6.1.1 物理信道
A downlink physical channel corresponds to a set of resource elements carrying information originating from higher layers and is the interface defined between 36.212 and 36.211. The following downlink physical channels are defined:
3GPP
Release 8 38 3GPP TS 36.211 V8.5.0 (2008-12)
- 物理下行共享信道, PDSCH - 物理广播信道, PBCH - 物理多播信道, PMCH
- 物理控制格式指示信道, PCFICH - 物理下行控制信道, PDCCH - 物理混合ARQ 指示信道, PHICH

时隙结构和物理资源单元
资源格
DLRBDLDL每时隙中资源格定义为NRBOFDM符号。 NRB取决于高层配置的下行带宽,满足 Nsc个子载波和Nsymbmin,DLDLmax,DL6?NRB?NRB?NRB?110
DL参见表6.2.3-1。 Nsymb多天线传输情况下,每个天线端口定义一个资源格。天线端口由相应的参考信号定义。所支持的天线端口集取决于小区内参考信号配置。
- 小区专用参考信号CRS,用于非MBSFN传输, 支持1个、2个或4个天线端口的配置,这里天线端口号
p 应分别满足p?0, p??0,1?和p??0,1,2,3?。 - MBSFN 参考信号, 用于MBSFN 传输, 在天线端口p?4上传输。 - UE专用参考信号DRS,在天线端口p?5上传输。

6.2.3.2 分布类型虚拟资源块
Virtual resource blocks of distributed type are mapped to physical resource blocks as described below.

DLThe parameter Ngap is given by Table 6.2.3.2-1. For 6?NRB?49, only one gap value Ngap,1 is defined and
DLNgap?Ngap,1. For 50?NRB?110, two gap values Ngap,1 and Ngap,2 are defined. Whether Ngap?Ngap,1 or
Ngap?Ngap,2is signaled as part of the downlink scheduling assignment as described in [3].
DLVirtual resource blocks of distributed type are numbered from 0 toNVRB?1, where

DLDLDLConsecutive NVRB VRB numbers compose a unit of VRB number interleaving, where NVRB?NVRB for Ngap?Ngap,1 DLand NVRB?2Ngap for Ngap?Ngap,2. Interleaving of VRB numbers of each interleaving unit is performed with 4
~~~DLcolumns and Nrow rows, where Nrow?NV, and P is RBG size as described in [4]. VRB numbers are RB/(4P)?P?~?written row by row in the rectangular matrix, and read out column by column. Nnull nulls are inserted in the last
~DLNnull/2 rows of the 2nd and 4th column, where Nnull?4Nrow?NVRB. Nulls are ignored when reading out. The
