[28]在此,还需要说明的一点是,为了避免因不必要的细节而模糊了本公 开, 在附图中仅仅示出了与根据本公开的方案密切相关的装置结构和 /或 处理步骤, 而省略了与本公开关系不大的其他细节。
[29] 图 1是示意性地示出根据本公开第一实施例的一种无线通信设备的 结构框图。
[30]如图 1所示, 无线通信设备 1用于设备到设备通信, 其包括: 接收装 置 11, 用于接收在与另一无线通信设备之间满足设备到设备通信的预定 条件时发送的寻呼信令,该寻呼信令用于辅助所述无线通信设备和所述另 一无线通信设备之间的寻呼,其中,基于该寻呼信令的寻呼被用于对无线 通信设备 1与另一无线通信设备之间的设备到设备通信的建立进行确定。
[31]根据本公开的一个实施例,可以利用无线通信设备的位置区码( LAC ) 信息判断无线通信设备 1 与另一无线通信设备之间是否满足设备到设备 通信的预定条件。位置区码是为寻呼而设置的区域,通常一个位置区可以 包括一个或多个小区。位置区的划分方式以及位置区码的获取方式是本领 域公知的, 在此不再赘述。 根据本公开的优选实施例, 例如, 当无线通信 设备 1与另一通信设备位于同一位置区时,可以认为无线通信设备 1与该 另一设备之间满足设备到设备通信的预定条件, 从而有可能进行 D2D通 信。 当满足 D2D通信的预定条件时, 可以将无线通信设备 1和另一无线 通信设备确定为潜在 D2D无线通信设备。
[32]但是本公开不限于此,例如也可以在无线通信设备 1与该另一无线通 信设备位于同一小区的情况下,认为无线通信设备 1与该另一无线通信设 备满足设备到设备通信的预定条件。
[33]根据本公开, "小区" 可以包括宏蜂窝 (Macrocell ) 小区、 微蜂窝 ( Microcell ) 小区、 微微蜂窝 (Picocell ) 小区、 家庭基站(HeNodeB; HeNB ) 小区或中继节点 (Relay Node ) 小区等, 但不限于此。 [34]根据本公开的一个实施例,无线通信设备 1可以对应于发起通信的发 起设备,而另一无线通信设备对应于作为该发起设备的通信目标的目标设 备。根据本公开的另一实施例,无线通信设备 1也可以对应于作为通信目 标的目标设备,而另一无线通信设备对应于发起与无线通信设备 1的通信 的发起设备。
[35]通常,可以由例如核心网或者基站(在下面以基站为例进行详细描述) 根据无线通信设备向其发送的位置信息,执行对无线通信设备 1与另一无 线通信设备之间是否满足设备到设备通信的预定条件的判定,并且在满足 设备到设备通信的预定条件的情况下,向无线通信设备发送用于辅助无线 通信设备 1和该另一无线通信设备之间寻呼的寻呼信令。图 2示出包括要 进行 D2D通信的无线通信设备的无线通信系统的示意图。 如图 2所示, 通信系统包括用于 D2D通信的无线通信设备 201和无线通信设备 202以 ^站 203。 无线通信设备 201可以对应于根据本公开实施例的无线通信 设备 1, 无线通信设备 202可以对应于根据本公开实施例的另一无线通信 设备。
[36]如图 2所示,当例如无线通信设备 201作为; ^通信的发起设备向基 站 203发起 D2D通信请求时, 基站 203根据无线通信设备 201以及作为 无线通信设备 201发起的 D2D通信请求的目标的无线通信设备 202的例 如位置区信息, 判断无线通信设备 201和 202是否满足 D2D通信的预定 条件。例如当无线通信设备 201和 202向基站 203发送的位置区信息(例 如位置区码 LAC )显示它们位于同一位置区时, 则确定它们满足 D2D通 信的预定条件, 从而基站 203分别向通信设备 201和 202发送用于辅助 D2D寻呼的寻呼信令。
[37]在确认无线通信设备 201与另一无线通信设备 202之间符合进行 D2D 通信的基本条件之后, 基站 203通过发送针对 D2D通信所设定的寻呼信 令通知无线通信设备 201、 202。 无线通信设备 201、 202接收到从基站下 发的寻呼信令并根据该寻呼信令获得进行 D2D寻呼所需的信息。
