下面结合说明书附图对本发明实施例作进一步详细描述。
参见图 3所示, 本发明实施例提供的一种 D2D通信中的资源配置方法, 包括以下步骤:
步骤 31、网络侧艮据 D2D通信的业务特性和网络中资源的当前使用状况, 为已建立的 D2D通信组中的 D2D终端配置用于 D2D通信的 D2D资源; 具体的, 该 D2D通信组中包含至少两个已建立了 D2D通信链路的 D2D 终端, 该 D2D通信组中的任意两个 D2D终端均能进行 D2D通信。
步骤 32、 网络侧将已配置的 D2D资源的配置信息发送给该 D2D通信组 中的每个 D2D终端, 以使每个所述 D2D终端根据对所述 D2D资源的占用方 式使用所述 D2D资源进行 D2D通信; 其中,该 D2D通信中的各 D2D终端对 已配置的 D2D资源的占用方式, 由网络侧确定并通知给每个 D2D终端,或者 由该 D2D通信组中的 D2D终端确定。 这里的 "D2D资源的占用方式" 是指 D2D终端占用哪个或哪些 D2D资源, "D2D资源的占用方式" 可通过资源图 样(pattern )的形式指示出来, 也可以通过预先约定的方式来规定, 还可以通 过其他方式来指示或规定, 具体内容可参见下面的描述。
本发明实施例提出一种网络侧对 D2D通信所使用资源进行配置的方法, 在网络的控制之下,使得 D2D通信组中的各 D2D终端之间能够更灵活的利用 D2D资源, 从而降低了 D2D通信和传统蜂窝通信之间的干扰, 提高了系统整 体的吞吐量, 也提高了用户体验。
优选的, 网络侧采用无线资源控制( Radio Resource Control , RRC )信令 为该 D2D通信组配置用于 D2D通信的 D2D资源。
优选的,网络侧为该 D2D通信组配置的 D2D资源在设定时长内或在去激 活之前用于 D2D通信, 即网络侧采用半静态配置为该 D2D通信组配置用于 D2D通信的 D2D资源。
进一步, 网络側在进行半静态配置时, 还可以携带用于指示该资源配置 的有效的时间范围的指示信息。 具体的, 若当前时间不在该资源配置的有效 的时间范围内, 则该资源配置失效, 或者在接收到网络侧发送的针对该资源 配置的去激活命令之后, 该资源配置失效。
在实施中, 步骤 31中, 若网络侧确定两个 D2D UE或者一组 D2D UE之 间建立了 D2D通信链路,则: 网络侧根据 D2D通信的业务特性和网络中资源 的当前使用状况, 为已建立的 D2D通信组中的 D2D终端配置用于 D2D通信 的 D2D资源。
例如, 该 D2D 通信组的 D2D 通信的业务具有典型的保证比特率 ( Guaranteed Bit Rate, GBR )业务特性, 例如视频对话业务等, 具有特定的 传输速率要求, 则该网络侧决定为该 D2D通信组中的 D2D终端配置 D2D资 源以供 D2D通信使用。
又如,该 D2D通信组的 D2D通信的业务为数据下载类,例如文件传输协 议(File Transport Protocol, FTP )等, 虽然没有 GBR要求, 但在整个传输周 期内, 数据传输速率要求较固定, 例如下栽 20M的文件, 则该网络侧可以根 据设定的资源调度算法、 网络中资源当前使用情况以及该 D2D 通信组中的 D2D UE签约的用户速率要求, 为该 D2D通信組分配用于 D2D通信的 D2D 资源, 以供数据传输使用。
再如, 当网络资源较宽松, 或者当前已配置为经由核心网的通信路径的 资源在指定时间范围内可以被 D2D通信所复用, 例如该资源已经被半静态的 分配给一个经由核心网络进行通信的 UE, 并且该 UE的传统通信链路(即经 由核心网的通信路径 )与 D2D链路之间千扰较小, 符合设定的复用规则, 则 该网络侧可以对该部分资源进行复用, 在指定时间内将该部分资源配置给该 D2D通信組以供 D2D通信使用, 从而节省网络动态调度 D2D资源的控制信 令开销。
再如, 当网络侧(如 eNB ) 的控制信令开销占用较大, 且该 D2D通信组 的 D2D通信业务可以忍受一定的时延时,该网络侧也可以给该 D2D通信组配 置半静态的 D2D资源 , 以节省控制信令的开销。
优选的, 步骤 31中, 网络侧为已建立的 D2D通信组中的 D2D终端配置 半静态的 D2D资源, 该 D2D资源在设定时长内或者在进行去激活之前用于 D2D通信。
