步骤S102,当检测结果为是时,执行所述第一操作。
也就是说,终端设备在采用本发明所述方法后,只有在检测到网络侧的触发操作,才执行第一操作,从而提高了下行控制信息或信号的调度灵活性,以及提高了资源利用效率。
为使本发明的目的、技术方案和优点更加清楚明白,下文中将结合附图对本发明的实施例进行详细说明。需要说明的是,在不冲突的情况下,本实施例中的特征可以相互任意组合。
本发明实施例中,步骤S101中,检测网络侧是否按设定方式触发了所述终端设备执行第一操作的实现方式包括以下方式中的至少一种:
方式一:检测网络侧是否通过数据包触发了所述终端设备执行第一操作;
在本发明的一个具体实施例中,该方式的具体实施过程为:检测网络侧是否调度了数据包(等价于检测网络侧是否发送了用于给终端设备的数 据包传输授予资源的下行控制信息,若是,则说明网络侧调度了数据包),若是,则判定网络侧触发了所述终端设备执行第一操作。
方式二:检测网络侧是否通过分配给数据包的子帧数触发了所述终端设备执行第一操作;
在本发明的一个具体实施例中,该方式的具体实施过程为:检测网络侧分配给数据包的子帧数是否达到了设定的门限,若是,则判定网络侧触发了所述终端设备执行第一操作;
方式三:检测网络侧是否通过下行控制信息格式触发了所述终端设备执行第一操作;
在本发明的一个具体实施例中,该方式的具体实施过程为:检测网络侧发送的用于资源授予的下行控制信息的格式是否为指定格式,若是,则判定网络侧触发了所述终端设备执行第一操作。
例如,检测网络侧发送的用于资源授予的下行控制信息的格式是否是6-0B,若是,则触发终端设备执行第一操作;或者,检测网络侧发送的用于资源授予的下行控制信息的格式是否是6-1B,若是,则触发终端设备执行第一操作;或者,检测网络侧发送的用于资源授予的下行控制信息的格式是否是6-0B和6-1B中的一个,若是,则触发终端设备执行第一操作。
方式四,检测网络侧是否通过下行控制信息信令触发了所述终端设备执行第一操作;
在本发明的一个具体实施例中,该方式的具体实施过程为:检测网络侧发送的用于资源授予的下行控制信息中的信令是否指示了终端设备执行第一操作,若是,则判定网络侧触发了所述终端设备执行第一操作。
例如,检测网络侧发送的用于资源授予的下行控制信息中的信令是否取值为1,若是,则判定网络侧触发了终端设备执行第一操作。
方式五,检测网络侧是否通过数据包的传输模式触发了所述终端设备 执行第一操作;
在本发明的一个具体实施例中,该方式的具体实施过程为:检测网络侧设置的数据包的传输模式是否为指定传输模式,若是,则判定网络侧触发了所述终端设备执行第一操作;
例如,检测网络侧数据包的传输模式是否是空间复用,若是,则判定网络侧触发了终端设备执行第一操作;或者,检测网络侧数据包的传输模式是否是空间分集,若是,则判定网络侧触发了终端设备执行第一操作。
方式六,检测网络侧是否通过信号触发了所述终端设备执行第一操作;
在本发明的一个具体实施例中,该方式的具体实施过程为:检测网络侧是否在指定的时频资源下发了指定序列的第二信号,若是,则判定网络侧触发了所述终端设备执行第一操作。
其中,第二信号采用的序列是预设的或者通过信令确定的;第二信号占用的时频资源是预设的或者通过信令确定的。
方式七,检测网络侧是否通过数据包的类型触发了所述终端设备执行第一操作;
在本发明的一个具体实施例中,该方式的具体实施过程为:检测网络侧调度的数据包是否为指定类型的数据包,若是,则判定网络侧触发了所述终端设备执行第一操作;
例如,检测网络侧传输的数据包的类型是否是用于确认无线资源控制RRC连接释放消息接收的数据包,若是,则判定网络侧触发了终端设备执行第一操作。
方式八,检测网络侧是否通过子帧的长度(等价于持续时间)触发了所述终端设备执行第一操作。
在本发明的一个具体实施例中,设想系统中存在两种长度的子帧(即 正常子帧和短子帧),该方式的具体实施过程为:检测网络侧是否进行了短子帧的调度,若是,则判定网络侧触发了所述终端设备执行第一操作;短子帧的调度等价于在短子帧上调度了数据包的传输。
在本发明的可选实施例中,当所述第一操作是在搜索空间接收下行控制信息时,所述下行控制信息包括以下至少之一:
用于资源授予的下行控制信息;
用于功率控制的下行控制信息;
用于肯定确认ACK反馈的下行控制信息;
用于否定的确认NACK反馈的下行控制信息。
其中,用于资源授予的下行控制信息包括以下至少之一:用于为新数据包授予资源的下行控制信息,用于为数据包的重传授予资源的下行控制信息。
其中,用于为新数据包授予资源的下行控制信息除用于实现为新数据包授予资源的功能以外,还用于实现针对前一个使用相同混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)进程的数据包的ACK反馈功能。例如,以上行数据包为例,设想存在两个数据包(表示为第一数据包和第二数据包),第一数据包首先被终端设备发送并且被网络侧解码成功,然后,用于为第二数据包授予资源的下行控制信息被网络侧发送,其中,该下行控制信息中指示的HARQ进程与第一数据包使用的HARQ进程相同;当终端设备接收到用于为第二数据包授予资源的下行控制信息时,终端设备除获取到为第二数据包授予的资源以外,还会认为接收到了针对第一数据包的ACK反馈(等价于第一数据包被解码成功)。
其中,用于ACK反馈和/或NACK反馈的下行控制信息包括以下至少之一:公共的下行控制信息、终端设备专有的下行控制信息。
其中,一个公共的下行控制信息承载多个终端设备的反馈;一个终端 设备专有的下行控制信息承载唯一终端设备的反馈;该反馈为所述ACK反馈或者所述NACK反馈。
其中,用于ACK反馈的所述终端设备专有的下行控制信息包括以下特征:
所述终端设备专有的下行控制信息的有效载荷全部为“1”;例如如果有效载荷包括16个比特,则16个比特取值全部为“1”。在这种情况下,当终端设备检测到了该有效载荷全部为“1”的终端设备专有的下行控制信息时,终端设备视为是接收到了ACK反馈。
其中,用于NACK反馈的所述终端设备专有的下行控制信息包括以下特征:
所述终端设备专有的下行控制信息的有效载荷全部为“1”;例如如果有效载荷包括16个比特,则16个比特取值全部为“1”。在这种情况下,当终端设备检测到了该有效载荷全部为“1”的终端设备专有的下行控制信息时,终端设备视为是接收到了NACK反馈。
在本发明可选的实施例中,根据以下之一确定所述公共的下行控制信息可用的控制信道单元集:
(1)可用的控制信道单元集是预设的,例如预设可用的控制信道单元集只存在1个且该控制信道单元集包括搜索空间中的所有控制信道单元;
(2)通过信令确定可用的控制信道单元集;
其中,可用的控制信道单元集存在至少一个。
在本发明可选的实施例中,通过以下之一确定所述ACK反馈和/或NACK反馈在所述公共的下行控制信息中的位置(即确定所述ACK反馈和/或NACK反馈对应所述公共的下行控制信息中的哪一个比特):
(1)通过信令确定;
(2)根据分配给所述数据包的频域资源确定;所述频域资源包括以下 至少之一:资源块和窄带。
例如以频域资源是窄带为例,设想可分配给数据包的窄带(即可用于数据包传输的窄带)的数目是16个以及公共下行控制信息包括16个比特,此时,使可以分配给数据包的16个窄带与公共下行控制信息的16个比特位置一一对应即可;以频域资源是窄带和资源块为例,设想可分配给数据包的窄带(即可用于数据包传输的窄带)的数目是8个,每一个窄带中可分配给数据包的资源块集合包括2类,以及公共的下行控制信息包括16个比特,此时第1个窄带中的第1类和第2类资源块集合分别对应所述16个比特位置中的第1个和第2个比特,以此类推,第8个窄带中的第1类和第2类资源块集合分别对应所述16个比特位置中第15个和第16个比特。
其中,用于所述公共的下行控制信息循环冗余校验(Cyclic Redun-dancy Check,简称CRC)加扰的射频网络临时标识(Radio Network Temporal Identity,简称RNTI)是预设的或者是通过信令确定的。
本发明实施例中,当所述第一操作是在搜索空间接收下行控制信息时,所述的搜索空间包括以下至少之一:第一搜索空间、第二搜索空间、第三搜索空间;
其中,所述第一搜索空间是终端设备专有搜索空间(UE-specific Search Space,简称USS),该终端设备专有搜索空间是触发在搜索空间接收下行控制信息之前已有的搜索空间;
所述第二搜索空间是所述终端设备专有搜索空间(即所述第一搜索空间)的子集;
所述第三搜索空间是(相对于触发在搜索空间接收下行控制信息之前已有的搜索空间)新增加的终端设备专有搜索空间或者新增加的公有搜索空间。
需要说明的是,所谓终端设备专有搜索空间意味着在该搜索空间中接 收的下行控制信息都是终端设备专有的下行控制信息,所谓公有搜索空间意味着在该搜索空间中接收的下行控制信息包括公共的下行控制信息(所谓公共的下行控制信息意味着该下行控制信息包含发送给多个终端设备的信息)。.
本发明实施例中,所述第二搜索空间和/或所述第三搜索空间,位于数据包的传输期间;即所述第二搜索空间和/或所述第三搜索空间的时域位置位于从分配给数据包的第一个子帧的起始时刻开始到分配给数据包的最后一个子帧的结束时刻为止这一时间范围内。在所述下行控制信息为用于ACK反馈的下行控制信息时,通过该方法,在上行数据包按照为该数据包分配的子帧数发送结束之前ACK反馈就能够被接收,从而终端设备能够提前终止该数据包的发送,最终减少了不必要的资源损耗和终端设备的功率损耗。
本发明实施例中,当所述第二搜索空间和/或所述第三搜索空间位于数据包的传输期间时,作为一种优选实施方式,所述第二搜索空间和/或所述第三搜索空间的时域位置位于分配给数据包的第K1个子帧之后和倒数第K2个子帧之前;其中,所述K1和K2是大于1的整数。例如,在下行控制信息为用于ACK反馈的下行控制信息时,在网络侧设备还没有完成数据包解码时,终端设备不需要监控ACK反馈;即该方法考虑了网络侧设备解码数据包的时延。
本发明实施例中,确定所述第三搜索空间的时域位置的方式包括:
方式一,通过信令确定所述第三搜索空间的时域位置;例如通过信令直接获取第三搜索空间时域位置的起始子帧;
方式二,通过分配给数据包的最后1个子帧(即数据包发送的结束子帧)确定第三搜索空间的时域位置;例如,所述第三搜索空间的时域位置开始于数据包发送结束之后的第Q1个子帧,所述Q1是大于1的整数;
在本发明实施例的一个具体示例中:设想数据包为上行数据包;
在本示例中,根据分配给数据包的最后1个子帧(即数据包发送的结束子帧)确定第三搜索空间的时域位置;具体地,第三搜索空间的时域位置开始于数据包发送结束后的第4个子帧;如图2中框格所示。
方式三,通过信令确定所述第三搜索空间候选时域位置;根据所述候选时域位置和分配给数据包的最后1个子帧(即数据包发送的结束子帧)确定所述第三搜索空间的时域位置;例如,第三搜索空间的时域位置是在所有候选的时域位置中开始于数据包发送的结束子帧后第Q2个子帧之后的第一个出现的时域位置,或者,第三搜索空间的时域位置是在所有候选时域位置中开始于数据包发送的结束子帧后第Q2个子帧之后的第一个出现的与数据包的HARQ进程相对应的时域位置,或者,第三搜索空间的时域位置是在所有候选时域位置中开始于数据包发送的结束子帧后第Q2个子帧之后的最先出现的连续Q3个时域位置,所述Q2是大于1整数,所述Q3是大于1整数。
其中,通过信令确定所述第三搜索空间候选时域位置,包括以下之一:
通过信令确定所述第三搜索空间候选时域位置的起始子帧和大小;
通过信令确定所述第三搜索空间候选时域位置的起始子帧;采用预设的所述第三搜索空间候选时域位置的大小,例如预设所述第三搜索空间候选时域位置的大小等于第一搜索空间(即终端设备专有搜索空间)时域位置的大小。
在本发明实施例的一个具体示例中:设想数据包为上行数据包;
在本示例中,网络侧设备(例如基站)通过信令指示候选时域位置;终端设备通过该信令即可获取该候选时域位置;其中,该候选时域位置周期性出现,如图3所示。
在本示例中,根据候选时域位置和分配给数据包的最后1个子帧确定第三搜索空间的时域位置;具体地,第三搜索空间的时域位置是在所有候选 的时域位置中开始于数据包发送的结束子帧后的第3个子帧之后的第一个出现的时域位置;设想n1是小于3的整数,n2是大于3的整数,则第三搜索空间的时域位置如图3所示。
