标准协议之3GPP标准协议
所有3G和GSM规范具有一个由4或5位数字组成的3GPP编号。（例如：09.02或29.002）。前两位数字对应下表所列的系列。接着的两位数字对应01-13系列，或3位数字对应21-55系列。词"3G"意味着采用UTRAN无线接入网的3GPP系统，词"GSM" 意味着采
用GERAN无线接入网的3GPP系统（因而，"GSM"包
括GPRS和EDGE性能）。
21-35系列规范只用于3G或既用于GSM也用于3G。第三位数字为"0"表示用于两个系统，例如29.002用于3G和GSM系统，
而25.101和25.201仅用于3G。其它系列的大多数规范仅用
于GSM系统。然而当规范编号用完后，须查看每个规范的信息页面（见下表）或查看01.01 / 41.101 (GSM) 和21.101 (3G) 中的目录。
The 3GPP Specifications are stored on the file server as zipped MS-Word files. The filenames have the following structure:
SM[-P[-Q]]-V.zip
where the character fields have the following significance ...
S = series number - 2 characters (see the table above)
M = mantissa (the part of the spec number after the series number) - 2 or 3 characters (see above)
P = optional part number - 1 or 2 digits if present
Q = optional sub-part number - 1 or 2 digits if present
V = version number, without separating dots - 3 digits
So for example:
21900-320.zip is 3GPP TR 21.900 version 3.2.0
0408-6g0.zip is 3GPP TS 04.08 version 6.16.0
32111-4-410 is 3GPP TS 32.111 part 4 version 4.1.0
29998-04-1-100 is 3GPP TS 29.998 part 4 sub-part 1 version 1.0.0
3GPP规范采用WORD文件的ZIP压缩格式保存，文件名结构如下：
SM[-P[-Q]]-V.zip
S=系列号-两位数字（见上表）
M=尾数（规范编号中系列号后面的部分）-2或3位数字
P=可选的部分编号-1或2位数字，如果有
Q=可选的子部分编号-1或2位数字，如果有
V=版本号，无分隔点-3位数字
例如：
21900-320.zip 是3GPP TR 21.900 版本3.2.0
0408-6g0.zip 是3GPP TS 04.08 版本6.16.0
32111-4-410 是3GPP TS 32.111 部分4 版本4.1.0
29998-04-1-100 是3GPP TS 29.998 部分4 子部分1 版本

好好研究下这个网站
/specification-numbering
就明白了每一个小类后面都有说明的

mark。协议里给的是结果，最近看协议想了解其原理，可惜不知道如何查找提案。比如不知道PUCCH设计的原理，想查一下相关的提案却不知道如何查，有明白的xd给指点一下。另外，/ftp/tsg_ran/WG1_RL1/下面是不是放的就是提案？
