Description

一种信号传输方法、 用户设备及基站 技术领域 本发明实施例涉及通信技术领域, 尤其涉及一种信号传输方法、用户设备 及基站。 背景技术
在长期演进( Long Term Evolution, LTE )或高级长期演进( LTE Advanced, LTE-A ) 系统中, 通常在不同时刻, 用户设备 ( User Equipment, UE ) 的特征 参量是不同的。 这里, UE的特征参量指的是: 用来度量 UE与基站之间的通 信质量的值或信息,和 /或用来度量 UE与基站之间的信道质量的值或信息, 和 /或用来反映 UE的业务特征的信息。
例如, 某一时刻 UE和基站通信时, 信道状况较差, UE和基站之间进行 信号传输需要较大的覆盖增强,此时可以通过更多的资源开销来提高业务传输 的可靠性; 而在信道状况较好的时候, UE和基站之间进行信号传输需要较小 的覆盖增强,此时可以通过较小的资源开销就可以进行可靠的业务传输。但是, 现有技术中, 例如在对 UE和基站之间的信号传输进行覆盖增强时, 就不会考 虑当前的覆盖增强值, 而是采用统一的覆盖增强技术进行覆盖增强, 另外, 在 覆盖增强时, UE或基站可支持传输的信号相同, 支持信号的功能也相同。

请参阅图 1 , 图 1示出了本发明中 UE的一个实施例, 本实施例的 UE 100 包括:
第一确定单元 101 , 用于确定 UE的特征参量, UE的特征参量指的是: 用来度量 UE的通信质量的值或信息,和 /或用来度量 UE的信道质量的值或信 息, 和 /或用来反映 UE的业务特征的信息;
第一处理单元 102, 用于根据 UE的特征参量及预设的对应关系确定 UE 传输第一信号所用的覆盖增强技术, 和 /或确定 UE支持传输的第二信号, 和 / 或确定 UE支持的第三信号的功能。
为便于理解, 下面以一个实际应用场景对本实施例中的 UE 100的各单元 之间的交互方式进行描述:
首先, 第一确定单元 101确定 UE的特征参量, UE的特征参量指的是用 来度量 UE的通信质量的值或信息,和 /或用来度量 UE的信道质量的值或信息, 和 /或用来反映 UE的业务特征的信息。
具体的, UE的特征参量可包括以下至少一种: 资源、 资源索引、 级别、 级别索引、 增强级别、 增强级别索引、 重复级别、 重复级别索引、 重复次数、 重复次数索引、 覆盖增强值、 覆盖增强范围的索引、 路径损耗值、 路径损耗范 围的索引、 参考信号接收功率值、 参考信号接收功率范围的索引、 参考信号接 收质量值、 参考信号接收质量范围的索引、 信道质量信息值、 信道质量信息范 围的索引、业务类型、业务类型的索引、功率节省需求、功率节省需求的索引、 时延需求、 时延需求的索引、检测预先规定的信道的次数、检测预先规定的信 道次数的索引、 移动性需求、 移动性需求的索引。
第一确定单元 101可以根据接收到的指示 UE的特征参量的信令确定 UE 的特征参量, 这个信令可以是其他 UE发送给本实施例的 UE的, 也可以是基 站或其他网络实体发送给 UE的; 或第一确定单元 101根据是否能正确接收下 行信号确定 UE的特征参量, 例如, UE向基站发送一个上行信号, 如果 UE 能够正确接收到基站反馈的对应的下行信号, 则第一确定单元 101 即可确定 UE当前的特征参量(如表示当前通信质量的特征参量); 更具体地, 当特征参 量是增强级别索引(或重复级别索引, 或重复级别, 或增强级别), 所述上行信 号是物理随机接入信道 PRACH, 所述下行信号是随机接入响应时, UE若按 照增强级别索引(或重复级别索引, 或重复级别, 或增强级别) X对应的 PRACH 重复次数 r在所述增强级别索引(或重复级别索引, 或重复级别, 或增强级别) X 所对应的 PRACH资源(时间资源, 和 /或频率资源, 和 /或码字资源)上重复 r次 发送 PRACH后, 成功收到随机接入响应或成功完成随机接入过程, 则该 UE 确定自己的特征参量是增强级别索引(或重复级别索引, 或重复级别, 或增强 级别) X; 或第一确定单元 101通过对接收到的下行信号进行测量确定 UE的特 征参量; 具体地, UE可以通过测量参考信号, 或同步信号, 或物理广播信道 来确定该 UE的特征参量; 或第一确定单元 101 自行确定 UE的特征参量。
当第一确定单元 101确定 UE的特征参量之后, 第一处理单元 102根据 UE的特征参量及预设的对应关系确定 UE传输第一信号所用的覆盖增强技术, 和 /或确定 UE支持传输的第二信号, 和 /或确定 UE支持的第三信号的功能。
本实施例中,预设的对应关系可以为预设的函数关系,或预设的表格关系, 或预设的规定关系,预设的对应关系可由基站通过信令预先配置,也可以由系 统通过标准协议预先设置。
预设的对应关系指的是预设的特征参量与传输第一信号所用的覆盖增强 技术的对应关系,及预设的特征参量与支持传输的第二信号的对应关系,及预 设的特征参量与支持的第三信号的功能的对应关系。
具体地,预设的特征参量与传输第一信号所用的覆盖增强技术的对应关系 可以为: 若特征参量小于或等于特征参量阀值, 则 UE采用第一覆盖增强技术 传输第一信号, 若特征参量大于特征参量阀值, 则 UE采用第二覆盖增强技术 传输第一信号, 其中, 第一覆盖增强技术和第二覆盖增强技术均是用于提高信 号传输可靠性的技术, 二者的主要区别在于: 可实现的覆盖增强强度不同; 预设的特征参量与支持传输的第二信号的对应关系可以为:若特征参量小 于或等于特征参量阀值, 则 UE支持传输信号集合一中的第二信号, 若特征参 量大于特征参量阀值, 则 UE支持传输信号集合二中的第二信号, 其中, 信号 集合一中的第二信号与信号集合二中的第二信号不同,这里的不同主要指的是 信号集合一包含的第二信号的类型与信号集合二包含的第二信号的类型不同, 但信号集合一包含的第二信号的数量可以与信号集合二包含的第二信号的数 量相同, 也可以不同;
预设的特征参量与支持的第三信号的功能的对应关系可以为:若特征参量 小于或等于特征参量阀值,则 UE支持使用第三信号的第一功能集合中的功能, 若特征参量大于所述特征参量阀值, 则 UE支持使用第三信号的第二功能集合 中的功能,其中,第一功能集合中的功能与第二功能集合中的功能不完全相同。
另外,预设的特征参量与传输第一信号所用的覆盖增强技术的对应关系也 可以为: 若特征参量属于第一特征参量集合, 则 UE采用第一覆盖增强技术传 输第一信号, 若特征参量属于第二特征参量集合, 则 UE采用第二覆盖增强技 术传输第一信号, 其中, 第一覆盖增强技术和第二覆盖增强技术均是用于提高 信号传输可靠性技术, 二者的主要区别在于: 可实现的覆盖增强强度不同; 预设的特征参量与支持传输的第二信号的对应关系也可以为:若特征参量 属于第一特征参量集合, 则 UE支持传输信号集合一中的第二信号, 若特征参 量属于第二特征参量集合, 则 UE支持传输信号集合二中的第二信号, 其中, 信号集合一中的第二信号与信号集合二中的第二信号不同,这里的不同主要指 的是信号集合一包含的第二信号的类型与信号集合二包含的第二信号的类型 不同,但信号集合一包含的第二信号的数量可以与信号集合二包含的第二信号 的数量相同, 也可以不同;
预设的特征参量与支持的第三信号的功能的对应关系也可以为:若特征参 量属于第一特征参量集合, 则 UE支持第三信号的第一功能集合中的功能, 若 特征参量属于第二特征参量集合, 则 UE支持使用第三信号的第二功能集合中 的功能, 其中, 第一功能集合中的功能与第二功能集合中的功能不完全相同。
上述特征参量阀值、 信号集合一、 信号集合二、 第一功能集合、 第二功能 集合、 第一特征参量集合和第二特征参量集合可以由基站通过信令预先配置, 也可以由系统通过标准协议预先设置。
如,信号集合二包括的信号种类小于信号集合一包括的信号种类。信号集 合一或信号集合二可以是空集合。信号集合一中的信号可以与信号集合二中的 信号完全不同, 此时若 UE支持信号集合二中的信号也表示 UE不支持信号集 合一中的信号。信号集合一或信号集合二包括以下信号中的一种或多种: 物理 下行控制信道、 增强物理下行控制信道、 物理随机接入信道、 物理控制格式指 示信道、 物理混合自动重传请求指示信道、 单播的物理下行共享信道、 广播或 组播的物理下行共享信道、物理上行共享信道、物理上行控制信道、同步信道、 物理广播信道、 公共参考信号、 解调参考信号、 专有参考信号、 随机接入响应 消息、 随机接入响应应答消息、 竟争解决消息、 系统信息和寻呼消息。
此外,第一功能集合中的功能包括的功能个数多于第二功能集合中的功能 包括的功能个数。 具体地, 如第三信号是 PUCCH, 第一功能集合和第二功能 集合包括上报信道质量信息功能,调度请求功能,是否正确接收到信号的应答 反馈功能中的一种或多种功能,但第二功能集合中包括的功能个数小于第一功 能集合中包括的功能个数。
当第一确定单元 101确定 UE的特征参量之后, 第一处理单元 102可以根 据预设的特征参量与传输第一信号所用的覆盖增强技术的对应关系确定 UE的 特征参量对应的传输第一信号所用的覆盖增强技术;
和 /或第一处理单元 102根据预设的特征参量与支持传输的第二信号的对 应关系确定 UE的特征参量对应的支持传输的第二信号;
和 /或第一处理单元 102根据预设的特征参量与支持的第三信号的功能的 对应关系确定 UE的特征参量对应的支持的第三信号的功能。
这里的第一信号、 第二信号、 第三信号可以相同, 也可以不同。 即, 第一 信号与第二信号可以相同, 也可以不同, 第一信号与第三信号可以相同, 也可 以不同, 第二信号和第三信号可以相同, 也可以不同。
第一信号、 或第二信号、 或第三信号包括以下至少一种:
物理下行控制信道、 增强物理下行控制信道、 物理随机接入信道、 物理控 制格式指示信道、物理混合自动重传请求指示信道、单播的物理下行共享信道、 广播或组播的物理下行共享信道、 物理上行共享信道、 物理上行控制信道、 同 步信道、 物理广播信道、 公共参考信号、 解调参考信号、 专有参考信号、 随机 接入响应消息、随机接入响应应答消息、竟争解决消息、系统信息和寻呼消息。
本实施例中的传输指的是发送或接收。 下面以 UE的特征参量为覆盖增强值为例说明 UE根据 UE的特征参量及 预设的对应关系确定 UE传输第一信号所用的覆盖增强技术,和 /或确定 UE支 持传输的第二信号, 和 /或确定 UE支持的第三信号的功能。
例如,基站或系统预先规定特征参量与传输第一信号所用的覆盖增强技术 的对应关系为: 覆盖增强值为 X dB (或大于 OdB小于等于 XdB)时, 采用第一覆 盖增强技术传输第一信号;覆盖增强值为 YdB (或大于 X dB, 或大于 XdB小于 等于 YdB)时, 采用第二覆盖增强技术传输第一信号。 这里, X和 /或 Y是预定 义的特征阀值。
