在5GNR(New Radio,新空口)中,用户设备进行侧行链路通信时,选择传输资源主要有两种模式:第一种模式为用户设备获取网络设备配置的传输资源,以通过该传输资源进行侧行链路上的数据发送;第二种模式为用户设备在资源池中随机选择传输资源。以第二种模式为例,用户设备进行资源选择或重选时,可以确定一个资源集合,然后根据监听到的第一侧行控制信息以及未侦听时隙对上述资源集合执行资源排除机制,获得候选资源集合,避免与其他用户设备产生资源冲突。In 5GNR (New Radio, New Radio), when user equipment performs sidelink communication, there are two main modes for selecting transmission resources: The first mode is for the user equipment to obtain the transmission resources configured by the network device to use the transmission resources. Perform data transmission on the sidelink; the second mode is for the user equipment to randomly select transmission resources in the resource pool. Taking the second mode as an example, when the user equipment selects or reselects resources, it can determine a resource set, and then perform a resource exclusion mechanism on the above resource set based on the monitored first sideline control information and unlistened time slots. Obtain a set of candidate resources to avoid resource conflicts with other user devices.
用户设备在非授权频段进行通信时,需要对选择的传输资源执行LBT检测。传统方法中,用户设备进行LBT时,首先监听时长为Td的时间段内的信道,在监听到该时间段内所有监听时隙均为空闲之后,再执行退避流程进行检测;在上述检测过程中其中一个监测时隙为忙碌,则LBT失败。若LBT失败则无法使用该传输资源进行数据传输。When user equipment communicates in an unlicensed frequency band, it needs to perform LBT detection on the selected transmission resources. In the traditional method, when the user equipment performs LBT, it first monitors the channel within the time period of Td. After monitoring that all monitoring time slots in this time period are idle, it then performs the backoff process for detection; in the above detection process If one of the monitoring time slots is busy, LBT fails. If LBT fails, the transmission resource cannot be used for data transmission.
针对以上问题,本申请实施例提供一种传输资源的选择方法,可以解决用户设备在选择传输资源之后,LBT检测成功率低导致不能进行数据传输的问题。In response to the above problems, embodiments of the present application provide a transmission resource selection method, which can solve the problem that after the user equipment selects the transmission resource, the LBT detection success rate is low and data transmission cannot be performed.

用户设备触发资源选择或重选的情况下,可以根据资源选择或重选的触发时隙确定一个资源选择窗以及一个侦听窗口,并将资源选择窗对应的资源确定为一个资源集合;进一步地,用户设备可以根据侦听窗口确定用户设备的非侦听时隙,以及其他用户设备发送的第一侧行控制信息,进而基于上述非侦听时隙和第一侧行控制信息对资源集合执行排除机制,获得候选资源集合。When the user equipment triggers resource selection or reselection, a resource selection window and a listening window can be determined according to the triggering time slot of resource selection or reselection, and the resources corresponding to the resource selection window are determined as a resource set; further , the user equipment can determine the non-listening time slot of the user equipment according to the listening window and the first sideline control information sent by other user equipment, and then execute the resource set based on the above-mentioned non-listening time slot and the first sideline control information. Exclude the mechanism to obtain a set of candidate resources.
其他用户设备执行LBT,成功接入信道之后,其占用信道的时间可以成为信道占用时间(Channel Occupancy Time,简称COT)。用户设备对应的COT具有最大时长限制,上述最大时长与该用户设备的信道接入优先级相关。其他用户设备可能不需要在其对应的COT内持续进行数据传输,可以通过发送COT信息共享资源。同一个用户设备发送的COT信息可以被一个用户设备接收,也可以被多个用户设备接收,在此不做限定。When other user equipment performs LBT and successfully accesses the channel, the time it occupies the channel can become the Channel Occupancy Time (COT). The COT corresponding to the user equipment has a maximum duration limit, and the above maximum duration is related to the channel access priority of the user equipment. Other user equipment may not need continuous data transmission within its corresponding COT and can share resources by sending COT information. The COT information sent by the same user equipment can be received by one user equipment or by multiple user equipments, which is not limited here.
