图 1为本申请一实施例提供的上行控制信息处理方法的流程示意图, 如图 1所示。
101、 终端接收基站发送的指示信息, 所述指示信息用于指示根据第 一功率偏置发送上行控制信息。
102、 所述终端根据所述指示信息, 通过 E-DPCCH向所述基站发送 第一上行控制信息。
可选地, 在本实施例的一个可能的实现方式中, 所述指示信息可以 为一个显式的指示。
例如, 显式的指示可以为第一功率偏置切换指示, 用于指示根据所 述第一功率偏置发送上行控制信息。
具体地, 如果所述指示信息为第一功率偏置切换指示, 则在 101 中, 所述终端具体可以通过高速共享控制信道 ( High Speed Shared Control CHannel , 简称 HS-SCCH )或其他方式,接收所述基站发送的指示信息。 也就是说, 当所述基站确定所述终端开始发送上行数据时, 在所述终端 的緩存的数据发送完毕之前, 所述基站则可以预期所述终端在后续会一 直发送上行数据, 因此, 所述基站不再需要检测接收到的信息的发送功 率是否大于预先设置的功率阈值。 所述基站则可以通过 HS-SCCH 或其 他方式, 向所述终端发送所述指示信息。 具体地, 所述基站可以根据调 度信息 (Schedule Information , SI ) , 确定所述终端发送的上行数据的 大小。
可选地, 在本实施例的一个可能的实现方式中, 所述指示信息还可 以为一个隐式的指示。
例如, 隐式的指示可以为上行数据的绝对授权命令, 如携带绝对授 权值的绝对授权命令、 进程激活指令或进程去激活指令。
具体地, 如果所述指示信息为上行数据的绝对授权命令, 则在 101 中, 所述终端具体可以通过 E-DCH 绝对授权信道 ( E-DCH Absolute Grant CHannel , E-AGCH )或其他方式,接收所述基站发送的指示信息。 也就是说, 当所述基站确定所述终端开始发送上行数据时, 所述基站则 可以向所述终端发送上行数据的绝对授权命令, 这就说明, 在所述终端
的緩存的数据发送完毕之前, 所述基站则可以预期所述终端在后续会一 直发送上行数据, 因此, 所述基站不再需要检测接收到的信息的发送功 率是否大于预先设置的功率阈值。 因为基站发送绝对授权命令是基于收 到的终端的发送的调度信息 ( Schedule Information , SI ) 或者上行数据 而发送的, 所以, 终端收到绝对授权命令时可以认为基站已经检测到终 端的上行发送, 所述终端则可以将所述上行数据的绝对授权命令作为所 述指示信息。 根据该指示信息确定使用较低的第一功率偏置发送上行控 制信息。 进一步地, 终端还可以根据收到的绝对授权命令调整之后的服 务授权值进行判断是否使用第一功率偏置发送上行控制信息。 例如, 如 果调整之后的服务授权值大于或等于预先设置的阈值, 所述终端则可以 将所述绝对授权值作为所述指示信息, 使用较低的第一功率偏置发送上 行控制信息。 因为在绝对授权值较高的情况下, 所述终端发送的上行数 据的大小比较大, 如果使用较高的控制信道的功率偏置会导致数据信道 的可用功率降低, 反之亦然, 因此根据绝对授权值来判断使用的功率偏 置大小可以更合理利用上行的功率。
或者再例如, 隐式的指示可以为上行数据的相对授权命令, 如相对 授权调整命令。
具体地, 如果所述指示信息为上行数据的相对授权命令, 则在 101 中,所述终端具体可以通过 E-DCH相对授权信道( E-DCH Relative Grant CHannel , E-RGCH )或其他方式, 接收所述基站发送的指示信息。 也就 是说, 当所述基站确定所述终端开始发送上行数据时, 所述基站则可以 向所述终端发送上行数据的相对授权命令, 这就说明, 在所述终端的緩 存的数据发送完毕之前, 所述基站则可以预期所述终端在后续会一直发 送上行数据, 因此, 所述基站不再需要检测接收到的信息的发送功率是 否大于预先设置的功率阈值。 因为基站发送相对授权命令是基于收到的 终端的发送的调度信息 ( Schedule Information , SI ) 或者上行数据而发 送的, 所以, 终端收到相对授权命令时可以认为基站已经检测到终端的 上行发送, 所述终端则可以将所述上行数据的相对授权命令作为所述指 示信息。 根据该指示信息确定使用较低的第一功率偏置发送上行控制信 息。 进一步地, 终端还可以根据收到的相对授权命令调整之后的服务授
