2’时刻的信号到达状态,其中,T2’晚于T1’。需要说明的是,为了方便,下文中以基站(卫星)的接收机的接收窗口和基站要接收的符号的CP为例进行了描述,然而,本领域技术人员可以理解,还存在其他指标用于分析ISI,这里不再累述。6A and 6B respectively show exemplary diagrams of states in which signals transmitted from the user equipment arrive at the electronic device 200 at different times. Those skilled in the art can understand that FIGS. 6A and 6B are only examples and not limitations. In FIGS. 6A and 6B , the electronic device 200 is taken as an example of a satellite and the satellite sends the current TA of the user equipment to the user equipment as an example for description. It is assumed that FIG. 6A corresponds to the signal arrival state at time T1 ′, and FIG. 6B corresponds to The signal arrives at the state at time T2', where T2' is later than T1'. It should be noted that, for convenience, the following description takes the receiving window of the receiver of the base station (satellite) and the CP of the symbol to be received by the base station as an example. However, those skilled in the art can understand that there are other indicators for Analysis of ISI, here is no longer exhaustive.
如图5所示,UE#2由于位于卫星的正下方,其从卫星接收到的当前TA正好与其所需要的TA值相等,因此,在图6A的T1’时刻,卫星接收机的接收窗口的起点恰好落在从UE#2接收到的符号的CP的结束点;然而,UE#1、UE#3和UE#4由于从卫星接收到的当前TA小于其实际需要的TA值(出现TA错误),卫星接收机从这些用户设备接收到的符号的CP的结束点晚于卫星接收机的接收窗口的起点,但是由于卫星接收机的接收窗口的起点落在从这些用户设备接收到的符号的CP范围内,所以不会引起ISI,因此,卫星接收机能够正确解码从UE#1至UE#4接收到的期望的信号。As shown in Figure 5, since UE#2 is located directly below the satellite, the current TA it receives from the satellite is exactly equal to its required TA value. Therefore, at time T1' in Figure 6A, the receiving window of the satellite receiver is equal to The starting point falls exactly at the end point of the CP of the symbol received from UE#2; however, UE#1, UE#3 and UE#4 have received TA from the satellite because the current TA is less than their actual required TA value (a TA error occurs). ), the ending point of the CP of the symbols received by the satellite receiver from these user equipments is later than the starting point of the receiving window of the satellite receiver, but since the starting point of the receiving window of the satellite receiver falls within the Within the CP range, ISI will not be caused, so the satellite receiver can correctly decode the desired signals received from UE#1 to UE#4.
随着卫星朝着远离UE#3和UE#4的方向移动和/或信道条件变化,如图6B所示,相比于T1’时刻,在T2’时刻,UE#1与卫星之间的距离减小,所以UE#1从卫星接收到的当前TA与其实际需要的TA的差距减小,卫星接收机的接收窗口的起点与从UE#1接收到的符号的CP的结束点更近并且卫星接收机的接收窗口的起点仍然落在从UE#1接收到的符号的CP范围内,所以不会引起ISI;相比于T1’时刻,在T2’时刻,UE#2与卫星之间的距离增大,所以UE#2从卫星接收到的当前TA与其实际需要的TA出现了差距(定时提前量错误),尽管卫星接收机从UE#2接收到的符号的CP的结束点晚于卫星接收机的接收窗口的起点,但是因为卫星接收机的接收窗口的起点仍然落在从UE#2接收到的符号的CP范围内,所以不会引起ISI;相比于T1’时刻,在T2’时刻,UE#3与卫星之间的距离增大,所以UE#3从卫星接收到的当前TA更小于其实际需要的TA,尽管卫星接收机从UE#3接收到的符号的CP的结束点更晚于卫星接收机的接收窗口的起点,但是因为卫星接收机的接收窗口的起点仍然落在从UE#3接收到的符号的CP范围内,所以不会引起ISI;相比于T1’时刻, 在T2’时刻,UE#4与卫星之间的距离增大,所以UE#4从卫星接收到的当前TA更小于其实际需要的TA,不但卫星接收机从UE#4接收到的符号的CP的结束点更晚于卫星接收机的接收窗口的起点并且卫星接收机从UE#4接收到的符号的CP的起点也晚于卫星接收机的接收窗口的起点,导致卫星接收机的接收窗口的起点没有落在从UE#4接收到的符号的CP范围内,因此卫星接收机的接收窗口内引入了其他符号的信息,从而会产生ISI,卫星接收机不能正确解码从UE#4接收到的期望的信号,也就是说,在UE#1至UE#4中,UE#4会对卫星接收机处的符号间干扰影响最大。As the satellite moves away from UE#3 and UE#4 and/or the channel conditions change, as shown in Figure 6B, the distance between UE#1 and the satellite at time T2' compared to time T1' decreases, so the gap between the current TA received by UE#1 from the satellite and its actual required TA decreases, the start point of the satellite receiver's receiving window is closer to the end point of the CP of the symbol received from UE#1 and the satellite The starting point of the receiver's receiving window still falls within the CP range of the symbol received from UE#1, so it will not cause ISI; compared to T1' time, at time T2', the distance between UE#2 and the satellite increases, so there is a gap between the current TA received by UE#2 from the satellite and its actual required TA (timing advance error), although the CP of the symbol received by the satellite receiver from UE#2 ends later than the satellite receives. However, since the starting point of the receiving window of the satellite receiver still falls within the CP range