在实施中,网络侧为 D2D通信组配置的 D2D资源的一种优选的配置方式 如下:
频点 +时频资源具体位置 +时域上对应的资源图样( pattern ); 或者, 频点十时频资源具体位置十重复周期。
需要说明的是,网络侧可以在同一个频点上为该 D2D通信组配置 D2D资 源, 也可以在不同频点上为该 D2D通信组配置 D2D资源; 网络侧为 D2D通 信组配置的 D2D资源的重复周期可以全部相同, 也可以部分相同, 还可以全 不相同。
在实施中, 一种优选的资源配置方式是, 步骤 31 中, 网络侧为该 D2D 通信组配置多种用于 D2D通信的 D2D资源的配置, 并将为该 D2D通信组配 置的所有种类的 D2D资源的配置信息均发送给每个 D2D终端。
优选的, 不同种类配置包含的 D2D资源的大小具有差别, 如不同种类配 置提供不同的传输速率, 以应对数据量的变化。
例如, 网络侧可以通过 RRC信令提供以下两种不同的配置:
第一种配置包含资源块 1和资源块 2, 重复周期均为 T;
第二种配置仅包含资源块 2, 重复周期为 T。
上述两种配置中, 第一种配置所占用的资源较多, 能够提供的传输速率 较高, 第二种配置相比于第一种配置, 其所占用的资源较少, 能够提供的传 输速率较小。
又如, 网络侧可以通过 RRC信令提供以下两种不同的配置:
第一种配置包含资源块 1 , 重复周期均为 T;
第二种配置包含资源块 2, 重复周期为 2T。
上述两种配置中, 第一种配置所占用的资源较多, 能够提供的传输速率 较高, 第二种配置相比于第一种配置, 其所占用的资源较少, 能够提供的传 输速率较小。
需要说明的是, 该 D2D通信組的多种 D2D资源的配置, 在同一个时刻, 只能使用其中的一种 D2D资源的配置。
若网络侧为 D2D通信组配置了多种用于 D2D通信的 D2D资源的配置, 则:网络侧与 D2D通信組可以预先约定初始时使用的 D2D资源的配置;或者, 网络侧指示该 D2D通信组当前处于激活状态的 D2D资源的配置。
具体的,网络侧可以预先与 D2D通信組的 D2D终端约定初始时使用的配 置; 例如, 网络侧通过 RRC信令向该 D2D通信组的每个 D2D终端发送 5种 D2D资源的配置, 网络侧与 D2D通信組的 D2D终端预先约定初始时使用第 一种资源配置进行 D2D通信 ,则每个 D2D终端在初始时均使用第一种资源配 置。
网络侧还可以在向该 D2D通信组发送为其配置的所有 D2D资源的配置 时, 指示该 D2D通信组的 D2D终端当前处于激活状态的 D2D资源的配置; 例如, 该网络侧通过 RRC信令向该 D2D通信组发送 5种 D2D资源的配置, 并通过该 RRC信令指示该 D2D通信组的 D2D终端初始时都使用第一种 D2D 资源的配置进行 D2D通信。
网络侧还可以通过 RRC信令向该 D2D通信组发送为其配置的所有资源 配置之后,再通过 L2/L1信令指示该 D2D通信组的 D2D终端当前处于激活状 态的 D2D资源的配置, 以使每个 D2D终端当前都使用采用激活状态的 D2D 资源的配置进行 D2D通信。 优选的, L2 ( Layer 2 )信令主要指媒体接入控制 ( Media Access Control, MAC )信令, 具体以媒体接入控制层控制单元(MAC Control Element, MAC CE ) 的形式承载; LI ( Layer 1 )信令主要指物理层信令, 具体以物理下行控 制信道(Physical Downlink Control Channel, PDCCH ) 的形式 ? 栽。
在实施中, 网络侧与 D2D通信组可以约定采用编号的形式标识多种 D2D 资源的配置, 如编号 0表示第一种 D2D资源的配置, 编号 1表示第二种 D2D 资源的配置,依次类推 , 这样, 网络侧在指示该 D2D通信组的 D2D终端当前 处于激活状态的 D2D资源的配置时, 仅需携带该资源配置对应的编号即可。
进一步,在网络侧向该 D2D通信组发送为其配置的所有 D2D资源的配置 之后 ,该网络侧还可以通过 L2/L1信令通知该 D2D通信组中的各 D2D终端暂 停使用任一种 D2D资源的配置, 等待该网络侧对资源配置的动态调度。
