技术领域Technical field
本申请涉及移动通信技术领域,例如涉及一种第五代移动通信***(the 5th Generation mobile communication system,5G)通信方法、***、设备及存储介质。The present application relates to the field of mobile communication technology, for example, to a fifth-generation mobile communication system (the 5th Generation mobile communication system, 5G) communication method, system, device, and storage medium.
背景技术Background technique
随着网络技术的发展,5G***应运而生,5G***可配置最小带宽为5MHz,最大带宽为400MHz的新无线(New Radio,NR)小区;基于用户设备的性能的考虑,相关技术中并非每个用户设备都支持和使用400MHZ的带宽,因此,为了提高调度的灵活性,第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)协议引入了带宽部分(Bandwidth Part,BWP),网络侧把整个5G小区所支持的带宽划分为多个BWP,通过BWP为用户设备提供网络服务。With the development of network technology, 5G systems came into being. 5G systems can be configured with new radio (NR) cells with a minimum bandwidth of 5 MHz and a maximum bandwidth of 400 MHz. Based on the performance of user equipment, not every Each user equipment supports and uses the bandwidth of 400MHZ. Therefore, in order to increase the flexibility of scheduling, the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) protocol introduces the bandwidth part (Bandwidth Part, BWP). The bandwidth supported by the 5G cell is divided into multiple BWPs to provide network services to user equipment through BWP.
相关技术中,一旦NR小区配置成功,用户设备接入网络后,BWP的个数、子载波间隔(subcarrier spacing)、循环前缀(cyclic prefix)就已经固定,当NR小区配置了多个BWP时,基于同一个时刻仅能激活一个BWP,因此无论何时用户设备均无法体验极限峰值速率;而若仅为一个NR小区配置一个BWP,对于不同业务、不同场景无法满足用户设备的需求。In the related art, once the NR cell is successfully configured and the user equipment is connected to the network, the number of BWP, subcarrier spacing, and cyclic prefix are fixed. When multiple BWPs are configured in the NR cell, Because only one BWP can be activated at the same time, user equipment cannot experience the limit peak rate at any time; and if only one BWP is configured for one NR cell, it cannot meet the needs of user equipment for different services and different scenarios.
综上所述,相关技术中缺少一种可按照用户设备的需求灵活调度分配带宽的5G通信方法及***。In summary, the related art lacks a 5G communication method and system that can flexibly schedule and allocate bandwidth according to the needs of user equipment.

具体实施方式detailed description
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行描述,本文所描述的实施例是本申请一部分实施例,而不是全部的实施例。The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. The embodiments described herein are a part of the embodiments of the present application, but not all the embodiments.
图1为本申请实施例提供的一种5G通信方法的流程图,图2为本申请实施例提供的另一种5G通信方法的流程图。如图1和图2所示,本申请实施例提供的方法应用于5G通信***中的网络侧,该方法可包括步骤S102-步骤S106。FIG. 1 is a flowchart of a 5G communication method provided by an embodiment of the application, and FIG. 2 is a flowchart of another 5G communication method provided by an embodiment of the application. As shown in FIGS. 1 and 2, the method provided by the embodiment of the present application is applied to the network side in a 5G communication system, and the method may include steps S102-S106.
步骤S102、获取用户设备的带宽需求以及网络***的DCI格式文件。Step S102: Obtain the bandwidth requirements of the user equipment and the DCI format file of the network system.
在本申请实施例中,用户设备的不同网络需求对应不同的带宽需求,如,观看在线视频需要的带宽需求较通过即时通讯软件发送文字信息给其他用户设备的带宽需求要高。在本申请实施例中,在获取到用户设备的带宽需求的同时或者之后,继续获取网络***的DCI格式文件,根据网络***中的DCI格式文件,为用户设备分配相应的BWP。In the embodiment of the present application, different network requirements of user equipment correspond to different bandwidth requirements. For example, the bandwidth requirement for watching online videos is higher than the bandwidth requirement for sending text messages to other user equipment through instant messaging software. In the embodiment of the present application, at the same time or after acquiring the bandwidth requirement of the user equipment, the DCI format file of the network system is continuously obtained, and the corresponding BWP is allocated to the user equipment according to the DCI format file in the network system.