在本发明实施例的又一个具体示例中:设想数据包为上行数据包;
在本示例中,网络侧设备(例如基站)通过信令指示候选时域位置;终端设备通过该信令即可获取该候选时域位置;其中,该候选时域位置周期性出现;如图4所示。
在本示例中,根据候选时域位置和分配给数据包的最后1个子帧确定第三搜索空间的时域位置;具体地,第三搜索空间的时域位置是在候选时域位置中开始于数据包发送的结束子帧后第3个子帧之后的第一个出现的与数据包的HARQ进程相对应的时域位置;
以4个HARQ进程为例,并设想当前数据包使用的HARQ进程是编号为3的HARQ进程;设想n1是大于3的整数;在这种情况下,第三搜索空间的时域位置如图4所示。在本示例中,一个候选时域位置对应的HARQ进程是根据该候选时域位置的起始子帧确定;具体地,每连续4个候选时域位置分别对应4类起始子帧(其中的第1个候选时域位置对应第1类起始子帧,类似的,第2个对应第2类起始子帧,第3个对应第3类起始子帧,第4个对应第1类起始子帧),该4类起始子帧依次对应4个HARQ进程(即编号为0、1、2和3的HARQ进程)。
在本发明实施例的又一个具体示例中:设想数据包为上行数据包;
在本示例中,网络侧设备(例如基站)通过信令指示候选时域位置;终端设备通过该信令即可获取该候选时域位置;其中,该候选时域位置周期性出现;如图5所示。
在本示例中,根据候选时域位置和分配给数据包的最后1个子帧(即数据包发送的结束子帧)确定第三搜索空间的时域位置;具体地,第三搜索 空间的时域位置是在候选时域位置中开始于数据包发送的结束子帧后第3个子帧之后的最先出现的连续3个时域位置;设想n1是大于3的整数,则第三搜索空间的时域位置,如图5所示。在本示例中,如果在第三搜索空间接收的下行控制信息是用于NACK反馈的公共下行控制信息,网络侧设备通过公共下行控制信息中新增加的信令指示该NACK反馈对应的HARQ进程,终端设备通过该信令确定该NACK反馈所对应的HARQ进程。
方式四,通过信令确定所述第三搜索空间的候选时域位置;根据所述候选时域位置和分配给数据包的子帧确定所述第三搜索空间的时域位置;
例如,第三搜索空间的时域位置是在所有候选的时域位置中开始于分配给数据包的第P1个子帧之后且结束于分配给数据包的倒数第P2个子帧之前的时域位置,所述P1和P2是大于1的整数;
其中,通过信令确定所述第三搜索空间候选时域位置,包括以下之一:
通过信令确定所述第三搜索空间候选时域位置的起始子帧和大小;
通过信令确定所述第三搜索空间候选时域位置的起始子帧;采用预设的所述第三搜索空间候选时域位置的大小,例如预设所述第三搜索空间候选时域位置的大小等于第一搜索空间(即终端设备专有搜索空间)时域位置的大小。
在本发明实施例的一个具体示例中:设想数据包为上行数据包;
在本示例中,网络侧设备(例如基站)通过信令指示候选时域位置;终端设备通过该信令即可获取该候选时域位置;其中,该候选时域位置周期性出现;如图6所示。
在本示例中,根据该候选时域位置和分配给数据包的子帧确定第三搜索空间的时域位置;具体地,第三搜索空间的时域位置是在所有候选的时域位置中开始于分配给数据包的第3个子帧之后,并且结束于分配给数据包的倒数第3个子帧之前的时域位置;设想n1和n4是大于3的整数,则第三搜 索空间最终的时域位置如图6所示。
方式五,根据分配给数据包的子帧数确定所述第三搜索空间的时域位置;
例如所述第三搜索空间的时域位置开始于分配给数据包的第x1*P3+1个子帧,其中,所述x1是等于1,2,…,X1-1的序列,所述X1是大于1整数,所述P3等于N/X1,所述N表示分配给数据包的子帧数;其中,所述X1取值为固定值或者是根据分配给数据包的子帧数(即N取值)确定的。
在本发明实施例的一个具体示例中:设想数据包为上行数据包;
在本示例中,第三搜索空间的时域位置(3个)分别开始于:
分配给数据包的第P+1个、第2P+1个和第3P+1个子帧;
其中P等于N/4,该N表示分配给数据包的子帧数;
如图7所示。
方式六,根据分配给数据包的子帧数和分配给所述第三搜索空间的子帧数确定所述第三搜索空间的时域位置;例如所述第三搜索空间的时域位置开始于分配给数据包的第x2*P4+1个子帧,所述x2是等于1,2,…,X2-1的序列,所述X2是大于1整数,所述P4等于N/X2,所述N表示分配给数据包的子帧数;其中,所述X2取值根据分配给数据包的子帧数(即N取值)和分配给所述第三搜索空间的子帧数(即第三搜索空间时域位置的大小)共同确定。
在本发明实施例的一个具体示例中,设想数据包为上行数据包;
在本示例中,根据分配给数据包的子帧数和分配给第三搜索空间的子帧数确定第三搜索空间的时域位置;设想分配给数据包的子帧数为N;
具体地,在分配给第三搜索空间的子帧数为M时,
第三搜索空间的时域位置包括3个,分别开始于分配给数据包的第P+1个、第2P+1个和第3P+1个子帧;P等于N/4;如图8(a)所示;
在分配给第三搜索空间的子帧数为2M时,第三搜索空间的时域位置包括1个且开始于分配给数据包的第Q+1个子帧;其中Q等于N/2;如图8(b)所示。
方式七,将所述第一搜索空间的时域位置作为所述第三搜索空间的候选时域位置;根据所述候选时域位置和分配给数据包的最后1个子帧(即数据包发送的结束子帧)确定所述第三搜索空间的时域位置;该方式类似于方式三,两者的区别只是确定第三搜索空间候选时域位置的方式不同,具体示例可参考方式三的示例描述。
方式八,将所述第一搜索空间的时域位置作为所述第三搜索空间候选时域位置;根据所述候选时域位置和分配给数据包的子帧确定所述第三搜索空间的时域位置;该方式类似于方式四,两者的区别只是确定第三搜索空间候选时域位置的方式不同,具体示例可参考方式四的示例描述。
需要说明的是,本发明实施例中,所述第三搜索空间时域位置的大小等价于分配给第三搜索空间的子帧数;如果没有特别指出,通过以下之一确定所述第三搜索空间时域位置的大小:
通过信令确定所述第三搜索空间时域位置的大小;
采用预设的所述第三搜索空间时域位置的大小,例如预设所述第三搜索空间候选时域位置的大小等于第一搜索空间(即终端设备专有搜索空间)时域位置的大小。