用户设备可以收集到一个设备发送的COT信息,也可以收集到多个设备发送的COT信息,在此不做限定。The user device can collect COT information sent by one device or can collect COT information sent by multiple devices, which is not limited here.
用户设备在获取候选资源集合以及收集到的COT信息之后,可以根据收集到的COT信息对候选资源集合进行处理,获得第一资源集合。上述第一资源集合中的资源可以是候选资源集合与上述COT信息指示的资源范围的交集,也可以是候选资源集合与上述COT信息指示的资源范围的交集的一个子集,在此不做限定。After obtaining the candidate resource set and the collected COT information, the user equipment can process the candidate resource set according to the collected COT information to obtain the first resource set. The resources in the first resource set may be the intersection of the candidate resource set and the resource range indicated by the COT information, or a subset of the intersection of the candidate resource set and the resource range indicated by the COT information, which is not limited here. .
在一种实现方式中,用户设备可以根据COT信息对候选资源集合进行筛选,获得第一资源集合。用户设备可以根据收集到的各个COT信息对候选资源集合进行筛选,也可以根据收集到的其中一个COT信息对候选资源集合进行筛选,在此不做限定。用户设备可以根据收集到的COT信息确定COT信息指示的资源范围,然后将确定上述资源范围与上述候选资源集合的交集,获得第一资源集合。或者,用户设备可以针对候选资源集合中的各个资源,确定其是否位于COT信息指示的资源范围内,然后将落入上述资源范围内的资源组成第一资源集合。In an implementation manner, the user equipment can filter the candidate resource set according to the COT information to obtain the first resource set. The user equipment can filter the candidate resource set according to each collected COT information, or can filter the candidate resource set according to one of the collected COT information, which is not limited here. The user equipment may determine the resource range indicated by the COT information based on the collected COT information, and then determine the intersection of the resource range and the candidate resource set to obtain the first resource set. Alternatively, the user equipment may determine whether each resource in the candidate resource set is within the resource range indicated by the COT information, and then form the first resource set with the resources falling within the resource range.
在另一种实现方式中,用户设备根据COT信息对候选资源集合进行筛选之前,可以先对COT信息的可用性进行判断。用户设备可以确定收集到的COT信息中是否包含可用COT信息,若是,则根据可用COT信息对候选资源集合进行筛选,获得第一资源集合。上述可用COT信息可以是指COT信息指示的资源范围中包含的空闲资源数量大于或等于预设阈值的COT信息,也可以是根据COT信息指示的信道接入优先级进行判断获得的。可选地,上述可用COT信息指示的信道接入优先级可以小于或等于用户设备的信道接入优先级。In another implementation manner, before the user equipment filters the candidate resource set according to the COT information, the user equipment may first determine the availability of the COT information. The user equipment can determine whether the collected COT information contains available COT information, and if so, filter the candidate resource set according to the available COT information to obtain the first resource set. The above available COT information may refer to COT information in which the number of idle resources included in the resource range indicated by the COT information is greater than or equal to the preset threshold, or may be obtained by judgment based on the channel access priority indicated by the COT information. Optionally, the channel access priority indicated by the available COT information may be less than or equal to the channel access priority of the user equipment.
S104、从第一资源集合中随机选择传输资源。S104. Randomly select transmission resources from the first resource set.
在上述步骤的基础上,用户设备可以从第一资源集合中随机选择传输资源。Based on the above steps, the user equipment may randomly select transmission resources from the first resource set.
