5G NR系统独立工作在非授权频谱时,不能获得稳定连续的信道资源的原因是:When the 5G NR system works independently on unlicensed spectrum, the reason why stable and continuous channel resources cannot be obtained is:
当前5G NR系统通过广播方式为终端配置1个初始BWP,终端在初始BWP上接收寻呼和系统消息,并在初始BWP上发起随机接入。如果该初始BWP上的WIFI业务较多,就可能会导致5G NR系统获取信道资源的机会较少,对系统性能产生影响。另一方面,当处于连接态时,终端只允许被激活1个BWP,并在激活的BWP上进行数据收发,如果该激活的BWP上WIFI干扰较大,可能5G NR系统获取信道资源的机会较少,也会对系统性能产生影响。The current 5G NR system configures an initial BWP for the terminal through broadcast. The terminal receives paging and system messages on the initial BWP, and initiates random access on the initial BWP. If there are more WIFI services on the initial BWP, it may result in less opportunities for the 5G NR system to obtain channel resources, which will affect the system performance. On the other hand, when in the connected state, the terminal is only allowed to be activated one BWP, and send and receive data on the activated BWP, if the WIFI interference on the activated BWP is greater, the 5G NR system may have a greater chance of acquiring channel resources Less will also have an impact on system performance.
基于此,在本申请的各种实施例中:配置多个初始BWP或者激活多个BWP,以便能够通过进行LBT,LBT成功后进行数据发送,并在相应BWP上进行数据接收。Based on this, in various embodiments of the present application: configuring multiple initial BWPs or activating multiple BWPs, so as to enable LBT, after successful LBT, data transmission is performed, and data reception is performed on the corresponding BWP.
本申请实施例提供的方案,由于配置了多个工作BWP,且在发送数据之前进行了LBT,如此,能够大大增加5G系统获取信道资源的机会,从而保证了系统性能。The solution provided in this embodiment of the present application is configured with multiple working BWPs and LBT is performed before sending data. In this way, the chance of the 5G system acquiring channel resources can be greatly increased, thereby ensuring system performance.

具体地,所述终端有以下几种实现过程:Specifically, the terminal has the following implementation processes:

这里,实际应用时,可以根据需要选择上述一种实现过程。Here, in actual application, one of the above-mentioned implementation processes can be selected as needed.
实际应用时,当所述终端处于空闲态时,数据的发送和接收主要是随 机接入过程中的数据发送和接收,比如MSG1、MSG2、MSG3和MSG4等。In practical applications, when the terminal is in an idle state, data transmission and reception are mainly data transmission and reception during random access, such as MSG1, MSG2, MSG3, and MSG4.

具体地,在时分双工(TDD)系统中,二者的关系可以是上行BWP与下行BWP具有相同的BWP索引,或者可以是上行BWP与下行BWP具有不同的BWP索引。Specifically, in a time division duplex (TDD) system, the relationship between the two may be that the uplink BWP and the downlink BWP have the same BWP index, or that the uplink BWP and the downlink BWP have different BWP indexes.
在频分双工(FDD)系统中,二者的关系可以存在上下行BWP的配对关系,或者可以是不存在上下行BWP的配对关系。In a frequency division duplex (FDD) system, the relationship between the two may be a pairing relationship between upstream and downstream BWPs, or may be a pairing relationship that does not exist between upstream and downstream BWPs.
实际应用时,在TDD系统中,所述终端可以优先在上行BWP对应的下行BWP(与上行BWP具有相同的BWP索引)上接收下行数据。In practical applications, in a TDD system, the terminal may preferentially receive downlink data on a downlink BWP (which has the same BWP index as the uplink BWP) corresponding to the uplink BWP.
在FDD系统中,所述终端可以优先在与上行BWP配对的下行BWP上接收下行数据。In the FDD system, the terminal may preferentially receive downlink data on the downlink BWP paired with the uplink BWP.
在一实施例中,在多个上行BWP上进行LBT,所述在一个上行BWP上进行数据发送,包括以下之一:In an embodiment, LBT is performed on multiple upstream BWPs, and the sending data on one upstream BWP includes one of the following:
在LBT最先成功的BWP上进行数据发送;Send data on the BWP which was the first successful LBT;
在LBT成功率最高的一个BWP上进行数据发送;Send data on a BWP with the highest LBT success rate;
在第一预设时长内LBT成功率最高的一个BWP上进行数据发送;Send data on the BWP with the highest LBT success rate within the first preset duration;