在实施中,若网络侧仅为该 D2D通信组配置了一种用于 D2D通信的 D2D 资源的配置, 则: 该网络侧可以先通过 RRC信令为该 D2D通信组配置 D2D 资源,再通过 L2/L1信令向该 D2D通信组中的每个 D2D终端发送激活该资源 配置的指示或去激活该配置的指示。
在实施中,若网络侧确定该 D2D通信組的 D2D通信的业务特性发生变化 (如 D2D链路上增加或减少了一个 D2D通信业务)或网络中资源的当前使用 状况发生变化, 为了适用当前的 D2D通信业务的要求, 该方法还包括:
网络侧为该 D2D通信组中的 D2D终端重新配置用于 D2D通信的 D2D资 源; 以及, 网络侧将重配置信息发送给该 D2D通信组中的每个 D2D终端, 并 将所述重配置信息的生效时刻指示给每个 D2D终端。
具体的, 重配置信息的生效时刻一般以绝对时刻为准, 例如, 该重配置 信息的生效时刻可以是系统帧号(System Frame Number, SFN )。
网络侧可以在向该 D2D通信组中的每个 D2D终端发送该重配置信息时, 携带用于指示该重配置信息的生效时刻的指示信息, 也可以在向该 D2D通信 組中的每个 D2D终端发送该重配置信息之后,通过 L2/L1信令向每个 D2D终 端发送用于指示该重配置信息的生效时刻的指示信息。 需要说明的是, 上述配置和重配置过程中, 均是每个 D2D UE的服务小 区分別对其服务的每个 UE进行信令配置。 如杲该 D2D通信組中的 D2D UE 的服务小区归属于同一个 eNB , 则该 eNB根据自身内部的资源调度算法就可 以决定 D2D资源的分配情况; 如杲该 D2D通信组中的 D2D UE的 良务小区 归属于两个或两个以上的 eNB,则在决定 D2D资源分配时, 不同 eNB之间需 要进行交互和协商, 以统一资源分配的情况和其它相关配置(如主 UE的标识 信息, 反馈配置, 设定的占用规则等信息)。
优选的,若该 D2D通信组中的各 D2D UE的服务小区归属的不同 eNB对 应于同一个控制节点,则在对该 D2D通信组的用于 D2D通信的资源配置和其 它相关配置的过程中, 可以由该控制节点进行统一的决策和管理, 再分别向 每个 D2D UE的服务 eNB发送资源配置信息和其它配置信息, 最后由各服务 eNB将资源配置信息发送给相应的 D2D UE。
在实施中, 该 D2D通信組中的每个 D2D终端对网络侧为该 D2D通信组 配置的 D2D资源的占用方式, 包括以下两种确定方式:
方式 A、 由网络侧确定该 D2D通信組中的每个 D2D终端对配置的 D2D 资源的占用方式, 并通知给每个 D2D终端。
在实施中, 方式 A进一步又包括以下两种方式:
方式 A1、 对于为该 D2D通信组配置的 D2D资源, 网络侧显式指示自身 为每个 D2D终端指定的用于发送数据的发送资源, 具体为:
网络侧在配置 D2D资源时,为每个 D2D终端指定用于发送数据的发送资 源;网络侧将自身为每个 D2D终端分配的发送资源发送给 D2D通信组中的所 有 D2D终端。 相应的, 针对 D2D通信组中的每个 D2D终端, D2D终端在接 收到网络侧为该 D2D通信组中的每个 D2D终端指定的发送资源之后,在该网 络侧为自身指定的发送资源上发送数据, 在网络侧为该 D2D通信组中除自身 之外的其他 D2D终端指定的发送资源上接收数据。
该方式下, 网络侧在决定为该 D2D 通信組配置用于 D2D通信的 D2D资 源时, 可以同时对 D2D资源与每个 D2D UE之间的对应关系进行规定, 或者 分别为每个 D2D UE分配专用的 D2D资源, 网络侧将为每个 D2D UE分配的 D2D资源的信息发送给该 D2D通信组中的所有 D2D UE。
例如, 假设该 D2D通信組中包含两个已建立 D2D链路的 D2D UE, 即 UE1和 UE2 , 网络侧为该 D2D通信組分配的 D2D资源集合为 {资源 A , 资源 B} , 其中, D2D资源的重复周期 T (当然, 这里的重复周期也可以是比较复 杂的形式, 比如不同的资源有不同的重复周期, 或者不同的资源有不同的图 样 ( pattern ),例如资源 A仅在 SF 为奇数的无线帧有效, 而资源 B仅在 SFN 为偶数的无线帧有效),则该网络侧可以在配置信令里显式指示资源 A由 UE1 使用(即 UE1在资源 A上进行数据发送,则 UE2在资源 A上进行数据接收), 类似的, 该网络侧可以在配置信令里显式指示资源 B 由 UE2使用 (即 UE2 在资源 B上进行数据发送, 则 UE1 在资源 B上进行数据接收)。
