Abstract: A system and method which permit the RNC to control purging of data buffered in the Node B. The RNC monitors for a triggering event, which initiates the purging process. The RNC then informs the Node B of the need to purge data by transmitting a purge command, which prompts the Node B to delete at least a portion of buffered data. The purge command can include instructions for the Node B to purge all data for a particular UE, data in one or several user priority transmission queues or in one or more logical channels in the Node B, depending upon the particular data purge triggering event realized in the RNC.

Abstract: A UE system implements dynamic link adaptation by adding or changing control information to notify a receiver which timeslots and codes are currently active and which timeslots should be avoided. The UE provides synchronization such that the receiver knows which timeslots and codes the UE has used to map the coded composite transport channel onto physical channels. The UE attempts to avoid the timeslots which are experiencing transmission difficulties, while attempting to utilize the timeslots which are not experiencing transmission problems.

Abstract: A wireless digital communication method for communicating between a base station and a plurality of user equipment mobile terminals (UEs) and employs adaptive modulation and coding (AM&C) to achieve improved radio resource utilization and provide optimum data rates for user services. Blocks of downlink (DL) data are received by the base station which requests downlink DL channel quality measurements only from those mobile terminals (UEs) with pending downlink transmissions. The UEs respond to the request by measuring and reporting DL channel quality to the base station, which then allocates resources such that the UEs will make best use of radio resources. The base station notifies the UEs of the physical channel allocation indicating the modulation/coding rate and allocated slots followed by transmission of blocks of downlink data which are transmitted to the UEs.

Abstract: Packet data from multiple types of data sources is stored. The data sources have reroutable and non-reroutable data. The multiple types of data sources flow into a multiuser channel in a wireless spread spectrum code division multiple access communication system. A queue for incoming data from each data source is provided. A backlog of data in the queue is tracked. Based on in part the tracked backlog, data flow from each of the data sources is limited. For each data source capable of rerouting packet data, packet data is selectively rerouted. For each data source not capable of rerouting packet data, packet data is selectively not sent.

Abstract: A scheduling mechanism controls packet data from multiple types of data sources. The data sources include reroutable and non-reroutable data. The multiple types of data sources flow into a multiuser channel in a wireless spread spectrum code division multiple access communication system. A queue associated with the multiuser channel has an input configured to receive incoming packet data from a plurality of data sources queues. The multiuser channel queue outputs the received packet data for transmission over the multiuser channel. Each data source queue uniquely associated with each data source and has an input configured to receive data from the queue's data source. Each data source queue capable of varying its capacity. The varying capacity of each data source changes based on in part an availability of the multiuser channel queue.

Abstract: Data is transmitted over a particular channel from a transmitter to a plurality of receivers. The particular channel is received at the plurality of receivers. Each of the receivers sends power control information to the transmitter based on a measured reception quality and a reception quality requirements of each receiver. The transmitter uses the power control information from each receiver and adjusts a transmission power level of the particular channel so that if any receiver requires an increase in the transmission power level to meet that receiver quality requirement, the transmission power level is increase and if all receivers exceed their quality requirement, the transmission power level is decreased.

Abstract: A wireless transmit receive unit (WTRU) for a code division multiple access (CDMA) telecommunication system utilizes a plurality of protocol layers including a physical layer and a medium access control (MAC) layer such that the MAC layer provides data to the physical layer via plurality of transport channels (TrCHs). Each TrCH is associated with a set of logical channels. The physical layer receives blocks of data for transport such that the transport blocks (TBs) includes a MAC header and logical channel data for a selected logical channel associated with a given TrCH. Each TB has one of a selected limited finite number of TB bit sizes. The logical channel data for each TB has a bit size evenly divisible by a selected integer N greater than three (3). The MAC header for each TB has a bit size such that the MAC header bit size plus the logical channel data bit size equals one of the TB bit sizes. A fixed MAC header bit size is associated with each logical channel for a given TrCH and is selected such that each fixed MAC header bit size equals M modulo N where M is an integer greater than 0 and less than N, i.e. each MAC header for a given TrCH has a bit offset equal to M.