of the symbol received from UE#2, it will not cause ISI; compared with time T1', at time T2' , the distance between UE#3 and the satellite increases, so the current TA received by UE#3 from the satellite is smaller than the TA it actually needs, although the end point of the CP of the symbol received by the satellite receiver from UE#3 is more later than the starting point of the receiving window of the satellite receiver, but because the starting point of the receiving window of the satellite receiver still falls within the CP range of the symbol received from UE#3, it will not cause ISI; compared to time T1', At time T2', the distance between UE#4 and the satellite increases, so the current TA received by UE#4 from the satellite is smaller than the TA it actually needs, not only the CP of the symbol received by the satellite receiver from UE#4 The end point of the satellite receiver is later than the start point of the receive window of the satellite receiver and the start point of the CP of the symbol received by the satellite receiver from UE#4 is also later than the start point of the receive window of the satellite receiver, resulting in a The starting point does not fall within the CP range of the symbol received from UE#4, so the information of other symbols is introduced into the receiving window of the satellite receiver, which will generate ISI, and the satellite receiver cannot correctly decode the received symbol from UE#4. The desired signal, that is, among UE#1 to UE#4, UE#4 will have the greatest impact on the inter-symbol interference at the satellite receiver.
由以上描述可知,若不及时调度对卫星接收机处的符号间干扰影响大的用户设备(例如,处于卫星小区/波束边缘的用户设备(例如,UE#4)),该用户设备从卫星接收到的TA与其实际需要的TA的差距会越来越大,会引起ISI或导致更严重的ISI,降低该用户设备的传输效率,增加被调度的时延,从而降低用户体验。As can be seen from the above description, if the user equipment that has a large impact on the inter-symbol interference at the satellite receiver (for example, the user equipment at the edge of the satellite cell/beam (for example, UE#4)) is not scheduled in time, the user equipment receives the signal from the satellite. The gap between the received TA and the TA actually required will become larger and larger, which will cause ISI or lead to more serious ISI, reduce the transmission efficiency of the user equipment, increase the scheduled delay, and thus reduce the user experience.
图7示出了根据本公开的另一个实施例的用于无线通信的电子设备200的功能模块框图。优化地,如图7所示,根据本公开另一个实施例的电子设备200还可以包括计算单元705和调度单元707,计算单元705可以计算用户设备的与定时提前量有关的调度因子,以及调度单元707可以基于调度因子对用户设备进行调度。FIG. 7 shows a functional block diagram of an electronic device 200 for wireless communication according to another embodiment of the present disclosure. Optimally, as shown in FIG. 7 , the electronic device 200 according to another embodiment of the present disclosure may further include a calculation unit 705 and a scheduling unit 707, and the calculation unit 705 may calculate the scheduling factor related to the timing advance of the user equipment, and the scheduling Unit 707 may schedule the user equipment based on the scheduling factor.
其中,计算单元705和调度单元707可以由一个或多个处理电路实现,该处理电路例如可以实现为芯片。The computing unit 705 and the scheduling unit 707 may be implemented by one or more processing circuits, and the processing circuits may be implemented as chips, for example.
在现有技术中,基站在对用户设备进行调度时,并没有考虑用户设备的定时提前量。然而,根据本公开实施例的电子设备200能够基于用户设备的定时提前量来对用户设备进行调度,能够及时调度对电子设备200的接收机处的符号间干扰影响大的用户设备(例如,处于卫星小区/波束边缘的用户设备),避免或降低ISI以及提高该用户设备的传输效率,降低该用户设备被调度的时延,从而提高用户体验。In the prior art, the base station does not consider the timing advance of the user equipment when scheduling the user equipment. However, the electronic device 200 according to the embodiment of the present disclosure can schedule the user equipment based on the timing advance of the user equipment, and can timely schedule the user equipment that has a great influence on the inter-symbol interference at the receiver of the electronic device 200 (for example, in (user equipment at the satellite cell/beam edge), avoid or reduce ISI, improve the transmission efficiency of the user equipment, reduce the scheduling delay of the user equipment, and thus improve the user experience.
