步骤 504, 用户设备根据 MAC sub-header携带的激活信息, 对网络侧配置 的载波进行激活或去激活。
对多载波激活 /去激活相关的 MAC CE各字段的设计, 包括以下两种方案: ( 1 )用 MAC sub-header表示 UE所有可用载波的激活 /去激活过程。
其中, sub-header 中的 LCID 采用目前预留的比特方式中的一种, 例如 01011, 来表示 UE所有可用栽波的激活 /去激活过程, 不需要设计专门的 MAC Cli字段内容, 即 sub-header对应的 MAC CE填充比特为零。 LCID可以不指示 激活信息的类型。 UE接收到该 LCID后,可以根据该 LCID指示的载波的当前 状态, 对该栽波进行激活或去激活。 具体地, 如果 UE的所有可用载波的当前 状态为激活状态, 则 UE对所有可用栽波进行去激活; 如果 UE的所有可用载 波的当前状态为去激活状态, 则 UE对所有可用载波进行激活。
此外, 当 LCID表示 UE所有可用栽波的激活 /去激活过程时, 还可以用 sub-header中的 R比特表示该信令是激活还是去激活信令。 编码方案可以为: R比特设置为 1时, 表示该信令为栽波激活信令; R比特设置为 0时, 表示该 信令为栽波去激活信令。 当然, 也可以采用与上述编码方案相反的设置。
另外, 当 LCID表示 UE所有可用载波的激活 /去激活过程时, 还可以直接 用 LCID区分信令为激活信令还是去激活信令, 例如, 01011表示载波激活, 01101表示栽波去激活信令。
( 2 )用 MAC sub-header字段表示 UE需要激活 /去激活载波的标识。
其中, sub-header 中的 LCID 采用目前预留的比特方式的中一种, 例如 01011 , 来表示 UE在该 sub-header对应的 MAC CE中需要激活 /去激活栽波的 载波标识。 LCID可以不指示激活信息的类型。 UE接收到该 LCID后, 可以根 据该 LCID指示的载波的当前状态, 对该载波进行激活或去激活。 具体地, 如 果 IJE的该 LCID指示的载波的当前状态为激活状态, 则 UE对该载波进行去 激活; 如果 UE的该 LCID指示的栽波的当前状态为去激活状态, 则 UE对该 载波进行激活。
此外, 当 LCID 表示 UE 需要激活 /去激活栽波的标识时, 还可以用 sub-header中的 R比特表示该信令是激活还是去激活信令; 编码方案为: R比 特设置为 1, 表示该信令是栽波激活; R比特设置为 0, 表示该信令为载波去 激活信令, 当然, 也可以采用与上述编码方案相反的设置。
另外, 还可以通过 MAC CE携带激活 /去激活的栽波标识, 或者其他可以 表示对应的激活 /去激活栽波的信息。并使用 LCID区分信令为激活信令还是去 激活信令。 具体地, 上述 LCID可以采用一种预留的比特方式表示激活信息的 类型为激活信令和去激活信令, UE接收到该 LCID后, 可以根据对应的 MAC CE指示的载波的当前状态, 对该栽波进行激活或去激活。 如果 UE的该 MAC CE指示的载波的当前状态为激活状态, 则 UE对该栽波进行去激活; 如果 UE 的该 MAC CE指示的载波的当前状态为去激活状态,则 UE对该栽波进行激活。
上述 LCID还可以采用两种预留的比特方式表示激活信息的类型, 一种预 留的比特方式用于表示激活信息的类型为激活信令, 另一种预留的比特方式用 于表示激活信息的类型为去激活信令。 例如 01011表示激活信息的类型为激活 信令, 01101表示激活信息的类型为去激活信令。
本发明实施例利用 MAC CE以及对应的 sub-header进行载波激活 /去激活 信令的设计, 使得 UE能够在保证该信令接收有效性的前提下减少 UE解码时 延, 提高系统性能, 节省 UE的电量; 同时, 使用 LCID或者预留比特区分激 活还是去激活信令, 能够减少比特开销。 地, 本发明实施例还提供了应用上述栽波激活方法的装置和系统。
