Abstract: Service data is transferred in a wireless communication system. A first service identification is transmitted for reception by a group of users of a cell in the system. The group of users does not include all of the users of the cell. Each of the group of users receives the service identification. Each of the group of users monitors for a second service identification being transmitted over a high speed downlink shared channel (HS-DSCH). The service data is transmitted over the HS-DSCH with the second service identification. Each of the group of users detects the second service identification and receives the service data of the HS-DSCH.

Abstract: A method for processing a received communication which includes periodic transmissions of a set of information segments. A first transmission of the set of information segments is received and processed to identify each of the segments as valid or invalid. The valid segments of the first set are then stored. Where all segments of the set are not stored, subsequent transmissions of the set of information segments are received and only those segments not previously stored are processed to identify each such segment as valid or invalid. The valid segments so identified are then stored. Subsequent transmissions are repeatedly received unless all segments of the set have been stored.

Abstract: The present invention is a user equipment (UE) which receives a communication signal over a physical reference channel using a reference channel receiver. An expected path loss is calculated using a path loss calculation device in response to the received communication signal. A signaling receiver receives an allocation of an uplink control channel including the amount of interference in the channel. Then, a power level calculation device, responsive to the path loss calculation device and the signaling receiver, determines an uplink power level based on the path loss and the interference level, whereby an uplink control channel transmission is initiated having the power level determined by the power level calculation device.

Abstract: A system and method for reducing the latency from timing deviation (TD) measurement to time advance (TA) adjustment. The invention uses a deterministic procedure to coordinate time advance (TA) commands and timing deviation (TD) measurements so that failed transmissions or mobile terminals signal propagation changes can be recognized and corrected much more rapidly. Radio resource efficiency is maximized by minimizing signaling overhead through effectively reducing the frequency of time advance commands. This is accomplished by using TA command signals which include a Connect Frame Number (CFN) to specify particular radio frames for time advance (TA) adjustment. The potential for timing deviation (TD) measurements to be incorrectly processed in conjunction with adjusting a physical reception window and calculating mobile termination location is minimized, without excessive command signaling requirements.

Abstract: A user equipment (UE) receives a reference signal over a physical reference channel using a reference channel receiver and obtains reference power levels from the reference signal. The interference level is obtained and a path loss is calculated in response to the reference signal. Transmit power is then determined for an allocated uplink control channel based, at least in part, upon said path loss and said interference level.

Abstract: A method for a base station to optimize radio resource utilization and adjust data rates in a wireless digital communications system. The base station communicates with 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: The present invention relates to efficient recovery of High Speed Downlink Packet Access (HSDPA) data following handover. The present invention discloses a method and system for the UE to perform a serial of actions in order to reduce the latency and potentially prevent loss of PDU transmission during the serving HS-DSCH cell change procedure. A new criterion is introduced for UE generation of the status report of RLC PDU. The UE generates status report of the PDUs as soon as possible following notification of the HS-DSCH cell change indicated by the RRC procedure to more efficiently recover source Node B buffered data. PDU status may be signaled for each AM RLC instance associated with the HS-DSCH transport channel. Furthermore, upon Inter Node B serving HS-DSCH cell change the SRNC may wait for PDU status report before initiating transmission of new data in target cell.

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