Abstract

Said method comprises: a terminal device receiving a group common physical downlink control channel (PDCCH), the group common PDCCH comprising timing deviation indication information; and the terminal device determining target timing deviation information according to the timing deviation indication information.
Description
本申请实施例涉及通信领域,具体涉及一种无线通信的方法、终端设备和网络设备。The embodiments of the present application relate to the field of communications, and in particular to a wireless communication method, terminal device, and network device.
在新无线(New Radio,NR)***中,终端设备可以在时隙n接收调度物理上行共享信道(Physical Uplink Shared Channel,PUSCH)的下行控制信息(Downlink Control Information,DCI),然后可以在时隙n’+K2发送PUSCH,该时隙n’可以根据PUSCH和物理下行控制信道(Physical Downlink Control Channel,PDCCH)的子载波间隔确定,其中,K2为PUSCH和PDCCH之间的定时偏差。In the New Radio (NR) system, the terminal device can receive the downlink control information (Downlink Control Information, DCI) for scheduling the Physical Uplink Shared Channel (PUSCH) in the time slot n, and then can receive the downlink control information (DCI) in the time slot n. n'+K2 transmits the PUSCH, and the time slot n'can be determined according to the subcarrier interval between the PUSCH and the physical downlink control channel (Physical Downlink Control Channel, PDCCH), where K2 is the timing deviation between the PUSCH and the PDCCH.
在陆地蜂窝通信中通信半径通常较小,因此,上下行通信的路径传输时延较短,因此,对定时偏差K2的影响不大。在NR***中,考虑采用卫星通信的方式给终端设备提供通信服务,卫星通信的通信半径较大,路径传输时延较大,会对定时偏差K2产生影响,此情况下,如何确定定时偏差以保证数据的正确传输是一项亟需解决的问题。In terrestrial cellular communication, the communication radius is usually small. Therefore, the path transmission delay of the uplink and downlink communication is short, and therefore, the influence on the timing deviation K2 is not large. In the NR system, consider the use of satellite communication to provide communication services to the terminal equipment. The communication radius of satellite communication is large and the path transmission delay is large, which will affect the timing deviation K2. In this case, how to determine the timing deviation Ensuring the correct transmission of data is a problem that needs to be solved urgently.

在NR***中可以具有如下定时偏差:There can be the following timing deviations in the NR system:
1、PUSCH和PDCCH之间的定时偏差1. Timing deviation between PUSCH and PDCCH
假设终端设备在时隙n接收到调度PUSCH的DCI,则终端设备发送PUSCH的时隙
Assuming that the terminal device receives the DCI scheduling PUSCH in time slot n, the terminal device sends the PUSCH time slot
2、PDSCH和PUCCH之间的定时偏差2. Timing deviation between PDSCH and PUCCH
如果终端设备在时隙n接收到基于DCI格式(format)1_0或DCI format1_1调度的物理下行共享信道(Physical Downlink Shared Channel,PDSCH),或,若终端设备在时隙n接收到通过PDCCH传输的一个DCI format1_0指示的半静态调度(Semi-Persistent Scheduling,SPS)PDSCH释放信令,则终端设备在时隙n+k发送对应的混合自动请求重传确认(Hybrid Automatic Repeat reQuest-ACKnowledge,HARQ-ACK)信息,其中,k是DCI格式中的PDSCH到HARQ定时域(PDSCH-to-HARQ-timing-indicator)所指示的时隙数目,例如,DCI format1_0中的3比特,用于指示1~8个时隙,DCI format1_1中的4比特用于指示1~16个时隙,或k也可以由信令下行数据到上行反馈(dl-DataToUL-ACK)指示。If the terminal device receives a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) scheduled based on DCI format 1_0 or DCI format 1_1 in time slot n, or if the terminal device receives a PDCCH transmitted through PDCCH in time slot n Semi-Persistent Scheduling (SPS) PDSCH release signaling indicated by DCI format 1_0, the terminal device sends the corresponding Hybrid Automatic Repeat reQuest-ACKnowledge (Hybrid-Automatic Repeat reQuest-ACKnowledge, HARQ-ACK) in time slot n+k Information, where k is the number of time slots indicated by the PDSCH-to-HARQ-timing-indicator in the DCI format. For example, the 3 bits in DCI format 1_0 are used to indicate 1 to 8 time slots. Slot, 4 bits in DCI format1_1 are used to indicate 1-16 time slots, or k can also be indicated by signaling downlink data to uplink feedback (dl-DataToUL-ACK).
