This will result in PRACH not having time to complete when the PRACH transmission opportunity arrives. Prepare, unable to successfully transmit PRACH. Therefore, for eRedCap terminals, it is no longer applicable to constrain the timing relationship between PDCCH and PRACH based on the processing capabilities of traditional terminals.

为了便于理解，首先介绍本实施例涉及的术语。To facilitate understanding, the terminology involved in this embodiment is first introduced.

1、物理上行共享信道(Physical Uplink Shared Channel，PUSCH)1. Physical Uplink Shared Channel (PUSCH)

PUSCH作为物理层主要的上行数据承载信道，用于上行数据的传输，可以承载控制信息、用户业务信息和广播业务信息等。As the main uplink data bearing channel of the physical layer, PUSCH is used for the transmission of uplink data and can carry control information, user service information, broadcast service information, etc.

2、物理下行共享信道(Physical Downlink Shared Channel，PDSCH)2. Physical Downlink Shared Channel (PDSCH)

PDSCH用于承载来自传输下行共享信道(Downlink Shared Channel，DL-SCH)的数据。PDSCH is used to carry data from the transmission downlink shared channel (Downlink Shared Channel, DL-SCH).

3、物理随机接入信道(Physical Random Access Channel，PRACH)3. Physical Random Access Channel (PRACH)

PRACH信道是用户设备(User Equipment，UE)一开始发起随机时的接入信道。The PRACH channel is the access channel when the user equipment (User Equipment, UE) initially initiates randomization.

4、eRedCap终端4. eRedCap terminal

第三代合作伙伴项目(3rd Generation Partnership Project，3GPP)在通信协议版本17(release17，Rel-17)阶段成立了专门的标准项目来分析并优化现有的5G终端和网络的功能特性来实现5G物联网终端通过5G新空口(New Radio，NR)接入5G核心网。在这个标准项目中，3GPP提出了支持能力降低(Reduced Capability)的NR设备，亦即RedCap终端。与传统的增强移动宽带(enhanced mobile broadband，eMBB)设备、超可靠低时延通信(ultra-reliable and low latencycommunication，URLLC)设备相比，RedCap终端设备具有成本更低、复杂度低、尺寸更紧凑、性能够用等优势。而eRedCap终端是在RedCap终端的基础上，进一步降低终端成本，来支持速率较低的5G物联网终端使用NR技术。The 3rd Generation Partnership Project (3GPP) established a special standards project in the communication protocol version 17 (release17, Rel-17) stage to analyze and optimize the functional characteristics of existing 5G terminals and networks to implement 5G IoT terminals access the 5G core network through 5G New Radio (NR). In this standard project, 3GPP proposed NR equipment that supports reduced capability (Reduced Capability), also known as RedCap terminal. Compared with traditional enhanced mobile broadband (eMBB) equipment and ultra-reliable and low latency communication (URLLC) equipment, RedCap terminal equipment has lower cost, lower complexity, and more compact size , performance and other advantages. The eRedCap terminal is based on the RedCap terminal, further reducing terminal costs to support lower-speed 5G IoT terminals using NR technology.

目前通信协议版本18(R18)研究项目中提出要放松终端的处理时延，如针对PDSCH信道的处理时间(processingtime)和PUSCH信道的准备时间(preparation time)进行处理时延放松，以降低终端成本。如果eRedCap终端采用与传统终端相同的处理能力来确定PDCCH与PRACH之间的最小时间间隔(time gap)。并且对于基站而言，如果根据传统的能力对终端进行调度，则可能导致PDCCH与PRACH之间的最小时间间隔小于PRACH的准备时延，这样会导致在PRACH发送时机到来时PRACH还未来得及做好准备，无法成功传输PRACH。因此，对于eRedCap终端而言，根据传统终端的处理能力来约束PDCCH与PRACH之间的时序关系将不再适用。The current communication protocol version 18 (R18) research project proposes to relax the processing delay of the terminal, such as relaxing the processing time of the PDSCH channel (processing time) and the preparation time (preparation time) of the PUSCH channel to reduce terminal costs. . If the eRedCap terminal uses the same processing capabilities as the traditional terminal to determine the minimum time gap (time gap) between PDCCH and PRACH. And for the base station, if the terminal is scheduled based on traditional capabilities, the minimum time interval between PDCCH and PRACH may be smaller than the PRACH preparation delay. This will result in PRACH not having time to complete when the PRACH transmission opportunity arrives. Prepare, unable to successfully transmit PRACH. Therefore, for eRedCap terminals, it is no longer applicable to constrain the timing relationship between PDCCH and PRACH based on the processing capabilities of traditional terminals.

