下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清 楚、 完整地描述, 显然, 所描述的实施例仅仅是本发明一部分实施例, 而不是 全部的实施例。基于本发明中的实施例, 本领域技术人员在没有作出创造性劳 动前提下所获得的所有其他实施例, 都属于本发明保护的范围。
本发明实施例提供一种系统消息的覆盖增强传输装置、 系统和方法。 以下 分别进行详细说明。 实施例一、
本发明实施例提供一种网络侧设备, 如图 la所示, 该网络侧设备包括确定 单元 101和传输单元 102, 如下:
确定单元 101 , 用于确定配置信息, 其中, 配置信息用于指示系统消息窗 内的系统消息传输配置;
其中,系统消息窗内的系统消息传输配置可以包括传输系统消息时使用的 子帧信息, 此外, 可选的, 该系统消息传输配置还可以包括系统消息的传输次 数, 其中, 系统消息的传输次数也可以根据传输系统消息时使用的子帧信息来 确定。
需说明的是,不同的系统消息可以有不同的系统消息窗内的系统消息传输 配置,也可以有相同的系统消息窗内的系统消息传输配置; 相同的系统消息可 以有不同的系统消息窗内的系统消息传输配置,也可以有相同的系统消息窗内 的系统消息传输配置,比如,同样需要在一个系统消息窗内传输两次系统消息, 那么, 如果系统消息窗的窗长度为 10毫秒(ms, millisecond) , 那么, 就可以 从这 10ms长的 10个子帧( lms也是一个子帧的长度) 中, 任意选择两个可用子 帧来传输两次系统消息。 其中, 所谓的可用子帧, 是指排除以下情况的子帧, :¾口下:
( 1 )满足系统帧号( SFN, System Frame Number ) mod 2 = 0无线帧( RF,
Radio Frame ) 中的 5号子帧。
其中, 一个无线帧是 10个子帧, 也就是 10ms。
( 2 ) 任何多播广播单频网络 ( MBSFN , Multicast Broadcast Single Frequency Network )子†贞。
( 3 )时分双工( TDD, Time Division Duplexing )系统中, 任何上行子帧。 其中, 可以通过枚举的方式, 罗列出系统消息窗中用于系统消息传输的子 帧编号。
传输单元 102, 用于在该配置信息所指示的资源上发送系统消息, 以便终 端设备根据该配置信息接收系统消息。
其中, 该配置信息可以通过与终端设备约定的方式让终端设备知晓,也可 以由网络侧设备直接确定后, 通知终端设备, 如果通过与终端设备约定的方式 让终端设备知晓, 贝' J :
确定单元 101 , 具体可以用于按照与终端设备约定的配置规则确定配置信 息。
而如果是采用直接通知终端设备的方式,则该网络侧设备还可以包括通知 单元, 如下:
通知单元, 用于将该配置信息通知给终端设备。
其中,如果系统消息传输配置指示该系统消息窗内的所有可用子帧都传输 系统消息, 则此时, 可以在该系统消息窗内的所有可用子帧上发送系统消息。 即:
传输单元 102, 具体用于在系统消息传输配置指示该系统消息窗内的所有 可用子帧都传输系统消息时,在该系统消息窗内的所有可用子帧上发送系统消 息。 如果系统传输配置指示该系统消息窗内的某些子帧传输系统消息, 则此 时, 可以在这些指定的子帧上发送系统消息。 即:
传输单元 102 , 具体用于在选择的子帧上发送系统消息。
其中, 确定单元 101在确定配置信息 (即系统消息窗内的系统消息传输配 置) 时, 可以采用多种方式, 例如, 具体可以如下:
( 1 )第一种方式;
可以先获取系统消息配置,然后根据系统消息配置来确定该配置信息,即: 确定单元 101 , 具体可以用于获取系统消息配置, 根据获取的系统消息配 置确定配置信息。
例如, 可以先定义系统消息配置和配置信息(即系统消息传输配置)之间 的对应关系, 然后, 在获取到系统消息配置之后, 通过查询该对应关系, 便可 以得到对应的配置信息 (即系统消息传输配置)。
上述系统消息配置和配置信息 (即系统消息传输配置)之间的对应关系, 可以由网络侧设备和终端设备根据一定的配置规则确定的,也可以由网络侧设 备确定, 并通知给终端设备, 比如, 可以由网络侧设备确定一个用于记录 "系 统消息配置和配置信息 (即系统消息传输配置)之间的对应关系 "的映射表, 然后将该映射表通知给终端设备, 等等。
其中, 该系统消息配置可以包括系统消息窗的窗长度( si-WindowLength ) 的配置和系统消息的周期 (si-Periodicity ) 的配置等, 此外, 该系统消息配置 还可以包括系统消息更新周期等。 例如, 其中, 系统消息窗的窗长度可以是 ( msl, ms2, ms5, mslO, msl5, ms20,ms40 )等,而系统消息窗的周期可以是( rf8, rfl6, rf32, rf64, rfl28, rf256, rf512 )等, 其中, rf指的是无线帧( Radio Frame )。
需说明的是, 不同的系统消息可以有不同的系统消息配置,也可以有相同 的系统消息配置;同一个系统消息的系统消息配置也可以 ^据实际应用的需求 进行调整的,即基站可以根据需求选择合适的系统消息窗的窗长度和系统消息 的周期, 组成系统消息配置。
( 2 )第二种方式;
具体可以先获取系统消息的覆盖增强需求信息、覆盖增强等级信息、重复 次数要求信息和 /或终端设备的尝试接收次数要求信息等信息 (即获取系统消 息的覆盖增强需求信息、覆盖增强等级信息、重复次数要求信息和终端设备的 尝试接收次数要求信息等信息中一个或多个), 然后根据获取到的系统消息的 覆盖增强需求信息、 覆盖增强等级信息、 重复次数要求信息和 /或终端设备的 尝试接收次数要求信息等信息来系统消息窗内的系统消息传输配置, 即:
确定单元 101 , 具体可以用于获取系统消息的覆盖增强需求信息、 覆盖增 强等级信息、 重复次数要求信息和 /或终端设备的尝试接收次数要求信息等信 息; 根据获取到的系统消息的覆盖增强需求信息、 覆盖增强等级信息、 重复次 数要求信息和 /或终端设备的尝试接收次数要求信息确定系统消息窗内的系统 消息传输配置。
上述各种需求信息(即系统消息的覆盖增强需求信息、覆盖增强等级信息、 重复次数要求信息和 /或终端设备的尝试接收次数要求信息等信息 )和配置信 息 (即系统消息传输配置)之间的对应关系, 可以由网络侧设备和终端设备根 据一定的配置规则确定的, 也可以由网络侧设备确定, 并通知给终端设备, 比 如, 可以由网络侧设备确定一个用于记录 "需求信息(即系统消息的覆盖增强 需求信息、 覆盖增强等级信息、 重复次数要求信息和 /或终端设备的尝试接收 次数要求信息等信息)和配置信息(即系统消息传输配置)之间的对应关系 "的 映射表, 然后将该映射表通知给终端设备, 等等。