若第一确定单元 101确定该 UE的覆盖增强值为 X dB (或大于 OdB小于等 于 XdB), 则第一处理单元 102根据特征参量与传输第一信号所用的覆盖增强 技术的对应关系,确定采用第一覆盖增强技术传输第一信号; 而若第一确定单 元 101确定该 UE的覆盖增强值为 YdB (或大于 X dB,或大于 XdB小于等于 YdB), 则第一处理单元 102根据特征参量与传输第一信号所用的覆盖增强技 术的对应关系, 确定采用第二覆盖增强技术传输第一信号。
在本实施例中,第一覆盖增强技术及第二覆盖增强技术可以是以下技术中 的一种, 也可以下技术中的多种的组合: 重复传输、 扩频传输、 低码率传输、 捆绑传输时间间隔 (ΤΉ bundling)传输、 功率增加 (power boosting)、 功率谱密 度增加 (PSD boosting), 不断尝试 (keep trying), 放松需求、 跳频或最大似然检 测。
更具体地, 如第一信号是物理上行控制信道 PUCCH,基站或系统预先规 定: 覆盖增强值大于 O dB小于等于 X dB时, 采用放松需求 (和 /或跳频)来进行 PUCCH覆盖增强;覆盖增强值大于 X dB小于等于 YdB (或大于 X dB)时, 采 用放松需求 (和 /或跳频)和重复发送来进行 PUCCH覆盖增强。 这里 X和 /或 Y 是预定义的特征参量阀值。 如, 预先规定 X=5, Y=10。 若第一确定单元 101确 定的覆盖增强值是 3 dB, 即覆盖增强值小于 5 dB, 因此第一处理单元 102确 定 PUCCH采用放松需求 (和 /或跳频)来进行 PUCCH覆盖增强。 若第一确定单 元 101确定的覆盖增强值是 8 dB, 即覆盖增强值大于 5 dB小于 10 dB (或大于 5 dB),则第一处理单元 102确定 PUCCH采用放松需求 (和 /或跳频)和重复发送 来进行 PUCCH覆盖增强。
具体地, 再如, 第一信号是物理广播信道 PBCH,基站或系统预先规定: 覆盖增强值为 C dB时, 采用不断尝试来进行 PBCH覆盖增强; 覆盖增强值为 D dB时, 采用不断尝试和重复传输来进行 PBCH覆盖增强。这里 C和 /或 D是预 定义的特征参量阀值。 如, 预先规定 C=10, D=15。 若第一确定单元 101确定 覆盖增强值是 10 dB, 则第一处理单元 102确定 PBCH采用不断尝试来进行 PBCH覆盖增强,第一处理单元 102采用不断尝试 PBCH的检测来检测 PBCH; 若第一确定单元 101确定覆盖增强值是 15 dB,则第一处理单元 102确定 PBCH 采用不断尝试和重复传输来进行 PBCH覆盖增强,第一处理单元 102采用不断 尝试重复 PBCH的检测来检测 PBCH。
例如,基站或系统预先规定特征参量与支持传输的第二信号的对应关系为: 覆盖增强值为 X dB (或大于 OdB小于等于 XdB)时, UE支持传输信号集合一中 的第二信号; 覆盖增强值为 YdB (或大于 X dB,或大于 XdB小于等于 YdB)时, UE支持传输信号集合二中的第二信号。这里, X和 /或 Y是预定义的特征阀值。
若第一确定单元 101确定该 UE的覆盖增强值为 X dB (或大于 OdB小于等 于 XdB), 则第一处理单元 102根据特征参量与支持传输的第二信号的对应关 系, 确定支持传输信号集合一中的第二信号; 而若第一确定单元 101 确定该 UE的覆盖增强值为 YdB (或大于 X dB,或大于 XdB小于等于 YdB), 则第一处 理单元 102根据特征参量与支持传输的第二信号的对应关系,确定支持传输信 号集合二中的第二信号。
更具体地,如传输信号集合一中的第二信号是 PBCH和物理混合自动重发 请求指示信道 PHICH,传输信号集合二中的第二信号是 PBCH。基站或系统预 先规定: 覆盖增强值大于 O dB小于等于 X dB时, 支持传输信号集合一中的第 二信号;覆盖增强值大于 X dB小于等于 YdB (或大于 X dB)时, 支持传输信号 集合二中的第二信号。 这里 X和 /或 Y是预定义的特征参量阀值。 如, 预先规 定 X=5, Y=10。 若第一确定单元 101确定的覆盖增强值是 3 dB, 即覆盖增强值 小于 5 dB, 因此第一处理单元 102确定可以支持 PBCH和 PHICH。 若第一确 定单元 101确定的覆盖增强值是 8 dB, 即覆盖增强值大于 5 dB小于 10 dB, 则第一处理单元 102 确定支持 PBCH, 也即第一处理单元 102 确定不支持 PHICH。
具体地, 再如, 传输信号集合一中的第二信号是 PUCCH (或 PHICH), 传 输信号集合二中的第二信号是空信号, 即传输信号集合二中不包括任何信号。 基站或系统预先规定: 覆盖增强值大于 0 dB小于等于 X dB时, 支持传输信号 集合一中的第二信号;覆盖增强值大于 X dB小于等于 YdB (或大于 X dB)时, 支持传输信号集合二中的第二信号。这里 X和 /或 Y是预定义的特征参量阀值。 如, 预先规定 X=5, Y=10。 若 UE1的覆盖增强值是 3 dB, 则 UE1确定自己的 覆盖增强值小于 5 dB, 因此 UE1确定可以支持 PUCCH (或 PHICH)。 若 UE1 的覆盖增强值是 8 dB,则 UE1确定自己的覆盖增强值大于 5 dB小于 10 dB (或 大于 5 dB), 则 UE1确定不支持传输信号集合一中的信号, 也即 UE2确定不 支持 PUCCH (或 PHICH)。
例如,基站或系统预先规定特征参量与支持的第三信号的功能的对应关系 为: 覆盖增强值为 X dB (或大于 OdB小于等于 XdB)时, UE支持第三信号的第 一功能集合中的功能; 覆盖增强值为 YdB (或大于 X dB, 或大于 XdB小于等 于 YdB)时,UE支持第三信号的第二功能集合中的功能。这里, X和 /或 Y是预 定义的特征阀值。
若第一确定单元 101确定该 UE的覆盖增强值为 X dB (或大于 OdB小于等 于 XdB), 则第一处理单元 102根据特征参量与支持的第三信号的功能的对应 关系, 确定支持第三信号的第一功能集合中的功能; 而若第一确定单元 101 确定该 UE的覆盖增强值为 YdB (或大于 X dB, 或大于 XdB小于等于 YdB), 则第一处理单元 102根据特征参量与支持的第三信号的功能的对应关系,确定 支持第三信号的第二功能集合中的功能。
更具体地, 如第三信号是 PUCCH。 基站或系统预先规定: PUCCH 的第 一功能集合中的功能包括上报信道质量信息功能,调度请求功能,是否正确接 收到信号的应答反馈功能; PUCCH的第二功能集合中的功能包括调度请求功 能, 是否正确接收到信号的应答反馈功能。 并且, 基站或系统预先规定: 覆盖 增强值大于 0 dB小于等于 X dB时, 支持第三信号的第一功能集合中的功能; 覆盖增强值大于 X dB小于等于 YdB (或大于 X dB)时, 支持第三信号的第二功 能集合中的功能。 这里 X和 /或 Y是预定义的特征参量阀值。 如, 预先规定 X=5, Y=10。 若第一确定单元 101的覆盖增强值是 3 dB, 即覆盖增强值小于 5 dB, 因此第一处理单元 102确定可以支持 PUCCH的上报信道质量信息功能, 调度请求功能, 是否正确接收到信号的应答反馈功能。 若第一确定单元 101 确定的覆盖增强值是 8 dB, 即覆盖增强值大于 5 dB小于 10 dB (或大于 5dB), 则第一处理单元 102确定支持 PUCCH的调度请求功能,是否正确接收到信号 的应答反馈功能。
需要说明的是上述对本实施例方法实施的描述是针对特征参量是覆盖增 强值时为例说明, 当特征参量是级别、 级别索引、 重复次数、 重复次数索引、 资源、 资源索引、 增强级别、 增强级别索引、 或其它 (反映通信质量、 信道质 量、 或业务特征的)信息时, 可以类似地按照上述描述进行本实施例的实施, 这里不再赘述。
本实施例中,第一处理单元可以根据自身当前的特征参量及预设的对应关 系, 自适应地确定与基站之间传输第一信号所用的覆盖增强技术, 和 /或支持 与基站之间进行传输的第二信号, 和 /或支持的第三信号的功能, 从而去适应 不同的特征参量, 以优化系统的资源利用, 降低处理复杂度, 节省功率消耗。
下面介绍本发明实施例提供的基站, 请参阅图 2, 本实施例的基站 200包 括:
第二确定单元 201 , 用于确定 UE的特征参量, UE的特征参量指的是: 用来度量 UE的通信质量的值或信息,和 /或用来度量 UE的信道质量的值或信 息, 和 /或用来反映 UE的业务特征的信息;

为便于理解,下面以一个实际应用场景对本实施例中的基站 200的各单元 之间的交互方式进行描述:
本实施例中的 UE指的是与基站 200进行通信的一个或多个 UE。 为了筒 单起见, 下述的 UE指的是一个 UE。
首先, 第二确定单元 201确定 UE的特征参量, UE的特征参量指的是用 来度量 UE的通信质量的值或信息,和 /或用来度量 UE的信道质量的值或信息, 和 /或用来反映 UE的业务特征的信息。
具体的, UE的特征参量可包括以下至少一种: 资源、 资源索引、 级别、 级别索引、 增强级别、 增强级别索引、 重复级别、 重复级别索引、 重复次数、 重复次数索引、 覆盖增强值、 覆盖增强范围的索引、 路径损耗值、 路径损耗范 围的索引、 参考信号接收功率值、 参考信号接收功率范围的索引、 参考信号接 收质量值、 参考信号接收质量范围的索引、 信道质量信息值、 信道质量信息范 围的索引、业务类型、业务类型的索引、功率节省需求、功率节省需求的索引、 时延需求、 时延需求的索引、检测预先规定的信道的次数、检测预先规定的信 道次数的索引、 移动性需求、 移动性需求的索引。
第二确定单元 201可以根据接收到的指示 UE的特征参量的信令确定 UE 的特征参量, 这个信令可以是 UE或其他网络实体发送给基站的; 或第二确定 单元 201根据是否能正确接收上行信号确定 UE的特征参量, 例如, 基站向 UE发送一个下行信号,如果基站能够正确接收到 UE反馈的对应的上行信号, 则第二确定单元 201即可确定 UE当前的特征参量(如表示当前通信质量的特 征参量); 或第二确定单元 201通过对接收到的上行信号进行测量确定 UE的 特征参量; 或第二确定单元 201 自行确定 UE的特征参量。
当第二确定单元 201确定 UE的特征参量之后, 第二处理单元 202根据 UE 的特征参量及预设的对应关系确定基站传输第一信号所用的覆盖增强技 术, 和 /或确定基站支持传输的第二信号, 和 /或确定基站支持的第三信号的功 能。
本实施例中,预设的对应关系可以为预设的函数关系,或预设的表格关系, 或预设的规定关系,预设的对应关系可由基站通过信令预先配置,也可以由系 统通过标准协议预先设置。
预设的对应关系指的是预设的特征参量与传输第一信号所用的覆盖增强 技术的对应关系,及预设的特征参量与支持传输的第二信号的对应关系,及预 设的特征参量与支持的第三信号的功能的对应关系。
