Fig. 1 shows a kind of schematic diagram of the generation transmission block of method for transmission processing provided in an embodiment of the present invention.
As shown in Figure 1, the treatment process of physical layer channel mainly includes generating transmission block, modulation and resource impact etc. three A subprocess.
The embodiment of the present invention can specifically be applied to uplink transmitting scene or downlink transfer field using in a variety of transmitting scenes Scape.
In uplink scene, transmitting terminal can be UE (User Equipment, user equipment), and receiving end can be network Side apparatus is transmitted as example below with uplink and is illustrated such as base station (eNB).
In subprocess 1, UE symbiosis carries the bit number of transmission in need at two transmission blocks on each transmission block, The effective number of bits carried on each transmission block is denoted as TBS.
Before determining effective number of bits, the size of transmission block need to be determined.
UE is according to NPRB and effective TBS index (ITBS, TBS Index), transmission can determine that by resource impact relation table The size of block.
Wherein, NPRB is the number for the resource block (RB, Resource Block) that each UE can be used for data transmission, and can Know that modulation coding scheme indexes (I in advanceMCS, Modulation and Coding Scheme Index), according to IMCS, pass through Inquire IMCSWith ITBSRelation table can determine ITBS。
In subprocess 2, the transmission block being generated to successively is scrambled, modulates mapping and layer mapping processing.Specifically may be used Pass through the I known in advanceMCSDetermining modulation system is adjusted.
In subprocess 3, to receiving, through layer mapping, treated that data successively carry out precoding, physical resource maps It is handled with OFDM symbol generation.