在本发明可选的实施例中,确定所述第三搜索空间的窄带的方式包括:
方式一,通过信令确定所述第三搜索空间的窄带;
此时,作为一种选择,可以通过信令进一步确定所述第三搜索空间在所述窄带中占用的资源块集合;
方式二,根据所述第一搜索空间的窄带确定所述第三搜索空间的窄带。
其中,所述第三搜索空间的窄带对应第三搜索空间的频域位置,具体 是第三搜索空间在频域上所在的窄带。
进一步的,所述根据第一搜索空间的窄带确定第三搜索空间的窄带,包括:所述第三搜索空间的窄带与所述第一搜索空间的窄带相同。此时,作为一种选择,所述第三搜索空间在所述窄带中占用的资源块集合与所述第一搜索空间在所述窄带中占用的资源块集合相同。
本发明实施例中,在所述第三搜索空间与所述第一搜索空间(即终端设备专有搜索空间)存在冲突时,放弃在所述第三搜索空间接收所述下行控制信息;即在终端设备专有搜索空间接收下行控制信息的优先级更高。
本发明实施例中,确定所述第二搜索空间的时域位置的方式包括:
方式一,通过信令确定所述第二搜索空间的时域位置;例如通过信令直接获取第一搜索空间(触发前已有的终端设备专有搜索空间)中的哪些搜索空间是第二搜索空间。
方式二,根据第一搜索空间的时域位置和分配给数据包的最后1个子帧(即数据包发送的结束子帧)确定所述第二搜索空间的时域位置;例如,第二搜索空间的时域位置是在所有第一搜索空间的时域位置中开始于数据包发送的结束子帧后第D1个子帧之后的第一个出现的时域位置,或者,第二搜索空间的时域位置是在所有第一搜索空间的时域位置中开始于数据包发送的结束子帧后第D1个子帧之后的第一个出现的与数据包的HARQ进程相对应的时域位置,或者,第二搜索空间的时域位置是在所有第一搜索空间的时域位置中开始于数据包发送的结束子帧后第D1个子帧之后的最先出现的连续D2个时域位置,所述D1是大于1整数,所述D2是大于1整数。
方式三,根据第一搜索空间的时域位置和分配给数据包的子帧确定所述第二搜索空间的时域位置;例如,第二搜索空间的时域位置是在所有第一搜索空间的时域位置中开始于分配给数据包的第D3个子帧之后且结束于分配给数据包的倒数第D4个子帧之前的时域位置,所述D3和D4是大于1的 整数。
本发明实施例中,对于半双工(Half Duplex,简称HD)频分双工(Frequency Division Duplex,简称FDD)系统,所述第二搜索空间和/或第三搜索空间位于终端设备的上行间隙内(在所述搜索空间包括所述第二搜索空间和第三搜索空间至少之一时);即所述第二搜索空间和/或第三搜索空间的时域位置位于从上行间隙的第一个子帧的起始时刻开始到上行间隙的最后一个子帧的结束时刻为止这一时间范围内。需要说明的是,所述终端设备的上行间隙是在终端设备发送上行数据包期间定义的用于指定用途的发送间隙;在除发送上行数据包期间以外的其它时间段中定义间隙是没有任何意义的。例如,在下行控制信息为用于ACK反馈下行控制信息时,由于处于HD-FDD模式的终端设备在发送上行数据包的同时无法接收下行数据,所以只能在发送数据包期间引入上行间隙用以实现接收下行控制信息的目的。
其中,所述上行间隙为第一上行间隙或第二上行间隙;所述第一上行间隙是终端设备用于下行时频同步的上行间隙,该上行间隙是触发在搜索空间接收下行控制信息之前已有的上行间隙;所述第二上行间隙是(相对于触发前已有的上行间隙,例如第一上行间隙)新增加的上行间隙。需要说明的是,在所述上行间隙为第一上行间隙时,所述第一上行间隙除用于终端设备下行时频同步以外还用于终端设备接收反馈;在所述上行间隙为第二上行间隙时,所述第二上行间隙只用于终端设备接收反馈。
根据以下方式之一确定所述第二上行间隙的时域位置:
方式一,通过信令确定所述第二上行间隙的时域位置;例如通过信令直接获取第二上行间隙时域位置的起始子帧;
方式二,所述第二上行间隙的时域位置开始于所述第一上行间隙之后的第1个子帧(即所述第二上行间隙紧靠所述第一上行间隙);
方式三,通过信令确定所述第二上行间隙的候选时域位置;根据所述第二上行间隙的候选时域位置和分配给所述数据包的子帧确定所述第二上行间隙的时域位置;例如所述第二上行间隙的时域位置是在所有候选时域位置中开始于分配给数据包的第M1个子帧之后,并且结束于分配给数据包的倒数第M2个子帧之前的时域位置,其中,该M1和M2个是大于3的整数;
其中,通过信令确定所述第二上行间隙候选时域位置,包括以下之一:
通过信令确定所述第二上行间隙候选时域位置的起始子帧和大小;
通过信令确定所述第二上行间隙候选时域位置的起始子帧;根据所述第二搜索空间或第三搜索空间时域位置的大小确定所述第二上行间隙候选时域位置的大小,例如所述第二上行间隙候选时域位置的大小等于所述第二搜索空间或第三搜索空间时域位置的大小加上固定整数(比如该固定整数可以为2)。
在本发明实施例的一个具体示例中:
该示例是对于HD-FDD系统,且设想数据包为上行数据包;
在本示例中,网络侧设备(例如基站)通过信令指示候选时域位置;终端设备通过该信令即可获取该候选时域位置;其中,该候选时域位置周期性出现;如图9所示。
在本示例中,根据该候选时域位置和分配给数据包的子帧确定第二上行间隙的时域位置;具体地,第二上行间隙的时域位置是在所有候选的时域位置中开始于分配给数据包的第3个子帧之后并且结束于分配给数据包的倒数第3个子帧之前的时域位置;设想n1是小于3整数及n4是大于3整数,则第二上行间隙的时域位置如图9所示。最终,在数据包的发送过程中,存在两个第二上行间隙;该两个第二上行间隙将数据包的发送过程分为3段,并且分配给每一段的子帧数分别是n1+n2+n3、n3和n4。
在图2-图9中所涉及的n1、n2、n3和n4代表的含义是子帧数量。
方式四,根据分配给所述数据包的子帧数确定所述第二上行间隙的时域位置;例如所述第二上行间隙的时域位置开始于分配给数据包的第y1*M3个子帧之后的第1个子帧,其中,所述y1是等于1,2,…,Y1-1的序列,所述Y1是大于1整数,所述M3等于N/Y1,所述N表示分配给数据包的子帧数;其中,所述Y1取值为固定值或者是根据分配给数据包的子帧数(即N取值)确定的;