3、CSI上报的定时偏差3. Timing deviation reported by CSI
NR***支持非周期信道状态信息(Channel State Information,CSI)上报和半持续 CSI上报,两种CSI上报均通过DCI激活/触发并通过PUSCH承载。PUSCH与激活/触发CSI上报的DCI之间的时隙偏差的可能取值可以通过高层信令参数,如报告时隙偏差表(reportSlotOffsetList)配置,取值范围可以为0-32时隙,实际使用的时隙偏差k通过激活/触发CSI上报的DCI指示。The NR system supports aperiodic channel state information (CSI) reporting and semi-persistent CSI reporting. Both CSI reporting are activated/triggered by DCI and carried by PUSCH. The possible value of the time slot offset between PUSCH and DCI reported by activated/triggered CSI can be configured through high-level signaling parameters, such as the report slot offset list (reportSlotOffsetList). The value range can be 0-32 time slots. Actual use The time slot deviation k is indicated by activating/triggering the DCI reported by the CSI.
4、CSI参考资源的定时偏差n
CSI_ref
4. Timing deviation of CSI reference resource n CSI_ref
CSI参考资源用于CSI测量是测量服务小区的干扰情况,在时域上,终端设备可以在上行时隙n'进行CSI上报的CSI参考资源位于单独的下行时隙
其中,μ
DL和μ
UL分别为下行和上行的子载波间隔。
The CSI reference resource is used for CSI measurement to measure the interference of the serving cell. In the time domain, the terminal equipment can report the CSI in the uplink time slot n'. The CSI reference resource is located in a separate downlink time slot. Among them, μ DL and μ UL are the downlink and uplink subcarrier spacing respectively.
目前正在研究基于5G NR的非地面通信网络(Non Terrestrial Network,NTN)技术,NTN技术一般采用卫星通信的方式向地面用户提供通信服务,相对于地面蜂窝网络通信,卫星通信不受用户地域的限制,对于一般的陆地通信不能覆盖海洋、高山、沙漠等无法搭设通信设备或由于人口稀少而不做通信覆盖的区域,可以通过卫星进行覆盖,并且卫星可以围绕地球做轨道运动,因此,基本上地球上每一个角落都可以被卫星通讯覆盖。Currently, research is underway on 5G NR-based Non-Terrestrial Network (NTN) technology. NTN technology generally uses satellite communications to provide communications services to ground users. Compared with terrestrial cellular network communications, satellite communications are not restricted by user geographic areas. For general terrestrial communications that cannot cover oceans, mountains, deserts and other areas where communications equipment cannot be installed or are not covered by communications due to sparse population, satellites can be used for coverage, and satellites can orbit the earth. Therefore, basically the earth Every corner can be covered by satellite communications.
在卫星通信场景,下行链路(从卫星到终端设备的链路)和上行链路(从终端设备到卫星的链路)都有较长的路径传播时延,对于低轨道卫星一般单向传播时延为几个微秒,对于地球同步轨道卫星单向传播时延一般为几百个微秒,这些时延对于上述定时偏差已经不可忽视,因此,如何进行定时偏差调整是一项亟需解决的问题。In the satellite communication scenario, both the downlink (the link from the satellite to the terminal device) and the uplink (the link from the terminal device to the satellite) have a long path propagation delay, and for low-orbit satellites generally one-way propagation The time delay is several microseconds. For geosynchronous orbit satellites, the one-way propagation delay is generally several hundred microseconds. These delays cannot be ignored for the above-mentioned timing deviation. Therefore, how to adjust the timing deviation is an urgent need to solve The problem.
