Abstract:
PROBLEM TO BE SOLVED: To provide a method and an apparatus for augmenting a physical layer ARQ in a wireless data communication system. SOLUTION: A system and various methods and an apparatus for efficient communications of data across various protocol layers are disclosed. A control and transceiver system (1400) is arranged for determining a data rate control value and for transmitting the maximum number of time slots allowed for transmission of a physical layer packet of data (510). After detecting a normal termination of transmission, the decoding thresholds (401, 402) are adjusted so as to decode a positive acknowledgment message, and decoding of acknowledgment channel (340) is repeated using the adjusted thresholds (401, 402). Retransmitting the physical layer packet of data at least one more time is executed after based on whether or not the repeat of decoding of the acknowledgment channel (340) produces a negative acknowledgment message.

Abstract:
PROBLEM TO BE SOLVED: To increase the throughput in a sector.SOLUTION: Upon successful decoding of a first set of slots of a first data packet, an access network (AN) can send an acknowledge message (ACK) to an access terminal (AT) to indicate that the AN has successfully decoded the data received in the first set of slots of the first data packet. Upon unsuccessful decoding of the first set of slots of the first data packet, the AN can send a negative acknowledge message (NAK) to the AT to indicate that the AN has not successfully decoded the data received in the first set of slots of the first data packet. Based upon receipt of the NAK, the AT can resend the data by sending a second set of slots of the first data packet containing redundant data. Based upon receipt of the ACK, the AT can send a first set of slots of another packet.
Abstract:
An apparatus and method for adjusting a power control setpoint for a power control mechanism with a first state and a second state in a wireless communication system. The method comprises: determining the state of the power control mechanism; when the state of the power control mechanism is the first state, adjusting the power control setpoint in accordance with a first adjustment scheme; and when the state of the power control mechanism is the second state, adjusting the power control setpoint in accordance with a second adjustment scheme.
Abstract:
A method and apparatus that determines how much power to allocate to each of a plurality of reverse link power control (RLPC) Channels to be transmitted from a base station, based upon data rate control (DRC) messages transmitted to the base station. Historical information is used to determine the quality of the Forward Link over which the RLPC is to be transmitted. If the history of the DRCs received indicates that the remote station to which the RLPC Channel is to be directed has not transmitted a DRC recently, then the base station allocates power to the RLPC Channels based upon information provided to the base station in DRCs that were received by the base station, but that were directed to other base stations. Accordingly, the base station can allocate power among the RLPC Channels without having received explicit information as to the quality of the Forward Link between the base station and every remote station intended to receive the information on the RLPC Channels.

A system (100) and various methods and apparatus for efficient communications of data across various protocol layers are disclosed. A control and transceiver system (1400) configured for determining a data rate control (DRC) value and for transmission a maximum number of time slots allowed for transmission of a physical layer packet of data (510). After detecting a normal termination of transmission, the decoding thresholds (401, 402) are adjusted for decoding a positive acknowledgment message, and repeating decoding of acknowledgement channel (340) with the adjusted thresholds (401, 402). Retransmitting the physical layer packet of data at least one more time after based on whether the repeat of decoding of the acknowledgment channel (340) produces a negative acknowledgment message. The retransmission may be conditioned upon a throughput level of communications between the base station and the mobile station.

Abstract:
An Access Terminal can send a first set of slots of a first packet to an Access Network, wherein the first set of slots is a subset of a plurality of slots of the first packet and includes one or more slots. Then, the Access Terminal can gate off for a predetermined period of time after sending the first set of slots of the first packet and before sending a next set of slots, wherein the predetermined period of time is determined by the number of slots in the first set of slots of the first packet. Finally, the Access Terminal can determine the next set of slots to send based on whether an ACK or a NAK corresponding to successful or unsuccessful decoding, respectively, of the first set of slots of the first packet has been received from the Access Network and send the next set of slots after the predetermined period of time.
