Description

干扰抑制方法及装置、存储介质Interference suppression method and device, storage medium 技术领域Technical field
本公开涉及通信领域,尤其涉及干扰抑制方法及装置、存储介质。The present disclosure relates to the field of communications, and in particular, to interference suppression methods and devices, and storage media.
背景技术Background technique
Rel-18(Release-18,版本18)duplex enhancement(双工增强)项目中将对增强全双工方案进行研究,具体地,网络侧设备能够在一个slot(时隙)内同时进行数据的收发。In the Rel-18 (Release-18, version 18) duplex enhancement project, the enhanced full-duplex solution will be studied. Specifically, the network side device can send and receive data simultaneously within a slot (time slot). .
目前3GPP(3rd Generation Partnership Project,第3代合作伙伴计划)确定Rel-18对于全双工的增强只针对gNB(基站),而终端侧仍然只支持半双工。基站可以为增强(Division Duplex,全双工)终端在DL(DownLink,下行链路)slot内配置用于上行数据传输的UL(UpLink,上行链路)subband(子带),并在UL subband的时频范围内调度所述终端的上行数据传输。Currently, 3GPP (3rd Generation Partnership Project) has determined that Rel-18's full-duplex enhancements are only for gNBs (base stations), while the terminal side still only supports half-duplex. The base station can configure the UL (UpLink, uplink) subband (subband) for uplink data transmission in the DL (DownLink, downlink) slot for the enhanced (Division Duplex, full-duplex) terminal, and in the UL subband The uplink data transmission of the terminal is scheduled within a time-frequency range.
考虑到增强全双工能力需要在DL slot内发送上行传输,其会收到来自本基站下行传输的自干扰以及来自邻基站的下行co-channel(同频)干扰。考虑到基站下行发送的功率较高,造成的交叉时隙干扰会带来严重的干扰,极大的影响上行传输性能。如何抑制来自服务小区的自干扰以及来自邻小区的下行干扰,当前并没有明确的方案。Considering that enhancing the full-duplex capability requires sending uplink transmission within the DL slot, it will receive self-interference from the downlink transmission of this base station and downlink co-channel (co-channel) interference from neighboring base stations. Considering that the downlink transmission power of the base station is relatively high, the resulting cross-slot interference will cause serious interference and greatly affect the uplink transmission performance. There is currently no clear solution on how to suppress self-interference from the serving cell and downlink interference from neighboring cells.

双工模式增强是3GPP Rel-18研究的重要内容,其主要思想是在一个时隙内同时进行数据的收发。为了尽量减少对于终端复杂度和射频方面的影响,目前的共识是第一阶段将双工模式增强的研究限制在基站侧,也即仅在基站侧支持增强全双工,例如,Cross Division Duplex,或者xDD。Duplex mode enhancement is an important part of 3GPP Rel-18 research. Its main idea is to transmit and receive data simultaneously within a time slot. In order to minimize the impact on terminal complexity and radio frequency, the current consensus is to limit the research on duplex mode enhancement to the base station side in the first phase, that is, only support enhanced full duplex on the base station side, for example, Cross Division Duplex. Or xDD.
增强全双工系统中存在多种干扰类型,参照图1所示,包括:There are many types of interference in the enhanced full-duplex system, as shown in Figure 1, including:
来自基站上下行传输之间的self-interference(自干扰);Self-interference between uplink and downlink transmissions from the base station;
来自其他基站的gNB-to-gNB(基站间)的cross-slot interference(交叉时隙干扰);gNB-to-gNB cross-slot interference from other base stations;
来自其他终端的UE-to-UE(终端间)的cross-slot interference;UE-to-UE (inter-terminal) cross-slot interference from other terminals;
其中,来自其他基站的gNB-to-gNB的cross-slot interference较为强烈,会极大的影响增强全双工系统的传输性能。Among them, the gNB-to-gNB cross-slot interference from other base stations is relatively strong, which will greatly affect the transmission performance of the enhanced full-duplex system.
在目前的协议中,UL BWP只能在UL slot中配置。也即在DL slot中 不存在UL BWP的配置。也即当前系统中不存在如下两种干扰:In the current protocol, UL BWP can only be configured in the UL slot. That is to say, there is no UL BWP configuration in the DL slot. That is to say, there are no following two types of interference in the current system:
来自基站上下行传输之间的self-interference;来自其他基站相同载波上的gNB-to-gNB cross-slot interference。Self-interference between uplink and downlink transmissions from base stations; gNB-to-gNB cross-slot interference from other base stations on the same carrier.
