communication systems. The disclosed invention is a method of sub-packet
adaptation based on the data rate. In particular, the size of a sub-packet is
adapted to the data rate at which the sub-packet is to be transmitted. The
disclosed invention further adapts the sub-packet size to the data rate in a
format that would allow such size-adapted sub-packet to be soft combined
with another sub-packet of a same or different size. The size-adapted sub-
packet may be transmitted prior to or after the other sub-packet. In one
embodiment, the disclosed invention comprises the steps of channel coding
an encoder packet to produce a channel-coded encoder packet; and
puncturing and/or repeating the channel-coded encoder packet to produce an
encoder sub-packet having a size based on a size of the encoder packet and a
data transmission rate at which the encoder sub-packet is to be transmitted
(Specification 1-3).
Representative claim 1 is illustrative:
1. A method of transmitting data comprising the steps of:
channel coding an encoder packet to produce a channel coded encoder
packet; and
puncturing and/or repeating the channel coded encoder packet to
produce a first encoder sub-packet having a first size based on a size of the
encoder packet and a first data transmission rate at which the first encoder
sub-packet is to be transmitted, wherein the first data transmission rate is
different from and based on a data rate for transmitting the first encoder
subpacket indicated in a first rate indication message from a receiver.
