Description

无线通信方法、终端设备和网络设备Wireless communication method, terminal device and network device 技术领域technical field
本申请实施例涉及通信领域，并且更具体地，涉及一种无线通信方法、终端设备和网络设备。The embodiments of the present application relate to the field of communication, and more particularly, to a wireless communication method, terminal device, and network device.
背景技术Background technique
在新空口(New Radio，NR)中，网络设备可以为终端设备配置非连续接收(Discontinuous Reception，DRX)，使得终端设备可以在DRX激活期(DRX Active Time)监听物理下行控制信道(Physical Uplink Control Channel，PDCCH)。其中，网络设备为终端设备配置的DRX配置信息包括：定时器drx-HARQ-RTT-TimerUL和drx-RetransmissionTimerUL。In the new air interface (New Radio, NR), the network device can configure Discontinuous Reception (DRX) for the terminal device, so that the terminal device can monitor the physical downlink control channel (Physical Uplink Control Channel) during the DRX Active Time (DRX Active Time). Channel, PDCCH). The DRX configuration information configured by the network device for the terminal device includes timers drx-HARQ-RTT-TimerUL and drx-RetransmissionTimerUL.
在上行混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)中，终端设备在完成物理上行共享信道(Physical Uplink Shared Channel，PUSCH)的第一次重复传输(repetition)之后，启动HARQ进程对应的定时器drx-HARQ-RTT-TimerUL，并且定时器drx-HARQ-RTT-TimerUL超时后，终端设备启动该HARQ进程对应的定时器drx-RetransmissionTimerUL，该drx-HARQ-RTT-TimerUL的时间长度与终端设备与网络设备之间的往返时间(Round-Trip Time，RTT)相关。由此可知，网络设备将基于PUSCH解码结果，决定是否调度初传或者重传，终端设备将至少等待一个终端设备与网络设备之间的RTT，才能收到初传或者重传的调度指示。In the uplink hybrid automatic repeat request (HARQ), the terminal device starts the timing corresponding to the HARQ process after completing the first repetition of the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH). After the timer drx-HARQ-RTT-TimerUL, and the timer drx-HARQ-RTT-TimerUL times out, the terminal device starts the timer drx-RetransmissionTimerUL corresponding to the HARQ process. The time length of the drx-HARQ-RTT-TimerUL is the same as that of the terminal device. It is related to the round-trip time (RTT) between network devices. It can be seen that the network device will decide whether to schedule initial transmission or retransmission based on the PUSCH decoding result, and the terminal device will wait for at least one RTT between the terminal device and the network device before receiving the scheduling instruction of the initial transmission or retransmission.
而在非地面通信网络(Non-Terrestrial Network，NTN)网络中，其RTT远远大于地面通信网络(Terrestrial Network，TN)的RTT。因此，如果在NTN中仍然采用目前这种DRX配置，势必造成上行数据传输效率低的问题。In a non-terrestrial network (Non-Terrestrial Network, NTN) network, the RTT is much larger than the RTT of a terrestrial network (Terrestrial Network, TN). Therefore, if the current DRX configuration is still adopted in NTN, it will inevitably cause the problem of low transmission efficiency of uplink data.

For example, general terrestrial communication cannot cover areas such as oceans, mountains, deserts, etc. where communication equipment cannot be set up or cannot be covered due to sparse population. For satellite communication, due to a single Satellites can cover a large ground, and satellites can orbit around the earth, so theoretically every corner of the earth can be covered by satellite communications. Secondly, satellite communication has great social value.

The signal propagation delay of single-hop communication between users is generally less than 20ms. The maximum satellite viewing time is 20 minutes. The signal propagation distance is short, the link loss is small, and the transmit power requirements of the user terminal are not high.
GEOGEO
地球同步轨道卫星，轨道高度为35786km，围绕地球旋转周期为24小时。用户间单跳通信的信号传播延迟一般为250ms。A satellite in geosynchronous orbit with an orbital altitude of 35,786km and a 24-hour rotation period around the earth. The signal propagation delay of single-hop communication between users is generally 250ms.
为了保证卫星的覆盖以及提升整个卫星通信***的***容量，卫星采用多波束覆盖地面，一颗卫星可以形成几十甚至数百个波束来覆盖地面；一个卫星波束可以覆盖直径几十至上百公里的地面区域。In order to ensure the coverage of satellites and improve the system capacity of the entire satellite communication system, satellites use multiple beams to cover the ground. A satellite can form dozens or even hundreds of beams to cover the ground; a satellite beam can cover tens to hundreds of kilometers in diameter. ground area.