权值进行判断是否使用第一功率偏置发送上行控制信息。 例如, 如果调 整之后的服务授权值大于或等于预先设置的阈值, 所述终端则可以将所 述绝对授权值作为所述指示信息, 使用较低的第一功率偏置发送上行控 制信息。 因为在调整之后的服务授权值较高的情况下, 所述终端发送的 上行数据的大小比较大, 如果使用较高的控制信道的功率偏置会导致数 据信道的可用功率降低, 反之亦然, 因此根据调整之后的服务授权值来 判断使用的功率偏置大小可以更合理利用上行的功率。
或者再例如, 隐式的指示可以为上行数据正确接收的确认信息, 如 肯定确认( ACKnowledgment, 简称 ACK ) 。
具体地, 如果所述指示信息为上行数据的相对授权命令, 则在 101 中, 所述终端具体可以通过 E-DCH混合自动重传请求指示信道 ( E-DCH Hybrid Automatic Repeat Request Indicator CHannel , E-HICH )或其他 方式, 接收所述基站发送的指示信息。
可选地, 在本实施例的一个可能的实现方式中, 在 101 之前, 所述 终端还可以进一步根据第二功率偏置, 通过所述 E-DPCCH 向所述基站 发送第二上行控制信息。
其中, 所述第一功率偏置小于第二功率偏置。
具体地, 所述基站可以通过检测接收到的信息的发送功率是否大于 预先设置的功率阈值, 以确认该信息是否为上行控制信息。 因此, 终端 必须利用根据第二功率偏置确定的大于或等于所述功率阈值的发送功 率, 发送上行控制信息, 才能够被基站正确接收。 当基站检测到上行控 制信息时, 所述基站则可以确定所述终端即将发送上行数据或者已经开 始发送上行数据。 因此, 所述基站不再需要检测接收到的信息的发送功 率是否大于预先设置的功率阈值, 也能够准备解码所述终端发送的上行 数据, 那么所述终端则也可以不再利用大于或等于所述功率阈值的发送 功率, 发送上行控制信息, 即所述终端则可以利用根据第一功率偏置确 定的小于所述功率阈值的发送功率, 发送上行控制信息。 所以, 所述第 一功率偏置可以小于第二功率偏置。
由于所述第一功率偏置较小, 因此, 能够避免现有技术中由于多个 终端同时以预先指定的大于或等于所述功率阈值的发送功率向基站发送
上行控制信息而导致的相互干扰的问题, 从而提高了系统的容量。
可选地, 在本实施例的一个可能的实现方式中, 在 102之后, 所述 终端还可以进一步根据第二功率偏置, 通过所述 E-DPCCH 向所述基站 发送第二上行控制信息。
其中, 所述第一功率偏置小于第二功率偏置。
例如, 在所述终端根据第二功率偏置, 通过所述 E-DPCCH 向所述 基站发送第二上行控制信息之前, 所述终端还可以进一步确定所述终端 的緩存中没有待发送的上行数据。 由于所述终端发送完毕上行数据之后, 不会再发送控制信息, 因此, 所述基站仍然需要通过检测接收到的信息 的发送功率是否大于预先设置的功率阈值, 以确认该信息是否为上行控 制信息。 此时, 终端必须利用根据第二功率偏置确定的大于或等于所述 功率阈值的发送功率, 发送上行控制信息, 才能够被基站正确接收。 进 一步地, 在所述终端确定所述终端的緩存中没有待发送的上行数据之后, 所述终端还可以进一步向所述基站发送用于指示所述终端的緩存为空的 调度信息( Schedule Information , SI )。 所述基站接收该调度信息之后, 则可以根据所述调度信息, 确定所述终端的緩存中没有待发送的上行数 据, 从而使得所述基站通过所述 E-DPCCH , 接收所述终端根据第二功率 偏置发送的第二上行控制信息。
或者再例如, 在所述终端根据第二功率偏置, 通过所述 E-DPCCH 向所述基站发送第二上行控制信息之前, 所述终端也可以进一步确定在 预先设置的时间范围内, 没有接收到所述基站发送的上行数据正确接收 的确认信息。 由于所述基站没有发送上行数据正确接收的确认信息, 可 能是因为上行控制信息的解析出错, 此时, 所述终端根据第二功率偏置, 通过所述 E-DPCCH 向所述基站发送第二上行控制信息, 能够有助于基 站正确解析上行控制信息。
或者再例如, 在所述终端根据第二功率偏置, 通过所述 E-DPCCH 向所述基站发送第二上行控制信息之前, 所述终端也可以进一步接收所 述基站发送的第二功率偏置切换指示, 用于指示根据所述第二功率偏置 发送上行控制信息。 如果基站确定所述终端的緩存中没有待发送的上行 数据, 或者确定所述第一功率偏置过低, 则可以向所述终端发送所述第