又如, 假设该 D2D通信組中包含两个已建立 D2D链路的 D2D UE, 即 UE1和 UE2, 网络侧为 UE1分配了用于 D2D通信的资源 A以及为 UE2分配 了用于 D2D通信的资源 B,其中,该资源 A具有指定的重复 pattern或者重复 周期 Tl, 该资源 Β具有指定的重复 pattern或者重复周期 T2, 则该网络在发 给 UE1和 UE2的资源配置信令中, 除了包含本 UE的 D2D资源的分配信息, 还包含对方 UE的 D2D资源的分配信息, 以便于当本 UE在该网络侧为自身 分配的 D2D资源上发送数据的时候, 对方 UE能够在相同的资源上进行数据 接收。
需要说明的是,上述两个举例说明中,仅以 D2D通信组包含两个 D2D UE 为例进行说明的, 该 D2D通信组中包含两个以上的 D2D UE时, 为每个 D2D UE进行 D2D资源的分配过程是类似的, 即该网络侧为该 D2D通信组中每个 需要进行 D2D通信的 D2D UE分配 D2D资源, 并将所有 D2D UE的 D2D资 源的分配信息发送给该 D2D通信组中涉及的所有 D2D UE。
方式 A2、 网络侧与该 D2D通信組预先约定对 D2D资源的占用方式, 或 网络侧为该 D2D通信组配置资源占用图样( pattern )并将该资源占用图像发 送给每个 D2D终端, 以指示每个 D2D终端根据该资源占用图样使用 D2D资 源。
该方式下, 若网格侧与该 D2D通信组预先约定了 D2D资源的占用方式, 则该网络侧为该 D2D通信组的 D2D终端配置了用于 D2D通信的 D2D资源之 后, 将该 D2D资源的配置信息发送给每个 D2D终端; 相应的, 每个 D2D终 端在接收到该 D2D资源的配置信息后, 采用预先预定的占用方式(如轮换使 用), 使用该 D2D资源进行通信。
该方式下, 网络侧为该 D2D通信组配置资源占用图样具体为: 网络侧在为 D2D通信組配置 D2D资源之后, 为该 D2D通信组配置资源 占用图样, 该资源占用图样用于指示每个 D2D终端对 D2D资源的占用方式, 即为每个 D2D终端指示该终端所占用的 D2D资源;网络侧将该资源占用图样 发送给每个 D2D终端,其中,每个 D2D终端采用网络侧配置的资源占用图样 使用 D2D资源。
优选的, 网络侧可以在同一条 RRC信令中将 D2D资源的配置信息以及 资源占用图样发送^ 个 D2D终端;网络侧也可以先将 D2D资源的配置信息 发送给每个 D2D终端 , 再通知每个 D2D终端该资源占用图样。
该方式下, 当网络侧决定为该 D2D通信組中的 D2D UE配置 D2D资源 时, 可以同时对该 D2D通信组内各 D2D UE对 D2D资源的占用规则进行规 定, 得到每个 D2D终端对应的资源占用图样。
例如, 将每个子帧里的资源块作为一个 D2D资源, 由所有 D2D UE交替 使用每个 D2D资源发送数据。 并且在进行 D2D资源配置时, 同时规定所有 D2D UE的使用顺序,如给每个 D2D UE进行编号,按照编号从小到大的顺序 使用该 D2D资源。 以该 D2D通信组包含两个 D2D UE为例, 假设网络侧为 该 D2D通信组分配了子帧 3和子帧 6中的资源作为用于 D2D通信的 D2D资 源,该网络侧通知给各 D2D终端的资源占用 pattern可以是,编号为 1的 UE1 使用子帧 3中的 D2D资源, 编号为 2的 UE2使用子帧 6中的 D2D资源。
又如, 若 UE1和 UE2需要发送的数据量不对称, 网络侧为该 D2D通信 組分配了子帧 3, 子帧 6及子帧 8中的资源作为用于 D2D通信的 D2D资源, 在每个无线帧里,子帧 3和子帧 6 ,子帧 8分别包含一个用于 D2D通信的 D2D 资源, 则该网络侧通知给各 D2D终端的资源占用 pattern可以是, 编号为 1的 UE1使用子帧 3和子帧 6中的 D2D资源, 编号为 2的 UE2使用子帧 8中的 D2D资源。