作为示例,计算单元705可以被配置为基于用户设备以当前定时提前量进行上行传输的情况下数据到达电子设备200的到达时间和电子设备200的接收窗口的起点来计算用于调度的时间长度,以及计算单元705可以被配置为基于时间长度计算调度因子。As an example, the calculating unit 705 may be configured to calculate the time length for scheduling based on the arrival time of the data arriving at the electronic device 200 and the starting point of the receiving window of the electronic device 200 in the case where the user equipment performs uplink transmission with the current timing advance, And the calculation unit 705 may be configured to calculate the scheduling factor based on the length of time.
下文中首先描述电子设备200发送给用户设备的定时提前量小于用户设备需要的定时提前量的情况,这种情况又可以分为在电子设备200的接收机处尚未出现符号间干扰和在电子设备200的接收机处已经出现符号间干扰的情形。The following first describes the situation in which the timing advance sent by the electronic device 200 to the user equipment is smaller than the timing advance required by the user equipment. A situation of inter-symbol interference has occurred at the receiver of 200.
如上文所述,如果电子设备200的接收机的接收窗口的起点落在接收到的符号的CP内时,不会引起ISI干扰。而如果由于电子设备200提供给用户设备的预定定时提前量小于用户设备需要的定时提前量导致定时提前量错误,使得用户设备以预定定时提前量进行上行传输时到达电子设备200的符号的CP的起点在时间上晚于电子设备200的接收机的接收窗口的起点(参见图6B中的UE#4),会引起ISI干扰,从而导致电子设备200无法正确解码从用户设备接收到的数据。由以上描述可知,如果用户设备以预定定时提前量进行上行传输时到达电子设备200的符号的CP的起点在时间上晚于电子设备200的接收机的接收窗口的起点,那么由于该预定定时提前量与用户设备所实际需要的定时提前量之间的差异(即,定时提前量错误),会导致电子设备200无法正确解码从用户设备接收到的符号。As described above, if the starting point of the receiving window of the receiver of the electronic device 200 falls within the CP of the received symbol, ISI interference will not be caused. However, if a timing advance error occurs because the predetermined timing advance provided by the electronic device 200 to the user equipment is smaller than the timing advance required by the user equipment, the CP of the symbol arriving at the electronic device 200 when the user equipment performs uplink transmission with the predetermined timing advance The starting point is later in time than the starting point of the receiving window of the receiver of the electronic device 200 (see UE#4 in FIG. 6B ), which may cause ISI interference, thereby causing the electronic device 200 to fail to correctly decode the data received from the user equipment. As can be seen from the above description, if the starting point of the CP of the symbol arriving at the electronic device 200 when the user equipment performs uplink transmission with a predetermined timing advance is later than the starting point of the receiving window of the receiver of the electronic device 200, then because the predetermined timing advance The difference between the timing advance amount and the timing advance actually required by the user equipment (ie, the timing advance is wrong) will cause the electronic device 200 to fail to correctly decode the symbols received from the user equipment.
图8A是示出根据本公开实施例的、电子设备200发送给用户设备的定时提前量小于用户设备需要的定时提前量并且在电子设备200的接收机处尚未出现符号间干扰的情形下,与各用户设备相对应的用于调度的时间长度的示例的图。为了比较,在图8A中,除了从电子设备200接收的当前定时提前量小于其实际需要的定时提前量的用户设备UE#1、UE#3和UE#4之外,还示出了当前没有出现定时提前量错误的用户设备UE#2。如图8A所示,示出了电子设备200的接收机的接收窗口的起点为Etime。另外,在下文中,将用户设备以当前定时提前量进行上行传输的情况下数据到达电子设备200的到达时间简称为“与当前定时提前量对应的到达时间”。在图8A中分别示出了:电子设备200从UE#1接收的数据的“与当前定时提前量对应的到达时间”Ctime1_A(即,与UE#1对应的CP的起点),电子设备200从UE#2接收的数据的“与当前定时提前量对应的到达时间”Ctime2_A(即,与UE#2对应的CP的起点),电子设备200从UE#3接收的数据的“与当前定时提前量对应的到达时间”Ctime3_A(即,与UE#3对应的CP的起点),电子设备200从UE#4接收的数据的“与当前定时提前量对应的到达时间”Ctime4_A(即,与UE#4 对应的CP的起点)。对于每个用户设备UE#1至UE#4而言,电子设备200的接收机的接收窗口的起点Etime和其“与当前定时提前量对应的到达时间”之差例如为与该电子设备对应的时间长度。例如,Etime和Ctime1_A之差为与UE#1对应的时间长度TL1_A;Etime和Ctime2_A之差例如为与UE#2对应的时间长度TL2_A;Etime和Ctime3_A之差例如为与UE#3对应的时间长度TL3_A;Etime和Ctime4_A之差例如为与UE#4对应的时间长度TL4_A。由图8A可知,与各个电子设备对应的时间长度的关系如下:TL4_A最小,TL2_A最大,TL1_A和TL3_A可能相等。在这种情况下,由于与UE#4对应的时间长度TL4_A最短,说明在UE#1至UE#4当中,UE#4最容易因为TA错误而引起ISI,因此应该及时调度UE#4。结合图8A的情形可知,随着用于调度的时间长度越短,调度因子越大。8A is a diagram illustrating a situation where the timing advance sent by the electronic device 200 to the user equipment is smaller than the timing advance required by the user equipment and ISI has not yet occurred at the receiver of the electronic device 200, according to an embodiment of the present disclosure, and A diagram of an example of the time length for scheduling corresponding to each user equipment. For comparison, in FIG. 8A , in addition to the user equipments UE#1, UE#3 and UE#4 whose current timing advance received from the electronic device 200 is smaller than their actual required timing advance, it is also shown that there is currently no User equipment UE#2 with timing advance error. As shown in FIG. 8A , it is shown that the starting point of the receiving window of the receiver of the electronic device 200 is Etime. In addition, in the following, when the user equipment performs uplink transmission with the current timing advance, the arrival time of the data arriving at the electronic device 200 is simply referred to as the "arrival time corresponding to the current timing advance". 