由于第一资源集合中的资源是基于COT信息确定的,用户设备选择其他用户设备共享的资源进行LBT时,可以通过监听固定长度的信道完成LBT检测。例如,上述监听时长可以是Tshort(可以25微秒是),如果Tshort内的监听时隙均为空闲,则用户设备可以通过该传输资源进行数据传输。另一种LBT方式中,上述监听设备可以是Tf(可以是16微秒),如果Tf内的监听时隙均为空闲,则用户设 备可以通过该传输资源进行数据传输。在另一种LBT方式中,用户设备可以不进行LBT直接接入信道,该类型可以应用于此次传输距离上次传输的时间间隔小于或等于16微秒的情况。Since the resources in the first resource set are determined based on the COT information, when the user equipment selects resources shared by other user equipment for LBT, the LBT detection can be completed by monitoring a fixed-length channel. For example, the above listening duration can be Tshort (can be 25 microseconds). If all the listening time slots within Tshort are idle, the user equipment can transmit data through the transmission resource. In another LBT method, the above-mentioned monitoring device can be Tf (can be 16 microseconds). If the monitoring time slots in Tf are all idle, the user equipment can transmit data through this transmission resource. In another LBT method, the user equipment can directly access the channel without performing LBT. This type can be applied when the time interval between this transmission and the last transmission is less than or equal to 16 microseconds.
若用户设备未收集到COT信息,或收集到的COT信息中不包含可用COT信息,则从候选资源集合中随机选择传输资源。If the user equipment does not collect COT information, or the collected COT information does not include available COT information, the transmission resource is randomly selected from the candidate resource set.
用户设备可以针对所选择的传输资源进行LBT检测,在LBT成功的情况下通过该传输资源进行数据传输。The user equipment can perform LBT detection on the selected transmission resource and perform data transmission through the transmission resource if LBT is successful.
需要说明的是,用户设备是否从第一资源集合中随机选择传输资源取决于用户设备实现。例如,用户设备可以在获得第一资源集合之后,选择从候选资源集合中随机选择传输资源。另外,用户设备可以具备基于候选资源集合和COT信息获取第一资源集合的能力,在接收到COT信息之后是否获取上述第一资源集合取决于用户设备实现。It should be noted that whether the user equipment randomly selects transmission resources from the first resource set depends on the user equipment implementation. For example, after obtaining the first resource set, the user equipment may choose to randomly select transmission resources from the candidate resource set. In addition, the user equipment may have the ability to obtain the first resource set based on the candidate resource set and COT information. Whether to obtain the first resource set after receiving the COT information depends on the user equipment implementation.
上述传输资源的选择方法,用户设备从第一资源集合中随机选择传输资源;其中,上述第一资源集合为用户设备基于候选资源集合以及收集到的信道占用时间COT信息确定的。用户设备在进行资源选择或重选时,在获得候选资源集合之后增加了确定第一资源集合的步骤,进而可以在第一资源集合中随机选择传输资源。由于上述第一资源集合是基于候选资源集合以及收集到的COT信息确定的,上述COT信息为其他用户设备进行LBT检测成功后共享的,基于此,用户设备可以共享其他用户设备的资源,提高了资源利用率。另外,用户设备通过其他用户设备共享的资源进行数据传输,还可以避免其他用户设备在非授权频段上数据传输中断时导致资源被WiFi用户抢占,提高了其他用户设备进行非授权频段通信的可靠性。进一步地,用户设备基于其他用户设备共享的资源进行LBT检测时,上述共享资源被监听为空闲资源的概率较高,从而可以提高LBT成功率;用户设备选择其它用户设备共享的资源的情况下,可以采用监听固定时长的方式进行LBT检测,对应的监听时长较短,进一步提高LBT成功率。In the above transmission resource selection method, the user equipment randomly selects transmission resources from the first resource set; wherein the first resource set is determined by the user equipment based on the candidate resource set and the collected channel occupancy time COT information. When the user equipment performs resource selection or reselection, the user equipment adds a step of determining the first resource set after obtaining the candidate resource set, and then can randomly select transmission resources in the first resource set. Since the above first resource set is determined based on the candidate resource set and the collected COT information, the above COT information is shared by other user equipment after successful LBT detection. Based on this, the user equipment can share the resources of other user equipment, which improves Resource utilization. In addition, user equipment transmits data through resources shared by other user equipment, which can also prevent other user equipment from causing resource preemption by WiFi users when data transmission on the unlicensed frequency band is interrupted, improving the reliability of other user equipment's communication in the unlicensed frequency band. . Furthermore, when the user equipment performs LBT detection based on resources shared by other user equipment, the probability that the above shared resources are monitored as idle resources is relatively high, thereby improving the LBT success rate; when the user equipment selects resources shared by other user equipment, LBT detection can be performed by monitoring for a fixed duration, and the corresponding monitoring duration is shorter, further improving the LBT success rate.