在本发明实施例的一个具体示例中:
该示例是对于HD-FDD系统,且设想数据包为上行数据包;
在本示例中,根据分配给数据包的子帧数确定第二上行间隙时域位置;
具体地,第二上行间隙的时域位置(3个)分别开始于:分配给数据包的第P个、第2P个和第3P个子帧后的第1个子帧;其中P等于N/4,该N表示分配给数据包的子帧数;如图10所示。最终,在数据包的发送过程中,存在3个第二上行间隙;该3个第二上行间隙将数据包的发送过程分为4段且分配给每一段的子帧数是N/4。
方式五,根据分配给所述数据包的子帧数和分配给所述第二上行间隙的子帧数确定所述第二上行间隙的时域位置;例如所述第二上行间隙的时域位置开始于分配给数据包的第y2*M4个子帧之后的第1个子帧,所述y2是等于1,2,…,Y2-1的序列,所述Y2是大于1整数,所述M4等于N/Y2,所述N是分配给数据包的子帧数;其中,所述Y2取值根据分配给数据包的子帧数(即N取值)和分配给所述第二上行间隙时域位置的子帧数(即上行间隙时域位置的大小)共同确定。
需要说明的是,本发明实施例中,所述第二上行间隙时域位置的大小等价于分配给第二上行间隙的子帧数;如果没有特别指出,通过以下之一确定所述第二上行间隙时域位置的大小:
通过信令确定所述第二上行间隙时域位置的大小;
根据所述第二搜索空间或第三搜索空间时域位置的大小确定所述第二上行间隙时域位置的大小,例如所述第二上行间隙时域位置的大小等于所述第二搜索空间或第三搜索空间时域位置的大小加上固定整数(比如该固定整数可以为2)。
本发明实施例中,在所述第二上行间隙与所述第一上行间隙存在重叠时,放弃在所述第二上行间隙内的搜索空间接收下行控制信息,或者,推迟所述第二上行间隙。在采用推迟所述第二上行间隙的方式时,推迟后的所述第二上行间隙可以开始于所述第一上行间隙后的第1个子帧。
本发明实施例中,在所述上行间隙为第一上行间隙时,包括以下至少之一:
在所述搜索空间包括所述第三搜索空间时,所述第三搜索空间的窄带包含系统带宽中心的6个资源块(即第三搜索空间的窄带与传输同步信号和物理广播信道的窄带相同);用于接收同步信号和/或物理广播信道的子帧不用于接收所述下行控制信息(例如以用于接收物理广播信道的子帧不用于接收所述下行控制信息为例,设想在指定小区中,子帧#0和子帧#9用于接收物理广播信道,则子帧#0和子帧#9不用于接收所述下行控制信息)。终端设备的下行时频同步主要是基于同步信号和物理广播信道的接收;该方法有助于在接收下行控制信息的同时尽可能减少对同步信号和物理广播信道接收的影响。
本发明实施例中,当所述第一操作为在物理资源接收第一信号时,所述第一信号为以下之一:
用于下行时频同步的第一信号;
用于下行信道测量和信道估计的第一信号(即第一信号可以被视为下行的参考信号);
用于ACK反馈的第一信号;
用于NACK反馈的第一信号。
需要说明的是,当所述第一信号为用于ACK反馈的第一信号时,终端设备通过是否在所述物理资源上检测到第一信号来判断ACK反馈是否被发送;例如如果终端设备在所述物理资源上检测到第一信号,则判断ACK反馈被发送。类似地,当所述第一信号为用于NACK反馈的第一信号时,终端设备通过是否在所述物理资源上检测到第一信号来判断NACK反馈是否被发送;例如如果终端设备在所述物理资源上检测到第一信号,则判断NACK反馈被发送。
本发明实施例中,当所述第一操作为在物理资源接收第一信号时,所述物理资源位于数据包的传输期间;即所述物理资源的时域位置位于从分配给数据包的第一个子帧的起始时刻开始到分配给数据包的最后一个子帧的结束时刻为止这一时间范围内。在所述第一信号为用于ACK反馈的第一信号时,通过该方法,在上行数据包按照为该数据包分配的子帧数发送结束之前ACK反馈就能够被接收,从而终端设备能够提前终止该数据包的发送,最终减少了不必要的资源损耗和终端设备的功率损耗。
本发明实施例中,所述物理资源的时域位置位于分配给数据包的第K1个子帧之后和倒数第K2个子帧之前;其中,所述K1和K2是大于1的整数。例如,在第一信号为用于ACK反馈的第一信号时,在网络侧设备还没有完成数据包解码时,终端设备不需要监控ACK反馈;即该方法考虑了网络侧设备解码数据包的时延。
本发明实施例中,确定所述物理资源的时域位置的方式包括:
方式一,通过信令确定所述物理资源的时域位置;例如通过信令直接获取所述物理资源时域位置的起始子帧;
方式二,通过分配给数据包的最后1个子帧(即数据包发送的结束子帧)确定所述物理资源的时域位置;例如,所述物理资源的时域位置开始于数 据包发送结束之后的第Q1个子帧,所述Q1是大于1的整数;
方式三,通过信令确定所述物理资源候选时域位置;根据所述候选时域位置和分配给数据包的最后1个子帧(即数据包发送的结束子帧)确定所述物理资源的时域位置;例如,所述物理资源的时域位置是在所有候选的时域位置中开始于数据包发送的结束子帧后第Q2个子帧之后的第一个出现的时域位置,或者,所述物理资源的时域位置是在所有候选时域位置中开始于数据包发送的结束子帧后第Q2个子帧之后的第一个出现的与数据包的HARQ进程相对应的时域位置,或者,所述物理资源的时域位置是在所有候选时域位置中开始于数据包发送的结束子帧后第Q2个子帧之后的最先出现的连续Q3个时域位置,所述Q2是大于1整数,所述Q3是大于1整数。
其中,通过信令确定所述物理资源候选时域位置,包括:通过信令确定所述物理资源候选时域位置的起始子帧和大小。
方式四,通过信令确定所述物理资源的候选时域位置;根据所述候选时域位置和分配给数据包的子帧确定所述物理资源的时域位置;
例如,所述物理资源的时域位置是在所有候选的时域位置中开始于分配给数据包的第P1个子帧之后且结束于分配给数据包的倒数第P2个子帧之前的时域位置,所述P1和P2是大于1的整数;
其中,通过信令确定所述物理资源候选时域位置,包括:通过信令确定所述物理资源候选时域位置的起始子帧和大小。
方式五,根据分配给数据包的子帧数确定所述物理资源的时域位置;
例如所述物理资源的时域位置开始于分配给数据包的第x1*P3+1个子帧,其中,所述x1是等于1,2,…,X1-1的序列,所述X1是大于1整数,所述P3等于N/X1,所述N表示分配给数据包的子帧数;其中,所述X1取值为固定值或者是根据分配给数据包的子帧数(即N取值)确定的。
