TLDR
In this article, a base station transmission apparatus for transmitting MAC (Medium Access Control) ID (Identification) information indicating a terminal to receive transmission packet data and length information of the transmitted packet data is described.Abstract:
A base station transmission apparatus for transmitting MAC (Medium Access Control) ID (Identification) information indicating a terminal to receive transmission packet data and length information of the transmission packet data in a mobile communication system for high-speed packet transmission, having an encoder for encoding a bit stream indicating the MAC ID information and generating coded symbols; a Walsh cover section for Walsh-covering the coded symbols from the encoder with a Walsh code based on the length information; and a Walsh spreader for spreading the Walsh-covered symbols from the Walsh cover section with a predetermined Walsh code.read more

Scheduled and autonomous transmission and acknowledgement
TL;DR: In this article, a traffic to pilot ratio (T/P) is used to allocate a portion of the shared resource, allowing a mobile station flexibility in selecting its transmission format based on T/P.
Patent
Congestion control in a wireless data network
TL;DR: In this article, a rate table (1000) is deployed, and a mobile station decreases or increases the transmission rate from one rate in the table to a lower or higher rate, respectively, in response to the busy signal.

Method and apparatus for controlling data rate of a reverse link in a communication system
TL;DR: In this article, the authors propose a data rate for transmission of the packets of data based on an arrangement of the data in a queue allowing for meeting the transmission deadline for each of the packet of data.
Patent
Operation of a forward link acknowledgement channel for the reverse link data
TL;DR: In this paper, a reverse supplemental channel (R-SCH) frame is received at a base station, and the base station then transmits an acknowledgement (ACK) signal if quality of the received SCH frame is indicated as being good and a negative acknowledgement (NAK) signal is transmitted only if the received data frame is indicating as being bad but has enough energy such that, if combined with energy from retransmission of the data frame, it would be sufficient to permit correct decoding of data frame.
