摘要： Techniques for reporting channel quality indicators (CQIs) are described. Data activity at a receiver may be determined, and CQI reporting by the receiver may be adjusted based on the determined data activity. In one design, CQI reporting may be enabled for a time window around each expected packet arrival for a periodic or quasi-periodic transmission and may be suspended outside of the time window. In another design, CQI reporting may be varied based on ACK/NACK feedback. In yet another design, CQIs may be sent at a first rate when data activity is not detected and at a second rate faster than the first rate when data activity is detected. In yet another design, CQIs may be sent only during discontinuous transmission (DTX) ON periods when data activity is not detected and may be sent during both DTX ON and OFF periods when data activity is detected.

摘要： 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.

摘要： First and second transmission links are established with a remote station. An information signal is encoded to provide an encoded information signal having more bits than the information signal. First and second transmission signals are provided wherein each transmission signal has bits selected from the encoded information signal. Each of the first and second transmission signals is transmitted to the remote station by way of a respective one of the first and second transmission links. The remote station receives and combines the first and second transmission signals transmitted by the remote station to provide a combined encoded signal. The combined encoded signal is decoded by the remote station to provide the information signal. The first and second transmission links can be formed between the remote station and a single base station or between the remote station and two separate base stations.

At least one of first and second high transmit power regions are separated into a plurality of high transmit power subregions. The high transmit power subregions of the plurality of high subregions are shifted by time offsets of differing durations to provide a plurality of time offset subregions. First and second low transmit power regions are also provided. At least one of the first and second low transmit power regions is also separated into a plurality of transmit power subregions and the low transmit power subregions are shifted by time offsets of differing time durations.

摘要： Methods and apparatus are presented for dynamically controlling the re-transmission scheme of acknowledgment signals. A source transmits a first data packet over a slot s1. If channel conditions are favorable, source transmits a second data packet over slot s2, which precedes the reception of any acknowledgment signals. A destination receives first data packet over slot d1 and second data packet over slot d2. Destination decodes first data packet during slots d2 and d3, and second data packet over slots d3 and d4. Destination transmits an acknowledgment signal (ACK1) associated with first data packet during slot d4. Rather then transmitting the second ACK1 associated with first data packet over slot d5, destination preempts this slot with an acknowledgment signal ACK2, which is associated with second data packet transmitted by source. Hence, destination is configured to overwrite the repetition of a previous acknowledgment in order to transmit a new acknowledgment.

摘要： Techniques for performing duplicate detection and re-ordering for a HARQ transmission are described. For duplicate detection, a receiver determines whether a decoded packet x for an ARQ channel y is a duplicate packet based on packet x and a prior decoded packet for ARQ channel y. For re-ordering, the receiver determines whether an earlier packet is still pending on any other ARQ channel based on prior decoded packets for the ARQ channels and forwards packet x only if there are no pending earlier packets. There are no pending earlier packets on another ARQ channel z if (1) a decoded packet was received on ARQ channel z at a designated time or later or (2) a decoded packet was not received on ARQ channel z within a time window from current time.

摘要： Methods and apparatus are presented for improving the feedback of channel information to a serving base station, which allows a reduction in the reverse link load while allowing the base station to improve the forward link data throughput. Over a channel quality indicator channel, three subchannels are generated; the re-synch subchannel, the differential feedback subchannel, and the transition indicator subchannel. The information carried on each subchannel can be used separately or together by a base station to selectively update internal registers storing channel conditions. The channel conditions are used to determine transmission formats, power levels, and data rates of forward link transmissions.

摘要： 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.