The terminal device starts the drx-HARQ-RTT-TimerUL corresponding to the HARQ process after completing the first repeated transmission of the PUSCH (ie, HARQ retransmission). If the timer drx-HARQ-RTT-TimerUL times out, the terminal device starts the drx-RetransmissionTimerUL corresponding to this HARQ process.
如上所述，drx-HARQ-RTT-TimerUL的时间长度与终端设备与网络设备之间的RTT相关。由此可知，网络设备将基于PUSCH解码结果，决定是否调度初传或者重传，终端设备将至少等待一个终端设备与网络设备之间的RTT，才能收到初传或者重传的调度指示。而在NTN网络中，其RTT远远大于TN的RTT。因此，如果在NTN中仍然采用目前这种DRX配置，势必造成上行数据传输效率低的问题。As mentioned above, the time length of drx-HARQ-RTT-TimerUL is related to the RTT between the terminal device and the network device. It can be seen that the network device will decide whether to schedule initial transmission or retransmission based on the PUSCH decoding result, and the terminal device will wait for at least one RTT between the terminal device and the network device before receiving the scheduling instruction of the initial transmission or retransmission. In the NTN network, the RTT is much larger than that of the TN. Therefore, if the current DRX configuration is still adopted in NTN, it will inevitably cause the problem of low transmission efficiency of uplink data.
为了解决这一技术问题，在本申请中，网络设备可以为终端设备配置如下定时器，该定时器是为在RTT内提前接收上行调度授权而设置的定时器。In order to solve this technical problem, in this application, the network device may configure the following timer for the terminal device, where the timer is a timer set for receiving an uplink scheduling grant in advance within the RTT.

应理解，本文中术语“***”和“网络”在本文中常可互换使用。It should be understood that the terms "system" and "network" are often used interchangeably herein.
应理解，在NTN中，由于NTN中的RTT远远大于NR中的RTT，且上行HARQ进程数量无法相应大幅度增加，现有HARQ机制有HARQ进程阻塞(HARQ stalling)，即所有上行HARQ进程对应的定时器drx-HARQ-RTT-TimerUL都处于运行状态，而没有空闲的上行HARQ进程可用于上行传输的问题。为了实现NTN***连续的数据传输、提高吞吐量，当前标准中讨论了“禁用上行HARQ重传(disabling UL HARQ retransmission)”。因此，本申请实施例中的终端设备可以是这种禁用上行HARQ重传的终端设备，本申请对此不做限制。It should be understood that in NTN, since the RTT in NTN is much larger than the RTT in NR, and the number of upstream HARQ processes cannot be greatly increased accordingly, the existing HARQ mechanism has HARQ process blocking (HARQ stalling), that is, all upstream HARQ processes correspond to The timers drx-HARQ-RTT-TimerUL are all running, and there is no problem that idle uplink HARQ processes are available for uplink transmission. In order to realize continuous data transmission in the NTN system and improve throughput, "disabling UL HARQ retransmission" is discussed in the current standard. Therefore, the terminal device in this embodiment of the present application may be such a terminal device for which uplink HARQ retransmission is disabled, which is not limited in the present application.

During the running period of the first timer, the terminal device is in the DRX activation period, that is, during the running period of the first timer, the terminal device can monitor the first PDCCH.

This application will not repeat this.
可选的，在PUSCH(即HARQ重传)的第一次重复传输的结束时间，终端设备可以启动第一定时器。在该第一定时器运行期间，终端设备监听第一PDCCH，以获取提前的上行调度授权，并根据该提前的上行调度授权进行上行数据传输。Optionally, at the end time of the first repeated transmission of the PUSCH (ie, HARQ retransmission), the terminal device may start the first timer.

The second timer is used to set the minimum waiting time that the terminal device expects to receive a non-advanced uplink scheduling grant in the second PDCCH. That is, the second timer here is the standard timer drx-HARQ-RTT-TimerUL.
应理解，在当前标准中，并未提及提前的上行调度授权，因此，当前标准中，第二定时器的定义是：终端设备期望接收到指示上行HARQ重传调度的PDCCH需要的最少等待时间。而在本申请中，为了区分提前和非提前的上行调度授权，对第二定时器的定义有所调整，但其实际意义与当前标准中的实际意义相同。It should be understood that in the current standard, the advance uplink scheduling grant is not mentioned. Therefore, in the current standard, the definition of the second timer is: the minimum waiting time that the terminal device expects to receive the PDCCH indicating the uplink HARQ retransmission scheduling . In this application, the definition of the second timer is adjusted in order to distinguish the early and non-advanced uplink scheduling grants, but its actual meaning is the same as that in the current standard.
应理解，在本申请中，由于上行调度授权应用在HARQ重传场景，因此，指示上行HARQ重传调度的PDCCH即为上述携带上行调度授权的PDCCH。It should be understood that in this application, since the uplink scheduling grant is applied in the HARQ retransmission scenario, the PDCCH indicating the uplink HARQ retransmission scheduling is the above-mentioned PDCCH carrying the uplink scheduling grant.

