    摘要： A variable length sequence number is used to identify data units in a communication channel. The sequence number associated with the most recent data that has been received successfully and the sequence number expected with the next new data message to be received are examined to determine the minimum size sequence number necessary to unambiguously identify to the transmitter incorrectly received data that must be retransmitted in a later message. The receiver provides the transmitter with the sequence number associated with the last successfully received byte of data and the sequence number associated with the next expected byte of data. The receiver communicates this information to the transmitter using a NAK control message. The transmitter then uses the sequence number of the next byte of data to be transmitted and the information received in the control message from the receiver to determine the smallest number of bits necessary to represent the sequence numbers for both data transmissions and the retransmission of data that was not received properly by the receiver.

    摘要： In the method, a receiver receives an indication of if the maximum number of sub-packet transmissions for conveying a data packet from a transmitter to the receiver has taken place. If the receiver has not properly received the data packet over a channel when this indication is received, then the receiver sends a non-acknowledgement response that causes the transmitter to re-schedule and re-send the data packet.

    摘要： Information is coded and segmented into a plurality of sub-packets. Each sub-packet contains identification information and a one-bit information status flag indicating whether the information is ‘new’ information or ‘continue’ information. The information to be transmitted is then applied to a scheduling algorithm that determines when the information is to be transmitted, how much information is to be transmitted and how many attempts at a successful transmission of the information is allowed. In this manner, the transmission of information can be performed in an asynchronous manner.

    摘要： An ARQ method using Incremental Redundancy that can be used in either synchronous or asynchronous communication systems. Information received by receiving equipment contains a one-bit NEW/CONTINUE flag indicating whether the received information is the beginning of new information or the continuation (or retransmission) of previously transmitted information. An ACK message is transmitted by the receiving equipment when such equipment receives information containing a NEW flag and successfully decodes such information. The receiving equipment also transmits an ACK message when it receives information containing a CONTINUE flag while it was waiting for NEW information. Thus, the method of the present invention allows for relatively quick recovery from misinterpretations of ACK/NACK messages and accommodates subscribers having different transmission requirements.

    摘要： A method of wireless communication. The method includes the step of transmitting at least one sub-frame associated with a first frame using at least a first wireless resource, such as a channelization code, a channelization tone and/or an allocated power transmit level. The method also includes the step of transmitting at least one sub-frame associated with a second frame. The sub-frame associated with the second frame may use at least a second wireless resource if a non-acknowledgement message associated with the first frame is received. However, if an acknowledgement message associated with the first frame is received, the sub-frame associated with the second frame may use at least the first and second wireless resources. Both first and second frames, and the sub-frames associated thereto may be assigned to a single user to reduce potential delay in real-time wireless services, such as voice, video or wireless gaming, for example.