在Rel-16 CLI(Cross Link Interference,交叉链路干扰)的研究中,3GPP对于动态TDD(Time Division Duplex,时分复用)场景进行了研究。研究表明,即便是adjacent(相邻)的场景下,DL-to-UL的交叉时隙干扰在绝大多数场景下会造成严重的性能恶化,从而导致不能正常工作。但是当前协议中并没有标准化干扰抑制的方法,仅是给出了应用部署动态TDD的相关建议。也即目前并没有任何关于CLI抑制的方法。In the study of Rel-16 CLI (Cross Link Interference, cross-link interference), 3GPP studied dynamic TDD (Time Division Duplex, time division multiplexing) scenarios. Research shows that even in adjacent scenarios, DL-to-UL cross-slot interference will cause serious performance deterioration in most scenarios, resulting in failure to work properly. However, there is no standardized interference suppression method in the current protocol, and only relevant suggestions for application deployment of dynamic TDD are given. That is to say, there is currently no method for CLI suppression.
为了解决上述技术问题,本公开提供了以下干扰抑制方法,可以通过协议约定义的方式,有效抑制来自服务小区或者抑制来自邻小区的下行传输对于下行时隙内用于进行上行传输的上行子带的干扰。下面先从基站侧介绍一下本公开提供的干扰抑制方法。In order to solve the above technical problems, the present disclosure provides the following interference suppression method, which can effectively suppress downlink transmission from the serving cell or from neighboring cells in a manner defined by the protocol. For the uplink subband used for uplink transmission in the downlink time slot interference. The interference suppression method provided by this disclosure is first introduced from the base station side.
第一种方式,基站来降低下行时隙内与上行频域资源相邻的下行频域资源上的下行发射功率。The first way is for the base station to reduce the downlink transmit power on the downlink frequency domain resources adjacent to the uplink frequency domain resources in the downlink time slot.
本公开实施例提供了一种干扰抑制方法,参照图2所示,图2是根据一实施例示出的一种干扰抑制方法流程图,可以由基站执行,该方法可以包括以下步骤:An embodiment of the present disclosure provides an interference suppression method. Refer to Figure 2.

Slot interference improves the reliability of uplink transmission and the feasibility of enhancing full-duplex communication.
在一些可选实施例中,参照图4所示,图4是根据一实施例示出的一种干扰抑制方法流程图,可以由基站执行,该方法可以包括以下步骤:In some optional embodiments, refer to Figure 4, which is a flow chart of an interference suppression method according to an embodiment, which can be executed by a base station. The method can include the following steps:
在步骤401中,基于协议约定,确定与不同的下行RB区间对应的不同的第二功率回退值。In step 401, based on the protocol agreement, different second power backoff values corresponding to different downlink RB intervals are determined.
在本公开实施例中,可以由协议约定不同下行RB(Resource Block,资源块)区间对应的不同的第二功率回退值。第一下行RB区间对应的所述第二功率回退值大于第二下行RB区间对应的所述第二功率回退值;其中,所述第一下行RB区间相对于上行频域资源的距离小于所述第二下行RB区间相对于所述上行频域资源的距离。In the embodiment of the present disclosure, different second power backoff values corresponding to different downlink RB (Resource Block, resource block) intervals can be agreed upon by the protocol. The second power backoff value corresponding to the first downlink RB interval is greater than the second power backoff value corresponding to the second downlink RB interval; wherein, the first downlink RB interval is relative to the uplink frequency domain resource. The distance is smaller than the distance between the second downlink RB interval and the uplink frequency domain resource.
在步骤402中,将所述第二下行发射功率与每个所述第二功率回退值的差值确定为每个所述下行RB区间对应的所述第一下行发射功率。In step 402, the difference between the second downlink transmit power and each of the second power backoff values is determined as the first downlink transmit power corresponding to each of the downlink RB intervals.
在步骤403中,基于协议约定方式,在所述下行时隙所包括的每个所述下行RB区间上,使用与所述下行RB区间对应的所述第一下行发射功 率进行下行传输。In step 403, based on the protocol agreement, on each downlink RB interval included in the downlink time slot, use the first downlink transmission power corresponding to the downlink RB interval for downlink transmission.
在本公开实施例中,可以引入功率梯度下降基站,即每个下行RB区间对应不同的第一下行发射功率。In the embodiment of the present disclosure, a power gradient descent base station may be introduced, that is, each downlink RB interval corresponds to a different first downlink transmit power.
参照图5所示,可以协议约定不同下行RB区间对应的不同第二功率回退值,第一下行RB区间对应的所述第二功率回退值大于第二下行RB区间对应的所述第二功率回退值;其中,所述第一下行RB区间相对于上行频域资源的距离小于所述第二下行RB区间相对于所述上行频域资源的距离。使得基站在远离用于进行上行传输的上行子带的下行频域资源可使用较高的第一下行发射功率进行下行传输,越接近该上行子带的下行频域资源使用较低的第一下行发射功率进行下行传输。Referring to Figure 5, different second power backoff values corresponding to different downlink RB intervals can be agreed upon by agreement, and the second power backoff value corresponding to the first downlink RB interval is greater than the second power backoff value corresponding to the second downlink RB interval. Two power backoff values; wherein the distance between the first downlink RB interval and the uplink frequency domain resource is smaller than the distance between the second downlink RB interval and the uplink frequency domain resource. This allows the base station to use a higher first downlink transmit power for downlink frequency domain resources far away from the uplink subband used for uplink transmission, and use a lower first downlink frequency domain resource closer to the uplink subband. Downlink transmit power for downlink transmission.
