The present invention provides a method for handling potentially corrupted frames. The method includes receiving a frame having a first sequence number, determining, based on the first sequence number, whether the frame is potentially corrupted, and determining a number of received potentially corrupted frames in response to determining that the frame is potentially corrupted. The method also includes determining whether to drop the potentially corrupted frame based on the number of received potentially corrupted frames.

Method and apparatus for handling potentially corrupt frames

A method of communicating at least one data burst using an assigned radio configuration. The assigned radio configuration is chosen from one of at least two radio configurations by examining which radio configuration supports a higher data transmission rate. This examination is determined by calculating the data transmission rate for the data burst(s) base on a power level and Walsh code for each of the radio configurations.

Method of data burst transmission

A mobile terminal selects a transmission rate for the reverse common signaling channel in response to at least one mobile-terminal-measured metric that is associated with the RF conditions of the channel. The mobile terminal is provided with information, where the information takes the form of at least one threshold level that the one or more measured metrics are compared with, to determine the rate at which at which the mobile terminal should transmit.

The probability of a time out and the resulting waste of channel capacity in a communication system is decreased by controlling the length of the time out period so as to minimize the number of time outs that occur. The length of the time out is based on the sum of the average channel delay and four times the deviation in the channel delay. A delay is introduced into the communication channel so as to increase the deviation in the channel delay. This results in an increase in the length of time required for a time out. As a result, the number of time outs is drastically decreased which in turn decreases the number of wasteful ramp up times that results in a more efficient use of channel capacity.

Wireless data transmission using time out control

The Radio Link Protocol framing system provides the mobile wireless station set with high speed data transmission capability by using the Dedicated Control Channel, which comprises a stream of 20 msec frames, to carry a single 18 byte Radio Link Protocol frame and the Supplementary Channel, which comprises a stream of 20 msec frames, to carry many 18 byte Radio Link Protocol frames to accommodate high-speed bursts of data. The Radio Link Protocol framing system packs the Radio Link Protocol frames within the Supplementary Channel (SCH-RLP frames) to maximize the data processing efficiency. The Radio Link Protocol framing system functions to package the subscriber's data into predetermined frame format consisting of Core Units, which are packed, as needed, into one SCH-RLP frame. The data capacity is limited solely by the Supplementary Channel burst capacity. By simply computing the Cyclic Redundancy Check bits to validate the accuracy of the data contained within a SCH-RLP frame enables the system to copy the data directly from the SCH-RLP frame to data receive buffers. Both sequential and non-sequential frames can be incorporated into a single SCH-RLP frame. The Core Unit is the common divisor of both the Dedicated Control Channel and the Supplementary Channel. The Dedicated Control Channel supports transmission of a full frame of 9.6 Kbps, while the Supplementary Channel supports data transmission speeds of 9.6 Kbps and higher.

A method to dynamically assign data rates, for digital data transmission in wireless communication systems, which are just sufficient to meet the needs of the use is presented. The method monitors the data traffic and anticipates when the assigned data rate is inadequate to support the data traffic resulting in a loss of data or when the assigned data rate is more than necessary to support the data traffic and results in inefficient usage of system resources.

Method of queue length based burst management in wireless communication systems

A method is described to reduce the time required to assign the burst transmission parameters in a wireless communication system by autonomously sharing transmission and reception information among the components of the network. Information is autonomously provided from a remote subnetwork element to a controlling network element so the controlling network element may use the information to dynamically assign and update burst transmission parameters.
