Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for link quality feedback in wireless communication. SOLUTION: The present invention relates to a method and apparatus for providing link quality feedback to a transmitter (32, 34). In one embodiment, a periodic link quality message is transmitted on a gated channel, while continuous differential indicators are transmitted. Between quality messages, the differential indicators track the quality of the link. The periodic quality messages provide synchronization to the transmitter and receiver (36, 38). A coding is applied to the feedback information identifying the transmitter. In one embodiment, a remote station includes a differential analyzer (212) to determine the change in successive channel quality measurements. In an alternate embodiment, link quality feedback information is gated according to channel condition. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: In a wireless communication system (50) a method for combination transmission of packet data and low delay data. In one embodiment a parallel signaling channel provides a message to receivers (56, 58, 60) indicating a target recipient of packet data. The message also identifies the transmission channels used for packet data transmissions. Each receiver may then selectively decode only packets where the message identifies the receiver as a target recipient. The data packets stored in a buffer are ignored if the target recipient is another mobile unit. In one embodiment, the message is sent concurrently with the data packet on a parallel channel. In one embodiment, the message is punctured into the high rate packet data transmission.

Abstract: Systems and methods for controlling the power level for a mobile station during periods when no data is being transmitted by the mobile station. In one embodiment, data is intermittently transmitted from a mobile station to a base station on a reverse-link traffic channel. When data is being transmitted on the traffic channel, the transmitted data is used by the base station to perform power control operations (e.g., incrementing or decrementing the mobile station's power level, based upon comparison of a received SNR to a target SNR). When no data is being transmitted on the traffic channel, a "zero-rate indicator" is transmitted on the rate indicator channel. The zero-rate indicator is used by the base station to perform power control. Power control based on the zero-rate indicator may use velocity profiles, reliability metrics or other techniques to control adjustment of the power level.

Abstract: A method and apparatus for improving the transmission of an information signal having message information. A received information signal is formed from an information signal transmitted through an information channel. The received information signal has signal noise. The message information is removed from the received information signal to provide a symbol sequence that is then applied to a first filter to provide a first filtered signal. The power of the first filtered signal is determined and applied to a second filter to provide a second filtered signal representative of the signal noise of the received information signal.

Abstract: Techniques for transmitting voice/data and packet data services such that packet data transmissions have less impact on voice/data transmissions. In one aspect, voice/data and packet data can be multiplexed within a transmission interval such that the available resources are efficiently utilized. In another aspect, the amount of variation in the total tansmit power from a base station is controlled to reduce degradation to transmissions from this and other base stations. In a specific method for concurrently transmitting a number of types of data, a first data type (e.g., voice, overhead, and some data) and a second data type are respectively processed in accordance with first and second signal processing schemes to generate first and second payloads, respectively. First and second partitions are then defined in a transmission interval. The first and second payloads are time multiplexed into the first and second partitions, respectively, and the multiplexed payloads are transmitted.

Abstract: A method for wireless communications where a control packet is not transmitted for all transmissions of a new data packet. A control packet is only sent with a retransmission of a data packet where the previously transmitted data packet is not completely received. The control packet contains information related to a previously transmitted data packet. The previously transmitted data packet and the retransmission data packet are derived from common data. The common data is derived based on the information related to the previously transmitted data packet, wherein the previously transmitted data packet and the retransmission data packet are associated with a series of data packets.
