    Abstract: método e aparelho de comunicação sem fio para sustentar reconfiguração de parâmetros de controle de links de rádio. é descrita uma série de métodos e aparelhos de comunicação sem fio para sustentar reconfiguração de parâmetros de controle de links de rádio (rlc). é gerada uma mensagem de reconfiguração de controle de recursos de rádio (rrc) que indica que uma unidade de rlc em uma unidade de transmissão e recepção sem fio (wtru) ou uma rede de acesso via rádio terrestre universal (utran) deverá ser reconfigurada de sustentar unidades de dados de protocolo (pdus) de rlc com tamanho flexível para sustentar pdus de rlc com tamanho fixo. caso um elemento de informação (ie) "restabelecimento de rlc de um lado" esteja presente na mensagem de reconfiguração de rrc, apenas um subconjunto do lado de recepção na unidade de rlc é restabelecido. caso contrário, o subconjunto do lado de recepção e um subconjunto do lado de transmissão na unidade de rlc são ambos restabelecidos. pdus de rlc com tamanho flexível podem ser descartadas e pode ser transmitida uma mensagem que indica as pdus de rlc com tamanho flexível descartadas. as pdus de rlc com tamanho flexível podem ser modificadas de forma a corresponderem a um conjunto de tamanhos previamente definidos.

    Abstract: A method and a wireless transmit receive unit, WTRU, for performing measurements for cell reselection are disclosed. Priority information is received via a system information broadcast, wherein the priority information is indicative of cell reselection priority information for an inter-radio access technology, RAT, cell associated with a candidate RAT. A relative priority is determined of the inter-RAT cell associated with the candidate RAT with respect to a current cell associated with a current RAT based on the priority information. Furthemore, cell reselection measurements are performed on the inter-RAT cell in the candidate RAT, wherein the cell reselection measurements are performed based on at least one of the inter-RAT cell associated with the candidate RAT having a higher relative priority than the current cell associated with the current RAT, or a quality of the current cell being less than or equal to a predetermined threshold if the inter-RAT cell associated with the candidate RAT does not a have a higher relative priority than the current cell associated with the current RAT.

    Abstract: A WIRELESS TRANSMIT RECEIVE UNIT (WTRU) (110) IS CONFIGURED TO OPERATE IN AN HIGH SPEED DATA PACKET ACCESS (HSDPA) MODE IN A CELL AND/OR STATE AND TO CLEAR HSDPA RESOURCES WHEN MOVING OUT OF THE CELL AND/OR STATE. THE WTRU (110) IS CONFIGURED TO CLEAR HSDPA RESOURCES WHEN CONDITIONS TO PERFORM HIGH SPEED DOWNLINK SHARED CHANNEL RECEPTION ARE NOT MET. IN PARTICULAR, A NEW VARIABLE CALLED HS_DSCH_RESEPTION_GENERAL IS SET TO FALSE IF A NEW CELL FOLLOWING A CELL RESELECTION OR A NEW STATE FOLLOWING A STATE TRANSITION DOES NOT SUPPORT HS_DSCH_ RECEPTION. STOP HS_SCCH RECEPTION. STOP HS-DSCH RECEPTION. CLEAR RNTI. RESET MAC_HS. RELEASE HARQ RESOURSCES. SET HS_DSCH_RESEPTION_GENERAL TO TRUE IF HS_DSCH IS ONGOING. CELL_FACH, CELL_PCH, URA_PCH AND CELL_DCH.

    Abstract: A wireless transmit receive unit (WTRU) is configured to operate in an high speed data packet access (HSDPA) mode in a cell and/or state and to clear HSDPA resources when moving out of the cell and/or state. The WTRU is configured to clear HSDPA resources when conditions to perform high speed downlink shared channel reception are not met. In particular, a new variable called HS_DSCH_RESEPTION_GENERAL is set to FALSE if a new cell following a cell reselection or a new state following a state transition does not support HS_DSCH_ reception. Stop HS_SCCH reception. Stop HS-DSCH reception. Clear RNTI. Reset MAC_hs. Release HARQ resoursces. Set HS_DSCH_RESEPTION_GENERAL to TRUE if HS_DSCH is ongoing. Cell_FACH, Cell_PCH, URA_PCH and Cell_DCH.
