摘要： A method is described for adapting the size of data for a future Transmission Time Interval (TTI) by a User Equipment (UE), wherein all the Media Access Control (MAC)-d flows are grouped and stored in different lists based on a type of grants associated with the MAC-d flows, ability of a MAC-d flow to be multiplexed with another MAC-d flow from a list, and data availability in a logical channel mapped onto a MAC-d flow in the current TTI. The E-TFC is then selected by the UE for the future TTI using the MAC-d flow having the highest power offset in a consolidated list including the grouped MAC-d flows. The size of the data is thereby adapted using the selected E-TFC. Further disclosed is a method for generating RLC PDUs by the UE for the future TTI using the variation in the scheduled grant for the UE and the size of the data adapted for the future TTI.

摘要： A method and apparatus for performing measurements in a multi-carrier environment are provided. In the method, a request to perform measurements on a frequency corresponding to one of at least one frequency band is received from a base station. It is determined whether a compressed mode is to be applied on the frequency corresponding to the one of the at least one frequency band based on capabilities of a user equipment. If so, the compressed mode is applied on the frequency corresponding to the one of the at least one frequency band so that measurements can be performed on the frequency corresponding to the one of the at least one frequency band without interrupting data activity on the remaining frequency bands. Otherwise, measurements are performed on the frequency corresponding to the one of the at least one frequency band without applying the compressed mode.

摘要： Determination of transmission power control commands in a UE by combining TPC commands received during DTX/DRX modes. The combining is done on those TPC commands which are received on different radio links after ignoring TPC commands which might be received in a DL slot overlapping with no UL transmission. The UE thus uses the combined TPC commands as derived at the time of entry into DTX for the second UL DPCCH preamble transmission which leads to increase in link reliability and subsequent conservation of power by the UE. The UE uses the same power as derived in the previous slot for resumption of transmission when all the TPC commands, received in the DL slot overlapping with no UL transmission, are UP. TPC commands for the transmission of the 2nd DPCCH preamble at transmission resumption is determined by combining stored TPC commands from each of the radio links that were received by the UE while entering into DTX gap and said TPC commands could not be applied with the newly received TPC commands.
