Abstract:
1. In reverse link packet data transmission on MAC channel with period between a base station and a mobile station using hybrid automatic repeat request (HARQ), a method of transmitting control information, comprising: transmitting reverse power control information in a first slot section to the mobile station; making a decision of whether to increase or decrease a data rate of a reverse link packet using the control information received from the mobile station and transmitting rate control information corresponding to the decision in a second slot section, wherein the rate control information is represented by an RCB (rate control bit) symbol and the second slot section corresponds to (T-FrameOffset) mod8 =2 and 3, wherein if the RCB symbol indicates an increment of the data rate of the reverse link packet, it is mapped to ‘1’, wherein if the RCB symbol indicates a decrement of the data rate of the reverse link packet, it is mapped to ‘−1’, and wherein if the RCB symbol indicates ‘unchanged’ of the data rate of the reverse link packet, it becomes ‘gate-off’; and decoding a sub-packet received from the mobile station and transmitting information of a success or failure result of decoding the sub-packet in a third slot section.