应理解，在本申请中，第一PDCCH与第二PDCCH的不同之处在于，第一PDCCH携带的是提前的上行调度授权，而第二PDCCH携带的是非提前的上行调度授权。It should be understood that, in this application, the difference between the first PDCCH and the second PDCCH is that the first PDCCH carries an advance uplink scheduling grant, while the second PDCCH carries a non-advanced uplink scheduling grant.
需要说明的是，上述第一定时器、第二定时器和第三定时器对应同一HARQ进程，它们也可以被称为HARQ进程对应的第一定时器、HARQ进程对应的第二定时器和HARQ进程对应的第三定时器。It should be noted that the above-mentioned first timer, second timer and third timer correspond to the same HARQ process, and they may also be referred to as the first timer corresponding to the HARQ process, the second timer corresponding to the HARQ process, and the HARQ process. The third timer corresponding to the process.
如上所述，NTN中的RTT远远大于NR中的RTT，因此，为了适配NTN中的RTT，本申请针对第二定时器引入相关的时间偏置，具体通过如下示例进行说明：As mentioned above, the RTT in NTN is much larger than the RTT in NR. Therefore, in order to adapt to the RTT in NTN, the present application introduces a related time offset for the second timer, which is explained by the following example:
示例1：图4为本申请实施例提供的各个定时器的一种时间关系示意图，如图4所示，在PUSCH的第一次重复传输的结束时间，终端设备可以启动第一定时器。终端设备以PUSCH的第一次重复传输的结束时间为起始时间，在第一时间偏置之后，启动第二定时器。即第一定时器和第二定时器的启动时间的时间间隔为第一时间偏置。而在第二定时 器超时时，终端设备可以启动第三定时器。Example 1: FIG. 4 is a schematic diagram of a time relationship of timers provided in this embodiment of the application. As shown in FIG. 4 , at the end time of the first repeated transmission of the PUSCH, the terminal device may start the first timer. The terminal device takes the end time of the first repeated transmission of the PUSCH as the start time, and starts the second timer after the first time offset.

可选的，若终端设备在第一PDCCH内接收到提前的上行调度授权，且第二定时器处于未启动状态，则终端设备停止第一定时器。若终端设备在第一PDCCH内接收到提前的上行调度授权，且第二定时器处于运行状态，则停止第一定时器和第二定时器。若终端设备在第二PDCCH内接收到非提前的上行调度授权，则停止第三定时器。Optionally, if the terminal device receives an advance uplink scheduling grant in the first PDCCH and the second timer is in an inactive state, the terminal device stops the first timer.

If the terminal device receives a non-advanced uplink scheduling grant in the second PDCCH, the third timer is stopped.
应理解，第二定时器的默认持续时间可参照上文，本申请对此不再赘述。It should be understood that the default duration of the second timer may refer to the above, which will not be repeated in this application.

综上，本申请为第二定时器引入了相关的时间偏置，从而可以适配NTN中的RTT。并且本申请无需增加第三定时器的值域范围，终端设备在第三定时器运行期间，需要监听PDCCH，而本申请增加了上述第一时间偏置或者第二时间偏置，而在第一时间偏置或者第二时间偏置内，终端设备无需监听PDCCH，从而相对于增加第三定时器的值域范围的方法，采用本申请技术方案可以达到终端设备省电的目的。In conclusion, the present application introduces a related time offset for the second timer, so that the RTT in the NTN can be adapted. In addition, the present application does not need to increase the value range of the third timer, the terminal device needs to monitor the PDCCH during the operation of the third timer, and the present application adds the above-mentioned first time offset or second time offset. Within the time offset or the second time offset, the terminal device does not need to monitor the PDCCH, so compared with the method of increasing the value range of the third timer, the technical solution of the present application can achieve the purpose of power saving of the terminal device.