还需要说明的是,这里基站侧基于功率梯度下降机制调整不同下行RB对应的第一下行发射功率的方案,可以适用于终端服务小区的基站,这样终端进行下行接收时,接收到的是基站进行下行功率控制后发送的下行信息。另外还可以适用于服务小区的邻基站,从而减少来自邻基站的交叉时隙干扰。It should also be noted that the base station side here adjusts the first downlink transmit power corresponding to different downlink RBs based on the power gradient descent mechanism, which can be applied to the base station of the terminal serving cell. In this way, when the terminal performs downlink reception, what it receives is the base station. Downlink information sent after downlink power control. In addition, it can also be applied to adjacent base stations of the serving cell, thereby reducing cross-slot interference from adjacent base stations.

上述实施例中,引入功率梯度下降机制,基站可以在下行时隙内不同的下行RB区间上使用降低后的不同的第一下行发射功率进行下行传输,从而有效减少来自服务基站的下行自干扰以及来自服务基站的邻基站的交叉时隙干扰,提高了上行传输的可靠性,提高了增强全双工通信的可行性。In the above embodiment, a power gradient descent mechanism is introduced, and the base station can use different reduced first downlink transmit powers for downlink transmission in different downlink RB intervals within the downlink time slot, thereby effectively reducing downlink self-interference from the serving base station. As well as cross-slot interference from neighboring base stations of the serving base station, the reliability of uplink transmission is improved and the feasibility of enhanced full-duplex communication is improved.
第二种方式,在下行时隙内上行频域资源和下行频域资源之间定义guard band。The second method is to define a guard band between the uplink frequency domain resources and the downlink frequency domain resources in the downlink time slot.
本公开实施例提供了一种干扰抑制方法,参照图6A所示,图6A是根据一实施例示出的一种干扰抑制方法流程图,可以由基站执行,该方法可以包括以下步骤:An embodiment of the present disclosure provides an interference suppression method. Refer to Figure 6A. Figure 6A is a flow chart of an interference suppression method according to an embodiment. It can be executed by a base station. The method can include the following steps:
在步骤601中,在进行上行传输的下行时隙内的保护频带上,不进行 数据的发送接收。In step 601, no data is transmitted or received in the guard band within the downlink time slot for uplink transmission.
其中,保护频带位于所述下行时隙内的上行频域资源和下行频域资源之间,参照图6B所示。基站在该guard band(保护频带)上,不进行数据的发送接收。The guard frequency band is located between the uplink frequency domain resources and the downlink frequency domain resources in the downlink time slot, as shown in Figure 6B. The base station is on this guard band and does not send or receive data.
在一个可能的实现方式中,基站可以基于协议约定方式,确定所述下行时隙内所述保护频带所占用的频域资源。In a possible implementation, the base station may determine the frequency domain resources occupied by the guard frequency band in the downlink time slot based on a protocol agreement.
在另一个可能的实现方式中,基站可以基于自身能力配置该保护频带所占用的频域资源,并通过无线资源控制RRC信令向终端指示该保护频带占用的频域资源,以便终端基于该RRC信令的指示,确定对应的频域资源。In another possible implementation, the base station can configure the frequency domain resources occupied by the guard band based on its own capabilities, and indicate the frequency domain resources occupied by the guard band to the terminal through radio resource control RRC signaling, so that the terminal can use the RRC Signaling instructions determine the corresponding frequency domain resources.
上述实施例中,可以设置保护频带,从而有效降低全双工终端在下行时隙内进行上行传输时,来自服务基站的下行自干扰以及来自服务基站的邻基站的交叉时隙干扰,提高了上行传输的可靠性,提高了增强全双工通信的可行性。In the above embodiment, a guard band can be set, thereby effectively reducing downlink self-interference from the serving base station and cross-slot interference from neighboring base stations of the serving base station when the full-duplex terminal performs uplink transmission in the downlink time slot, thereby improving uplink transmission. The reliability of transmission improves the feasibility of enhanced full-duplex communication.
需要说明的是,上述两种方式可以单独实施,也可以组合实施,本公开对此不作限定。It should be noted that the above two methods can be implemented individually or in combination, and this disclosure is not limiting.

