在图1所示通信系统中,以终端设备103与终端设备104进行侧行链路通信为例,当的终端设备103要向终端设备104发送数据时,终端设备103可以先向终端设备104发送侧行链路控制信息,该侧行链路控制信息中携带数据的相关信息(例如:时频资源等)。终端设备104不知道终端设备103是否发送侧行链路控制信息,也不知道终端设备103在哪个资源上发送侧行链路控制信息,因此,终端设备104在有可能发送侧行链路控制信息的地方都需要盲检终端设备103发送的侧行链路控制信息,若该侧行链路控制信息正确接收,并且侧行链路控制信息包括的标识与终端设备104的标识匹配,终端设备104可以根据该侧行链路控制信息中携带的数据的相关信息接收数据。

在具体的实现中,作为一种实施例,处理器201可以包括一个或多个CPU,例如图2中所示的CPU0和CPU1。
在具体实现中,作为一种实施例,通信装置可以包括多个处理器,例如图2中所示的处理器201和处理器205。这些处理器中的每一个可以是一个单核处理器
(single-CPU),也可以是一个多核处理器(multi-CPU)。这里的处理器可以指一个或多个通信设备、电路、和/或用于处理数据(例如计算机程序指令)的处理核。
存储器202可以是只读存储器(read-only memory,ROM)或可存储静态信息和指令的其他类型的静态存储通信设备,随机存取存储器(random access memory,RAM)或者可存储信息和指令的其他类型的动态存储通信设备,也可以是电可擦可编程只读存储器(electrically erasable programmable read-only memory,EEPROM)、只读光盘(compact disc read-only memory,CD-ROM)或其他光盘存储、光碟存储(包括压缩光碟、激光碟、光碟、数字通用光碟、蓝光光碟等)、磁盘存储介质或者其他磁存储通信设备、或者能够用于携带或存储具有指令或数据结构形式的期望的程序代码并能够由计算机存取的任何其他介质,但不限于此。存储器202可以独立存在,通过通信总线204与处理器201相连接。也可以和处理器201集成在一起。

在本申请实施例中,上述存储器202可以存储有软件程序或指令。当通信装置200上电后,处理器201可以读取并执行存储器202中存储的软件程序或指令,以使得通信装置200可以执行下述图3所示的通信方法,具体实现方式可以参考下述方法实施例,此处不再赘述。

在有网络覆盖的场景下,终端设备均位于网络设备覆盖范围内,网络设备通过下行信令动态为终端设备配置资源,以使得终端设备利用网络设备配置的资源在侧行链路上进行直接通信。在部分网络覆盖场景下,部分终端设备位于网络设备覆盖范围内,部分终端设备位于网络设备覆盖范围外,网络设备通过下行动态信令为位于网络覆盖范围内的终端设备配置资源,位于网络覆盖范围内的终端设备接收并转发网络设备配置的资源给网络覆盖范围外的终端设备,以使得网络覆盖范围内的终端设备和网络覆盖范围外的终端设备利用网络设备配置的资源在侧行链路上进行直接通信。在无网络覆盖场景下,终端设备均位于网络设备覆盖范围外,网络设备无法通过下行动态信令为位于网络覆盖范围外的终端设备配置资源,因此终端设备利用预定义资源在侧行链路上进行直接通信。
在D2D场景以及V2X场景中,为终端设备进行资源分配的方式主要有两种,分别为集中控制式的资源分配方法和基于竞争的分布式资源分配方法。在集中控制式的资源分配方法中,终端设备传输业务所需的资源由网络设备,如基站或中继站等分配,这种资源分配方式主要针对于有网络覆盖的场景。在基于竞争的分布式资源分配方法中,终端设备传输业务所需的资源需要通过竞争从资源池中获取,在有网络覆盖的场景下,资源池为网络设备分配给终端设备的资源,在无网络覆盖的场景下,资源池为预定义资源,因此这种资源分配方式可以用于有网络覆盖的场景以及无网络覆盖的场景。需要说明的是,V2X场景下的基于竞争的分布式资源分配方法中,引入了监听机制。终端设备可以监听其他终端设备发送的侧行控制信息,从而排除网络设备分配的资源中或者预定义资源中分配给其他终端设备的资源,在剩余的资源中选择自身所需要的资源。