另外, 需说明的是, 系统消息的覆盖增强需求信息、 覆盖增强等级信息、 重复次数要求信息和 /或终端设备的尝试接收次数要求信息等信息的设置可以 采用多种策略, 比如, 系统消息的覆盖增强需求信息、 覆盖增强等级信息、 重 复次数要求信息和 /或终端设备的尝试接收次数要求信息等信息, 可以是专门 为系统消息而设置的。 或者, 也可以设置终端设备的覆盖增强等级, 根据终端 设备的覆盖增强等级确定系统消息的覆盖增强等级,然后再根据系统消息的覆 盖增强等级来确定这些信息(即系统消息的覆盖增强需求信息、覆盖增强等级 信息、重复次数要求信息和 /或终端设备的尝试接收次数要求信息等信息),在 此不再赘述。
其中, 系统消息的覆盖增强需求信息、 覆盖增强等级信息、 重复次数要求 信息和 /或终端设备的尝试接收次数要求信息等的具体说明可以如下:
( 1 )覆盖增强需求;
系统消息窗中系统消息传输配置还可能与系统消息覆盖增强需求有关,不 同的覆盖增强需求可以对应不同的系统消息窗中系统消息传输配置。 比如,覆 盖增强需求 1可能需要在系统消息窗中传输 2次系统消息, 那么, 就需要在系统 消息窗中选择两个子帧传输系统消息; 覆盖增强需求 2可能需要在系统消息窗 中传输 5次系统消息, 那么, 就需要在系统消息窗中选择五个子帧传输系统消 息。 如果系统消息只有一个覆盖增强需求, 那么, 该项可以省略或者忽略。
( 2 )覆盖增强等级;
覆盖增强等级和覆盖增强需求可以是一一对应的,一个覆盖增强需求对应 一个覆盖增强等级; 一个覆盖增强需求还可以对应多个覆盖增强等级。
( 3 )重复次数需求;
信号重复是覆盖增强的技术之一, 不同的信号重复次数, 可以满足不同的 覆盖增强需求, 也可以对应不同的覆盖增强等级。
( 4 )终端设备尝试接收次数需求;
终端设备尝试接收(keep trying ), 也是一种覆盖增强技术, 不同的终端设 备尝试接收次数, 可以提供不同的增强增益。
其中, 信号重复(即重复次数要求信息)和"终端设备尝试接收", 作为两 种覆盖增强技术, 可以联合使用, 不同的重复次数和不同的终端设备尝试接收 次数的组合, 可以满足不同的覆盖增强需求。
具体的, 在对系统消息窗进行配置时, 也可以将覆盖增强需求、 覆盖增强 等级、 重复次数需求和 /或终端设备尝试接收次数需求也配置在其中, 例如, 如图 lb所示, 该图为系统消息窗中的配置示意图, 可见, 其中可以包括 n个覆 盖增强需求、 m个覆盖增强等级、 X个重复次数需求、 y个终端设备尝试接收次 数需求、 z个系统消息配置和 c个系统消息窗内的系统消息传输配置, 其中, n、 m、 x、 y、 z和 c可以根据实际应用的需求进行设置。
在图 lb的各个字段中, 标为 "可选" 的字段即表示可以该字段为可选项, 可以根据实际应用的需求进行增加或删减。 可选的, 系统消息窗中的配置还可以如图 lc所示, 即将覆盖增强需求、 覆 盖增强等级、 重复次数需求、 终端设备尝试接收次数需求、 系统消息配置和系 统消息窗内的系统消息传输配置的各种组合均显示出来, 其中, "#sij"指 "sij" 号子帧。
其中, 确定单元 101在确定配置信息 (即系统消息窗内的系统消息传输配 置)时, 可以先根据获取到的系统消息的覆盖增强需求信息、 覆盖增强等级信 息、 重复次数要求信息和 /或终端设备的尝试接收次数要求信息等信息来确定 系统消息配置, 然后 ^据确定的系统消息配置来确定该配置信息,也可以预先 设置系统消息的覆盖增强需求信息、覆盖增强等级信息、重复次数要求信息和 /或终端设备的尝试接收次数要求信息等信息和该配置信息的对应关系, 然后 在获取到系统消息的覆盖增强需求信息、覆盖增强等级信息、重复次数要求信 息和 /或终端设备的尝试接收次数要求信息等信息后, 通过查找该对应关系来 确定对应的配置信息;或者,还可以获取系统消息配置,根据该系统消息配置、 结合获取到的系统消息的覆盖增强需求信息、覆盖增强等级信息、重复次数要 求信息和 /或终端设备的尝试接收次数要求信息等信息来确定配置信息, 即: 确定单元 101 ,具体可以用于根据获取到的系统消息的覆盖增强需求信息、 覆盖增强等级信息、 重复次数要求信息和 /或终端设备的尝试接收次数要求信 息确定系统消息配置, ^据确定的系统消息配置确定配置信息; 或者,
确定单元 101 , 除了获取系统消息的覆盖增强需求信息、 覆盖增强等级信 息、 重复次数要求信息和 /或终端设备的尝试接收次数要求信息等信息之外, 还可以获取系统消息配置, 然后根据获取到的系统消息配置、结合获取到的系 统消息的覆盖增强需求信息、 覆盖增强等级信息、 重复次数要求信息和 /或终 端设备的尝试接收次数要求信息等信息来确定配置信息; 或者,
确定单元 101 ,具体可以用于根据获取到的系统消息的覆盖增强需求信息、 覆盖增强等级信息、 重复次数要求信息和 /或终端设备的尝试接收次数要求信 息等信息直接确定配置信息, 具体可以如下:
确定单元 101 ,具体可以用于根据获取到的系统消息的覆盖增强需求信息、 覆盖增强等级信息、 重复次数要求信息和 /或终端设备的尝试接收次数要求信 息确定系统消息的传输次数(即系统消息总的传输次数), 获取系统消息窗的 窗长度, 根据该窗长度和传输次数确定传输系统消息时使用的子帧信息。
其中, 可以通过多种方式来获取系统消息窗的窗长度, 比如, 可以获取系 统消息配置, 然后从系统消息配置中提取该系统消息窗的窗长度, 等等。
其中, 子帧信息可以包括至少子帧位置, 此外, 该子帧信息还可以包括子 帧数等信息, 即该子帧信息可以指示具体用多少子帧、 以及哪些子帧来传输该 系统消息。
此外,在选择传输系统消息的子帧时, 如果系统消息窗的窗长度不足以传 输 N个系统消息, 还可以对该系统消息窗进行扩展, 以便后续可以在该扩展后 的系统消息窗中选择子帧, 以传输系统消息。 其中, N为该系统消息窗内系统 消息的传输次数, 且 N为大于 0的整数。 即:
确定单元 101 , 具体可以用于在该窗长度(即系统消息窗的窗长度)足以 传输 N个系统消息时, 从系统消息窗中选择子帧, 以传输系统消息; 在该窗长 度不足以传输 N个系统消息时, 扩展系统消息窗, 从扩展后的系统消息窗中选 择子帧, 以传输系统消息。
当然, 在窗长度(即系统消息窗的窗长度)足以传输 N个系统消息时, 确 定单元 101也可以扩展系统消息窗, 从扩展后的系统消息窗中选择子帧, 以传 输系统消息。
可选的,也可以不扩展系统消息窗, 而是从连续的多个系统消息窗来选择 子帧来传输系统消息, 即:

可选的,还可以根据系统消息的周期来确定是采用扩展系统消息窗的方式 还是采用利用连续的多个系统消息窗的方式, 比如, 若系统消息的周期较长, 则采用扩展系统消息窗的方式, 而如果系统消息的周期较短, 则采用利用连续 的多个系统消息窗的方式, 即具体可以如下:
确定单元 101 , 具体用于获取系统消息的周期, 确定该系统消息的周期是 否超过预置周期阈值; 若超过该周期阈值, 则在确定所述窗长度足以传输 N个 系统消息时, 从系统消息窗中选择子帧, 以传输系统消息, 或者扩展系统消息 窗, 从扩展后的系统消息窗中选择子帧, 以传输系统消息; 在该窗长度不足以 传输 N个系统消息 (N为系统消息的传输次数) 时, 扩展系统消息窗, 从扩展 后的系统消息窗中选择子帧, 以传输系统消息; 若未超过该周期阈值, 则根据 所述窗长度和传输次数从连续的多个系统消息窗中选择子帧, 以传输系统消 息。
其中, 该周期阈值可以根据实际应用的需求进行设置, 在此不再赘述。 可选的,在需要终端设备的尝试接收次数较多时,如果仅仅使用原系统消 息窗的资源, 则终端设备接收系统消息的时间可能会比较长, 因此, 为了减少 终端设备接收系统消息的时间, 此时也可以对系统消息窗进行扩展, 即: 确定单元 101 , 具体可以用于根据该终端设备的尝试接收次数要求信息确 定终端设备的尝试接收次数,在确定该尝试接收次数大于预置阈值时,扩展系 统消息窗,根据该系统消息窗的窗长度和系统消息窗内系统消息的传输次数从 扩展后的系统消息窗中选择子帧, 以传输系统消息。
当然, 由于对系统消息窗进行了扩展, 因此, 同一个系统消息窗内可以传 输的系统消息次数也会增多, 所以, 此时终端设备的尝试接收次数也可以相应 的减少。 此外, 当终端设备的尝试接收次数较多时, 可以选择较小的系统消息 周期, 在此不再赘述。