[38] 下面仍以图 1 示出的无线通信系统为例对根据本公开实施例的寻呼 信令进行详细描述。
[39]根据本公开的一个实施例,寻呼信令对应的寻呼消息包括以下至少之 一: 关于进行设备到设备通信时使用的专用栽波的信息、关于无线通信设 备和另一无线通信设备的位置区的信息以及用于无线通信设备和另一无 线通信设备的设备到设备通信的专用信道的信道分配信息。
[40]具体地, 在基站 203确认无线通信设备 201与另一无线通信设备 202 之间符合能够进行 D2D通信的基本条件之后, 无线通信设备 201、 202接 收到基站 203下发的物理层下行控制信道(PDCCH ),对 PDCCH中用寻 呼无线网络临时标识(P-RNTI )加扰的下行控制信息(DCI )进行解调, 从而通过 DCI 1C格式的指示, 获知有寻呼消息到达无线通信设备 201、 202。 在此情况下, 无线通信设备 201、 202解调同一子帧的物理下行共享 信道(PDSCH ), 从而获取寻呼消息, 寻呼消息至少包括以下其中之一:
[41]接入参数信息, 即基站定义的、无线通信设备在接入信道进行发送所 需要的信息, 包括用于发送之后进行 D2D通信时所使用的专用载波的信 息;
[42]基站与该无线通信设备通信所使用的频率,其中,即使在开始了 D2D 通信以后,基站与该无线通信设备仍保持控制信道连接, 以防止潜在的链 路恶化以切换回传统通信;
[43] LAC 列表信息, 其提供临近基站的参数信息, 在该信息中携带进行 D2D通信的无线通信设备的 LAC信息,从而为另一无线通信设备提供位 置信息以确定和调整发射功率等;
[44]信道配置信息,其包括该无线通信设备随机接入的基站为其分配的专 用信道的信道配置信息, 以便无线通信设备 201、 202接入该专用信道; 以及
[45] 另一无线通信设备所占用的载波频率(同频或异频), 以便该无线通 信设备调整发射机和接收机的接收频段以保证能正确监听到寻呼。
[46] 虽然以上描述了寻呼消息中包括上述接入参数信息、 LAC 列表信息 以及信道分配信息, 但是本领域技术人员可以理解, 寻呼消息中还包括: 系统参数信息、信道列表信息以及标准的指令信息等,这些信息是本领域 技术人员所公知的, 在此不再赘述。
[47]无线通信设备 201、 202在接收到基站 203发送的寻呼信令之后, 获 得包括之后进行 D2D寻呼所需的信息的寻呼消息, 并基于该寻呼消息选 择调制到基站 203为其分配的 D2D通信的专用信道, 以等待发送和接收 D2D寻呼。
[48] 与基站下发的传统控制信令相比,根据本公开实施例的寻呼信令中承 载了与进行 D2D通信的无线通信设备相关的寻呼消息而省略了一些传统 寻呼消息的承载,从而能够在减少寻呼消息内容的情况下、辅助在随后进 行的 D2D寻呼。
[49]根据本公开的另一实施例,寻呼信令可以至少包括将所述无线通信设 备和所述另一无线通信设备调制到为进行设备到设备通信而设置的专用 载波的跨载波调度指示,无线通信设备通过该跨载波调度指示获知设备到 设备通信的专用载波的信息,并且根据该跨载波调度指示解调得到寻呼信 令对应的寻呼消息。
[50]具体地, 在基站 203确认无线通信设备 201与另一无线通信设备 202 之间能够进行 D2D通信之后, 无线通信设备 201、 202接收基站发送的针 对 D2D通信设定的寻呼信令,以辅助进行 D2D通信的无线通信设备 201、 202之间进行 D2D寻呼。