在无网络覆盖的场景下,网络设备无法为终端设备分配资源,因此在基于竞争的资源分配方式中,引入基于终端调度的资源分配方式:先从所有终端设备中确定一个终端设备为调度终端,其他终端为被调度终端,然后由调度终端利用预定义资源为被调度终端分配资源。需要说明的是,具有不同能力的终端的类型不同,在现有的基于终端调度的资源分配方式中,虽然调度终端与被调度终端的作用有所不同,但两者的能力相同且未发生变化,同时终端类型也未发生变化。
为了解决基于终端调度的资源分配方式中的终端类型设计的问题,本申请实施例对终端类型进行设计,定义了两种终端能力,分别为第一能力和第二能力。在一种可能的实现方式中,第一能力包括接收调度终端分配的资源,第二能力包括作为调度终端分配资源。因此,调度终端至少具备第二能力,被调度终端至少具备第一能力。在本申请实 施例中,通过能力信息表示终端所具备的能力。
示例性的,能力信息的一种实现方式如表1所示。
表1
field state description

表1中,能力信息以2bit字符表示,能力信息的不同取值表示终端具备不同的能力。例如:当能力信息的取值为00时,表示终端不支持基于终端调度的资源分配方式。当能力信息的取值为01时,表示终端支持接收调度终端分配的资源,也即终端具有第一能力。当能力信息的取值为10时,表示终端能够作为调度终端分配资源,也即终端具有第二能力。
示例性的,以发送能力信息的终端为发送方终端,接收发送方终端发送的能力信息的终端为接收方终端为例,若发送方终端发送的能力信息的取值为00,则接收方终端确定发送方终端为不支持基于终端调度的资源分配方式的终端;若发送方终端发送的能力信息的取值为01,则接收方终端确定发送方终端具有第二能力;若发送方终端发送的能力信息的取值为10,则接收方终端确定发送方终端具有第一能力;若发送方终端发送的能力信息的取值为11,则该能力信息无效。
需要说明的是,对于组播通信,支持接收调度终端分配的资源的终端可以是普通的组员终端,支持分配资源的调度终端可以是组头终端。
在另一种实现方式中,为了解决基于终端调度的资源分配方式中的终端类型设计的问题,本申请实施例对终端类型进行设计,定义了两种终端能力,分别为第一能力和第二能力。第一能力包括接收调度终端分配的资源/资源池,第二能力包括作为调度终端分配资源/资源池,除此之外,第二能力还包括以下至少一种:支持比例公平调度算法、载波聚合能力、并行处理能力、由调度终端分配资源的被调度终端的数量、支持的最大进程数、支持的最大天线数、缓存空间和发射功率。其中,载波聚合能力表示该终端可以在多个载波上工作,并行处理能力表示该终端可以同时处理的进程的数量为多个,支持的最大进程数表示终端能够处理的总进程数且该总进程数大于被调度终端能够处理的总进程数,支持的最大天线数表示终端的总天线端口数,且该总天线端口数大于被调度终端的总天线端口数,缓存空间用于表示终端的缓存空间大小,且该缓存空间大小大于被调度终端的缓存空间大小,发射功率表示终端允许达到的最大发射功率,且该最大发射功率大于被调度终端的最大发射功率。因此,调度终端至少具备第二能力,被调度终端至少具备第一能力。在本申请实施例中,通过能力信息表示终端所具备的能力。示例性的,进程指的是混合自动重传请求(hybrid automatic repeat request,HARQ)。

