    Abstract: PROBLEM TO BE SOLVED: To facilitate transmitting control data over one or more scrambled logical channels.SOLUTION: Control data values are easily multiplexed over a single physical control channel at least in part by dividing the control channel into one or more logical channels. The physical control channel can have a corresponding Walsh space for transmitting a number of bits, or representation thereof, and the Walsh space can be divided among the logical control channels. Additionally, the logical control channels and/or physical channel are scrambled according to an identifier of a mobile device (such as a MAC ID) to differentiate the data on the channel. Furthermore, a sector identifier is used to scramble the data where the sector is ascertainable.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for sending acknowledgement (ACK) and/or other control information with a configurable timeline.SOLUTION: A receiver may have limited processing resources and may need different amounts of time to process different amounts of data. The receiver may send ACK information earlier (or later) if less (or more) receive processing time is required. In one design, the receiver may receive a transmission of data in accordance with a grant, decode the received transmission to recover the data, and determine ACK information on the basis of decoding result. The receiver may determine a frame to send the ACK information on the basis of the grant. The determined frame may be one of multiple frames available for sending the ACK information.

    Abstract: PROBLEM TO BE SOLVED: To provide communication systems and methods that minimize repetition of data packets in the presence of supplemental resources.SOLUTION: Control channels not engaged in transmission of control messages are dynamically allocated to carry traffic data. Data packets that comprise the traffic data are processed in accordance with various schemes and the generated subpackets are transmitted so that an entire subpacket is transmitted on a traffic channel while a corresponding coded portion of the last subpacket is transmitted on available supplemental channels. If the subpacket is decoded correctly, an acknowledgement (ACK) message is sent, otherwise a negative acknowledgement (NAK) message is transmitted.

A delta value can also be communicated as feedback to a serving access point to allow the access point to assign transmission resources for the terminal.