图3为本申请实施例提供的一种无线通信的方法200的示意性流程图。该方法200可以由图1所示的通信***中的终端设备执行,如图3所示,该方法200可以包括如下至少部分内容:FIG. 3 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the application. The method 200 may be executed by the terminal device in the communication system shown in FIG. 1. As shown in FIG. 3, the method 200 may include at least part of the following content:

S220,所述终端设备根据所述定时偏差指示信息,确定目标定时偏差信息。S220: The terminal device determines target timing deviation information according to the timing deviation indication information.
因此,在本申请实施例中,采用Group-common PDCCH可以实现更加动态的向终端设备通知定时偏差,从而能够适应卫星通信场景中卫星与终端设备之间的距离的快速变化。Therefore, in the embodiment of the present application, the Group-common PDCCH can be used to more dynamically notify the terminal device of the timing deviation, thereby being able to adapt to the rapid change of the distance between the satellite and the terminal device in the satellite communication scenario.
应理解,在本申请实施例中,网络设备可以通过其他动态信令通知该定时偏差指示信息,本申请实施例对此不作限定。It should be understood that, in the embodiment of the present application, the network device may notify the timing deviation indication information through other dynamic signaling, which is not limited in the embodiment of the present application.
在本申请实施例中,该定时偏差指示信息可以用于确定所述目标定时偏差信息,该目标定时偏差(记为K_offset)可以为网络设备和终端设备之间的传播路径导致的传播延时,或称,补偿定时偏差。In the embodiment of the present application, the timing deviation indication information may be used to determine the target timing deviation information, and the target timing deviation (denoted as K_offset) may be the propagation delay caused by the propagation path between the network device and the terminal device, In other words, to compensate for timing deviation.
在一些实施例中,所述定时偏差指示信息可以包括网络设备和终端设备之间的单向传播延时,例如上行链路的传播延时,或下行链路的传播延时,在另一些实施例中,所述定时偏差指示信息可以包括网络设备和终端设备之间的往返传播延时,例如,上行链路的传播延时和下行链路的传播延时之和。以下,以定时偏差指示信息为单向传播延时为例进行说明。In some embodiments, the timing deviation indication information may include the one-way propagation delay between the network device and the terminal device, such as the propagation delay of the uplink or the propagation delay of the downlink. In other implementations, In an example, the timing deviation indication information may include the round-trip propagation delay between the network device and the terminal device, for example, the sum of the propagation delay of the uplink and the propagation delay of the downlink. In the following, the timing deviation indication information is a one-way propagation delay as an example for description.
可选地,在本申请实施例中,所述目标定时偏差信息K_offset可以用于补偿以下定时偏差中的至少一种:Optionally, in this embodiment of the present application, the target timing offset information K_offset may be used to compensate for at least one of the following timing offsets:
PUSCH和物理下行控制信道(Physical Downlink Control Channel,PDCCH)之间的定时偏差K2;The timing deviation K2 between PUSCH and Physical Downlink Control Channel (PDCCH);
物理下行共享信道(Physical Downlink Shared Channel,PDSCH)与物理上行控制信道(Physical Uplink Control Channel,PUCCH)之间的定时偏差k;The timing deviation k between the physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) and the physical uplink control channel (Physical Uplink Control Channel, PUCCH);
信道状态信息(Channel State Information,CSI)上报的定时偏差;Channel State Information (CSI) reporting timing deviation;
CSI参考资源的定时偏差。The timing deviation of the CSI reference resource.
