- the transmitter of the terminal device transmits a signal
- the receiver receives the signal at the same time, and the signal transmitted by the terminal device is the same frequency as the received signal, the signal transmitted by the terminal device may receive the same-frequency signal to the terminal device. Interference occurs, which can be called self-interference.
- self-interference can be divided into three types: harmonic interference, harmonic mixing interference, and intermodulation interference.
- Each type of self-interference can also be subdivided into smaller granularity types.
- intermodulation interference when the order of the intermodulation signals is different, it can be divided into different types of interference.
- harmonic interference when the frequency multiplication of the signal is different when harmonic interference occurs, it can be divided into different types of interference.
- the frequency of a certain order intermodulation signal (IM, intermodulation) of the uplink carrier of F1 and the uplink carrier of F2 overlaps or partially overlaps with the downlink signal frequency of carrier F3.
- carriers F1 and F2 constitute intermodulation interference for F3.

- the terminal device is configured with both the LTE carrier of Band 1 and Band 7 and the NR carrier (3400-3800 MHz), if the UL of the band 7 and the UL of the NR are simultaneously transmitted, the influence of the 5th-order intermodulation generated by the terminal device affects the band 1 DL receiver sensitivity.
- the frequency multiplication of the uplink carrier of F1 overlaps or partially overlaps with the downlink signal frequency of F2. Then carrier F1 forms a harmonic interference with F2.
- the uplink of LTE Band 3 is 1710-1785 MHz, and its second-order harmonic range is 3420-3570 MHz.

Which schedules are given, and which schedules are discarded.
- the priority of the priority list may be: LTE scheduling (transmission) > NR uplink scheduling (transmission) > NR downlink scheduling (transmission).

- the above principles have the following advantages: 1. Due to the backward compatibility problem, the existing LTE base station/chip design is difficult to solve the self-interference problem, and it is reasonable to give the LTE scheduling a higher priority. 2. The general uplink scheduling consumes more terminal energy, and the terminal device needs to make more preparations for the uplink scheduling (preparing to send data). Therefore, when the NR uplink and downlink scheduling conflicts, the uplink scheduling is preferentially reserved.
- the priority of the priority list may be: NR control information uplink scheduling (transmission) (PUCCH) > NR downlink paging, System Information Block (SIB) > NR Uplink Data Scheduling (PUSCH) (Transmission) > NR Downstream Data Scheduling (PDSCH) (Transmission).
- PUCCH NR control information uplink scheduling
- SIB System Information Block
- PUSCH NR Uplink Data Scheduling
- PDSCH NR Downstream Data Scheduling
- the terminal device selects the scheduling/transmission of priority reservation in the above-described order. Since the PUCCH is generally the most important information for transmission, its priority is the highest; the downstream paging/SIB has a certain period, and once the terminal device is missed, it needs to wait for a certain time, so it also needs a higher priority; the PUSCH has a higher priority than the PDSCH. This is because the terminal needs to be more prepared for uplink scheduling/transmission.
- the terminal device determines whether the downlink communication or the uplink communication needs to be abandoned.
- the base station may directly instruct the terminal to abandon which scheduling (transmission) to avoid self-interference.
- the LTE base station schedules an uplink semi-persistent scheduling (SPS) transmission, and the NR base station performs a downlink scheduling and generates one of the uplink SPS transmissions with LTE. Collision (self-interference occurs), at this time, the NR base station can notify the terminal to abandon the transmission that generates self-interference in the LTE connection while making the downlink scheduling.
- SPS semi-persistent scheduling
- the base station can also modify the previously made scheduling that would generate self-interference. Taking the above as an example, the NR base station can instruct the terminal to use a new uplink resource (which does not generate self-interference) to transmit uplink transmission while avoiding self-interference.
- the terminal device when the terminal device abandons the downlink communication or the uplink communication, the terminal device sends a notification signaling to the network device, to indicate to abandon the downlink communication or the uplink communication.
- the notification signaling is a Non-Knowledge (NACK) signaling.
- NACK Non-Knowledge
- the notification signaling is further used to indicate scheduling information of the communication that is not discarded or the first information as shown in the foregoing method.
- the terminal device may report to the base station side. For example, after the terminal device abandons a certain downlink scheduling, the terminal device may send NACK signaling to the base station; after the terminal abandons an uplink transmission, the terminal may send a signaling to the base station to notify the base station, such as a predefined PUCCH format.
