1、工作于非授权频谱的新空口(New Radio in Unlicensed Spectrum,NR-U)1. New air interface (New Radio in Unlicensed Spectrum, NR-U) working in unlicensed spectrum
在通信协议中,无线资源控制(Radio Resource Control,RRC)为媒体接入控制层(Media Access Control,MAC)实体配置一个持续性先听后说(Listen Before Talk,LBT)失败恢复程序(consistent LBT failure recovery procedure),若传输前执行了LBT检测,且检测到信道繁忙,则低层给MAC实体发送一个LBT失败指示(LBT failure indication)。In the communication protocol, Radio Resource Control (RRC) configures a persistent Listen Before Talk (LBT) failure recovery procedure (consistent LBT) for the Media Access Control (MAC) entity. failure recovery procedure), if LBT detection is performed before transmission and the channel is detected to be busy, the lower layer sends an LBT failure indication (LBT failure indication) to the MAC entity.
持续性LBT失败是基于每个BWP(for per UL BWP)的,由所有从低层到MAC实体的上行(Uplink,UL)传输的持续性LBT失败计数而产生。UE用于LBT失败计数的参数为LBT_COUNTER(基于每个服务小区(for per Serving Cell))。RRC在lbt-FailureRecoveryConfig为持续性LBT失败检测(consistent LBT failure detection)配置两个参数,即lbt-FailureInstanceMaxCount和lbt-FailureDetectionTimer。每当MAC实体收到一个低层的LBT failure indication,LBT_COUNTER计数加一。当LBT_COUNTER>=lbt-FailureInstanceMaxCount时,对服务小区的激活态上行带宽部分(active UL BWP)触发consistent LBT failure,然后,在服务小区的同载波上从该active UL BWP切换到另一个配置了物理随机接入信道(Physical Random Access Channel,PRACH)occasion,并且还未触发consistent LBT failure的UL BWP,在该UL BWP继续执行LBT。若服务小区的所有UL BWPs都触发了consistent LBT failure,则向高层指示consistent LBT failure。The persistent LBT failure is based on each BWP (for per UL BWP), which is generated by the continuous LBT failure count of all uplink (Uplink, UL) transmissions from the lower layer to the MAC entity. The parameter used by the UE for LBT failure counting is LBT_COUNTER (based on each serving cell (for per Serving Cell)). RRC configures two parameters for persistent LBT failure detection (consistent LBT failure detection) in lbt-FailureRecoveryConfig, namely lbt-FailureInstanceMaxCount and lbt-FailureDetectionTimer. Whenever the MAC entity receives a low-level LBT failure indication, the LBT_COUNTER count is incremented by one. When LBT_COUNTER>=lbt-FailureInstanceMaxCount, trigger consistent LBT failure on the active uplink bandwidth part (active UL BWP) of the serving cell, and then switch from the active UL BWP to another configured physical random on the same carrier of the serving cell Access channel (Physical Random Access Channel, PRACH) occasion, and has not triggered the UL BWP of consistent LBT failure, continue to perform LBT on this UL BWP. If all UL BWPs of the serving cell trigger consistent LBT failure, then indicate consistent LBT failure to the upper layers.
在通信协议中,eNB/gNB可以根据nodeB自身下行(Downlink,DL)信道接入,或UE根据UL信道接入发起信道占用共享(channel occupancy sharing)。eNB/gNB/UE可以通过信道接入优先级(Channel Access Priority Class,CAPC)(如表1所示)确定一个最大的COT。对于信道接入优先级p=3和p=4,若从长期来看能保证没有其它无线接入技术 (Radio Access Technology,RAT)共享此信道(如相关协议限制),T
m cot,p=10ms;否则,T

In the communication protocol, the eNB/gNB can access the downlink (DL) channel of the nodeB itself, or the UE can initiate channel occupancy sharing (channel occupancy sharing) based on the UL channel access. The eNB/gNB/UE can determine a maximum COT through Channel Access Priority Class (CAPC) (as shown in Table 1). For channel access priorities p=3 and p=4, if it can be guaranteed that no other radio access technology (Radio Access Technology, RAT) will share this channel in the long run (as restricted by relevant protocols), T m cot, p = 10 ms; otherwise, T m cot, p = 8 ms.