[51]根据本公开的实施例, 无线通信设备 201、 202在接收到基站下发的 PDCCH对 PDCCH中用 D2D— P-RNTI (用于 D2D通信的寻呼无线网络 临时标识 )加扰的 DCI 1C进行解调。 DCI在通过 D2D— P-RNTI加扰后 为 D2D寻呼的专用格式。 经解调之后的 DCI为 D2D DCI, 其为 D2D寻 呼的专用格式,其具有跨载波调度指示的作用。 DCI中传送的资源块分配 使得用于 D2D通信的无线通信设备 201、 202调制到基站 203为 D2D通 信设置的专用载波的 PDSCH中,从而用于 D2D通信的无线通信设备 201、 202中的每个无线通信设备通过该跨载波指示, 进行跨载波调度以调度到 为 D2D通信设置的专用载波的 PDSCH中进行寻呼消息的解调, 以获得 与寻呼信令对应的寻呼消息。 寻呼消息包括以下至少之一:
[52]基站与该无线通信设备通信所使用的频率,其中,即使在开始了 D2D 通信以后,基站与该无线通信设备仍保持控制信 目连, 以防止潜在的链 路恶化以切换回传统通信;
[53] LAC 列表信息, 其提供临近基站的参数信息, 在该信息中携带进行 D2D通信的无线通信设备的 LAC信息,从而为另一无线通信设备提供位 置信息以确定和调整发射功率等;
[54] 另一无线通信设备所占用的载波频率(同频或异频), 以便无线通信 设备调整发射机和接收机的接收频段以保证能正确监听到寻呼。
[55]无线通信设备 201、 202在接收到基站 203发送的寻呼信令之后, 按 照跨载波调度指示 D2D DCI调制到基站为 D2D进行 D2D通信而设置的 专用载波中, 等待发送和接收 D2D寻呼。
[56] 与基站下发的传统控制信令相比,根据本公开实施例的寻呼信令除了 省略了一些传统的寻呼消息的承载之外, 由于无线通信设备在解调 PDSCH时已经接入了基站为其分配的专用载波, 因此能够进一步减少寻 呼消息的内容, 而直接调制到专用载波进行 D2D通信。
[57]如图 2所示,基于基站 203发送的寻呼信令,无线通信设备 201向作 为通信目标的另一无线通信设备 202发起寻呼。
[58] 图 3示出图 1的无线通信设备 1在作为发起通信的发起设备的一种示 例性结构。
[59] 除了与图 1的无线通信设备 1类似地包括接收装置 11之外, 图 3所 示的无线通信设备 3还包括: 寻呼装置 13, 用于基于关于专用载波的信 息, 在专用载波上发起对另一无线通信设备的寻呼; 以及确定装置 15, 用于根据所述寻呼装置 13的寻呼是否成功, 对所述无线通信设备与所述 另一无线通信设备之间的设备到设备通信的建立进行确定。
[60]在无线通信设备 3的寻呼装置 13向另一无线通信设备发起了寻呼的 情况下,确定装置 15才艮据所述寻呼装置 13的寻呼是否成功,对所述无线 通信设备与所述另一无线通信设备之间的设备到设备通信的建立进行确 定。
[61] 图 4是示意性地示出根据本公开实施例的无线通信设备的又一示例 性结构。
[62] 除了与图 3的无线通信设备 3类似地包括接收装置 11、寻呼装置 13、 确定装置 15之外, 图 4所示的无线通信设备 4还包括: 判断装置 14, 用 于根据该无线通信设备 4是否在第一预定时间段内接收到另一无线通信 设备对于无线通信设备发送的寻呼的确认,来判断无线通信设备的寻呼是 否成功。
[63] 更具体地, 判断装置 14在该无线通信设备 4在第一预定时间段内接 收到该另一无线通信设备的确认的情况下,判断无线通信设备 4的寻呼装 置 13的寻呼成功, 并且在该无线通信设备 4在第一预定时间段内未接收 到该另一无线通信设备的确认的情况下,判断无线通信设备 4的寻呼装置 13 的寻呼失败。 通常, 作为通信目标的另一无线通信设备在接收到无线 通信设备 4的寻呼之后, 将对其发出寻呼确认, 因此, 除了另一无线通信 设备接收到无线通信设备的寻呼之外,也可以将发出寻呼的无线通信设备 4收到寻呼确认作为判断寻呼是否成功的标准。 此外, 本领域技术人员可 以理解,根据本公开实施例的第一预定时间段可以考虑通信设备的位置信 息等因素而任意设定。