- the terminal device may also notify the base station to generate interference scheduling information, for example, the terminal abandons a certain downlink scheduling, and the terminal notifies the base station to generate interference uplink scheduling information.

应理解,本文中术语“***”和“网络”在本文中常被可互换使用。本文中术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
可选地,终端设备的发射机在发射信号时,如果接收机同时在接收信号,且终端设备发射的信号与接收的信号同频,则终端设备发射的信号会对终端设备接收的同频信号产生干扰,此种现象可以称为自干扰。
可选地,自干扰可以分为谐波干扰、谐波混频干扰和互调干扰三种类型。每种类型的自干扰还可以细分更小粒度的类型,例如,对于互调干扰而言,互调信号的阶数不同时,可以分为不同类型的干扰。例如,对于谐波干扰而言,谐波干扰时信号的倍频不同时,可以分为不同类型的干扰。
以下以终端设备同时工作在载波F1和载波F2进行举例说明自干扰的几种类型,其中,假设载波F1工作在低频段,载波F2工作在高频段。
在一种可能中,F1的上行载波和F2的上行载波的某阶互调信号(IM,intermodulation)的频率与载波F3的下行信号频率重叠或部分重叠。那么载波F1和F2就对F3构成了互调干扰。这里F3可能是载波F1或F2中某一个,或是不同于F1/F2的另一个载波(此时,终端设备同时工作在两个以上的载波)。
例如,终端设备同时配置了Band 1和Band 7的LTE载波,NR载波(3400-3800MHz),则如果band 7的UL和NR的UL同时传输,其产生的5阶互调影响会影响band 1的DL接收机灵敏度。
在一种可能中,F1的上行载波的倍频与F2的下行信号频率重叠或部分重叠。那么载波F1对F2就构成了谐波(harmonic)干扰。
例如,LTE Band 3的上行1710-1785MHz,其2阶谐波范围为3420-3570MHz。则一个终端如果同时在band 3上进行LTE上行传输和在
NR频段3400-3800MHz上进行DL接收,则2阶谐波可能会干扰NR的DL接收机的灵敏度。
在一种可能中,F1的下行载波的倍频与F2的上行信号频率(及其邻近频率)重叠或部分重叠。那么载波F2对F1就构成了谐波混频(harmonic mixing)干扰。
例如,LTE Band 3的下行1805-1880MHz,其2阶谐波范围为3610-3760MHz。则一个终端如果同时在band 3上进行LTE下行接收和在NR频段3400-3800MHz上进行上行发送,则NR的2阶谐波混频可能会干扰LTE的DL接收机的灵敏度。
为了尽量避免自干扰,本申请实施例提供了以下的方法和装置。
图2是根据本申请实施例的无线通信方法200的示意性流程图。该方法200可选地可以应用于图1所示的***,但并不限于此。如图2所示,该方法200包括以下至少部分内容。
在210中,终端设备确定第一信号和第二信号对该终端设备产生自干扰或具有产生自干扰的可能,其中,该第一信号为该第一终端设备与第一网络设备之间利用第一载波传输的信号,该第二信号为该终端设备和与第二网络设备之间利用第二载波传输的信号。

该第一信息还用于指示:该多个网络设备中非该第一信息的接收端的其他网络设备利用对应的该第一载波进行信号传输的情况。
例如,该第一信号包括通过载波F1与基站1通信的上行信号,该第二信号包括通过载波F2与基站2通信的上行信号,第二信号为通过载波F3与基站3通信的下行信号,F1承载的信号与F2承载的信号五阶互调信号对载波F3承载的下行信号的接收造成干扰,则终端设备可以向基站1发送第一信息,该第一信息指示终端设备利用载波3与基站3进行信号传输的情况,以及指示终端设备利用载波2与基站2进行信号传输的情况。