下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的资源重选方法进行详细地说明。The resource reselection method provided by the embodiment of the present application will be described in detail below through some embodiments and application scenarios with reference to the accompanying drawings.
通常,在UE与网络侧设备进行通信的过程中,网络侧设备可以为UE抢占非授权频谱资源,UE可以通过该非授权频谱资源,在一个信道占用时间内根据不同的信道接入模式与网络侧设备进行数据传输,从而实现UE与网络侧设备之间的通信。Usually, during the communication between the UE and the network side equipment, the network side equipment can seize unlicensed spectrum resources for the UE, and the UE can use the unlicensed spectrum resources to communicate with the network according to different channel access modes within a channel occupation time. The device on the network side performs data transmission, so as to realize the communication between the UE and the device on the network side.
然而,网络侧设备抢占的非授权频谱资源仅可以用于网络侧设备与UE之间的通信,UE之间无法采用网络侧设备抢占的非授权频谱资源进行通信,导致UE在非授权频谱上尝试获取传输资源时存在持续性LBT失败的情况,从而导致UE信道接入的成功率较低。However, the unlicensed spectrum resources seized by the network-side equipment can only be used for communication between the network-side equipment and the UE, and UEs cannot use the unlicensed spectrum resources seized by the network-side equipment for communication, causing the UE to try to There are persistent LBT failures when acquiring transmission resources, resulting in a low success rate of UE channel access.
为了解决上述技术问题,本申请实施例中,在UE在第一资源上执行LBT失败的情况下,UE可以根据目标信息确定第二资源,以在第二资源上执行LBT。其中,该目标信息包括以下至少一项:网络侧设备配置的资源、指示停止执行LBT的时长的计时器信息、资源类型信息、资源粒度重选概率。通过本方案,在UE在非授权频谱资源上尝试获取传输资源时执行LBT失败的情况下,UE可以根据目标信息重选合适的资源(即第二资源),以在该资源上执行LBT操作,并且,对于不同的目标信息,给出了确定重选资源的多种方式,保证了UE之间进行数据传输的通信需求,从而提高了UE信道接入的成功率。In order to solve the above technical problem, in the embodiment of the present application, when the UE fails to perform LBT on the first resource, the UE may determine the second resource according to the target information, so as to perform LBT on the second resource. Wherein, the target information includes at least one of the following: resources configured by the network side device, timer information indicating the duration of stopping the execution of LBT, resource type information, and resource granularity reselection probability. Through this solution, when the UE fails to perform LBT when trying to obtain transmission resources on unlicensed spectrum resources, the UE can reselect an appropriate resource (ie, the second resource) according to the target information to perform LBT operations on the resource, Moreover, for different target information, multiple ways of determining reselection resources are given, which ensures the communication requirements for data transmission between UEs, thereby improving the success rate of UE channel access.
需要说明的是,在非授权频谱上,UE可以基于不同的资源选择颗粒度进行资源选择,例如,基于载波(carrier)进行资源选择、或者基于带宽部分(Bandwidth Part,BWP)进行资源选择、或者基于资源池(resource pool)进行资源选择。UE根据自己的终端能力,可以支持其在非授权频谱上的一个或多个载波上进行旁链路(Sidelink,SL)传输。进一步地,一个载波可以包含一个或多个带宽部分,且一个带宽部分可以包含一个或多个资源池。It should be noted that on the unlicensed spectrum, the UE can perform resource selection based on different resource selection granularities, for example, perform resource selection based on carrier (carrier), or perform resource selection based on bandwidth part (Bandwidth Part, BWP), or Resource selection based on resource pool. According to its own terminal capabilities, the UE can support sidelink (Sidelink, SL) transmission on one or more carriers on the unlicensed spectrum. Further, one carrier may include one or more bandwidth parts, and one bandwidth part may include one or more resource pools.

步骤204、UE接收网络侧设备发送的第二消息,在第二消息中未包括配置信息、且第二消息指示允许UE执行LBT资源重选的情况下,将第四资源确定为第二资源。Step 204, the UE receives the second message sent by the network side device, and determines the fourth resource as the second resource when the second message does not include configuration information and the second message indicates that the UE is allowed to perform LBT resource reselection.
本申请实施例中,上述第四资源为未触发连续LBT失败的资源。In this embodiment of the present application, the above fourth resource is a resource that does not trigger continuous LBT failure.
需要说明的是,未触发连续LBT失败的资源可以理解为:触发LBT失败的频率较低的资源,或者,尚未触发LBT失败的资源。It should be noted that resources that do not trigger continuous LBT failures may be understood as: resources that trigger LBT failures with low frequency, or resources that have not yet triggered LBT failures.
本申请实施例中,一种实现方式中,UE可以将网络侧设备预配置的资源确定为第二资源;另一种实现方式中,UE可以将网络侧设备当前配置的资源(即第三资源)确定为第二资源;又一种实现方式中,UE可以根据网络侧设备指示允许UE执行LBT资源重选的消息,将未触发连续LBT失败的资源确定为第二资源。In the embodiment of this application, in one implementation manner, the UE may determine the resources pre-configured by the network side device as the second resource; in another implementation manner, the UE may determine the resources currently configured by the network side device (that is, the third resource ) is determined as the second resource; in yet another implementation manner, the UE may determine resources that do not trigger continuous LBT failures as the second resource according to a message from the network side device indicating that the UE is allowed to perform LBT resource reselection.

