    摘要: A transmission device capable of reducing packet receiving errors and the number of retransmissions by improving error correction coding gain without increasing the amount of resources used in transmission. The transmission device (100) that transmits each bit of coded data constituted from systematic bits and parity bits in order for each transmission unit, and performs frequency puncturing to puncture, in units of symbols, data to be punctured in which each bit has been superimposed on a plurality of frequency domain symbols. A time puncturing unit (102) extracts transmission unit data from the coded data and a frequency puncturing unit (105) performs frequency puncturing in accordance with the ratio of parity bits to systematic bits included in the data.

    摘要: A wireless communication apparatus wherein the power consumption can be reduced. In this apparatus, a code block dividing part (101) divides a transport block, in which filler bits have been inserted, into a plurality of code blocks. A mapping control part (107) controls, based on both scheduling information, which is received from a scheduler (not shown) and indicative of physical channel resources to be used for code block transmission, and the number of filler bits which is received from the code block dividing part (101), the plurality of code blocks so that they will be mapped to the respective physical channel resources in such an order that a respective code block having a less number of filler bits will be mapped to a respective more forward physical channel resource. A mapping part (108) then maps, based on mapping information received from the mapping control part (107), data symbols, which are received from the modulating parts (106) of the respective ones of code block processing parts (102-1 to 102-C), to the physical channel resources.

    摘要: Provided are a radio transmission apparatus and a radio transmission method whereby the increase of number of signaling bits can be suppressed and further the flexibility of frequency scheduling can be improved. A notified RBG calculating unit (203) that adds a predetermined offset value of “1” or “−1” to one of the start RBG number and the end RBG number of allocated RBG number information (b′i) output by a scheduling unit (201), thereby calculating notified RBG number information (bi). An RBG total number setting unit (204) calculates the total number of RBGs, which is to be notified, by adding “1” to the total number of allocated RBGs. A notified information generating unit (205) applies the notified RBG number information (bi) and the notified total number of RBGs (Nrb′) to a predetermined formula, thereby generating and transmitting, to terminals, notified information (r).