再如,将每个子帧内的资源块划分成多个 D2D资源,如若该 D2D通信组 包含 4个 D2D UE, 网络侧为该 D2D通信组分配了子帧 3和子帧 6中的资源 作为用于 D2D通信的 D2D资源, 其中子帧 3中的资源被划分为 2个 D2D资 源,子帧 6的资源也被划分为 2个 D2D资源,则网络侧为该 D2D通信组中各 D2D UE配置的资源占用 pattern可以是,编号为 1的 UE1 和编号为 2的 UE2 按照设定顺序使用子帧 3中的两个 D2D资源发送数据,编号为 3的 UE3和编 号为 4的 UE4按照设定顺序使用子帧 6中的两个 D2D资源发送数据。
表 1给出了网絡侧配置的资源占用图样的一个具体实现形式的实例: 表 1
Figure imgf000015_0001
需要说明的是, 表 1 只是用于说明该资源占用图样的, 并不限制该资源 占用图样的具体实现形式, 该资源占用图样也可以釆用其他实现形式。
该方式下,网络侧可以为该 D2D通信組中的所有 D2D终端配置一个用于 指示各 D2D终端对 D2D资源的占用情况的资源占用图样, 也可以针对每个 D2D终端配置一个用于指示该 D2D终端对 D2D资源的占用情况的资源占用 图样。
方式 B、由 D2D通信组中的 D2D终端确定每个 D2D终端对已配置的 D2D 资源的占用方式;
在实施中, 方式 B进一步又包括以下两种实现方式:
方式 B1、 由网络侧选定一个主 D2D终端, 由该主 D2D终端针对该 D2D 通信组中的每个 D2D终端, 对该网絡侧为该 D2D通信组配置的 D2D资源进 行调度, 具体为:
网络侧从该 D2D通信組中, 选定一个 D2D终端作为主 D2D终端, 并将 选定的主 D2D终端的标识信息通知给该 D2D通信組中的每个 D2D终端, 其 中, 该主 D2D终端用于在该 D2D通信組内调度该网络侧配置的 D2D资源。
该方式下, 当网络侧决定为该 D2D通信组中的 D2D终端配置用于 D2D 通信的 D2D资源时, 也可以同时为该 D2D通信組配置一个主 D2D终端, 并 显式指示该 D2D通信组中的每个 D2D终端, 由该主 D2D终端来决定对已配 置的 D2D资源的调度。
下面给出该方式下的一种优选的具体实现方式:
网络侧在给 D2D通信组中的 D2D UE配置 D2D资源时,同时配置主 D2D UE,并通知该 D2D通信组中的所有 D2D UE该主 D2D UE的标识信息, 以使 该 D2D通信組中的每个 D2D UE能够获知哪个 D2D UE为网絡侧配置的主 D2D UE。
相应的, 该 D2D通信組中的每个 D2D UE接收到该网络侧配置的 D2D 资源以及指示后, 确定该 D2D通信组中的主 D2D UE。 进一步, 当该 D2D通 信組中的任一 D2D UE需要发送数据时, 该 D2D UE向主 D2D UE发送资源 请求和 /或上报待发送的数据量; 该主 D2D UE在接收到其他 D2D UE发送的 资源请求和 /或上报的待发送的数据量后, 根据设定的调度规则, 对网络侧配 置的 D2D资源进行分配, 为该 D2D通信组中的 D2D UE分配用于发送数据 的发送资源, 并将 D2D资源的分配情况发送给每个 D2D UE; 该 D2D通信组 中的 D2D UE根据接收到的 D2D资源的分配情况, 在该主 D2D UE为自身分 配的发送资源上进行数据的发送, 在该主 D2D UE为除自身之外的其他 D2D UE分配的发送资源上接收其他 D2D UE发送的数据。
进一步, 主 D2D UE在对网络侧配置的 D2D资源进行调度时, 还综合考 虑该 D2D通信组内所有 D2D UE的数据量和各自的优先级等信息。
例如, 主 D2D UE按照该 D2D通信组中的各 D2D UE的优先级从高到低 进行 D2D资源的调度, 即主 D2D UE先调度高优先级的 D2D UE发送数据, 所有高优先级的 D2D UE全部发送完毕, 再调度低优先级 UE发送数据。 又如, 每个优先级 D2D UE均分配有一个 GBR (保障比特速率), 在主 D2D UE确定其他 D2D UE发送的资源请求发生冲突时, 先保证高优先级的 D2D UE达到保障比特速率,剩余的 D2D资源保证 4氏优先级的 D2D UE的保 障比特速率, 如果还有剩余的 D2D资源, 再按照优先级由高到低进行分配。
优选的, 网络侧可以在 D2D资源的配置信令(如 RRC信令) 中携带选 定的主 D2D终端的标识信息; 也可以向通过 RRC信令为该 D2D通信组配置 D2D资源,再通过 L2/L1信令通知该 D2D通信组中的每个 D2D终端该主 D2D 终端的标识信息。