在符合第一门限要求的一个BWP上进行数据发送。Send data on a BWP that meets the first threshold.
这里,实际应用时,所述终端可以根据需要选择一个上行BWP配置为数据发送。Here, in actual application, the terminal may select an uplink BWP to be configured for data transmission as needed.
其中,LBT成功率是指:在一段时间内LBT成功的次数与该段时间内 LBT的次数的比值。Among them, the LBT success rate refers to: the ratio of the number of LBT successes in a period of time to the number of LBTs in that period of time.
在一实施例中,在多个上行BWP上进行LBT,所述在多个上行BWP上进行数据发送,包括以下之一:In an embodiment, LBT is performed on multiple upstream BWPs, and the sending data on multiple upstream BWPs includes one of the following:
在LBT成功的多个BWP上进行数据发送;Send data on multiple BWPs with successful LBT;
在LBT成功率较高的多个BWP上进行数据发送;Send data on multiple BWPs with high LBT success rate;
在LBT成功次数较高的多个BWP上进行数据发送;Send data on multiple BWPs with a high number of LBT successes;
在第三预设时长内LBT成功率较高的多个BWP上进行数据发送;Send data on multiple BWPs with a high LBT success rate within the third preset duration;

在符合第二门限要求的BWP上进行数据发送。Send data on BWP that meets the second threshold.
其中,实际应用时,相应门限要求(比如第一门限、第二门限)包括以下至少一种:In practice, the corresponding threshold requirements (such as the first threshold and the second threshold) include at least one of the following:

RSRP。RSRP.
这里,与LBT成功率对应的,LBT失败率是指:一段时间内LBT失败的次数与该时间段内LBT次数的比值。Here, corresponding to the LBT success rate, the LBT failure rate refers to: the ratio of the number of LBT failures in a period of time to the number of LBTs in the period of time.
实际应用时,所述在符合第一、二门限要求的BWP上进行数据发送, 可以理解为:多个BWP确定了BWP优先级,根据BWP优先级,来确定目标BWP进行数据发送。In actual application, the data transmission on the BWP that meets the first and second threshold requirements can be understood as: multiple BWPs determine the BWP priority, and the target BWP is determined to transmit data according to the BWP priority.
所述相应门限要求可以为规定的要求,或为通过网络下发获取的。The corresponding threshold requirement may be a prescribed requirement or obtained through network distribution.
相应预设时长(比如第一预设时长、第二预设时长、第三预设时长、第四预设时长)为规定的时长,或为通过网络下发获取的。The corresponding preset duration (for example, the first preset duration, the second preset duration, the third preset duration, and the fourth preset duration) is a specified duration, or is obtained through delivery through the network.
当所述终端在多个上行BWP上发送数据时,对于空闲态的终端,MSG1、MSG3可在获取信道资源的多个BWP上发送;相应地,当网络侧也在多个下行BWP上发送数据时,MSG2可在获取信道资源的多个BWP上发送;进一步地,对于MSG4,此时网络侧选择1个BWP发送BWP。网络的选择决定可以通过LBT成功率和/或干扰情况等等来确定(可以理解为依据BWP优先级排序来确定)。When the terminal sends data on multiple upstream BWPs, for idle terminals, MSG1 and MSG3 can send on multiple BWPs that acquire channel resources; accordingly, when the network side also sends data on multiple downlink BWPs At this time, MSG2 may send on multiple BWPs that acquire channel resources; further, for MSG4, at this time, the network selects one BWP to send the BWP. The network selection decision can be determined by the LBT success rate and / or interference situation, etc. (can be understood as determined according to the BWP priority ranking).
其中,多个BWP上发送的MSG3采用相同的终端标识(或小区无线网络临时标识(C-RNTI)),以便网络获知接收到的多个随机接入请求来自同一个终端。Among them, MSG3 sent on multiple BWPs use the same terminal identity (or cell radio network temporary identity (C-RNTI)), so that the network knows that the received multiple random access requests come from the same terminal.
在一实施例中,所述在第三预设时长内LBT成功率较高的多个BWP上进行数据发送时,该方法还可以包括:In an embodiment, when the data is sent on multiple BWPs with a high LBT success rate within the third preset duration, the method may further include:

实际应用时,网络也可以向所述终端下发下行BWP信息,以便所述终 端能够获知,进而能够及时接收网络发送的数据。In actual application, the network may also deliver downlink BWP information to the terminal, so that the terminal can learn, and thus can receive data sent by the network in time.
基于此,在一实施例中,该方法还可以包括:Based on this, in an embodiment, the method may further include:
接收网络下发的第二信令;所述第二信令用于指示接收下行数据的下行BWP信息。Receiving second signaling delivered by the network; the second signaling is used to indicate downlink BWP information for receiving downlink data.
这里,所述第二信令可以是RRC信令、广播(比如物理广播信道(PBCH)等)、系统消息等。Here, the second signaling may be RRC signaling, broadcasting (such as a physical broadcast channel (PBCH), etc.), system messages, and so on.
所述第二信令的内容包括以下至少之一:The content of the second signaling includes at least one of the following:
在一个下行BWP上进行数据接收;Receive data on a downstream BWP;
不在一个下行BWP上进行数据接收;Not receiving data on a downstream BWP;
在多个下行BWP上进行数据接收;Receive data on multiple downstream BWPs;
不在多个下行BWP上进行数据接收;Not receiving data on multiple downstream BWPs;
接收下行数据的BWP的数目;Number of BWP receiving downstream data;
接收下行数据的BWP索引。BWP index for receiving downstream data.
每个BWP的工作过程中,可以引入定时器或计数器,在定时器时长内或计数器的数值内没有进行数据发送(上行BWP)或数据接收(下行BWP)则进行BWP切换,比如可以根据BWP优先级顺序来进行BWP切换等。In the working process of each BWP, a timer or counter can be introduced. If there is no data transmission (upstream BWP) or data reception (downstream BWP) within the duration of the timer or the value of the counter, BWP switching is performed, for example, it can be prioritized according to BWP Perform BWP switching in order of level.
这里,定时器或计数器的时长可由网络侧来配置,比如可以通过系统消息(对于空闲态的终端)、RRC消息(对于连接态的终端)等。Here, the duration of the timer or counter can be configured by the network side, such as system messages (for the terminal in the idle state), RRC messages (for the terminal in the connected state), and so on.
所述定时器时长内或计数器的数值内没有进行数据接收(下行BWP)可以理解为:所述定时器时长内或计数器的数值内没有收到上行数据调度、和/或下行数据调度、和/或进行下行数据接收等。No data reception within the timer duration or counter value (downstream BWP) can be understood as: no uplink data scheduling, and / or downlink data scheduling, and / or downlink data scheduling, and / or are received within the timer duration or counter value Or receive downstream data, etc.
其中,实际应用时,在所述定时器或计数器运行过程中,可以判断是否接收到同步信号/物理广播信道块(SSB)、和/或其它参考符号判断没有接收到网络调度或下行数据是否是由于基站没有获取下行信道资源。如果终端接收到SSB和/或其它参考符号,那么BWP转换的计时器重新计时或计 数器重新计数。Among them, in actual application, during the operation of the timer or counter, it can be determined whether a synchronization signal / physical broadcast channel block (SSB) is received, and / or other reference symbols to determine whether network scheduling or downlink data is not received. Because the base station does not acquire downlink channel resources. If the terminal receives SSB and / or other reference symbols, the BWP-converted timer recounts or the counter recounts.
这里,对于连接态的终端,还可以利用RRC信令来通知终端是否被调度,以便帮助终端区分在一定时长内没有收到网络调度信息是由于网络没有调度终端,还是由于网络没能获取下行信道资源。如果终端接收到该RRC信令,则BWP转换的计时器重新计时或计数器重新计数。Here, for the connected terminal, RRC signaling can also be used to notify the terminal whether it is scheduled, so as to help the terminal distinguish whether the network scheduling information is not received within a certain period of time because the network does not schedule the terminal or the network fails to obtain the downlink channel Resources. If the terminal receives the RRC signaling, the timer converted by the BWP recounts or the counter recounts.
实际应用时,为了能够及时发送数据,当在相应BWP上一定时长内没有LBT成功时,需要进行BWP转换。In practice, in order to be able to send data in time, when there is no LBT success within a certain period of time on the corresponding BWP, a BWP conversion is required.
基于此,在一实施例中,在BWP上进行LBT时,该方法还可以包括以下之一:Based on this, in an embodiment, when LBT is performed on the BWP, the method may further include one of the following:
在第五预设时长内LBT没有成功,进行BWP转换;If LBT is not successful within the fifth preset time period, BWP conversion is performed;

在第六预设时长内LBT失败率达到第四门限,进行BWP转换;Within the sixth preset duration, the LBT failure rate reaches the fourth threshold, and BWP conversion is performed;
在第七预设时长内LBT成功率低于第五门限,终端进行BWP转换。The LBT success rate is lower than the fifth threshold within the seventh preset duration, and the terminal performs BWP conversion.
其中,实际应用时,可以设置定时器或计数器,在定时器时长内或计数器的数值内没有LBT成功,则进行BWP切换。Among them, in actual application, a timer or a counter can be set, and within the timer duration or the value of the counter without LBT success, BWP switching is performed.
