25.2013GPPPhysical layer - general descriptionRelease 17TS
5.1 Overview
The physical layer specification consists of a general document (TS 25.201), five FDD mode documents (TS 25.211 through 25.215), five TDD mode documents (TS 25.221 through 25.225). In addition, there are two technical reports (TR 25.833 and 25.944).

Annex A (informative):
Preferred mathematical notations
The following table contains the preferred mathematical notations used in L1 documentation.
Item |
Notation |
---|---|
multiply product |
cross sign, e.g. ab |
matrix product |
dot sign, e.g. ab |
scalar product (product of a matrix by a scalar) |
dot sign, scalar should precede matrix e.g. |
matrix dimensioning |
number of rows number of column, e.g.: RC |
Kronecker product |
ab |
bracketing of sets (all elements of same type, not ordered elements) |
curly brackets {}, e.g. {a1, a2, …,ap}, or |
bracketing of lists (all elements not necessary of same type, ordered elements) |
round brackets (), e.g. (A, u, x) |
bracketing of sequences (all elements of same type, ordered elements) |
angle brackets, e.g. <a1, a2, …,ap> or |
bracketing of function argument |
round brackets, e.g. f(x) |
bracketing of array index |
square brackets, e.g. a[x] |
bracketing of matrix or vector |
square brackets [], e.g. , , or |
Separation of indexes |
use a comma : e.g. Ni,j |
use of italic for symbols |
a symbol should be either in italic or in normal font, but mixing up should be avoided. |
bracketing of arithmetic expression to force precedence of operations |
round brackets : e.g. |
necessity of bracketing arithmetic expressions |
When only + and bracketing is not necessary. When the mod operator is used explicit bracketing of mod operands and possibly result should be done. |
number type |
in a context of non negative integer numbers, some notes should stress when a number is signed, or possibly fractional. |
binary xor and and |
respectively use + or . If no "mod 2" is explicitly in the expression some text should stress that the operation is modulo 2. |
matrix or vector transpose |
vT |
11 matrices |
implicitly cast to its unique element. |
vector dot product |
uTv for column vectors, and uvT for line vectors |
complex conjugate |
v* |
matrix or vector Hermitian transpose |
vH |
real part and imaginary part of complex numbers. |
Re(x) and Im(x) |