对于PDCCH与PUSCH之间的定时偏差K2,网络设备在时隙n向终端设备发送PDCCH,终端设备在经历K_offset1之后接收到PDCCH,若该PDCCH指示终端设备在时隙n+K2发送PUSCH,则该终端设备可以根据该定时偏差K2发送PUSCH,该PUSCH需要经历K_offset1到达网络设备,网络设备期望在时隙n+K2+2K_offset1接收到所述 PUSCH。因此,本申请实施例中,在定时偏差K2的基础上,网络设备进一步通知K_offset1给终端设备,从而所述终端设备可以根据所述定时偏差K2和K_offset1调整PUSCH的发送定时,以使网络设备在时隙n+K2+2K_offset1接收到所述PUSCH。For the timing deviation K2 between the PDCCH and PUSCH, the network device sends the PDCCH to the terminal device in time slot n, and the terminal device receives the PDCCH after experiencing K_offset1. If the PDCCH instructs the terminal device to send PUSCH in time slot n+K2, then The terminal device may send the PUSCH according to the timing deviation K2, and the PUSCH needs to experience K_offset1 to reach the network device, and the network device expects to receive the PUSCH in the time slot n+K2+2K_offset1. Therefore, in this embodiment of the application, on the basis of the timing deviation K2, the network device further notifies K_offset1 to the terminal device, so that the terminal device can adjust the PUSCH transmission timing according to the timing deviation K2 and K_offset1, so that the network device The PUSCH is received in time slot n+K2+2K_offset1.
对于终端设备侧的定时来说,若终端设备在时隙n接收到网络设备发送的PDCCH,该PDCCH指示终端设备在时隙n+K2发送PUSCH,由于该PUSCH需要经历K_offset1才能到达网络设备,网络设备期望在时隙n+K2+K_offset1接收到所述PUSCH。因此,本申请实施例中,在定时偏差K2的基础上,网络设备进一步通知K_offset1给终端设备,从而所述终端设备可以根据所述定时偏差K2和K_offset1调整PUSCH的发送定时,以使网络设备在时隙n+K2+K_offset1接收到所述PUSCH。For the timing of the terminal device side, if the terminal device receives the PDCCH sent by the network device in the time slot n, the PDCCH instructs the terminal device to send the PUSCH in the time slot n+K2. Because the PUSCH needs to experience K_offset1 to reach the network device, the network The device expects to receive the PUSCH in the time slot n+K2+K_offset1. Therefore, in this embodiment of the application, on the basis of the timing deviation K2, the network device further notifies K_offset1 to the terminal device, so that the terminal device can adjust the PUSCH transmission timing according to the timing deviation K2 and K_offset1, so that the network device The PUSCH is received in time slot n+K2+K_offset1.
类似地,对应于PUCCH与PDSCH之间的定时偏差K1,如果终端设备在时隙n接收到基于DCI格式1_0或DCI格式1_1调度的PDSCH,或者,在时隙n接收到通过PDCCH传输的一个DCI格式1_0指示的SPS PDSCH释放信令,则该终端设备可以基于该定时偏差K1发送PUCCH,用于承载该PDSCH的HARQ-ACK信息,由于在卫星通信场景中,路径传播时延较大,该HARQ-ACK信息需要经历K_offset2才能到达网络设备,网络设备期望在时隙n+K1+K_offset2接收到所述PUCCH。因此,在定时偏差K1的基础上,网络设备进一步通知K_offset2给终端设备,从而所述终端设备可以根据所述定时偏差K1和K_offset2调整PUCCH的发送定时,以使网络设备在时隙n+K1+K_offset2接收到所述PUSCH。Similarly, corresponding to the timing deviation K1 between PUCCH and PDSCH, if the terminal device receives a PDSCH scheduled based on DCI format 1_0 or DCI format 1_1 in time slot n, or receives a DCI transmitted through PDCCH in time slot n The SPS PDSCH release signaling indicated by the format 1_0, the terminal device can send PUCCH based on the timing deviation K1 to carry the HARQ-ACK information of the PDSCH. In the satellite communication scenario, the path propagation delay is large, the HARQ -ACK information needs to experience K_offset2 to reach the network device, and the network device expects to receive the PUCCH in the time slot n+K1+K_offset2. Therefore, on the basis of the timing deviation K1, the network device further informs K_offset2 to the terminal device, so that the terminal device can adjust the PUCCH transmission timing according to the timing deviation K1 and K_offset2, so that the network device is in the time slot n+K1+ K_offset2 receives the PUSCH.