可选地,该第一网络设备为NR***中的网络设备,该第二网络设备为
LTE***中的网络设备;或,该第一网络设备为NR***中的网络设备,该第二网络设备为LTE***中的网络设备。
当然,第一网络设备也可以是LTE中的网络设备,第二网络设备为LTE***中的网络设备;或者,第一网络设备为LTE中的网络设备,第二网络设备为NR***中的网络设备。
以下将结合几种方式,描述终端设备如何判断第一信号与第二信号是否对该终端设备产生自干扰或具有产生自干扰的可能。
在一种实现方式中,该终端设备根据预设列表,确定该第一信号与该第二信号对该终端设备产生自干扰或具有产生自干扰的可能,该预设列表用于指示多个频段之间的自干扰情况。
其中,该预设列表可以是根据协议预设的,例如,可以出厂时预设在终端设备中。
由于这种自干扰是终端设备内部产生,而一个终端设备在设计时,所支持的频段就已经知道,那么哪些频段之间存在互干扰以及互干扰严重程度可以是在终端被制造时就已经被设置在终端内部。
或者,该预设列表可以是网络设备通过广播消息预设在终端设备上的。该预设列表可以指示与该网络设备自身的频段有关的自干扰情况。
可选地,该预设列表用于指示:产生自干扰或具有产生自干扰的可能的频段组合。
或者,该预设列表用于指示:产生自干扰或具有产生自干扰的可能的频段组合,被干扰或可能被干扰的频率范围。
或者,该预设列表用于指示:产生自干扰或具有产生自干扰的可能的频段组合,被干扰或可能被干扰的频率范围,以及干扰种类。
或者,该预设列表用于指示:产生自干扰或具有产生自干扰的可能的频段组合,干扰种类。
或者,该预设列表用于指示:干扰种类,被干扰或可能被干扰的频率范围。
在以上的可选方式中,产生自干扰或具有产生自干扰的可能的频段组合可以多个上行频段与一个下行频段的组合,此时,产生的干扰种类可以是互调干扰,其中,互调干扰的种类还可以细分为产生干扰的互调信号的阶数,以及,被干扰或可能被干扰的频率范围可以是该一个下行信号频段中的小块
频段。
在以上的可选方式中,产生自干扰或具有产生自干扰可能的频段组合可以是一个上行频段与一个下行频段的组合,此时,产生干扰的种类可以是谐波干扰或谐波混频干扰,被干扰或可能被干扰的频率范围可以是该一个下行信号频段中的小块频段。
可选地,产生自干扰或具有产生自干扰的可能的频段组合中的频段信息包含具体频率起始/终止位置信息。
可选地,被干扰或可能被干扰的频率范围包含具体的频率起始/终止位置。
可选地,产生自干扰或具有产生自干扰的可能的频段组合可以区分上行频段或下行频段,例如,某一上行频段与下行频段的组合可以产生自干扰。
可选地,产生自干扰或具有产生自干扰的可能的频段组合可以不区分上行以及下行,例如,某一频段与另一频段的组合可以产生自干扰。
可选地,产生自干扰或具有产生自干扰的可能的频段组合可以区分上行,但不区分下行,例如,某一频段与某一上行频段的组合可以产生自干扰。
可选地,产生自干扰或具有产生自干扰的可能的频段组合可以不区分上行,但区分下行,例如,某一下行频段与某一频段的组合可以产生自干扰。
在另一种实现方式中,该终端设备通过该第一载波所占的频段和该第二载波所占的频段之间的数值关系,确定该第一信号与该第二信号对该终端设备产生自干扰或具有产生自干扰的可能。
例如,对于谐波干扰而言,当一个在低频的发射信号的倍频落在高频的接收带宽内,就会产生干扰,而且倍频的次数越低,干扰越严重。所以终端设备是可以基于这样的计算获得可能产生干扰的信息。
例如,对于互调干扰而言,当多个上行信号的多阶互调落在接收带宽内,就会产生干扰。所以终端设备是可以基于这样的计算获得可能产生干扰的信息。
可选地,网络设备也可以配置当干扰严重到一定程度时,终端设备才将其列为会产生自干扰的频段组合。以上述谐波干扰为例,假设网络设备可以配置5倍谐波以内的干扰才被认为能构成自干扰,如果两个频段间有6阶谐波干扰,那终端设备就可以认为这两个频段间没有自干扰。
在另一种实现方式中,该终端设备通过干扰检测的方式,确定该第一信
号与该第二信号对该终端设备产生自干扰。
由于这种自干扰是终端设备内部产生,而一个终端设备在设计时,所支持的频段就已经知道,那么哪些频段之间存在互干扰以及互干扰严重程度也可以是被终端自身测量获得。