表2中,能力信息以4bit字符表示,能力信息的不同取值表示终端具备不同的能力。例如:当能力信息的取值为0000时,表示终端不支持基于终端调度的资源分配信息方式。当能力信息的取值为0001时,表示终端支持接收调度终端分配的资源,即终端具有第一能力。当能力信息的取值为0010时,表示终端支持接收调度终端分配的资源池,即终端具有第一能力。当能力信息的取值为0011时,表示终端能够作为调度终端分配资源,即终端具有第二能力。当能力信息为0100时,表示终端能够作为调度终端分配资源池,即终端具有第二能力。当能力信息为0101时,表示终端支持比例公平调度算法。当能力信息的取值为0110时,表示终端支持最大进程数16。当能力信息的取值为0111时,表示终端支持的天线数4。当能力信息的取值为1000时,表示终端支持SL载波聚合。当能力信息为1001时,表示终端支持并行处理能力。当能力信息的取值为1010时,表示终端支持较大缓存。当能力信息的取值为1011时,表示终端支持最大发射功率31dB。当能力信息的取值为1100时,表示终端支持最大发射功率46dB。
示例性的,以发送能力信息的终端为发送方终端,接收发送方终端发送的能力信息的终端为接收方终端,支持最大进程数为16,支持的天线数为4,最大发射功率为31dB和46dB为例,若发送方终端发送的能力信息的取值为0000,则接收方终端确定发送方终端为不支持基于终端调度的资源分配方式的终端;若发送方终端发送的能力信息的取值为0001或0010,则接收方终端确定发送方终端为支持接收调度终端分配的资源或资源池的终端;若发送方终端发送的能力信息的取值为0011或0100,则接收方终端确定发送方终端为支持作为调度终端分配资源的终端;若发送方终端发送的能力信息的取值为0101,则接收方终端确定发送方终端为支持公平调度算法的终端;若发送方终端发送的能力信息的取值为0110,则接收方终端确定发送方终端为支持最大进程数16的终端;若发送方终端发送的能力信息的取值为0111,则接收方终端确定发送方终端为支持天线数4的终端;若发送方终端发送的能力信息的取值为1000,则接收方终端确定发送方终端为支持SL载波聚合的终端;若发送方终端发送的能力信息的取值为1001,则接收方 终端确定发送方终端为支持并行处理能力的终端;若发送方终端发送的能力信息的取值为1010,则接收方终端确定发送方终端为支持较大缓存的终端;若发送方终端发送的能力信息的取值为1011或1100,则接收方终端确定发送方终端为支持最大发射功率31dB或46dB的终端。
示例性的,类似于最大发射功率,若有一调度终端所支持的最大进程数为8,则可以确定该终端发送的能力信息的取值为1101,来表示终端支持最大进程数8。若有一调度终端所支持的天线数为8,则可以确定该终端发送的能力信息的取值为1110,来表示终端支持的天线数8。
需要说明的是,载波聚合能力包括聚合载波的数量和/或波段。
示例性的,以1000表示终端支持载波聚合。若有一调度终端支持的载波有a1,a2,a3,则可以以6bit的字符表示。例如100000表示终端支持载波聚合且载波可以为a1,例如100001表示终端支持载波聚合且载波可以为a2,例如100010表示终端支持载波聚合且载波可以为a3。或者调度终端所支持的载波聚合的载波数量为2、3、4,也可以以6bit的字符表示。例如100000、100001或100010分别表示调度终端支持载波聚合且支持的载波数量为2、3或4。具体的如何表示第二能力可以根据实际情况确定,并不局限于上述提到的表示方式。
需要说明的是,比例公平调度算法的基本思想是在选择用户时考虑瞬时速率和长期平均速率的比值,同时利用权重值对不同用户进行调整,达到在尽量满足信道质量较好的终端的高速数据业务需求的同时,兼顾信道质量状况不好的终端的使用体验的目的。比例公平调度算法为小区内每个用户都分配了一个优先级,在任意时刻系统调度优先级最大的用户。另外,为了满足单用户峰值速率和系统容量提升的要求,一种最直接的办法就是增加系统传输带宽。因此长期演进(long term evolution-advanced,LTE-A)系统引入一项增加传输带宽的技术,也就是载波聚合(carrier aggregation,CA),载波聚合是LTE-A中的关键技术。CA技术可以将2-5个LTE成员载波(component carrier,CC)聚合在一起,实现最大100MHz的传输带宽,有效提高上下行传输速率,终端可以根据自己的能力大小决定最多可以同时利用几个载波进行上下行传输。