[64]造成寻呼失败的原因例如包括以下至少之一:另一无线通信设备所在 的位置区更新、 小区重选、 小区更新; 另一无线通信设备所在小区状态异 常; 另一无线通信设备不在服务区内或者在弱覆盖区域内; 另一无线通信 设备所在网络繁忙;诸如寻呼指示块资源等的参数设置不合理、上行信道 功率不足等等。
[65]在判断装置 14判断寻呼失败的情况下,确定装置 15可以 4艮据判断装 置 14的判断结果, 确定不在无线通信设备 4与另一无线通信设备之间建 立设备到设备通信。
[66]寻呼装置 13用于发起寻呼的物理上行链路控制信道( PUCCH )中包 括用于确定该寻呼是否为设备到设备寻呼的寻呼模块;所述物理上行链路 控制信道由另一无线通信设备接收并解调,以获得与所述无线通信设备发 起的所述寻呼对应的寻呼消息。
[67]根据本公开的一个实施例, 在作为发起通信的无线通信设备 4 的 PUCCH中嵌入了 D2D— Paging寻呼模块, 作为通信目标的另一无线通信 设备接收并能够解调无线通信设备 4发送的 PUCCH, 以获取其中的寻呼 消息。
[68] 图 5a和图 5b分别示出了作为发起通信的无线通信设备 4发送寻呼信 令的格式以及作为目标设备的另一无线通信设备对接收到的寻呼信令的 响应的信令格式。
[69]如图 5a和图 5b所示, 由于 PUCCH承载上行控制信息(UCI ), 因 此不与 PUSCH同时传输, 处于上行带宽的边缘。发起设备一直以广播方 式发送 PUCCH, 目标设备监听 PUCCH, 寻呼模块存在于 PUCCH中的 特定时刻, 称为 D2D寻呼时机 (D2D PO ,D2D— Paging— Occasion), 决定 PO相关的两个参数是 T和 nB, 其由系统 SIB2通知 UE。
[70]根据 PO 相关计算出的具体位置后, 目标设备监听相应的子帧中 PUCCH。 目标设备一直监听收到的 PUCCH, 在该 PUCCH的寻呼时机 PO中, 如果解调出 D2D寻呼模块, 则将其与目标设备的 ID进行比对, 如果该 D2D寻呼模块携带的 UE ID(IMSI或者 S-TMSI)与自身 UE ID匹 配, 则向发起设备发送寻呼确认信令。 如图 5b 所示, 寻呼确认 D2D— Paging— Response 模 块 在 PUCCH 中 PRO ( Paging_Response_Occasion )时机传输, 寻呼确认模块包括寻呼响应模 块, 其表示接收到 D2D寻呼。
[71] 与传统的寻呼块相比,由于在 PUCCH中嵌入了 D2D— Paging寻呼模 块,从而实现了在不对传统的寻呼块进行 4艮大改动的情况下, 实现通过帧 结构判定是否为 D2D寻呼。
[72]根据本公开的一个实施例,还提供一种在首次寻呼失败之后,通过改 变寻呼参数继续进行寻呼的无线通信设备。 具体地, 在此情况下, 寻呼装 置 13还配置为在确定无线通信设备 4的寻呼失败的情况下, 通过扩展无 线通信设备的寻呼范围和 /或利用服务该无线通信设备 4的基站辅助继续 进行寻呼; 并且确定装置 15进一步配置为基于继续寻呼的结果, 对无线 通信设备与该另一无线通信设备之间的设备到设备通信的建立进行确定。 在此情况下, 判断装置 14与上述描述的首次寻呼类似地对寻呼结果进行 判断,并且确定装置 15基于判断装置 14判断的寻呼结果,对无线通信设 备与所述另一无线通信设备之间的设备到设备通信的建立进行确定。
[73]根据本公开的一个实施例, 寻呼装置 13被配置为根据该无线通信设 备 1和另一无线通信设备的位置区的信息,将寻呼范围从该无线通信设备 所在的位置区扩展到其的最大功率所覆盖的所有位置区,或者改变寻呼频 段, 来继续进行寻呼。 例如, 当作为目标设备的另一无线通信设备例如由 于移动到另外的位置区而寻呼失败时,由服务该另一无线通信设备的基站 将该另一无线用户的、经干扰协调后发生变化的频段通知作为发起设备的 无线通信设备,使其改变寻呼频段,对该另一无线通信设备继续进行寻呼。