上述实施例中主要介绍了用户设备在获取候选资源集合之后,可以根据候选资源集合以及收集到的COT信息获取第一资源集合,通过从第一资源集合中随机选择传输资源,提高用户设备在非授权频段进行数据传输时的LBT成功率。上述第一资源集合的获取过程可以在用户设备中的物理层实现,也可以在用户设备中的高层实现,下述实施例针对不同的实现方式进行具体说明。The above embodiment mainly introduces that after the user equipment obtains the candidate resource set, it can obtain the first resource set according to the candidate resource set and the collected COT information, and randomly selects transmission resources from the first resource set to improve the user equipment's performance in non-operational situations. LBT success rate when transmitting data in licensed frequency bands. The above-mentioned acquisition process of the first resource set may be implemented at the physical layer in the user equipment, or may be implemented at a high level in the user equipment. The following embodiments will specifically describe different implementation methods.
在一个实施例中,上述第一资源集合为用户设备的高层基于物理层上报的COT信息对物理层上报的候选资源集合进行筛选获得的。In one embodiment, the first resource set is obtained by the higher layer of the user equipment filtering the candidate resource set reported by the physical layer based on the COT information reported by the physical layer.
用户设备的物理层可以向高层上报候选资源集合以及COT信息。物理层向高层上报的COT信息可以是一个,也可以是多个。用户设备收集到的所有COT信息,也可以是部分COT信息,在此不做限定。The physical layer of the user equipment can report the candidate resource set and COT information to the higher layer. The COT information reported by the physical layer to the higher layer can be one or multiple. All COT information collected by the user equipment can also be part of the COT information, which is not limited here.
可选的,物理层向高层上报的COT信息为用户设备收集到的COT信息。Optionally, the COT information reported by the physical layer to the higher layer is the COT information collected by the user equipment.
可选的,物理层向高层上报的COT信息为收集到的COT信息中的可用COT信息。用户设备的物理层可以根据COT信息指示的信道接入优先级,将信道接入优先级低于或等于用户设备的信道接入优先级的COT信息确定为可用COT信息,然后将各个可用COT信息上报至高层。Optionally, the COT information reported by the physical layer to the higher layer is the available COT information among the collected COT information. The physical layer of the user equipment can determine the COT information whose channel access priority is lower than or equal to the channel access priority of the user equipment as available COT information based on the channel access priority indicated by the COT information, and then use each available COT information Report to senior management.
可选的,物理层向高层上报的COT信息为收集到的COT信息中的其中一个可用COT信息。其中,用户设备的物理层可以在收集到的多个COT信息中选择一个可用COT信息。用户设备在多个COT信息中选择其中一个可用COT信息时,可以随机选择,也可以按照接收COT信息的顺序确定。可选的,上述其中一个可用COT信息为满足预设第一条件的可用COT信息。上述第一条件可以是COT信息指示的信道接入优先级最高,也可以是COT信息指示的信道接入优先级最低,还可以是COT信息中指示的资源数量最多。可选的,第一条件为COT信息指示范围的剩余时长最长;剩余时长为COT信息对应的结束时隙与当前时隙之间的时长。Optionally, the COT information reported by the physical layer to the higher layer is one of the available COT information among the collected COT information. Among them, the physical layer of the user equipment can select one available COT information from the multiple collected COT information. When the user equipment selects one of the available COT information among multiple COT information, it can select it randomly or according to the order in which the COT information is received. Optionally, one of the above available COT information is the available COT information that satisfies the preset first condition. The above first condition may be that the channel access priority indicated by the COT information is the highest, or that the channel access priority indicated by the COT information is the lowest, or that the number of resources indicated in the COT information is the largest. Optionally, the first condition is that the remaining duration of the range indicated by the COT information is the longest; the remaining duration is the duration between the end time slot corresponding to the COT information and the current time slot.
