Abstract
A method and apparatus for transmitting a broadcast physical layer packet in a mobile communication system supporting multi-slot transmission and hybrid Automatic Repeat Request (H-ARQ) are provided. The method comprises initially transmitting the broadcast physical layer packet according to a fixed transmission format for at least one first slot interval and retransmitting the broadcast physical layer packet for at least one second slot interval using a variable transmission format different from the transmission format used in the first slot interval.
Claims16
A method for receiving a broadcast physical layer packet in a mobile communication system supporting multi-slot transmission and hybrid Automatic Repeat Request (H-ARQ), the method comprising:
- receiving, by a reception unit, transmission format information for the broadcast physical layer packet through a broadcast overhead message;
- receiving, by the reception unit, the broadcast physical layer packet that is initially transmitted in a fixed transmission format for at least one first slot interval, according to the transmission format information;
- and
- receiving, by the reception unit, the broadcast physical layer packet that is retransmitted in a variable transmission format different from the transmission format used in the first slot interval for at least one second slot interval, according to the transmission format information.
An apparatus for receiving a broadcast physical layer packet in a mobile communication system supporting multi-slot transmission and hybrid Automatic Repeat Request (H-ARQ), the apparatus comprising:
- a radio frequency (RF) unit for converting a broadcast physical layer packet received over the air into a baseband signal;
- a reception unit for receiving the broadcast physical layer packet according to a transmission format used for initial transmission and retransmission, and restoring the received broadcast physical layer packet to an original signal;
- and
- a controller for controlling operations of the RF unit and the reception unit so as to, upon receipt of a broadcast overhead message including transmission format information for the broadcast physical layer packet, receive the broadcast physical layer packet that is initially transmitted in a fixed transmission format for at least one first slot interval, according to the transmission format information, and to receive the broadcast physical layer packet that is retransmitted in a variable transmission format different from the transmission format used in the first slot interval for at least one second slot interval, according to the transmission format information.