[74] 更具体地, 根据本公开的优选实施例, 可以釆用三次寻呼的方式: 根 据该无线通信设备的位置区信息在该位置区进行首次寻呼;在首次寻呼失 败的情况下,将寻呼范围从该无线通信设备所在的位置区扩展到该无线通 信设备的最大功率所覆盖的所有位置区,进行再次寻呼,并且还可以利用 精准的 GPRS定位寻呼; 并且在再次寻呼失败的情况下, 开始第三次寻 呼, 第三次寻呼加入服务作为发起设备的无线通信设备的基站的辅助,通 过该基站发送的另一无线通信设备的、 变化的载波频段进行第三次寻呼。 通常,在三次寻呼失败之后, 由于寻呼时长的不断增大会导致无线通信设 备的早释, 从而导致寻呼消息丢失, 因此可以将三次寻呼定为 D2D寻呼 的上限。但是本公开不限于此, 本领域技术人员可以理解, 也可以根据需 要设定一次、 两次、 四次等作为 D2D寻呼上限。 [75]在判断装置 14判断第三次寻呼失败的情况下,确定装置 15确定不在 无线通信设备 4与另一无线通信设备之间建立设备到设备通信。
[76] 另一方面, 根据本公开的一个实施例, 在判断装置 14判断寻呼装置 的寻呼成功的情况下, 确定装置 15可以才艮据所述另一无线通信设备对于 所述无线通信设备发送的寻呼的测量结果,对所述无线通信设备与所述另 一无线通信设备之间的设备到设备通信的建立进行确定。
[77]具体地,由作为通信目标的另一无线通信设备在接收到发起通信的无 线通信设备 4的寻呼的情况下对无线通信设备 4发送的寻呼信令的质量 (例如信号的功率等等)进行测量,并将测量结果上报到无线通信设备 4, 由无线通信设备 4根据该测量结果确定是否在无线通信设备 4与另一无线 通信设备之间建立 D2D通信。
[78]例如,当测量结果显示无线通信设备 4与另一无线通信设备之间通信 链路的通信质量较差时,则无线通信设备 4确定不能在其与另一无线通信 设备之间建立 D2D通信。 在此情况下, 无线通信设备 4通过基站与另一 无线通信设备进行通信。又例如, 当测量结果显示无线通信设备 4与另一 无线通信设备之间通信链路的通信质量能够进行 D2D通信, 则无线通信 设备 4确定能够与另一无线通信设备之间建立 D2D通信, 并开始与该另 一无线通信设备进行通信。
[79] 图 6 示意性地示出根据本公开实施例的无线通信设备的另一示例性 结构。
[80] 除了与图 4的无线通信设备 4类似地包括接收装置 11、寻呼装置 13、 判断装置 14、 确定装置 15之外, 图 6所示的无线通信设备 6还包括: 通 信装置 17, 用于在确定在无线通信设备 6与另一无线通信设备之间建立 设备到设备通信的情况下,使得无线通信设备 ό与另一无线通信设备在专 用载波上以复用资源的方式进行设备到设备通信。
[81]具体地, 当确定装置 15确定了在无线通信设备 6与另一无线通信设 备之间建立设备到设备通信, 通信装置 17使得无线通信设备 6与另一无 线通信设备直接在为进行 D2D通信而设置的专用载波上以复用资源的方 式进行设备到设备通信。
[82] 由于在寻呼成功之后,可以直接在发送到无线通信设备 6和另一无线 通信设备的寻呼信令所指示的专用载波上开始 D2D通信, 因此避免了无 线通信设备与基站关于资源分配的其他信令的占用。 [83]此外, 根据本公开实施例的无线通信设备还提供在进行 D2D通信时 的链路监测的功能, 从而在链路受损时在 D2D通信的无线通信设备之间 启动包括传统链路和 D2D通信链路的双连接链路。
[84] 图 7是示意性地示出根据本公开实施例的无线通信设备的再一示例 性结构。
[85] 除了与图 6的无线通信设备 6类似地包括接收装置 11、寻呼装置 13、 判断装置 14、确定装置 15、通信装置 17之外, 图 7所示的无线通信设备 7还包括:链路监测装置 18,用于在无线通信设备 7与另一无线通信设备 建立了设备到设备通信的情况下,对接收到的信号进行评估, 以在出现以 下情况至少之一时, 确定用于设备到设备通信的链路受损:
( i )接收到的信号的功率低于第一阁值;
( ii )数据传输失败率高于第二阈值; 以及
( iii )数据重新传输的概率高于第三阈值。
[86]具体地, 进行 D2D通信的无线通信设备在 D2D通信过程中, 在接收 到对方发送的信号的同时,链路监测装置 18对用于 D2D通信的链路质量 进行评估, 信号的发送功率可以根据所评估的链路的情况进行动态自适 应,如果接收到的信号的功率值低于第一阈值、数据传输失败率高于第二 阈值或者数据重新传输概率高于第三阈值, 则链路监测装置 18确定用于 D2D通信的链路受损, 并向自身的服务基站上报该情况。 在此情况下, 主服务基站在进行 D2D通信的无线通信设备之间建立传统的链路连接, 即无线通信设备之间通过基站建立通信。
[87]根据本公开的优选实施例, 在用于 D2D通信的链路受损时, 例如主 服务基站的基站除了在无线通信设备之间建立传统的链路连接之外,还通 知作为发起设备的无线通信设备继续对作为目标设备的另一无线通信设 备进行寻呼, 从而在 D2D通信的设备之间开启双连接链路。
[88]图 8 示意性地示出根据本公开实施例的无线通信设备的又一示例性 结构。
[89]除了与图 7的无线通信设备 7类似地包括接收装置 11、寻呼装置 13、 判断装置 14、 确定装置 15、 通信装置 17、 链路监测装置 18之外, 图 8 所示的无线通信设备 8还包括: 链路恢复装置 19, 用于在确定用于设备 到设备通信的链路受损的情况下,发送建立通过基站进行的所述无线通信 设备与另一无线通信设备的通信连接的请求, 并且通知寻呼装置 13向另 一无线通信设备发起寻呼, 其中, 在寻呼装置 13寻呼成功的情况下, 链 路恢复装置 13用于恢复所述无线通信设备与所述另一无线通信设备之间 的设备到设备通信。
[90]图 9示出了在 D2D通信链路受损后在进行 D2D通信的通信设备之间 建立双连接链路的一种示例。
[91]如图 9所示, 双连接链路包括: 无线通信设备到基站的数据信道连接 —―数据平面连接,其为传统低频链路连接, 以保证无线通信设备之间的 通话 QoS需求;无线通信设备到无线通信设备的 D2D— Paging信道( D2D 寻呼信道)连接一一控制平面连接,其为 D2D高频链路连接,以进行 D2D 寻呼来恢复 D2D通信链路连接。
[92]在无线通信设备 901对作为目标设备的另一无线通信设备 902寻呼成 功的情况下,由链路恢复装置恢复 D2D通信链路,并且无线通信设备 901 与该另一无线通信设备 902释放与基站 903的 U平面连接,而转移到 D2D 专用频段的 U平面连接。 根据本公开的优选实施例, 可以为寻呼设置寻 呼次数限制,例如如果三次寻呼都不成功, 则可以确定作为发起设备的无 线通信设备 901与另一无线通信设备 902之间不能建立 D2D通信, 从而 它们之间通过基站进行传统的通信。
[93]根据本公开的实施例, 上述双连接链路可以在载波聚合的辅助下进 行, 无线通信设备的低频数据信道载波和高频控制信道载波通过载波聚 合, 工作在此方式可以保证数据信道和控制信道的独立运作。
[94]在此情况下, 由于无线通信设备之间的载波不占用数据信道, 只占用 控制信道, 因此该载波可以为新载波模式(NCT ); 无线通信设备到基站 的载波只占用数据信道, 因此该载波也可以为新载波模式。新载波模式的 控制信道载波 C— NCT和新载波模式的数据信道载波 U— NCT可以聚合传 输, 或者分别于其他载波聚合传输, 或者在 Stand— along (独立)的情况 下独立传输。
[95]以上结合图 3-图 9描述了在图 1的无线通信设备 1作为发起通信的发 起设备的具体结构,但是无线通信设备 1也可以对应于作为通信目标的目 标设备。
