摘要： In an H-ARQ system, when the AN is receiving packet data traffic on the RL from an AT and is generating ACKs and NAKs according to the ability of the AN to properly decode such data, the AN gates-off a DRCLock bit within in a sub-packet duration in which an ACK is transmitted on the FL MAC channel. When it receives an ACK, the AT ignores the non-transmitted DRCLock bit in a current sub-packet duration, and assumes that the DRC channel is “good”. When the AN sends a NAK to the AT, it also sends the DRCLock bit. When the AT receives a NAK in a sub-packet duration, it reads and processes whatever DRCLock bit is received during that sub-packet duration. When no data traffic is transmitted on the RL traffic channel, corresponding DRCLock bits are not gated-off by the AN and are transmitted to the AT. The AT then processes the received DRCLock bits. In an alternative embodiment, transmission of DRCLock is totally eliminated.

摘要翻译： 在H-ARQ系统中，当AN正在从AT接收RL上的分组数据流量时，根据AN对这些数据进行正确解码的能力产生ACK和NAK，AN将关闭一个DRCLock位 在FL MAC信道上发送ACK的子分组持续时间。 当接收到ACK时，AT忽略当前子包持续时间内未发送的DRCLock位，并假定DRC信道为“良好”。 当AN向AT发送NAK时，它还发送DRCLock位。 当AT在子分组持续时间内接收到NAK时，它读取并处理在该子分组持续时间期间接收的任何DRCLock比特。 当在RL业务信道上没有传输数据业务时，相应的DRCLock比特不被AN门控，并被发送给AT。 AT然后处理接收到的DRCLock位。 在替代实施例中，完全消除了DRCLock的传输。

摘要： A closed loop power control based on receiving a continuous quality feedback is described. A main reverse link (RL) pilot is controlled by the quality feedback of a substantially continuous delay sensitive traffic stream, such as Voice-over-IP (VoIP), when such a stream is enabled. When such a stream is not enabled, the quality of a continuous RL overhead channel is used to control the pilot power. At the same time, the Traffic-to-Pilot Ratios (TPR) of contemporaneously transmitted delay sensitive data streams are independently adjusted based on a quality feedback associated with each such data stream.

摘要： In a method of canceling interference, a base station selects a known highest data rate user transmission from a received first signal containing a group of user transmissions. The known highest rate user transmission may be configured as one or more frames, each frame including a control preamble and a plurality of encoded sub-frames. The control preamble and encoded sub-frames may be decoded, and the decoded sub-frames may be used for removing interference caused by the known highest rate user transmission to all remaining transmissions of the group.