为此，本实施例提出了一种PDCCH与PRACH之间时序关系的确定方法及装置，提供了一种为eRedCap终端确定PDCCH信道与PRACH信道之间时序关系的有效解决方案，以确保在PRACH传输时机到来之前能够准备好PRACH序列，同时确保基站能够进行合理的调度。To this end, this embodiment proposes a method and device for determining the timing relationship between the PDCCH and PRACH, and provides an effective solution for determining the timing relationship between the PDCCH channel and the PRACH channel for eRedCap terminals to ensure that the PRACH transmission The PRACH sequence can be prepared before the time comes, while ensuring that the base station can perform reasonable scheduling.

下面结合附图对本申请所提供的PDCCH与PRACH之间时序关系的确定方法及装置进行详细地介绍。The method and device for determining the timing relationship between PDCCH and PRACH provided by this application will be introduced in detail below with reference to the accompanying drawings.

图1示出了根据本申请实施例的其中一种PDCCH与PRACH之间时序关系的确定方法的流程示意图。如图1所示，可应用于eRedCap终端侧或者基站侧执行，可以包括以下步骤。Figure 1 shows a schematic flowchart of a method for determining the timing relationship between PDCCH and PRACH according to an embodiment of the present application. As shown in Figure 1, it can be applied to eRedCap terminal side or base station side execution, and may include the following steps.

步骤101、获取eRedCap终端的PUSCH信道的处理能力。Step 101: Obtain the processing capability of the PUSCH channel of the eRedCap terminal.

获取到的eRedCap终端的PUSCH信道的处理能力，即可认为是相比于RedCap终端和传统终端，为eRedCap终端新引入的PUSCH信道的处理能力。The obtained processing capability of the PUSCH channel of the eRedCap terminal can be considered as the processing capability of the PUSCH channel newly introduced to the eRedCap terminal compared to the RedCap terminal and the traditional terminal.

eRedCap终端的PUSCH信道的处理能力可低于RedCap终端的PUSCH信道的处理能力，eRedCap终端关于PUSCH信道的处理时延会得到放松，而RedCap终端的PUSCH信道的处理能力可与传统终端的PUSCH信道的处理能力相同。The processing capability of the PUSCH channel of the eRedCap terminal can be lower than that of the RedCap terminal. The processing delay of the PUSCH channel of the eRedCap terminal will be relaxed, and the processing capability of the PUSCH channel of the RedCap terminal can be the same as that of the PUSCH channel of the traditional terminal. The processing power is the same.

步骤102、基于eRedCap终端的PUSCH信道的处理能力，确定eRedCap终端的PDCCH与PRACH之间的时序关系。Step 102: Based on the processing capability of the PUSCH channel of the eRedCap terminal, determine the timing relationship between the PDCCH and PRACH of the eRedCap terminal.

例如，基于eRedCap终端的PUSCH信道的处理能力，确定eRedCap终端的PDCCH信道与PRACH信道之间的最小时间间隔，以便根据该PDCCH信道与PRACH信道之间的最小时间间隔，在PRACH传输时机到来之前能够准备好PRACH序列。For example, based on the processing capability of the PUSCH channel of the eRedCap terminal, determine the minimum time interval between the PDCCH channel and the PRACH channel of the eRedCap terminal, so that according to the minimum time interval between the PDCCH channel and the PRACH channel, it can be transmitted before the PRACH transmission opportunity arrives. Prepare the PRACH sequence.