方式六,根据分配给数据包的子帧数和分配给所述物理资源的子帧数 确定所述物理资源的时域位置;例如所述物理资源的时域位置开始于分配给数据包的第x2*P4+1个子帧,所述x2是等于1,2,…,X2-1的序列,所述X2是大于1整数,所述P4等于N/X2,所述N表示分配给数据包的子帧数;其中,所述X2取值根据分配给数据包的子帧数(即N取值)和分配给所述物理资源的子帧数(即所述物理资源时域位置的大小)共同确定。
需要说明的是,本发明实施例中,所述物理资源时域位置的大小等价于分配给物理资源的子帧数;如果没有特别指出,所述物理资源时域位置的大小可以视为是通过信令确定的。
本发明实施例中,所述物理资源在频域上占用1个资源块或6个资源块(等价于占用1个窄带);
本发明实施例中,通过信令确定所述物理资源在频域上占用的资源块的位置。
本发明实施例中,在所述物理资源与终端设备专有搜索空间存在冲突时,放弃在所述物理资源接收所述第一信号;即在终端设备专有搜索空间接收下行控制信息的优先级更高。
本发明实施例中,对于HD-FDD,所述物理资源位于终端设备的上行间隙内;即所述物理资源的时域位置位于从上行间隙的第一个子帧的起始时刻开始到上行间隙的最后一个子帧的结束时刻为止这一时间范围内。需要说明的是,所述终端设备的上行间隙是在终端设备发送上行数据包期间定义的用于指定用途的发送间隙;在除发送上行数据包期间以外的其它时间段中定义间隙是没有任何意义的。例如,在第一信号为用于ACK反馈的第一信号时,由于处于HD-FDD模式的终端设备在发送上行数据包的同时无法接收第一信号,所以只能在发送数据包期间引入上行间隙用以实现接收第一信号的目的。
所述上行间隙为第一上行间隙或第二上行间隙;所述第一上行间隙是 终端设备用于下行时频同步的上行间隙,该上行间隙是触发在所述物理资源接收所述第一信号之前已有的上行间隙;所述第二上行间隙是(相对于触发在物理资源接收所述第一信号之前已有的上行间隙,例如第一上行间隙)新增加的上行间隙。需要说明的是,在所述上行间隙为第一上行间隙时,所述第一上行间隙除用于终端设备下行时频同步以外还用于终端设备接收反馈;在所述上行间隙为第二上行间隙时,所述第二上行间隙只用于终端设备接收反馈。
根据以下方式之一确定所述第二上行间隙的时域位置:
方式一,通过信令确定所述第二上行间隙的时域位置;例如通过信令直接获取第二上行间隙时域位置的起始子帧;
方式二,所述第二上行间隙的时域位置开始于所述第一上行间隙之后的第1个子帧(即所述第二上行间隙紧靠所述第一上行间隙);
方式三,通过信令确定所述第二上行间隙的候选时域位置;根据所述第二上行间隙的候选时域位置和分配给所述数据包的子帧确定所述第二上行间隙的时域位置;例如所述第二上行间隙的时域位置是在所有候选时域位置中开始于分配给数据包的第M1个子帧之后,并且结束于分配给数据包的倒数第M2个子帧之前的时域位置,其中,该M1和M2个是大于1的整数;
其中,通过信令确定所述第二上行间隙候选时域位置,包括以下之一:
通过信令确定所述第二上行间隙候选时域位置的起始子帧和大小;
通过信令确定所述第二上行间隙候选时域位置的起始子帧;根据所述物理资源时域位置的大小确定所述第二上行间隙候选时域位置的大小,例如所述第二上行间隙候选时域位置的大小等于所述物理资源时域位置的大小加上固定整数(比如该固定整数可以为2)。
方式四,根据分配给所述数据包的子帧数确定所述第二上行间隙的时域位置;例如所述第二上行间隙的时域位置开始于分配给数据包的第y1*M3 个子帧之后的第1个子帧,其中,所述y1是等于1,2,…,Y1-1的序列,所述Y1是大于1整数,所述M3等于N/Y1,所述N表示分配给数据包的子帧数;其中,所述Y1取值为固定值或者是根据分配给数据包的子帧数(即N取值)确定的;
方式五,根据分配给所述数据包的子帧数和分配给所述第二上行间隙的子帧数确定所述第二上行间隙的时域位置;例如所述第二上行间隙的时域位置开始于分配给数据包的第y2*M4个子帧之后的第1个子帧,所述y2是等于1,2,…,Y2-1的序列,所述Y2是大于1整数,所述M4等于N/Y2,所述N是分配给数据包的子帧数;其中,所述Y2取值根据分配给数据包的子帧数(即N取值)和分配给所述第二上行间隙时域位置的子帧数(即上行间隙时域位置的大小)共同确定。
需要说明的是,本发明实施例中,所述第二上行间隙时域位置的大小等价于分配给第二上行间隙的子帧数;如果没有特别指出,通过以下之一确定所述第二上行间隙时域位置的大小:
通过信令确定所述第二上行间隙时域位置的大小;
根据所述物理资源时域位置的大小确定所述第二上行间隙时域位置的大小,例如所述第二上行间隙时域位置的大小等于所述物理资源时域位置的大小加上固定整数(比如该固定整数可以为2)。
本发明实施例中,在所述第二上行间隙与所述第一上行间隙存在重叠时,放弃在所述第二上行间隙内的搜索空间接收下行控制信息,或者,推迟所述第二上行间隙。在采用推迟所述第二上行间隙的方式时,推迟后的所述第二上行间隙可以开始于所述第一上行间隙后的第1个子帧。

其中,一个公共的下行控制信息承载多个终端设备的反馈;一个终端设备专有的下行控制信息承载唯一终端设备的反馈;该反馈为所述ACK反馈或者所述NACK反馈。
其中,用于ACK反馈的所述终端设备专有的下行控制信息包括以下特征:

此时,作为一种选择,可以通过信令进一步指示所述第三搜索空间在所述窄带中占用的资源块集合;
方式二,根据所述第一搜索空间的窄带确定所述第三搜索空间的窄带。
其中,所述根据第一搜索空间的窄带确定第三搜索空间的窄带,包括:所述第三搜索空间的窄带与所述第一搜索空间的窄带相同。此时,作为一种选择,所述第三搜索空间在所述窄带中占用的资源块集合与所述第一搜索空间在所述窄带中占用的资源块集合相同。
本发明实施例中,在所述第三搜索空间与所述第一搜索空间(即终端设备专有搜索空间)存在冲突时,放弃在所述第三搜索空间发送所述下行控制信息;即在终端设备专有搜索空间发送下行控制信息的优先级更高。
本发明实施例中,确定所述第二搜索空间的时域位置的方式包括:
方式一,通过信令指示所述第二搜索空间的时域位置;例如通过信令直接指示第一搜索空间(触发前已有的终端设备专有搜索空间)中的哪些搜索空间是第二搜索空间。
方式二,根据第一搜索空间的时域位置和分配给数据包的最后1个子帧(即数据包发送的结束子帧)确定所述第二搜索空间的时域位置;例如,第二搜索空间的时域位置是在所有第一搜索空间的时域位置中开始于数据包发送的结束子帧后第D1个子帧之后的第一个出现的时域位置,或者,第二搜索空间的时域位置是在所有第一搜索空间的时域位置中开始于数据包发送的结束子帧后第D1个子帧之后的第一个出现的与数据包的HARQ进程相对应的时域位置,或者,第二搜索空间的时域位置是在所有第一搜索空间的时域位置中开始于数据包发送的结束子帧后第D1个子帧之后的最先出现的连续D2个时域位置,所述D1是大于1整数,所述D2是大于1整数。
方式三,根据第一搜索空间的时域位置和分配给数据包的子帧确定所述第二搜索空间的时域位置;例如,第二搜索空间的时域位置是在所有第一搜索空间的时域位置中开始于分配给数据包的第D3个子帧之后且结束于分配给数据包的倒数第D4个子帧之前的时域位置,所述D3和D4是大于1的整数。
本发明实施例中,对于半双工频分双工HD-FDD系统,所述第二搜索空间和/或第三搜索空间位于终端设备的上行间隙内(在所述搜索空间包括所述第二搜索空间和第三搜索空间至少之一时);即所述第二搜索空间和/或第三搜索空间的时域位置位于从上行间隙的第一个子帧的起始时刻开始到上行间隙的最后一个子帧的结束时刻为止这一时间范围内。需要说明的是,所述终端设备的上行间隙是在终端设备发送上行数据包期间定义的用于指定用途的发送间隙;在除发送上行数据包期间以外的其它时间段中定义间隙是没有任何意义的。例如,在下行控制信息为用于ACK反馈下行控 制信息时,由于处于HD-FDD模式的终端设备在发送上行数据包的同时无法接收下行数据,所以只能在发送数据包期间引入上行间隙用以实现接收下行控制信息的目的。
本发明实施例中,所述上行间隙为第一上行间隙或第二上行间隙;所述第一上行间隙是终端设备用于下行时频同步的上行间隙,所述第二上行间隙是(相对于触发前已有的上行间隙,例如第一上行间隙)新增加的上行间隙。需要说明的是,在所述上行间隙为第一上行间隙时,所述第一上行间隙除用于终端设备下行时频同步以外还用于终端设备接收反馈;在所述上行间隙为第二上行间隙时,所述第二上行间隙只用于终端设备接收反馈。
本发明实施例中,根据以下方式之一确定所述第二上行间隙的时域位置:
方式一,通过信令指示所述第二上行间隙的时域位置;例如通过信令直接指示第二上行间隙时域位置的起始子帧;
方式二,所述第二上行间隙的时域位置开始于所述第一上行间隙之后的第1个子帧(即所述第二上行间隙紧靠所述第一上行间隙);
方式三,通过信令指示所述第二上行间隙的候选时域位置,根据所述第二上行间隙的候选时域位置和分配给所述数据包的子帧确定所述第二上行间隙的时域位置;例如所述第二上行间隙的时域位置是在所有候选时域位置中开始于分配给数据包的第M1个子帧之后,并且结束于分配给数据包的倒数第M2个子帧之前的时域位置,其中,该M1和M2个是大于3的整数;该方式的具体实施过程,可参见第一实施例中关于该部分内容的示例描述。
其中,通过信令指示所述第二上行间隙候选时域位置,包括以下之一:
通过信令指示所述第二上行间隙候选时域位置的起始子帧和大小;
通过信令指示所述第二上行间隙候选时域位置的起始子帧;根据所述第二搜索空间或第三搜索空间时域位置的大小确定所述第二上行间隙候选时域位置的大小,例如所述第二上行间隙候选时域位置的大小等于所述第二搜索空间或第三搜索空间时域位置的大小加上固定整数(比如该固定整数可以为2)。
方式四,根据分配给所述数据包的子帧数确定所述第二上行间隙的时域位置;例如所述第二上行间隙的时域位置开始于分配给数据包的第y1*M3个子帧之后的第1个子帧,其中,所述y1是等于1,2,…,Y1-1的序列,所述Y1是大于1整数,所述M3等于N/Y1,所述N表示分配给数据包的子帧数;其中,所述Y1取值为固定值或者是根据分配给数据包的子帧数(即N取值)确定的;该方式的具体实施过程,可参见第一实施例中关于该部分内容的示例描述。
方式五,根据分配给所述数据包的子帧数和分配给所述第二上行间隙的子帧数确定所述第二上行间隙的时域位置。例如所述第二上行间隙的时域位置开始于分配给数据包的第y2*M4个子帧之后的第1个子帧,所述y2是等于1,2,…,Y2-1的序列,所述Y2是大于1整数,所述M4等于N/Y2,所述N是分配给数据包的子帧数;其中,所述Y2取值根据分配给数据包的子帧数(即N取值)和分配给所述第二上行间隙时域位置的子帧数(即上行间隙时域位置的大小)共同确定。
需要说明的是,本发明实施例中,所述第二上行间隙时域位置的大小等价于分配给第二上行间隙的子帧数;如果没有特别指出,通过以下之一确定所述第二上行间隙时域位置的大小:
通过信令指示所述第二上行间隙时域位置的大小;
根据所述第二搜索空间或第三搜索空间时域位置的大小确定所述第二上行间隙时域位置的大小,例如所述第二上行间隙时域位置的大小等于所 述第二搜索空间或第三搜索空间时域位置的大小加上固定整数(比如该固定整数可以为2)。
本实施例中,在所述第二上行间隙与所述第一上行间隙存在重叠时,放弃在所述第二上行间隙内的搜索空间发送下行控制信息,或者,推迟所述第二上行间隙。在采用推迟所述第二上行间隙的方式时,推迟后的所述第二上行间隙可以开始于所述第一上行间隙后的第1个子帧。
本实施例中,在所述上行间隙为第一上行间隙时,包括以下至少之一:
在所述搜索空间包括所述第三搜索空间时,所述第三搜索空间的窄带包含系统带宽中心的6个资源块(即第三搜索空间的窄带与传输同步信号和物理广播信道的窄带相同);用于发送同步信号和/或物理广播信道的子帧不用于发送所述下行控制信息(例如以用于发送物理广播信道的子帧不用于发送所述下行控制信息为例,设想在指定小区中,子帧#0和子帧#9用于发送物理广播信道,则子帧#0和子帧#9不用于发送所述下行控制信息)。终端设备的下行时频同步主要是基于同步信号和物理广播信道的接收;该方法有助于在接收下行控制信息的同时尽可能减少对同步信号和物理广播信道接收的影响。