[96]回到图 1, 在无线通信设备 1作为目标通信设备的情况下, 无线通信 设备 1还配置为提前一个预定时间段来监听寻呼,以使另一无线通信设备 寻呼与无线通信设备 1接收寻呼同步。
[97]在 TDD系统中, 无线通信设备的接收和发送在同一频率载波的不同 时隙, 以保证以时间区分接收信道和发送信道。 此时, 发起设备与目标设 备仍保持与基站同步, 由于发起设备和目标设备的》 L需要同步, 因此将 目标设备配置为自动调整下行对其位置。
[98]具体地, 由于在 TDD系统中, 子帧 0和 5传输的总是下行子帧, 子 帧 1传输的总是特殊子帧,则目标设备可以推迟 2-4个传输时间间隔( TTI ) 或者提前 3个传输时间间隔监听寻呼,从而使 ^设备发起寻呼与接收设 备接收寻呼同步。
[99]根据本公开的实施例,在作为发起设备的无线通信设备的物理上行链 路控制信道包括寻呼模块的情况下,作为目标设备的无线通信设备可以釆 用直接监听 PUCCH中的寻呼模块的方式监听寻呼。
[100] 根据本公开的一个实施例, 还提供一种无线通信方法, 用于设备到 设备通信。 下面结合图 10来描述无线通信方法的一种示例性处理。
[101] 如图 10所示,根据本公开的实施例的无线通信方法的处理流程 900 开始于 S1010, 然后执行 S1020的处理。
[102] 在 S1020中, 当发起通信的发起设备与作为通信目标的目标设备之 间满足设备到设备通信的预定条件时,分别向发起设备和目标设备发送寻 呼信令, 寻呼信令用于辅助发起设备和目标设备之间的寻呼。 例如, 可以 通过例如基站或者核心网执行步骤 S1020。对于通信设备之间是否满足设 备到设备通信的预定条件以及寻呼信令的发送可以参考例如结合图 1-2对 无线通信系统和寻呼信令的描述,在此省略其详细描述。然后执行 S1030。
[103] 在 S1030, 根据发起设备基于寻呼信令对所述目标设备进行寻呼的 结果, 对发起设备与目标设备之间的设备到设备通信的建立进行确定。

[110] 在 S1032, 根据所述目标设备是否在第一预定时间段内接收到所述 发起设备的寻呼或者所述发起设备是否在第二预定时间段内接收到所述 目标设备对于所述发起设备发送的寻呼的确认,来判断所述发起设备的寻 呼是否成功。 根据本公开实施例的无线通信方法中, S1032例如可以通过 执行例如参照图 4-8描述的判断装置 14的处理来实现,在此省略其描述。 然后执行 S1033。
[111] 在 S1032, 可以根据目标设备是否在第一预定时间段内接收到发起 设备的寻呼或者发起设备是否在第二预定时间段内接收到目标设备对于 ^设备发送的寻呼的确认,来判断发起设备的寻呼是否成功;更具体地, 如果所述目标设备在所述第一预定时间段内接收到所述发起设备的寻呼 或者如果所述发送设备在第二预定时间段内接收到所述目标设备的确认, 则判断所述发起设备的寻呼成功;以及如果所述目标设备在所述第一预定 时间段内未接收到所述发起设备的寻呼, 则判断所述发起设备的寻呼失 败。
[112] 在 S1033, 根据发起设备的寻呼是否成功, 对发起设备与目标设备 之间的设备到设备通信的建立进行确定,并且在由于发起设备的寻呼成功 而确定在发起设备与目标设备之间建立 D2D通信的情况下, 执行 S1034; 否则, 在发起设备的寻呼失败的情况下, 执行 S1035。
[113] 根据本公开实施例, 在 S1033, 例如, 在发起设备的寻呼成功的情 况下,可以进一步根据目标设备对于发起设备发送的寻呼的测量结果,对 ^设备与所述目标设备之间的设备到设备通信的建立进行确定。
[114] 在 S1034, 发起设备与目标设备在所述专用载波上以复用资源方式 进行设备到设备通信。
[115] 在 S1035, 发起设备与目标设备进行传统方式的通信, 即通过基站 进行通信。