在实施中, 为了便于实现, 优选的 , 该 D2D通信組的 D2D终端可以在预 先设定的时刻和设定的资源上, 发送资源请求和 /或上报待发送的数据量。
例如,在每个无线帧的最后一个分配给该 D2D通信组的 D2D资源上,各 D2D UE按照设定顺序发送资源请求和 /或上报待发送的数据量; 若某个 D2D UE没有数据需要发送, 可以不发送资源请求或上报待发送的数据量, 也可以 上报待发送的数据量为 0。
在实施中, 为了便于实现, 优选的, 该主 D2D终端可以在设定的时刻和 设定的资源上,向该 D2D通信组中的每个 D2D终端发送下一段时间内的 D2D 资源的调度情况; 例如, 在每个无线帧的第一个分配给该 D2D通信组的 D2D 资源上,由主 UE向该 D2D通信组中的每个 D2D终端发送下一个无线帧内的 D2D资源的调度情况。
在实施中, 可以将该 D2D通信組内的每个 D2D UE进行编号, 并对网络 侧为该 D2D通信组配置的 D2D资源也进行编号, 在主 D2D UE对 D2D资源 进行调度时, 可以采用 D2D资源的编号来指示为每个 D2D UE分配的 D2D 资源。
例如, 假设该 D2D通信组内包含两个 D2D UE, 编号分别为 0和 1, 其 中 UE0为主 UE, 在一个无线帧中, 网络侧分配给该 D2D通信組的资源为资 源 1 (子帧 1 ), 资源 2 (子帧 3 ), 资源 3 (子帧 8 ), 则主 D2D UE根据其他 D2D UE上报的待发送的数据量及自身待发送的数据量,在一个无线帧内,将 资源 1分配给 UE1, 将资源 2分配给 UE0以及将资源 3分配给 UE1。
方式 B2、由该 D2D通信组中的各 D2D终端协商确定每个 D2D终端对已 配置的 D2D资源的占用方式, 具体为:
网络侧指示所述 D2D通信组中的每个 D2D终端由各 D2D终端采用协商 方式确定每个 D2D终端对已配置的 D2D资源的占用方式。
该方式下 , 当网络侧决定为该 D2D通信组配置用于 D2D通信的 D2D资 源时, 关于该 D2D通信组内各 D2D UE如何使用已配置的 D2D资源, 由各 D2D UE之间进行协商。
优选的,网络侧可以采用以下方式指示该 D2D通信组中的每个 D2D终端 采用协商方式确定对已配置的 D2D资源的占用方式:
方式 1、 若网络侧在发送 D2D资源配置信息的信令(如 RRC信令)中还 携带主 D2D终端的标识信息, 则指示该 D2D通信组中的每个 D2D终端由主 D2D终端确定每个 D2D终端对已配置的 D2D资源的占用方式;
若网络侧在发送 D2D资源配置信息的信令中未携带任何标识信息, 则指 示该 D2D通信組中的每个 D2D终端采用协商方式确定对已配置的 D2D资源 的占用方式。
方式 2、 网络侧在向该 D2D通信组中的每个 D2D终端发送 D2D资源的 配置信息之后, 向每个 D2D终端发送指示信息, 以指示每个 D2D终端采用协 商方式确定对已配置的 D2D资源的占用方式。
相应的, 该 D2D通信組内的各 D2D终端在接收到网络侧配置的 D2D资 源, 且确定釆用协商方式对已配置的 D2D资源进行调度时, 釆用下列方式中 的一种或组合对已配置的 D2D资源进行调度:
方式一、 D2D终端在确定需要发送数据时, 向 D2D通信组中除自身之外 的其他 D2D终端发送资源申请; D2D终端在接收到至少一个其他 D2D终端 发送的肯定确认(如 ACK消息)后, 在自身所申请的 D2D资源上发送数据, 且在除自身所申请的 D2D资源之外的 D2D资源上接收数据; 其中, D2D终端发送资源申请时, 根据自身需要发送的数据量以及设定 的最大资源限制, 确定需要申请的资源的数量。
该方式下 , 对于该 D2D通信組中的 D2D UE对 D2D资源的占用方式, 设定每次占用的最大资源限制, 例如, D2D终端每次进行资源申请时, 最多 申请占用 2个子帧的 D2D资源,以避免任一 D2D终端无限制占用 D2D资源, 而造成其他 D2D UE无法占用资源的情况;