在220中,该终端设备向该第一网络设备发送第一信息,该第一信息用于指示该第一信号与该第二信号对该终端设备产生自干扰或具有产生自干扰的可能,且指示该终端设备与该第二网络设备之间利用该第二载波进行信号传输的情况。
可选地,终端设备可以根据上述方法获得能够产生自干扰的频段组合,当终端目前工作在该频段组合包括的至少两个频段上,如果至少一个频段是NR的频段,则终端需要向NR的基站(gNB)汇报此终端可能产生自干扰。
可选地,该第一信息具体用于指示以下中的至少一种:该终端设备与该第二网络设备之间利用该第二载波进行通信连接的连接方式;该第二信号对该第一信号产生干扰或可能产生干扰的频率的信息,和/或该第二信号被该第一信号干扰或可能被干扰的频率的信息;该终端设备与该第二网络设备之间利用该第二载波进行通信的双工信息;该第二网络设备对该终端设备在第二载波上进行调度的调度信息。
可选地,该第二信号对该第一信号产生干扰或可能产生干扰的频率可以进行上行或下行的区分,或者不存在上行或下行的区分。
可选地,该第二信号被该第一信号干扰或可能被干扰的频率可进行上行或下行的区分,或者不存在上行或下行的区分。
可选地,该连接方式为双连接方式或独立连接方式。
其中,独立连接方式可以意味着终端设备与各个网络设备的连接是相互独立的,网络设备之间针对与终端设备的通信是没有信息交互的。
双连接方式可以意味着终端设备与各个网络设备的连接不是独立的,网络设备之间针对与终端设备的通信可以存在信息交互。可选地,双连接也可以称为多连接。
可选地,该双工信息包括双工方式和/或该双工方式的配置信息。
其中,该双工方式可以是时分双工(Time Division Duplexing,TDD)或频分双工(Frequency Division Duplexing,FDD)。
可选地,在双工方式为TDD时,该双工信息可以包括TDD的配置信息。
可选地,该调度信息包括上行调度信息和/或下行调度信息。
可选地,该上行调度信息包括以下中的至少一种:
上行控制信道所在的时频资源、上行数据信道所在的时频资源、上行半静态传输的周期、上行半静态传输配置的时频资源和上行传输的发射功率。
可选地,通过向第一网络设备上报终端设备与第二网络设备之间利用第二载波进行的上行传输所占用的时频资源,可以使得第一网络设备调度的下行传输不落入该上行传输所造成的干扰频率范围内。
可选地,由于上行传输的发射功率较小时,对下行接收造成干扰的可能性较小,或者造成的干扰较小,因此,通过向第一网络设备上报终端设备与第二网络设备之间利用第二载波进行的上行传输所用的发射功率,可以使得第一网络设备判断第一网络设备调度的下行传输是否被第一网络设备调度的上行传输所干扰。
可选地,该上行调度信息包括以下中的至少一种:
下行控制信道所在的时频资源、下行数据信道所在的时频资源、下行半静态传输的周期、下行半静态传输配置的时频资源和下行传输所采用的调制与编码策略(Modulation and Coding Scheme,MCS)。
可选地,通过向第一网络设备上报终端设备与第二网络设备之间利用第二载波进行的下行传输所占用的时频资源,可以使得第一网络设备调度的上行传输避免对该上行传输造成干扰。
可选地,由于下行传输的MCS等级较低时,对上行传输引起的干扰的容忍度较大,因此,通过向第一网络设备上报终端设备与第二网络设备之间利用第二载波进行的下行传输所用的MCS,可以使得第一网络设备判断第一网络设备调度的上行传输是否对第一网络设备调度的上行传输造成干扰。
可选地,在第二信号为上行信号时,可以向第一网络设备发送第二信号的上行调度信息;也可以向第一网络设备发送第二信号的上行调度信息,以及上报终端设备与第二网络设备通过第二载波传输的下行信号的调度信息。
可选地,在第二信号为下行信号时,可以向第一网络设备发送第二信号的下行调度信息;也可以向第一网络设备发送第二信号的下行调度信息,以及上报终端设备与第二网络设备通过第二载波传输的上行信号的调度信息。
因此,在本申请实施例中,终端设备确定第一信号(所述终端设备与第一网络设备之间利用第一载波传输的信号)和第二信号(所述终端设备和与