通过应用本实施例提供的PDCCH与PRACH之间时序关系的确定方法，可基于对eRedCap终端的PUSCH信道的处理能力，确定eRedCap终端的PDCCH与PRACH之间的时序关系，其中，eRedCap终端的PUSCH信道的处理能力低于RedCap终端的PUSCH信道的处理能力，以确保在PRACH传输时机到来之前能够准备好PRACH序列，同时确保基站能够进行合理的调度。By applying the method for determining the timing relationship between PDCCH and PRACH provided in this embodiment, the timing relationship between the PDCCH and PRACH of the eRedCap terminal can be determined based on the processing capability of the PUSCH channel of the eRedCap terminal, where the PUSCH channel of the eRedCap terminal The processing capacity is lower than the processing capacity of the PUSCH channel of the RedCap terminal to ensure that the PRACH sequence can be prepared before the PRACH transmission opportunity arrives, and at the same time ensure that the base station can perform reasonable scheduling.

图2示出了根据本申请实施例的其中一种PDCCH与PRACH之间时序关系的确定方法的流程示意图。基于图1所示实施例，如图2所示，可应用于eRedCap终端侧，且该方法可以包括以下步骤。Figure 2 shows a schematic flowchart of a method for determining the timing relationship between PDCCH and PRACH according to an embodiment of the present application. Based on the embodiment shown in Figure 1, as shown in Figure 2, it can be applied to the eRedCap terminal side, and the method can include the following steps.

步骤201、获取eRedCap终端的PUSCH信道的处理能力，该处理能力低于RedCap终端的PUSCH信道的处理能力。Step 201: Obtain the processing capability of the PUSCH channel of the eRedCap terminal, which is lower than the processing capability of the PUSCH channel of the RedCap terminal.

步骤202、若eRedCap终端支持eRedCap终端的PUSCH信道的处理能力，则基于eRedCap终端的PUSCH信道的处理能力，确定eRedCap终端的PDCCH与PRACH之间的时序关系。Step 202: If the eRedCap terminal supports the processing capability of the PUSCH channel of the eRedCap terminal, determine the timing relationship between the PDCCH and PRACH of the eRedCap terminal based on the processing capability of the PUSCH channel of the eRedCap terminal.

在具体的应用中，一种可选的方式是使得eRedCap终端仅支持新引入的PUSCH信道的处理能力(相比于RedCap终端和传统终端，为eRedCap终端新引入的PUSCH信道的处理能力，因此可以称为新引入的PUSCH信道的处理能力)。例如，eRedCap终端仅支持新引入的PUSCH信道的处理能力(UE processing capability 1’)，在这种情况下，可基于该新引入的PUSCH信道的处理能力(UE processing capability 1’)，来确定eRedCap终端的PDCCH与PRACH之间的时序关系。In a specific application, an optional method is to make the eRedCap terminal only support the processing capabilities of the newly introduced PUSCH channel (compared to RedCap terminals and traditional terminals, the processing capabilities of the newly introduced PUSCH channel for eRedCap terminals, so it can is called the processing capability of the newly introduced PUSCH channel). For example, the eRedCap terminal only supports the processing capability of the newly introduced PUSCH channel (UE processing capability 1'). In this case, the eRedCap can be determined based on the processing capability of the newly introduced PUSCH channel (UE processing capability 1'). The timing relationship between the terminal's PDCCH and PRACH.