示例性的,比例公平调度算法的数学表达式可以参考式
Figure PCTCN2020109896-appb-000001
其中k是被调度用户的优先级,Ri(t)为用户i在t时刻请求的速率,Ti(t)为用户i在t时刻的累积平均速率。在调度完成后,对用户的优先级因子进行更新。若小区中有多个用户,当系统对某个信道质量较好的用户连续进行了调度时,Ti(t)将会逐渐增大,使得优先级逐渐变小,从而系统会调度其他优先级较高的用户。若某个用户的信道质量较差,长期得不到系统的调度,那么它的平均吞吐量Ti(t)会降低,这样的话优先级将会增大,使用户获得被调度的机会。因此比例公平算法综合考虑了公平性和系统性能两方面的因素,是一种性能较优的算法。
结合上述基于终端调度的资源分配方式的终端类型的设计,本申请实施例中的通信系统包括至少一个第一终端以及至少一个第二终端,第一终端具备第一能力和/或第二能力,第二终端具备第一能力和/或第二能力。下面以第一终端具备第一能力,第二终端具备第二能力为例,结合图1和图2对本申请实施例提供的通信方法进行具体阐述。图3中的(a)为本申请提供的通信方法的流程示意图,可以应用于图1中的任一终端,如图1的(c)中的终端设备102-终端设备108,或者图2所示的通信装置200,完成与另 一终端设备,如图1的(c)中的终端设备102-终端设备108,在侧行链路上的直接通信。如图3中的(a)所示,该通信方法包括如下步骤:
S301、第二终端发送其能力信息给第一终端,相应地,第一终端接收第二终端的能力信息。
其中,第二终端的能力信息指示第二终端具有第二能力,第二能力包括作为调度终端为与其对应的被调度终端分配资源。可选的,第二能力包括作为调度终端分配资源/资源池。在本实施例中,第一终端具有第一能力,第二终端具备第二能力,因此,第一终端为被调度终端,第二终端为调度终端。
在第一终端与第二终端需要进行通信时,先由第二终端发送第二终端的能力信息给第一终端,然后第一终端在接收到第二终端的能力信息后,根据第二终端的能力信息的取值,确定第二终端为分配资源/资源池的调度终端。
可选的,第二终端的能力信息可以通过以下至少一种信令承载:RRC信令、MAC信令、广播消息、系统消息、物理层信令。物理层信令可以是下行链路控制信息DCI或侧行链路控制信息SCI。其中,RRC信令可以是RRC信息单元(information element,IE),MAC信令可以是MAC控制单元(control element,CE),广播消息可以是主信息块(master information block,MIB),系统消息可以是系统信息块(system information block,SIB),物理层信令可以是下行控制信息(downlink control information,DCI)、或者侧行链路控制信息(sidelink control information,SCI)。其中,RRC信令、MAC信令、系统消息在物理下行共享信道(physical downlink shared channel,PDSCH)承载,广播消息在物理广播信道(physical broadcast channel,PBCH)承载,物理层信令在物理下行控制信道(physical downlink control channel,PDCCH)或物理侧行控制信道(physical sidelink control channel,PSCCH)承载。关于以上至少一种信令的描述,以下不再赘述。