[116] 根据本公开的实施例, 在 S1031, 发起设备利用包括用于确定寻呼 是否为设备到设备寻呼的寻呼模块的物理上行链路控制信道进行寻呼; 目 标设备接收并解调发起设备的物理上行链路控制信道,以获得发起设备发 送的寻呼消息。
[117] 根据本公开的一个实施例, 在 S1033, 在发起设备的寻呼成功的情 况下,根据目标设备对于发起设备发送的寻呼的测量结果,对发起设备与 目标设备之间的设备到设备通信的建立进行确定。
[118] 根据本公开的一个实施例, 目标设备提前第三预定时间段来监听寻 呼, 以使发起设备发送寻呼与目标设备接收寻呼同步。
[119] 根据本公开的一个实施例, 在 S1032还包括: 在判断寻呼失败的情 况下, 还可以通过扩展所述发起设备的寻呼范围和 /或利用服务所述发起 设备的基站辅助继续进行寻呼,并基于继续寻呼的结果,对所述发起设备 与所述目标设备之间的设备到设备通信的建立进行确定。
[120] 根据本公开的优选实施例, 可以通过将寻呼范围从该发起设备所在 的位置区扩展到所述发起设备的最大功率所覆盖的所有位置区或者改变 寻呼频段, 继续进行寻呼。

( i )所述发起设备或者所述目标设备接收到的信号的功率低于第 一阈值;
( ii )数据传输失败率高于第二阈值; 以及
( iii )数据重新传输的概率高于第三阈值。 [122] 根据本公开实施例的无线通信方法还包括在确定用于设备到设备 通信的链路受损后, 建立通过基站进行的发起设备与目标设备的通信连 接, 并且由发起设备向目标设备^寻呼, 其中, 在发起设备向目标设备 ^^的寻呼成功的情况下,恢复发起设备与目标设备之间的设备到设备通 信。
[123] 根据本公开的实施例,可以通过载波聚合实现包括通过基站进行的 通信连接和发起设备与目标设备之间的设备到设备连接的双链路连接。
[124] 此外, 根据本公开实施例的无线通信方法还包括: 利用发起设备和 目标设备的位置区信息,确定所述发起设备与所述目标设备是否满足设备 到设备通信的预定条件。
[125] 根据 开的实施例, 还提供一种基站。 接下来, 参照图 12的框 图说明根据本发明实施例的基站的配置示例。该基站例如包括:宏蜂窝基 站、 微蜂窝基站、 微微蜂窝基站、 中继节点或家庭基站, 但不限于此。
[126] 根据本发明实施例的基站 1200包括: 条件确定装置 1201, 用于确 定要进行通信的通信设备是否满足设备到设备通信的预定条件;以及寻呼 信令发送装置 1202, 用于在确定满足所述预定条件的情况下, 向所述通 信设备发送寻呼信令,该寻呼信令用于辅助所述通信设备之间的寻呼,其 中,该寻呼信令用于对所述通信设备之间的设备到设备通信的建立进行确 定。
[127] 根据本公开的优选实施例, 条件确定装置 1201被配置为利用发起 设备和目标设备的位置区信息,确定发起设备与目标设备是否满足设备到 设备通信的预定条件。 根据本公开始实施例的基站 1200例如可以是参照 图 2描述的基站 203。 基站 1200向通信设备所发送例如包含用 P-RNTI 加扰的 DCI 1C的 PDCCH以传送所述寻呼信令, 以及通过该 DCI 1C指 示的 PDSCH发送寻呼消息, 等等, 具体寻呼信令和寻呼消息的格式和内 容可以参考上述图 2中的描述。
[128] 与现有技术相比, 根据本公开实施例的无线通信设备、 无线通信方 法、和基站至少能够实现以下有益效果: 由于基站向无线通信设备下发的 寻呼信令能够辅助无线通信设备之间的 D2D寻呼, 因此能够提高无线通 信设备的寻呼效率从而提高 D2D通信的效率。
[129] 上述装置中各个组成模块、 单元可通过软件、 固件、 硬件或其组合 的方式进行配置。 配置可使用的具体手段或方式为本领域技术人员所熟 知, 在此不再赘述。 在通过软件或固件实现的情况下, 从存储介质或网络 向具有专用硬件结构的计算机安装构成该软件的程序,该计算机在安装有 各种程序时, 能够执行各种功能等。