上述传输资源的选择方法,用户设备通过高层对候选资源集合进行筛选,使得用户设备可以从其他用户设备共享的资源中随机选择传输资源,提高LBT成功率。In the above transmission resource selection method, the user equipment filters the candidate resource set through the high layer, so that the user equipment can randomly select transmission resources from resources shared by other user equipment, thereby improving the LBT success rate.
用户设备的物理层向高层上报的COT信息不同的情况下,其对应的第一资源集合的获取方式也可以不同。下面实施例中对用户设备的高层获取第一资源集合的方式进行具体介绍。When the COT information reported by the physical layer of the user equipment to the higher layer is different, the corresponding first resource set may be obtained in different ways. In the following embodiments, the manner in which the upper layer of the user equipment obtains the first resource set is specifically introduced.
在一个实施例中,物理层向高层上报的COT信息为用户设备收到的COT信息,或者收集到的COT信息中的可用COT信息的情况下,高层收到的COT信息可以是一个或多个。用户设备获取第一资源集合的方式可以参见图3,上述S102包括:In one embodiment, when the COT information reported by the physical layer to the higher layer is the COT information received by the user equipment, or the available COT information in the collected COT information, the COT information received by the higher layer may be one or more . The way in which the user equipment obtains the first resource set can be seen in Figure 3. The above S102 includes:
S202、通过高层在物理层上报的COT信息中选择其中一个可用COT信息。S202: Select one of the available COT information from the COT information reported by the physical layer through the upper layer.
用户设备通过高层选择其中一个可用COT信息的方式可以参见上述实施例中,物理层选择其中一个可用COT信息的方式。其中,用户设备的高层可以在物理层上报的一个或多个COT信息中选择一个可用COT信息。用户设备的高层选择其中一个可用COT信息时,可以随机选择,也可以按照接收COT信息的顺序确定。可选的,上述其中一个可用COT信息为满足预设第一条件的可用COT信息。上述第一条件可以是COT信息指示的信道接入优先级最高,也可以是COT信息指示的信道接入优先级最低,还可以是COT信息中指示的资源数量最多。可选的,第一条件为COT信息指示范围的剩余时长最长;剩余时长为COT信息对应的结束时隙与当前时隙之间的时长。The way in which the user equipment selects one of the available COT information through the higher layer can refer to the way in which the physical layer selects one of the available COT information in the above embodiment. Among them, the upper layer of the user equipment can select one available COT information from one or more COT information reported by the physical layer. When the higher layer of the user equipment selects one of the available COT information, it can be selected randomly or determined in the order in which the COT information is received. Optionally, one of the above available COT information is the available COT information that satisfies the preset first condition. The above first condition may be that the channel access priority indicated by the COT information is the highest, or that the channel access priority indicated by the COT information is the lowest, or that the number of resources indicated in the COT information is the largest. Optionally, the first condition is that the remaining duration of the range indicated by the COT information is the longest; the remaining duration is the duration between the end time slot corresponding to the COT information and the current time slot.
S204、在候选资源集合中,将其中一个可用COT信息指示的COT范围内的候选资源组成第一资源集合。S204. In the candidate resource set, combine one of the candidate resources within the COT range indicated by the available COT information into a first resource set.
用户设备的高层在选择一个可用COT信息之后,可以将该COT信息指示的COT范围内的候选资源,组成第一资源集合。After the higher layer of the user equipment selects an available COT information, the candidate resources within the COT range indicated by the COT information may form a first resource set.