步骤S104、根据所述带宽需求以及所述DCI格式文件,确定为所述用户设备分配的BWP。Step S104: Determine the BWP allocated to the user equipment according to the bandwidth requirement and the DCI format file.
在本申请实施例中,确定为用户设备分配的BWP,是基于5G通信***中的DCI格式文件,而并未引入其他的格式文件,有效保障了5G通信***的复杂度,In the embodiment of the present application, it is determined that the BWP allocated to the user equipment is based on the DCI format file in the 5G communication system, and no other format file is introduced, which effectively guarantees the complexity of the 5G communication system.
步骤S106、将所述BWP分配给用户设备。Step S106: Assign the BWP to the user equipment.
在本申请实施例中,为用户设备分配的BWP是基于用户设备的需求而进行分配,可有效满足根据用户需求灵活分配BWP的目的。In the embodiment of the present application, the BWP allocated to the user equipment is allocated based on the needs of the user equipment, which can effectively meet the purpose of flexibly allocating the BWP according to user needs.
在本申请一个实施例中,在步骤S102之后,还包括:调用DCI格式文件中的指示位;所述步骤S104,包括:根据所述带宽需求以及所述DCI格式文件中的指示位确定所述带宽需求所对应的BWP。In an embodiment of the present application, after step S102, the method further includes: calling an indicator bit in the DCI format file; and step S104 includes: determining the indicator bit according to the bandwidth requirement and the indicator bit in the DCI format file BWP corresponding to bandwidth requirements.
在本申请实施例中,通过DCI格式文件的指示位确定所述带宽需求所对应的BWP,无需添加协议文件,同时保障为用户设备灵活分配BWP。In the embodiment of the present application, the BWP corresponding to the bandwidth requirement is determined through the indication bits of the DCI format file, without adding a protocol file, and at the same time ensuring flexible allocation of BWP for user equipment.
在本申请实施例中,所述方法还包括:判断所述带宽需求所对应的BWP的利用率是否达到预设负荷;响应于所述带宽需求所对应的BWP的利用率达到预设负荷的判断结果,扩大所述带宽需求对应的BWP的频率范围。In the embodiment of the present application, the method further includes: determining whether the utilization rate of the BWP corresponding to the bandwidth requirement reaches a preset load; and determining whether the utilization rate of the BWP corresponding to the bandwidth requirement reaches the preset load As a result, the frequency range of the BWP corresponding to the bandwidth requirement is expanded.
在本申请实施例中,当根据DCI格式文件中的指示位确定的BWP的利用率已经达到预设负荷时,则扩大该确定的BWP,以满足用户设备的带宽需求,有效缓解了相关技术中不能灵活调节BWP的带宽范围,从而造成网络阻塞或拥堵的技术问题。In the embodiment of the present application, when the utilization rate of the BWP determined according to the indicator bit in the DCI format file has reached the preset load, the determined BWP is expanded to meet the bandwidth requirements of the user equipment, which effectively alleviates the related technology. The BWP bandwidth range cannot be flexibly adjusted, thereby causing technical problems of network congestion or congestion.
如下,列举一个例子进行阐述:The following is an example to illustrate:
网络侧根据一时刻T1,每个BWP的在网用户数和业务量,用表格统计该BWP上带宽利用率,并记录闲置、未使用的带宽;当下一时刻T2,若一个BWP带宽利用率超负荷或接近超负荷,网络侧可通过DCI动态临时扩大该BWP,根据维护和记录每个BWP的表格,动态调度有闲置带宽(bandwidth)的BWP,以为这些用户提供更宽的调度带宽。The network side uses a table to count the bandwidth utilization on the BWP based on the number of users and traffic on each BWP at a time T1, and records the idle and unused bandwidth; when the next time T2, if a BWP bandwidth utilization exceeds When the load is close to overload, the network side can dynamically expand the BWP temporarily through DCI. According to the table of maintaining and recording each BWP, the BWP with idle bandwidth (bandwidth) is dynamically scheduled to provide these users with a wider scheduling bandwidth.