在一些可选实施例中,参照图8所示,图8是根据一实施例示出的一种干扰抑制方法流程图,可以由终端执行,该方法可以包括以下步骤:In some optional embodiments, refer to Figure 8, which is a flow chart of an interference suppression method according to an embodiment, which can be executed by a terminal. The method can include the following steps:
在步骤801中,基于协议约定方式,接收所述基站在所述下行时隙所包括的每个下行资源块RB上,使用第一下行发射功率发送的下行信息。In step 801, based on the protocol agreement, receive downlink information sent by the base station using the first downlink transmit power on each downlink resource block RB included in the downlink time slot.
在本公开实施例中,基站可以按照协议约定,确定第一功率回退值,进而基于协议约定方式,在进行上行传输的下行时隙所包括的每个下行RB上,使用回退后的第一下行发射功率进行下行传输,第一下行发射功率可以为基站使用的第二下行发射功率与第一功率回退值的差值,终端可以接收到该基站使用第一下行发射功率发送的下行信息。In this embodiment of the present disclosure, the base station can determine the first power backoff value according to the protocol agreement, and then use the backoff third power backoff value on each downlink RB included in the downlink time slot for uplink transmission based on the protocol agreement method. The first downlink transmission power is used for downlink transmission. The first downlink transmission power can be the difference between the second downlink transmission power used by the base station and the first power backoff value. The terminal can receive the signal sent by the base station using the first downlink transmission power. downward information.
上述实施例中,基站可以在下行时隙内所有下行RB上使用降低后的第一下行发射功率进行下行传输,从而有效减少来自服务基站的下行自干扰以及来自服务基站的邻基站的交叉时隙干扰,提高了上行传输的可靠性,提高了增强全双工通信的可行性。In the above embodiment, the base station can use the reduced first downlink transmit power on all downlink RBs in the downlink time slot for downlink transmission, thereby effectively reducing downlink self-interference from the serving base station and crossover time from neighboring base stations of the serving base station. Slot interference improves the reliability of uplink transmission and the feasibility of enhancing full-duplex communication.
在一些可选实施例中,参照图9所示,图9是根据一实施例示出的一种干扰抑制方法流程图,可以由终端执行,该方法可以包括以下步骤:In some optional embodiments, refer to Figure 9, which is a flow chart of an interference suppression method according to an embodiment, which can be executed by a terminal. The method can include the following steps:
在步骤901中,基于协议约定方式,接收所述基站在所述下行时隙所包括的每个下行RB区间上,使用与所述下行RB区间对应的所述第一下行发射功率发送的下行信息。In step 901, based on the protocol agreement, receive the downlink transmitted by the base station using the first downlink transmit power corresponding to the downlink RB interval in each downlink RB interval included in the downlink time slot. information.
在本公开实施例中,引入功率梯度下降机制,即每个下行RB区间对应不同的第一下行发射功率,则基站可以基于协议约定方式,在进行上行传输的下行时隙所包括的每个下行RB区间上,使用与该下行RB区间对应的第一下行发射功率发送下行信息,终端对应接收即可。In the embodiment of the present disclosure, a power gradient descent mechanism is introduced, that is, each downlink RB interval corresponds to a different first downlink transmit power. Then the base station can, based on the protocol agreement, in each downlink time slot included in the uplink transmission. In the downlink RB interval, the first downlink transmit power corresponding to the downlink RB interval is used to send downlink information, and the terminal can receive it accordingly.
在一个可能的实现方式中,第一下行RB区间对应的第二功率回退值 大于第二下行RB区间对应的第二功率回退值;其中,所述第一下行RB区间相对于上行频域资源的距离小于所述第二下行RB区间相对于所述上行频域资源的距离。In a possible implementation, the second power backoff value corresponding to the first downlink RB interval is greater than the second power backoff value corresponding to the second downlink RB interval; wherein the first downlink RB interval is smaller than the uplink RB interval. The distance of frequency domain resources is smaller than the distance of the second downlink RB interval relative to the uplink frequency domain resources.
第一下行RB区间对应的第一下行发射功率可以为该基站所使用的第二下行发射功率与第一下行RB区间对应的第二功率回退值的差值。同样地,第二下行RB区间对应的第一下行发射功率可以为该基站所使用的第二下行发射功率与第二下行RB区间对应的第二功率回退值的差值。The first downlink transmit power corresponding to the first downlink RB interval may be the difference between the second downlink transmit power used by the base station and the second power backoff value corresponding to the first downlink RB interval. Similarly, the first downlink transmit power corresponding to the second downlink RB interval may be the difference between the second downlink transmit power used by the base station and the second power backoff value corresponding to the second downlink RB interval.
基站(服务小区的基站)可以定义不同下行RB区间对应的功率回退值,远离用于进行上行传输的上行子带的下行频域资源可使用较高的第一下行发射功率进行下行传输,越接近该上行子带的下行频域资源使用较低的第一下行发射功率进行下行传输。The base station (the base station serving the cell) can define power backoff values corresponding to different downlink RB intervals. Downlink frequency domain resources far away from the uplink subband used for uplink transmission can use higher first downlink transmit power for downlink transmission. Downlink frequency domain resources closer to the uplink subband use lower first downlink transmit power for downlink transmission.