以用户设备UE1为例,UE1的物理层向高层上报的COT信息包括用户设备UE2和用户设备UE3发送的COT信息。UE1的物理层向高层上报的候选资源集合A可以包括图4中斜线阴影部分的资源。UE2发送的COT信息指示的COT范围如图中的资源集合2,UE3发送的COT信息指示的COT范围如图中的资源集合3,由于UE2发送的COT信息的剩余时长大于UE3发送的COT信息的剩余时长,用户设备的高层可以选择UE2发送的COT信息对候选资源集合进行筛选,将资源集合2中的候选资源组成第一资源集合,如图5中所示的方格阴影部分的资源。Taking user equipment UE1 as an example, the COT information reported by the physical layer of UE1 to the higher layer includes COT information sent by user equipment UE2 and user equipment UE3. The candidate resource set A reported by the physical layer of UE1 to the higher layer may include the resources in the diagonally shaded area in Figure 4 . The COT range indicated by the COT information sent by UE2 is resource set 2 in the figure, and the COT range indicated by the COT information sent by UE3 is resource set 3 in the figure. Since the remaining duration of the COT information sent by UE2 is longer than that of the COT information sent by UE3 During the remaining time, the higher layer of the user equipment can select the COT information sent by UE2 to filter the candidate resource set, and form the first resource set from the candidate resources in resource set 2, such as the resources in the shaded part of the square as shown in Figure 5.
上述传输资源的选择方法,用户设备通过高层选择一个COT信息对候选资源集合进行筛选,可以提高第一资源集合的获取效率;进一步地,用户设备选择剩余时长最长的COT信息,可以使得用户设备可选择的传输资源较多,增大了选择空闲资源的概率。In the above transmission resource selection method, the user equipment selects a COT information through the high layer to filter the candidate resource set, which can improve the acquisition efficiency of the first resource set; further, the user equipment selects the COT information with the longest remaining time, which can make the user equipment There are many transmission resources to choose from, which increases the probability of selecting idle resources.
在其中一个实施例中,物理层向高层上报的COT信息为用户设备收到的COT信息,或者收集到的COT信息中的可用COT信息的情况下,高层收到的COT信息可以是一个或多个。用户设备的高层可以根据接收到的COT信息分别对候选资源集合进行筛选,将候选资源集合中各可用COT信息指示的COT范围内的候选资源组成第一资源集合。In one embodiment, when the COT information reported by the physical layer to the higher layer is the COT information received by the user equipment, or the available COT information in the collected COT information, the COT information received by the higher layer may be one or more indivual. The higher layer of the user equipment can respectively filter the candidate resource set according to the received COT information, and form the first resource set from the candidate resources within the COT range indicated by each available COT information in the candidate resource set.
以图4中的用户设备UE1为例。用户设备UE1可以将资源集合2中的候选资源,以及资源集合3中的候选资源,共同组成第一资源集合,如图6中所示的方格阴影部分的资源。Take the user equipment UE1 in Figure 4 as an example. The user equipment UE1 may combine the candidate resources in the resource set 2 and the candidate resources in the resource set 3 to form a first resource set, such as the resources in the square shaded portion as shown in Figure 6 .
上述传输资源的选择方法,用户设备通过多个COT信息对候选资源集合进行筛选,从而可以采用多个用户设备共享的资源进行数据传输,由于不同用户设备共享的资源对应的频率范围不同,采用上述方法可以提高用户设备的可用带宽。In the above transmission resource selection method, the user equipment filters the candidate resource set through multiple COT information, so that the resources shared by multiple user equipments can be used for data transmission. Since the resources shared by different user equipments correspond to different frequency ranges, the above-mentioned Methods can increase the available bandwidth of user devices.
在其中一个实施例中,物理层向高层上报的COT信息为收集到的COT信息中的其中一个可用COT信息。高层获取物理层上报的一个可用COT信息之后,可以将该候选资源集合中其中一个可用COT信息指示的COT范围内的候选资源组成第一资源集合。In one embodiment, the COT information reported by the physical layer to the higher layer is one of the available COT information among the collected COT information. After the upper layer obtains an available COT information reported by the physical layer, the candidate resources in the candidate resource set within the COT range indicated by one of the available COT information can form a first resource set.