具体地,预设的特征参量与传输第一信号所用的覆盖增强技术的对应关系 可以为: 若特征参量小于或等于特征参量阀值, 则基站采用第一覆盖增强技术 传输第一信号, 若特征参量大于特征参量阀值, 则基站采用第二覆盖增强技术 传输第一信号, 其中, 第一覆盖增强技术和第二覆盖增强技术均是用于提高信 号传输可靠性的技术, 二者的主要区别在于: 可实现的覆盖增强强度不同; 预设的特征参量与支持传输的第二信号的对应关系可以为:若特征参量小 于或等于特征参量阀值, 则基站支持传输信号集合一中的第二信号, 若特征参 量大于特征参量阀值, 则基站支持传输信号集合二中的第二信号, 其中, 信号 集合一中的第二信号与信号集合二中的第二信号不同,这里的不同主要指的是 信号集合一包含的第二信号的类型与信号集合二包含的第二信号的类型不同, 但信号集合一包含的第二信号的数量可以与信号集合二包含的第二信号的数 量相同, 也可以不同;
预设的特征参量与支持的第三信号的功能的对应关系可以为:若特征参量 小于或等于特征参量阀值, 则基站支持使用第三信号的第一功能集合中的功 能, 若特征参量大于所述特征参量阀值, 则基站支持使用第三信号的第二功能 集合中的功能, 其中, 第一功能集合中的功能与第二功能集合中的功能不完全 相同。
另外,预设的特征参量与传输第一信号所用的覆盖增强技术的对应关系也 可以为: 若特征参量属于第一特征参量集合, 则基站采用第一覆盖增强技术传 输第一信号, 若特征参量属于第二特征参量集合, 则基站采用第二覆盖增强技 术传输第一信号, 其中, 第一覆盖增强技术和第二覆盖增强技术均是用于提高 信号传输可靠性技术, 二者的主要区别在于: 可实现的覆盖增强强度不同; 预设的特征参量与支持传输的第二信号的对应关系也可以为:若特征参量 属于第一特征参量集合, 则基站支持传输信号集合一中的第二信号, 若特征参 量属于第二特征参量集合, 则基站支持传输信号集合二中的第二信号, 其中, 信号集合一中的第二信号与信号集合二中的第二信号不同,这里的不同主要指 的是信号集合一包含的第二信号的类型与信号集合二包含的第二信号的类型 不同,但信号集合一包含的第二信号的数量可以与信号集合二包含的第二信号 的数量相同, 也可以不同;
预设的特征参量与支持的第三信号的功能的对应关系也可以为:若特征参 量属于第一特征参量集合, 则基站支持第三信号的第一功能集合中的功能, 若 特征参量属于第二特征参量集合,则基站支持使用第三信号的第二功能集合中 的功能, 其中, 第一功能集合中的功能与第二功能集合中的功能不完全相同。
上述特征参量阀值、 信号集合一、 信号集合二、 第一功能集合、 第二功能 集合、 第一特征参量集合和第二特征参量集合可以由基站通过信令预先配置, 也可以由系统通过标准协议预先设置。
如,信号集合二包括的信号种类小于信号集合一包括的信号种类。信号集 合一或信号集合二可以是空集合。信号集合一中的信号可以与信号集合二中的 信号完全不同,此时若基站支持信号集合二中的信号也表示基站不支持信号集 合一中的信号。信号集合一或信号集合二包括以下信号中的一种或多种: 物理 下行控制信道、 增强物理下行控制信道、 物理随机接入信道、 物理控制格式指 示信道、 物理混合自动重传请求指示信道、 单播的物理下行共享信道、 广播或 组播的物理下行共享信道、物理上行共享信道、物理上行控制信道、同步信道、 物理广播信道、 公共参考信号、 解调参考信号、 专有参考信号、 随机接入响应 消息、 随机接入响应应答消息、 竟争解决消息、 系统信息和寻呼消息。
此外,第一功能集合中的功能包括的功能个数多于第二功能集合中的功能 包括的功能个数。 具体地, 如第三信号是 PUCCH, 第一功能集合和第二功能 集合包括上报信道质量信息功能,调度请求功能,是否正确接收到信号的应答 反馈功能中的一种或多种功能,但第二功能集合中包括的功能个数小于第一功 能集合中包括的功能个数。
当第二确定单元 201确定 UE的特征参量之后, 第二处理单元 202可以根 据预设的特征参量与传输第一信号所用的覆盖增强技术的对应关系确定 UE的 特征参量对应的传输第一信号所用的覆盖增强技术;
和 /或第二处理单元 202根据预设的特征参量与支持传输的第二信号的对 应关系确定 UE的特征参量对应的支持传输的第二信号;
和 /或第二处理单元 202根据预设的特征参量与支持的第三信号的功能的 对应关系确定 UE的特征参量对应的支持的第三信号的功能。
这里的第一信号、 第二信号、 第三信号可以相同, 也可以不同。 即, 第一 信号与第二信号可以相同, 也可以不同, 第一信号与第三信号可以相同, 也可 以不同, 第二信号和第三信号可以相同, 也可以不同。

本实施例中的传输指的是发送或接收。
下面以 UE的特征参量为覆盖增强值为例说明基站根据 UE的特征参量及 预设的对应关系确定基站传输第一信号所用的覆盖增强技术, 和 /或确定基站 支持传输的第二信号, 和 /或确定基站支持的第三信号的功能。
例如,基站或系统预先规定特征参量与传输第一信号所用的覆盖增强技术 的对应关系为: 覆盖增强值为 X dB (或大于 OdB小于等于 XdB)时, 采用第一覆 盖增强技术传输第一信号;覆盖增强值为 YdB (或大于 X dB, 或大于 XdB小于 等于 YdB)时, 采用第二覆盖增强技术传输第一信号。 这里, X和 /或 Y是预定 义的特征阀值。
若第二确定单元 201确定一个 UE的覆盖增强值为 X dB (或大于 OdB小于 等于 XdB), 则第二处理单元 202根据特征参量与传输第一信号所用的覆盖增 强技术的对应关系,确定与所述 UE进行通信时采用第一覆盖增强技术传输第 一信号;而若第二确定单元 201确定该 UE的覆盖增强值为 YdB (或大于 X dB, 或大于 XdB小于等于 YdB),则第二处理单元 202根据特征参量与传输第一信 号所用的覆盖增强技术的对应关系,确定与所述 UE进行通信时采用第二覆盖 增强技术传输第一信号。
在本实施例中,第一覆盖增强技术及第二覆盖增强技术可以是以下技术中 的一种, 也可以下技术中的多种的组合: 重复传输、 扩频传输、 低码率传输、 捆绑传输时间间隔 (ΤΉ bundling)传输、 功率增加 (power boosting)、 功率谱密 度增加 (PSD boosting), 不断尝试 (keep trying), 放松需求、 跳频或最大似然检 测。
更具体地, 如第一信号是物理上行控制信道 PUCCH,基站或系统预先规 定: 覆盖增强值大于 0 dB小于等于 X dB时, 采用放松需求 (和 /或跳频)来进行 PUCCH覆盖增强;覆盖增强值大于 X dB小于等于 YdB (或大于 X dB)时, 采 用放松需求 (和 /或跳频)和重复发送来进行 PUCCH覆盖增强。 这里 X和 /或 Y 是预定义的特征参量阀值。 如, 预先规定 X=5, Y=10。 若第二确定单元 201确 定 UE1的覆盖增强值是 3 dB,即覆盖增强值小于 5 dB,因此第二处理单元 202 确定 PUCCH采用放松需求 (和 /或跳频)来进行 PUCCH覆盖增强, 第二处理单 元 202对应地按照这种方式进行 PUCCH的接收。 若第二确定单元 201确定 UE2的覆盖增强值是 8 dB,即覆盖增强值大于 5 dB小于 10 dB (或大于 5 dB), 则第二处理单元 202确定 PUCCH采用放松需求 (和 /或跳频)和重复发送来进行 PUCCH覆盖增强, 第二处理单元 202对应地按照这种方式进行 PUCCH的接 收。 具体地, 再如, 第一信号是物理广播信道 PBCH,基站或系统预先规定: 覆盖增强值不大于 C dB时, 采用不断尝试来进行 PBCH覆盖增强;覆盖增强 值为不大于 D dB时, 采用不断尝试和重复传输来进行 PBCH覆盖增强。 这里 C和 /或 D是预定义的特征参量阀值。 如, 预先规定 C=10, D=15。 若第二确定 单元 201确定当前 (一个或多个) UE的覆盖增强值不大于 10 dB,则第二处理单 元 202确定 PBCH采用不断尝试来进行 PBCH覆盖增强;若第二确定单元 201 确定当前 (一个或多个) UE的覆盖增强值不大于 15 dB,则第二确定单元 201确 定 PBCH采用不断尝试和重复传输来进行 PBCH覆盖增强。
例如,基站或系统预先规定特征参量与支持传输的第二信号的对应关系为: 覆盖增强值为 X dB (或大于 OdB小于等于 XdB)时,基站支持传输信号集合一中 的第二信号; 覆盖增强值为 YdB (或大于 X dB,或大于 XdB小于等于 YdB)时, 基站支持传输信号集合二中的第二信号。 这里, X和 /或 Y是预定义的特征阀 值。
若第二确定单元 201确定一个 UE的覆盖增强值为 X dB (或大于 OdB小于 等于 XdB), 则第二处理单元 202根据特征参量与支持传输的第二信号的对应 关系, 确定与所述 UE进行通信时支持传输信号集合一中的第二信号; 而若第 二确定单元 201确定该 UE的覆盖增强值为 YdB (或大于 X dB,或大于 XdB小 于等于 YdB), 则第二处理单元 202根据特征参量与支持传输的第二信号的对 应关系, 确定与所述 UE进行通信时支持传输信号集合二中的第二信号。
更具体地,如传输信号集合一中的第二信号是 PBCH和物理混合自动重发 请求指示信道 PHICH,传输信号集合二中的第二信号是 PBCH。基站或系统预 先规定: 覆盖增强值大于 O dB小于等于 X dB时, 支持传输信号集合一中的第 二信号;覆盖增强值大于 X dB小于等于 YdB (或大于 X dB)时, 支持传输信号 集合二中的第二信号。 这里 X和 /或 Y是预定义的特征参量阀值。 如, 预先规 定 X=5, Y=10。 若 UE1的覆盖增强值是 3 dB, 则第二确定单元 201确定 UE1 的覆盖增强值小于 5 dB, 因此第二处理单元 202确定在与 UE1通信时可以支 持 PBCH和 PHICH。 若第二确定单元 201确定 UE2的覆盖增强值是 8 dB, 即 确定 UE2的覆盖增强值大于 5 dB小于 10 dB,则第二处理单元 202确定与 UE2 进行通信时支持 PBCH, 也即与 UE2进行通信时确定不支持 PHICH。
具体地, 再如, 传输信号集合一中的第二信号是 PUCCH (或 PHICH), 传 输信号集合二中的第二信号是空信号, 即传输信号集合二中不包括任何信号。 基站或系统预先规定: 覆盖增强值大于 0 dB小于等于 X dB时, 支持传输信号 集合一中的第二信号;覆盖增强值大于 X dB小于等于 YdB (或大于 X dB)时, 支持传输信号集合二中的第二信号。这里 X和 /或 Y是预定义的特征参量阀值。 如,预先规定 X=5, Y=10。若第二确定单元 201确定 UE1的覆盖增强值是 3 dB , 即确定 UE1的覆盖增强值小于 5 dB , 因此第二处理单元 202确定与 UE1进行 通信时可以支持 PUCCH (或 PHICH)。若第二确定单元 201确定 UE1的覆盖增 强值是 8 dB , 即覆盖增强值大于 5 dB小于 10 dB (或大于 5 dB), 则第二处理 单元 202确定与 UE1进行通信时不支持传输信号集合一中的信号, 也即基站 与 UE1进行通信时不支持 PUCCH (或 PHICH)。