该 D2D UE先通过广播方式通知所有的 D2D UE,自己将占用 1~2个子帧 中的 D2D资源,或者占用一个子帧中的部分 D2D资源(如该子帧中的前半块 物理资源块( Physical Resource Block, PRB ) ); 若该 UE发送的广播消息被该 D2D通信组内的任一其他 D2D UE进行肯定确认(可以采用单播或者广播的 信令反馈 )的反馈, 则该 D2D UE可以在自身所申请的 D2D资源上进行数据 的发送, 而其它 D2D UE可以在该 D2D资源上进行数据的接收;
若该 D2D UE的资源申请发生冲突, 即两个或者两个以上的 D2D UE进 行了相同或者有部分重叠的 D2D资源的申请, 则该些 D2D UE的资源申请发 生了冲突, 发送了该资源申请的 D2D 不会反馈肯定确认, 即发生了冲突的 D2D UE均不会接收到彼此的肯定确认,此时,该些发生冲突的 D2D UE都不 能使用所申请的 D2D资源。
进一步, 可以采用以下任一方式解决资源申请的冲突:
第一种方式、 由发送资源申请的 D2D终端解决该冲突, 具体为: 若 D2D终端在向 D2D通信组中除自身之外的其他 D2D终端发送资源申 请后,未接收到任何 D2D终端发送的肯定确认,则该 D2D终端确定自身发送 的资源申请与其他 D2D终端的资源申请发生冲突;
该 D2D终端随机选择时延(如随机的回传(backoff ) 时延)) 并重新向 D2D通信组中除自身之外的其他 D2D终端发送资源申请; 或者, 该 D2D终 端根据设定的占用方式, 决定是否占用所申请的 D2D资源。
其中, 设定的占用方式包括但不限于以下方式:
根据每个发生冲突的 D2D终端的优先级,由优先级高的 D2D终端使用所 申请的 D2D资源; 或者,
根据每个发生冲突的 D2D在设定时长内占用所述 D2D资源的情况,由占 用 D2D资源最少的 D2D终端使用所申请的 D2D资源, 例如, 由较长时间未 进行数据发送的 D2D终端使用所申请的 D2D资源; 或者,
按照约定方式轮换使用所申请的 D2D资源。
需要说明的是, 上述只是列举了几种优选的占用方式, 本发明实施例还 可以采用其他占用方式解决冲突, 如按照 D2D UE的编号从小到大的顺序, 轮换使用所申请的 D2D资源, 此处不在——列举。
举例说明, 以两个 D2D UE的资源申请发生冲突为例, 即 UE1与 UE2 , 则 UE1及 UE2均不会收到对方的肯定确认, 此时 UE1及 UE2均知道自身的 资源申请发生冲突了, 其可以采取设定的占用方式进行冲突处理, 例如, UE1 的资源使用优先级高于 UE2的资源使用优先级, 则 UE1及 UE2均默认 UE1 使用该 D2D资源; 又如, 若上一次 UE1使用所申请的 D2D资源进行数据接 收, 则在发生冲突时, UE1及 UE2均默认由 UE1使用该 D2D资源; 再如, 当 UE1及 UE2的资源申请发生冲突时,由 UE1及 UE2轮换使用所申请的 D2D 资源 , 如当前无线帧由 UE1使用该 D2D资源, 下一个无线帧由 UE2使用该 D2D资源, 依次轮换。
第二种方式、由未同时发送具有冲突的资源申请的 D2D终端解决该冲突, 具体为:
该 D2D通信组内的任一 D2D终端确定除自身之外的至少两个 D2D终端 的资源申请发生冲突, 该 D2D终端根据设定的占用方式, 从发生沖突的 D2D 终端中,确定本次使用所申请的 D2D资源的 D2D终端,并通知发生冲突的每 个 D2D终端。
其中, 设定的占用方式包括但不限于以下方式:
根据每个发生冲突的 D2D终端的优先级,由优先级高的 D2D终端使用所 申请的 D2D资源; 或者,
根据每个发生冲突的 D2D在设定时长内占用所述 D2D资源的情况,由占 用 D2D资源最少的 D2D终端使用所申请的 D2D资源, 例如, 由较长时间未 进行数据发送的 D2D终端使用所申请的 D2D资源; 或者,
按照约定方式轮换使用所申请的 D2D资源。
方式二、 D2D终端在正确接收到该 D2D通信組中除自身之外的其他 D2D 终端发送的数据后, 向该其他 D2D终端返回反馈信息, 并在反馈信息中携带 资源占用指示,用以预约占用后续的至少一个 D2D资源;该 D2D终端在已预 约的 D2D资源上发送数据 , 且在除该已预约的 D2D资源之外的 D2D资源上 接收数据。
该方式适用于带有接收反馈的机制中, 以两个 D2D UE为例, 假设 UE1 在资源 A上发送数据,若 UE2在该资源 A上正确接收到该 UE1发送的数据, 则向 UE1反馈 ACK消息,并在该反馈 ACK消息的同时,携带资源占用指示, 以预约资源 A之后的 D2D资源的使用。