如图7所示,用户设备UE1的高层接收到的COT信息为用户设备UE2发送的COT信息,UE1可以将该COT信息指示的范围资源集合2中的候选资源,组成第一资源集合,如图中的方格阴影部分所示的资源。As shown in Figure 7, the COT information received by the upper layer of the user equipment UE1 is the COT information sent by the user equipment UE2. The UE1 can use the candidate resources in the range resource set 2 indicated by the COT information to form the first resource set, as shown in Figure Resources indicated by the shaded squares in .
上述传输资源的选择方法,用户设备中的高层获取物理层上报的一个COT信息,可以直接基于该COT信息对候选资源集合进行筛选,使得用户设备可以随机选择其他用户设备共享的资源,提高了LBT成功率。In the above transmission resource selection method, the higher layer in the user equipment obtains a COT information reported by the physical layer, and can directly filter the candidate resource set based on the COT information, so that the user equipment can randomly select resources shared by other user equipment, improving LBT Success rate.
上述各实施例中分别介绍了用户设备的物理层将候选资源集合以及COT信息上报至高层,通过高层获取第一资源集合的方式。下面实施例中介绍用户设备的物理层获取第一资源集合的方式。Each of the above embodiments respectively introduces the method in which the physical layer of the user equipment reports the candidate resource set and COT information to the higher layer, and obtains the first resource set through the higher layer. The following embodiments introduce how the physical layer of the user equipment obtains the first resource set.
在一个实施例中,第一资源集合为用户设备的物理层基于候选资源集合以及COT信息获得的。物理层可以根据一个COT信息确定第一资源集合,也可以根据多个COT信息确定第一资源集合,在此不做限定。In one embodiment, the first resource set is obtained by the physical layer of the user equipment based on the candidate resource set and COT information. The physical layer may determine the first resource set based on one COT information, or may determine the first resource set based on multiple COT information, which is not limited here.
在一种实现方式中,用户设备的物理层可以根据一个COT信息对候选资源集合进行筛选,获得第一资源集合,如图8所示,上述S102包括:In one implementation, the physical layer of the user equipment can filter the candidate resource set based on a piece of COT information to obtain the first resource set. As shown in Figure 8, the above S102 includes:
S302、通过物理层在收集到的COT信息中选择其中一个可用COT信息。S302: Select one of the available COT information from the collected COT information through the physical layer.
用户设备的物理层从多个COT信息中选择一个COT信息的方式,可以参见上述实施例。用户设备在多个COT信息中选择其中一个可用COT信息时,可以随机选择,也可以按照接收COT信息的顺序确定。可选的,上述其中一个可用COT信息为满足预设第一条件的可用COT信息。上述第一条件可以是COT信息指示的信道接入优先级最高,也可以是COT信息指示的信道接入优先级最低,还可以是COT信息中指示的资源数量最多。可选的,第一条件为COT信息指示范围的剩余时长最长;剩余时长为COT信息对应的结束时隙与当前时隙之间的时长。The method for the physical layer of the user equipment to select one COT information from multiple COT information can refer to the above embodiment. When the user equipment selects one of the available COT information among multiple COT information, it can select it randomly or according to the order in which the COT information is received. Optionally, one of the above available COT information is the available COT information that satisfies the preset first condition. The above first condition may be that the channel access priority indicated by the COT information is the highest, or that the channel access priority indicated by the COT information is the lowest, or that the number of resources indicated in the COT information is the largest. Optionally, the first condition is that the remaining duration of the range indicated by the COT information is the longest; the remaining duration is the duration between the end time slot corresponding to the COT information and the current time slot.
S304、将候选资源集合中其中一个可用COT信息指示的COT范围内的候选资源组成第一资源集合。S304. Compose a first resource set from one of the candidate resources in the candidate resource set that is within the COT range indicated by the available COT information.
用户设备的物理层在选择一个可用COT信息之后,可以将候选资源集合中各可用COT信息指示的COT范围内的候选资源组成第一资源集合。上述物理层基于一个COT信息对候选资源集合进行筛选的方式,与高层接收到一个COT信息对候选资源集合进行筛选的方式类似,可以参见图7对应的实施例,在此不做赘述。After selecting one available COT information, the physical layer of the user equipment may form a first resource set from candidate resources within the COT range indicated by each available COT information in the candidate resource set. The above-mentioned method of the physical layer screening the candidate resource set based on a piece of COT information is similar to the way that the upper layer receives a piece of COT information to screen the candidate resource set. Please refer to the corresponding embodiment in Figure 7 and will not be described in detail here.