需要说明的是,若第二终端(调度终端)支持比例公平调度算法,则第二终端在为第一终端(即被调度终端)分配资源时,相较于不支持比例公平调度算法的第二终端为第一终端分配资源来说,可以更合理地分配资源,优化用户体验,同时提高资源利用率。若第二终端支持载波聚合,则第二终端可以在多个载波上为第一终端分配资源,从而提高系统的吞吐量,提高资源分配效率。若第二终端支持并行处理,则第二终端可以同时处理多个进程,从而提高数据处理效率,降低时延。若第二终端支持的最大进程数较多,则第二终端可以调度多个进程,减少初传或重传的等待时间。若第二终端可以在多个天线端口上工作,则可以提高通信系统的空间复用增益或空间分集增益,从而实现合理的资源分配,优化资源分配效率。若第二终端支持较大缓存,则第二终端可以为更多的第一终端分配资源。若第二终端支持的最大发射功率较大,则第二终端可以为较大的范围内的第一终端分配资源。
需要说明的是,至少一个第二终端可以包括如下至少一种类型的第二终端:第二终端可以在侧行链路上,向至少一个第一终端发送第二终端的能力信息。其中,至少一个 第二终端与第一终端之间存在单点对单点业务,如单播业务,或者至少一个第二终端与第一终端之间存在单点对多点业务,如广播、多播或组播业务。本申请实施例对于第一终端的业务的类型和数量,以及与第一终端存在上述业务的第二终端的类型和数量,不作限定。
S302、第二终端发送第一资源配置信息给第一终端,相应地,第一终端接收第二终端发送的第一资源配置信息。
其中,第一资源配置信息用于指示为第一终端分配的资源。可选的,第一资源配置信息是第二终端为第一终端分配的资源。可选的,第一资源配置信息可以通过以下至少一种信令承载:RRC信令、MAC信令、广播消息、系统消息、物理层信令。
由于第二终端具有第二能力,可以作为调度终端为其他终端分配资源,因此第二终端可以根据第二资源配置信息为第一终端分配资源,并发送第一资源配置信息给第一终端,以使得第一终端利用第一资源配置信息中指示的资源与第二终端进行通信。其中,第二资源配置信息为预定义资源,可选地,预定义资源为第二终端位于网络覆盖范围内时,网络设备分配给第二终端的资源,或者预先自定义的资源。示例性地,分配给第二终端的预定义资源为一定长度的带宽。可选的,第二资源配置信息可以通过以下至少一种信令承载:RRC信令、MAC信令、广播消息、系统消息、物理层信令。
可选的,在通信系统中还可以包括网络设备,若第一终端和第二终端均位于网络设备的覆盖范围内,或者第一终端位于网络设备的覆盖范围外,第二终端位于网络设备的覆盖范围内,但第一终端可以接收到第二终端发送的信息时。若第一终端与第二终端进行通信,则第二终端在将其能力信息发送给第一终端后,还发送第一资源配置信息给第一终端,以使得第一终端根据第一资源配置信息中指示的资源与第二终端进行通信。其中,第一资源配置信息可以为第二终端根据第一终端的能力信息以及第二资源配置信息分配给第一终端的资源,也可以为网络设备分配给第一终端的资源。其中第二资源配置信息为网络设备分配给第二终端的资源,也可以为预定义资源。

或者,第一终端与第二终端均位于网络覆盖范围外,第一终端与第二终端之间的通信方法可以参照上述实施例所述,在此不再赘述。
本申请提供的通信方法中,对基于终端调度的资源分配方式的终端的能力进行定义,得到第二能力,第二能力包括作为调度终端分配资源,第二终端具有第二能力。第一终端接收第二终端的能力信息后,可以确定第二终端为调度终端,并由第二终端为该第一终端分配资源。通过上述过程,本申请解决了基于终端调度的资源分配方式中的终端类型设计问题,对调度终端的终端类型进行设计,可以明确终端的角色,使得第一终端根据第二终端上报的能力信息,确定第二终端为调度终端,并由第二终端为第一终端 分配资源,从而优化资源分配的效果,提高资源利用率。
在一种可能的情况下,第一终端发送其能力信息给第二终端,但两个终端之间可能并不需要进行通信,因此,不必为第一终端和第二终端之间的通信分配资源,而在上述实施例中,第二终端在接收到第一终端的能力信息后即为第一终端分配资源,或者转发网络设备分配给第一终端的资源,可能会造成不必要的资源浪费。因此,在步骤S302之前,所述通信方法还可以包括步骤S3021,如图3中的(b)所示,第二终端在接收到第一终端发送的第一资源调度请求后再为第一终端分配资源,或者转发网络设备为第一终端分配的资源,从而减少资源的浪费。