还需要说明的是,这里基站侧基于功率梯度下降机制调整不同下行RB对应的第一下行发射功率的方案,可以适用于终端服务小区的基站,这样终端进行下行接收时,接收到的是基站进行下行功率控制后发送的下行信息。另外还可以适用于服务小区的邻基站,从而减少来自邻基站的交叉时隙干扰。It should also be noted that the base station side here adjusts the first downlink transmit power corresponding to different downlink RBs based on the power gradient descent mechanism, which can be applied to the base station of the terminal serving cell. In this way, when the terminal performs downlink reception, what it receives is the base station. Downlink information sent after downlink power control. In addition, it can also be applied to adjacent base stations of the serving cell, thereby reducing cross-slot interference from adjacent base stations.
在另一个可能的实现方式中,不同的所述第一下行发射功率对应不同的最大调制阶数,且所述第一下行发射功率与所述最大调制阶数正相关。即第一下行发射功率越大,最大调制阶数也越大,第一下行发射功率越小,相应的最大调制阶数也越小。In another possible implementation, different first downlink transmit powers correspond to different maximum modulation orders, and the first downlink transmit power is positively correlated with the maximum modulation order. That is, the greater the first downlink transmit power, the greater the maximum modulation order, and the smaller the first downlink transmit power, the corresponding smaller the maximum modulation order.
上述实施例中,基站可以在下行时隙内不同的下行RB区间上使用降低后的不同的第一下行发射功率进行下行传输,从而有效减少来自服务基站的下行自干扰以及来自服务基站的邻基站的交叉时隙干扰,提高了上行传输的可靠性,提高了增强全双工通信的可行性。In the above embodiment, the base station can use different reduced first downlink transmit powers for downlink transmission in different downlink RB intervals within the downlink time slot, thereby effectively reducing downlink self-interference from the serving base station and neighbor interference from the serving base station. The cross-time slot interference of the base station improves the reliability of uplink transmission and improves the feasibility of enhancing full-duplex communication.
第二种方式,在下行时隙内上行频域资源和下行频域资源之间定义guard band(保护频带)。The second method is to define a guard band between the uplink frequency domain resources and the downlink frequency domain resources in the downlink time slot.
参照图10所示,图10是根据一实施例示出的一种干扰抑制方法流程 图,可以由终端执行,该方法可以包括以下步骤:Referring to Figure 10, Figure 10 is a flow chart of an interference suppression method according to an embodiment, which can be executed by a terminal. The method can include the following steps:
在步骤1001中,在进行上行传输的下行时隙内的保护频带上,不期待发送或者接收数据。In step 1001, no data is expected to be transmitted or received on the guard frequency band within the downlink time slot for uplink transmission.
在本公开实施例中,所述保护频带位于所述下行时隙内的上行频域资源和下行频域资源之间,参照图6B所示。终端在该保护频带上不期待发送或者接收数据。In this embodiment of the present disclosure, the guard frequency band is located between the uplink frequency domain resources and the downlink frequency domain resources in the downlink time slot, as shown in FIG. 6B. The terminal does not expect to send or receive data in this guard band.
在一个可能的实现方式中,终端可以基于协议约定方式,确定所述下行时隙内所述保护频带所占用的频域资源。In a possible implementation, the terminal may determine the frequency domain resources occupied by the guard frequency band in the downlink time slot based on the protocol agreement.
在另一个可能的实现方式中,终端可以基于基站发送的RRC信令的指示,确定所述下行时隙内所述保护频带所占用的频域资源。相应地,保护频带的定义与基站能力相关。In another possible implementation, the terminal may determine the frequency domain resources occupied by the guard frequency band in the downlink time slot based on the indication of RRC signaling sent by the base station. Accordingly, the definition of the guard band is related to the base station capabilities.
上述实施例中,可以设置保护频带,从而有效降低全双工终端在下行时隙内进行上行传输时,来自服务基站的下行自干扰以及来自服务基站的邻基站的交叉时隙干扰,提高了上行传输的可靠性,提高了全双工通信的可行性。In the above embodiment, a guard band can be set, thereby effectively reducing downlink self-interference from the serving base station and cross-slot interference from neighboring base stations of the serving base station when the full-duplex terminal performs uplink transmission in the downlink time slot, thereby improving uplink transmission. The reliability of transmission improves the feasibility of full-duplex communication.
需要说明的是,上述两种方式可以独立实施,也可以组合实施,本公开对此不作限定。It should be noted that the above two methods can be implemented independently or in combination, and the present disclosure does not limit this.
