Abstract: A rate feedback and adaptation scheme or system uses a rate of rate feedback asymmetrical with the rate of data rate adaptation. In particular, the rate adaptation system provides a rate of rate feedback slower than the rate of rate adaptation. Thus, by allowing the base station to change the data rate more frequently than the individual wireless units reports the rate information, the rate adaptation system can provide improved flexibility and more efficient use of wireless resources while reducing the processing and transmission overhead required to report the rate information. For example, every 3 slots, a wireless unit can calculate and report a rate for the wireless unit to use on a shared channel to send data. The base station receives the rates from the wireless units seeking to send data over the shared channel and selects a wireless unit to use the shared channel. If the base station can adapt the data rate every slot, the base station can adapt the data rate in accordance with a rate reported by another wireless unit, thereby improving system performance. Because of the small slot duration (for example, .67 microseconds), the relatively reduced rate of reporting should not adversely effect system performance since it is highly unlikely that the achievable data rate will change over a period of a slot under most operating conditions.

Abstract: A prior message is used to identify groups of messages that may be used for transmission. The groups of messages contain different numbers of messages, so as a result, messages from smaller groups may be represented using less bits than messages from larger groups. The smallest group contains messages with the highest probability of being sent; therefore, the probability of using a message represented by a smaller number of bits is maximized. Messages from different groups are transmitted at different power levels to enable a receiver to determine the message group. As a result, a receiver uses the prior message, the power level associated with a received message and the received message bits to identify a message.
In another embodiment, a known or current system state, rather than a prior message, is used to identify groups of messages that may be used for transmitting or receiving.

Abstract: The capacity of a reverse link is improved by realizing a scheme to effect sharp changes in pilot channel transmit power (PCTP) and data channel to pilot power ratio (DCPR), coordinated with the start of the data channel transmission. The change in pilot power and data channel to pilot power ratio is also applicable to mobiles that use multiple pilots and/or multiple antennas at the transmitter and/or receiver.

Abstract: A method of generating coded user ID information that is combined with CRC codes and the result is appended to signaling information. The CRC codes are generated from the signaling information. The resulting codeword is transmitted over shared signaling channels to various users of a communication system. The resulting codeword is such that the likelihood of users attempting to decode codewords not intended for them is significantly reduced.

Abstract: A transport channel multiplexing system provides improved use of wireless resources in a shared data channel system. For example, the transport channel system reduces the amount of transport format information required for using a shared data channel, such as the actual number of packet data units in a transport channel of the shared data channel. Additionally, by scheduling or multiplexing coded sub-blocks from one or more transport channels over the shared data channel, the transport channel multiplexing system can provide improved integration with other important features, such as incremental redundancy, fast adaptation to channel conditions and transport channel dependent quality of service (QOS) control, to provide improved system performance.

Abstract: An uplink and downlink channel structure supports a shared downlink data channel. The new structure accommodates advanced physical and Medium Access Control (MAC) layer techniques, such as incremental redundancy (IR), fast adaptation to channel conditions, and multiple input multiple output (MIMO) antenna configuration. The proposed changes are intended to lead to a downlink structure that achieves higher spectral efficiency for the packet oriented services over then shared downlink channel. Additionally, the new structure uses the base station transmit power information and of the channelization (OVSF) code space more efficiently.