例如,基站或系统预先规定特征参量与支持的第三信号的功能的对应关系 为: 覆盖增强值为 X dB (或大于 OdB小于等于 XdB)时,基站支持第三信号的第 一功能集合中的功能; 覆盖增强值为 YdB (或大于 X dB,或大于 XdB小于等于 YdB)时,基站支持第三信号的第二功能集合中的功能。 这里, X和 /或 Y是预 定义的特征阀值。
若第二确定单元 201确定一个 UE的覆盖增强值为 X dB (或大于 OdB小于 等于 XdB), 则第二处理单元 202根据特征参量与支持的第三信号的功能的对 应关系, 确定支持第三信号的第一功能集合中的功能; 而若第二确定单元 201 确定所述 UE的覆盖增强值为 YdB (或大于 X dB,或大于 XdB小于等于 YdB) , 则第二处理单元 202根据特征参量与支持的第三信号的功能的对应关系,确定 支持第三信号的第二功能集合中的功能。
更具体地, 如第三信号是 PUCCH。 基站或系统预先规定: PUCCH 的第 一功能集合中的功能包括上报信道质量信息功能,调度请求功能,是否正确接 收到信号的应答反馈功能; PUCCH的第二功能集合中的功能包括调度请求功 能, 是否正确接收到信号的应答反馈功能。 并且, 基站或系统预先规定: 覆盖 增强值大于 0 dB小于等于 X dB时, 支持第三信号的第一功能集合中的功能; 覆盖增强值大于 X dB小于等于 YdB (或大于 X dB)时, 支持第三信号的第二功 能集合中的功能。 这里 X和 /或 Y是预定义的特征参量阀值。 如, 预先规定 χ=5, Υ=10。若第二确定单元 201确定 UE1的覆盖增强值是 3 dB , 即确定 UE1 的覆盖增强值小于 5 dB , 因此第二处理单元 202确定与 UE1进行通信时可以 支持 PUCCH的上报信道质量信息功能, 调度请求功能, 是否正确接收到信号 的应答反馈功能。 若第二确定单元 201确定 UE1的覆盖增强值是 8 dB, 即确 定 UE1的覆盖增强值大于 5 dB小于 10 dB (或大于 5dB),则第二处理单元 202 确定与 UE1进行通信时支持 PUCCH的调度请求功能, 是否正确接收到信号 的应答反馈功能。
需要说明的是上述对本实施例方法实施的描述是针对特征参量是覆盖增 强值时为例说明, 当特征参量是级别、 级别索引、 重复次数、 重复次数索引、 资源、 资源索引、 增强级别、 增强级别索引、 或其它 (反映通信质量、 信道质 量、 或业务特征的)信息时, 可以类似地按照上述描述进行本实施例的实施, 这里不再赘述。
本实施例中, 第二处理单元可以根据 UE当前的特征参量及预设的对应关 系, 自适应地确定与 UE之间传输第一信号所用的覆盖增强技术,和 /或支持与 UE之间进行传输的第二信号, 和 /或支持的第三信号的功能, 从而去适应不同 的 UE的特征参量, 以优化系统的资源利用, 降低处理复杂度,节省功率消耗。

为便于理解, 下面以一个实际应用场景对本实施例中的 UE 300的各单元 之间的交互方式进行描述:
在第一存储器 301里存储有预设的对应关系。本实施例中,预设的对应关 系可以为预设的函数关系, 或预设的表格关系, 或预设的规定关系, 预设的对 应关系可由基站通过信令预先配置, 也可以由系统通过标准协议预先设置。
预设的对应关系指的是预设的特征参量与传输第一信号所用的覆盖增强 技术的对应关系,及预设的特征参量与支持传输的第二信号的对应关系,及预 设的特征参量与支持的第三信号的功能的对应关系。 具体地,预设的特征参量与传输第一信号所用的覆盖增强技术的对应关系 可以为: 若特征参量小于或等于特征参量阀值, 则 UE采用第一覆盖增强技术 传输第一信号, 若特征参量大于特征参量阀值, 则 UE采用第二覆盖增强技术 传输第一信号, 其中, 第一覆盖增强技术和第二覆盖增强技术均是用于提高信 号传输可靠性的技术, 二者的主要区别在于: 可实现的覆盖增强强度不同; 预设的特征参量与支持传输的第二信号的对应关系可以为:若特征参量小 于或等于特征参量阀值, 则 UE支持传输信号集合一中的第二信号, 若特征参 量大于特征参量阀值, 则 UE支持传输信号集合二中的第二信号, 其中, 信号 集合一中的第二信号与信号集合二中的第二信号不同,这里的不同主要指的是 信号集合一包含的第二信号的类型与信号集合二包含的第二信号的类型不同, 但信号集合一包含的第二信号的数量可以与信号集合二包含的第二信号的数 量相同, 也可以不同;
预设的特征参量与支持的第三信号的功能的对应关系可以为:若特征参量 小于或等于特征参量阀值,则 UE支持使用第三信号的第一功能集合中的功能, 若特征参量大于所述特征参量阀值, 则 UE支持使用第三信号的第二功能集合 中的功能,其中,第一功能集合中的功能与第二功能集合中的功能不完全相同。
另外,预设的特征参量与传输第一信号所用的覆盖增强技术的对应关系也 可以为: 若特征参量属于第一特征参量集合, 则 UE采用第一覆盖增强技术传 输第一信号, 若特征参量属于第二特征参量集合, 则 UE采用第二覆盖增强技 术传输第一信号, 其中, 第一覆盖增强技术和第二覆盖增强技术均是用于提高 信号传输可靠性技术, 二者的主要区别在于: 可实现的覆盖增强强度不同; 预设的特征参量与支持传输的第二信号的对应关系也可以为:若特征参量 属于第一特征参量集合, 则 UE支持传输信号集合一中的第二信号, 若特征参 量属于第二特征参量集合, 则 UE支持传输信号集合二中的第二信号, 其中, 信号集合一中的第二信号与信号集合二中的第二信号不同,这里的不同主要指 的是信号集合一包含的第二信号的类型与信号集合二包含的第二信号的类型 不同,但信号集合一包含的第二信号的数量可以与信号集合二包含的第二信号 的数量相同, 也可以不同;
预设的特征参量与支持的第三信号的功能的对应关系也可以为:若特征参 量属于第一特征参量集合, 则 UE支持第三信号的第一功能集合中的功能, 若 特征参量属于第二特征参量集合, 则 UE支持使用第三信号的第二功能集合中 的功能, 其中, 第一功能集合中的功能与第二功能集合中的功能不完全相同。
上述特征参量阀值、 信号集合一、 信号集合二、 第一功能集合、 第二功能 集合、 第一特征参量集合和第二特征参量集合可以由基站通过信令预先配置, 也可以由系统通过标准协议预先设置。
如,信号集合二包括的信号种类小于信号集合一包括的信号种类。信号集 合一或信号集合二可以是空集合。信号集合一中的信号可以与信号集合二中的 信号完全不同, 此时若 UE支持信号集合二中的信号也表示 UE不支持信号集 合一中的信号。信号集合一或信号集合二包括以下信号中的一种或多种: 物理 下行控制信道、 增强物理下行控制信道、 物理随机接入信道、 物理控制格式指 示信道、 物理混合自动重传请求指示信道、 单播的物理下行共享信道、 广播或 组播的物理下行共享信道、物理上行共享信道、物理上行控制信道、同步信道、 物理广播信道、 公共参考信号、 解调参考信号、 专有参考信号、 随机接入响应 消息、 随机接入响应应答消息、 竟争解决消息、 系统信息和寻呼消息。
此外,第一功能集合中的功能包括的功能个数多于第二功能集合中的功能 包括的功能个数。 具体地, 如第三信号是 PUCCH, 第一功能集合和第二功能 集合包括上报信道质量信息功能,调度请求功能,是否正确接收到信号的应答 反馈功能中的一种或多种功能,但第二功能集合中包括的功能个数小于第一功 能集合中包括的功能个数。
第一处理器 302确定 UE的特征参量, UE的特征参量指的是用来度量 UE 的通信质量的值或信息, 和 /或用来度量 UE的信道质量的值或信息, 和 /或用 来反映 UE的业务特征的信息。

当确定 UE的特征参量之后, 第一处理器 302根据 UE的特征参量及预设 的对应关系确定 UE传输第一信号所用的覆盖增强技术,和 /或确定 UE支持传 输的第二信号, 和 /或确定 UE支持的第三信号的功能。
当第一处理器 302确定 UE的特征参量之后,第一处理器 302可以根据预 设的特征参量与传输第一信号所用的覆盖增强技术的对应关系确定 UE的特征 参量对应的传输第一信号所用的覆盖增强技术;
和 /或第一处理器 302根据预设的特征参量与支持传输的第二信号的对应 关系确定 UE的特征参量对应的支持传输的第二信号;
和 /或第一处理器 302根据预设的特征参量与支持的第三信号的功能的对 应关系确定 UE的特征参量对应的支持的第三信号的功能。
这里的第一信号、 第二信号、 第三信号可以相同, 也可以不同。 即, 第一 信号与第二信号可以相同, 也可以不同, 第一信号与第三信号可以相同, 也可 以不同, 第二信号和第三信号可以相同, 也可以不同。
第一信号、 或第二信号、 或第三信号包括以下至少一种:
物理下行控制信道、 增强物理下行控制信道、 物理随机接入信道、 物理控 制格式指示信道、物理混合自动重传请求指示信道、单播的物理下行共享信道、 广播或组播的物理下行共享信道、 物理上行共享信道、 物理上行控制信道、 同 步信道、 物理广播信道、 公共参考信号、 解调参考信号、 专有参考信号、 随机 接入响应消息、随机接入响应应答消息、竟争解决消息、系统信息和寻呼消息。
本实施例中的传输指的是发送或接收。
下面以 UE的特征参量为覆盖增强值为例说明 UE根据 UE的特征参量及 预设的对应关系确定 UE传输第一信号所用的覆盖增强技术,和 /或确定 UE支 持传输的第二信号, 和 /或确定 UE支持的第三信号的功能。
例如,基站或系统预先规定特征参量与传输第一信号所用的覆盖增强技术 的对应关系为: 覆盖增强值为 X dB (或大于 OdB小于等于 XdB)时, 采用第一覆 盖增强技术传输第一信号;覆盖增强值为 YdB (或大于 X dB, 或大于 XdB小于 等于 YdB)时, 采用第二覆盖增强技术传输第一信号。 这里, X和 /或 Y是预定 义的特征阀值。
若第一处理器 302确定该 UE的覆盖增强值为 X dB (或大于 OdB小于等于
XdB), 则第一处理器 302根据特征参量与传输第一信号所用的覆盖增强技术 的对应关系, 确定采用第一覆盖增强技术传输第一信号; 而若第一处理器 302 确定该 UE的覆盖增强值为 YdB (或大于 X dB,或大于 XdB小于等于 YdB),则 第一处理器 302根据特征参量与传输第一信号所用的覆盖增强技术的对应关 系, 确定采用第二覆盖增强技术传输第一信号。
在本实施例中,第一覆盖增强技术及第二覆盖增强技术可以是以下技术中 的一种, 也可以下技术中的多种的组合: 重复传输、 扩频传输、 低码率传输、 捆绑传输时间间隔 (ΤΉ bundling)传输、 功率增加 (power boosting)、 功率谱密 度增加 (PSD boosting), 不断尝试 (keep trying), 放松需求、 跳频或最大似然检 测。
