Abstract
A radio frequency (RF) unit, a digital unit, and methods of transmitting and receiving data in a wireless communication system are provided. The digital unit may include: a transceiver configured to receive compressed data from an RF unit, a processor configured to divide a frequency domain and a time domain into a plurality of blocks, set a compression parameter to be applied to each of the plurality of blocks, and expand the received data in units of the blocks based on the set compression parameter, and a memory storing the compression parameter.
Claims10
A digital apparatus comprising:
- a transceiver;
- and
- a processor coupled with the transceiver and configured to:
- divide a frequency domain and a time domain into a plurality of blocks based on scheduling information shared between the digital apparatus and a radio frequency (RF) apparatus,
- receive, from the RF apparatus, at least one signal in portion of each of the plurality of blocks,
- set a compression parameter to be applied to each of the plurality of blocks among a plurality of compression parameters, based on a characteristic of the at least one signal, wherein the plurality of compression parameters are pre-configured between the digital apparatus and the RF apparatus, and
- expand compressed data received from the RF apparatus in units of the blocks based on the set compression parameter.