8A respectively shows: the “arrival time corresponding to the current timing advance” Ctime1_A of the data received by the electronic device 200 from UE#1 (ie, the starting point of the CP corresponding to UE#1), the electronic device 200 from The "arrival time corresponding to the current timing advance" Ctime2_A of the data received by UE#2 (ie, the starting point of the CP corresponding to UE#2), the "arrival time corresponding to the current timing advance" of the data received by the electronic device 200 from UE#3 The corresponding arrival time "Ctime3_A" (ie, the starting point of the CP corresponding to UE#3), the "arrival time corresponding to the current timing advance" Ctime4_A of the data received by the electronic device 200 from UE#4 (ie, with UE#4 the starting point of the corresponding CP). For each user equipment UE#1 to UE#4, the difference between the start point Etime of the receiving window of the receiver of the electronic device 200 and its "arrival time corresponding to the current timing advance" is, for example, the value corresponding to the electronic device. length of time. For example, the difference between Etime and Ctime1_A is the time length TL1_A corresponding to UE#1; the difference between Etime and Ctime2_A is, for example, the time length TL2_A corresponding to UE#2; the difference between Etime and Ctime3_A is, for example, the time length corresponding to UE#3 TL3_A; the difference between Etime and Ctime4_A is, for example, the time length TL4_A corresponding to UE#4. It can be seen from FIG. 8A that the relationship between the time lengths corresponding to each electronic device is as follows: TL4_A is the smallest, TL2_A is the largest, and TL1_A and TL3_A may be equal. In this case, since the time length TL4_A corresponding to UE#4 is the shortest, it means that among UE#1 to UE#4, UE#4 is most likely to cause ISI due to TA error, so UE#4 should be scheduled in time. Combining with the situation of FIG. 8A, it can be known that as the time length for scheduling is shorter, the scheduling factor is larger.
图8B是示出根据本公开实施例的、电子设备200发送给用户设备的定时提前量小于用户设备需要的定时提前量并且在电子设备200的接收机处已经出现符号间干扰的情形下,与各用户设备相对应的用于调度的时间长度的示例的图。为了比较,在图8B中,除了从电子设备200接收的当前定时提前量小于其实际需要的定时提前量从而在电子设备200的接收机处已经导致符号间干扰的用户设备UE#3和UE#4之外,还示出了图8A中示出的当前没有出现定时提前量错误的用户设备UE#2以及从电子设备200接收的当前定时提前量小于其实际需要的定时提前量但是还没引起符号间干扰的用户设备UE#1。图8B中有关UE#1和UE#2的附图标记请参见图8A的描述,这里不再累述。在图8B中,电子设备200从UE#3接收的数据的“与当前定时提前量对应的到达时间”为Ctime3_B(即,与UE#3对应的CP的起点),电子设备200从UE#4接收的数据的“与当前定时提前量对应的到达时间”为Ctime4_B(即,与UE#4对应的CP的起点)。在图8B中,对于用户设备UE#3和UE#4而言,其“与当前定时提前量对应的到达时间”和电子设备200的接收机的接收窗口的起点Etime之差例如为与该电子设备对应的时间长度。例如,Ctime3_B与Etime之差为与UE#3对应的时间长度TL3_B;Ctime4_B与Etime之差为与UE#4对应的时间长度TL4_B。由于UE#3和UE#4在电子设备200的接收机处已经导致符号间干扰,因此,在UE#1至UE#4当中,优先调度UE#3和UE#4(即,与UE#3和UE#4对应的调度因子更大),而 对于UE#3和UE#4而言,由于UE#4所导致的符号间干扰更大(即,与UE#4对应的时间长度TL4_B大于与UE#3对应的时间长度TL3_B),因此,电子设备200优先调度UE#4(即,与UE#4对应的调度因子最大)。FIG. 8B is a diagram illustrating a situation in which the timing advance sent by the electronic device 200 to the user equipment is less than the timing advance required by the user equipment and intersymbol interference has occurred at the receiver of the electronic device 200 according to an embodiment of the present disclosure. A diagram of an example of the time length for scheduling corresponding to each user equipment. For comparison, in FIG. 8B , except for user equipments UE#3 and UE# whose current timing advance received from electronic device 200 is smaller than its actual required timing advance and thus has caused intersymbol interference at the receiver of electronic device 200 In addition to 4, it also shows that the user equipment UE#2 shown in FIG. 8A does not currently have a timing advance error and that the current timing advance received from the electronic device 200 is smaller than its actual required timing advance but has not yet