WIPO Patent Application WO/2010/067524
Kind Code:
A1
Abstract:
The purpose of this invention is to reduce power consumption associated with transmission path decoding and re-encoding in a radio relay station. A radio relay system comprises a radio station (1) and a relay station (2). The radio station (1) generates and transmits an RF signal (RF1) including transport data to a WPAN transmission path. The relay station (2) receives the RF signal (RF1) via the WPAN transmission path and generates and relays an RF signal (RF2) including the data received from the radio station (1) to a WWAN transmission path. The radio station (1) can exhibit, for the transport data to be transmitted to the WPAN transmission path, any one of two alternative transmission modes: one for performing a WPAN-compliant transmission path encoding and the other for performing a WWAN-compliant transmission path encoding. On the other hand, the relay station (2) can exhibit, for the encoded data received from the radio station (1), any one of two alternative relay modes: one for performing error correction code decoding and re-encoding and the other for skipping these processings.