另一种可选方式是使得新引入的PUSCH信道的处理能力是eRedCap终端必须支持的能力。例如，eRedCap终端在实际中有可能还会支持PUSCH信道的处理能力1(UE processing capability 1)，该处理能力1与RedCap终端或者传统终端的信道处理能力1相同，对于RedCap终端或者传统终端来说，信道处理能力1可以是一种强制性的能力，必须支持。进一步的，eRedCap终端在实际中有可能还会支持PUSCH信道的处理能力2(UEprocessingcapability 2)，该处理能力2与RedCap终端或者传统终端的信道处理能力2相同，对于RedCap终端或者传统终端来说，信道处理能力2可作为一种可选的能力。对于eRedCap终端，如果新引入的PUSCH信道的处理能力(UE processing capability 1’)是eRedCap终端必须支持的能力，则无论eRedCap终端是否支持处理能力1(UE processing capability 1)、处理能力2(UEprocessingcapability 2)，均基于新引入的PUSCH信道的处理能力(UE processing capability 1’)来确定eRedCap终端的PDCCH与PRACH之间的时序关系。Another optional method is to make the processing capability of the newly introduced PUSCH channel a capability that eRedCap terminals must support. For example, eRedCap terminals may actually support PUSCH channel processing capability 1 (UE processing capability 1). This processing capability 1 is the same as the channel processing capability 1 of RedCap terminals or traditional terminals. For RedCap terminals or traditional terminals , Channel processing capability 1 can be a mandatory capability that must be supported. Furthermore, eRedCap terminals may actually support PUSCH channel processing capability 2 (UE processing capability 2). This processing capability 2 is the same as the channel processing capability 2 of RedCap terminals or traditional terminals. For RedCap terminals or traditional terminals, Channel processing capability 2 is available as an optional capability. For eRedCap terminals, if the newly introduced PUSCH channel processing capability (UE processing capability 1') is a capability that the eRedCap terminal must support, then regardless of whether the eRedCap terminal supports processing capability 1 (UE processing capability 1), processing capability 2 (UEprocessingcapability 2 ), both determine the timing relationship between the PDCCH and PRACH of the eRedCap terminal based on the newly introduced processing capability of the PUSCH channel (UE processing capability 1').

又一种可选方式是根据eRedCap终端支持的处理能力情况而定。例如，在实际应用中，新引入的PUSCH信道的处理能力(UE processing capability 1’)并不是全部eRedCap终端均能够支持的能力。对于新引入的处理能力(UE processing capability 1’)，eRedCap终端可能支持也可能不支持，因此可根据eRedCap终端支持的处理能力情况，如果eRedCap终端支持新引入的PUSCH信道的处理能力(UE processing capability 1’)，则基于新引入的PUSCH信道的处理能力(UE processing capability 1’)来确定eRedCap终端的PDCCH与PRACH之间的时序关系；如果eRedCap终端不支持新引入的PUSCH信道的处理能力(UE processing capability 1’)，则可基于eRedCap终端支持的处理能力来确定eRedCap终端的PDCCH与PRACH之间的时序关系。Another optional method is based on the processing capabilities supported by the eRedCap terminal. For example, in practical applications, the newly introduced PUSCH channel processing capability (UE processing capability 1’) is not a capability that all eRedCap terminals can support. For the newly introduced processing capability (UE processing capability 1'), the eRedCap terminal may or may not support it. Therefore, according to the processing capabilities supported by the eRedCap terminal, if the eRedCap terminal supports the newly introduced processing capability of the PUSCH channel (UE processing capability 1'), the timing relationship between the PDCCH and PRACH of the eRedCap terminal is determined based on the processing capability of the newly introduced PUSCH channel (UE processing capability 1'); if the eRedCap terminal does not support the processing capability of the newly introduced PUSCH channel (UE processing capability 1'), the timing relationship between the PDCCH and PRACH of the eRedCap terminal can be determined based on the processing capabilities supported by the eRedCap terminal.