caused. User equipment UE#1 with inter-symbol interference. Reference numerals related to UE#1 and UE#2 in FIG. 8B refer to the description of FIG. 8A , which will not be repeated here. In FIG. 8B , the “arrival time corresponding to the current timing advance” of the data received by the electronic device 200 from UE#3 is Ctime3_B (ie, the starting point of the CP corresponding to UE#3), and the electronic device 200 receives the data from UE#4 The "arrival time corresponding to the current timing advance" of the received data is Ctime4_B (ie, the starting point of the CP corresponding to UE#4). In FIG. 8B , for the user equipments UE#3 and UE#4, the difference between the “arrival time corresponding to the current timing advance” and the starting point Etime of the receiving window of the receiver of the electronic device 200 is, for example, the difference between the The length of time corresponding to the device. For example, the difference between Ctime3_B and Etime is the time length TL3_B corresponding to UE#3; the difference between Ctime4_B and Etime is the time length TL4_B corresponding to UE#4. Since UE#3 and UE#4 have caused inter-symbol interference at the receiver of the electronic device 200, among UE#1 to UE#4, UE#3 and UE#4 (ie, with UE#3) are preferentially scheduled The scheduling factor corresponding to UE#4 is larger), while for UE#3 and UE#4, the inter-symbol interference due to UE#4 is larger (ie, the time length TL4_B corresponding to UE#4 is larger than that of UE#4). The time length TL3_B corresponding to UE#3), therefore, the electronic device 200 schedules UE#4 preferentially (ie, the scheduling factor corresponding to UE#4 is the largest).
图8C是示出根据本公开实施例的、电子设备200发送给用户设备的定时提前量大于用户设备需要的定时提前量从而在电子设备200的接收机处出现符号间干扰的情形下,与各用户设备相对应的用于调度的时间长度的示例的图。FIG. 8C is a diagram illustrating a situation in which the timing advance sent by the electronic device 200 to the user equipment is greater than the timing advance required by the user equipment, so that intersymbol interference occurs at the receiver of the electronic device 200, and each A diagram of an example of a time length for scheduling corresponding to a user equipment.
从图8C可知,UE#1和UE#2从电子设备200接收的当前定时提前量大于其实际需要的定时提前量,因此,电子设备200从UE#1和UE#2接收到的符号的CP的结束点均早于电子设备200的接收机的接收窗口的起点,因此如图所示,在电子设备200的接收机处导致了ISI。It can be seen from FIG. 8C that the current timing advance received by UE#1 and UE#2 from the electronic device 200 is larger than the actual required timing advance. Therefore, the CP of the symbols received by the electronic device 200 from UE#1 and UE#2 The end points of both are earlier than the start of the receive window of the receiver of the electronic device 200, thus causing ISI at the receiver of the electronic device 200 as shown in the figure.
为了比较,在图8C中,除了从电子设备200接收的当前定时提前量大于其实际需要的定时提前量从而在电子设备200的接收机处已经导致符号间干扰的用户设备UE#1和UE#2(例如,UE#1引起的符号间干扰长度大于UE#2引起的符号间干扰长度,即图8C中的与UE#1对应的ISI的长度大于与UE#2对应的ISI的长度)之外,还示出了图8A中示出的从电子设备200接收的当前定时提前量小于其实际需要的定时提前量但是还没引起符号间干扰的用户设备UE#3、以及图8B中示出的从电子设备200接收的当前定时提前量小于其实际需要的定时提前量并且已经引起符号间干扰的用户设备UE#4(例如,UE#1引起的符号间干扰长度小于UE#4引起的符号间干扰长度,即图8C中的与UE#1对应的ISI的长度大于与UE#4对应的ISI的长度)。For comparison, in FIG. 8C , except for user equipments UE#1 and UE# whose current timing advance received from electronic device 200 is larger than its actual required timing advance and thus has caused intersymbol interference at the receiver of electronic device 200 2 (for example, the length of the inter-symbol interference caused by UE#1 is greater than the length of the inter-symbol interference caused by UE#2, that is, the length of the ISI corresponding to UE#1 in FIG. 8C is greater than the length of the ISI corresponding to UE#2) In addition, it also shows the user equipment UE#3 shown in FIG. 8A that the current timing advance received from the electronic device 200 is smaller than its actual required timing advance but has not caused inter-symbol interference, and the user equipment UE#3 shown in FIG. 8B The current timing advance received from the electronic device 200 is smaller than its actual required timing advance and the user equipment UE#4 that has caused ISI (for example, the length of the ISI caused by UE#1 is smaller than the symbol caused by UE#4 inter-interference length, that is, the length of the ISI corresponding to UE#1 in FIG. 8C is greater than the length of the ISI corresponding to UE#4).