S3021、第一终端发送第一资源调度请求给第二终端,相应地,第二终端接收第一终端发送的资源调度请求。

在本申请实施例中,第二终端在接收到第一终端发送的第一资源调度请求后,再为第一终端分配资源,可以在第一终端与第二终端不需要进行通信时,减少不必要的资源分配过程,从而减少资源的浪费。
可选地,在步骤S302之前,所述通信方法还可以包括步骤S3022,如图3中的(b)所示,以便于第二终端确定第一终端为被调度终端。
S3022、第一终端发送第一终端的能力信息给第二终端,相应地,第二终端接收第一终端的能力信息。

在第一终端与第二终端需要进行通信时,先由第一终端发送第一终端的能力信息给第二终端,然后第二终端在接收到第一终端的能力信息后,根据第一终端的能力信息的取值,确定第一终端为支持接收调度终端(即第二终端)分配的资源/资源池的终端。
需要说明的是,在本申请实施例中,可以先执行步骤S3022,再执行步骤S301和步骤S3021,也可以在步骤S3021和步骤S301之间,执行步骤S3022。另外,在一种可能的实现方式中,第一终端还具备第二能力,和/或第二终端还具备第一能力。
本申请提供的通信方法中,对基于终端调度的资源分配方式的终端的能力进行定义,得到第一能力和第二能力,第一能力包括接收调度终端分配的资源,第二能力包括 作为调度终端分配资源,第一终端具有第一能力,第二终端具有第二能力。第二终端发送其能力信息给第一终端,以使得第一终端确定第二终端为调度终端,并接收第一终端的能力信息,确定第一终端为被调度终端。第一终端接收第二终端的能力信息后,并确定第二终端为与其对应的调度终端后,请求第二终端发送第一资源配置信息,以使得第一终端利用第一资源配置信息指示的资源与第二终端进行通信。通过上述过程,本申请解决了基于终端调度的资源分配方式中的终端类型设计问题,对调度终端和被调度终端的终端类型进行设计,进一步明确各个终端的角色,使得调度终端根据被调度终端的需求为被调度终端分配资源,从而优化资源分配的效果。另外,调度终端与被调度终端之间非统一的终端产品形态设计,使得终端类型层次化,降低数量较多的被调度终端的成本,从而降低整个基于终端调度的资源分配方式的通信系统的成本。
另外,在一种可能的实现方式中,通信系统中包括网络设备、至少一个第一终端以及至少一个第二终端,第一终端具备第一能力和/或第二能力,第二终端具备第一能力和/或第二能力。因此,本申请实施例还提供了一种通信方法,在图3所示的步骤S301之前,还包括步骤S401-S405,如图4所示。图4所示的通信方法的流程示意图,可以应用于图1中的任一终端,如图1的(c)中的终端设备102-终端设备108,或者图2所示的通信装置200,完成与另一终端设备,如图1的(c)中的终端设备102-终端设备108,在侧行链路上的直接通信。如图4所示,该通信方法包括如下步骤:

网络设备接收第二终端发送的第二终端的能力信息,并根据第二终端的能力信息,确定第二终端为调度终端。
具体的,关于第二终端的能力信息的描述可以参照步骤S3022中对第二终端的能力信息的描述。
S402、第二终端发送第二资源调度请求给网络设备,相应地,网络设备接收第二终端发送的第二资源调度请求。
其中,第二资源调度请求用于请求网络设备为第二终端分配资源,第二资源调度请求中包括网络设备的标识、第二终端的标识以及第二终端的业务数据信息。
可选地,网络设备接收到第二终端的第二资源调度请求后,响应于该请求,为第二终端分配资源。
S403、网络设备发送第二资源配置信息给第二终端,相应地,第二终端接收网络设备发送的第二资源配置信息。
其中,第二资源配置信息用于指示网络设备为第二终端分配的资源。
示例性的,网络设备为第二终端分配的资源可以为资源池中的一部分,也可以为整个资源池。
可选地,网络设备也可以向第二终端发送指示信息,指示第二终端发送其能力信息给与其相对应的被调度终端,在本申请实施例中,第二终端为调度终端,第一终端为与第二终端相对应的被调度终端,所述指示信息中包括第一终端的标识,以及第二终端的标识。