类似地,对于承载CSI反馈的PUSCH与激活/触发CSI上报的DCI之间的定时偏差k,若终端设备在时隙n接收到激活/触发CSI上报的DCI指示,则终端设备可以基于该定时偏差k进行CSI上报,由于在卫星通信场景中,路径传播时延较大,终端设备上报的该CSI需要经历K_offset3才能到达网络设备,网络设备期望在时隙n+k+K_offset3接收到所述CSI。因此,在本申请实施例中,在定时偏差k的基础上,网络设备进一步通知K_offset3给终端设备,从而所述终端设备可以根据所述定时偏差k和K_offset3调整CSI的发送定时,以使网络设备在时隙n+k+K_offset3接收到所述CSI。Similarly, for the timing deviation k between the PUSCH carrying CSI feedback and the DCI that activates/triggers the CSI report, if the terminal device receives the DCI indication that activates/triggers the CSI report in time slot n, the terminal device can be based on the timing deviation k performs CSI reporting. In the satellite communication scenario, the path propagation delay is relatively large. The CSI reported by the terminal device needs to experience K_offset3 before reaching the network device. The network device expects to receive the CSI in the time slot n+k+K_offset3. Therefore, in the embodiment of the present application, on the basis of the timing deviation k, the network device further notifies K_offset3 to the terminal device, so that the terminal device can adjust the CSI transmission timing according to the timing deviation k and K_offset3, so that the network device The CSI is received in time slot n+k+K_offset3.
类似地,对于CSI参考资源的定时偏差,若网络设备在时隙n接收终端设备的CSI上报,由于在卫星通信场景中,路径传播时延较大,终端设备上报的CSI需要经历K_offset4到达网络设备,因此,在本申请实施例中,在定时偏差n
CSI_ref的基础上,网络设备进一步通知K_offset4给终端设备,从而所述终端设备可以根据所述定时偏差n
CSI_ref和K_offset4调整CSI参考资源的定时,例如将CSI参考资源的定时调整为n-n
CSI_ref-K_offset4,以使网络设备在时隙n接收到所述终端设备上报的CSI。
Similarly, for the timing deviation of the CSI reference resource, if the network device receives the CSI report of the terminal device in time slot n, since the path propagation delay is large in the satellite communication scenario, the CSI reported by the terminal device needs to go through K_offset4 to reach the network device Therefore, in this embodiment of the application, on the basis of the timing deviation n CSI_ref , the network device further informs K_offset4 to the terminal device, so that the terminal device can adjust the timing of the CSI reference resource according to the timing deviation n CSI_ref and K_offset4, For example, the timing of the CSI reference resource is adjusted to nn CSI_ref- K_offset4, so that the network device receives the CSI reported by the terminal device in the time slot n.

具体地,所述终端设备可以根据所述定时偏差指示信息,确定第一定时偏差信息,具体实现可以参考实施例一和实施例二中根据定时偏差指示信息确定目标定时偏差信息的相关描述,为了简洁,这里不再赘述。Specifically, the terminal device may determine the first timing deviation information according to the timing deviation indication information. For specific implementation, refer to the description of determining target timing deviation information according to the timing deviation indication information in Embodiment 1 and Embodiment 2. Concise, I won't repeat it here.