更具体地, 如第一信号是物理上行控制信道 PUCCH,基站或系统预先规 定: 覆盖增强值大于 0 dB小于等于 X dB时, 采用放松需求 (和 /或跳频)来进行 PUCCH覆盖增强;覆盖增强值大于 X dB小于等于 YdB (或大于 X dB)时, 采 用放松需求 (和 /或跳频)和重复发送来进行 PUCCH覆盖增强。 这里 X和 /或 Y 是预定义的特征参量阀值。 如, 预先规定 X=5, Y=10。 若第一处理器 302确定 的覆盖增强值是 3 dB, 即覆盖增强值小于 5 dB, 因此第一处理器 302确定 PUCCH采用放松需求 (和 /或跳频)来进行 PUCCH覆盖增强。若第一处理器 302 确定的覆盖增强值是 8 dB, 即覆盖增强值大于 5 dB小于 10 dB (或大于 5 dB), 则第一处理器 302确定 PUCCH采用放松需求 (和 /或跳频)和重复发送来进行 PUCCH覆盖增强。
具体地, 再如, 第一信号是物理广播信道 PBCH,基站或系统预先规定: 覆盖增强值为 C dB时, 采用不断尝试来进行 PBCH覆盖增强; 覆盖增强值为 D dB时, 采用不断尝试和重复传输来进行 PBCH覆盖增强。这里 C和 /或 D是预 定义的特征参量阀值。 如, 预先规定 C=10, D=15。 若第一处理器 302确定覆 盖增强值是 10 dB, 则第一处理器 302确定 PBCH采用不断尝试来进行 PBCH 覆盖增强, 第一处理器 302采用不断尝试 PBCH的检测来检测 PBCH; 若第一 处理器 302确定覆盖增强值是 15 dB, 则第一处理器 302确定 PBCH采用不断 尝试和重复传输来进行 PBCH覆盖增强, 第一处理器 302采用不断尝试重复 PBCH的检测来检测 PBCH。
例如,基站或系统预先规定特征参量与支持传输的第二信号的对应关系为: 覆盖增强值为 X dB (或大于 OdB小于等于 XdB)时, UE支持传输信号集合一中 的第二信号; 覆盖增强值为 YdB (或大于 X dB,或大于 XdB小于等于 YdB)时, UE支持传输信号集合二中的第二信号。这里, X和 /或 Y是预定义的特征阀值。
若第一处理器 302确定该 UE的覆盖增强值为 X dB (或大于 OdB小于等于 XdB), 则第一处理器 302根据特征参量与支持传输的第二信号的对应关系, 确定支持传输信号集合一中的第二信号; 而若第一处理器 302确定该 UE的覆 盖增强值为 YdB (或大于 X dB,或大于 XdB小于等于 YdB),则第一处理器 302 根据特征参量与支持传输的第二信号的对应关系,确定支持传输信号集合二中 的第二信号。
更具体地,如传输信号集合一中的第二信号是 PBCH和物理混合自动重发 请求指示信道 PHICH,传输信号集合二中的第二信号是 PBCH。基站或系统预 先规定: 覆盖增强值大于 O dB小于等于 X dB时, 支持传输信号集合一中的第 二信号;覆盖增强值大于 X dB小于等于 YdB (或大于 X dB)时, 支持传输信号 集合二中的第二信号。 这里 X和 /或 γ是预定义的特征参量阀值。 如, 预先规 定 X=5, Y=10。 若第一处理器 302确定的覆盖增强值是 3 dB, 即覆盖增强值小 于 5 dB, 因此第一处理器 302确定可以支持 PBCH和 PHICH。 若第一处理器 302确定的覆盖增强值是 8 dB, 即覆盖增强值大于 5 dB小于 10 dB, 则第一处 理器 302确定支持 PBCH, 也即第一处理器 302确定不支持 PHICH。
具体地, 再如, 传输信号集合一中的第二信号是 PUCCH (或 PHICH), 传 输信号集合二中的第二信号是空信号, 即传输信号集合二中不包括任何信号。 基站或系统预先规定: 覆盖增强值大于 0 dB小于等于 X dB时, 支持传输信号 集合一中的第二信号;覆盖增强值大于 X dB小于等于 YdB (或大于 X dB)时, 支持传输信号集合二中的第二信号。这里 X和 /或 Y是预定义的特征参量阀值。 如, 预先规定 X=5, Y=10。 若 UE1的覆盖增强值是 3 dB, 则 UE1确定自己的 覆盖增强值小于 5 dB, 因此 UE1确定可以支持 PUCCH (或 PHICH)。 若 UE1 的覆盖增强值是 8 dB,则 UE1确定自己的覆盖增强值大于 5 dB小于 10 dB (或 大于 5 dB), 则 UE1确定不支持传输信号集合一中的信号, 也即 UE2确定不 支持 PUCCH (或 PHICH)。
例如,基站或系统预先规定特征参量与支持的第三信号的功能的对应关系 为: 覆盖增强值为 X dB (或大于 OdB小于等于 XdB)时, UE支持第三信号的第 一功能集合中的功能; 覆盖增强值为 YdB (或大于 X dB,或大于 XdB小于等于 YdB)时,UE支持第三信号的第二功能集合中的功能。 这里, X和 /或 Y是预定 义的特征阀值。
若第一处理器 302确定该 UE的覆盖增强值为 X dB (或大于 OdB小于等于 XdB) , 则第一处理器 302根据特征参量与支持的第三信号的功能的对应关系, 确定支持第三信号的第一功能集合中的功能; 而若第一处理器 302确定该 UE 的覆盖增强值为 YdB (或大于 X dB,或大于 XdB小于等于 YdB), 则第一处理 器 302根据特征参量与支持的第三信号的功能的对应关系,确定支持第三信号 的第二功能集合中的功能。
更具体地, 如第三信号是 PUCCH。 基站或系统预先规定: PUCCH 的第 一功能集合中的功能包括上报信道质量信息功能,调度请求功能,是否正确接 收到信号的应答反馈功能; PUCCH的第二功能集合中的功能包括调度请求功 能, 是否正确接收到信号的应答反馈功能。 并且, 基站或系统预先规定: 覆盖 增强值大于 0 dB小于等于 X dB时, 支持第三信号的第一功能集合中的功能; 覆盖增强值大于 X dB小于等于 YdB (或大于 X dB)时, 支持第三信号的第二功 能集合中的功能。 这里 X和 /或 Y是预定义的特征参量阀值。 如, 预先规定 X=5, Y=10。若第一处理器 302的覆盖增强值是 3 dB,即覆盖增强值小于 5 dB, 因此第一处理器 302确定可以支持 PUCCH的上报信道质量信息功能,调度请 求功能,是否正确接收到信号的应答反馈功能。 若第一处理器 302确定的覆盖 增强值是 8 dB, 即覆盖增强值大于 5 dB小于 10 dB (或大于 5dB),则第一处理 器 302确定支持 PUCCH的调度请求功能,是否正确接收到信号的应答反馈功 能。
需要说明的是上述对本实施例方法实施的描述是针对特征参量是覆盖增 强值时为例说明, 当特征参量是级别、 级别索引、 重复次数、 重复次数索引、 资源、 资源索引、 增强级别、 增强级别索引、 或其它 (反映通信质量、 信道质 量、 或业务特征的)信息时, 可以类似地按照上述描述进行本实施例的实施, 这里不再赘述。
本实施例中, 第一处理器可以根据自身当前的特征参量及预设的对应关 系, 自适应地确定与基站之间传输第一信号所用的覆盖增强技术, 和 /或支持 与基站之间进行传输的第二信号, 和 /或支持的第三信号的功能, 从而去适应 不同的特征参量, 以优化系统的资源利用, 降低处理复杂度, 节省功率消耗。

具体地,预设的特征参量与传输第一信号所用的覆盖增强技术的对应关系 可以为: 若特征参量小于或等于特征参量阀值, 则基站采用第一覆盖增强技术 传输第一信号, 若特征参量大于特征参量阀值, 则基站采用第二覆盖增强技术 传输第一信号, 其中, 第一覆盖增强技术和第二覆盖增强技术均是用于提高信 号传输可靠性的技术, 二者的主要区别在于: 可实现的覆盖增强强度不同; 预设的特征参量与支持传输的第二信号的对应关系可以为:若特征参量小 于或等于特征参量阀值, 则基站支持传输信号集合一中的第二信号, 若特征参 量大于特征参量阀值, 则基站支持传输信号集合二中的第二信号, 其中, 信号 集合一中的第二信号与信号集合二中的第二信号不同,这里的不同主要指的是 信号集合一包含的第二信号的类型与信号集合二包含的第二信号的类型不同, 但信号集合一包含的第二信号的数量可以与信号集合二包含的第二信号的数 量相同, 也可以不同;
预设的特征参量与支持的第三信号的功能的对应关系可以为:若特征参量 小于或等于特征参量阀值, 则基站支持使用第三信号的第一功能集合中的功 能, 若特征参量大于所述特征参量阀值, 则基站支持使用第三信号的第二功能 集合中的功能, 其中, 第一功能集合中的功能与第二功能集合中的功能不完全 相同。

本实施例中的传输指的是发送或接收。
下面以 UE的特征参量为覆盖增强值为例说明基站根据 UE的特征参量及 预设的对应关系确定基站传输第一信号所用的覆盖增强技术, 和 /或确定基站 支持传输的第二信号, 和 /或确定基站支持的第三信号的功能。
例如,基站或系统预先规定特征参量与传输第一信号所用的覆盖增强技术 的对应关系为: 覆盖增强值为 X dB (或大于 OdB小于等于 XdB)时, 采用第一覆 盖增强技术传输第一信号;覆盖增强值为 YdB (或大于 X dB, 或大于 XdB小于 等于 YdB)时, 采用第二覆盖增强技术传输第一信号。 这里, X和 /或 Y是预定 义的特征阀值。
若第二处理器 402确定一个 UE的覆盖增强值为 X dB (或大于 OdB小于等 于 XdB), 则第二处理器 402根据特征参量与传输第一信号所用的覆盖增强技 术的对应关系,确定与所述 UE进行通信时采用第一覆盖增强技术传输第一信 号; 而若第二处理器 402确定该 UE的覆盖增强值为 YdB (或大于 X dB,或大 于 XdB小于等于 YdB),则第二处理器 402根据特征参量与传输第一信号所用 的覆盖增强技术的对应关系,确定与所述 UE进行通信时采用第二覆盖增强技 术传输第一信号。
在本实施例中,第一覆盖增强技术及第二覆盖增强技术可以是以下技术中 的一种, 也可以下技术中的多种的组合: 重复传输、 扩频传输、 低码率传输、 捆绑传输时间间隔 (ΤΉ bundling)传输、 功率增加 (power boosting)、 功率谱密 度增加 (PSD boosting), 不断尝试 (keep trying), 放松需求、 跳频或最大似然检 测。
更具体地, 如第一信号是物理上行控制信道 PUCCH,基站或系统预先规 定: 覆盖增强值大于 0 dB小于等于 X dB时, 采用放松需求 (和 /或跳频)来进行 PUCCH覆盖增强;覆盖增强值大于 X dB小于等于 YdB (或大于 X dB)时, 采 用放松需求 (和 /或跳频)和重复发送来进行 PUCCH覆盖增强。 这里 X和 /或 Y 是预定义的特征参量阀值。 如, 预先规定 X=5, Y=10。 若第二处理器 402确定 UE1的覆盖增强值是 3 dB, 即覆盖增强值小于 5 dB, 因此第二处理器 402确 定 PUCCH采用放松需求 (和 /或跳频)来进行 PUCCH覆盖增强,第二处理器 402 对应地按照这种方式进行 PUCCH的接收。 若第二处理器 402确定 UE2的覆 盖增强值是 8 dB, 即覆盖增强值大于 5 dB小于 10 dB (或大于 5 dB), 则第二 处理器 402确定 PUCCH采用放松需求 (和 /或跳频)和重复发送来进行 PUCCH 覆盖增强, 第二处理器 402对应地按照这种方式进行 PUCCH的接收。
