Abstract: An apparatus and method for transmitting a signal using a bit grouping method in a wireless communication system is disclosed. Interleaved subblocks are maintained, and output bit sequences are modulated in due order after bit grouping and bit selection. The bit grouping method is advantageous in that bit reliability is uniformly distributed.

Abstract: A method for receiving data at different frequencies includes receiving a first transmission packet including data at a first carrier frequency, and receiving a second transmission packet comprising data at a second carrier frequency. The method further includes maintaining communication with transmission entities which transmit the first and second transmission packets, and identifying reception quality of the first and second transmission packets. In addition, a method for retransmitting subpackets includes transmitting a first subpacket of a packet transmission from at least two transmitting entities. Upon receiving a non-acknowledgement NACK generated responsive to the first subpacket, the method further includes alternating transmission of subsequent subpackets from different transmitting entities. Upon receiving an acknowledgement ACK generated responsive to any subpackets of the packet transmission, the method further includes transmitting a first subpacket of a new packet transmission.

Abstract: Mechanisms for improving the proposed high rate packet data (HRPD) system are provided. Approaches proposed are including PilotGroupID in the sector parameter message to convey the pilot group information, encoding to enable shortened NeighborList messages, improvements on RoutUpdateRequest message for request updates on multiple carriers, inclusive of the channel record of the reference pilot in the RouteUpdate message when the message sent in the connected state, using pilot drop timer of a Candidate Set pilot as a trigger for sending RouteUpdate, encoding the TrafficChannelAssignment message to shorten the message in certain situations, limiting the usage of auxiliary DRC cover in some situations to avoid confusion in determining the serving sector and processing OverheadMessages.