在图8C中分别示出了:电子设备200从UE#1接收的数据的“与当前定时提前量对应的到达时间”Ctime1_C(即,与UE#1对应的CP的起点),电子设备200从UE#2接收的数据的“与当前定时提前量对应的到达时间”Ctime2_C(即,与UE#2对应的CP的起点),电子设备200从UE#3接收的数据的“与当前定时提前量对应的到达时间”Ctime3_C(即,与UE#3对应的CP的起点),电子设备200从UE#4接收的数据的“与当前定时提前量对应的到达时间”Ctime4_C(即,与UE#4对应的CP的起点)。8C respectively shows: the "arrival time corresponding to the current timing advance" Ctime1_C of the data received by the electronic device 200 from the UE#1 (ie, the starting point of the CP corresponding to the UE#1), the electronic device 200 from the UE#1 The "arrival time corresponding to the current timing advance" Ctime2_C of the data received by UE#2 (ie, the starting point of the CP corresponding to UE#2), the "arrival time corresponding to the current timing advance" of the data received by the electronic device 200 from UE#3 The corresponding arrival time "Ctime3_C" (ie, the starting point of the CP corresponding to UE#3), the "arrival time corresponding to the current timing advance" Ctime4_C of the data received by the electronic device 200 from UE#4 (ie, with UE#4 the starting point of the corresponding CP).
在图8C中,对于用户设备UE#1和UE#2而言,例如,可以先计算 电子设备200的接收机的接收窗口的起点Etime与其“与当前定时提前量对应的到达时间”之间的差值,然后将所计算出的差值加上CP的长度(假设为CPL)后所得到的值作为与该电子设备对应的时间长度,该时间长度可以反映由用户设备UE#1和UE#2所引起的符号间干扰的长度。例如,与UE#1对应的时间长度TL1_C=Etime-Ctime1_C+CPL,与UE#2对应的时间长度TL2_C=Etime-Ctime2_C+CPL。参照图8A可知,与UE#3对应的时间长度TL3_C=Etime-Ctime3_C。参照图8B可知,与UE#4对应的时间长度TL4_C=Ctime4_C-Etime。由于UE#1、UE#2和UE#4在电子设备200的接收机处已经导致符号间干扰,因此,在UE#1至UE#4当中,UE#1、UE#2和UE#4的调度优先级高于UE#3的调度优先级。而对于UE#1、UE#2和UE#4而言,优先调度所导致的符号间干扰更大的用户设备,因为TL4_C>TL1_C>TL2_C,因此,UE#4的调度优先级>UE#1的调度优先级>UE#2的调度优先级(即,与UE#4对应的调度因子>与UE#1对应的调度因子>与UE#2对应的调度因子)。In FIG. 8C , for the user equipments UE#1 and UE#2, for example, the difference between the start point Etime of the receiving window of the receiver of the electronic device 200 and its "arrival time corresponding to the current timing advance" can be calculated first. difference value, and then add the calculated difference value to the length of the CP (assuming CPL) as the time length corresponding to the electronic device, and the time length can reflect the difference between the user equipment UE#1 and UE# 2 The length of the intersymbol interference caused. For example, time length TL1_C=Etime-Ctime1_C+CPL corresponding to UE#1, and time length TL2_C=Etime-Ctime2_C+CPL corresponding to UE#2. Referring to FIG. 8A , it can be seen that the time length TL3_C=Etime−Ctime3_C corresponding to UE#3. Referring to FIG. 8B , it can be seen that the time length TL4_C=Ctime4_C-Etime corresponding to UE#4. Since UE#1, UE#2 and UE#4 have caused inter-symbol interference at the receiver of the electronic device 200, among UE#1 to UE#4, UE#1, UE#2 and UE#4 have The scheduling priority is higher than that of UE#3. For UE#1, UE#2 and UE#4, the user equipment with greater inter-symbol interference caused by priority scheduling, because TL4_C>TL1_C>TL2_C, therefore, the scheduling priority of UE#4>UE#1 The scheduling priority of > UE#2's scheduling priority (ie, the scheduling factor corresponding to UE#4 > the scheduling factor corresponding to UE#1 > the scheduling factor corresponding to UE#2).