为了说明具体如何基于eRedCap终端的PUSCH信道的处理能力，确定eRedCap终端的PDCCH与PRACH之间的时序关系，可选的，该过程具体可包括：依据eRedCap终端支持的处理能力对应的PUSCH信道的准备时间(preparation time)，确定eRedCap终端的PDCCH与PRACH之间的最小时间间隔。In order to explain how to determine the timing relationship between the PDCCH and PRACH of the eRedCap terminal based on the processing capabilities of the PUSCH channel of the eRedCap terminal, optionally, the process may specifically include: preparation of the PUSCH channel corresponding to the processing capabilities supported by the eRedCap terminal. Time (preparation time) determines the minimum time interval between the PDCCH and PRACH of the eRedCap terminal.

例如，可通过如下公式一，确定eRedCap终端的PDCCH与PRACH之间的最小时间间隔：For example, the minimum time interval between the PDCCH and PRACH of the eRedCap terminal can be determined through the following formula 1:

N _T,2+Δ _BWPSwitching+Δ _Delay+T _switch (公式一) N _T,2 +Δ _BWPSwitching +Δ _Delay +T _switch (Formula 1)

公式一中，N _T,2代表eRedCap终端支持的处理能力(新引入的)对应的PUSCH信道的准备时间(PUSCH preparation time)；Δ _BWPSwitching代表BWP的切换时延；Δ _Delay代表MAC层处理时延；T _switch代表载波切换时延。 In Formula 1, N _T,2 represents the PUSCH preparation time (PUSCH preparation time) corresponding to the processing capability supported by the eRedCap terminal (newly introduced); Δ _BWPSwitching represents the BWP switching delay; Δ _Delay represents the MAC layer processing delay. ;T _switch represents the carrier switching delay.

通过上述示例性的方式，可依据eRedCap终端支持的处理能力对应的PUSCH信道的准备时间，准确确定eRedCap终端的PDCCH与PRACH之间的时序关系。Through the above exemplary method, the timing relationship between the PDCCH and PRACH of the eRedCap terminal can be accurately determined based on the preparation time of the PUSCH channel corresponding to the processing capabilities supported by the eRedCap terminal.

通过应用本实施例提供的PDCCH与PRACH之间时序关系的确定方法，在eRedCap终端仅支持新引入的PUSCH信道的处理能力、或者必须支持新引入的PUSCH信道的处理能力(终端还可支持其他处理能力)、或者eRedCap终端可支持新引入的PUSCH信道的处理能力的情况下，均基于新引入的PUSCH信道的处理能力来确定eRedCap终端的PDCCH与PRACH之间的时序关系。在放松终端的处理时延的需求场景下，可为eRedCap终端重新确定PDCCH与PRACH之间的时序关系，以确保在PRACH传输时机到来之前能够准备好PRACH序列。By applying the method for determining the timing relationship between PDCCH and PRACH provided in this embodiment, the eRedCap terminal only supports the processing capabilities of the newly introduced PUSCH channel, or must support the processing capabilities of the newly introduced PUSCH channel (the terminal can also support other processing capabilities capability), or the eRedCap terminal can support the processing capability of the newly introduced PUSCH channel, the timing relationship between the PDCCH and PRACH of the eRedCap terminal is determined based on the processing capability of the newly introduced PUSCH channel. In scenarios where the processing delay of the terminal needs to be relaxed, the timing relationship between PDCCH and PRACH can be redetermined for the eRedCap terminal to ensure that the PRACH sequence can be prepared before the PRACH transmission opportunity arrives.

图5为根据本申请实施例的其中一种PDCCH与PRACH之间时序关系的确定方法的流程示意图。基于图1所示实施例，如图5所示，可应用于基站侧执行，该方法可以包括以下步骤。Figure 5 is a schematic flowchart of a method for determining the timing relationship between PDCCH and PRACH according to an embodiment of the present application. Based on the embodiment shown in Figure 1, as shown in Figure 5, it can be applied to the base station side and the method can include the following steps.