在另一种实现方式中,用户设备的物理层还可以根据收集到的多个可用COT信息对候选资源集合进行筛选,其确定第一资源集合的方式与上述实施例中高层根据物理层上报的多个COT信息对候选资源集合进行筛选的方式类似,可以参加图6对应的实施例,在此不做赘述。In another implementation, the physical layer of the user equipment can also filter the candidate resource set based on the collected multiple available COT information. The method of determining the first resource set is the same as in the above embodiment based on the high-level information reported by the physical layer. The method of screening the candidate resource set by multiple COT information is similar and can be referred to the corresponding embodiment in Figure 6, which will not be described in detail here.
上述传输资源的选择方法,用户设备通过物理层对候选资源集合进行筛选,获得第一资源集合,使得用户设备可以从其他用户设备共享的资源中随机选择传输资源,提高LBT成功率。In the above transmission resource selection method, the user equipment filters the candidate resource set through the physical layer to obtain the first resource set, so that the user equipment can randomly select transmission resources from resources shared by other user equipment, thereby improving the LBT success rate.
用户设备的物理层获得第一资源集合之后,是否将第一资源集合上报至高层取决于用户设备实现。用户设备的物理层向高层上报的资源集合可以有不同方式。After the physical layer of the user equipment obtains the first resource set, whether to report the first resource set to the higher layer depends on the user equipment implementation. The resource set reported by the physical layer of the user equipment to the higher layer can be in different ways.
可选的,物理层上报至高层的资源集合可以是候选资源集合,高层可以在候选资源集合中随机选择传输资源。Optionally, the resource set reported by the physical layer to the higher layer can be a candidate resource set, and the higher layer can randomly select transmission resources from the candidate resource set.
可选的,物理层上报至高层的资源集合包括第一资源集合和候选资源集合。高层可以在第一资源集合中随机选择传输资源,或者在候选资源集合中随机选择传输资源,对于如何选择取决于用户设备实现。 可选的,用户设备的高层可以根据候选资源集合和第一资源集合中的资源数量进行选择。用户设备的高层可以在第一资源集合的资源数量与候选资源集合数量的比值大于或等于第一阈值时,从第一资源集合中随机选择传输资源;其中,第一阈值小于1。在第一资源集合的资源数量与候选资源集合数量的比值小于第一阈值时,从候选资源集合中随机选择传输资源。其中,上述第一阈值为网络侧配置的参数,或,第一阈值为预配置参数。Optionally, the resource set reported by the physical layer to the higher layer includes a first resource set and a candidate resource set. The higher layer may randomly select transmission resources from the first resource set, or randomly select transmission resources from the candidate resource set. How to select depends on the user equipment implementation. Optionally, a higher layer of the user equipment may make a selection based on the candidate resource set and the number of resources in the first resource set. The higher layer of the user equipment may randomly select transmission resources from the first resource set when the ratio of the number of resources in the first resource set to the number of candidate resource sets is greater than or equal to the first threshold; wherein the first threshold is less than 1. When the ratio of the number of resources in the first resource set to the number of candidate resource sets is less than the first threshold, a transmission resource is randomly selected from the candidate resource set. Wherein, the above-mentioned first threshold is a parameter configured on the network side, or the first threshold is a pre-configured parameter.
可选的,物理层上报至高层的资源集合为第一资源集合,高层可以在第一资源集合中随机选择传输资源。Optionally, the resource set reported by the physical layer to the higher layer is the first resource set, and the higher layer can randomly select transmission resources from the first resource set.
在一个实施例中,提供一种传输资源的选择方法,如图9所示,包括:In one embodiment, a transmission resource selection method is provided, as shown in Figure 9, including:
