摘要： Downlink congestion is accurately detected and congestion control is more effectively provided without decreasing the system downlink capacity. The characteristics of the downlink transmission of the base station are monitored and used to selectively adjust a fast congestion control (FCC) alarm threshold value in each base station. A FCC relief action is initiated upon detecting the downlink power exceeding the FCC alarm threshold value, i.e., potential downlink congestion. The FCC relief action includes temporarily blocking data services in the system or rapidly decreasing the downlink transmit power of the packet data user's Dedicated Physical Channels in the base stations.

摘要： A method, system and apparatus for spreading physical channels using partly orthogonal multiple code trees. A portion of a first code tree is used to spread the physical channels. This first code tree is a combination of a channelization code sequence and a first scrambling code sequence. A portion of a second code tree is used to spread the physical channels that are remaining and were not spread using the first code tree. This second code tree is a combination of the channelization code sequence and a second scrambling code formed by modifying the first scrambling code. The portion of the second code tree used to spread the channels is orthogonal to the portion of the first code tree used. A plurality of other code trees could be formed using scrambling codes based on the modification of the first scrambling code.

摘要： A load control method is described herein that enables a base station to broadcast three downlink signals including a busy indicator, a maximum resource indicator and a minimum resource indicator to a mobile terminal. In response to receiving the downlink signals, the mobile terminal limits the utilization of a resource (e.g., bit rate, transmission power, power offset) it uses to transmit data to the base station. The mobile terminal may also send an uplink signal including a resource request to the base station. The base station can use the resource request to change the downlink signals if needed. It is with the proper use of these uplink/downlink signals that the behavior of the base station can be automatically optimized to the load situation.