具体地, 再如, 第一信号是物理广播信道 PBCH,基站或系统预先规定: 覆盖增强值不大于 C dB时, 采用不断尝试来进行 PBCH覆盖增强;覆盖增强 值为不大于 D dB时, 采用不断尝试和重复传输来进行 PBCH覆盖增强。 这里 C和 /或 D是预定义的特征参量阀值。 如, 预先规定 C=10, D=15。 若第二处理 器 402确定当前 (一个或多个) UE的覆盖增强值不大于 10 dB, 则第二处理器 402确定 PBCH采用不断尝试来进行 PBCH覆盖增强;若第二处理器 402确定 当前 (一个或多个) UE 的覆盖增强值不大于 15 dB , 则第二处理器 402 确定 PBCH采用不断尝试和重复传输来进行 PBCH覆盖增强。
例如,基站或系统预先规定特征参量与支持传输的第二信号的对应关系为: 覆盖增强值为 X dB (或大于 OdB小于等于 XdB)时,基站支持传输信号集合一中 的第二信号; 覆盖增强值为 YdB (或大于 X dB,或大于 XdB小于等于 YdB)时, 基站支持传输信号集合二中的第二信号。 这里, X和 /或 Y是预定义的特征阀 值。
若第二处理器 402确定一个 UE的覆盖增强值为 X dB (或大于 OdB小于等 于 XdB) ,则第二处理器 402根据特征参量与支持传输的第二信号的对应关系, 确定与所述 UE进行通信时支持传输信号集合一中的第二信号; 而若第二处理 器 402确定该 UE的覆盖增强值为 YdB (或大于 X dB,或大于 XdB小于等于 YdB), 则第二处理器 402根据特征参量与支持传输的第二信号的对应关系, 确定与所述 UE进行通信时支持传输信号集合二中的第二信号。
更具体地,如传输信号集合一中的第二信号是 PBCH和物理混合自动重发 请求指示信道 PHICH,传输信号集合二中的第二信号是 PBCH。基站或系统预 先规定: 覆盖增强值大于 O dB小于等于 X dB时, 支持传输信号集合一中的第 二信号;覆盖增强值大于 X dB小于等于 YdB (或大于 X dB)时, 支持传输信号 集合二中的第二信号。 这里 X和 /或 Y是预定义的特征参量阀值。 如, 预先规 定 X=5, Y=10。 若 UE1的覆盖增强值是 3 dB , 则第二处理器 402确定 UE1的 覆盖增强值小于 5 dB , 因此第二处理器 402确定在与 UE1通信时可以支持 PBCH和 PHICH。 若第二处理器 402确定 UE2的覆盖增强值是 8 dB , 即确定 UE2的覆盖增强值大于 5 dB小于 10 dB , 则第二处理器 402确定与 UE2进行 通信时支持 PBCH, 也即与 UE2进行通信时确定不支持 PHICH。
具体地, 再如, 传输信号集合一中的第二信号是 PUCCH (或 PHICH), 传 输信号集合二中的第二信号是空信号, 即传输信号集合二中不包括任何信号。 基站或系统预先规定: 覆盖增强值大于 0 dB小于等于 X dB时, 支持传输信号 集合一中的第二信号;覆盖增强值大于 X dB小于等于 YdB (或大于 X dB)时, 支持传输信号集合二中的第二信号。这里 X和 /或 Y是预定义的特征参量阀值。 如, 预先规定 X=5, Y=10。 若第二处理器 402确定 UE1的覆盖增强值是 3 dB , 即确定 UE1的覆盖增强值小于 5 dB , 因此第二处理器 402确定与 UE1进行通 信时可以支持 PUCCH (或 PHICH)。若第二处理器 402确定 UE1的覆盖增强值 是 8 dB, 即覆盖增强值大于 5 dB小于 10 dB (或大于 5 dB),则第二处理器 402 确定与 UE1进行通信时不支持传输信号集合一中的信号, 也即基站与 UE1进 行通信时不支持 PUCCH (或 PHICH)。
例如,基站或系统预先规定特征参量与支持的第三信号的功能的对应关系 为: 覆盖增强值为 X dB (或大于 OdB小于等于 XdB)时,基站支持第三信号的第 一功能集合中的功能; 覆盖增强值为 YdB (或大于 X dB,或大于 XdB小于等于 YdB)时,基站支持第三信号的第二功能集合中的功能。 这里, X和 /或 Y是预 定义的特征阀值。
若第二处理器 402确定一个 UE的覆盖增强值为 X dB (或大于 OdB小于等 于 XdB), 则第二处理器 402根据特征参量与支持的第三信号的功能的对应关 系,确定支持第三信号的第一功能集合中的功能; 而若第二处理器 402确定所 述 UE的覆盖增强值为 YdB (或大于 X dB,或大于 XdB小于等于 YdB),则第二 处理器 402根据特征参量与支持的第三信号的功能的对应关系,确定支持第三 信号的第二功能集合中的功能。
更具体地, 如第三信号是 PUCCH。 基站或系统预先规定: PUCCH 的第 一功能集合中的功能包括上报信道质量信息功能,调度请求功能,是否正确接 收到信号的应答反馈功能; PUCCH的第二功能集合中的功能包括调度请求功 能, 是否正确接收到信号的应答反馈功能。 并且, 基站或系统预先规定: 覆盖 增强值大于 0 dB小于等于 X dB时, 支持第三信号的第一功能集合中的功能; 覆盖增强值大于 X dB小于等于 YdB (或大于 X dB)时, 支持第三信号的第二功 能集合中的功能。 这里 X和 /或 Y是预定义的特征参量阀值。 如, 预先规定 χ=5, Y=10。 若第二处理器 402确定 UE1的覆盖增强值是 3 dB, 即确定 UE1 的覆盖增强值小于 5 dB, 因此第二处理器 402确定与 UE1进行通信时可以支 持 PUCCH的上报信道质量信息功能, 调度请求功能, 是否正确接收到信号的 应答反馈功能。若第二处理器 402确定 UE1的覆盖增强值是 8 dB,即确定 UE1 的覆盖增强值大于 5 dB小于 10 dB (或大于 5dB), 则第二处理器 402确定与 UE1进行通信时支持 PUCCH的调度请求功能,是否正确接收到信号的应答反 馈功能。
需要说明的是上述对本实施例方法实施的描述是针对特征参量是覆盖增 强值时为例说明, 当特征参量是级别、 级别索引、 重复次数、 重复次数索引、 资源、 资源索引、 增强级别、 增强级别索引、 或其它 (反映通信质量、 信道质 量、 或业务特征的)信息时, 可以类似地按照上述描述进行本实施例的实施, 这里不再赘述。
本实施例中,第二处理器可以根据 UE当前的特征参量及预设的对应关系, 自适应地确定与 UE之间传输第一信号所用的覆盖增强技术, 和 /或支持与 UE 之间进行传输的第二信号, 和 /或支持的第三信号的功能, 从而去适应不同的 UE的特征参量, 以优化系统的资源利用, 降低处理复杂度, 节省功率消耗。

本实施例中,预设的对应关系可以为预设的函数关系,或预设的表格关系, 或预设的规定关系,预设的对应关系可由基站通过信令预先配置,也可以由系 统通过标准协议预先设置。

具体地,预设的特征参量与传输第一信号所用的覆盖增强技术的对应关系 可以为: 若特征参量小于或等于特征参量阀值, 则 UE采用第一覆盖增强技术 传输第一信号, 若特征参量大于特征参量阀值, 则 UE采用第二覆盖增强技术 传输第一信号, 其中, 第一覆盖增强技术和第二覆盖增强技术均是用于提高信 号传输可靠性的技术, 二者的主要区别在于: 可实现的覆盖增强强度不同; 预设的特征参量与支持传输的第二信号的对应关系可以为:若特征参量小 于或等于特征参量阀值, 则 UE支持传输信号集合一中的第二信号, 若特征参 量大于特征参量阀值, 则 UE支持传输信号集合二中的第二信号, 其中, 信号 集合一中的第二信号与信号集合二中的第二信号不同,这里的不同主要指的是 信号集合一包含的第二信号的类型与信号集合二包含的第二信号的类型不同, 但信号集合一包含的第二信号的数量可以与信号集合二包含的第二信号的数 量相同, 也可以不同;

如,信号集合二包括的信号种类小于信号集合一包括的信号种类。信号集 合一或信号集合二可以是空集合。信号集合一中的信号可以与信号集合二中的 信号完全不同, 此时若 UE支持信号集合二中的信号也表示 UE不支持信号集 合一中的信号。信号集合一或信号集合二包括以下信号中的一种或多种: 物理 下行控制信道、 增强物理下行控制信道、 物理随机接入信道、 物理控制格式指 示信道、 物理混合自动重传请求指示信道、 单播的物理下行共享信道、 广播或 组播的物理下行共享信道、物理上行共享信道、物理上行控制信道、同步信道、 物理广播信道、 公共参考信号、 解调参考信号、 专有参考信号、 随机接入响应 消息、 随机接入响应应答消息、 竟争解决消息、 系统信息和寻呼消息。

下面以 UE的特征参量为覆盖增强值为例说明 UE根据 UE的特征参量及 预设的对应关系确定 UE传输第一信号所用的覆盖增强技术,和 /或确定 UE支 持传输的第二信号, 和 /或确定 UE支持的第三信号的功能。
例如,基站或系统预先规定特征参量与传输第一信号所用的覆盖增强技术 的对应关系为: 覆盖增强值为 X dB (或大于 OdB小于等于 XdB)时, 采用第一覆 盖增强技术传输第一信号;覆盖增强值为 YdB (或大于 X dB, 或大于 XdB小于 等于 YdB)时, 采用第二覆盖增强技术传输第一信号。 这里, X和 /或 Y是预定 义的特征阀值。
若 UE确定该 UE的覆盖增强值为 X dB (或大于 OdB小于等于 XdB),则该 UE根据特征参量与传输第一信号所用的覆盖增强技术的对应关系, 确定采用 第一覆盖增强技术传输第一信号;而若 UE确定该 UE的覆盖增强值为 YdB (或 大于 X dB,或大于 XdB小于等于 YdB), 则该 UE根据特征参量与传输第一信 号所用的覆盖增强技术的对应关系, 确定采用第二覆盖增强技术传输第一信 号。
在本实施例中,第一覆盖增强技术及第二覆盖增强技术可以是以下技术中 的一种, 也可以下技术中的多种的组合: 重复传输、 扩频传输、 低码率传输、 捆绑传输时间间隔 (ΤΉ bundling)传输、 功率增加 (power boosting)、 功率谱密 度增加 (PSD boosting), 不断尝试 (keep trying), 放松需求、 跳频或最大似然检 测。