步骤501、获取eRedCap终端的PUSCH信道的处理能力，该处理能力低于RedCap终端的PUSCH信道的处理能力。Step 501: Obtain the processing capability of the PUSCH channel of the eRedCap terminal, which is lower than the processing capability of the PUSCH channel of the RedCap terminal.

步骤502、基于eRedCap终端上报的处理能力信息，确定eRedCap终端是否支持eRedCap终端的PUSCH信道的处理能力。Step 502: Based on the processing capability information reported by the eRedCap terminal, determine whether the eRedCap terminal supports the processing capability of the PUSCH channel of the eRedCap terminal.

在具体的应用中，如果eRedCap终端的PUSCH信道的处理能力(即UE processing capability 1’)不是eRedCap终端仅支持的能力，或者不是eRedCap终端必须支持的能力(终端还可支持其他处理能力)，在这种情况下，eRedCap终端的PUSCH信道的处理能力(UE processing capability 1’)并不是全部eRedCap终端均能够支持的能力。对于eRedCap终端的处理能力(UE processing capability 1’)，eRedCap终端可能支持也可能不支持，因此在基站侧，需要基于eRedCap终端上报的处理能力信息(如通过UEcapability信令上报不支持该处理能力(UE processing capability 1’)、或未上报支持该处理能力(UE processing capability 1’)并上报了还支持其他处理能力等)，来确定eRedCap终端是否支持处理能力(UE processing capability 1’)。In a specific application, if the processing capability of the PUSCH channel of the eRedCap terminal (i.e. UE processing capability 1') is not a capability that the eRedCap terminal only supports, or is not a capability that the eRedCap terminal must support (the terminal can also support other processing capabilities), in In this case, the processing capability of the PUSCH channel of the eRedCap terminal (UE processing capability 1') is not a capability that all eRedCap terminals can support. For the processing capability of the eRedCap terminal (UE processing capability 1'), the eRedCap terminal may or may not support it. Therefore, on the base station side, it needs to be based on the processing capability information reported by the eRedCap terminal (such as reporting through UEcapability signaling that the processing capability is not supported ( UE processing capability 1'), or has not reported support for this processing capability (UE processing capability 1') and reported support for other processing capabilities, etc.) to determine whether the eRedCap terminal supports processing capability (UE processing capability 1').

In this exemplary manner, the timing relationship between the PDCCH and PRACH of the eRedCap terminal can be accurately determined.

具体的实现过程可参见步骤202中的解释说明，在此不再赘述。For the specific implementation process, please refer to the explanation in step 202, which will not be described again here.

步骤504、基于确定得到的PDCCH与PRACH之间的时序关系，执行eRedCap终端随机接入的调度。Step 504: Based on the determined timing relationship between the PDCCH and the PRACH, perform random access scheduling for the eRedCap terminal.

例如，在基站侧，在得到PDCCH与PRACH之间的时序关系之后，可基于确定得到的PDCCH与PRACH之间的时序关系，进行PDCCHordering的PRACH的调度。For example, on the base station side, after obtaining the timing relationship between the PDCCH and the PRACH, the PRACH scheduling of the PDCCH ordering can be performed based on the determined timing relationship between the PDCCH and the PRACH.

通过应用本实施例提供的PDCCH与PRACH之间时序关系的确定方法，在基站侧，可基于对eRedCap终端的PUSCH信道的处理能力，准确确定eRedCap终端的PDCCH与PRACH之间的时序关系，然后，基于确定得到的PDCCH与PRACH之间的时序关系，执行eRedCap终端随机接入的调度，确保基站能够进行合理的调度。By applying the method for determining the timing relationship between PDCCH and PRACH provided in this embodiment, on the base station side, the timing relationship between the PDCCH and PRACH of the eRedCap terminal can be accurately determined based on the processing capability of the PUSCH channel of the eRedCap terminal. Then, Based on the determined timing relationship between the PDCCH and PRACH, the eRedCap terminal random access scheduling is performed to ensure that the base station can perform reasonable scheduling.