二功率偏置切换指示。
可选地, 在本实施例的一个可能的实现方式中, 在 102之前, 所述 终端还可以进一步获得所述第一功率偏置。 例如, 所述终端可以接收基 站控制设备发送的所述第一功率偏置; 或者还可以接收基站控制设备发 送的第二功率偏置和功率偏置偏移量, 根据所述第二功率偏置和所述功 率偏置偏移量, 确定所述第一功率偏置。
可以理解的是, 本实施例中所涉及的所述第二功率偏置可以认为是 现有技术中的功率偏置, 根据该功率偏置确定的发送功率应该是大于基 站检测上行控制信息的功率阈值的。 所述第二功率偏置的详细描述可以 参见现有技术中的相关内容, 此处不再赘述。
本实施例中, 通过终端接收基站发送的指示信息, 所述指示信息用 于指示根据第一功率偏置发送上行控制信息, 使得所述终端能够根据所 述指示信息, 通过 E-DPCCH 向所述基站发送第一上行控制信息, 由于 所述终端根据所述基站发送的指示信息所指示的第一功率偏置确定发送 功率以发送上行控制信息, 因此, 能够有效提高上行控制信息的发送灵 活性。 图 2 为本申请另一实施例提供的上行控制信息处理方法的流程示意 图, 如图 2所示。

203、 所述基站通过 E-DPCCH , 接收所述终端根据所述指示信息, 发送的第一上行控制信息。
可选地, 在本实施例的一个可能的实现方式中, 所述指示信息可以 为一个显式的指示。
例如, 显式的指示可以为第一功率偏置切换指示, 用于指示根据所 述第一功率偏置发送上行控制信息。
具体地, 如果所述指示信息为第一功率偏置切换指示, 则在 202中, 所述基站具体可以通过高速共享控制信道 ( High Speed Shared Control
CHannel , 简称 HS-SCCH )或其他方式, 向所述终端发送所述指示信息。 也就是说, 当所述基站确定所述终端开始发送上行数据时, 在所述终端 的緩存的数据发送完毕之前, 所述基站则可以预期所述终端在后续会一 直发送上行数据, 因此, 所述基站不再需要检测接收到的信息的发送功 率是否大于预先设置的功率阈值。 所述基站则可以通过 HS-SCCH 或其 他方式, 向所述终端发送所述指示信息。 具体地, 所述基站可以根据调 度信息 (Schedule Information , SI ) , 确定所述终端发送的上行数据的 大小。

的可用功率降低, 反之亦然, 因此根据绝对授权值来判断使用的功率偏 置大小可以更合理利用上行的功率。
或者再例如, 隐式的指示可以为上行数据的相对授权命令, 如相对 授权调整命令。
具体地, 如果所述指示信息为上行数据的相对授权命令, 则在 202 中,所述基站具体可以通过 E-DCH相对授权信道( E-DCH Relative Grant CHannel , E-RGCH )或其他方式, 向所述终端发送所述指示信息。 也就 是说, 当所述基站确定所述终端开始发送上行数据时, 所述基站则可以 向所述终端发送上行数据的相对授权命令, 这就说明, 在所述终端的緩 存的数据发送完毕之前, 所述基站则可以预期所述终端在后续会一直发 送上行数据, 因此, 所述基站不再需要检测接收到的信息的发送功率是 否大于预先设置的功率阈值。 因为基站发送相对授权命令是基于收到的 终端的发送的调度信息 ( Schedule Information , SI ) 或者上行数据而发 送的, 所以, 终端收到相对授权命令时可以认为基站已经检测到终端的 上行发送, 所述终端则可以将所述上行数据的相对授权命令作为所述指 示信息。 根据该指示信息确定使用较低的第一功率偏置发送上行控制信 息。 进一步地, 终端还可以根据收到的相对授权命令调整之后的服务授 权值进行判断是否使用第一功率偏置发送上行控制信息。 例如, 如果调 整之后的服务授权值大于或等于预先设置的阈值, 所述终端则可以将所 述绝对授权值作为所述指示信息, 使用较低的第一功率偏置发送上行控 制信息。 因为在调整之后的服务授权值较高的情况下, 所述终端发送的 上行数据的大小比较大, 如果使用较高的控制信道的功率偏置会导致数 据信道的可用功率降低, 反之亦然, 因此根据调整之后的服务授权值来 判断使用的功率偏置大小可以更合理利用上行的功率。