更具体地, 如第一信号是物理上行控制信道 PUCCH,基站或系统预先规 定: 覆盖增强值大于 O dB小于等于 X dB时, 采用放松需求 (和 /或跳频)来进行 PUCCH覆盖增强;覆盖增强值大于 X dB小于等于 YdB (或大于 X dB)时, 采 用放松需求 (和 /或跳频)和重复发送来进行 PUCCH覆盖增强。 这里 X和 /或 Y 是预定义的特征参量阀值。 如, 预先规定 X=5, Y=10。 若 UE1的覆盖增强值 是 3 dB, 则 UE1确定自己的覆盖增强值小于 5 dB, 因此 UE1确定 PUCCH采 用放松需求 (和 /或跳频)来进行 PUCCH覆盖增强。 若 UE2的覆盖增强值是 8 dB, 则 UE2确定自己的覆盖增强值大于 5 dB小于 10 dB (或大于 5 dB), 则 UE2确定 PUCCH采用放松需求 (和 /或跳频)和重复发送来进行 PUCCH覆盖增 强。

若 UE确定该 UE的覆盖增强值为 X dB (或大于 OdB小于等于 XdB),则该
UE根据特征参量与支持传输的第二信号的对应关系, 确定支持传输信号集合 一中的第二信号;而若 UE确定该 UE的覆盖增强值为 YdB (或大于 X dB,或大 于 XdB小于等于 YdB), 则该 UE根据特征参量与支持传输的第二信号的对应 关系, 确定支持传输信号集合二中的第二信号。
更具体地,如传输信号集合一中的第二信号是 PBCH和物理混合自动重发 请求指示信道 PHICH,传输信号集合二中的第二信号是 PBCH。基站或系统预 先规定: 覆盖增强值大于 O dB小于等于 X dB时, 支持传输信号集合一中的第 二信号;覆盖增强值大于 X dB小于等于 YdB (或大于 X dB)时, 支持传输信号 集合二中的第二信号。 这里 X和 /或 Y是预定义的特征参量阀值。 如, 预先规 定 X=5, Y=10。 若 UE1的覆盖增强值是 3 dB , 则 UE1确定自己的覆盖增强值 小于 5 dB , 因此 UE1确定可以支持 PBCH和 PHICH。 若 UE2的覆盖增强值 是 8 dB , 则 UE2确定自己的覆盖增强值大于 5 dB小于 10 dB , 则 UE2确定支 持 PBCH , 也即 UE2确定不支持 PHICH。
具体地, 再如, 传输信号集合一中的第二信号是 PUCCH (或 PHICH), 传 输信号集合二中的第二信号是空信号, 即传输信号集合二中不包括任何信号。 基站或系统预先规定: 覆盖增强值大于 0 dB小于等于 X dB时, 支持传输信号 集合一中的第二信号;覆盖增强值大于 X dB小于等于 YdB (或大于 X dB)时, 支持传输信号集合二中的第二信号。这里 X和 /或 Y是预定义的特征参量阀值。 如, 预先规定 X=5, Y=10。 若 UE1的覆盖增强值是 3 dB , 则 UE1确定自己的 覆盖增强值小于 5 dB , 因此 UE1确定可以支持 PUCCH (或 PHICH)。 若 UE1 的覆盖增强值是 8 dB ,则 UE1确定自己的覆盖增强值大于 5 dB小于 10 dB (或 大于 5 dB), 则 UE1确定不支持传输信号集合一中的信号, 也即 UE2确定不 支持 PUCCH (或 PHICH)。
例如,基站或系统预先规定特征参量与支持的第三信号的功能的对应关系 为: 覆盖增强值为 X dB (或大于 OdB小于等于 XdB)时, UE支持第三信号的第 一功能集合中的功能; 覆盖增强值为 YdB (或大于 X dB,或大于 XdB小于等于 YdB)时,UE支持第三信号的第二功能集合中的功能。 这里, X和 /或 Y是预定 义的特征阀值。
若 UE确定该 UE的覆盖增强值为 X dB (或大于 OdB小于等于 XdB),则该 UE根据特征参量与支持的第三信号的功能的对应关系, 确定支持第三信号的 第一功能集合中的功能;而若 UE确定该 UE的覆盖增强值为 YdB (或大于 X dB 或大于 XdB小于等于 YdB) , 则该 UE根据特征参量与支持的第三信号的功能 的对应关系, 确定支持第三信号的第二功能集合中的功能。
更具体地, 如第三信号是 PUCCH。 基站或系统预先规定: PUCCH的第 一功能集合中的功能包括上报信道质量信息功能,调度请求功能,是否正确接 收到信号的应答反馈功能; PUCCH的第二功能集合中的功能包括调度请求功 能, 是否正确接收到信号的应答反馈功能。 并且, 基站或系统预先规定: 覆盖 增强值大于 0 dB小于等于 X dB时, 支持第三信号的第一功能集合中的功能; 覆盖增强值大于 X dB小于等于 YdB (或大于 X dB)时, 支持第三信号的第二功 能集合中的功能。 这里 X和 /或 Y是预定义的特征参量阀值。 如, 预先规定 X=5, Y=10。 若 UE1的覆盖增强值是 3 dB , 则 UE1确定自己的覆盖增强值小 于 5 dB , 因此 UE1确定可以支持 PUCCH的上报信道质量信息功能, 调度请 求功能,是否正确接收到信号的应答反馈功能。 若 UE1的覆盖增强值是 8 dB , 则 UE1确定自己的覆盖增强值大于 5 dB小于 10 dB (或大于 5dB) , 则 UE1确 定支持 PUCCH的调度请求功能, 是否正确接收到信号的应答反馈功能。
需要说明的是上述对本实施例方法实施的描述是针对特征参量是覆盖增 强值时为例说明, 当特征参量是级别、 级别索引、 重复次数、 重复次数索引、 资源、 资源索引、 增强级别、 增强级别索引、 或其它 (反映通信质量、 信道质 量、 或业务特征的)信息时, 可以类似地按照上述描述进行本实施例的实施, 这里不再赘述。
本实施例中的传输指的是发送或接收。
本实施例中, UE可以根据自身当前的特征参量及预设的对应关系, 自适 应地确定与基站之间传输第一信号所用的覆盖增强技术, 和 /或支持与基站之 间进行传输的第二信号, 和 /或支持的第三信号的功能, 从而去适应不同的特 征参量, 以优化系统的资源利用, 降低处理复杂度, 节省功率消耗。
下面对本发明提供的信号传输方法的另一实施例进行描述, 请参阅图 6, 该方法可用于图 2或图 4所提供的基站中, 本实施例的信号传输方法包括:
601、 基站确定 UE的特征参量;
本实施例中的 UE指的是与基站进行通信的 UE, 本实施例中的 UE的特 征参量指的是用来度量 UE的通信质量的值或信息,和 /或用来度量 UE的信道 质量的值或信息, 和 /或用来反映 UE的业务特征的信息。
具体的, UE的特征参量可包括以下至少一种: 资源、 资源索引、 级别、 级别索引、 增强级别、 增强级别索引、 重复级别、 重复级别索引、 重复次数、 重复次数索引、 覆盖增强值、 覆盖增强范围的索引、 路径损耗值、 路径损耗范 围的索引、 参考信号接收功率值、 参考信号接收功率范围的索引、 参考信号接 收质量值、 参考信号接收质量范围的索引、 信道质量信息值、 信道质量信息范 围的索引、业务类型、业务类型的索引、功率节省需求、功率节省需求的索引、 时延需求、 时延需求的索引、检测预先规定的信道的次数、检测预先规定的信 道次数的索引、 移动性需求、 移动性需求的索引。
基站可以根据接收到的指示 UE的特征参量的信令确定 UE的特征参量, 这个信令可以是 UE或其他网络实体发送给基站的; 或基站根据是否能正确接 收上行信号确定 UE的特征参量, 例如, 基站向 UE发送一个下行信号, 如果 基站能够正确接收到 UE反馈的对应的上行信号, 则基站即可确定 UE的特征 参量(如表示当前通信质量的特征参量); 或基站通过对接收到的上行信号进 行测量确定 UE的特征参量; 基站自行确定 UE的特征参量。
602、 基站根据 UE的特征参量及预设的对应关系确定基站传输第一信号 所用的覆盖增强技术, 和 /或确定基站支持传输的第二信号, 和 /或确定基站支 持的第三信号的功能;
本实施例中,预设的对应关系可以为预设的函数关系,或预设的表格关系, 或预设的规定关系,预设的对应关系可由基站自身通过信令预先配置,也可以 由系统通过标准协议预先设置。
预设的对应关系指的是预设的特征参量与传输第一信号所用的覆盖增强 技术的对应关系,及预设的特征参量与支持传输的第二信号的对应关系,及预 设的特征参量与支持的第三信号的功能的对应关系。
具体地,预设的特征参量与传输第一信号所用的覆盖增强技术的对应关系 可以为: 若特征参量小于或等于特征参量阀值, 则基站采用第一覆盖增强技术 传输第一信号, 若特征参量大于特征参量阀值, 则基站采用第二覆盖增强技术 传输第一信号, 其中, 第一覆盖增强技术和第二覆盖增强技术均是用于提高信 号传输可靠性的技术, 二者的主要区别在于: 可实现的覆盖增强强度不同; 预设的特征参量与支持传输的第二信号的对应关系可以为:若特征参量小 于或等于特征参量阀值, 则基站支持传输信号集合一中的第二信号, 若特征参 量大于特征参量阀值, 则基站支持传输信号集合二中的第二信号, 其中, 信号 集合一中的第二信号与信号集合二中的第二信号不同,这里的不同主要指的是 信号集合一包含的第二信号的类型与信号集合二包含的第二信号的类型不同, 但信号集合一包含的第二信号的数量可以与信号集合二包含的第二信号的数 量相同, 也可以不同;
预设的特征参量与支持的第三信号的功能的对应关系可以为:若特征参量 小于或等于特征参量阀值, 则基站支持使用第三信号的第一功能集合中的功 能, 若特征参量大于所述特征参量阀值, 则基站支持使用第三信号的第二功能 集合中的功能, 其中, 第一功能集合中的功能与第二功能集合中的功能不完全 相同。
另外,预设的特征参量与传输第一信号所用的覆盖增强技术的对应关系也 可以为: 若特征参量属于第一特征参量集合, 则基站采用第一覆盖增强技术传 输第一信号, 若特征参量属于第二特征参量集合, 则基站采用第二覆盖增强技 术传输第一信号, 其中, 第一覆盖增强技术和第二覆盖增强技术均是用于提高 信号传输可靠性技术, 二者的主要区别在于: 可实现的覆盖增强强度不同; 预设的特征参量与支持传输的第二信号的对应关系也可以为:若特征参量 属于第一特征参量集合, 则基站支持传输信号集合一中的第二信号, 若特征参 量属于第二特征参量集合, 则基站支持传输信号集合二中的第二信号, 其中, 信号集合一中的第二信号与信号集合二中的第二信号不同,这里的不同主要指 的是信号集合一包含的第二信号的类型与信号集合二包含的第二信号的类型 不同,但信号集合一包含的第二信号的数量可以与信号集合二包含的第二信号 的数量相同, 也可以不同;
预设的特征参量与支持的第三信号的功能的对应关系也可以为:若特征参 量属于第一特征参量集合, 则基站支持第三信号的第一功能集合中的功能, 若 特征参量属于第二特征参量集合,则基站支持使用第三信号的第二功能集合中 的功能, 其中, 第一功能集合中的功能与第二功能集合中的功能不完全相同。
上述特征参量阀值、 信号集合一、 信号集合二、 第一功能集合、 第二功能 集合、 第一特征参量集合和第二特征参量集合可以由基站通过信令预先配置, 也可以由系统通过标准协议预先设置。
