上行参考信号的生成与映射..docx

参考信号序列产生参考信号序列定义为基序列的循环移位，按照下式进行，即有：其中参考信号序列长度，且。多个参考信号序列可由一个基序列和不同的循环移位值得到。基序列被分为多组，其中表示组号，表示组内基序列号，使得每组在时包含一个长度为的基序列（）；在时包含两个长度为的基序列（）。序列组号和组内序号随时间而变化详见1.3 和 1.4节。基序列的定义取决于序列长度。长度为或更长的基序列对，基序列由下式得到：其中，第个根ZC序列定义为：其中由下式得到：ZC序列的长度取值为满足的最大素数。长度小于的基序列当和时，基序列由下式给出：其中值见表5.5.1.2-1和表5.5.1.2-2，分别对应于和。表5.5.1.2-1：时的定义0-113-333113111-3-31-33211-3-3-3-1-3-31-31-13-11111-1-3-31-33-14-131-11-1-3-11-11351-33-1-111-1-13-316-13-3-3-331-133-317-3-1-1-11-33-11-33181-331-1-1-1113-1191-3-133-113-111-3-3-1-3-33-11131-1-133-313133121-311-3111-3-3-311333-33-3113-1-33314-31-1-3-131333-11153-11-3-1-11131-1-316131-11333-1-13-117-3113-33-3-3313-118-3311-31-3-3-1-11-319-13131-1-13-3-1-3-120-1-3111131-11-3-121-13-11-3-3-3-3-31-1-32211-3-3-3-3-13-31-332311-1-3-1-31-113-1124113133-11-1-3-31251-3331331-3-1-132613-3-33-31-1-13-1-327-3-1-3-1-331-113-3-328-13-33-133-333-1-1293-3-3-1-1-3-13-331-1表 5.5.1.2-2: 时的定义0-131-33-113-3313-3311-113-33-3-1-31-33-3-3-31-3-33-111131-13-3-31311-323-13311-333331-13-111-1-3-1-11333-1-3113-311-3-1-113131-1311-3-1-3-14-1-1-1-3-3-11133-13-11-1-31-1-3-31-3-1-15-3113-1131-31-311-1-13-1-33-3-3-311611-1-13-3-33-31-1-11-111-1-3-11-13-1-37-333-1-1-3131-113-3-1-118-313-31-1-33-33-1-1-1-11-3-3-31-3-3-31-3911-333-1-3-13-3333-111-31-111-31110-11-3-33-13-1-1-3-3-3-1-3-31-1133-11-1311133-3-3131-1-3-3-333-333-1-33-11-3112133111-1-11-33-111-333-1-33-3-1-3-1133-1-1-1-1-3-1331-11333-111-313-1-3314-3-331311-1-31-3-1311315-1-11-313-31-1-3-13131-1-3-3-1-1-3-3-3-116-1-33-1-1-1-111-331331-11-31-311-3-11713-133-1-31-1-3333-1113-1-3-13-1-113-1-3113-31-3-111-3-3311-3191331-1-33-1333-31-11-1-3-113-13-3-320-1-33-3-3-3-1-1-3-1-3313-3-13-11-13-31-121-3-311-11-11-131-3-11-11-1-133-3-11-322-3-1-331-1-3-1-3-33-33-3-1131-3133-1-323-1-1-1-1333133-313-13-133-331-133241-133-1-33-3-1-13-13-1-11111-1-1-3-13251-11-13-1311-1-1-311-313-311-3-3-1-126-3-11311-3-1-1-33-331-33-31-11-311127-1-333113-1-3-1-1-131-3-3-13-3-1-3-1-3-128-1-3-1-11-3-1-11-1-311-31-3-3311-13