在本申请实施例中,所述方法还包括:在确定的所有BWP中每一个BWP不满足所述用户设备的带宽需求的情况下,根据所述用户设备的带宽需求的频率范围为所述用户设备分配BWP。In the embodiment of the present application, the method further includes: in a case where each of the determined BWPs does not meet the bandwidth requirements of the user equipment, a frequency range according to the bandwidth requirements of the user equipment is the user The device assigns BWP.
在本申请实施例中,若通过网络***的DCI格式文件的指示位确定当前所有BWP中每一个BWP不满足用户设备的带宽需求,则根据用户设备的带宽频率的需求范围,为用户设备分配BWP。In the embodiment of the present application, if it is determined by the indicator bit of the DCI format file of the network system that each of the current BWPs does not meet the bandwidth requirements of the user equipment, the user equipment is allocated a BWP according to the bandwidth frequency range of the user equipment .
如:一个用户设备因一种需求在一时刻的需求带宽为400MHZ的全带宽,则网络侧在接收到该用户设备的带宽需求后,通过DCI格式文件的指示位,未确定出满足用户设备的带宽需求的BWP,则网络侧根据用户设备的频率的需求灵活调整,为用户设备分配400MHZ的BWP。For example, a user equipment needs a full bandwidth of 400MHZ at a time due to a demand. After receiving the bandwidth demand of the user equipment, the network side does not determine the content of the user equipment through the indication bit of the DCI format file. For the BWP with bandwidth requirements, the network side flexibly adjusts according to the frequency requirements of the user equipment, and allocates 400MHZ BWP to the user equipment.
在本申请实施例中,指示位设置在扩展后的DCI格式指示位中,或者设置在DCI格式文件的新增加的字段中。In the embodiment of the present application, the indication bit is set in the expanded DCI format indication bit, or in a newly added field of the DCI format file.
在5G通信***中,存在DCI格式文件,且在DCI格式文件中设置有格式指示位,而本申请中的指示位可以是设置在格式指示位中,只需要对格式指示位进行扩展;除此之外,也可在DCI格式文件中新增字段,以将本申请实施例中的指示位设在新增字段中,以与格式指示位相对独立设置。In the 5G communication system, there is a DCI format file, and the format indicator bit is set in the DCI format file, and the indicator bit in this application may be set in the format indicator bit, and only the format indicator bit needs to be extended; except this In addition, a field may be added in the DCI format file to set the indicator bit in the embodiment of the present application in the newly added field to be set independently from the format indicator bit.
在本申请实施例中,用户设备在接收到网络侧分配的BWP之后,用户设备根据相关技术中的搜索空间解析物理下行控制信道(Physical Downlink Control Channel,PDCCH)获取DCI格式文件,得知网络侧通过该DCI中新增字段或扩展DCI中已有字段自适应调整BWP的指示,在指定的位置上发送或者接收相应的物理上行共享信道(Physical Uplink Shared Channel,PUSCH)或者物理下行共享信道(Physical Downlink Shared Channel,PDSCH)。In the embodiment of the present application, after receiving the BWP allocated by the network side, the user equipment parses the physical downlink control channel (Physical Downlink Control Channel, PDCCH) according to the search space in the related art to obtain the DCI format file, and learns that the network side Send or receive the corresponding physical uplink shared channel (Physical Uplink Shared Channel (PUSCH) or physical downlink shared channel (Physical Downlink Shared Channel, PDSCH).
如下,列举两个实施例进行阐述:As follows, two examples are listed for explanation:

LSBs provide resource allocation,
Figure PCTCN2019113237-appb-000006
It is the uplink extended RB number.
