Abstract

The embodiment of the invention discloses an obtaining method and apparatus for a transport block size (TB Size). The method and the apparatus are used for lowering the cost or the power consumption cost for TB Size obtaining and are suitable for a mobile terminal and internet terminal equipment, wherein the mobile terminal and the internet terminal equipment are sensitive to the cost and the power consumption index. According to the embodiment of the invention, the obtaining method comprises the following steps that: all TB Sizes with unequal numerical values are extracted from a TB Size table; all the TB Sizes with unequal numerical values are stored into an internal memory or an external register; and a TB Size of a current frame is obtained according to control information and all the stored TB Sizes with unequal numerical values, wherein the control information includes resource distribution information, a modulation and coding scheme (MCS) index, a channel quality indicator (CQI) index, an orthogonal frequency division multiplexing (OFDM) symbolic number occupied by a physical downlink control channel (PDCCH).

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for acquiring the size of a transmission block. Background technique [0002] In the long-term evolution (LTE, Long Term Evolution) and subsequent evolution systems, one of the methods for obtaining the transport block size (TB Size, Transport Block Size) in the prior art is to first obtain the transport block size index (TBS index, Transport Block Size Size index) and the number of resource blocks allocated to the user, and then according to the TBS index and the number of resource blocks allocated to the user from Table 7.1.7.2.1-1 Transport block size table (dimension 27×110) in 3GPP TS36.213 Get the TB Size of the user's current frame. [0003] The inventor of the present invention found in the process of realizing the present invention: since the number of elements in Table 7.1.7.2.1-1 in TS36.213 is 27×110=2970 in total, 4 bytes ( When B...