需要说明的是,UE在第一资源上执行LBT失败的频率可以理解为:UE执行LBT失败的次数占UE执行LBT的总次数的比重。例如,若UE在第一资源上执行10次LBT,其中存在8次LBT失败,则UE在第一资源上执行LBT失败的频率为0.8。It should be noted that the frequency at which the UE fails to perform LBT on the first resource may be understood as: the number of times that the UE fails to perform LBT accounts for the total number of times that the UE performs LBT. For example, if the UE performs LBT 10 times on the first resource, and there are 8 LBT failures, the frequency of failure of the UE to perform LBT on the first resource is 0.8.
可以理解,UE在第一资源上执行LBT失败的频率越高,说明第一资源不可用,需要重选合适的资源。It can be understood that the higher the frequency of failure of the UE to perform LBT on the first resource, it means that the first resource is unavailable, and a suitable resource needs to be reselected.

需要说明的是,由于专用资源和非授权频谱资源相对不容易获取,因此,UE通常优先使用专用资源或非授权频谱资源。It should be noted that, since the dedicated resources and the unlicensed spectrum resources are relatively difficult to obtain, the UE usually preferentially uses the dedicated resources or the unlicensed spectrum resources.
本申请实施例中,第一资源可以为第一类型资源,即UE在高优先级的资源上执行LBT失败的情况下,可以重选至低优先级的资源,以在该低优先级的资源上执行LBT操作,保 证了UE之间进行数据传输的通信需求,从而提高了UE信道接入的成功率。In this embodiment of the present application, the first resource may be the first type of resource, that is, if the UE fails to perform LBT on the high-priority resource, it may reselect to the low-priority resource, so that the low-priority resource The LBT operation is performed on the network to ensure the communication requirements for data transmission between UEs, thereby improving the success rate of UE channel access.

步骤405、UE接收网络侧设备发送的资源类型信息。Step 405, the UE receives the resource type information sent by the network side device.
本申请实施例中,由于网络侧设备为UE配置了第一类型资源和第二类型资源,因此,UE在第一类型资源或第二类型资源上执行LBT失败时,可以重选至第二类型资源(即低优先级的资源),以在该第二类型资源上执行LBT操作,保证了UE之间进行数据传输的通信需求,从而提高了UE信道接入的成功率。In the embodiment of this application, since the network side device configures the first type resource and the second type resource for the UE, when the UE fails to perform LBT on the first type resource or the second type resource, it can reselect to the second type resource. resources (that is, resources with low priority), so that the LBT operation is performed on the second-type resources to ensure the communication requirements for data transmission between UEs, thereby improving the success rate of UE channel access.

In addition, when the UE is within the coverage of the network side device, the resource type used for sidelink transmission may also be a licensed spectrum type or an unlicensed spectrum type. Taking the UE at the resource pool resource level as an example below, the third implementation manner will be described in detail.
1)网络侧设备为UE配置了专用resource pool和共享resource pool,UE优先使用专用resource pool:1) The network side device configures a dedicated resource pool and a shared resource pool for the UE, and the UE preferentially uses the dedicated resource pool:
A)若UE在网络侧设备配置的专用resource pool上触发持续性LBT失败,则UE向网络侧设备上报在专用resource pool上执行LBT失败,并从该专用resource pool重选至共享resource pool。A) If the UE fails to trigger persistent LBT on the dedicated resource pool configured by the network side device, the UE reports to the network side device that the execution of LBT on the dedicated resource pool fails, and reselects from the dedicated resource pool to the shared resource pool.