图9是示出根据本公开实施例的电子设备200对用户设备进行调度的示例的图。图9是结合图8A中的用户设备UE#1至UE#4而进行描述的。由图8A可知,在尚未引起ISI的用户设备UE#1至UE#4当中,由于与处于卫星小区/波束边缘的UE#4对应的时间长度最短,UE#4最容易因为TA错误而引起ISI,因此,如图9所示,电子设备200优先对UE#4进行调度。FIG. 9 is a diagram illustrating an example of scheduling a user equipment by the electronic device 200 according to an embodiment of the present disclosure. FIG. 9 is described in conjunction with the user equipments UE#1 to UE#4 in FIG. 8A. As can be seen from FIG. 8A , among the user equipments UE#1 to UE#4 that have not yet caused ISI, since the time length corresponding to UE#4 at the satellite cell/beam edge is the shortest, UE#4 is most likely to cause ISI due to TA errors. , therefore, as shown in FIG. 9 , the electronic device 200 preferentially schedules UE#4.
图10是示出根据本公开实施例的在不同时间对用户设备进行调度的示例的图。图10是结合图8A中的用户设备UE#1至UE#4而进行描述的。在图10中,示出了图8A中的四个用户设备UE#1至UE#4,并且示出了在时间T1-T8期间,UE#1至UE#4的TA状况,以UE#4为例,时间T4的“TA ok”表示如果UE#4在时间T4被调度,则UE#4的定时提前量不会导致在电子设备200处产生ISI,而时间T5中的“TA NG”表示如果UE#4在时间T5被调度,则UE#4的定时提前量会导致在电子设备200处产生ISI。在图10中,假设电子设备200收到UE#2和UE#4的调度请求。结合图8A可知,由于与UE#4对应的时间长度最短,所以电子设备200会优先调度UE#4。假设电子设备200在T4中优先调度UE#4,如图10所示,UE#4在时间T4为“TA ok”,则UE#4的定时提前量不会导致在电子设备200处产生ISI。另外,即使相比与UE#4更晚调度UE#2 (例如,在T5调度UE#2),因为UE#2在时间T5-T8均为“TA ok”,则UE#2的定时提前量也不会导致在电子设备200处产生ISI。相反,如果不考虑用户设备的定时提前量,则可能会在T5中调度UE#4,如图10所示,UE#4在时间T5中为“TA NG”,则UE#4的定时提前量会导致在电子设备200处产生ISI。FIG. 10 is a diagram illustrating an example of scheduling user equipment at different times according to an embodiment of the present disclosure. FIG. 10 is described in conjunction with the user equipments UE#1 to UE#4 in FIG. 8A. In Fig. 10, the four user equipments UE#1 to UE#4 in Fig. 8A are shown, and the TA conditions of UE#1 to UE#4 during time T1-T8 are shown, with UE#4 For example, "TA ok" at time T4 indicates that if UE#4 is scheduled at time T4, the timing advance of UE#4 will not cause ISI to be generated at electronic device 200, while "T ANG" at time T5 indicates that If UE#4 was scheduled at time T5, the timing advance of UE#4 would cause an ISI to be generated at the electronic device 200. In FIG. 10, it is assumed that the electronic device 200 receives scheduling requests from UE#2 and UE#4. With reference to FIG. 8A , since the time length corresponding to UE#4 is the shortest, the electronic device 200 will schedule UE#4 preferentially. Assuming that the electronic device 200 schedules UE#4 preferentially in T4, as shown in FIG. 10, UE#4 is "TA ok" at time T4, the timing advance of UE#4 will not cause ISI to be generated at the electronic device 200. In addition, even if UE#2 is scheduled later than UE#4 (eg, UE#2 is scheduled at T5), since UE#2 is "TA ok" at times T5-T8, the timing advance of UE#2 Nor does it result in ISI being generated at the electronic device 200 . Conversely, if the timing advance of the user equipment is not considered, UE#4 may be scheduled in T5, as shown in Figure 10, UE#4 is "T ANG" in time T5, then the timing advance of UE#4 This can result in ISI being generated at the electronic device 200 .
作为示例,时间长度还与电子设备200的在发生符号间干扰情况下的解码能力有关。As an example, the length of time is also related to the decoding capability of the electronic device 200 in the presence of intersymbol interference.