下面对本公开提供的干扰抑制方法进一步举例说明如下。The interference suppression method provided by the present disclosure is further illustrated below with examples.
实施例1,假设终端为Rel-18及后续版本终端,具有半双工能力或者具有增强全双工能力,本专利不做任何限定。假设基站侧在TDD(Time Division Duplex,时分双工)频段的下行时隙内执行增强全双工操作,也即同时进行调度下行数据和上行数据。基站侧在执行增强全双工操作时,采用如下方式之一,本申请亦不做任何限定: Embodiment 1 assumes that the terminal is a Rel-18 or later version terminal with half-duplex capability or enhanced full-duplex capability. This patent does not make any limitations. It is assumed that the base station side performs enhanced full-duplex operation in the downlink time slot of the TDD (Time Division Duplex) frequency band, that is, it schedules downlink data and uplink data at the same time. When the base station side performs enhanced full-duplex operation, it adopts one of the following methods, and this application does not impose any restrictions:
DL slot内用于DL传输和UL传输的频域资源相互独立且互不重叠,例如图11A所示;The frequency domain resources used for DL transmission and UL transmission in the DL slot are independent of each other and do not overlap, as shown in Figure 11A;
DL slot内用于DL传输和UL传输的频域资源完全重合,例如图11B所示;The frequency domain resources used for DL transmission and UL transmission in the DL slot completely overlap, as shown in Figure 11B;
DL slot内用于DL传输和UL传输的频域资源部分重合,例如图11C所示。The frequency domain resources used for DL transmission and UL transmission in the DL slot partially overlap, as shown in Figure 11C, for example.
在本实施例中,假设DL slot内用于传输上行的资源和用于传输下行的资源在频域上没有重叠,例如图11A所示。对于在UL subband上进行上行传输的终端而言,其会遭受如下两种强烈的下行干扰:来自本小区的下行传输的自干扰;来自邻小区的下行传输的交叉时隙干扰。In this embodiment, it is assumed that the resources used for uplink transmission and the resources used for downlink transmission in the DL slot do not overlap in the frequency domain, for example, as shown in Figure 11A. For terminals that perform uplink transmission on the UL subband, they will suffer from the following two kinds of strong downlink interference: self-interference from the downlink transmission of the own cell; cross-slot interference from the downlink transmission of neighboring cells.
干扰情况可简化为SINR=S/(N+I Self+I CLI)。其中S为有用信号功率,N为系统噪声,I Self为本小区的自干扰,I CLI为来自邻小区的交叉时隙干扰。为了提升有用信号的SINR,在本实施例中降低或者限制基站侧的下行发射功率,具体地:基站降低与DL slot内上行频域资源相邻的DL RB上的发射功率。在本实施例中,假设通过协议预定义的方式确定基站降低所述能够传输上行的DL slot内所有下行RB上的发射总功率。 The interference situation can be simplified as SINR=S/(N+I Self +I CLI ). Among them, S is the useful signal power, N is the system noise, I Self is the self-interference of this cell, and I CLI is the cross-slot interference from neighboring cells. In order to improve the SINR of the useful signal, in this embodiment, the downlink transmit power on the base station side is reduced or limited. Specifically, the base station reduces the transmit power on the DL RB adjacent to the uplink frequency domain resource in the DL slot. In this embodiment, it is assumed that the base station determines in a protocol-predefined manner to reduce the total transmit power on all downlink RBs in the DL slot capable of uplink transmission.
在本实施例中,假设基站的最大下行发射功率为49dBm,即第二下行发射功率为49dBm。当基站在存在UL subband的DL slot内发送下行数据时,其需要限制其下行发射总功率。具体地,协议规定基站侧需要进行第一功率回退值X dB的最大功率回退。在本实施例中,假设X=10。则基站在存在UL subband的DL slot内发送下行数据时,其最大发射功率为39dBm。In this embodiment, it is assumed that the maximum downlink transmission power of the base station is 49dBm, that is, the second downlink transmission power is 49dBm. When the base station sends downlink data in the DL slot where UL subband exists, it needs to limit its total downlink transmission power. Specifically, the protocol stipulates that the base station side needs to perform a maximum power backoff of the first power backoff value X dB. In this embodiment, assume X=10. When the base station sends downlink data in the DL slot where UL subband exists, its maximum transmit power is 39dBm.