作为一个示例,所述定时偏差指示信息包括用于所述组的公共定时偏差信息,此情况下,所述终端设备可以将所述组的公共定时偏差信息确定为所述第一定时偏差信息。以PDCCH与PUSCH之间的定时为例,如果所述组的公共定时偏差信息为60,时间单 元为5ms,则可以确定目标定时偏差为300ms,若所述终端设备在时隙n接收到PDCCH,进一步地,所述终端设备可以基于PDCCH与PUSCH之间的定时偏差K2和该目标定时偏差300,调整PUSCH的发送定时,以使网络设备在期望的时刻(即时隙n+K2+300ms)接收所述PUSCH。As an example, the timing deviation indication information includes common timing deviation information for the group. In this case, the terminal device may determine the common timing deviation information of the group as the first timing deviation information. Taking the timing between PDCCH and PUSCH as an example, if the common timing deviation information of the group is 60 and the time unit is 5ms, it can be determined that the target timing deviation is 300ms. If the terminal device receives the PDCCH in time slot n, Further, the terminal device may adjust the PUSCH transmission timing based on the timing deviation K2 between the PDCCH and the PUSCH and the target timing deviation 300, so that the network device can receive the data at the desired time (ie, time slot n+K2+300ms).述PUSCH.
作为另一示例,所述定时偏差指示信息包括定时偏差调整量,其中,所述定时偏差调整量为相对于所述组的第一公共定时偏差信息的调整量,此情况下,所述终端设备可以根据所述定时偏差调整量和所述组的第一公共定时偏差信息确定所述第一定时偏差信息,例如,所述终端设备可以将所述定时偏差调整量和所述组的第一公共定时偏差信息之和,确定为所述第一定时偏差信息。应注意,这里的所述组的第一公共定时偏差信息可以从***信息获取,或者也可以从Group-common PDCCH获取。As another example, the timing deviation indication information includes a timing deviation adjustment amount, wherein the timing deviation adjustment amount is an adjustment amount relative to the first common timing deviation information of the group. In this case, the terminal device The first timing deviation information may be determined according to the timing deviation adjustment amount and the first common timing deviation information of the group. For example, the terminal device may compare the timing deviation adjustment amount to the first common timing deviation information of the group. The sum of timing deviation information is determined as the first timing deviation information. It should be noted that the first common timing offset information of the group here may be obtained from system information, or may also be obtained from Group-common PDCCH.
以PDCCH与PUSCH之间的定时为例,如果所述组的第一公共定时偏差信息为60,时间单元为5ms,所述定时偏差调整量为10,时间单元为1ms,则可以确定目标定时偏差为310ms,若所述终端设备在时隙n接收到PDCCH,进一步地,所述终端设备可以基于PDCCH与PUSCH之间的定时偏差K2和该目标定时偏差310,调整PUSCH的发送定时,以使网络设备在期望的时刻(即时隙n+K2+310ms)接收所述PUSCH。Taking the timing between PDCCH and PUSCH as an example, if the first common timing deviation information of the group is 60, the time unit is 5ms, the timing deviation adjustment is 10, and the time unit is 1ms, then the target timing deviation can be determined If the terminal device receives the PDCCH in time slot n, the terminal device can adjust the PUSCH transmission timing based on the timing deviation K2 between the PDCCH and the PUSCH and the target timing deviation 310, so that the network The device receives the PUSCH at a desired time (that is, time slot n+K2+310ms).
进一步地,所述终端设备可以根据所述第一定时偏差信息,结合所述终端设备当前使用的子载波间隔和所述参考子载波间隔的关系,确定所述目标定时偏差信息。例如,将所述第一定时偏差信息乘以特定比值的结果确定为所述目标定时偏差信息,其中,所述特定比值为当前使用的子载波间隔和所述参考子载波间隔的比值。Further, the terminal device may determine the target timing deviation information according to the first timing deviation information in combination with the relationship between the subcarrier interval currently used by the terminal device and the reference subcarrier interval. For example, a result of multiplying the first timing deviation information by a specific ratio is determined as the target timing deviation information, where the specific ratio is the ratio of the currently used subcarrier interval to the reference subcarrier interval.
例如,若参考子载波间隔为15KHz,表示定时偏差为K_offset个15KHz的时隙。以PDCCH与PUSCH之间的定时为例,如果终端设备当前工作的上行BWP为30KHz,则目标定时偏差为30/15*K_offset=2*K_offset个30KHz的时隙。For example, if the reference subcarrier interval is 15KHz, it means that the timing deviation is K_offset timeslots of 15KHz.