第二网络设备之间利用第二载波传输的信号)对所述终端设备产生自干扰或具有产生自干扰的可能时,所述终端设备向所述第一网络设备发送第一信息,所述第一信息用于指示所述第一信号与所述第二信号对所述终端设备产生自干扰或具有产生自干扰的可能,且指示所述终端设备与所述第二网络设备之间利用所述第二载波进行信号传输的情况,可以使得第二网络设备避免对该终端设备调度的信号传输对第一网络设备对终端设备调度的信号传输造成干扰,或者,使得第二网络设备避免对终端设备调度的信号传输被第一网络设备对终端设备调度的信号传输所干扰。
图3是根据本申请实施例的无线通信方法300的示意性流程图。该方法300可以包括以下内容中的至少部分内容。
在310中,第一网络设备接收终端设备发送的第一信息,该第一信息用于指示第一信号与第二信号对该终端设备产生自干扰或具有产生自干扰的可能,且指示该终端设备与第二网络设备之间利用第二载波进行第二信号的传输的情况,其中,该第一信号为该第一终端设备与第一网络设备之间利用第一载波传输的信号,该第二信号为该终端设备和与第二网络设备之间利用第二载波传输的信号。
在320中,根据该第一信息,该第一网络设备对该终端设备进行配置,和/或与该第二网络设备协商该第二网络设备对该终端设备的配置。
可选地,该第一信息具体用于指示以下中的至少一种:
该终端设备与该第二网络设备之间利用该第二载波进行通信连接的连接方式;
该第二信号对该第一信号产生干扰或可能产生干扰的频率的信息,和/或该第二信号被该第一信号干扰或可能被干扰的频率的信息;
该终端设备与该第二网络设备之间利用该第二载波进行通信的双工信息;
该第二网络设备在第二载波上对该终端设备进行调度的调度信息。
可选地,该连接方式为双连接方式或独立连接方式。
可选地,该双工信息包括双工方式和/或该双工方式的配置信息。
可选地,该调度信息包括上行调度信息和/或下行调度信息。
可选地,该上行调度信息包括以下中的至少一种:上行控制信道所在的时频资源、上行数据信道所在的时频资源、上行半静态传输的周期、上行半
静态传输配置的时频资源和上行传输的发射功率。
可选地,该下行调度信息包括以下中的至少一种:下行控制信道所在的时频资源、下行数据信道所在的时频资源、下行半静态传输的周期、下行半静态传输配置的时频资源和下行传输所采用的MCS。
为了便于理解,以下将结合几种实现方式描述如何根据该第一信息,该第一网络设备对该终端设备进行配置,和/或与该第二网络设备协商该第二网络设备对该终端设备的配置。
在一种实现方式中,网络设备可以根据不同的干扰类型决定不同的调度策略以避免干扰。
例如,如果LTE***中的上行信号对NR***中的下行信号产生了干扰,NR***中的基站将根据终端设备汇报的LTE的上行调度信息,不在受干扰的下行时频区域内对终端设备进行下行调度。
例如,如果NR***中的上行对LTE***中的下行信号产生了干扰,NR***中的基站将根据终端设备汇报的LTE的下行调度信息,至少调度NR***的上行信号不干扰LTE的控制信道。NR基站还可以通过控制NR上行发射功率的方法,减少对LTE PDSCH的干扰。
在一种实现方式中,该第二网络设备与该终端设备的双工方式为具有第一配置的TDD;该第一网络设备与该终端设备的之间利用该第一载波进行的传输的双工方式配置为具有第一配置的TDD方式。
例如,当一个LTE连接与一个NR连接产生互干扰,而且此LTE连接是一个TDD连接,则NR基站可以依据终端设备的汇报,将针对此终端设备的NR连接配置为和产生干扰的LTE连接一样的TDD配置。这样从终端设备的角度,LTE与NR连接就处于同步收发的状态,从而可以避免自干扰问题。
可选地,该第二网络设备与该终端设备的双工方式为FDD;该第一网络设备与该第二网络设备协商,将该第二网络设备与该终端设备之间通过该第二载波的连接配置为半双工方式,且,协商该第一网络设备与该第二网络设备分别利用该第一载波和该第二载波与该终端设备之间的传输状态为同步收发状态。
例如,当一个有LTE与NR双连接(dual connectivity)的终端设备,当LTE连接与NR连接产生互干扰,且LTE连接的双工方式是FDD。NR基站可以