在用户设备接入网络后,不同的带宽需求会处于不同的激活态BWP(active BWP);网络侧根据每个BWP的在网用户数和业务量周期性地维护一个数据表格,统计每个BWP的bandwidth利用率,可实时获知空闲带宽的大小。After the user equipment is connected to the network, different bandwidth requirements will be in different active BWP (active BWP); the network side periodically maintains a data table based on the number of users and traffic of each BWP on the network to count each BWP The bandwidth utilization rate can be real-time informed of the size of the idle bandwidth.
若在一时刻,网络侧根据维护的数据表格,发现一个BWP的带宽利用率达到预设值,同时其他BWP存在空闲带宽,那么网络侧在下一个调度周期通过 DCI的指示位指示临时动态扩大调度的带宽,用
Figure PCTCN2019113237-appb-000007
LSBs指示扩大的带宽的资源分配。
If at a moment, the network side finds that the bandwidth utilization of a BWP reaches a preset value according to the maintained data table, and other BWPs have idle bandwidth, then the network side indicates the temporary dynamic expansion of the scheduling through the DCI indicator bit in the next scheduling cycle. Bandwidth, use
Figure PCTCN2019113237-appb-000007
LSBs indicate resource allocation for expanded bandwidth.
用户设备配置参数,解析PDCCH获取到DCI格式文件后,得知为该用户设备扩大的带宽所在起始位置和RB数,相应的发送或者接收PUSCH或者PDSCH,以避免一个BWP超负荷使用时引起的延时调度或不调度问题,提升网络侧资源利用率和频谱效率的同时,也提升了用户的体验度。User equipment configuration parameters, after parsing the PDCCH to obtain the DCI format file, know the starting position and RB number of the expanded bandwidth for the user equipment, and send or receive the PUSCH or PDSCH accordingly to avoid a BWP overload usage caused The problem of delayed scheduling or non-scheduling improves the network-side resource utilization and spectrum efficiency, and also improves the user experience.
实施例二Example 2
网络侧配置一个NR小区有4个BWP,周期性的统计每个BWP的带宽使用状态;在统计周期T1,网络侧根据每个BWP的在网用户设备及在网用户设备的需求带宽,维护一个数据表格,统计每个BWP的带宽利用率,获知该周期空闲带宽的大小,如图3所示。The network side configures an NR cell with 4 BWPs, and periodically counts the bandwidth usage status of each BWP; during the statistical period T1, the network side maintains one according to the demanded bandwidth of each BWP's network user equipment and network user equipment The data table counts the bandwidth utilization of each BWP and learns the size of idle bandwidth in the period, as shown in Figure 3.
随着一些用户或一个区域的业务量变大,在统计周期T2时刻,网络侧根据维护的数据表格发现BWP2的带宽使用情况已达到预访问量,而BWP3依然存在大量未使用的带宽,那么网络侧通过DCI的一个字段,告知BWP2的在网用户使用BWP3的部分带宽,临时扩大调度以满足用户的业务量,如图4所示,以避免BWP2的在网用户的延时调度或不调度现象。As the traffic of some users or a region becomes larger, at the time of statistical period T2, the network side finds that the bandwidth usage of BWP2 has reached the pre-visited amount according to the maintained data table, and there is still a large amount of unused bandwidth in BWP3. Through a field of DCI, inform the users of BWP2 to use part of the bandwidth of BWP3, temporarily expand the scheduling to meet the user's traffic, as shown in Figure 4, to avoid the delay or non-scheduling of BWP2's users on the network.
本申请实施例公开的5G通信方法,可以根据用户设备的需求带宽灵活调整BWP,并为用户设备分配BWP,本方案可根据用户设备的带宽需求动态灵活调整或分配BWP,可有效克服由于NR小区的用户设备集中访问一个BWP从而造成网络拥堵的现象,同时可有效避免固定划分的BWP的每一个BWP的带宽需求不满足某用户设备的带宽需求,导致该用户设备无法体验超过任何一个BWP的带宽的极限网速的技术问题。The 5G communication method disclosed in the embodiment of the present application can flexibly adjust the BWP according to the bandwidth requirements of the user equipment and allocate BWP to the user equipment. This solution can dynamically adjust or allocate the BWP dynamically according to the bandwidth requirements of the user equipment, which can effectively overcome the NR cell Of user equipment accesses a BWP centrally, causing network congestion, and at the same time, it can effectively avoid that the bandwidth requirements of each BWP of a fixed divided BWP do not meet the bandwidth requirements of a certain user equipment, resulting in that the user equipment cannot experience more bandwidth than any one BWP The technical problem of the extreme network speed.
参见图5所示,本申请实施例公开一种5G通信方法,应用于网络访问量超过预设访问量的时间段,所述方法包括步骤S202-步骤S206。As shown in FIG. 5, an embodiment of the present application discloses a 5G communication method, which is applied to a time period in which network access exceeds a preset access, and the method includes steps S202-S206.
步骤S202、获取当前的时间段。Step S202: Obtain the current time period.
在本申请实施例中,当前的时间段为用户访问当前BWP的时间段。In the embodiment of the present application, the current time period is the time period during which the user accesses the current BWP.
步骤S204、在当前的时间段为网络访问量超过预设访问量的时间段的情况下,按照用户设备的优先级,为所述用户设备重新分配BWP。Step S204: When the current time period is a time period in which the network access volume exceeds the preset access volume, redistribute the BWP for the user equipment according to the priority of the user equipment.
在本申请实施例中,在网络***中预设有时间段的划分,该划分是根据历史数据进行归类划分,如经过一段时间的统计,发现一区域在13:00-14:00时间段内对一个BWP的访问量超过预设访问量,则当获取到用户设备访问BWP的时间段落在13:00-14:00时间段内时,则获取到的时间段为网络访问量超过预设访问量的时间段。In the embodiment of the present application, a division of time period is preset in the network system. The division is based on historical data. For example, after a period of statistics, an area is found in the time period of 13: 00-14: 00 If the number of internal visits to a BWP exceeds the preset number of visits, when the time period for obtaining the BWP accessed by the user equipment is within the time period of 13: 00-14: 00, the time period obtained is that the amount of network visits exceeds the preset amount The time period of traffic.
若获取到的当前的时间段为访问量超过预设访问量的时间段,则网络侧按照用户设备的优先级,为用户设备动态分配多个BWP。If the acquired current time period is a time period where the amount of access exceeds the preset amount of access, the network side dynamically allocates multiple BWPs to the user equipment according to the priority of the user equipment.
步骤S206、为用户设备从为用户设备分配的多个BWP中选择并激活BWP。Step S206: The user equipment selects and activates the BWP from the multiple BWPs allocated to the user equipment.

Generally, there is more than one dedicated BWP allocated to the user equipment by the network side, such as It can be four, and when selecting and activating a BWP from multiple BWPs allocated to the user equipment, select a dedicated BWP that is greater than the bandwidth demand of the user equipment and is closest to the bandwidth demand of the user equipment, and activate the dedicated BWP.
在本申请实施例中,在步骤S204中,包括:In the embodiment of the present application, in step S204, it includes:
1)根据用户设备的需求带宽划分每个BWP的带宽频率。1) Divide the bandwidth frequency of each BWP according to the required bandwidth of the user equipment.
在本申请实施例中,可将小区带宽BW fullband等分为N个子带,将所有子带按频域顺序编号1,2,...,N,每个子带带宽为BW subband=BW fullband/N,每个子带上都需要维护一个名为配置数的参数:nrofConfig n,n=1,...,N,每个配置数用于统计对应的子带被配置为BWP的次数。nrofConfig n初始值为0,每当一个子带被配置为一个用户设备(User Equipment,UE)的BWP时,这个子带的配置数就会加一;当基站取消UE原有BWP配置时,所有相关子带的配置数减一。 In the embodiment of the present application, the cell bandwidth BW fullband can be equally divided into N subbands, and all the subbands are numbered in the frequency domain order 1,2, ..., N, and the bandwidth of each subband is BW subband = BW fullband / N, each subband needs to maintain a parameter named configuration number: nrofConfig n , n = 1, ..., N, each configuration number is used to count the number of times the corresponding subband is configured as BWP.