在结合图8A进行的描述中,假设在用户设备进行上行传输时到达电子设备200的符号的CP的起点在时间上正好与电子设备200的接收机的接收窗口的起点重合的情况下,电子设备200就可能无法正确解码从用户设备接收到的数据,以UE#4为例,在图8A中,与UE#4对应的时间长度可以表示为Etime-Ctime4_A。然而,在电子设备200的接收机能力强的情况下,即使用户设备进行上行传输时到达电子设备200的符号的CP的起点在时间上比电子设备200的接收机的接收窗口的起点晚预定值之内(比如CP的长度的预定比例(例如10%)以内),即存在一定的ISI(比如10%以内的ISI,也可以说ISI比例为10%以内),也能正确解码出所接收到的数据,仍以UE#4为例,这种情况下与UE#4对应的时间长度可以表示为Etime-Ctime4_A+CP的长度x预定比例。此外,对于结合图8B-8C描述的情形,用户设备的时间长度也还与电子设备200的在发生符号间干扰情况下的解码能力有关,这里不再累述。In the description in conjunction with FIG. 8A , it is assumed that the starting point of the CP of the symbol arriving at the electronic device 200 coincides with the starting point of the receiving window of the receiver of the electronic device 200 when the user equipment performs uplink transmission. 200, the data received from the user equipment may not be correctly decoded. Taking UE#4 as an example, in FIG. 8A, the time length corresponding to UE#4 can be represented as Etime-Ctime4_A. However, when the receiver of the electronic device 200 is capable, even if the user equipment performs uplink transmission, the starting point of the CP of the symbol reaching the electronic device 200 is later than the starting point of the receiving window of the receiver of the electronic device 200 by a predetermined value in time. (for example, within a predetermined ratio (for example, 10%) of the length of the CP), that is, there is a certain ISI (for example, the ISI within 10%, or the ISI ratio is within 10%), the received data can also be decoded correctly. For data, still take UE#4 as an example, in this case, the time length corresponding to UE#4 can be expressed as the length of Etime-Ctime4_A+CP x a predetermined ratio. In addition, for the situations described in conjunction with FIGS. 8B-8C, the time length of the user equipment is also related to the decoding capability of the electronic device 200 in the case of inter-symbol interference, which is not repeated here.
作为示例,计算单元705可以被配置为基于用户设备的位置、电子设备200与用户设备之间的夹角、用户设备是否临近切换、用户设备进行上行传输时的数据包的大小中的至少之一,计算调度因子。以这种方式,电子设备200能够基于用户设备的位置、电子设备与用户设备之间的夹角、用户设备是否临近切换、用户设备进行上行传输时的数据包的大小中的至少之一,对用户设备进行调度。As an example, the computing unit 705 may be configured to be based on at least one of the location of the user equipment, the angle between the electronic device 200 and the user equipment, whether the user equipment is close to handover, and the size of the data packet when the user equipment performs uplink transmission , calculate the scheduling factor. In this way, the electronic device 200 can, based on at least one of the position of the user equipment, the angle between the electronic device and the user equipment, whether the user equipment is close to handover, and the size of the data packet when the user equipment performs uplink transmission, to The user equipment performs scheduling.
作为示例,用户设备包括多个用户设备,以及调度单元707可以被配置为在多个用户设备当中调度具有最大的调度因子的用户设备。即,电子设备200可以直接基于调度因子来对用户设备进行调度。As an example, the user equipment includes multiple user equipments, and the scheduling unit 707 may be configured to schedule the user equipment with the largest scheduling factor among the multiple user equipments. That is, the electronic device 200 may schedule the user equipment directly based on the scheduling factor.
此外,电子设备200还可以基于调度因子、结合其他因素来对用户设备进行调度。作为示例,调度单元707可以被配置为计算每个用户设 备的当前请求的通信速率与累积平均通信速率之间的比值,并计算该比值与调度因子的乘积,以及调度多个用户设备当中的、具有最大的乘积的用户设备。In addition, the electronic device 200 may also schedule the user equipment based on the scheduling factor in combination with other factors. As an example, the scheduling unit 707 may be configured to calculate the ratio between the currently requested communication rate and the cumulative average communication rate of each user equipment, calculate the product of the ratio and the scheduling factor, and schedule, among the plurality of user equipments, The user equipment with the largest product.
假设用户设备i(1≤i≤N,N为用户设备的总数)的调度因子为TAF i,R i(t)为用户设备i在t时刻请求的通信速率,T i(t)为用户设备i在t时刻的累积平均通信速率,则被调度用户设备k可以表示为: Assuming that the scheduling factor of user equipment i (1≤i≤N, N is the total number of user equipments) is TAF i , R i (t) is the communication rate requested by user equipment i at time t, and T i (t) is the user equipment The cumulative average communication rate of i at time t, the scheduled user equipment k can be expressed as:

以这种方式,电子设备200不仅考虑用户设备的与定时提前量有关的调度因子、还考虑了用户设备的当前请求的通信速率与累积平均通信速率来对用户设备进行调度。In this way, the electronic device 200 schedules the user equipment considering not only the scheduling factor related to the timing advance of the user equipment, but also the current requested communication rate and the cumulative average communication rate of the user equipment.

Here, it should also be noted that the electronic device 1100 may be implemented at the chip level, or may also be implemented at the device level.