协调LTE基站,将此终端的FDD LTE连接配置为半双工模式(收发不同时),且配置NR连接为与LTE连接同步收发状态,从而可以避免自干扰。
依据上述方法,基于终端设备向网络设备的汇报,网络设备是可能通过合理的调度解决自干扰问题的。但是在实际中,网络设备可能很难完全避免在调度中出现自干扰问题。譬如,在NR***中,调度的周期可能远远小于LTE的调度周期,这时,即使终端设备汇报了自干扰信息,自干扰可能已经无法避免(NR***的网络设备可能在收到终端设备对LTE调度信息有关的自干扰的汇报前,已经作好调度了),此时需要一定的机制使得当NR/NR或NR/LTE的网络设备做出了相互干扰(自干扰)的调度后,终端设备可以避开上述自干扰。
应理解,以下实施例中的方法,终端设备可以上报如上方式所示的自干扰相关信息,也可以不上报。也即以下的方法和以上的方法可以结合使用,也可以独立存在。
图4是根据本申请实施例的无线通信方法800的示意性流程图。该方法800包括以下内容中的至少部分内容。
在810中,终端设备在不同的载波需要同时进行下行通信和上行通信时,确定是否需要放弃下行通信或上行通信。
在一种实现方式中,该终端设备确定该下行通信和该上行通信是否产生自干扰;根据该下行通信和该上行通信是否产生自干扰,该终端设备确定是否需要放弃下行通信或上行通信。
可选地,根据该下行通信的频段与该上行通信的频段的组合或当前时间,该终端设备确定该下行通信和上行通信是否产生自干扰。
具体地,根据当前时间,以及结合网络设备配置的不产生自干扰的时间段,该终端设备确定该下行通信和上行通信是否产生自干扰。
或者,该终端设备根据该下行通信的频段与该上行通信的频段的组合,以及结合网络设备配置的不产生自干扰的频段组合或可能产生自干扰的频段组合,确定该下行通信和该上行通信是否产生自干扰。
具体地,网络设备可以指示终端设备该终端设备被调度的上下行资源是否存在潜在的自干扰问题。这样指示的好处是,如果网络设备在调度终端设备时就不使用可能带来干扰的频率资源,终端设备就不必每次接到调度后还要判断这些调度是否会导致自干扰。进一步网络设备还可以指示终端设备
可能被调度的频段范围,包括上下行频段范围,如果这些上下行频段就不会存在潜在的自干扰,那终端也可以获知之后的调度不存在潜在的自干扰。进一步网络还可以指示终端可能被调度的频段范围,包括上下行频段范围,如果这些上下行频段就不会存在潜在的自干扰,那终端也可以获知之后的调度不存在潜在的自干扰。
或者,网络设备在确定不产生自干扰的频段组合时,可以确定在该组合上调度终端设备的持续时间,网络设备可以利用该不产生自干扰的组合对终端设备进行调度,终端设备在该持续时间内针对该网络设备的调度不进行自干扰的判断。
可选地,上述指示既可以是广播信令,针对一组终端或一个小区内所有终端;也可以是终端专用(UE-specific)信令,针对某个特定终端。
在820中,在需要放弃下行通信或上行通信时,该终端设备放弃下行通信或上行通信。
可选地,根据通信的优先级信息,确定该下行通信和该上行通信中需要放弃的通信;该终端设备放弃确定的该需要放弃的通信。
该优先级信息指示:
LTE***中的通信的优先级高于新无线***中的优先级;和/或,
上行通信的优先级高于下行通信的优先级;和/或,
传输控制信息的通信的优先级高于传输数据的通信的优先级;和/或,
两次通信的间隔时间长的通信的优先级高于两次通信的间隔时间短的通信的优先级。
在一种实现方式中,该优先级信息用于指示:
LTE***中的通信的优先级高于NR***中的上行通信的优先级;以及
NR***中的上行通信的优先级高于NR***中的下行通信。
在一种实现方式中,该优先级信息用于以下:
物理上行控制信道(Physical Uplink Control Channel,PUCCH)的传输的优先级高于NR***中的下行寻呼或***信息传输的优先级;NR***中的下行寻呼或***信息传输的优先级高于NR***的物理上行共享信道(Physical Uplink Shared Channel,PUSCH)的传输的优先级;以及NR***的PUSCH的传输的优先级高于NR***中的物理下行共享信道(Physical Downlink Shared Channel,PDSCH)的传输。