本发明实施例中,当所述第一操作为在物理资源接收第一信号时,所述第一信号为以下之一:
用于下行时频同步的第一信号;
用于下行信道测量和信道估计的第一信号(即第一信号可以被视为下行的参考信号);
用于ACK反馈的第一信号;
用于NACK反馈的第一信号。
需要说明的是,当所述第一信号为用于ACK反馈的第一信号时,终端 设备通过是否在所述物理资源上检测到第一信号来判断ACK反馈是否被发送;例如如果终端设备在所述物理资源上检测到第一信号,则判断ACK反馈被发送。类似地,当所述第一信号为用于NACK反馈的第一信号时,终端设备通过是否在所述物理资源上检测到第一信号来判断NACK反馈是否被发送;例如如果终端设备在所述物理资源上检测到第一信号,则判断NACK反馈被发送。
本发明实施例中,当所述第一操作为在物理资源接收第一信号时,所述物理资源位于数据包的传输期间;即所述物理资源的时域位置位于从分配给数据包的第一个子帧的起始时刻开始到分配给数据包的最后一个子帧的结束时刻为止这一时间范围内。在所述第一信号为用于ACK反馈的第一信号时,通过该方法,在上行数据包按照为该数据包分配的子帧数发送结束之前ACK反馈就能够被接收,从而终端设备能够提前终止该数据包的发送,最终减少了不必要的资源损耗和终端设备的功率损耗。
本发明实施例中,所述物理资源的时域位置位于分配给数据包的第K1个子帧之后和倒数第K2个子帧之前;其中,所述K1和K2是大于1的整数。例如,在第一信号为用于ACK反馈的第一信号时,在网络侧设备还没有完成数据包解码时,终端设备不需要监控ACK反馈;即该方法考虑了网络侧设备解码数据包的时延。
本发明实施例中,确定所述物理资源的时域位置的方式包括:
方式一,通过信令指示所述物理资源的时域位置;例如通过信令直接指示所述物理资源时域位置的起始子帧;
方式二,通过分配给数据包的最后1个子帧(即数据包发送的结束子帧)确定所述物理资源的时域位置;例如,所述物理资源的时域位置开始于数据包发送结束之后的第Q1个子帧,所述Q1是大于1的整数;
方式三,通过信令指示所述物理资源候选时域位置;根据所述候选时 域位置和分配给数据包的最后1个子帧(即数据包发送的结束子帧)确定所述物理资源的时域位置;例如,所述物理资源的时域位置是在所有候选的时域位置中开始于数据包发送的结束子帧后第Q2个子帧之后的第一个出现的时域位置,或者,所述物理资源的时域位置是在所有候选时域位置中开始于数据包发送的结束子帧后第Q2个子帧之后的第一个出现的与数据包的HARQ进程相对应的时域位置,或者,所述物理资源的时域位置是在所有候选时域位置中开始于数据包发送的结束子帧后第Q2个子帧之后的最先出现的连续Q3个时域位置,所述Q2是大于1整数,所述Q3是大于1整数。
其中,通过信令指示所述物理资源候选时域位置,包括:通过信令指示所述物理资源候选时域位置的起始子帧和大小。
方式四,通过信令指示所述物理资源的候选时域位置;根据所述候选时域位置和分配给数据包的子帧确定所述物理资源的时域位置;
例如,所述物理资源的时域位置是在所有候选的时域位置中开始于分配给数据包的第P1个子帧之后且结束于分配给数据包的倒数第P2个子帧之前的时域位置,所述P1和P2是大于1的整数;
其中,通过信令指示所述物理资源候选时域位置,包括:通过信令指示所述物理资源候选时域位置的起始子帧和大小。
方式五,根据分配给数据包的子帧数确定所述物理资源的时域位置;
例如所述物理资源的时域位置开始于分配给数据包的第x1*P3+1个子帧,其中,所述x1是等于1,2,…,X1-1的序列,所述X1是大于1整数,所述P3等于N/X1,所述N表示分配给数据包的子帧数;其中,所述X1取值为固定值或者是根据分配给数据包的子帧数(即N取值)确定的。
方式六,根据分配给数据包的子帧数和分配给所述物理资源的子帧数确定所述物理资源的时域位置;例如所述物理资源的时域位置开始于分配给数据包的第x2*P4+1个子帧,所述x2是等于1,2,…,X2-1的序列,所述X2 是大于1整数,所述P4等于N/X2,所述N表示分配给数据包的子帧数;其中,所述X2取值根据分配给数据包的子帧数(即N取值)和分配给所述物理资源的子帧数(即所述物理资源时域位置的大小)共同确定。
需要说明的是,本发明实施例中,所述物理资源时域位置的大小等价于分配给物理资源的子帧数;如果没有特别指出,所述物理资源时域位置的大小可以视为是通过信令指示的。
本发明实施例中,所述物理资源在频域上占用1个资源块或6个资源块(等价于占用1个窄带);
本发明实施例中,通过信令指示所述物理资源在频域上占用的资源块的位置。
本发明实施例中,在所述物理资源与终端设备专有搜索空间存在冲突时,放弃在所述物理资源发送所述第一信号;即在终端设备专有搜索空间发送下行控制信息的优先级更高。
本发明实施例中,对于HD-FDD,所述物理资源位于终端设备的上行间隙内;即所述物理资源的时域位置位于从上行间隙的第一个子帧的起始时刻开始到上行间隙的最后一个子帧的结束时刻为止这一时间范围内。需要说明的是,所述终端设备的上行间隙是在终端设备发送上行数据包期间定义的用于指定用途的发送间隙;在除发送上行数据包期间以外的其它时间段中定义间隙是没有任何意义的。例如,在第一信号为用于ACK反馈的第一信号时,由于处于HD-FDD模式的终端设备在发送上行数据包的同时无法接收第一信号,所以只能在发送数据包期间引入上行间隙用以实现接收第一信号的目的。
所述上行间隙为第一上行间隙或第二上行间隙;所述第一上行间隙是终端设备用于下行时频同步的上行间隙,该上行间隙是触发在所述物理资源接收所述第一信号之前已有的上行间隙;所述第二上行间隙是(相对于 触发在物理资源接收所述第一信号之前已有的上行间隙,例如第一上行间隙)新增加的上行间隙。需要说明的是,在所述上行间隙为第一上行间隙时,所述第一上行间隙除用于终端设备下行时频同步以外还用于终端设备接收反馈;在所述上行间隙为第二上行间隙时,所述第二上行间隙只用于终端设备接收反馈。
根据以下方式之一确定所述第二上行间隙的时域位置:
方式一,通过信令指示所述第二上行间隙的时域位置;例如通过信令直接指示第二上行间隙时域位置的起始子帧;