S404、第一终端发送其能力信息给网络设备,相应地,网络设备接收第一终端发送的第一终端的能力信息。
网络设备根据接收到的第一终端的能力信息,确定第一终端为被调度终端。
关于第一终端的能力信息的描述可以参见步骤S301中的描述。
示例性的,以RRC信令为例,第一终端根据其能力信息01、第一终端的标识、以及网络设备的标识生成RRC信令,并根据RRC信令中的网络设备的标识,通过侧行链路将RRC信令发送给网络设备。网络设备根据接收到的RRC信令中第一终端的能力信息01以及第一终端的标识,确定第一终端具有第一能力,即第一终端可以作为被调度终端接收调度终端分配的资源,第一终端的能力信息中还可以包括第一终端的标识。
S405、网络设备发送指示信息给第一终端,相应地,第一终端接收网络设备发送的指示信息。
其中,指示信息用于指示第一终端发送第一终端的能力信息给调度终端。在本实施例中,第二终端为调度终端。
需要说明的是,在本申请实施例中,可以先执行步骤S401-S403,再执行步骤S404-S405,也可以,先执行步骤S404-S405再执行步骤S401-S403。对于步骤S401与步骤S402来说,也可以先执行步骤S402,再执行步骤S401。
在本申请实施例中,对基于终端调度的资源分配方式的终端的能力进行定义,将各个终端的能力信息发送给网络设备,使得网络设备根据各个终端的能力信息确定调度终端,以及与调度终端相对应的被调度终端,进而使得具备第二能力的第二终端作为调度终端为第一终端分配资源。通过上述过程,本申请解决了基于终端调度的资源分配方式中的终端类型设计问题,并描述了由网络设备根据能力信息确定用于为其他终端分配资源的调度终端的技术方案,解决了新类型的终端的通信问题。
需要说明的是,图3-图4所示的通信方法中涉及到了三种不同的终端类型,包括接收调度终端分配的资源的终端、作为调度终端为其他终端分配资源的终端、以及既可以作为被调度终端接收调度终端分配的资源,也可以作为调度终端为其他终端分配资源的终端。上述终端类型的设计可以很好的解决基于终端调度的资源分配方式中的终端类型设计的问题,这种设计方式较为复杂,设计成本较高,因此适用于所包含的终端数量较多的通信系统,不适用于所包含的终端数量较少的通信系统。
因此,为了解决上述技术方案不适用于所包含的终端数量较少的通信系统的问题,本申请还提供了另一种可能的实现方式。对终端类型进行设计,使得终端既可以作为被调度终端接收调度终端分配的资源,也可以作为调度终端分配资源,从而定义一种第三能力,第三能力包括支持基于终端调度的资源分配方式。因此,基于终端调度的资源分配方式中的终端至少具有第三能力,可选的,第三能力还包括上述实施例中的第一能力和第二能力。在本申请实施例中,通过能力信息表示终端所具备的能力。
示例性的,能力信息的一种实现方式如表3所示。
表3
field state description
00 不支持基于终端调度的资源分配方式
01 支持基于终端调度的资源分配方式
表3中,能力信息以2bit字符表示,能力信息的不同取值表示终端具备不同的能力。例如:当终端的取值为00时,表示终端不支持基于终端调度的资源分配方式。当能力 信息的取值为01时,表示终端支持基于终端调度的资源分配方式即终端具有第三能力。
示例性的,以发送能力信息的终端为发送方终端,接收发送方终端发送的能力信息的终端为接收方终端为例,若发送方终端发送的能力信息的取值为00,则接收方终端可以确定发送方终端为不支持基于终端调度的资源分配方式的终端;若发送方终端发送的能力信息的取值为01,则接收方终端可以确定发送方终端为不支持基于终端调度的资源分配方式的终端。
结合上述另一种基于终端调度的资源分配方式的终端类型的设计方案,本申请实施例中的第一终端发送的第一终端的能力信息或第二终端发送的第二终端的能力信息,用于指示第一终端或第二终端是否具有第三能力,若具有第三能力,则可以由网络设备指定其作为调度终端或者被调度终端。