具体地,基站可以预先为终端设备配置一个优先级列表,这个列表可以是通过广播形式配置(配置一组终端或是一个小区内的终端),也可以是通过UE-specific信令的形式配置单个终端。上述优先级列表规定了当终端设备接到了能导致自干扰的调度时(一个载频/载波的上行调度,对另一个载频/载波的下行调度构成干扰),终端设备可以按优先级选择执行哪些调度,同时放弃哪些调度。
例如,该优先级列表的优先级从高到低可以是:LTE调度(传输)>NR上行调度(传输)>NR下行调度(传输)。其中,本申请实施例提到的优先级较高是指较重要,不轻易放弃的通信。
上述列表的含义可以如下,当终端设备接到能导致自干扰的LTE和NR调度时,终端设备优先保留LTE调度,而放弃NR调度;而当终端设备接到能导致自干扰的NR调度时,终端设备优先保留NR上行调度,而放弃NR下行调度。采用上述原则有如下好处:1.由于后向兼容性的问题,已有的LTE基站/芯片设计很难去解决自干扰问题,这时给予LTE调度更高的优先级是合理的。2.一般上行调度更消耗终端能量,而且终端设备需要为上行调度做出更多的准备(准备发送数据),所以当NR上下行调度出现冲突时,优先保留上行调度。
再例如,该优先级列表的优先级从高到低是可以是:NR控制信息上行调度(传输)(PUCCH)>NR下行寻呼(paging),***信息调度(System Information Block,SIB)>NR上行数据调度(PUSCH)(传输)>NR下行数据调度(PDSCH)(传输)。
上述列表的含义如下,当在终端设备发生能导致自干扰的NR上行和下行调度(传输)时,终端设备按照上述次序选择优先保留的调度/传输。由于PUCCH一般是传输比较重要的信息,其优先级最高;下行paging/SIB是有一定周期的,一旦错过终端设备需要等待一定时间,所以也需要较高的优先级;PUSCH的优先级高于PDSCH是由于终端需要为上行调度/传输做出更多的准备。
可选地,根据所述网络设备指示的需要放弃的通信,终端设备确定是否需要放弃所述下行通信或上行通信。
具体地,除了采用优先级列表的方式让终端设备选择保留的调度/传输,基站也可以直接指示终端放弃哪些调度(传输),以避免自干扰。譬如,当
一个终端在LTE+NR双连接时,LTE基站调度了一个上行半静态调度(Semi-Persistent Scheduling,SPS)传输,而NR基站要作一个下行调度,并且与LTE的上行SPS传输中的某一次产生冲突(发生自干扰),这时NR基站在做出下行调度的同时,可以通知该终端放弃LTE连接中产生自干扰的那次传输。除了可以通知终端放弃调度/传输,以避免自干扰,基站还可以修改之前做出的会产生自干扰的调度。还以上述为例,NR基站可以在下行调度的同时,指示终端使用一个新的上行资源(不会产生自干扰)的发送上行传输,以避免自干扰。
可选地,终端设备在放弃该下行通信或上行通信时,该终端设备向网络设备发送通知信令,用于指示放弃该下行通信或该上行通信。
可选地,在放弃的为该下行通信时,该通知信令为否定确认(Non-Knowledge,NACK)信令。
可选地,该通知信令还用于指示未放弃的通信的调度信息或者如上述方法所示的第一信息。
具体地,当终端设备按照上述优先级列表放弃了某个调度(传输)时,终端设备可以向基站侧汇报。譬如当终端设备放弃了某下行调度后,终端设备可以向基站发送NACK信令;当终端放弃了某上行传输后,终端可以向基站发送信令通知基站,譬如某预先定义的PUCCH格式。
可选的,终端设备在通知基站放弃某调度(传输)时,也可以通知基站产生干扰的调度信息,譬如终端放弃某下行调度,终端通知基站产生干扰的上行调度信息。
可选地,在放弃该下行通信或上行通信,重新执行放弃的该下行通信或该上行通信。
具体地,根据该网络设备的调度,终端设备重新执行该下行通信或该上行通信。
因此,在本申请实施例中,终端设备在不同的载波同时进行下行通信和上行通信时,确定是否需要放弃下行通信或上行通信;在需要放弃下行通信或上行通信时,所述终端设备放弃下行通信或上行通信,可以避免自干扰的产生。