如,信号集合二包括的信号种类小于信号集合一包括的信号种类。信号集 合一或信号集合二可以是空集合。信号集合一中的信号可以与信号集合二中的 信号完全不同,此时若基站支持信号集合二中的信号也表示基站不支持信号集 合一中的信号。信号集合一或信号集合二包括以下信号中的一种或多种: 物理 下行控制信道、 增强物理下行控制信道、 物理随机接入信道、 物理控制格式指 示信道、 物理混合自动重传请求指示信道、 单播的物理下行共享信道、 广播或 组播的物理下行共享信道、物理上行共享信道、物理上行控制信道、同步信道、 物理广播信道、 公共参考信号、 解调参考信号、 专有参考信号、 随机接入响应 消息、 随机接入响应应答消息、 竟争解决消息、 系统信息和寻呼消息。
此外,第一功能集合中的功能包括的功能个数多于第二功能集合中的功能 包括的功能个数。 具体地, 如第三信号是 PUCCH, 第一功能集合和第二功能 集合包括上报信道质量信息功能,调度请求功能,是否正确接收到信号的应答 反馈功能中的一种或多种功能,但第二功能集合中包括的功能个数小于第一功 能集合中包括的功能个数。
当基站确定 UE的特征参量之后,可以根据预设的特征参量与传输第一信 号所用的覆盖增强技术的对应关系确定 UE的特征参量对应的传输第一信号所 用的覆盖增强技术;
和 /或基站根据预设的特征参量与支持传输的第二信号的对应关系确定 UE的特征参量对应的支持传输的第二信号;
和 /或基站根据预设的特征参量与支持的第三信号的功能的对应关系确定
UE的特征参量对应的支持的第三信号的功能。
这里的第一信号、 第二信号、 第三信号可以相同, 也可以不同。 即, 第一 信号与第二信号可以相同, 也可以不同, 第一信号与第三信号可以相同, 也可 以不同, 第二信号和第三信号可以相同, 也可以不同。
第一信号、 或第二信号、 或第三信号包括以下至少一种:
物理下行控制信道、 增强物理下行控制信道、 物理随机接入信道、 物理控 制格式指示信道、物理混合自动重传请求指示信道、单播的物理下行共享信道、 广播或组播的物理下行共享信道、 物理上行共享信道、 物理上行控制信道、 同 步信道、 物理广播信道、 公共参考信号、 解调参考信号、 专有参考信号、 随机 接入响应消息、随机接入响应应答消息、竟争解决消息、系统信息和寻呼消息。
下面以 UE的特征参量为覆盖增强值为例说明基站根据 UE的特征参量及 预设的对应关系确定基站传输第一信号所用的覆盖增强技术, 和 /或确定基站 支持传输的第二信号, 和 /或确定基站支持的第三信号的功能。
例如,基站或系统预先规定特征参量与传输第一信号所用的覆盖增强技术 的对应关系为: 覆盖增强值为 X dB (或大于 OdB小于等于 XdB)时, 采用第一覆 盖增强技术传输第一信号;覆盖增强值为 YdB (或大于 X dB, 或大于 XdB小于 等于 YdB)时, 采用第二覆盖增强技术传输第一信号。 这里, X和 /或 Y是预定 义的特征阀值。
若基站确定一个 UE的覆盖增强值为 X dB (或大于 OdB小于等于 XdB), 则基站根据特征参量与传输第一信号所用的覆盖增强技术的对应关系,确定与 所述 UE进行通信时采用第一覆盖增强技术传输第一信号; 而若基站确定该 UE的覆盖增强值为 YdB (或大于 X dB,或大于 XdB小于等于 YdB), 则该基站 根据特征参量与传输第一信号所用的覆盖增强技术的对应关系, 确定与所述 UE进行通信时采用第二覆盖增强技术传输第一信号。
在本实施例中,第一覆盖增强技术及第二覆盖增强技术可以是以下技术中 的一种, 也可以下技术中的多种的组合: 重复传输、 扩频传输、 低码率传输、 捆绑传输时间间隔 (ΤΉ bundling)传输、 功率增加 (power boosting)、 功率谱密 度增加 (PSD boosting), 不断尝试 (keep trying), 放松需求、 跳频或最大似然检 测。
更具体地, 如第一信号是物理上行控制信道 PUCCH,基站或系统预先规 定: 覆盖增强值大于 O dB小于等于 X dB时, 采用放松需求 (和 /或跳频)来进行 PUCCH覆盖增强;覆盖增强值大于 X dB小于等于 YdB (或大于 X dB)时, 采 用放松需求 (和 /或跳频)和重复发送来进行 PUCCH覆盖增强。 这里 X和 /或 Y 是预定义的特征参量阀值。 如, 预先规定 X=5, Y=10。 若基站确定 UE1的覆 盖增强值是 3 dB, 则基站确定 UE1的覆盖增强值小于 5 dB, 因此基站确定 PUCCH采用放松需求 (和 /或跳频)来进行 PUCCH覆盖增强, 基站对应地按照 这种方式进行 PUCCH的接收。 若基站确定 UE2的覆盖增强值是 8 dB, 则基 站确定 UE2确定的覆盖增强值大于 5 dB小于 10 dB (或大于 5 dB), 则基站确 定 PUCCH采用放松需求 (和 /或跳频)和重复发送来进行 PUCCH覆盖增强, 基 站对应地按照这种方式进行 PUCCH的接收。
具体地, 再如, 第一信号是物理广播信道 PBCH,基站或系统预先规定: 覆盖增强值不大于 C dB时, 采用不断尝试来进行 PBCH覆盖增强;覆盖增强 值为不大于 D dB时, 采用不断尝试和重复传输来进行 PBCH覆盖增强。 这里 C和 /或 D是预定义的特征参量阀值。 如, 预先规定 C=10, D=15。 若基站确定 当前 (一个或多个) UE的覆盖增强值不大于 10 dB,则基站确定 PBCH采用不断 尝试来进行 PBCH覆盖增强; 若基站确定当前 (一个或多个) UE的覆盖增强值 不大于 15 dB ,则基站确定 PBCH采用不断尝试和重复传输来进行 PBCH覆盖 增强。
例如,基站或系统预先规定特征参量与支持传输的第二信号的对应关系为: 覆盖增强值为 X dB (或大于 OdB小于等于 XdB)时,基站支持传输信号集合一中 的第二信号; 覆盖增强值为 YdB (或大于 X dB,或大于 XdB小于等于 YdB)时, 基站支持传输信号集合二中的第二信号。 这里, X和 /或 Y是预定义的特征阀 值。
若基站确定一个 UE的覆盖增强值为 X dB (或大于 OdB小于等于 XdB) , 则基站根据特征参量与支持传输的第二信号的对应关系,确定与所述 UE进行 通信时支持传输信号集合一中的第二信号; 而若基站确定该 UE的覆盖增强值 为 YdB (或大于 X dB,或大于 XdB小于等于 YdB) , 则基站根据特征参量与支 持传输的第二信号的对应关系,确定与所述 UE进行通信时支持传输信号集合 二中的第二信号。
更具体地,如传输信号集合一中的第二信号是 PBCH和物理混合自动重发 请求指示信道 PHICH,传输信号集合二中的第二信号是 PBCH。基站或系统预 先规定: 覆盖增强值大于 O dB小于等于 X dB时, 支持传输信号集合一中的第 二信号;覆盖增强值大于 X dB小于等于 YdB (或大于 X dB)时, 支持传输信号 集合二中的第二信号。 这里 X和 /或 Y是预定义的特征参量阀值。 如, 预先规 定 X=5, Y=10。 若 UE1的覆盖增强值是 3 dB , 则基站确定 UE1的覆盖增强值 小于 5 dB , 因此基站确定在与 UE1通信时可以支持 PBCH和 PHICH。 若基站 确定 UE2的覆盖增强值是 8 dB , 则基站确定 UE2的覆盖增强值大于 5 dB小 于 10 dB , 则基站确定与 UE2进行通信时支持 PBCH, 也即与 UE2进行通信 时确定不支持 PHICH。
具体地, 再如, 传输信号集合一中的第二信号是 PUCCH (或 PHICH), 传 输信号集合二中的第二信号是空信号, 即传输信号集合二中不包括任何信号。 基站或系统预先规定: 覆盖增强值大于 0 dB小于等于 X dB时, 支持传输信号 集合一中的第二信号;覆盖增强值大于 X dB小于等于 YdB (或大于 X dB)时, 支持传输信号集合二中的第二信号。这里 X和 /或 Y是预定义的特征参量阀值。 如, 预先规定 X=5, Y=10。 若基站确定 UE1的覆盖增强值是 3 dB , 则基站确 定 UEl的覆盖增强值小于 5 dB, 因此基站确定与 UE1进行通信时可以支持 PUCCH (或 PHICH)。 若基站确定 UEl的覆盖增强值是 8 dB, 则基站确定 UEl 的覆盖增强值大于 5 dB小于 10 dB (或大于 5 dB), 则基站确定与 UE1进行通 信时不支持传输信号集合一中的信号, 也即基站与 UE1 进行通信时不支持 PUCCH (或 PHICH)。
例如,基站或系统预先规定特征参量与支持的第三信号的功能的对应关系 为: 覆盖增强值为 X dB (或大于 OdB小于等于 XdB)时,基站支持第三信号的第 一功能集合中的功能; 覆盖增强值为 YdB (或大于 X dB,或大于 XdB小于等于 YdB)时,基站支持第三信号的第二功能集合中的功能。 这里, X和 /或 Y是预 定义的特征阀值。
若基站确定一个 UE的覆盖增强值为 X dB (或大于 OdB小于等于 XdB), 则基站根据特征参量与支持的第三信号的功能的对应关系,确定支持第三信号 的第一功能集合中的功能; 而若基站确定所述 UE的覆盖增强值为 YdB (或大 于 X dB,或大于 XdB小于等于 YdB), 则基站根据特征参量与支持的第三信号 的功能的对应关系, 确定支持第三信号的第二功能集合中的功能。
更具体地, 如第三信号是 PUCCH。 基站或系统预先规定: PUCCH的第 一功能集合中的功能包括上报信道质量信息功能,调度请求功能,是否正确接 收到信号的应答反馈功能; PUCCH的第二功能集合中的功能包括调度请求功 能, 是否正确接收到信号的应答反馈功能。 并且, 基站或系统预先规定: 覆盖 增强值大于 0 dB小于等于 X dB时, 支持第三信号的第一功能集合中的功能; 覆盖增强值大于 X dB小于等于 YdB (或大于 X dB)时, 支持第三信号的第二功 能集合中的功能。 这里 X和 /或 Y是预定义的特征参量阀值。 如, 预先规定 χ=5, Y=10。 若基站确定 UEl的覆盖增强值是 3 dB, 则基站确定 UEl的覆盖 增强值小于 5 dB, 因此基站确定与 UE1进行通信时可以支持 PUCCH的上报 信道质量信息功能, 调度请求功能, 是否正确接收到信号的应答反馈功能。 若 基站确定 UE1的覆盖增强值是 8 dB,则基站确定 UEl的覆盖增强值大于 5 dB 小于 10 dB (或大于 5dB), 则基站确定与 UE1进行通信时支持 PUCCH的调度 请求功能, 是否正确接收到信号的应答反馈功能。
需要说明的是上述对本实施例方法实施的描述是针对特征参量是覆盖增 强值时为例说明, 当特征参量是级别、 级别索引、 重复次数、 重复次数索引、 资源、 资源索引、 增强级别、 增强级别索引、 或其它 (反映通信质量、 信道质 量、 或业务特征的)信息时, 可以类似地按照上述描述进行本实施例的实施, 这里不再赘述。
本实施例中的传输指的是发送或接收。
本实施例中, 基站可以根据 UE当前的特征参量及预设的对应关系, 自适 应地确定与 UE之间传输第一信号所用的覆盖增强技术,和 /或支持与 UE之间 传输的第二信号,和 /或支持的第三信号的功能,从而去适应不同 UE的特征参 量, 以优化系统的资源利用, 降低处理复杂度, 节省功率消耗。