在第四种实施方式中,在上述目标信息包括资源粒度重选概率的情况下,UE根据目标信息确定第二资源的方法可以包括下述的步骤501或步骤502。In the fourth implementation manner, in the case that the target information includes resource granularity reselection probability, the method for the UE to determine the second resource according to the target information may include the following step 501 or step 502 .
步骤501、在资源粒度重选概率满足预设条件的情况下,UE将第七资源确定为第二资源。Step 501, when the resource granularity reselection probability satisfies a preset condition, the UE determines the seventh resource as the second resource.
本申请实施例中,上述第七资源为未触发连续LBT失败的资源。In the embodiment of the present application, the above-mentioned seventh resource is a resource that does not trigger continuous LBT failure.
可选地,本申请实施例中,上述资源粒度重选概率可以为第一资源对应的资源粒度重选概率。Optionally, in this embodiment of the present application, the resource granularity reselection probability may be the resource granularity reselection probability corresponding to the first resource.
可选地,本申请实施例中,资源粒度重选概率满足预设条件是指:与资源粒度重选概率相关的随机数落在资源重选概率的范围内。示例性地,假设资源粒度重选概率为30%,若随机数落在了【0,30】内,则UE需要重选资源。Optionally, in this embodiment of the present application, the resource granularity reselection probability meets a preset condition means that the random number related to the resource granularity reselection probability falls within the range of the resource reselection probability. Exemplarily, assuming that the resource granularity reselection probability is 30%, if the random number falls within [0, 30], the UE needs to reselect resources.
需要说明的是,未触发连续LBT失败的资源可以理解为:触发LBT失败的频率较低的资源,或者,尚未触发LBT失败的资源。It should be noted that resources that do not trigger continuous LBT failures may be understood as: resources that trigger LBT failures with low frequency, or resources that have not yet triggered LBT failures.
步骤502、在资源粒度重选概率不满足预设条件的情况下,UE将第一资源确定为第二资源。Step 502, when the resource granularity reselection probability does not meet the preset condition, the UE determines the first resource as the second resource.
示例性地,假设资源粒度重选概率为30%,若随机数落在了【30,100】外,则UE不 执行资源重选,仍在当前资源上执行LBT操作。For example, assuming that the resource granularity reselection probability is 30%, if the random number falls outside [30, 100], the UE does not perform resource reselection, and still performs LBT operation on the current resource.
本申请实施例中,UE可以根据资源粒度重选概率,决定是否重选资源,以在第一资源或重选的资源上执行LBT操作,保证了UE之间进行数据传输的通信需求,从而提高了UE信道接入的成功率。In the embodiment of the present application, the UE can decide whether to reselect resources according to the resource granularity reselection probability, so as to perform LBT operation on the first resource or the reselected resource, so as to ensure the communication requirements for data transmission between UEs, thereby improving The success rate of UE channel access is improved.
在此实施方式中,网络侧设备可以根据UE的能力,为UE配置在非授权频谱上可以进行传输的SL carrier,以及SL carrier上的多个SL BWPs,而每个SL BWP上可以配置多个SL resource pools。网络侧设备可以选择是否为UE(预)配置BWP重选概率和/或resource pool重选概率。根据不同的资源颗粒度,UE根据资源重选概率可以执行资源重选或者上报持续性LBT失败。比如,若网络侧设备(预)配置了BWP重选概率/resource pool重选概率,则UE可以在触发持续性LBT失败的时候,根据BWP重选概率/resource pool重选概率判断是否执行BWP重选/resource pool重选。若网络侧设备未配置BWP重选概率/resource pool重选概率,则UE可以自主重选BWP,直到SL carrier上的所有SL BWP都触发持续性LBT失败,UE才向网络侧设备上报持续性LBT失败。下面以UE在resource pool资源级别为例,对第四种实施方式进行具体说明。In this embodiment, the network side device can configure for the UE an SL carrier that can transmit on the unlicensed spectrum and multiple SL BWPs on the SL carrier according to the capabilities of the UE, and each SL BWP can be configured with multiple SL resource pools. The network side device can choose whether to (pre)configure BWP reselection probability and/or resource pool reselection probability for UE. According to different resource granularities, UE can perform resource reselection or report persistent LBT failure according to resource reselection probability. For example, if the network-side device (pre) configures the BWP reselection probability/resource pool reselection probability, the UE can determine whether to perform BWP reselection according to the BWP reselection probability/resource pool reselection probability when triggering persistent LBT fails. Select /resource pool to re-elect. If the BWP reselection probability/resource pool reselection probability is not configured on the network side device, the UE can reselect BWP independently, and the UE will not report the persistent LBT to the network side device until all SL BWPs on the SL carrier trigger persistent LBT failure fail. The fourth implementation manner will be specifically described below by taking the UE at the resource pool resource level as an example.