实施例2,假设终端为Rel-18及后续版本终端,具有半双工能力或者具有增强全双工能力,本专利不做任何限定。假设基站侧在TDD(Time Division Duplex,时分双工)频段的下行时隙内执行增强全双工操作,也即同时进行调度下行数据和上行数据。基站侧在执行增强全双工操作时,采用如下方式之一,本申请亦不做任何限定: Embodiment 2 assumes that the terminal is a Rel-18 or later version terminal with half-duplex capability or enhanced full-duplex capability. This patent does not make any limitations. It is assumed that the base station side performs enhanced full-duplex operation in the downlink time slot of the TDD (Time Division Duplex) frequency band, that is, it schedules downlink data and uplink data at the same time. When the base station side performs enhanced full-duplex operation, it adopts one of the following methods, and this application does not impose any restrictions:
DL slot内用于DL传输和UL传输的频域资源相互独立且互不重叠,例如图11A所示;The frequency domain resources used for DL transmission and UL transmission in the DL slot are independent of each other and do not overlap, as shown in Figure 11A;
DL slot内用于DL传输和UL传输的频域资源完全重合,例如图11B所示;The frequency domain resources used for DL transmission and UL transmission in the DL slot completely overlap, as shown in Figure 11B;
DL slot内用于DL传输和UL传输的频域资源部分重合,例如图11C所示。The frequency domain resources used for DL transmission and UL transmission in the DL slot partially overlap, as shown in Figure 11C, for example.
在本实施例中,假设DL slot内用于传输上行的资源和用于传输下行的资源在频域上没有重叠,例如图11A所示。对于在UL subband上进行上行传输的终端而言,其会遭受如下两种强烈的下行干扰:来自本小区的下行传输的自干扰;来自邻小区的下行传输的交叉时隙干扰。In this embodiment, it is assumed that the resources used for uplink transmission and the resources used for downlink transmission in the DL slot do not overlap in the frequency domain, for example, as shown in Figure 11A. For terminals that perform uplink transmission on the UL subband, they will suffer from the following two kinds of strong downlink interference: self-interference from the downlink transmission of the own cell; cross-slot interference from the downlink transmission of neighboring cells.
干扰情况可简化为SINR=S/(N+I Self+I CLI)。其中S为有用信号功率,N为系统噪声,I Self为本小区的自干扰,I CLI为来自邻小区的交叉时隙干扰。为了提升有用信号的SINR,在本实施例中降低或者限制基站侧的下行发射功率,具体地:基站降低与DL slot内上行频域资源相邻的DL RB上的发射功率。在本实施例中,假设通过协议预定义的方式引入功率梯度下降机制,定义不同RB区间对应的power reduction(功率下降)数值,即第二功率回退值。总体上而言,远离UL subband的DL频域资源可采用较高的发送功率进行下行发送,接近UL subband的DL频域资源采用较低的发送功率进行下行发送。 The interference situation can be simplified as SINR=S/(N+I Self +I CLI ). Among them, S is the useful signal power, N is the system noise, I Self is the self-interference of this cell, and I CLI is the cross-slot interference from neighboring cells. In order to improve the SINR of the useful signal, in this embodiment, the downlink transmit power on the base station side is reduced or limited. Specifically, the base station reduces the transmit power on the DL RB adjacent to the uplink frequency domain resource in the DL slot. In this embodiment, it is assumed that a power gradient reduction mechanism is introduced in a predefined manner in the protocol, and power reduction (power reduction) values corresponding to different RB intervals are defined, that is, the second power backoff value. Generally speaking, DL frequency domain resources far away from the UL subband can use higher transmission power for downlink transmission, and DL frequency domain resources close to the UL subband can use lower transmission power for downlink transmission.
在本实施例中,假设在存在UL subband的DL slot内定义了3个gNB power level。具体地,可通过如下方式定义三种power level,参照图12所示:In this embodiment, it is assumed that 3 gNB power levels are defined in the DL slot where UL subband exists. Specifically, three power levels can be defined in the following ways, as shown in Figure 12:
Power level 1:power reduction 6dB;Power level 1: power reduction 6dB;
Power level 2:power reduction 3dB;Power level 2: power reduction 3dB;
Power level 3:power reduction 0dB;Power level 3: power reduction 0dB;
本专利对于power level数量和每个power level对应地power reduction数值不做任何要求。This patent does not place any requirements on the number of power levels and the power reduction value corresponding to each power level.
实施例3,如实施例2所述,所述不同功率等级对应的modulation order set(调整阶数集)不同。例如对于上述power level#3,最高支持256QAM(Quadrature Amplitude Modulation,正交振幅调制),对于Power level#2,最高支持64QAM;对于Power level#1,最高支持16QAM。Embodiment 3: As described in Embodiment 2, the different power levels correspond to different modulation order sets. For example, for the above power level #3, it supports up to 256QAM (Quadrature Amplitude Modulation, Quadrature Amplitude Modulation), for Power level #2, it supports up to 64QAM; for Power level #1, it supports up to 16QAM.
当基站调度的PDSCH传输的频域资源跨越多个power level范围,则可在不同的频域位置上采用不同的modulation order对所述TB进行调制。When the frequency domain resources of PDSCH transmission scheduled by the base station span multiple power level ranges, the TB can be modulated using different modulation orders at different frequency domain positions.
