`Resource blocks
`Resource blocks are used to describe the mapping of certain physical channels to resource elements. Physical and
`virtual resource blocks are defined.
`A physical resource block is defined as NYmb consecutive OFDM symbols in the time domain and N
`
`consecutive
`
`subcarriers in the frequency domain, where Ny'DL and N'r are given by Table 6.2.3-1. A physical resource block thus
`consists of NybI x N? resource elements, corresponding to one slot in the time domain and 180 kHz in the frequency
`domain.
`
`Physical resource blocks are numbered from 0 to NI,& -1 in the frequency domain. The relation between the physical
`resource block number npm in the frequency domain and resource elements (k, 1) in a slot is given by

`A virtual resource block is of the same size as a physical resource block. Two types of virtual resource blocks are
`defined:
`
`Virtual resource blocks of localized type
`
`- Virtual resource blocks of distributed type
`
`For each type of virtual resource blocks, a pair of virtual resource blocks over two slots in a subframe is assigned
`together by a single virtual resource block number, nWBR.
`
`6.2.3.1
`
`Virtual resource blocks of localized type
`
`Virtual resource blocks of localized type are mapped directly to physical resource blocks such that virtual resource

`Resource-element groups
`Resource-element groups are used for defining the mapping of control channels to resource elements.
`
`A resource-element group is represented by the index pair (k',I') of the resource element with the lowest index k in
`the group with all resource elements in the group having the same value of 1. The set of resource elements (k, I) in a
`resource-element group depends on the number of cell-specific reference signals configured as described below with
`o -ppB" N? , 0 < npti < N".
`
`In the first OFDM symbol of the first slot in a subframe the two resource-element groups in physical resource
`block npmR consist of resource elements (k, I = 0) with k = ko + 0, ko + 1..., ko + 5 and
`k = k0 + 6, ko + 7,..., ko + 11, respectively.
`
`In the second OFDM symbol of the first slot in a subframe in case of one or two cell-specific reference signals
`configured, the three resource-element groups in physical resource block nprB consist of resource elements
`(k,l=l) with k=kO + O,ko +1,,.., k0 +3, k=k o +4,k+5,...,k0 +7 and k=k o +8,k o +9...,k,+ll,

`
`Mapping of a symbol-quadruplet (z(i), z(i + I), z(i + 2), z(i + 3)) onto a resource-element group represented by resource-
`element (k',l') is defined such that elements z(i) are mapped to resource elements (k,I) of the resource-element
`group not used for cell-specific reference signals in increasing order of i and k. In case a single cell-specific reference
`signal is configured, cell-specific reference signals shall be assumed to be present on antenna ports 0 and 1 for the
`purpose of mapping a symbol-quadruplet to a resource-clement group, otherwise the number of cell-specific reference
`signals shall be assumed equal to the actual number of antenna ports used for cell-specific reference signals. The UE
`shall not make any assumptions about resource elements assumed to be reserved for reference signals but not used for
`transmission of a reference signal.

`
`General structure for downlink physical channels
`This section describes a general structure, applicable to more than one physical channel.
`
`The baseband signal representing a downlink physical channel is defined in terms of the following steps:

`-
`
`scrambling of coded bits in each of the code words to be transmitted on a physical channel
`
`- modulation of scrambled bits to generate complex-valued modulation symbols
`
`- mapping of the complex-valued modulation symbols onto one or several transmission layers

`-
`
`precoding of the complex-valued modulation symbols on each layer for transmission on the antenna ports