例如, 该 UE2可以通过该资源占用指示显式指示预约占用该资源 A之后 的一个 D2D资源 (如资源 B ); 相应的, 该 UE1在接收到 UE2反馈的 ACK 消息及资源占用指示后, 在下一个 D2D资源(即资源 B )接收 UE2发送的数 据; 如果 UE1在接收到 UE2反馈的 ACK消息的同时, 没有携带资源占用指 示,则 UE1如果还有数据需要发送,则继续使用下一个 D2D资源(即资源 B ) 发送数据。类似的, D2D UE还可以通过资源占用指示预约后续的连续多个子 帧的 D2D资源。
该方式下,若至少两个 D2D终端预约了相同的 D2D资源, 即该至少两个 D2D终端发生冲突, 则接收到该至少两个 D2D终端反馈的 D2D终端可以采 用以下方式解决该冲突:
根据设定的占用方式, 从发生冲突的所有 D2D终端中, 确定本次使用所 预约的 D2D资源的 D2D终端 , 并通知发生冲突的每个 D2D终端。
其中, 设定的占用方式包括但不限于以下方式:
根据每个发生冲突的 D2D终端的优先级,由优先级高的 D2D终端使用所 预约的 D2D资源; 或者, 根据每个发生冲突的 D2D在设定时长内占用所述 D2D资源的情况,由占 用 D2D资源最少的 D2D终端使用所预约的 D2D资源, 例如, 由较长时间未 进行数据发送的 D2D终端使用所预约的 D2D资源; 或者,
按照约定方式轮换使用所预约的 D2D资源。
方式三、 D2D终端在发送的数据中携带用于表示自身需要发送的数据的 剩余量的指示或者在最后一次发送的数据中携带用于表示数据已全部发送的 指示, 其中, 该 D2D通信组的其他 D2D终端在确定该 D2D终端的数据已发 送完毕之后, 采用轮替方式或抢占方式对后续的 D2D资源进行占用。
具体的, 当任一 D2D UE成功抢占了 D2D资源, 并开始在该 D2D资源 上向其他 D2D UE发送数据时, 可以在发送的数据后面携带待发送数据的剩 余量; 由于每个 D2D UE的数据发送情况(包括调制编码格式等), 该 D2D 通信组内的所有 D2D UE都清楚, 因此 D2D UE的数据何时可以发送完毕, 其他 D2D UE可以根据携带的待发送数据的剩余量进行预测;
当任一 D2D UE成功抢占了 D2D资源, 并开始在该 D2D资源上向其他 D2D UE发送数据后, 该 D2D UE在最后一次发送数据时 , 可以携带用于指示 自身的数据已全部发送完毕的指示, 例如, 该 D2D UE可以在层二(L2 ) 的 分组数据汇聚协议 ( Packet Data Convergence Protocol , PDCP )、 和 /或无线链 路控制( Radio Link Control, RLC ), 和 /或媒质接入控制分组数据单元( MAC Packet Data Unit, MAC PDU )的头部中, 利用 lbit的 R比特来指示当前数据 已经全部发送完毕, 例如, 若 R为 1, 则表示数据全部发送完毕。 相应的, 对于当前用于发送数据的 D2D资源的之后的 D2D资源, 其他 D2D UE可以 釆用设定的轮替方式或者抢占方式, 由下一个 D2D UE使用。
基于上述实施例, 本发明实施例还提供了一种 D2D通信中的资源使用方 法, 参见图 4所示, 该方法包括以下步驟:
步骤 41、 D2D通信组中的每个 D2D终端接收网络侧发送的配置信息; 步骤 42、 D2D终端根据接收到的配置信息,确定网络侧为该 D2D通信组 配置的用于 D2D通信的 D2D资源, 并使用该 D2D资源进行 D2D通信; 其中,每个 D2D终端对该 D2D资源的占用, 由网络侧确定并通知给每个 D2D终端, 或者由该 D2D通信组中的 D2D终端确定。
在实施中 , 网络侧为该 D2D通信組配置用于 D2D通信的资源的方式参见 上述网络侧方法的描述, 此处不再赘述。
作为一种实现方式, 步骤 42中, D2D终端使用网络侧配置的 D2D资源 进行 D2D通信, 包括:
D2D终端在接收到网络侧为该 D2D通信组中的每个 D2D终端指定的发 送资源之后, 在该网络侧为自身指定的发送资源上发送数据, 在网络侧为该 D2D通信组中除自身之外的其他 D2D终端指定的发送资源上接收数据,具体 参见上述方式 A1的描述, 此处不再赘述;