基站设备, 具体可以用于获取系统消息的周期,确定该系统消息的周期是 否超过预置周期阈值; 若超过该周期阈值, 则在确定所述窗长度足以传输 N个 系统消息时, 从系统消息窗中选择子帧, 以传输系统消息, 或者扩展系统消息 窗, 从扩展后的系统消息窗中选择子帧, 以传输系统消息; 在该窗长度不足以 传输 N个系统消息 (N为系统消息的传输次数) 时, 扩展系统消息窗, 从扩展 后的系统消息窗中选择子帧, 以传输系统消息; 若未超过该周期阈值, 则根据 所述窗长度和传输次数从连续的多个系统消息窗中选择子帧, 以传输系统消 息。
则此时, 终端设备, 具体可以用于获取系统消息的周期, 确定该系统消息 的周期是否超过预置周期阈值; 若超过该周期阈值, 则在确定所述窗长度足以 传输 N个系统消息时, 从系统消息窗中选择子帧, 以接收基站设备发送的系统 消息, 或者扩展系统消息窗, 从扩展后的系统消息窗中选择子帧, 以接收基站 设备发送的系统消息; 在该窗长度不足以传输 N个系统消息 (N为系统消息的 传输次数)时, 扩展系统消息窗, 从扩展后的系统消息窗中选择子帧, 以接收 基站设备发送的系统消息; 若未超过该周期阈值, 则根据该窗长度和传输次数 从连续的多个系统消息窗中选择子帧, 以传输系统消息。
其中, 该周期阈值可以根据实际应用的需求进行设置, 在此不再赘述。 可选的,在需要终端设备的尝试接收次数较多时,如果仅仅使用原系统消 息窗的资源, 则终端设备接收系统消息的时间可能会比较长, 因此, 为了减少 终端设备接收系统消息的时间, 此时也可以对系统消息窗进行扩展, 即: 基站设备,具体可以用于根据该终端设备的尝试接收次数要求信息确定终 端设备的尝试接收次数,在确定该尝试接收次数大于预置阈值时,扩展系统消 息窗,根据该系统消息窗的窗长度和系统消息窗内系统消息的传输次数从扩展 后的系统消息窗中选择子帧, 以传输系统消息。
则此时, 终端设备, 具体可以用于根据该终端设备的尝试接收次数要求信 息确定终端设备的尝试接收次数,在确定该尝试接收次数大于预置阈值时, 扩 展系统消息窗,根据该系统消息窗的窗长度和系统消息窗内系统消息的传输次 数从扩展后的系统消息窗中选择子帧, 以接收基站设备发送的系统消息。
当然, 由于对系统消息窗进行了扩展, 因此, 同一个系统消息窗内可以传 输的系统消息次数也会增多, 所以, 此时终端设备的尝试接收次数也可以相应 的减少。 此外, 当终端设备的尝试接收次数较多时, 可以选择较小的系统消息 周期, 在此不再赘述。
此外, 该通信系统还可以包括其他的设备, 在此不再赘述。 该通信系统的具体实施将在以下的其他实施例中作进一步进行详细说明。 由上可知, 本实施例的通信系统采用确定配置信息, 其中, 该配置信息用 于指示系统消息窗内的系统消息传输配置,然后在该配置信息所指示的资源上 传输系统消息。 由于在该方案中, 可以通过通知或与终端设备约定的方式, 让 终端设备确切知道系统消息配置和系统消息窗内的系统消息传输配置, 所以, 有利于后续终端设备进行接收合并以及接收尝试等操作,可以降低终端设备的 处理复杂度, 提高覆盖增强的效果。
此外, 本发明实施例还提供相应的系统消息的覆盖增强传输方法, 以下将 在实施四和五中分别从网络侧设备和终端设备的角度对该系统消息的覆盖增 强传输方法进行说明。 实施例四、

一种系统消息的覆盖增强传输方法, 包括: 确定配置信息, 其中, 该配置 信息用于指示系统消息窗内的系统消息传输配置;在该配置信息所指示的资源 上发送系统消息, 以便终端设备根据该配置信息接收该系统消息。
如图 3所示, 具体流程可以如下:

需说明的是,不同的系统消息可以有不同的系统消息窗内的系统消息传输 配置,也可以有相同的系统消息窗内的系统消息传输配置; 相同的系统消息可 以有不同的系统消息窗内的系统消息传输配置,也可以有相同的系统消息窗内 的系统消息传输配置,比如,同样需要在一个系统消息窗内传输两次系统消息, 那么, 如果系统消息窗的窗长度为 10毫秒(ms, millisecond) , 那么, 就可以 从这 10ms长的 10个子帧( lms也是一个子帧的长度) 中, 任意选择两个可用子 帧来传输两次系统消息。

其中, 该系统消息配置可以包括系统消息窗的窗长度( si-WindowLength ) 的配置和系统消息的周期 (si-Periodicity ) 的配置等, 此外, 该系统消息配置 还可以包括系统消息更新周期等。 例如, 其中, 系统消息窗的窗长度可以是 ( msl, ms2, ms5, mslO, msl5, ms20,ms40 )等,而系统消息窗的周期可以是( rf8, rfl 6, rf32, rf64, rfl 28, rf256, rf512 )等, 其中, rf指的是无线帧。 需说明的是, 不同的系统消息可以有不同的系统消息配置,也可以有相同 的系统消息配置;同一个系统消息的系统消息配置也可以 ^据实际应用的需求 进行调整的,即基站可以根据需求选择合适的系统消息窗的窗长度和系统消息 的周期, 组成系统消息配置。
( 2 )第二种方式;

上述各种需求信息(即系统消息的覆盖增强需求信息、覆盖增强等级信息、 重复次数要求信息和 /或终端设备的尝试接收次数要求信息等信息 )和配置信 息 (即系统消息传输配置)之间的对应关系, 可以由网络侧设备和终端设备根 据一定的配置规则确定的, 也可以由网络侧设备确定, 并通知给终端设备, 比 如, 可以由网络侧设备确定一个用于记录 "需求信息(即系统消息的覆盖增强 需求信息、 覆盖增强等级信息、 重复次数要求信息和 /或终端设备的尝试接收 次数要求信息等信息)和配置信息(即系统消息传输配置)之间的对应关系 "的 映射表, 然后将该映射表通知给终端设备, 等等。
另外, 需说明的是, 系统消息的覆盖增强需求信息、 覆盖增强等级信息、 重复次数要求信息和 /或终端设备的尝试接收次数要求信息等信息的设置可以 采用多种策略, 比如, 系统消息的覆盖增强需求信息、 覆盖增强等级信息、 重 复次数要求信息和 /或终端设备的尝试接收次数要求信息等信息, 可以是专门 为系统消息而设置的。 或者, 也可以设置终端设备的覆盖增强等级, 根据终端 设备的覆盖增强等级确定系统消息的覆盖增强等级,然后再根据系统消息的覆 盖增强等级来确定这些信息(即系统消息的覆盖增强需求信息、覆盖增强等级 信息、重复次数要求信息和 /或终端设备的尝试接收次数要求信息等信息),在 此不再赘述。
其中, 系统消息的覆盖增强需求信息、 覆盖增强等级信息、 重复次数要求 信息和 /或终端设备的尝试接收次数要求信息等的具体说明可参见前面的实施 例, 在此不再赘述。
具体的, 在对系统消息窗进行配置时, 也可以将覆盖增强需求、 覆盖增强 等级、 重复次数需求和 /或终端设备尝试接收次数需求也配置在其中, 例如, 可参见图 lb, 在此不再赘述。

其中, 在确定配置信息(即系统消息窗内的系统消息传输配置)时, 可以 先根据获取到的系统消息的覆盖增强需求信息、覆盖增强等级信息、重复次数 要求信息和 /或终端设备的尝试接收次数要求信息等信息来确定系统消息配 置, 然后根据确定的系统消息配置来确定该配置信息,也可以预先设置系统消 息的覆盖增强需求信息、 覆盖增强等级信息、 重复次数要求信息和 /或终端设 备的尝试接收次数要求信息等信息和该配置信息的对应关系,然后在获取到系 统消息的覆盖增强需求信息、 覆盖增强等级信息、 重复次数要求信息和 /或终 端设备的尝试接收次数要求信息等信息后,通过查找该对应关系来确定对应的 配置信息; 或者, 还可以获取系统消息配置, 根据该系统消息配置、 结合获取 到的系统消息的覆盖增强需求信息、覆盖增强等级信息、重复次数要求信息和 /或终端设备的尝试接收次数要求信息等信息来确定配置信息, 即步骤 "根据 获取到的系统消息的覆盖增强需求信息、覆盖增强等级信息、重复次数要求信 息和 /或终端设备的尝试接收次数要求信息确定配置信息" 具体可以包括: 根据获取到的系统消息的覆盖增强需求信息、覆盖增强等级信息、重复次 数要求信息和 /或终端设备的尝试接收次数要求信息确定系统消息配置; 根据 确定的系统消息配置确定配置信息。
或者, 除了获取系统消息的覆盖增强需求信息、 覆盖增强等级信息、 重复 次数要求信息和 /或终端设备的尝试接收次数要求信息等信息之外, 还可以获 取系统消息配置, 然后根据获取到的系统消息配置、结合获取到的系统消息的 覆盖增强需求信息、 覆盖增强等级信息、 重复次数要求信息和 /或终端设备的 尝试接收次数要求信息等信息来确定配置信息。
或者,还可以根据获取到的系统消息的覆盖增强需求信息、覆盖增强等级 信息、 重复次数要求信息和 /或终端设备的尝试接收次数要求信息等信息直接 确定配置信息, 例如, 具体可以如下:
根据获取到的系统消息的覆盖增强需求信息、覆盖增强等级信息、重复次 数要求信息和 /或终端设备的尝试接收次数要求信息确定系统消息的传输次 数; 获取系统消息窗的窗长度; 根据该窗长度和传输次数确定传输系统消息时 使用的子帧信息。
其中, 可以通过多种方式来获取系统消息窗的窗长度, 比如, 可以获取系 统消息配置, 然后从系统消息配置中提取该系统消息窗的窗长度, 等等。
其中, 子帧信息可以包括至少子帧位置, 此外, 该子帧信息还可以包括子 帧数等信息, 即该子帧信息可以指示具体用多少子帧、 以及哪些子帧来传输该 系统消息。
此外,在选择传输系统消息的子帧时, 如果系统消息窗的窗长度不足以传 输 N个系统消息, 还可以对该系统消息窗进行扩展, 以便后续可以在该扩展后 的系统消息窗中选择子帧, 以传输系统消息。 其中, N为该系统消息窗内系统 消息的传输次数, 且 N为大于 0的整数。 即步骤 "根据该窗长度和传输次数确 定传输系统消息时使用的子帧信息 " 具体可以包括:
若该窗长度足以传输 N个系统消息, 则从系统消息窗中选择子帧, 以传输 系统消息, 或者扩展系统消息窗, 从扩展后的系统消息窗中选择子帧, 以传输 系统消息;
若该窗长度不足以传输 N个系统消息, 则扩展系统消息窗, 从扩展后的系 统消息窗中选择子帧, 以传输系统消息。
可选的,也可以不扩展系统消息窗, 而是从连续的多个系统消息窗来选择 子帧来传输系统消息, 即步骤 "根据该窗长度和传输次数确定传输系统消息时 使用的子帧信息" 具体可以包括:
根据该窗长度和传输次数从连续的多个系统消息窗中选择子帧,以传输系 统消息。
可选的,还可以根据系统消息的周期来确定是采用扩展系统消息窗的方式 还是采用利用连续的多个系统消息窗的方式, 比如, 若系统消息的周期较长, 则采用扩展系统消息窗的方式, 而如果系统消息的周期较短, 则采用利用连续 的多个系统消息窗的方式, 即该系统消息的覆盖增强传输方法还可以包括: 获取系统消息的周期;
则此时, 步骤 "根据该窗长度和传输次数确定传输系统消息时使用的子帧 信息" 具体可以包括:
确定该系统消息的周期是否超过预置周期阈值;
若超过所述周期阈值, 则在确定所述窗长度足以传输 N个系统消息时, 从 系统消息窗中选择子帧, 以传输系统消息, 或者扩展系统消息窗, 从扩展后的 系统消息窗中选择子帧, 以传输系统消息; 在所述窗长度不足以传输 N个系统 消息时, 扩展系统消息窗, 从扩展后的系统消息窗中选择子帧, 以传输系统消 息;
若未超过所述周期阈值,则根据所述窗长度和传输次数从连续的多个系统 消息窗中选择子帧, 以传输系统消息。
其中, 该周期阈值可以根据实际应用的需求进行设置, 在此不再赘述。 可选的,在需要终端设备的尝试接收次数较多时,如果仅仅使用原系统消 息窗的资源, 则终端设备接收系统消息的时间可能会比较长, 因此, 为了减少 终端设备接收系统消息的时间, 此时也可以对系统消息窗进行扩展, 即在步骤 "根据该窗长度和传输次数确定传输系统消息时使用的子帧的信息"之前, 该 系统消息的覆盖增强传输方法还可以包括:
根据该终端设备的尝试接收次数要求信息确定终端设备的尝试接收次数, 确定所述尝试接收次数大于预置阈值时, 扩展系统消息窗;
则步骤 "根据该窗长度和传输次数确定传输系统消息时使用的子帧的信 息" 具体为:

302、 在该配置信息所指示的资源上发送系统消息, 以便终端设备根据该 配置信息接收该系统消息。
其中,如果系统消息传输配置指示该系统消息窗内的所有可用子帧都传输 系统消息, 则此时, 可以在该系统消息窗内的所有可用子帧上发送系统消息。 即步骤 "该配置信息所指示的资源上发送系统消息" 具体可以为:

而如果系统传输配置指示该系统消息窗内的某些子帧传输系统消息,则此 时, 可以在这些指定的子帧上发送系统消息。 即步骤 "该配置信息所指示的资 源上发送系统消息 " 具体可以为:

501、 基站设备获取系统消息的覆盖增强需求信息、 覆盖增强等级信息、 重复次数要求信息和 /或终端设备的尝试接收次数要求信息。
502、 基站设备根据获取到的系统消息的覆盖增强需求信息、 覆盖增强等 级信息、 重复次数要求信息和 /或终端设备的尝试接收次数要求信息确定配置 信息, 其中, 该配置信息指示系统消息窗内的系统消息传输配置。
其中, 在确定配置信息(即系统消息窗内的系统消息传输配置)时, 可以 先根据获取到的系统消息的覆盖增强需求信息、覆盖增强等级信息、重复次数 要求信息和 /或终端设备的尝试接收次数要求信息等信息来确定系统消息配 置, 然后根据确定的系统消息配置来确定该配置信息,也可以预先设置系统消 息的覆盖增强需求信息、 覆盖增强等级信息、 重复次数要求信息和 /或终端设 备的尝试接收次数要求信息等信息和该配置信息的对应关系,然后在获取到系 统消息的覆盖增强需求信息、 覆盖增强等级信息、 重复次数要求信息和 /或终 端设备的尝试接收次数要求信息等信息后,通过查找该对应关系来确定对应的 配置信息; 或者, 还可以获取系统消息配置, 根据该系统消息配置、 结合获取 到的系统消息的覆盖增强需求信息、覆盖增强等级信息、重复次数要求信息和 /或终端设备的尝试接收次数要求信息等信息来确定配置信息。
其中, 若是根据获取到的系统消息的覆盖增强需求信息、覆盖增强等级信 息、 重复次数要求信息和 /或终端设备的尝试接收次数要求信息等信息直接确 定配置信息, 则具体可以如下:
根据获取到的系统消息的覆盖增强需求信息、覆盖增强等级信息、重复次 数要求信息和 /或终端设备的尝试接收次数要求信息等信息确定系统消息的传 输次数, 然后获取系统消息窗的窗长度,再根据该系统消息窗的窗长度和系统 消息的传输次数确定传输系统消息时使用的子帧信息。
其中, 可以通过多种方式来获取系统消息窗的窗长度, 比如, 可以获取系 统消息配置, 然后从系统消息配置中提取该系统消息窗的窗长度, 等等。
其中, 子帧信息可以包括至少子帧位置, 此外, 该子帧信息还可以包括子 帧数等信息, 即该子帧信息可以指示具体用多少子帧、 以及哪些子帧来传输该 系统消息。
其中,在进行系统消息窗内的系统消息传输配置时, 可以采用多种方式来 满足覆盖增强需求信息, 具体可以如下:
( 1 )通过重复传输满足覆盖增强需求。
即可以通过不同的重复次数来满足不同的覆盖增强需求, 其中:
A、 不同的覆盖增强需求, 对应不同的重复次数, 那么, 系统消息窗中需 要发送的系统消息的次数也不相同, 则此时, 需要的子帧数和相应的子帧位置 也不相同, 即对应着不同的系统消息窗内系统消息传输配置;
B、 同一个覆盖增强需求, 对应同样的重复次数, 那么, 系统消息窗中需 要发送的系统消息的次数可能相同也可能不同,而发送系统消息的子帧位置也 可能相同, 也可能不同, 如果发送系统消息的子帧位置不同, 则对应着不同的 系统消息窗内系统消息传输配置。
比如, 以覆盖增强需求要求传输 4次系统消息为例, 则具体可以如下: 如果系统消息窗长度大于 4ms , 则系统消息窗内可以传递 4次系统消息, 那么, 可以在系统消息窗中选择出 4个子帧来传输系统消息, 比如前面 4个子帧 或最后四个子帧等; 或者, 比如消息窗长度为 40ms , 则可以规定系统消息窗 内的 4个无线帧中, 每个无线帧的 1号子帧用来发送系统消息, 并一共发送 4次 系统消息; 或者, 还可以规定 1号无线帧的 0号子帧, 2号无线帧的 3号子帧, 3 号无线帧的 5号子帧, 4号无线帧的 6号子帧用来发送系统消息, 并一共发送 4 次系统消息, 等等, 在此不再列举。
如果系统消息窗内不能传输 4次系统消息, 比如, 系统消息窗的长度为 lms 或者 2ms, 那么, 可以针对覆盖增强终端设备, 以原系统消息窗为参考, 扩展 该系统消息窗, 比如, 原系统消息窗的长度为 lms, 并且, 计算系统消息窗的 位置为 2号无线帧的 3号子帧, 那么, 可以把 2号无线帧的 3号子帧, 作为覆盖增 强扩展系统消息窗的起始子帧, 并向后扩展 3个子帧, 即把 2号无线帧的 3号、 4 号、 5号和 6号子帧作为扩展后的系统消息窗; 或者, 可以把 3号子帧作为扩展 系统消息窗的结束子帧, 即把 0号、 1号、 2号和 3号子帧作为扩展后的系统消息 窗。 当然, 3号子帧还可以作为扩展系统消息窗的中间位置, 在此不再赘述。
如果系统消息窗的窗长度不足以传输 4次系统消息, 则除了对系统消息窗 进行扩展之外,还可以分别在连续的多个系统消息窗内进行传输, 即可以分别 在连续的多个系统消息窗内传输 4次系统消息。 比如, 系统消息窗的长度为 2ms , 那么, 可以在第一个系统消息窗内传递 2次系统消息, 在第二个系统消 息窗内传递 2次系统消息。
即使系统消息窗可以传递 4次系统消息,也可以对原系统消息窗进行扩展, 以用来传输系统消息; 或者, 也可以把 4次系统消息分散在连续的多个系统消 息窗内进行传递, 在此不再赘述。
此外,如果系统消息要求的传输次数大于等于系统消息窗的窗长度, 则可 以在系统消息窗的每个可用子帧都传递系统消息。
( 2 )通过调整终端设备尝试接收次数来满足覆盖增强需求, 而不需要信 息重复。
在这种情况下,可以在系统消息窗内,任意选择一个子帧来发送系统消息。 ( 3 )通过信息重复和调整终端设备尝试接收次数来满足覆盖增强需求。 同样的覆盖增强需求,可以由不同的终端设备尝试接收次数和不同信息重 复接收次数联合起来共同满足, 比如 5dB的覆盖增强需求, 可以由 3次终端设 备尝试接收, 和 6次信息重复共同来满足, 也可以由 2次终端设备接收尝试, 和 10次信息重复共同来满足, 等等。
同样的覆盖增强需求, 由于终端设备尝试接收次数配置的不同,信息重复 次数也会随着不同, 其对应的系统消息窗中的系统消息发送次数也就不同,从 而导致发送系统消息的子帧选择也不同,即对应不同的系统消息窗内系统消息 传输配置。
可选的,可以定义终端设备的尝试接收模式,并根据确定的尝试接收模式, 确定系统消息窗中系统消息的发送次数和发送子帧。 其中, 该尝试接收模式, 可以定义终端设备尝试接收的每次尝试接收的合并次数,以及尝试接收的最大 次数。
比如, 终端设备尝试接收每次合并的子帧是 4, 那么, 如果系统消息窗的 长度大于 4ms, 则可以在每个系统消息窗中选中 4个子帧来传递 4次系统消息, 每个消息接收窗终端设备累积合并, 作为一次终端设备尝试接收; 或者, 在相 邻的两个消息接收窗中分别传递两次, 相邻的两个消息接收窗的系统消息合 并, 作为一次终端设备尝试接收。
进一步的,如果需要的终端设备尝试接收次数比较多, 比如需要终端设备 尝试接收的次数为 16次, 那么, 如果仅仅使用传统系统消息窗的资源, 则终端 设备接收系统消息的时间可能比较长, 所以此时可以考虑扩展传统系统消息 窗, 扩展方式和前面所描述的系统消息窗的扩展类似, 在此不再赘述。
此外, 还可以根据确定的系统覆盖增强需求和 /或终端设备尝试接收模式, 来确定系统消息配置, 其中, 系统消息配置可以包括系统消息窗长度, 系统消 息发送周期, 和系统消息更新周期中的一个或者多个。 比如, 如果覆盖增强需 求较大, 需要的重复次数比较多, 比如 16次重复, 那么系统消息窗的长度可以 配置为 20ms或者 40ms, 等等。 或者, 如果终端设备尝试接收的次数比较多, 那么, 系统消息发送周期可以配置为较小的值, 等等。
503、 基站设备将该配置消息通知给终端设备。
例如, 具体可以以独立的消息形式通知给终端设备,也可以携带在已有的 消息中通知给终端设备, 在此不再赘述。
504、 基站设备在该配置信息所指示的资源上对系统消息进行传输。
即, 根据系统消息窗的窗长度、 系统消息的周期、 系统消息更新周期、 传 输系统消息时使用的子帧信息和 /或系统消息窗内系统消息的传输次数等对系 统消息进行传输。
505、 终端设备接收配置信息, 并在该配置消息所指示的资源上接收基站 设备发送的系统消息。
此后, 终端设备还可以对该接收到的系统消息进行处理, 比如, 进行接收 合并以及接收尝试等操作。
由上可知, 本实施例采用由基站设备来确定配置信息, 其中, 该配置信息 指示系统消息窗内的系统消息传输配置, 并将该配置信息通知给终端设备, 然 后根据该配置信息对系统消息进行传输, 这样, 终端设备就可以根据该配置信 息接收基站设备发送的系统消息。 由于在该方案中, 可以通过通知的方式, 让 终端设备确切知道系统消息窗内的系统消息传输配置, 所以,有利于后续终端 设备进行接收合并以及接收尝试等操作, 可以降低终端设备的处理复杂度,提 高覆盖增强的效果。 实施例七、