实施例4,假设终端为Rel-18及后续版本终端,具有半双工能力或者具有增强全双工能力,本专利不做任何限定。假设基站侧在TDD(Time Division Duplex,时分双工)频段的下行时隙内执行增强全双工操作,也即同时进行调度下行数据和上行数据。基站侧在执行增强全双工操作时,采用如下方式之一,本申请亦不做任何限定:Embodiment 4 assumes that the terminal is a Rel-18 or later version terminal with half-duplex capability or enhanced full-duplex capability. This patent does not make any limitations. It is assumed that the base station side performs enhanced full-duplex operation in the downlink time slot of the TDD (Time Division Duplex) frequency band, that is, it schedules downlink data and uplink data at the same time. When the base station side performs enhanced full-duplex operation, it adopts one of the following methods, and this application does not impose any restrictions:
DL slot内用于DL传输和UL传输的频域资源相互独立且互不重叠,例如图11A所示;The frequency domain resources used for DL transmission and UL transmission in the DL slot are independent of each other and do not overlap, as shown in Figure 11A;
DL slot内用于DL传输和UL传输的频域资源完全重合,例如图11B所示;The frequency domain resources used for DL transmission and UL transmission in the DL slot completely overlap, as shown in Figure 11B;
DL slot内用于DL传输和UL传输的频域资源部分重合,例如图11C所示。The frequency domain resources used for DL transmission and UL transmission in the DL slot partially overlap, as shown in Figure 11C, for example.
在本实施例中,假设DL slot内用于传输上行的资源和用于传输下行的资源在频域上没有重叠,例如图11A所示。对于在UL subband上进行上行传输的终端而言,其会遭受如下两种强烈的下行干扰:来自本小区的下行传输的自干扰;来自邻小区的下行传输的交叉时隙干扰。In this embodiment, it is assumed that the resources used for uplink transmission and the resources used for downlink transmission in the DL slot do not overlap in the frequency domain, for example, as shown in Figure 11A. For terminals that perform uplink transmission on the UL subband, they will suffer from the following two kinds of strong downlink interference: self-interference from the downlink transmission of the own cell; cross-slot interference from the downlink transmission of neighboring cells.
干扰情况可简化为SINR=S/(N+I Self+I CLI)。其中S为有用信号功率,N为系统噪声,I Self为本小区的自干扰,I CLI为来自邻小区的交叉时隙干扰。为了提升有用信号的SINR,降低如上两种下行干扰的影响,本专利在DL slot内定义用于传输上行的频域资源和用于传输下行的频域资源之间定义guard band。所述guard band用于隔离来自下行传输的频率泄露、谐波干扰以及滤波器滚降特性带来的残余干扰。在所述guard band内,基站不发送任何下行信道或者下行信号。在guard band内,终端不发送任何上行信道或者上行信号。 The interference situation can be simplified as SINR=S/(N+I Self +I CLI ). Among them, S is the useful signal power, N is the system noise, I Self is the self-interference of this cell, and I CLI is the cross-slot interference from neighboring cells. In order to improve the SINR of the useful signal and reduce the impact of the above two downlink interferences, this patent defines a guard band between the frequency domain resources used for uplink transmission and the frequency domain resources used for downlink transmission in the DL slot. The guard band is used to isolate frequency leakage from downlink transmission, harmonic interference, and residual interference caused by filter roll-off characteristics. Within the guard band, the base station does not send any downlink channels or downlink signals. Within the guard band, the terminal does not send any uplink channels or uplink signals.
所述guard band可通过如下方式确定,本专利不做任何限制:所述guard band通过协议预定义的方式确定;或者,所述guard band通过基站 发送的RRC signaling进行配置。The guard band can be determined in the following ways, and this patent does not impose any restrictions: the guard band is determined in a predefined manner by the protocol; or, the guard band is configured through RRC signaling sent by the base station.
实施例5,如上实施例1-实施例4,所述方法可应用于服务基站,亦可应用于邻基站,本专利不做任何限定。如上实施例1-实施例4中所发方法可结合使用,本专利亦不做任何限定。Embodiment 5 is as described in Embodiment 1 to Embodiment 4 above. The method can be applied to the serving base station or to the adjacent base station. This patent does not impose any limitations. The methods described in Examples 1 to 4 above can be used in combination, and this patent does not impose any limitations.
上述实施例中,可以有效降低全双工终端在下行时隙内进行上行传输时,来自服务基站的下行自干扰以及来自服务基站的邻基站的交叉时隙干扰,提高了上行传输的可靠性,提高了增强全双工通信的可行性。In the above embodiment, when a full-duplex terminal performs uplink transmission in a downlink time slot, downlink self-interference from the serving base station and cross-time slot interference from neighboring base stations of the serving base station can be effectively reduced, thereby improving the reliability of uplink transmission. Improved feasibility of enhanced full-duplex communications.
