    摘要： 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, 0.67 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.

    摘要： 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.

    摘要： 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.

    摘要： The performance of closed loop transmit diversity (CLTD) systems may be improved, in accordance with aspects of the present invention, by encoding antenna control information fed back from a mobile station to a base station. As compared to prior art CLTD systems that send antenna control bits in unencoded feedback messages, encoding the antenna control information may result in reduced feedback delays and reduced transmission power. Further, in accordance with some aspects of the present invention, the antenna control bits may be fed back to the base station on a common feedback channel also used to feed back channel quality indication, thus reducing processing overhead.

    摘要： A method is described for transmitting information in a communication channel of a wireless communication system in which the communication channel is divided into a plurality of time slots of equal duration and each of the time slots is further sub-divided into multiple sub-slots or resource units. In one illustrative embodiment, the communication channel is divided into time slots according to a time division multiple access scheme. Each time slot is then further code-multiplexed into one or more sub-slots according to a code division multiple access scheme. Each of the sub-slots is therefore capable of carrying a separately coded transmission within the communication channel so that multiple simultaneous transmissions can occur in any given time slot.

    摘要： In a wireless communication system, there is a method of generating and transmitting signaling information from a user, where user control information may be appended as a header to a data block, and the data block and header may be encoded and transmitted as a signaling message from the user. In a method of scheduling a user for transmitting information, a signaling message, which may include user control information, is received from a user. A scheduling grant message that may include an allocated data rate may be transmitted in response to the received signaling message. The user control information may include one or more of buffer status information of the user, reverse pilot channel transmit power information and data related to a soft handoff (SHO) status of the user.
