US 11,121,830 B2 · Communication system having a central aggregation device and a remote device

Abstract

Provided is a communication system that can sustain a reduction in delay in FFT/IFFT processing by code blocking user data, even in a case where the functions of upper layers such as a MAC scheduler and the function of the radio physical layer are implemented separately. In a radio base station (communication system) including a central aggregation device 210 and a remote device 220, the central aggregation device 210 transmits code blocks in a number necessary for generating an OFDM symbol as a piece of data to the remote device 220, the code blocks being produced by dividing user data into units of encoding processing.

Dependent claims

A communication system comprising:

a first communication device;
and
a second communication device,
wherein the first communication device includes a transmitter and a processor,
wherein the processor determines a number of data blocks of encoding processing necessary for generating a single OFDM symbol by the second communication device,
wherein the processor divides user data into the number of data blocks,
wherein the transmitter transmits the number of divided data blocks to the second communication device,
wherein the second communication device includes a controller that generates OFDM symbols by using the number of divided data blocks, and
wherein the transmitter transmits the plurality of divided data blocks based on information indicating an order or a range of a certain two or more number of the OFDM symbols to be generated.