需说明的是,不同的系统消息可以有不同的系统消息窗内的系统消息传输 配置,也可以有相同的系统消息窗内的系统消息传输配置; 相同的系统消息可 以有不同的系统消息窗内的系统消息传输配置,也可以有相同的系统消息窗内 的系统消息传输配置,比如,同样需要在一个系统消息窗内传输两次系统消息, 那么, 如果系统消息窗的窗长度为 10毫秒(ms, millisecond) , 那么, 就可以 从这 10ms长的 10个子帧( lms也是一个子帧的长度) 中, 任意选择两个可用子 帧来传输两次系统消息。 其中, 可以通过枚举的方式, 罗列出系统消息窗中用 于系统消息传输的子帧编号。 其中, 与终端设备约定的配置规则, 可以是由用户预先分别在基站设备和 终端设备上进行设置。 例如, 具体可以如下:

其中, 覆盖增强需求信息、 覆盖增强等级信息、 重复次数要求信息、 终端 设备的尝试接收次数要求信息、系统消息配置和系统消息窗内的系统消息传输 配置之间的设置关系, 可以参见前面的实施例 (比如实施例五), 在此不再赘 述。
602、 基站设备在确定的配置信息所指示的资源上发送系统消息。

603、 终端设备按照与基站设备约定的配置规则确定配置信息, 其中, 该 配置信息用于指示系统消息窗内的系统消息传输配置。

需说明的是,不同的系统消息可以有不同的系统消息窗内的系统消息传输 配置,也可以有相同的系统消息窗内的系统消息传输配置; 相同的系统消息可 以有不同的系统消息窗内的系统消息传输配置,也可以有相同的系统消息窗内 的系统消息传输配置。
其中, 与基站设备约定的配置规则, 可以是由用户预先分别在基站设备和 终端设备上进行设置。 例如, 具体可以如下:

其中, 覆盖增强需求信息、 覆盖增强等级信息、 重复次数要求信息、 终端 设备的尝试接收次数要求信息、系统消息配置和系统消息窗内的系统消息传输 配置之间的设置关系, 可以参见前面的实施例 (比如实施例五), 在此不再赘 述。
此外,还需说明的是, 该终端设备所采用的确定配置信息的方式应保持与 基站设备所采用的方式一致。
604、 终端设备在确定的配置信息所指示的资源上接收基站设备传输的系 统消息。
此后, 终端设备还可以对该接收到的系统消息进行处理, 比如, 进行接收 合并以及接收尝试等操作。
由上可知, 本实施例采用由基站设备和终端设备预先约定配置规则, 然后 由基站设备和终端设备分别按照约定的配置规则确定当前的配置信息, 其中, 该配置信息指示系统消息窗内的系统消息传输配置,然后基站设备在该配置信 息所指示的资源上发送对系统消息,而终端设备则在该配置信息所指示的资源 上接收系统消息。 由于在该方案中, 可以通过与终端设备约定的方式, 让终端 设备确切知道系统消息窗内的系统消息传输配置, 所以,有利于后续终端设备 进行接收合并以及接收尝试等操作, 可以降低终端设备的处理复杂度,提高覆 盖增强的效果。 实施例八、

其中, 处理器 701在确定配置信息(即系统消息窗内的系统消息传输配置 ) 时, 可以采用多种方式, 例如, 具体可以如下:
( 1 )第一种方式;

其中, 信号重复(即重复次数要求信息)和"终端设备尝试接收", 作为两 种覆盖增强技术, 可以联合使用, 不同的重复次数和不同的终端设备尝试接收 次数的组合, 可以满足不同的覆盖增强需求。
具体的, 在对系统消息窗进行配置时, 也可以将覆盖增强需求、 覆盖增强 等级、 重复次数需求和 /或终端设备尝试接收次数需求也配置在其中, 例如, 可参见图 lb和图 lc, 在此不再赘述。
其中, 处理器 701在确定配置信息(即系统消息窗内的系统消息传输配置 ) 时, 可以先根据获取到的系统消息的覆盖增强需求信息、 覆盖增强等级信息、 重复次数要求信息和 /或终端设备的尝试接收次数要求信息等信息来确定系统 消息配置, 然后根据确定的系统消息配置来确定该配置信息,也可以预先设置 系统消息的覆盖增强需求信息、 覆盖增强等级信息、 重复次数要求信息和 /或 终端设备的尝试接收次数要求信息等信息和该配置信息的对应关系,然后在获 取到系统消息的覆盖增强需求信息、覆盖增强等级信息、重复次数要求信息和 /或终端设备的尝试接收次数要求信息等信息后, 通过查找该对应关系来确定 对应的配置信息; 或者, 还可以获取系统消息配置, 根据该系统消息配置、 结 合获取到的系统消息的覆盖增强需求信息、覆盖增强等级信息、重复次数要求 信息和 /或终端设备的尝试接收次数要求信息等信息来确定配置信息, 即: 处理器 701 , 具体可以用于根据获取到的系统消息的覆盖增强需求信息、 覆盖增强等级信息、 重复次数要求信息和 /或终端设备的尝试接收次数要求信 息确定系统消息配置, ^据确定的系统消息配置确定配置信息; 或者,
处理器 701 , 除了获取系统消息的覆盖增强需求信息、覆盖增强等级信息、 重复次数要求信息和 /或终端设备的尝试接收次数要求信息等信息之外, 还可 以获取系统消息配置, 然后根据获取到的系统消息配置、结合获取到的系统消 息的覆盖增强需求信息、 覆盖增强等级信息、 重复次数要求信息和 /或终端设 备的尝试接收次数要求信息等信息来确定配置信息; 或者,
处理器 701 , 具体可以用于根据获取到的系统消息的覆盖增强需求信息、 覆盖增强等级信息、 重复次数要求信息和 /或终端设备的尝试接收次数要求信 息等信息直接确定配置信息, 具体可以如下:
处理器 701 , 具体可以用于根据获取到的系统消息的覆盖增强需求信息、 覆盖增强等级信息、 重复次数要求信息和 /或终端设备的尝试接收次数要求信 息确定系统消息的传输次数(即系统消息总的传输次数), 获取系统消息窗的 窗长度, 根据该窗长度和传输次数确定传输系统消息时使用的子帧信息。
其中, 可以通过多种方式来获取系统消息窗的窗长度, 比如, 可以获取系 统消息配置, 然后从系统消息配置中提取该系统消息窗的窗长度, 等等。
其中, 子帧信息可以包括至少子帧位置, 此外, 该子帧信息还可以包括子 帧数等信息, 即该子帧信息可以指示具体用多少子帧、 以及哪些子帧来传输该 系统消息。
此外,在选择传输系统消息的子帧时, 如果系统消息窗的窗长度不足以传 输 N个系统消息, 还可以对该系统消息窗进行扩展, 以便后续可以在该扩展后 的系统消息窗中选择子帧, 以传输系统消息。 其中, N为该系统消息窗内系统 消息的传输次数, 且 N为大于 0的整数。 即:
处理器 701 , 具体可以用于在该窗长度(即系统消息窗的窗长度)足以传 输 N个系统消息时, 从系统消息窗中选择子帧, 以传输系统消息; 在该窗长度 不足以传输 N个系统消息时, 扩展系统消息窗, 从扩展后的系统消息窗中选择 子帧, 以传输系统消息。
当然, 在窗长度(即系统消息窗的窗长度)足以传输 N个系统消息时, 处 理器 701也可以扩展系统消息窗, 从扩展后的系统消息窗中选择子帧, 以传输 系统消息。
可选的,也可以不扩展系统消息窗, 而是从连续的多个系统消息窗来选择 子帧来传输系统消息, 即:
处理器 701 , 具体可以用于根据该窗长度和传输次数从确定单元连续的多 个系统消息窗中选择子帧, 以传输系统消息。
可选的,还可以根据系统消息的周期来确定是采用扩展系统消息窗的方式 还是采用利用连续的多个系统消息窗的方式, 比如, 若系统消息的周期较长, 则采用扩展系统消息窗的方式, 而如果系统消息的周期较短, 则采用利用连续 的多个系统消息窗的方式, 即具体可以如下:
处理器 701 , 具体用于获取系统消息的周期, 确定该系统消息的周期是否 超过预置周期阈值; 若超过该周期阈值, 则在确定所述窗长度足以传输 N个系 统消息时,从系统消息窗中选择子帧,以传输系统消息,或者扩展系统消息窗, 从扩展后的系统消息窗中选择子帧, 以传输系统消息; 在该窗长度不足以传输 N个系统消息 (N为系统消息的传输次数) 时, 扩展系统消息窗, 从扩展后的 系统消息窗中选择子帧, 以传输系统消息; 若未超过该周期阈值, 则根据所述 窗长度和传输次数从连续的多个系统消息窗中选择子帧, 以传输系统消息。
其中, 该周期阈值可以根据实际应用的需求进行设置, 在此不再赘述。 可选的,在需要终端设备的尝试接收次数较多时,如果仅仅使用原系统消 息窗的资源, 则终端设备接收系统消息的时间可能会比较长, 因此, 为了减少 终端设备接收系统消息的时间, 此时也可以对系统消息窗进行扩展, 即:
处理器 701 , 具体可以用于根据该终端设备的尝试接收次数要求信息确定 终端设备的尝试接收次数,在确定该尝试接收次数大于预置阈值时,扩展系统 消息窗,根据该系统消息窗的窗长度和系统消息窗内系统消息的传输次数从扩 展后的系统消息窗中选择子帧, 以传输系统消息。
当然, 由于对系统消息窗进行了扩展, 因此, 同一个系统消息窗内可以传 输的系统消息次数也会增多, 所以, 此时终端设备的尝试接收次数也可以相应 的减少。 此外, 当终端设备的尝试接收次数较多时, 可以选择较小的系统消息 周期, 在此不再赘述。
以上各个部分的具体实施可参见前面的实施例, 在此不再赘述。
由上可知, 本实施例的基站设备可以确定配置信息, 其中, 该配置信息用 于指示系统消息窗内的系统消息传输配置,然后在该配置信息所指示的资源上 发送系统消息,以便终端设备根据该配置信息接收系统消息。由于在该方案中, 可以让终端设备确切知道系统消息窗内的系统消息传输配置, 所以,有利于后 续终端设备进行接收合并以及接收尝试等操作,可以降低终端设备的处理复杂 度, 提高覆盖增强的效果。 实施例九、

其中,如果该配置信息是按照与基站设备约定的配置规则来确定的话, 则 该终端设备所采用的确定方式应保持与基站设备所采用的方式一致, 其中, 处 理器 801在确定配置信息 (即系统消息窗内的系统消息传输配置) 时, 可以采 用以下任意一种方式(只需与基站设备保持一致即可), 例如, 具体可以如下: ( 1 )第一种方式;
可以先获取系统消息配置,然后根据系统消息配置来确定该配置信息,即: 处理器 801 , 具体可以用于获取系统消息配置, 根据获取的系统消息配置 确定配置信息。
例如, 可以先定义系统消息配置和配置信息(即系统消息传输配置)之间 的对应关系, 然后, 在获取到系统消息配置之后, 通过查询该对应关系, 便可 以得到对应的配置信息 (即系统消息传输配置)。
上述系统消息配置和配置信息 (即系统消息传输配置)之间的对应关系, 可以由网络侧设备和终端设备根据一定的配置规则确定的,也可以由网络侧设 备确定, 并通知给终端设备, 比如, 可以由网络侧设备确定一个用于记录 "系 统消息配置和配置信息 (即系统消息传输配置)之间的对应关系 "的映射表, 然后将该映射表通知给终端设备, 等等。
其中, 该系统消息配置可以包括系统消息窗的窗长度( si-WindowLength ) 的配置和系统消息的周期 (si-Periodicity ) 的配置等, 此外, 该系统消息配置 还可以包括系统消息更新周期等。 例如, 其中, 系统消息窗的窗长度可以是 ( msl, ms2, ms5, mslO, msl5, ms20,ms40 )等,而系统消息窗的周期可以是( rf8, rfl6, rf32, rf64, rfl28, rf256, rf512 )等, 其中, rf指的是无线帧( Radio Frame )。
需说明的是, 不同的系统消息可以有不同的系统消息配置,也可以有相同 的系统消息配置;同一个系统消息的系统消息配置也可以 ^据实际应用的需求 进行调整的,即基站可以根据需求选择合适的系统消息窗的窗长度和系统消息 的周期, 组成系统消息配置。
( 2 )第二种方式;
具体可以先获取系统消息的覆盖增强需求信息、覆盖增强等级信息、重复 次数要求信息和 /或终端设备的尝试接收次数要求信息等信息, 然后根据获取 到的系统消息的覆盖增强需求信息、覆盖增强等级信息、重复次数要求信息和 /或终端设备的尝试接收次数要求信息等信息来系统消息窗内的系统消息传输 配置, 即:
处理器 801 , 具体可以用于获取系统消息的覆盖增强需求信息、 覆盖增强 等级信息、 重复次数要求信息和 /或终端设备的尝试接收次数要求信息等信息; 根据获取到的系统消息的覆盖增强需求信息、覆盖增强等级信息、重复次数要 求信息和 /或终端设备的尝试接收次数要求信息确定配置信息。
上述各种需求信息(即系统消息的覆盖增强需求信息、覆盖增强等级信息、 重复次数要求信息和 /或终端设备的尝试接收次数要求信息等信息 )和配置信 息 (即系统消息传输配置)之间的对应关系, 可以由网络侧设备和终端设备根 据一定的配置规则确定的, 也可以由网络侧设备确定, 并通知给终端设备, 比 如, 可以由网络侧设备确定一个用于记录 "需求信息(即系统消息的覆盖增强 需求信息、 覆盖增强等级信息、 重复次数要求信息和 /或终端设备的尝试接收 次数要求信息等信息)和配置信息(即系统消息传输配置)之间的对应关系 "的 映射表, 然后将该映射表通知给终端设备, 等等。
另外, 需说明的是, 系统消息的覆盖增强需求信息、 覆盖增强等级信息、 重复次数要求信息和 /或终端设备的尝试接收次数要求信息等信息的设置可以 采用多种策略, 比如, 系统消息的覆盖增强需求信息、 覆盖增强等级信息、 重 复次数要求信息和 /或终端设备的尝试接收次数要求信息等信息, 可以是专门 为系统消息而设置的。 或者, 也可以设置终端设备的覆盖增强等级, 根据终端 设备的覆盖增强等级确定系统消息的覆盖增强等级,然后再根据系统消息的覆 盖增强等级来确定这些信息(即系统消息的覆盖增强需求信息、覆盖增强等级 信息、重复次数要求信息和 /或终端设备的尝试接收次数要求信息等信息),在 此不再赘述。
其中, 系统消息的覆盖增强需求信息、 覆盖增强等级信息、 重复次数要求 信息和 /或终端设备的尝试接收次数要求信息等的具体说明可以参见实施例 一, 在此不再赘述。
其中, 信号重复和"终端设备尝试接收", 作为两种覆盖增强技术, 可以联 合使用, 不同的重复次数和不同的终端设备尝试接收次数的组合, 可以满足不 同的覆盖增强需求。
具体的, 在对系统消息窗进行配置时, 也可以将覆盖增强需求、 覆盖增强 等级、 重复次数需求和 /或终端设备尝试接收次数需求也配置在其中, 例如, 参见图 lb和图 lc , 在此不再赘述。
其中, 处理器 801在确定配置信息(即系统消息窗内的系统消息传输配置 ) 时, 可以先根据获取到的系统消息的覆盖增强需求信息、 覆盖增强等级信息、 重复次数要求信息和 /或终端设备的尝试接收次数要求信息等信息来确定系统 消息配置, 然后 ^据确定的系统消息配置来确定该配置信息(即系统消息窗内 的系统消息传输配置), 也可以预先设置系统消息的覆盖增强需求信息、 覆盖 增强等级信息、 重复次数要求信息和 /或终端设备的尝试接收次数要求信息等 信息和该配置信息的对应关系, 然后在获取到系统消息的覆盖增强需求信息、 覆盖增强等级信息、 重复次数要求信息和 /或终端设备的尝试接收次数要求信 息等信息后, 通过查找该对应关系来确定对应的配置信息; 或者, 还可以获取 系统消息配置,根据该系统消息配置、 结合获取到的系统消息的覆盖增强需求 信息、 覆盖增强等级信息、 重复次数要求信息和 /或终端设备的尝试接收次数 要求信息等信息来确定配置信息, 即:
处理器 801 , 具体可以用于根据获取到的系统消息的覆盖增强需求信息、 覆盖增强等级信息、 重复次数要求信息和 /或终端设备的尝试接收次数要求信 息确定系统消息配置, ^据确定的系统消息确定配置信息。 或者,
处理器 801 , 除了获取系统消息的覆盖增强需求信息、覆盖增强等级信息、 重复次数要求信息和 /或终端设备的尝试接收次数要求信息等信息之外, 还可 以获取系统消息配置, 然后根据获取到的系统消息配置、结合获取到的系统消 息的覆盖增强需求信息、 覆盖增强等级信息、 重复次数要求信息和 /或终端设 备的尝试接收次数要求信息等信息来确定配置信息; 或者,
处理器 801 , 具体可以用于根据获取到的系统消息的覆盖增强需求信息、 覆盖增强等级信息、 重复次数要求信息和 /或终端设备的尝试接收次数要求信 息等信息直接确定配置信息, 具体可以如下:
处理器 801 , 具体可以用于根据获取到的系统消息的覆盖增强需求信息、 覆盖增强等级信息、 重复次数要求信息和 /或终端设备的尝试接收次数要求信 息确定系统消息的传输次数(即系统消息总的传输次数); 获取系统消息窗的 窗长度;根据该窗长度和传输次数确定基站设备传输系统消息时使用的子帧信 息。
其中, 可以通过多种方式来获取系统消息窗的窗长度, 比如, 可以获取系 统消息配置, 然后从系统消息配置中提取该系统消息窗的窗长度, 等等。
其中, 子帧信息可以包括至少子帧位置, 此外, 该子帧信息还可以包括子 帧数等信息, 即该子帧信息可以指示具体用多少子帧、 以及哪些子帧来传输该 系统消息。
此外,在选择传输系统消息的子帧时, 如果系统消息窗的窗长度不足以传 输 N个系统消息, 还可以对该系统消息窗进行扩展, 以便后续可以在该扩展后 的系统消息窗中选择子帧, 以接收基站设备发送的系统消息。 其中, N为该系 统消息窗内系统消息的传输次数, 且 N为大于 0的整数。 即:
处理器 801 , 具体可以用于在该窗长度足以传输 N个系统消息时, 从系统 消息窗中选择子帧, 以接收基站设备发送的系统消息, 其中, N为系统消息的 传输次数; 在该窗长度不足以传输 N个系统消息时, 扩展系统消息窗, 从扩展 后的系统消息窗中选择子帧, 以接收基站设备发送的系统消息。
当然, 在窗长度(即系统消息窗的窗长度)足以传输 N个系统消息时, 处 理器 801也可以扩展系统消息窗, 从扩展后的系统消息窗中选择子帧, 以接收 基站设备发送的系统消息。
可选的,也可以不扩展系统消息窗, 而是从连续的多个系统消息窗来选择 子帧来传输系统消息, 即:
处理器 801 , 具体可以用于根据该窗长度和传输次数从连续的多个系统消 息窗中选择子帧, 以接收基站设备发送的系统消息。
可选的,还可以根据系统消息的周期来确定是采用扩展系统消息窗的方式 还是采用利用连续的多个系统消息窗的方式, 比如, 若系统消息的周期较长, 则采用扩展系统消息窗的方式, 而如果系统消息的周期较短, 则采用利用连续 的多个系统消息窗的方式, 即:
处理器 801 , 具体可以用于获取系统消息的周期; 确定该系统消息的周期 是否超过预置周期阈值; 若超过该周期阈值, 则在确定该窗长度足以传输 N个 系统消息时, 从系统消息窗中选择子帧, 以接收基站设备发送的系统消息, 或 者扩展系统消息窗,从扩展后的系统消息窗中选择子帧, 以接收基站设备发送 的系统消息; 在该窗长度不足以传输 N个系统消息时, 扩展系统消息窗, 从扩 展后的系统消息窗中选择子帧, 以接收基站设备发送的系统消息; 若未超过所 述周期阈值, 则根据该窗长度和传输次数从连续的多个系统消息窗中选择子 帧, 以接收基站设备发送的系统消息。
其中, 该周期阈值可以根据实际应用的需求进行设置, 在此不再赘述。 可选的,在需要终端设备的尝试接收次数较多时,如果仅仅使用原系统消 息窗的资源, 则终端设备接收系统消息的时间可能会比较长, 因此, 为了减少 终端设备接收系统消息的时间, 此时也可以对系统消息窗进行扩展, 即:
处理器 801 , 具体用于根据该终端设备的尝试接收次数要求信息确定终端 设备的尝试接收次数,确定该尝试接收次数大于预置阈值时,扩展系统消息窗; 根据该窗长度和传输次数从扩展后的系统消息窗中选择子帧,以接收基站设备 发送的系统消息。
当然, 由于对系统消息窗进行了扩展, 因此, 同一个系统消息窗内可以传 输的系统消息次数也会增多, 所以, 此时终端设备的尝试接收次数也可以相应 的减少。 此外, 当终端设备的尝试接收次数较多时, 可以选择较小的系统消息 周期, 在此不再赘述。
该终端设备具体可以手机、 平板电脑或个人计算机等设备。
以上各个部分的具体实施可参见前面的实施例, 在此不再赘述。
由上可知, 本实施例的终端设备可以确定配置信息, 其中, 该配置信息用 于指示系统消息窗内的系统消息传输配置,然后在该配置信息所指示的资源上 接收基站设备发送的系统消息。 由于在该方案中, 终端设备可以确切知道系统 消息窗内的系统消息传输配置, 所以,有利于后续终端设备进行接收合并以及 接收尝试等操作, 可以降低终端设备的处理复杂度, 提高覆盖增强的效果。 本领域普通技术人员可以理解上述实施例的各种方法中的全部或部分步 骤是可以通过程序来指令相关的硬件来完成,该程序可以存储于一计算机可读 存储介质中, 存储介质可以包括: 只读存储器(ROM, Read Only Memory ), 随机存取记忆体(RAM, Random Access Memory ) , 磁盘或光盘等。 以上对本发明实施例所提供的一种系统消息的覆盖增强传输装置、系统和 了阐述, 以上实施例的说明只是用于帮助理解本发明的方法及其核心思想; 同 时, 对于本领域的技术人员, 依据本发明的思想, 在具体实施方式及应用范围 上均会有改变之处, 综上所述, 本说明书内容不应理解为对本发明的限制。
